The most common path of Human exposure to Bisphenol-A-(BPA) is by oral intake. It involves genotoxicity, oxidative stress, endocrine disruption, mutagenicity, and carcinogenicity in both in vitro and in vivo models. Melatonin has known as a freeradical scavenger and powerful antioxidant agent. This study was initiated to investigate the role of melatonin on viability and genetic disorders of Normal Human Gingival Fibroblasts (HGF), Colon cancer (MKN45), and Bone marrow stem cell lines exposed to BPA. For this purpose, MTT and Comet assays were performed to evaluate the cytotoxicity and genotoxicity properties of BPA and Melatonin role. The results of the present study showed that BPA exposure resulted in increased oxidative stress parameters including MDA, ROS, and decreased GSH content. The current study demonstrated the cytotoxicity and genotoxicity effects of BPA and the protective role of melatonin for preventing cytotoxicity and DNA damage induced by BPA.

A series of Novel 1-aryl-5-hepta-O-benzoyl-β-D-lactosyl-2-S-benzyl-2, 4-isodithiobiurets were synthesized by the interaction of 1-aryl-2-S-benzyl isothiocarbamides and hepta-O-benzoyl-β-D-lactosyl isothiocyanate in benzene medium. The identities of these newly synthesized N-lactosides have been established on the basis of usual chemical transformations and IR, 1H NMR and Mass spectral analysis. The polarimetric study of all compounds was carried out. The study of S-and N-glycosides is important in carbohydrate chemistry. Sugar isothiocyanate is good precursors and versatile intermediate for synthesis of S- and N-glycosides. Carbohydrates play an important role in the number of biological events and play an important role in their synthetic strategy as well. Similarly the amino sugars are an important class of glycosidase inhibitors and are arousing great interest as potential therapeutic agents.
Sphere-shaped solid lipid nanoparticles (SLNs) containing Sulfasalazine (SSZ) were prepared by optimized solvent emulsification diffusion technique and evaluated for their zeta size, morphology, entrapment efficiency, loading capacity, in vitro, in-vivo drug release and stability studies. Initially twelve (12) formulations for unloaded SLNs were prepared using four variables i.e. amount of lipid (stearic acid), amount of surfactant (tween-80), amount of co-surfactant (PVP) and stirring time. All 12 formulations were evaluated for their zeta size and Polydispersity Index (PDI). After determining optimal condition for unloaded SLNs the best formulation i.e. BFM-11 was designated for drug loading. Five different formulations were prepared on basis of drug lipid ratio and evaluated for percent entrapment efficiency, percent drug loading capacity, zeta size, PDI and Zeta Potential. The drug release profile of all five formulations were scanned in dissolution media, SEM image of optimized formulation SFM-3 clearly indicated that particles were spherical and nano-ranged. Differential Scanning Calorimetry (DSC) and X-Ray Diffractometry (XRD) results showed that drug was converted from crystalline to amorphous state while FTIR showed that there was no interaction between drug and lipid.
Electronic plates are among the common and exploitable sources of gold that are widely used in several types of industry. Gold (Au) element is an electronic particle that can be used in a variety of applications such as medicine, engineering, and biology by adjusting its surface functionality and particle size. A noteworthy feature of this material is the changes in its properties that occur with the variation in its particle size. In other words, by transferring its particle size from micrometer to nanometer, the surface-area-to-volume ratio increase such that new structural properties emerge, change, or improve. Various physical, chemical, and biological methods are used to make these particles. Among these methods, chemical and multi-material combinations are used as reductants. Tests such as Fourier-Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM) have confirmed high-quality production and proper extraction of gold particles on a nanometer scale from electronic plates.
Anthocyanins are the basis of the angiosperms colour, 3-deoxyanthocyanins and sphagnorubin play the same role in mosses and ferns and auronidins are responsible for the colour in liverworts. The separation of the ancestors of each of these lineages occurred in different periods of land plant evolution, therefore, our thesis is that chemical evolution of the colour systems accompanied plant evolution. The colour system of cyanidin-3-O-glucoside (kuromanin) as a representative compound of simpler anthocyanins was here fully characterized by stopped flow. This type of anthocyanins cannot confer significant colour to plants without intra or intermolecular interactions, complexation with metals or supramolecular structures as in Commelina communis. The anthocyanin’s colour system was compared with the one of 3-deoxyanthocyanins and riccionidin A the aglycone of auronidins. The three systems follow the same sequence of chemical reactions, but the respective thermodynamic and kinetics is dramatically different.

Recovered paper and board has become a valuable raw material resource in the manufacture of paper, from both an economic and environmental sustainability point of view. However, the paper recycling process faces several challenges related to ‘stickies’ present in the recovered paper and board. Stickies refer to the tacky, hydrophobic, pliable organic materials present in recovered paper and board that are derived from pressure sensitive and hot melt adhesives. It is estimated that stickies related problems are costing United States paper manufacturers several hundred million dollars per year, mainly due to product quality problems such as holes, dark spots and reduced strength of the finished products. Run-ability problems such as sheet breaks that arise due to deposits on the wire, felts, press rolls, drying cylinders and calenders also result in long periods of downtime for cleaning. This study proposes new methodologies for the measurement of micro- and potential secondary stickies that are difficult to remove from paper recycling processes due to their small size.

Most of the people assume that water is just water. They know it is essential in order to survive, but they aren�??t really aware of its nutritional value. Water can do several wonders for our body, it is especially crucial today, in the times of Corona. This is because water is one of the most natural immunity boosters and source of the minerals that can power up our body. Water keeps our body at a constant temperature, it helps eliminate waste, it facilitates digestion and, above all, it is necessary for the transportation of nutrients that are essential for the proper functioning of cells. Minerals in water are important for the human health, since they appear in ionic form and are generally more easily absorbed in the intestines from water than they are from food. The aim of this article is to review the role of water as natural immunity booster and source of the minerals.
