Emergence of ceftriaxone-resistant Neisseria gonorrhoeae through horizontal gene transfer among Neisseria spp.

Objectives: It has been suggested that the emergence of ceftriaxone-resistant strains of Neisseria gonorrhoeae involves the incorporation of the penA gene from commensal Neisseria spp. that are resistant to ceftriaxone. However, the mechanism of this mosaic penA generation is unknown.

Association of scan frequency with CGM-derived metrics and influential factors in adults with type 1 diabetes mellitus.

Introduction: This study aimed to investigate the association between scan frequency and intermittently scanned continuous glucose monitoring (isCGM) metrics and to clarify the factors affecting scan frequency in adults with type 1 diabetes mellitus (T1D).

Methods: We enrolled adults with T1D who used FreeStyle® Libre. Scan and self-monitoring of blood glucose (SMBG) frequency and CGM metrics from the past 90-day glucose data were collected.

NMR characterization of the structure of the intrinsically disordered region of human origin recognition complex subunit 1, hORC1, and of its interaction with G-quadruplex DNAs.

Human origin recognition complex (hORC) binds to the DNA replication origin and then initiates DNA replication. However, hORC does not exhibit DNA sequence-specificity and how hORC recognizes the replication origin on genomic DNA remains elusive. Previously, we found that hORC recognizes G-quadruplex structures potentially formed near the replication origin.

Recovery of hypoglycemic confidence using intermittently scanned continuous glucose monitoring among adults with type 1 diabetes with level 3 hypoglycemia: A prospective, single-center, single-arm study.

Aim: To investigate whether the FreeStyle Libre, an intermittent scanning continuous glucose monitoring (isCGM) system, influences confidence in managing hypoglycemia in adults with type 1 diabetes.

Materials And Methods: This longitudinal, observational study conducted at one facility included 121 adults with type 1 diabetes. Participants used the conventional finger-prick method for self-testing glucose before using isCGM.

ORC1 binds to cis-transcribed RNAs for efficient activation of replication origins.

Cells must coordinate the activation of thousands of replication origins dispersed throughout their genome. Active transcription is known to favor the formation of mammalian origins, although the role that RNA plays in this process remains unclear. We show that the ORC1 subunit of the human Origin Recognition Complex interacts with RNAs transcribed from genes with origins in their transcription start sites (TSSs), displaying a positive correlation between RNA binding and origin activity.
