Gene therapy is the use of genetic information to alter deficits and diseases within the organism and it can now officially be claimed responsible for creating a biological pacemaker in a pig. Pig hearts are much like human hearts, which would explain their extensive use in experiments and research. This research alters the muscle cells in the heart to provide a regular heartbeat.

The experiment was conducted using pigs suffering from a condition known as heart block suffer. This makes the heart beat slowly, thus the animals were injected with a normal human gene in a tiny portion of their heart and fascinatingly muscle cells responded by delivering regular electrical signals so the heart could beat normally.

The research used an adenovirus to merge the human gene with the pig’s genetic code otherwise the pig’s defense mechanisms would kick in and its system would reject the human gene entirely. 10 percent of all the respiratory problems in children are caused by these viruses and they are a common cause of diarrhea. However the researchers believe that it is safe to use the virus for this process.

It is perhaps obvious that the virus would involve some risk but the utility of the result definitely outweighs the risks involved. The implications of this experiment could mean that one day mechanical pacemakers could be replaced and the patient could have a healthy heart again. The gene used in named TBX18 and it works by coding for a protein that assists in regulating the timing of the heartbeat. Pigs in the study responded to the treatment in just two days by developing a faster heartbeat. If the treatment can be applicable to humans it may be the solution to many troubling issues that concern heart treatment. For example; the physiological immaturity of fetuses disallows them from receiving mechanical pace makers, with this treatment the gene could be delivered to the fetus via an injection through the womb.

Mechanical pacemakers have to be replaced and it is not uncommon to develop an infection (1 in 50 pacemaker recipients) because of the pacemaker as it is an external object inside the body. This therapy could solve these medical problems and the patient could be cured of a fatal condition with just a single gene injection!

Dementia is like a ghost for everyone these days since there is no treatment for it and in extreme case it can also cause death. People often mix the two terms dementia and Alzheimer which is wrong, they are not that much similar diseases.

Vergesslicher Mann

Some people worries more about it even when they forget where they have kept their money and they remember it after few hours. They begin to consider themselves an early stage patient of dementia but they are not aware of the fact that it can merely be confirmed through certain tests. Even the early phase of dementia comes with bigger problems than all these stuff forgetting things.

You should begin to worry when you do not even recall the things you have forgotten. The worst part of dementia is that it can cannot be cured in older age and only way to avoid it is to alter your lifestyle for instance take healthy food, do exercise as often as possible, throw out all the cigarette packets from your life, try to get better education etc. Yes! The option of better education surprises everyone a bit but it is verified through research. As far as the healthy food is concerned, it is said to cut down obesity from your life which is only achievable when you change your diet. This alteration in diet should also have some less amount of sugar of sweet since diabetics is regarded as the major source of dementia.

Targacept Inc has recently announced that it will not proceed with its Alzheimer’s drug trial because of apparent mid-stage trial failures. The reasons seem to be that it doesn’t exhibit an edge over standard Alzheimer medication which has had a significant impact on the company’s shares sending them down as much as 19.8 percent.lzheimer Drug Trials

Targacept Chief Executive Stephen Hill is reported to have said that the company no longer intends to invest in further development of TC-1734 (the Alzheimer drug).

TC-1734 was also being tested against Pfizer’s donepezil had previously also failed a mid-stage trial conducted by Targacept’s partners AstaZeneca Plc.
This new failure has had a devastating effect on Targacept, and is downright depressive for patients experiencing Alzheimer’s who were in hope of a better drug.

Atrial fibrillation is the a widespread heart problem which is an abnormal heart rhythm. It is generally linked with  palpitation, fainting, chest pain. The researchers are still working to calculate the cause of this disease.

For several years, this disease is treated through the drug digoxin, which is pulled from the foxglove plant.

Recently, a study has revealed the fact that Digoxin can increase the mortality rate in  the patients who is newly diagnosed from Atrial fibrillation. Even if a person remains untreated than there are probabilities that he can survive more as compared to the patient who takes digoxin. It immediately escalates the hazard of heart stroke and heart failure in the patients.

This survey has been carried out between 2003 and 2008  and demonstrated that 70 percent of the 23 percent patients who were recommended digoxin continued to hold it for another twelve months. On the whole there were almost 122465 patients included in this experiment  and eventually they helped the experts in the formation of a conclusion.

As stated by the The American Heart Association and American College of Cardiology Foundation doctors should not consider digoxin as the first therapy to cure this ailment. Though it cannot be said that digoxin is entirely useless, it can be extremely constructive for the patients with heart failure.

According to Turakhia, the study author this report filled the chief evidence gap in the management of atrial fibrillation. Its outcome is not as the usual experiment of atrial fibrillation since digoxin was used for decades for the treatment of Afib patients. The study indicates that almost 3 percent patients are more at risk of dying due to digoxin.

According to the study conducted by the team of St. Michael’s Hospital in Toronto, Canada head by Dr. David Jenkins, a low-carbohydrate vegan diet – named as “Eco-Atkins” is effective for weight loss.

Now the team found out that the “Eco-Atkins” may also reduce the risk of cardiac disease by 10% over 10 years.

Dr. Jenkins research resulted that many low-carbohydrate diets have been associated with weight loss. But he notes that most of these diets include eating animal proteins and fats, which can increase cholesterol.

But the diet having high vegetable proteins and oils have been allied with a reduced risk of heart disease by reducing low-density lipoprotein (LDL the “bad cholesterol”. LDL cholesterol builds up in the walls of blood vessels narrow the walls and cause blockages, resulting increases the risk of heart disease.

Eco-Atkins diet – It consists of low carbohydrates and high vegetable proteins and oils food, the team wanted to see whether it could reduce heart disease risk.

Eco-Atkins diet

Experiment:

The researchers evaluated 39 overweight men and women between April 2005 and November 2006.

They were divided into two groups:

Group A- followed the Eco-Atkins diet for 6 months.
Group B- followed a high-carbohydrate low-fat diet for 6 months.
Those who followed the Eco-Atkins diet have to eat around 60% of their estimated caloric requirements that should be consumed each day to maintain their current weight.

Group A were told they should intend to get 43% from fats, 31% from proteins and 26% of calories from carbohydrates. Mainly from vegetables and vegetable oils.

Observation:

At the end of the research tenure, the team found that Group A, who followed the Eco-Atkins diet had 10% lower cholesterol and lost an average of 4 pounds extra weight, compared with Group B, who followed the high-carbohydrate, low-fat diet.

Conclusion:

The team calculated the reduction in cholesterol and weight as a 10% reduced risk of heart disease over 10-year period.

Dr. Jenkins and team stated that, “We conclude that a weight-loss diet which reduced carbohydrate in exchange for increased intakes of vegetable sources of protein, such as gluten, soy and nuts, together with vegetable oils offers an opportunity to improve both LDL cholesterol and body weight, both being risk factors for heart disease.

Further trials are warranted to evaluate low-carbohydrate diets, including more plant-based low-carbohydrate diets, on heart disease risk factors and ultimately on heart disease.”

High-fiber food:

Oats and barley, formed part of the Eco-Atkins diet, as did low-starch vegetables, including okra and eggplant. Sources of protein came from vegetables, nuts, cereals, gluten and soy while the main fat sources were vegetable oils, nuts, and avocado and soy products.
