BACKGROUND Mechano heterocyclic chemistry (MCH) is a recent quickly growing technique in the synthesis of heterocycles and draws the attention of heterocyclic chemists towards the uses of grindstone technique in a solvent free green efficient synthesis of many heterocyclic systems. On the other hand, multicomponent approach has opened the door for the rapid and efficient one-step procedures to ...

The plastid terminal oxidase (PTOX) is a plastoquinol oxidase whose absence in tomato (Solanum lycopersicum) results in the ghost (gh) phenotype characterized by variegated leaves (with green and bleached sectors) and by carotenoid-deficient ripe fruit. We show that PTOX deficiency leads to photobleaching in cotyledons exposed to high light primarily as a consequence of reduced ability to synth...

Silver nanoparticles (AgNPs) have many benefits in the health sector, it has antimicrobial and biomedical Activity. AgNPs can be synthesized by using green chemistry or chemical substances, such as NaBH4. Green synthesis of is an environmentally friendly alternative cost-effective production. Capsicum annuum L. combined with Saffron extract was used to synthesize AgNPs. The biosynthesis, charac...

Green synthesis of nanoparticles as a simple, low-cost and eco-friendly method compared to the Physical chemical methods its materials have become more widely used. In green plants, algae microorganisms their components are used reducing agents for production nanoparticles. meantime, biosynthesis Nanoparticles by due high environmental compatibility reduced energy consumption cost taken into at...

green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. the “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. so, green architecture is building and structure design philosophy that aims at minimal use of non-renewable and/or...

Biopolymeric materials have been utilized for water treatment since ancient times. Consequently, novel sustainable, inexpensive and natural biobased alternatives explored persistently. Amphoteric derivatives of galactomannans are still unexplored rarely used to treat industrial wastes. The present study was synthesize characterize the amphoteric derivative galactomannan, obtained from Cassia to...

Implant-associated infections still pose a serious threat leading to several complications. This study reported an environmentally benign Ag-containing nanocomposite coating with efficient antibacterial property fabricated on the metal implant via electrophoretic deposition (EPD). In such coatings, Ag2O/AgCl mixed with chitosan/gelatin (CS/G) polymers work together to exert the antibacterial pr...

Human umbilical vein endothelial cells were analyzed for the presence of prothrombin. factor VII, protein C, and protein S in culture supernatants and cell extracts using specific radioimmunoassays. Only protein S was detected. Conditioned medium from 24-hour cultures and cell lysates contained 21.7 ng/mL and 88.8 ng/107 cells of protein S, respectively. Intrinsic labeling and immunoprecipitati...
