  1. 16. From Plant Genetic Resource Conservation to Digital Biorepositories: A Coming Paradigm Shift in Ex-Situ Conservation?

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Christopher Keegan; [2023]
    Keywords : Bioinformatics; Genebanks; Genetic Engineering; Mixed-Methods; Multi-Disciplinary; Patent Analysis; Plant Genetic Resources; Synthetic Biology; Technological Trajectories; Business and Economics;

    Abstract : Plant Genetic Resource Conservation has been a staple of agricultural development for the past century. Recently, several prominent papers have raised alarm surrounding the development of synthetic biology techniques and their potential to render modern practices and methods of conservation in the global genebank network obsolete.

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

    University essay from SLU/Dept. Of Plant Biology

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

    Abstract : 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. READ MORE

  4. 18. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Dolev Illouz; [2023]
    Keywords : super-resolution; alternating descent conditional gradient method; ADCG; multiple-emitter localization; nanoscale imaging; single molecule tracking; Physics and Astronomy;

    Abstract : This thesis examines the state-of-the-art 2D super-resolution technique alternating descent conditional gradient (ADCG) method's ability to accurately localize fluorophores in diffraction-limited single molecule images (SMI) and analyze the impact of pre-processing and post-processing modules on ADCG's fluorophore localization. A synthetic dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their noise parameters.

  5. 19. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Harald Agelii; [2023]
    Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

    Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE

  6. 20. Chromatin accessibility analysis of spaceflight mouse brains using ArchR

    University essay from KTH/Genteknologi

    Author : Raphaël Mauron; [2023]
    Keywords : Single nuclei ATAC-sequencing; Space Biology; DNA Chromatin accessibility; Neurodegenerative; ArchR; ATAC-sekvensering av enskilda kärnor; rymdbiologi; tillgänglighet av DNA kromatin ; neurodegenerativa sjukdomar; ArchR;

    Abstract : Mänsklig utforskning av månen och Mars innebär stora utmaningar för människans fysiologi och hälsa på grund av de unika miljöfaktorer som följer av långvariga rymduppdrag. Rymdbiologiska experiment har blivit ett viktigt verktyg för att studera effekterna som mikrogravitation och rymdstrålning har på levande organismer, i syfte att förstå och minska dessa utmaningar.
