  • This book contains chapters on nanocomposites for engineering hard materials for high performance aircraft, rocket and automobile use, using laser pulses to form metal coatings on glass and quartz, and also tungsten carbide-cobalt nanoparticles using high voltage discharges. A major section of this book is largely devoted to chapters outlining and applying analytic methods needed for studies of nanocomposites. As such, this book will serve as good resource for such analytic methods.

  • Lasers have become integral to the modern practice of medicine in the fields of dermatology, plastic surgery, otolaryngology, and phlebology. With the skin being the most accessible organ in the body, many cutaneous disorders and conditions are ideally suited to treatment by laser technology. Lasers are safely used to destroy or alter epidermal and dermal processes and lesions comprising blood vessels or pigment.

  • This report, published by the UN Millennium Project, examines the global burden of diseases and risks related to sexual and reproductive health (SRH), analyses the implications for the Millennium Development Goals, and asks what needs to be done. Key findings include that millions of women lack access to family planning services they need and want. The unmet need for contraception is especially acute among adolescents in the developing world. One in 16 women in sub-Saharan Africa dies from complications of pregnancy and childbirth, compared with one in every 2800 in...

  • Table 125-3 Controlling Antibiotic Resistance: Approaches to Consider Conduct surveillance for antibiotic resistance. Perform molecular typing (e.g., pulsed-field gel electrophoresis) when rates increase. For clonal expansion (e.g., single-strain outbreaks): Stress hand hygiene (alcohol hand rub and universal gloving); monitor adherence and give feedback. For polyclonal expansion (e.g., multistrain outbreaks): Stress antibiotic prudence (consider antibiotic rotation for ICUs); monitor adherence and give feedback.

  • Distinguishing Cardiogenic from Noncardiogenic Pulmonary Edema The history is essential for assessing the likelihood of underlying cardiac disease as well as for identification of one of the conditions associated with noncardiogenic pulmonary edema. The physical examination in cardiogenic pulmonary edema is notable for evidence of increased intracardiac pressures (S3 gallop, elevated jugular venous pulse, peripheral edema), and rales and/or wheezes on auscultation of the chest.

  • Physical Findings Patients with pneumococcal pneumonia usually appear ill and have a grayish, anxious appearance that differs from that of persons with viral or mycoplasmal pneumonia. Temperature, pulse, and respiratory rate are typically elevated. Elderly patients may have only a slight temperature elevation or may be afebrile. Hypothermia may be documented instead of fever and is associated with increased morbidity and mortality. Pleuritic chest pain may cause diminished respiratory excursion (splinting) on the affected side.

  • As new species emerged and evolved into disparate new forms, other species became extinct. And just as the origin of species and disparity form large-scale patterns, extinctions have formed patterns of their own. One of those patterns is illustrated in . It shows how the extinction rate has gone up and down over the past 540 million years. A few pulses of extinctions stand out above the others. These mass extinctions were truly tremendous cataclysms. The biggest of all, which occurred 250 million years ago, claimed 55% of all gen- era.

  • The interaction of xenon with copper⁄6-hydroxydopa (2,4,5-trihydroxy-phenethylamine) quinone (TPQ) amine oxidases from the plant pulses lentil (Lens esculenta) and pea (Pisum sativum) (seedlings), the perennial Mediter-ranean shrub Euphorbia characias(latex), and the mammals cattle (serum) and pigs (kidney), were investigated by NMR and optical spectroscopy of the aqueous solutions of the enzymes.

  • TheCa 2+ -ATPaseof skeletalmuscle sarcoplasmic reticulum (SERCA), an integral membrane protein, becomes irre-versibly inactivatedin vitroby the addition of a single bolus of peroxynitritewithaK0.5of 200–300lM, and this results in a large decrease of theATP-dependentCa 2+ gradient across the sarcoplasmic reticulum (SR) membranes. The inactiva-tion of SERCA is raised by treatment of SR vesicles with repetitivemicromolar pulses of peroxynitrite.

  • To test thioredoxin resistance to oxidizing free radicals, we have studied the one-electron oxidation of wild-type thio-redoxin and of two forms with the point mutations D30A and W35A, using azide radicals generated byc-ray or pulse radiolysis. The oxidation patterns of wild-type thioredoxin and D30A are similar. In these forms, Trp35 is the primary target and is repaired by one-electron reduction; first by intramolecular electron transfer from tyrosine, and then fromother residues. Conversely, duringoxidationofW35A, Trp13 is poorly reactive.

The most fundamental and revealing sources of policy documentation relative to oxytocin, misoprostol, and magnesium sulfate are the essential medicines lists (EMLs) and standard treatment guidelines.

  • Glycoprotein (GP) V is noncovalently linked to GPIba, GPIbband GPIX within the platelet GPIb–V–IX complex, a receptor for von Willebrand factor and thrombin. Two functions have been ascribed to GPV, namely, the modula-tionof thrombin- andcollagen-dependent platelet responses. The biosynthesis of this molecule was investigated in pulse– chase metabolic labelling experiments performed in CHO cell lines transfected with GPV, alone or in the presence of GPIb–IX.

  • In both industrial fermenters and in their natural habitats, microorganisms often experience an inhomogeneous and fluctuating environment. In this paper we mimicked one aspect of this nonideal behaviour by imposing a low and oscillating extracellular glucose concentration on nonoscillating suspensions of yeast cells. The extracellular dynamics changed the intracel-lular dynamics – which was monitored through NADH fluorescence – from steady to equally dynamic; the latter followed the extracellular dynamics at the frequency of glucose pulsing....

  • Metabolically unstable proteins are involved in a multitude of regulatory networks, including those that control cell signaling, the cell cycle and in many responses to physiological stress. In the present study, we have deter-mined the stability and characterized the degradation process of some members of the Gq class of heterotrimeric G proteins. Pulse-chase experi-ments in HEK293 cells indicated a rapid turnover of endogenously expressed Gaq and overexpressed Gaq and Ga16 subunits.

  • One-electron oxidation of six different c-type lysozymes from hen egg white, turkey egg white, human milk, horse milk, camel stomach and tortoise was studied by gamma-and pulse-radiolysis.In the first step, one tryptophan side chain is oxidized to indolyl free radical, which is produced quantitatively.As shown already, the indolyl radical subse-quently oxidizes a tyrosine side chain to the phenoxy radical in an intramolecular reaction.However this reaction is not total and its stoichiometry depends on the protein.
