Low-Speed Platelet-Rich Fibrin Membrane in Conjunction With Demineralized Freeze-Dried Bone Allograft (DFDBA) Compared to Collagen Membrane With DFDBA in Noncontained Intraosseous Defects of Stage III Periodontitis: A Randomized Controlled Clinical Trial.

Noncontained (1- or combined 1- to 2-wall) periodontal intraosseous defects represent challenging clinical situations with unpredictable surgical therapeutic outcomes. This randomized clinical trial assessed demineralized freeze-dried bone allograft (DFDBA) with low speed-platelet-rich fibrin (PRF) membrane compared to DFDBA with collagen membrane (CM) in the surgical periodontal therapy of noncontained intraosseous defects of stage III periodontitis patients. Twenty-two stage III periodontitis patients with noncontained intraosseous defects measuring ≥3 mm and clinical attachment loss ≥5 mm were randomly allocated into two groups: test group (low-speed PRF membrane + DFDBA) and control group (CM + DFDBA), with 11 participants per group.

Recent trends in transforming different waste materials into graphene via Flash Joule Heating.

The conversion of waste materials into graphene using the Flash Joule Heating (FJH) method presents an eco-friendly and sustainable approach to addressing the global issue of environmental pollution. FJH efficiently transforms carbon-based materials, such as plastics, batteries, and food wastes, into high-quality graphene by applying a high-voltage electrical current that generates temperatures exceeding 3000 °C within milliseconds to seconds. This technique not only offers a rapid and energy-efficient pathway for graphene synthesis but also tackles the environmental drawbacks of traditional waste disposal methods.

Adaptive hybrid virtual inertia controller for PMSG-based wind turbine based on fuzzy logic control.

The integration of renewable energy sources into microgrids presents some challenges due to the decreased system overall inertia associated with the presence of converter -based sources. To overcome this issue and to enhance the system inertia, various concepts for virtual inertial control have been proposed in the literature. However, the concept of improving the system frequency through wind turbines has gained widespread acceptance.

Structural and Functional Characterization of the Aorta in Hypertrophic Obstructive Cardiomyopathy.

Background: Changes in the phenotype and genotype in hypertrophic cardiomyopathy (HCM) are thought to involve the myocardium as well as extracardiac tissues. Here, we describe the structural and functional changes in the ascending aorta of obstructive patients with HCM.

Methods: Changes in the aortic wall were studied in a cohort of 101 consecutive patients with HCM undergoing myectomy and 9 normal controls.

Prevalence and pattern of skin disorders among children living in orphanages in Fayoum and Giza governorates, Egypt.

Background: Childhood is a crucial period that shapes a person's growth and development. For orphans, a lack of familial support affects their upbringing, making orphanages crucial for care. Children living in orphanage centers are vulnerable to several conditions, including dermatological disorders, due to factors such as malnutrition, overcrowding, and poor hygiene.
