Imaging genotyping of functional signaling pathways in lung squamous cell carcinoma using a radiomics approach.

Imaging features can be useful for identifying distinct genomic differences and have predictive power for certain phenotypes attributed to genomic mutations. We aimed to identify predictive imaging biomarkers that underpin genomic alterations and clinical outcomes in lung squamous cell carcinoma (SQCC) using a radiomics approach. In 57 patients with lung SQCC who underwent preoperative computed tomography (CT) and whole-exome DNA sequencing, 63 quantitative imaging features were extracted from CT and 73 clinicoradiological features including imaging features were classified into 8 categories: clinical, global, histogram-based, lung cancer-specific, shape, local, regional, and emphysema.

General and facile purification of dye-labeled oligonucleotides by pH-controlled extraction.

Previously, we reported a method for facile purification of oligonucleotides labeled with hydrophobic dyes, based on the solubility difference between the hydrophilic DNA and unreacted dye. Here, we present a new purification method applicable to any dye regardless of its hydrophobicity. We exploited the population shift of a fluorescent dye in a low-pH aqueous solution from its anionic form toward its neutral form.

A Single Oxidosqualene Cyclase Produces the -Triterpenoid α-Onocerin.

8,14--Triterpenoids are characterized by their unusual open C-ring. Their distribution in nature is rare and scattered in taxonomically unrelated plants. The 8,14--triterpenoid α-onocerin is only known from the evolutionarily distant clubmoss genus and the leguminous genus , which makes the biosynthesis of this -triterpenoid intriguing from an evolutionary standpoint.

DNA methylation in epigenetic inheritance of metabolic diseases through the male germ line.

The global rise in metabolic diseases can be attributed to a complex interplay between biology, behavior and environmental factors. This article reviews the current literature concerning DNA methylation-based epigenetic inheritance (intergenerational and transgenerational) of metabolic diseases through the male germ line. Included are a presentation of the basic principles for DNA methylation in developmental programming, and a description of windows of susceptibility for the inheritance of environmentally induced aberrations in DNA methylation and their associated metabolic disease phenotypes.

Utilizing Co/Co Redox Couple in P2-Layered NaCoMnTiO Cathode for Sodium-Ion Batteries.

Developing sodium-ion batteries for large-scale energy storage applications is facing big challenges of the lack of high-performance cathode materials. Here, a series of new cathode materials NaCo Mn TiO for sodium-ion batteries are designed and synthesized aiming to reduce transition metal-ion ordering, charge ordering, as well as Na and vacancy ordering. An interesting structure change of NaCo Mn TiO from orthorhombic to hexagonal is revealed when Co content increases from = 0 to 0.

Direct assignment of C solid-state NMR signals of TFF ATP synthase subunit c-ring in lipid membranes and its implication for the ring structure.

FF-ATP synthase catalyzes ATP hydrolysis/synthesis coupled with a transmembrane H translocation in membranes. The F c-subunit ring plays a major role in this reaction. We have developed an assignment strategy for solid-state C NMR (ssNMR) signals of the F c-subunit ring of thermophilic Bacillus PS3 (TF c-ring, 72 residues), carrying one of the basic folds of membrane proteins.

Highly Efficient Thin-Film Transistor via Cross-Linking of 1T Edge Functional 2H Molybdenum Disulfides.

Thin-film transistors (TFTs) have received great attention for their use in lightweight, large area, and wearable devices. However, low crystalline materials and inhomogeneous film formation limit the realization of high-quality electrical properties for channels in commercial TFTs, especially for flexible electronics. Here, we report a field-effect TFT fabricated via cross-linking of edge-1T basal-2H MoS sheets that are prepared by edge functional exfoliation of bulk MoS with soft organic exfoliation reagents.

Overlaps and uncertainties of smoking-related idiopathic interstitial pneumonias.

Smoking-related interstitial lung disease (ILD) consists of a heterogeneous group of disorders that are considered a distinct entity. The 2013 American Thoracic Society and European Respiratory Society recommendations classified respiratory bronchiolitis (RB)/RB-ILD and desquamative interstitial pneumonia (DIP) as smoking-related idiopathic interstitial pneumonias (IIPs). The overlapping histopathological and radiological patterns of smoking-related IIPs must be considered.

Extracellular vesicles derived from MSCs activates dermal papilla cell in vitro and promotes hair follicle conversion from telogen to anagen in mice.

Hair loss is a common medical problem. In this study, we investigated the proliferation, migration, and growth factor expression of human dermal papilla (DP) cells in the presence or absence of treatment with mesenchymal stem cell extracellular vesicles (MSC-EVs). In addition, we tested the efficacy of MSC-EV treatment on hair growth in an animal model.

Inflammatory biomarkers and radiologic measurements in never-smokers with COPD: A cross-sectional study from the CODA cohort.

Various biomarkers have emerged as potential surrogates to represent various subgroups of chronic obstructive pulmonary disease (COPD), which manifest with different phenotypes. However, the biomarkers representing never-smokers with COPD have not yet been well elucidated. The aim of this study was to evaluate the associations of certain serum and radiological biomarkers with the presence of COPD in never-smokers.

The TriForC database: a comprehensive up-to-date resource of plant triterpene biosynthesis.

Triterpenes constitute a large and important class of plant natural products with diverse structures and functions. Their biological roles range from membrane structural components over plant hormones to specialized plant defence compounds. Furthermore, triterpenes have great potential for a variety of commercial applications such as vaccine adjuvants, anti-cancer drugs, food supplements and agronomic agents.

Cord blood-derived T cells allow the generation of a more naïve tumor-reactive cytotoxic T-cell phenotype.

Background: Transplantation of hematopoietic stem cells (HSCs) from peripheral blood (PB) or cord blood (CB) is well established. HSCs from CB are associated with a lower risk of graft-versus-host disease (GVHD), but antigen-independent expanded CB- and PB-derived T cells can induce GVHD in allo-HSC recipients. CB-derived cells might be more suitable for adoptive immunotherapy as they have unique T-cell characteristics.

The arms race between heliconiine butterflies and Passiflora plants - new insights on an ancient subject.

Heliconiines are called passion vine butterflies because they feed exclusively on Passiflora plants during the larval stage. Many features of Passiflora and heliconiines indicate that they have radiated and speciated in association with each other, and therefore this model system was one of the first examples used to exemplify coevolution theory. Three major adaptations of Passiflora plants supported arguments in favour of their coevolution with heliconiines: unusual variation of leaf shape within the genus; the occurrence of yellow structures mimicking heliconiine eggs; and their extensive diversity of defence compounds called cyanogenic glucosides.

Diagnosis of bronchial artery aneurysm by computed tomography: a case report.

Bronchial artery aneurysm is a rare vascular abnormality, with an incidence of <1% based on diagnosis by selective bronchial angiography. It is manifested in various forms, ranging from an incidental finding on radiologic examination to life-threatening hemorrhage resulting from aneurysm rupture. We report a case of a 60-year-old man with a mediastinal bronchial artery aneurysm which was incidentally detected on chest computed tomography.

Promotion of hair growth by newly synthesized ceramide mimetic compound.

Based on the crucial roles of ceramides in skin barrier function, use of ceramides or their structural mimetic compounds, pseudoceramides, as cosmetic ingredients are getting more popular. While currently used pseudoceramides are intended to substitute the structural roles of ceramides in stratum corneum, development of bioactive pseudoceramides has been repeatedly reported. In this study, based on the potential involvement of sphingolipids in hair cycle regulation, we investigated the effects of newly synthesized pseudoceramide, bis-oleamido isopropyl alcohol (BOI), on hair growth using cultured human hair follicles and animal models.

Spatial separation of the cyanogenic β-glucosidase ZfBGD2 and cyanogenic glucosides in the haemolymph of larvae facilitates cyanide release.

Low molecular weight compounds are typically used by insects and plants for defence against predators. They are often stored as inactive β-glucosides and kept separate from activating β-glucosidases. When the two components are mixed, the β-glucosides are hydrolysed releasing toxic aglucones.

Social Network Structures of Breast Cancer Patients and the Contributing Role of Patient Navigators.

Background: Minority women in the U.S. continue to experience inferior breast cancer outcomes compared with white women, in part due to delays in care delivery.

Fecal microbiota transplantation for refractory Crohn's disease.

Approximately one-third of patients with Crohn's disease do not respond to conventional treatments, and some experience significant adverse effects, such as serious infections and lymphoma, and many patients require surgery due to complications. Increasing evidence suggests that specific changes in the composition of gut microbiota, termed as dysbiosis, are a common feature in patients with inflammatory bowel disease (IBD). Dysbiosis can lead to activation of the mucosal immune system, resulting in chronic inflammation and the development of mucosal lesions.

Appropriate Minimal Dose of Gadobutrol for 3D Time-Resolved MRA of the Supra-Aortic Arteries: Comparison with Conventional Single-Phase High-Resolution 3D Contrast-Enhanced MRA.

Background And Purpose: The development of nephrogenic systemic fibrosis and neural tissue deposition is gadolinium dose-dependent. The purpose of this study was to determine the appropriate minimal dose of gadobutrol with time-resolved MRA to assess supra-aortic arterial stenosis with contrast-enhanced MRA as a reference standard.

Materials And Methods: Four hundred sixty-two consecutive patients underwent both standard-dose contrast-enhanced MRA and low-dose time-resolved MRA and were classified into 3 groups; group A (a constant dose of 1 mL for time-resolved MRA), group B (2 mL), or group C (3 mL).

Spatially Assembled Bilayer Cell Sheets of Stem Cells and Endothelial Cells Using Thermosensitive Hydrogels for Therapeutic Angiogenesis.

Although the coculture of multiple cell types has been widely employed in regenerative medicine, in vivo transplantation of cocultured cells while maintaining the hierarchical structure remains challenging. Here, a spatially assembled bilayer cell sheet of human mesenchymal stem cells and human umbilical vein endothelial cells on a thermally expandable hydrogel containing fibronectin is prepared and its effect on in vitro proangiogenic functions and in vivo ischemic injury is investigated. The expansion of hydrogels in response to a temperature change from 37 to 4 °C allows rapid harvest and delivery of the bilayer cell sheet to two different targets (an in vitro model glass surface and in vivo tissue).

High neutrophil : lymphocyte ratio is associated with refractory Kawasaki disease.

Background: The clinical significance of the neutrophil : lymphocyte ratio (NLR) has not yet been fully elucidated in Kawasaki disease (KD). The purpose of this study was to investigate the relationship between NLR and response to i.v.

The genome sequence of Barbarea vulgaris facilitates the study of ecological biochemistry.

The genus Barbarea has emerged as a model for evolution and ecology of plant defense compounds, due to its unusual glucosinolate profile and production of saponins, unique to the Brassicaceae. One species, B. vulgaris, includes two 'types', G-type and P-type that differ in trichome density, and their glucosinolate and saponin profiles.
