  1. 1. An Overview Of The Antibiotic Resistance Mechanisms Of Common Gram Positive And Gram Negative Multidrug Resistant Bacteria

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Elisabeth Tammi; [2023]
    Keywords : Antibiotic resistance mechanism; gram negative bacteria; gram positive bacteria;

    Abstract : Antibiotic resistance in multidrug resistant bacteria cause high mortality rates worldwide, where there has been over 1,000,000 deaths reported as of the year 2019. Antibiotics were thought to be the cure for fighting infectious diseases and preventing further spreading of infection. READ MORE

  3. 2. Design and production of adeno-associated virus vectors for imaging mitochondrial networks in the brain

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Elnaz Samadian Zad; [2023]
    Keywords : adeno-associated virus; mitochondria; mitochondrial networks; imaging; fluorescent protein; synapsin promoter; human embryonic kidney cells; organoids;

    Abstract : Mitochondria are dynamic organelles that function in a complex interconnected network within the cell. Neurons are sensitive and highly energy demanding cells in the brain which require a functioning mitochondrial network that is able to provide ATP and modulate calcium. READ MORE

  4. 3. Permeation studies of Niacinamide and its effect on human skin

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

    Author : Andebrhan Fsahaye; [2023]
    Keywords : niacinamide; permeation; human skin; impedance; hydration;

    Abstract :  Background: Niacinamide (NIA) is one of the most commonly used cosmetic ingredients. It belongs to the vitamin-B3 family and has extensive dermatological therapeutic benefits. NIA has been proven to be a useful skincare product in serving as anti-acne agent, preventing skin hyperpigmentation, removal of wrinkles from the face etc. READ MORE

  5. 4. Diffusion-Based MR Methods for Measuring Water Exchange

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Shan Cai; [2022]
    Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

    Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE

  6. 5. 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
