Article Synopsis
  • Photocatalysts are effective tools for breaking down harmful synthetic and organic materials, like dyes in wastewater, and this study focuses on reduced graphene oxide (rGO) as a promising option.
  • The research specifically evaluates rGO reduced at 250 °C (rGO-250), which shows superior efficiency in degrading dyes (indigo carmine and neutral red) due to its large surface area and strong adsorption characteristics.
  • Additionally, rGO-250 demonstrates enhanced carbon dioxide (CO) absorption compared to other forms of reduced graphene oxide, indicating its potential use in environmental applications.

Lactic acid bacteria (LAB) are excellent anaerobic fermenters that produce highly valuable grass-based animal feed containing essential nutrients. In the present study, an ensiling process was used to improve anaerobic fermentation in triticale silage under different moisture conditions with LAB. The triticale was treated with either a single bacterium or combined LAB and then vacuum-sealed.

In this study, the preparation of SmCuZrO double perovskites was carried out through the utilization of a sol-gel technique. The SmCuZrO displayed notable conductivity, impressive electrocatalytic activity, and rapid electron transfer. The monitoring of risperidone (RIS) in tablet samples is greatly influenced by these properties.

A novel mixed ligand Ni(II) metal complex has been investigated for the modification in structural conformation, coordination bond, and noncovalent interactions. The novel Ni(II) metal complex [Ni(TFPB)(1,10-Ph)(DMF)] has been synthesized and structurally characterized, which featured six coordination with three bidentate ligands connected through oxygen and nitrogen atoms. The single-crystal X-ray analysis showed that the compound possessed octahedral geometry and C-H…F, C-H…O, and π…π intermolecular interactions resulting in the formation of supramolecular architecture contributed significantly towards the crystal packing and molecular stability.

This study showed that bio-functional silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) were synthesized in aqueous extracts of Gymnema sylvestre leaves and tested for toxicity assessment against triple-negative breast cancer cells (TNBC). Biofunctional nanoparticle (NPs) samples were characterized using UV-Vis spectroscopy, FT-IR, XRD, SEM, and TEM. The results showed that the phytofabrication of AgNPs resulted in a dark brown, UV-vis maximum absorbance peak at 413 nm.

Infectious diseases caused by bacteria are at risk of spreading and prolonging due to antimicrobial resistance. It is, therefore, urgently necessary to develop a more effective antibiotic alternative strategy to control pathogen spread. In general, probiotics have been recommended as a substitute for antibiotics that inhibit pathogens.

The most prevalent chronic liver disorder in the world is fatty liver disease caused by a high-fat diet. We examined the effects of -KCC48 on high-fat diet-induced (HFD) fatty liver disease in mice. We used the transcriptome tool to perform a systematic evaluation of hepatic mRNA transcripts changes in high-fat diet (HFD)-fed animals and high-fat diet with (HFLPD)-fed animals.

The present study was targeted to treat the cheese factory processed wastewater by using natural coagulants. The results were compared with the CPCB wastewater discharge limit and most of the parameters were exceeded the standard limit. In the present investigation, the processed wastewater was subjected to treatment with Tamarindus indica L.

The health benefits of probiotics have been known for decades, but there has only been limited use of probiotics in the treatment of obesity. In this study, we describe, for the first time, the role of cell-free metabolites (CM) from -RO6 (CMRO6) in adipogenesis and lipogenesis in 3T3-L1 pre-adipocytes. The experimental results show that CMRO6 treatment effectively reduced lipid droplet accumulation and the expression of CCAAT/enhancer-binding protein α and β (C/EBPα and C/EBPβ), peroxisome proliferator-activated receptor γ (PPAR-γ), serum regulatory binding protein 1c (SREBP-1c), fatty acid-binding protein 4 (FABP4), fatty acid synthase (FAS), acetyl CoA carboxylase (ACC), phosphorylated p38MAPK, and Erk44/42.

Early and automatic detection of colorectal tumors is essential for cancer analysis, and the same is implemented using computer-aided diagnosis (CAD). A computerized tomography (CT) image of the colon is being used to identify colorectal carcinoma. Digital imaging and communication in medicine (DICOM) is a standard medical imaging format to process and analyze images digitally.

Antimicrobial resistance is an emerging condition that increases the risk of spreading and prolonging infectious diseases globally. Therefore, a new alternative strategy for antibiotics is required urgently to control pathogens spreading. Probiotics are considered as an alternative for antibiotics that inhibit pathogens.

Article Synopsis
  • - The study presents a new 2D GNR-CoB composite used for electrochemical sensing and degrading malachite green (MG), with strong analytical performance shown through various imaging and testing methods.
  • - The modified pencil graphite electrode with the composite achieved an impressive limit of detection (LOD) of 1.92 nM and demonstrated a high sensitivity, allowing effective detection of MG in real samples like green peas and lady's fingers.
  • - Additionally, the 2D GNR-CoB composite exhibited excellent photocatalytic degradation of MG, achieving a 91.28% efficiency by generating reactive radicals under visible light, with a proposed mechanism for this degradation process being discussed.
