A chromium and tannic acid resistance fungal strain was isolated from tannery effluent, and identified as Aspergillus niveus MCC 1318 based on its rDNA gene sequence. The MIC (minimum inhibitory concentration) of the isolate against chromium and tannic acid was found to be 200 ppm and 5% respectively. Optimization of physiochemical parameters for biosorption of chromium and tannic acid degradation was carried out by Plackett-Burman design followed by response surface methodology (RSM). The maximum chromium removal and tannic acid degradation was found to be 92 and 68% respectively by A. niveus. Chromium removal and tannic acid degradation was increased up to 11 and 6% respectively after optimization. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) was used to investigate biosorption phenomena.

Infected alveolar bone defects pose challenging clinical issues due to disrupted intrinsic healing mechanisms. Thus, the employment of advanced biomaterials enabling the modulation of several aspects of bone regeneration is necessary. This study investigated the effect of multi-functional nanoparticles on anti-inflammatory/osteoconductive characteristics and bone repair in the context of inflamed bone abnormalities.

Introduction: The mechanism of tannic acid (TA) intervention on methicillin-resistant (MRSA, USA 300) biofilm formation was explored using proteomics.

Methods: The minimum inhibitory concentration (MIC) of TA against the MRSA standard strain USA 300 was determined by two-fold serial dilution of the microbroth. The effects of TA were studied using crystal violet staining.

A multifunctional mitochondria-protective gene delivery platform promote intervertebral disc regeneration.

National Engineering Research Center for Biomaterials, Sichuan University, Chengdu, Sichuan, China. Electronic address:

Intervertebral disc degeneration (IDD) is a deleterious condition driven by localized inflammation and the associated disruption of the normal homeostatic balance between anabolism and catabolism, contributing to progressive functional abnormalities within the nucleus pulposus (NP). Despite our prior evidence demonstrating that a miR-21 inhibitor can have regenerative effects that counteract the progression of IDD, its application for IDD treatment remains limited by the inadequacy of current local delivery systems. Here, an injectable tannic acid (TA)-loaded hydrogel gene delivery system was developed and used for the encapsulation of a multifunctional mitochondria-protecting gene nanocarrier (PHs).

Sustainable fabrication of Fe2O3/C nanoparticles via acacia nilotica extract for enhanced supercapacitor performance.

Nanotechnology

December 2024

Department of Chemistry, King Faisal University, Department of Chemistry, College of Science, King Faisal University, P.O. Box 400, Hofuf, Al-Ahsa 31982, Saudi Arabia, Kinga Faisal University, Al-Hasa, Al-Hasa, 31982, SAUDI ARABIA.

This research investigates the eco-friendly production of iron oxide nanoparticles and their combination with carbon to create the FeC-1and FeC-2 NPs, using seedless pods of Acacia nilotica. These pods, rich in tannins and flavonoids, serve as a natural reducing, stabilizing, and carbon source. The study details the synthesis of FeC NPs through a non-toxic, green method and examines the influence of varying concentrations of Acacia nilotica extract (ANE) on the electrochemical characteristics of the resulting n FeC-1and FeC-2 electrodes.
