Simultaneous enzymatic wheat starch saccharification and fermentation to lactic acid by Lactococcus lactis

Simultaneous saccharification of starch from whole-wheat flour and fermentation to lactic acid (SSF) was investigated. For saccharification the commercial enzyme mixture SAN Super 240 L, having alpha-amylase, amyloglucosidase and protease activity, was used, and Lactococcus lactis ssp. lactis ATCC 19435 was used for the fermentation. SSF was studied at flour concentrations corresponding to starch

Genetic Effects on Women's Positive Mental Health: Do Marital Relationships and Social Support Matter?

Interpersonal relationships are important factors in mental health. A genetically sensitive design was used to examine associations among marital quality, adequacy of social support, and 2 aspects of positive mental health in a sample of 652 Swedish twin women and their families. There were 3 main findings. First, the covariance between relationships and positive mental health was partially accoun

Molecular dynamics simulation of the effects of cytosine methylation on structure of oligonucleotides

Methylation of the cytosine bases in CpG dinucleotides of DNA is important in many cellular functions including gene regulation, chromosome inactivation, as well as in cancer and other diseases. In this report we investigate the structural effects of methylation of cytosines in CpG sites. Hereditary diseases are frequently caused by mutations in CpG dinucleotides. Aqueous solution molecular dynami

Män, kvinnor & omsorg : En studie av omsorg som begrepp och handling i mans- och kvinnodominerade yrken

Syftet med denna avhandling var att undersöka omsorg som begrepp och handling och att se hur omsorg kan yttra sig under olika villkor. Avhandling innehåller en översikt över icke-feministiska och feministiska teorier och filosofier om omsorg samt en empirisk undersökning av uppfattningar om omsorg och omsorgshandlingar i fyra yrkesgrupper: fastighetsansvariga, kvarterspoliser, distriktssjukskötersThe aim of this study was to investigate care as concept and action and to see how care can be expressed in different conditions. The dissertation contains a survey of non-feminist and feminist theories of care and an empirical study of views of care and caring acts in four professional groups: janitors, neighbourhood police, district nurses, and home-helpers. The study, which is based on intervie

LEPREL1, a novel ER and Golgi resident member of the Leprecan family.

We have identified a novel protein, Leprecan-like 1 (LEPREL1), with profound similarity to the Leprecan family of proteoglycans. The genomic organization of the Leprecan gene family was found to be highly conserved. Expression analysis shows that LEPREL1 is expressed in most tissues as a 3.4 kb transcript encoding an 80 kDa protein. A LEPREL1 specific antibody stains many cell types including adip

Left atrioventricular plane displacement determined by echocardiography: a clinically useful, independent predictor of mortality in patients with stable coronary artery disease

Background. Echocardiographically determined left atrioventricular plane displacement (AVPD) is strongly related to prognosis in patients with chronic heart failure and in postmyocardial infarction patients. We aimed at exploring whether AVPD, unlike ejection fraction, is related to mortality in patients with stable coronary artery disease (CAD). Methods and results. Atrioventricular plane displac

Determination of atmospheric trace gas amounts and corresponding natural isotopic ratios by means of ground-based FTIR spectroscopy in the high Arctic

Abstract In the given report, scientific results gathered at the Alfred- Wegener- Institut für Polar- und Meeresforschung (AWI) within an ScD contract are summarized. The AWI is the German large scale research facility for polar- and marine research. In January 1992 +he new research de- partment at Potsdam has been established with the section Physics und Chemistry of the Atmosphere. 1t coordinate

A high-resolution FT-IR study of the fundamental bands nu(6), nu(10), and nu(11) of trans-glyoxal

The high-resolution Fourier transform infrared spectrum of trans-glyoxal in the gas phase has been recorded in the spectral regions 700-900 cm(-1), 1200-1400 cm(-1), and 1600-1800 cm(-1) with a resolution ranging from 0.0020 to 0.0025 cm(-1). The spectrum displays extensive rotational structures which are assigned to the three fundamental bands upsilon(6) (A(u), 801.5 cm(-1)), upsilon(10) (B-u, 17

A New Approach for Determination of the Selectively Favoured Kinetic Design of Enzyme Reactions

A new criterion is applied for characterization of the kinetic design of enzymes that should be favoured by a selective pressure in the direction of increased metabolic reaction flux. According to this criterion, the selectively favoured state of a metabolic sequence of enzyme reactions conforming to Michaelis-Menten kinetics is identical with the uniform one which is known to optimize reaction fl

Approximation algorithms for Hamming clustering problems

We study Hamming versions of two classical clustering problems. The Hamming radius p-clustering problem (HRC) for a set S of k binary strings, each of length n, is to find p binary strings of length n that minimize the maximum Hamming distance between a string in S and the closest of the p strings; this minimum value is termed the p-radius of S and is denoted by varrho. The related Hamming diamete
