School of Economics, Beijing Institute of Technology, Beijing, China; GUST Center for Sustainable Development (CSD), Gulf University for Science and Technology, Hawally, Kuwait; University of Economics and Human Science in Warsaw, Warsaw, Poland. Electronic address:

This study analyses the influence of environmental taxes, renewable energy, economic growth, green innovation and financial development on environmental sustainability in G-20 countries from 1990 to 2022. To this end, the Method of Moments Quantile Regression (MMQR) was applied to obtain the reference results, complemented with Fully Modified Ordinary Least Square (FMOLS) and Driscoll-Kraay techniques to perform a comparative analysis. Our results confirm a negative relationship between environmental taxes and sustainability in all quantiles, although this relationship is only significant in the middle and upper quantiles.

Background: Accurate distinction between stroke etiologic subtypes is critical for physicians to provide tailored treatment. The triglyceride-glucose (TyG) index, a marker of insulin resistance, has been associated with stroke risk but its role in distinguishing stroke etiologic subtypes remains unclear. We aimed to assess the TyG index's ability to differentiate cardioembolic (CE) from non-cardioembolic (NCE) strokes.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.

To identify the incidence of injury time-out due to field injuries in highest level professional football (soccer) international tournaments and to compare the features of these incidents between men's and women's football. The incidence of stoppage time due to incidents and the resulting injury characteristics of professional football players participating in the 2018 FIFA Men's World Cup (MWC) in Russia and the 2019 FIFA Women's World Cup (WWC) in France were examined retrospectively through video analysis. In the 2018 MWC, a total of 123 injury time-outs with 132 treatments occurred in 64 matches, while in the 2019 WWC, 142 incidents with 150 injured players were recorded in 52 matches.

This study aimed to characterize match peak speeds, during a 20-second time window (10 seconds immediately before and after the match peak speed), in soccer matches. Twenty elite soccer players were monitored with global navigation satellite system (GNSS) devices during six soccer matches from the Brazilian first division. After identifying the peak speed, individual speeds within 10 seconds before and 10 seconds after were collected at each 0.

Incident reporting in Emergency Medical Services (EMS) is vital for enhancing patient safety and system performance, but time constraints often impede efficient documentation. Hamad Medical Corporation Ambulance Service Group (HMCASG) implemented a streamlined "Occurrence, Variance, and Accident" (OVA) reporting system to address these challenges. This study evaluated the effectiveness of this system in reducing incident report completion time.

Octadecaneuropeptide promotes the migration of astrocyte via ODN metabotropic receptor and calcium signaling pathway.

Peptides

January 2025

University of Tunis El Manar, Faculty of Sciences of Tunis, LR18ES03 Laboratory of Neurophysiology, Cellular Physiopathology and Biomolecules Valorisation. 2092 Tunis, Tunisia.

Migration is an essential characteristic of cells that occurs during many physiological and pathological processes. Astrocytes represent the most abundant cell type in the adult central nervous system (CNS), that play a crucial role in various functions such as guiding and supporting neuronal migration during development and maintaining brain homeostasis at adulthood. Astrocytes specifically synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN).

Scabiosa artropurperea, a member of the Dipsacaceae family and Scabiosa genus, is renowned for its medicinal properties. In the present study, we investigated the impact of Scabiosa artropurperea aqueous extract (AES) on the in vivo reproductive functions in Queue Fine de l'Ouest ewes, and on in vitro ovine granulosa cells. Ewes were synchronized for 14 days with intra-vagina progesterone (P4) devices (FGA, 20 mg) and divided into four groups receiving daily oral doses of 0, 1, 2, and 4 mg of AES/kg Live Body Weight (LBW), respectively.

This work explores two methods to encapsulate Thymoquinone (TQ) into lipid nanocapsules (LNCs) for oral administration. TQ was added during the phase inversion temperature method (TQ-LNCs-1) or to unload LNCs dispersion (TQ-LNCs-2). LNCs were evaluated for mean diameter, polydispersity index (PDI), ζ-potential, drug loading (DL), drop tensiometer, storage stability, stability in simulated gastrointestinal fluids (SGIF), and intestinal permeability across Caco-2 cells.
