Dietary fatty acids and risk for Alzheimer's disease, dementia, and mild cognitive impairment: A prospective cohort meta-analysis.

The association between dietary fatty acid intake and Alzheimer's disease (AD), dementia, and mild cognitive impairment (MCI) risk is inconsistent. This meta-analysis examined the effect of dietary fatty acid intake in prospective cohort studies including patients with AD, dementia, and MCI. PubMed, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP Database were systematically searched through September 2020.

Construction of EVA/chitosan based PEG-PCL micelles nanocomposite films with controlled release of iprodione and its application in pre-harvest treatment of grapes.

A novel nanocomposite poly(ethylene-co-vinyl acetate) (EVA) film with controlled in vitro release of iprodione (ID) was prepared. Chitosan (CS) was used as the reinforcement which enhances the water and oxygen permeability of films. ID loaded poly(ethylene glycol)-poly(ε-caprolactone) (PEG-PCL) (IPP) micelles were used as the drug carrier which endows the films with antifungal and controlled release ability.

[Human umbilical cord mesenchymal stem cells with adenovirus-mediated interleukin 12 gene transduction inhibits the growth of ovarian carcinoma cells both in vitro and in vivo].

Objective: To study the inhibitory effect of human umbilical cord mesenchymal stem cells (UC-MSCs) infected by a adenoviral vector containing interleukin 12 (IL-12) gene on the proliferation of ovarian carcinoma SKOV3 in vitro and the growth of tumor explants in nude mice.

Methods: Cultured human UC-MSCs were infected with the recombinant adenovirus vector harboring IL-12 gene to establish the IL-12-expressing cell line AdIL-12-MSCs. Western blotting and RT-PCR were used to detect IL-12 expressions in AdIL-12-MSCs at the protein and mRNA levels, respectively.
