OBJECTIVE To determine the susceptibility pattern of extended spectrum ß-lactamase (ESBL) producing Gram negative isolates from various clinical specimens. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Microbiology Department, Armed Forces Institue of Pathology, Rawalpindi, from January 2008 to January 2009. METHODOLOGY A total of 308 ESBL producing isolates from various cli...
ß-Glucuronidase is the novel enzyme known to present in the tissues of several vertebrates. It can be detected by biochemical, histochemical and immunocytochemical techniques in bacteria, plant and animal. The traditional method used for histochemical demonstration of ß-glucuronidase is quite tedious and substrate utilized in a given concentration is not affordable to researchers of the develop...
In this note we prove a theorem concerning the two cardinal problem (see [l], [4], [6], [7] for reference and for some of the standard notation); this result has been referred to in [6, p. 311] and [7, (3.7) ]. The problem, first proposed by Vaught, is as follows. Let T be a first-order theory and let U be a unary predicate symbol in the language of T. T is said to admit the pair a, ß of cardin...
To further elucidate the possible involvement of intracellular protein catabolism in the development of insecticide resistance, we determined in vivo effect of the potent synthetic pyrethroid, ß-cyfluthrin on the activities of cytoplasmic and lysosomal proteolytic enzymes in insecticide-resistant and susceptible strain of housefly, Musca domestica. ß-Cyfluthrin at LC50 dose after 48 hour treatm...
Let F be a (topologically) finitely generated free pro-p-group, and ß an automorphism of F . If p ^ 2 and the order of ß is 2 , then there is some basis of F such that ß either fixes or inverts its elements. If p does not divide the order of ß , then the subgroup of F of all elements fixed by ß is (topologically) infinitely generated; however this is not always the case if p divides the order o...
مقدمه: این پژوهش با هدف بررسی نسبت روایی محتوایی و ارزیابی اعتبار سازه پرسشنامه انتظارات آموزشی از یکسو و از سوی دیگر بررسی نقش انتظارات اطرافیان بر تغییر نگرش نسبت به استفاده از محتوای درسی الکترونیکی انجام شده است. روش: روش پژوهش همبستگی و جامعه آماری آن دانشجویان دانشگاه‌های پیام نور فارس هستند برای تعیین حجم نمونه، از فرمول کرجسی و مورگان و روش نمونه‌گیری خوشه‌ای استفاده شده است. ابزار مورد...
The influence of ß-dihydroxyl groups in the alkaline hydrolysis of glucosidic bonds is examined. In deriva tives of ß-D-glucopyranosides, all hydroxyl groups are trans to each other, and the alkaline elimination of sub stituted methyl ethers in positions C-2 and C-4 can be explained, in part, by assistance from neighboring trans a-hydroxyls. The rate of degradation of ethyl 2-2-methyl-ß-D-glu...
BACKGROUND Nothing is known about the epidemiology and resistance mechanisms of extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-PE) in Burkina Faso. The objective of this study was to determine ESBL-PE prevalence and to characterize ESBL genes in Burkina Faso. METHODS During 2 months (June-July 2014), 1602 clinical samples were sent for bacteriologic investigations to the mic...
Background: Wet cupping therapy is a complementary therapy in pain management. The mechanism of this therapy, however, needs further elucidation. Cells injured by wet cupping therapy seem to stimulate the expression of heat shock protein 70 (HSP70). Its benefit in pain reduction could be mediated by the expression of ß-endorphin. This study aimed at determining the correlation between HSP70 and...
