We investigated the effects of androgen and taxol on the androgen-responsive LNCaP and androgen-independent DU145 prostate cancer cell lines. Cells were treated for 48 and 72 h with 0.05-1 nM of the synthetic androgen R1881 and with 100 nM taxol. Treatment of LNCaP cells with 0.05 nM R1881 led to increased cell proliferation, whereas treatment with 1 nM(More)
We utilized the transgenic adenocarcinoma mouse prostate (TRAMP) model to study the formation of abnormal mitosis in malignant tumors of the prostate. The results presented here are focused on centrosome and centriole abnormalities and the implications for abnormal cell divisions, genomic instability, and apoptosis. Centrosomes are microtubule organizing(More)
1',1'-Dimethylheptyl-Delta-8-tetrahydrocannabinol-11-oic acid (CT-3) is a novel cannabinoid that is under development by Atlantic Pharmaceuticals as an anti-inflammatory and analgesic drug. The objective of the study was to investigate the effects of CT-3 on overt symptom complex (Irwin's test), nociception, gastrointestinal (GI) ulceration, and(More)
Calcium and P balance and mobilization from bone were evaluated through 20 wk of lactation to determine the timing and extent of net resorption of bone mineral and mineral balance in lactating dairy cows. Eighteen Holstein cows were blocked by parity and calving date and randomly assigned to 1 of 3 dietary treatments: high (1.03%, HI), medium (0.78%, MED),(More)
BACKGROUND The potential for novel antiplatelet and antithrombin agents to contribute to periprocedural bleeding complications of percutaneous coronary revascularization is poorly defined. In the Evaluation of c7E3 Fab in Preventing Ischemic Complications of High-Risk Angioplasty (EPIC) trial, the periprocedural use of aspirin, heparin, and a chimeric(More)
Alterations of video monitor and laparoscopic camera position may create perceptual distortion of the operative field, possibly leading to decreased laparoscopic efficiency. We aimed to determine the influence of monitor/camera position on the laparoscopic performance of surgeons of varying skill levels. Twelve experienced and 12 novice participants(More)
4-hydroxynonenal (4HNE) is a major product of peroxidative membrane lipid destruction and exerts a variety of deleterious actions through formation of covalent adducts with cellular nucleophiles. Consequently, a number of cellular enzyme systems exist that are capable of detoxifying this reactive aldehyde by oxidation, reduction, or conjugation with(More)
Twenty-seven multiparous Jersey cows were randomly assigned to receive an oral bolus containing corn starch (control, CON), corn starch plus 15 mg of 25-hydroxyvitamin D(3) (25-OH), or 15 mg of cholecalciferol (D(3)) at 6 d before expected parturition. Cows were maintained in individual box stalls from 20 d before expected parturition and fed a common diet.(More)
Kupffer cells have been documented to play an important role in the early events of liver injury and regeneration by releasing biologically active mediators such as interleukin-6 (IL-6). 4-Hydroxy-trans-2-nonenal (4-HNE), a major end product of lipid peroxidation, has multiple cytotoxic effects and is implicated in chemical-induced liver injury.(More)
Calcium loss and muscle atrophy are two of the main metabolic changes experienced by astronauts and crew members during exposure to microgravity in space. Calcium and cytoskeletal events were investigated within sea urchin embryos which were cultured in space under both microgravity and 1 g conditions. Embryos were fixed at time-points ranging from 3 h to 8(More)
