The protective antigen (PA) moiety of anthrax toxin forms oligomeric pores in the endosomal membrane, which translocate the effector proteins of the toxin to the cytosol. Effector proteins bind to oligomeric PA via their respective N-terminal domains and undergo N- to C-terminal translocation through the pore. Earlier we reported that a tract of basic amino acids fused to the N-terminus of an u...
The use of acoustic energy to secure apple cider safety was explored. Inactivation tests were performed with Escherichia coli K12 at 40 °C, 45 °C, 50 °C, 55 °C, and 60 °C with and without ultrasound, followed by a validation test with E. coli O157:H7 at 60 °C. The cell morphology was observed with environmental scanning electron microscopy for samples treated at 40 °C and 60 °C. Physical qualit...
STUDY QUESTION How are ovarian steroid concentrations, gonadotrophins and menstrual cycle characteristics inter-related within normal menstrual cycles? SUMMARY ANSWER Within cycles, measures of estradiol production are highly related to one another, as are measures of progesterone production; however, the two hormones also show some independence from one another, and measures of cycle length ...
Microbial growth on mixtures of substrates is of considerable engineering and biological interest. Most of the work until now has dealt with microbial growth on binary mixtures of sugars or polyols. In these cases, it is often found that no matter how the inoculum is precultured, only one of the two substrates is consumed in the first growth phase, leading to the diauxic growth pattern. The goa...
سابقه و هدف: اشریشیاکلی یوروپاتوژنیک یکی از مهمترین عوامل ایجادکننده عفونت مجاری ادراری است. این سویهها انواع مختلفی از فاکتورهای ویرولانس از جمله چسبندهها، توکسینها و سیستمهای اکتساب آهن را دارا میباشند. ژنهای ویرولانس روی عناصر ژنتیکی متحرک و یا در نواحی خاصی از کروموزوم که جزایر پاتوژنیسیتی نامیده میشوند، قرار دارند. هدف از این مطالعه بررسی شیوع اشریشیاکلی یوروپاتوژنیک و فاکتورهای ویر...
in the united states schools in the k12 school system, that provide education for primary, junior and senior high school students, are moving toward information systems to solve and automate some manual processes performed in these schools. with this movement, and the pressure on schools to use technology to improve student achievement, many schools are turning to learning management systems as...
The primary technique currently used to detect biological agents is based on immunoassays. Although sensitive and specific, currently employed immunoassays generally rely on the detection of a single epitope, and therefore often cannot discriminate subtle strain-specific differences. Since DNA microarrays can hybridize hundreds to thousands of genomic targets simultaneously and do not rely on p...
