The microleakage of conventional GIC to that of resin modified GIC and bulk filled hybrid restorative system (GIC) to restore class I cavities in primary molars is of interest. Hence, a total of 60 extracted human primary molar teeth collected were divided into three main groups. Class I cavity was prepared in all teeth and restore with conventional GIC, resin modified GIC and bulk filled hybrid restorative system (GIC). Sections were viewed under stereomicroscope and the degree of microleakage was evaluated using specific scoring criteria. Among the three restorative materials, Glass hybrid Bulkfil restorative system GIC can be considered as the best material in the terms of microleakage.

Objective: Aim: To analyse the effectiveness of the National Health Service of Ukraine, which performs the functions of a purchaser of medical services and medicines under the Medical Guarantees Programme during wartime, as well as to identify and characterise the key challenges it faces and to propose effective solutions based on statistical data and comparative analysis concerning the provision of high-quality and effective medical care to the population, along with suggesting the development of promising directions for improving the performance of the National Health Service..
Patients And Methods: Materials and Methods: Retrospective, analytical, and modelling methods were used to assess the main processes related to the activities of the National Health Service of Ukraine as a key actor in the financing of medical services within the healthcare system under martial law conditions in Ukraine.

This study assessed the effect of saliva exposure on roughness (Ra) and Vickers hardness (VHN) of two direct restorative materials, enamel, and dentin adjacent to the restorations. Enamel and dentin cavities in molars (n = 10) were restored with a) bulk-fill resin composite (Tetric N-Flow Bulk Fill, BF) with the application of a universal adhesive (Tetric N-Bond Universal) and b) alkasite restorative material (Cention N, CN) with and without the application of a universal adhesive. After 24 h (baseline), surface roughness and hardness of the restorative material and dental tissues were assessed at 100 μm from the tooth/restoration interface.

This study examines how choral singing functions as a mechanism for sustaining ritual practice and reinforcing cultural identity. By integrating perspectives from musicology, social psychology, and cognitive science, it explores how collective vocal performance supports emotional attunement, group cohesion, and symbolic memory in culturally diverse contexts. A mixed-methods approach was applied, combining ethnographic observation, survey-based data, and cognitive measures with AI-informed frameworks such as voice emotion recognition and neural synchrony modeling.

Disorder and non-Hermitian effects together can upend how waves localize. In a 1D disordered chain, the non-Hermitian skin effect (NHSE) can induce Anderson delocalization, defying the usual rule that disorder in low dimensions always localizes states. While weak disorder leaves the NHSE intact, strong disorder restores Anderson localization.

Food intake is a key regulator of the digestive system function; however, little is known about organ- and sex-specific differences in food-driven regulation. We placed male and female C57Bl/6 mice on time-restricted feeding (TRF), limiting access to food to an 8-hour window. Food was added either at dark (ZT12) or light (ZT0) onset for 14 days.
