  1. 1. Relations between intracellular pH and gamma-aminobutyric acid levels in tea (Camellia sinensis) leaves, after two types of anaerobic treatment

    L3-uppsats, SLU/Dept. Of Plant Biology

    Författare :Mingmin Tao; [2023]
    Nyckelord :tea leaves; intracellular pH; gamma-aminobutyric acid; glutamate; decarboxylase; fluorescent dye;

    Sammanfattning : Tea (Camellia sinensis) is one of the three major non-alcoholic beverages in the world. In Gabaron tea, the levels of γ-aminobutyric acid (GABA) are more than 1.3 mg/g. In the human body, GABA lowers blood pressure and cholesterol levels. LÄS MER

  3. 2. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Fredrik Salomon-Sörensen; [2023]
    Nyckelord :Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Sammanfattning : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. LÄS MER

  4. 3. Application of Biomimetic Membrane Models in Expansion Microscopy

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Praghadhesh Thiagarajan; [2023]
    Nyckelord :Fluorescence microscopy; expansion microscopy; GPMV; inter-leaflet asymmetry; Fluorescensmikroskopi; expansionsmikroskopi; GPMV; asymmetri mellan lagren;

    Sammanfattning : Plasmamembranet är en komplex struktur som består av biomolekyler som lipider, proteiner och glykaner. Membranets rena komplexitet begränsar vår förmåga att förstå den spatiotemporala dynamiken hos sådana komponenter och deras kollektiva biofysiska membranparametrar. LÄS MER

  5. 4. Diffusion and Camera-Noise Modelling for Analysis of Single-Particle Tracking Movies

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Erik Clarkson; [2022]
    Nyckelord :reaction-diffusion; camera-noise modelling; single-particle tracking; Gillespie simulations; Physics and Astronomy;

    Sammanfattning : Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. LÄS MER

  7. 5. Improving bright-field images for tracking particles with Defocustracker

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Carl Lundin; [2022]
    Nyckelord :Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. LÄS MER
