CEP-Controlled Molecular Dissociation by Ultrashort Chirped Laser Pulses

We demonstrate and characterize that a carrier-envelope-phase (CEP)-controlled ultrashortchirped field is an efficient and robust mechanism to modify the dissociation dynamics of molecularhydrogen. Different dissociation pathways are collectively induced and their interference contributeto the kinetic energy release spectra. Chirping is able to efficiently manipulate the interferencesof different dissociation pathways. We demonstrate a linear relationship between chirp and CEP-dependence, dissociation as well as directional electron localization

Mucopolysaccharidosis Type-II with Pathognomonic Skin Appearance: A Case with Pebbling Sign

Mucopolysaccharidosis type-II (MPS-II) is an X-linked lysosomal storage disorder. Here, we report an 8-year-old boy with pebbling sign in the scapular region, coarse facies, claw hand, diastolic murmur, and hepatomegaly. With decreased iduronate-2-sulfatase activity and hemizygous mutation in the IDS gene, the diagnosis was MPS-II. Pebbling sign is a rare but pathognomonic sign of MPS-II

Investigation of Heschl's gyrus and planum temporale in patients with schizophrenia and bipolar disorder: A proton magnetic resonance spectroscopy study

Background: Superior temporal cortices include brain regions dedicated to auditory processing and several lines of evidence suggest structural and functional abnormalities in both schizophrenia and bipolar disorder within this brain region. However, possible glutamatergic dysfunction within this region has not been investigated in adult patients. Methods: Thirty patients with schizophrenia (38.67 ± 12.46. years of age), 28 euthymic patients with bipolar I disorder (35.32 ± 9.12. years of age), and 30 age-, gender- and education-matched healthy controls were enrolled. Proton magnetic resonance spectroscopy data were acquired using a 3.0. T Siemens MAGNETOM TIM Trio MR system and single voxel Point REsolved Spectroscopy Sequence (PRESS) in order to quantify brain metabolites within the left and right Heschl's gyrus and planum temporale of superior temporal cortices. Results: There were significant abnormalities in glutamate (Glu) (F(2,78) = 8.52, p < 0.0001), N-acetyl aspartate (tNAA) (F(2,81) = 5.73, p = 0.005), creatine (tCr) (F(2,83) = 5.91, p = 0.004) and inositol (Ins) (F(2,82) = 8.49, p < 0.0001) concentrations in the left superior temporal cortex. In general, metabolite levels were lower for bipolar disorder patients when compared to healthy participants. Moreover, patients with bipolar disorder exhibited significantly lower tCr and Ins concentrations when compared to schizophrenia patients. In addition, we have found significant correlations between the superior temporal cortex metabolites and clinical measures. Conclusion: As the left auditory cortices are associated with language and speech, left hemisphere specific abnormalities may have clinical significance. Our findings are suggestive of shared glutamatergic abnormalities in schizophrenia and bipolar disorder. © 2013 Elsevier B.V

High efficiency indirect shoot regeneration and hypericin content in embryogenic callus of Hyperi{dotless}cum tri{dotless}quetri{dotless}foli{dotless}um Turra

A method to induce indirect regeneration from Hypericum triquetrifolium Turra was described in the present study. Callus was induced from cotyledon explants of 35 days old aseptic seedlings on semi-solid MS supplemented with IAA (0.5 mg.L-1) combined with BAP (2 mg.L-1). Meristemoids developed on the surface of callus by decreasing of the cytokinins and plantlet regeneration with 100% frequency through these embryogenic calli occured in semi-solid medium when the PGRs were removed completely. Embryogenic calli obtained during the experiments were analyzed for their hypericin content. And they were found to produce hypericin as 48 µg/g DM. Regenerated plantlets were rooted in MS containing 1 mg/L IAA. The highest percentages (94%) of survival of transferred plantlets to free-living circumstances were limited when they were acclimatized in sand: peat: perlite (1:1:1; v/v/v) mixture. © 2010 Academic Journals

Boride Layer Growth Kinetics of AISI H13 Steel Borided with Nano-Sized Powders

Growth kinetics of boride layers in AISI H13 steel was investigated using the pack boriding method at temperatures of 1073, 1173 and 1273 K (800°C, 900°C and 1000°C) for periods of 2, 4 and 6 h with nano-sized boron (NB) and micron-sized Ekabor II powders as boriding agents. The total thickness of the boride layer (including both FeB and Fe2B) after boriding at 1273 K (1000°C) for 6 h was 103.8 μm and 96.5 μm for the NB and Ekabor II specimens, respectively. X-ray diffraction analysis of the boride layers on the surfaces borided with NB and Ekabor II revealed the presence of FeB and Fe2B phases with sawtooth morphology. The FeB/Fe2B volume ratio was higher in the specimens borided with NB. The thickness of the boride layer (FeB + Fe2B) increased with the increasing boriding temperature and time. The FeB layer in the NB specimen displayed a (002) preferred orientation

Unilateral Nevoid Telangiectasia

PubMedID: 15160864Unilateral nevoid telangiectasia is a cutaneous condition consisting of congenital or acquired patches of superficial telangiectases in a unilateral linear distribution. Unilateral nevoid telangiectasia has been associated with elevations of blood estrogen levels and/or an increased number of estrogen receptors in the involved skin. We present a hepatitis-B carrier case with unilateral nevoid telangiectasia on the face and the right side of the neck; she had normal blood estrogen and a normal number of estrogen receptors in the involved skin

Effect of H2O and SO2 on the activity of Pd/TiO2 catalysts in catalytic reduction of NO with methane in the presence of oxygen

Effect of H2O and SO2 on the NO reduction activity of the Pd/titania catalysts was examined in the NO+CH4+O-2 reaction. Steady-state and transient response experiments were performed using a tubular flow reactor. Isotopically labeled methane, (CH4)-C-13, was used in studying the transient behavior of the catalytic system. Reactor effluents were analyzed by using gas chromatography, mass spectrometry, and chemiluminescense techniques. Steady-state reaction experiments showed that the catalyst has a high activity for reduction of NO over a wide oxygen concentration range (0-9800 ppm at 500 degrees C). Higher N-2 selectivities (less NH3) and higher methane conversion values were obtained at higher O-2 concentrations. Experiments also showed that NO conversion was not affected by the presence of water (up to 6%), and higher nitrogen selectivities were obtained at higher H2O concentrations in the feed. On the other hand, significant and irreversible loss of activity was observed in the presence of SO2. The reaction experiments indicated the formation of SO3 and H2S over the catalyst. The post-reaction XPS analysis of the catalyst samples showed that sulfate species were formed on the surface and that the surface palladium was completely converted to pd(2+) State after being exposed to SO2
