Neuronal activity in posterior cingulate cortex (CGp) is modulated by visual stimulation, saccades, and eye position, suggesting a role for this area in visuospatial transformations. The goal of this study was to determine whether neuronal responses in CGp are anchored to the eyes, head, or outside the body (allocentrically). To discriminate retinocentric from nonretinocentric spatial referenci...

The ras oncogene-encoded p21 protein is known to induce cell maturation of Xenopus laevis oocytes and malignant transformation of NIH 3T3 mouse fibroblasts. The pathways involved in oocytes and NIH 3T3 cells appear to be similar to one another. For example, in both cases, the ras p21-induced cellular events involve increased intracellular levels of the second messengers diacylglycerol and inosi...

Abnormal regulation of the renin angiotensin system such as enhanced renal AT1R function and reduced ACE2 activity contributes to obesity-related hypertension. Here, we tested whether long-term AT2R activation affects renal function in obesity using lean and obese Zucker rats treated with the AT2R agonist CGP42112A for 2 weeks. This caused blood pressure to decrease by 13 mm Hg, which was assoc...

The role of gamma-aminobutyric acid B (GABA(B)) receptors in the generation and maintenance of bicuculline-induced epileptiform activity in rat neocortical slices was studied using electrophysiological methods. A block of GABA(B) receptors in the presence of functional GABA(A) receptor-mediated inhibition was not sufficient to induce epileptiform activity. In the presence of the GABA(A) recepto...

Abstract Disturbances of GABAergic inhibition are a major cause of epileptic seizures. GABA exerts its actions via ionotropic GABAA receptors and metabotropic G protein-coupled GABAB receptors. Malfunction of GABAA inhibition has long been recognized in seizure genesis but the role of GABAB receptors in controlling seizure activity is still not well understood. Here, we examined the anticonvuls...

Background: Deficits in upper body movement have received little attention during gait in cerebral palsy (CP) children with crouch gait pattern (CGP).Objective: Purpose of this research is to describe the correlation of trunk movement with the excessive knee flexion and ankle kinematic in CP children with CGP.Methods: Gait analysis data from 57 limbs of diplegic CP children with CGP and 26 limb...

Boolean functions represent an important primitive when constructing many stream ciphers. Since they are often the only nonlinear element of such ciphers, without them the algorithm would be trivial to break. Therefore, it is not surprising there exist a substantial body of work on the methods of constructing Boolean functions. Among those methods, evolutionary computation (EC) techniques play ...

The purpose of the present study was to investigate the effects of competitive NMDA receptor antagonists,D,L-(E)-2-amino-4-methyl-5-phosphono-3-pentenoic acid (CGP 37849) and its ethyl ester (CGP 39551), or agonist, N-methyl-D-aspartate (NMDA) on spontaneous alternation in mice exposed to cerebral oligemia. Alternation behavior was evaluated in an Y-maze. Transient cerebral oligemic hypoxia was...

Pregnancy is associated with hemodynamic changes such as reduced vascular resistance and blood pressure. We reported that, during late pregnancy, the activity of voltage-dependent calcium channels (VDCC) is altered in the adrenal cortex and vascular smooth muscle. These observations suggested that the late pregnancy-induced decrease in blood pressure is linked to diminished VDCC function. We at...

Abstract Economic development in Sub Saharan African countries is strongly tied to households' ability cope with exogenous events affecting their well-being. Using data from the Lesotho Child Grant Program (CGP) we provide evidence on presence of any spillover effect program non-eligible households living treated villages and whether food security nutrition are influenced by a particular networ...
