The quality assurance (QA) of radiographic images based on the operating conditions of X-ray equipment is essential for good image quality, accurate medical diagnostics and for the prevention of health professionals and patients to unnecessary doses of ionizing radiation. This paper presents a historical analysis of 1,635 Quality Assurance Technical Reports of Health Institutions in the state o...

Comprehensive studies of the frequencies and absolute numbers of the various cell lineages that synthesize IL-17 in the blood and corresponding gastrointestinal (GI) tissues, their correlation with CD4(+) Tregs, CD8(+) Tregs, total and IFN-α synthesizing plasmacytoid dendritic cells (pDC) relative to plasma viral load in SIV infection has been lacking. The unique availability of SIV infected rh...

Linkage analysis is useful in investigating disease transmission dynamics and the effect of interventions on them, but estimates of probabilities of linkage between infected people from observed data can be biased downward when missingness is informative. We investigate variation in the rates at which subjects' viral genotypes link across groups defined by viral load (low/high) and antiretrovir...

Abstract Gamma-ray shielding properties of eight different metallic glasses based on Cu x Zr100- : = 35 (Cu35Zr65) ? 70 (Cu70Zr30) were determined using Monte Carlo simulations and Phy-X/PSD software. A typical gamma-ray transmission setup has been modeled in MCNPX code. The general trend the linear attenuation coefficients ( ? ) was reported as Cu35Zr65 < Cu40Zr60 Cu45Zr55 Cu50Zr50 Cu55Zr45...

C ombination nucleos(t)ide analogs (NUCs) had been advocated as the initial treatment of chronic hepatitis B when lamivudine and adefovir dipivoxil (ADV) were the only approved NUCs for hepatitis B. These drugs had weak antiviral activity and/or low barrier to resistance with rates of genotypic resistance of 70% and 29%, respectively, after 5 years of continuous treatment. Borrowing from lesson...

Background: X-ray equipment used for radiographic examination according to Bapeten regulations must undergo a compliance test, both new installation and relocating. The Panoramic Chepalometry in the Department of Radiodiagnostics Radiotherapy Techniques Semarang is device has undergone relocation from initial installation. In addition, unique condition direct image processing or radiography, so...

Background: This study investigated the γ-rays shielding properties of some building materials in Sudan has been investigated. Materials and Methods: Photons attenuation coefficients half value layer (HVL) were experimented using Cs-137 Co-60 sources. The measurements performed to gauge intensity radiation when unshielded, specific thickness selected samples was examined, an ion chamber placed ...

A cross-sectional seroepidemiological survey of leishmaniasis was carried out among children and adults from four villages and one district of Denizli province located in the Southern Aegean Region of Turkey where 14 human visceral leishmaniasis (HVL) cases including 4 adults were reported between 1993 and 2000. Blood samples were taken from 329 children, 217 adults and 140 dogs and a physical ...
