Vibrio parahaemolyticus type IV pili mediate interactions with diatom-derived chitin and point to an unexplored mechanism of environmental persistence.

Vibrio parahaemolyticus is a naturally occurring bacterium common in coastal waters where it concentrates in shellfish through filter feeding. The bacterium is a human pathogen and the leading cause of seafood-borne gastroenteritis. Presently there is little information regarding mechanisms of environmental persistence of V.

Genetic diversity of clinical and environmental Vibrio parahaemolyticus strains from the Pacific Northwest.

Since 1997, cases of Vibrio parahaemolyticus-related gastroenteritis from the consumption of raw oysters harvested in Washington State have been higher than historical levels. These cases have shown little or no correlation with concentrations of potentially pathogenic V. parahaemolyticus (positive for the thermostable direct hemolysin gene, tdh) in oysters, although significant concentrations of tdh(+) V.

Gli2 and p53 cooperate to regulate IGFBP-3- mediated chondrocyte apoptosis in the progression from benign to malignant cartilage tumors.

Clinical evidence suggests that benign cartilage lesions can progress to malignant chondrosarcoma, but the molecular events in this progression are unknown. Mice that develop benign cartilage lesions due to overexpression of Gli2 in chondrocytes developed lesions similar to chondrosarcomas when they were also deficient in p53. Gli2 overexpression and p53 deficiency had opposing effects on chondrocyte differentiation, but had additive effects negatively regulating apoptosis.

[Immunoglobulins in women with cancer of the uterine body (before treatment)].

Thirty-five women aged 40 to 79 years with the carcinoma of the body of the uterus were before treatment examined for humoral immunity to find out if the diminished function of the immunological system and immunodeficiency lead to an increased proneness to malignant diseases. Concentrations of total serum proteins, electrophoresis of proteins, and the quantitative determination of G-, A-, and M- immunoglobulins were performed. Lower mean values of IgG (11.
