In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total ce...

Vibrio cholerae, the cause of cholera, has two circular chromosomes. The parAB genes on each V. cholerae chromosome act to control chromosome segregation in a replicon-specific fashion. The chromosome I (ChrI) parAB genes (parAB1) govern the localization of the origin region of ChrI, while the chromosome II (ChrII) parAB genes (parAB2) control the segregation of ChrII. In addition to ParA and P...

PURPOSE To define the variations of the courses of the cranial nerves and the inferior petrosal sinuses as they enter and traverse the jugular foramen. METHODS Thirty-nine cadaveric specimens containing the jugular foramen were scanned with 1-mm contiguous axial and coronal CT sections. Each specimen was dissected to evaluate the position of the cranial nerves and inferior petrosal sinus as t...

We have recently identified two functional subregions in the frontal eye field (FEF) of the Cebus monkey, a smooth eye movement subregion (FEFsem) and a saccadic subregion (FEFsac). The thalamic input to these two subregions was studied and quantified to gain more information about the influence of the cerebellum and basal ganglia on the oculomotor control mechanisms of the cerebral cortex. A r...

In this issue, Sevigny and colleagues demonstrate that a protease-activated receptor (PAR)1–PAR2 heterodimer regulates vascular smooth muscle cell (VSMC) hyperplasia following vascular injury.1 PARs belong to a family of G-protein coupled receptors that are proteolytically activated by a variety of proteases.2,3 Cleavage of PARs results in intracellular signaling mediated by activation of vario...

Urban computing systems impact quality of life in densely populated areas. With the widespread availability of wireless networks and portable devices, urban areas are fast becoming a hybrid of the physical environment and the digital datasphere. This paper describes Yasmine’s Adventures, a location aware storytelling platform that leverages on urban computing strategies to create an interactive...

Vertebrate fossils have been collected for hundreds of years and are stored in museum collections around the world. These remains provide a readily available resource to search for preserved proteins; however, the vast majority of palaeoproteomic studies have focused on relatively recently collected bones with a well-known handling history. Here, we characterize proteins from the nasal turbinat...

abstract         background and objective: the current challenge of diabetes mellitus is to prevent its complications. these complications are directly associated with hyperglycemia in diabetics. the hba1c measurement is essential for long-term glycemic control. synchronization of hba1c measurement is important in order to avoid discrepancies between results reported by laboratories. this study...
