El trabajo de investigación científico-tecnológico teórico y aplicado requiere creatividad, disciplina y sistematicidad. Es necesario que la disposición creativa de lxs científicxs esté guiada, también, por un
riguroso proceso de análisis, organización del material recopilado, de interrogación y autocrítica de las ideas disponibles, de posibilidad de comunicación efectiva de los resultados, en las condiciones reales de la disciplina de pertenencia. Desde la perspectiva cualitativa la práctica científica siempre está abierta a lo multiverso y a la complejidad de los fenómenos que se deciden estudiar.

Abordando los tres ejes, el onto-epistemológico, el técnico-procesual y el ético-deontológico presentes en las investigaciones del campo de lo humano, el curso se concentrará en sostener los postulados básicos de toda investigación cualitativa: la sustitución de la dualidad epistemológica sujeto-objeto por formas de conocimientos “de” y “con” el otro, el paso de una observación pasiva y alejada del fenómeno estudiado hacia formas activas e interactuantes, y la trasformación de una aparente neutralidad valorativa
paralizante en un compromiso ético-político científico.

Estos cursos se enmarcan dentro del ACUERDO PARITARIO entre la UNMdP y la Agremiación Docente Universitaria Marplatense.

Online Seminar: “SynDLP, the fusogenic Dynamin-like protein of Synechocystis sp. PCC 6803”

July 28th, 2022, 9AM CEST

Lucas Gewehr (University of Mainz, Germany)

Dynamin-like proteins (DLPs) are large GTPases that utilize the energy of GTP hydrolysis to remodel membranes via membrane fission or fusion. Unlike many eukaryotic DLPs, only few bacterial DLPs (BDLPs) have been identified and characterized thus far. The first BDLP was identified in the cyanobacterium Nostoc punctiforme 16 years ago. However, the first, and thus far only, putative in vivo function of a BDLP has been discovered very recently in Bacillus subtilis. While cyanobacteria contain an extended and highly dynamic thylakoid membrane (TM) system, biogenesis and dynamics of this internal membrane structure is still poorly understood. An involvement of BDLPs in remodeling of cyanobacterial membranes is well conceivable.

In this talk I will present SynDLP, a novel DLP encoded in the cyanobacterium Synechocystis sp. PCC 6803. Hitherto, we focused on in vitro analysis with the isolated protein. SynDLP interacts with negatively charged TM lipids and forms oligomers in solution in absence of lipids and/or nucleotides, features not observed with other BDLPs. As SynDLP is capable of liposome fusion in vitro, we categorized it as a fusion DLP. To better understand the structure and functions of SynDLP, we also determined a cryo-TEM structure of SynDLP oligomers up to a resolution of 3.6 Å. Besides a typical dynamin-like modular domain arrangement, the structure revealed new DLP features, such as an intramolecular disulfide bond in the bundle signaling element (BSE) and an expanded interface between the BSE and the GTPase domain (GD). Typically, DLPs show stimulated GTPase activity in the presence of an appropriate membrane surface. Yet, SynDLP already shows a relatively high basal GTPase activity without lipids. Removal of the BSE stabilizing disulfide bond or BSE-GD contacts affects the SynDLP GTPase activity and stability of SynDLP oligomers, indicating a hitherto unique concept of DLP trans-activation.

ASPB – Plant Science Research Articles of the Week – July 28, 2022

Plant Physiology Article of the Week: Single-parent Expression Complementation Contributes to Phenotypic Heterosis in Maize Hybrids The spotlight is on Jutta A Baldauf, Meiling Liu, Lucia Vedder, Peng Yu, Hans-Peter Piepho, Heiko Schoof, Dan Nettleton, and Frank Hochholdinger. Their research shows that the number of single parent expression complementation patterns is significantly associated with mid-parent heterosis for all surveyed phenotypic traits in maize.

The Plant Cell Article of the Week: Diversification of Heat Shock Transcription Factors Expanded Thermal Stress Responses During Early Plant Evolution The spotlight is on Ting-Ying Wu, Kar Ling Hoh, Kulaporn Boonyaves, Shalini Krishnamoorthi, and Daisuke Urano from Temasek Life Sciences Laboratory in Singapore. They demonstrate that functional distinctions between Heat Shock Factors A and B in Marchantia are linked to processes that were newly connected to heat-responsive gene regulatory networks in early land plants.

Plant Direct Article of the Week: Keeping Time in the Dark: Potato Diel and Circadian Rhythmic Gene Expression Reveals Tissue-specific Circadian Clocks The spotlight is on Michigan State University researchers Genevieve M. Hoopes, Daniel Zarka, Ann Feke, Kaitlyn Acheson, John P. Hamilton, David Douches, C. Robin Buell, and Eva M. Farré. Their research has provided the first evidence of a functional circadian clock in below-ground storage organs, holding important implications for other storage root and tuberous crops.

Science Webinar: “Understanding Epstein-Barr virus–associateddisease via spatial phenotyping:From primary infection to malignancy

Overview

Spatial phenotyping allows researchers to view, characterize, and quantify cells by lineage and variant with single-cell resolution in the context of an intact tissue sample. In areas such as oncology, immunology, and neurodegenerative and infectious diseases, it has opened new insights into the interplay between different cellular actors in promoting or suppressing disease. The Epstein-Barr virus (EBV), a group 1 carcinogen, is a causative factor for nine different cancers that cause roughly 165,000 deaths globally each year. EBV is asymptomatically carried among almost all adults, with the virus persisting primarily in rare memory B cells. However, in some infected individuals, EBV is associated with the development of cancer. The immune microenvironment in which infected cells reside may influence or trigger cancer development, but it is still unknown how this occurs.

This webinar will address how spatial phenotyping is uniquely suited to outline one of the putative causative relationships between EBV infections, immunosuppression, and cancer.

During this webinar, viewers will:

• Learn how a meticulously designed and highly specific antibody panel provides the sensitivity and specificity required to characterize Epstein-Barr virus (EBV)
• Be presented with a framework that associates specific EBV expression profiles with a unique tissue architecture and immune infiltrate
• Discover how end-to-end analysis pipelines are used to examine high-dimensional spatial data
• Uncover how cellular neighborhood analysis of nasopharyngeal carcinoma provides unbiased analysis of tissue microenvironments.
