Systematic comparison of tools used for mA mapping from nanopore direct RNA sequencing.

N6-methyladenosine (m6A) has been increasingly recognized as a new and important regulator of gene expression. To date, transcriptome-wide m6A detection primarily relies on well-established methods using next-generation sequencing (NGS) platform. However, direct RNA sequencing (DRS) using the Oxford Nanopore Technologies (ONT) platform has recently emerged as a promising alternative method to study m6A.

Systematic calibration of epitranscriptomic maps using a synthetic modification-free RNA library.

Recent years have witnessed rapid progress in the field of epitranscriptomics. Functional interpretation of the epitranscriptome relies on sequencing technologies that determine the location and stoichiometry of various RNA modifications. However, contradictory results have been reported among studies, bringing the biological impacts of certain RNA modifications into doubt.

In adjuvant-induced arthritic rats, acupuncture analgesic effects are histamine dependent: potential reasons for acupoint preference in clinical practice.

This study investigated whether immediate acupuncture effects in the acupoint are histamine dependent. Both histamine injection and manual acupuncture stimulation increased the pain threshold (PT) after treatment compared with the model group (P < 0.01), producing an analgesic effect.

[Acupoint-injection of histamine induced analgesic effect in acute adjuvant-induced-arthritis rats].

Objective: To observe the activation effect of histamine on mast cells in the acupoint area and its analgesic effects similar to acupuncture stimulation, so as to reveal the underlying mechanism of acupoint injection therapy.

Methods: A total of 60 SD rats were divided into control, model, normal saline (NS), histamine-injection and acupuncture groups (12 rats/group). Acute adjuvant-induced-arthritis (AIA) model was duplicated by injection of complete Freunds' Adjuvant (0.
