Interactions between riverine sediment organic matter molecular structure and microbial community as regulated by heavy metals.

Heavy metals (HMs) exert a profound influence on soil carbon storage potential. The microbially-mediated association between HM content and carbon structure in riverine sediments remains unclear in lotic ecosystems. We investigated the spatiotemporal variations of HMs content, carbon content and microbial communities in riverine surface sediments, and further explored the chemical structure of sediment organic carbon (OC), the molecular composition of dissolved organic matter (DOM), and their interactions with microorganisms.

Cellulose separation from ramie bone by one step process with green hydrogen peroxide-citric acid.

Ramie bone (RB), an agricultural waste generated in the textile industry, is a vastly productive renewable natural resource with the potential to be used as a source of cellulose. In this study, ramie bone cellulose (RB-CE) was obtained in one step using a simple and ecologically friendly hydrogen peroxide-citric acid (HPCA) treatment procedure that avoided the use of halogenated reagents and strong acids while also streamlining the treatment processes. Various analytical methods were used to investigate the chemical composition and structure, crystallinity, morphology, thermal properties, surface area and hydration properties of cellulose separated at different treatment temperatures.

Relating bacterial dynamics and functions to greenhouse gas and odor emissions during facultative heap composting of four kinds of livestock manure.

Although facultative heap composting is widely used in small and medium-sized livestock farms in China, there are few studies on greenhouse gas (GHG) and odor emissions from this composting system. This study focused on GHG and odor emissions from facultative heap composting of four types of livestock manure and revealed the relationship between the gaseous emissions and microbial communities. Results showed that pig, sheep, and cow manure reached high compost maturity (germination index (GI) > 70%), whereas chicken manure had higher phytotoxicity (GI = 0.

Structured postoperative handover protocol improves efficiency and quality of interdisciplinary communication and nursing care in surgical intensive care unit: a randomized controlled trial.

This study aimed to evaluate the effectiveness of a structured postoperative handover protocol for postoperative transfer to the SICU. This study was a randomized controlled trial conducted in a comprehensive teaching hospital in China. Patients who were transferred to the SICU after surgery were randomly divided into two groups.

A global meta-analysis of greenhouse gas emissions and carbon and nitrogen losses during livestock manure composting: Influencing factors and mitigation strategies.

The management of manure composting contributes to alleviate the global greenhouse effect. To improve our understanding of this process, we conducted a meta-analysis of 371 observations from 87 published studies in 11 countries. The results showed that the difference in nitrogen content in feces significantly affected the greenhouse gas (GHG) emissions and nutrient losses of subsequent composting, with NH-N, CO-C, and CH-C losses all increasing with its rise.

Overcoming the Trade-Off between C H Sorption and Separation Performance by Regulating Metal-Alkyne Chemical Interaction in Metal-Organic Frameworks.

Designing porous materials for C H purification and safe storage is essential research for industrial utilization. We emphatically regulate the metal-alkyne interaction of Pd and Pt on C H sorption and C H /CO separation in two isostructural NbO metal-organic frameworks (MOFs), Pd/Cu-PDA and Pt/Cu-PDA. The experimental investigations and systematic theoretical calculations reveal that Pd in Pd/Cu-PDA undergoes spontaneous chemical reaction with C H , leading to irreversible structural collapse and loss of C H /CO sorption and separation.

Effects of dicyandiamide, phosphogypsum and superphosphate on greenhouse gas emissions during pig manure composting.

This study investigated the effects of dicyandiamide, phosphogypsum and superphosphate on greenhouse gas emissions and compost maturity during pig manure composting. The results indicated that the addition of dicyandiamide and phosphorus additives had no negative effect on organic matter degradation, and could improve the compost maturity. Adding dicyandiamide alone reduced the emissions of ammonia (NH), methane (CH) and nitrous oxide (NO) by 9.

NR4A3 fluorescence in situ hybridization analysis in cytologic and surgical specimens of acinic cell carcinoma.

Acinic cell carcinoma (AciCC) may pose a diagnostic challenge, particularly on small biopsies and fine needle aspiration (FNA) because of its variable histology including potential high-grade transformation and its mimickers. Immunoreactivity with circumferential membranous staining for DOG1 can support the diagnosis of AciCC but is not entirely specific. A novel rearrangement t(4;9)(q13;q31) leading to up-regulation of nuclear receptor subfamily 4 group A member 3 (NR4A3) has been described in AciCC, is potentially detectable by fluorescence in situ hybridization (FISH) and may be useful in the evaluation for AciCC.

Composting temperature directly affects the removal of antibiotic resistance genes and mobile genetic elements in livestock manure.

The high antibiotic resistance gene (ARGs) contents in livestock manure pose a potential risk to environment and human health. The heap composting with an ambient temperature and thermophilic composting are two methods for converting livestock manure into fertilizer. This study investigated the variations in ARGs and mobile genetic elements (MGEs) and revealed potential mechanisms for ARGs removal using the two composting methods.

ASF1B: A Possible Prognostic Marker, Therapeutic Target, and Predictor of Immunotherapy in Male Thyroid Carcinoma.

Background: Thyroid carcinoma (TC) is the most common malignant endocrine tumor worldwide. Several studies have documented that male patients with TC have a higher rate of metastasis and disease recurrence than female patients. However, the mechanism underlying this observation is not completely clear.

A two-microRNA signature predicts the progression of male thyroid cancer.

In various cancers, microRNAs (miRNAs) are abnormally expressed, including thyroid cancer (TC). In recent years, the incidence of TC has increased annually around the world. Compared with female patients, male TC patients are more likely to have a postoperative recurrence and lymph node metastasis, and hence need second treatments.

The Cytochrome Complex Is Essential for Chromate and Sulfide Resistance and Is Regulated by a GbsR-Type Regulator, CydE, in Sp. WH16-1.

Sulfate-reducing bacteria are a group of microorganisms that use sulfate as an electron acceptor. These bacteria are useful in the bioremediation of heavy metal pollution since they can reduce/precipitate metals. Previously, we identified the strain WH16-1 from soil of a copper and iron mine and determined that it can reduce sulfate and chromate and that it was tolerant to many heavy metals.

Chorionic Histiocytic Hyperplasia is Associated With Chronic Inflammatory Lesions in the Placenta.

Background Chorionic histiocytic hyperplasia (CHH) is a cellular proliferation at the base of the chorion that was identified by the authors in examining placentas for chronic chorioamnionitis (CC). This study is a retrospective review of cases diagnosed with CHH, describing its incidence alone and with associated lesions, and the immunophenotype of lesional cells. Design In this retrospective study, a laboratory information system search over a 34-month period using the key phrase "chorionic stromal" was performed.

Draft genomic sequence of a chromate- and sulfate-reducing Alishewanella strain with the ability to bioremediate Cr and Cd contamination.

Alishewanella sp. WH16-1 (= CCTCC M201507) is a facultative anaerobic, motile, Gram-negative, rod-shaped bacterium isolated from soil of a copper and iron mine. This strain efficiently reduces chromate (Cr(6+)) to the much less toxic Cr(3+).

Description of two marine amphisiellid ciliates, Amphisiella milnei (Kahl, 1932) Horváth, 1950 and A. sinica sp. nov. (Ciliophora: Hypotrichia), with notes on their ontogenesis and SSU rDNA-based phylogeny.

The morphology and taxonomy of two marine Amphisiella species, isolated from mariculture waters in northern China, were investigated using standard techniques. One species corresponds well with the original description of the poorly known Amphisiella milnei (Kahl, 1932) Horváth, 1950 by remarkable characteristics, inter alia, (i) the additional cirri between the left frontal cirrus and the buccal cirrus, and (ii) ring-shaped structure in the anterior and posterior body portion (posterior one sometimes lacking). The detailed description of the cirral pattern and an informative ontogenetic stage first reveal that the additional cirri, which are uniformly absent in all congeners, originate from the frontal-ventral transverse cirral anlage I.

A sarcoidosis-like granuloma reaction in the lymph nodes of a patient with lung squamous cancer: from stasis to the invasive phase with FGFR1 gene amplification.

Background: Granulomatous inflammation is considered an immune mechanism against infection or certain non-neoplastic conditions. Sarcoidosis-like granuloma reactions (SGRs) in primary tumors or in regional lymph nodes are occasionally observed; however, they are rare in lung cancer.

Case Review: In this study, we reported on a case of squamous lung cancer with swollen mediastinal lymph nodes, similar to sarcoidosis.
