Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Discovery could help improve diagnosis and treatment for anxiety disorders

Draw a map of the brain when fear and anxiety are involved, and the amygdala-the brain's almond-shaped center for panic and fight-or-flight responses-looms large.

Researchers challenge prevailing belief about role of protein in abnormal cell proliferation

In a study to be published this week, a research team is challenging a prevailing belief about the behavior of a human protein linked to the formation of cancer, possibly breathing new life into the search for therapies that will inhibit that protein from "turning on" genes involved in abnormal cell proliferation.

Researchers identify new drugs to protect brain cells from neurological disease

Researchers have identified a compound that mimics one of the brain's own growth factors and can protect brain cells against damage in several animal models of neurological disease.

Discovery challenges understanding of blood cell development

University of Utah researchers led an international team of scientists that is the first to report on the previously undescribed ability of platelets to reproduce themselves in the circulation. Their revolutionary findings were published online Jan. 19, 2010, in the journal Blood.

Preoperative CT may help reduce unnecessary surgeries in women with suspected acute appendicitis

Preoperative computed tomography (CT) may help reduce unnecessary surgeries in women of reproductive age with suspected acute appendicitis, according to a new study appearing in the February issue of the journal Radiology.

Patients with COPD could benefit from treatment with drugs that block sestrin function

Chronic obstructive pulmonary disease (COPD) is defined by emphysema and/or chronic bronchitis. It destroys the normal architecture of the lung and inhibits the mechanical aspects of breathing, which prevents necessary gas exchange. Patients suffer from coughing fits, wheezing, and increased incidence of lung infections.

HZI researchers explore novel therapies to keep the immune system young and functional for healthy aging

By comparing the immune responses of both, young and old mice, to bacterial infection they found that the number of macrophages, one of the major cell populations involved in the elimination of infecting bacteria, decreases rapidly in aged mice. This decline in the number of fighters and the associated weakness of the immune defense may be responsible for the age-associated increase in susceptibility to infections.

Universite de Montreal researchers are developing leptin-based pill to control hunger

A Universit- de Montr-al research team is developing a pill composed of leptin, the protein that tells our brain to stop eating. "Mice deprived of leptin will not stop eating. They become so big they have trouble moving around," says Mo-se Bendayan, a pathology professor at the Universit- de Montr-al Faculty of Medicine who has studied the leptin protein extensively.

Findings may yield novel therapeutic strategies for late-stage breast cancer

Researchers from the Boston University School of Medicine (BUSM) have determined how the TGFβ-Smad signaling pathway, which is over activated in late-stage cancers, is responsible for the "epigenetic memory" that maintains unique patterns of regulatory DNA hypermethylation causing silencing of critical genes that facilitate breast cancer progression.

Labeled menus may lead to reduced calorie intake in children

In a new study, the amount of calories selected by parents for their child's hypothetical meal at McDonald's restaurants were reduced by an average of 102 calories when the menus clearly showed the calories for each item. This is the first study to suggest that labeled menus may lead to significantly reduced calorie intake in fast food restaurant meals purchased for children.

The American Journal of Pathology: Highlights from February 2010 issue

A group led by Dr. Peter Lloyd Jones at the University of Dundee, Dundee, Scotland; the University of Colorado Denver, Aurora, CO; and the University of Pennsylvania, Philadelphia, PA has demonstrated that tenascin-C affects proto-oncogene function in breast cancer. Their report can be found in the February 2010 issue of The American Journal of Pathology.

Current research suggests flu may predispose to secondary bacterial infections

Current research suggests that the flu may predispose to secondary bacterial infections, which account for a significant proportion of mortality during flu pandemics. The related report by Lee et al, "A mouse model of lethal synergism between influenza virus and Haemophilus influenzae," appears in the February 2010 issue of The American Journal of Pathology.

Celerus Diagnostics demonstrates Rapid ISH on its Wave RPD System

Through collaborative efforts with multiple industry partners, Celerus Diagnostics has successfully demonstrated Rapid ISH™ (in-situ hybridization) on its forthcoming Wave RPD System.

Loud music can increase risk for hearing loss

Listening to an iPod while working out feels like second nature to many people, but University of Alberta researcher Bill Hodgetts says we need to consider the volume levels in our earphones while working up a sweat.

College of American Pathologists unveils resources and features on cancer in MyBiopsy.org

There's nothing more frightening than hearing the words "you have cancer" from your physician. With this diagnosis, many questions come to mind ... What's next? Will I survive? How do I tell my loved ones? The last is the most important for many people after receiving a cancer diagnosis: I need accurate information right now.

Copper-free version of click chemistry crafted to create biomolecular probes

For the first time, the widely used molecular synthesis technique known as click chemistry has been safely applied to a living organism. Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have crafted a unique copper-free version of click chemistry to create biomolecular probes for in vivo studies of live mice. Conventional click chemistry reactions require a copper catalyst that is toxic to cells and organisms.

TCGA study reveals four distinct molecular subtypes of GBM

The most common form of malignant brain cancer in adults, glioblastoma multiforme (GBM), is not a single disease but appears to be four distinct molecular subtypes, according to a study by the Cancer Genome Atlas (TCGA) Research Network. The researchers of this study also found that response to aggressive chemotherapy and radiation differed by subtype.

Fraunhofer USA CMB receives $60,000 gift from ProTecs to complete vaccine manufacturing plant

The Fraunhofer USA Center for Molecular Biotechnology, a not-for-profit, 501 (c3) research organization, announced today that it has received a $60,000 gift from ProTecs, Inc., to complete its new, state of-the-art vaccine manufacturing plant in Newark, Delaware.

New research at Rhode Island Hospital identifies a treatment for glioblastomas

New research at Rhode Island Hospital has identified a treatment in animal models for glioblastomas - deadly brain tumors which, once diagnosed, offer a poor prognosis and relatively short life expectancy.

Repeated exposure to tobacco smoke makes lung cancer much worse

Repeated exposure to tobacco smoke makes lung cancer much worse, and one reason is that it steps up inflammation in the lung. Scientists at the University of California, San Diego School of Medicine have found that mice with early lung cancer lesions that were repeatedly exposed to tobacco smoke developed larger tumors - and developed tumors more quickly - than unexposed animals.
