Comparative Study of Iminodibenzyl and Diphenylamine Derivatives as Hole Transport Materials in Inverted Perovskite Solar Cells.

Perovskite solar cells (PSCs) have recently achieved over 26% power conversion efficiency, challenging the dominance of silicon-based alternatives. This progress is significantly driven by innovations in hole transport materials (HTMs), which notably influence the efficiency and stability of PSCs. However, conventional organic HTMs like PTAA, although highly efficient, suffer from thermal degradation, moisture ingress, and high cost.

Mechanical Circulatory Support With Impella in High-Risk Patients With Chronic Total Occlusion and Complex Multivessel Disease.

Background: The therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.

Aims: The aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.

Methods: Retrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023.

[Blood pressure patterns in pressurometry and their ralationship with cardiovascular events in follow-up].

IntroducciÓn: Nuestro objetivo fue determinar en una cohorte de pacientes de un hospital de la ciudad de Buenos Aires, cómo fue la distribución de ritmo circadiano y el impacto según el tipo de comportamiento circadiano en la tasa de eventos cardiovasculares en el seguimiento. Material y métodos: Estudio de cohorte retrospectiva que incluyó pacientes adultos que se realizaron una presurometría ambulatoria en un hospital de la ciudad de Buenos Aires, incorporados a un registro propio entre marzo de 2017 y julio de 2020, con seguimiento de hasta 36 meses de la presurometría índice.

Resultados: De 522 sujetos, se incluyeron 494 en el análisis final.

Immigrant Health and Early-Onset Colorectal Cancer Disparities: Results From the Spanish Early-Onset Colorectal Cancer Consortium.

Purpose: To better understand immigration disparities among a Spanish Early-Onset Colorectal Cancer (SECOC) subset, according to the country of origin.

Patients And Methods: We selected 250 consecutive participants from the SECOC consortium. Data on baseline patient and tumor characteristics, family history of colorectal cancer (CRC), and follow-up were collected.

Exploring the effects of ageing on instrumental and sensory characteristics of meat from Lidia breed females: A comparative study of two commercial types.

The aim of this study was to assess the influence of ageing on instrumental and sensory qualities in Longissimus thoracis et lumborum (LTL) from heifers (n = 200) and cows (n = 100) of Lidia breed. The animals were slaughtered as heifers (24-48 months) or cull cows (> 48 months). For instrumental analysis, pars Thoracis aged at 7, 14 and 28 days was used; for sensory analysis, pars Lumborum aged at 14 and 28 days was evaluated.
