Renal Power Doppler Ultrasonographic Evaluation of Children With Acute Pyelonephritis [PDF]

open access: yesActa Medica Iranica, 2011
Urinary tract infections are common in children. The available gold standard method for diagnosis, Tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Transcutaneous measurement of volume blood flow [PDF]

open access: yes
Blood flow velocity measurements, using Doppler velocimeter, are described. The ability to measure blood velocity using ultrasound is derived from the Doppler effect; the change in frequency which occurs when sound is reflected or transmitted from a ...

Renal vessel–assisted anastomosis improves the abdominal heart transplant model in rats without bilateral lower limb ischemia

open access: yesAnimal Models and Experimental Medicine, EarlyView.
A modified heterotopic heart transplantation (HTx) in rats was reported to improve the surgical success rate, in which the donor's vessels, the brachiocephalic trunk (BT) and the pulmonary artery (PA), were sutured to the recipient's left renal artery (RA) and left renal vein (RV).

Experimental methods for wind tunnel studies of seed dispersal by wind

open access: yesApplications in Plant Sciences, EarlyView.
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

Genome‐Wide DNA Methylation Study Reveals Specific Signatures in the Affected Arterial Tissue of Patients With Giant Cell Arteritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Giant cell arteritis (GCA) is a large‐vessel vasculitis, potentially causing complications such as blindness and strokes. This study aims to gain insights into the pathogenesis of GCA by identifying specific DNA methylation signatures in the arterial tissue of patients with this vasculitis. Methods DNA methylation profiling was analyzed in 79

Carotid artery disease screening : assessment of criteria [PDF]

open access: yes, 1996
The Department of Radiology at St. Luke’s Hospital has provided a screening service for stroke related disease since April 1991. This consisted of Duplex Ultrasound screening (DUS) for Extracranial Carotid Artery Disease (ECAD) followed by angiography or

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

open access: yesBMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Using a combination of superb microvascular imaging and other auxiliary ultrasound techniques to increase the accuracy of gray-scale ultrasound for breast masses

open access: yesBMC Cancer
Background Breast ultrasound is highly sensitive, but its specificity is not as high for detecting malignant lesions. Auxiliary modalities like elastography, Color and Power Doppler ultrasound are used as adjuncts to yield both a high sensitivity and ...
