Study on resistance of harmful bacteria to antibiotics

A study by two Florida State University biochemists makes an important contribution to science's understanding of a serious problem causing concern worldwide: the growing resistance of some harmful bacteria to the drugs that were intended to kill them.

Anticancer drug Cisplatin induces side effects

Cisplatin, an anticancer drug widely used for treating various types of tumor, can induce side effects in the short term. A team of scientists, mostly from CNRS and the Université de Nice has provided first in vitro evidence that this antitumor agent modifies the sensitivity of cellular pressure sensors. This completely novel mechanism could help to elucidate certain neurological side effects of cisplatin hitherto unexplained.

Researchers investigate whole-genome data to uncover new mutations for CAD risk

The Coronary ARtery DIsease Genome-wide Replication And Meta-Analysis (CARDIoGRAM) published in Circulation Cardiovascular Genetics, an American Heart Association journal consists of data from every published whole-genome study on genetic mutations in heart attack or CAD risk. Researchers are also pooling data from several unpublished genome-wide association studies to see if any new mutations can be uncovered.

Insulin-sensitizing drugs may offer new treatments for kidney failure

Evidence reported in the October issue of Cell Metabolism, a Cell Press publication, offers a completely new explanation for why people with diabetes account for more than half of all patients requiring dialysis or kidney transplantation. It appears that insulin has a significant influence on the structure and proper function of a particular group of very specialized cells, known as podocytes, that are integral to the kidney's ability to do its job filtering blood.

Researchers discover biomarker for allergy can originate from mother

Allergies occur when the defence mechanisms of the immune system malfunction and misread normal substances entering the body as invading pathogens. Antibodies are part of our biochemical arsenal for combating viruses, bacteria, parasites and other alien substances, but during an allergic reaction the antibody, known as IgE, is directed against usually harmless substances such as grass pollen, nuts, pets or eggs. However, researchers from COPSAC (Copenhagen Studies on Asthma in Childhood) at the Faculty of Health Sciences, University of Copenhagen recently discovered indications that IgE in the blood of the umbilical cord could originate from the mother, and decided to conduct a focused study on this.

Saneron receives grant to develop safety guidelines for transplanting HUBC cells in Alzheimer's disease

The National Institutes of Health has awarded a three-year, $2.6-million grant to the University of South Florida and Tampa-based biotechnology company Saneron-CCEL Therapeutics, Inc., to establish dosing and safety guidelines for transplanting human umbilical cord blood cells (HUBC) into animal models of Alzheimer's disease.

Amino acid mixture increases survival in mice

When mice are given drinking water laced with a special concoction of amino acids, they live longer than your average mouse, according to a new report in the October issue of Cell Metabolism, a Cell Press publication. The key ingredients in the supplemental mixture are so-called branched-chain amino acids, which account for 3 of the 20 amino acids (specifically leucine, isoleucine, and valine) that are the building blocks of proteins.

Cancer cells utilize energy-rich intermediates of sugar metabolism: Research

Cancer research is facing a radical change of direction. Cancer cells do not obtain their energy from the breakdown of sugar to carbon dioxide and water, but from energy-rich intermediates of sugar metabolism instead.

Researchers develop new method to assess stress vulnerability

An impressive body of knowledge has linked stress to illness vulnerability. Yet stress is inextricably linked to everyday life. A group of researchers of the University of Bologna headed by Prof. Giovanni Fava has developed a new method for assessing it that is described in the current issue of Psychotherapy and Psychosomatics.

New approach method could simplify study and treatment of human diseases

Therapeutic antibodies can be an efficient alternative when common drugs do not work anymore. However, antibodies obtained from blood of animals such as mice could not be used: The human immune system recognizes them as foreign and rejects them.
