Estudio de efectos térmicos en reactores monolíticos para la combustión catalítica de COVs
… catalítica de compuestos orgánicos volátiles (COVs) en la descontaminación de corrientes de aire industrial previo a su emisión al ambiente. Esto se realiza utilizando reactores monolíticos integrados energéticamente con un intercambiador de calor y un horno. El intercambiador de calor …

Animal models for investigating coronavirus heterotypic immunity
Endemic coronaviruses (CoVs) such as OC43 circulate seasonally and, while usually mild, represent the 6th leading cause of viral pneumonia. Additionally, multiple zoonotic spillovers of CoVs have occurred in the last 25 years to cause severe pneumonia, most recently the coronavirus disease 2019 …

Genetic structure of scent profiles in antirrhinum : implications for the evolution and Interaction with pests and pollinator
… Combinaciones de Compuestos Orgánicos Volátiles (COVs) intervienen en las interacciones entre plantas y otros reinos. Los aromas florales juegan un papel importante en la polinización y la supervivencia de las especies. Los COVs emitidos por las plantas se pueden agrupar en dos clases: compuestos …

PATTERNS OF NATURAL SELECTION ASSOCIATED WITH TROPISM SHIFTS IN ANIMAL CORONAVIRUS GENOMES
… shift. RNA viruses, such as Coronaviruses (CoVs), are susceptible to tropism shifts. A tropism shift occurs when a virus alters the tissue or cell type it infects, which can have important implications for disease pathogenesis, virulence, transmission, and treatment control. Tropism shifts …

Measurement and modelling of combustion in a spark ignition engine
… onset of knock has no discernible effect on the COVs of the measured parameters. The part throttle results show higher COVs than at Wide Open Throttle (WOT) due to slower burn, supporting the theory that faster initial flame speeds reduce cyclic variations. The combustion model was used to …

Identification of Transmembrane and Extracellular Host Proteases that Promote Human CoV Entry and Syncytium Formation
Coronaviruses (CoVs) comprise a family of enveloped viruses that cause respiratory disease in humans, including CoV disease 2019 (COVID-19), caused by severe-acute respiratory syndrome CoV-2 (SARS-CoV-2). For CoV infection to occur, the CoV spike (S) protein must mediate fusion between the viral …

Subversion of innate antiviral immunity by SARS-CoV-2: An example from the study of nonstructural protein 16.
… process. Based on observations with other CoVs, we hypothesized that NSP16 2’-O MTase function protects SARS-CoV-2 from cap-sensing host restriction. Therefore, we engineered SARS-CoV-2 with a mutation that disrupts a conserved residue in the active site of NSP16. We subsequently show that …

Structural and functional studies of the papain-like protease 2 from mouse hepatitis virus
… served as a model system for the study of CoVs, and it has undeniable advantage of ease in culturing in comparison to human coronaviruses.</p> <p>It is reported here the expression and purification of a region of MHV nsp3 that contains the catalytic core of the PLP2 domain and its …

Structural and Functional Studies of the SARS-CoV-2 NiRAN Domain
… Global understanding of the threats posed by CoVs circulating among animals in the wild has increased, powering the urgency for new research into CoV biology. We study CoV replicase enzymes to shed light on the mechanisms underpinning viral replication and gene expression in the hope to …

Structures, Functions, and Druggability of the SARS-CoV-2 Replication–Transcription Complex
… agent, SARS-CoV-2, and more broadly related CoVs. An essential aspect of viral propagation is the replication process in which viral enzymes orchestrate the production of nascent viral RNA genomes. CoV RNA synthesis is mediated by the RNA-dependent RNA polymerase (RdRp) which requires a …

Meccanismi di difesa e interazioni multitrofiche tra Solanum spp. e Tuta absoluta
La conoscenza delle interazioni pianta-insetto e della resistenza delle piante rappresenta un'opzione chiave di controllo per ottimizzare la gestione sostenibile e integrata dei parassiti e quindi per ridurre l’uso degli insetticidi. Le piante sono in grado di rispondere agli stress abiotici e …
