Nitrogen-Rich Triazine-Based Covalent Organic Frameworks as Efficient Visible Light Photocatalysts for Hydrogen Peroxide Production.

Covalent organic frameworks (COFs) have been widely used in photocatalytic hydrogen peroxide (HO) production due to their favorable band structure and excellent light absorption. Due to the rapid recombination rate of charge carriers, however, their applications are mainly restricted. This study presents the design and development of two highly conjugated triazine-based COFs (TBP-COF and TTP-COF) and evaluates their photocatalytic HO production performance.

This study provides a way of thinking about the evaluation of the green innovation level of the logistics industry.

Relationship between ABO blood group and gestational diabetes mellitus: A protocol for systematic review and meta-analysis.

Background: Gestational diabetes mellitus (GDM) is a common metabolic disorder syndrome in women during pregnancy. If effective measures are not taken to intervene in the early stage of GDM, severe effects will damage maternal and infant health. ABO is the most important human blood group system.

Effect of Knockout Serum Replacement During Postwarming Recovery Culture on the Development and Quality of Vitrified Parthenogenetic Porcine Blastocysts.

The postwarming recovery culture, as one of the steps in cryopreservation process, is directly correlated with the survival and quality of embryos. Generally, recovery medium includes undefined serum or serum components that may cause the instability of results and other problems. The objective of this study was to evaluate the effect of knockout serum replacement (KSR) as a substitute for serum during recovery culture on the development and quality of vitrified parthenogenetic porcine blastocysts.

The Replacement of Monosaccharide by Mannitol or Sorbitol in the Freezing Extender Enhances Cryosurvival of Ram Spermatozoa.

In this study, the protective effects of monosaccharides (glucose and fructose) and sugar alcohols (mannitol, sorbitol, and xylitol) on frozen ram spermatozoa were evaluated and compared. The motility, moving velocity, and hypoosmotic swelling capability of spermatozoa frozen with monosaccharide or sugar alcohol were measured using a computer-assisted spermatozoa analyzer system. The acrosome status, membrane integrity, distribution of phosphatidylserine (PS), and mitochondrial membrane potential (MMP) were analyzed using fluorescence staining and flow cytometry.

Meiotic maturation and developmental capability of ovine oocytes at germinal vesicle stage following vitrification using different cryodevices.

In order to assess effects of vitrification on ovine oocytes at the germinal vesicle (GV) stage, the conventional plastic straw (CS), the open-pulled straw (OPS), and Cryoloop were used to vitrify ovine oocytes. Oocytes were randomly divided into five groups: (1) Control; (2) Oocytes exposed to vitrification and dilution solutions without any cryopreservation (toxicity); (3) Oocytes vitrified using CS (CS); (4) Oocytes vitrified using OPS (OPS), and (5) Oocytes vitrified using Cryoloop (Cryoloop). The viability, cumulus cell expansion, nuclear maturation after in vitro maturation (IVM), and developmental capability of vitrified oocytes following parthenogenetic activation (PA) or in vitro fertilization (IVF) were assessed.

Effects of Hoechst33342 staining on the viability and flow cytometric sex-sorting of frozen-thawed ram sperm.

Cytometric sorting of frozen-thawed sperm can overcome difficulties caused by the unavailability of sorting facilities on farms where semen is collected from male livestock. In order to optimize the cytometric sex-sorting procedure, effects of Hoechst33342 staining on the viability and cytometric sorting efficiency of frozen-thawed ram sperm were evaluated. The frozen-thawed sperm were stained with Hoechst33342 at various dye concentrations (80 μM, 120 μM, 160 μM, 200 μM, 240 μM, or 320 μM) for 45 min to evaluate effects of dye dose.

Associations between serum 25-hydroxyvitamin D and disease activity, inflammatory cytokines and bone loss in patients with rheumatoid arthritis.

Objective: The aim of this study was to describe the associations between serum levels of 25-hydroxyvitamin D [25(OH)D] and disease activity, inflammatory cytokines and bone loss/erosions in patients with RA.

Methods: The study included 130 patients with RA and 80 healthy controls. Serum 25(OH)D, IL-17 and IL-23 levels were detected by ELISA.

Establishment and cryopreservation of a skin fibroblast cell line derived from Yunnan semi-fine wool sheep in the presence of synthetic ice blocker.

In this study, the fibroblasts cell line derived from ear marginal tissue of Yunnan semi-fine wool sheep was successfully established using the primary explants technique and cryopreservation technology. Additionally, the protective effect of synthetic ice blocker (SIB) including 1, 3-cyclohexanediol (1, 3-CHD) and 1, 4-cyclohexanediol (1, 4-CHD) on frozen fibroblast cells was also assessed and compared. Propidium iodide (PI) was used to stain the dead cells following cryopreservation and thawing.

Comparison of the effect of various disaccharides on frozen goat spermatozoa.

In order to create a bank of goat spermatozoa, it was important to evaluate the protective effect of five different cryoprotectant extenders. Additionally, this study determined whether the cryoprotective effect of trehalose is superior to that of other disaccharides. The data indicate that the motility (~20%) and path velocity (~15 μm/s) of spermatozoa frozen with extenders containing disaccharide were significantly less than that of spermatozoa frozen with extender containing no disaccharide (45.

The effects of trehalose and sucrose on frozen spermatozoa of Yunnan semi-fine wool sheep during a non-mating season.

To improve the quality of frozen spermatozoa of Yunnan semi-fine wool sheep, the protective effect of trehalose and sucrose on frozen ram spermatozoa during a non-mating season was evaluated and compared in this study. Briefly, following collection by electric stimulation, equilibration at degree C following dilution with the freezing extender, and pre-freezing in liquid nitrogen vapor, the ram spermatozoa were frozen in liquid nitrogen. After thawing, viability, motility, acrosome status, membrane integrity, and phosphatidylserine (PS) distribution was determined using a computer-assisted spermatozoa analysis system and flow cytometry.
