ments, nor to protect the wound from the acid which often caused symptoms of poisoning. Septic complications continued to manifest themselves, though to a less extent and in less severe forms. Edward Lawrie, who had recently joined the service after having been indoctrinated by Lister and Syme in the antiseptic system in the Edinburgh Infirmary, was the Resident Surgeon. He triedJ to introduce ...

This article reviews nonsurgical approaches for the management of periodontal diseases. A brief review of the pathogenesis of periodontitis allows the reader to identify the potential points of intervention. Assessment of risk factors for periodontitis and the potential for risk reduction are introduced as the first part of a three-pronged approach to therapy. Antimicrobial approaches, includin...

We review here the selectively infective phage (SIP) technology, a powerful tool for the rapid selection of protein-ligand and peptide-ligand pairs with very high affinities. SIP is highly suitable for discriminating between molecules with subtle stability and folding differences. We discuss the preferred types of applications for this technology and some pitfalls inherent in the in vivo SIP me...

Concentrations of three anti-infective agents in tear film were monitored after one topical application in rabbits. Ofloxacin concentrations exceeded the MIC for 90% of the organisms tested (MIC90) (gram-negative and gram-positive organisms) for 240 min. Tobramycin concentrations exceeded the MIC90 for 10 min. Gentamicin concentrations exceeded the MIC90 for 20 min for gram-positive organisms a...

In the asymmetric unit of the title compound, C(16)H(11)FO(5)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angle between the 2H-chromene ring and the 4-fluoro-phenyl ring is 2.17 (8)°. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C-C-S-O torsion angle = 166.00 (14)°], whereas the other O atom lies well bel...

The clinical outcome of anti-infective treatment is determined by both PK and PD properties of the antibiotic. Only the free tissue concentrations of antibiotics at the target site, which are usually lower than the total plasma concentrations, are responsible for therapeutic effect. The free antibiotic concentrations at the site of action are a more appropriate PK input value for PK-PD analysis...

Urea and sulfonamide derivatives of 1 exhibit ON-OFF and OFF-ON switchable fluorescent and colorimetric responses upon protonation. The magnitude of the fluorescence event is dictated by the anion, resulting in a rare, fully organic "turn-on" fluorescent sensor for chloride.
