Regulation of chromosome inheritance is essential to ensure proper transmission of genetic information. To accomplish accurate genome segregation, cells organize their chromosomes and actively separate them prior to cytokinesis. In Bacillus subtilis the Spo0J protein is required for accurate chromosome segregation and it regulates the developmental switch from vegetative growth to sporulation. ...

OBJECTIVE We analyzed the clinical and radiologic features of posterior apophyseal ring separation (PARS) with lumbar disc herniation and suggest the proper management options according to the PARS characteristics. METHODS We reviewed case series of patients with PARS who underwent surgery of lumbar disc herniation. Preoperative symptoms, neurologic status, Body Mass Index, preoperative and p...

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...

When the jelly-less eggs removed from the most cephalic region of the oviduct (pars recta) of the toad Bufo arenarum were inseminated at a high sperm concentration, high frequencies of fertilization were obtained. On the other hand, control eggs removed from the pleuroperitoneal cavity (coelomic eggs)) were neither fertilized upon insemination under identical conditions, nor with the water extr...

Numerous functional neuroimaging studies reported increased activity in the pars opercularis and the pars triangularis (Brodmann's areas 44 and 45) of the left hemisphere during the performance of linguistic tasks. The role of these areas in the right hemisphere in language processing is not understood and, although there is evidence from lesion studies that the right hemisphere is involved in ...

A numerical simulation for analysis and optimization of the performance NOx production was applied to a natural gas fuel boiler in South Pars Gas Complex. For this purpose, nine actual environmental operational parameters were measured recorded every two hours then averaged daily year. Using thermodynamic laws, important such as body exhaust flue losses, well thermal efficiency exergy efficienc...

Sir, We appreciate the opportunity to respond to the comment by Xiang et al. (2013) on our review on interspecies differences in the pedunculopontine nucleus area. As exemplified by the data of Xiang et al. (2013) it is evident that the mesencephalic locomotor region compromises several distinct structures that are involved in initiation and inhibition of gait, and certainly the implications of...

The gonadotropes, LH and FSH cells, were immunohistochemically identified in the pituitary pars distalis of the adult male viscacha (Lagostomus maximus maximus) using specific antibodies against hLHbeta and hFSHbeta with the streptavidin-biotin-peroxidase complex. The distribution, size and percentage immunopositive area of these cells were analyzed by image analysis in viscachas captured durin...

Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...

Proteinase-activated receptors (PARs) are a four-member family of G protein-coupled defined by their irreversible proteolytic mechanism activation. PARs have emerged as important regulators various physiological responses and implicated in numerous pathological conditions. Importantly, PAR1 PAR4 critical platelet function, while PAR2 is well established driver inflammatory responses. PAR-target...
