Impacto de la variación de la altura sobre el nivel del mar en los parámetros clínicos y hemodinámicos en hipertensión arterial pulmonar: a propósito de un caso

Archivos Peruanos de Cardiología y Cirugía Cardiovascular, 2021
El seguimiento clínico de la hipertensión arterial pulmonar en nuestro país, en el que los pacientes proceden de distintas altitudes sobre el nivel del mar, nos obliga a descartar hipertensión pulmonar en relación con la exposición crónica a grandes ...

Análisis de tendencias del nivel del mar para la costa central del golfo de México 1999-2018

Investigaciones Geográficas, 2022
Hay consenso científico sobre un aumento en el nivel medio del mar global de alrededor de 0.20 metros durante el periodo 1901-2018 (IPCC, 2021). Este es global, pero no homogéneo, por lo que resultan relevantes los estudios a escalas menores.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Nuclear Pore Mechanotransduction in Oncology: A Structural Axis of Vulnerability for Targeted Intervention

Advanced Materials, EarlyView.
Cancer‐associated NPC remodeling creates a high‐flux, low‐stringency nuclear state that supports malignant adaptation but increases mechanical fragility. Targeting the FG‐barrier or NPC scaffold may drive mechanostat failure, envelope rupture, DNA damage, and loss of nuclear integrity.

NIR I‐to‐NIR I Time‐Gated Luminescence Detection From Tm3+‐Doped Gd3TaO7 for Deep Tissue Imaging

Advanced Optical Materials, EarlyView.
A new generation of optical imaging (OI) using temporal resolution, exploring a NIR I‐to‐NIR I biological window emission by a Phonon Assisted Conversion (PAC) system singly doped with Tm3+ ions. Although still in early development, this approach opens new directions for designing optimized fluorophores to enhance bioimaging performance.

Autoantibodies to Extracellular Erythrocyte Band 3 Epitopes Are Associated With Anemia in Plasmodium vivax Infection

American Journal of Hematology, EarlyView.
ABSTRACT Plasmodium vivax‐associated anemia is a multifactorial clinical outcome, in which the destruction of uninfected red blood cells (uRBCs) plays a major role in disease development and severity. Here, we identified autoantibody targets within the extracellular loops of Band 3 (B3), a major erythrocyte transmembrane protein.

Genetic Variation in ADHD‐Related Risk Genes in an Indigenous Population of the Amazon

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Attention‐Deficit/Hyperactivity Disorder (ADHD) is a highly heritable neurodevelopmental disorder; however, its genetic architecture remains poorly explored in Indigenous populations. This study aimed to analyze and characterize genetic variation in 11 genes (ADGRL3, CDH8, DCC, DUSP6, FOXP1, FOXP2, MEF2C, PCDH7, SEMA6D, SORCS3, and ST3GAL3 ...
