This study emphasized on the synthesis of zinc oxide nanoparticles (ZnO NPs) in an environmentally friendly manner from the extract of Catharanthus roseus leaves and its antibacterial assessment against the pneumonia-causing pathogen Klebsiella pneumoniae. This simple and convenient phytosynthesis approach is found to be beneficial over conventional methods, wherein plants serve as excellent reducing, capping, and stabilizing agents that enables the formation of ZnO NPs without the use of harmful chemicals. The formation of ZnO NPs was confirmed through several characterization techniques such as UV-visible spectroscopy, XRD, FT-IR, SEM, HR-TEM, and EDX.

Cerium oxide nanoparticles (CeONPs) have a broad scale of applications in the biomedical field due to their excellent physicochemical and catalytic properties. The present study aims to synthesize the CeONPs from () leaf extract, which has been used in Indian traditional medicine for its neuroprotective properties. The CeONPs were characterized by ultraviolet-visible, X-ray diffraction, Fourier transform infrared, Raman spectroscopy, scanning electron microscopy- energy dispersive X-ray spectroscopy, and high-resolution transmission electron microscopy.

Purpose: 4-Hydroxyisophthalic acid (4-HIA) is a bioactive compound present in the roots of , which has attracted considerable attention in attenuating oxidative stress-related neurodegenerative diseases. However, its efficacy is limited because of its low solubility and bioavailability. Therefore, the present study aimed to encapsulate 4-HIA using biocompatible copolymer polylactide-co-glycolide (PLGA) and evaluate its antioxidant and neuroprotective potential.

Hepatocellular carcinoma (HCC) stands third among cancer-related deaths globally. Owing to its high incidence and linked mortality, early diagnosis is alarming for patient survival and the management of patients with developing HCC requires immediate attention. Advances in the knowledge of cancer biology and recognizing unique molecular candidates, including genomic and proteomic profiles, substantiate our understanding about several biological signatures connected with HCC.

Objective: The present study was aimed to investigate the neuroprotective effects of (Dh) aqueous root extract and its compounds against age-related oxidative stress (OS) in the discrete regions of the rat brain.

Materials And Methods: Male Wistar albino rats of 4- and 22-month-old were divided into control and six supplemented groups. The supplemented groups were orally administered with ellagic acid (EA), 4-hydroxyisophthalic acid (4-HIA), and Dh extract for 30 days.

The synergistic effects of physical exercise and diet have profound benefits on brain function. The present study was aimed to determine the effects of exercise and Decalepis hamiltonii (Dh) on age-related responses on the antioxidant status in discrete regions of rat brain. Male Wistar albino rats of 4 and 18 months old were orally supplemented with Dh extract and swim trained at 3 % intensity for 30 min/day, 5 days/week, for a period of 30 days.

Exercise has beneficial effects on brain function, including the promotion of plasticity and the enhancement of learning and memory performance. To further explore the molecular changes in the protein expression levels in the cerebral cortex of physically trained rats, male Wistar rats 8 months old were selected and subjected to swimming training in a rectangular glass tank for 30 min/day, 6 days/week and 3% of load for 4 weeks. Two dimensional gel electrophoresis followed by mass spectrometrical identification assigning spots to proteins and determination of coomassie-densities of the protein spots were carried out.
