close-up, the flower buds of the weed Arabidopsis thaliana appear almost animal-like. The scanning electron micrographs above show a whole inflorescence (top right) and two individual flower buds in detail. The bud of a Columbia wild-type plant shown at bottom right has an oval shape and is tightly closed — as buds normally remain until the anther matures inside. By contrast, the bud on the lef...

Foodborne diseases occur worldwide, including those acquired through the consumption of contaminated meat. This study aimed to investigate the prevalence of enterotoxigenic Staphylococcus aureus, Salmonella and Escherichia coli pathotypes in different meat types. Forty meat samples fresh (n=35) and frozen (n=5) were purchased from local markets in Jenin district, Palestine. Multiplex PCR was us...

Precise removal of basal cell carcinomas (BCCs) with minimal damage to the surrounding normal skin is guided by the examination of frozen histology of each excision during Mohs surgery. The preparation of frozen histology is slow, requiring 20 to 45 min per excision. Confocal reflectance mosaicing may enable rapid detection of BCCs directly in surgical excisions, with minimal need for frozen hi...

Introduction Primary breeders are currently faced with the same problem plaguing most animal industries, rising production costs. Labor, feed and energy costs are forcing primary breeders to consider more economical ways of maintaining gene pools. One way to reduce such costs is with the use of frozen semen. With frozen semen available from superior sires, primary breeders will have the tool to...
