The homologous series of phenyl and pyridyl substituted bis(acrylamido)alkanes have been synthesized with the aim of systematic analysis of their crystal structures and their solid-state [2 + 2] reactivities. The changes in the crystal structures with respect to a small change in the molecular structure, that is by varying alkyl spacers between acrylamides and/or by varying the end groups (phen...

Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide  (MBA)  as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and  magnetic montmorillonite ( mMT)  nanoclay as nano-...

In order to examine radiation-induced proteins in an extremely radio-resistant bacterium, it became possibleto perform comparative proteomic analysis on radio-resistance Bacillus megaterium WHO as a wildtypestrain for the first time. Variation in cellular proteins profiles of the Bacillus megaterium WHO after 5KGy γ-irradiation were analyzed by two-dimensional poly acryl amide...

Sweden regulates new psychoactive substances, including fentanyl analogs, individually. This reactive scheduling procedure enabled the existence of a recreational market for unscheduled analogs sold from surface webshops. We measure interest in 24 named and impact scheduling. scraped posts threads on Swedish internet forum Flashback.org, 2012–2019. The sample consists with total 8761 posts. con...

The aim of the research work was to chemically modify guar gum(GG) as a pH sensitive co-polymer and formulating intestinal targeting ESO nanoparticles (NPs) using the synthesized co-polymer. Poly acrylamide-grafted-guar gum (PAAm-g-GG) co-polymer was synthesized by free radical polymerization. Chemical modification of PAAm-g-GG by alkaline hydrolysis results in formation of a pH-sensitive co-po...

this study was conducted to determine polymorphism of gola-drb3 in nadushan goat using pcr-rflp. blood samples were randomly taken from 100 goats. dna was extracted from the blood samples using diatom dna prep kit. spectrophotometer and 1% agarose gel were used for determining its quantities and qualities. exon 2 of drb 3.2 gene encompassing 285 bp was amplified with heminested-pcr method in tw...

Objective: To evaluate color and surface gloss stability of bis-acryl resins resin composites, submitted to artificialstaining with cigarette smoke. Material Methods: Specimens each material were prepared (n=15). Two resincomposites (GrandioSO [RCG], Filtek Supreme [RCZ]) five (Luxatemp Star [BisLUX], Protemp4[BisPRO], Structor3 [BisSTR], Visalys Temp [BisVIS] Yprov [BisYPR]) tested. Initial wa...

hydrogels, due to their unique potentials such as high-water content and hydrophilicity are interest for the controlled release of drug molecules. the present study aims to create a controlled-release system through the preparation and characterization of hydrogels based on ph-sensitive polymers such as poly (acrylic acid). poly (acrylic acid), p(aa), hydrogel has been synthesized by radical po...

Objective(s): The quantitative calculation of release data is more facil when mathematics come to help. mathematically modeling could aid optimizing and amending the delivery systems design. Aim of this study is to find out the isoniazid release kinetic. Methods: In this work degradable temperature sensitive dextran-hydroxy ethyl me...
