The purpose of this study was to investigate the role of urea-N recycling, rumen bacterial community, and rumen epithelial gene expression in nitrogen utilization of calves. Here, 12 Holstein calves were divided into two dietary treatments: a high-protein diet (HP, 173 g/kg), and a low-protein diet (LP, 125 g/kg). Urea-N kinetics was evaluated using urea-15N15N isotope labeling method. Gene expression in rumen epithelium and liver, bacterial diversity, and metabolites in rumen were characterized using transcriptomic,...

COVID-19 is caused by SARS-CoV-2 infection and was initially discovered in Wuhan. This outbreak quickly spread all over China and then to more than 20 other countries. SARS-CoV-2 fluorescent microsphere immunochromatographic test strips were prepared by the combination of time-resolved fluorescence immunoassay with a lateral flow assay. The analytical performance and clinical evaluation of this testing method was done and the clinical significance of the testing method was verified. The LLOD of SARS-CoV-2 antibody IgG...

Quantile treatment effects can be important causal estimands in the evaluation of biomedical treatments or interventions for health outcomes such as birthweight and medical cost. However, the existing estimators require either a propensity score model or a conditional density vector model is correctly specified, which is difficult to verify in practice. In this paper, we allow multiple models for propensity score and conditional density vector, then construct a class of calibration estimators based on multiple...

A new ingol diterpenoid, namely 3-de-O-acetyleuphornan R (1), along with two known analogues, euphornans E (2) and N (3) were isolated from the seeds of Euphorbia marginata Pursh. The structure of 1 was elucidated by extensive 1H NMR, 13C NMR, HSQC, HMBC, and 1H-1H COSY, and HR-MS spectroscopic analyses.

To evaluate the psychometric properties of the Chinese Fear of Cancer Recurrence Inventory (FCRI-C) in follicular lymphoma (FL) survivors. A nationwide cross-sectional study was conducted online between July and September 2020. The following psychometric properties of the FCRI-C were evaluated: construct, convergent, and discriminant validity, and reliability. Item variance was assessed using differential item functioning (DIF). A short version of the FCRI-C was developed using a two-parameter item response theory (IRT) model. The patterns of...

Surra, one of the most important animal diseases with economic consequences in Asia and South America, is caused by Trypanosoma evansi. However, the mechanism of immune evasion by T. evansi has not been extensively studied. In the present study, T. evansi extracellular vesicles (TeEVs) were characterized and the role of TeEVs in T. evansi infection were examined. The results showed that T. evansi and TeEVs could activate TLR2-AKT pathway to inhibit the secretions of IL-12p40,...

Few mental health assessment tools are available for people with hearing loss (HL) in China. The Acceptance and Action Questionnaire-Adult Hearing Loss (AAQ-AHL) has been specifically designed to assess psychological inflexibility in adults with HL and may help assess mental health status promptly for targeted psychological interventions. The study aimed to investigate the cross-cultural validity and reliability of the Chinese version of the AAQ-AHL to assess its applicability to teenagers and adults with HL in...

A new aromatic glycoside (1) and twelve (2–13) known aromatic glycosides were isolated from the n-butyl alcohol of the 70% EtOH extract of the aerial part of Bupleurum chinense. Among them, compounds 4–7, 9, 11–13 were isolated from Umbelliferae plants for the first time. Their structures were elucidated by NMR and MS spectroscopy, and the absolute configuration of compound 1 was elucidated by single-crystal X-ray diffraction. Compounds 6 and 10 showed moderate cytotoxic activities on...

To get additional insight into the genetic factors of attention deficit hyperactivity disorder (ADHD). First, we performed a transcriptome-wide association study (TWAS) integrating human cerebellum-specific variant-expression/splicing correlations to identify ADHD susceptibility genes. Then, the associations between expression/splicing quantitative trait loci (eQTLs/sQTLs) of the transcriptome-wide significant genes and ADHD were observed in a case-control study of Han Chinese children. Furthermore, dual luciferase reporter gene assays were performed to validate the regulatory function of ADHD risk variants....

Targeting the immunological checkpoint PD-1/PD-L1 with antibodies has shown opportunities to improve cancer treatment in recent years. However, antibody therapy is a double-edged sword with high cost, low patient tolerance, lack of oral bioavailability, and a reaction to most solid tumors that prevents the adoption of antibodies. Advancement of small-molecule PD-1/PD-L1 inhibitors that could overwhelm these drawbacks is sluggish because of the poor pharmacodynamic properties and shallow pocket of the PD-1/PD-L1 binding interface. Recently, a...

This work studied the physical properties of three deep eutectic solvents (DESs) and their catalytic activity in the esterification of palmitic acid and ethanol. Three types of deep eutectic solvents (DESs) were successfully prepared using p-toluene sulfonic acid monohydrate (PTSA) as hydrogen bond donor (HBD) with dodecyl trimethyl ammonium chloride (DTAC), tetradecyl trimethyl ammonium chloride (TTAC) and octadecyl trimethyl ammonium chloride (OTAC) as hydrogen bond acceptor (HBA). The freezing points of DESs were measured in...

This paper considers a single-machine scheduling problem with sequence-dependent setup times and energy-generation and storage systems. Each job requires a sequence-dependent setup to be processed on the machine, and both setup and processing of the job require job-dependent amounts of energy. The energy consumed by the machine can be bought from an Electric Power Company (EPC) or generated by own Distributed Energy Resource (DER), such as solar photovoltaic or wind, and the energy can be...

Tumor-derived exosomes (exo) could modulate the biological behaviors of human umbilical vein endothelial cells (HUVECs). Here, the role of microRNA (miR)-10a-5p-modified gastric cancer (GC) cells-derived exo for HUVECs was studied. GC tissue specimens were collected, and miR-10a-5p and zinc finger MYND-type containing 11 (ZMYND11) levels were determined. HUVECs interfered with ZMYND11 or miR-10a-5p-related oligonucleotides. Exo was extracted from GC cells (HGC-27 exo), and miR-10a-5p mimic-modified HGC-27 exo were co-cultured with HUVECs. HUVECs viability, migration and...

The kth (1<k≤ 2) power expectile regression (ER) can balance robustness and effectiveness between the ordinary quantile regression and ER simultaneously. Motivated by a longitudinal ACTG 193A data with nonignorable dropouts, we propose a two-stage estimation procedure and statistical inference methods based on the kth power ER and empirical likelihood to accommodate both the within-subject correlations and nonignorable dropouts. Firstly, we construct the bias-corrected generalized estimating equations by combining the kth power ER and inverse...

A new cyclo-pentazolate anion-based energetic cocrystal NH4N5 · 1/6NH4Cl was synthesized. The structure, thermal behavior, sensitivity, and detonation properties of NH4N5 · 1/6NH4Cl were studied. Cube-shaped NH4N5 · 1/6NH4Cl crystallizes in the Fd-3 m space group, and is formed by hydrogen bonding interactions. DSC-TG-MS combined techniques show that NH4N5 · 1/6NH4Cl has better thermal stability than NH4N5. The cocrystal exhibits low impact and friction sensitivity, and largely reduces the mechanical sensitivity of NH4N5. Furthermore, the...

It was found that bisphenol F (BPF) could be anaerobically transformed to 4,4-dihydroxybenzophenone using nitrate as an electron acceptor by Pseudomonas sp. LS. However, BPF removal was a slow process under anaerobic conditions. In the present study, effects of graphene oxide (GO) and graphene on the anaerobic transformation of BPF were studied in detail. Results showed that GO (2–10 mg/L) and graphene (2–20 mg/L) could increase the anaerobic biotransformation rate of BPF. For GO-mediated system,...

Immune checkpoint inhibitors (ICIs) -induced adverse events (AEs) have been reported affecting almost all human organs. However, studies about ocular AEs are few. A meta-analysis was performed to evaluate the risks of ICI-related ophthalmic AEs compare to chemotherapy. Methods: Eligible studies were selected from phase II/III randomized controlled trials investigating ICIs. The data were analyzed by R software and Stata. Odds ratio of treatment-related AE (trAEs) and nonspecific ophthalmic trAEs (NS-trAEs) were lower for PD-1/PD-L1...
