vity against skin pathogens. Conclusions The results obtained in the present study support that the infusions from common bistort influence key biological processes are crucial for skin conditions with the inflammatory background. The study justifies the traditional topical application of common bistort.Ethnopharmacological relevance Chronic obstructive pulmonary disease (COPD) is a respiratory inflammatory disease. Unlike asthma, COPD is insensitive to glucocorticoid treatment; thus, it is of great importance to find alternative medications, including Chinese medicine, to suppress inflammation. Bu-Shen-Fang-Chuan formula (BSFCF) is commonly used for the treatment of COPD in China. However, the mechanisms of BSFCF in COPD treatment are still unclear. Aim of the study To verify the anti-inflammatory efficacy of BSFCF in COPD and to explore the possible mechanisms underlying its anti-inflammatory efficacy based on the phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt)-Nuclear factor erythroid 2-related factor 2 (Nrf2) and Nuclear factor (NF)-κB signalling pathways. Materials and methods A rat model of COPD was established by chronic exposure to cigarette smoke (CS) for 6 months. Bronchoalveolar lavage fluid (BALF) and blood were obtained to detect inflammatory cytokines. Lung samples were harvested, and part of each sample was fixed for subsequent H&E staining and immunohistochemical (IHC) analysis. The remaining lung tissues were used for RNA sequencing analysis and western blotting. Results BSFCF significantly reduced inflammatory infiltration in the lungs of CS-exposed rats and decreased the concentrations of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in both the BALF and serum. Additionally, BSFCF evidently attenuated NF-κB activation and downregulation of glucocorticoid receptor (GR) caused by CS. Furthermore, BSFCF increased the activation of PI3K/Akt-Nrf2 signalling in response to CS. Conclusions BSFCF attenuated CS-induced inflammation in COPD, which was partially achieved through the PI3K/Akt-Nrf2 and NF-κB signalling pathways.Cotton (Gossypium hirsutum L.) is an important economic crop. Cytoplasm male sterility (CMS) has been used to develop hybrid system and to produce hybrid seeds in cotton, but the molecular mechanism of CMS remains unclear. Mitochondria are semi-autonomous organelles, which play an important role in the reproduction of flowering plants. Male sterility has been proved associated with mitochondrial dysfunction in plants. In present study, a new strategy of proteomic sequencing data-independent acquisition (DIA) was used to analysis protein abundance across CMS lines 2074A (cytoplasm of Gossypium harknessii, D2-2) and 2074S (cytoplasm of G. hirsutum, AD1), and their maintainer 2074B. Comparing with transcriptome results showed that there is little consistence between proteome and transcriptome. A total of 2095 protein species were identified in three materials, and 186 and 161 differentially proteins were detected in the comparisons of 2074A vs 2074B, and 2074S vs 2074B, respectively. Among them, 49 and 50 proteiwering, which showed different expression pattern between the male sterile line 2074A and maintainer 2074B. This novel research based on mitochondrial proteomics comparison confirmed that DAPs related to oxidative stress are critical to pollen abortion. BIOLOGICAL SIGNIFICANCE Cytoplasm male sterility (CMS) system is utilized widely for hybrid production in cotton. However, the genetic and molecular mechanisms of CMS still need to be further elucidated. Up till now, fewer comprehensive comparisons of the mitochondrial proteomes from cotton CMS line and maintainer line have been reported. In this study, we performed a novel comparison of mitochondrial protein profiles in two CMS lines and their common maintainer line. Based on our results, we found a potential protein related to oxidative stress led to the anthers abortion. These results accumulate data to interpret the molecular mechanisms of CMS in cotton.MALDI mass spectrometry imaging (MALDI MSI) is a spatially resolved analytical tool for biological tissue analysis by measuring mass-to-charge ratios of ionized molecules. With increasing spatial and mass resolution of MALDI MSI data, appropriate data analysis and interpretation is getting more and more challenging. A reliable separation of important peaks from noise (aka peak detection) is a prerequisite for many subsequent processing steps and should be as accurate as possible. We propose a novel peak detection algorithm based on sparse frame multipliers, which can be applied to raw MALDI MSI data without prior preprocessing. The accuracy is evaluated on a simulated data set in comparison with state-of-the-art algorithms. These results also show the proposed method's robustness to baseline and noise effects. In addition, the method is evaluated on real MALDI-TOF data sets, whereby spatial information can be included in the peak picking process. SIGNIFICANCE The field of proteomics, in particular MALDI Imaging, encompasses huge amounts of data. The processing and preprocessing of this data in order to segment or classify spatial structures of certain peptides or isotope patterns can hence be cumbersome and includes several independent processing steps. In this work, we propose a simple peak-picking algorithm to quickly analyze large raw MALDI Imaging data sets, which has a better sensitivity than current state-of-the-art algorithms. Further, it is possible to get an overall overview of the entire data set showing the most significant and spatially localized peptide structures and, hence, contributes all data driven evaluation of MALDI Imaging data.Aim In a previous study, low and high-normal arterial carbon dioxide tension (PaCO2) were not associated with serum neuron-specific enolase (NSE) in cardiac arrest survivors. We assessed the effect of PaCO2 on NSE in cerebrospinal fluid (CSF) and serum. PD-1 inhibitor Methods This was a retrospective study. PaCO2 for the first 24 h was analysed in four means, qualitative exposure state (qES), time-weighted average (TWA), median, and minimum-maximum (Min-Max). These subgroups were divided into low (LCO2) and high PaCO2 (HCO2) groups defined as PaCO2 ≤ 35.3 and PaCO2 > 43.5 mmHg, respectively. NSE was measured at 24, 48, and 72 h (sNSE24,48,72 and cNSE24,48,72) from return of spontaneous circulation (ROSC). The primary outcome was the association between PaCO2 and the NSE measured at 24 h after ROSC. Results Forty-two subjects (male, 33; 78.6%) were included in total cohort. PaCO2 in TWA subgroup was associated with cNSE24,48,72, while PaCO2 in the other subgroup were only associated with cNSE24. PaCO2 and cNSE in qES subgroup showed good correlation (r = -0.
