Environmental and Economic Assessment of Wind Turbine Blade Recycling Approaches.

Wind energy offers a low emission source of energy while also being among the cheapest forms of electricity generation in the United States. While most materials in a wind turbine can be recycled at the end of their life, large composite blades are often treated as waste, leading to potential strains on regional landfills, a loss of durable materials, and forfeiture of embodied energy. Numerous approaches exist for recycling composite wind blades at various levels of technological and commercial maturity.

Portomesenteric Venous Thrombosis Presenting as Bowel Gangrene.

Portal vein thrombosis (PVT) typically arises in patients with underlying cirrhosis, hepatobiliary malignancies, abdominal inflammatory conditions, or hematologic disorders. However, in non-cirrhotic individuals, PVT is less common and may initially present with minimal symptoms, escalating significantly if it extends to the mesenteric veins. Here, we present the case of a 37-year-old male with combined portal and mesenteric venous thrombosis, manifesting as acute intestinal obstruction.

Marine natural products as a source of novel anticancer drugs: an updated review (2019-2023).

Marine natural products have long been recognized as a vast and diverse source of bioactive compounds with potential therapeutic applications, particularly in oncology. This review provides an updated overview of the significant advances made in the discovery and development of marine-derived anticancer drugs between 2019 and 2023. With a focus on recent research findings, the review explores the rich biodiversity of marine organisms, including sponges, corals, algae, and microorganisms, which have yielded numerous compounds exhibiting promising anticancer properties.

Development of a Tandem Mass Spectral Library for the Detection of Triterpenoids in Plant Metabolome Based on Reference Standards.

Plant triterpenoids represent a diverse group of secondary metabolites and are thought to be valuable for therapeutic applications. For drug development, lead optimization, better knowledge of biological pathways, and high-throughput detection of secondary metabolites in plant extracts are crucial. This paper describes a qualitative method for the rapid and accurate identification of various triterpenoids in plant extracts using the LC-HR-ESI-MS/MS tool in combination with the data-dependent acquisition (DD) approach.

Caries Impacts and Experiences and Dental Care Utilization for Saudi Schoolchildren: Caries Impacts and Experiences Questionnaire for Children - A Disease-Specific Measure.

Introduction: The Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) is a disease-specific questionnaire that assesses the impact of caries on the oral health-related quality of life of children. This study aimed to establish a baseline for caries-specific impact on schoolchildren in Saudi Arabia and to examine its association with dental care utilization.

Methods: This cross-sectional study used random stratified cluster sampling among 4th-6th graders in Jeddah.
