Most US women face stroke risk

Researchers in Japan have invented a tiny brain which can act as a remote control for swarms of nano-machines.They simultated eight such nano-machines to create a 'nano-factory'.According to experts,nano-machines could also be used to boost the processing power of future computers.They also have high hopes for nano-machines in treating diseases.The machine is made from 17 molecules of the chemical duroquinone.Each one is known as a 'logic device'.

Chronic fatigue syndrome(CFS) is not the same as chronic fatigue.While fatigue is a common symptom in many illness,CFS is a multi-symptom disorder.The most common characteristic being severe mental and physical exhaustion,which is 'unrelieved by rest' and may be worsened by even trivial exertion.CFS occurs more often,but not exclusively,in women,for unknown reasons. CFS is not primarily a dietary disorder but as in other debilitating illnesses,people suffering from this disease fail to consume a nutritious diet,leading to further exacerbation of fatigue and exhaustion. DIET AND LIFESTYLE MODIFICATIONS: a) Avoid excessive sugar products,which may cause dramatic fluctuations in blood-glucose levels.High or low blood sugar levels may cause fatigue.Small meals at frequent intervals should be preferred. b) Avoid excess and low salt intake.Excess salt could increase blood pressure and low salt)especially in summer months) could cause exhaustion. c) A good intake of potassium must...

The most promising of the many experimental HIV vaccines in development will offer only limited immunity against the deadly virus,US government scientists said recently ahead of world HIV Vaccine Awareness Day.Unlike classical vaccines,the first-generation HIV vaccines will not enable people to fight off the virus,but may protect their immune system from the worst ravages of the virus and dealy the onset of AIDS.And because patients are at their most infectious when viral levels are high,such vaccines might also reduce the spread of the sexually transmitted disease,making it a useful tool for public health authorities batting to contain the global HIV/AIDS pandemic."There is optimism that even a less-than-perfect vaccine could benefit both individual recipients and the at-risk community," said the authors in a commentary published in the "New England Journal of Medicine."It is still not clear when the first vaccines will be available .

Estrogen may give women an edge in resisting heart disease that can be caused in part by air pollution, a new West Virginia University study found.Researchers determined that males and post-menopuasal females are more likely to suffer damaged arteries linked to diesel exhaust than women of childbearing age.That coincides with a national study released this year showing older women are at significantly higher risk for heart problems caused by air pollution than other people.

The first dozen Parkinson's patients to have holes drilled in their skulls for a novel gene therapy attempt weren't harmed-and hints at some improvement have researchers embarking on a larger study to see if the treatment really may work.Doctors reported initial results of the closely watched experiment at a neurology meeting,but cautioned that it's far too soon to raise hopes. It helps using a nerve grwoth factor to try to resuce dying brain cells.Some 1.5 million Americans have Parkinson's, a disease that gradually destroys brain cells that produce dopamine, a chemical crucial for the cellular signaling that controls muscle movement. Too little dopamine causes increasingly severe tremors and periodically stiff or frozen limbs.

What is DVT? Deep Vein Thrombosis(DVT) is a condition in which ablood clot forms in the deep veins, usually in the legs. It could be fatal if a part of the clot breaks off and blocks blood vessels in the lugs, a condition called pulmonary embolism. Worldwide,in the last five years, DVT has claimed more lives than AIDS/HIV,breast cancer,prostate cancer and road accidents combined! Causes:DVT can be either hereditary or acquired. People with a family history should get themselves tested to figure out if they have the tendency. In cases of acquired DVT,one factor or a combination of factors like dehydration, immobility,oral contraceptive pills, hormonal therapy,etc,may be the cause. Symptoms:If the clot occurs in the brain, there's persistent headache and alteration in vision.In the lungs,there could be breathing problems. If DVT occurs in the leg,the symptoms could include pain,swelling and/or discolouration of the affected part. Prevention:According to some eminent haematologist...

Patients with type 2 diabetes are more likely to develop Parkinson's disease,although the reasons are unclear.Finnish researchers reported.They found that people with type 2 diabetes were 83% more likely to be diagnosed with Parkinson's later in life than people in the general population. This risk was the same for men and women and was independent of other risk factors. "Diabetes might increase the risk of Parkinson's disease partly through excess body weight," the researchers wrote in the April issue of "Diabetes Care".

Looking at various proteins in urine may help doctors predict the development of diabetic nephropathy in type 2 diabetes patients well before they develop the condition,according toa report in the March Diabetes Care. "We have identified a set of urine proteins almost 10 years before the onset of diabetic nephropathy that identify those who will go on to get diabetic nephropathy, the most common cause of renal failure in the US and the world," Ravi Thadani,from Masachusetts General Hospital and Harvard Medical School in Boston,said. Diabetic nephropathy is a serious complication of diabetes in which the kidneys lose their ability to function over time.

A French study says people with pacemakers suffer from a high incidence of undiagnosed sleep apnea. The study,which looked at 98 patients with pacemakers, found that 57 percent had undiagnosed sleep apnea, WebMD reported. The report, published in Circulation: Journal of the American Heart Association, says all potential pacemaker patients should be screened for sleep apnea, which is known to increase risk of cardiovascular disease. Researchers say abnormally slow heart rhythms are common among patients with obstructive sleep apnea.

Nearly all American women are in danger of heart disease or stroke and should be more aggressive about lowering their risk-including asking their doctors about daily aspirin use,the American Heart Association said on Monday in new guidelines. It is the first time guidelines have urged all women to consider aspirin for preventing strokes, although specialists warn that it can cause ulcers and dangerous bleeding.They said it is probably not a good idea for young women with no big health problems."We do not want women to go to the drugstore and just start taking this themselves. It is critical that every woman talk to her doctor."Said Lori Mosca, director of preventive cardiology at New York Presbyterian Hospital and chair of the expert panel that wrote the guidelines.
