Association between serum 25-hydroxyvitamin D and fasting blood glucose in osteoporosis patients.

Osteoporosis (OP) is often associated with other complications, such as impaired glucose homeostasis. Vitamin D deficiency is common and has been linked to bone metabolism and the regulation of blood sugar levels. The aim of this study was to evaluate the independent relationship between serum 25-hydroxyvitamin D (25[OH]D) and fasting blood glucose levels (FBG) in a group of patients diagnosed with OP.

Association between serum uric acid levels and bone mineral density in patients with osteoporosis: a cross-sectional study.

Background: The results of studies exploring the association between serum uric acid (SUA) and bone mineral density (BMD) have been controversial and inconsistent. We thus sought to explore whether SUA levels were independently associated with BMD in patients with osteoporosis (OP).

Methods: This cross-sectional analysis was conducted using prospectively obtained data from the Affiliated Kunshan Hospital of Jiangsu University database pertaining to 1,249 OP patients that were hospitalized from January 2015 - March 2022.

Sea surface pCO in an urbanized coastal system (Jiaozhou Bay, China) during summer.

Various biogeochemical processes complicate carbon dioxide (CO) behaviour in coastal oceans. Through eight summer surveys, detailed variations in CO mechanisms in the urbanized Jiaozhou Bay, China, were analysed. During the rainless period, respiration and dissolved inorganic carbon input from treated wastewater made the northeastern region a strong CO source, while the western region with cleaner seawater was a weak source because calcium carbonate (CaCO) precipitation exceeded primary production.

Variations in dissolved inorganic carbon species in effluents from large-scale municipal wastewater treatment plants (Qingdao, China) and their potential impacts on coastal acidification.

With rapid development of global wastewater treatment plants (WWTPs), acidification and enhanced CO release in receiving waters caused by high-CO treated wastewater input have raised concerns. Insights into the variations in dissolved inorganic carbon (DIC) species in treated wastewater contribute to understanding the mechanisms of the acidification process. Here, we investigated three large-scale municipal WWTPs that discharged into the coast of Qingdao, China, for variations in effluent DIC species and their control mechanisms.

Effect of patchouli alcohol on Helicobacter pylori-induced neutrophil recruitment and activation.

Neutrophil infiltration typically occurs in Helicobacter pylori (H. pylori)-induced acute gastritis; however, this immune response fails to eradicate H. pylori in vivo.

A robust polyoxometalate-templated four-fold interpenetrating metal-organic framework showing efficient organic dye photodegradation in various pH aqueous solutions.

A Keggin-type polyoxometalate (POM)-templated metal-organic framework, [Cd(TTPB-4)(DMF)3]4[PMo12O40]2[HPMo12O40]·6DMF·4H2O (1), based on a newly designed linker of TTPB-4 [TTPB-4 = 1,3,5-tris(4-(4H-1,2,4-triazol-4-yl)phenyl)benzene], has been hydrothermally synthesized and characterized using IR, XRD, TGA, UV-Vis and photoluminescence spectra. Single-crystal X-ray crystallography reveals that 1 represents a unique POM-templated four-fold interpenetrated 3-D coordination network. The POM-templated MOF of 1 exhibits strong chemical stability that can withstand aqueous solutions of various pH-values (2-10).

Syntheses, structures, and magnetic properties of two unique Cu(ii)-based coordination polymers involving a crystal-to-crystal structural transformation from a 1D chain to a 3D network.

Two new coordination polymers, Cu(Hbsal)(4,4'-bpy) (1) and Cu(bsal)(4,4'-bpy)·DMF (2), have been synthesized from 5-bromosalicylic acid (Hbsal) and the auxiliary ligand 4,4'-bipyridine (4,4'-bpy) through a slow diffusion method. Compound 1 is composed of parallel 1D linear chains, whereas compound 2 represents a non-interpenetrated 3D sod net which is constructed from left and right-handed helical chains alternately separated by 4,4'-bpy. The most interesting finding is that compound 1 can be irreversibly transformed into 2 in a crystal-to-crystal manner in the case that compound 1 is immersed in the DMF solvent.

Diffusion kurtosis MRI versus conventional diffusion-weighted imaging for evaluating inflammatory activity in Crohn's disease.

Purpose: To assess the efficacy of diffusion kurtosis imaging (DKI) and to compare DKI-derived parameters with that of conventional diffusion-weighted imaging (DWI) for grading the inflammatory activity of Crohn's disease (CD).

Materials And Methods: In all, 38 patients with CD underwent 3T magnetic resonance enterography (MRE) with DKI (b values of 0-2000 s/mm ). The inflammatory activity of the bowel segments was graded by magnetic resonance index of activity (MaRIA) as inactive (<7), mild (≥7 and <11), or moderate-severe (≥11).

Diffusion-weighted MRI Enables to Accurately Grade Inflammatory Activity in Patients of Ileocolonic Crohn's Disease: Results from an Observational Study.

Background: Diffusion-weighted imaging (DWI) is a novel technique to evaluate bowel inflammation in Crohn's disease (CD). It remains unclear whether DWI could differentiate grades of inflammation activity and add to the accuracy of conventional magnetic resonance enterography (MRE) in defining disease activity. We aimed to assess the accuracy of DWI for evaluating ileocolonic CD inflammation compared with conventional MRE, using ileocolonoscopy as reference standard.

A unique 3D metal-organic framework based on a 12-connected pentanuclear Cd(II) cluster exhibiting proton conduction.

Solvothermal reaction of a TCA (TCA = 4,4',4''-tricarboxytriphenylamine) ligand with Cd(NO3)2 yielded a unique 3D 12-connected metal-organic framework of , which can be simplified as a (3,3,12)-connected 3-nodal net with a Schläfli symbol of {4(16)·6(36)·8(14)}{4(2)·6}2{4(3)}2 based on a 12-connected node of a pentanuclear Cd(ii) cluster and a three-connected organic linker of TCA. Compound exhibits both photoluminescence and proton conductivity. The luminescence properties of originate from the triphenylamine chromophore of the TCA ligand.

Decreased CD200R expression on monocyte-derived macrophages correlates with Th17/Treg imbalance and disease activity in rheumatoid arthritis patients.

Objectives: CD200 is expressed on various cell types, including T cells, while the CD200 receptor (CD200R) is expressed on myeloid cells such as monocytes-derived macrophages (MDMs). The CD200-CD200R interaction has been shown to play an important role in the prevention of autoimmune disease. Thus, we hypothesized that CD200/CD200R1 is involved in the pathogenesis of rheumatoid arthritis (RA).
