Anti-Bacterial and Anti-Dermatophytic Activity of Extracellular Secondary Metabolites of Streptomyces glaucescens NTSB-37 Isolated from Lichen Parmotrema perlatum (Huds.) M. Choisy in Kolli Hills, Tamil Nadu, India.

Lichen-associated endophytic Actinobacteria, particularly Streptomyces species, are recognized for their production of bioactive secondary metabolites with significant pharmaceutical potential. With the escalating prevalence of diseases, Streptomyces species are being investigated for its natural source of antimicrobial compounds for new antibiotics. This study focuses on the bioactive properties of secondary metabolites from lichen-associated endophytic Actinobacteria, focusing on Streptomyces glaucescens NTSB-37 isolated form lichen, Parmotrema perlatum (Huds.

Algae-mediated copper nanocatalyst for aerobic oxidation and dye decolourization via sustainable wastewater treatment.

In recent years, several physicochemical methods have been proposed for decolourising textile dyes; however, few have been adopted by the textile industry because of factors such as high cost, low efficiency, and limited applicability to a wide range of dyes. The current study focuses on synthesising algae-mediated Cu and CuO nanocatalysts (Alg-Cu and Alg-CuO) using natural waste materials from green algae. The synthesised Alg-CuO nanocatalyst was characterised and confirmed using SEM, TEM, UV, FT-IR, XRD, XPS, GC-MS, and TGA.

Synthesis, antimicrobial, antioxidant, tyrosinase inhibitory activities, and computational studies of novel chromen[2,3-c]pyrazole derivatives.

In this study, one-pot multicomponent reactions of novel chromeno[2,3-c]pyrazole derivatives (1-14) were performed using an AlCl catalyst via cyclisation. Various spectral and chromatographic techniques were used to elucidate the structure of the synthesised derivatives (1-14). The synthesised compounds were then inspected for their antibacterial, antioxidant, and tyrosinase inhibition activities.

The Influence of Glycemic Control Over Post-extraction Healing in Diabetic Patients.

Background Diabetes mellitus hinders wound healing after tooth extractions due to hyperglycemia, causing complications like infections and delayed recovery. The precise role of glycemic control in healing remains uncertain. This study aims to clarify it by comparing outcomes in patients with well-controlled and poorly controlled blood sugar levels.
