A 12-week feeding trial was conducted to investigate the effects of dietary arginine (Arg), glutamine (Gln), and their interactions on growth performance, nonspecific immunity, disease resistance, and Arg catabolism in juvenile turbot (Scophthalmus maximus L.). The basal diet was formulated with white fish meal, soybean meal, and corn gluten meal to contain 50% crude protein and 12% crude lipid. Nine isoproteic and isolipidic experimental diets were formulated by supplementing the basal ...

This experiment investigated the effects of dissolved oxygen (DO) on the survival and immune responses of scallop Chlamys farreri. The scallops (initial mean dry weight of soft tissue 1.52+/-0.10 g) were cultivated in the seawater with different DO levels (8.5, 6.5, 4.5, and 2.5mg l(-1), respectively) for 21 d. Each treatment had triplicate groups of 35 animals. During the experimental period, the scallops were fed with Spirulina maxima, and water temperature ranged from 15.2 degrees C ...

A water-soluble glucan, namely, PD3, was isolated from the fruiting body of Dictyophora indusiata as the method reported previously. Its chemical structure was characterized by GC, FTIR, and (13)C NMR. The results indicated that PD3 is a (1-->3)-beta-D-glucan, with (1-->6)-beta-glucopyranoside side branches. The chain conformation and morphology of PD3 in aqueous solution were investigated by viscometry, rheometer, and laser light scattering (LLS) measurements, atomic force microscopy ...

INTRODUCTION: The extent of optimal gastric resection for proximal gastric cancer (PGC) continues to remain controversial, and a final consensus is yet to be met. The current study aimed to compare the perioperative outcomes, postoperative complications, and overall survival (OS) of proximal gastrectomy (PG) versus total gastrectomy (TG) in the treatment of PGC through a meta-analysis.

METHODS: We systematically searched PubMed, Embase, The Cochrane Library, and Web of Science for ...

Metablastin (also called p19, stathmin, prosolin, p18, Lap18, and oncoprotein 18) is a highly conserved, cytosolic 149-amino acid polypeptide that is expressed in immature vertebrate cells and undergoes extracellular factor- and cell cycle-regulated serine phosphorylation. The protein was shown recently to destabilize microtubules in vitro (Belmont, L., and Mitchison, T. J. (1996) Cell 84, 623-631). Here we demonstrate that microinjection of recombinant metablastin induces a loss of ...

Our previous study has demonstrated that luteinized granulosa cells (GCs) have the potential to proliferate and that the telomerase activity (TA) of luteinized GCs may predict the clinical outcomes of IVF treatment. However, in the field of telomere research, there have always been different opinions regarding the significance of TA and telomere length (TL). Thus, in the present study, we compared the effects of these two parameters on IVF treatment outcomes in the same individuals. TL ...

BACKGROUND: To build a new and appropriate model of secondary intra-abdominal hypertension (IAH) in rats.

METHODS: A total of 32 female Sprague-Dawley rats were randomized into four groups. Group I: the rats were hemorrhaged to a mean arterial pressure (MAP) of 40 mm Hg for 1 h and portal hypertension was induced by partial ligation of the portal vein 1 h later; Group II: after inducing portal hypertension, hemorrhagic shock of MAP of 40 mm Hg was induced and maintained for 1 h; Group ...

The coronavirus disease 2019 (COVID-19) pandemic has led to worldwide efforts to understand the biological traits of the newly identified human coronavirus (HCoV-19) virus. In this mass spectrometry (MS)-based study, we reveal that out of 21 possible glycosites in the HCoV-19 spike protein (S protein), 20 are completely occupied by N-glycans, predominantly of the oligomannose type. All seven glycosylation sites in human angiotensin I converting enzyme 2 (hACE2) were found to be ...

Water-soluble and water-insoluble polysaccharide fractions were isolated from fruiting bodies of Ganoderma lucidum (rheishi) by extraction with phosphate buffer and 1 N sodium hydroxide solutions at different temperatures and investigated by high-performance liquid chromatography (HPLC), one- and two-dimensional 1H and 13C NMR, infrared (IR) spectroscopy, and other techniques. This work was prompted by Sone et al.’s earlier conclusion that similarly extracted, water-insoluble ...

The treatment of triple-negative breast cancer (TNBC) relies largely on chemotherapies. However, it is frequent that TNBC patients develop resistance to the chemotherapy drugs. Generation of drug-resistant cell lines facilitates the identification of drug resistance. Here, we established two paclitaxel (PTX)-resistant TNBC cancer cell lines using an intermittent and stepwise method and found that long non-coding RNA long intergenic non-protein-coding RNA p53-induced transcript ...

BackgroundAlzheimer’s disease has become a public health crisis globally due to its increasing incidence. The purpose of this study was to establish an early warning model using artificial neural network (ANN) for early diagnosis of AD and to explore early sensitive markers for AD.MethodsA population based nested case-control study design was used. 89 new AD cases with good compliance who were willing to provide urine and blood specimen were selected from the cohort of 2482 ...

A label-free electrochemical biosensor based on the triplex DNA-templated Ag/Pt bimetallic nanoclusters (triplex-Ag/PtNCs) and locked nucleic acid (LNA) modified X-shaped DNA probe was developed for the detection of single-nucleotide variant (SNV) related to β-thalassemia. Firstly, using triplex DNA as template, a site-specific and homogeneous Ag/PtNCs was prepared, which can effectively catalyze the 3,3,5,5-tetramethylbenzidine-H2O2 system and thus be employed as a signal reporter in ...

RATIONALE AND OBJECTIVES: To investigate whether iodine quantification extracted from enhanced dual energy-computed tomography (DE-CT) is useful for distinguishing lung squamous cell carcinoma from adenocarcinoma and to evaluate whether a single scan evaluated during the venous phase (VP) can be substituted for scans evaluated during other phases.

MATERIALS AND METHODS: Sixty-two patients with lung cancer (32 squamous cell carcinomas; 30 adenocarcinomas) underwent enhanced dual-phase ...

PurposeTo compare the neonatal birthweight of singletons derived from ICSI cycles with fresh or frozen–thawed epididymal sperm in patients with obstructive azoospermia.MethodsA total of 436 singletons derived from ICSI cycles with fresh (n = 220) or frozen–thawed (n = 216) epididymal sperm in obstructive azoospermia evaluated from 2012 to 2018 in the retrospective study. Multivariate generalized linear model was used to analyze the association between epididymal sperm cryopreservation ...

The corrosion inhibition behavior of mercaptobenzothiazole (MBT) on copper in 0.1 M H2SO4 solutions was investigated by bulk acoustic wave (BAW) sensor under open-circuit condition in this paper. The growth process of Cu-MBT complex film was monitored by the BAW sensor and the frequency shift curves were acquired. The frequency shift curves were fitted with a proposed model and the maximum frequency shift and the apparent rate constant of film formation were obtained. The relations ...
