Sommario/riassunto |

COVID-19 is the most prominent and rapidly evolving public health concern in the world currently. The gastrointestinal manifestations of COVID-19 are increasingly being recognized. SARS-CoV-2 infection has been associated with the occurrence of nausea, vomiting, and diarrhea. SARS-CoV-2 has also been causing pancreatic and hepatic injury. Emerging data have shown that COVID-19 patients continue to shed the virus into their stools, even when patients test negative for COVID-19 in pulmonary secretions. However, the epidemiology, pathogenesis, and treatment of SARS-CoV-2-related gastrointestinal manifestations are poorly understood. The pandemic has also had a significant impact on gastroenterologists, endoscopists, and other ancillary staff. Moreover, in the past, systematic respiratory virus syndrome (SARS) was shown to be transmitted by endoscopes, which is a big concern with COVID-19, as it shares many pathological features with SARS. The deferral of elective endoscopic procedures has negatively affected gastroenterologists. This Special Issue focuses on the current situation of this pandemic. It aims to provide insight into the gastrointestinal manifestations of COVID-19 and its effects on endoscopic procedures. I believe that this issue will be beneficial not only for gastroenterologists but also other healthcare workers around the world to recognize the often-ignored clinical gastrointestinal manifestations of COVID-19. |

Sommario/riassunto |
|
"Quantum Oscillators is a valuable source of information and an excellent supplementary text in courses on spectroscopy of hydrogen-bonded systems, one of the unsolved problems of science. This reference provides a reasonable and accessible entrance to the difficult subject of nonequilibrium quantum mechanics and is a timely update of classical works while, at the same time, providing a comprehensive treatment of hydrogen bonding. Also included is an appendix that summarizes mathematical concepts needed to understand the basis of the theory"-- |
"The book is divided into four parts. The first part is devoted to the concepts of quantum mechanics the knowledge of which is necessary |

for a good understanding of the dynamics of quantum oscillator which may be damped, and deals with time independent quantum mechanics and time dependent quantum mechanics"-- |
