Lin Wang, Yuting Qian, Yun Cao, Ying Huang, Zhizhou Chang, Hongying Huang
Thermoactinomyces sp. strain YT06 was isolated from poultry compost and observed to degrade integral chicken feathers at 60°C completely, resulting in the formation of 3.24 mg/mL of free amino acid from 50 mL of culture containing 10 g/L chicken feathers. Strain YT06 could grow and secret keratinase using feather as the only carbon and nitrogen sources without other supplement, but complementation of 10 g/L sucrose and 4 g/L NaNO₃ increased the production of the keratinolytic enzyme. The maximum protease activities obtained were 110 U/mL and keratinase were 42 U/mL...

The present study evaluated the potential modulatory effect(s) of dietary supplementation with Spirulina platensis (SP) on Atrazine (ATZ)-induced oxidative stress and inflammation in common carp (Cyprinus carpio L.). Common carp was exposed to ATZ (428μg/L) and SP (1%), either alone or in combination, for 40 days. Subsequently, the treatment groups were evaluated for ATZ-induced oxidative stress-mediated hepatic damage and the potential antioxidant effect(s) of SP supplementation. The results indicated that ATZ exposure led to a significant increase in the oxidative stress as suggested by the increased levels of lipid and DNA oxidative damage markers and the significant decline of antioxidant status biomarkers...

Spiroplasma spp., tiny filterable wall-less bacteria, are consistently associated with the transmissible spongiform encephalopathies (TSE). Spiral forms have been transiently isolated from TSE-affected brain tissues in SP4 growth media designed for isolation of Spiroplasma spp., but the isolate could not be propagated in SP4 media. A bacterium must grow in vitro in cell-free cultures to allow full characterization of a suspect pathogen. Here, a novel Spiroplasma sp. was isolated from scrapie- and chronic wasting disease (CWD)-affected brains and lymph nodes...

Rickettsiae are associated with a diverse range of invertebrate hosts. Of these, mosquitoes could emerge as one of the most important vectors because of their ability to transmit significant numbers of pathogens and parasites throughout the world. Recent studies have implicated Anopheles gambiae as a potential vector of Rickettsia felis. Herein we report that a metagenome sequencing study identified rickettsial sequence reads in culicine mosquitoes from the Republic of Korea. The detected rickettsiae were characterized by a genus-specific quantitative real-time PCR assay and sequencing of rrs, gltA, 17kDa, ompB, and sca4 genes...

Although Memorial Delirium Assessment Scale (MDAS) is a successful tool for delirium evaluation and monitoring, it is nevertheless important to determine whether cut-off scores vary according to the studied population. The main objective of this study is to evaluate the diagnostic sensitivity of the recently validated Spanish version of the MDAS. The secondary objective is to analyze possible diagnostic differences when used in a hospice or general hospital setting. METHODOLOGY: A prospective study was conducted with advanced cancer patients in two settings (hospice & general hospital)...

Yujuan Han, Rilei Yu, Peixin Gao, Xinzhi Lu, Wengong Yu
CsnA, a chitosanase from Renibacterium sp. QD1, has great potential for industrial applications due to its high yield and broad pH stability. In this study, a specific Glu160 in CsnA was identified by sequence alignment, and structural analysis and MD simulation predicted that Glu160 formed a hydrogen-bond network with Lys163 and Thr114. To evaluate the effect of the network, we constructed four mutants, including E160A, E160Q, K163A, and T114A, which partially or completely destroy this network. Characterization of these mutants demonstrated that the disruption of the network significantly decreased the enzyme thermostability...

Seminal plasma (SP) is considered as a vehicle to carry sperm into female reproductive tract, of which functions have not been completely understood. This study aimed to identify the function of seminal exosomes on porcine endometrium. Exosomes were isolated from the sperm-rich fraction of boar semen and were confirmed by the expression of exosome marker HSP70 and size distribution using nano-sight tracking analysis. Porcine endometrial epithelial cells (EECs) were then treated with seminal exosomes, and RNA extracted were subjected to global expression analysis...

As an abundant and renewable polysaccharide, chitosan has been drawing broad attention due to its natural properties. For the further utilization of chitosan, chemical modification can be applied in improving its water solubility and the bioactivities. In this study, four chitosan derivatives were synthesized by the reaction of chloracetyl chitosan derivative with quaternary ammonium salt (CTCS) and urea groups bearing 4-amino-pyridine, including BCTCS, 2CBCTCS, 3CBCTCS, and 4CBCTCS. The structure characteristics of synthesized products were established based on FT-IR spectroscopy, (1)H NMR, and elemental analysis...

AIMS: Although the epidermal growth factor receptor (EGFR) and Wnt/β-catenin signaling systems synergistically regulate many essential developmental and regenerative processes in lung cancer, the mechanisms of their crosstalk remain poorly defined. Our study aimed to investigate an interaction between EGFR and the β-catenin signal. RESULTS: In this study, we described a potent activation of β-catenin by EGFR, which is dependent of the PtdIns3K/AKT pathway. We found EGF activated β-catenin signaling via phosphorylation of EGFR and AKT in EGFR-mutated PC-9 lung cancer cells...

Microcystins (MCs) are serine/threonine phosphatase inhibitors synthesized by several members of the phylum Cyanobacteria. Mining the draft genome sequence of the nostocalean MC-producing Fischerella sp. strain CENA161 led to the identification of three contigs containing mcy genes. Subsequent PCR and Sanger sequencing allowed the assembling of its complete biosynthetic mcy gene cluster with 55,016 bases in length. The cluster encoding ten genes (mcyA-J) with a central bidirectional promoter was organized in a similar manner as found in other genera of nostocalean cyanobacteria...

Self-efficacy beliefs are strong predictors of academic pursuits, performance, and persistence, and in theory are developed and maintained by 4 classes of experiences Bandura (1986) referred to as sources: performance accomplishments (PA), vicarious learning (VL), social persuasion (SP), and affective arousal (AA). The effects of sources on self-efficacy vary by performance domain and individual difference factors. In this meta-analysis (k = 61 studies of academic self-efficacy; N = 8,965), we employed B. J...

Tetrabutylammonium decatungstate (TBADT)-photocatalyzed C-H functionalization of alkylpyridines was investigated. Unlike alkylbenzene counterparts, alkylation of α-C-H bonds did not proceed for the reaction of 2- and 4-alkylpyridines and reluctantly proceeded for 3-alkylpyridines, which allow site-selective C(sp(3))-H functionalization at nonbenzylic positions. The observed nonbenzylic site selectivities are rationalized by the polar inductive effects of pyridyl groups in the SH2 transition states. Consecutive γ-functionalization and α-bromofunctionalization were successfully carried out in selected cases...

The discovery of mammalian target of rapamycin (mTOR) kinase inhibitors has always been a research hotspot of antitumor drugs. Consensus scoring used in the docking study of mTOR kinase inhibitors usually improves hit rate of virtual screening. Herein, we attempt to build a series of consensus scoring models based on a set of the common scoring functions. In this paper, twenty-five kinds of mTOR inhibitors (16 clinical candidate compounds and 9 promising preclinical compounds) are carefully collected, and selected for the molecular docking study used by the Glide docking programs within the standard precise (SP) mode...
