Microcystin present in Canadian lakes in every province

Nutrient pollution, one of the greatest threats to our freshwater resources, is responsible for the algal blooms that blanket our lakes and waterways in summer months. Large blooms of cyanobacteria ('blue green algae') can cause fish kills, increase the cost of drinking water treatment, devalue shoreline properties, and pose health risks to people, pets, and wildlife. A new paper just published in the Canadian Journal of Fisheries and Aquatic Sciences shows that microcystin, a toxin produced by cyanobacteria, is present in Canadian lakes in every province.

Empa physicist analyzes structure and composition of soot particles

Since June 2012, it is official: The World Health Organisation (WHO) has classified diesel soot as a lung carcinogen. Artur Braun, a physicist at Empa and an X-ray spectroscopy expert, has made crucial contributions to analyzing the structure and composition of soot particles.

NIH grants aim at creating 3-D tissue chips to help identify drug safety signals

Seventeen National Institutes of Health grants are aimed at creating 3-D chips with living cells and tissues that accurately model the structure and function of human organs such as the lung, liver and heart. Once developed, these tissue chips will be tested with compounds known to be safe or toxic in humans to help identify the most reliable drug safety signals - ultimately advancing research to help predict the safety of potential drugs in a faster, more cost-effective way.

Neogen fourth quarter revenues increase 11.4% to $48,545,000

Neogen Corporation announced today that its revenues for the fourth quarter of its FY 2012, which ended May 31, increased 11.4% from the previous year's comparable quarter to $48,545,000. Net income for the fiscal year's final quarter was $0.25 per share, the same as the prior year's fourth quarter of $0.25 per share.

Researchers discover potential drug targets that might reduce ventilator-induced lung inflammation

When hospital patients need assistance breathing and are placed on a mechanical ventilator for days at a time, their lungs react to the pressure generated by the ventilator with an out-of-control immune response that can lead to excessive inflammation, new research suggests.

Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

ADCT, CRT sign agreements to develop ADCs against cancer

Cancer Research Technology (CRT), the commercial arm of Cancer Research UK, and Switzerland-based ADC Therapeutics Sarl (ADCT) announce today that they have signed agreements to develop cancer treatments called Antibody Drug Conjugates (ADCs) using CRT antibodies and peptides, and ADCT's 'warhead' and linker chemistries.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Paralympic medicine: challenges and rewards

In the second Series paper, Paralympic medicine, Nick Webborn of the British Paralympic Association and Peter Van de Vliet of the International Paralympic Committee Medical and Scientific Department, outline some of the issues that arise for health-care professionals when maintaining health in elite athletes with a variety of impairments.

Study shows cells from different Parkinson’s patients have unique drug responses

Researchers have taken a step toward personalized medicine for Parkinson's disease, by investigating signs of the disease in patient-derived cells and testing how the cells respond to drug treatments.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Botulinum toxin may help prevent arm tremor in people with MS

Botulinum toxin may help prevent shaking or tremor in the arms and hands of people with multiple sclerosis (MS), according to new research published in the July 3, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology.

New toxicology testing method requires lesser number of fish

A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC). Their research, published today in the journal Ecotoxicology, could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.

Scientists identify novel mechanism behind bacterial pathogenesis

Scientists have identified a new mechanism of bacterial pathogenesis. The results of the research project, partly funded by the Academy of Finland, have been published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Study shows how brain insulin resistance contributes to neurodegeneration in AD

Rhode Island Hospital researcher Suzanne de la Monte, M.D., has found a link between brain insulin resistance (diabetes) and two other key mediators of neuronal injury that help Alzheimer's disease (AD) to propagate.

Study: Neurons that control hunger linked to non-food associated behaviors

Researchers at Yale School of Medicine have zeroed in on a set of neurons in the part of the brain that controls hunger, and found that these neurons are not only associated with overeating, but also linked to non-food associated behaviors, like novelty-seeking and drug addiction.

Structure of human P-glycoprotein in a moving 3D computer model

A picture is worth 1,000 words when it comes to understanding how things work, but 3D moving pictures are even better. That's especially true for scientists trying to stop cancer by better understanding the proteins that make some chemotherapies unsuccessful.
