We compared male-reproductive-tract polypeptides of Drosophila melanogaster and D. simulans by using two-dimensional gel electrophoresis. Approximately 64% of male-reproductive-tract polypeptides were identical between two randomly chosen isofemale lines from these two species, compared with 83% identity for third-instar imaginal wing-disc polypeptides. Qualitatively similar differences were fo...
The olfactory tract in crucian carp (Carassius carassius) is divided into three distinct bundles: the lateral tract (LOT) and the lateral (lMOT) and medial (mMOT) bundles of the medial tract. The LOT has been shown to mediate information associated with feeding behavior, whereas the mMOT mediates information associated with alarm response. The role of the medial olfactory tract (lMOT and mMOT) ...
Clusterin is a 75-80 kDa heterodimenc glycoprotein that was first identified as a component of the fluid from the ram rete testes (Fritz et al, 1983). Over the past 15 years, the protein has been purified, or its cognate mRNA cloned, from a number of different species and diverse tissues, including several tissues of the reproductive tract (see Table 1). The role, or, more probably, roles, of t...
Caprine arthritis encephalitis is a worldwide, multisystemic disease caused by a small ruminant lentivirus. Although the main route of transmission is oral, detection of proviral DNA of the caprine arthritis encephalitis virus (CAEV) in caprine semen has been previously described. However, the presence of viral antigens in the male reproductive tract has apparently never been reported. The obje...
Estrogen is synthesized in the male reproductive system and is found in high concentrations in rete testis and seminal fluids. This luminal estrogen targets estrogen receptors (ER) along the male reproductive tract, and in particular the efferent ductules, where ERalpha is abundant. However, both ERalpha and ERbeta are found in various regions of the male reproductive tract. The transgenic ER k...
Infertility is an uncommon manifestation of genitourinary tract tuberculosis. Anatomic obstruction by granulomas or distortion of the normal anatomy by fibrosis surrounding the reproductive tract structures is the commonest cause of infertility. The diagnosis is usually based on a suggestive history along with evidence of granulomatous infection on a tissue sample. The management depends on the...
