IL-6 is a cytokine that plays an important role in response to injury or infection and is a promising biomarker for predicting poor prognosis and therapeutic targets in non-small cell lung cancer (NSCLC). This article reviews the biochemical mechanism, function and genotype of IL-6, and summarizes the diagnostic and prognostic value of IL-6 level. Anti-IL-6 therapy does not affect the effect of immunocheckpoint inhibitors (ICIs), but enhances its anticancer function, which may be the treatment option for immune-related adverse events (irAEs) in the future. Therefore, IL-6 may be a therapeutic target for the treatment of NSCLC. © 2020 The Authors.

Many field studies find that distributions of LRS among individuals are non-normal, zero-inflated and highly skewed. These results beg the question, what is the distribution of LRS predicted by demographic models when the only source of randomness is demographic stochasticity? Here we present the first exact analysis of the probability distribution of LRS for species described by age + stage models; our analysis starts with estimated vital rates. We illustrate with three examples the Hadza, human hunter-foragers (age-only), the evergreen tree Tsuga canadensis (stage-only) and Roe deer, Capreolus capreolus (age + stage). For each we obtain the exact distribution of LRS, but also calculate and discuss the first three moments. Our results point to important questions about how such LRS distributions affect natural selection, and life history evolution. © 2020 John Wiley & Sons Ltd/CNRS.BACKGROUND Beck Depression Inventory (BDI-II) is a widely used valid instrument to assess the severity of depression in clinical and normal settings. To meet the necessity of a standard scale for measuring depression among above 265 million Bangla speaking population around the world, this scale was translated and validated. METHODS Two translations of BDI-II into Bangla were prepared, and then, two back translations were done by medical and language experts in parallel. Thereafter, sentence revision followed by pretest on 20 respondents was done to finalize the Bangla version of BDI-II (BDI-II BV). Afterward, a cross-sectional, comparative, and descriptive study was conducted to validate the scale by purposive sampling technique consisting of 111 persons (both clinical and normal) in three tertiary-level hospitals in Bangladesh. Everyone was given to fill up BDI-II BV at first. Then, they were given to fill up BDI-II BV (n = 49), Bangla version of Depression Anxiety Stress Scales 21-item (DASS21-BV, n = 47) y among the Bengali population. © 2020 The Authors. Brain and Behavior published by Wiley Periodicals, Inc.Energy and environmental issues have given rise to the development of advanced energy storage devices worldwide. Electrochemical energy technologies, such as rechargeable batteries, have been considered to be the most reliable and efficient candidates. Compared with other batteries, zinc-based batteries seem promising due to their advantages including inherent safety, cost-effectiveness and environmental-friendliness. As potential alternatives to conventional inorganic cathodes, organic cathodes for zinc-organic batteries have become the research hotspot owing to their favorable characteristics, such as easy structure design, controllable synthesis and environmental benignancy. In this paper, we provide a systematical overview on the fundamentals of organic cathode materials for zinc batteries including material design, electrochemical mechanisms, technical advances and challenge analysis. Furthermore, the perspectives and corresponding research directions are offered in order to facilitate the future development of organic cathode materials for zinc batteries toward practical applications. © 2020 WILEY-VCH Verlag GmbH & Co.

In this study, spherical Nannochloropsis sp. and ellipsoidal Monoraphidium sp. suspensions were dewatered in the presence of different amounts of 350-nm magnetite particles using a microfiltration membrane with 360-nm pores in cross-flow mode. Magnetite functions as a filter aid by reducing the deformation of the cake of filtered algae on the membrane and providing paths for water to flow through the filtration cake of algae. In the case of Nannochloropsis sp., the highest dewatering rate was obtained when the number ratio, defined based on the size and ideal density, between Nannochloropsis sp. and magnetite was 112.5, but the addition of magnetite had no observable effect on the filtration of ellipsoidal Monoraphidium sp. suspensions through the membrane. After dewatering, magnetite was effectively separated from the concentrated algal suspension by the application of a magnetic field in an open flow system. Magnetite has the potential to enhance dewatering performance using a cross-flow membrane system. © 2020 American Institute of Chemical Engineers.AIMS To investigate the natural history and genotype-phenotype correlation of pantothenate kinase-associated neurodegeneration. METHODS We collected data of patients with PKAN by searching from available publications in English and Chinese. Patients diagnosed in our center (Peking University First Hospital) were also included. The difference in natural history and genotype between early-onset ( less then 10 year of age at onset) and late-onset patients (≥10 year of age at onset) with PKAN was compared. RESULTS A total of 248 patients were included. The median age at onset was 3.0 years in the early-onset group and 18.0 years in the late-onset group. Dystonia in lower limbs was the most common initial symptom in both groups. In the early-onset group, the median interval between the disease onset and occurrence of oromandibular dystonia, generalized dystonia, loss of independent ambulance was 6.0 years, 5.0 years, and 5.0 years. BKM120 cell line The corresponding values in late-onset group were 1.0 year, 4.0 years, and 6.0 years.
