Association between serum Galectin-3 and periodontitis in patients with type 2 diabetes mellitus.

Objectives: This study aims to investigate the correlation between serum Galectin-3 levels and the risk of periodontitis in patients with type 2 diabetes mellitus (T2DM).

Methods: A total of 140 patients with T2DM admitted to the endocrinology department of Weifang People's Hospital, Affiliated to Weifang Medical College from July 2021 to November 2022 were selected and divided into T2DM without periodontitis group (T2DM group, =67) and T2DM with periodontitis group (T2DMP group, =73) according to whether they were combined with periodontitis. In the same period, 65 non-periodontitis volunteers with normal blood glucose were selected as healthy control group (NC group).

Bilobalide attenuates lipopolysaccharide‑induced HepG2 cell injury by inhibiting TLR4‑NF‑κB signaling via the PI3K/Akt pathway.

Inflammation is involved in the pathological process underlying a number of liver diseases. Bilobalide (BB) is a natural compound from leaves that was recently demonstrated to exert hepatoprotective effects by inhibiting oxidative stress in the liver cancer cell line HepG2. The anti-inflammatory activity of BB has been reported in recent studies.

Structural characteristics and immune-enhancing activity of fractionated polysaccharides from Athyrium Multidentatum (Doll.) Ching.

Polysaccharides coded as CP were extracted from Athyrium Multidentatum (Doll.) Ching and then fractionated into five fractions (FP-1, FP-2, FP-3, FP-4 and FP-5). A purified polysaccharide designated as FP-3-4 was prepared from FP-3 by Sephadex G-100 column chromatography.

Nanosized FeS/ZnS heterojunctions derived using zeolitic imidazolate Framework-8 (ZIF-8) for pH-universal oxygen reduction and High-efficiency Zn-air battery.

Low-cost, stable, and highly active electrocatalysts for oxygen reduction reaction (ORR), especially for pH-universal ORR, are vital for developing numerous renewable energy devices. Herein, a hierarchical N, S-codoped porous carbon-based catalyst (ZFP-800) coupled with abundant FeS/ZnS heterojunctions was facilely prepared via direct pyrolysis of a Ferrocene-crosslinked pyrrole hydrogel composited with zeolitic imidazolate framework-8 (ZIF-8) templates. Compared with the heterojunction-free catalytic activity, the ZFP-800 catalytic activity was significantly higher in pH-universal ranges.

A mitochondria-targeted near-infrared fluorescent probe for imaging viscosity in living cells and a diabetic mice model.

A mitochondria-targeted near-infrared fluorescent probe NIR-V with 700 nm emission was designed to monitor cell viscosity changes with high selectivity and sensitivity, which was applied to detect the intracellular viscosity and image pancreatic tissue in a diabetic mouse model. Probe NIR-V provides an effective way to diagnose viscosity related diseases.

Chemical characteristics and cytoprotective activities of polysaccharide fractions from Athyrium Multidentatum (Doll.) Ching.

Five polysaccharide fractions (PS-1, PS-2, PS-3, PS-4 and PS-5) were successfully isolated from Athyrium Multidentatum (Doll.) Ching by anion-exchange column chromatography. Their in vitro cytoprotective activities and the underlying mechanisms were explored in this paper.

Neurophysiological mechanisms of bradykinin-evoked mucosal chloride secretion in guinea pig small intestine.

Aim: To investigate the mechanism for bradykinin (BK) to stimulate intestinal secretomotor neurons and intestinal chloride secretion.

Methods: Muscle-stripped guinea pig ileal preparations were mounted in Ussing flux chambers for the recording of short-circuit current (Isc). Basal Isc and Isc stimulated by BK when preincubated with the BK receptors antagonist and other chemicals were recorded using the Ussing chamber system.

Hypotensive and Angiotensin-Converting Enzyme Inhibitory Activities of Eisenia fetida Extract in Spontaneously Hypertensive Rats.

Objectives. This study aimed to investigate the antihypertensive effects of an Eisenia fetida extract (EFE) and its possible mechanisms in spontaneously hypertensive rats (SHR rats). Methods.

Inhibition of leucine aminopeptidase 3 suppresses invasion of ovarian cancer cells through down-regulation of fascin and MMP-2/9.

Leucine aminopeptidase 3 (LAP3) is a cell surface aminopeptidase that catalyzes the hydrolysis of leucine residues from the amino termini of protein or peptide substrates. The over-expression of LAP3 correlates with prognosis and malignant development of several human cell carcinomas. However, the molecular mechanism remains unknown.

Astragalus Polysaccharide Protects Astrocytes from Being Infected by HSV-1 through TLR3/NF-κB Signaling Pathway.

Astragalus polysaccharide (APS) is the most immunoreactive substance in Astragalus. APS can regulate the body's immunity and is widely used in many immune related diseases. However, till now, there is little information about its contribution to the protection of astrocytes infected by virus.

[Inhibitory effect of Astragalus polysaccharides on apoptosis of pancreatic beta-cells mediated by Fas in diabetes mellitus rats].

Objective: To observe the effects of Astragalus polysaccharides (APS) on the BG, insulin and C-peptide in serum, ultrastructure and Fas expression of pancreatic beta-cells in diabetes mellitus (DM) rats.

Methods: Thirty DM rats induced by streptozotocin (STZ) were randomly divided into three groups: DM group, APS 200 mg/kg group, APS 400 mg/kg group, another 10 normal rats were taken as the control group. The drug was given by intraperitoneal for 6 weeks.
