Thinking about death can actually be a good thing

Thinking about death can actually be a good thing. An awareness of mortality can improve physical health and help us re-prioritize our goals and values, according to a new analysis of recent scientific studies. Even non-conscious thinking about death - say walking by a cemetery - could prompt positive changes and promote helping others.

HDAC9 gene can lead to obesity-induced body fat dysfunction

Cardiac researchers at the University of Cincinnati (UC) have found that a certain cellular pathway is linked to obesity-related disorders, like diabetes, heart disease and fatty liver disease.

Breast cancer treatment and classification revolutionized in landmark study

Breast cancer treatment could be revolutionized with patients offered more accurate diagnoses and better-targeted treatments after a study in which scientists genetically charted the disease. The research found that rather than being a single disease, breast cancer can be classified into 10 distinct types. It also identified several new genes that determine the aggressiveness of the cancer.

BuruliVac project getting closer to a vaccine

During a meeting in Lisbon, the partners of the BuruliVac research consortium found the project to be running smoothly, and getting closer to a vaccine against Buruli ulcer, a disfiguring and mutilating disease that causes a lot of suffering and now is difficult to treat. Several vaccine candidates work well in mice and are ready for further testing on blood of patients; one is ready for testing in mice.

Johns Hopkins Heart and Vascular Institute to open new building on April 29

Patients with heart and vascular disease will be cared for in spacious, state-of-the-art private rooms when Johns Hopkins opens its new hospital building to the first patients on April 29. The Johns Hopkins Heart and Vascular Institute occupies a major part of the 1.6 million-square-foot facility, which has 560 all-private patient rooms with private baths and 33 expansive operating rooms.

New passive vaccine reverses dangerous symptoms of cocaine overdose

Scientists are reporting development and successful testing in laboratory mice of a substance that shows promise for becoming the first antidote for cocaine toxicity in humans. According to a report in ACS' journal Molecular Pharmaceutics, the new so-called "passive vaccine" reversed the motor impairment, seizures and other dangerous symptoms of a cocaine overdose, which claims thousands of lives each year among users of the illicit drug.

Secondary Speckle Sensing Microscopy may rapidly and accurately diagnose malaria

Correctly and quickly diagnosing malaria is essential for effective and life-saving treatment. But rapid detection, particularly in remote areas, is not always possible because current methods are time-consuming and require precise instrumentation and highly skilled microscopic analysis. Now, a promising new optical imaging system, described in a paper published today in the Optical Society's (OSA) open-access journal Biomedical Optics Express, may make the diagnosis of this deadly disease much easier, faster, and more accurate.

First specific antidote for cocaine toxicity

Scientists at The Scripps Research Institute have shown that an injectable solution can protect mice from an otherwise lethal overdose of cocaine. The findings could lead to human clinical trials of a treatment designed to reverse the effects of cocaine in case of emergency. Cocaine is involved in more than 400,000 emergency-room visits and about 5,000 overdose deaths each year in the United States.

Differentiated luminal-like breast cancer cells can generate larger tumors

New findings in breast cancer research by an international team of scientists contradict the prevailing belief that only basal-like cells with stem cell qualities can form invasive tumors. Research led by Ole William Petersen at the University of Copenhagen (CU) and Mina Bissell of the Lawrence Berkeley National Laboratory (Berkeley Lab) and has shown that luminal-like cells with no detectable stem cell qualities can generate larger tumors than their basal-like counterparts.

Fluorescent fish shows oestrogenic chemicals’ impact on human body

Understanding the damage that pollution causes to both wildlife and human health is set to become much easier thanks to a new green-glowing zebrafish. Created by a team from the University of Exeter, the fish makes it easier than ever before to see where in the body environmental chemicals act and how they affect health.

Scientists identify hypervirulent Salmonella bacteria

UC Santa Barbara researchers have discovered Salmonella bacteria that are up to 100 times more capable of causing disease. Their findings may help prevent food poisoning outbreaks that continue to plague public health and the food industry.

New PBC tool for prioritizing laboratory-based CD-4 cell count testing

One of the major problems that has slowed progress toward universal access to life-saving antiretroviral therapy (ART) to treat AIDS in developing nations has been limited availability of laboratories and trained medical staff to conduct blood tests of immune system CD-4 T-cell levels that indicate when to start ART.

Study demonstrates how Parkinson's disease protein can spread in patient's brain

Last year, researchers from the Perelman School of Medicine at the University of Pennsylvania found that small amounts of a misfolded brain protein can be taken up by healthy neurons, replicating within them to cause neurodegeneration. The protein, alpha-synuclein (a-syn), is commonly found in the brain, but forms characteristic clumps called Lewy bodies, in neurons of patients with Parkinson's disease (PD) and other neurodegenerative disorders.

No added HIV risk with hormonal contraceptives

An HIV prevention trial that pre-dates the shift to antiretroviral (ARV)-based approaches is nonetheless helping to answer some of the most relevant and topical questions the field is facing today.

New brain cancer vaccine with material from own tumors proves effective in clinical trial

A new brain cancer vaccine tailored to individual patients by using material from their own tumors has proven effective in a multicenter phase 2 clinical trial at extending their lives by several months or longer. The patients suffered from recurrent glioblastoma multiforme-which kills thousands of Americans every year.
