The reaction of benzoic acid with the uranyl(V) complex [(UO(2)Py(5))(KI(2)Py(2))] in pyridine leads to immediate disproportionation with formation of a hexanuclear U(IV) benzoate cluster, a bis-benzoate complex of uranyl(VI) and water.

Among infants exposed to human immunodeficiency virus type 1 (HIV-1), detection of viral infection at birth was increased by 39% (95% confidence interval, 19%-47%) by increasing DNA input from dried blood spots into polymerase chain reaction. Infants with low concentrations of HIV-1 at birth may be the best target population to evaluate whether immediate antiretroviral therapy can prevent long-...

A 48 year old lady presented with jaundice and exertional breathlesness. Her laboratory reports showed anaemia, reticulocytosis, leucocytosis, elevated Lactate Dehydrogenase (LDH), alkaline phosphatase levels, hyperbillirubinemia and positive direct Coomb's test. After ruling out all the other causes of autoimmunity and hemolytic anemia, she was diagnosed as leukemoid reaction due to autoimmune...

Lipopolysaccharides of the seven Fisher immunotypes of Pseudomonas aeruginosa gave cross-precipitation in many antipneumococcal sera. The reaction of Pseudomonas type IV in type 25 antipneumococcal serum was immediate and heavy: 93 micrograms of antibody nitrogen per ml. Correlations are described, mainly between the structures of the O-chains of the immunotypes and their specificities as shown...

A practical electrochemical oxidation of unactivated C-H bonds is presented. This reaction utilizes a simple redox mediator, quinuclidine, with inexpensive carbon and nickel electrodes to selectively functionalize "deep-seated" methylene and methine moieties. The process exhibits a broad scope and good functional group compatibility. The scalability, as illustrated by a 50 g scale oxidation of ...

Fluorescein is associated with minor adverse effects during retinal angiography, and most of these effects are not severe and not related to immunological mechanism. However, on rare occasions, anaphylatoid reaction can occur, and fatalities involving fluorescein have been described. Life threatening complications after intravenous injection of sodium fluorescein require immediate intervention....

This report describes a rare severe tissue reaction, as demonstrated in clinical photographs, to nylon sutures and illustrates how simple immediate removal of sutures isolates the irritant stimulus and results in rapid resolution, without the risk, cost and inconvenience of antibiotic treatment.
