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

Chemistry

January 2025

Friedrich-Alexander-Universität Erlangen-Nürnberg: Friedrich-Alexander-Universitat Erlangen-Nurnberg, Department of Materials Science and Engineering, Institute of Materials for Electronics and Energy Technology (i-MEET), Martensstraße 7, 91058, Erlangen, GERMANY.

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.

Hidden infections and late diagnoses are currently the main challenges of the HIV pandemic. Emergency departments (EDs) are one of the health care system's key resources addressing these challenges. In 2020, the Spanish Society of Emergency Medicine (SEMES) published recommendations for ordering HIV serology testing for patients with certain health conditions, and in 2021 SEMES launched the "Leave Your Mark" (Deja tu Huella - DTH) program to facilitate implementing the recommendations during emergency care.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).

Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.

Impairment of gut barrier integrity is associated with the pathogenesis of gastrointestinal diseases, including inflammatory bowel disease, colorectal cancer, and coeliac disease. While many aspects of diet have been linked to improved barrier function, (poly)phenols, a broad group of bioactive phytochemicals, are of potential interest. The (poly)phenolic sub-class, flavan-3-ols, have been investigated in some detail owing to their abundance in commonly consumed foods, including grapes, tea, apples, cocoa, berries, and nuts.

This study examines the behavior of the Casson nanofluid bioconvection flow around a spinning disc under various influences, including gyrotactic microorganisms, multiple slips, and thermal radiation. Notably, it accounts for the reversible nature of the flow and incorporates the esterification process. The aim of this study is to investigate the influence of reversible chemical reactions on the flow behavior of a Casson nanofluid in the presence of bioconvective microorganisms over a spinning disc.

The hypothalamus integrates peripheral signals and modulates food intake and energy expenditure by regulating the metabolic function of peripheral tissues, including the liver and adipose tissue. In a previous study, we demonstrated that s-resistin, an intracellular resistin isoform highly expressed in the hypothalamus and upregulated during aging, is important in the central control of energy homeostasis, affecting mainly the peripheral response to insulin by still unknown mechanisms. Herein, using an intracerebroventricular injection of a specific lentiviral RNAi against s-resistin, we assessed, in the Wistar rat, the effects of central s-resistin downregulation on the expression and phosphorylation levels of intermediates involved in insulin signaling and the inflammatory response in epididymal white adipose tissue (eWAT) and liver.

Influence of Fatigue on the Modification of Biomechanical Parameters in Endurance Running: A Systematic Review.

Int J Exerc Sci

December 2024

Research Group in Health, Physical Activity, and Sports Technology (Health-Tech), Faculty of Education, University of Alicante, San Vicente del Raspeig, SPAIN.

Fatigue accumulated during the practice of endurance running can be understood as the decrease in sports performance caused by physical exertion. Since fatigue can manifest itself in multiple ways, its influence is difficult to understand, and many authors propose different studies with the aim of obtaining firm conclusions. Thus, the aim of this systematic review was to analyze the effect of fatigue on the modification of biomechanical parameters to mitigate adverse effects and optimize positive adaptations to training.

Background And Objectives: In the era of precision medicine, genetic test results have become increasingly relevant in the care of patients with Parkinson disease (PD). While large research consortia are performing widespread research genetic testing to accelerate discoveries, debate continues about whether, and to what extent, the results should be returned to patients. Ethically, it is imperative to keep participants informed, especially when findings are potentially actionable.

Thermoplastic polymers provide a versatile platform to mimic various aspects of physiological extracellular matrix properties such as chemical composition, stiffness, and topography for use in cell and tissue engineering applications. In this review, we provide a brief overview of the most promising thermoplastic polymers, and in particular the thermoplastic polyesters, such as poly(lactic acid), poly(glycolic acid), and polycaprolactone, and the thermoplastic elastomers, such as polyurethanes, polyhydroxyalkanoates, and poly(butyl cyanoacrylate). A particular focus has been made on the synthesis processes, the processability and the biocompatibility.

Paediatric cancers, although rare, are the leading cause of disease-related mortality in European children above one year. A key pillar of the European Health Union, Europe's Beating Cancer Plan (EBCP) puts a spotlight on childhood cancer. National Cancer Control Plans (NCCPs) have a key role but did not address childhood cancers sufficiently previously.

Can we talk about ionic bonds in molecules? Yes, just as we do for covalent bonds.

Phys Chem Chem Phys

January 2025

Dpto. Química Física y Analítica, Univ. Oviedo, C/Julián Clavería 8, 33006 Oviedo, Spain.

A claim that ionic bonds exist only in ionic solids is critically analyzed by focusing on the controversial LiH molecule, classified as covalent by non-orthogonal valence bond supporters, polar-covalent by molecular orbital advocates, and ionic by real-space proponents. Using orbital invariant techniques we show that LiH can be regarded ionic in the same manner that dihydrogen is considered covalent.

Centro de Energia Nuclear na Agricultura, Universidade de São Paulo (USP), Piracicaba, São Paulo, Brazil.

Moniliophthora perniciosa is the causal agent of the witches' broom disease of cacao (Theobroma cacao), and it can infect the tomato (Solanum lycopersicum) 'Micro-Tom' (MT) cultivar. Typical symptoms of infection are stem swelling and axillary shoot outgrowth, whereas reduction in root biomass is another side effect. Using infected MT, we investigated whether impaired root growth derives from hormonal imbalance or sink competition.

The 'Viroporin' family comprises a number of mostly small-sized, integral membrane proteins encoded by animal and plant viruses. Despite their sequence and structural diversity, viroporins share a common functional trend: their capacity to assemble transmembrane channels during the replication cycle of the virus. Their selectivity spectrum ranges from low-pH-activated, unidirectional proton transporters, to size-limited permeating pores allowing passive diffusion of metabolites.
