OBJECTIVE: To explore if climbazole enhances retinoid-associated biological activities in vitro and in vivo. METHODS: Primary human dermal fibroblasts (HDFs) were treated from six to 48 hours with either retinoids (retinol, retinyl propionate, retinyl palmitate) alone or in combination with climbazole, then assessed for cellular retinoic acid-binding protein 2 (CRABP2) mRNA expression by RT-qPCR. Next, skin equivalent (SE) cultures were topically treated with a retinol or retinyl propionate, and with or without climbazole, then measured for biological changes in retinoid biomarkers...

While 2/3 of patients with ATRT are less than 3 years at diagnosis, the literature suggests younger children present with more aggressive disease and poorer outcome. However, little data exist on characteristics and outcome of patients diagnosed with ATRT in the first year of life. In particular, it is unclear whether they access similar treatments as do older children. We compared the cohort of patients ≤12 months from the Canadian ATRT registry to all cases extracted from the literature reported between 1996 and 2014 to describe their clinical and treatment characteristics, and potential prognostic factors...

BACKGROUND: Intravascular ultrasound (IVUS) allows intraluminal imaging of blood vessels rather than the one-dimensional luminal outline depicted by digital subtraction angiography (DSA). Despite extensive literature in multiple adult vascular diseases, IVUS has not been directly compared to DSA in pediatric and adolescent vascular pathologies. OBJECTIVE: The purpose of this manuscript is to compare absolute luminal diameter measurements obtained via IVUS and DSA during a variety of pediatric endovascular procedures...

: KCNQ2 potassium channels are critical for normal brain function, as both loss-of-function and gain-of-function KCNQ2 variants can lead to various forms of neonatal epilepsy. Despite recent progress, the full spectrum of consequences as a result of KCNQ2 dysfunction in neocortical pyramidal neurons is still unknown. Here, we report that conditional ablation of Kcnq2 from mouse neocortex leads to hyperexcitability of layer 2/3 (L2/3) pyramidal neurons, exhibiting an increased input resistance and action potential frequency, as well as a reduced medium afterhyperpolarization (mAHP), a conductance partly mediated by KCNQ2 channels...

OBJECTIVE: To examine the effectiveness of a multidisciplinary, team-based approach to management of cesarean hysterectomy. METHODS: In a retrospective chart review, data were analyzed from a quality assurance database of hysterectomies performed after cesarean delivery at one institution in the USA. Patients were identified through billing codes for cesarean delivery, cross-referenced to codes for hysterectomy. Demographic, reproductive, and outcome data were compared before (2000-2005) and after (2011-2013) implementation of a multidisciplinary team-based protocol...

BACKGROUND: Pancreatic cancer is a lethal malignancy that frequently acquires resistance to conventional chemotherapies often associated with overexpression of inhibitors of apoptosis proteins (IAPs). We have recently described a novel means to deliver second mitochondria-derived activator of caspases (SMAC) mimetics selectively to cancer cells employing the sigma-2 ligand/receptor interaction. The intrinsic death pathway agonist SMAC offers an excellent opportunity to counteract the anti-apoptotic activity of IAPs...

Diffuse intrinsic pontine glioma (DIPG), a rare, often fatal childhood brain tumor, remains a major therapeutic challenge. In 2012, investigators, funded by the DIPG Collaborative (a philanthropic partnership among 29 private foundations), launched the International DIPG Registry (IDIPGR) to advance understanding of DIPG. Comprised of comprehensive deidentified but linked clinical, imaging, histopathological, and genomic repositories, the IDIPGR uses standardized case report forms for uniform data collection; serial imaging and histopathology are centrally reviewed by IDIPGR neuro-radiologists and neuro-pathologists, respectively...

CONTEXT: Transnational alcohol corporations (TACs) employ a range of strategies to achieve their business objectives, including attempts to frame perceptions of their activities in media debates. TACs aim to achieve a favourable regulatory environment by presenting themselves as socially responsible actors. However, the need to secure financial investment means they must also emphasise their potential for growth. This article investigates tensions between these objectives in coverage of the global alcohol industry in the UK print media...

BACKGROUND: Despite considerable efforts by scientific research, pancreatic cancer is the fourth leading cause of cancer related mortalities. Sigma-2 receptors, which are overexpressed in several tumors, represent promising targets for triggering selective pancreatic cancer cells death. METHODS: We selected five differently structured high-affinity sigma-2 ligands (PB28, PB183, PB221, F281 and PB282) to study how they affect the viability of diverse pancreatic cancer cells (human cell lines BxPC3, AsPC1, Mia PaCa-2, and Panc1 and mouse Panc-02, KCKO and KP-02) and how this is reflected in vivo in a tumor model...

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) have increased cardiovascular risk. Natriuretic peptides (NP) in other populations are useful in identifying cardiovascular disease, stratifying risk, and guiding therapy. METHODS: We performed a systematic literature review to examine NP in COPD, utilising Medline, EMBASE, and the Cochrane Library. RESULTS: Fifty one studies were identified. NP levels were lower in stable compared to exacerbation of COPD, and significantly increased with concomitant left ventricular systolic dysfunction or cor pulmonale...

An automated microfluidic sample preparation multiplexer (SPM) has been developed and evaluated for Ebola virus detection. Metered air bubbles controlled by microvalves are used to improve bead-solution mixing thereby enhancing the hybridization of the target Ebola virus RNA with capture probes bound to the beads. The method uses thermally stable 4-formyl benzamide functionalized (4FB) magnetic beads rather than streptavidin coated beads with a high density of capture probes to improve the target capture efficiency...

OBJECTIVE: To assess the potential utility of a novel non-invasive muscle oxygen measurement to determine the presence of muscle hypoxia in patients with anaemia. BACKGROUND: Recent assessment of the risk/benefit ratio of blood transfusion has led to clinical strategies optimising transfusion decisions. These decisions are primarily based on haematocrit (Hct) but not oxygen delivery, the primary function of red blood cells (RBCs). We hypothesised that muscle oxygenation (MOx) would correlate with Hct in patients with anaemia and may be a physiologically relevant determinant of the transfusion threshold...
