Ginger (Zingiber officinale) has enormous medicinal properties and health benefits.

In Vitro Cytotoxicity and Interaction of Noscapine with Human Serum Albumin: Effect on Structure and Esterase Activity of HSA.

Noscapine is effective to inhibit cellular proliferation and induced apoptosis in nonsmall cell, lung, breast, lymphoma, and prostate cancer. It also shows good efficiency to skin cancer cells. In the current work, we studied the mechanism of interaction between the anticancer drug noscapine (NOS) and carrier protein human serum albumin (HSA) by using a variety of spectroscopic techniques (fluorescence spectroscopy, time-resolved fluorescence, UV-visible, fluorescence resonance energy transfer (FRET), Fourier transform infrared (FTIR), and circular dichroism (CD) spectroscopy), electrochemistry (cyclic voltammetry), and computational methods (molecular docking and molecular dynamic simulation).

The structural, morphological, and mechanical properties of resultant nanocomposite hydrogel films were further investigated to analyze the effects of polyol and NaMMT on the characteristic properties.

Physicochemical Characterization of Curcumin Loaded Chitosan Nanoparticles: Implications in Cervical Cancer.

Background: Curcumin is a potent anticancer agent and has great potential efficacy against different types of cancers. A major disadvantage of curcumin, however, is its poor solubility and bioavailability.

Objective: The aim of the present work is to synthesize chitosan and curcumin-loaded chitosan nanoparticles and their characterization through various physicochemical methods and cellular uptake in cervical cancer cell line SiHa.

Biocompatible and mechanically robust nanocomposite hydrogels for potential applications in tissue engineering.

The synergistic contributions of nanofillers and polymer matrix induce remarkable properties in nanocomposite hydrogels. Present article reports the facile synthesis of biocompatible nanocomposite hydrogels using microporous multi wall carbon nanotubes (MWCNTs) dispersed chitosan (CH)-Acrylonitrile (AN), N,N'-methylenebisacrylamide (MBAAm) and linseed polyol through solution blending method. Polyol and N,N'-methylenebisacrylamide (MBAAm) was used as the crosslinking agent.

Peroxynitrite-modified histone as a pathophysiological biomarker in autoimmune diseases.

Under physiological conditions, reactive nitrogen and oxygen species are produced continuously. However, excess of these radicals may damage biomolecules like lipids, proteins and nucleic acids. These reactive species have been implicated in many disease conditions including acute/chronic inflammation, rheumatoid arthritis (RA), neurodegenerative diseases and systemic lupus erythematosus (SLE).

Characterization and carboplatin loaded chitosan nanoparticles for the chemotherapy against breast cancer in vitro studies.

Aim of the studies to synthesized chitosan nanoparticles by an ionic interaction procedure. The nanoparticles were characterized by physicochemical methods like, DLS, TEM, Surface potential measurements, FT-IR and DSC. The average particle size of chitosan and carboplatin nanoparticles was found to be 277.

Characterization and anti-proliferative activity of curcumin loaded chitosan nanoparticles in cervical cancer.

In the present study the chitosan nanoparticles (CsNPs) and curcumin loaded chitosan nanoparticles (CLCsNPs) were synthesized by tripolyphosphate (TPP) cross-linking method. The nanoparticles were prepared within a zone of appropriate chitosan and TPP concentrations. The average size of CsNPs and CLCsNPs were approximately 189±11.

Relief of Oxidative Stress Using Curcumin and Glutathione Functionalized ZnO Nanoparticles in HEK-293 Cell Line.

To elucidate the effect of zinc oxide nanoparticles (ZnO-NPs) with different surface modifications in relieving the oxidative stress in cultured human embryonic kidney cells (HEK-293) following investigation was performed. Oxidative stress was artificially induced by hydrogen peroxide in HEK-293 cell culture and its management was studied. Alkyl amines modified ZnO-NPs with curcumin and reduced glutathione (GSH) functionalization was used in managing oxidative stress and had shown promising results.

Ethyl acetate Salix alba leaves extract-loaded chitosan-based hydrogel film for wound dressing applications.

High toxicity and multidrug resistance associated with various standard antimicrobial drugs have necessitated search for safer alternatives in plant-derived materials. In this study, we performed biological examination of chitosan-based hydrogel film loaded with ethyl acetate Salix alba leaves extract against 11 standard laboratory strains. FTIR showed regeneration of saccharide peak in CP1A at 1047 cm(-1) and increased in height of other peaks.

Redox cycling of endogenous copper by ferulic acid leads to cellular DNA breakage and consequent cell death: A putative cancer chemotherapy mechanism.

Ferulic acid (FA) is a plant polyphenol showing diverse therapeutic effects against cancer, diabetes, cardiovascular and neurodegenerative diseases. FA is a known antioxidant at lower concentrations, however at higher concentrations or in the presence of metal ions such as copper, it may act as a pro-oxidant. It has been reported that copper levels are significantly raised in different malignancies.

Monocyclic β-lactam and unexpected oxazinone formation: synthesis, crystal structure, docking studies and antibacterial evaluation.

Novel monocyclic β-lactam derivatives bearing aryl, phenyl and heterocyclic rings were synthesized as possible antibacterial agents. Cyclization of imines (3h, 3t) with phenylacetic acid in the presence of phosphoryl chloride and triethyl amine did not afford the expected β-lactams. Instead, highly substituted 1,3-oxazin-4-ones (4h, 4t) were isolated as the only product and confirmed by single crystal X-ray analysis of 4t.

Comparative Analysis of the Antioxidant Activity of Cassia fistula Extracts.

Antioxidant potential of various extracts of Cassia fistula was determined by the DPPH, FRAP, Fe(3+) reducing power, and hydrogen peroxide scavenging assay. Methanolic extracts of Cassia fistula showed the highest amount of phenolic and flavonoid content and reducing capacity, whereas hexane extracts exhibited the lowest level of reducing capacity. The order of antioxidant activity in Cassia fistula extracts displayed from higher to lower level as methanolic extracts of pulp, methanolic extracts of seed, hexane extracts of pulp, and hexane extracts of seed.
