Impact of the early months of the COVID-19 pandemic on the sleep patterns of a Brazilian population sample
Chronobiol Int. 2023 Sep 12:1-13. doi: 10.1080/07420528.2023.2255667. Online ahead of print.ABSTRACTHumanitarian and health crisis have drastic effects on the physical and mental well-being of people. The COVID-19 pandemic forced many countries to impose containment measures on its population to halt the spread of the new coronavirus (SARS-CoV-2). This aim of this study was to explore self-reported sleep quality and insomnia symptoms in a sample of the Brazilian population before and during the COVID-19 quarantine period. Our data was collected through online questionnaires, including the Pittsburgh Sleep Quality Index, th...

CROI 2023: Summary of Basic Science Research in HIV
Top Antivir Med. 2023 Jun 30;31(4):523-528.ABSTRACTThe 2023 Conference on Retroviruses and Opportunistic Infections (CROI) represented the first fully in-person conference since the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic began. CROI continues as the premier conference in which delegates can appraise themselves of almost every facet of HIV/AIDS research as well as emerging and re-emerging pathogens such as SARS-CoV-2 and mpox. The return to an in-person format is particularly important for early-stage investigators, who were faced with challenges of advancing their independent research careers...

Obtaining a high titer of polyclonal antibodies from rats to the SARS-CoV-2 nucleocapsid protein and its N- and C-terminal domains for diagnostic test development
J Immunol Methods. 2023 Sep 11:113558. doi: 10.1016/j.jim.2023.113558. Online ahead of print.ABSTRACTSevere Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is an enveloped, plus-stranded RNA virus responsible for the Coronavirus Disease 2019 (COVID-19). Patients infected with COVID-19 may be asymptomatic or have symptoms ranging from mild manifestations to severe cases of the disease that could lead to death. The SARS-CoV-2 genome encodes 4 structural proteins, including the Spike protein (S), the Nucleocapsid protein (N), membrane protein (M) and, the envelope (E). The N protein forms a major component of the ribonu...

Inflammasome activation by SARS-CoV-2 and its participation in COVID-19 exacerbation
Curr Opin Immunol. 2023 Sep 11;84:102387. doi: 10.1016/j.coi.2023.102387. Online ahead of print.ABSTRACTCOVID-19 is an infectious and inflammatory disease caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus-2) that might progress to severe illness in humans, characterized by excessive pulmonary and systemic inflammation. Exacerbated production of inflammatory cytokines and cell death contributes to disease aggravation and the inflammasomes take a central stage in this process. Activation of the NLRP3 has been demonstrated in macrophages and monocytes infected in vitro, in mouse models of infection, and in c...

Changing Molecular Profiles of Human Cryptosporidiosis Cases in Scotland as a Result of the Coronavirus Disease, COVID-19 Pandemic
This report assessed the impact of the pandemic on Scottish cryptosporidiosis cases, and identified changes in circulating molecular variants of Cryptosporidium species. Molecular data generated using real time PCR and GP60 nested-PCR assays on laboratory-confirmed cryptosporidiosis cases reported during 2018-22 were analysed. The Scottish Microbiology Reference Laboratories (SMiRL), Glasgow, received 774 Cryptosporidium-positive faeces during 2018-22, of which 486 samples were successfully subtyped. During this time period, C. hominis (n = 155; 21%) and C. parvum (n = 572; 77%) were the most commonly detected species. The...
