For the past two decades,conversion and alloying-type materials have been heralded as the natural heir to commercially available graphite anodes due to their ability to deliver high gravimetric/volumetric power.Commercialization of batteries with these high-energy-density active materials could impact a variety of sectors including electric vehicles,grid storage,and consumer electronics and contribute toward an ever-increasing electrified world.However,the various failure mechanisms from inherent interfacial chemical instabilities associated with these materials make them unable to be merely substituted into currently available electrode fabrication and formulation processing techniques.As a result,realizing the high theoretical capacity and achieving commercial viability of these materials will rely on the careful manipulation of interfacial chemical interactions that dictate and control various kinetic and transport processes across multiple scales of the composite electrode.This has led to a plethora of research that has focused on systematically understanding properties of the different electrode components and designing carefully constructed electrode formulations to achieve composite electrodes with increased chemical stability,enhanced local mixed conductivities,or improved mechanical resilience.This Account relates recent progress in the understanding of synergetic opportunities for energy-dense,resilient composite anodes.By understanding the interplay between components of the composite electrode,we can construct enhanced well-integrated electrodes with performance metrics that surpass empirically derived architectures.Due to the increased complexity of high-volume-expanding electrodes,performance is more than the cumulative contributions of the individual components,and therefore energy and compatibility matching are important for robust electrochemical performance across cycling,rate capability,facile lithium-ion transport,and stability.In this Account,synergistic opportunities are framed from a chemis

Elastic,repairable and conductive fibers are desirable in the newly emerging field of soft electronic and wearable devices.Here,we design a multifunctional fiber by incorporation of different components to optimize its performance.The combination of the poly(acrylic acid)(PAA)and poly(ethylene oxide)(PEO)through hydrogen bonding endows the fiber with high elasticity and repairability.Polydopamine(PDA)significantly increases the stability of the fiber,thus the fiber will not dissolve in alkaline solutions and still keep the repairable ability.The fiber shows a reversible swelling-shrinking property as pH values go up and down.Further,the conductive component,carbon nanotube,is adsorbed at the swelling state and then is fastened with fiber shrinking.

Post-transcriptional mechanisms controlling neurogenesis and direct neuronal reprogramming

引用

Neural Regeneration Research 2024年第9期19卷 1929-1939页

作者： elsa Papadimitriou Dimitra Thomaidou Department of Neurobiology Hellenic Pasteur InstituteAthensGreece

Neurogenesis is a tightly regulated process in time and space both in the developing embryo and in adult neurogenic niches.A drastic change in the transcriptome and proteome of radial glial cells or neural stem cells towards the neuronal state is achieved due to sophisticated mechanisms of epigenetic,transcriptional,and post-transcriptional regulation.Understanding these neurogenic mechanisms is of major importance,not only for shedding light on very complex and crucial developmental processes,but also for the identification of putative reprogramming factors,that harbor hierarchically central regulatory roles in the course of neurogenesis and bare thus the capacity to drive direct reprogramming towards the neuronal fate.The major transcriptional programs that orchestrate the neurogenic process have been the focus of research for many years and key neurogenic transcription factors,as well as repressor complexes,have been identified and employed in direct reprogramming protocols to convert non-neuronal cells,into functional neurons.The post-transcriptional regulation of gene expression during nervous system development has emerged as another important and intricate regulatory layer,strongly contributing to the complexity of the mechanisms controlling neurogenesis and neuronal function.In particular,recent advances are highlighting the importance of specific RNA binding proteins that control major steps of mRNA life cycle during neurogenesis,such as alternative splicing,polyadenylation,stability,and translation.Apart from the RNA binding proteins,microRNAs,a class of small non-coding RNAs that block the translation of their target mRNAs,have also been shown to play crucial roles in all the stages of the neurogenic process,from neural stem/progenitor cell proliferation,neuronal differentiation and migration,to functional maturation.Here,we provide an overview of the most prominent post-transcriptional mechanisms mediated by RNA binding proteins and microRNAs during the neurogenic process,giving particular emphasis on

作者： Rebecca Y.M.Cheung Iris Yili Wang elsa Ngar-Sze Lau School of Psychology and Clinical Language Sciences University of ReadingReadingUK Department of Special Education and Counselling The Education University of Hong KongHong KongChina Department of Educational Administration and Policy The Chinese University of Hong KongHong KongChina

Guided by the theoretical processes of mindfulness and psychological well-being,this study examined serenity as a mediator between mindfulness facets and psychological well-being,as indexed by depressive symptoms and life satisfaction.Participants were 133 mindfulness practitioners who took part in a 3-day transnational meditation event in Hong Kong.Upon informed consent,participants completed a self-report questionnaire.The findings from structural equation modeling showed that serenity mediated the relation between two facets of mindfulness,including describing and nonreacting to inner experience,and life satisfaction.Serenity also mediated the relation between the mindfulness facet of describing and depressive symptoms.Direct associations were indicated between two mindfulness facets,including observing and nonjudging of inner experience,and depressive symptoms.Taken together,the findings revealed mindfulness facets as major correlates of serenity and psychological outcomes among Chinese meditation practitioners.To foster psychological well-being,researchers,educators,and practitioners should pay attention to the role of serenity,describing,and nonreacting to inner experience in mental health.

Effect of a Commercial Extract of Green Tea and a Pure Catechin on Two Veillonella strains

引用

Advances in Microbiology 2024年第6期14卷 340-350页

作者： Jorge A. Yáñez-Santos Vianey Lino-Aguilar elsa I. Castañeda-Roldan Jorge Giron Lilia Cedillo Centro de Deteccin Biomolecular Benemrita Universidad Autnoma de Puebla Puebla Mexico Facultad de Estomatologa Puebla Mexico

The catechin Epigallocatechin-3-O-Gallate (EGCG) which is found in of Green Tea extracts (GTE), displays a variety of microbicidal properties. It is largely believed that EGCG inhibits the growth of cariogenic and periodontopathic bacteria. Objective: In this paper we compared the inhibitory activity of EGCG and a commercial GTE on the growth of Veillonella parvula. Chlorhexidine was used as positive control. Methodology: V. parvula ATCC 10790 and a clinical isolate obtained from a periodontal disease patient were cultured in the presence of EGCG or a commercial GTE, and the measurements of bacterial growth inhibition were compared to the values obtained with 0.12 and 0.2% chlorhexidine. Results: Chlorhexidine inhibited bacterial growth, however in contrast to a previous report, neither EGCG nor the GTE showed any effect on bacterial growth. Conclusions: The data show and confirm that chlorhexidine is a growth inhibitor of V. parvula while EGCG and GTE do not display such effect.

Common psychiatric disorders(CPDs)and depression contribute significantly to the global epidemic of type 2 diabetes(T2D).We postulated a possible pathophysiological mechanism that through Bridge-Symptoms present in depression and CPDs,promotes the establishment of emotional eating,activation of the reward system,onset of overweight and obesity and,ultimately the increased risk of developing T2D.The plausibility of the proposed pathophysiological mechanism is supported by the mechanism of action of drugs such as naltrexonebupropion currently approved for the treatment of both obesity/overweight with T2D and as separate active pharmaceutical ingredients in drug addiction,but also from initial evidence that is emerging regarding glucagon-like peptide 1 receptor agonists that appear to be effective in the treatment of drug addiction.We hope that our hypothesis may be useful in interpreting the higher prevalence of CPDs and depression in patients with T2D compared with the general population and may help refine the integrated psychiatric-diabetic therapy approach to improve the treatment and or remission of T2D.

SP100 is an antiviral protein that restricts the productive stage of human papillomavirus(HPV)and multiple other viruses,and viruses in turn block sUMO-1-mediated stabilization of SP100 and promotes its degradation(Table S1).Interferon(IFN)signaling could still produce more SP100 through transcription to counteract viruses.1 Viruses also disable the transcriptional up-regulation of SP100 to achieve persistent infection in hosts.

Strokes are common around the world and especially in sub-Saharan Africa. They are responsible for severe sequelae and the majority of deaths. In Gabon, no study on stroke mortality has been conducted. Objective: To determine short, medium, long-term mortality and factors associated with long-term stroke mortality. Method: Our study took place in the Neurology Department of the University Hospital Center of Libreville (UHCL). It was a historical cohort study with descriptive and analytical purposes covering the period from June 1 to August 31, 2018 and taking into account hospitalized patients from January 1, 2013 to December 31, 2017. We conducted a comprehensive systematic recruitment of patients with stroke, 18 years old and more, and had been agreed to give information. We included all patients meeting the inclusion criteria. The data was gathered using Epi-Info 7 software. The CHI-2 test was used for the comparison of frequencies and the Student’s test, for comparison of means. Multivariate analysis with logistic regression allowed us to look for factors associated with long-term mortality. A result was statistically significant for a p 0.05 value. Results: At 3 months, 28 patients (18.1%) died, at 6 months thirty-one patients or 20.1% died. At 5 years old, fifty-three patients or 34.4% had died. The factors associated with long-term mortality, if the lost of sight were all alive were tobacco (p = 0.01) and stroke (p = 0.008). If all those who were lost to sight had died, no factor was associated with 5-year mortality. Conclusion: Stroke mortality must not be taken for granted, it can be underestimated because of the large number of lost sight. Measures must be put in place to strengthen post-stroke monitoring. .
