Application Of Quantum Cascade Lasers To High-Precision Atmospheric Trace Gas Measurements, Ezra Wood, J. Barry Mcmanus, Mark S. Zahniser, David D. Nelson, Joanne H. Shorter, Scott Herndon, Rick Wehr

Ezra Wood

We review our recent results in development of high-precision laser spectroscopic instrumentation using midinfrared quantum cascade lasers (QCLs). Some of these instruments have been directed at measurements of atmospheric trace gases where a fractional precision of 10−3 or better of ambient concentration may be required. Such high precision is needed in measurements of fluxes of stable atmospheric gases and measurements of isotopic ratios. Instruments that are based on thermoelectrically cooled midinfrared QCLs and thermoelectrically cooled detectors have been demonstrated that meet the requirements of high-precision atmospheric measurements, without the need for cryogens. We also describe the design of and results …

Genotype-Phenotype Diversity Of Beta-Thalassemia In Malaysia: Treatment Options And Emerging Therapies, Maryanne Jin Ai Tan Maryanne

Mary Anne Tan Jin Ai

The haemoglobinopathies and thalassemias represent the most common inherited monogenic disorders in the world1. Beta-thalassaemia major is an ongoing public health problem in Malaysia2. Prior to 2004, the country had no national policy for screening and registry for thalassemia. In the absence of a national audit, the true figure of the extent of thalassemia in the Malaysian population was largely presumptive from micro-mapping studies from various research workers in the country. The estimated carrier rate for beta-thalassemia in Malaysia is 3.5-4%. There were 4768 transfusion dependent thalassemia major patients as of May 2010 (Data from National Thalassemia Registry).

Infection Risk Along U.S. Highways? The Case Of A ‘Truckchaser’ Cruising For Truckers, Mona Shattell, Yorghos Apostolopoulos, Sevil Sönmez, Richard Rothenberg, Rose Weitz, John Smith

Mona Shattell

This article explores potential infection risks linked with trucker cruising along U.S. highways. Specifically, the article delineates the settings and social organization of trucker cruising, examines the structure of sex partnerships of truckers and cruisers, and delves into the unique database of one truckchaser who recorded 4,162 sex interactions with 2,499 different truckers during a 13-year period. Concurrent sexual partnerships of bisexual and particularly straight-identified truckers hold increased potential for amplifying infection risk as they enable pathogens to operate as bridges along disparate geographies, demographies, and epidemiologies.

Init Ithoi

This study reports the detection of Acanthamoeba and Naegleria species in 14 swimming pools around Petaling Jaya and Kuala Lumpur, Malaysia. Sampling was carried out at 4 sites (the platforms (P), wall (W), 1 meter from the wall (1) and middle (2)) of each swimming pool. These free living amoebae (FLA) were detected under light and inverted microscopes after being cultured on the surface of non-nutrient agar lawned with Escherichia coli. Acanthamoeba species were detected in higher number of culture plates from all sampling sites of all the swimming pools. While Naegleria, were detected in fewer culture plates at 3 …

Cloning And Expression Of Toxoplasma Gondii Dense Granular Protein 4 (Gra4) In Pichia Pastoris, Init Ithoi

Init Ithoi

GRA4 of Toxoplasma gondii has been shown to prompt IgG, IgM and IgA responses in previous studies and is thus considered one of the major immunogenic proteins from T. gondii that can be used for both diagnostics purposes and vaccine development. This study seeks to clone and express the GRA4 in Pichia pastoris, which has numerous advantages over other systems for expression of eukaryotic proteins. In order to achieve this, the gene was cloned into the pPICZ alpha A expression vector, which was then incorporated into the P. pastoris genome via insertional integration for expression of the recombinant protein, under …

Seroprevalence Survey Of Chikungunya Virus In Bagan Panchor, Malaysia, Chan Yoke Fun

Chan Yoke Fun

In 2006, an outbreak of Chikungunya virus (CHIKV) of the Asian genotype affected over 200 people in Bagan Panchor village in Malaysia. One year later, a post-outbreak survey was performed to determine attack rate, asymptomatic rate, and post-infection sequelae. Findings were compared with recent CHIKV outbreaks of the Central/East African genotype. A total of 180 residents were interviewed for acute symptoms and post-infection physical quality of life and depressive symptoms. Sera from 72 residents were tested for CHIKV neutralizing antibodies. The estimated attack rate was 55.6%, and 17.5% of infected residents were asymptomatic. Arthralgia was reported up to 3 months …

Efficacy Of A Doxycycline Treatment Regimen Initiated During Three Different Phases Of Experimental Ehrlichiosis, Jennifer C. Mcclure, Michelle L. Crothers, John J. Schaefer, Patrick D. Stanley, Glen R. Needham, S A. Ewing, Roger W. Stich

John J Schaefer

Doxycycline is the treatment of choice for canine monocytic ehrlichiosis (CME), a well-characterized disease and valuable model for tick-borne zoonoses. Conflicting reports of clearance of Ehrlichia canis after treatment with doxycycline suggested that the disease phase during which treatment is initiated influences outcomes of these treatments. The purpose of this study was to evaluate the efficacy of a 28-day doxycycline regimen for clearance of experimental E. canis infections from dogs treated during three phases of the disease. Ten dogs were inoculated with blood from E. canis carriers and treated with doxycycline during acute, subclinical, or chronic phases of CME. Daily …

Critical Illness Myopathy, Tazeen S. Ali Dr, Salima Moez Meherali Dr, Yasmin Parpio Dr

Tazeen S Ali Dr

Critical illness myopathy (CIM) is a syndrome of widespread muscle weakness and neurological dysfunction which can develop in critically ill patients receiving intensive care. CIM are often distinguished largely on the basis of specialized electrophysiologic testing or muscle and nerve biopsy and its causes are unknown, though they are thought to be a possible neurological manifestation of systemic inflammatory response syndrome usually developing in patients after a brief period of stay in the Intensive Care Unit (ICU). This case report aims to analyze the Clinical feature, diagnosis and treatment of CIM of 60 years old male case with Chronic Obstructive …

Healthcare In Cuba, Carmen M. Cusack J.D.

Carmen M Cusack

Poor Americans who lack health-insurance or have little opportunity to access specialized or non-emergency medical treatment in the U.S. should be permitted by the U.S. State Department to spend money in Cuba in order to receive inexpensive medical treatment, and should be allowed to stay (and spend) in Cuba as long as necessary in order to receive inexpensive medical treatment. If Americans were permitted by an exception in the Helms-Burton Act to spend money in Cuba and visit for medical purposes, then Cuba would likely treat these Americans for a very low cost. This can be argued because 1) Cuba …

Selected Hormonal And Neurotransmitter Mechanisms Regulating, James L. Sartin, Joseph A. Daniel, Brian K. Whitlock, Robyn R. Wilborn

Brian K Whitlock, PhD, DVM, DACT

Appetite control is a major issue in normal growth and in suboptimal growth performance settings. A number of hormones, in particular leptin, activate or inhibit orexigenic or anorexigenic neurotransmitters within the arcuate nucleus of the hypothalamus, where feed intake regulation is integrated. Examples of appetite regulatory neurotransmitters are the stimulatory neurotransmitters neuropeptide Y (NPY), agouti-related protein (AgRP), orexin and melanin-concentrating hormone and the inhibitory neurotransmitter, melanocyte-stimulating hormone (MSH). Examination of messenger RNA (using in situ hybridization and realtime PCR) and proteins (using immunohistochemistry) for these neurotransmitters in ruminants has indicated that physiological regulation occurs in response to fasting for several …

Investigation Of The Correlation Between Odd Oxygen And Secondary Organic Aerosol In Mexico City And Houston, Ezra Wood, M. Canagaratna, S. Herndon, J. Kroll, T. Onasch, C. Kolb, D. Worsnop, W. Knighton, R. Seila, M. Zavala, L. Molina, P. Decarlo, J. Jimenez, A. Weinheimer, D. Knapp, B. Jobson, J. Stutz, W. Kuster, E. Williams

Ezra Wood

Many recent models underpredict secondary organic aerosol (SOA) particulate matter (PM) concentrations in polluted regions, indicating serious deficiencies in the models' chemical mechanisms and/or missing SOA precursors. Since tropospheric photochemical ozone production is much better understood, we investigate the correlation of odd-oxygen ([Ox]≡[O3]+[NO2]) and the oxygenated component of organic aerosol (OOA), which is interpreted as a surrogate for SOA. OOA and Ox measured in Mexico City in 2006 and Houston in 2000 were well correlated in air masses where both species were formed on similar timescales (less than 8 h) and not well correlated when their formation timescales or location …

Health Benefits Of Increased Walking For Sedentary, Generally Healthy Older Adults: Using Longitudinal Data To Approximate An Intervention Trial, Paula Diehr

Paula Diehr

BACKGROUND: Older adults are often advised to walk more, but randomized trials have not conclusively established the benefits of walking in this age group. Typical analyses based on observational data may have biased results. Here, we propose a "limited-bias," more interpretable estimate of the health benefits to sedentary healthy older adults of walking more, using longitudinal data from the Cardiovascular Health Study. METHODS: The number of city blocks walked per week, collected annually, was classified as sedentary (<7 blocks per>week), somewhat active, or active (>or=28). Analysis was restricted to persons sedentary and healthy in the first 2 years. In Year …
