We evaluate the proposed methods on four benchmark datasets. The experimental results show that our methods significantly outperform all previous works on every dataset in terms of both speed and accuracy.Numerous anti-cancer drugs perturb thymidylate biosynthesis and lead to genomic uracil incorporation contributing to their antiproliferative effect. Still, it is not yet characterized if uracil incorporations have any positional preference. Here, we aimed to uncover genome-wide alterations in uracil pattern upon drug treatments in human cancer cell line models derived from HCT116. We developed a straightforward U-DNA sequencing method (U-DNA-Seq) that was combined with in situ super-resolution imaging. Using a novel robust analysis pipeline, we found broad regions with elevated probability of uracil occurrence both in treated and non-treated cells. Correlation with chromatin markers and other genomic features shows that non-treated cells possess uracil in the late replicating constitutive heterochromatic regions, while drug treatment induced a shift of incorporated uracil towards segments that are normally more active/functional. Data were corroborated by colocalization studies via dSTORM microscopy. This approach can be applied to study the dynamic spatio-temporal nature of genomic uracil.Coronavirus disease 2019 (COVID-19) is a new, rapidly spreading pandemic that can lead to a life-threatening disease. Accurate and transparent COVID-19 case reports provide systematic clinical observations supporting researchers designing clinical trials and clinicians delivering health care. The checklist described here is designed to systematically and accurately capture data from case reports and case series for documentation on COVID-19. It is aligned with the CARE guidelines, available from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network.The Senate of The University of Queensland, on the recommendation of the Executive Board of the International Committee on Systematics of Prokaryotes, is pleased to present the van Niel International Prize for Studies in Bacterial Systematics for the triennium 2017-2020 to Dr Tanja Woyke in recognition of her contributions made to the field of bacterial systematics. The award, established in 1986 by Professor V. B. D. Skerman of The University of Queensland, honours the contribution of scholarship in the field of microbiology by Professor Cornelis Bernardus van Niel.Cryptococcus neoformans is a lethal fungus disguised in a polysaccharide coat. It can remain dormant in the host for decades prior to reactivation, causing systemic cryptococcosis in humans and other mammals. Cryptococcus deploys a multitude of traits to adapt to and survive within the host, including immunosuppression, an ability to replicate intra- and extra-cellularly in phagocytes, changes in morphology and ploidy, a predilection to infect the CNS, and the capacity to utilize neurotransmitters and unique carbon sources available in the brain. These pathogenic strategies displayed by this fungus might have evolved through its interactions with microbial predators in the environment.Two anaerobic bacteria, designated strains SYSU GA16112T and SYSU GA16107, were isolated from a hot spring in Tengchong County, Yunnan Province, south-west PR China. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains SYSU GA16112T and SYSU GA16107 belong to the family Dysgonamonadaceae. Cells of strains SYSU GA16112T and SYSU GA16107 were Gram-stain-negative, rod-shaped and non-motile. The major fatty acids (>10 %) of strains SYSU GA16112T and SYSU GA16107 were identified as anteiso-C15  0 and anteiso-C17  0 3OH. The polar lipid profile of strain SYSU GA16112T was found to consist of phosphatidylethanolamine, two unidentified aminophospholipids, two unidentified phosphoglycolipids, two unidentified aminolipids and one unidentified polar lipid, while that of strain SYSU GA16107 consisted of phosphatidylethanolamine, two unidentified polar lipids, three unidentified aminophospholipids, two unidentified phosphoglycolipids and one unidentified aminolipid. The genomic DNA G+C contents of strains SYSU GA16112T and SYSU GA16107 were determined to be 41.90 and 41.89 %, respectively, and the average nucleotide identity value between them was 99.99 %. Based on their morphological and physiological properties, and results of phylogenetic analyses, strains SYSU GA16112T and SYSU GA16107 are considered to represent a novel species of a novel genus, for which the name Seramator thermalis gen. nov., sp. nov. (type strain SYSU GA16112T=CGMCC 1.5281T=KCTC 15753T) is proposed.HistoryA 63-year-old woman with a history of left mastectomy for breast cancer and partial gastrectomy with Roux-en-Y reconstruction for nonhealing peptic ulcer presented to the emergency department and reported a 1-month history of abdominal distention, fevers, chills, and flu-like symptoms. She was initially suspected of having flu, and she completed a course of oseltamivir; however, she had continued to experience fatigue, fever, chills, abdominal bloating, and loss of appetite. She reported no contact with a sick person or recent travel. At admission, laboratory studies revealed leukocytosis, with a white blood cell count of 15.1 × 103/μL (15.1 × 109/L) (normal range, 4.0-10.0 × 103/μL [4.0-10.0 × 109/L]), an elevated sedimentation rate of 100 mm per hour (normal range, 0-30 mm per hour), and a C-reactive protein level of 203.8 mg/L (1940.9 nmol/L) (normal range, ≤10 mg/L [≤95.2 nmol/L]). Liver enzyme levels were elevated, with an alanine aminotransferase level of 48 U/L (0.80 µkat/L) (normal range, 0-29 U/L [0-0.48 µkat/L]), an aspartate aminotransferase level of 98 U/L (1.6 µkat/L) (normal range, 10-37 U/L [0.16-0.62 µkat/L]), an alkaline phosphatase level of 682 U/L (11.4 μkat/L) (normal range, 65-195 U/L [1.1-3.3 μkat/L]), and a total bilirubin level of 1.5 mg/dL (25.7 µmol/L) (normal range, 0.3-1.0 mg/dL [5.1-17.1 μmol/L]). Abdominopelvic CT was performed.History A 70-year-old man had a posterior left thigh lesion confirmed to be biopsy-proven melanoma. The patient underwent wide excision and sentinel node biopsy, which showed absence of residual melanoma. Two years later, the patient noticed a subcentimeter subcutaneous lump in his thigh. Tasocitinib Repeat excisional biopsy showed involvement of the surrounding soft tissue, consistent with a satellite lesion. Follow-up combined PET/CT revealed satellite nodules around the primary lesion, enabling confirmation of subcutaneous metastatic disease. The patient was subsequently started on nivolumab, an anti-programmed cell death 1 (PD-1) immune checkpoint inhibitor that blocks PD-1 and is approved as a first-line treatment in patients with advanced metastatic melanoma. On the baseline scan prior to starting nivolumab, there were no CT findings that suggested metastatic disease, nor were there enlarged mediastinal or hilar lymph nodes. Five months after initiation of nivolumab treatment, the first follow-up chest CT scan was performed and showed new findings in the mediastinum (Fig 1) and bilateral lungs (Figs 2, 3).
