Cattle are a major reservoir of Escherichia coli 0157:H7, an important zoonotic pathogen that causes hemorrhagic colitis and hemolytic uremic syndrome (HUS). Colonization of cattle occurs predominantly in the large intestine, and may especially target follicle-associated epithelium (FAE) in the terminal rectum. Bacterial colonization involves induction of attaching-effacing (A/E) lesions, media...

The effects of progesterone therapy (5 mg, administered subcutaneously daily for 6 days) on the abnormal uterus of adult anovulatory Wistar rats have been studied. These rats, rendered anovulatory by neonatal treatment with testosterone propionate or clomiphene citrate, displayed severe hyperplasia and metaplasia of the uterine luminal epithelium and a disproportionately high content of nuclear...

introduction: the effect of severe soft tissue injury on the severity of hemorrhagic shock is still unknown. therefore, the present study was aimed to determine hemodynamic and metabolic changes in traumatic/hemorrhagic shock in an animal model. methods: forty male rats were randomly divided into 4 equal groups including sham, hemorrhagic shock, soft tissue injury, and hemorrhagic shock + soft ...

Puberty: For the gilt and filly, the first corpus luteum (CL) appears to have a normal lifespan. For both species, first CL usually is associated with estrus but can form in the absence of estrus. For the ewe and cow, a transient (1 to 4 d, ewe; 3 to 10 d, cow) rise and fall of ovarian derived progesterone (P4) is detected in peripheral blood (80% of ewes; 50% of heifers) prior to first "normal...

Ovarian pregnancy is a rare form of ectopic pregnancy but it is the most common type of nontubal ectopic pregnancy. Many times it is operated with a misdiagnosis of ruptured tubal ectopic pregnancy or hemorrhagic corpus luteum. The high resolution transvaginal ultrasonography is a valuable tool for diagnosis of ectopic pregnancy but ovarian pregnancy still remains a diagnostic problem and a con...

BACKGROUND Gonadotropins are used in ovulation induction (OI) for patients with anovulatory infertility. Pharmacologic OI is associated with risks of ovarian hyperstimulation syndrome and multiple pregnancy. Treatment protocols that minimize these risks by promoting monofollicular development are required. A starting dose of 37.5 IU/day follitropin alfa has been used in OI, particularly among w...

background: anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (cvt). however, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician. methods: this was a prospective observational study on consecutive cvt patients with hemorrhagic venous infarction or subarachnoid hemorrha...

STUDY QUESTION Does serum anti-Müllerian hormone (AMH) vary significantly throughout both ovulatory and sporadic anovulatory menstrual cycles in healthy premenopausal women? SUMMARY ANSWER Serum AMH levels vary statistically significantly across the menstrual cycle in both ovulatory and sporadic anovulatory cycles of healthy eumenorrheic women. WHAT IS KNOWN ALREADY Studies to date evaluati...
