MSC from the young rats were characterized by a faster growth than adult MSC, correlating with levels of proliferating cell nuclear antigen (PCNA). However, there were no differences in respiratory activity of MSC from young and old rats, but young cells showed much higher glucose utilization than old ones. Autophagy flux was almost the same in both types of cells, but there were remarkable ultrastructural differences in old and young cells.Human response to wildlife management is widespread, encompassing both human-wildlife conflicts and wildlife conservation, in different places and at different times. As people become increasingly aware of the importance of wildlife to biological and environmental sustainability, newspapers can be important sources of information, especially in developing countries, such as Iran. Three major Iranian daily newspapers were analysed for news items related to wildlife. Over the 7-year study period, 434 articles presented environmental news, of which 61 items referred to wildlife. Each wildlife item was recorded in terms of message, contributor, spatiality, and allocated space. Structure query language (SQL) was used to analyse relationships between the 915 fields/entries. Wildlife items were characterised by public awareness (51%), columnist contributions (46%), and local spatiality (43%). Most items (82%) were allocated space of less than half a page. Of the categorised topics, those of combined endangered land (30%) and marine (5%) species exceeded items on global conservation (24%). Results highlighted the minimal number and small space devoted to wildlife news items and their concentrations (67%) in one of the three sampled newspapers. Although nature has historically been important in Iranian culture, current attitudes to wildlife, as reflected in newspaper coverage, do not seem to mirror these traditional perspectives. Given the widespread distribution of newspapers and their roles (i.e., as sources of information and opinion influencers), global wildlife conservation issues would benefit from much greater coverage in the daily press.Active commuting to school in children and adolescents can help achieve compliance with the World Health Organization (WHO) recommendations for physical activity. This study aimed to evaluate the relationship between the mode of transport used to go to school and the mode of transport used to go to extracurricular sports practice. Multistage random cluster sampling was conducted to include 128 schools with the participation of 11,017 students between the ages of 5 and 19. Participants completed the survey of sports habits designed by the National Sports Council. The results revealed that the mode of transport used to go to school is significantly related to the mode of transport used to go to sports practice. A total of 54.3% of students aged 5 to 19 years walk to school. A total of 23.7% of boys walk and 7.9% bike to extracurricular physical activities vs. 24.1% of girls who walk. The fact that girls only walk to extracurricular physical activities implies that the organized sports activities were nearby. Therefore, it seems crucial to have a wide range of physical activities on offer locally to promote extracurricular physical activity participation for girls.Since CD8+ T cells have immunological memory and can eliminate tumor or infected cells, antigen-specific CD8+ T cell inducing DNA vaccines are potential next-generation vaccines. However, the relationship between single amino acid deletion of target antigens in plasmid DNA vaccines and vaccine efficacy is not completely understood. To address this knowledge disparity and improve DNA vaccine development, two constructs cytosolic form of ovalbumin, pOVAv (346 amino acids) and pOVAy (345 amino acids) were constructed and compared. OVA proteins from both constructs were detected in an in vitro experiment. Then, the efficacy of prophylactic DNA vaccination using a gene gun against OVA-expressing mouse thymoma cells was compared. Both constructs conferred protection against tumor challenge, and there was no significant difference between the efficacies of pOVAv and pOVAy. The pOVAv vaccine induced stronger antigen-specific cytotoxicity in vivo, while bone marrow-derived dendritic cells (BMDCs) transfected with pOVAv induced higher levels of IFN-γ production from OT-I CD8+ T cells in vitro compared to pOVAy. These results indicate that a single amino acid deletion at N-terminus of the target antigen in a DNA vaccine leads to a different immunological outcome. The small modification of the target antigen in the DNA vaccine might improve its efficacy against tumor or infectious diseases.Aqueous zinc-polymer batteries (AZPBs) comprising abundant Zn metal anode and redox-active polymer (RAP) cathodes can be a promising solution for accomplishing viable, safe and sustainable energy storage systems. Though a limited number of RAPs have been successfully applied as organic cathodes in AZPBs, their macromolecular engineering towards improving electrochemical performance is rarely considered. In this study, we systematically compare performance of AZPB comprising Zn metal anode and either poly(catechol) homopolymer (named P(4VC)) or poly(catechol) copolymer (named P(4VC86-stat-SS14)) as polymer cathodes. click here Sulfonate anionic pendants in copolymer not only rendered lower activation energy and higher rate constant, but also conferred lower charge-transfer resistance, as well as facilitated Zn2+ mobility and less diffusion-controlled current responses compared to its homopolymer analogue. Consequently, the Zn||P(4VC86-stat-SS14) full-cell exhibits enhanced gravimetric (180 versus 120 mAh g-1 at 30 mg cm-2) and areal capacity (5.4 versus 3.6 mAh cm-2 at 30 mg cm-2) values, as well as superior rate capability both at room temperature (149 versus 105 mAh g-1 at 150 C) and at -35 °C (101 versus 35 mAh g-1 at 30 C) compared to Zn||P(4VC)100. This overall improved performance for Zn||P(4VC86-stat-SS14) is highly encouraging from the perspective applying macromolecular engineering strategies and paves the way for the design of advanced high-performance metal-organic batteries.
