Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

Food Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values

Reassessment of the roles of the peritrophic envelope and hydrolysis in protecting polyphagous grasshoppers from ingested hydrolyzable tannins [PDF]

, 1996
We examined several of the mechanisms that have been reported to enable polyphagous grasshoppers (Orthoptera: Acrididae) to tolerate ingested hydrolyzable tannins: hydrolysis, adsorption on the peritrophic envelope, and peritrophic envelope ...

DNA Breakage by Hydrolyzable Tannins in the Presence of Cupric Ion

Agricultural and Biological Chemistry, 1985
DNA breakage by hydrolyzable tannins of known structures was investigated by agarose or polyacrylamide gel electrophoretic analysis. Hydrolyzable tannins could cause both double-strand and single-strand breakages in λDNA in the presence of Cu2+. The breaking reaction was strongly suppressed at concentrations higher than 100 μm of hydrolyzable tannins ...
