    Measurement of the Length of the Integrated Donor DNA during Bacillus subtilis Natural Chromosomal Transformation
    Authors:  Ester Serrano and Begoña Carrasco, date: 08/20/2019, view: 40, Q&A: 0
    For natural transformation to occur, bacterial cells must first develop a programmed physiological state called competence. Competence in Bacillus subtilis, which occurs only in a fraction of cells, is a transient stress response that ...
    Non-invasive Quantification of Cell Wall Porosity by Fluorescence Quenching Microscopy
    Authors:  Xiaohui Liu, Thomas Günther Pomorski and Johannes Liesche, date: 08/20/2019, view: 48, Q&A: 0
    All bacteria, fungi and plant cells are surrounded by a cell wall. This complex network of polysaccharides and glycoproteins provides mechanical support, defines cell shape, controls cell growth and influences the exchange of substances between the ...
    Assessment of Metacaspase Activity in Phytoplankton
    Authors:  Dina Spungin and Ilana Berman-Frank, date: 08/20/2019, view: 36, Q&A: 0
    Programmed cell death (PCD) is an irreversible, genetically-controlled form of cell suicide in which an endogenous biochemical pathway leads to morphological changes and ultimately, cellular demise. PCD is accompanied by de-novo protein ...
    Measurement of the Length of the Integrated Donor DNA during Bacillus subtilis Natural Chromosomal Transformation
    Authors:  Ester Serrano and Begoña Carrasco, date: 08/20/2019, view: 40, Q&A: 0
    [Abstract] For natural transformation to occur, bacterial cells must first develop a programmed physiological state called competence. Competence in Bacillus subtilis, which occurs only in a fraction of cells, is a transient stress response that allows cells to take up DNA from the environment. During natural chromosomal transformation, the ...
    Non-invasive Quantification of Cell Wall Porosity by Fluorescence Quenching Microscopy
    Authors:  Xiaohui Liu, Thomas Günther Pomorski and Johannes Liesche, date: 08/20/2019, view: 48, Q&A: 0
    [Abstract] All bacteria, fungi and plant cells are surrounded by a cell wall. This complex network of polysaccharides and glycoproteins provides mechanical support, defines cell shape, controls cell growth and influences the exchange of substances between the cell and its surroundings. Despite its name, the cell wall is a flexible, dynamic structure. ...
    Assessment of Metacaspase Activity in Phytoplankton
    Authors:  Dina Spungin and Ilana Berman-Frank, date: 08/20/2019, view: 36, Q&A: 0
    [Abstract] Programmed cell death (PCD) is an irreversible, genetically-controlled form of cell suicide in which an endogenous biochemical pathway leads to morphological changes and ultimately, cellular demise. PCD is accompanied by de-novo protein synthesis of a family of proteases-"caspases" that are often used as a diagnostic marker of PCD. ...
    Optimized Protocol for the Incorporation of FDAA (HADA Labeling) for in situ Labeling of Peptidoglycan
    Authors:  Katharina Peters, Manuel Pazos, Michael S. VanNieuwenhze and Waldemar Vollmer, date: 08/05/2019, view: 218, Q&A: 0
    [Abstract] The essential peptidoglycan (PG) layer surrounds the cytoplasmic membrane in nearly all bacteria. It is needed to maintain the shape of the cell and protect it from lysis due to high turgor. Growth of the PG layer is a complex process that involves the activities of PG synthases and hydrolases during elongation and cell division. PG growth sites ...
    Visualizing Hypoxia in a Murine Model of Candida albicans Infection Using in vivo Biofluorencence
    Authors:  José Pedro Lopes and Constantin F. Urban, date: 08/05/2019, view: 294, Q&A: 0
    [Abstract] Candida albicans is a leading human fungal pathogen that uses several metabolic adaptations to escape immune cells and causes systemic disease. Here, we describe a protocol for measuring one of these adaptations, the ability to thrive in hypoxic niches. Hypoxia was generated after successful subdermal infection with C. albicans ...
    Solid Phase PCR on 3D Microstructure ArrayChip for Pathogen Detection Application
    Authors:  Krishna Kant and Tien Anh Ngo, date: 08/05/2019, view: 213, Q&A: 0
    [Abstract] Advanced free angle photolithography (FAPL) is presented for making 3D supercritical angle fluorescence (SAF) microstructures and transfer them on to polymeric chips using injection molding technique for low-cost microfluidic devices embedded with optical sensing structures. A solid phase polymerase chain reaction (SP-PCR) is used as model ...
    Image-based Quantification of Direct Cell-to-cell Transmission of Bovine Viral Diarrhea Virus
    Authors:  Fernando Merwaiss and Diego E. Alvarez, date: 08/05/2019, view: 191, Q&A: 0
    [Abstract] Different viruses rely on direct cell-to-cell transmission to propagate infection within the infected host. Measuring this mode of transmission in cultured cells is often complicated by the contribution of cell free viruses to spread, and the difficulty to distinguish between primary infected cells that produce the virus and neighboring cells that ...
    QUEEN-based Spatiotemporal ATP Imaging in Budding and Fission Yeast
    Author:  Masak Takaine, date: 08/05/2019, view: 251, Q&A: 0
    [Abstract] Yeasts have provided an exceptional model for studying metabolism and bioenergetics in eukaryotic cells. Among numerous metabolites, adenosine triphosphate (ATP) is a major metabolite that is essential for all living organisms. Therefore, a clearer understanding of ATP dynamics in living yeast cells is important for deciphering cellular energy ...
    Endocytosis Detection in Magnaporthe oryzae
    Authors:  Muxing Liu and Zhengguang Zhang, date: 08/05/2019, view: 191, Q&A: 0
    [Abstract] Endocytosis is an intracellular trafficking pathway that occurs in nutrient uptake, signal transduction and reconstruction of cell polarity and is conserved in eukaryotic cells. In fungi, endocytosis plays crucial roles in the physiology of hyphal growth and pathogenicity. vidence for endocytosis in filamentous fungi is detected by the ...
    Precision Technique for Splenectomy Limits Mouse Stress Responses for Accurate and Realistic Measurements for Investigating Inflammation and Immunity
    Authors:  Shengwen Calvin Li, Anthony D. Rangel and Mustafa H. Kabeer, date: 08/05/2019, view: 242, Q&A: 0
    [Abstract] Splenectomy in an animal model requires a standardized technique utilizing best practice to avoid variability which can result in adverse impact to the animal resulting in flawed physiologic responses simply due to technique rather than to the studied variables. In the case of the spleen, often investigators are analyzing the animal immune or ...
