Long-term selection for increased ovulation rate (1984 to 2002) has resulted in a unique ovarian phenotype in the MARC Twinner cattle population. Ovulation rate and frequency of bilateral ovulations were examined by rectal palpation in 29,547 estrous cycles for 3,910 heifers (12 to 18 mo of age) in this population. Bilateral ovulations (one corpus lutuem [CL] on each ovary) were of interest bec...

PURPOSE To investigate the expression of RDH10, an all-trans retinol dehydrogenase identified in the retinal pigment epithelium (RPE), in retinal Muller cells. METHODS The RDH10 protein levels in mouse eyecups and bovine tissues were examined by Western blot analysis using a polyclonal antibody against RDH10. The cellular localization in the retina was determined by immunohistochemistry. Expr...

ABSTRACT: The downer cow syndrome (DCS) is characterized by an alert showing inability or reluctance to stand for 12 hours more. This paper reported clinical, laboratory, and pathological findings in a Guzerá heifer with rhabdomyolysis, pigmenturia acute renal failure following DCS. A 17-month-old was transported via 350-km ride truck showed sternal recumbency severe difficulty standing walking...

OBJECTIVE To determine the effects of 2 conjugated linoleic acid (CLA) isomers (cis-9, trans-11 and trans-10, cis-12) on synthesis of prostaglandin (PG) E(2) and F(2α) and expression of prostaglandin H synthase-2 (PGHS-2) of adult and fetal bovine endometrial epithelial cells in vitro. SAMPLE Primary cultures of endometrial epithelial cells obtained from 4 adult cows and 4 fetal bovine carcas...

For examining pig ovaries, which have complex structures, laparoscopy is a useful technique, but requires general anesthesia; therefore, it cannot be performed repeatedly within a short period of time. We report a transvaginal endoscopy-based technique for conducting ovarian examinations without general anesthesia. Sows were sedated in pig stalls. Using a colonoscope, the vaginal wall was punct...

Pudendal nerve entrapment (Alcock canal syndrome) is an uncommon source of chronic pelvic pain, in which the pudendal nerve is entrapped or compressed. Pain is located in the perineal, genital and perianal areas and is worsened by sitting. By simple entrapment of the PN without neurogenic damages, pain is usually isolated. In neurogenic damages to the PN, genito-anal numbness, fecal and/or urin...

In this project, we focus on building a prostate palpation simulator where a practitioner teaches his/herself a process called Digital Rectal Examination (DRE). While conventional mock-up-based training simulators can only provide a fixed number of abnormal conditions, our simulator is capable of creating various prostate abnormalities ranged from a single small tumor to multiple larger tumors,...
