Estimation of conversion factors for fungal biomass determination in compost using ergosterol and PLFA 18 : 2 omega 6,9

Eleven species of common fungi from compost were analysed for their content of ergosterol and phospholipid fatty acids (PLFAs) after growth on agar media. Mean content of ergosterol was 3.1 mg g(-1) dw of fungal mycelium (range 1-24 mg g(-1) dw). Total amount of PLFAs varied between 2.6 and 43.5 mumol g(-1) dw of fungi (mean 14.9 mumol g(-1) dw). The most common PLFAs were 16:0,18:2omega6,9 and 18

Multiple factors affect the loss of measurable C-peptide over 6 years in newly diagnosed 15- to 35-year-old diabetic subjects

Objective: The aim of this study is to identify risk factors for the loss of measurable plasma C-peptide in newly diagnosed 15- to 35-year-old diabetic subjects. Methods: This Swedish study included 778 subjects. C-peptide levels were obtained each year for 6 years after diagnosis. Loss of measurable C-peptide was defined as a level at or below the lower detection limit of the local assay (0.13 nm

Det personliga äktenskapet : ett exempel ur medeltida litteratur

Abstract in FrenchCet article a pour cadre le développement de l'idée du mariage comme une union personnelle se fondant sur la relation entre les époux. Les théories qui se sont développées à partis du XIe siècle à l'intérieur de l'église ont mis l'accent sur le caractère personnel du mariage: le fondement du sacrement du mariage étant devenu l'union entre deux individus et non pas l'interêt familIn this article I examine the development of the idea of marriage as a personal union whose foundation is the relation between the spouses. The theories which developed within the Church from the eleventh century and onwards put the emphasis on the personal side of marriage; the sacrament of marriage was founded on the union between the spouses and not on family interest. From the middle of the tw

Optically induced charge storage and current generation in InAs quantum dots

We report on optically induced charge storage effects and cur-rent generation in self-assembled InAs quantum dots embedded in an InP matrix. Illumination with photons of energy higher than about 0.86 eV efficiently loads the dots with a maximum of about 1 hole/dot. The spectral response at lower photon energy is strongly enhanced at elevated temperatures. We present a detailed balance model for th

Äldre och design

Hur vi ser på teknik hänger ihop med hur vi ser på människan. Forskningen inom området Äldre och design i Lund har en uttalad avsikt: att människor med funktionsnedsättningar ska få bättre förutsättningar. Arbetet börjar och slutar i människan. Seniorer på egna villkor, Bodil Jönsson Design för funktion, Bodil Jönsson Titta på tv – ett sätt att kommunicera, Britt Östlund Design för den mänskli

Relations between elemental content in till, mineralogy of till and bedrock mineralogy in the province of Småland, southern Sweden

Information on soil mineralogy is essential for weathering rate calculations. Quantitative mineralogical analyses are expensive and time-consuming, and thus indirect methods of determining the mineralogical composition are important, for example estimating the composition based on the elemental content in till (total concentrations), or based on information about the underlying bedrock. The minera

Laser spectroscopy of gas in scattering media at scales ranging from kilometers to millimeters

Free gases are characterized by their narrow line width, and they can conveniently be studied by laser spectroscopy. The present paper discusses the monitoring of such ambient pressure gases, which are dispersed in scattering media such as aerosol-laden atmospheres, solids, or liquids. Atmospheric work basically constitutes the well-known field of differential absorption lidar (DIAL), while the st

Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. Fracture models and strength relations are discussed also from a few more general and fundamental points of view. A number of comparisons a

Gene therapy for Parkinson's disease.

The once fantastic theoretical concept that patients with Parkinson's disease (PD) would receive gene therapy in an attempt to alleviate their symptoms and potentially modify the course of their disease has become a reality. On the basis of positive preclinical data, four different gene therapy approaches are currently in Phase I or Phase II clinical trials. Some approaches are intended to increas

The Experience of Care at Nurse-Led Rheumatology Clinics.

OBJECTIVE: To describe how people with rheumatoid arthritis (RA) experience the care provided by Swedish nurse-led rheumatology outpatient clinics. METHODS: Eighteen adult people with a diagnosis of RA who had had at least three documented contact sessions with a nurse-led clinic were interviewed. The interviews were analysed with qualitative content analysis. RESULTS: Care was expressed in

Fibroblast growth factor 8 increases breast cancer cell growth by promoting cell cycle progression and by protecting against cell death.

Fibroblast growth factor 8 (FGF-8) is expressed in a large proportion of breast cancers, whereas its level in normal mammary gland epithelium is low. Previous studies have shown that FGF-8b stimulates breast cancer cell growth in vitro and in vivo. To explore the mechanisms by which FGF-8b promotes growth, we studied its effects on cell cycle regulatory proteins and signalling pathways in mouse S1

Cerebellar Synaptic Plasticity and the Credit Assignment Problem.

The mechanism by which a learnt synaptic weight change can contribute to learning or adaptation of brain function is a type of credit assignment problem, which is a key issue for many parts of the brain. In the cerebellum, detailed knowledge not only of the local circuitry connectivity but also of the topography of different sources of afferent/external information makes this problem particularly

A Method for Arterial Diameter Change Measurements Using Ultrasonic B-Mode Data.

Arterial diameter change is related to distending blood pressure and is used in estimation of arterial stiffness parameters. A common technique to track the arterial walls is by integration of wall velocities estimated by different methods using cross correlation or tissue Doppler. However, because of the high pulse repetition frequency and the need for separate pulsing sequences, the B-mode image

High hyperdiploid childhood acute lymphoblastic leukemia.

High hyperdiploidy (51-67 chromosomes) is the most common cytogenetic abnormality pattern in childhood B-cell precursor acute lymphoblastic leukemia (ALL), occurring in 25-30% of such cases. High hyperdiploid ALL is characterized cytogenetically by a nonrandom gain of chromosomes X, 4, 6, 10, 14, 17, 18, and 21 and clinically by a favorable prognosis. Despite the high frequency of this karyotypic
