Short Communication: Relationship Between Body Growth And Mammary Development In Dairy Heifers, L F. Silva, M J. Vandehaar, Brian K. Whitlock, R P. Radcliff, H A. Tucker Oct 2002

Short Communication: Relationship Between Body Growth And Mammary Development In Dairy Heifers, L F. Silva, M J. Vandehaar, Brian K. Whitlock, R P. Radcliff, H A. Tucker

Brian K Whitlock, PhD, DVM, DACT

Our objective was to determine if prepubertal rate of body weight (BW) gain, independent of diet, was related to mammary development of dairy heifers. Data from two studies recently conducted at Michigan State University were used to identify factors, within a dietary treatment group, that would account for variation in first lactation milk production or amount of mammary parenchymal DNA at the time of puberty. Factors analyzed for variation in milk production during first lactation were: postpartum BW, prepubertal BW gain, gestational BW gain, postpartum BW gain, body condition score (BCS) at breeding, and BCS at calving. Factors analyzed for …

Distribution Of Different Fibronectin Isoforms In The Extracellular Matrices Of Human Term Placenta, Ayşe Yasemi̇n Demi̇r Weusten Jan 2002

Distribution Of Different Fibronectin Isoforms In The Extracellular Matrices Of Human Term Placenta, Ayşe Yasemi̇n Demi̇r Weusten

Turkish Journal of Medical Sciences

Fibronectins are considered to be molecules that play important roles in cell migration and cell differentiation. Fibronectin molecules are thought to influence the differentiation of trophoblasts and the adhesion of these cells to maternal tissues. The aim of the present study was to analyze the distribution of fibronectin isoforms and to evaluate the differences between matrix-type fibrinoids, and other types of matrices produced by both maternal and fetal tissues. Tissue samples were collected from different sites of human term placentas. By using immunohistochemistry, the expression of fibronectin isoforms was determined and they were demonstrated by SDS-PAGE and Western blotting methods. …

Aim: To measure serum vitamin D levels of pregnant women in the last trimester and to determine factors affecting serum levels. Methods: Seventy-eight pregnant women, 19-39 years old and having their third trimester between March and May 2000, were enrolled. Serum Ca, P and alkaline phosphatase and 25-hydroxyvitamin D_3 levels were measured in venous blood samples during the third trimester. Maternal age, education, socioeconomic status, number of gravida, nutrition, dressing habits and daily exposure time to sunlight were determined and their correlation with serum vitamin D levels were analyzed statistically. Results: The mean age of mothers was 26.1±5.1 years. The …
