Introduction: The existence of a close relationship between energy status and reproductive function is well documented, but its underlying mechanisms remain to be fully unfolded.Galanin is an orexigenic agent and has been demonstrated as putative regulator of gonadotropin secretion in rats. There is no study to show the interaction of different levels of energy intake and galanin on gonadotropi...

This paper reviews some theoretical and computational aspects of plasma-wall interactions, in particidar the formation of sheaths. Some fundamental residts are derived analytically using a simple fluid model, and are subsequently tested with kinetic simulations. The various regions composing the plasma-wall transition (Debye sheath, colUsional and magnetic presheaths) are discussed in details.

introduction: previous studies have shown that ghrelin inhibits the activity of hypothalamus –pituitary – thyroid (h–p-t) axis. it is also proved that ghrelin increases appetite via agouti related protein and neuropeptide y pathway, decreases t3 & t4 secretion and inhibits serotonin release from hypothalamic synaptosomes. serotonin may interact with ghrelin in control of thyroid hormones secret...

patients and methods in total, 98 samples in four groups (hiv-positive and hiv-negative persons with and without oc) were obtained from the oral cavities and cultured on sabouraud’s dextrose agar and chromagar. also blood samples were obtained to assess plasma level of ifn-γ, il-4, il-6 and il-17 using elisa technique. background cell-mediated immunity (cmi) by cd4 + th (t helper)-type cells is...

We present a two-fluid plasma model to describe localized interaction, at submicrometer scale, of highly focused ultrashort laser pulses within dielectrics and semiconductors. This includes transport the electron-hole plasma, scattering, photoionization, impact ionization, interactions between charge carriers phonons. start with kinetic description, we consistently derive equations. Our numeric...

Objective(s): The purpose of this study was investigation of the protein corona formation on the surface of zwitterionic nanoparticles when they exposed to bio-fluid like human plasma.Methods: Silica nanoparticles with zwitterionic surface coating, cysteine and sulfobetaine were employed as zwitterionic ligands, were synthesized and characterized in terms of physicochemical properties. To...
