The plasmid-encoded members of paralogous gene family 52 are dispensable to the enzootic cycle of .

Lyme disease, the leading vector-borne disease in the United States and Europe, develops after infection with bacteria. Transmission of the spirochete from the tick vector to a vertebrate host requires global changes in gene expression that are controlled, in part, by the Rrp2/RpoN/RpoS alternative sigma factor cascade. Transcriptional studies defining the RpoS regulon have suggested that RpoS activates the transcription of paralogous family 52 (PFam52) genes.

Scaling national and international improvement in virtual gene panel curation via a collaborative approach to discordance resolution.

Clinical validity assessments of gene-disease associations underpin analysis and reporting in diagnostic genomics, and yet wide variability exists in practice, particularly in use of these assessments for virtual gene panel design and maintenance. Harmonization efforts are hampered by the lack of agreed terminology, agreed gene curation standards, and platforms that can be used to identify and resolve discrepancies at scale. We undertook a systematic comparison of the content of 80 virtual gene panels used in two healthcare systems by multiple diagnostic providers in the United Kingdom and Australia.

Analysis of primary central nervous system large B-cell lymphoma in the era of high-grade B-cell lymphoma: Detection of two cases with MYC and BCL6 rearrangements in a cohort of 12 cases.

High-grade diffuse large B-cell lymphoma (HG-DLBCL) refers to DLBCL with MYC and BCL2 and/or BCL6 rearrangements (double-hit or triple-hit DLBCL) that exhibits poor prognosis. Double-expressor DLBCL (c-myc+/bcl-2+) has intermediate prognosis when compared to HG-DLBCL. Primary central nervous system lymphoma (PCNSL) has distinct pathophysiology (frequent non-germinal center-like subtype and double-expressor) and has worse prognosis than systemic DLBCL.

An examination of radon awareness, risk communication, and radon risk reduction in a Hispanic community.

Radiation risk communication is a critical component of radiation protection and the public's understanding of radiation risks and benefits. Risk communication becomes even more complicated when considering cultural and language differences. In the US, many diverse communities face risk communication challenges.

Short-Duration Rapid Chilling of Mastectomy Specimens Does Not Interfere With Breast Cancer Biomarker and Molecular Testing.

Context.—: A thorough gross examination of specimens for breast cancer requires the tissue to be very thinly sectioned, which is often difficult in large mastectomy samples. We have implemented rapid chilling of mastectomy specimens before formalin fixation.
