  1. 1. Point-of-care beta-hydroxybutyrate determination for the management of diabetic ketoacidosis based on flexible laser-induced graphene electrode system

    University essay from Linköpings universitet/Sensor- och aktuatorsystem

    Author : Simon Andersson; [2021]
    Keywords : Biosensor; Hydroxybutyrate; Point-of-care; Electrochemical; Enzyme; HB; HBD; Dehydrogenase; Ketosis; Ketones; Diabetes; Immobilisation; Chitosan; Gluteraldehyde; PVB; NADH; NAD ; eHealth; Toluidine blue; Cyclic Voltammetry; Amperometry; Potentiometry; Electro Chemistry; BSA;

    Abstract : Diabetic ketoacidosis (DKA) is a life-threatening condition that can appear in patients with diabetes. High ketones in the blood lead to acidity of the blood. For DKA diagnosis and management, ketones such as hydroxybutyrate (HB) can be used to quantify the severity of the disease. READ MORE

  3. 2. Metabolic engineering of Escherichia coli for direct production of 4-hydroxybutyrate from glucose

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

  4. 3. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Mikaela Würtz; [2019]
    Keywords : dairy cattle; drought; energy balance; feeding; metabolism;

    Abstract : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. READ MORE

  5. 4. Thermal Stabilization of Polyhydroxyalkanoates by Washing with Acid

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Emma Welinder; Johanna Nilsson; [2017]
    Keywords : polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : The main goal of this project was to investigate how the thermal stability of two different types of polyhydroxyalkanoates; poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) were affected when washing them with acid solution. Initially, four different acids were used: citric acid, hydrochloric acid, formic acid and acetic acid. READ MORE

  6. 5. Utvärdering av snabbtest för ketonkroppsdetektion hos mjölkkor

    University essay from SLU/Dept. of Clinical Sciences

    Author : Carin Olsson; [2012]
    Keywords : utvärdering; ketonkroppar; snabbtest; mjölkkor; blod; mjölk; urin; ketonkroppar; snabbtest; mjölkkor; blod; urin;

    Abstract : För att en mjölkko ska vara vid god hälsa och producera optimalt är det viktigt att hennes energimetabolism är i god balans. Förhöjda nivåer av ketonkroppar (β-hydroxybutyrat, acetoacetat och aceton) är en indikation på att störningar i energibalansen föreligger och har i flera studier kopplats samman med ökad risk för sjukdomar och sänkt mjölkproduktion.
