Oxidative and Endoplasmic Reticulum Stress Mediate Testicular Injury in a Rat Model of Varicocele.

Evidence of endoplasmic reticulum (ER) stress and activation of the unfolded protein response (UPR) have been increasingly reported in varicocele (VCL)-affected testes. However, the mechanisms by which oxidative stress (OS) and ER stress contribute to male infertility in VCL remain unclear. In this study, male Sprague-Dawley rats were divided into a control group, which underwent sham surgery, and a VCL group, in which VCL was surgically induced.

Academia's responses to crisis: A bibliometric analysis of literature on online learning in higher education during COVID-19.

This paper aimed to provide a holistic view of research that investigated online learning in higher education around the globe during COVID-19 utilizing a bibliometric analysis. The researchers used co-citation analysis and text mining afforded by VOSviewer to document and analyze research patterns and topics reported in peer-reviewed documents published between January 2020 and August 2021. Findings of this study indicated that scholars from 103 countries or regions from the Global North and Global South investigated a wide array of topics, such as use of various technologies and strategies, redesigned curriculum, student perceptions and psychological impacts of the pandemic-imposed online learning.

"Minimalist" Nanovaccine Constituted from Near Whole Antigen for Cancer Immunotherapy.

One of the major challenges in vaccine design has been the over dependence on incorporation of abundant adjuvants, which in fact is in violation of the "minimalist" principle. In the present study, a compact nanovaccine derived from a near whole antigen (up to 97 wt %) was developed. The nanovaccine structure was stabilized by free cysteines within each antigen (ovalbumin, OVA), which were tempospatially exposed and heat-driven to form an extensive intermolecular disulfide network.
