The enzymes needed for galactomannan hydrolysis, i.e. β-mannanase, α-galactosidase and β-mannosidase, were produced by the filamentous fungus Aspergillus niger. The β-mannanase was purified to electrophoretic homogeneity in three steps using ammonium sulfate precipitation, anion-exchange chromatography and gel filtration. The purified enzyme had an isoelectric point of 3.7 and a molecular mass of
OBJECTIVE: To investigate whether women who made an early sexual debut differ from those with a later debut regarding genital signs and symptoms. METHODS: The study included women who considered themselves gynecologically healthy and who attended 17 family planning centers in 13 European countries for contraceptive advice. There were 629 women who made their sexual debut at the age of 16 years or
We show that the convergence behavior of the many-body numerical diagonalization scheme for strongly interacting bosons in a trap can be significantly improved by the Lee-Suzuki method adapted from nuclear physics: One can construct an effective interaction that acts in a space much smaller than the original Hilbert space. In particular for short-ranged forces and strong correlations, the method o
The Quaternary sedimentary succession in Vendsyssel, northern Denmark, contains a unique, high-resolution record of the last interglacial and glacial periods. There is still much debate, however, about the timing and ice extent in this southwestern part of the Scandinavian Ice Sheet, particularly during the Middle Weichselian. In this study, a detailed lithostratigraphical subdivision is establish
STUDY OBJECTIVE: Although national variation in short-term prognosis (that is, 30 day mortality) after a patients first hospitalisation for heart failure may depend on individual differences between patients, dissimilarities in hospital practices may also influence prognosis. This study, therefore, sought to disentangle patient determinants from institutional factors that might explain such variat
A study of modified carbon paste electrode employing Nile blue (NB) adsorbed on silica gel modified with niobium oxide (SN) for electrocatalytic oxidation of reduced nicotinamide adenine dinucleotide (NADH) is described. The adsorbed organic dye on SN was used to prepare a modified carbon paste electrode to investigate its electrochemical properties. The formal potential (E-o') of the adsorbed NB
The 80+ Studies are collecting longitudinal data regarding medical, psychological, and sociological aspects of 80-year-old people in Lund, Sweden and Reykjavik, Iceland. Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher
Aim. This paper is a report of a study to elucidate families' lived experience of diabetes one year after a child was diagnosed with type 1 diabetes. Background. The incidence of type 1 diabetes is rapidly increasing worldwide, with a shift towards younger age groups. This illness is treated by means of an intensive management regimen that often disrupts the child's usual activities and requires d
Let $(A,^-):={\cal M}(J)$ be the $2 \times 2$-matrix algebra determined by Jordan algebra $J:=H_3(\mathbb{A})$ of hermitian $3 \times 3$-matrices over a real composition algebra $\mathbb{A}$, where $(A,^-)$ is the standard involution on $A$. We show that the triple systems $B_A(x,\overline{y}^\sim,z), x,y,z\in\mathbb{A}$, are models of simple compact Kantor triple systems satisfying the condition
Exact and approximate quantum numbers of the cranked Nilsson-Strutinsky (CNS) formalism are exploited to calculate excited bands in fixed configurations with the energy of the individual bands minimized with respect to deformation for all spin values. The formalism is illustrated to calculate all bands which appear important in the decay out of the superdeformed band in 59Cu

PURPOSE: As a prelude to developing updated, evidence-based, international consensus recommendations for the management of hip and knee osteoarthritis (OA), the Osteoarthritis Research Society International (OARSI) Treatment Guidelines Committee undertook a critical appraisal of published guidelines and a systematic review (SR) of more recent evidence for relevant therapies. METHODS: Sixteen exper
To clarify the role of metabolic factors in endometrial carcinogenesis, we conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), and examined the relation between prediagnostic plasma lipids, lipoproteins, and glucose, the metabolic syndrome (MetS; a cluster of metabolic factors) and endometrial cancer risk. Among pre- and postmenopau
Force feedback control is necessary for accurate force control in robotic manipulators and, thus far, wrist force/torque (F/T) sensors have been used. An important problem arises when only these types of sensors are used. In a dynamic situation where the manipulator moves in either free or constrained space, the interaction forces and moments at the contact point and also the non-contact ones are
The quality of cervical histopathology is critical to cervical cancer prevention, cancer treatment, and research programs. On the basis of the histology results further patient management is determined. However, the diagnostic interpretation of histologic hematoxylin-eosin (H&E)-stained slides is affected by substantial rates of discordance among pathologists. Overexpression of the cyclin-depe
Objective: To describe the phenotype of the Bardet-Biedl syndrome in patients with mutations in the BBS4 gene. Methods: We examined 3 pairs of siblings with Bardet-Biedl syndrome in whom 3 different mutations in the BBS4 gene were detected, 2 of which were homozygous for the mutation. Results: All patients had an increased body mass index. The obesity varied between families from moderate to sever
1. Ten south Swedish streams were selected to represent two distinct types - natural woodland streams and channelized streams. Measurements were made on leaching, decomposition and microbial respiration of the dominant riparian vegetation (European Black Alder), structure of the benthic macroinvertebrate community, macroinvertebrates inhabiting leaf material, channel morphometry, macrophyte compos
