  1. 21. Mathematical representation and simulation of an ECMO pump : Focusing on device performance and indications of flow-induced complications

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

    Author : Jonathan Kardelind; [2022]
    Keywords : ECLS; ECMO; CentriMag; Clot detection; Flow restriction detection; Power monitoring; ECLS; ECMO; CentriMag; Proppdetektion; Flödes restriktionsdetektion; effektmätning;

    Abstract : Extracorporeal membrane oxygenation (ECMO) is a medical treatment that aims to support patients' respiratory and circulatory systems by oxygenation of blood outside of the patient. The therapy exposes blood to an artificial environment, which increases the risk of clot formations in the blood. READ MORE

  3. 22. Study of pH effect on the skin in Franz cell by impedance spectroscopy: an attempt to model incontinence effect on the skin.

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Megha Bhavinkumar Patel; [2022]
    Keywords : Artificial urine; Electrical impedance spectroscopy EIS ; Incontinence-associated dermatitis IAD ; pH; Stratum corneum SC ; Artificial urine; Electrical impedance spectroscopy EIS ; Incontinence-associated dermatitis IAD ; pH; Stratum corneum SC ;

    Abstract : The human skin is the largest and most complex body organ but accessible and attractive for biomarker sampling and transdermal drug delivery. The two procedures are significantly impacted by several biophysical properties of the skin, especially the pH and stratum corneum (SC)hydration. READ MORE

  4. 23. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lea Enenkelová; [2021]
    Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

    Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

  5. 24. Leachate-Based Biotic Ligand Model for Soil : Ecotoxicological Risk Assessment of Copper for Invertebrates, Plants, and Soil Microbial Processes

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tove Florén; [2021]
    Keywords : Tomato shoot; Barley root; Glucose induced respiration; Nitrification; Earthworm; Springtail; EC10; SSD; Regression analysis; pH dependency; Bioavailability;

    Abstract : Environmental pollution of heavy metals has become an increasing problem. Environmental risk assessments can be conducted to investigate and determine the potential risk of polluted terrestrial environments. Traditionally, risk assessments are based on total soil metal concentrations on a dry weight basis. READ MORE

  6. 25. The effects of IRAP-inhibitors in the brain

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Dennis Josefsson; [2021]
    Keywords : IRAP; insulin-regulated aminopeptidase; IRAP-inhibitors; memory disorders; neurogenerative diseases; cognitive impairments;

    Abstract : The increased understanding of underlying neurobiological processes and their connections to cognitive performance has opened new doors for novel therapeutic strategies that aim to prevent, and even reverse the effects of memory disorders, neurodegenerative diseases and other cognitive impairments. One of the new and exciting drug targets that has emerged as a result of this research is insulin-regulated aminopeptidase (IRAP). READ MORE
