Individual approaches to the diagnosis and management of penicillin allergy are practiced    by clinicians.   This cross-sectional survey of physicians was aimed at exploring their ways of dealing with diagnosis and management of penicillin G allergy.   Of the 235 respondents, 63% believed patients’ self-reported history of penicillin allergy and avoided using penic...

An (n, r)-arc is a set of n points of a projective plane such that some r, but no r + 1 of them, are collinear. The maximum size of an (n, r)-arc in PG(2, q) is denoted by mr(2, q). Using some good blocking sets in PG(2, 23) we establish that m22(2, 23) ≥ 484, m21(2, 23) ≥ 461, m20(2, 23) ≥ 437, m19(2, 23) ≥ 411, m18(2, 23) ≥ 385 and m17(2, 23) ≥ 360.

Random screening for inhibitors of chromosome partitioning in Escherichia coli was done by the anucleate cell blue assay. A novel S-benzylisothiourea derivative, S-(3,4-dichlorobenzyl)isothiourea, tentatively named A22, was found to induce spherical cells and spherical anucleate cells in E. coli. Mecillinam, a specific inhibitor of penicillin-binding protein 2, which induces spherical cells in ...

background and purpose: highly consumption of antibiotics and their entrance into the environment has increased concerns all over the world. these compounds enter to the environment through an incomplete metabolism and a considerable amount of them cannot be removed using usual waste filtration systems. therefore, the present study aimed to investigate the feasibility of using ultraviolet radia...

Introduction: The presence of antibiotics due to toxicity and sustainability as well as organic compounds as a combination of hard biodegradable wastewater is an undesirable issue in many industries. The aim of this study was to evaluate the efficiency of dissolved air flotation process for aniline and penicillin G removal from aqueous solutions. Methods: This was an empirical-lab study to w...

Validation process is a program for ensuring products with proven acceptable and predetermined specification. The LAL test used for detection of endotoxin in the sterile parenteral products is one of the tests that require validation. During this study, validation of 12 parenteral antibiotics including penicillin and cephalosporin have been done using gel clot method and obtained results which ...

BACKGROUND A history of penicillin allergy in patients is common, but only 10-15 % are truly allergic. While the gold standard for diagnosing penicillin allergy is challenge, it is not recommended that this be done without first carrying out diagnostic skin testing. This is carried out with the major determinant benzylpenicilloyl (PPL) and the minor determinant mixture (MDM), consisting of peni...
