The scientific study of the nature of disease and its causes, processes, development, and consequences. Also called pathobiology.
Researchers find first evidence of virus in malignant prostate cells in prostate cancer — XMRV retrovirus is associated with more aggressive tumors of prostate gland. – XMRV (Xenotropic murine leukemia virus-related virus) — a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in malignant human prostate cancer cells.
New research links social stress to harmful fat deposits, heart disease – Social stress could be an important precursor to heart disease by causing the body to deposit more fat in the abdominal cavity, speeding the harmful buildup of plaque in blood vessels, a stepping stone to the number one cause of death in the world.
Mathematical modeling predicts response to Herceptin in breast cancer patients. – Cancer researchers are turning to mathematical models to help answer important clinical questions, and a new paper in Cancer Research, a journal of the American Association for Cancer Research, illustrates how the technique may answer questions about Herceptin resistance.
Common allergy drug reduces obesity and diabetes in mice – Researchers have linked type 2 diabetes and obesity with immunology. These new research studies published in Nature Medicine, by Harvard Medical School researchers.
Regardless of the duration of use, the formulation, estrogen dose, regimen, progestin type, and route of administration, hormone therapy was associated with an increased risk of ovarian cancer. – Compared with women who have never taken hormone therapy, those who currently take it or who have taken it in the past are at increased risk of ovarian cancer.
Study may explain why HIV progresses faster in women than in men with same viral load — Pathways related to elevated immune activation could lead to new treatment strategies. – One of the continuing mysteries of the HIV/AIDS epidemic is why women usually develop lower viral levels than men following acute HIV-1 infection but progress faster to AIDS than men with similar viral loads.
Mayo Clinic study using structural MRI may help accurately diagnose dementia patients – Researchers developed STAND-Map – a framework for MRI-based differential diagnosis of three common neurodegenerative disorders: Alzheimer’s disease, frontotemporal lobar degeneration, and Lewy body disease using Structural MRI.
Language Skills in Your Twenties May Predict Risk of Dementia Decades Later – People who have superior language skills early in life may be less likely to develop Alzheimer’s disease decades later, despite having the hallmark signs of the disease, revealed by researchers.
Researchers find possible environmental causes for Alzheimer’s, diabetes — Call for reducing nitrate levels in fertilizer and water, detoxifying food and water. – Increased levels of nitrates in our environment and food increases disease risks including Alzheimer’s disease, diabetes mellitus and Parkinson’s disease, revealed by researchers.
Study challenges routine use of MRI scans to evaluate breast cancer — Test is linked to delays in treatment, increase in mastectomy rates. – Women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment, revealed by researchers.
Found: 1 in 3 billion — The spelling mistake in the genetic code that causes a type of ovarian cancer. – Eureka! Vancouver scientists from the Ovarian Cancer Research (OvCaRe) Program at BC Cancer Agency and Vancouver Coastal Health Research Institute have discovered that there appears to be a single spelling mistake in the genetic code of granulosa cell tumours, a rare and often untreatable form of ovarian cancer.
New accurate diagnostic test for swine H1N1 influenza using RT-PCR technology – A new, easy-to-perform method for detecting both seasonal influenza A virus and the emerging H1N1 swine-derived influenza A virus in human clinical samples offers a fast, sensitive, and cost-effective diagnostic test that runs on standard laboratory equipment.
