One of the primary causes for the failure of glass ionomer cement (GIC) is secondary caries. To enhance the anti-microbial performance of GIC without affecting its mechanical properties, chlorhexidine (CHX) was encapsulated in expanded-pore mesoporous silica nanoparticles (pMSN) to synthesize CHX@pMSN. CHX@pMSN was added at three mass fractions (1%, 5%, and 10% (w/w)) to GIC powder as the exper...

cyclizine (1-benzhydryl-4-methyl-piperazine, cas 82-92-8, cyc, i), a piperazine derivative, belongs to h1 antihistamine group of drugs that shows such pharmacological properties as anti-inflammatory, anti-allergic and anti-platelet effects, similar to other h1-receptor antagonists. in this study, two new tolyl and cumene derivatives of i (1-ethyl-4-[(p-isopropylphenyl) (p-tolyl) methyl]-piperaz...

Abstract Most biological protein fibers exhibit extraordinary mechanical performance at room temperatures but inferior freezing resistance. Maintaining fiber's high strength and toughness under subzero conditions remains a great challenge. Herein, class of tolerant is reported with favorable ice‐phobic capacity cryogenic by genetic engineering. Inspired nature, chimeric recombinant proteins con...

background: neonatal lupus erythematosus is an uncommon disease. congenital complete heart block (cchb) usually happens in neonates with maternal systemic lupus erythematosus. the most prevalent presentation of cchbis bradycardiathatcanbediagnosed through an electrocardiogram. case report: here in, we present the case of a full-term male neonate with gestational age of 37 weeks and birth weight...

introduction: sodium hypochlorite (naocl) is an effective antimicrobial irrigant, however its toxic effects and deterrent odor are not ideal. carvacrol is an edible plant extract with anti-inflammatory and anti-bacterial properties that is effective against enterococcus ( e ) faecalis . the aim of this study was to evaluate carvacrol's antibacterial efficacy against e. faecalis bacteria as a fi...

in view of the importance environmental pollution caused by plastic food packaging, in recent years there is a considerable interest in edible films and coating based on polysaccharides, proteins, lipids or combination of them. edible coatings also serve as carriers of food additives such as anti-browning and antimicrobials agents, colorants, flavor, nutrients and spices, so act as active packa...
