High cholesterol triggers mitochondrial oxidative stress leading to osteoarthritis

by Dr. Jekyll in Lunatic Laboratories

High cholesterol might harm more than our cardiovascular systems. New research using animal models suggests that high cholesterol levels trigger mitochondrial oxidative stress on cartilage cells, causing them to die, and ultimately leading to the development of osteoarthritis.

Is it possible to normalize citation metrics?

by SciELO in SciELO in Perspective

Bibliometric indicators represent much more than an indication of the visibility, relevance and impact of an article. A researcher’s entire career profile can be summarized in one or more numerical productivity and impact indicators of his research. However, citation metrics vary considerably according to the area of knowledge, the publication age, the type of document and the coverage of the database where citations were accrued. Is it possible to normalize them? Here we discuss the challenge........ Read more »

Pathways to Substance Use and Abuse

by William Yates, M.D. in Brain Posts

Neuroscience medicine clinicians encounter patients every day who have both a mental and substance use disorder.This co-occurrence, or comorbidity, complicates diagnosis, treatment and outcome.The exact mechanism for this comorbidity issue is unclear.A recent study out of Washington University in St. Louis and King's College London provides some insight into this comorbidity issue.They examined participants in the Study of Addiction: Genetics and Environment (SAGE). These subjects provided genet........ Read more »

Forgetting Earth, forgetting Mars: Dementia, pollution, and space travel

by gdw in FictionalFieldwork

Forgetting Earth Dementia. Few words inspire greater fear in those of us who value (quasi-?) independent thought. The term ‘dementia’ encompasses various brain disorders that all share some scary traits: general decline in cognitive function, decreased ability to speak, and in later stages, being unable to take care of oneself. Unfortunately, as human lifespan increases […]... Read more »

Yet more on potential biomarkers and chronic fatigue syndrome

by Paul Whiteley in Questioning Answers

'Thick and fast' is probably the best way that I can describe the flurry of peer-reviewed scientific papers recently appearing (see here and see here for examples) talking about how chronic fatigue syndrome (CFS) (also linked to the diagnosis of myalgic encephalomyelitis, ME) might have some important biological processes attached to it.Now we can add the findings reported by Federica Ciregia and colleagues [1] (open-access) to the list and their observations that "the identification of bio........

Research improves the practice of environmentally sustainable actions in the medication process in hospitals

by SciELO in SciELO in Perspective

Researchers from the Studies and Research Group in Health Services Administration and Nursing Management from The Universidade Federal de São Paulo (UNIFESP) have developed studies to improve the practice of sustainable actions from an environmental point of view in hospitals. A recent doctoral thesis study carried out by researcher of the UNIFESP and member of the group, analyzed the sustainable actions taken by the nursing staff of an Intensive Care Unit (ICU) during the medication process an........

Social Priming - Does It Work After All?

by Neuroskeptic in Neuroskeptic_Discover

"Social priming" has been the punching-bag of psychology for the past few years.

The term "social priming" refers to the idea that subtle cues can exert large, unconscious influences on human behaviour. The classic example of a social priming effect was the "professor priming" study in which volunteers who completed a task in which they had to describe a typical professor, subsequently performed better on a general knowledge task. In other words, as the authors put it, "priming a stereotype o... Read more »

ADHD and conduct disorder long-term

by Paul Whiteley in Questioning Answers

Today I'm once again blogging about peer-reviewed research suggesting that when it comes to the long-term effects of attention-deficit/hyperactivity disorder (ADHD) on a person, there is some pretty solid evidence that addressing symptoms early could "potentially avert a wide range of future adverse outcomes."The paper making such a conclusion is the one from Holly Erskine and colleagues [1] who conducted a systematic review and meta-analysis pertinent to this topic; also taking into accoun........

Vitamins A and C help erase cell memory

by Dr. Jekyll in Lunatic Laboratories

Vitamins A and C aren't just good for your health, they affect your DNA too. Researchers have discovered how vitamins A and C act to modify the epigenetic 'memory' held by cells; insight which is significant for regenerative medicine and our ability to reprogramme cells from one identity to another.

Obesity in adolescent chronic fatigue syndrome (CFS)

Are There Too Few Jobs In Neuroscience?

Is European neuroscience facing a jobs crisis? Writing in The Lancet Neurology, Mario Bonato and Esperanza Jubera-Garcia sound the alarm:

As young European neuroscientists, we want to bring attention to the dramatic absence of professional long-term opportunities that researchers are facing mostly, although not exclusively, in the south of Europe.

In the past few years, young scientists from several European countries have been forced to move to other countries, or to quit research a... Read more »
