Effectiveness analysis of deceleration capacity and traditional heart rate variability in diagnosing vasovagal syncope.

Background: Vasovagal syncope (VVS) is a prevalent medical condition with a lack of efficient methods for its detection.

Aim: This study aimed to explore an objective clinical indicator in diagnosing VVS.

Methods: The retrospective analysis involved clinical data of 243 syncope patients from 1 June 2020 to 31 July 2023.

Fabricating Ultrastrong Carbon Nanotube Fibers via a Microwave Welding Interface.

Liquid crystal wet-spun carbon nanotube fibers (CNTFs) offer notable advantages, such as precise alignment and scalability. However, these CNTFs usually suffer premature failure through intertube slippage due to the weak interfacial interactions between adjacent shells and bundles. Herein, we present a microwave (MW) welding strategy to enhance intertube interactions by partially carbonizing interstitial heterocyclic aramid polymers.

Irisin alleviates hyperoxia-induced bronchopulmonary dysplasia through activation of Nrf2/HO-1 pathway.

Background: Bronchopulmonary dysplasia (BPD) is a common pulmonary injury among premature infants, which is often caused by hyperoxia exposure. Irisin is a novel hormone-like myokine derived mainly from skeletal muscles as well as adipose tissues. Many studies have indicated that Irisin exert a variety of properties against hyperoxia-induced inflammation and oxidative stress (OS).

Value of red blood cell distribution width in prediction of diastolic dysfunction in cirrhotic cardiomyopathy.

Background: Clinical diagnosis of cirrhotic cardiomyopathy (CCM) often encounters challenges of lack of timeliness and disease severity, with the commonly positive indicator usually associated with advanced heart failure.

Aim: To explore suitable biomarkers for early CCM prediction.

Methods: A total of 505 eligible patients were enrolled in this study and divided into four groups according to Child-Pugh classification: Group I, Class A without CCM (105 cases); Group II, Class A with CCM (175 cases); Group III, Class B with CCM (139 cases); and Group IV, Class C with CCM (86 cases).

The Stiffest and Strongest Predicted Material: C N Atomic Chains Approach the Theoretical Limits.

Though linear atomic chains exhibit extreme properties, it is presently unclear how these properties can be maximized by the choice of elemental composition. Considering that boron, carbon, and nitrogen can form high modulus and high strength atomic chains, here an algorithm is developed to construct 143 possible atomic chains of these elements with 6 or fewer atoms in the primitive cell and explore their stabilities and mechanical properties by first-principles calculations. It is found that the gravimetric modulus (1032 GPa g cm ) and strength (108 GPa g cm ) of the C N chain significantly exceed those of any known material, including the previously stiffest predicted material (C chain, 945 GPa g cm ) and the previously strongest predicted material (BC chain, 92 GPa g cm ), and also approach the theoretical limits of gravimetric modulus (1036 GPa g cm ) and strength (130 GPa g cm ).

The Early Predictive Value of Circulating Monocytes and Eosinophils in Coronary DES Restenosis.

Background: Monocytes and eosinophils are involved in intracoronary inflammatory responses, aggravating coronary artery plaque instability and in-stent restenosis (ISR).

Aims: To investigate an early prediction of ISR in patients undergoing stenting by circulating monocytes and eosinophils.

Methods: The single-center data of patients undergoing successful drug-eluting stents (DES) implantation from January 1, 2017 to April 30, 2020 were retrospectively analyzed.

Clinical efficacy and safety of tirofiban combined with conventional dual antiplatelet therapy in ACS patients undergoing PCI.

Challenges remain for clinicians over balancing the efficacy of active antithrombotic therapy and simultaneous bleeding reduction in patients. The clinical data of 347 patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) were retrospectively analyzed. On the basis of the given tirofiban, the patients were assigned into three different dose groups: high dose group (group H), medium dose group (group M), and low dose group (group L).
