Gut Microbial Metabolites in Inflammatory, Metabolic, and Neurologic Disorders.
Abstract: The human gut microbiota transforms dietary and hostderived substrates into a diverse array of metabolites—including shortchain fatty acids (SCFAs), hydrogen sulfide (H₂S), bile acid derivatives, indoles, trimethylamine Noxide (TMAO), branchedchain amino acid (BCAA) derivatives, and lipopolysaccharide (LPS)—that act as key signaling mediators along epithelial, immune, endocrine, and neural axes. These metabolites regulate barrier integrity, energy homeostasis, inflammation, and gut–brain communication and are increasingly implicated in the pathogenesis of inflammatory bowel …

Productivity of Hydraulically Fractured Calcite Rich Shale Reservoirs Enhanced by Acid
Abstract: The current low oil prices have highlighted the need for enhancement to current production from shale formations. Prolonging the production life and increasing productivity of the fracture network in the shale plays can be a way to improve the economics. Many shale wells, drilled and completed based on current completion strategies, show sharp decline after initial flash production. One of the reasons behind this can be attributed to closure of …

Internal Resorption in the Dentin-Pulpal Complex: An Etiological Link to the Metabolic Acidosis of Diabetes
Abstract: The etiology of internal resorption is not by bacteria or caries but most likely initiated from chronic pulpal inflammation (i.e., chronic pulpitis) following intrusive injury to the dental pulp by one or more of the following means: (1) Traumatic injury (i.e., the most likely etiology) which often involves the oral cavity and teeth. (2) Chemical injury may be by elevated dose fluoride use or from caustic products used in bleaching. …

Structural Modification of Sugarcane Bagasse using Alkaline, Acid, and Bleaching Pretreatments for Enhanced Yield of Poly (1→4)-β-D-glucopyranose (Cellulose) and Hemicellulose for Utilization as Biocomposites
Abstract: Sugarcane bagasse, a lignocellulosic byproduct generated in substantial quantities by the sugar industry, represents a promising feedstock for the sustainable production of enzymes and bio-based chemicals. Its high (1→4)-β-D-glucopyranose (cellulose) content, abundant availability, and low cost make it an ideal candidate for bioconversion processes. However, the inherent recalcitrance of bagasse, primarily due to its lignin-rich matrix, necessitates effective pretreatment strategies to enhance enzymatic digestibility. This study presents a comparative investigation …

An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …
