We used the teleost Astyanax mexicanus to examine the role of the lens in optic nerve and tectum development. This species is unusually suited for studies of nervous system development and evolution because of its two extant forms: an eyed surface dwelling (surface fi sh) and several blind cave dwelling (cavefi sh) forms. Cavefi sh embryos initially form eye primordia, but the lens eventually d...

A s evidenced in Paleolithic cave paintings of fi sh dating from 17,000 years ago, human-fi sh interactions have existed for thousands of years (Valladas et al. 2001). The earliest interactions likely involved fi sh as food and were necessarily tied to geographic access (i.e., island or coastal locations). Over time, the establishment of farm fi shing and the emergence of modern capture and tra...

Studies of protein-bound (PB-SH) and nonprotein bound sulfhydryl group (NP-SH) concentrations in tissues under various conditions is a prerequisite to understanding the role of sulfhydryls in living organisms. Many methods have been developed for the measurement of sulfhydryl groups, but these have been concerned chiefly only with the estimation of NP-SH in biological fluids or total SH groups ...

Mumps virus (MuV), a rubulavirus of the paramyxovirus family, causes acute infections in humans. MuV has seven genes including a small hydrophobic (SH) gene, which encodes a type I membrane protein of 57 amino acid residues. The function of the SH protein is not clear, although its expression is not necessary for growth of MuV in tissue culture cells. It is speculated that MuV SH plays a role i...

PURPOSE Social isolation is associated with suicidal ideation (SI) and self-harm (SH) among adolescents. However, the association between preference for solitude (PfS), SI, and SH is unknown. The prevalence of adolescents who have both of PfS and social isolation and the risks for SI and SH among them are also unknown. METHODS Information on PfS, social isolation, SI, and SH was collected in ...

BACKGROUND It is notable that sitting height (SH) correlates with blood pressure (BP) in children and adolescents of developed countries. However, little is known about the relationships between SH and SH to height ratio (SH/H) with BP in South African children from middle and upper socio-economic groups. The purpose of this study was to compare SH and SH/H of private school attending children ...
