New gold nanoparticle method allows for tracking studies of virus pathways in tissues

Enteroviruses are pathogenic viruses infecting humans. This group consists of polioviruses, coxsackieviruses, echoviruses and rhinoviruses. Enteroviruses are the most common causes of flu, but they also cause serious symptoms such as heart muscle infections and paralysis. Recently, enteroviruses have been linked with chronic diseases such as diabetes.

Study uncovers how enzymes could be used to identify predisposition to ROS-related diseases

A UT Arlington chemist doing National Science Foundation-funded research on enzymes that regulate human biology has uncovered characteristics that could be used to identify predisposition to conditions such as heart disease, diabetic ulcers and some types of cancer.

Researchers develop a class of compounds that may help eradicate Chagas disease

A team of researchers from Canada has developed a class of compounds which may help eradicate a neglected tropical disease that is currently hard to kill in its chronic form. The research was published ahead of print in Antimicrobial Agents and Chemotherapy.

Decreasing levels of reactive oxygen species can break cycle of unhealing wounds

Chronic wounds affect an estimated 6.5 million Americans at an annual cost of about $25 billion. Further, foot blisters and other diabetic ulcers or sores account for the vast majority of foot and leg amputations in the United States today.

American scientists introduce novel gel for sealing wounds

In first-aid situations, wounds must be quickly and effectively closed to stop blood loss and prevent infection. For treatment on arrival in a hospital, the temporary seal must be reopened, which often causes additional damage to the injured tissue. In the journal Angewandte Chemie, American scientists have now introduced a novel gel for sealing wounds. The gel can later be dissolved and gently removed.

NAC amino acid may offer new treatment options for psychiatric disorders

Improved understanding of the roles of inflammation and oxidative stress in psychiatric disorders has generated new leads in the search for novel therapies. One such investigative compound currently in clinical trials is an amino acid, N-Acetyl Cysteine (NAC), which appears to reduce the core symptoms of bipolar disorder, schizophrenia, depression, autism and cravings in addictions including cocaine, cannabis abuse and cigarette smoking.

Scientists devised technique to make antibody-drug conjugates, basis of new therapies

Chemists at The Scripps Research Institute (TSRI) have devised a new technique for connecting drug molecules to antibodies to make advanced therapies.

Immune marker predicts transplant success, improves selection of bone marrow donors

The risk of death following bone marrow transplantation can be reduced about 60 percent using a new technique to identify bone marrow donors who make the most potent cancer-fighting immune cells, according to research from St. Jude Children's Research Hospital. The findings appear in the September 16 online issue of the Journal of Clinical Oncology.

Research: Treatment with antioxidants may help reduce behavioral issues linked to NF1

New research in mouse models suggests that treatment with antioxidants may help reduce behavioral issues linked to the genetic nervous system disorder Neurofibromatosis 1 (NF1) and an associated condition called Costello syndrome.

Newly developed approach could benefit basic medical research and help detect H2S in environment

University of Oregon chemists have developed a selective probe that detects hydrogen sulfide (H2S) levels as low as 190 nanomolar (10 parts per billion) in biological samples.

Cow antibodies points to new ways for making human medicines

Humans have been raising cows for their meat, hides and milk for millennia. Now it appears that the cow immune system also has something to offer. A new study led by scientists from The Scripps Research Institute (TSRI) focusing on an extraordinary family of cow antibodies points to new ways to make human medicines.

Molecular switch protects salmonella from harm during infection

For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment during infection and might protect it from harm, researchers report this week online in the Proceedings of the National Academy of Sciences Early Edition.

Cinnamon compounds show some promise in the effort to fight Alzheimer's disease

Cinnamon: Can the red-brown spice with the unmistakable fragrance and variety of uses offer an important benefit? The common baking spice might hold the key to delaying the onset of -- or warding off -- the effects of Alzheimer's disease.

Vitamin C kills drug-resistant TB bacteria in lab

In a striking, unexpected discovery, researchers at Albert Einstein College of Medicine of Yeshiva University have determined that vitamin C kills drug-resistant tuberculosis bacteria in laboratory culture.

Individual hydroxymethylcytosine molecules in DNA detected by new method involving chemical modification and nanopore analysis

Changes in the bases that make up DNA act as markers, telling a cell which genes it should read and which it shouldn’t. In the journal Angewandte Chemie, a British team has now introduced a new method that makes it possible to enrich the rare gene segments that contain the modified base hydroxymethylcytosine and to identify individual hydroxymethylcytosine molecules in DNA. Such modifications are associated with autoimmune diseases and cancer.

Metallothioneins play major role in virulence of Cryptococcus neoformans

Metallothioneins, proteins able to capture metal ions, play a major role in the virulence of Cryptococcus neoformans, a fungal pathogen which causes severe infections in immunodeficient and immunocompetent individuals (AIDS patients, transplant receivers, etc.)

Red coloration might represent some physiological benefit: Research

Red coloration-historically seen as costly in vertebrates-might represent some physiological benefit after all, according to research published in the journal Physiological and Biochemical Zoology.

Enterococcal cytolysin synthetase helps form distinctly different, 3-D protein ring structures

While working out the structure of a cell-killing protein produced by some strains of the bacterium Enterococcus faecalis, researchers stumbled on a bit of unusual biochemistry. They found that a single enzyme helps form distinctly different, three-dimensional ring structures in the protein, one of which had never been observed before.

SPARC protein acts much like ibuprofen to heal tissues inflamed by tumors

Cancer researchers are increasingly aware that in addition to genetic mutations in a cancer itself, characteristics of the surrounding tissue can promote or suppress tumor growth. One of these important tissue characteristics is inflammation - most cancers prosper in and attach to inflamed tissue and so many cancers have developed ways to create it.
