We tested the winter immunity enhancement hypothesis(WIEH)on male desert hamsters(Phodopus roborovskii)kept under long-day(LD)and short-day(SD)*** assumed that under SD in a laboratory,the adaptive humoral immune responsiveness to the antigenic challenge would be enhanced due to the lack of winter physical stressors and food shortages and/or because of the action of an endogenous winter bolstering mechanism,while under LD the immune responsiveness would be suppressed by the activity of the reproductive *** results support the WIEH in *** did not find a difference in antibody production in response to sheep erythrocytes between SD and LD hamsters,but SD males had the lower number of granulocytes and the higher number of lymphocytes in white blood cell *** activity was lower in SD *** males demonstrated an increase in their mass-specific resting metabolic rate,their mass-specific maximal metabolic rate and their level of *** result of a generalized linear model analysis indicates the negative effect on secondary immunoresponsiveness to sheep erythrocytes of mid-ventral gland size,the organ characterizing individual reproductive quality,and designates a tradeoff between antibody production and reproductive *** mass-independent maximal metabolic rate also negatively affected antibody production,indicating a tradeoff between maximal aerobic performance and the adaptive immune *** higher stress in SD males seems to be the most likely reason for the lack of the effect of daylight duration on antibody production.

作者： Elizaveta v.Batishcheva Nikolay N.Smirnov Natalya v.Bobrova Maria P.sokolova Michael A.Smirnov Institute of Macromolecular Compounds Russian Academy of SciencesBolshoy pr.31Saint Petersburg 199004Russia

Green method for preparation of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CNF) modified by a copolymer of sodium acrylate and 2-acrylamido-2-methylpropanesulfonic acid was elaborated. FTIR and NMR data confirmed grafting of polyacrylate onto cellulose surface. Formation of porous structure of the ICM was controlled by SEM and AFM. The maximal ionic conductivity of the membranes reaches 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relative humidity) when they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,respectively. Prepared ICM was tested as a separator in a symmetrical supercapacitor with electrodes based on polyaniline hydrogel. The assembled cell demonstrate ability to operate at high current density up to 100 A·g^(-1) maintaining specific capacitance 165 F·g^(-1). Maximal specific capacitance of 289 F·g^(-1) was achieved at current density 1 A·g^(-1). Retaining of 90% of initial capacitance after 10000 of charge-discharge cycles proves high electrochemical stability of prepared ICM.
