Performing various perceptual actions elicits differentiable P300 responses.

Several studies have explored the differentiation of visual action verbs (e.g., see, perceive, and notice).

Twin pregnancy experimental model for transvaginal ultrasound-guided twin reduction in mares.

Multiple pregnancies are still an important cause of noninfectious abortion, stillbirth, neonatal mortality, and significant delays in reproductive performance in mares. Despite new management techniques, reduction in multiple pregnancies is an ongoing preoccupation and challenge for the equine veterinarian. The aim of the present study was to establish a twin pregnancy experimental model in the mare to study the effectiveness of a transvaginal ultrasound-guided embryonic vesicle injection.

Clinical diagnosis of uterine didelphia in Ayrshire heifer.

A 24-month-old Ayrshire heifer was referred because of infertility. A clinical diagnosis of uterus didelphys was established after a complete genital examination before the animal was culled from the herd.

Ovarian teratoma and endometritis in a mare.

An 8-year-old Arabian mare was admitted for a large ovarian anovulatory follicle. A clinical diagnosis of ovarian tumor and endometritis was established. Histological examinations revealed an ovarian teratoma and a grade II endometritis.

Idiopathic prolapse of 1 uterine horn in a yearling filly.

A yearling filly was presented for protrusion of a mass at the vulvar margins. A diagnosis of prolapse of the right uterine horn was made after vaginoscopy, transrectal palpation, and ultrasonography. It was confirmed later by biopsy of the tissue.

Hemoperitoneum caused by the rupture of a granulosa cell tumor in a Holstein heifer.

A case of a hemoperitoneum caused by the rupture of a granulosa cell tumor in a 9-month-old Holstein heifer is reported. Management of hemorrhagic shock in cattle is discussed.

Novel purification method for mammalian seminal plasma phospholipid-binding proteins reveals the presence of a novel member of this family of protein in stallion seminal fluid.

A family of bull seminal plasma (BSP) phospholipid-binding proteins (BSP proteins), potentiate heparin- and HDL-induced capacitation. The homologous proteins have been purified from stallion and boar seminal plasma, and detected in low concentrations in other mammalian seminal plasma. In this study, we developed a new isolation method for mammalian seminal plasma choline phospholipid-binding proteins wherein they are present in low concentrations.

Expression of key prostaglandin synthases in equine endometrium during late diestrus and early pregnancy.

Luteolysis in domestic species is mediated by the release of luteolytic pulses of prostaglandin (PG) F(2alpha) by the uterus at the end of diestrus, which must be suppressed by the conceptus to permit maternal recognition of pregnancy. In many species, including the horse, both the conceptus and the endometrium also synthesize PGE(2), which may antagonize PGF(2alpha) by playing a luteotropic and/or antiluteolytic role. While the release of PGE(2) and PGF(2alpha) by the equine endometrium in late diestrus and early pregnancy has been previously studied, the underlying prostaglandin synthase gene regulatory mechanisms remain poorly defined.
