in asthmatic subjects there is a pronounced diurnal variation in bronchial responsiveness. if this phenomenon is due to variation in factors that control drug delivery, then it should be paralleled by a similar variation in competitive antagonist blockade. in order to study this possibility, we performed the methacholine challenge test and after 45 minutes, administered atropine by inhalation. ...

A quantitative trait locus (QTL) for uterine capacity is located on chromosome 8. Comparison of porcine and human genetic maps suggested that the estrogen sulfotransferase (STE) gene may be located near this region. The objectives of this study were to clone the full coding region for STE, compare endometrial STE gene expression between Meishan and White composite pigs during early pregnancy, a...

This paper describes the best method for automatic segmentation of Punjabi speech. Punjabi is one the most widely used language. Consequently, Punjabi is a syllabic language, so syllables are found to be the best units for the preparation of speech database. Further the automatic segmentation of speech is proved to be the better approach than the manual segmentation. The basic characteristics o...

this study identifies and compares the antecedent of nigerian students’ perception on business social responsibility. part of its objectives is to examine the perception of business students in terms of importance of business social responsibility with respect to profitability, and the effectiveness of social responsibility in both long and short terms. the study reviews the related literature ...

The purpose of this study was to determine whether dexamethasone attenuates the acute increase in macromolecular efflux from the oral mucosa elicited by an aqueous extract of smokeless tobacco (STE) in vivo, and, if so, whether this response is specific. Using intravital microscopy, we found that 20-min suffusion of STE elicited significant, concentration-related leaky site formation and an inc...

Enrichment is widely used as tool for managing fearfulness, undesirable behaviors, and stress in captive animals, and for studying exploration and personality. Inconsistencies in previous studies of physiological and behavioral responses to enrichment led us to hypothesize that enrichment and its removal are stressful environmental changes to which the hormone corticosterone and fearfulness, ac...

The mismatch between short lifetimes of free charge carriers and slow kinetics of surface redox reactions substantially limits the efficiency of most photocatalytic systems. Hence, the knowledge of trapping and recombination of photogenerated electrons and holes at different time scales is key for a rational optimization of photocatalytic materials. In this study, we used subsecond time-resolve...
