Gut microbiota: an overlooked factor that plays a significant role in osteoporosis

open access: yesJournal of International Medical Research, 2019
Gut microbes are known as the body’s second gene pool. Symbiotic intestinal bacteria play a major role in maintaining balance in humans. Bad eating habits, antibiotic abuse, diseases, and a poor living environment have a negative effect on intestinal ...

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

open access: yesAdvanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Innovative Integration of Layered Carbon Materials in Biopolymer Fibrous Membranes for Sustainable Water Treatment

open access: yesAdvanced Sustainable Systems, EarlyView.
This review explores the progressive design of biopolymer‐based fibrous membranes enhanced with layered carbon materials such as MXene, graphene oxide, and carbon nanotubes. It highlights how their integration significantly boosts water filtration performance, selectivity, and antifouling properties.

Capsule Endoscopy Image Enhancement for Small Intestinal Villi Clarity [PDF]

open access: yesarXiv
This paper presents, for the first time, an image enhancement methodology designed to enhance the clarity of small intestinal villi in Wireless Capsule Endoscopy (WCE) images. This method first separates the low-frequency and high-frequency components of small intestinal villi images using guided filtering.

HARMLESS Early Warning System for Advanced Materials

open access: yesAdvanced Sustainable Systems, EarlyView.
The HARMLESS Early Warning System tackles Advanced Materials (AdMa) risk governance by providing a framework, organised in two tiers, underpinned with methods/tools to support risk assessors in the pre‐assessment preceding risk assessment. It allows for initial screening to identify AdMa with concerns considering exposure, hazards, sustainability and ...
