introduction: ubiquicidin 29-41 (ubi) is a fragment of the cationic antimicrobial peptide that is present in various species including humans. the purpose of this study was to investigate radiochemical and biological characteristics of [6-hydrazinopyridine-3-carboxylic acid (hynic)]-ubi 29-41 designed for the labeling with 99mtc using tricine as coligand. methods: synthesis was preformed on a ...

cis-[RuCI2(depehl (1) (depe = Et2PC2H4PEt2) is obtained in excellent yield and high isomeric purity by the reaction of [RuCliDMSO)41 with two equivalents of depe in acetone 01" ethyl acetate under reflux conditions. One of the chloride ligands is labile and readily displaced by CH3CN to afford the cationic monosubstitution product cis-[RuCl(CH3CN)(depe)21 +(2), which was isolated as the PF 6 sa...

The objective of this study was to evaluate the possibility of photoinduced stack/rod electron transfer in surface "zipper" architectures composed of stacks of blue (B) naphthalenediimides (NDIs) along strings of oligophenylethynyl (OPE) rods. The synthesis and characterization of anionic and cationic multichromophoric OPE-B systems are reported. Absorption spectra suggest that in OPE-B systems...

Background & objectives: Pharmaceutical wastewater contains high concentrations of organic matter, high salt and difficult biodegradability, so it must be treated before discharge to the environment. In this study, it is aimed to evaluate the treatment of pharmaceutical wastewater (methadone feedstock and neutralized capecitabine) using chemical and biological methods. Methods: The laboratory ...

Cellular blue nevus is an uncommon pigmented tumor in the conjunctiva, where it generally appears as a deep, circumscribed, pigmented conjunctival mass. We report a case of conjunctival blue nevus that clinically resembled primary acquired melanosis and gave rise to conjunctival melanoma. A 41-year-old man developed a diffuse pigmented mass in the inferior fornix of his left eye. Over a 20-year...

Cationic dyes such as methylene blue are among the most widely used dye in textile and paper industry. The waste produced causes environmental pollution is harmful to human health. Thus, wastewater treatment becomes an important aspect of reducing this problem. Adsorption a very effective method for treating various wastewaters due its high selectivity capacity. This study aims prepare adsorben...

Peritoneal adhesions are challenging in abdominal surgery. In spite of different kinds of treatments still no definitive and effective treatment is suggested. To determine the prevention effects of intraperitoneal (ip) methylene blue in post surgical adhesion formation 44 rabbits were randomly divided in two groups of equal number. Group I received an intra peritoneal injection of a 1% suspensi...

The human nasopharynx has a commensal bacterial flora which may become pathogenic (invasive), causing pneumonia, sepsis, meningitis and otitis media. A major virulence factor in this pathogenesis is the presence of a polysaccharide bacterial capsule, the production of which is controlled by a number of interacting variables (including temperature and capsule gene presence/expression/phase varia...

Silver nanoparticles (AgNP) formation mediated by fibres in paper can be a promising process for optical sensing applications with high sensitivity and low cost. Thus, the aim of this thesis was to develop a paper-based sensor to quantify the concentration of analyte. The work focused on investigating the role of interactions between silver ions-cellulosic hydroxyl groups and analyte molecules ...
