Study 187 :Cognitive Studies – Males and Females Aged 18 and Above

Medical & Clinical Trials

Type of Study

The MRI will take images of your brain that show what areas are working when you think. For these studies, you lie inside the MRI scanner and are asked to perform mental tasks, while the scanner take pictures of your brain at work. You may be strapped down to prevent you from moving during the scan. During the scan the machine makes a loud knocking sound, but you will not feel anything.

Because of the magnetic field used by the MRI scanner, you will be required to remove all metal objects from your body, including jewellery.
You will not be able to participate if you have metal implants or extensive dental work.

Great Tips

Great Tips for Clinical Trials and Medical Trials Volunteer

great and helpful tips

Your Mother Tongue.

If you are reading these ‘helpful hints’ without problem, then it probably means that you speak and read English to quite an advanced level. This will most certainly work in your favour when approaching clinics. The majority of clinics will only accept volunteers that speak the language of where the clinic is located. By accepting volunteers who speak a foreign language, clinics may be over complicating their application process. They will need to translate consent forms, clinic rules etc. Being fluent in English will be of great help .

Get yourself a GP.

When being recruited onto a medical trial, it is likely that you will be asked to provide your medical history. It is vital for the clinics to ensure that all information provided is legitimate, as any false information could lead to fatal consequences. By providing the contact details of your local GP (general practitioner), the clinics can validate your medical history. In the UK most clinics will require a 6 to 12 month doctors registration from your home country or in the case of Cambridge , Scotland and Ireland at least a 3 month doctors registration in the UK .

However, if you are not British, it is likely that you will not have a local GP. Still, there are up to 4 possible ways you could satisfy this requirement.

  1. You can register with a local GP at no cost under Britain’s NHS system. The process includes a routine health check, and is a simple matter for those holding Commonwealth or EU citizenship, who are therefore entitled to reciprocal health care. If you are not a Commonwealth or EU citizen, then you may have to visit several practices before you find one willing to accept you as an NHS patient. You might have to state your intention to live in the area for at least six months, and explain your need to satisfy the clinic’s requirement that you provide them with a doctor to contact. Do not register as a “temporary patient”, if you do you won’t have a health check or a complete set of medical records on file, and some clinics may find this unacceptable. Remember also that you are supposed to register with a GP in your catchment area, so you should provide a nearby legitimate address where they will be able to send your NHS card or any other correspondence. In addition, be sure to give them a phone number they can contact you at regarding appointments etc.
  2. Most clinics will accept the contact details of your doctor from your home country.
  3. Another possibility is to provide the contact number of a clinic at which you have taken part in trials before. This is probably only an option if you successfully completed multiple trials there in recent years, and if they keep files containing your medical history in their volunteer database. Be aware, however, most clinics do not retain this information. It also helps if there is a doctor or volunteer recruiter there who would know you.
  4. As a final resort you may consider registering privately. This can cost up to £60, depending on the doctor that you go to.

Be persistent.

You should be aware that not all clinics are big operations that staff full-time volunteer recruiters. This means that it may be necessary for you to phone them more than once, as they may not get back to you straight away. Being persistent may pay off but don’t be so persistent that you become an annoyance.

Blood donation.

If you have decided that you want to do a medical trial, then it is probably not a good idea to donate your blood or plasma as blood donations can leave you very anemic and you will not be allowed to participate in both although you could donate blood and participate in non systemic or non invasive research without any problems .

Poppy seeds.

Be sure not to eat any foods containing poppy seeds before or during a trial as they can cause a positive result to a drug test.

Passive smoking.

You may think that if you are around people that smoke drugs but you are not actually smoking them yourself, you will not test positive on a drug test. This is not true. If you are around people who smoke marijuana or hash, then this can show up as a positive result in a drugs test as you have received the smoke passively.

Too much alcohol?

Try to refrain from going on drinking binges for up to a week prior to your trial. Although the alcohol will leave your system, your blood may still be thinned from the affects of the substance thus causing abnormal results in a blood test.

Are you local?

It is a requirement of some clinics that the volunteers are of local residency, which usually means coming from within 50 miles/ 80 km. If you are not a permanent local resident, then a perfect solution may be to book into a local backpackers hostel as this can be provided as an address. Most will require a passport for proof of travel.

You should however be aware that some clinics will require you to be a permanent local resident which means that the hostel address where you are staying will not be considered to be acceptable. Most clinics in the UK will accept volunteers from far and wide and the major concern is usually if you are from afar that are you going to be reliable . Most clinics find volunteers with a local address to be a far safer bet .

Make sure that you are expected.

You may need to provide a proof of the address where you are staying, so you should think about this in advance to your arrival at the hostel or at your friends house.

The clinics may also want to call you to change or confirm information regarding your trial. For this reason, it is important to inform the hostel or your friend that you are coming, so that they can take messages on your behalf.

Smokers vs. non-smokers.

If you are taking part in a trial that is recruiting non-smokers, you should remember that being a non-smoker really means having given up for a period of 90 days , rather than being someone who just has a couple here and there., you are still a smoker.


Competition can sometimes be fierce when in the screening process. This is mostly true when the study you are going for is recruiting from the most popular clinics and are paying the most amount of money. Some clinics unfortunately take advantage of the volunteer’s competitive side by falsely stating that the amount of subjects they wish to recruit is actually higher than it is. This makes the odds of being accepted seem higher which means that the clinic will get a higher response of people applying. This allows the clinics to be pickier with whom they choose. However, you shouldn’t let this put you off as it could well be you that is the ‘perfect volunteer’.

Being a reserve subject.

Most clinics are honest and will inform you fully on your recruitment position. However, some clinics will tell you that you have been accepted to be a volunteer to only tell you on the day of the trial that you are a reserve subject. This means that for you to take part in the trial, the other subjects must fail a blood test, be dropped for medical reasons or fall in a ditch on the way to the trial. Thankfully, most clinics will inform you up front whether or not you are a reserve subject and many will pay you for your inconvenience regardless. There not too bad really.

Read and be sure.

Ok, so we have all had a long, boring contract put in front of to be read for us only to sign it without paying our full attention. However, it is of the utmost importance for you to read your informed consent form as if there is something that you are not sure about, you need to ask questions.

Keep the bugs away.

You should do everything in your power to prevent yourself from getting ill before trial. Eating fruit rich in vitamin C, such as oranges and kiwi fruit can help keep infections away. Also good at preventing colds are zinc (found in non-processed meat), and garlic (especially if eaten raw). Alternatively, you can find supplements of these in any health store or pharmacy. You can also use certain kinds of herbal extracts, the most popular being køb melatonin. It pays not to take vitamin tablets and in particular St Johns Wort for a min of 2 weeks prior to participation . We need you squeaky clean for safety reasons .

Don’t mix your drugs.

If you take other medication close to or during a trial, this could result in serious injury. If there are medications that you must take for health reasons, you should inform your trial organiser.

Pulling out.

As a volunteer, you are able to pull out of most studies at any point. However, by doing this, you may be blacklisted from future studies as clinics look for volunteers who are reliable. Most clinics will tolerate you pulling out a first time but will probably not tolerate it a second time. You should aim to give the clinic as much prior notice as possible when you decide not to complete the study. However, do not simply not turn up as this will almost certainly result in you being blacklisted.

Get a back-up plan.

A study and the study dates are not always set in stone. Therefore it may be sensible for you to have a back-up study that you can participate in. At some clinics, studies are cancelled or pushed back with alarming frequency.

Be on your best behaviour.

Behaving aggressively or complaining too loud will not do you any favours in the clinic. Try to keep your complaints down to a minimum and keep your eyes on the prize.

Mutiny on the unit.

Don’t circulate petitions (or sign them) protesting your pay, or restrictions on the unit. Remember you agreed to these when you agreed to take part in the study. Usually this behaviour will get you banned from the clinic in the future.

Flexibility helps.

It has been known for clinics to change the dates of trials and screenings etc. Dates can change for a number of unforeseen reasons. For this reason, it is beneficial if you can be flexible with when you can go into the clinic.

Exchanging lists.

If you are asked by another volunteer to exchange your list of clinics be sure to check the legitimacy of the list, as some volunteers have been known to change just one digit of all of the phone numbers to prevent anyone phoning the clinics. How dare they.

Take your medicine.

Be sure to follow your instructions precisely and do not ‘cheek’ your medications as you will probably be found out as it will lead to inconsistent results in any tests preformed.

Do as you’re told.

Make sure that you follow any rules laid down by the clinics as the results from not doing so may be getting fined, the clinic withholding your bonus payment or perhaps an immediate discharge.

Replenish your blood.

If you have participated in trials that have involved many blood draws, it is important for you to replenish your red blood-cell count. You can do this by taking iron supplements or eating iron-rich foods such as liver, spinach, and shellfish. Washing your food down with orange juice helps your body absorb the iron easier and quicker.

Flush your kidneys.

You can flush out your kidneys, before and after a trial, by drinking plenty of water as well as herbal tea, lemon juice, and cranberry juice.

In between trials.

You should be aware that in England you can expect to have up to a 4 month wait until you are allowed to be recruited onto the next trial. Most UK clinics have a 3 month waiting period as the average clinical trial can take as much blood as the average blood donation . This is UK blood donation law rather than a safety thing . This is different to how the American’s do it, as they usually only have to wait up to 30 days and this is considered to be enough time to replenish . However, depending on the drugs that you tested and the type of trial that you participated in, you may not have to wait the full 3 months.

Remember you manners.

When having a phone interview or a prior screening, it always pays to be polite and clear-headed. If the clinic has a large quantity of people volunteering, your personality may be a key factor in your recruitment.

Use common sense.

The very nature of medical trials means that it is vital for you to apply your own common sense when approaching a clinic or medical trial. It is not rocket science to be a volunteer but you will need to be sensible.

Asthma Introduction


What is asthma?

Asthma is a variable condition that affects the airways – the small tubes that carry air in and out of the lungs. People with asthma have airways that are sensitive and become inflamed.

Their airways can react badly when they have a cold or other viral infection, or when they come into contact with an asthma trigger (a trigger is something that sets off asthma symptoms – see section below)

When this happens the muscles around the walls of the airways tighten and they become narrower. The lining of the airways swell and often produce a sticky mucus. As the airways narrow, the air has to squeeze in and out, and this is what causes difficulty in breathing. Asthma symptoms can include coughing, wheezing, shortness of breath or a tight feeling in the chest.

Asthma affects millions upon millions of people throughout the world , including one in eight school children and one in 13 adults. With the correct treatment, support and advice, most people with asthma can lead full and active lives.

What are the causes of asthma?

Asthma, like its related allergic conditions eczema and hay fever, often runs in the family and may be inherited. There are probably a number of other, environmental, factors that contribute to someone developing asthma – many aspects of modern lifestyles, such as housing and diet, might be responsible. We also know that smoking during pregnancy increases the chance of a child developing asthma. Poor air quality can make your asthma worse.

What are the things that can set off (or trigger) asthma symptoms?

A trigger is anything that irritates the airways and sets off the symptoms of asthma. Common triggers include colds or flu, cigarette smoke, exercise and allergies to things like pollen, furry or feathery animals or house-dust mite. Everyone with asthma is different and has different trigger factors.

Asthma symptoms include:

• shortness of breath,
• wheezing (a whistling noise in the chest),
• cough and chest tightness.

Not everybody will have all these symptoms. Young children often present only with a cough with no other symptoms hence often the asthma diagnosis is overlooked or misdiagnosed. A history of asthma, eczema or hay fever in the family may mean that your chances of developing asthma are slightly higher than those without.

If you suspect that you may have asthma, it is important to see your doctor or asthma nurse. They will discuss your medical history and your current symptoms. They may want to measure your peak flow using a peak flow meter. This measures the amount of air you can blow out of your lungs in a fraction of a second.

Each time you use the meter (usually morning and evening) the result is marked on a chart. It can help (along with keeping a record of your symptoms) to give the doctor a better picture of how well controlled your asthma is. The doctor may decide to give you your own receptfria sömntabletter and peak flow meter and ask you to keep a diary of readings. They will be able to assess the pattern from the readings and observe the variability between the morning and evening measurements which is a good indicator of asthma control.

Most GP practices / Asthma Nurses perform spirometry testing ( blowing tests) Spirometry testing may assist in diagnosing asthma.

Is there a cure for asthma?

Currently there isn’t any cure for asthma. However, a considerable amount of research into asthma is being conducted out all around the world.

Researchers are tackling asthma from many directions: indoor and outdoor air pollution, allergies, gene therapy, cell biology and chemical structures to name but a few. The results of their work will help us understand much more about how and why this common condition develops. It might also lead to even more effective asthma treatments – and an even better quality of life for everyone who has asthma.

Current research suggests that taking certain preventative measures in the home can lessen your chances of developing asthma, or reduce your symptoms. These steps include reducing the amount of dust in your home and can be achieved using simple measures like damp dusting and opening windows.

Asthma treatments

Although there is no cure for asthma, there are many safe and effective asthma treatments available that can help to control your symptoms.

Asthma Control

The aim of your asthma treatment is to keep you free from asthma symptoms during the day and the night and to reduce the amount of time that you have to take off work. If any of the points below apply to yourself then it indicates that your asthma is not adequately controlled and you should consult your GP or asthma nurse.

Signs of poor asthma control include:-

• Night time awakenings with coughing, wheezing, shortness of breath or a chest tightness
• being short of breath on waking up in the morning
• needing more and more reliever treatment, or reliever not working very well
• being unable to continue your usual level of activity or exercise
• finding that you are too breathless to talk or eat

There are two main kinds of asthma treatment that your doctor may prescribe for you. They are called relievers and preventers.

Everyone with asthma should have a reliever inhaler. Relievers are treatments taken to relieve asthma symptoms. They quickly relax the muscles surrounding the narrowed airways (within 5-10 minutes), making it easier to breathe again. Reliever inhalers are usually blue in colour and are often referred to as the “blue inhaler”.

If you need to use your reliever inhaler more than once in any day, or more than 3-4 times a week, you will need an additional preventer treatment to keep your asthma symptoms under control. This is because relievers do not reduce the inflammation and swelling in the airways there fore are not treating the underlying cause.

Do treatments have side effects?

Reliever treatments are very safe and effective and have few side effects. Sometimes, high doses of reliever treatment can slightly increase your heart beat or give you mild muscle shakes. These effects are harmless and generally wear off after a short period of time.


Preventers help to control swelling and inflammation in the airways. They also stop the airways from being so sensitive to asthma triggers. The protective effect of preventer treatments builds up over a period of time. The full effects when starting on a preventer inhaler are not achieved for several weeks so it is important to keep taking them even when you feel better.

If you take your preventer treatment regularly you will improve your long-term chances of controlling your asthma and reduce the likelihood of permanently damaging your airways.

Preventer inhalers are usually brown, red or orange.

What about side effects?

Preventer treatments usually contain corticosteroids (a copy of the steroids produced naturally in our bodies) in low doses. These steroids are safe, not addictive and are completely different and not to be confused with the anabolic steroids used by body builders and athletes.

Using a preventer inhaler brings a small risk of a mouth infection called thrush and hoarseness of the voice. You can avoid this by using your inhaler before brushing your teeth and by rinsing out your mouth afterwards. Using a spacer device will also reduce the chances of these side effects. A spacer device also gives a much better delivery of the drug and delivers it to your lungs more effectively.

How do I take my treatment?

One of the most common ways of taking your asthma treatment is to use an inhaler device. Inhalers are useful because they help to get your treatment straight to the airways where it is needed. Inhalers can be in a spray form (aerosol) or dry powder form. If you use an aerosol inhaler, using a spacer device with your inhaler can also help.

Inhalers and spacers can be tricky to use at first and good technique is important in getting the most from your medication. Ask your doctor or practice nurse to check you are using your inhaler correctly the next time you see them.

Steroid tablets

Sometimes, when your asthma is first diagnosed, or if you have had a bad asthma attack, your doctor may give you a short course of a tablet form of preventer treatment (steroids). These tablets will help you to gain control of your symptoms quickly.

Add on treatments

If your asthma symptoms are not controlled by regular inhaled preventer and ‘as needed’ reliever, you may be prescribed an add on treatment to take in addition to your relievers and preventers.

The add on treatments currently available are:

Long acting reliever inhalers

The effects of these inhalers are similar to the blue reliever inhalers but the effects last for approximately 12 hours so are taken morning and evening on a regular basis along with the preventer inhaler.

They help to control symptoms by relaxing the muscles of the airways to keep the airways open.

As both the long acting reliever and the preventers are both taken morning and evening they are sometimes available in a combination 2 in one inhaler for convenience.

Preventer tablets

If your asthma symptoms are not controlled by regular inhaled preventer and ‘as needed’ reliever, you may be prescribed a daily preventer tablet treatment. These are not steroids and are usually taken alongside inhaled preventers to try and control symptoms if they are still present after the first lines of treatment mentioned above have been taken.

About Asthma attacks

Sometimes, no matter how careful you are about taking your asthma treatment and avoiding your triggers, you may find that you have an asthma attack. Most people find that severe asthma symptoms are the result of a gradual worsening of symptoms over a few days.

If your asthma symptoms slowly get worse – don’t ignore them! Quite often, using your reliever is all that is needed to get your asthma under control again. At other times, symptoms are more severe and more urgent action is needed. Your asthma nurse or Doctor can help you devise an asthma action plan so that you know what to do in the event of a worsening of asthma and how to recognise the signs.

What to do if you have an asthma attack

1. Take your usual dose of reliever straight away, preferably using a spacer
2. Keep calm and try to relax as much as your breathing will let you. Sit down, don’t lie down. Rest your hands on your knees to help support yourself. Try to slow your breathing down as this will make you less exhausted
3. Wait 5-10 minutes
4. If the symptoms disappear, you should be able to go back to whatever you were doing
5. If the reliever has no effect, call the doctor or ambulance
6. Continue to take your reliever inhaler every few minutes until help arrives preferably using a spacer. It is safe to keep taking your reliever inhaler until help arrives.

Do not be afraid of asking for help, even at night. A severe asthma attack can be life threatening and must be treated promptly.

If you are admitted to hospital or an Accident & Emergency department because of your asthma, take details of your treatment with you. You should also make an appointment with your doctor or practice nurse after you have been discharged from hospital so that you can review your asthma treatment and devise a plan if you didn’t previously have one so that you know what to do if the situation arises again.


Diabetes Introduction


Diabetes is a common condition. It develops when the amount of glucose in the blood is too high because the body can’t use it properly. Diabetes can lead to serious conditions such as stroke, circulation problems, and damage to the kidneys and eyes.
Medically known as Diabetes Mellitus, symptoms include thirst, a frequent need to pass urine (especially at night), extreme tiredness, weight loss, genital itching or regular episodes of thrush, and blurred vision. There are three main types: 1, 2 and gestational. If diagnosed early enough, most people with diabetes can handle their condition by a combination of lifestyle and medical interventions. But there is no doubt medical advances need to be made.

What is diabetes?

Diabetes occurs because some people do not make, or cannot respond to, their natural hormone insulin. Hormones help us control the way our bodies work. Insulin’s specific job is to regulate the body’s use of glucose, our main fuel source. We get glucose, a form of sugar, from the food we eat. It is also made by the liver

In Type 1 diabetes very little or no insulin is made and lifestyle changes cannot alter the condition. Patients need to monitor their blood glucose levels and administer insulin injections several times daily. This type of diabetes generally develops in younger people, and affects both sexes equally.

Type 1 diabetes develops when cells that make insulin have been destroyed by the body’s own immune system. There is a genetic risk to diabetes – it tends to run in families. The environmental factors that might trigger such a destructive process, possibly viral, are not well understood.

Type 2 diabetes

In type 2 diabetes, either the body makes some, but not enough, insulin or it cannot use the insulin it does make. Patients may not need insulin injections.

Type 2 diabetes is associated with lifestyle factors such as increased weight and a sedentary lifestyle. It used to be called ‘late onset’ because it usually appears in middle-aged or elderly people. It’s also been wrongly described as ‘mild’ diabetes. There is no such thing. All diabetes should be taken very seriously.

At least three quarters of the estimated 150 million diabetics world-wide have Type 2. It is increasing alarmingly. The World Health Organisation expects numbers to double to over 300 million by 2025.

Gestational diabetes

Pregnancy affects blood glucose levels in all women and, as its name suggests, gestational diabetes is linked to pregnancy. If diagnosis is made during the first three months, then the expectant mother was most probably diabetic already. However, when the diabetes starts after three months, it is thought to be other hormones from the placenta interfering with insulin action.

Diabetes in animals

Insulin, the hormone at the heart of diabetes.
Roughly one in every 500 dogs or cats has diabetes. Onset is usually in older animals, typically over seven for dogs and over five for cats. Burmese cats are known to be genetically predisposed to diabetes. One in ten over eight years’ old will develop the disease. Guinea pigs and rabbits also contract the condition. Like humans, some diabetic animals can improve with insulin and a controlled diet. Others need medicines, the ones that were first developed for humans.

What happens when the body cannot control glucose production?

Our bodies digest sugar and starchy foods to make glucose. This glucose is released into the blood and stimulates the pancreas to make insulin. Insulin controls the amount of glucose in the blood by allowing it to move out of the blood into cells. Once inside cells, glucose is converted to energy, either to be used immediately or stored.

Insulin, the hormone at the heart of diabete

eople with diabetes do not have enough insulin or it does not work properly, so their ability to convert glucose into energy is impaired. The body recognises it lacks energy and stimulates the liver to make more feedstock for energy – glucose. But the patient’s insulin problem means this extra glucose still cannot be converted. The next option for the body is break down its stores of protein to try and release yet more, but unfortunately still unusable, glucose. This is why untreated diabetics often feel tired and lose weight. The body gets rid of glucose in the urine, which explains the need to pass large amounts of urine and the extreme thirst from the dehydration that follows.

The impact of diabetes

Foot problems are among the many serious complications that can result from diabetes. Nerve sensations in a patient’s foot being tested.
People with diabetes are significantly more likely to develop serious health problems like heart disease, stroke, high blood pressure, circulation problems, nerve damage, and damage to the kidneys and eyes. Disease of their leg arteries greatly increases the risk of exercise pain, gangrene and amputation. Kidney damage, for example, may develop in about one-quarter of all people with the condition, and this can lead to kidney failure and the need for dialysis or kidney transplantation. Diabetes is the single most common cause of blindness in adults of working age. The risks are made even worse if the patient is overweight, smokes or is not physically active. According to one study, diabetes accounts for some 9 per cent of the annual NHS budget.

Thanks are due to Professor Frances Ashcroft (Oxford University), Professor Anthony Barnett (Birmingham Heartlands Hospital), Professor Don Chisholm (Garvan Institute) and Diabetes UK.

Diabetes – Current Treatment All diabetics can reduce the risk of complications by controlling blood glucose and blood pressure levels, healthy eating practices, maintaining physical activity, and by regular medicals.

First, people with diabetes need to eat a healthy diet that contains the right balance of foods. People with type 1 diabetes also need daily injections of insulin for the rest of their lives. If diet and regular physical activity does not control type 2 diabetes, there are several different sorts of tablets to help. Some, such as the sulphonylurea drugs and prandial glucose regulators, stimulate the pancreas to produce more insulin. Metformin helps to stop the liver making new glucose and also makes insulin more effective. Acarbose slows down the absorption of starchy foods and, therefore, the rise in glucose level after a meal. While the newest class, the thiazolidinediones, overcome resistance to insulin. More than one kind of medicine may be needed to control the amount of glucose in the blood, and, like people with type 1 diabetes, type 2 sufferers may eventually need insulin injections.

How did we get these treatments?

Without treatment, diabetes is a long-lasting, wasting disease that inevitably leads to death. That inevitability began to change in 1921 when insulin, and its ability to treat diabetes, was discovered. Insulin was found to lower blood glucose in a dog that had been given diabetes by removing its pancreas. Once the medical value of insulin had been established in the dog, attention turned to purifying it so it could be given safely to patients. Insulin has been used to treat diabetes ever since. For a long time, insulin was purified from cows and pigs killed for food. It was not until the 1980s that human insulin, genetically engineered from bacteria or yeast, became available.

The first class of oral diabetes medicines was discovered, unexpectedly, at the time of the second world war. Several typhoid patients died who had been given a new antibiotic. The cause was found to be low levels of sugar in the blood. Studies in dogs showed that the antibiotic had decreased glucose levels. Though clearly fatal for some, this might, it was thought, be beneficial for people with diabetes.

The antibiotic was not suitable to become a diabetes medicine, so the search was on to find similar-acting chemicals. Candidate molecules were tested first in animals and then humans until, in 1956, a sulphonylurea usable against diabetes – tolbutamide – was identified. As understanding grew as to how sulphonylureas produce insulin and reduce blood sugar levels, more of them were developed.

The next advance came via the herb Goat’s Rue or French Lilac. This had been known for centuries to have natural benefits for diabetics but it is too toxic to make a satisfactory medicine. The active ingredient in Goat’s Rue – guanidine – was the inspiration for Metformin. Metformin became available for diabetics in the 1970s, it is often of particular value for obese patients. Driving the development of the thiazolidinedione class was the need to enhance the action of insulin for type 2 diabetics.

In addition to understanding how the body makes insulin normally and uses it to convert glucose into energy, there was research into how the disease itself strikes. A great deal of this work can be done with cells and tissues, but at some point researchers will need to have insights into how the part of the disease they are examining proceeds in a living creature.

Although insulin and today’s medicines make a huge difference to patients’ lives, blood glucose levels can still fall too far, causing ‘sugar lows’ (hypoglycaemia).
Symptoms including feeling shaky, sweating, tingling in the lips, going pale, heart pounding, confusion and irritability can result. If hypoglycaemia is not treated with a quick sugar ‘fix’ and a more substantial snack, it can lead to loss of consciousness. Therefore, ongoing research is looking both to understand how insulin operates normally and in disease and for better treatments for diabetes.

An ideal treatment for diabetes might be to provide new pancreas islets, (these are where the beta cells that make insulin are found). Some patients have already received cell transplants from donors. But there are two problems: not enough donors and patients need to receive immunosuppressive drugs for the rest of their lives.

Genetically engineering the patient’s beta cells and putting them back in the pancreas might offer an alternative. A different approach is to convert liver cells into pancreas cells. Another possibility is to use stem cells. These are the relatively non-specialist cells found, for example in bone marrow, that become specialised. There has been some success in making beta-like cells that produce insulin in response to glucose. We are a long way from using engineered cells in treatment. One vital aspect will be to understand how the pancreas, the insulin factory, develops.

It has been know for some 20 years now that the protein Ptf1a is involved in the development of the pancreas. By comparing normal mice and mice bred without this protein it has been found Ptf1a helps cells to decide what they will become. It is turned on very early in all the cells that will eventually form the pancreas and then switches off in those pancreas cells that will eventually go on to make hormones like insulin.

Perhaps Ptf1a could be used to turn stem cells into pancreas cells, which would form part of the cell transplant process for diabetics.

Other research is concentrating on new targets for medicines  and that includes köpa melatonin for example, what hinders the beta cells in the pancreas from releasing insulin? One culprit is an enzyme called DPP-IV which breaks down proteins that stimulate the release of insulin. Therefore, a medicine that inhibited DPP-IV might be able to treat diabetes in a new way. Finding chemicals that stop DPP-IV from working in the test tube is reasonably easy. But that does not mean in a patient they will be any good.

Medicines have to be swallowed or injected, they have to travel to their target, they have to avoid being turned into something toxic or into something that loses its effectiveness.

Volunteer FAQ’s

FAQ’s – Learn more volunteering for medical trials and medical research.

Your Clinical Study Infomation Resource


1) Q: What is a Non Invasive Medical Research?

A: Non Invasive Medical Research means there are no invasive procedures involved . That means no drugs to be internalized or needles etc . A typical non invasive research study would include cognitive tests for motor function or psychology pen and paper tests.

2) Q: What is a Phase 1 Medical Trial?

A: This is where medications are being tested for the first time in people after many years of pre-clinical research . This research is usually performed on animals and also very stringent laboratory tests to insure the maximum safety of healthy research participants . There are no health benefits to participating in healthy volunteer medical trials and consequently the reason for your payment for time and inconveniences incurred . There is always the knowledge and greater purpose that in some way you have aided towards reducing the suffering of less fortunate people . The risks involved with Phase 1 Medical Trials can be likened to crossing the street . You could get hit by a bus although its unlikely , but there are things you can do to prepare yourself for medical trials to further insure your ultimate safety .

3) Q: What is a Phase 2 Clinical Trial?

A: This is where a small number of patient volunteers are enrolled onto studies after it has been established that the medications are tolerable in humans and can now be passed onto patient volunteers to see if any likely benefits are apparent for the patient population concerned . This usually involves a very small number of patients .

4) Q: What is a Phase 3 Drug Trial ?

A: This is where a very large number of patients are used to assert improvements in lifestyle in a broader selection of people . Usually trials that make it to Phase 3 Testing will be approved by the authorities for the marketing of the new drug . Once that trial is finished you will be able to sömntabletter receptfria or another similar drug you have tested.

5) Q: What is a Phase 4 Medical Trial?

A: These can be conducted through general practitioners or professional testing centers . The drugs are already approved by the authorities but make be looking at different applications or whether or not the drug is better administered in powder form as opposed to tablet form . Generally speaking Phase 4 Trials are the safest of any medical testing as so much more is known about the medications.

6) Q: What sort of drugs do they test on healthy people, and why?

A: Every drug, in any form, whether prescription or over-the-counter, has to be approved by a government regulatory agency before it can be made available. In order for a drug to be approved, it must be deemed both safe and effective. The drug is first tested in laboratory animals (example: rats, guinea pigs) to determine if it is safe enough to be tested in humans.

If safety is determined to an acceptable degree, then trials with humans are conducted using very low dosages of the drug. This is necessary to obtain specific information about the drug, for instance, the rate at which it is absorbed, metabolized, and passed out of the body, how it affects blood pressure, heart rate, etc. and what dosage can be given to subjects before they begin to experience minor side effects such as headache, sleepiness, or dizziness. Many such trials do not involve “experimental” drugs. Instead, they test medications which are identical to or very similar to those already approved and available on the market. This is necessary to learn how a marketed drug compares to a newly developed generic equivalent, to learn how two marketed drugs interact when taken together, or to investigate new formulations of a marketed drug in an effort to improve it.

The first phase of human testing usually involves healthy people who act as control subjects. This is necessary to learn how a drug reacts in a healthy person as compared to a sick person for whom the drug is intended. Healthy volunteers are paid for their time as an incentive for them to participate, since there is no expectation that they will benefit from taking the drug.

7) Q: Aren’t these trials considered risky or even dangerous?

A: Not all medical trials contain an element of risk , But where regulatory oversight exists to safeguard the treatment of research subjects, and where drug companies and testing clinics can be held liable for injuries which may occur , they are very careful to keep all risks to an absolute minimum .

It is true that until the late 1970’s, taking part in such trials contained larger risk because researchers were not obligated to provide accurate information about the drug being administered. In addition, the subject population consisted mainly of prisoners who took part in trials in order to gain early release, and conscientious objectors in the military who wanted to avoid combat duty. As such, participation in trials was motivated by coercion, and thus subjects were not necessarily “volunteering” of their own free will.

In the late 1970’s and the 1980’s, research involving human subjects in most developed nations came under scrutiny. Protective legislation was enacted as a result, and ethical guidelines were established to ensure the professional conduct of researchers. Subjects began to be recruited from the general population and to be paid for their services
