Green Synthesis, Characterization and Bioactivity of Seed-Wrapped Zinc Oxide Nanoparticles.

In the realm of nanoparticles, metal-based nanoparticles have traditionally been regarded as the pioneering category. Compared to other nanoparticles, zinc oxide nanoparticles have several advantages, including optical and biological properties, which provide them a significant competitive advantage in clinical and biological applications. In the current investigation, we used an aqueous seed extract to synthesize nanoparticles of zinc oxide (ZnO NPs).

Role of Nanoparticles in Environmental Remediation: An Insight into Heavy Metal Pollution from Dentistry.

Environmental damage is without a doubt one of the most serious issues confronting society today. As dental professionals, we must recognize that some of the procedures and techniques we have been using may pose environmental risks. The usage and discharge of heavy metals from dental set-ups pollute the environment and pose a serious threat to the ecosystem.

Dynamic action of carotenoids in cardioprotection and maintenance of cardiac health.

Oxidative stress has been considered universally and undeniably implicated in the pathogenesis of all major diseases, including those of the cardiovascular system. Oxidative stress activate transcriptional messengers, such as nuclear factor-κB, tangibly contributing to endothelial dysfunction, the initiation and progression of atherosclerosis, irreversible damage after ischemic reperfusion, and even arrhythmia, such as atrial fibrillation. Evidence is rapidly accumulating to support the role of reactive oxygen species (ROS) and reactive nitrogen species (RNS) as intracellular signaling molecules.

Health benefits of wine and alcohol from neuroprotection to heart health.

Controversy is common during efforts to define the role of nutrition in health, but few modern reflections of such controversy are as vivid as the debate over wine. There exists no query that chronic alcohol abuse, a leading worldwide problem, causes neuronal dysfunction and brain damage. However, various epidemiologic studies in recent years have indicated that in comparisons with abstainers or never drinkers, light/moderate alcohol/wine consumers have lower risks of age-dependent cognitive decline and/or dementia, including Alzheimer's disease (AD) Neurodegenerative diseases such as AD and Parkinson's (PD) diseases are defined by a progressive neuronal dysfunction and an ensuing behavioral dysfunction.

Cytotoxic copper (II) mixed ligand complexes: crystal structure and DNA cleavage activity.

Two new mixed ligand complexes of copper (II) containing an imidazolyl terpyridine ligand, [Cu(Itpy)(bpy)](ClO(4))(2)·(H(2)O), 1, and [Cu(Itpy)(phen) (ClO(4))](ClO(4))·(H(2)O), 2 have been synthesized and characterized. Complex 1 has been found to possess a distorted square pyramidal geometry whereas 2 exhibit a distorted octahedral geometry. Electronic spectral titrations suggest that 1 and 2 bind to DNA intercalatively with the binding constant, K(b) (4.
