Scrub typhus, caused by a Gram-negative obligately intracellular coccobacillus, Orientia tsutsugamushi, is a long neglected but important tropical disease. Orientia tsutsugamushi causes illness in one million people each year, and 1 billion people are at risk. Without appropriate diagnosis and treatment, the disease can cause severe multiorgan failure with a case fatality rate of 7-15%. The current gaps in knowledge of immunity include the unknown mechanisms of host immunity to O. tsutsugamushi. Using an intravenous (i...

For drug delivery to the lungs, the aerodynamic size of drug particles plays a predominant role in determining the sites of deposition in the airway, and the particles with the size less than 2 microns are highly expected as they will be preferably delivered to the ideal site of alveolar regions. In this paper, a novel platform technology has been developed, where the water (containing pharmaceutically active agents)-in-oil (w/o) microemulsions were spray-dried to generate nanosized drug particles that were able to be homogeneously dispersed in the propellant to form an exceptionally stable suspensions with no precipitates or flocculates during a long time storage...

BACKGROUND: The increasing sub-classification of cancer patients due to more detailed molecular classification of tumors, and limitations of current trial designs, require innovative research designs. We present the design, governance and current standing of three comprehensive nationwide cohorts including pancreatic, esophageal/gastric, and colorectal cancer patients (NCT02070146). Multidisciplinary collection of clinical data, tumor tissue, blood samples, and patient-reported outcome (PRO) measures with a nationwide coverage, provides the infrastructure for future and novel trial designs and facilitates research to improve outcomes of gastrointestinal cancer patients...

INTRODUCTION: Detection of mutations in patients with myeloid neoplasms (MNs) has shown great potential for diagnostic and prognostic purposes. Next-generation sequencing (NGS) is currently implemented for the diagnostic profiling of the four major MN subgroups. METHODS: First, we validated the targeted NGS approach using the TruSight Myeloid panel. Next, we screened 287 patients with a clinical suspicion of MN and 61 follow-up patients with documented MN. RESULTS: Validation of the NGS workflow resulted in maximal precision, accuracy, sensitivity, and specificity for gene variants with an allele frequency of at least 5% and a minimal read depth of 300...

The most common form of hypertension in young adults is isolated diastolic hypertension. Diastolic arterial pressure is determined by the total peripheral resistance and depends on both vascular hindrance and blood viscosity. The aim of our work was to study the efficiency of pentoxifylline (PTX) in young spontaneously hypertensive rats (SHRs) during the development of arterial hypertension. The effects of a treatment course with PTX (100 mg/kg/day p.o. for 6 weeks, from 5 to 11 weeks old) on the mean, systolic, and diastolic blood pressure (BP); stroke volume; cardiac output; total peripheral resistance (TPR); whole blood viscosity (BV); plasma viscosity; hematocrit; RBC aggregation and deformability; local cerebral blood flow (lCBF); and microvascularization of the visual cortex were studied in SHRs in comparison with control SHRs and Wistar Kyoto rats...

The problem of using the surfactant micellar aqueous solutions as reaction media centers on estimating the polarity of the micellar pseudophase. The most popular approach is the utilization of solvatochromic dyes. Among the last, the strongest ones are the dipolar pyridinium N-phenolate dyes. The complication of such approach, however, consists in the non-uniform character of the environment of the indicator fixed in the micellar pseudophase. The aim of this study is to reveal the character of localization and orientation of the standard solvatochromic pyridinium N-phenolate dye, 4-(2,4,6-triphenylpyridinium-1-yl)-2,6-diphenylphenolate, the so-called Reichardt's dye, within the micellar pseudophase of an anionic (sodium n-dodecyl sulfate, SDS) and cationic (cetyltrimethylammonium bromide, CTAB) surfactants using MD simulations...

Hydrogen (H) bonds are of fundamental importance in a wide range of molecular sciences. While the study of two-center H-bonding AH is well advanced, much remains to be learned in a quantitative and definitive manner for complexes with multiple H-bonds. Exemplary cases are in the category of alpha hydroxy carboxylic acids, i.e., the complexes of glycolic acid with water and formic acid. In glycolic acid, an intramolecular H-bond forms between the carboxyl group and the alpha OH group. The alpha OH stretching frequency may be affected upon complexing with water or formic acid...

Restorative proctocolectomy with an ileoanal pouch anastomosis (IAPA) is the surgical therapy of choice for patients with refractory ulcerative colitis and/or associated (pre)neoplastic lesions. It is predominantly performed laparoscopically. Reconstruction with a J‑pouch is the most frequently applied variant due to the ideal combination of technical simplicity and good long-term results. In the present review, potential postoperative pouch complications, their risk factors, diagnostics and surgical management, as well as mid-term and long-term quality of life after pouch construction are differentially presented based on the current literature...

Cardiomyopathies are complex diseases of multifactorial pathogenesis and have a high morbidity and mortality. Over the past decades, several revisions of classifications and definitions of cardiomyopathies have been proposed, primarily focusing on the phenotypic characterization of cardiomyopathies. The MOGE(S) classification system published in 2013 encompasses the classification of rapidly growing knowledge on genetic mutations, acquired causes (i.e., intramyocardial inflammation, viral infections), and further conditions involved in the induction of cardiomyopathies (e...

Topological insulators have become one of the most prominent research topics in materials science in recent years. Specifically, Bi2Te3 is one of the most promising for technological applications due to its conductive surface states and insulating bulk properties. Herein, we contrast the bulk and surface structural environments of dopant ions Cr, Mn, Fe, Co, Ni, and Cu in Bi2Te3 thin films in order to further elucidate this compound. Our measurements show the preferred oxidation state and surrounding crystal environment of each 3d-metal atomic species, and how they are incorporated into Bi2Te3...

Chronic ACTH exposure (eg Cushings) is associated with adrenal hypertrophy and steroidogenesis. The underlying molecular processes in mice have been analysed by microarray, histological and immunohistochemical techniques. Synacthen infused for 2weeks markedly increased adrenal mass and plasma corticosterone levels. Microarray analysis found greater than 2-fold changes in expression of 928 genes (P<0.001; 397 up, 531 down). These clustered in pathways involved in signalling, sterol/lipid metabolism, cell proliferation/hypertrophy and apoptosis...

Thiazide diuretics, commonly used antihypertensives, may cause QT interval (QT) prolongation, a risk factor for highly fatal and difficult to predict ventricular arrhythmias. We examined whether common single-nucleotide polymorphisms (SNPs) modified the association between thiazide use and QT or its component parts (QRS interval, JT interval) by performing ancestry-specific, trans-ethnic and cross-phenotype genome-wide analyses of European (66%), African American (15%) and Hispanic (19%) populations (N=78 199), leveraging longitudinal data, incorporating corrected standard errors to account for underestimation of interaction estimate variances and evaluating evidence for pathway enrichment...

In a recently published paper (Pfaar et al., 2016), a Task Force of the Immunotherapy and Aerobiology and Pollution Interest Groups of the EAACI suggested specific criteria for the definition of pollen exposure times for three types of pollen events: (a) Pollen Season (PS) start and end, (b) high pollen season (or Peak Pollen Period-PPP) start and end, and (c) high pollen days. Species addressed included Birch, Grasses, Cypress, Olive, and Ragweed. Two important questions arise from the aforementioned definitions: (i) do they lead to a narrow (thus well defined) time interval identifying start and end event dates (robustness of the criteria) and (ii) if slightly altered, will they result to a narrow (thus again well defined) fluctuation of start and end event dates (sensitivity of the criteria)? In an effort to provide with responses to aforementioned questions, we analyzed Poaceae pollen count data coming from Germany (up to 40 pollen monitoring stations, years 2012-2016)...
