Theoretical-experimental correlation of magnetic behavior in diluted magnetic TiO2 nanotubes for memristive type applications

Heiddy P. Quiroz · Donny Barcenas · Daniel E. Nuñez · Jorge A. Calderón · y 5 más

The system consists of Co diluted in TiO2 nanotubes obtained by electrochemical anodization process over Co/Ti foils, with NH4F, distilled water, and ethylene glycol. Cobalt was deposited on the Ti foils (99.99% purity) via DC magnetron sputtering at room temperature. The anodization process establishes the percentage...

VALOR PREDICTIVO DEL VOLUMEN ADENOIDEO MEDIDO POR NASOFIBROSCOPIA VERSUS RADIOGRAFÍA LATERAL DE CAVUM EN LA SEVERIDAD CLÍNICA DE LA APNEA OBSTRUCTIVA DEL SUEÑO PEDIÁTRICA.

Vanessa Alexandra Vizuete Cunalata · Charbel Kamil Faizal Gómez · Angie Alexandra Calderon Peña

Introducción: La apnea obstructiva del sueño (AOS) en la población pediátrica constituye un problema de salud pública con prevalencia estimada entre el 1% y el 5%. La hipertrofia adenoidea representa la causa anatómica más frecuente de obstrucción de la vía aérea superior en niños. La evaluación precisa del volumen ade...

The potential energy surface, thermochemistry, and cooperative hydrogen bonding in the water octamer

Ana Arango · Andy D. Zapata-Escobar · Santiago Gómez · Juliana Murillo-López · y 1 más

The potential energy surface of the water octamer was explored through an extensive stochastic search, followed by MP2/6–311++G(d, p) and DLPNO–CCSD(T) refinement, yielding hundreds of structures grouped into seventy-seven distinct geometrical motifs. These structures were classified according to the topology of the hy...

Photobiomodulation With 976 nm Diode Laser Enhances Osteoblastic Differentiation of Saos‐2 Cells Cultured on Collagen Membranes

Escobar Lina M. · Bendahan Zita · Pinzón Paula · Grajales Marggie · y 1 más

ABSTRACT Objective Laser photobiomodulation (PBM) influences cellular proliferation, morphology, and differentiation. Collagen membranes provide a bioactive scaffold that supports osteoblastic behavior; however, the effects of PBM on preosteoblastic Saos‐2 cells cultured on these membranes remain unclear. This study ai...

Intraluminal Hair Identified During Laparoscopic Appendectomy for Perforated Appendicitis in a Child

Urías Hernandez Lopez · Pastor Thomas Olivares · Jessica Olivera Herrera · Angelica Leal Caicedo · y 2 más

ABSTRACT Intraluminal foreign bodies, including hair, have been described in association with appendicitis, sometimes in complicated forms with perforation. It has been suggested that they may contribute to the inflammatory process through luminal obstruction and subsequent progression of inflammation. We present the c...

Multiple Confabulations Found in Bioinformatics Tasks Carried Out by Several Free Large Language Models

Diego A. Forero

Bioinformatics is one of the main areas in the health sciences with great potential for the application of Large Language Models (LLMs), as it mainly involves computational analysis of results derived from experimental and high-throughput analysis of human, animal, and cellular models. Testing available general-purpose...

Non-pharmacological rehabilitation strategies for pulmonary and physical recovery in ICU survivors after COVID-19: A systematic review

Yimy F. Medina · Eliana Isabel Rodríguez Grande · Javier Leonardo Galindo · Olga Cecilia Vargas Pinilla · y 2 más

Background Survivors of severe COVID-19 requiring intensive care frequently experience persistent pulmonary and functional impairment consistent with post–critical illness sequelae. The effectiveness of non-pharmacological rehabilitation in this severity-specific subgroup remains uncertain. Methods A systematic review...

Management of acute brain injury in pregnant patients what is different?

Daniel Agustin Godoy · Edoardo Picetti · Juan Antonio Llompart-Pou

Purpose of review To establish the anatomical and physiological basis for understanding the differences in the evaluation, diagnosis, and management of pregnant women with acute brain injury (ABI). Recent findings Underline the absence of specific guidelines and the limited available literature, demonstrating marked va...

Natural Compounds as Epimodulators in Epithelial Ovarian Cancer

Mélida del Rosario Lizarazo-Taborda · Julio César Villegas-Pineda · Holver Parada · Fabian Galvis · y 1 más

Epithelial ovarian carcinoma (EOC) is the most common type of ovarian cancer and represents the most lethal gynecologic neoplasm. EOC is usually diagnosed at late stages due to its nonspecific signs and symptoms. Although significant clinical advances have been made in other types of malignancies, EOC remains a disease...
