Programmable Thermal Dissociation (PTD) has been used to investigate the chemical speciation of Reactive Gaseous Mercury (RGM, Hg). RGM was collected on denuders and analyzed using PTD. The technique was tested in a field campaign at a coal-fired power plant in Pensacola, Florida. Stack gas samples were collected from ducts located after the electrostatic precipitator and prior to entering the ...
Delivery of small interfering RNA (siRNA) targeted to specific cell types is a significant challenge for the development of RNA interference-based therapeutics. Recently, PTD-DRBD, a double-stranded RNA binding domain (DRBD) fused to the TAT protein transduction domain (PTD), was shown to be effective at delivering siRNA in a non-cell type-specific manner. Here, we evaluated the potential of DR...
BACKGROUND It is unknown whether adverse birth outcomes are associated with maternal highly active antiretroviral therapy (HAART) in pregnancy, particularly in resource-limited settings. METHODS We abstracted obstetrical records at 6 sites in Botswana for 24 months. Outcomes included stillbirths (SBs), preterm delivery (PTD), small for gestational age (SGA), and neonatal death (NND). Among hu...
Primary torsion dystonia (PTD) is a clinically and genetically heterogeneous group of movement disorders, usually inherited in an autosomal dominant fashion with reduced penetrance. The DYT1 gene on chromosome 9q34 is responsible for most cases of early limb-onset PTD. Two other PTD loci have been mapped to date. The DYT6 locus on chromosome 8 is associated with a mixed phenotype, whereas the D...
OBJECTIVES To assess the Gene-Environmental interaction between maternal organochlorine pesticides (OCPs) level and CYP17 gene polymorphism with the risk of preterm delivery (PTD). MATERIALS AND METHODS Maternal blood samples of hundred cases (n = 100) of PTD and of equal number of healthy controls were collected at the time of delivery. OCPs levels were estimated by Gas chromatography system...
The human immunodeficiency virus type 1 (HIV-1) Tat protein transduction domain (PTD), which contains a high proportion of arginine and lysine residues, is responsible for highly efficient protein transduction through the plasma membrane. To identify the role of the PTD sequence motif in transduction, various deletions and substitutions were introduced into the PTD. Tat-green fluorescent protei...
سابقه و هدف: به طور سنتی عملـکرد قلب برروی عملکرد سیستولیک متمرکز بود در حالی که فانکشن دیاستولیک در درجه دوم اهمیت قرار داشت. در سال های اخیر مشخص شده که عملکرد دیاستولیک نقش مهمی در مورتالیتی و موربیدیتی قلبی دارد. فشار خون سبب اختلال عملکرد سیستولیک و دیاستولیک بطن می شود که به علت افزایش پس بار می باشد. در این مطالعه عملکرد دیاستولیک بطن راست در افراد فشار خونی با استفاده از روش (PTD) pulse...
