Steroid hydroxylation using immobilized spores of Curvularia lunata germinated in situ

Spores of Curvularia lunata were immobilized in polyacrylamide granules and in calcium alginate beads (2–3 mm in diam.). Germination of the spores, initiated by the addition of nutrients, resulted in an even distribution of mycelium throughout the beads after 48 h. Such beads were used for the conversion of cortexolone to cortisol by steroid-11β-hydroxylation. In order to improve the steroid trans

Electrochemical Regeneration of NAD Covalently Bound to Liver Alcohol Dehydrogenase

An enzyme-coenzyme complex was immobilized on the surface of a glassy carbon electrode and investigated with cyclic voltammetry in ethanol-containing buffers. The complex consists of an Liver Alcohol Dehydrogenase molecule to which an NAD-analogue is covalently attached via its straight six-carbon, spacer. One cycle was observed but repeated recycling could not be carried out. presumably due to ca

Steroid transformation by living cells immobilized in calcium alginate

Whole cells of Arthrobacter simplex were immobilized in a living state in calcium alginate gel. The bacteria showed steroid-Δ1-dehydrogenase activity and the production of prednisolone from cortisol was investigated. The Δ1-dehydrogenase activity of the immobilized cells could be increased about ten-fold by incubation in nutrient media (e.g., containing 0.5% peptone abd 0.2% glucose). The reason f

The facsimile of The Rudiments or Principles of the German flute : the first English translation of Principes de la Flute Traversiere ou Flute d’Allemagne (1707) by Jacques Hotteterre Le Romain

The present facsimile of The Rudiments or Principles of the German flute (1729)—now republished for the first time since 1729—is a separate supplement to the comparativestudy Les Traditions en Mouvement Principes de la Flute Traversiere ou Flute d’Allemagne (1707) by Jacques Hotteterre Le Romain and The Rudiments or Principles of the German flute (1729) the first English translation of Hotteterre’

Alcohol production by magnetic immobilized yeast

Saccharomyces cerevisiae was immobilized in calcium alginate gel together with varying concentrations of iron oxide, in the form of magnetite or a colloidal ferrite suspension, Ferrofluid™. Inclusion of magnetic material apparently had no adverse effect on the yeast cells as judged from their fermentation capacity, their operational stability as well as their ability to propagatein situ in the pre

Affinity Precipitation of Enzymes

This paper describes the preparation of a bifunctional NAD compound (Bis-NAD) and its properties as a complexing/precipitating agent for the tetrameric enzyme lactate dehydrogenase (LDH).

Universal design : visualising diversity, two low hanging fruits

To plan, design and build with diversity in mind is a complex process. While goals such as inclusion, participation and social sustainability may be present in the vision for a future product, service or environment, studies show that the initial vision isn’t always realized in the end result. There are still far too many products, services and environments that are hard to access or use for parts

The reading practices of people with neuropsychiatric disabilities : A review of library and information science literature

Introduction. The ability to read and interpret different types of text can be significantly impacted by neuropsychiatric disabilities, which affect cognitive abilities. This paper explores and reviews previous studies within library and information science on neuropsychiatric disabilities in relation to reading practices. Method. Searches were performed in LISA and LISTA to identify research on rIntroduction.

Steroid transformation by activated living immobilized Arthrobacter simplex cells

A preparation of living Arthrobacter simplex cells immobilized in polyacrylamide gel, which showed steroid-Δ1-dehydrogenase activity, was studied. The entrapped microorganisms catalyzed the transformation of cortisol to prednisolone and this reaction was followed spectrophotometrically or with the aid of thin layer chromatography (TLC) and high pressure liquid chromatography (HPLC). About 40% of t

Quality of life in patients with resectable rectal cancer during the first 24 months following diagnosis

Aim: An increasing number of patients survive rectal cancer, resulting in more patients living with the side-effects of the treatment. Exploring quality of life before and after treatment enables follow-up and additional treatment to be adjusted to the patient's needs. The aim of the study was to describe the quality of life during the 24 months following diagnosis and to identify risk factors for

Preoperative Group Consultation Prior to Surgery for Colorectal Cancer—an Explorative Study of a New Patient Education Method

Abstract: Patients with colorectal cancer may lack information about the disease and treatment. In 2017, a group consultation before start of surgery was introduced at a university hospital in western Sweden to inform about the disease, treatment, and ongoing scientific studies. The primary aim of this study was to explore the experience of the patients attending the group consultation. Based on s
