High photothermal conversion efficiency of RF sputtered TiO Magneli phase thin films and its linear correlation with light absorption capacity.

RF-sputtering is used to deposit TiO-Magneli-phase films onto various substrates at deposition temperatures (T) ranging from 25 to 650 °C. Not only the structural, but also electrical conductivity, optical absorbance and photothermal properties of the TiO films are shown to change significantly with T. A T of 500 °C is pointed out as the optimal temperature that yields highly-crystalized pure-TiO-Magneli phase with a densely-packed morphology and a conductivity as high as 740 S/cm.

Sperm Functional Status: A Multiparametric Assessment of the Fertilizing Potential of Bovine Sperm.

Sperm viability is routinely assessed for the quality control of cryopreserved bovine sperm batches but is not usually conclusive regarding their fertilizing potential. In this study, we investigated the fertility predictive value of bull sperm viability in combination with DNA integrity or the functional status of viable sperm. In addition to sperm viability, we flow cytometrically assessed the percentage of sperm with high DNA fragmentation index (%DFI) and the fraction of viable sperm with low intracellular Ca content and functional mitochondria using the Sperm Chromatin Structure Assay and a five-color staining panel in 791 and 733 cryopreserved batches with non-return rate (NRR) records after ≥100 first services, respectively.

Methods: Data from consecutive patients undergoing ICD implantation were retrospectively analyzed.

High Shear Stress Reduces ERG Causing Endothelial-Mesenchymal Transition and Pulmonary Arterial Hypertension.

Background: Computational modeling indicated that pathological high shear stress (HSS; 100 dyn/cm) is generated in pulmonary arteries (PAs; 100-500 µm) in congenital heart defects causing PA hypertension (PAH) and in idiopathic PAH with occlusive vascular remodeling. Endothelial-to-mesenchymal transition (EndMT) is a feature of PAH. We hypothesize that HSS induces EndMT, contributing to the initiation and progression of PAH.

Unveiling the role of sintering temperatures in the physical properties of Cu-Mg ferrite nanoparticles for photocatalytic application.

This research presents an explicit analysis of the effects of sintering temperature (T) on the structural, morphological, magnetic, and optical properties of CuMgFeO nanoferrites synthesized via the sol-gel method. To accomplish it, Cu-Mg ferrite NPs were sintered at temperatures ranging from 300 to 800 °C in increments of 100 with a constant holding duration of 5 h. Thermogravimetric analysis was used to observe the degradation of organic components and the thermally stable zone of the material.

Worldwide comparison of carbon stocks and fluxes between native and non-native forests.

Climate change is one of the main challenges that human societies are currently facing. Given that forests represent major natural carbon sinks in terrestrial ecosystems, administrations worldwide are launching broad-scale programs to promote forests, including stands of non-native trees. Yet, non-native trees may have profound impacts on the functions and services of forest ecosystems, including the carbon cycle, as they may differ widely from native trees in structural and functional characteristics.

Conditioned serum-free culture medium accomplishes adhesion and proliferation of bovine myogenic cells on uncoated dishes.

To establish a sustainable cultured meat technology, a low-cost culture medium must be developed without expensive biological materials such as serum and coating substances. However, even adhering bovine myogenic cells to uncoated culture dishes in the serum-free medium is challenging. We found that serum-free culture medium conditioned by HepG2 and NIH/3T3 cells not only accomplished the cell adhesion on uncoated culture dishes (the serum-containing medium : the serum-free medium : the conditioned medium = 6722 ± 1500 : 2210 ± 319 : 5985 ± 1558 cells/cm), but also induced proliferation comparable to that observed in a serum-containing medium (the serum-containing medium : the serum-free medium : the conditioned medium = 10,050 ± 2814 : 2200 ± 707 : 8998 ± 3890 cells/cm).

Synergistic Potential of Argentatins A and B to Improve 5-Fluorouracil Cytotoxicity in Colorectal Cancer Cell Models.

Colorectal cancer is the third most commonly diagnosed cancer worldwide and the second most common cause of cancer-related death in both men and women. Although a number of treatments are available to combat this malignancy, the antimetabolite 5-fluorouracil has been the cornerstone of therapy since its synthesis in the 1950s. Unfortunately, the prolonged use of 5-fluorouracil can lead to chemoresistance, which has prompted research into combination regimens to improve efficacy and quality of life and reduce resistance.

Child Neurology: Neurophysiologic and Anatomical Correlates in Startle Epilepsy: A Comprehensive SEEG Investigation for Successful Resective Surgery.

Startle epilepsy, characterized by startle-provoked epileptic seizures, was historically recognized as one of the reflex epilepsies but currently lacks classification as a specific epileptic syndrome because of insufficient characterization. This study presents an institutional experience and review of relevant literature focusing on the neurophysiologic and anatomical aspects of startle epilepsy. We describe a pediatric patient with an underlying structural etiology of left frontal encephalomalacia who continued to experience disabling seizures despite multiple antiseizure medications and previous palliative surgery.

Use of Right Ventricular Free-Wall Strain in a Multivariable Estimate of Right Ventricular-Arterial Coupling in Pediatric Pulmonary Arterial Hypertension.

Background: Right ventricular-arterial coupling (RVAC) describes the relationship between right ventricular contractility and pulmonary vascular afterload. Noninvasive surrogates for RVAC using echocardiographic estimates of right ventricular function, such as tricuspid annular plane systolic excursion (TAPSE), have been shown to correlate with invasively measured RVAC and predict clinical outcomes in pediatric pulmonary arterial hypertension. However, given the limitations of TAPSE at accurately estimating right ventricular function in children, we hypothesized that a multivariable estimate of RVAC using right ventricular free-wall longitudinal strain (RVFW-LS) may perform better than those utilizing TAPSE at predicting clinical outcomes.

Oxidation Behavior of Aluminide Coatings on Cobalt-Based Superalloys by a Vapor Phase Aluminizing Process.

In this work, the oxidation behavior of an aluminide coating at 900, 1000, and 1100 °C was investigated.
