Effects of household solid fuel use on sarcopenia in middle-aged and older adults: evidence from a nationwide cohort study.

Background: Household solid fuel use is common in global households and has been linked to changes in handgrip strength and muscle mass. However, whether household solid fuel use results in sarcopenia over time is not well elaborated.

Methods: This study employed data from the 2011-2015 China Health and Retirement Longitudinal Study (CHARLS) that recruited 4,932 participants ≥45 years.

The levels of serum lipoprotein(a) on clinical outcomes in Chinese hospitalized patients with cardiovascular diseases.

Objective: Serum lipoprotein(a) [Lp(a)] is a risk factor of cardiovascular diseases. However, the relationship between the serum Lp(a) and clinical outcomes has been seldom studied in Chinese hospitalized patients with cardiovascular diseases.

Methods: We retrospectively collected the clinical data of hospitalized patients with cardiovascular diseases in the Cardiovascular Department of Dongguan People's Hospital from 2016 to 2021 through the electronic case system.

Thyroid dysfunction in nonvalvular atrial fibrillation and clinical outcomes.

Background: Thyroid dysfunction's effects on those who have been diagnosed with atrial fibrillation have not been well investigated. We looked at how thyroid function among patients with pre-existing atrial fibrillation related to thromboembolic risk and clinical outcomes.

Methods: We gathered the medical information of patients diagnosed with nonvalvular atrial fibrillation (NVAF) between 2016 and 2020 at Dongguan People's Hospital.

Preparation and bifunctional properties of the A-site-deficient SrTiFeNiO perovskite.

The development of efficient, non-noble metal electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is crucial for their application in energy storage devices, such as fuel cells and metal-air batteries. In this study, SrTiFeNiO (STFN) perovskite was synthesized using the sol-gel method, and its electrocatalytic activity was evaluated using a rotating disk electrode (RDE) in an alkaline medium. STFN synthesized at the optimum synthesis temperature of 800 °C exhibited good ORR and OER performances.

Validation of plasma D-dimer in Chinese patients with acute non-ST segment elevation myocardial infarction.

Objective: To analyze the predictive values of D-dimer in Chinese patients with non-ST-segment elevation myocardial infarction (NSTEMI).

Methods: We retrospectively retrieved consecutive patients hospitalized due to acute NSTEMI from January 2015 to December 2018 from the Electronic Medical Record (EMR) library. Clinical and follow-up data were collected.

Pneumatic Bionic Hand with Rigid-Flexible Coupling Structure.

This paper presents a rigid-flexible composite of bionic hand structure design scheme solution for solving the problem of low load on the soft gripping hand. The bionic hand was designed based on the Fast Pneumatic Network (FPN) approach, which can produce a soft finger bending drive mechanism. A soft finger bending driver was developed and assembled into a human-like soft gripping hand which includes a thumb for omnidirectional movement and four modular soft fingers.

Prevalence and impact of fibrinolytic dysregulation in patients with acute coronary syndromes.

Objective: Dual antiplatelet therapy can reduce coronary thrombosis and improve the prognosis in patients with acute coronary syndrome (ACS). However, there was limited prognostic information about fibrinolytic dysregulation in patients with ACS. This study is aimed to evaluated the prevalence and impact of fibrinolytic dysregulation in patients with acute coronary syndrome (ACS).

Whole blood dynamic platelet aggregation counting and 1-year clinical outcomes in patients with coronary heart diseases treated with clopidogrel.

In the setting of coronary heart diseases (CHDs) on treatment with clopidogrel, ADP-induced platelet aggregation has been demonstrated with ischemic events. However, there were very limited data for predicting ischemic events by platelet function test via dynamic platelet aggregation counting (DPAC). The present study aimed to evaluate the relationship between adenosine diphosphate (ADP)-induced whole blood platelet aggregation rates (PARs) and clinical outcomes in patients with CHDs on treatment with clopidogrel.

H∞ Robust Control of a Large-Piston MEMS Micromirror for Compact Fourier Transform Spectrometer Systems.

Incorporating linear-scanning micro-electro-mechanical systems (MEMS) micromirrors into Fourier transform spectral acquisition systems can greatly reduce the size of the spectrometer equipment, making portable Fourier transform spectrometers (FTS) possible. How to minimize the tilting of the MEMS mirror plate during its large linear scan is a major problem in this application. In this work, an FTS system has been constructed based on a biaxial MEMS micromirror with a large-piston displacement of 180 μm, and a biaxial H∞ robust controller is designed.

A new phenolic glycoside from Saprosma merrillii.

A new phenolic glycoside derivative, saproglucoside (1), along with five known phenolic glycoside derivatives (2-6) were isolated from the stems of Saprosma merrillii. The structure of the new compound 1 was determined by 1D and 2D NMR as well as by HRESIMS and hydrolysis. The inhibitory activities of all compounds against seven pathogenic bacteria and two cancer cell lines were evaluated.
