Genetic Factors Behind Mosquitoes Resistance to Malaria Identified

... When a mosquito is infected with a parasite that causes malaria, a biochemical reaction is triggered that physically transforms TEP1 into an active state capable of grabbing on to the parasites surface and targeting it for termination, they say. In a study, reported online in the Proceedings of the Nati...

Delay in Cancer Diagnosis for Children

...pidly. Studies characterizing and explaining the causes of delays in diagnosis are in their infancy. The few studies that have been done have been limited by methodological weaknesses, such as relying on retrospective chart reviews. As a prelude to a large audit study of diagnosis and treatment delays ...

Obesity Drug may Hold Potent Cancer Treatments

...tumour cells and blocks the protein's function and causes cell death. The study was conducted by a team of researchers including Steven Kridel and W. Todd Lowther at Wake Forest University School of Medicine. As part of the study, scientists analysed prostate cancer cells to see which enzymes were expre...

Boffins Identify Gene That can Protect Humans from Nephronopthisis

...serious kidney disease . NPHP is a disease that causes kidney degeneration during childhood and kidney failure requiring organ transplantation. The insights might help design effectual and non-invasive therapies. The team has discovered that mutations in the gene GLIS2 can lead to nephronopthisis (NPHP...

Water Hyacinth is Used for Health Improvements in Africa

... fungi. Additionally, water enters the tunnels and causes the plant mats to sink as the plants deteriorate further. Wind and wave action can accelerate the destruction of the weed started by the insects. No herbicide spraying was used in the Ugandan program, only mechanical removal and biocontrol, yet by...

New Therapies for Kidney Diseases

...y poorly understood. NPHP is such a disease; it causes the kidneys to degenerate and shrink starting early on in childhood often leading to renal failure before the age of 30. So far, kidney transplantation in early age has been the only way to save patients suffering from NPHP. With a new mouse model...

Ice Bath by Sports Star Questioned

...shift lactic acid. The theory is that the icy cold causes the blood vessels to tighten, and drains the blood along with waste products such as lactic acid out of the legs. But on the contrary, a study in the British Journal of Sports Medicine now claims that the opposite may be true. Ice baths have beco...

Uncooked Fish may Cause Liver Cancer

"Although carbohydrate quality was not the main focus in the AREDS, we were fortunate that the investigators had collected the dietary carbohydrate information we needed to do our analyses," says Taylor, who is also a...

Scientists Identified Obesity Control Switch

...hite fat -the type that stores excess calories and causes waistlines to bulge. In some of the mouse experiments, the Dana-Farber investigators inserted PRDM16 genes into precursors of white fat, and implanted the white fat precursors under the skin of the animals. The PRDM16 gene coaxed those cells to gen...

Scientists Identify "master Switch" for Brown Fat in Mice

...not in white fat, which stores excess calories and causes waistlines to bulge. In some mouse experiments, the researcher inserted PRDM16 genes into precursors of white fat, and implanted the white fat precursors under the skin of the animals. The PRDM16 gene coaxed those cells to generate brown fat cells...

Newborn Screening Tests for Babies

Understanding HIV Interference With Infected Cell Division

...HIV. Human immunodeficiency virus type 1 (HIV-1) causes AIDS by depleting essential immune cells called CD4+T lymphocytes in infected individuals, resulting in a compromised immune system. At the center of this process is the HIV protein, viral protein R (Vpr), which stops infected CD4+T cells from dividi...
