Prior to binding to antigenic peptide, the major histoconipatibility complex (MHC) heavy chain associates with an assembly complex of proteins that includes calreticulin, tapasin, and the transporter associated with antigen processing (TAP). Our data show that calreticulin can bind weakly to L-d without tapasin's assistance, and that deglycosylation of the alpha1 domain results in a primary loss o
The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection for benign hyperplasia or cancer of the prostate and compared with that of controls without antibiotic (Group III). Both regiments significantly reduced the frequency of postoperative bacteriuria (p less than 0.01) and of severe infectious com
The variations in functional capacity, life quality and health increase as people grow older. Most likely, this is the result of a lifelong process in which both "wear-and-tear" and constructive development play a major role. Life experiences all the way from daily hazards to burdensome life events, to long-term exposure, to stress and strain might wear out the body. Life experiences of self-fulfi
A consecutive population-based series of 372 adult acute myeloid leukemias, successfully cytogenetically investigated at a single center between 1976 and 1993, is reported. All medical records were reviewed in order to ascertain the prognostic impact of karyotype, divided into three groups; favorable (t(8;21), t(15;17), and inv(16) irrespective of karyotypic complexity; n = 40), poor (der(1;7), in
Water demand for manual fire suppression is analyzed. The Fire Point Theory is validated concerning fuel surface cooling effects and the critical water flow rate is determined and compared with previous investigations. It is shown that the critical flow rate is not the best use of resources. Therefore, the water flow giving the minimum total volume is determined. Data from real fires was compared
A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled hexahydrophthalic acid was used as the internal standard. The precisi
DNA-cationic liposome complexes as possible vehicles for gene delivery is currently an important issue. In this work, the interaction between DNA and thermodynamically stable, spontaneously formed, catanionic vesicles with a net positive charge is studied. A phase map was drawn for the aqueous system of DNA and positively charged vesicles, composed of CTAB (cetyltrimethylammonium bromide) and SOS
Staining by activating transcription factor 3 (ATF3), a neuronal marker of nerve injury, was examined by immunocytochemistry in neurons and Schwann cells after crush or transection (regeneration inhibited) of rat sciatic nerve. ATF3 immunoreactivity peaked in neurons after three days and then gradually subsided to normal within 12 weeks after the crush. The response lasted somewhat longer and decl
BACKGROUND: The host response to urinary tract infection includes the production of different inflammatory mediators. We investigated the cellular localization and time course of inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) expression in the mouse bladder and kidney after bacterial infection. METHODS: Experimental urinary tract infection in mice was established by intravesical

Traumatic brain injury (TBI) has long-lasting consequences not only for the individual with the injury but also for family members. The aim of this study is to elucidate the meaning of family members' experiences of living with an individual with moderate or severe TBI. The data have been collected by means of qualitative research interviews with 8 family member participants. A phenomenological he
Barn med cerebral pares (CP) riskerar att utveckla höstfluxation, kontrakturer och skolios. Genom att registrera och följa barnen på ett standardiserat sätt, och vid behov ge förebyggande behandling, kan komplikationerna förhindras i stort utsträckning.
t This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the
A system for ion beam tomography has been implemented in conjunction with the new sub-micron bearriline at the Lund Nuclear Microprobe laboratory. The first version of the system is dedicated to STIM (scanning transmission ion microscopy) tomography for three-dimensional mass density analysis, but future development will allow also PIXE (particle induced X-ray emission) tomography for elemental an
In this review we discuss the influence of chaperones on the general phenomena of folding as well as on the specific folding of an individual protein, MHC class I. MHC class I maturation is a highly sophisticated process in which the folding machinery of the endoplasmic reticulum (ER) is heavily involved. Understanding the MHC class I maturation per se is important since peptides loaded onto MHC c
Enzymatic hydrolysis is an agro-processing aid that can be utilized in order to improve nutritional quality of protein extracts from many sources. In this study, protein extracts from ungerminated and/or germinated local Egyptian soybean and lupin flours were hydrolyzed using the enzyme papain. The hydrolysis processes were carried out for 2 h and aliquots were withdrawn at different time interval
