Cephalotes "turtle" ants host a core group of gut-associated symbionts, but their potential contributions to ant nutrition and disease resistance remain uncharacterized in vitro. To gain a better understanding of the metabolic capability of core symbionts belonging to the Burkholderiales, we cultivated and characterized strain CAG32T, isolated from the guts of Cephalotes rohweri ants. Strain CAG32T was rod-shaped, Gram-negative, motile, and formed pale-white colonies on trypticase soy agar. Optimum growth occurred under an atmosphere of 20% O2 supplemented with 1% CO2...

Mass spectrometry imaging (MSI) is used to determine the relative abundance and spatial distribution of biomolecules such as peptides, proteins, lipids and other organic compounds in tissue sections by their molecular masses. This technique provides a sensitive and label-free approach for high-resolution imaging, and is currently used in an increasing number of biomedical applications such as biomarker discovery, tissue classification and drug monitoring. Owing to technological advances in the past 5 years in diverse MSI strategies, this technology is expected to become a standard tool in clinical practice and provides information complementary to that obtained using existing methods...

Thin-cap fibroatheromas (TCFAs) are considered precursors for plaque rupture and subsequent acute coronary events. We investigated intravascular ultrasound (IVUS) and near-infrared spectroscopy (NIRS) characteristics of lesions that were histopathologic TCFAs. IVUS, NIRS, and histopathology were performed in 271 atherosclerotic lesions from 107 fresh coronary arteries from 54 patients at necropsy. The plaque burden and remodeling index calculated by IVUS and maximum lipid core burden index within any 4-mm segment (maxLCBI4mm) calculated by NIRS were compared among each plaque type based on histopathologic classifications but focusing on TCFA...

OBJECTIVE: Impaired glycaemic control, characteristic of acromegaly, can be exacerbated by treatment with somatostatin analogues (SSAs), particularly those with multireceptor activity. We present data from the PRIMARYS study on the impact of the SSA lanreotide, associated with tumour volume and hormonal improvements, on glucose and other metabolic parameters in acromegaly. DESIGN: PRIMARYS was a 48-week open-label single-arm phase-3b study of lanreotide autogel 120mg/4 weeks...

Intravascular optical coherence tomography (IV-OCT) allows evaluation of atherosclerotic plaques; however, plaque characterization is performed by visual assessment and requires a trained expert for interpretation of the large data sets. Here, we present a novel computational method for automated IV-OCT plaque characterization. This method is based on the modeling of each A-line of an IV-OCT data set as a linear combination of a number of depth profiles. After estimating these depth profiles by means of an alternating least square optimization strategy, they are automatically classified to predefined tissue types based on their morphological characteristics...

Mass spectrometry imaging (MSI) is a label-free analytical technique capable of molecularly characterizing biological samples, including tissues and cell lines. The constant development of analytical instrumentation and strategies over the previous decade makes MSI a key tool in clinical research. Nevertheless, most MSI studies are limited to targeted analysis or the mere visualization of a few molecular species (proteins, peptides, metabolites, or lipids) in a region of interest without fully exploiting the possibilities inherent in the MSI technique, such as tissue classification and segmentation or the identification of relevant biomarkers from an untargeted approach...

Intoxications may lead to life-threatening emergencies. While stabilising the patient, therapy should focus on a rapid and effective elimination of the toxin. General measures for decontamination (gastrointestinal, dermal, ocular) aim to effectively decrease the absorption of the poisonous substance. Further classification of the substance and its properties can assist with the choice of specific treatment options, including dialysis and specific antidotal therapy. In recent years, treatment with lipid emulsions for enhanced elimination of lipophilic substances has become an important therapeutic option...

In populations that have not been selected for family history of disease, it is unclear how commonly pathogenic variants (PVs) in disease-associated genes for rare Mendelian conditions are found and how often they are associated with clinical features of these conditions. We conducted independent, prospective analyses of participants in two community-based epidemiological studies to test the hypothesis that persons carrying PVs in any of 56 genes that lead to 24 dominantly inherited, actionable conditions are more likely to exhibit the clinical features of the corresponding diseases than those without PVs...

BACKGROUND: We assessed the feasibility of using crystal-liquid fugacity ratio (CLFR) as an alternative parameter for intestinal permeability in the biopharmaceutical classification (BCS) of passively absorbed drugs. METHODS: Dose number, fraction of dose absorbed, intestinal permeability, and intrinsic dissolution rate were used as the input parameters. CLFR was determined using thermodynamic parameters i.e., melting point, molar fusion enthalpy, and entropy of drug molecules obtained using differential scanning calorimetry...

Hepatocellular carcinoma is one of the most heterogeneous cancers, as reflected by its multiple grades and difficulty to subtype. In this study, we integrated copy number variation, DNA methylation, mRNA, and miRNA data with the developed "cluster of cluster" method and classified 256 HCC samples from TCGA (The Cancer Genome Atlas) into five major subgroups (S1-S5). We observed that this classification was associated with specific mutations and protein expression, and we detected that each subgroup had distinct molecular signatures...

The World Health Organization (WHO) released a new tumour classification for the genitourinary system in early 2016 after consensus by pathologists with expertise in these organs. It utilized the framework of the 2004 classification and incorporated the most up-to-date information concerning these tumours. In testicular tumours, the majority of the changes occurred in the nomenclature and classification of the germ cell tumours; however, several modifications were also initiated for the non-germ cell tumours...

The current review clarifies the cardiometabolic health effects of high-intensity interval training (HIIT) in adults. A systematic search (PubMed) examining HIIT and cardiometabolic health markers was completed on 15 October 2015. Sixty-five intervention studies were included for review and the methodological quality of included studies was assessed using the Downs and Black score. Studies were classified by intervention duration and body mass index classification. Outcomes with at least 5 effect sizes were synthesised using a random-effects meta-analysis of the standardised mean difference (SMD) in cardiometabolic health markers (baseline to postintervention) using Review Manager 5...

Understanding the behavior of low-dimensional nanomaterials confined in intracellular vesicles has been limited by the resolution of bioimaging techniques and the complex nature of the problem. Recent studies report that long, stiff carbon nanotubes are more cytotoxic than flexible varieties, but the mechanistic link between stiffness and cytotoxicity is not understood. Here we combine analytical modeling, molecular dynamics simulations, and in vitro intracellular imaging methods to reveal 1D carbon nanotube behavior within intracellular vesicles...
