New research on bed bug's ability to withstand genetic bottleneck of inbreeding

New research on the bed bug's ability to withstand the genetic bottleneck of inbreeding, announced today at the American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting, provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally.

Scientists help uncover evolutionary history of TAS2R38 bitter taste receptor gene

Long the bane of picky eaters everywhere, broccoli's taste is not just a matter of having a cultured palate; some people can easily taste a bitter compound in the vegetable that others have difficulty detecting. Now a team of Penn researchers has helped uncover the evolutionary history of one of the genes responsible for this trait.

Web-based video game players contribute to analysis of DNA sequences

Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer's, diabetes and cancer over the past year. They are the users of a web-based video game developed by Dr. J-r-me Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette.

King's College London submits first clinical grade xeno-free hES cell lines to the UKSCB

Stem cell scientists at King's College London will announce they have submitted to the UK Stem Cell Bank (UKSCB) their first clinical grade human embryonic stem (hES) cell lines that are free from animal-derived products, known as 'xeno-free' stem cells.

Supercomputer simulations give insight into proteins involved in drug detoxification

Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are giving scientists unprecedented access to a key class of proteins involved in drug detoxification.

Evaluation method supports soy as high-quality protein

The importance of protein in the human body is undeniable. However, the idea of what makes a protein a "quality protein" has not been as easy to determine. A new study from the Journal of Agriculture and Food Chemistry takes a closer look at the criteria for determining the quality of a protein.

SG Austria, Nuvilex use live cell encapsulation technology and treat diabetes in animal model

Nuvilex, Inc. announced today their affiliate SG Austria and partners have successfully treated diabetes in an established, recognized animal model utilizing live encapsulated cells.

Pretreatment fasting glucose could block breast cancer progression

An increasing understanding of molecular pathways that regulate breast and colorectal cancer development and progression has produced new therapeutic agents, including the biologic agents trastuzumab, bevacizumab, and cetuximab. Identifying the indicators that are likely to predict which patients will achieve the best response to these agents represents a major challenge for contemporary oncologists.

Scientists understand how nervous system becomes wired during early development

Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development.

Biologists discover how fruit flies can provide solutions to human pain, control insect-borne diseases

Studies of a protein that fruit flies use to sense heat and chemicals may someday provide solutions to human pain and the control of disease-spreading mosquitoes.

New alveoli continue to be formed as lungs grow

A ground-breaking international study into the ways lungs grow and develop has challenged existing medical understanding that our lungs are completely formed by the age of three.

Researchers discover new tick-borne infection

Researchers at the University of Gothenburg's Sahlgrenska Academy have discovered a brand new tick-borne infection. Since the discovery, eight cases have been described around the world, three of them in the Gothenburg area, Sweden.

INT-777 shows promise against metabolic syndrome

Heart disease is a major cause of death in industrialised countries, and is strongly associated with obesity and diabetes. Many scientists believe that what links these conditions is a chronic, low-grade inflammation.

Report shows how mutant gene influences lipid metabolism

People who carry a malfunctioning copy of a particular gene are especially good at clearing fat from their systems. The report in the December Cell Metabolism, a Cell Press publication, shows how the mutant gene influences metabolism in this way.

Fatty livers burn more fat, not less

When our livers become loaded with fat, it isn't because they are slacking. A new study of human patients in the December Cell Metabolism shows that fatty livers actually burn more fat, not less. All that "hard work" may be at the root of the organ damage that comes with nonalcoholic fatty liver disease (NAFLD), a condition associated with insulin resistance that affects about one in three in the U.S. population.

Study evaluates whether genetic GST polymorphisms increase risk of ALD in alcoholics

It has been widely observed that only a small percentage of alcoholics develop cirrhosis of the liver, the most advanced form of alcoholic liver disease (ALD); the reason why all alcoholics do not develop such disease is not known. The present study from Spain, that includes original work and a meta-analysis, evaluates whether genetic polymorphisms that determine levels of glutathione-S-transferases (GST) relate to the risk of developing ALD among alcoholics.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Biosensors can detect oxidant production in living organism

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative stress. Oxidative stress arises in tissues when there is an excess of what are called reactive oxygen species.

Transient absorption tracks carbon nanotubes in living cells and bloodstream

Researchers have demonstrated a new imaging tool for tracking structures called carbon nanotubes in living cells and the bloodstream, which could aid efforts to perfect their use in biomedical research and clinical medicine.
