Somatosensory input to the hypothalamus has been thought to ascend via an indirect, multisynaptic pathway. However, we have antidromically identified nociceptive spinal cord neurons that project directly to the lateral hypothalamus in rats. Retrograde tracers injected into the lateral hypothalamus labeled many spinal neurons bilaterally within the marginal zone, the lateral reticulated area, th...
Background: Prenatal bacterial lipopolysaccharides (LPS) exposure causes damage of the brain and gonadal system.The aim of this study included determination of astaxanthin effect to ameliorate undesired effects of bacterial LPS during fetal period and improve maternal behavior, body weight and length and neural changes in adult male NMRI mice. Methods: Pregnant female mice were divided into fou...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
• The role of: the central nervous system in maintaining and modifying cardiac rhythmicity lias been extensively studied" by many investigators. Emphasis has been laid on the diencephalic region as a pathway for important neurovcgetative fibers. Pitts et al." showed that from both sides of the hypothalamus, multiple pathways descend, over which impulses converge on a single preganglioiiic sympa...
Immunoperoxidase technique and light microscopy have been used to localize neurosecretory systems for vasopressin, oxytocin and related neurophysins (neurohypophysial peptides)) and gonadotropin-releasing hormone (Gn-RH) in the rhesus monkey brain. All the neurohypophysial peptides were found in the magnocellular nuclei (suproptic and paraventricular) of the hypothalamus and in their projection...
Informations for the neural mechanism of pain sensation are still insufficient. Haugen and Melzack (1, 2) have shown that the afferent fibers most closely related to pain per ception caused by electrical stimulation of the tooth pulp project to the sensory cortex through the trigemino-bulbo-thalamic tract, but not via the trigeminal lemniscus. The significance of participation of the thalamic i...
The distribution of luteinizing hormone-releasing hormone (LH-RH)-immunostained cell bodies and fibres was studied in the brainstem and diencephalon of the cat using an indirect immunoperoxidase technique. The brainstem and the thalamus were devoid of immunostained cell bodies, whereas in the hypothalamus immunopositive perikarya were observed in the supraoptic nucleus, the anterior hypothalamu...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
