Etomidate protects retinal ganglion cells from hydrogen peroxide-induced injury Nrf2/HO-1 pathway.

Aim: To determine whether etomidate (ET) has a protective effect on retinal ganglion cells (RGCs) injured with hydrogen peroxide (HO) and to explore the potential mechanism underlying the antioxidative stress effect of ET.

Methods: Cultured RGCs were identified by double immunofluorescent labeling of microtubule-associated protein 2 and Thy1.1.

miR-460b-5p promotes proliferation and differentiation of chicken myoblasts and targets RBM19 gene.

The meat production of broilers is crucial to economic benefits of broiler industries, while the slaughter performance of broilers is directly determined by skeletal muscle development. Hence, the broiler breeding for growth traits shows a great importance. As a kind of small noncoding RNA, microRNA (miRNA) can regulate the expression of multiple genes and perform a wide range of regulation in organisms.

Comparative Analysis of miRNA Expression Profiles in Skeletal Muscle of Bian Chickens at Different Embryonic Ages.

MicroRNAs (miRNAs) are widely involved in the growth and development of skeletal muscle through the negative regulation of target genes. In order to screen out the differentially expressed miRNAs (DEMs) associated with skeletal muscle development of Bian chickens at different embryonic ages, we used the leg muscles of fast-growing and slow-growing Bian chickens at the 14th and 20th embryonic ages (F14, F20, S14 and S20) for RNA-seq. A total of 836 known miRNAs were identified, and 121 novel miRNAs were predicted.

Optimization of Cultivation Conditions of Lingzhi or Reishi Medicinal Mushroom, Ganoderma lucidum (Agaricomycetes) for the Highest Antioxidant Activity and Antioxidant Content.

Ganoderma lucidum is a famous medicinal mushroom that is rich in antioxidants. The content of antioxidant components of grains can be effectively improved by G. lucidum as the fermenting strain.

Clinical anatomy and mechanical tensile properties of the rectus femoris tendon.

Purpose: We aimed to provide anatomical data and mechanical tensile properties for the rectus femoris tendon to determine if it is a feasible substitute for the anterior cruciate ligament during knee joint reconstruction.

Methods: The length and width of the quadriceps femoris tendon were measured from ten adult cadavers (20 knees; age =48±2 years). The anatomic features of the patellar insertion on the quadriceps femoris tendon were also documented.

Construction of Radial Defect Models in Rabbits to Determine the Critical Size Defects.

Many studies aimed at investigating bone repair have been conducted through animal models in recent years. However, limitations do exist in these models due to varying regeneration potential among different animal species. Even using the same animal, big differences exist in the size of critical size defects (CSD) involving the same region.

Presepsin as a novel sepsis biomarker.

Background: In 2004, a new biomarker sCD14-subtypes (presepsin) was found and its value was shown in the diagnosis and evaluation of sepsis. This article is a brief overview of the new biomarker.

Data Sources: A literature search using multiple databases was performed for articles, especially meta-analyses, systematic reviews, and randomized controlled trials.

Inhibition of SENP5 suppresses cell growth and promotes apoptosis in osteosarcoma cells.

SUMOylation is a dynamic and reversible process. Several SUMO-specific proteases (SENPs) that remove SUMO from substrates have been shown to be amplified in a subset of cancers. SENP5 is required for cell division, as well as maintaining mitochondrial morphology and function.

Predicting value of serum soluble ST2 and interleukin-33 for risk stratification and prognosis in patients with acute myocardial infarction.

Background: Acute myocardial infarction (AMI) is a common cardiac emergency with high mortality. Serum soluble ST2 (sST2) is a new emerging biomarker of cardiac diseases. The present study is to investigate the predictive value of sST2 and interleukin-33 (IL-33) for risk stratification and prognosis in patients with AMI.

PPIase independent chaperone-like function of recombinant human Cyclophilin A during arginine kinase refolding.

Whether Cyclophilin A (CyPA) functions as a foldase or a chaperone when assisting protein folding has long been argued. In this study, we engineered four variants of recombinant human Cyclophilin A (rhCyPA), all of which were inactive to tetrapeptide substrate Suc-AAPF-pNA. However, these variants were able to suppress aggregation during arginine kinase (AK) refolding as efficient as wild-type rhCyPA, especially, variant Q63A had even more efficiency to suppress aggregation and improve reactivation yields of AK.

Mutation of residue arginine 330 of arginine kinase results in the generation of the oxidized form more susceptible.

Arginine kinase (AK), a crucial enzyme for the energy metabolism of invertebrates, catalyzes the reversible phosphorylation of arginine by Mg(2+)ATP to form phosphoarginine and Mg(2+)ADP. Arginine 330 (R330), not involved in the catalysis of phosphoryl transfer, is a residue highly conserved in the phosphagen kinase family. In order to investigate the role of R330 in AK, it was replaced by lysine (R330K).

Clinical characteristics and prognosis of heart failure with normal left ventricular ejection fraction in elderly patients.

Background: The term heart failure with normal ejection fraction (HFNEF) is often used to describe the syndrome of heart failure with normal ejection fraction. Based on the previous studies, HFNEF has a significant morbidity and mortality and is associated with a similar prognosis to heart failure with reduced ejection fraction (HFREF). The present study aimed to investigate the clinical characteristics and prognosis of HFNEF in elderly patients.

Evidences of monomer, dimer and trimer of recombinant human cyclophilin A.

Cyclophilin A (CyPA) is a cytosolic receptor of immunosuppressive drug cyclosporin A (CsA) which possesses peptidyl-prodyl cis/trans isomerase (PPIase) activity. The recombinant human CyPA (rhCyPA) gene has been expressed in E. coli M15.

[Risk factors and warning signs of sudden cardiac death].

Sudden cardiac death (SCD) is the most common death mode. No test has been able to accurately predict SCD. This article reviews the risk factors and warning signs of SCD with an attempt to effectively prevent SCD events.
