Endothelial Dysfunction Linked to Ventricular Dysfunction in Children With Sickle Cell Disease, a 3D Speckle Tracking Study.

Background: Sickle Cell Disease (SCD) is not a hematologic disease that occurs in isolation; it results in multi-organ complications. There is growing evidence of vascular stiffness as its underlying cause. This study aimed to investigate the relationship between endothelial stiffness and LV dysfunction in SCD patients and to explore its pathophysiology, particularly regarding the depletion of vasodilators such as Nitric Oxide (NO).

Endoscopic ultrasound-guided biliary drainage for distal malignant biliary obstruction: a prospective 3-year multicenter Egyptian study.

Background/aim: Malignant biliary obstruction (MBO) is often diagnosed at late stages with mostly unresectable lesions. Recently, EUS-guided biliary drainage (EUS-BD) has gained wide acceptance and appears to be a feasible and safe backup option after ERCP failure in such patients. Herein, we aimed to represent a 3-year multi-center Egyptian experience in the application of this challenging procedure for distal MBO as a salvage technique after failed ERCP.

A new modality in targeted delivery of epirubicin for tumor theranosis based on PEGylated silver nanoparticles: Design, radiolabeling and bioevaluation.

This work highlights boosting the tumor targeting efficiency of epirubicin through loading on a new radionanosystem, based on the effective role of silver nanoparticles (AgNPs). Accordingly, PEGylated silver nanoparticles (PEG/AgNPs) were prepared in a size of 20.2 ± 0.

Crystal structure and Hirshfeld surface analysis of (±)-'-(2-hy-droxy-3-meth-oxy-benzyl-idene)-2-(4-iso-butyl-phen-yl)propionohydrazide.

The title mol-ecule, CHNO, adopts a V-shaped conformation and is chiral at the C atom with methyl group attached at the common cut of the edges of the V-conformation and crystallizes as a racemate. It also contains an intra-molecular O-H⋯N hydrogen bond. In the crystal, N-H⋯O hydrogen bonds form chains of mol-ecules extending along the -axis direction, together with normal van der Waals contacts.

An AI-Enabled Internet of Things Based Autism Care System for Improving Cognitive Ability of Children with Autism Spectrum Disorders.

Smart monitoring and assisted living systems for cognitive health assessment play a central role in assessment of individuals' health conditions. Autistic children suffer from some difficulties including social skills, repetitive behaviors, speech and nonverbal communication, and accommodating to the environment around them. Thus, dealing with autistic children is a serious public health problem as it is hard to determine what they feel with a lack of emotional cognitive ability.
