atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...

We introduce the rank-sensitive priority queue — a data structure that always knows the minimum element it contains, for which insertion and deletion take O(log(n/r)) time, with n being the number of elements in the structure, and r being the rank of the element being inserted or deleted (r = 1 for the minimum, r = n for the maximum). We show how several elegant implementations of rank-sensitiv...

a total of 711 beta-hemolytic streptococci were isolated from throat cultures of patients during 1970-73. these strains were grouped in parallel by the precipitin and bacitracin paper disk method. the former method was estab­lished as the standard by which the bacitracin technique was compared. the difference in results was about 5.67%. the greatest error (5.4%) was seen with non-group a strain...

INTRODUCTION In a previous paper it was shown that the practice of storing time-sensitive chemicals for extended periods is dangerous. As one reviews the literature, one observes more and more cases of time-sensitive chemicals being stored for prolonged periods. Sometimes these chemicals are also improperly stored. Questions that come up include how time-sensitive chemicals are identified, what...

aim and background: discovering factors associated with mental health of the elderly is an interesting subject in the psychology of aging. this study investigated the relationships of spiritual well-being, existential well-being, and hardiness with mental health in the elderly. methods and materials: this descriptive-correlational research was conducted on the elderly living in the nursing home...

Assays for two distinct phosphatidate phosphohydrolase activities were established based upon a differential inhibition by N-ethylmaleimide (NEM). The activity that is insensitive to this reagent in rat liver is predominantly in the plasma membrane fraction, whereas the NEM-sensitive activity is in the cytosolic and microsomal fractions. The NEM-insensitive activity is further distinguished fro...

Nowadays Fault Injection is the main threat for any sensitive applications being executed on embedded devices. Indeed, such an attack allows one to efficiently recover any secret or to gain unauthorized privileges if no appropriate countermeasure is implemented. In the context of Java Card applications, the main method to counteract Fault Injection consists in adding redundancy for sensitive op...
