We have previously reported that the heparan sulfate-priming glycoside 2-(6-hydroxynaphthyl)-ß-D-xylopyranoside selectively inhibits growth of transformed or tumor-derived cells. To investigate the specificity of this xyloside various analogs were synthesized and tested in vitro. Selective growth inhibition was dependent on the presence of a free 6-hydroxyl in the aglycon. Because cells deficient

A novel method has been developed for acquiring the correct alignment of a query sequence against remotely homologous proteins by extracting structural information from profiles of multiple structure alignment. A systematic search algorithm combined with a group of score functions based on sequence information and structural information has been introduced in this procedure. A limited number of to

The entire population of magmatic oscillatory zoned zircons in a migmatitic granite from the Tjarnesjo intrusion, southwest Sweden, reveal fine-scale brittle fracturing. The oscillatory zoned fragments are rotated but not dispersed. Fractures between individual fragments are sealed by newly formed CL-bright zircon. Hydraulic fracturing is the most probable mechanism. The internal structure of frac

Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors difficult. This thesis has applied microarray-based gene expression and copy-number profiling to STS

Purpose: Autonomous bladder activity can take the form of localized micromotions (MMs), suggesting that the detrusor may be arranged into component modules, of which each is capable of contracting autonomously. We examined MMs in isolated whole rat bladder and the effects of partial bladder outlet obstruction as a model of detrusor overactivity (DO) to ascertain whether altered modular activity co

In an investigation by the Swedish Cancer Society, the present status, critical issues and future aspects and potentials in each of nine major areas of radiation therapy research were described by an expert group. The report presented here deals with radiation therapy dose delivery, dose distributions, beam shaping and intensity modulation.

Calnexin (Cnx) has been characterized as a membrane-bound protein that transiently interacts in a unique chaperone system with newly synthesized glycoproteins in order to allow the establishment of their proper tertiary and, in most cases, quarternary structures. The aim of the study was to identify and to locate the expression of Cnx in the three major salivary glands of humans by different metho

Osteoclastic bone resorption depends on the activity of various proteolytic enzymes, in particular those belonging to the group of cysteme protemases. Biochemical studies have shown that cystatins, naturally occurring inhibitors of these enzymes, inhibit bone matrix degradation. Since the mechanism by which cystatins exert this inhibitory effect is not completely resolved yet, we studied the effec

The undamped natural vibrations of a constrained linear structure are given by the solutions to a generalized eigenvalue problem derived from the equations of motion for the constrained system involving Lagrangian multipliers. The eigenvalue problem derived is defined by the mass matrix of the unconstrained structure and a non-symmetric and singular stiffness matrix for the constrained system. The

The report is a short survey of instrumentation and control in wastewater treatment plants in the USA. Primarily biological and chemical wastewater treatment is considered. The report is based partly on personal experiences from the USA, partly on literature studies.

The healthcare sector constitutes a major part of the economy of developed nations and consumes significant quantities of consumables. The Region Scania commissioned IIIEE, Lund University, to develop a management tool for strategic decision-making in order to reduce the climate impact indirectly derived from material, consumption. The tool was streamlined to fit operational conditions at Region S
