The present invention relates to a method of extg. 3-hydroxypropionaldehyde (3-HPA) and/or derivs. thereof from an aq. soln. comprising 3-HPA. This method comprises (a) contacting the aq. soln. comprising 3-HPA with chitosan and/or chitosan comprising polymers, (b) sepg. the 3-HPA bound chitosan and/or chitosan comprising polymers, and (c) washing the 3-HPA bound chitosan and/or chitosan
Ever since its introduction 40 years ago l-3,4-dihydroxyphenylalanine (l-DOPA) therapy has retained its role as the leading standard medication for patients with Parkinson's disease. With time, however, the shortcomings of oral l-DOPA treatment have become apparent, particularly the motor fluctuations and troublesome dyskinetic side effects. These side effects, which are caused by the excessive sw
We are constantly exposed to infectious diseases, and they cause millions of deaths per year. TheWorld Health Organization (WHO) estimates that antibiotic resistance could cause 10 million deaths per year by 2050. Multidrug-resistant bacteria are the cause of infection in at least one in three people suffering from septicemia. While antibiotics are powerful agents against infectious diseases, the
Objectives: We conducted a large cohort study to investigate the association between work-related wrist movements and carpal tunnel syndrome (CTS). Methods: Electro-goniometric measurements of wrist movements were performed for 30 jobs (eg, office work, child care, laundry work and slaughterhouse work). We measured wrist angular velocity, mean power frequency (MPF) and range of motion (ROM). We es
Reliable wireless communication links are a critical but challenging aspect for high-speed railway (HSR). To develop and analyze such systems, accurate models for the propagation channel are required. The radio channel properties in HSR scenarios are different from those in cellular scenarios not only due to the high velocity, but also due to the special construction elements and the type of surro
Background: Studies of survival comparing radical cystectomy (RC) and radiotherapy for muscle-invasive bladder cancer have provided inconsistent results and have methodological limitations. The aim of the study was to investigate risk of death after radiotherapy as compared to RC. Methods: We selected patients with muscle-invasive urothelial carcinoma without distant metastases, treated with radio
Objectives: To investigate survival among elderly residents of Swedish nursing homes (NHs), with specific focus on those with two or more signs of Lewy body dementia (LBD). Design: Prospective observational study. Setting: NHs in Malmö, the third largest city in Sweden. Participants: The study population was older adults (aged ≥65 years) living in the 40 NHs in Malmö. Clinical data were collected
Background:Continuous flow peritoneal dialysis (CFPD) is performed using a continuous flux of dialysis fluid via double or dual-lumen PD catheters, allowing a higher dialysate flow rate (DFR) than conventional treatments. While small clinical studies have revealed greatly improved clearances using CFPD, the inability to predict ultrafiltration (UF) may confer a risk of potentially harmful overfill
