Washington, Nov 9 - A new study has allowed researchers better understanding of how antidepressants work in the human brain - and may lead to the better antidepressants' development with few or no side effects.
The article from Eric Gouaux, Ph. D., a senior scientist at OHSU 's Vollum Institute and a Howard Hughes Medical Institute Investigator describes research that gives a better view of the structural biology of a protein that controls communication between nerve cells.
The article focuses on the structure of the dopamine transporter, which helps regulate dopamine levels in the brain.
Washington, Nov. 9 - Scientists have found an enzyme, Wip1 phosphatase, as a potential target to stop the progression of cancer.
Although studies in the past have revealed that this enzyme plays a critical role in regulating the budding of tumours, scientists have for the first time unearthed a mechanism for its mode of action.
Dr Dmitry Bulavin and his team at A*STAR's Institute of Molecular and Cell Biology (IMCB), discovered that Wip1 phosphatase is a key factor that causes point mutations to sprout in human cancers.
Washington, Nov 8 - A new study has found that consumption of nuts, including tree nuts (such as almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts), is inversely associated with risk of pancreatic cancer, independent of other potential risk factors for pancreatic cancer.
Researchers looked at the association between nut consumption and risk of pancreatic cancer among 75,680 women in the Nurses' Health Study, with no previous history of cancer.
Washington, Nov 7 - Researchers have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defence systems.
The new study shows how 'uncloaking' the virus using an experimental drug triggers an immune response that stops the virus from replicating in cells grown in the laboratory. The findings could lead to new treatments and help to improve existing therapies for HIV infection.
Washington, Nov. 7 - A new research has showed that tea could help lose weight, improve heart health and slow prostate cancer's progression.
The December 2013 issue of the American Journal of Clinical Nutrition features 12 new articles about the relationship between tea and human health.
Highlights of some of the compelling reports published through the AJCN include the following five papers:
Tea leaf polyphenols may promote weight loss
Tea polyphenols and the caffeine content in tea increase energy expenditure and fat oxidation, providing benefits for achieving and maintaining an ideal body weight.
Tea may reduce risk for some cancers
Washington, Nov 7 - A new study has proposed that protein called insulin-like growth factor (IGF), which is delivered via breastfeeding, could help predict an infant's propensity to later develop autism.
The study by Touro researcher, Gary Steinman, points to numerous prior studies that powerfully link IGF with a number of growth and neural functions.
Steinman further pointed to breastfeeding as a relatively abundant source of the protein. He says that IGF delivered via breastfeeding would compensate for any inborn deficiency of the growth factor in newborns.
Washington, Nov 6 - Researchers have shown how Web-based, at-home interventions can help mothers address behaviors known to protect against childhood obesity.
Adam Knowlden, a former doctoral student at University of Cincinnati and current assistant professor in the University of Alabama's Health Science Department, hopes his research can better prepare moms to keep their kids from joining the rising ranks of America's obese children.
"Addressing this problem of childhood obesity needs to start in the home environment and preferably with children at younger ages," Knowlden said.
Washington, Nov 5 - A team of researchers has warned governments and healthcare decision makers across the globe to be wary of the myths and hype that currently surround medical tourism.
'Medical tourism' is where people leave their own country to seek medical treatment abroad. They are typically treated as private patients and the costs are fully recouped. This is distinct from 'health tourism' where there is not always an intention to pay.
Washington, Sep 11 - An Indian campaigner wants the US government ban Internet companies like Google from advertising and legitimising new technologies of sex selection in India.
"Sex selection tourism is worse than trafficking," Sabu M George, a member of India's Campaign Against Sex Selection, told a House panel Tuesday accusing Google of "carrying advertisements targeting the privileged Indians for sex selection to Dubai, Thailand, US, and Europe."
Washington, Aug 5 - A two-year-old boy in the US, who is suffering from a type of blood cancer and who doctors say may only live for a few weeks, has served as the best man at his parents' wedding.
Logan Stevenson has acute myeloid leukaemia and has undergone several operations. Last month, doctors said he had only weeks left to live, BBC reported.
This diagnosis prompted Logan's parents, Christine Swidorsky and Sean Stevenson, to bring forward the wedding they had originally planned for July 2014. The wedding was held in Pittsburgh.
Washington, July 26 - With heart disease emerging as the number one killer among Indians, an ethnic doctors' group has launched educational "Networks" to foster high quality medical education of Asian Indian origin physicians in the US.
Launched by the influential American Association of Physicians of Indian Origin (AAPI), these networks are made up of noted physicians in the areas of cardiology, diabetes, and stroke from Harvard, Mayo Clinic, and Cleveland Clinic.
Los Angeles, July 4 - A recent study has found that curcumin, a constituent of turmeric, can provide protection against lung damage in infants.
Premature infants often need the assistance of ventilator and forced oxygen therapy because they're frequently born with inadequate lung function. These therapies can cause lasting lung damage and even death among infants.
Researchers at Los Angeles Biomedical Research Institute at Harbor-University of California-Los Angeles Medical Center (LA BioMed), using disease models, found that curcumin provided long-term protection against this damage.
Los Angeles, June 6 - The enormous benefits that regular practice of yoga yields in increasing the flexibility of the body is well known. Researchers now show that a 20-minute session of yoga significantly boosts brain activity immediately afterwards.
A report in Science Daily showed that participants performed significantly better immediately after the yoga practice, than after moderate to vigorous aerobic exercise for the same amount of time.
Florence, May 23 - A 68-year-old American tourist underwent emergency surgery to remove a kidney after he was stabbed in Italy's Florence city.
The tourist, who was not named, was attacked near the famous Duomo cathedral.
Doctors at the Santa Maria Nuova hospital said the man suffered knife wounds to a kidney and a lung but was no longer critical, and was conscious and breathing unaided.
Police arrested a 37-year-old homeless man from the southern city of Bari over the stabbing.
Police said the tourist was stabbed by the suspect as he tried to mug him while he and his wife were listening to a street musician. (IANS)
Washington, May 22 : Scientists have engineered nanoparticles derived from grapefruit lipids that could be used to deliver anti-cancer and other drugs to tumour cells, says a study.
Grapefruit has long been known for its health benefits, and the subtropical fruit may revolutionise how medical therapies like anti-cancer drugs are delivered to specific tumour cells, say researchers.
The University of Louisville researchers have uncovered how to create nanoparticles using natural lipids derived from grapefruit, and have discovered how to use them as drug delivery vehicles, reports Science Daily.
