Influence of dehulling pretreatment on physicochemical properties of Gleditsia sinensis Lam. gum

The seeds of Gleditsia sinensis Lam., widespread in China, are an important source of galactomannans. G. sinensis gum was extracted from whole seeds using baking, boiling water and acid dehulling pretreatment, respectively. The physicochemical properties of the three isolated G. sinensis gums were studied to evaluate three pretreatment methods. The results illustrated that the properties of G. sin

Development of macrolide resistance in Mycoplasma pneumoniae-infected Swedish patients treated with macrolides.

Background: The proportion of Mycoplasma pneumoniae isolates carrying point mutations in the 23S region of the genome associated with macrolide resistance has increased. We evaluated the probability of developing M. pneumoniae macrolide resistance mutations during macrolide treatment. Methods: M. pneumoniae strains from initial and follow-up oropharyngeal samples from 38 Swedish patients were test

Bedside Diagnosis of Mitochondrial Dysfunction After Malignant Middle Cerebral Artery Infarction

The study explores whether the cerebral biochemical pattern in patients treated with hemicraniectomy after large middle cerebral artery infarcts reflects ongoing ischemia or non-ischemic mitochondrial dysfunction. The study includes 44 patients treated with decompressive hemicraniectomy (DCH) due to malignant middle cerebral artery infarctions. Chemical variables related to energy metabolism obtai

Landlubbers to leviathans: evolution of swimming in mosasaurine mosasaurs

Incremental stages of major evolutionary transitions within a single animal lineage are rarely observed in the fossil record. However, the extraordinarily complete sequence of well preserved material spanning the 27-Myr existence of the marine squamate subfamily Mosasaurinae provides a unique exception. By comparison with extant and extinct analogs, the tail morphology of four mosasaurine genera i

On the Representation of Functions with Gaussian Wave Packets

Abstract in UndeterminedWe introduce Gaussian wave packets in pursuit of representations of functions, in which the representation is invariant under translation, modulation, scale,rotation and anisotropic dilation. Properties of both continuous and discrete representations are discussed. For the discrete (two-dimensional) case, we develop fastalgorithms for the application of the analysis and syn

Targeting smooth muscle microRNAs for therapeutic benefit in vascular disease.

In view of the bioinformatic projection that a third of all protein coding genes and essentially all biological pathways are under control of microRNAs (miRNAs), it is not surprising that this class of small RNAs plays roles in vascular disease progression. MiRNAs have been shown to be involved in cholesterol turnover, thrombosis, glucose homeostasis and vascular function. Some miRNAs appear to be

Exosome and microvesicle mediated phene transfer in mammalian cells.

Extracellular vesicles (EVs), e.g. exosomes and microvesicles, emerge as new signaling organelles in the exchange of information between cells at the paracrine and systemic level. It is clear that these virus like particles carry complex biological information that can elicit a pleiotropic response in recipient cells with potential relevance in physiology as well as in cancer and other pathologica

Evaluation of the Mechanical Properties of PMMA Reinforced with Carbon Nanotubes - Experiments and Modeling

The effective mechanical properties of polymethyl-methacrylate (PMMA) reinforced with carbon nanotubes (CNTs) were evaluated by means of two approaches: experiments and a micromechanical model. With various concentrations of CNTs, two specimen fabrication processes were examined: hot pressing (HP) and injection molding (IM). Experiments included a series of uniaxial tensile tests guided by an ASTM

Genome-wide association study on differentiated thyroid cancer.

Context:Genome-wide association studies (GWASs) of differentiated thyroid cancer (DTC) have identified associations with polymorphisms at 2q35 (DIRC3), 8p12 (NRG1), 9q22.33 (FOXE1) and 14q13.2 (NKX2-1). However, most of the inherited genetic risk factors of DTC remain to be discovered.Objective:Our objective was to identify additional common DTC susceptibility loci.Design:We conducted a GWAS in a

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

Acute hypothalamo-pituitary-adrenal axis response to LPS-induced endotoxemia: expression pattern of kinin type B1 and B2 receptors

Bradykinin (BK) and des-Arg(9)-BK are pro-inflammatory mediators acting via B2 (B2R) and B1 (B1R) receptors, respectively. We investigated the role of B2R and B1R in lipopolysaccharide (LPS)-induced hypothalamopituitary-adrenal (HPA) axis activation in SD rats. LPS given intraperitoneally (ip) up-regulated B1R mRNA in the hypothalamus, both B1R and B2R were up-regulated in pituitary and adrenal gl

Return to work after a serious hand injury.

Objectives: This paper explores factors important for return to work (RTW) in people who have sustained a serious hand injury. Participants: Forty people aged 19-64, with a severe or major hand injury were recruited consecutively during 2005-2007. Methods: A self-administered and study specific questionnaire, including demographic data and standardised questionnaires for function, disability,

Meat and fish consumption and the risk of renal cell carcinoma in the European prospective investigation into cancer and nutrition

Renal cell cancer (RCC) incidence varies worldwide with a higher incidence in developed countries and lifestyle is likely to contribute to the development of this disease. We examined whether meat and fish consumption were related to the risk of RCC in the European Prospective Investigation into Cancer and Nutrition (EPIC). The analysis included 493,179 EPIC participants, recruited between 1992 an

Mortality results from the Goteborg randomised population-based prostate-cancer screening trial

Background Prostate cancer is one of the leading causes of death from malignant disease among men in the developed world. One strategy to decrease the risk of death from this disease is screening with prostate-specific antigen (PSA); however, the extent of benefit and harm with such screening is under continuous debate. Methods In December, 1994, 20 000 men born between 1930 and 1944, randomly sam

Strain fields and mechanical response of a high to medium fissured bentonite clay

This article presents the developments of an ongoing research aimed at modelling the influence of fissuring on the behaviour of clays. In particular, it recalls the main results of an extensive laboratory investigation on a fissured bentonite clay from the south of Italy and presents the data of a new investigation on the evolution with shearing of the strain fields developing within the clay, res

An anthropomorphic liver phantom was examined with four CT systems, each from a different vendor. CTDIvol levels of

Emotions in motion: tourist experiences in time and space

The use of Global Positioning System (GPS) technology enables the study of tourists’ activities and movement patterns in real time. But what does this information tell us about tourists’ subjective experiences? The present paper accounts for the results from four case studies: two event studies and two destination studies. Two of these took place in the wintertime, and two in the summertime. Visit

Development of an efficient statistical volumes of fluid-Lagrangian particle tracking coupling method

The breakup of a liquid jet into irregular liquid structures and droplets leading to the formation of a dilute spray has been simulated numerically. To overcome the shortcomings of certain numerical methods in specific flow regimes, a combined approach has been chosen. The intact liquid core, its primary breakup and the dense spray regime are simulated using the volumes of fluid (VOF) method in co
