A Comparative DFT Investigation of the Adsorption of Temozolomide Anticancer Drug over Beryllium Oxide and Boron Nitride Nanocarriers.

Herein, attempts were made to explore the adsorption prospective of beryllium oxide (BeO) and boron nitride (BN) nanocarriers toward the temozolomide (TMZ) anticancer drug. A systematic investigation of the TMZ adsorption over nanocarriers was performed by using quantum chemical density functional theory (DFT). The favorability of BeO and BN nanocarriers toward loading TMZ was investigated through A↔D configurations.

Interrogating the estrogen-mediated regulation of adrenocortical Klotho expression using ovariectomized albino rat model exposed to repeated restraint stress.

Reproductive aging is associated with altered stress response and many other menopausal symptoms. Little is known about the adrenal expression of the anti-aging protein Klotho or how it is modulated by estrogen in ovariectomized stressed rats. Fifty-six Wistar female rats were assigned into seven equal groups.

Ectomycorrhiza and ethylenediurea reduced the impact of high nitrogen and ozone stresses and increased the growth of .

is the central conifer plant affected by ozone and nitrogen pollutants among forest species worldwide. The growth of depends upon the ectomycorrhizal (ECM) association, which is usually disturbed by these factors. This study aims to understand how these factors affect plants at physiological and biochemical levels.

Genome-wide identification of NAC transcription factors and regulation of monoterpenoid indole alkaloid biosynthesis in .

NAC transcription factors (TFs) are crucial to growth and defense responses in plants. Though NACs have been characterized for their role in several plants, comprehensive information regarding their role in , a perennial ornamental plant, is lacking. Homology modelling was employed to identify and characterize NACs in .

Unveiling the Potential of BO Nanoflake as Effective Transporter for the Antiviral Drug Favipiravir: Density Functional Theory Analysis.

In this study, for the first time, boron oxide nanoflake is analyzed as drug carrier for favipiravir using computational studies. The thermodynamic stability of the boron oxide and favipiravir justifies the strong interaction between both species. Four orientations are investigated for the interaction between the favipiravir and the BO nanoflake.

ACE2/ACE imbalance mediates bisphenol A-induced lung injury in Wistar rats: Results from captopril versus losartan histo-biochemical study.

Bisphenol-A (BPA) is a synthetic chemical compound broadly used in the plastic and epoxy resin industries with a considerable potential for food contamination. Literary reports have suggested that the altered renin-angiotensin system (RAS) is a mechanism for lung injury and inflammation caused by variable agents. The current study sought to investigate the contribution of RAS to BPA-induced lung damage.

Frequency-dependent nonlinear optical response and refractive index investigation of lactone-derived thermochromic compounds.

Nonlinear optical (NLO) switchable materials play a crucial role in the fields of electronics and optoelectronics. The selection of an appropriate switching approach is vital in designing such materials to enhance their NLO response. Among various approaches, thermos-switching materials have shown a 4-fold increase in NLO response compared to other photo-switching materials.

Target and non-target effects of and combined extract on mosquitoes.

The present study focused on extracting green larvicides from extracts of the combination of  and  using different solvents of increasing polarity in a Soxhlet extractor and evaluating their ovicidal, larvicidal, and cytotoxic activities. The most promising among all tested extracts was hexane extract. The ovicidal activity of the hexane PH2 extract resulted in a significant (p < 0.

Ameliorative effect of zinc oxide nanoparticles against potassium bromate-mediated toxicity in Swiss albino rats.

Potassium bromate (PB) is a commonly used food additive, a prominent water disinfection by-product, and a class IIB carcinogen. It exerts a various degree of toxicity depending on its dose and exposure duration consumed with food and water in the living organisms. The present investigation aims to demonstrate the protective efficacy of zinc oxide nanoparticles (ZnO NPs) derived from Ochradenus arabicus (OA) leaf extract by green technology in PB-challenged Swiss albino rats.

Histopathology of the Liver, Kidney, and Spleen of Mice Exposed to Gold Nanoparticles.

Gold nanoparticles (GNPs) are biocompatible nanomaterials that are currently researched for biomedical applications such as imaging and targeted drug delivery. In this investigation, we studied the effects of a single dose (injected on day 1) as well as a priming dose (two injections with a gap of one week) of 5 nm, 20 nm, and 50 nm diameter GNPs on the structural and biochemical changes in the liver, kidney, and spleen of mice. The results showed that small sized GNPs (5 nm) produced significant pathological changes in the liver on day 2 that gradually reduced on day 8.

A priming dose protects against gold nanoparticles-induced proinflammatory cytokines mRNA expression in mice.

Aim: To study the effect of priming doses of gold nanoparticles (GNPs) on proinflammatory cytokines in different organs of mice.

Materials & Methods: Mice were injected with a single or two doses (priming group) of GNPs (5, 20 and 50 nm) and sacrificed after 1 or 7 days. The mRNA expressions of IL-1β, IL-6 and TNF-α were determined in liver, kidney and spleen.
