Centromere protein A (CENP-A) is a histone H3 variant that defines centromeric chromatin and essential for centromere function. In most eukaryotes, CENP-A-containing epigenetically maintained, identity inherited from one cell cycle to the next. germ line of holocentric nematode Caenorhabditis elegans , this inheritance disrupted. CENP-A removed at mitosis-to-meiosis transition reestablished on ...

Large, high-severity wildfires remove vegetation cover and expose mineral soil, ofen causing erosion and runoff during postfire rain events to increase dramatically. Land-management agencies in the United States are required to assess site conditions after wildfire and, where necessary, implement emergency watershed rehabilitation measures to help stabilize soil; control movement of water, sedi...

the study of the exclosure effects on the vegetation changes undergrazing and non-grazing conditions in the rangeland areas has particularimportance in the rangeland improvement and revivification projects. theresearch was accomplished in semi-steppe khoybilehvar area, from 1999 to2005. vegetation cover was annually measured within fixed plots during transact.the results showed that during nine...

This article proposes a framework of application-level security, an HW-SW implementation low-cost solution for real-time multimodal data encryption and decryption security applications in protected environments like espionage, situational awareness, monitoring, counter-UAV. Data is captured from drones equipped with microphone arrays cameras. performed by exploiting acoustic event analysis, vid...

background and purpose: otomycosis is an acute, subacute or chronic fungal infection of the pinna, the external auditory meatus and the ear canal caused mainly by several species of saprophytic fungi. lamisil (terbinafine) is an allylamine antifungal agent, that is used both in the topical and oral administration for the treatment of dermatophytosis, cutaneous candidiasis, and the pityriasis ve...

Grafts of fetal tissue including the suprachiasmatic nucleus (SCN) of the hypothalamus restore locomotor rhythmicity to behaviorally arrhythmic, SCN-lesioned Syrian hamsters. We sought to determine whether such transplants also reinstate endocrine rhythms in SCN-lesioned hamsters. In Exp 1, SCN lesions interrupted estrous cycles in a 14 h light, 10 h dark photoperiod and locomotor rhythms in co...

Physiologic drift of teeth requires remodeling alveolar bone at the tooth socket wall. Remodeling must be regulated so that collagenous attachments are maintained as new tooth positions are established. Thus, alveolar remodeling must occur coincident to remodeling of the Sharpey’s fibers which are embedded within that bone. Studies suggest that these fibers are severed at resorptive sites on th...

Because the circadian rhythms of oxygen consumption (VO(2)) and body temperature (T(b)) could be contributed to by differences in thermogenesis and because hypoxia depresses thermogenesis in its various forms, we tested the hypothesis that hypoxia blunts the normal daily oscillations in VO(2) and T(b). Adult rats were instrumented for measurements of T(b) and activity by telemetry; VO(2) was me...

Introduction to the Special Section This introduction outlines some of key ideas about migration and identity that multidisciplinary works in Korean studies this special issue delve into, focusing on a few great many migrations have taken place over last century continue do today. After contextualizing historically contemporary times, it explores concepts approaches should be considered fra...
