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.

Transcutaneous cervical esophageal ultrasound can not substitute for 24-h pH monitoring or manometry

24-h pH monitoring and esophageal manometry are the gold standards of methods used for diagnosing GER and esophageal motor disorders, respectively.

Small papillary thyroid cancers are NOT clinically insignificant

Patients with micropapillary thyroid cancer - small tumors equal to or less than 1 centimeter—and tumors even smaller, less than 1 millimeter (mm - are more common and not without a risk as previously thought, according to a new study presented at the 78th Annual Meeting of the American Thyroid Association (ATA) in New York.

Specific immune deficiency pinpointed as likely cause of ulcerative colitis

In a series of mouse experiments, researchers at the Harvard School of Public Health (HSPH) have pinpointed a specific immune deficiency as the likely fundamental cause of ulcerative colitis, a chronic, sometimes severe inflammatory disease of the colon or large intestine that afflicts half a million Americans.

Prostate cancer treatment may encourage spread of cancer cells

According to a new study by researchers in the U.S. the popular prostate cancer treatment, androgen deprivation therapy, may in fact encourage the spread of cancer cells throughout the body.

Additional biopsy-scoring data may help determine prostate cancer prognosis

Men with certain scores and patterns based on prostate cancer biopsy were found to be at higher risk of PSA-failure, suggesting that this measurement could help predict the risk of prostate cancer recurrence, according to preliminary research published in the October 3 issue of JAMA.

HPV testing and vaccinations may change scope of training for lab professionals

By now we have all heard or seen commercials promoting testing and vaccination of human papillomavirus (HPV), a virus with more than 100 strains, 30 of which are sexually transmitted.

Depression, aging, and proteins made by a virus may all play role in heart disease

Researchers here have linked an increase in two immune system proteins essential for inflammation to a latent viral infection and proposed a chain of events that might accelerate cardiovascular disease.

Tree bark compound gambogic amide stimulates growth, survival of brain cells

Researchers have identified a compound in tree bark that mimics the chemical reactions of a naturally occurring molecule in the brain responsible for stimulating neuronal cell signaling.

Androgen deprivation therapy for prostate cancer may encourage spread of disease

A popular prostate cancer treatment called androgen deprivation therapy may encourage prostate cancer cells to produce a protein that makes them more likely to spread throughout the body, a new study by Johns Hopkins researchers suggests.

H5N1 able to pass through placenta to fetus and infect organs other than lungs in adults

The H5N1 strain of the bird flu virus can pass through the placenta of pregnant women to the unborn fetus, and can infect organs other than the lungs in adults. These are the conclusions of authors of an Article in The Lancet.

Loss of TDP-43 gene found to be related to age-related neurological disorders

Researchers at Mayo Clinic in Jacksonville have discovered how loss of a gene can lead to accumulation of toxic proteins in the brain, resulting in a common dementia, and they say this mechanism may be important in a number of age-related neurological disorders.
