Controlled bioreduction of silver ions to nanosized particles on a porous magnetic-biopolymer of carboxymethyl cellulose, FeO/CMC-Ag NPs, serving as a sustainable nanocatalyst.

A magnetic-biopolymer composite of carboxymethyl cellulose (CMC), designated as FeO@CMC, was synthesized featuring remarkable stability and an active surface with a green biosynthetic method. This composite was engineered to serve as a substrate for stabilizing silver nanoparticles (Ag NPs) with enhanced functional properties. The catalytic efficacy of the nanocatalyst, incorporating Ag NPs at concentrations of 3%, 7%, and 10%, was evaluated for the reduction of the toxic compound 4-nitrophenol to the beneficial 4-aminophenol.

Individualized evaluation of the total dose received by radiotherapy patients: Integrating in-field, out-of-field, and imaging doses.

Purpose: To propose a methodology for integrating the out-of-field and imaging doses to the in-field dose received by radiotherapy (RT) patients. In addition, the impact of considering the total dose in planning and radiation-induced second malignancies (RISM) risk assessment will be evaluated in several scenarios comprising photon and proton treatments.

Methods: The total dose is the voxel-wise sum of the doses from the different radiation sources (accounting for the radiobiological effectiveness) produced during the whole RT chain.

Diversity in the Clinical Course and Outcome of COVID-19 in Patients with Different Inborn Errors of Immunity can be Associated with the Type of Error.

Background: The relationship between inborn errors of immunity (IEIs) and COVID-19 severity and incidence rates remains unclear due to limited and diverse data. This study aimed to address this gap by identifying specific IEIs associated with an increased risk of severe COVID-19 or a predisposition to severe disease before vaccination.

Materials And Methods: Data were collected from the medical records of 15 patients with various IEIs, supplemented by interviews with individuals from an IEIs registry who had experienced COVID-19 before vaccination.

Chia seed supplementation and inflammatory biomarkers: a systematic review and meta-analysis.

Chia seeds have gained attention for their potential anti-inflammatory properties, which may be attributed to their high content of omega-3 fatty acids, dietary fibre, and antioxidants. This study aims to provide an overview of the current understanding regarding the effects of chia seeds on inflammatory markers, specifically C-reactive protein (CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-α). A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, Cochrane, and Google Scholar up to June 2024.
