Abstract

Upon infection with an intracellular pathogen, cytotoxic CD8+ T cells develop diverse differentiation states characterized by function, localization, longevity, and the capacity for self-renewal. The program of differentiation is determined, in part, by FOXO1, a transcription factor known to integrate extrinsic input in order to specify survival, DNA repair, self-renewal, and proliferation. At issue is whether the state of T cell differentiation is specified by initial conditions of activation or is actively maintained. To study the spectrum of T cell differentiation, we have analyzed an infection with mouse cytomegalovirus, a persistent-latent virus that elicits different cytotoxic T cell responses characterized as acute resolving or inflationary. Our results show that FOXO1 is continuously required for all the phenotypic characteristics of memory-effector T cells such that with acute inactivation of the gene encoding FOXO1, T cells revert to a short-lived effector phenotype, exhibit reduced viability, and manifest characteristics of anergy.

Abstract

In this study, the catalytic activity of Cu-derived oxide catalysts in glycerol hydrogenolysis was investigated and the effect on the selectivity of 1,2-propanediol (1,2-PDO) with the different Cu/Al molar ratios was observed. The glycerol conversion/1,2-PDO selectivity was found to be dependent on the metallic sites and surface acidity of the Cu-based catalyst. The surface acidity and metallic sites of Cu nanoparticles were significantly improved with the increase of Cu/Al mole fraction in the catalyst. The efficiency of the Cu-derived oxide catalyst was attributed to the well-dispersed Cu and the presence of acidic sites. As expected, the Cu-based oxide catalyst (3CuAl) showed remarkable catalytic performance for 1,2-PDO synthesis with the highest turnover frequency (TOF) from the hydrogenolysis reaction. It is observed that the Cu-derived oxide catalyst is stable and efficient under strident reaction conditions in the presence of water and high temperature (aqueous glycerol solution (20 wt%), 210 °C, 40 bar). Moreover, the reaction conditions for glycerol hydrogenolysis in the presence of active 3CuAl were optimized to maximize the selectivity of 1,2-PDO with TOF. In addition, overcoming the limitation due to the external mass transfer resistance was investigated. The rate of glycerol consumption was subjected to kinetic analysis, which revealed a zero-order relationship on glycerol concentration, indicating that adsorbed glycerol was the most tightly bonded organic adsorbate. Further, the experimental reaction data was validated through the developed artificial neural network (ANN) model.

50. USE OF ELECTRONIC RESOURCES BY USERS OF THE GAUTAM BUDDHA CENTRAL LIBRARY AT THE B.B.A.U., LUCKNOW, UTTAR PRADESH: A STUDY

Author

dwivedi, suraj kumar, Verma, Shilpi, dwivedi, suraj kumar, and Verma, Shilpi

Abstract

Electronic resources are becoming increasingly popular as a result of their benefits and advantages. Libraries are subscribing to electronic resources for their users and spending a lot of money on it. It is vital to assess user attitudes regarding e-resources. This article investigates user knowledge and perceptions of e-resources accessible at the Gautam Buddha Central Library, BBAU, Lucknow. This study is an attempt to investigate user awareness of e-resources, user frequency of access to e-resources, user perception towards use of e- electronic, purpose of users to use it, problem encountered by users in accessing e-resources, its importance in study and research, and so on.
