As a highly stable bandgap semiconductor, antimonene is an intriguing two-dimensional (2D) material in optoelectronics. However, its short layer distance and strong binding energy make it challenging to prepare high-quality large 2D antimonene; therefore, its predicted tunable bandgap has not been experimentally confirmed. In this work, we used a novel and simple approach to prepare smooth and large 2D antimonene with uniform layers through a pregrinding and subsequent sonication-assisted liquid-phase exfoliation process...

BACKGROUND: Exercise-induced bronchoconstriction (EIB) is diagnosed via exercise challenge on a treadmill. However, such testing requires complex equipment and sufficient healthcare resources. The fraction of exhaled nitric oxide (FeNO) test and mannitol bronchial provocation test (BPT) may serve as a surrogate of exercise testing. METHODS: We compared the diagnostic utilities of the FeNO test and mannitol BPT in predicting EIB in asthmatic children. We retrospectively analysed data from 60 asthmatic children aged 6-16 years...

Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RADseq on a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus, covering allopatry and sympatry...

The United States permits foreign nationals to apply for asylum if they have experienced persecution or have a fear of future persecution. In order to meet the criteria for persecution, the harm inflicted upon the asylum seeker does not need to be or have been physical and can include psychological sequelae. In an effort to document persecution, lawyers seek the assistance of health professionals when preparing their clients' asylum applications. Mental health professionals work to corroborate psychological evidence of the asylum seeker's report of ill treatment through evaluation and presentation of their findings in the form of legal affidavits...

Although cancer immunotherapy based on immune checkpoint inhibitors holds great promise toward many types of cancers, several challenges still remain, associated with low objective response of patient rate as well as systemic side effects. Here, a combination immunotherapy strategy is developed based on a thermogelling reactive oxygen species (ROS)-responsive polypeptide gel for sustained release of anti-programmed cell death-ligand 1 antibody and dextro-1-methyl tryptophan, inhibitor of indoleamine-2,3-dioxygenase with leveraging the ROS level in the tumor microenvironment...

BACKGROUND: Acute appendicitis (AA) is a momentous, emergency, surgical pathology that has still been investigated for both etiopathogenetic unknowns and challenges in diagnosis. Presently, there is little information about the role of microRNAs (miRNAs), which have basic biological functions in the cell, can be a marker, and are associated with various pathologies, in patients with AA. The aim of this study was to investigate the expressions of some miRNAs in AA. METHODS: Overall, 41 miRNAs were screened in 48 individuals comprising 24 patients with AA and 24 healthy controls at Erciyes University Genome and Stem Cell Center (GENKOK)...

Prostate cancer is the second most common malignancy, and the fifth leading cause of cancer-related death among men, worldwide. A major unsolved clinical challenge in prostate cancer is the ability to accurately distinguish indolent cancer types from the aggressive ones. Reprogramming of metabolism is now a widely accepted hallmark of cancer development, where cancer cells must be able to convert nutrients to biomass while maintaining energy production. Metabolomics is the large-scale study of small molecules, commonly known as metabolites, within cells, biofluids, tissues, or organisms...

Mediastinal gray zone lymphoma (MGZL) is a provisional entity with intermediate features between classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma. Outcomes for patients with MGZL are reportedly poorer than those for patients with cHL or primary mediastinal large B-cell lymphoma. Additionally, no standard management guidelines for patients with MGZL are available, primarily due to its recent identification, rarity, and challenges in diagnosis. Although recent several studies have suggested dose-adjusted EPOCH-R (etoposide, doxorubicin, vincristine, cyclophosphamide, prednisolone, and rituximab) may improve outcomes in patients with MGZL, numerous patients still suffer from relapsed/refractory MGZL, and the optimal management for such patients remains uncertain...

Multi-functionalized nanoparticles are of great interest in biotechnology and biomedicine, especially for diagnostic and therapeutic purposes. However, at the moment the characterization of complex, multi-functional nanoparticles is still challenging and this hampers the development of advanced nanomaterials for biological applications. In this work, we have designed a model system consisting of gold nanoparticles functionalized with two differentially-terminated poly(ethylene oxide) ligands, providing both "stealth" properties and protein-binding capabilities to the nanoparticles...

Ambient Mass Spectrometry (MS) analysis is widely used to characterize biological and non-biological samples. Advancements that allow rapid analysis of samples by ambient methods such as Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) and Rapid Evaporative Ionization Mass Spectrometry (REIMS) are discussed. A short, non-comprehensive overview of ambient MS is provided that only contains example applications due to space limitations. A spatially encoded mass spectrometry analysis concept to plan cancer resection is introduced...

Cork oak (Quercus suber) is native to southwest Europe and northwest Africa where it plays a crucial environmental and economical role. To tackle the cork oak production and industrial challenges, advanced research is imperative but dependent on the availability of a sequenced genome. To address this, we produced the first draft version of the cork oak genome. We followed a de novo assembly strategy based on high-throughput sequence data, which generated a draft genome comprising 23,347 scaffolds and 953.3 Mb in size...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder, for which, to date, no effective treatment to ameliorate the clinical manifestations is available. The long-standing view of ALS as affecting only motor neurons has been challenged by the finding that the skeletal muscle plays an active role in the disease pathogenesis and can be a valuable target for therapeutic strategies. In recent years, non-coding RNAs, including microRNAs, have emerged as important molecules that play key roles in several cellular mechanisms involved in the pathogenic mechanisms underlying various human conditions...

Vascular calcification (VC) as a manifestation of perturbed mineral balance, is associated with aging, diabetes and kidney dysfunction, as well as poorer patient outcomes. Due to the current limited understanding of the pathophysiology of vascular calcification, the development of effective preventative and therapeutic strategies remains a significant clinical challenge. Recent evidence suggests that traditional risk factors for cardiovascular disease, such as left ventricular hypertrophy and dyslipidaemia, fail to account for clinical observations of vascular calcification...

Therapies based on regenerative techniques have the potential to radically improve healthcare in the coming years. As a result, there is an emerging need for non-destructive and label-free technologies to assess the quality of engineered tissues and cell-based products prior to their use in the clinic. In parallel, the emerging regenerative medicine industry that aims to produce stem cells and their progeny on a large scale will benefit from moving away from existing destructive biochemical assays towards data-driven automation and control at the industrial scale...
