Frontiers of Plant-derived Exosomes from Research Methods to Pharmaceutical Applications in Plant-based Therapeutics.

Exosomes have emerged as critical mediators of intercellular communication and various physiological processes between cells and their environment. These nano-sized vesicles have been extensively investigated and confirmed to exhibit multifunctionality in animal systems. In particular, they participate in intercellular signaling, influence disease progression, and exhibit biological activity.

Network meta-analysis of multiple doses of vonoprazan for the treatment of erosive esophagitis.

20 mg of vonoprazan (VPZ20) is recommended in most countries to treat erosive esophagitis (EE). Whether other doses of vonoprazan, such as 5 mg (VPZ5), 10 mg (VPZ10), 20 mg (VPZ20), and 40 mg (VPZ40) are more effective is unknown. Three databases were electronically searched to identify studies published before November 2021.

A Lamb Waves Based Ultrasonic System for the Simultaneous Data Communication, Defect Inspection, and Power Transmission.

Lamb-wave-based structural health monitoring (SHM) has attracted extensive attention in recent years. This article aims to realize the functions of data communication, defect detection, and energy transmission through piezoelectric transducers. In this work, the S mode at 500 kHz and the A mode at 150 kHz are selected as the carrier waves and the optimized excitation frequencies are determined through analytical investigation and frequency sweeping experiments.

Enhanced oral delivery and anti-gastroesophageal reflux activity of curcumin by binary mixed micelles.

The aim of this study was to improve the solubility, oral bioavailability, and anti-gastroesophageal reflux activity of curcumin (CM) by preparing two CM-loaded, novel, binary mixed micelles (CM-M). The two CM-M were prepared by ethanol thin-film hydration method. One (CM-T) was prepared using D-alpha-tocopheryl polyethylene glycol 1000 succinate and SolutolHS15, and the other (CM-F) was prepared using PluronicF127 and SolutolHS15.

Airway hyperresponsiveness induced by repeated esophageal infusion of HCl in guinea pigs.

Gastroesophageal reflux is a common disorder closely related to chronic airway diseases, such as chronic cough, asthma, chronic bronchitis, and chronic obstructive disease. Indeed, gastroesophageal acid reflux into the respiratory tract causes bronchoconstriction, but the underlying mechanisms have still not been clarified. This study aimed to elucidate functional changes of bronchial smooth muscles (BSMs) isolated from guinea pigs in an animal model of gastroesophageal reflux.

Preparation and evaluation of berberine alginate beads for stomach-specific delivery.

The purpose of this research was to prepare floating calcium alginate beads of berberine for targeting the gastric mucosa and prolonging their gastric residence time. The floating beads were prepared by suspending octodecanol and berberine in sodium alginate (SA) solution. The suspension was then dripped into a solution of calcium chloride.

Electrical characteristics and photocurrent spectral response of Si nanowires p-i-n junctions.

P-i-n junctions were fabricated along Si nanowires (SiNWs) via the conventional top-down approach using optical lithography. Each device comprises 500 identical SiNWs connected in parallel, and each SiNW has triangular cross-section with dimensions of ~6 nm (base) by ~8 nm (height). The photodiodes exhibit very good rectifying electrical characteristics with a low reverse bias current of ~0.
