Removal of toxic hexavalent chromium graphene oxide nanoparticles: study of kinetics, isotherms, and thermodynamics.

In this study, graphene oxide (GO) was prepared by the Hummers' method from graphite material. The adsorption potential of GO-200 nm for the removal of Cr(vi) ions was investigated. Fourier transform infrared (FTIR) spectroscopy was used to analyze Cr(vi) before and after adsorption.

Evaluating Study Approach of Dental Students in Palestine using a Study Process Questionnaire: A Cross-Sectional Study.

Background: Learning approach strategies are an important factor to obtain knowledge in any professional course. Surface approach learning and deep approach learning are two main types of learning strategies.

Aim: The aim of present study was to evaluate the study approach strategies of dental students in Palestine.

Fragmentation of Different Calcification Growth Patterns in Bicuspid Valves During Balloon Valvuloplasty Procedure.

This study focuses on the calcification development and routes of type-1 bicuspid aortic valves based on CT scans and the effect of the unique geometrical shapes of calcium deposits on their fragmentation under balloon valvuloplasty procedures. Towards this goal, the novel Reverse Calcification Technique (RCT), which can predict the calcification progression leading to the current state based on CT scans, is utilized for n = 26 bicuspid aortic valves patients. Two main calcification patterns of type-1 bicuspid aortic valves were identified; asymmetric and symmetric with either partial or full arcs and circles.

Common FTO rs9939609 variant and risk of type 2 diabetes in Palestine.

Background: Genetic and environmental factors play a crucial role in the development of type 2 diabetes mellitus (T2DM) and obesity. This study aimed to investigate the association of the fat-mass and obesity-associated gene (FTO) rs9939609 variant with T2DM and body mass index (BMI) among Palestinian population.

Methods: A total of 399 subjects were recruited, of whom 281 were type 2 diabetic patients and 118 normoglycemic subjects.
