How can psychological stress be determined in chronic cardiovascular disease?
An investigation in one of the last issue of Psychotherapy and Psychosomatics addresses the evaluation of psychological stress in the setting of chronic cardiovascular disease. In a number of circumstances allostatic systems may either be overstimulated or not perform normally, and this condition has been termed 'allostatic load', or the price of adaptation. Findings from several studies suggest that it is associated with worse health conditions and plays a significant role in the susceptibility, course, and outcome of cardiovascular (CV) diseases. Recently, Fava and colleagues introduced clinimetric criteria for assessing allostatic overload syndrome (AOS) based on: (a) current identifiable sources of distress in the form of acute or chronic stress (the stressor is judged to tax or exceed the individual's coping skills when its full nature and circumstances are evaluated), and (b) psychiatric symptoms (DSM-IV) or psychosomatic symptoms (DCPR) or significant impairment in ! social or occupational functioning or in psychological well-being occurring within 6 months after the onset of the stressor.

Is surgery the only option for meniscal tear and osteoarthritis?
Many middle age and older adults have disabling knee pain due to a tear in the meniscus, an important supporting structure in the knee that is often damaged in patients with underlying knee osteoarthritis. In the United States, more than 450,000 arthroscopic meniscal surgeries are performed each year to treat meniscal tears. However, there is little data available to clinicians who must decide with their patients whether it is best to treat tears with surgery or with physical therapy. Now, new research from Brigham and Women's Hospital (BWH), suggests that physical therapy (PT) may prove just as effective as surgery for some patients. These findings are presented at the annual meeting of the American Academy of Orthopedic Surgeons and simultaneously published online in the New England Journal of Medicine.

A study published in the March issue of Hepatology, a journal of the American Association for the Study of Liver Diseases, estimates that the prevalence of acute hepatitis C virus (HCV) infection is nearly one percent among newly incarcerated inmates with a history of recent drug use. Findings suggest that systematic screening of intravenous (IV) drug users who are new to the prison system could identify more than 7,000 cases of HCV across the U.S. annually—even among asymptomatic inmates.
Sex between monogamous heterosexuals rarely source of hepatitis C infection
Individuals infected by the hepatitis C virus (HCV) have nothing to fear from sex in a monogamous, heterosexual relationship.

Research led by a biology professor in the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) has uncovered a method to produce retinal cells from regenerative human stem cells without the use of animal products, proteins or other foreign substances, which historically have limited the application of stem cells to treat disease and other human developmental disorders.
Mayo Clinic researchers develop test to gauge severity of concussions
Neurologists at Mayo Clinic in Arizona have taken a promising step toward identifying a test that helps support the diagnosis of concussion. Their research has shown that autonomic reflex testing, which measures involuntary changes in heart rate and blood pressure, consistently appear to demonstrate significant changes in those with concussion. They presented the findings at the American Academy of Neurology annual meeting in San Diego this week.
New study points to major discovery for Alzheimer's disease
The Journal of Neuroscience has published a study led by researchers at the Max Planck Florida Institute for Neuroscience, the first and only U.S. extension of the prestigious Max Planck Society, that may hold a stunning breakthrough in the fight to treat Alzheimer's disease. The study potentially identifies a cause of Alzheimer's disease—based on a newly-discovered signaling pathway in cellular models of Alzheimer's disease—and opens the door for new treatments by successfully blocking this pathway. The Institute, which recently opened in December 2012, focuses solely on basic neuroscience research that aims to analyze, map, and decode the human brain—the most important and least understood organ in the body.

Can a tropical water flea invade European lakes?
Daphnia is a genus of small, planktonic crustaceans, commonly called 'water fleas' because of their jumpy swimming style and their size (between 0.2 and 5 mm). They live in various aquatic environments, ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Species of the genus Daphnia play a key role in freshwater food webs: they consume algae and are themselves an important food item for small fish.
Research explores road signs on the intracellular highway
The interior of every cell within our bodies is crisscrossed with a network of molecular highways upon which nutrients, replacement parts, and other vital materials travel to their appropriate location. The system is immensely complex, and wrong turns are among the cellular malfunctions observed in connection with diseases like Alzheimer's, amyotrophic lateral sclerosis (ALS or Lou Gehrig's Disease), and polycystic kidney disease.

Why sea-faring mammals need to be larger than land lubbers
(Phys.org) —Ever notice you get cold faster when you're wet? That's why whales are so much bigger than elephants, according to SFI External Professor Aaron Clauset in a recent paper published in the journal PLoS One that examines what might have caused mammalian species to evolve to the sizes they did.
Risk management in fish: How cichlids prevent their young from being eaten
For a variety of reasons, many humans choose to adopt children. More surprisingly, adoption is fairly widespread in the animal kingdom, even though it would seem to counteract the basic premise of Darwin's theory of evolution, which suggests that animals should raise as many of their own offspring as possible. Understanding the rationale for adoption has challenged theorists for generations. Franziska Schaedelin and colleagues at the University of Veterinary Medicine, Vienna now describe a new approach to the problem. The scientists present findings that suggest parents of fish exchange young with other parents to reduce the chances that their entire brood will be predated. The results are published in the current issue of the journal Behavioral Ecology.
New fish test for virus is nonlethal
(Phys.org) —Cornell researchers have successfully identified the presence of a deadly virus—the viral hemorrhagic septicemia virus (VHSV)—by using techniques that are not lethal to fish.
Plant defenses: Maize knows how to identify its target
Insect or microbe: plants recognize their attackers and respond by producing specific internal signals that induce the appropriate chemical defenses. That is the main conclusion of a study at the Center for Medical, Agricultural and Veterinary Entomology operated at Gainesville, Florida (USA)* by USDA's Agricultural Research Service, to which the team around Prof. Ted Turlings of the University of Neuchâtel, Switzerland, has contributed. The study is published today in the prestigious journal PNAS.
How proteins read meta DNA code
Three-quarters of the DNA in evolved organisms is wrapped around proteins, forming the basic unit of DNA packaging called nucleosomes, like a thread around a spool. The problem lies in understanding how DNA can then be read by such proteins. Now, Arman Fathizadeh, a physicist at Sharif University of Technology in Tehran, Iran, and colleagues have created a model showing how proteins move along DNA, in a paper just published in European Physical Journal E.

Kill Bill character inspires the name of a new parasitoid wasp species
Parasitoid wasps of the family Braconidae are known for their deadly reproductive habits. Most of the representatives of this group have their eggs developing in other insects and their larvae, eventually killing the respective host, or in some cases immobilizing it or causing its sterility. Three new species of the parasitoid wasp genus Cystomastacoides, recently described in the Journal of Hymenoptera Research, reflect this fatal behavior.
