Thus, we could directly probe the effect of the backbone knot and the decrease in conformational entropy on protein folding. The backbone cyclization did not perturb the native structure and its cofactor binding affinity, but it substantially increased the thermal stability and reduced the aggregation propensity. The enhanced stability of a backbone knotted YibK could be mainly originated from an increased ruggedness of its free energy landscape and the destabilization of the denatured state by backbone cyclization with little contribution from a knot structure. Despite the heterogeneity in the side-chain compositions, the chemically unfolded cyclized YibK exhibited several macroscopic physico-chemical attributes that agree with theoretical predictions derived from polymer physics.The serious shuttle effect, low conductivity, and large volume expansion have been regarded as persistent obstacles for lithium sulfur (Li-S) batteries in its practical application. Carbon materials, such as graphene, are considered as promising cathode hosts to alleviate those critical defects and be possibly coupled with other reinforcement methods to further improve the battery performance. However, the open structure of graphene and the weak interaction with sulfur species restrict its further development for hosting sulfur. MK-8776 Herein, a rational geometrical design of hierarchical porous graphene-like bubbles (PGBs) as a cathode host of the Li-S system was prepared by employing magnesium oxide (MgO) nanoparticles as templates for carbonization, potassium hydroxide (KOH) as activation agent, and car tal pitch as a carbon source. The synthesized PGBs owns a very thin carbon layer around 5 nm that can be comparable to graphite nanosheets. Its high content of mesoporous and interconnected curved structure can effectively entrap sulfur species and impose restrictions on their diffusion and shuttle effect, leading to a much stable electrochemical performance. The reversible capacity of PGBs@S 0.3 C still can be maintained at 831 mAh g-1 after 100 cycles and 512 mAh g-1 after 500 cycles.[This corrects the article DOI 10.3389/fpubh.2020.589359.].It took a white police officer's knee on George Floyd's neck before white people began to reckon with 400 years of slavery and its aftermath, the effects of which Black people have endured for generations. Monuments are being taken down, flags are being redesigned, and institutions that honored those who denied the humanity of Black people are being renamed. Unfortunately for Sandra Bland, Breonna Taylor, Sha-Asia Washington and countless other Black transgender people including those with capacity for pregnancy, there was no justice even prior to the global pandemic of SARS-Cov-2 or coronavirus; namely racism, violence, and the Black Maternal Health crisis that makes it less likely that Black women will survive pregnancy and childbirth. The purpose of this article is to situate the state of Black people with the capacity for pregnancy in the context of these existing crises to illuminate the myths that racism has perpetuated through science, health services provision and policy. The greatest of these is the an actionable roadmap to specifically disrupt the myth of the default human and dismantle racism in education, provision of care, research, policies, and public health praxis.Background There is increased interest in early intervention and prevention of mental health difficulties during adolescence; thus, we are seeing increased efforts to optimize well-being during this epoch. Positive emotional experiences are a central component of overall well-being. However, research exploring what adolescents perceive to be the cause(s) of their emotional difficulties is lacking. Improving understanding of this issue within non-clinical adolescent groups may provide useful insight into how to develop strategies to support young people as they navigate emotional difficulties. Objectives The aim of this research was to explore if meaningful categories of perceived cause(s) for emotional distress exist for non-clinical adolescent groups. Methods The data for this study were drawn from interviews across 6 sites in England conducted as part of the 5-year national evaluation of the HeadStart Learning Programme. The sample comprised of 32 young people aged 11-12 years from the first annual wave of qualitative data collection in 2017. Ideal type analysis-a qualitative form of person-centered analysis-was used to construct a typology of adolescents perceived cause(s) for emotional distress. Findings We identified five distinct categories of perceived cause (1) perceived lack of control; (2) unfair treatment; (3) others, their actions and judgements as the catalyst; (4) concerns for self and others; and, (5) self as cause. Conclusions Our findings illustrate that distinct categories for perceived cause of emotional distress exist among adolescents considered to be "at risk" of developing mental health difficulties, which provides a foundation for future necessary work seeking to investigate the possible link between perceived cause for emotional distress and help-seeking behavior among sub-clinical groups.Coronavirus disease 2019 (COVID-19) is caused by a new coronavirus, namely severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is currently spreading all over the world. In this paper, we developed a practical model for identifying the features of cytokine storm, which is common in acute infectious diseases and harmful manifestation of COVID-19, by distinguishing major and minor clinical events. This model is particularly suitable for identifying febrile and infectious diseases like COVID-19. Based on this model, features of cytokine storm and pathogenesis of COVID-19 have been proposed to be a consequence of the disequilibrated cytokine network resulting from increased biological activity of transforming growth factor-β (TGF-β), which induces certain clinical manifestations such as fatigue, fever, dry cough, pneumonia, abatement and losing of olfactory, and taste senses in some patients. Research and clarification of the pathogenesis of COVID-19 will contribute to precision treatment. Various anti-TGF-β therapies may be explored as potential COVID-19 treatment.
