Published: December 2023

In the present study, we have sequenced, annotated and characterized the complete mitogenome of Li, Liao & Shen, 2022, which is an endemic minnow to Hainan Province, China. The entire mitogenome size is 16,545 bp, containing 37 genes coding for 13 mitochondrial proteins, 22 tRNAs, 2 rRNAs, and one putative control region. It has the typical fish mitochondrial gene arrangement, though with 9 gene overlaps and 17 intergenic spacers scattering throughout the mitogenome, and a high A + T bias (60.8%) comparing to other Cyprinids. ATG is used as the start codon in most mitochondrial protein coding genes (PCGs) except for which uses GTG, whereas the canonical TAA/TAG are prevailing stop codons except for , , and . Phylogenetic analyses with other reported species from Tanichyidae were conducted using IQ-TREE and MrBayes, based on the concatenated 13 PCGs. The results clustered with the newly described Li Bohlen & Liao, 2022, and proved the reciprocally monophyletic relationship between Chinese and Vietnamese .

Background: Venetoclax + azacitidine is a frontline treatment for older adult acute myeloid leukemia (AML) patients and a salvage therapy for relapsed/refractory patients who have been treated with intensive chemotherapy. While this is an important treatment option, many patients fail to achieve complete remission and of those that do, majority relapse. Leukemia stem cells (LSCs) are believed to be responsible for AML relapse and can be targeted through oxidative phosphorylation reduction.

Objective: To assess the feasibility of first polar body transfer (PB1T) combined with preimplantation mitochondrial genetic testing for blocking the transmission of a pathogenic mitochondrial DNA 8993T>G mutation.

Methods: A Chinese family affected with Leigh syndrome which had attended the Reproductive Medicine Centre of the First Affiliated Hospital of Anhui Medical University in September 2021 was selected as the study subject. Controlled ovarian hyperstimulation was carried out for the proband after completing the detection of the mitochondrial DNA 8993T>G mutation load among the pedigree members.

Ethnopharmacological Relevance: The Chinese herbal Plantaginis Herba (PL) is one of the most widely used plants for both medicinal and dietary purposes. Plantaginis Herba is the main medicine used in a traditional Chinese prescription called Cheqiancao decoction, and it is known for its liver and kidney protective properties.

Aim Of The Study: The aim of the present study was to explore the interventions and mechanisms of PL in ADR nephropathy by performing an integrated analysis of in vitro and in vivo experiments.

[Effect of "Zhibian" (BL54)-toward-"Shuidao" (ST28) acupuncture on reproductive function in mice with asthenozoospermia based on mitochondrial apoptosis].

College of Acupuncture-Moxibustion and Tuina, Chengdu University of TCM, Chengdu 610075, Sichuan Province, China; Second Clinical College, Shanxi University of CM, Jinzhong 030619.

Objective: To observe the effects of the "Zhibian" (BL54)-toward-"Shuidao" (ST28) acupuncture on key regulatory factors during mitochondrial apoptosis of testicular tissue in asthenozoospermia mice, and explore the potential mechanism of the protective effect of acupuncture on reproductive function.

Methods: Thirty C57BL/6 male mice were randomly divided into a blank group, a model group and an acupuncture group, 10 mice in each group. In the model and the acupuncture groups, the intraperitoneal injection of cyclophosphamide (30 mg•kg•d) was delivered for 7 days to prepare the asthenozoospermia model.
