Background: Pulmonary fibrosis is a chronic and advancing interstitial lung disease, and there is an urgent need for novel agents for its therapy. Physalis Calyx seu Fructus (PCF) has been utilized in traditional Chinese medicine to treat respiratory disorders with a long history, however, the therapeutic effect and mechanism of PCF against pulmonary fibrosis are still unclear.

Purpose: To assess therapeutic efficacy and underlying mechanism of 75 % ethanol extract of PCF (PCF-EtOH) against pulmonary fibrosis, as well as to discover active constituents in PCF.

Tropilaelaps mercedesae, an ectoparasitic mite of honeybees, is currently a severe health risk to Apis mellifera colonies in Asia and a potential threat to the global apiculture industry. However, our understanding of the physiological and developmental regulation of this pest remains significantly insufficient. Using ultra-high resolution mass spectrometry, we provide the first comprehensive proteomic profile of T.

Fenazaquin, a potent insecticide widely used to control phytophagous mites, has recently emerged as a potential solution for managing Varroa destructor mites in honeybees. However, the comprehensive impact of fenazaquin on honeybee health remains insufficiently understood. Our current study investigated the acute and chronic toxicity of fenazaquin to honeybee larvae, along with its influence on larval hemolymph metabolism and gut microbiota.

Nitrogen-based heterocycles have aroused widespread interest due to their reoccurrence in many pharmaceuticals. Amongst these motifs, the enantioenriched lactams are the ubiquitous scaffolds found in myriad biologically active natural products and drugs. Recently, the transition metal-catalyzed asymmetric carbamoylation has been widely employed as a straightforward arsenal for chiral lactam architecture synthesis, including β-lactam and γ-lactam.

Reported herein is a palladium/copper cooperative-catalyzed dicarbofunctionalization of alkene-tethered carbamoyl chlorides with 1,1-diborylmethane. This cyclization/deborylation cascade strategy allows for the expedient formation of the versatile borylated 3,3-disubstituted oxindole skeleton, allowing for further functionalization via the derivatization of the carbon-boron bond.

The effect of plasma endostatin on cognitive impairment after ischemic stroke remains unclear. We conducted this study to explore the association between plasma endostatin in the acute phase of ischemic stroke and post-stroke cognitive impairment (PSCI). Baseline plasma endostatin levels were measured, and cognitive function status was assessed by Montreal cognitive assessment at 3 months among 613 ischemic stroke patients.

Transition metal-catalyzed carbonylation with carbon nucleophiles is one of the most prominent methods to construct ketones, which are highly versatile motifs prevalent in a variety of organic compounds. In comparison to the well-established palladium catalytic system, the nickel-catalyzed carbonylative coupling is much underdeveloped due to the strong binding affinity of CO to nickel. By leveraging easily accessible tert-butyl isocyanide as the CO surrogate, we present a nickel-catalyzed allylic carbonylative coupling with alkyl zinc reagent, allowing for the practical and straightforward preparation of synthetically important β,γ-unsaturated ketones in a linear-selective fashion with excellent trans-selectivity under mild conditions.

Background And Aims: Endostatin is implicated in the atherosclerosis process and serves as a promising cardiovascular biomarker, while its clinical significance in ischemic stroke patients remains unclear. We aimed to examine the association between endostatin and mortality and disability after ischemic stroke.

Methods: A total of 3463 acute ischemic stroke patients with measured plasma endostatin from the China Antihypertensive Trial in Acute Ischemic Stroke were included in this study.

Background: There was a lack of studies on the association between Human Cytomegalovirus (HCMV) infection and prognosis of ischemic stroke, although it was indicated that human cytomegalovirus DNA has played a role in several cardiovascular disorders.

Objective: To examine the association between HCMV IgM levels in the acute phase and death and major disability after 2 weeks of acute ischemic stroke.

Methods: Serum HCMV IgM levels were measured in 1150 participants in China.
