Abstract:

The paper deals with the effectiveness of blended phosphonate-based superplasticizers (PHN) for ready mixed concrete. Two phosphonates (PNH1 and PNH2) were added in different percentage to naphthalene sulphonate (NSF) or polycarboxylates (PCEs) based admixtures to improve both compatibility with different cements and workability retention of concrete. The performance of the obtained concrete mixtures was compared to concretes manufactured with the pure NSF or PCE based admixtures. Concretes with the same initial workability (flow table > 580mm) were produced at a temperature of 20 °C and 30

Abstract:

In theory, the distribution of ammonia across cell membranes (Tammi/Tamme) between intracellular and extracellular fluids (ICF and ECF) may be determined by the transmembrane pH gradient (as in mammals), the transmembrane potential (as in teleost fish), or both, depending on the relative permeability of the membranes to NH3 and NH4+ (pNH3/pNH4+). The resting distributions of H+ (via [14C]DMO), ammonia and urea between plasma and skeletal muscle, and the relative excretion rates of ammonia-N and urea-N, were measured in five amphibian species (Bufo marinus, Ambystoma tigrinum, Rana catesbeiana,

ABSTRACT The capsid protein (CP) of the monopartite begomovirus Tomato yellow leaf curl Sardinia virus (TYLCSV), family Geminiviridae, is indispensable for plant infection and vector transmission. A region between amino acids 129 and 152 is critical for virion assembly and insect transmissibility. Two previously described mutants, one with a double Q129P Q134H mutation (PNHD) and another with a further D152E change (PNHE), were found nontransmissible (NT). Another NT mutant with a single N130D change (QDQD) was retrieved from a new mutational analysis. In this study, these three NT mutants and

As expected, ammonia loss from the 25 or 40 mM bicarbonate-containing perfusates was greater than from that containing 5 mM bicarbonate. Furthermore, there was a correlation between ammonia loss and the log mean luminal bicarbonate concentration (r = 0.39, P less than 0.01). From the collected fluid ammonia and bi

ABSTRACT The pnhA gene of Pasteurella multocida encodes PnhA, which is a member of the Nudix hydrolase subfamily of dinucleoside oligophosphate pyrophosphatases. PnhA hydrolyzes diadenosine tetra-, penta-, and hexaphosphates with a preference for diadenosine pentaphosphate, from which it forms ATP and ADP. PnhA requires a divalent metal cation, Mg2+ or Mn2+, and prefers an alkaline pH of 8 for optimal activity. A P. multocida strain that lacked a functional pnhA gene, ACP13, was constructed to further characterize the function of PnhA. The cellular size of ACP13 was found to be 60% less than t

AbstractA cross-polarization detection technique was introduced to enhance the signal-to-noise ratio (SNR) of a plasmonic near-field scanning nanoscope (PNSN) using the anisotropic reflection from a metallic ridge nano-aperture. Assuming that the nano-aperture is an resistor-inductor-capacitor-equivalent circuit, we propose an analytic circuit model to quantitatively predict the relationship between the copolarization and cross-polarization signals of the PNSN. It was found that the magnitude of the cross-polarization signal has an opposite trend with respect to the copolarization signal, prov

Abstract Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hematological disorder, in which almost all hematopoietic cells lack glycosylphosphatidylinositol (GPI)-anchored proteins due to phosphatidylinositol glycan-class A (PIG-A) gene abnormalities at the level of hematopoietic stem cells. It has been reported that several minor PNH clones in patients with aplastic anemia and myelodysplastic syndromes occur at random during the clinical course (Okamoto M et al, Leukemia, 2006), while one or more major PNH clones in patients with typical PNH continue to exist during their clinical cour

Abstract Introduction: Paroxysmal nocturnal hemoglobinuria (PNH) is a nonmalignant clonal disease of hematopoietic stem cells resulting from a somatic mutation in the PIGA gene.

Abstract:

AbstractThe natural history of paroxysmal nocturnal hemoglobinuria (PNH) clinical subcategories (classic PNH and aplastic anemia [AA]/PNH syndrome) is still unknown. We retrospectively studied 460 PNH patients diagnosed in 58 French hematologic centers from 1950 to 2005. The median (SE) follow-up time was 6.8 (0.5) years. The median survival time (SE) was 22 (2.5) years. We identified 113 patients with classic PNH, 224 patients with AA-PNH syndrome, and 93 (22%) intermediate patients who did not fit within these 2 categories. At presentation, classic PNH patients were older, with more frequent

Backgrounds. Pancreatic neuroendocrine neoplasm (pNEN) is a highly heterogeneous entity, presenting widely varied biological behavior as well as long-term prognosis. Reliable biomarkers are urgently needed to make risk stratifications for pNEN patients, which could be beneficial to the development of individualized therapeutic strategy in the clinical practice. Here, we aimed to evaluate the predictive and prognostic roles of serum alkaline phosphatase-to-albumin ratio (APAR) in well-differentiated pNEN patients. Methods. We retrospectively analyzed the pathologically confirmed grade 1/2 pNEN

Abstract:

Pancreatic neuroendocrine neoplasms (pNENs) account for 2–3% of pancreatic malignancies. Peroxiredoxins (Prdxs), which are major cellular antioxidants, are involved in multiple oncogenic signaling pathways. We investigated the role of peroxiredoxin-2 in QGP-1 human pNEN cell line and patient-derived pNEN tissue. To validate the cancer stem cell-like cell characteristics of QGP-1 cells in spheroid culture, in vitro analyses and xenografting were performed. Furthermore, immunohistochemical staining was conducted to verify the overexpression of Prdx2 in pNEN tissue. Prdx2 expression was high at t

Abstract:

A new polyhedral oligomeric silsesquioxane (POSS) designed with eight –(CH2)3–NH–(CH2)2–NH2 groups (PNEN) at its apexes was used as nanocomposite uploading into 1,2-bis(triethoxysilyl)ethane (BTESE)-derived organosilica to prepare mixed matrix membranes (MMMs) for gas separation. The mixtures of BTESE-PNEN were uniform with particle size of around 31 nm, which is larger than that of pure BTESE sols. The characterization of thermogravimetric (TG) and gas permeance indicates good thermal stability. A similar amine-contained material of 3-aminopropyltriethoxysilane (APTES) was doped into BTESE to

Abstract:

The perineuronal net (PNN) is a mesh-like proteoglycan structure on the neuronal surface which is involved in regulating plasticity. The PNN regulates plasticity via multiple pathways, one of which is direct regulation of synapses through the control of AMPA receptor mobility. Since neuronal pentraxin 2 (Nptx2) is a known regulator of AMPA receptor mobility and Nptx2 can be removed from the neuronal surface by PNN removal, we investigated whether Nptx2 has a function in the PNN. We found that Nptx2 binds to the glycosaminoglycans hyaluronan and chondroitin sulphate E in the PNN. Furthermore, i

Abstract:

ABSTRACTAmong the three embryonic germ layers, the mesoderm plays a central role in the establishment of the vertebrate body plan. The mesoderm is specified by secreted signaling proteins from the FGF, Nodal, BMP and Wnt families. No new classes of extracellular mesoderm-inducing factors have been identified in more than two decades. Here, we show that the pinhead (pnhd) gene encodes a secreted protein that is essential for the activation of a subset of mesodermal markers in the Xenopus embryo. RNA sequencing revealed that many transcriptional targets of Pnhd are shared with those of the FGF p

In humans, this genetic event in a hematopoietic stem cell leads to the blood disease paroxysmal nocturnal hemoglobinuria (PNH). PNH has two major clinical presentations: predominantly hemolytic without overt marrow failure, referred to as classic PNH, and PNH clonal expansion in the setting of marrow failure, or the aplastic anemia/PNH syndrome (AA/PNH).

ABSTRACT Pnn/DRS protein is associated with desmosomes and colocalizes with splicing factors in nuclear speckled domains. The potential interaction of Pnn with RNPS1, a pre-mRNA splicing factor and a component of the exon-exon junction complex, prompted us to examine whether Pnn is involved in nuclear mRNA processing. By immunoprecipitation, we found that Pnn associates preferentially with mRNAs produced by splicing in vitro. Oligonucleotide-directed RNase H digestion revealed that Pnn binds to the spliced mRNAs at a position immediately upstream of the splice junction and that 5′ splice site

Abstract:

Abstract Paroxysmal Nocturnal hemoglobinuria (PNH) has been traditionally considered a monogenic disease due to somatic mutations in PIGA gene. While selective immune pressure was implicated in PNH evolution via expansion of a PIGA mutant clone in a privileged environment, history of aplastic anemia (AA) is not always present in a manifest hemolytic PNH. Similarly, expansion of PNH clone after AA therapy does not seem to correlate with the strength of immunosuppression and the quality of response. Our initial studies (J.Clin.Invest.2014; 124 :4529-4538) indicated that additional mutational eve
