Identified brain circuitry bridges neural and behavioral roles in PTSD

Science Daily (US) - 22/06/2017
Specific cerebral circuitry bridges chemical changes deep in the brain and the more outward behavioral expressions associated with post-traumatic stress disorder (PTSD), which could lead to more objective biomarkers for the disorder, according to a comprehensive review of rapidly changing data.

First-line immunotherapy treatment can improve survival for subset of lung cancer patients

Science Daily (US) - 22/06/2017
Findings from a phase III clinical trial for advanced lung cancer patients could help oncologists better predict which patients are likely to receive the most benefit from immunotherapy as a first-line treatment based on the unique molecular characteristics of their tumor, according to a new study.

An end to population aging in China, Germany, USA

Science Daily (US) - 21/06/2017
New measures of aging, combined with UN population projections, show that population aging is likely to end before 2100 in China, Germany, and the USA.

Predicting cognitive deficits in people with Parkinson's disease

Science Daily (US) - 21/06/2017
Parkinson's disease is commonly thought of as a movement disorder, but after years of living with the disease, approximately 25 percent of patients also experience deficits in cognition that impair function. A newly developed research tool may help predict a patient's risk for developing dementia and could enable clinical trials aimed at finding treatments to prevent the cognitive effects of the disease.

Trends in emergency room visits and costs for patients with shingles

Science Daily (US) - 21/06/2017
A new study suggests that while emergency room visits for shingles has decreased for those vaccinated against either the chicken pox (18 to 19 years old) or the shingles (60 years and older), the patient population in-between (ages 20-59 years old) has experienced increased visits for the disease.

Specific diabetes medications to protect bone health recommended

Science Daily (US) - 21/06/2017
Type 2 diabetes (T2D) and osteoporosis often coexist in patients, but managing both conditions can be a challenge. A comprehensive review highlights the most effective treatment options for treating these conditions together.

Serotonin improves sociability in mouse model of autism

Science Daily (US) - 21/06/2017
Scientists have linked early serotonin deficiency to several symptoms that occur in autism spectrum disorder (ASD). The study examined serotonin levels, brain circuitry, and behavior in a mouse model of ASD. Experiments showed that increasing serotonergic activity in the brain during early development led to more balanced brain activity and improved the abnormal sociability of these mice.

Sleep-wake rhythms vary widely with age as well as amongst individuals of a given age

Science Daily (US) - 21/06/2017
The sleep rhythms that reflect circadian systems peak later in teenagers than in adults, and vary as much as 10 hours in individuals across at any ages, according to a new study.

Three ways neuroscience can advance the concussion debate

Science Daily (US) - 21/06/2017
While concussion awareness has improved over the past decade, understanding the nuances of these sports injuries, their severity, symptoms, and treatment, is still a work in progress. Neurologists and neurotraumatologists have reviewed the science of concussions and outlined several areas where neuroscience and clinical research can help create consensus in the field: definitions of what acute and chronic concussions are, diagnostics, and management and treatment.

Could flu during pregnancy raise risk for autism?

Science Daily (US) - 21/06/2017
Researchers found no evidence that laboratory-diagnosis alone of maternal influenza during pregnancy is associated with risk of autism spectrum disorder (ASD) in the offspring. They did, however, find a trend toward risk in mothers with a laboratory diagnosis of influenza and self-reported symptoms of severe illness. This trend did not achieve statistical significance.

Yarraman flu or horse flu? Words and graphics influence willingness to vaccinate

Science Daily (US) - 21/06/2017
'Yarraman flu is a virus quickly infecting the US...' The mock announcement was enough to make readers worry. But when the name of the hypothetical illness was changed to 'horse flu', readers reported being less motivated to get a vaccine that would prevent them from contracting the illness. Based on a survey of 16,510 participants from 11 countries, the findings show that the way health information is communicated, matters.

Neurons that regenerate, neurons that die

Science Daily (US) - 21/06/2017
Investigators report on a transcription factor that they have found that can help certain neurons regenerate, while simultaneously killing others.

Forgetting can make you smarter

Science Daily (US) - 21/06/2017
A new review paper proposes that the goal of memory is not to transmit the most accurate information over time, but to guide and optimize intelligent decision making by only holding on to valuable information.

New mechanism for genome regulation discovered

Science Daily (US) - 21/06/2017
The mechanisms that separate mixtures of oil and water may also help the organization of a part of our DNA called heterochromatin, according to a new study. Researchers found that liquid-liquid phase separation helps heterochromatin organize large parts of the genome into specific regions of the nucleus. The work addresses a long-standing question about how DNA functions are organized in space and time, including how genes are silenced or expressed.

Parkinson's is partly an autoimmune disease, study finds

Science Daily (US) - 21/06/2017
Researchers have found the first direct evidence that autoimmunity plays a role in Parkinson's disease, suggesting that immunosuppressants might play a role in treatment.

'Rosetta Stone' to decode immune recognition

Science Daily (US) - 21/06/2017
Medical researchers have developed an algorithm that predicts T cell recognition of antigens and sets the stage to more effectively harness the immune system.

New statistical method finds shared ancestral gene variants involved in autism's cause

Science Daily (US) - 21/06/2017
Researchers believe that theirs is the first rigorous statistical evidence that ancient variations in the human genome contribute to autism -- each, most likely, having a very small effect. The method investigatorss used in the new study was family-based and compared 'discordant sibilings,' one with and one without autism to a separate collection of affected individuals. The sample included over 16,000 people from nearly 4000 families.

Parents of newborn daughters take fewer risks study suggests

Science Daily (US) - 21/06/2017
A study has examined the effect of learning a child’s gender on parents’ attitudes towards risky behaviors. In this first of its kind study, the authors gathered prenatal and post-birth data from the pediatric wards of hospitals in both the United Kingdom and Ukraine, allowing for longitudinal and cross-sectional analyses of those attitudes.

Zika: Studying the 'rebound virus'

Science Daily (US) - 21/06/2017
Scientists are investigating how the Zika virus is able to find a safe harbor in an infected host's tissue and stage a rebound weeks after the virus was seemingly cleared by the immune system.

Genetic gains and losses in Tourette syndrome uncovered

Science Daily (US) - 21/06/2017
Researchers have identified structural changes in two genes that increase the risk of developing Tourette syndrome, a neurological disorder characterized by involuntary motor and vocal tics.
