Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current

Escenarios de vulnerabilidad por ascenso del nivel del mar en la costa mexicana del Golfo de México y el Mar Caribe

open access: yesInvestigaciones Geográficas, 1999
Mediante la caracterización geomorfológica del litoral se identifican áreas vulnerables a las variaciones del nivel del mar. A partir de esta zonificación se estimaron las áreas de impacto por inundación sobre el nivel del mar a 1 y 2 m.

Synthesis of polyaniline/TiO2 nanocomposites: effects of acid and aniline concentrations on material properties and photocatalytic performance for sulfamethoxazole degradation

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND This work investigated the synthesis of TiO2‐P25/polyaniline (PANI) nanocomposites, denoted as PANI– TiO2, via chemical oxidative polymerization under different aniline:H+ molar ratios, and evaluated their performance in heterogeneous photocatalysis (HP).

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

open access: yesJournal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Diagnostic Accuracy of Shear Wave Elastography for the Assessment of Congestive Liver Disease in Patients With Structural Heart Disease

open access: yesJournal of Clinical Ultrasound, EarlyView.
Shear wave elastography demonstrated moderate diagnostic accuracy for detecting congestive liver disease in patients with structural heart disease. Increased liver stiffness was associated with echocardiographic markers of venous congestion, supporting the concept that elastography may serve as a noninvasive marker of cardiohepatic interaction ...

Morfodinámica del litoral caribe y amenazas naturales

open access: yesCuadernos de Geografía: Revista Colombiana de Geografía, 2001
La mayoría de los modelados de los litorales (formas y formaciones superficiales), se relacionan con los cambios del nivel del mar, a su vez ligados a los cambios climáticos del cuaternario.

Irritability in preschool children with attention‐deficit/hyperactivity disorder: Analysis of family environmental factors

open access: yesJCPP Advances, EarlyView.
Abstract Background Irritability affects one‐third of children and adolescents with attention‐deficit/hyperactivity disorder (ADHD) and is associated with negative outcomes. The family environment plays a prominent role in the child's development, and therefore on the risk for irritability, especially during the preschool period.
