Fast and efficient electrochemical thinning of ultra-large supported and free-standing MoS layers on gold surfaces.

Molybdenum disulfide (MoS) is a very promising layered material for electrical, optical, and electrochemical applications because of its unique and outstanding properties. To unlock its full potential, among different preparation routes, electrochemistry has gain interest due to its simple, fast, scalable and simple instrumentation. However, obtaining large-area monolayer MoS that will enable the fabrication of novel electronic and electrochemical devices is still challenging.

Graphene oxide-silver nanoparticle hybrid material: an integrated nanosafety study in zebrafish embryos.

This work reports an integrated nanosafety study including the synthesis and characterization of the graphene oxide-silver nanoparticle hybrid material (GO-AgNPs) and its nano-ecotoxicity evaluation in the zebrafish embryo model. The influences of natural organic matter (NOM) and a chorion embryo membrane were considered in this study, looking towards more environmentally realistic scenarios and standardized nanotoxicity testing. The nanohybrid was successfully synthesized using the NaBH aqueous method, and AgNPs (~ 5.

Radiolabelled nanohydroxyapatite with 99mTc: perspectives to nanoradiopharmaceuticals construction.

The use of nanoparticles is under intense investigation. The possible advantages proposed by these systems are very impressive and the results may be quite schemer. In this scenario, the association of nanoparticles with radioactive materials (radionuclide) may be the most important step since the discovery of radioactive for nuclear medicine and radiopharmacy, especially for cancer targeting and therapy.

[Periodontal condition and tooth loss in diabetic patients].

Introduction: Diabetes is a systemic disease which affects the metabolism of glucose,and it has been associated with the development of periodontal disease.

Objective: The periodontal condition and tooth loss was evaluated in diabetic subjects.

Materials And Methods: At the San Vicente de Paúl Hospital (Medellín, Colombia), 117 subjects with type 1 and 2 diabetes mellitus were examined.

Tooth and periodontal clinical attachment loss are associated with hyperglycemia in patients with diabetes.

Background: Periodontal disease has been associated with diabetes, but there is still controversy on the relationship between periodontal clinical parameters and glycemic control. The purpose of this study is to assess the relationship between blood glucose levels and clinical parameters of periodontal disease in individuals with diabetes.

Methods: A total of 65 individuals with diabetes and 81 individuals without diabetes were included in the study.
