Biocatalytic potential of vanillin aminotransferase from Capsicum chinense.

The conversion of vanillin to vanillylamine is a key step in the biosynthetic route towards capsaicinoids in pungent cultivars of Capsicum sp. The reaction has previously been annotated to be catalysed by PAMT (putative aminotransferase; [GenBank: AAC78480.1, Swiss-Prot: O82521]), however, the enzyme has previously not been biochemically characterised in vitro.

Rapid increase in myocardial infarction risk following diagnosis of rheumatoid arthritis amongst patients diagnosed between 1995 and 2006

Holmqvist ME, Wedren S, Jacobsson LTH, Klareskog L, Nyberg F, Rantapaa-Dahlqvist S, Alfredsson L, Askling J (Institute of Environmental Medicine, Karolinska Institutet, Stockholm; Karolinska Institutet/Karolinska Hospital, Stockholm; Malmo University Hospital, Malmo; AstraZeneca R&D, Molndal; and Umea University Hospital, Umea, Sweden) Rapid increase in myocardial infarction risk following dia

Review of comparative LCAs of food waste management systems - Current status and potential improvements.

Twenty-five comparative cycle assessments (LCAs) addressing food waste treatment were reviewed, including the treatment alternatives landfill, thermal treatment, compost (small and large scale) and anaerobic digestion. The global warming potential related to these treatment alternatives varies largely amongst the studies. Large differences in relation to setting of system boundaries, methodologica

HOST EPIGENETIC REGULATOR BMI1 AND VIRAL FIBER PROTEIN FOR EQUILIBRIUM BETWEEN ADENOVIRUS AND HOST

Popular Abstract in Swedish Adenovirus från människa (Ad) används ofta vid genterapi mot cancer, vaccinutveckling och genöverföring. Modifierade Ad5 och Ad2 virus har framgångsrikt använts som cancercelldödande (onkolytiska) agens i experimentella studier som dock inte kunnat överföras till kliniskt bruk av flera skäl, inklusive bristande spridning av virusinfektionen inom tumörvävnaden. De onkolyHuman adenoviruses (Ads) are broadly used in cancer gene therapy, vaccine development and gene delivery. The modified Ad5 or Ad2 viruses have been successfully used as oncolytic agents in pre-clinical studies. However they could not be translated into clinic utility due to a number of limitations including inefficient Ad spread among tumor cells. The cancer cell killing capacity of oncolytic Ad is

t(3;21)(q22;q22) leading to truncation of the RYK gene in atypical chronic myeloid leukemia

The analysis of a small number of patients with atypical chronic myeloid leukemia showing balanced chromosomal translocations has revealed diverse tyrosine kinase fusion genes, most commonly involving FGFR1, PDGFRA, PDGFRB, JAK2, and ABL. We present a case of aCML with a 3q22;21q22-translocation that led to truncation of the receptor-like tyrosine kinase (RYK) gene and its juxtaposition with seque

Role of NFAT (nuclear factor of activated T cells) in vascular smooth muscle

The calcium-dependent transcription factor NFAT was first described as a key player in immune cell regulation. Since then, NFAT signaling has been shown to be crucial for normal vascular development during embryogenesis. This pathway is also an important regulator of cell growth and differentiation in various cell types, however, the functional significance of NFAT in the vasculature is largely un

Gravoturbulent Planetesimal Formation: The Positive Effect of long-lived Zonal Flows

Recent numerical simulations have shown long-lived axisymmetric sub- and super-Keplerian flows in protoplanetary disks. These zonal flows are found in local as well as global simulations of disks unstable to the magnetorotational instability. This paper covers our study of the strength and lifetime of zonal flows and the resulting long-lived gas over- and underdensities as functions of the azimuth

Från ämbetsman till ämbetsbärare : förändringar speglade i anmälningar mot präster under tre brytningstider

Popular Abstract in Swedish Avhandlingen tar upp frågor om prästernas arbetsmiljö och deras roll och identitet. I inledningskapitlet framhölls att flera faktorer är viktiga för en undersökning om prästernas arbetsmiljö och för utformningen av prästrollen och prästidentiteten. Det omgivande samhället, de organisatoriska ramarna och de förväntningar som ställs på prästerna är några sådana faktorer, In this dissertation the work environment and the roles and identities of the clergy in the Church of Sweden are investigated. It is said in the first chapter that there are several factors influencing the work environment and that these factors are important for the formation of the roles and identities of the clergy. The surrounding society, the organization, and the expectations directed at the

In-vivo dark-field and phase-contrast x-ray imaging.

Novel radiography approaches based on the wave nature of x-rays when propagating through matter have a great potential for improved future x-ray diagnostics in the clinics. Here, we present a significant milestone in this imaging method: in-vivo multi-contrast x-ray imaging of a mouse using a compact scanner. Of particular interest is the enhanced contrast in regions related to the respiratory sys

Subgel transition in diluted vesicular DODAB dispersions

We have characterized the lipid chain freezing in dilute aqueous vesicle dispersions of the cationic lipid dioctadecyldimethylammonium bromide (DODAB) using wide and small angle X-ray scattering, solid state NMR, DSC, turbidity and density measurements. The lipids freeze in two steps. Above 40 degrees C the chains are fluid and the lipids are in a so-called liquid-crystalline state. When cooling b

Epidemiological studies of risk factors for injuries in an adult population

Popular Abstract in Swedish Dödligheten i skador i Sverige har under de senaste årtiondena minskat, en minskning som idag dock har planat ut. Antalet dödade i transportolyckor och i arbetsplatsolyckor i Sverige har minskat under de senaste 40 åren vilket kan ses som ett resultat av ett effektivt säkerhetsarbete. När det gäller fallolyckor så har däremot andelen som dör av sina skador ökat markant Injuries are often associated with long-term suffering and lowered functioning, and personal injuries impose a huge burden on medical care and health services in addition to the costs associated with impaired functional ability. Each year in Sweden, falling accidents are experienced by a third of those aged 60 or over and half of those aged 80 or over, while injuries from traffic accidents still a

Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS detector

A search has been performed for the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transverse momentum. Such a final state may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon

Search for new particles decaying to ZZ using final states with leptons and jets with the ATLAS detector in root s=7 TeV proton-proton collisions

A search is presented for a narrow resonance decaying to a pair of Z bosons using data corresponding to 1.02 fb(-1) of integrated luminosity collected by the ATLAS experiment from pp collisions at root s= 7 TeV. Events containing either four charged leptons (llll) or two charged leptons and two jets (lljj) are analyzed and found to be consistent with the Standard Model background expectation. Lowe

We report on the fabrication and characterisation of a gold-nanoparticle (AuNP)-based mediatorless sugar/oxygen biofuel cell (BFC) operating in neutral sugar-containing buffers and human physiological fluids, such as blood and plasma. First, Corynascus thermophilus cellobiose dehydrogenase (CtCDH) and Myrotheciumverrucaria bilirubin oxidase (MvBOx), used as anodic and cathodic bioelements, respect

Disruption of the Eng18B ENGase Gene in the Fungal Biocontrol Agent Trichoderm atroviride Affetcs Growth Conidation and Antagonistic Ability

The recently identified phylogenetic subgroup B5 of fungal glycoside hydrolase family 18 genes encodes enzymes with mannosyl glycoprotein endo-N-acetyl-b-D-glucosaminidase (ENGase)-type activity. Intracellular ENGase activity is associated with the endoplasmic reticulum associated protein degradation pathway (ERAD) of misfolded glycoproteins, although the biological relevance in filamentous fungi

[(BINAP)Re(O)Cl-3] as an efficient catalyst for olefination of chiral alpha-substituted aliphatic aldehydes

A convenient one-pot preparation of [(BINAP) Re(O)Cl-3] (6) is described. This complex was demonstrated to be an efficient catalyst for the olefination of aldehydes by reaction with alpha-diazo esters, with essentially quantitative yields and up to 98:2 geometric selectivity.
