T-cell lymphoblastic lymphoma (T-LBL) is a heterogeneous malignancy of lymphoblasts committed to T-cell lineage. Dismal outcomes (15-30%) in case of T-LBL relapses warrants for establishing risk-based treatment in future. This is a first comprehensive, systematic, integrated genome-wide analysis including relapse cases aimed towards identifying molecular markers of prognostic relevance for T-LBL. NOTCH1 was identified as putative driver for T-LBL. Activated NOTCH/PI3K-AKT signaling axis and alterations in cell cycle regulators constitutes the core oncogenic program for T-LBL. Mutated KMT2D was identified as a prognostic marker. The cumulative incidence of relapse was 47±17% in patients with KMT2D mutations compared with 14±3% in KMT2D wildtype. Structural analysis of the mutated domains of KMT2D revealed plausible impact on the structure and functional consequences. These findings provide new insights into the pathogenesis of T-LBL including high translational potential. The ongoing trial LBL 2018 (NCT04043494) allows prospective validation and subsequent fine-tuning of the stratification criteria for T-LBL risk groups to improve survival of the pediatric patients.Literature studies have demonstrated the structural, connectional, and functional differences between cortical folding patterns in mammalian brains, such as convex and concave patterns. However, the molecular underpinning of such convex/concave differences remains largely unknown. Thanks to public access to a recently released set of marmoset whole-brain in situ hybridization data by RIKEN, Japan; this data's accessibility empowers us to improve our understanding of the organization, regulation, and function of genes and their relation to macroscale metrics of brains. In this work, magnetic resonance imaging and diffusion tensor imaging macroscale neuroimaging data in this dataset were used to delineate convex/concave patterns in marmoset and to examine their structural features. Machine learning and visualization tools were employed to investigate the possible transcriptome difference between cortical convex and concave patterns. Experimental results demonstrated that a collection of genes is differentially expressed in convex and concave patterns, and their expression profiles can robustly characterize and differentiate the two folding patterns. More importantly, neuroscientific interpretations of these differentially expressed genes, as well as axonal guidance pathway analysis and gene enrichment analysis, offer novel understanding of structural and functional differences between cortical folding patterns in different regions from a molecular perspective.Drug similarities play an important role in modern biology and medicine, as they help scientists gain deep insights into drugs' therapeutic mechanisms and conduct wet labs that may significantly improve the efficiency of drug research and development. Nowadays, a number of drug-related databases have been constructed, with which many methods have been developed for computing similarities between drugs for studying associations between drugs, human diseases, proteins (drug targets) and more. In this review, firstly, we briefly introduce the publicly available drug-related databases. Secondly, based on different drug features, interaction relationships and multimodal data, we summarize similarity calculation methods in details. Then, we discuss the applications of drug similarities in various biological and medical areas. Finally, we evaluate drug similarity calculation methods with common evaluation metrics to illustrate the important roles of drug similarity measures on different applications.

ESBL- and carbapenemase-producing Pseudomonas aeruginosa are prevalent in, for example, the Middle East, Eastern Europe and Latin America, though rarer elsewhere. Because P. aeruginosa readily mutate to become carbapenem resistant via loss of OprD, isolates producing ESBLs are often as broadly resistant as those producing carbapenemases. We hypothesized that (i) relebactam might overcome class A carbapenemases directly in P. aeruginosa; and (ii) relebactam's inhibition of AmpC, which gives a generalized potentiation of imipenem against the species, might restore imipenem susceptibility in OprD-deficient ESBL producers.

MICs were determined using CLSI agar dilution for P. aeruginosa isolates producing ESBLs, principally VEB types, and for those producing GES-5, KPC and other carbapenemases.

Relebactam potentiated imipenem by around 4-8-fold for most P. learn more aeruginosa isolates producing VEB and other ESBLs; however, MICs were typically only reduced to 4-16 mg/L, thus mostly remaining above EUCAST's susceptible range and only partly overlapping CLSI's intermediate range. Strong (approx. 64-fold) potentiation was seen for isolates producing KPC carbapenemases, but only 2-fold synergy for those with GES-5. Predictably, potentiation was not seen for isolates with class B or D carbapenemase activity.

Relebactam did potentiate imipenem against ESBL-producing P. aeruginosa, which are mostly imipenem resistant via OprD loss, but this potentiation was generally insufficient to reduce imipenem MICs to the clinical range. Imipenem resistance owing to KPC carbapenemases was reversed by relebactam in P. aeruginosa, just as for Enterobacterales.

Dr. Wood moved east to New York in 1913; Dr. Guedel, west to California in 1928. By 1962, each pioneer had been honored with a namesake anesthesia museum. Fast-forwarding 55 yr, two young anesthesia historians, California's Jane Moon, M.D., and Pennsylvania's Melissa Coleman, M.D., met at the 2017 International Symposium of the History of Anesthesia in Boston. Today, these women are chairs of the Wood Library-Museum's Archives and Museum Committees, respectively. As the newest authors of "Anesthesiology Reflections," Drs. Coleman and Moon leave their coastal states semiannually for board meetings at the Wood Library-Museum of Anesthesiology, returning as legacies of Drs. Wood and Guedel…back to the American Heartland.
