Is Technology Making Us Healthier Or More Sick?
Date: Jan-18-2013Is technology actually good for us? The question of whether technology is going to make us healthier or more sick was recently explored by the global intelligence unit of McCann Erickson. The agency released results from their study called "The Truth About Wellness" which questioned over 7,000 people from several different countries around the world about their opinion on technology's effects. Whilst a little over half of the respondents believe that technology is indeed making us healthier, a surprising 46% think that it is not helping us at all and only making us more sick...
Potential Uses For 'Superomniphobic' Surfaces Include Protective Wear; Surfaces That Shrug Off Microbes Like Bacteria
Date: Jan-18-2013In an advance toward stain-proof, spill-proof clothing, protective garments and other products that shrug off virtually every liquid - from blood and ketchup to concentrated acids - scientists are reporting development of new "superomniphobic" surfaces. Their report on surfaces that display extreme repellency to two families of liquids - Newtonian and non-Newtonian liquids - appears in the Journal of the American Chemical Society...
Tanning Bed Cancer Risk Double That Of Summer Sun
Date: Jan-18-2013The risk of skin cancer from tanning beds is two times higher than spending the same length of time in the Mediterranean midday summer sun. The finding came from a new study conducted by a team of researchers at the University of Dundee, Scotland, and published in the British Journal of Dermatology. The scientists examined 400 tanning beds in the UK and measured their levels of ultraviolet (UV) radiation. UV radiation was emitted at levels above British and EU guidelines in nine out of ten beds...
Mothers Of Newborns In Neonatal Intensive Care Units Concerned About Privacy And Comfort When Expressing Breast Milk
Date: Jan-18-2013Many mothers of newborns in neonatal intensive care units have difficulty finding private, quiet places in the hospital to express milk, according to a new study from the Frances Payne Bolton School of Nursing at Case Western Reserve University. The lack of privacy - if it causes mothers to miss feedings or makes them too timid to express milk - is an even greater health risk for low-weight premature newborns, because milk enriched with the mother's antibodies helps ward off infection and gastrointestinal problems. "The meaning of privacy might differ for mothers and the hospital...
First Successful Practical Synthesis Of Large Amounts Of Promising Anti-Cancer Substance
Date: Jan-18-2013Scientists are reporting development of the first practical way to make large amounts of a promising new anti-cancer substance that kills cancer cells differently than existing medicines. Their article on synthesis of the substance, and tests demonstrating its effectiveness in the laboratory, appears in ACS' Journal of Medicinal Chemistry. Isamu Shiina and colleagues explain that the substance, AMF-26, showed promise against certain forms of cancer in laboratory studies, fostering excitement about its potential for development as a new anti-cancer drug...
HIV Patients May Benefit From Probiotics
Date: Jan-18-2013Antiretroviral (ARV) drugs are the first line therapy for patients with HIV; however, ARV-treated, HIV-infected individuals still have a higher mortality rate than uninfected individuals. During the course of infection, HIV patients develop inflammation that damages the walls of the intestines, known as the gut mucosa, allowing intestinal microbes to escape and enter the blood stream to cause a life-threatening systemic infection...
Viruses Prompt Oncogenic Transformation By Genetically Altering Infected Cells As Seen In Hepatitis B
Date: Jan-18-2013Several recent studies have demonstrated that viruses alter the expression of microRNAs, non-coding RNA molecules that can block the expression of target genes. In this issue of the Journal of Clinical Investigation, Xiaoje Xu and colleagues at the Beijing Institute of Biotechnology report that miR-148a is repressed by hepatitis B virus (HBV) X protein (HBx) to promote growth and metastasis of liver cancer...
People's Preferences For The Height Of A Partner Persist Despite Other Factors Important In Choosing A Mate
Date: Jan-18-2013Finding Mr. or Ms. Right is a complicated process, and choosing a mate may involve compromising on less important factors like their height. However, research published in the open access journal PLOS ONE by Gert Stulp and colleagues from the University of Groningen, Netherlands suggests that despite the many other factors involved, people's preferences for a partner's height are reflected in real couples in the UK. Given the average heights of men and women in typical Western populations, two out of every hundred couples should comprise a woman who is taller than her male companion...
Invading Malaria Parasites Trapped Inside Host Cell: Basis For New Drugs?
Date: Jan-18-2013One of the most insidious ways that parasitic diseases such as malaria and toxoplasmosis wreak their havoc is by hijacking their host's natural cellular processes, turning self against self. Researchers from the Perelman School of Medicine, University of Pennsylvania and Johns Hopkins University, led by Doron Greenbaum, Ph.D., assistant professor of Pharmacology at Penn, have identified the cell signaling pathway used by these parasites to escape from and destroy their host cells and infect new cells - pointing the way toward possible new strategies to stop these diseases in their tracks...
Simple Blood Test Reveals DNA Marker That Predicts Breast Cancer Recurrence
Date: Jan-18-2013Medical researchers at the University of Alberta tested the DNA of more than 300 women in Alberta and discovered a 'genetic marker' method to help accurately profile which women were more apt to have their breast cancer return years later. Sambasivarao Damaraju, a professor with the Faculty of Medicine & Dentistry, and at the Cross Cancer Institute just published his team's findings in the peer-reviewed journal, PLoS One...
