Dnmt1 is required for the development of auditory organs via cell cycle arrest and Fgf signalling.

Objectives: To explore the role of DNA methyltransferase 1 (DNMT1) in the development of auditory system using zebrafish as experimental model.

Methods: Morpholino oligonucleotide was used to induce Dnmt1 deficiency. RNA sequencing, in situ hybridization (ISH), whole genomic bisulfide sequencing (WGBS) and immunostaining were used to investigate the morphologic alterations and mechanisms.

Silencing MR-1 Protects against Myocardial Injury Induced by Chronic Intermittent Hypoxia by Targeting Nrf2 through Antioxidant Stress and Anti-Inflammation Pathways.

Background: Patients with obstructive sleep apnea hypopnea syndrome (OSAHS) often have cardiac insufficiency mainly due to hypoxia/reperfusion injury caused by chronic intermittent hypoxia (CIH). Inflammation and oxidative stress are involved in the cardiovascular events of OSAHS patients. Studies have found that myofibrillation regulator-1 (MR-1) participates in the pathological process of OSAHS-induced myocardial injury, but the specific mechanism is still unclear.

Preliminary comparison of the efficacy of several surgical treatments based on maxillomandibular advancement procedures in adult patients with obstructive sleep apnoea: a systematic review and network meta-analysis.

Purpose: To evaluate the efficacy of eight different surgical treatments based on maxillomandibular advancement (MMA), which has emerged in recent years, for adult obstructive sleep apnoea (OSA) patients.

Methods: The literature was searched from January 2010 to May 2020 for studies of adult OSA patients with different types of MMA procedures to perform a network meta-analysis. The outcomes were changes in the apnoea-hypopnoea index (AHI), the lowest pulse oxygen saturation (SpO min) and the Epworth Sleepiness Scale (ESS).

Bioconversion of Gibberellin Fermentation Residue into Feed Supplement and Organic Fertilizer Employing Housefly (Musca domestica L.) Assisted by Corynebacterium variabile.

The accumulation of a considerable quantity of gibberellin fermentation residue (GFR) during gibberellic acid A3 (GA3) production not only results in the waste of many resources, but also poses a potential hazard to the environment, indicating that the safe treatment of GFR has become an urgent issue for GA3 industry. The key to recycle GFR is converting it into an available resource and removing the GA3 residue. To this end, we established a co-bioconversion process in this study using house fly larvae (HFL) and microbes (Corynebacterium variabile) to convert GFR into insect biomass and organic fertilizer.
