The influence of organic solvents on estimates of genotoxicity and antigenotoxicity in the SOS chromotest

Genetics and Molecular Biology, 2012
In this work, the toxicity and genotoxicity of organic solvents (acetone, carbon tetrachloride, dichloromethane, dimethylsulfoxide, ethanol, ether and methanol) were studied using the SOS chromotest.

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, EarlyView.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.

Using Cu2+‐Centered Complexes as Glue: Two New Layered Polyoxotantalates Based on the Interconnection of the {Ta6O19} Moiety

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Layered structures of polyoxotantalates generated by different connection modes of the dimeric {(Cu(dien))2Cu(Ta6O19)2} unit. Applying the three different solutions [Cu(dien)]2+ in DMSO/H2O, acetonitrile, and [Ta6O19]6‐/H2O in a layering approach, the two new polyxotantalates [Cu(dien)]5{(Cu(dien)(H2O)2)Cu(Ta6O19)2}·DMSO·32 H2O (I) and K2[(Cu(dien))6 ...

Estudio cinético de la interconversión de Astilbina mediante espectroscopia de 1H-rmn [PDF]

Avances en Química, 2012
The interconversion kinetics of astilbin to a mixture of their respective diasteroisomers was studied by nuclear magnetic resonance spectroscopy using selective irradiation experiments (TOCSY) in dimethylsulfoxide. It is proposed a model which allowed

Aminophenoxycyclotriphosphazene cured epoxy resins and the composites, laminates, adhesives and structures thereof [PDF]

, 1977
Aminophenoxy cyclotriphosphazenes such as hexakis (4-aminophenoxy) cyclotriphosphazene and tris (4-aminophenoxy)-tris phenoxy cyclotriphosphazene are used as curing agents for epoxy resins.

Establishment of Human Formative Pluripotent Stem Cell‐Like Cells Exhibiting Amniotic Differentiation Potentials

Cell Proliferation, EarlyView.
The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

The FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

Influence of the post‐processing protocol on a biocompatible 3D‐printed resin

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the cytotoxicity of a biocompatible 3D‐printed resin material for occlusal devices after post‐processing with two different high‐intensity UV‐polymerization devices and two rinsing solvents, in the presence of human gingival fibroblasts (HGFs).

Histopathological investigation of wound healing activities of Lucilia sericata Larva and Achillea sintenisii extract combinations in diabetic rat wound model

Medical and Veterinary Entomology, EarlyView.
Lucilia sericata larvae secrete bioactive compounds that promote wound debridement and antimicrobial defence in chronic tissue injuries. Achillea sintenisii extract offers phytotherapeutic support, enhancing healing through anti‐inflammatory and regenerative properties. Diabetic Wistar rats were treated topically with Furacin®, larval secretions, plant
