Comparative effects of pravastatin and rosuvastatin on carbohydrate metabolism in an experimental diabetic rat model.

Statin treatment may increase the risk of diabetes; there is insufficient data on how statins affect glucose regulation and glycemic control and the effects of statins on liver enzymes related to carbohydrate metabolism have not been fully studied. Therefore, we aimed to compare the effects of the statin derivatives, pravastatin, and rosuvastatin, on carbohydrate metabolism in an experimental diabetic rat model. Female Wistar albino rats were used and diabetes was induced by intraperitoneal injection of streptozotocin.

Distribution of cytoskeletal proteins in the cat testis during the pre-pubertal and post-pubertal periods.

Cytoskeletal proteins not only define the shape of cells, but also have critical roles in their proliferation, migration and motility, as well as in the establishment and maintenance of tissue organization and integrity. Furthermore, these proteins influence the physiological processes of the male reproductive system and are found in the structure of some cells. This study aimed to determine differences between the pre- and post-pubertal periods for the localization and distribution of actin, desmin, vimentin and cytokeratin-18 in the testes, epididymides and ductus deferentes of Persian and Turkish Angora and Van cats, using immunohistochemistry.

The distribution of some homeobox proteins in the bovine placenta during gestation.

Homeobox proteins are transcription factors known to be involved in the molecular basics of body model formation and transformation. Some homeobox proteins are known to play critical roles in the control of the extraembryonic development of the placenta during gestation and in the regulation of uterine and placental physiology in adults. The gravid uteruses and placentas of 27 Holsteins cows, obtained from private slaughterhouses, were used in this study.
