Combination antiretroviral therapy helps treat HCV in patients co-infected with HIV Posted: 23 Jul 2014 11:17 AM PDT Treatment of HIV patients co-infected with the hepatitis C virus (HCV) with an anti-retroviral drug therapy not only tackles HIV, but also reduces HCV replication, according to a new study.

Age of puberty in girls influenced by which parent 'imprinted' genes are inherited from Posted: 23 Jul 2014 10:14 AM PDT The age at which girls reach sexual maturity is influenced by 'imprinted' genes, a small sub-set of genes whose activity differs depending on which parent passes on that gene, according to new research.

Genetics of cancer: Non-coding DNA can finally be decoded Posted: 23 Jul 2014 10:14 AM PDT Cancer is a disease of the genome resulting from a combination of genetic modifications, or mutations. We inherit from our parents strong or weak predispositions to developing certain kinds of cancer; in addition, we also accumulate new mutations in our cells throughout our lifetime. Although the genetic origins of cancers have been studied for a long time, researchers were not able to measure the role of non-coding regions of the genome until now.

How stress hormones promote brain's building of negative memories Posted: 23 Jul 2014 10:12 AM PDT Scientists have discovered a key component to better understanding how traumatic memories may be strengthened in women. Their study's findings suggest that developing clinical treatments that could lower norepinephrine levels immediately following a traumatic event might offer a way to prevent this memory-enhancing mechanism from occurring.

Physicians seeing increase in brown recluse spider bites Posted: 23 Jul 2014 10:12 AM PDT Medical toxicologists are reporting an increase in patients seen with brown recluse spider bites this summer. There are two components to spider bites -- the cutaneous lesion and, more rarely, the systemic symptoms that can occur following the bite.

Strategy proposed for preventing diseases of aging Posted: 23 Jul 2014 10:12 AM PDT Researchers argue that medicine focuses too much on fighting diseases individually instead of concentrating on interventions that prevent multiple chronic diseases and extend healthy lifespan. They call for moving forward with strategies that have been shown to delay aging in animals. In addition to promoting a healthy diet and regular exercise, these strategies include manipulating molecular pathways that slow aging and promote healthy longevity.

Wide-faced men negotiate nearly $2,200 larger signing bonus Posted: 23 Jul 2014 09:39 AM PDT Having a wider face helps men when they negotiate for themselves but hurts them when they are negotiating in a situation that requires compromise. Additionally, men who are more attractive are better collaborators compared to less attractive men.

Ancient genetic material from caries bacterium obtained for the first time Posted: 23 Jul 2014 08:04 AM PDT Streptococcus mutans, one of the principal bacteria that cause dental caries, has increased the change in its genetic material over time, possibly coinciding with dietary change linked to the expansion of humanity.

Life expectancy gains threatened as more older Americans suffer from multiple medical conditions Posted: 23 Jul 2014 07:59 AM PDT With nearly four in five older Americans living with multiple chronic medical conditions, a new study finds that the more ailments you have after retirement age, the shorter your life expectancy. The analysis, one of the first to examine the burden of multiple chronic conditions on life expectancy among the elderly, may help explain why increases in life expectancy among older Americans are slowing.

The 92 percent clean plate club: You're not alone in eating everything on your plate Posted: 22 Jul 2014 01:44 PM PDT If you're a member of the Clean Plate Club -- you eat pretty much everything you put on your plate -- you're not alone! A new study shows that the average adult eats 92 percent of whatever he or she puts on his or her plate. "If you put it on your plate, it's going into your stomach," says the author of the forthcoming book on the subject.

Dopamine transporter: Stampede supercomputer used to study common link between addiction, neurological disease Posted: 22 Jul 2014 01:43 PM PDT The XSEDE-allocated Stampede supercomputer has been used to study the dopamine transporter. Stampede is ranked seventh on the Top 500 list of supercomputers. Its research links altered dopamine signaling and dopamine transporter function to neurological and psychiatric diseases including early-onset Parkinsonism, ADHD, and cocaine addiction.

Presence of uterine cancers at time of hysterectomy studied using morcellation Posted: 22 Jul 2014 01:43 PM PDT Among women undergoing a minimally invasive hysterectomy using electric power morcellation, uterine cancers were present in 27 per 10,000 women at the time of the procedure, according to a study. There has been concern that this procedure, in which the uterus is fragmented into smaller pieces, may result in the spread of undetected malignancies.

Lacking trust in one's doctor affects health of emotionally vulnerable cancer patients Posted: 22 Jul 2014 01:41 PM PDT The physical and mental well-being of people with cancer may be affected by how they feel about their relationship with their physician and by differences in attachment styles, finds a new study. Patients who feel anxious and uneasy with their doctor may be impacted the most. "Anxiously attached patients may experience and report more physical and emotional problems when the relationship with their physician is perceived as less trusting," said the lead author.

New knee implant saves the ligaments Posted: 22 Jul 2014 01:41 PM PDT A new total knee replacement that saves all of the ligaments can make a person's knee feel and move just like the original. During a traditional total knee replacement, the surgeon must remove the "island" of bone to which the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are attached. The new knee features a shape that protects that island of bone and saves the ligaments.

Vaccine for dust-mite allergies created Posted: 22 Jul 2014 01:41 PM PDT A vaccine for dust-mite allergies has been created, researchers report. In lab tests and animal trials, the nano-sized vaccine package was readily absorbed by immune cells and dramatically lowered allergic responses. "What is new about this is we have developed a vaccine against dust-mite allergens that hasn't been used before," says a corresponding author on the paper.

Potential genetic link between epilepsy, neurodegenerative disorders Posted: 22 Jul 2014 01:41 PM PDT A potential link between epilepsy and neurodegenerative disorders has been uncovered by new research. "This is, to our knowledge, the first direct genetic evidence demonstrating that mutations in the fly version of a known human epilepsy gene produce seizures through altered vesicle transport," says the senior author of the study.

Gene variant identified as heart disease risk factor for women Posted: 22 Jul 2014 12:25 PM PDT A genetic basis has been identified for heart disease in women. This new information helps to identify which women are more prone to heart disease, researchers report. The gene, when functioning normally, is activated in part by the hormone estrogen and has been previously shown to relax the blood vessels, and in turn, lower blood pressure.

Forty-five percent rise in diagnostic imaging tests by GPs in Australia Posted: 22 Jul 2014 12:25 PM PDT A 45 percent rise in diagnostic imaging tests ordered by Australian GPs is being driven by increasing GP visits, a rising number of problems managed at consultations and a higher likelihood that GPs order imaging tests for these problems, according to a new study says. Based on a long term national survey of 9,802 GPs between 2002 and 2012, the report draws on data from more than 980,000 GP-patient encounter records to assess the extent to which GP's order tests in line with diagnostic imaging guidelines.

Distinctive developmental origin for a drainage tube in the eye Posted: 22 Jul 2014 11:25 AM PDT Scientists have conducted a comprehensive exploration of an eye structure known as Schlemm's canal: a key gatekeeper for the proper flow of eye fluid, presenting a number of insights relevant to glaucoma and other diseases.

Death of a parent during childhood is associated with greater mortality in early adulthood Posted: 22 Jul 2014 11:25 AM PDT Experiencing the loss of a parent during childhood or adolescence is associated with a greater risk of mortality, according to a new study. Individuals who lost either a mother or a father during childhood had a greater risk of mortality in the years following the parent's death compared with people unaffected by parental death during childhood.

Pathogenic connection between autoimmune disorders, cancer found Posted: 22 Jul 2014 11:24 AM PDT Autoimmune disorders may share certain pathogenic mechanisms with cancer, according to a new report. "This study opens a new therapeutic approach for myasthenia gravis, as well as other autoimmune disorders," said one researcher. "Conventional therapies may improve the disease, but have numerous complications. This discovery may lead to a viable treatment option for the millions of American suffering from these disorders."

Clients of violence interventional advocacy program find experience supportive Posted: 22 Jul 2014 10:07 AM PDT Participants who received care through a Violence Intervention Advocacy Program -- an interventional program targeting the physical, mental, emotional and social needs of violently injured youths -- were less likely to retaliate for their injuries and experienced life changing behaviors through connections to caring, steady, supportive adults who helped them feel trust and hope, researchers report.

Retail pricing strategies: Do consumers prefer Deep Discounts or Everyday Low Prices? Posted: 22 Jul 2014 09:57 AM PDT Sometimes finding the best bang for your buck feels like a wild goose chase. It's hard to know which stores offer the best prices at any given time. According to a new study, when trying to maximize savings, consumers will choose retailers they believe offer the lowest prices the majority of the time.

I’ll have what he's having? How consumers make choices about new products Posted: 22 Jul 2014 09:57 AM PDT Have you found yourself at a fancy restaurant trying to impress new friends or in a foreign country and unsure of what to order? Not wanting to appear foolish, you just go along with everyone else. According to a new study, we're more likely to copy other people's choices when we lack social acceptance or enough information to make an informed decision.

Empathy or justice: What makes consumers donate more to charity? Posted: 22 Jul 2014 09:57 AM PDT Have you ever received a request for help and wondered how deserving the recipients are of your donation? This way of thinking may seem inconsistent with your moral values, especially if you consider yourself an otherwise compassionate and empathic person. A new study suggests that moral identity decreases donations when recipients are deemed to be responsible for their plight.

Why do challenging tasks make consumers believe drugs wear off faster? Posted: 22 Jul 2014 09:57 AM PDT Imagine that you have a cup of coffee and sit down to read People magazine. How long do you think the energy boost will last before you reach for another cup? Would you need more caffeine if you tried to read War and Peace? A new study finds that consumers wrongly believe that pharmacological products such as coffee and aspirin lose their effectiveness when they engage in more strenuous activities.
