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.

PUMA protein offers critical insights for developing new anti-cancer drugs

The discovery of how the activities of the protein p53 initiate signals that trigger cell suicide offers critical insights for developing new anti-cancer drugs, according to investigators from St. Jude Children's Research Hospital.

HOXA1 is a gene that's been looking for a disorder for a long time

Researchers at Children's Hospital Boston, who specialize in studying the genetics of rare eye-movement disorders, have found a rare genetic syndrome whose implications go far beyond the eye, raising intriguing questions about human cardiovascular and brain development.

Clioquinol appears to block the genetic action of Huntington's disease

Clioquinol, an antibiotic that was banned for internal use in the United States in 1971 but is still used in topical applications, appears to block the genetic action of Huntington's disease in mice and in cell culture, according to a study reported by San Francisco VA Medical Center (SFVAMC) researchers.

Depression may hasten the progression of heart disease

In a study of 32 people with heart failure, the 14 patients who felt the most depressed had nearly twice the levels of this protein in their blood.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

New way to assess risk of breast cancer recurrence

Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast.

Two proteins for the diagnosis of lung diseases

Lung function pathology takes in some 200 diseases which have much radiological and pathological data in common, and which can greatly shorten the life of the patient, the last resort being a lung transplant.

Prostate cancer manipulates an important group of signaling proteins called Wnts to establish itself in bone

Prostate cancer is a cruel disease. Left untreated, prostate cancer cells often metastasize, or spread, to bone where they form fracture-prone tumors that are extremely painful.

Mushrooms are a great source of antioxidants

Using a new, more sensitive-testing approach they developed for fungi, Penn State food scientists have found that mushrooms are a better natural source of the antioxidant ergothioneine than either of the two dietary sources previously believed to be best

Daydreaming linked to Alzheimer's disease

According to new research, Alzheimer's disease may be due to abnormalities in the regions of the brain that operate the "default state", a term used to describe the cognitive state people defer to when musing, daydreaming, or thinking to themselves.

Supermolecules strike blow to cancer cells

Chemistry and biology researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change.

Anti-ageing gene could improve effects of getting old

According to scientists in the United States they have discovered a gene that can keep mice alive for 30% longer than normal.

Compound might defeat African sleeping

One of the most devastating diseases in sub-Saharan Africa almost disappeared in the late 1950s.

The role of antigenic drive and tumor-infiltrating accessory cells in the pathogenesis of Helicobacter-induced MALT lymphoma

Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.

Parts of the brain used in daydreaming are the same areas that fail in people who have Alzheimer's disease

Researchers who used five different medical imaging techniques to study the brain activity of 764 people, including those with Alzheimer's disease, those on the brink of dementia, and healthy individuals, have found that the areas of the brain that young, healthy people use when daydreaming are the same areas that fail in people who have Alzheimer's disease.

New post-graduate qualification will help counter a world-wide shortage of forensic medicine experts

A new degree designed to equip doctors and scientists with the expertise needed to investigate deaths resulting from acts of genocide, terrorism, natural disasters such as Tsunami, transport accidents and drug abuse will be launched this week at an international Forensic Science conference in Hong Kong.
