Medicine & Health news

Scientists observe altruism and selfishness in brain activity

Prosocial behavior is fundamental to the sustainability of society, enabling people to work in groups, to create larger and more successful social structures, and to contribute to the common welfare. However, despite the importance of altruism, science has only a limited understanding of how prosocial behaviors and selfish behaviors are represented in the brain. Additionally, individual transition between self-benefiting behavior and altruistic behavior is not well understood.

Setting the circadian clock

Often referred to as the "body clock", circadian rhythm controls what time of day people are most alert, hungry, tired or physically primed due to a complex biological process that is not unique to humans. Circadian rhythms, which oscillate over a roughly 24-hour cycle in adaptation to the Earth's rotation, have been observed in most of the planet's plants, animals, fungi and cyanobacteria, and are responsible for regulating many aspects of organisms' physiological, behavioral and metabolic functions.

New research could lead to pharmacological treatments for chronic pancreatitis

The pancreas is a tricky organ for researchers and surgeons alike because of its sensitivity. Tucked away in a hard-to-reach spot behind the stomach, it's in charge of secreting enzymes to help digest everything you eat. Even slightly puncturing the pancreas during surgery can cause it to begin digesting itself.

Mini-breast grown in Petri dishes—a new tool for cancer research

The research group, led by Dr. Christina Scheel, developed an assay whereby cultured human breast epithelial cells rebuild the three-dimensional tissue architecture of the mammary gland. For this purpose, a transparent gel is used in which cells divide and spread, similar to the developing mammary gland during puberty. Specifically, cells divide and generate hollow ducts that form a network of branches and terminate in grape-like structures. Throughout the reproductive lifespan of a woman, the mammary gland is constantly remodeled and renewed in order to guarantee milk production even after multiple pregnancies. Although their exact identity remains elusive, this high cellular turnover requires the presence of cells with regenerative capacity, i.e. stem cells. Breast cancer cells can adopt properties of stem cells to acquire aggressive traits. To determine how aggressive traits arise in breast cancer cells, it is therefore crucial! to first elucidate the functioning of normal breast stem cells. For this purpose, the Scheel group provides a new powerful experimental tool.

Why obesity predisposes to severe respiratory failure

The lungs of seven percent of all intensive care unit patients will fill up with fluid causing a 30 to 50 percent chance of death from a condition called acute respiratory distress syndrome (ARDS). This syndrome has few options for treatment, progresses quickly and is still poorly understood biologically, and being obese is an important risk factor. Using animal models of ARDS, researchers at Thomas Jefferson University in Philadelphia have uncovered a mechanism that appears to explain why obesity predisposes to developing ARDS, and in the process, might have discovered a novel strategy for preventing ARDS in obese individuals.

Mechanism regulating gene expression linked to bone and joint damage in AS

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference revealed that DNA methylation - a mechanism that regulates gene expression - could influence the progression of structural damage to the joints and spine in ankylosing spondylitis (AS). Study findings showed significant associations between a low methylation score and more radiographic progression (X-ray) of the disease, and implicated smoking in worsening of disease outcome.

Early RA patients have impaired myocardial & vascular function at early stage of disease

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) demonstrated for the first time that treatment-naive patients with early Rheumatoid Arthritis (RA) have myocardial and vascular abnormalities, even at the earliest stage of their disease. These findings suggest that patients may develop early cardiomyopathy (disease of the heart muscle), increasing their risk of cardiovascular morbidity and mortality from the time of their diagnosis. Cardiomyopathy is a serious condition and a leading cause of hospitalisation worldwide.

Inspiratory muscle training improves lung function in ankylosing spondylitis

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) showed that inspiratory muscle training (IMT) significantly improves lung strength and efficiency in patients with ankylosing spondylitis (AS), a condition often associated with breathing difficulties. These findings demonstrate that just eight weeks of IMT provide greater improvements in lung function than conventional treatment options.

Hepatitis B vaccine less effective in rheumatoid arthritis patients

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference showed that people with rheumatoid arthritis (RA) are less likely to be protected by hepatitis B vaccination than the general population. Within the trial only 11% of those with the condition responded to the vaccine, compared with 83% of those without RA, suggesting that people with RA may still be at risk of infection in spite of vaccination.

Validated measurements of fatigue should be used to optimize its treatment in RA

Three new studies presented at the European League Against Rheumatism Annual Congress (EULAR 2015) have provided valuable guidance on measuring fatigue and optimising its treatment in Rheumatoid Arthritis (RA) patients, and in patients with other rheumatic diseases. Fatigue remains a frequent and debilitating problem for patients with RA that needs to be addressed.

Novel method identifies children with rheumatic disease eligible for life-saving vaccine

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference showed that the chickenpox (varicella) vaccine can be effective and safe even in children with paediatric rheumatic disease receiving immunosuppression treatment. By using a checklist to pre-screen children, the investigators were able to identify diverse patient groups suitable for vaccination, protecting them from a potentially life-threatening infection.

New treatment approach to limit damage after joint bleed

The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) identified that the cytokine (cell signalling protein) Interleukin-1β (IL-1β) is a crucial factor in the development of blood-induced cartilage damage. This finding opens up the possibility that a treatment targeting IL-1β could provide a new way to protect cartilage after a joint bleed, which in turn should significantly reduce subsequent disability.1

Helicobacter pylori causes gene activity in the gastric cells resembling the activity of cancer cells

Around half of the global population is chronically infected with the stomach bacterium Helicobacter pylori, almost 1% of whom go on to develop gastric adenocarcinoma, one of the deadliest forms of cancer. Usually it takes many decades for the cancer to develop, making it difficult to pinpoint exactly how it is linked to an infection. A team at the Max Planck Institute for Infection Biology in Berlin, Germany, has now analyzed the pattern of damage that occurs in the genome of gastric cells early after infection and found that not only does this pattern differ from those induced by other genotoxic agents, but that it resembles the characteristic changes later seen in gastric cancer. While it has been widely accepted that this pathogen plays a role in the development of gastric cancer, these results represent an approach that can reveal a causality between a particular bacterial infection and the development of cancer in humans.

The study, "Look at the gato! Code-switching in speech to toddlers" appears in the Journal of Child Language. 

Study may help Department of Veteran's Affairs find patients with high risk of suicide

Clinicians are challenged every day to make difficult decisions regarding patients' suicide risk. Using Veterans Health Administration (VHA) health system electronic medical record data, Veterans Affairs (VA) and National Institute of Mental Health (NIMH) scientists were able to identify very small groups of individuals within the VHA's patient population with very high, predicted suicide risk—most of whom had not been identified for suicide risk by clinicians. Such methods can help the VHA to target suicide prevention efforts for patients at high risk, and may have more wide-ranging benefits.

Dogs are able to follow human gaze

Dogs are known to be excellent readers of human body language in multiple situations. Surprisingly, however, scientists have so far found that dogs do not follow human gaze into distant space. Scientists at the Messerli Research Institute at the Vetmeduni Vienna investigated how this skill of dogs is influenced by aging, habituation and formal training. The outcome: Gaze following to human gaze cues did not differ over the dogs' lifespan, however, formal training was found to directly influence gaze following in dogs. The results were published in the journal Animal Behaviour.

Goldfields ant nests under surveillance for elusive butterfly

The ocean's internet fits on a transmitter smaller than a USB

A new paper, published in Science, details the explosion in aquatic animal tracking research over the past 30 years and its impact on discoveries about the movements, migrations, interactions and survival of both common and elusive aquatic species.

Dragonfly watch – find those fast and furious insects

"I'm an aquatic entomologist, and dragonflies and damselflies are the most colorful and noticeable insects in the habitats in which I work," says Dr. Celeste A. Searles Mazzacano, a staff scientist and Aquatic Conservation Director at the Xerces Society. In her role as the project coordinator for the Migratory Dragonfly Partnership, she continues to add acclaim to these fast and furious little critters, "The nymphs are amazing predators with extremely cool adaptations for feeding—hinge-toothed lower lips that shoot out faster than the eye can see—and respiration rectal gills that double as a jet-propulsion chamber!"
