Aging is an important process to improve the quality of cigar, but the effect of aging with media on cigar has not been reported.Therefore, this study aimed to prepare different aging media and clarify the influence of media on cigar quality. Effective media were first screened by sensory evaluation, then the effects of aging media on the chemical composition and microbial community of cigar were investigated. The results showed that: 1) As aging media, coffee formula and cocoa formula could optimize the smoke and aroma characteristics of cigar, and 30 days was the appropriate period for cigar aging. 2) Aging with coffee or cocoa media could increase the content of amino acids, non-volatile organic acids, malic acid and aroma components. Particularly, the content of aroma components increased from 2.48 mg g (W-30) to 3.21 mg g (C-30) and 3.70 mg g (K-30), respectively. 3) Aging with coffee can improve the diversity of bacteria and fungi on the cigar surface and change the succession rule of bacterial community. In contrast, aging with cocoa had no significant effect on microbial diversity of cigar. In this study, the influence of aging media on cigar quality was analyzed multidimensionally for the first time, which provided a reference for the development of new aging media and technologies to improve cigar quality.

A method to quantitate the stabilization of Mitochondria-Associated endoplasmic reticulum Membranes (MAMs) in a 3-dimensional (3D) neural model of Alzheimer's disease (AD) is presented here. To begin, fresh human neuro progenitor ReN cells expressing β-amyloid precursor protein (APP) containing familial Alzheimer's disease (FAD) or naïve ReN cells are grown in thin (1:100) Matrigel-coated tissue culture plates. After the cells reach confluency, these are electroporated with expression plasmids encoding red fluorescence protein (RFP)-conjugated mitochondria-binding sequence of AKAP1(34-63) (Mito-RFP) that detects mitochondria or constitutive MAM stabilizers MAM 1X or MAM 9X that stabilize tight (6 nm ± 1 nm gap width) or loose (24 nm ± 3 nm gap width) MAMs, respectively.

Introduction: The objective of the present study was to improve the anti-inflammatory and antibacterial activities of mastic gum resin (MGR). MGR was loaded into a phospholipid nanocarrier with or without partially hydrolyzed ginsenoside, followed by dispersion into distilled water.
Method: The phospholipid nanocarrier dispersion showed significantly enhanced in-vitro release, porcine skin/ intestine permeation, and retention.
Mindfulness Intervention for Health Information Avoidance in Older Adults: Mixed Methods Study.

Background: The global aging population and rapid development of digital technology have made health management among older adults an urgent public health issue. The complexity of online health information often leads to psychological challenges, such as cyberchondria, exacerbating health information avoidance behaviors. These behaviors hinder effective health management; yet, little research examines their mechanisms or intervention strategies.
