Study provides guidelines on how to combine antiangiogenic drugs with nanotherapeutics

Combining two strategies designed to improve the results of cancer treatment - antiangiogenesis drugs and nanomedicines - may only be successful if the smallest nanomedicines are used. A new study from Massachusetts General Hospital (MGH) researchers, appearing in Nature Nanotechnology, finds that normalizing blood vessels within tumors, which improves the delivery of standard chemotherapy drugs, can block the delivery of larger nanotherapy molecules.

Reprogramming the Brain to Health Symposium to take place on April 12

Jordan Grafman, PhD, will speak at the Reprogramming the Brain to Health Symposium at The University of Texas at Dallas on April 12. An expert on brain function and behavior, Dr. Grafman's topic is human belief systems in the brain.

First study to demonstrate link between social status and genetic regulation in primates

The ranking of a monkey within her social environment and the stress accompanying that status dramatically alters the expression of nearly 1,000 genes, a new scientific study reports. The research is the first to demonstrate a link between social status and genetic regulation in primates on a genome-wide scale, revealing a strong, plastic link between social environment and biology.

Changes in corneal thickness occur in patients at early stages of FECD

A national consortium of researchers has published new findings that could change the standard of practice for those treating Fuchs' Endothelial Corneal Dystrophy (FECD), a disease characterized by cornea swelling that can eventually lead to the need for corneal transplantation.

Study: Body and head lice are the same species

A new study offers compelling genetic evidence that head and body lice are the same species. The finding is of special interest because body lice can transmit deadly bacterial diseases, while head lice do not.

Mayo Clinic introduces Breast Cancer Genome Guided Therapy Study

The Breast Cancer Genome Guided Therapy Study (BEAUTY Project) will help physicians tailor chemotherapy to breast cancer patients based on their individual genomes and the genomes of their tumors.

KLF15 gene governs the body's ability to burn fat during exercise

While exercise is accepted universally as the most beneficial prescription physicians can write for patients, little is known about the molecular mechanisms that generate its widespread health benefits. Researchers from Case Western Reserve School of Medicine have shed light on this mystery by discovering that a genetic factor, Kruppel-like Factor 15 (KLF15), governs the body's ability to burn fat during exercise.

OphthaliX completes CF101 preclinical studies on Anterior Uveitis

OphthaliX announced today the completion of preclinical studies, showing that its CF101 drug candidate is efficacious in treating Anterior Uveitis

Aristolochic acid exposure leads to kidney failure and UUC

Aristolochic acid (AA), a component of a plant used in herbal remedies since ancient times, leads to kidney failure and upper urinary tract cancer (UUC) in individuals exposed to the toxin.

Black fly's blood-sucking tactics may be used for medical advancement

Black flies drink blood and spread disease such as river blindness-creating misery with their presence. A University of Georgia study, however, proves that the pesky insects can be useful.

Novel anti-leukemia compound with little toxicity successfully treats zebrafish

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans - even those resistant to conventional therapies - according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Delivering chemotherapy drugs with nanobubbles more deadly to cancer cells

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles," researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) are developing new methods to inject drugs and genetic payloads directly into cancer cells.

Bimodal genes can define molecular subtypes of ovarian cancer

Scientists from Duke University Medical Center have determined that genes acting as molecular "on/off" switches can define clinically relevant molecular subtypes of ovarian cancer, providing ideal potential targets for use in clinical prognostic and diagnostic testing.

Chemotherapy based on individual genomes and genomes of tumors

The Breast Cancer Genome Guided Therapy Study (BEAUTY Project) will help physicians tailor chemotherapy to breast cancer patients based on their individual genomes and the genomes of their tumors.

A step closer to correcting unhealthy gene mutations with diet

Scientists have moved a step closer to correcting some unhealthy gene mutations with diet, according to a new research report appearing in the April 2012 issue of the journal GENETICS.

Five significant genetic associations for hypothyroidism found

Using its unique online research platform, 23andMe, a leading personal genetics company, has found five significant genetic associations for hypothyroidism in the largest known genome-wide association study of hypothyroidism conducted to date. The details of the study are now available online in the journal PLoS ONE.

Researchers question wisdom of blocking DP1 in patients prone to cardiovascular disease

Niacin, or vitamin B3, is the one approved drug that elevates "good" cholesterol (high density lipoprotein, HDL) while depressing "bad" cholesterol (low density lipoprotein , LDL), and has thereby attracted much attention from patients and physicians. Niacin keeps fat from breaking down, and so obstructs the availability of LDL building blocks.

Heart cells starved of nutrients less likely to be damaged during ischemia, reperfusion

Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.

First study to examine links between neurodevelopmental disorders and maternal metabolic conditions

A major study of the relationships between maternal metabolic conditions and the risk that a child will be born with a neurodevelopmental disorder has found strong links between maternal diabetes and obesity and the likelihood of having a child with autism or another developmental disability.
