[Potassium channels and autophagy].

Potassium channels have multitudinous subtypes, which are widely distributed on cell membranes. They affect various cellular physiological functions through participating in processes such as resting potential formation, substance transportation, enzyme activity and cellular communication. Autophagy is a significant mechanism to maintain intracellular metabolic homeostasis. The abnormity of autophagy may lead to the occurrence and development of multiple diseases. Recently, it has been reported that K+ channels and cell autophagy are closely related. Here, we reviewed the recent research progresses on regulation of autophagy signaling, autophagy flux or autophagolysosome formation by K+ channel, and discussed the physiological significance of autophagy regulation by K+ channel.

Morphology and Phylogeny Reveal Three Montagnula Species from China and Thailand.

Four stains were isolated from two fresh twigs of Helwingia himalaica and two dead woods during investigations of micro-fungi in China and Thailand. Phylogenetic analyses of four gene regions LSU, ITS, SSU and tef1-α revealed the placement of these species in Montagnula. Based on the morphological examination and molecular data, two new species, M. aquatica and M. guiyangensis, and a known species M. donacina are described. Descriptions and illustrations of the new collections and a key to the Montagnula species are provided. Montagnula chromolaenicola, M. puerensis, M. saikhuensis, and M. thailandica are discussed and synonymized under M. donacina.

Pleocatenatachiangraiensis gen. et. sp. nov. (Pleosporales, Dothideomycetes) from medicinal plants in northern Thailand.

Pleocatenata, a new genus, is introduced with its type species, Pleocatenatachiangraiensis, which was isolated from withered twigs of two medicinal plants, Clerodendrumquadriloculare (Blanco) Merr (Verbenaceae) and Tarennastellulata (Hook.f.) Ridl (Rubiaceae) in northern Thailand. The genus is characterized by mononematous, septate, brown or dark brown conidiophores, monotretic conidiogenous cells and catenate, obclavate, olivaceous to blackish brown conidia. Phylogenetic analysis of combined LSU, SSU, tef1-α, rpb2 and ITS sequence data showed Pleocatenata forms a distinct phylogenetic lineage in Pleosporales, Dothideomycetes. Therefore, we treat Pleocatenata as Pleosporales genera incertae sedis based on morphology and phylogenetic analyses. Descriptions and illustrations of the new taxa are provided, and it is compared with morphologically similar genera.

Modification of m6A mediates tissue immune microenvironment in calcific aortic valve disease.

Background: Several human diseases are associated with aberrant expression of regulators involved in N6-methyladenosine (m6A) RNA modification. However, their role in aortic valve calcification (AVC) is largely unknown. The aim of this study was to determine the general expression pattern and potential function of m6A regulators in AVC by bioinformatics methods. Methods: We obtained AVC datasets from the Gene Expression Omnibus (GEO). The identification of m6A-related differentially expressed genes (DEGs) and the Consensus Clustering method was performed to type AVC individuals based DEGs. Then, we quantified the effect of typing by principal component analysis (PCA). Next, we performed the weighted gene co-expression network analysis (WGCNA) and identified the main modules as well as functional analysis. Additionally, the key genes were screened by protein-protein interaction network (PPIN) analysis and identifying important genes of important modules. We again typed AVC individuals by the same method using key genes. Finally, we evaluated the link between key genes and immune infiltration. Results: We discovered that METTL14, ZC3H13, FTO, FMR1, HNRNPA2B1, HNRNPC, LRPPRC, YTHDC1, YTHDC2, and YTHDF1 expression levels decreased considerably in AVC tissues. Based on 10 genes, we typed 240 AVC samples as clusters A and B. We assessed the immune cell content in 240 samples using Cell-type Identification by Estimating Relative Subsets of RNA Transcripts (CIBERSORT) and found that B cell memory, CD8 T cells, T follicular helper cells, monocytes, M0 macrophages, resting dendritic cells (DCs), and interleukin-10 (IL-10) were concentrated in the cluster A group. Additionally, based on the important WGCNA modules, we identified 7 key genes. Next, 240 samples were retyped based on 7 key genes; we found that T cells CD8, T cells CD4 memory activated, T cells follicular helper, and macrophages M1 were significantly increased in gene cluster-1. Finally, we performed functional enrichment of gene cluster-typed samples, showing potential functional differences between different types. Conclusions: Our study provides a review of the m6A regulators' expression pattern and functional importance in human AVC. The data from this study might serve as a significant resource for future mechanistic and therapeutic investigations into the role of critical m6A regulators in AVC.

Additions to Neopestalotiopsis (Amphisphaeriales, Sporocadaceae) fungi: two new species and one new host record from China.

Background: In this study, three Neopestalotiopsis taxa were identified, associated with leaves of Zingiberofficinale, Elaeagnuspungens and Salaccazalacca. New information: Based on morphology and multi-gene analyses of the internal transcribed spacer (ITS), beta-tubulin (TUB2) and translation elongation factor 1-alpha (TEF1), the five strains of Neopestalotiopsis represent two novel and one known species. They are introduced with descriptions, illustrations and notes herein.

Assessment of the effectiveness of parent-targeted interventions for the use of child restraint systems: a systematic review and meta-analysis.

Background: It is essential to implement parent-targeted interventions to increase the use of child restraint systems (CRS) and thus reduce the injuries and deaths of children due to motor vehicle collisions. To optimize future intervention designs, this meta-analysis sought to quantify the effects of parent-targeted interventions and explore potential intervention moderators. Methods: Studies met inclusion criteria if they included a parents-targeted intervention that focused on increasing CRS use for children, published from the inception of the databases to January 2022, were systematically retrieved from the PubMed, Embase, Cochrane library, Web of Science, Sinomed, Wanfang, and CNKI databases. Next, 2 researchers independently screened the retrieved articles, evaluated their quality according to the Cochrane Tool, and extracted the data. Finally, Stata12.0 was used for the meta-analysis. Heterogeneity was examined with I2, stratified analyses, and meta-regression. Results: Of the 1,690 articles retrieved, 9 studies, comprising 22,329 parents of children aged 0-12 years, were ultimately included in the analysis. The results of the meta-analysis showed that the CRS use rate of the intervention group was 1.62 times higher than that of the control group [95% confidence interval (CI): 1.25-2.11, Z=3.616, P<0.001], indicating the positive effect of parent-targeted interventions on promoting the use of CRS. The subgroup analysis found that interventions guided by behavioral theories increased the use of CRS (odds ratio: 1.44, 95% CI: 1.27-1.63, n=5). The difference in the use of CRS between the groups in the studies that were not guided by theories was not statistically significant, indicating that interventions guided by behavioral theories may be the source of the heterogeneity. Risk of bias was low in most studies. Conclusions: It is necessary to conduct interventions with parents to increase the use of CRS. The effects on CRS use appear to differ depending on whether the interventions are guided by behavioral theories. In-depth research needs to be conducted to explore the characteristics of the interventions, especially those guided by different behavioral theories, to reduce child vehicle injuries.

Morphology and Phylogeny Reveal Vamsapriyaceae fam. nov. (Xylariales, Sordariomycetes) with Two Novel Vamsapriya Species.

Phylogenetic analyses of combined LSU, rpb2, tub2 and ITS sequence data of representative Xylariales taxa indicated that Diabolocovidia, Didymobotryum and Vamsapriya cluster together and form a distinct clade in Xylariales. Morphological comparison also shows their distinctiveness from other families of Xylariales. Therefore, we introduce it as a novel family, Vamsapriyaceae. Based on morphological characteristics, Podosporium and Tretophragmia, which were previously classified in Ascomycota genera incertae sedis, are now included in the Vamsapriyaceae. In addition, three Vamsapriya species, V. chiangmaiensis sp. nov, V. uniseptata sp. nov, and V. indica are described and illustrated in this paper.

Different Expression of MicroRNA-146a in Peripheral Blood CD4(+) T Cells and Lesions of Oral Lichen Planus.

Oral lichen planus (OLP) is a common T cell-mediated chronic inflammatory disease of unknown etiology. Recent increasing evidence indicates that microRNA-146a (miR-146a) plays a vital role in inflammatory diseases and T cell regulation. This study aimed to investigate the expression of miRNA-146a in peripheral blood CD4(+) T cells and local OLP lesions and to evaluate its relationship with clinical forms of OLP. Sixteen patients with OLP were divided into two groups: erosive OLP and nonerosive OLP. The expression of miR-146a was examined by quantitative real-time polymerase chain reaction. The expression of miR-146a in peripheral blood CD4(+) T cells showed no significant difference between OLP group and control group (P > 0.05), and among erosive OLP, nonerosive OLP, and control groups (P > 0.05 for all). The expression in local lesions of the OLP group was significantly higher than that of the control group (P = 0.003), and it was significantly higher in the erosive OLP group than in the non-erosive OLP (P = 0.010) and control groups (P = 0.007). However, miR-146a expression in the nonerosive OLP group did not significantly differ from that in the control group (P > 0.05). These data indicate that miR-146a might be more involved in the local immune disorder of OLP. MiR-146a might be utilized as a candidate biomarker to estimate the severity of OLP.

Radon concentrations in drinking water in Beijing City, China and contribution to radiation dose.

(222)Rn concentrations in drinking water samples from Beijing City, China, were determined based on a simple method for the continuous monitoring of radon using a radon-in-air monitor coupled to an air-water exchanger. A total of 89 water samples were sampled and analyzed for their (222)Rn content. The observed radon levels ranged from detection limit up to 49 Bq/L. The calculated arithmetic and geometric means of radon concentrations in all measured samples were equal to 5.87 and 4.63 Bq/L, respectively. The average annual effective dose from ingestion of radon in drinking water was 2.78 µSv, and that of inhalation of water-borne radon was 28.5 µSv. It is concluded that it is not the ingestion of waterborne radon, but inhalation of the radon escaping from water that is a substantial part of the radiological hazard. Radon in water is a big concern for public health, especially for consumers who directly use well water with very high radon concentration.
