- An outline is presented here of the Po Valley Fog Experiment 1989, carried out within the EUROTRAC‐GCE project. This experiment is a joint effort by several European research groups from 5 countries. The physical and chemical behaviour of the fog multiphase system was studied experimentally following the temporal evolution of the relevant chemical species in the different phases (gas, droplet, interstitial aerosol) and the evolution of micrometeorological and microphysical conditions, from the pre‐fog situation through the whole fog evolution, to the post‐fog period. Some general results, useful for describing the general features of the fog system, are presented here, while specific scientific questions on the different processes taking place within the system itself will be addressed in other companion papers of this same issue.

- Staphylococcus saprophyticus commonly causes urinary tract infection (UTI) in young women; in males it is found mainly in the elderly. In this study S. saprophyticus UTI occurred in 59 children (45 girls and 14 boys) below 16 years of age, of whom 20 were less than 13 years of age. The common presentation was dysuria and flank or back pain whereas fever > or = 38.5 degrees C was rare. Radiological investigation performed in 63% of the children revealed no anomalies of importance. Children with S. saprophyticus UTI appear to constitute a group with a low frequency of urinary tract anomalies and with a low risk of UTI caused by other bacteria.

Peri- and postoperative changes in serum levels of four tumor markers and three acute phase reactants in benign and malignant gynecological diseases.

- Serum levels of squamous cell carcinoma antigen, carcinoembryonic antigen, CA 125, tissue polypeptide antigen, CRP, alpha 1-antitrypsin and haptoglobin were determined peri- and postoperatively in patients undergoing surgery for benign gynecological disease (n = 18) and postoperatively in women operated for cervical carcinoma (n = 23). The only significant changes seen after premedication, during anesthesia and during surgery were a decrease in serum concentrations of alpha 1-antitrypsin and haptoglobin. We found no postoperative changes in the serum levels of squamous cell carcinoma antigen nor in carcinoembryonic antigen values. However, the latter analyte was influenced by smoking habits. Elevated levels of CA 125 and tissue polypeptide antigen were found in the cancer patients, predominantly within the first 1-3 weeks after surgery. These levels decreased to normal values within 4-6 weeks postoperatively. The median intraindividual coefficients of variation for the tumor markers ranged between 15% and 28% in 30 control women not having surgery. In general, it would seem advisable to wait 6 weeks after surgery before monitoring with CA 125 and TPA is started.

- A cDNA encoding kappa-casein of human milk was cloned and sequenced. The kappa-casein cDNA was isolated from a lambda gt11 library generated from mRNA prepared from a mammary gland biopsy obtained from a lactating woman. The library was screened with polyclonal rabbit antibodies raised against purified native kappa-casein. The obtained nucleotide sequence contained an ORF sufficient to encode the entire amino acid sequence of a kappa-casein precursor protein consisting of 182 amino acids. This includes a tentative signal peptide of 20 amino acids and a processed protein of 162 amino acids.

- Studies on physiological function and on structure-function relationships of human milk beta-casein have been limited. In this study, we have introduced the human beta-casein cDNA into vectors designed for expression in Escherichia coli. The inducible T7-based expression system resulted in high-level expression of recombinant beta-casein. The recombinant beta-casein, localized intracellularly in E. coli, was purified to homogeneity and compared with purified native beta-casein, in particular with respect to phosphorylation. The E. coli-produced beta-casein was found to comigrate with the full-length, nonphosphorylated native human beta-casein isoform on SDS-PAGE. An N-terminal peptide containing all tentative phosphorylation sites was isolated from the recombinant protein and analyzed by mass spectrometry. The molecular mass as well as the migration of this peptide on reversed-phase chromatography confirmed that it was unphosphorylated.

Ergonomic Evaluation of Two Different Locations of the Scales in a Supermarket Checkout System
- 1993

Ingår i: Advances in Industrial Ergonomics and Safety V. ; , s. 667-674

Konferensbidrag (refereegranskat)abstract
- The aim of this pilot study was to ergonomically evaluate the effect of the location of the scales in a supermarket checkout system. A location of the scales to the left of the cashier was compared with a location under the conveyor belt. Two cashiers were videotaped while working with the two scale locations, in both sitting and standing working postures. Analysis of the video tapes was performed using the WOPALAS method, the VIRA method, and by noting certain positions of the left arm. The left wrist movements were registered by a two-dimensional goniometer. The results indicate that the location under the conveyor belt is somewhat more ergonomically favourable. The improvement is more pronounced for the cashier with a greater reach.

The stability of 5-S-cysteinyldopa and 6-hydroxy-5-methoxyindole-2-carboxylic acid in human urine

Tidskriftsartikel (refereegranskat)abstract
- 5-S-cysteinyldopa and 6-hydroxy-5-methoxyindole-2-carboxylic acid are important intermediate metabolites in the formation of cutaneous melanin pigment. Since they both are serious candidates as markers of melanoma progression, their stability in urine has been investigated during storage at various conditions. The results show that storage at -20 degrees C is necessary. Both compounds are nonstable at room temperature, particularly if the urine was not acidified to pH 4-5. Reference levels were obtained from analysis of urine from 31 men and 40 women. The mean (SD) excretion of 5-S-cysteinyldopa was 32 (12.5) mumol/mol creatinine (women). Corresponding figures for 6H5MI2C were 23 (10.3) and 24 (8.1) mumol/mol creatinine for men and women respectively.
