Scientists have used a new approach to identify compounds with the potential to delay or treat Alzheimer`s disease, and possibly Parkinson`s, Lou Gehrig`s disease and other degenerative disorders.
All of these diseases are marked by harmful, elongated, rope-like structures known as amyloid fibrils, linked protein molecules that form in the brains of patients.
A compound found in soybeans can be effective in treating HIV without the drug resistance issues faced by current therapies, a new study suggests.
It`s in the early stages, but genistein, derived from soybeans and other plants, shows promise in inhibiting the HIV infection, Yuntao Wu, a professor with the George Mason-based National Center for Biodefense and Infectious Diseases and the Department of Molecular and Microbiology, said.
Still, that doesn`t mean people should begin eating large amounts of soy products.
Researchers have claimed to understand the happening in your brain when you manage to recover your balance after something unexpected happens.
Prof. Kathleen Cullen and her PhD student Jess Brooks of the Dept of Physiology have been able to identify a distinct and surprisingly small cluster of cells deep within the brain that react within milliseconds to readjust our movements when something unexpected happens, whether it is slipping on ice or hitting a rock when skiing.
Australian scientists have developed the world’s first UVA/UVB sunscreen which mimics the natural sun protection used by corals on the Great Barrier Reef.
The breakthrough paves the way for a new generation of sunscreens that harness the same protective barriers developed by Australia’s Great Barrier Reef corals over millions of years to survive in the harsh Australian sun.
The sunscreen has been developed by Commonwealth Scientific and Industrial Research Organisation (CSIRO) in partnership with skincare company Larissa Bright Australia.
A history of kidney stones has been linked with an increased risk of coronary heart disease (CHD) in women but not in men, according to a new study.
An analysis of data from three studies that involved a total of more than 240,000 participants from the National Health and Nutrition Examination Survey reported the prevalence of a history of kidney stones of 10.6 percent in men and 7.1 percent in women.
A platinum-based chemotherapy drug has upped the survival rate of British men suffering from testicular cancer by 96 per cent.
Figures compiled by Cancer Research UK show that 96 percent men have successfully been treated for testicular cancer, which is a big improvement since the 1970s when the survival rate was lower than 70 percent, the Independent reported.
Cisplatin had first been identified as a compound in the 19th century but researchers did not realise its application in oncology until the late 1970s.
A new technique using molecular robots could help develop more targeted drugs, a new study has revealed.
Sergei Rudchenko, Ph.D., director of flow cytometry at Hospital for Special Surgery (HSS) in New York City and a senior author of the study, said that the next step is to conduct tests in a mouse model of leukemia.
In the new study, which is a collaboration between researchers from HSS and Columbia University, scientists designed molecular robots that are capable of identifying multiple receptors on cell surfaces, thereby effectively labeling more specific subpopulations of cells.
Researchers have shed new light on the cellular mechanisms responsible for the ability of brain to pay attention to relevant information while ignoring distractions.
Without the ability to focus and filter out “noise,” we could not effectively interact with our environment.
Researchers from Dartmouth`s Geisel School of Medicine and the University of California Davis studied communications between synaptically connected neurons under conditions where subjects shifted their attention toward or away from visual stimuli that activated the recorded neurons .
Taking a stroll in the woods can help manage stress levels, lessen BP and help fight heart ailments, a new study has revealed.
One of the experiments, conducted by the researchers at the University of Essex, discovered that just looking at images of forests helped to reduce strains.
Dr. Valerie Gladwell led a team of scientists that carried out experiments on volunteers while measuring their stress levels.
The participants in the research were asked to walk in specified “green environments” at lunchtime slept better that night.
A new method has been developed by researchers that has the capability of looking at a specific segment of DNA and point out a single mutation, which could help diagnose and treat diseases like cancer and tuberculosis.
These small changes can be the root of a disease or the reason some infectious diseases resist certain antibiotics.
More than 5,000 doctors from all over the world will witness a live surgery to treat Obstructive Sleep Apnea (OSA), a sleep disorder, to be performed at the Asian Heart Institute (AHI) here Tuesday, an official said here Saturday.
This is the first time that such a live robotic surgery will be performed before a global audience of medicos along with expert lectures on the occasion.
Leading ENT surgeon Vikas Agrawal will operate on three patients to show the different issues pertaining to OSA among Indians.
After delivering a child, women not only fight against sleepless nights, but also body shape. To gain back a pre-pregnancy figure, use whatever time you have in hand for workouts, yoga and much more.
“The key is to do what you can in the time that you can, and do it more intense to make for the lack of time,” an online portal quoted celebrity trainer Andrea Orbeck as saying.
She is responsible for helping models Heidi Klum, Kimora Lee Simmons and Adriana Lima quickly getting back into shape.
Alcohol has different effects on men and women as gender influences which emotions drive heavy drinkers to drink, and how they feel the next day, a new study has found.
For men, anger drove drinking. A man who felt angry was more likely to drink the next day than a man who didn`t feel as enraged, researchers said.
They found that neither happiness, nor sadness had particular sway as a trigger for drinking in one gender over the other.
Researchers also said that neither of the genders who drink heavily effectively drown their sorrows with alcohol.
Skipping breakfast may help you loose weight in a healthy way, a new study has revealed.
Researchers at Cornell University conducted two experiments on about 25 participants who routinely ate or skipped breakfast to see how either habit would affect weight gain.
In the first experiment, researchers gave participants either no breakfast, a 335-calorie breakfast high in carbohydrates or a high fibre breakfast measuring 360 calories.
Researchers have made a breakthrough, which could help explain why women tend to accumulate fat in the stereotypical ‘pear’ shape, with more fat stored in the buttocks and thighs, and men in ‘apple’ shape, with more fat around the belly.
Gathering clues to answer these questions, Kathleen M. Gavin and her colleagues at East Carolina University examined how estrogen locally affects fat accumulation in these key areas by slowly infusing the hormone into the buttocks and belly in overweight women while also giving them drugs or having them exercise to speed up fat breakdown.
When it comes to enamel erosion of your teeth, diet soda is no better than regular ones, a new study has found.
In the last 25 years, Kim McFarland, D.D.S., associate professor in the University of Nebraska Medical Center College of Dentistry in Lincoln, has seen an increase in the number of dental patients with erosion of the tooth enamel – the protective layer of the tooth.
Once erosion occurs, it can’t be reversed and affects people their whole life.
A study has suggested having two to four cups of coffee every day can reduce the risk of suicide among men and women by 50 per cent.
The finding was reached after researchers from the Harvard School of Public Health reviewed data from three previous US studies.
They found that the risk of suicide amongst adults, drinking several cups of caffeinated coffee on a daily basis, was about half compared to those who drank decaffeinated coffee, very little coffee or no coffee at all, Daily Mail reported.
Women are not the only ones who have to worry about their reproductive clock, new research has showed that the quality of men’s sperm starts deteriorating after the age of 35.
The research also found that the X chromosome carrier sperms also seem to be on a rise, which means that the older dads have more chances of fathering a girl.
Bronte Stone at Reproductive Technology Laboratories in Los Angeles and his team tested sperm quality in samples from 5081 men in the age group of 16 and 72.
Daily dietary supplementation with a unique combination of omega fatty acids for six months could improve optical irritation symptoms and halt the progression of inflammation that characterizes moderate to severe dry eye, a new study has found.
The multicenter, double-blind, randomized, placebo-controlled clinical trial conducted at Baylor College of Medicine and Virginia Eye Consultants evaluated 38 post-menopausal women with tear dysfunction in both eyes.
A group of drug used to combat low blood pressure can help slow the rate of cognitive decline typical of dementia, a research has suggested.
According to research, these drugs, known as ACE inhibitors, could even boost brain power.
The researchers compared the rates of cognitive decline in 361 patients who had either been diagnosed with Alzheimer”s disease, vascular dementia, or a mix of both.
Eighty five of the patients were already taking ACE inhibitors; the rest were not.
A new study suggests that avoiding temptation may increase your chances of success if you are planning to lose weight or save for the future, than just relying on willpower alone.
The researchers compared the effectiveness of willpower versus voluntarily restricting access to temptations, called ‘precommitment’.
Examples of precommitment include avoiding purchasing unhealthy food and putting money in savings accounts with hefty withdrawal fees.
Cancer patients and survivors who report feeling tired or sluggish, felt noticeably better after taking ginseng supplements for two months, a new study has found.
Lead author Debra Barton, from the Mayo Clinic in Rochester, Minnesota said that nearly all patients with cancer can suffer from fatigue at some point; either at diagnosis, during treatment and even after treatment, and (fatigue) can linger for several years.
An unhealthy lifestyle characterised by physical inactivity, unhealthy diet, and smoking, is associated with a greater hazard of disability in individuals more than 65 years old, and the risk increases progressively with each additional unhealthy behaviour, according to a new study.
For instance, the risk of obesity, diabetes, cancer, poor cognitive function, stroke, sudden cardiac death and mortality increases with the number of unhealthy behaviours.
