Four methods for the detection of Trichomonas vaginalis in vaginal secretions from 88 symptomatic patients were compared: wet-mount examination, Kupferberg liquid medium, Hirsch charcoal agar, and the Papanicolaou smear. Hirsch diphasic slants and Kupferberg medium did not significantly differ in sensitivity from direct examination of wet mounts. The Papanicolaou smear identification of trichom...

The quality defect ‘pale, soft, exudative’ (PSE) pork is caused by an acute stress response of the pig preslaughter and is estimated to cost the Australian pig industry in excess of $20 million per year. Dietary tryptophan has been reported to reduce the stress response of horses to trucking and to alleviate laying hysteria in hens. This preliminary experiment investigated the influence of exce...

Spring-calving, crossbred (1/4 to 3/8 Brahman) primiparous (n = 56) and multiparous (n = 102) beef cows were used to evaluate the effects of progesterone, delivered via a controlled internal drug-releasing (CIDR) device, and prostaglandin F(2alpha) (PGF(2alpha)) on estrous behavior, synchronization rate, initiation of estrous cycles, and pregnancy rate during a 2-yr period. To determine luteal ...

PURPOSE The subretinal layer between apical retinal pigment epithelium (RPE) and the apices of the photoreceptor outer segments is important to aging and degenerative pathogenesis, but current protocols do not provide intact horizontal images of this retinal space. Thus, an RPE/retina whole mount staining protocol was developed to observe integral subretinal regions. METHODS RPE/retina whole ...

Rubber engine mounts are commonly used to provide vibration attenuation. The loss factor and dynamic stiffness of engine mount provide fundamental information of the energy dissipation. The objectives of this work are to study the frequency-dependant stiffness and loss factor of engine rubber mount and to determine the effect of the orientation angle of the engine mount on the dynamic character...

The retinas of certain catfish contain multiple optic discs. This report describes the patterns of optic nerve fibers and optic discs as seen in silver-stained flat mounts, in 11 different families of catfish. As many as 50 optic discs may exist in a single retina, in paired and unpaired combinations, and in slit and ring-like arrays.
