The OMEGA architecture provides end-to-end quality of service (QoS) guarantees for distributed applications. QoS parameters are translated between application and network requirements by the QoS Broker, thus integrating media and network QoS management into a single entity. Admission control uses a schedulability test derived from application requirements. A novel task priority and precedence b...

1. The objective of the study was to compare the establishment and effect of Asaridia galli infections in 4 different layer-lines. 2. A total of 160 birds comprising 4 different commercial layer-lines, ISA Brown, New Hampshire, Skalborg and a cross of New Hampshire(NH) and Skalborg (Sk), were infected with A. galli eggs. The birds were examined for the presence of parasite eggs and parasites at...

In rodents, sexual behavior depends on the adequate detection of sexually relevant stimuli. The olfactory bulb (OB) is a region of the adult mammalian brain undergoing constant cell renewal by continuous integration of new granular and periglomerular neurons in the accessory (AOB) and main (MOB) olfactory bulbs. The proliferation, migration, survival, maturation, and integration of these new ce...

It has been shown that maternal hyperthyroidism can affects on neonatal outcomes such as spontaneous abortion, intrauterine growth retardation. The aim of this study was to investigate the influence of hyperthyroidism on formation of cerebellar cortical layers in the rat embryos. Thirty Sprague-Dawley female sexually mature rats weighting 200 ± 20 g were used in the study. Female rats were rand...

1.1 Anatomy of the lower urinary tract Initially, a brief summary of the anatomy of the lower urinary tract will be presented. The bladder is a hollow muscular organ in pelvis lined by a mucous membrane and covered on its outer aspect partly by peritoneal serosa and partly by fascia (Lich et al. 1978; Dixon and Gosling 1987). The muscularis of the bladder is formed of smooth muscle cells which ...

We mapped the cellular expression of estrogen receptor (ER) and ER mRNAs in the male reproductive system of the rat during development and adulthood by in situ hybridization. The expression patterns of ER mRNA in the gonad, efferent duct and initial segment of the epididymis during the perinatal period were essentially similar to those of the adult: ER mRNA signals were expressed most intensely...

Several proteins of Clostridium thermocellum possess a C-terminal triplicated sequence related to bacterial cell surface proteins. This sequence was named the SLH domain (for S-layer homology), and it was proposed that it might serve to anchor proteins to the cell surface (A. Lupas, H. Engelhardt, J. Peters, U. Santarius, S. Volker, and W. Baumeister, J. Bacteriol. 176:1224-1233, 1994). This hy...

Calcifying odontogenic cyst (COC) is an odontogenic cyst with accumulation of ghost cells that has central and peripheral subsets. Here, we present an 11-year-old male patient with an intraoral swelling on the left posterior mandibular ridge interfering with eruption of the second molar. Histopathologic examination revealed a cystic lesion lined by ameloblast-like epithelium in the basal layer ...

UNLABELLED The most common etiologies of tympanic membrane perforation are infections and trauma. OBJECTIVE The objective of the present study was to assess the healing of traumatic tympanic membrane perforation in rats. METHODS The tympanic membrane from male Wistar rats was perforated in the anterior and posterior portions to the handle of the malleus. Five tympanic membranes were evaluat...

We identified the Arabidopsis MALE STERILITY1 (MS1) gene by transposon-mediated mutagenesis. In the transposon-inserted allele ms1-8, normal immature microspores separated from tetrads, but their subsequent maturation was abnormal: the outer layer of the microspore was absent, and both the microspore and the tapetal layer gradually became vacuolated. Empty locules resulted. The MS1 gene was exp...
