Ligand binding and complex formation of galectin-3 is modulated by pH variations

Galectin-3-dependent clusters or lattices are formed at the surface as well as in distinct organelles of eukaryotic cells. Incorporation into membrane proximal networks can fix glycoproteins within subcellular domains or sort them into distinct transport pathways. In the present paper we analysed the effect of acidification on the sugar binding and self-oligomerization of galectin-3. Using a fluor

Bacterial adhesion of Streptococcus suis to host cells and its inhibition by carbohydrate ligands

Streptococcus suis is a Gram-positive bacterium, which causes sepsis and meningitis in pigs and humans. This review examines the role of known S. suis virulence factors in adhesion and S. suis carbohydrate-based adhesion mechanisms, as well as the inhibition of S. suis adhesion by anti-adhesion compounds in in vitro assays. Carbohydrate-binding specificities of S. suis have been identified, and th

Long-term calcium imaging reveals functional development in hiPSC-derived cultures comparable to human but not rat primary cultures

Models for human brain-oriented research are often established on primary cultures from rodents, which fails to recapitulate cellular specificity and molecular cues of the human brain. Here we investigated whether neuronal cultures derived from human induced pluripotent stem cells (hiPSCs) feature key advantages compared with rodent primary cultures. Using calcium fluorescence imaging, we tracked

FPGA implementation of an sEMG classifier

This master’s thesis discusses the implementation of a convolutional neural network on a Field Programmable Gate Array (FPGA). It deals with implementation be describing a tool chain, starting with the designing of a model in Keras, transforming the model to Hardware Descriptive Language, and finally implementing it on an FPGA. Performance on three different scales of the same model topology are c

Implementations and evaluation of machine learning algorithms on a microcontroller unit for myoelectric prosthesis control

Implementation och utvärdering av maskininlärningsalgoritmer i en mikrokontroller för kontrollsystem till myoelektrisk protes Till folk som har övre lemamputering så finns det många olika proteser. Något som håller på att utvecklas nu är proteser som kontrolleras av muskelkontraktioner, även kallad myoelektrisk protes. Myoelektrisk protes fungerar genom att ha sensorer som mäter den elektriska aUsing a microcontroller unit to implement different machine learning algorithms for myoelectric prosthesis control is currently feasible. Still there are hardware and timing constraints that need to be accounted for. This master thesis presents results from automatically generated Arduino code for some Neural Networks, Convolution Neural Networks and linear machine learning models that was impleme

Microbial ecosystem analysis of biochar-enriched soil in Kenya using microfluidic soil models

Healthy soil is rich in diverse microbial life, and a healthy microbial ecosystem is crucial for any well-functioning agriculture. Soil microbes are essential for organic decomposition and nutrient recycling in the soil, which make nutrients available for agricultural crops. Biochar-enrichment of soil has previously been found to increase crop yields in Kenya, and could potentially be a self-relia

Getting at the Experience of Confinement in Detention

A distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave. They might escape, and there are ways to be transferred, enjoy an excursion, and get permission for home visits, but typically the young people in this case are supposed to remain within their given institution. I have been eager to not only depict this feature of fielA distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave.

Detailed anatomy at 7T

Selected high resolution axial images obtained from a 7T MRI scanner have been labeled to provide detailed information about the subtle structures found in the cerebellum and brainstem.

Cardiovascular Morbidity and Mortality Related to Non-Alcoholic Fatty Liver Disease : a Systematic Review and Meta-Analysis

BACKGROUND AND AIMS: Whether non-alcoholic fatty liver disease (NAFLD) is a cardiovascular (CV) risk factor is debated. We performed a systematic review and meta-analysis to assess the CV morbidity and mortality related to NAFLD in the general population, and to determine whether CV risk is comparable between lean and non-lean NAFLD phenotypes.METHODS AND RESULTS: We searched multiple databases, i

Sulfidation of Supported Ni, Mo and NiMo Catalysts Studied by In Situ XAFS

Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied in situ. Herein we present a comparative XAFS study where the in situ sulfidation of Mo/δ-Al2O3 and Ni/δ-Al2O3 is compared to that of δ-Al2O3 supported NiMo catalysts with different NiMo ratios. The study also covers the com
