Alpha,omega-hydrogen donor/acceptor functional polymer strands are prepared via a combination of living radical polymerization and orthogonal conjugation and subsequently self-assembled as single chains to emulate--on a simple level--the self-folding behaviour of natural biomacromolecules.

This study successfully synthesised and characterised composites combining chitosan (CH), carboxymethyl cellulose (CMC), and various flavonoids (Fla). This innovative approach demonstrates the potential for developing functional materials with antioxidant and food preservation properties. The composites CH-Fla-CMC (1-5) was characterised using advanced techniques such as FT-IR, UV-Vis, XRD, SEM, TEM, and TGA, providing robust data on their structural, morphological, and thermal properties.

: Cold atmospheric plasma (CAP) has been demonstrated as an adjustable device to generate various combinations of short-lived reactive oxygen and nitrogen species (RONS) and as a promising appliance for cancer therapy. This study investigated the effects of direct and indirect treatments of Argon-based CAP to cancer cells (A2058, A549, U2OS and BCC) and fibroblasts (NIH3T3 and L929) on cell viability. We also aimed to understand whether plasma-generated RONS were involved in this process using genetic evidence.

Epidemiological studies have suggested that following long-term, low-dose daily aspirin (LTLDA) administration for more than 5 years at 75-100 mg/day, 20-30% of patients (50-80 years old) had a lower risk of developing colorectal cancer (CRC) and about the same proportion in developing iron deficiency anemia (IDA). In cases of IDA, an increase in iron excretion is suspected, which is caused by aspirin chelating metabolites (ACMs): salicylic acid, salicyluric acid, 2,5-dihydroxybenzoic acid, and 2,3-dihydroxybenzoic acid. The ACMs constitute 70% of the administered aspirin dose and have much longer half-lives than aspirin in blood and tissues.

Background: The oral and dental health and related quality of life of orphan children and adolescents-who are considered a vulnerable population-are critical for both individual and public health.
Objectives: This study aimed to investigate the status of the dental caries, oral hygiene, and dental treatment needs among a group of Turkish male orphan children and adolescents, as well as their impact on oral health-related quality of life.
Methods: A total of 112 orphan children and adolescents aged between 9 and 17 years living in a residential care facility in Istanbul, Türkiye, were involved in this cross-sectional study.

Cordyceps sinensis (C. sinensis) is a valuable edible fungus, known for its therapeutic benefits, including immune enhancement and anti-inflammatory effects, making it an important component in nutritional applications. However, its delicate nature makes long-term storage challenging, with conventional freezing often leading to the loss of bioactive compounds.
