Silver nanoparticles: green synthesis and their antimicrobial activities.
This review presents an overview of silver nanoparticles (Ag NPs) preparation by green synthesis approaches that have advantages over conventional methods involving chemical agents associated with
Aquatic arsenic: toxicity, speciation, transformations, and remediation.
The number of different arsenic species found in environmental samples and an understanding of the transformations between arsenic species has increased over the past few decades as a result of new and refined analytical methods.
Silver colloid nanoparticles: synthesis, characterization, and their antibacterial activity.
The reduction of [Ag(NH(3))(2)](+) by maltose produced silver particles with a narrow size distribution with an average size of 25 nm, which showed high antimicrobial and bactericidal activity against Gram-positive and Gram-negative bacteria, including highly multiresistant strains such as methicillin-resistant Staphylococcus aureus.
Potassium ferrate(VI): an environmentally friendly oxidant
Abstract The iron(VI) derivative, potassium ferrate(VI) (Fe(VI)) has properties such as high stability, oxidizing power, selectivity, and a non-toxic by-product Fe(III), that make potassium
A Meta-Analysis of the Yield of Capsule Endoscopy Compared to Other Diagnostic Modalities in Patients with Non-Stricturing Small Bowel Crohn's Disease
In study populations, CE is superior to all other modalities for diagnosing non-stricturing small bowel CD, with a number needed to test to yield one additional diagnosis of CD over small bowel barium radiography and NNT = 7 over colonoscopy with ileoscopy.
A Meta-Analysis of the Yield of Capsule Endoscopy Compared to Other Diagnostic Modalities in Patients with Obscure Gastrointestinal Bleeding
CE is superior to push enteroscopy and small bowel barium radiography for diagnosing clinically significant small bowel pathology in patients with OGIB, according to a recursive literature search of prospective studies comparing the yield of CE to other modalities in patientswith OGIB.
Adsorption of arsenate and arsenite on titanium dioxide suspensions.
The electrostatic factors between surface charge of TiO2 particles and arsenic species were used to explain adsorption behavior of As(V) and As(III) at different pH.
Radiofrequency ablation in Barrett's esophagus with dysplasia.
In patients with dysplastic Barrett's esophagus, radiofrequency ablation was associated with a high rate of complete eradication of both dysplasia and intestinal metaplasia, and a reduced risk of disease progression.
A Single-Center Experience of 260 Consecutive Patients Undergoing Capsule Endoscopy for Obscure Gastrointestinal Bleeding
The yield of clinically important findings on CE is 53% and is greater in patients with obscure-overt than obscure-occult GI bleeding, and compared with pre-CE, patients had clinical improvement post-CE in medical interventions for OGIB.
Double-balloon enteroscopy and capsule endoscopy have comparable diagnostic yield in small-bowel disease: a meta-analysis.
CE and DBE have comparable diagnostic yield in SB disease, including obscure gastrointestinal bleeding, and should be the initial diagnostic test because of its noninvasive quality, tolerance, ability to view the entire SB, and for determining the initial route of DBE.
