Box Behnken Design for Optimization of Operating Conditions for Methyl Violet Decolorization using Momordica Charantia Peroxidase
Abstract: Methyl violet is a triphenylmethane dye which is recalcitrant and it is difficult to degrade it by conventional methods. Enzyme based remediation methods have gained importance as they are cost effective, highly specific and eco friendly. Methyl violet was degraded using crude peroxidase from bitter gourd (Momordica charantia). To optimize the decolorization conditions of methyl violet by crude Momordica charantia peroxidase, Response Surface Methodology (RSM) using Box Behnken (BB) design …

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 …

Demodex spp. (Acari: Demodicidae) Infestation in Humans: Diagnostic Clues and Therapeutic Approaches to Primary and Secondary Demodicosis.
Abstract: Demodicosis represents an inflammatory dermatosis and adnexal disorder arising from pathologic overgrowth of Demodex mites, primarily Demodex folliculorum and Demodex brevis, which are ubiquitous human ectoparasites residing in pilosebaceous units and eyelid margins. Once regarded as benign commensals, these mites are now recognized as primary drivers or key cofactors in diverse clinical phenotypes, including papulopustular eruptions, pityriasis folliculorum, rosacea-like disorders, blepharitis, meibomian gland dysfunction, and exacerbations of comorbid dermatoses such …

Solid Acid Catalysts for the Selective Conversion of Biomass to Levulinic Acid
Abstract: Levulinic acid (LA) has emerged as a versatile platform chemical with significant potential for producing renewable fuels like gamma-valerolactone (GVL), biodegradable polymers, and fine chemicals from biomass (both terrestrial and marine which ae rich in carbohydrate). The selective conversion of biomass-derived carbohydrates to LA requires efficient catalytic systems that can overcome the recalcitrance of the biomass, namely the stiff-necked structural integrity of cellulose and the kind of strong interactions between …

White-Rot Fungi-Based Bioprocessing for Circular Bioeconomy & Valorization of Lignocellulosic Waste
Abstract: The escalating global demand for sustainable resource management and the imperative to reduce dependence on fossil-based products have positioned the circular bioeconomy as a transformative paradigm for the 21st century. Lignocellulosic biomass, generated abundantly as agricultural and forestry residues, constitutes one of the most underexploited renewable carbon sources on Earth, yet its recalcitrant structure, interlinking cellulose, hemicellulose, and lignin, has long impeded its efficient valorization. White-rot fungi (WRF), predominantly belonging …

Nano Cellulose: A Bionano Material from Lignocellulosic Biomass
Abstract: In paper industry, nano technological advances are of great importance in targeting high quality, efficiency and market potential. Lignocellulosic biomass is a natural biopolymer with cellulose fibrils in a matrix of lignin and hemi cellulose. One of the most relevant nanomaterials of our paper industry is nano crystalline cellulose, a renewable, recyclable and abundant nano material obtained from lignocellulosic biomass. Currently the paper industry uses nanotechnology in two ways: to …

Prevalence and Correlates of Hardcore Smoking in India
Abstract: Hardcore smoking refers to inability or unwillingness of regular smokers to quit. Daily smoking, no past quit attempt and no future quit intention, nicotine dependence, etc., are used to define hardcore smoking. Continued use, nicotine dependence and recalcitrant to interventions makes hardcore smoker more prone to tobacco-induced diseases. However, despite multiple estimates of smoking prevalence in India, there is little information on hardcore smoking epidemiology, which has bearing on smoking …
