Background & Aims of the Study: The Horizontal roughing filters (HRF) are generally formed with three layers. The size of the course at the beginning of the flow path is large and at the end is small. This kind of layering increases absorption capacity while the solids entering the bed–depth gradually separate because of the decline in the holes’ diameters. This stu...

Objective-  To evaluate kidney hemodynamic response including blood flow velocity in segmental arteries shortly after administration of various dose of saffron extract (10, 40 and 90 mg/kg).   Design- Technical assessment, experimental study.   Animals- 20 healthy male Sprague-Dawley rats.   Procedures- In this study, using a real-time pulsed doppler analysis, kidney hemodynamic response inc...

The gypsy moth (Lymantria dispar) is nonpermissive for Autographa californica nucleopolyhedrovirus (AcNPV) infection. We previously isolated a gene, host range factor 1 (hrf-1), from L. dispar nucleopolyhedrovirus that promotes AcNPV replication in Ld652Y cells, a nonpermissive L. dispar cell line (S. M. Thiem, X. Du, M. E. Quentin, and M. M. Berner, J. Virol. 70:2221-2229, 1996). In the presen...

The transverse motions of nearby dwarf spheroidal (dSph) galaxies contribute line-of-sight components that increase with angular distance from the dSph centers, inducing detectable gradients in stellar redshift. In the absence of an intrinsic velocity gradient (e.g., due to rotation or streaming), an observed gradient in the heliocentric rest frame (HRF) relates simply to a dSph’s systemic prop...

background and aim: clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. the aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (psp) and cbct in the detection of horizontal root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experim...

Introduction Estimation of hemodynamic response associated with brain activation following various types of events, i.e., motor, sensory, cognitive, often relies on the solving of a deconvolution problem. Deconvolution methods employed to date have been limited in their ability to investigate details of the hemodynamic response function (HRF) due to the limited temporal resolution of the deconv...

The aim of this study was: echocardiographical assessment of cardiac alterations in late-preterm newborns with hypoxic respiratory failure (HRF), and, study serum pentraxin-3 (PTX-3) in relation to the severity of respiratory impairment and to some echocardiographic parameters (i.e. ejection fraction (EF), stroke volume (SV) and cardiac output (CO). We enrolled in this study 40 newborn infants ...

or had significant heart failure. Often the hemodynamic response to plasma volume expansion within fifteen hours after uncomplicated acute myocardial infarction is abnormal, but it is not useful in predicting prognosis. The abnormal hemodynamic response may be transient, improving during early convalescence. It represents an interaction between left ventricular compliance and function, both of ...

An understanding of the relationship between changes in neural activity and the accompanying hemodynamic response is crucial for accurate interpretation of functional brain imaging data and in particular the blood oxygen level-dependent (BOLD) fMRI signal. Much physiological research investigating this topic uses anesthetized animal preparations, and yet, the effects of anesthesia upon the neur...

Host range factor 1 (HRF-1) of Lymantria dispar multinucleocapsid nucleopolyhedrovirus promotes Autographa californica MNPV replication in nonpermissive Ld652Y cells derived from L. dispar. Here we demonstrate that restricted Hyphantria cunea NPV replication in Ld652Y cells was not due to apoptosis but was likely due to global protein synthesis arrest that could be restored by HRF-1. Our data a...
