OBJECTIVE Humans and animals exposed to undernutrition (UN) during development often experience accelerated "catch-up" growth when food supplies are plentiful. Little is known about the mechanisms regulating early growth rates. We previously reported that actions of leptin and presynaptic inputs to orexigenic NPY/AgRP/GABA (NAG) neurons in the arcuate nucleus of the hypothalamus are almost excl...

Cel: zasadniczym celem bada? by?o sprawdzenie, czy w obr?bie serwisów regionalnych jednej grupy medialnej (Agory SA) narracja na temat Ukrai?ców jest spójna, te? dostrzec mo?na niej jakie? odmienno?ci. Metody bada?: podstaw? metodologiczn? stanowi?a analiza zawarto?ci, która obj??a nag?ówki zapowiadaj?ce teksty o Ukrai?cach dwóch portalach „Gazety Wyborczej” – www.wroclaw.wyborcza.pl oraz www.r...

Nanotechnology has been advanced since the last decades. Among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. Its release into natural water bodies is inevitable due to its broad applications. Nanosilver (nAg) was prepared via Tollens method using. The morphology, size distribution and average size of the obtained nAg was characterized using Tr...

We consider a continuous-time optimization method based on dynamical system, where massive particle starting at rest moves in the conservative force field generated by objective function, without any kind of friction. formulate restart criterion mean dissipation kinetic energy, and we prove global convergence result for strongly-convex functions. Using Symplectic Euler discretization scheme, ob...

Correspondence to:Dr. Gãdãlean Florica, e-mail: [email protected] SUMMARY:Background Tubular adaptive changes occurring after 50% reduction of renal mass can, in time, cause lesion to the tubular cell. According to data in the literature, the adaptive mechanisms occuring in the surgically aquired single kidney (SK) compared to those occurring in the congenital single kidney, seem to be compl...

In order to argue effectively one must have a grasp of both the normative strength of the inferences that come into play and the effect that the proposed inferences will have on the audience. In this paper we describe a program, NAG (Nice Argument Generator), that attempts to generate arguments that are both persuasive and correct. To do so NAG incorporates two models: a normative model, for ju...

The possible production of a heat-stable enterotoxin (Vc-H-ST) by Vibrio cholerae non-O1 serogroup Hakata was investigated, and the purified Vc-H-ST was characterized. It has a unique amino acid sequence, LIDCCEICCNPACFGCLN. This sequence is quite similar to that of the heat-stable enterotoxin (NAG-ST) produced by V. cholerae non-O1 except for one amino acid (leucine) residue excess at the N te...
