Bioadhesive Chitosan Films Loading Curcumin for Safe and Effective Skin Cancer Topical Treatment.

: This study aimed to evaluate the safety and efficacy of chitosan-based bioadhesive films for facilitating the topical delivery of curcumin in skin cancer treatment, addressing the pharmacokinetic limitations associated with oral administration. : The films, which incorporated curcumin, were formulated using varying proportions of chitosan, polyvinyl alcohol, Poloxamer 407, and propylene glycol. These films were assessed for stability, drug release, in vitro skin permeation, cell viability (with and without radiotherapy), and skin irritation.

The Role of Nutrition Across Production Stages to Improve Sow Longevity.

Modern hyperprolific sows are increasingly susceptible to health challenges. Their rapid growth rates predispose them to locomotor disorders, while high metabolic demands, reduced backfat thickness, and increased protein accretion heighten their vulnerability to heat stress and dystocia. Additionally, prolonged farrowing negatively affects the oxidative and inflammatory status of these females.

Revealing catalyst restructuring and composition during nitrate electroreduction through correlated operando microscopy and spectroscopy.

Electrocatalysts alter their structure and composition during reaction, which can in turn create new active/selective phases. Identifying these changes is crucial for determining how morphology controls catalytic properties but the mechanisms by which operating conditions shape the catalyst's working state are not yet fully understood. In this study, we show using correlated operando microscopy and spectroscopy that as well-defined CuO cubes evolve under electrochemical nitrate reduction reaction conditions, distinct catalyst motifs are formed depending on the applied potential and the chemical environment.

Combined technique versus stent-retriever alone: Interaction analysis of angioarchitectural and technical features.

Introduction: We aimed to explore if anatomical and technical features could interact and favor the chances of reperfusion according to the treatment strategy: combined technique (CoT) of mechanical thrombectomy (MT) with contact aspiration and stent-retriever (SR) versus SR alone.

Methods: Retrospective analysis of a prospective MT database for carotid terminus or MCA-M1 occlusion, first-line SR alone or CoT, and angiographic run with SR deployed on the first pass. The primary analysis involved the interaction between clinical and angiographic characteristics and first-line MT modality on first-pass effect (FPE; first pass eTICI2c-3).

Effects of ionizing radiation on osteoblastic cells: In vitro insights into the etiopathogenesis of osteoradionecrosis.

Objective: This in vitro study aimed to analyze the effects of ionizing radiation on immortalized human osteoblast-like cells (SaOS-2) and further assess their cellular response in co-culture with fibroblasts. These analyses, conducted in both monoculture and co-culture, are based on two theoretical models of osteoradionecrosis - the theory of hypoxia and cellular necrosis and the theory of the radiation-induced fibroatrophic process.

Design: SaOS-2 cells were exposed to ionizing radiation and evaluated for cell viability, nitric oxide (NO) production, cellular morphology, wound healing, and gene expression related to the PI3K-AKT-mTOR pathway.
