An indirect immunodot assay with rabbit antibodies raised against purified heat-stable enterotoxin type b (STb) and with a Western blotting (immunoblotting) detection system (ECL; Amersham International plc, Amersham, United Kingdom) was developed for the detection of STb toxin. Culture supernatants of 62 Escherichia coli isolates from pigs with diarrhea were blotted onto nitrocellulose and inc...

There are at least two classes of Escherichia coli heat-stable enterotoxins, STa and STb. Unlike STa, which is active in suckling mice and piglets, STb is inactive in suckling mice but active in piglets and older, weaned pigs. This study examined the activity of STb in several animals and its effect on intestinal histology and cyclic GMP levels in intestinal mucosal cells. STb did not cause flu...

bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...

Super liquid-repellent layers need to have a high impalement pressure and high contact angles, in particular a high apparent receding contact angle. Here, we demonstrate that to achieve both, the features constituting the layer should be as small as possible. Therefore, two models for super liquid-repellent layers are theoretically analyzed: A superhydrophobic layer consisting of an array of cy...

2 microns DNA isolated from industrial Saccharomyces cerevisiae yeasts exhibited extensive restriction fragment length polymorphisms. At least five 2 microns species were identified from eleven [cir+] strains. Southern hybridization mapped restriction fragment length polymorphisms at STB, a cis-acting locus essential for plasmid partitioning. Some 2 microns variants (e.g., 4110-2 microns and 41...
