Characterization of two novel cutaneous human papillomaviruses, HPV93 and HPV96.

Two novel human papillomaviruses (HPVs), HPV93 and HPV96, with genomes of 7450 and 7438 bp, respectively, are described. The Ll open reading frame of HPV93 showed highest identity to HPV24 (79%) and that of HPV96 had highest identity to HPV92 (71 %). Real-time PCR for HPV92, 93 and 96 on stripped biopsies from tumours and healthy skin from 269 immunocompetent patients found HPV DNA in 2.6 % of tum

Fibrocytes are a potential source of lung fibroblasts in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis is characterized by the accumulation of fibroblasts/myofibroblasts and aberrant remodeling of the lung parenchyma. However, the sources of fibroblasts in IPF lungs are unclear. Fibrocytes are circulating progenitors of fibroblasts implicated in wound healing and fibrosis. In this study we evaluated evidence for the presence of fibrocytes in the lung of patients with i

Wiring of Photosystem I and Hydrogenase on an Electrode for Photoelectrochemical H2 Production by using Redox Polymers for Relatively Positive Onset Potential

Photosystem I (PSI) is combined with Desulfovibrio gigas hydrogenase for the bioelectrocatalytic photosynthesis of hydrogen at an electrode surface. The activity of these two biocatalysts is linked by two redox polymers; a redox polymer with a relatively positive potential (loaded with an Os complex) is able to reduce PSI and thus facilitates the production of photoexcited electrons, whereas redox

Perspectives for the Brazilian bioethanol sector : The innovation driver

This article addresses the future of Brazil's bioethanol sector, focusing on its capabilities to innovate, its efforts toward producing cellulosic ethanol, and on recently implemented policies. Contrary to what has been argued in the literature, Brazil may not be prepared to face the technological and market challenges now emerging in the biofuels domain worldwide. Important productive investments

On the direction of cross-linguistic influence in the acquisition of object clitics in French and Italian

Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt 2012; Hamann & Belletti 2006). In the present study, we investigate whether placement errors of third person singular OCLs may be due to cross-linguistic influence. We exposed successive (L1 French/L2 Italian and L1 Italian/L2 French) and simultaneous (2L1 Italian/French) Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt, 2012; Hamann & Belletti, 2006). In the present study, we investigate whether placement errors of third person singular OCLs may be due to cross-linguistic influence. We exposed bilingual children (successive L1 French/L2 Italian and L1 Italian/L2 French and simultaneous 2

A codon window in mRNA downstream of the initiation codon where NGG codons give strongly reduced gene expression in Escherichia coli

The influences on gene expression by codons at positions +2, +3, +5 and +7 downstream of the initiation codon have been compared. Most of the +2 codons that are known to give low gene expression are associated with a higher expression if placed at the later positions. The NGG codons AGG, CGG, UGG and GGG, but not GGN or GNG (where N is non-G), are unique since they are associated with a very low g

Ornithine aminotransferase deficiency : Diagnostic difficulties in neonatal presentation

We describe two unrelated cases of ornithine aminotransferase (OAT) deficiency with rare neonatal presentation of hyperammonaemia. The diagnosis in the neonatal presentation of OAT deficiency is hampered as hyperornithinaemia is absent. Enzyme and mutation studies confirmed the diagnosis. OAT deficiency should be included in differential diagnosis of neonatal hyperammonaemia.

Luminescent PhotoCORMs : Enabling/Disabling CO Delivery upon Blue Light Irradiation

The new luminescent carbonyl compounds [Mn(Oxa-H)(CO)3Br] (1) and [Mn(Oxa-NMe2)(CO)3Br] (2) were synthesized and fully characterized. Complexes 1 and 2 showed CO release under blue light (λ453). Spectroscopic techniques and TD-DFT and SOC-TD-DFT calculations indicated that 1 and 2 release the Oxa-H and Oxa-NMe2 coligands in addition to the carbonyl ligands, increasing the luminescence during photo

Cross-disease analysis of depression, ataxia and dystonia highlights a role for synaptic plasticity and the cerebellum in the pathophysiology of these comorbid diseases

Background: There is growing evidence that the neuropsychiatric and neurological disorders depression, ataxia and dystonia share common biological pathways. We therefore aimed to increase our understanding of their shared pathophysiology by investigating their shared biological pathways and molecular networks. Methods: We constructed gene sets for depression, ataxia, and dystonia using the Human P

The present study examines in a quantitative manner the relationship between the attitudes toward gender equality and those toward gender-inclusive language. It also studies how a text written with gender-inclusive language is evaluated and observes what factors can act thereupon. Firstly, statistical analyses show that women have more positive attitudes than men, and that residents in a French-sp

Diffusion tensor distribution imaging of an in vivo mouse brain at ultrahigh magnetic field by spatiotemporal encoding

Diffusion tensor distribution (DTD) imaging builds on principles from diffusion, solid-state and low-field NMR spectroscopies, to quantify the contents of heterogeneous voxels as nonparametric distributions, with tensor “size”, “shape” and orientation having direct relations to corresponding microstructural properties of biological tissues. The approach requires the acquisition of multiple images

The CCSD(T) Model With Cholesky Decomposition of Orbital Energy Denominators

A new implementation of the coupled cluster singles and doubles with approximate triples correction method [CCSD(T)] using Cholesky decomposition of the orbital energy denominators is described. The new algorithm reduces the scaling of CCSD(T) from N-7 to N-6, where N is the number of orbitals. The Cholesky decomposition is carried out using simple analytical expressions that allow us to evaluate

Core localization and sigma( *) delocalization in the O 1s core-excited sulfur dioxide molecule.

Electron-ion-ion coincidence measurements of sulfur dioxide at discrete resonances near the O 1s ionization edge are reported. The spectra are analyzed using a model based upon molecular symmetry and on the geometry of the molecule. We find clear evidence for molecular alignment that can be ascribed to symmetry properties of the ground and core-excited states. Configuration interaction (CI) calcul

Striated domain self-organizing ordered assemblies of transmembrane α-helical peptides and lipids in bilayers

This review summarizes the knowledge on striated domains, which are ordered assemblies of transmembrane peptides and lipids under gel-state conditions. The structure, mechanism of function and utility of this system as a model for domain formation is described, resulting in a molecular description of the domains and a discussion on the relevance of these insights for the function/formation and str

Congenital oral mucosal abnormalities in true umbilical cord knots

Objective: The pathogenesis and clinical significance of true umbilical cord knots remain controversial. Here, we tested the hypothesis of the presence of congenital oral mucosal changes in newborns with true umbilical cord knots. Study design: Seven consecutive infants with true umbilical cord knots and 50 gestational age- and sex-matched controls were enrolled. The proportion of oral frenulum ab

Peak torque and knee kinematics during gait after eccentric isokinetic training of quadriceps in healthy subjects

Objective: To evaluate the effects of eccentric isokinetic training on knee range of motion (ROM) of healthy subjects. Methods: The knee extensor and flexor isokinetic peak torques and ROM of flexion/extension and varus/valgus knee movements during gait of 18 healthy men (21.7 +/- 2.2 years; 1.73 +/- 0.10m; 68.7 +/- 9.4kg; body mass index: 22.6 +/- 2 kg/m(2)) were analyzed, before and after six we

Effect of the calcitonin gene-related peptide (CGRP) receptor antagonist telcagepant in human cranial arteries.

INTRODUCTION: Calcitonin gene-related peptide (CGRP) is a neuronal messenger in intracranial sensory nerves and is considered to play a significant role in migraine pathophysiology. MATERIALS AND METHODS: We investigated the effect of the CGRP receptor antagonist, telcagepant, on CGRP-induced cranial vasodilatation in human isolated cerebral and middle meningeal arteries. We also studied the expre
