Effect of type II collagen extract on immunosuppression induced by methotrexate in rats.

This study investigated the effect of type II collagen extract on SD rats with deteriorated immunity caused by methotrexate. The test samples were dosed once a day for 28 days by gastric gavage at dosage 250 mg/kg and 500 mg/kg after methotrexate treatment, and the changes on body weight, total blood leukocyte numbers, the percentages of B-cells, CD4+ T-cells and CD8+ T-cells in the blood and spleen were observed. The changes on body weight, the total blood leukocyte numbers, the total lymphocyte numbers in the spleen, the ratio of CD4+ and CD8+ T-cells in the blood and spleen were increased significantly in type II collagen extract groups as compared with the control group.

Expression of tumoral FOXP3 in gastric adenocarcinoma is associated with favorable clinicopathological variables and related with Hippo pathway.

FOXP3 is a transcription factor and well-known hallmark of immune suppressive T regulatory cells (Tregs). Recent studies indicate that, in addition to its association with Treg function in the immune system, FOXP3 plays an important role in tumor development. And important tumor suppressor relay between the FOXP3 and Hippo pathways was found in human cancer.

Tumoral FOXP3 has potential oncogenic function in conjunction with the p53 tumor suppressor protein and infiltrated Tregs in human breast carcinomas.

FOXP3 is a transcription factor and a well-known hallmark of immune suppressive T regulatory cells. Recent studies indicate that in tumor cells, FOXP3 plays an important role in tumor development in addition to its well-established Treg function in the immune system. We investigated tumoral FOXP3 expression in breast carcinoma, and the relationships between tumoral FOXP3 expression and p53, HER-2/ErbB2, Ki67, infiltrated Tregs, and other clinicopathological variables.

Leiomyosarcoma of the ovarian vein: a case report with radiological findings.

Leiomyosarcomas of the ovarian vein are very rare. Four cases have been reported in the English language clinical literature. We present a case of leiomyosarcomas where the use of multi-detector CT had a substantial role in the establishment of the preoperative diagnosis.

Fitz-Hugh-Curtis syndrome: CT findings of three cases.

Clinical manifestations and computed tomography (CT) findings of Fitz-Hugh-Curtis syndrome (FHCS) are relatively well stabilized as right upper quadrant abdominal pain and hepatic capsular enhancement because of perihepatitis associated with pelvic inflammatory disease caused by N. gonorrhoeae and C. trachomatis.

A study on the relationship between biodegradability enhancement and oxidation of 1,4-dioxane using ozone and hydrogen peroxide.

Advanced oxidation involving O(3)/H(2)O(2) was used to eliminate 1,4-dioxane and to enhance the biodegradability of dioxane-contaminated water. Oxidation experiments were carried out in a bubble column reactor operating in fed-batch. The rate of dioxane removal and enhancement in biodegradability was investigated at hydrogen peroxide to ozone ratios between 0 and 0.
