As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

In a recent paper published in cell,Xia et al.1 carried out 3D reconstructions of Blue Tongue Virus(BTV)particles and their assembly intermediates using a combination of cellular cryo-electron tomography(cryo-ET)and single-particle cryo-electron microscopy(cryo-EM).They were able to identify 11 structures,allowing them to refine our understanding of how double-stranded ribonucleic acid(dsRNA)viruses replicate in cells.

TAU is a neuronal microtubule-associated protein preferentially located in *** a battery of neurodegenerative diseases termed"tauopathies,"including Alzheimer's disease (AD),TAU is missorted and abnormally phosphorylated,leading to filamentous accumulations of hyperphosphorylated TAU,a pathological hallmark and potential disease driver of AD and related tauopathies (Zempel,2024).

AIM： To test the hypothesis that calcium sensing receptor （cASR） polymorphisms are associated with chronic pancreatitis （cP）, and to determine whether serine protease inhibitor Kazal 1type （SPINK1） N34S or alcohol are necessary co-factors in its etiology. METHODS： Initially, 115 subjects with pancreatitis and 66 controls were evaluated, of whom 57 patients and 21 controls were predetermined to carry the high-risk SPINK1 N34S polymorphism. We sequenced cASR gene exons 2, 3, 4, 5 and 7, areas containing the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 controls to analyze three common nonsynonymous single nucleotide polymorphisms （SNPs） in exon 7 （A986S, R990G, and Q1011E）. RESULTS： The cASR exon 7 R990G polyrnorphism was significantly associated with cP （OR, 2.01; 95% cI, 1.12-3.59; P = 0.015）. The association between cASR R990G and cP was stronger in subjects who reported moderate or heavy alcohol consumption （OR, 3.12; 95% cI, 1.14-9.13; P = 0.018）. There was no association between the various cASR genotypes and SPINK1 N34S in pancreatitis. None of the novel cASR polymorphisms reported from Germany and India was detected. cONcLUSION： Our United States-based study confirmed an association of cASR and cP and for the first time demonstrated that cASR R990G is a significant risk factor for cP. We also conclude that the risk of cP with cASR R990G is increased in subjects with moderate to heavy alcohol consumption.

Sperm function testing, once commonly performed for the infertile couple before employing assisted reproductive technology （ART）, has fallen out of favour in many reproductive medicine centers throughout the world. Indeed, the most recent addition of the ＇World Health Organisation （WHO） Laboratory Manual for the Examination and Processing of Hu- man Semen＇ now groups many of these procedures into a section termed Research Procedures. In large part, this reflects the current clinical practice of bypassing the in-depth evaluation of the male partner, while assuming that if a spermatozoon can be found for intracytoplasmic sperm injection （IcSI）, it must be a healthy cell capable of achieving fertilization. Never- theless, sperm function testing can provide valuable clinical insights into defects causing male infertility. Admittedly, in some cases, functional sperm deficiencies can be overcome using an ART. In other cases, couples will be empowered by the knowledge of the cause of their infertility, and for some couples, perhaps even the likelihood of IcSI success （relative to the spermatozoa）. The knowledge allows them to make truly informed reproductive decisions, including （perhaps） the de- cision to seek donor insemination, to adopt or to remain childless. Knowledge of the cause of their infertility may provide closure for couples and a sense of confidence regarding their choice of reproductive treatment.

Humanized mice are immunodeficient animals engrafted with human hematopoietic stem cells that give rise to various lineages of human blood cells throughout the life of the mouse. This article reviews recent advances in the generation of humanized mice, focusing on practical considerations. We discuss features of different immunodeficient recipient mouse strains, sources of human hematopoietic stem cells, advances in expansion and genetic modification of hematopoietic stem cells, and techniques to modulate the cytokine environment of recipient mice, in order to enhance reconstitution of specific human blood lineage cells. We highlight the opportunities created by new technologies and discuss practical considerations on how to make best use of the widening array of basic models for specific research applications.
