PROBLEM Until 2005, the quality of rapid diagnostic human immunodeficiency virus (HIV) testing was not monitored and no regular technical support was provided to hospital laboratories in Myanmar. APPROACH The national reference laboratory introduced a national external quality assessment scheme. The scheme involved (i) training laboratory technicians in HIV testing and in the requirements of ...

BACKGROUND The Strengthening Laboratory Management Toward Accreditation (SLMTA) programme is designed to build institutional capacity to help strengthen the tiered laboratory system. Most countries implement the SLMTA three-workshop series using a centralised model, whereby participants from several laboratories travel to one location to be trained together. OBJECTIVES We assessed the effecti...

in number (16 of 22) of infants in the dutch laboratory rabbit breeding colony, in aged 45-65 days old, hair loss (alopecia) seen at the top of the head and around a week after the hair fall, was created in a state of complete alopecia. for determination of the cause of hair loss, after the observation and palpation the alopecic area, there have not been any swelling, abscesses, tumors. in s...

BACKGROUND Public health laboratories form the foundation on which today's clinical laboratory practice in Cameroon is built. The advent of the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme in 2009 empowered the Bamenda Regional Hospital Laboratory (BRHL) to improve its working culture, practices and management. OBJECTIVES To evaluate the results of SLMTA implemen...

Seasonal variation and planktonic abundance has profound effects on the attachment of V. cholerae devastating agent for causing cholera. As crustacean plankton is primitive carrier cholera bacterium, which stage most efficient to however a curious interrogation resolve. Here in this experiment, laboratory microcosms were prepared with estuarine Mathbaria water, saline Paikgacca water fresh lake...

BACKGROUND Seamless ligation cloning extract (SLiCE) is a simple and efficient method for DNA assembly that uses cell extracts from the Escherichia coli PPY strain, which expresses the components of the λ prophage Red/ET recombination system. This method facilitates restriction endonuclease cleavage site-free DNA cloning by performing recombination between short stretches of homologous DNA (≥ 1...

The tandem differential mobility analyzer (TDMA) technique was applied to determine the hygroscopicity and volatility of atmospheric ultrafine particles in three sites of urban Gwangju, industrial Yeosu, and coastal Taean in South Korea. A database for the hygroscopicity and volatility of the known compositions and sizes of the laboratory-generated particles wasfirst constructed for comparison ...

Generic water quality guidelines (WQGs) are developed by countries/regions as broad scale tools to assist with the protection of aquatic ecosystems from the impacts of toxicants. However, since generic WQGs cannot adequately account for the many environmental factors that may affect toxicity at a particular site, site-specific WQGs are often needed, especially for high environmental value ecosy...

Real time monitoring of suspended sediment (SS) carbon content and particle size information is essential to understand SS transport mechanisms processes. However, limited in situ methods are available, manual unattended sampling makes high frequency observation challenging. Based on evidence that optical measurements concentration dependent composition, we hypothesize mean can simultaneously b...
