Fabrication of poly (lactic-co-glycolic acid)/gelatin electro spun nanofiber patch containing CaCO/SiO nanocomposite and quercetin for accelerated diabetic wound healing.

An open wound or sore on the bottom of the foot caused by diabetes is known as a diabetic foot ulcer. Preventive measures are essential, including consistent foot care and glycemic management. The dangers associated with diabetic foot ulcers can be reduced via early identification and timely treatment.

Enhanced wound healing by PVA/Chitosan/Curcumin patches: In vitro and in vivo study.

Biocompatible polymers are being used in recent times for treating skin injuries and burn wounds. Polymers like Poly Vinyl Alcohol and Chitosan are proven to be biocompatible with least toxic to treat injuries with minimal side-effects. Curcumin, a primary component of turmeric has anti-inflammatory properties and anti-microbial activity but has extremely low bioavailability.

In vitro evaluation of biodegradable nHAP-Chitosan-Gelatin-based scaffold for tissue engineering application.

The present study focuses on fabrication and characterisation of porous composite scaffold containing hydroxyapatite (HAP), chitosan, and gelatin with an average pore size of 250-1010 nm for improving wound repair and regeneration by Electrospinning method. From the results of -Ray Diffraction (XRD) study, the peaks correspond to crystallographic structure of HAP powder. The presence of functional group bonds of HAP powder, Chitosan and scaffold was studied using Fourier Transform Infrared Spectroscopy (FTIR).

Association of SNP rs7181866 in the nuclear respiratory factor-2 beta subunit encoding GABPB1 gene with obesity and type-2 diabetes mellitus in South Indian population.

GABPB1, known as nuclear respiratory factor 2 (Nrf2), activates mitochondrial genes that are responsible for oxidative phosphorylation. Earlier studies on GABPB1 reported that two single nucleotide polymorphisms (SNPs) such as rs7181866 and rs8031031, to be associated with increased endurance in athletes. In the present study, a cohort of 302 South Indians, including normoglycemic healthy controls, T2DM with and without obesity were genotyped for the two SNPs by PCR-RFLP method and correlated with serum adipokines.

Phytosynthesized gold nanoparticles from C. roxburghii DC. leaf and their toxic effects on normal and cancer cell lines.

Gold nanoparticles are considered of great importance compared to other noble metal nanoparticles and its wide range of applications like pharmaceutics, therapeutics and diagnostics etc. During the past decade, phytosynthesized gold nanoparticles (AuNPs) are more focused in in vitro and in vivo study. The present study was focused on the gold chloride and phytosynthesized gold nanoparticles from aqueous leaf extract of Cassia roxburghii and their toxic effects on African green monkey normal kidney Vero cell line and three different cancer cell lines such as HepG2, MCF7 and HeLa.

Phytogenic synthesis of silver nanoparticles, optimization and evaluation of in vitro antifungal activity against human and plant pathogens.

An attempt was made to synthesis of biocompatible silver nanoparticles from ten different Cassia spp. Among them, Cassia roxburghii aqueous leaf extract supported the synthesis of highly efficient and stable AgNPs. The synthesis of AgNPs was optimized at different physico-chemical condition and highly stable AgNPs were synthesized with 1.

Synthesis of Leucas Aspera Extract Loaded Gold-PLA-PEG-PLA Amphiphilic Copolymer Nanoconjugates: In Vitro Cytotoxicity and Anti-Inflammatory Activity Studies.

Gold nanoparticles (GNPs) are synthesized using the medicinal plant Leucas Aspera extract (LAE) and poly lactic acid-co-poly ethylene glycol-co-poly lactic acid (PLA-PEG-PLA) copolymer by water-in-oil (W/O) emulsion method. The proposed method of W/O emulsion technique involves synthesis of GNPs and loading of Leucas Aspera extract on to the PLA-PEG-PLA copolymer matrix simultaneously. The synthesized GNPs are characterized by Fourier transform infra-red (FTIR) spectroscopy, dynamic light scattering (DLS), X-ray diffractometry (XRD) and transmission electron microscopy (TEM).

Mycosynthesis of silver and gold nanoparticles: Optimization, characterization and antimicrobial activity against human pathogens.

This study was aimed to isolate soil fungi from Kolli and Yercaud Hills, South India with the ultimate objective of producing antimicrobial nanoparticles. Among 65 fungi tested, the isolate, Bios PTK 6 extracellularly synthesized both silver and gold nanoparticles with good monodispersity. Under optimized reaction conditions, the strain Bios PTK 6 identified as Aspergillus terreus has produced extremely stable nanoparticles within 12h.

Biosynthesis characterization of silver nanoparticles using Cassia roxburghii DC. aqueous extract, and coated on cotton cloth for effective antibacterial activity.

The present study reports the green synthesis of silver nanoparticles (AgNPs) from silver precursor using a plant biomaterial, Cassia roxburghii DC., aqueous extract. The AgNPs were synthesized from the shade-dried leaf extract and assessed for their stability; they elucidated characteristics under UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, high-resolution transmission electron microscopy, and energy dispersive X-ray spectroscopy.

Pathophysiological insights of methylglyoxal induced type-2 diabetes.

Diabetes mellitus is a metabolic disorder constituting a major health problem whose prevalence has gradually increased worldwide over the past few decades. Type 2 diabetes mellitus (T2DM) remains more complex and heterogeneous and arises as a combination of insulin resistance and inadequate functional β-cell mass and comprises about 90% of all diabetic cases. Appropriate experimental animal models are essential for understanding the molecular basis, pathogenesis of complications, and the utility of therapeutic agents to abrogate this multifaceted disorder.

Production of cellulase enzyme by Trichoderma reesei Cefl9 and its application in the production of bio-ethanol.

The present study aimed at the production of cellulase enzyme from the cellulolytic fungi Trichoderma reesei CEF19 and subsequent application of the cellulase for the fermentation of ethanol. For the same, the cellulolytic fungi, Trichoderma reesei CEF19 was isolated and was allowed to produce cellulase enzyme using optimized conditions. The cellulase enzyme was extracted and purified with the help of ammonium sulphate precipitation, dialysis followed by ion exchange chromatography with DEAE-Sephadex column.
