Preparing for the Unprecedented: The Association of Biomolecular Resource Facilities (ABRF) Community Coronavirus Disease 2019 (COVID-19) Pandemic Response Part 1: Efforts to Sustainably Ramp Down Core Facility Activities.

The coronavirus disease 2019 (COVID-19) pandemic has curtailed all but the most critical laboratory research in many institutions around the world. These unplanned and unprecedented operational changes have put considerable stress on every aspect of the research enterprise, from funding agencies to research institutes, individual and core laboratories, researchers, and research administrators, with drastic changes in demands and deliverables. The Association of Biomolecular Resource Facilities Core Administrators Network Coordinating Committee initiated a forum-wide discussion followed by a global survey to gain information on how institutions and, specifically, shared resource core facilities were responding to the COVID-19 pandemic. The survey aimed to identify shared resource core facility challenges and opportunities related to operational ramp downs, shutdowns, or research "pauses" during the COVID-19 pandemic, as well as new practices and resources needed to ensure business continuity. Although a number of positive outcomes from remote work hold promise for improved core operations, the survey results revealed a surprising level of unfamiliarity with business continuity planning for cores and limited coordination within institutions. Recommendations for business continuity planning include key stakeholders working together to assess risk, prioritize work, and promote transparency across campus.

The human body at cellular resolution: the NIH Human Biomolecular Atlas Program.

Transformative technologies are enabling the construction of three-dimensional maps of tissues with unprecedented spatial and molecular resolution. Over the next seven years, the NIH Common Fund Human Biomolecular Atlas Program (HuBMAP) intends to develop a widely accessible framework for comprehensively mapping the human body at single-cell resolution by supporting technology development, data acquisition, and detailed spatial mapping. HuBMAP will integrate its efforts with other funding agencies, programs, consortia, and the biomedical research community at large towards the shared vision of a comprehensive, accessible three-dimensional molecular and cellular atlas of the human body, in health and under various disease conditions.

Guía de Procedimientos Operacionales y Recomendaciones en la Implementación de Secuenciación de Nueva Generación para Diagnóstico Clínico / Standard Operational Procedures and Rec ommendations on Next Generation Sequenc ing for Clinic al Diagnostics

La tecnología diagnóstica conocida como NGS por sus siglas en inglés, o Secuenciación de nueva generación, es relativamente nueva, y se está implementando en algunos hospitales de Panamá. Esta tecnología ha demostrado ser una herramienta muy eficiente para la detección de alteraciones genómicas o exómicas, tanto para la clínica como para la investigación. Dada la complejidad de esta prueba, requiere una infraestructura y un número importante de recursos humanos capacitados para poder implementar esta prueba. El propósito de este documento es establecer un marco de referencia para los procedimientos administrativos en cuanto a la realización de las pruebas de secuenciación por metodología NGS. Además, que el mismo sirva de guía para el establecimiento adecuado de programas internos de control y evaluación de calidad de esta tecnología en nuestro país y la región

The technology known as Next­Generation sequencing is relatively new, and it is been implemented in some Panamanian hospitals. It has demonstrated to be a very efficient tool to identify genomic and exomic variants in a clinical setting, as well for research purposes. Because of its complexity, it requires an important infrastructure and a significant number of trained health­care professionals to carry out this test. The purpose of this document is to establish a frame for the administrative and tec hnical aspects for NGS in a clinical setting. Moreover, it will serve as a guide to establish quality control procedures that the technology requires in our country and the region.

European contribution to the study of ROS: A summary of the findings and prospects for the future from the COST action BM1203 (EU-ROS).

The European Cooperation in Science and Technology (COST) provides an ideal framework to establish multi-disciplinary research networks. COST Action BM1203 (EU-ROS) represents a consortium of researchers from different disciplines who are dedicated to providing new insights and tools for better understanding redox biology and medicine and, in the long run, to finding new therapeutic strategies to target dysregulated redox processes in various diseases. This report highlights the major achievements of EU-ROS as well as research updates and new perspectives arising from its members. The EU-ROS consortium comprised more than 140 active members who worked together for four years on the topics briefly described below. The formation of reactive oxygen and nitrogen species (RONS) is an established hallmark of our aerobic environment and metabolism but RONS also act as messengers via redox regulation of essential cellular processes. The fact that many diseases have been found to be associated with oxidative stress established the theory of oxidative stress as a trigger of diseases that can be corrected by antioxidant therapy. However, while experimental studies support this thesis, clinical studies still generate controversial results, due to complex pathophysiology of oxidative stress in humans. For future improvement of antioxidant therapy and better understanding of redox-associated disease progression detailed knowledge on the sources and targets of RONS formation and discrimination of their detrimental or beneficial roles is required. In order to advance this important area of biology and medicine, highly synergistic approaches combining a variety of diverse and contrasting disciplines are needed.

Caracterización de mecanismos de resistencia por biología molecular: Staphylococcus aureus resistente a meticilina, b-lactamasas de espectro extendido y carbapenemasas / Molecular characterization of resistance mechanisms: methicillin resistance Staphylococcus aureus, extended spectrum b-lactamases and carbapenemases

La resistencia a múltiples antibióticos en bacterias patógenas aumenta la morbimortalidad de los pacientes infectados y es una grave amenaza para la salud pública por su capacidad de diseminación. Por ambos motivos, la detección rápida de las bacterias multirresistentes es crucial. Los métodos de diagnóstico microbiológico convencionales requieren al menos 48-72 h, por lo que se necesitan otros procedimientos que permitan agilizar la obtención de resultados. En los últimos años se ha extendido el uso de técnicas basadas en medios de cultivo selectivos y diferenciales, así como el de otras técnicas fenotípicas. Sin embargo, la capacidad de detectar los genes de resistencia y la rapidez en la obtención de resultados han convertido los métodos moleculares en técnicas de referencia. Esta revisión aborda los diferentes métodos moleculares de detección de los genes que codifican algunos de los mecanismos de resistencia a antibióticos con mayor impacto a nivel clínico y epidemiológico en el momento actual: a) la resistencia enzimática a antibióticos b-lactámicos de amplio espectro en enterobacterias, principalmente b-lactamasas de espectro extendido y carbapenemasas, y b) la resistencia a meticilina en Staphylococcus aureus

Multi-drug resistance in bacterial pathogens increases morbidity and mortality in infected patients and it is a threat to public health concern by their high capacity to spread. For both reasons, the rapid detection of multi-drug resistant bacteria is critical. Standard microbiological procedures require 48-72 h to provide the antimicrobial susceptibility results, thus there is emerging interest in the development of rapid detection techniques. In recent years, the use of selective and differential culture-based methods has widely spread. However, the capacity for detecting antibiotic resistance genes and their low turnaround times has made molecular methods a reference for diagnosis of multidrug resistance. This review focusses on the molecular methods for detecting some mechanisms of antibiotic resistance with a high clinical and epidemiological impact: a) Enzymatic resistance to broad spectrum b-lactam antibiotics in Enterobacteriaceae, mainly extended spectrum b-lactamases (ESBL) and carbapenemases; and b) methicillin resistance in Staphylococcus aureus

Monod as the founder of a new discipline: local and international contexts.

Monod gained stature as an experimentalist and theorist as well as a discipline builder. The essay reviews the intimate connection of the intellectual and institutional projects in his career. A brief comparison with the development of the new science of molecular biology across the English Channel highlights the commonalities and specificities of the disciplinary projects in France and Britain and the role that individuals like Monod played in their formation. The article argues that there was not a single path that led to the rise of molecular biology. Rather individual initiatives and historical contingencies very much shaped local outcomes.
