Associations of cystatin C with incident chronic kidney disease and all-cause mortality in patients with normal glucose tolerance and prediabetes.

We investigated the association of cystatin C with incident chronic kidney disease (CKD), defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m. We enrolled patients with an eGFR ≥ 60 mL/min/1.

Chiral Aldehyde/Palladium Catalysis Enables Asymmetric Branched-Selective Ring-Opening Functionalization of Methylenecyclopropanes with Amino Acid Esters.

Achieving catalytic asymmetric functionalization of methylenecyclopropanes (MCPs) by selective C-C bond cleavage is a notable challenge due to the intricate reaction partners involved. In this work, we report that chiral aldehyde/palladium combined catalysis enables the asymmetric functionalization of MCPs with NH-unprotected amino acid esters. This reaction proceeds through a regiospecific branched ring-opening mechanism, resulting in optically active α,α-disubstituted α-amino acid esters bearing nonconjugated terminal alkene units.

Enhancing Absorption Performance of CO by Amine Solution through the Spiral Wired Channel in Concentric Circular Membrane Contactors.

The CO absorption rate by using a Monoethanolamide (MEA) solution through the spiral wired channel in concentric circular membrane contactors under both concurrent-flow and countercurrent-flow operations was investigated experimentally and theoretically. The one-dimensional mathematical modeling equation developed for predicting the absorption rate and concentration distributions was solved numerically using the fourth Runge-Kutta method under various absorbent flow rate, CO feed flow rate and inlet CO concentration in the gas feed. An economical viewpoint of the spiral wired module was examined by assessing both absorption flux improvement and power consumption increment.

[Clinical and genetic features of limb-girdle muscular dystrophy type 1B: a case report].

This article reports a case of limb-girdle muscular dystrophy type 1B (LGMD1B) caused by a novel splicing heterozygous mutation in the LMNA gene. The proband presented with progressive aggravation of weakness in walking. There was no atrophy of the scapular muscles and the lower-extremity proximal muscles, with normal muscle tension of the extremities, grade 4 muscle strength in the upper and lower extremities, and positive Gower sign.

Creating a pseudometallic state of K+ by intercalation into 18-crown-6 grafted on polyfluorene as electron injection layer for high performance PLEDs with oxygen- and moisture-stable Al cathode.

Polymer light-emitting diodes (PLEDs) suffer from inadequate lifetimes because of the use of environmentally sensitive metals as the cathodes. We present the use of water/methanol-soluble polyfluorene grafted with 18-crown-6 chelating to K(+) as the electron-injection layer (EIL) for deep-blue-emission PLEDs, allowing the use of environmentally stable Al as the cathode since electron donation from the 18-crown-6 can reduce K(+) to a stable "pseudometallic state", enabling it to act as an intermediate step for electron injection. Furthermore, when poly(ethylene oxide) was blended into the EIL to provide hole blocking (HB), the device exhibited the highest performance reported to date for a deep-blue-emission PLED based on a conjugated polymer as the emitting layer, with a brightness of 54,800 cd/m(2) and an external quantum efficiency of 5.

Extract isolated from Angelica hirsutiflora with insulin secretagogue activity.

Ethnopharmacological Relevance: Angelica genus (Umbelliferae) has traditionally been used as the medicine and health food considered alleviating several disorders including diabetes mellitus. Angelica hirsutiflora Liu Chao & Chuang is an endemic species and a folk medicine in Taiwan.

Aim Of The Study: The scientific evidence of anti-diabetic effect for Angelica hirsutiflora remains unknown.
