in order to evaluate the effects of phenytoin on the reproductive system of rats in detail, 60 male rats were divided equally into 6 groups: 1-5 received 10 mg/kg/day phenytoin ip for 1,2,3,4 and 5 weeks, respectively. however, group 5 did not receive any phenytoin for the last 5th week. the control group (group 6) did not receive any treatment. the results revealed that phenytoin does not have...

PURPOSE To evaluate the prevalence and type distribution of high-risk human papillomavirus (HPV) infection in genital warts of Korean men, and for the first time, to describe the risk factors associated with high-risk HPV infection in male genital warts. MATERIALS AND METHODS In a single private clinic, 150 consecutive male patients with histopathologic-confirmed genital warts who underwent H...

The development of Drosophila imaginal discs to a large extent depends on the genetic interactions that take place at the border between anterior (A) and posterior (P) cells. These two populations of cells differ as the selector gene engrailed (en) is expressed in P cells but not in A cells. The limit between A and P cells is the compartment border and acts as a source of positional information...

The present note aims to describe two alternative methods for observing genitalia in Lepidoptera. The first one provides means to examine both male and female genitalia without spoiling the scales of the abdomen, preserving it attached to the thorax and aesthetically similar to an unexamined specimen. The second one provides ways of observing certain characters on the male genitalia in a non-de...

A new species of dwarfgoby, Eviota piperata is described from Palau. It belongs to the cephalic sensory-pore system Group II (lacking only the IT pore); has a dorsal/anal-fin formula of 8/8; has some pectoral-fin rays branched; no dark spot over the ural centrum; the male genital papilla is not fimbriate; and the cheek and body are heavily peppered with chromatophores.

Megalota Diakonoff, 1966 is reported from China for the first time. Two new species, M. bicepsunca, sp. nov., and M., curvativa, sp. nov., are described and illustrated based on the male adults, both of them are distributed in south China Photographs of the adults and male genitalia are provided.

We characterized the evolution of simian immunodeficiency virus (SIV) in the male genital tract by examining blood- and semen-associated virus from experimentally and sham vaccinated rhesus monkeys during primary infection. At the time of peak virus replication, SIV sequences were intermixed between the blood and semen supporting a scenario of high-level virus "spillover" into the male genital ...

The six species of the genus Andraca Walker hitherto known from China are reviewed, and a new species, Andraca gongshanensis, sp. n., described from Yunnan Province, China. Adults and male genitalia of all examined species are illustrated, together with a distributional map. A key to all seven Chinese Andraca species is provided. The types of the new species are deposited in SCAU (South China A...

The validity of the Horaana strain of the Culex pipiens group as Cx. pipiens pallens was studied. Judging from the fourth instar characters and morphology of the adult male genitalia, this laboratory strain is now out of the range of ordinary Cx.p. pallens in Japan, and must be identified as Cx. p. quinquefasciatus.
