Beneficial or not beneficial: that is the question for IL-1 inhibition in atherosclerosis

Atherosclerosis is a disease of the major arterial blood vessels. It is one of the major causes of heart attack and stroke. The proinflammatory molecule IL-1 has been linked to atherosclerosis and a clinical trial has been launched in which an antibody specific for IL-1-beta is being studied for its effects on the severe clinical complications of atherosclerosis (i.e., heart attack and stroke). However, a team of researchers led by Gary Owens, at the University of Virginia, Charlottesville, has now generated data in mice that raise potential concerns about this clinical ...

EDITOR'S PICK Another potential obstacle to developing an HIV vaccine A clinical trial testing a candidate HIV vaccine known as the STEP study was halted in September 2007 after interim analysis indicated that the vaccine did not work. Moreover, subsequent analyses indicated that the vaccine made some individuals more susceptible to HIV, in particular individuals who had pre-existing immune effectors (antibodies) that recognized a component of the vaccine (adenovirus serotype 5 [Ad5]). A team of researchers led by Juliana McElrath, at the Fred Hutchinson Cancer Research ...

Tests for biomarker may help determine diagnosis of heart attack within hours

CHICAGO – For patients admitted to an emergency department with chest pain, use of a contemporary or highly sensitive test for levels of troponin I (a protein in muscle tissue) may help rule-out a diagnosis of heart attack, while changes in the measured levels of this biomarker at 3 hours after admission may be useful to confirm a diagnosis of heart attack, according to a study in the December 28 issue of JAMA. One of the most common reasons patients seek care in an emergency department is for acute chest pain. "Early identification of individuals at high and intermediate ...

Perception of inappropriate care frequent among ICU workers

CHICAGO – A survey of nurses and physicians in intensive care units (ICUs) in Europe and Israel indicated that the perception of inappropriate care, such as excess intensity of care for a patient, was common, and that these perceptions were associated with inadequate decision sharing, communication and job autonomy, according to a study in the December 28 issue of JAMA. "Clinicians perceive the care they provide as inappropriate when they feel that it clashes with their personal beliefs and/or professional knowledge. Intensive care unit workers who provide care perceived ...

Analysis does not support genetic test before use of anti-clotting drug

CHICAGO – Although the U.S. Food and Drug Administration (FDA) has recommended that a certain type of genetic testing (for the genotype CYP2C19) be considered before prescribing the drug clopidogrel to identify individuals who may be less responsive to the medication, a review and analysis of previous studies did not find an overall significant association between the CYP2C19 genotype and cardiovascular events, according to a study in the December 28 issue of JAMA. Clopidogrel is an antiplatelet drug used by approximately 40 million patients worldwide to treat or prevent ...

Possible Defenses To A DUI Charge

You are sitting in your car, watching the red lights in your rearview mirror. The officer exits their vehicle and begins walking toward your car. The next thing you know, you have been charged with a DUI. What do you do now? You may think you have no chance, that even though you did not feel intoxicated or impaired, the blood alcohol content reading of the breathalyzer showed you were over the limit, and you are as good as convicted. Machines don't make mistakes, do they? Challenging A DWI Charge While it may seem an open and shut case, there may be multiple ...

Oxidative DNA damage repair

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations ...

Irikaitz archaeological site -- host to a 25,000-year-old pendant

The recent discovery of a pendant at the Irikaitz archaeological site in Zestoa (in the Basque province of Gipuzkoa) has given rise to intense debate: it may be as old as 25,000 years, which would make it the oldest found to date at open-air excavations throughout the whole of the Iberian Peninsula. This stone is nine centimetres long and has a hole for hanging it from the neck although it would seem that, apart from being adornment, it was used to sharpen tools. The discovery has had great repercussion, but it is not by any means the only one uncovered here by the team ...

Targeted blocking of cell death prevents fatal condition septic shock

Ghent, Belgium 27 December 2011 - Researchers of VIB and UGent have discovered a new approach to preventing septic shock, an often fatal extreme inflammatory reaction of the body. It is the most frequent cause of death at intensive care departments in hospitals. In sepsis, acute inflammation is attended by low blood pressure and blood clots, causing the organs to stop working. Only recently, the Brazilian football legend Socrates, died of the consequences of this condition. In a new study in the top journal Immunity, Peter Vandenabeele and colleagues of VIB-UGent described ...

Elderly can be as fast as young in some brain tasks, study shows

COLUMBUS, Ohio – Both children and the elderly have slower response times when they have to make quick decisions in some settings. But recent research suggests that much of that slower response is a conscious choice to emphasize accuracy over speed. In fact, healthy older people can be trained to respond faster in some decision-making tasks without hurting their accuracy – meaning their cognitive skills in this area aren't so different from younger adults. "Many people think that it is just natural for older people's brains to slow down as they age, but we're finding ...

Children don't give words special power to categorize their world

COLUMBUS, Ohio – New research challenges the conventional thinking that young children use language just as adults do to help classify and understand objects in the world around them. In a new study involving 4- to 5-year-old children, researchers found that the labels adults use to classify items – words like "dog" or "pencil" – don't have the same ability to influence the thinking of children. "As adults, we know that words are very predictive. If you use words to guide you, they won't often let you down," said Vladimir Sloutsky, co-author of the new study and professor ...

Mutation in gene that's critical for human development linked to arrhythmia

(SALT LAKE CITY)— Arrhythmia is a potentially life-threatening problem with the rate or rhythm of the heartbeat, causing it to go too fast, too slow or to beat irregularly. Arrhythmia affects millions of people worldwide. The cardiac conduction system (CCS) regulates the rate and rhythm of the heart. It is a group of specialized cells in the walls of the heart. These cells control the heart rate by sending electrical signals from the sinoatrial node in the heart's right atrium (upper chamber) to the ventricles (lower chambers), causing them to contract and pump blood. The ...

Childhood hypersensitivity linked to OCD

In childhood, rituals like regular schedules for meal, bath, and bed times are a healthy part of behavioral development. But combined with oral and tactile sensitivities, such as discomfort at the dentist or irritation caused by specific fabrics, these rituals could be an early warning sign of adult Obsessive Compulsive Disorder (OCD). According to Prof. Reuven Dar of Tel Aviv University's Department of Psychology, hypersensitivity and excessive adherence to childhood rituals may foreshadow the onset of OCD as the child ages. He first suspected the link while working ...

Missouri Mesothelioma Victims Not Limited to Workers' Comp Claims

Generally, under Missouri law, workers' compensation provides an "exclusive remedy" to employees who suffer work-related injuries. Thus, most workers must rely on workers' compensation benefits when they are injured on the job and generally are not able to bring a civil negligence lawsuit against their employers. However, a recent state Court of Appeals decision has changed this rule as it relates to Missouri asbestos exposure victims and workers suffering from other occupational diseases. These injured workers are no longer limited by the workers' compensation ...

Using computer programs and mathematical formulas, Richard Conn Henry, an astrophysicist in the Krieger School of Arts and Sciences, and Steve H. Hanke, an applied economist in the Whiting School of Engineering, have created a new calendar in which each new 12-month period is identical to the one which came before, and remains that way from one year to the next in perpetuity. Under the Hanke-Henry Permanent Calendar, for instance, ...

A new theory emerges for where some fish became 4-limbed creatures

EUGENE, Ore. -- A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This theorized image of such a drastic adaptation to changing environmental conditions, however, may, itself, be evolving into a new picture. University of Oregon scientist Gregory J.

To children (but not adults) a rose by any other name is still a rose

Two vital parts of mentally organizing the world are classification, or the understanding that similar things belong in the same category; and induction, an educated guess about a thing's properties if it's in a certain category. There are reasons to believe that language greatly assists adults in both kinds of tasks. But how do young children use language to make sense of the things around them? It's a longstanding debate among psychologists. A new study in Psychological Science, a journal of the Association for Psychological Science, challenges the predominant answer. ...

Members of small monkey groups more likely to fight

Small monkey groups may win territorial disputes against larger groups because some members of the larger, invading groups avoid aggressive encounters. In a new report published in the Proceedings of the National Academy of Sciences, Margaret Crofoot, post-doctoral fellow at the Smithsonian Tropical Research Institute and the Max Planck Institute of Ornithology, and Ian Gilby, professor at Duke University, show that individual monkeys that don't participate in conflicts prevent large groups from achieving their competitive potential.
