Inflammation-induced FGF10 protein deficiency is associated with bronchopulmonary dysplasia (BPD), a chronic lung disease of prematurely born infants characterized by arrested alveolar development. So far, experimental evidence for a direct role of FGF10 in lung disease is lacking. Using the hyperoxia-induced neonatal lung injury as a mouse model of BPD, the impact of Fgf10 deficiency in Fgf10(+/-) versus Fgf10(+/+) pups was investigated. In normoxia, no lethality of Fgf10(+/+) or Fgf10(+/-) pups was observed...

BACKGROUND: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR) may serve as a simple index of the immune function. The aim of this study was to investigate the prognostic significance of NLR, PLR, and LMR in patients with resectable pancreatic ductal adenocarcinoma (PDAC) and to verify whether such biomarkers are associated with changes in populations of lymphoid cells. METHODS: The prognostic implications of blood count parameters were evaluated in a retrospective cohort of 442 subjects undergoing pancreatic resections for PDAC...

Multipotent mesenchymal stem/stromal cells (MSC) were conventionally isolated, through their plastic adherence, from primary tissue digests whilst their anatomical tissue location remained unclear. The recent discovery of defined perivascular and MSC cell marker expression by perivascular cells in multiple tissues by our group and other researchers has provided an opportunity to prospectively isolate and purify specific homogenous subpopulations of multipotent perivascular precursor cells. We have previously demonstrated the use of fluorescent activated cell sorting (FACS) to purify microvascular CD146(+)CD34(-) pericytes and vascular CD34(+)CD146(-) adventitial cells from human skeletal muscle...

Molecular characterization of neuron populations, particularly those controlling threat responses, is essential for understanding the cellular basis of behaviour and identifying pharmacological agents acting selectively on fear-controlling circuitry. Here we demonstrate a comprehensive workflow for identification of pharmacologically tractable markers of behaviourally characterized cell populations. Thy1-eNpHR-, Thy1-Cre- and Thy1-eYFP-labelled neurons of the BLA consistently act as fear inhibiting or 'Fear-Off' neurons during behaviour...

Bioprospecting for novel microalgal strains is key to improving the feasibility of microalgae-derived biodiesel production. Tetraselmis sp. CTP4 (Chlorophyta, Chlorodendrophyceae) was isolated using fluorescence activated cell sorting (FACS) in order to screen novel lipid-rich microalgae. CTP4 is a robust, euryhaline strain able to grow in seawater growth medium as well as in non-sterile urban wastewater. Because of its large cell size (9-22 μm), CTP4 settles down after a six-hour sedimentation step. This leads to a medium removal efficiency of 80%, allowing a significant decrease of biomass dewatering costs...

PURPOSE: Glioblastoma (GBM) ranks among the deadliest solid cancers worldwide and its prognosis has remained dismal, despite the use of aggressive chemo-irradiation treatment regimens. Limited drug delivery into the brain parenchyma and frequent resistance to currently available therapies are problems that call for a prompt development of novel therapeutic strategies. While only displaying modest efficacies as mono-therapy in pre-clinical settings, histone deacetylase inhibitors (HDACi) have shown promising sensitizing effects to a number of cytotoxic agents...

As reported by Alfred Werner in 1911-1912, salts of the formally D3 symmetric [Co(en)3](3+) (en = ethylenediamine) trication were among the first chiral inorganic compounds to be resolved into enantiomers, the absolute configurations of which are denoted Λ (left handed helix) or Δ (right handed helix). After a >100 year dormant period during which few useful reactions of these substitution inert complexes were described, carbon substituted derivatives have recently been found to be potent catalysts for enantioselective organic synthesis...

BACKGROUND: The antioxidant properties of alpha-lipoic acid (ALA) are associated with its ability to reduce iron in cells and tissues, which is partly due to its inhibiting effect on iron uptake from transferrin and its promoting effect on iron deposition into ferritin. However, the relevant mechanisms are unknown. METHODS: We therefore investigated the effects of ALA on the expression of transferrin receptor 1 (TfR1), divalent metal transporter 1 (DMT1), ferroportin 1 (Fpn1) and ferritin in BV-2 microglia cells...

OBJECTIVE: Our previous studies have demonstrated that gut microbial dysbiosis is linked to high blood pressure in patients. This was associated with decreases in butyrate- and acetate- producing microbial populations. Thus, our objective in this study was to investigate the hypothesis that infusion of butyrate would impact dysbiosis, gut immunity and attenuate hypertension. DESIGN AND METHOD: C57B6 mice were divided into 4 groups; Saline infused, Angiotensin II (750ng/kg/min) infused, Ang II infused and butyrate treated (0...

Hematopoietic stem cells (HSCs) have the ability to both self-renew and differentiate into all the mature blood cell lineages and thereby reconstitute the entire blood system. As such, HSCs are therapeutically valuable for treatment of hematological malignances and bone marrow failure. We recently showed that transient glucose elevation elicited dose-dependent effects on HSCs through elevated metabolic activity and subsequent ROS-mediated induction of Hypoxia Inducible Factor 1α (Hif1α). Platelet Derived Growth Factor B (pdgfb), a Hif1α-target, and its receptor, pdgfrb, were significantly upregulated in response to metabolic stimulation...

Advanced glycation end-products (AGEs) resulting from non-enzymatic glycation are one of the major factors involved in diabetes and its secondary complications and diseases. This necessitates our urge to discover new compounds that may be used as potential AGEs inhibitors without affecting the normal structure and function of biomolecules. In the present study, we investigated the inhibitory effects of AgNP (silver nanoparticles) on AGEs formation as well as their inhibitory effects on glycation mediated cell toxicity via ROS production and DNA damage...

In this paper we provide evidence for involvement of chloroplast as alternate organelle for initiating PCD in plants under light and abiotic stress. In animals, mitochondria are the major source of reactive oxygen species (ROS) and key executioner of programmed cell death (PCD). In plants, however, the primary site of generation of ROS is chloroplast and yet its involvement in PCD has not been worked out in details. We found by Evans blue staining that salt (150 mM NaCl)-treated protoplasts obtained from green seedlings had higher rate of cell death than protoplasts obtained from etiolated seedlings...

The reaction of the silyl complex [Rh{Si(OEt)3}(PEt3)3] (1) with 3,3,3-trifluoropropene afforded the rhodium complex [Rh(CH2CHCF3){Si(OEt)3}(PEt3)2] (2) which features a bonded fluorinated olefin. In contrast the rhodium hydrido complex [Rh(H)(PEt3)3] (3) yielded on treatment with 3,3,3-trifluoropropene in the presence of a base the fluorido complex [Rh(F)(PEt3)3] (4) together with 1,1-difluoro-1-propene by C-F bond activation. At low temperature the intermediate fac-[Rh(H)(CH2CHCF3)(PEt3)3] (5) was detected by NMR spectroscopy...
