Amino-Fe 3 O 4 -functionalized graphene oxide as a novel adsorbent of Methylene Blue: kinetics, equilibrium, and recyclability aspects

Abstract

Graphene oxide (GO) was synthetized from graphite oxidation via the modified Hummers method. Afterwards, the GO was functionalized with diethylenetriamine (DETA) and FeCl3 to obtain the novel amino-iron oxide functionalized graphene (GO-NH2-Fe3O4). FTIR, XRD, SEM with EDX, and Raman spectroscopy were performed to characterize both GO and GO-NH2-Fe3O4. The GO-NH2-Fe3O4 was then evaluated as adsorbent of the cationic dye Methylene Blue (MB); analysis of the point of zero net charge (pHPZC) and pH effect showed that the GO-NH2-Fe3O4 pHPZC was 8.2; hence, the MB adsorption was higher at pH 12.0. Adsorption kinetics studies indicated that the system reached the equilibrium state after 5 min, with adsorption capacity at equilibrium (qe) and kinetic constant (kS) of 966.39 mg g−1 and 3.17∙10−2 g mg−1 min−1, respectively; moreover, the pseudo-second-order model was better fitted to the experimental data. Equilibrium studies showed maximum adsorption capacity of 1047.81 mg g−1; furthermore, Langmuir isotherm better fitted the adsorption. Recycling experiments showed that the GO-NH2-Fe3O4 maintained the MB removal rate above 95% after 10 cycles. All the results showed sorbent high adsorption capacity and outstanding regeneration capability and evidenced the employment of novel GO-NH2-Fe3O4 as a profitable adsorbent of textile dyes.



Building a Cardio-Onco-Hematology Program

Abstract

Purpose of Review

This review aims to outline the general principles of how to build a cardio-onco-hematology clinic, acknowledging that there are diverse practices ranging from private community settings to academic hospitals and each practice environment has to build its own program.

Recent Findings

The refinement of regimens and introduction of molecularly directed therapies have substantially increased survival rates for patients with cancer. In fact, a number of previous imminently fatal malignant disease processes have been turned into chronic diseases, such that patients now live with certain incurable cancers as they do, for instance, with rheumatoid arthritis. Improved cure rates and longer survivals have raised side effects of cancer treatments to a completely new level of significance. Cardiovascular toxicities are of particular concern given their impact on morbidity and mortality. In most extreme cases, patients might be cured from cancer but remain debilitated or die prematurely because of cardiovascular disease. Furthermore, not an insignificant proportion of cancer patients start cancer therapy with cardiovascular risk factors and diseases at baseline. With the aging of the population, this "joint venture" is only expected to increase with important implications for the management of cancer patients.

Summary

Given the need for familiarity with both, cancer and cardiovascular diseases and their ever-evolving start-of-the-art therapy and interaction potential, specialized efforts have been invoked, which may collectively be termed "onco-cardiology," "cardio-oncology," or "cardio-onco-hematology." Herein, we provide recommendations for the creation and optimization of any such programmatic efforts.

Ethyl 2,4-dicarboethoxy pantothenate, a derivative of pantothenic acid, prevents cellular damage initiated by environmental pollutants through Nrf2 activation

Recently, there has been increasing concern about the influence of environmental pollutants, such as particulate matter 2.5 (PM2.5), diesel fuel exhaust, cigarette smoke, ozone (O3), heavy metals and halogenated hydrocarbons, on public health. Therefore, the influence of environmental pollution on public health has been actively studied focusing on the lungs and the cardiovascular system because of the risk of inhalation. The effects of environmental pollution on cellular physiology have been clarified as follows: Polycyclic aromatic hydrocarbons (PAHs), which are the main components of pollutants, induce inflammation by activating the aryl hydrocarbon receptor (AHR) signaling pathway [1–3].

ABSTRACT
Background

Chronic pulmonary aspergillosis (CPA) and allergic bronchopulmonary aspergillosis (ABPA) are presumed to represent two distinct manifestations of Aspergillus species in the lung.

Objective

To investigate any possible overlap of the immunological tests used for diagnosing ABPA in proven cases of CPA.

Methods

In consecutive subjects with CPA, we calculated the proportion of subjects who tested positive for all the immunological investigations used to diagnose ABPA (A.fumigatus-specific IgE >0.35 kUA/L, total IgE ≥500 IU/mL and eosinophil count ≥500 cells/μL) or obligatory criteria (A.fumigatus-specific IgE >0.35 kUA/L and total IgE ≥500 IU/mL).

Results

269 subjects (53.5% males) of CPA with mean (SD) age of 44.3 (14.7) years were enrolled. The most common underlying disease was previously treated pulmonary tuberculosis (n=230, 85.5%). Ninety-three (34.6%) subjects had total IgE ≥500 IU/mL, while A.fumigatus-specific IgE >0.35 kUA/L was seen in 112 (41.6%) subjects. Thirteen (4.8%) subjects met all the immunological criteria for ABPA, while 59 (21.9%) subjects met the obligatory criteria. Subjects meeting the obligatory criteria had significantly higher eosinophil count (p=<0.0001), greater immediate cutaneous reactivity to Aspergillus antigen (CPA-others vs. obligatory criteria, 9.8±13.9 vs. 13.9±14.9 mm, p value=0.048), higher A.fumigatus-specific IgG (99.3±61.9 vs. 122±66.6 mgA/L, p=0.015) and greater number of fungal balls (0.9±0.7 [range, 0-3] vs. 1.1±0.9 [range, 0-4], p=0.026) compared to those without.

Conclusions

About 5% of subjects with CPA fulfilled all the immunological criteria used for diagnosing ABPA while 22% met the obligatory criteria for ABPA. Whether these patients would require a different management protocol requires further investigation.

Résumé

Le choix dans le type d'implant que le chirurgien utilise se fait souvent sur des arguments médico-commerciaux, des croyances, et du ressenti subjectif plutôt que sur de réels arguments scientifiques. Nous avons rarement l'occasion de comparer de manières objectives les fabricants entre eux. Ainsi notre objectif ici a été simplement de regrouper sur un même support l'ensemble des spécificités des différents acteurs du marché français. Ceci aussi bien sur le plan technique que sur le plan de l'offre commerciale.

Summary

The choice of an implant by a plastic surgeon is often based on marketing arguments, beliefs, and subjective reasons more than real high level evidence basis. Furthermore, we rarely compare manufacturers with each other objectively. Therefore our aim was to put together information coming from the different companies available in France in a single article.

Resumen
Introducción

La urticaria solar (US) es una fotodermatosis infrecuente. Los antihistamínicos constituyen la primera línea de tratamiento, incluyéndose en segunda línea la inducción de fototolerancia mediante fototerapia con ultravioleta.

Objetivos

Describir y evaluar la eficacia de un protocolo de desensibilización, con UVB de banda estrecha (UVB-BE) en pacientes con US.

Material y métodos

Estudio retrospectivo de pacientes diagnosticados de US con espectro de acción en UVA, luz visible (LV) o ambas, que habían realizado fototerapia con UVB-BE para inducir fototolerancia. Se realizan cursos cortos (menos de 20 sesiones, 3 por semana) durante la primavera, con dosis inicial determinada por el fototipo. Se recogen resultados del Skindex-29 antes del tratamiento y después del verano, y un cuestionario no validado de efectividad terapéutica después del verano para valorar actividad de la enfermedad y grado de satisfacción.

Resultados

Se incluyen 8 pacientes con espectro de acción: 50% LV y 50% UVA más luz visible. Se realizaron 17 cursos anuales (1-6 cursos por paciente), de 11 a 20 sesiones. La dosis media de UVB-BE por curso fue 7,45 J/cm2. Ningún paciente presentó brotes o efectos adversos durante el tratamiento. La respuesta fue satisfactoria en 6 pacientes. En el 78,6% de los tratamientos la mejoría en el Skindex-29 global fue superior al 20%. La mejoría en las subescalas sintomática y funcional fue superior al 20% en el 71% y el 64% respectivamente.

Conclusión

La inducción de fototolerancia con UVB-BE en la US es un procedimiento seguro y efectivo en un elevado porcentaje de pacientes.

Abstract
Introduction

Solar urticaria is an uncommon photodermatosis. First-line treatment is with antihistamines; second-line treatment includes induction of light tolerance using UV phototherapy.

Objectives

We aimed to describe and evaluate the effectiveness of a desensitization protocol with narrowband UV-B in patients with solar urticaria.

Material and methods

We performed a retrospective study of patients with solar urticaria with an action spectrum in the UV-A range, the visible light range, or both who had received therapy with narrowband UV-B for induction of light tolerance. Short courses of treatment were administered (< 20 sessions, 3 per week) during spring. The initial dose was determined according to the skin type. The Skindex-29 was administered before treatment and after summer; a nonvalidated questionnaire was also administered after summer to evaluate disease activity and satisfaction with treatment.

Results

We included 8 patients with an action spectrum (4 with visible light and 4 with UVA plus visible light). Seventeen courses (1-6 per patient) were administered per year. The number of sessions per year ranged from 11 to 20. The mean dose of narrowband UV-B per course was 7.45 J/cm2. No patients experienced flares or adverse effects during treatment. The response was satisfactory in 6 patients. The improvement in the overall Skindex-29 score was greater than 20% in 78.6% of cases. The improvement in the function and symptoms subscales was over 20% in 71% and 64% of cases, respectively.

Conclusion

Induction of light tolerance with narrowband UV-B in solar urticaria is safe and effective in a high percentage of patients.
