TL;DR: In this article, the efficacy of PCR detection of SARS-CoV-2 between paired nasopharyngeal and saliva samples in nine COVID-19 patients was evaluated.
Journal ArticleDOI
Mass Screening of Asymptomatic Persons for Severe Acute Respiratory Syndrome Coronavirus 2 Using Saliva.
Isao Yokota,Peter Y Shane,Kazufumi Okada,Yoko Unoki,Yichi Yang,Tasuku Inao,Kentaro Sakamaki,Sumio Iwasaki,Kasumi Hayasaka,Junichi Sugita,Mutsumi Nishida,Shinichi Fujisawa,Takanori Teshima +12 more
TL;DR: Self-collected saliva is a valuable specimen to detect SARS-CoV-2 in mass screening of asymptomatic persons because of its high sensitivity and specificity.
Journal ArticleDOI
Upregulation of microRNA-126-5p is associated with drug resistance to cytarabine and poor prognosis in AML patients.
TL;DR: Higher expression levels above the median value of miR-126-5p/3p were correlated with a poorer overall survival and elevated the phosphorylation of Akt, which resulted in a poorer prognosis in patients with AML.

Comparison of SARS-CoV-2 detection in nasopharyngeal swab and saliva
Sumio Iwasaki,Shinichi Fujisawa,Sho Nakakubo,Keisuke Kamada,Yu Yamashita,Tatsuya Fukumoto,Kaori Sato,Satoshi Oguri,Keisuke Taki,Hajime Senjo,Kasumi Hayasaka,Satoshi Konno,Mutsumi Nishida,Takanori Teshima +13 more
TL;DR: Results suggest that saliva is a reliable noninvasive alternative to nasopharyngeal swabs and facilitate widespread PCR testing in the face of shortages ofSwabs and protective equipment without posing a risk to healthcare workers.
Journal ArticleDOI
Efficacy of a novel SARS-CoV-2 detection kit without RNA extraction and purification.
Tatsuya Fukumoto,Sumio Iwasaki,Shinichi Fujisawa,Kasumi Hayasaka,Kaori Sato,Satoshi Oguri,Keisuke Taki,Sho Nakakubo,Keisuke Kamada,Yu Yamashita,Satoshi Konno,Mutsumi Nishida,Junichi Sugita,Takanori Teshima +13 more
TL;DR: A novel “2019 Novel Coronavirus Detection Kit (nCoV-DK)” halves detection time by eliminating the steps of RNA extraction and purification, while reducing time required for detection, labor, and risk of human error.
