Phosphorescence signaling provides a valuable alternative to conventional bioimaging based on fluorescence. The benefits of using phosphorescent molecules include improved sensitivity and capabilities for effective elimination of background signals by time-gated acquisition. Cyclometalated Ir(III) complexes are promising candidates for facilitating phosphorescent bioimaging because they provide...

The importance of assessing and treating pain was made salient recently when the Joint Commission on Accreditation of Healthcare Organizations (JCAHO, 2000) declared that pain should be regarded as the fifth vital sign. Yet, the literature suggests that problems with undertreatment of pain have only improved modestly. In the 1970s and 1980s, scathing editorials were published by such journals a...

The cells of cerebrospinal fluid are usually examined in a Fuchs-Rosenthal chamber using a nuclear stain. By this means it is possible to distinguish between polymorphonuclear leucocytes and lymphocytes, but difficulties arise when other types of cell are predominant. If films can be made of a quality comparable with that expected for haematological diagnosis, various other cell types are found...

Based on preliminary assumptions and analysis, mathematical models have been used to estimate the behavior of the fires in the twin towers of the World Trade Center (WTC) on September 11, 2001. The hijacked-plane collision with each tower produced significant structural damage, generated a spectacular external fireball, and started burning within the tower. The fuel consumed by the fireball was...

Recently, a new metabolic link between fatty acid de novo biosynthesis and biosynthesis of poly(3-hydroxy-alkanoate) consisting of medium-chain-length constituents (C(6) to C(14)) (PHA(MCL)), catalyzed by the 3-hydroxydecanoyl-[acyl-carrier-protein]:CoA transacylase (PhaG), has been identified in Pseudomonas putida (B. H. A. Rehm, N. Krüger, and A. Steinbüchel, J. Biol. Chem. 273:24044-24051, 1...

Excesses of sulfur-36 in sodalite, a chlorine-rich mineral, in a calcium- and aluminum-rich inclusion from the Ningqiang carbonaceous chondrite linearly correlate with chorine/sulfur ratios, providing direct evidence for the presence of short-lived chlorine-36 (with a half-life of 0.3 million years) in the early solar system. The best inferred (36Cl/35Cl)o ratios of the sodalite are approximate...

Background and Objectives: Iltehabe Unqur Rehm (cervicitis) refers to the inflammation of the cervix which may be acute or chronic causing various complications. Hence it has been decided to conduct a clinical trial for its management with Irsa. Method: Irsa was given in the form of majoon, 10 gm in two divided doses after menses for 15 days for three cycles. Extract of Irsa (10ml) was prepared...
