Denosumab biosimilar (LY06006) in Chinese postmenopausal osteoporotic women: A randomized, double-blind, placebo-controlled, multicenter phase III study.

Objectives: This study assessed the efficacy, safety, pharmacokinetics (PK), and immunogenicity profiles of a denosumab biosimilar (LY06006) in Chinese postmenopausal osteoporotic women with a high risk of fracture.

Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase 3 trial, 448 postmenopausal women aged 50-85 years with osteoporosis were enrolled at 49 centers in China and were randomly assigned (3:1) to receive 60 ​mg of the denosumab biosimilar (LY06006) or placebo subcutaneously every 6 months for 1 year. Lumbar spine bone mineral density (BMD) change was the primary endpoint.

Identification and functional characterization of bactericidal permeability/increasing protein (BPI) from frog Nanorana yunnanensis (Paa yunnanensis).

Bactericidal permeability/increasing protein (BPI) and lipopolysaccharide-binding protein (LBP) have been most extensively studied in mammals, but little information is available regarding BPI and LBP in Amphibia. In this study we showed that the cDNA of BPI in the frog N. yunnanensis (P.

CHANGES IN MYOPIC MACULOPATHY BASED ON ATN CLASSIFICATION SYSTEM: An Optical Coherence Tomography Angiography Study.

Purpose: To assess changes in myopic maculopathy based on the ATN classification system with optical coherence tomography angiography.

Methods: This was a cross-sectional study. The macular choroidal thickness (MCT) and the choriocapillaris flow (CC) were measured with optical coherence tomography angiography.

A Review of the Associations Between Obstructive Sleep Apnea and Gestational Diabetes Mellitus and Possible Mechanisms of Disease.

Obstructive sleep apnea (OSA) usually leads to the occurrence of diabetes. Gestational diabetes mellitus (GDM) is a common gestational complication associated with adverse maternal and fetal outcomes. Increasing studies suggest that women with OSA during pregnancy may be at a significantly greater risk of developing GDM.

14,15-EET involved in the development of diabetic cardiac hypertrophy mediated by PPARs.

Cardiac hypertrophy is a key structural change in diabetic cardiomyopathy, which mechanism is unknown. 14,15-Epoxyeicosatrienoic acid (14,15-EET) generated from arachidonic acid by CYP2J2 has beneficial effects in metabolic syndrome, which also plays vital roles in inflammatory response. Peroxisome proliferator activated receptors (PPARs) are members of the nuclear receptor superfamily and have three subtypes of α, β (or δ) and γ.

Development of a nomogram for predicting the risk of left ventricular diastolic function in subjects with type-2 diabetes mellitus.

Left ventricular diastolic dysfunction (LVDD) can be affected by many factors, including epicardial adipose tissue (EAT), obesity and type-2 diabetes mellitus (T2DM). The aim of this study was to establish and validate an easy-to-use nomogram that predicts the severity of LVDD in patients with T2DM. This is a retrospective study of 84 consecutive subjects with T2DM admitted to the Endocrinology Department, the First People's Hospital of Zunyi City between January 2015 and October 2020.

PPARβ down-regulation is involved in high glucose-induced endothelial injury via acceleration of nitrative stress.

Endothelial injury plays a vital role in vascular lesions from diabetes mellitus (DM). Therapeutic targets against endothelial damage may provide critical venues for the treatment of diabetic vascular diseases. Peroxisome proliferator-activated receptor β (PPARβ) is a crucial regulator in DM and its complications.

Pueribacillus theae gen. nov., sp. nov., isolated from Pu'er tea.

A novel bacterial strain, designated T8, isolated from ripened Pu'er tea, was investigated by using a polyphasic taxonomic approach. Cells stained Gram-positive and were aerobic, sporogenous and rod-shaped with flagella. Phylogenetic analysis of 16S rRNA gene sequences revealed the strain belonged to the family Bacillaceae in the class Bacilli and represented an independent taxon separated from other genera.

Activities of Amphioxus GH-Like Protein in Osmoregulation: Insight into Origin of Vertebrate GH Family.

GH is known to play an important role in both growth promotion and osmoregulation in vertebrates. We have shown that amphioxus possesses a single GH-like hormone (GHl) gene encoding a functional protein capable of promoting growth. However, if GHl can mediate osmoregulation remains open.

Trans-generational enhancement of C-type lysozyme level in eggs of zebrafish by dietary β-glucan.

β-glucan has been shown to increase non-specific immunity and resistance against infections or pathogenic bacteria in several fish species, but information regarding its trans-generational immune-enhancing effects is still rather limited. Lysozyme is a maternal immune factor playing an important role in the developing embryos of zebrafish. Here we clearly showe that β-glucan enhanced the level of C-type lysozyme in eggs of zebrafish, and the embryos derived from β-glucan-treated zebrafish were more resistant to bacterial challenge than control embryos.

Zebrafish phosvitin-derived peptide Pt5 inhibits melanogenesis via cAMP pathway.

Zebrafish phosvitin-derived peptide Pt5, consisting of the C-terminal 55 residues of phosvitin, has been shown to have an antimicrobial-immunomodulatory activity comparable to phosvitin. Here, we showed clearly that Pt5 had the capacity to inhibit tyrosinase (TYR) activity and melanin biosynthesis, and this inhibition was independent of cell proliferation and cytotoxic effects. Incubation of fluorescein isothiocyanate (FITC)-labeled Pt5 with B16F10 melanoma cells revealed that Pt5 was localized in the cytoplasm of the cells.

Antibacterial activity and modes of action of phosvitin-derived peptide Pt5e against clinical multi-drug resistance bacteria.

Pt5e, a mutant peptide derived from the C-terminal 55 residues of zebrafish phosvitin, has been suggested to be a novel antibacterial peptide. However, if it is applicable to clinical MDR bacteria remains to be tested. In this study, high-purity Pt5e was first expressed and purified by fusion with cationic elastin-like polypeptide.

Dietary β-glucan enhances the contents of complement component 3 and factor B in eggs of zebrafish.

β-glucan has been shown to increase non-specific immunity and resistance against infections or pathogenic bacteria in several fish species, but no information is available regarding its trans-generational effects to date. Here we clearly demonstrated that β-glucan enhanced the contents of immune-relevant molecules C3 and Bf in eggs of zebrafish, and the embryos derived from β-1,3 glucan-treated zebrafish were more resistant to bacterial challenge than control embryos. Moreover, the transferred C3 and Bf were directly associated with the antimicrobial defense of early embryos.

Expression of virus-responsive genes and their response to challenge with poly(I:C) at different stages of the annual fish Nothobranchius guentheri: Implications for an asymmetric decrease in immunity.

Aging deteriorates immunity. However, if aging affects immunity in an asymmetric or symmetric way remains largely unknown. In this study we clearly demonstrate that compared with adult fish, the anti-viral responses of aged annual fish Nothobranchius guentheri, as reflected by the expression levels of virus-responsive genes, including lgp2 and mda5 encoding sensor molecules, ifn-i and viperin encoding the effector molecules and irf1, irf7, stat1 and atf3 encoding the regulation elements, are either reduced remarkably or elevated markedly or show little difference depending upon the different tissues.
