Dibromoacetic acid, a prevalent by-product of drinking water disinfection, compromises the synthesis of specific seminiferous tubule proteins following both in vivo and in vitro exposures

Autor: M, Holmes, J D, Suarez, N L, Roberts, M L, Mole, A S, Murr, G R, Klinefelter

Publikováno v: Journal of andrology. 22(5)

Dibromoacetic acid (DBA) is a by-product of drinking water disinfection that alters spermatogenesis in adult male rats. To identify a mechanism by which DBA alters spermatogenesis, seminiferous tubules representing specific groups of spermatogenic st

Fertility of rat epididymal sperm after chemically and surgically induced sympathectomy

Publikováno v: Biology of reproduction. 59(4)

Guanethidine, a chemical that selectively blocks sympathetic noradrenergic neurons, was used to investigate the role of sympathetic innervation in the fertility of rat epididymal sperm, using both natural mating and in utero insemination protocols. T

Rat epididymal sperm quantity, quality, and transit time after guanethidine-induced sympathectomy

Autor: W D, Kempinas, J D, Suarez, N L, Roberts, L, Strader, J, Ferrell, J M, Goldman, G R, Klinefelter

Publikováno v: Biology of reproduction. 59(4)

Guanethidine, a chemical that selectively abolishes peripheral noradrenergic nerves, was used to investigate the role of sympathetic innervation in the maintenance of epididymal sperm quantity and quality. Four groups of 10 adult male rats each were

SP22: a novel fertility protein from a highly conserved gene family

Autor: J E, Welch, R R, Barbee, N L, Roberts, J D, Suarez, G R, Klinefelter

Publikováno v: Journal of andrology. 19(4)

Three nucleotide sequences encoding SP22, a protein originally identified in detergent extracts of cauda epididymal sperm, were isolated from a rat testis cDNA library. While two of these cDNA sequences differed only in their 5' untranslated regions,

Discriminant analysis indicates a single sperm protein (SP22) is predictive of fertility following exposure to epididymal toxicants

Autor: G R, Klinefelter, J W, Laskey, J, Ferrell, J D, Suarez, N L, Roberts

Publikováno v: Journal of andrology. 18(2)

In a previous study, we found that ethane dimethanesulphonate (EDS) compromised the fertilizing ability of proximal cauda epididymal sperm from the rat within 4 days of exposure, an effect that persisted in castrated, testosterone (T)-implanted anima

Chloroethylmethanesulfonate-induced effects on the epididymis seem unrelated to altered Leydig cell function

Autor: G R, Klinefelter, J W, Laskey, W R, Kelce, J, Ferrell, N L, Roberts, J D, Suarez, V, Slott

Publikováno v: Biology of reproduction. 51(1)

Decades ago it was reported that when male rats were exposed to chloroethylmethanesulfonate (CEMS) for 5 days prior to weekly matings with untreated females, the second mating resulted in reduced litter size. Since fertility was not assessed at earli

Direct effects of ethane dimethanesulphonate on epididymal function in adult rats. An in vitro demonstration

Autor: G R, Klinefelter, N L, Roberts, J D, Suarez

Publikováno v: Journal of andrology. 13(5)

It was recently demonstrated that the Leydig cell toxicant ethane dimethanesulphonate (EDS) produces multiple effects on the epididymis after a single in vivo exposure. To determine whether any of the perturbations were mediated by a direct action of

That delicate balance: physician services within a multihospital system

Autor: D J, Lovasz, N L, Roberts

Publikováno v: Medical group management journal. 38(4)

Group practices and multihospital systems now are beginning to reap the benefits of centralized expertise, management and economies of scale, write Donald Lovasz and Nancy Roberts. These benefits, they warn, must be balanced with the entreprenurial s
