Pancreatic islet cell tumors were induced in 38 of 44 male Wistar rats (86%), which survived 9 to 14 months following the various treatment schedules. A single i.v. injection of streptozotocin alone, 30, 40, 50, or 65 mg/kg of body weight produced adenomas of pancreatic islet cells in 8 of 9 (89%), 6 of 7 (86%), 2 of 4 (50%), and 1 of 2 rats (50%), respectively. The neoplasms were seen in all o...

OBJECTIVE This study was conducted to evaluate the effects of dietary protein sources (soybean meal, SBM; low-gossypol cottonseed meal, LCSM; double-zero rapeseed meal, DRM) on laying performance, egg quality, and plasma parameters of laying hens. METHODS A total of 432 32-wk-old laying hens were randomly divided into 6 treatments with 6 replicates of 12 birds each. The birds were fed diets c...

Recently, we have shown that high molecular weight polymers inhibit cortical granule exocytosis at total osmolalities only slightly higher than that of sea water (Whitaker, M., and J. Zimmerberg. 1987. J. Physiol. 389:527-539). In this study, we visualize the step at which this inhibition occurs. Lytechinus pictus and Strongylocentrotus purpuratus eggs were exposed to 0.8 M stachyose or 40% (wt...

The effects of intravenous injection of synthetic human pancreatic growth hormone-releasing factor-44-NH2 (hpGRF-44) and synthetic thyrotropin releasing hormone (TRH), or hpGRF-44 in combination with TRH on growth hormone (GH), thyrotropin (TSH), and prolactin (PRL) release in dairy female calves (6- and 12-month-old) were studied. When 0.25 microgram of hpGRF-44 per kg of body weight (bw) was ...

The aim of this study was to evaluate the effects of tomato supplementation on the normal rat heart and the role of oxidative stress in this scenario. Male Wistar rats were assigned to two groups: a control group (C; n = 16), in which animals received a control diet + 0.5 mL of corn oil/kg body weight/day, and a tomato group (T; n = 16), in which animals received a control diet supplemented wit...

Aims: Modifiable lifestyle factors, as cardiorespiratory fitness (CRF) and body mass, may prevent hypertension. However, it remains unclear whether blood pressure is associated with CRF, independently of body mass index (BMI). Thus, the purpose was to study the relationship between CRF, body composition and blood pressure among 40-44 year old men and women. Methods: During 2007-2008, 12,900 men...
