Biodegradable carrier are vital for the solid-phase denitrification (SPD) systems for treating nitrate-rich water. Two solid-phase denitrification reactors were developed with both 200 g L-1 of single (polycaprolactone, PCL) (R1) and hybrid solid carbon sources (PCL/polylactic acid (PLA) /polyhydroxyalkanoates (PHA)) (R2) to examine the denitrification performance, denitrifying community and functional genes to various oxytetracycline (OTC) exposure in this study, respectively. Complete denitrification performance was achieved in the both SPD systems at low stress of OTC (1 mg L-1), but then dramatically reduced to less than 20% of nitrate reduction efficiency after one-month high OTC stress (10 mg L-1), and rapidly recovered to stable nitrate removal rates of 76.77 ± 5.48% (R1) and 40.68 ± 4.40% (R2) after the next day of no OTC stress. However, the reactor R1 with single PCL carriers acquired more efficient nitrate removal rate than that of reactor R2 at the high OTC stress and recovery phase with OTC stress, mainly due to the more organics availability from the single PCL carriers. The richness and diversity of nirK and nirS deintrifiers significantly declined at high OTC stress, and much more of those occurred in biofilm R1 with more organics availability. Besides, biofilm R1 achieved much more abundant periplasmic nitrate reductase, nitrite reductase genes and tetracycline resistance genes after high OTC stress, which explained the potential resistance to OTC and rapid recovery efficiency after no stress of OTC. Thus, the organics availability played an important role in assuring SPD system to be efficient under high OTC stress.

Specific training in the management of trauma patients is beneficial for surgeons. Training through specific courses in this area has a direct impact on the care of these patients. The aim of this work is to understand the participation and specific training in the care of trauma patients by Spanish surgeons.

A national survey was conducted and administered to all members of the Spanish Association of Surgeons. The survey assessed their degree of participation in emergency surgery, and therefore the probability of attending trauma patients, their assessment of the initial care of trauma patients in their centre, and their specific training in this field.

UNC2250 was completed by 510 surgeons from 47 Spanish provinces, with Catalonia and Andalusia being the most represented regions. In total, 456 (89.41%) of those surveyed work in the emergency department on a routine basis. Only 171 (33.53%) refer to having a registry of trauma patients in their hospital. While 79.02% of surgeons reported that general surgeons are not involved in care of severe trauma from the outset, only 66.47% have completed the ATLS course, 40.78% the DSTC course and 18.82% the MUSEC course. Despite this, 85.69% believe that the ATLS course should be compulsory during residency and 43.33% believe that severe trauma care in their hospital is poor or very poor.

Only 40% have received specific training in definitive surgical management of severe trauma. Despite this, a large percentage of surgeons work in the emergency department on a routine basis and potentially face the challenge of managing these patients.

Individual contaminants are known to negatively affect microbial communities. However, the effect of multifaceted pollution on these communities is less well understood. #link# We investigated, using next-generation sequencing of the 16S rRNA genes, the effects of multisource (i.e., fertilizer industry and mining) chronic pollution on bacterial and archaeal communities in water and sediments from the Olifants River catchment, South Africa. Water samples showed less microbial species diversity than sediments and both habitats displayed different microbial communities. Within each of these habitats, pollution had no effect on alpha diversity but shaped the microbial composition and taxonomy-based predicted functions. Certain prokaryotic taxa and functional groups were indicative of different degrees of pollution. Heterotrophic taxa (e.g., Flavobacterium sp.) and sulphur-oxidizing bacteria (i.e., Thiobacillus sp.) were indicators of pollution in water and sediments, respectively. Ultimately, this information could be used to develop microbial indicators of water quality degradation.A Gram-stain-negative, aerobic, non-motile, non-spore-forming light-yellow-coloured rod-shaped bacterial strain, designated YJ15T, was isolated from soil at Bigeum island in Korea. Growth was observed at 10-37 °C (optimum, 28 °C), at pH 6.0-7.5 (optimum, pH 7.0) and in the absence of NaCl. Based on 16S rRNA gene sequence analysis, strain YJ15T was closely related to 'Lysobacter tongrenensis' YS037T (97.8%), Lysobacter pocheonensis Gsoil193T (96.5%) and Lysobacter daecheongensis Dae08T (95.8%) and phylogenetically grouped together with 'Lysobacter tongrenensis' YS037T, Lysobacter dokdonensis DS-58T and Lysobacter pocheonensis Gsoil 193T. The DNA-DNA relatedness between strain YJ15T and 'Lysobacter tongrenensis' KCTC 52206T was 12% and the phylogenomic analysis based on the whole genome sequence demonstrated that strain YJ20T formed a distinct phyletic line with Lysobacterlter dokdonensis DS-58T showing average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of 76.3 and 21.3%, respectively. The predominant ubiquinone was identified as Q-8, and polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two unidentified aminolipids. The major fatty acids were iso-C171 ω9c, iso-C150, iso-C160 and iso-C170. The genomic DNA G + C content was 68.2 mol %. On the basis of phenotypic, chemotaxonomic properties and phylogenetic analyses in this study, strain YJ15T is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter telluris sp. nov. is proposed. The type strain is YJ15T (= KACC 19552T = NBRC 113197T).Neurogenesis is a developmental process that involves fine-tuned coordination between self-renewal, proliferation, and differentiation of neural stem cells (NSCs) into neurons. However, early-life assault with environmental toxicants interferes with the regular function of genes, proteins, and other molecules that build brain architecture resulting in attenuated neurogenesis. Cypermethrin is a class II synthetic pyrethroid pesticide extensively used in agriculture, veterinary, and residential applications due to its low mammalian toxicity, high bio-efficacy, and enhanced stability. link2 Despite reports on cypermethrin-mediated behavioral and biochemical alterations, till now, no study implicates whether cypermethrin exposure has any effect on neurogenesis. Therefore, the present study was undertaken to comprehend the effects of cypermethrin treatment on embryonic and adult neurogenesis. We found that cypermethrin exposure led to a considerable decrease in the BrdU/Sox-2+, BrdU/Dcx+, and BrdU/NeuN+ co-labeled cells indicating that cypermethrin treatment decreases NSC proliferation and generation of mature and functional neurons. On the contrary, the generation of BrdU/S100β+ glial cells was increased resulting in neurogliogenesis imbalance in the hippocampus. Further, cypermethrin treatment also led to an increased number of BrdU/cleaved caspase-3+ and Fluoro-Jade B+ cells suggesting an induction of apoptosis in NSCs and increased degeneration of neurons in the hippocampus. Overall, these results explicate that cypermethrin exposure not only reduces the NSC pool but also disturbs the neuron-astrocyte ratio and potentiates neurodegeneration in the hippocampus, leading to cognitive dysfunctions in rats.In this review we summarize the cellular and molecular events of inflammation induced epithelial-to-mesenchymal (EMT) and mesothelial-to-macrophage transition (MET) during regeneration. Since the receptor transmits the environmental stimulus, downregulating or upregulating the process on an epigenetic level, the intracellular localization of receptors (signaling organelles early endosomes or lysosomal degradation late endosomes) plays a crucial role in the signaling events regulating inflammation and regeneration. Therefore, we focused on the internalization of the receptors as well as the intracellular compartmentalization of signaling molecules during EMT and MET. The review draws the reader's attention to the plasticity of mesothelial cells and supports the idea that during inflammation an ambient macrophage population might derive from mesothelial cells.Vasculogenic mimicry (VM) formed by aggressive tumor cells to mimic vasculogenic networks plays an important role in the tumor malignancy of HCC. However, the pathogenesis underlying VM is complex and has not been fully defined. m6A is a common mRNA modification and has many biological effects. However, the relationship between m6A and VM remains unclear. In this research, we found that m6A methyltransferase METTL3 in HCC tissues was positively correlated with VM. The m6A level of mRNA significantly increased in 3D cultured cells treated with VEGFa and was related to VM formation. Transcriptome sequencing analysis of 3D cultured cells with knockdown Mettl3 showed that the Hippo pathway was involved in m6A-mediated VM formation. Further mechanism research indicated that the m6A modification of YAP1 mRNA affected the translation of YAP1 mRNA. In conclusion, m6A methylation plays a key role in VM formation in HCC. METTL3 and YAP1 could be potential therapeutic targets via impairing VM formation in anti-metastatic strategies.The purpose of this study was to prospectively evaluate the distribution of PSMA-targeted, PET-avid lesions in prostate cancer (PCa) patients with biochemical recurrence in a Chinese cohort. The relationships between PSA levels, disease-free time after prostatectomy, and 68Ga-PSMA-11 PET/computed tomography (CT) findings were investigated. Inclusion criteria included histopathologically proven prostate adenocarcinoma, two consecutive PSA levels > 0.20 ng/mL, and negative CT of the abdomen and pelvis or magnetic resonance imaging of the pelvis and whole-body bone scan. Exclusion criteria were non-prostate malignancy within 3 years and persistent PSA after radical prostatectomy. Patients with findings of recurrent disease on re-staging conventional imaging were excluded, as were patients previously treated with systemic therapy and/or salvage therapy. 51 patients were enrolled in this study. 34/51 (66.7%) patients had at least one site of 68Ga-PSMA-11 uptake consistent with PCa. link3 23.5% of patients had recurrence in the prostate bed, 27.4% had pelvic lymph nodes, 15.7% had extrapelvic lymph node metastases, and 17.6% had bone metastases. For patients with lymph node involvement/metastasis, bone metastasis, and patients with both, their median serum PSA levels were 1.83 ng/mL, 2.54 ng/mL, and 4.03 ng/mL, respectively. They were diagnosed with recurrence with a median of 2.06 years, 2.54 years, and 1.15 years after radical prostatectomy, respectively. In this study of Chinese men with biochemical recurrence, added value for the detection of lesions compatible with sites of PCa was found with 68Ga-PSMA-11 PET/CT over conventional imaging. The observed patterns of disease spread may have implications for understanding the biology of early prostate cancer metastasis.
