Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas((R)) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32muL) with high or intermediate a

A method for screening of ketone biotransformations was developed and applied to the identification of Baeyer-Villiger monooxygenase (BVMO) activity. The method was based on the formation of a purple coloured product on reaction between an enolizable ketone and 3,5-dinitrobenzoic acid in an alkaline solution. Absorbance of the colour decreased with the size of the cycloketone ring. Stoichiometric

Uridine phosphorylase (UP), a key enzyme in the pyrimidine salvage pathway catalyzes the reversible phosphorolysis of uridine or 2'-deoxyuridine to uracil and ribose 1-phosphate or 2'-deoxyribose 1-phosphate. This enzyme belongs to the nucleoside phosphorylase I superfamily whose members show diverse specificity for nucleoside substrates. Phylogenetic analysis shows Streptococcus pyogenes uridine

The aim of this study was to describe changes over time in the indications and outcomes of cataract surgery and to discuss optimal timing for the surgery.

In this article, we present the second case of a tongue carcinoma with distinct morphological similarities to a primary sclerosing sweat duct carcinoma of the skin. The tumor infiltrated deeply into the striated muscle and exhibited extensive peri- and intraneural growth. Neoplastic cells had mildly pleomorphic nuclei and displayed in addition to small cysts, distinct duct formation with a bilayer

Escherichia coli 83972 is a clinical asymptomatia bacteriuric isolate that is able to colonize the human urinary bladder without inducing an immune response. Here we demonstrate that one of the mechanisms by which this strain has become attenuated is through the mutation of its genes encoding type I and P fimbriae.

Endo-@b-1,4-d-mannanases (@b-mannanase; EC 3.2.1.78) are endohydrolases that participate in the degradation of hemicellulose, which is closely associated with cellulose in plant cell walls. The @b-mannanase from Trichoderma reesei (Man5A) is composed of an N-terminal catalytic module and a C-terminal carbohydrate-binding module (CBM). In order to study the properties of the CBM, a construct encodi

Hypertension has been associated with raised plasma levels of complement factor 3 and 4 (C3 and C4). The nature of this association is unclear. This population-based longitudinal study explored whether C3 or C4 is associated with development of hypertension. Blood pressure and plasma levels of C3 and C4 were determined in 2178 healthy men, aged 35-50 years, initially without treatment for hyperten

Ammoxidation of 3-picoline to nicotinonitrile was studied on V2O5, V6O13, and V2O4 catalysts in a fixed-bed integral reactor. The activity studies showed that V6O13 was the most active and selective catalyst of the pure oxides, with a maximum yield of 76% nicotinonitrile at 365 °C. The maximum yield on V2O5 catalyst was 34%, and was obtained at a higher temperature, 458 °C. V2O4 was found to be in

Three different least-squares methods for processing time-series of satellite sensor data are presented. The first method uses local polynomial functions and can be classified as an adaptive Savitzky-Golay filter. The other two methods are more clear cut least-squares methods, where data are fit to a basis of harmonic functions and asymmetric Gaussian functions, respectively. The methods incorpora

This study investigated the ward atmosphere of a psychiatric work rehabilitation unit and its relationships to clients' satisfaction with the unit and client motivation, operationalised as proneness to set personal goals for their rehabilitation. The Community-oriented Programs Environment Scale was used and 52 clients participated. Their report of the ward atmosphere was in accordance with recomm

In order for ethanol to be competitive with gasoline, the production cost of ethanol must be lower than it is today. One economically crucial step in the production of ethanol from lignocellulosics is refining, since hydrolysis yields dilute glucose solutions which, after fermentation, result in a dilute ethanol solution, 2-3 wt-% ethanol. A technical-economic investigation of various energy-savin

While researchers have explored the relationship between customer orientation and innovativeness with business performance in different organisations, such studies in small-sized service retailers are scarce. This study investigates potential influences of these two variables on small-sized service retailer performance. Data for this study were collected through personal interviews from 174 Swiss

Background and Purpose - Depression after stroke is often described as underdiagnosed and undertreated. However, there are few data on self-reported depression and use of antidepressants in stroke patients at large. Materials and Methods - In the Swedish national quality assessment register, Riks-Stroke, 15 747 stroke survivors are recorded. They were asked about depressive mood and antidepressant

Strain BOL13 was selected from 18 fungal strains isolated from an oil-spill contaminated site in Oruro, Bolivia. It was identified as a basidiomycete with high homology to Bjerkandera. The fungus degraded 100 mg phenanthrene l(-1) at 0.17 mg l(-1) d(-1) at 30 degrees C at pH 7. During phenanthrene degradation, a maximum manganese peroxidase activity of 100-120 U l(-1) was measured after 10 days of

An experimental and numerical study on mechanical properties, such as strength, elastic modulus, creep and shrinkage, of Self-Compacting Concrete, SCC, and the corresponding properties of Normal Compacting concrete, NC, is outlined in this article. The study included eight mix proportions of sealed or air-cured specimens with water-binder ratio, w/b, varying between 0.24 and 0.80. Half of the mixe
