Drug reduces hospitalizations and cost of treating young children with sickle cell anemia

The study is the largest ever focusing on the economic impact of the drug hydroxyurea (see structure below)

 in children with the inherited blood disorder. The result supports expanded use of the drug to extend the length and quality of life for sickle cell anemia patients of all ages, said Winfred Wang, M.D., a member of the St. Jude Department of Hematology and principal investigator of the multicenter federally funded trial known as BABY HUG.

"We estimate that hydroxyurea cut overall annual medical expenses about $3,000 for each patient by helping patients avoid disease complications that require inpatient hospital care," said Wang, who is first and corresponding author of the Pediatrics study. "We expect those savings will grow along with patients, whose symptoms often increase in severity and frequency as they age."

About 100,000 individuals in the U.S. and millions worldwide have sickle cell disease, which leaves them at risk for premature death and disability. The disease is the most common genetic disorder affecting African-American individuals, but those from other ethnic and racial backgrounds also inherit mutations in the hemoglobin gene. The mutations result in blood cells that are prone to assuming the sickled shape that gives the disease its name and that leave patients at increased risk for episodes of acute pain, stroke, organ damage and other complications.

Scientists fish for new epilepsy model and reel in potential drug

According to new research on epilepsy, zebrafish have certainly earned their stripes. Results of a study in Nature Communications suggest that zebrafish carrying a specific mutation may help researchers discover treatments for Dravet syndrome (DS), a severe form of pediatric epilepsy that results in drug-resistant seizures and developmental delays.

Synthetic polymer could stop the spread of HIV

The researchers created the large molecule with several sugar molecules, known as glycopolymers (Glycopolymer is synthetic polymer with pendant carbohydrates). By using different sugars attached to the macromolecule in solution, the scientists were able to investigate which sugar molecules were the most effective in inhibiting the potential binding of the virus.

They then measured how the designed macromolecules compete with the virus to bind to the dendritic cells of the immune system at different concentrations.

"These are preliminary but encouraging results for potentially preventing the spread of the HIV by sexual contact," said Dr Remzi Becer from Queen Mary's School of Engineering and Materials Science.

"We've shown that our synthetic molecule binds to the immune cell, which in turn blocks the virus from attaching and entering. The precisely designed macromolecules could be an ingredient of a condom cream or vaginal gel to act as a physical barrier from allowing the virus into the body."

Dr Becer added: "While this isn't a cure for HIV, it is a novel approach that could dramatically slow down the spread of HIV by sexual contact, and a model that could be replicated to treat other sexually transmitted diseases."

Alzheimer's 'missing link' found: Promising target for new drugs

Yale School of Medicine researchers have discovered a protein that is the missing link in the complicated chain of events that lead to Alzheimer's disease, they report in the Sept. 4 issue of the journal Neuron. Researchers also found that blocking the protein with an existing drug can restore memory in mice with brain damage that mimics the disease.

FDA Advisory Committee Unanimously Recommends Approval Of Bayer's Riociguat In Two Pulmonary Hypertension Indications

We know that, Riociguat is (BAY 63-2521) is a novel drug that is in clinical development by Bayer. It is a stimulator ofsoluble guanylate cyclase (sGC). At the moment Phase III clinical trials investigate the use of riociguat as a new approach to treat two forms of pulmonary hypertension (PH): chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension (PAH). Riociguat constitutes the first drug of a novel class of sGC stimulators.

Drug used for blood cancers may stop spread of breast cancer cells

In continuation of my update on Decitabine

A drug used to treat blood cancers may also stop the spread of invasive breast cancer, researchers at Mayo Clinic in Florida have discovered. Their study, published online in Breast Cancer Research, found that in the lab and in animals, the drug decitabine turns on a gene coding for protein kinase D1 (PRKD1) that halts the ability of cancer cells to separate from a tumor and spread to distant organs.

Study: Type 2 diabetic patients treated with DPP-4 linagliptin experience reductions in blood glucose levels

Data published in The Lancet showed that elderly people with Type 2 Diabetes (T2D) treated for 24 weeks with the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin, marketed by Boehringer Ingelheim and Eli Lilly and Company, experienced significant reductions in blood glucose levels (HbA1c) compared with those receiving placebo. In addition, the overall safety and tolerability profile of linagliptin was similar to placebo, with no significant difference in hypoglycaemia.

Watermelon juice relieves post-exercise muscle soreness

Encarna Aguayo and colleagues cite past research on watermelon juice's antioxidant properties and its potential to increase muscle protein and enhance athletic performance. But scientists had yet to explore the effectiveness of watermelon juice drinks enriched in L-citrulline. Aguayo's team set out to fill that gap in knowledge.

They tested natural watermelon juice, watermelon juice enriched in L-citrulline (ABOVE STRUCTURE) and a control drink containing no L-citrulline on volunteers an hour before exercise. Both the natural juice and the enriched juice relieved muscle soreness in the volunteers. L-citrulline in the natural juice (unpasteurized), however, seemed to be more bioavailable -- in a form the body could better use, the study found.

Combined therapy could repair and prevent damage in Duchenne muscular dystrophy, study suggests

Results from a clinical trial of eteplirsen, {RNA, [P-deoxy-P-(dimethylamino)](2',3'-dideoxy-2',3'-imino-2',3'-seco)(2'a→5')(C-m5U-   C-C-A-A-C-A-m5U-C-A-A-G-G-A-A-G-A-m5U-G-G-C-A-m5U-m5U-m5U-C-m5U-A-G),    5'-[P-[4-[[2-[2-(2-hydroxyethoxy) ethoxy]ethoxy] carbonyl]-1-piperazinyl]-N,N-   dimethylphosphonamidate]}  a drug designed to treat Duchenne muscular dystrophy, suggest that the therapy allows participants to walk farther than people treated with placebo and dramatically increases production of a protein vital to muscle growth and health. The study, led by a team in The Research Institute at Nationwide Children's Hospital, is the first of its kind to show these results from an exon-skipping drug -- a class of therapeutics that allows cells to skip over missing parts of the gene and produce protein naturally....
