Washington, August 28 : Cedars-Sinai researchers have found that a common vitamin may have the potential to fight certain “superbugs,” antibiotic-resistant staph infections that health experts see as a threat to public health.
Washington, August 28 : Some types of fats have been linked to ailments like heart disease and diabetes, while others, like those often found in plants and fish, have well documented health benefits.
So why do our bodies respond so destructively to some fats but not others?
The answer may lie in how different fats interact with the microbes in our guts, according to researchers from the University of New Mexico and Northwestern University.
Washington, August 28 : More than 40 plant-based compounds can turn on genes that slow the spread of cancer, according to a first-of-its-kind study by a Washington State University researcher.
Gary Meadows, WSU professor and associate dean for graduate education and scholarship in the College of Pharmacy, said he is encouraged by his findings because the spread of cancer is most often what makes the disease fatal.
Washington, Aug 28 - A common vitamin may potentially provide a powerful tool to fight 'superbugs', antibiotic-resistant staphylococcus infections that health experts view as a threat to public health.
Washington, Aug 28 - A unique property in breast milk promotes gut bugs that give infants greater immunity from infections than any infant formula, according to a US study.
"This study provides insight to the mechanisms underlying the benefits of breast feeding over formula feeding for newborns," said William Parker, associate professor of surgery at Duke University Medical Centre and senior study author.
Washington, August 28 : Reducing television-viewing duration may be an effective strategy to prevent excess weight gain in adolescent kids, a new study has revealed.
The findings were based on a one-year community-based randomised trial that included 153 adults and 72 adolescents from the same households.
Washington, August 28 : Renal denervation has been found to be effective in treating patients with resistant hypertension, a condition that greatly increases the risk of myocardial infarction and stroke.
Resistant hypertension puts approximately 120 million people worldwide at risk of premature death from kidney disease and cardiovascular events such as stroke, heart attack and heart failure.
Washington, August 28 : Energy drinks can exert acute positive benefits on heart performance, a new study has revealed.
The current study, led by Dr Matteo Cameli from University of Siena, which used avant-garde technique in echocardiography and echo Doppler analysis to explore the influence of energy drinks on heart function on 35 healthy subjects, found that their ventricular functions were better and enhanced.
Washington, August 28 : Insufficient sleep is linked to more aggressive form of breast cancers and the likelihood of its recurrence, a study has revealed.
The study, led by Cheryl Thompson, Assistant Professor at Case Western Reserve University School of Medicine, analysed medical records and survey responses from 412 post-menopausal breast cancer patients with Oncotype DX.
Washington, Aug 28 - Super cooling coal smoke would slash emission of carbon dioxide (CO2) and dangerous chemicals by more than 90 percent, according to a simple math-driven formula designed by a team of physicists.
Washington, Aug 28 - Dependency on marijuana before 18 years of age may cause lasting damage to the addict's intelligence, attention and memory, according to an international research.
A long-range study of more than 1,000 New Zealanders, individuals who started using cannabis in adolescence and used it for years afterward, showed an average decline in IQ of eight points when their age 13 and age 38 IQ tests were compared.
Washington, Aug 26 - Alzheimer's hits women more severely than men, even when both are in the same stage of the disease.
Researchers from the University of Hertfordshire discovered that men with Alzheimer's consistently performed better than their women counterparts, across the five cognitive areas they examined.
Washington, Aug 26 - Human lungs rely on sticky mucus to expel foreign matter, including toxic and infectious agents during a cold or an allergy that causes a running nose and a wet cough, says a study.
The study by Brian Button and colleagues from the University of North Carolina, Chapel Hill, helps to explain how human airways clear such mucus out of the lungs.
Washington, August 24 : Northwestern University scientists have discovered one of the ways the influenza virus disarms our natural defense system.
The virus decreases the production of key immune system-regulating proteins in human cells that help fight the invader. The virus does this by turning on the microRNAs -- little snippets of RNA -- that regulate these proteins.
Washington, August 24 : A nanoparticle developed at Rice University and tested in collaboration with Baylor College of Medicine (BCM) might aid emergency care of traumatic brain-injury victims, even those with mild injuries.
Washington, Aug 24 : Scientists can now choke tumours by cutting off the supply of a specific sugar known as GlcNAc (glick-nack), which they have identified for the first time.
Tumours need abundant supplies of cellular building blocks, specifically amino acids and nucleotides (a compound), to keep multiplying fast under harsh conditions, the journal Science reported.
Washington, Aug 24 - A new type of bio-sensor can detect minute traces of glucose in saliva, tears and urine, doing away with pinpricks for diabetes testing.
"It's an inherently non-invasive way to estimate glucose content in the body," said Jonathan Claussen, former Purdue University doctoral student and now a research scientist at the US Naval Research Lab.
Washington, August 23 : UC Irvine microbiologists have found a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold by discovering how certain viruses use their host cells to replicate.
Washington, August 23 : Scientists have identified a substance in smokeless tobacco that is a strong oral carcinogen, a health risk for the 9 million users of chewing tobacco, snuff and related products.
They have also called upon the federal government to regulate or ban the substance.
"This is the first example of a strong oral cavity carcinogen that's in smokeless tobacco," said Stephen Hecht, Ph. D., who led the study.
Washington, Aug 23 - A mother's emotional health and education level during her child's earliest years influence oral health at age 14, says a new study.
Researchers at the Case Western Reserve University, US, started with the oral health of the teenagers and worked backwards to age three to find out what factors in their past influenced their oral health outcomes.
Washington, August 23 : In a new study, researchers have tried to shed light on alcohol-related birth defects.
The project, which is a collaborative effort by scientists at the University of North Carolina School of Medicine, Duke University, and University College of London in the UK, led by Kathleen K. Sulik could help enhance how doctors diagnose birth defects caused by alcohol exposure in the womb.
Washington, August 22 : Young infants who are treated with antibiotics before 6 months are more likely at risk of being overweight in childhood, according to a study.
Washington, August 22 : Researchers have shown that people with Parkinson's disease performed markedly better on a test of working memory after a night's sleep, and sleep disorders can interfere with that benefit.
While the classic symptoms of Parkinson's disease include tremors and slow movements, Parkinson's can also affect someone's memory, including "working memory."
Washington, August 22 : Scientists hope that a powerful new anti-cancer drugs based on green tea could soon be developed after they found that an extract from the beverage could make almost half of tumours vanish.
The University of Strathclyde team made 40 per cent of human skin cancer tumours disappear using the compound, called epigallocatechin gallate, in a laboratory study.
