Lead intoxication in humans is characterized by cognitive impairments, particularly in the domain of memory, where evidence indicates that glutamatergic neurotransmission may be impacted. Animal and cell culture studies have shown that lead decreases the expression and activity of glutamine synthetase (GS) in astrocytes, yet the basis of this effect is uncertain. To investigate the mechanism re...

The corneas of New Zealand albino rabbits were isolated with a sclero-corneal rim for storage in a modified tissue culture medium (M-K medium) at 4° C. The corneas were either mounted in the specular microscope for daily observation of the endothelial layer and comeal thickness while being bathed in the storage medium at 4° C, or sealed in vials with the storage media. The vials were stored at ...

OBJECTIVE Urine is the most frequent specimen received for culture/sensitivity by clinical laboratories. The microbiological performance of HiCrome UTI agar medium was compared with Blood agar and MacConkey agar for isolation and presumptive identification of bacteria from urine culture. METHODS A total of 443 consecutively collected midstream and/or catheter-catch urine samples from patients...

Although the potential of marker-assisted selection (MAS) in fruit tree breeding has been reported, bi-parental QTL mapping before MAS has hindered the introduction of MAS to fruit tree breeding programs. Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. Selection based on genomic predictions of breeding values (genomic selection: GS)...

The common attribute of the geo–distributed systems (GS) is the way of their organization. The structure of GS is usually an up–down depended hierarchy where the processes of their inter work control are implemented as two sides (up–down, down–up) information exchange. As a result, the subcomponents of typical GS are in some distance from each other. The main clue of GS manager is the quality o...

PURPOSE To compare corneal endothelial cell function by measuring corneal thickness during temperature reversal between corneas stored in two different storage media, Optisol GS and Chen Medium (CM). METHODS Twenty paired corneas from 10 human donors were randomly assigned for storage at 4 degrees C in Optisol GS (10 corneas) or CM (10 corneas). The storage media were masked, and measurements...
