The aim of this study was to test whether cholinergic mechanisms regulate dopamine (DA) release from the carotid body (CB) and interact with DA D(2) autoreceptors. One hundred forty-two CBs from adult rabbits were infused in vitro in a surviving medium bubbled with O(2) (Bairam A, Marchal F, Cottet-Emard JM, Basson H, Pequignot JM, Hascoet JM, and Lahiri S. J Appl Physiol 80: 20-24, 1996). CB D...

Sex differences in human sexuality are plentiful and include physical, psychological, and psychophysiological variations (Geary, 1998). Examples include masturbation frequency (Oliver & Hyde, 1993), sex drive (Baumeister et al., 2001), habituation of sexual arousal to sexual stimuli (Laan & Everaerd, 1995a, b; O’Donohue & Geer, 1985), cognition (Geer & Bellard, 1996), self-reported arousal to s...

Introduction. Women’s sexual dysfunction includes reduced interest/incentives for sexual engagement, difficulties with becoming subjectively and/or genitally aroused, difficulties in triggering desire during sexual engagement, orgasm disorder, and sexual pain. Aim. To update the recommendations published in 2004, from the 2nd International Consultation on Sexual Medicine (ICSM) pertaining to th...

Trichodinid Ciliophorans are one of the most common and widely dispersed groups of symbionts as parasites of aquatic invertebrate and vertebrate hosts (VAN AS & BASSON, 1989). The taxonomy of Trichodinids is based on the structure and the appearance of the adhesive disc and number and size of its constituents. All of these features can be revealed only by the silver impregnation technique of Kl...

The sexual pain disorders included in different editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R 1987; DSM-IV-TR, 2000) are dyspareunia and vaginismus. Both these clinical entities have undergone intense scrutiny and international discussion in the more recent years (Basson et Al 2003; Binik 2005; Graziottin, 2005; Meana et Al, 1997; Pukall et Al, 2005, Reissing ...

K. Bain S. Basson A. Faisman D. Kanevsky Accessibility in the workplace and in academic settings has increased dramatically for users with disabilities, driven by greater awareness, legislative mandate, and technological improvements. Gaps, however, remain. For persons who are deaf and hard of hearing in particular, full participation requires complete access to audio materials, both for live s...

Introduction The effects of mechanical force induced by fluid shear stress on the activity of several signal transduction pathways in endothelial cells is well documented (for a review, see Resnick and Gimbrone, Jr, 1995). Mechanical forces, such as those generated by fluid shear stress, are sensed at the cell surface (at adhesion points) by ␤1 and ␤3 integrins, and transduced through the cell ...

Silicomanganese (SiMn) is an alloy used in steelmaking to provide both Si and Mn additions at low carbon contents. In South Africa, SiMn is produced in three-phase alternating current (AC) submerged arc furnaces (SAFs) by carbothermic reduction of manganese ores in the form of lump, sinter, and briquettes (Steenkamp and Basson, 2013). In a SAF the electrode tips are submerged in a porous charge...

Paratrichodina Lom, 1963 comprises more than ten species. Paratrichodina has been found so far in various freshwater, marine fishes and amphibians worldwide. This report provides the first record of Paratrichodina from freshwater fishes in China. Smears with trichodinids were air-dried and then the slides with trichodinid ciliates were impregnated with Klein dry silver impregnation technique in...
