Fish oil, it's been touted as an answer to Alzheimers, arthritis and even weight-loss but now a Queensland University of Technology researcher will test its health benefits in people with chronic kidney disease.
Dietitian Rachel Zabel, from QUT's Institute of Health and Biomedical Innovation in Brisbane, Australia, will investigate the effects of fish oil on patients with kidney disease undergoing dialysis.
A recent describes a new agent, called "Zorro-LNA," which has the potential to stop genetic disorders in their tracks. In the study, researchers from the Karolinska Institute in Stockholm, Sweden, describe how they developed Zorro-LNA to bind with both strands of a gene’s DNA simultaneously, effectively disabling that gene.
This development has clinical implications for virtually every human condition caused by or worsened by dominant defective genes. Examples include: Huntington’s disease, familial high cholesterol, polycystic kidney disease, some instances of glaucoma and colorectal cancer, and neurofibromatosis, among others.
The heart is one of the most energy demanding organs of the human body. Its failure to function properly accounts for 600,000 deaths each year. Similarly, the rainbow trout, native to the Pacific Northwest and beloved as a sport- and food fish, requires dynamic and sustained cardiac function to maintain its health and swimming activity.
Tungsten began increasing in trees in Fallon, Nev. several years before the town's rise in childhood leukemia cases, according to a new research report.
The amount of tungsten in tree rings from Fallon quadrupled between 1990 and 2002, whereas the amount in tree rings from nearby towns remained the same, according to a research team led by Paul R. Sheppard of The University of Arizona's Laboratory of Tree-Ring Research.
Triptolide is derived from a Chinese medicinal herb, named Lei Gong Teng, which has been used in traditional medicine to treat cancer, inflammation, and auto-immune diseases and, more recently, also has been tested in Phase I clinical trials as an anti-tumor agent.
Using a compound from Triptolide, Yale University researcher Dr. Craig Crews has been able to prevent the formation of kidney-destroying cysts in a mouse model of polycystic kidney disease. This ability holds out hope for what would be the first treatment, other than kidney transplant or frequent dialysis, for one of the most lethal of all kidney diseases worldwide.
Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells. This groundbreaking work led to the first molecular classification of malignant melanoma and may help to explain how, by becoming more like unspecialized stem cells, the aggressive melanoma cell gained enhanced abilities to migrate, invade and metastasize while virtually undetected by the immune system.
For the first time, scientists have used a laboratory mouse model to mimic the development of human alcohol-induced breast cancer.
Alcohol (EtOH) consumption -- even moderate -- is a well-established risk factor for breast cancer in women. A recent study showed that 60 percent of female breast cancers worldwide were attributable to alcohol consumption. Nevertheless, the mechanisms of alcohol-induced breast cancer are poorly understood.
Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery. That is until now.
A group of Dartmouth and UCLA researchers, who normally work on genes involved in aging and cancer in animals, discovered the last piece of the puzzle, they report in a study published in the Journal of Biological Chemistry.
A role for a microRNA in the immune system has been shown by study of one of the world’s first microRNA knockout mouse. The microRNA acts as a lynchpin to balance the response of immune defences and the researchers suggest the corresponding human gene will have a similar vital role.
MicroRNAs (also known as siRNAs - short, interfering RNAs) are short (22-25 base) sequences that do not code for protein, but can lead to destruction of other RNA molecules or can interfere with their translation. They bind to corresponding bases in the target RNA. The mature microRNAs are derived from larger precursor molecules.
A generation of children born with HIV are now coming of age and reaching sexual maturity. Girls in this group who are sexually active are experiencing a higher number than expected of cervical abnormalities, a new study finds.
Researchers monitored the rate of first-time pregnancies, genital health and Pap test results of 638 girls, ages13 and over, who became infected with HIV around the time of birth. Nearly 50 percent of the girls had abnormal cervical cells.
