Ultrastructural and antigenic properties of neural stem cells and their progeny in adult rat subventricular zone.

Neural stem cells (NSCs) in the subventricular zone (SVZ) continuously generate olfactory bulb interneurons in the adult rodent brain. Based on their ultrastructural and antigenic properties, NSCs, transient amplifying precursor cells, and neuroblasts (B, C, and A cells, respectively) have been distinguished in mouse SVZ. Here, we aimed to identify these cell types in rat SVZ ultrastructurally and

Implementation of Choice From Participants' Perspectives: A Study of Community Mental Healthcare Reform in Sweden.

The aim of this study was to explore participants' experiences and opinions about a free-choice system in relation to policy objectives articulated by the national government and local authorities. A case study was conducted. Thirty five informants participated. Qualitative interviews were undertaken. Results discussed are how to address different dimensions of choice, not only where, also what, b

The future of incretin-based therapy: novel avenues-novel targets.

Incretin-based therapy for type 2 diabetes is based on the antidiabetic effects of glucagon-like peptide-1 (GLP-1) and instituted by GLP-1 receptor agonists and dipeptidyl peptidase-4 inhibitors targeting the key islet defects of the disease. The treatment is clinically efficient and safe, and associated with a low risk of adverse events. It can be used both in early and late stages of the disease

The surface emissions trap: A new approach in indoor air purification.

A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contaminated

Prediction of Stage, Grade, and Survival in Bladder Cancer Using Genome Wide Expression Data: A Validation Study.

PURPOSE: To evaluate performances of published gene signatures for the assessment of urothelial carcinoma. EXPERIMENTAL DESIGN: We evaluated 28 published gene signatures designed for diagnostic and prognostic purposes of urothelial cancer. The investigated signatures include eight signatures for stage, five for grade, four for progression, and six for survival. We used two algorithms for classific

Clinical and electrophysiologic outcome in patients with neovascular glaucoma treated with and without bevacizumab.

Purpose. To investigate the clinical and electrophysiologic effect of a single intravitreal injection of bevacizumab for neovascular glaucoma (NVG) after ischemic central retinal vein occlusion (iCRVO). Methods. Nineteen eyes from 19 patients with NVG secondary to iCRVO were randomly allocated to either an intravitreal bevacizumab injection and panretinal photocoagulation (PRP) (10 eyes) or PRP al

Tractable approximations for probabilistic models: the adaptive TAP mean

We develop an advanced mean held method for approximating averages in probabilistic data models that is based on the Thouless-Anderson-Palmer (TAP) approach of disorder physics. In contrast to conventional TAP. where the knowledge of the distribution of couplings between the random variables is required. our method adapts to the concrete couplings. We demonstrate the validity of our approach, whic

Multicomponent Moraxella catarrhalis outer membrane vesicles induce an inflammatory response and are internalized by human epithelial cells.

Moraxella catarrhalis is an emerging human respiratory pathogen in patients with chronic obstructive pulmonary disease (COPD) and in children with acute otitis media. The specific secretion machinery known as outer membrane vesicles (OMVs) is a mechanism by which Gram-negative pathogens interact with host cells during infection. We identified 57 proteins in M. catarrhalis OMVs using a proteomics a

Phase III Trial of Cetuximab With Continuous or Intermittent Fluorouracil, Leucovorin, and Oxaliplatin (Nordic FLOX) Versus FLOX Alone in First-Line Treatment of Metastatic Colorectal Cancer: The NORDIC-VII Study.

PURPOSEThe NORDIC-VII multicenter phase III trial investigated the efficacy of cetuximab when added to bolus fluorouracil/folinic acid and oxaliplatin (Nordic FLOX), administered continuously or intermittently, in previously untreated metastatic colorectal cancer (mCRC). The influence of KRAS mutation status on treatment outcome was also investigated. PATIENTS AND METHODSPatients were randomly ass

Signal transduction pathways of muscarinic receptor mediated activation in the newborn and adult mouse urinary bladder.

OBJECTIVE To study the role of M(2) and M(3) muscarinic receptor subtypes, sources of activator Ca(2+), and mechanisms involved in increased force oscillations in muscarinic contractions in the bladders of newborn and adult mice, as in the adult bladder muscarinic M(3) receptors are considered to mediate the main part of bladder contraction, and this has not been established in the newborn bladder

Covariation of plasma ghrelin and motilin in irritable bowel syndrome.

We have previously shown that ghrelin is mainly localized to the stomach but also occurs, together with the prokinetic hormone motilin, in endocrine cells in the proximal small intestine. This study explored ghrelin and motilin concentrations in plasma in relation to gastrointestinal motility and whether plasma ghrelin is changed in patients with irritable bowel syndrome (IBS). Nine patients with

Mast-cell-dependent secretion of CXC chemokines regulates ischemia-reperfusion-induced leukocyte recruitment in the colon.

BACKGROUND AND AIMS: Recruitment of leukocytes in the tissue microvasculature is considered to be a rate-limiting step in ischemia-reperfusion (I/R)-induced inflammation. The objective of this study was to examine the role of mast cells in CXC-chemokine- and I/R-provoked leukocyte recruitment in the colon. MATERIALS AND METHODS: Balb/c- and mast-cell-deficient mice were challenged with the CXC che

Recognition memory for emotional and neutral faces: An event-related potential study

This study examined emotional influences on the hypothesized event-related potential (ERP) correlates of familiarity and recollection (Experiment 1) and the states of awareness (Experiment 2) accompanying recognition memory for faces differing in facial affect. Participants made gender judgments to positive, negative, and neutral faces at study and were in the test phase instructed to discriminate

Low-grade fibromyxoid sarcoma is difficult to diagnose by fine needle aspiration cytology: a cytomorphological study of eight cases.

Background: Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm with bland morphology and an indolent clinical course, although metastases may develop in approximately 5-10% of the cases. The diagnosis of LGFMS can be difficult to render from fine needle aspiration cytology (FNAC) alone because of morphological overlap with other spindle cell and myxoid lesions. Objective: To determine c

Telomeric associations correlate with telomere length reduction and clonal chromosome aberrations in giant cell tumor of bone.

Giant cell tumor of bone (GCTB) is characterized cytogenetically by frequent telomeric associations (tas). To explore the mechanisms behind the formation of tas in GCTB and to investigate their karyotypic consequences, the frequencies of tas and clonal aberrations other than tas in 20 GCTBs were compared to telomere length and status, as assessed by quantitative PCR, fluorescence in situ hybridiza
