DNA methylation and demethylation link the properties of mesenchymal stem cells: Regeneration and immunomodulation.

Mesenchymal stem cells (MSCs) are a heterogeneous population that can be isolated from various tissues, including bone marrow, adipose tissue, umbilical cord blood, and craniofacial tissue. MSCs have attracted increasingly more attention over the years due to their regenerative capacity and function in immunomodulation. The foundation of tissue regeneration is the potential of cells to differentiate into multiple cell lineages and give rise to multiple tissue types.

Evaluation of Periodontal Status after Orthodontic Treatment: A Pilot Study on Patients with Stage IV/Grade C periodontitis.

Objective: To evaluate whether the periodontal status was affected in patients with stage IV/grade C periodontitis after orthodontic treatment.

Methods: Twenty-four patients with stage IV/grade C periodontitis who received combined periodontal and orthodontic treatment were included in this study. Probing depth (PD), bleeding on probing (BOP) and percentage of relative bone height (RBH%) were measured and calculated.

[Photosynthetic characteristics and active ingredients differences of Asarum heterotropoides var. mandshuricum under different light irradiance].

Chlorophyll content,leaf mass to per area,net photosynthetic rate and bioactive ingredients of Asarum heterotropoides var. mandshuricum,a skiophyte grown in four levels of solar irradiance were measured and analyzed in order to investigate the response of photosynthetic capability to light irradiance and other environmental factors. It suggested that the leaf mass to per area of plant was greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in the decrease of leaf mass to per area at every phenological stage.

DNA barcoding of , the most taxonomically complicated genus of Papaveraceae.

The genus is recognized as one of the most taxonomically challenging plant taxa. It is mainly distributed in the Himalaya-Hengduan Mountains, a global biodiversity hotspot. To date, no effective solution for species discrimination and taxonomic assignment in has been developed.

Role of downregulated miR-133a-3p expression in bladder cancer: a bioinformatics study.

It has been discovered that miR-133a-3p acts as a tumor suppressor in bladder cancer (BC). Nevertheless, the function of miR-133a-3p in BC remains unclarified. Thus, we carried out this study to validate the expression of miR-133a-3p in BC and provide insights into the molecular mechanism underlying it.

[Identification of antler powder components based on DNA barcoding technology].

In order to authenticate the components of antler powder in the market, DNA barcoding technology coupled with cloning method were used. Cytochrome c oxidase subunit I (COI) sequences were obtained according to the DNA barcoding standard operation procedure (SOP). For antler powder with possible mixed components, the cloning method was used to get each COI sequence.

[Advances of NIR spectroscopy technology applied in seed quality detection].

Near infrared spectroscopy (NIRS) technology developed fast in recent years, due to its rapid speed, less pollution, high-efficiency and other advantages. It has been widely used in many fields such as food, chemical industry, pharmacy, agriculture and so on. The seed is the most basic and important agricultural capital goods, and seed quality is important for agricultural production.

[Identification of peucedani radix, peucedani decursivi radix and its adulterants using ITS2 sequence].

In order to identify Peucedani Radix, Peucedani Decursivi Radix and their adulterants, the internal transcribed spacer 2 (ITS2) regions of Peucedani Radix, Peucedani Decursivi Radix and their adulterants were amplified and bidirectionally sequenced based on the Principles for Molecular Identification of Traditional Chinese Materia Medica Using DNA Barcoding, which has been promulgated by Chinese Pharmacopoeia Commission. Sequences were analyzed and assembled by Codon Code Aligner V3. 7.

[Research on genetic stability to American ginseng introduced into China for 30 years].

To study the genetic stability of Panax quinquefolium after introduced into China for 30 years, the samples of P. quinquefolium from 14 regions of China were studied. RAPD molecular marker technology was applied in this research, and POPGEN32 data analysis and NTSYS2.

Since the research of molecular identification of Chinese Materia Medica (CMM) using DNA barcode is rapidly developing and popularizing, the principle of this method is approved to be listed in the Supplement of the Pharmacopoeia of the People's Republic of China. Based on the study on comprehensive samples, the DNA barcoding systems have been established to identify CMM, i.e.

[Identification of gentianae macrophyllae radix using the ITS2 barcodes].

DNA barcoding is a rapidly developing frontier technology in the world and will be useful in promoting the quality control and standardization of traditional Chinese medicine. Until now, many studies concerning DNA barcoding have focused on leaf samples but rarely on Chinese herbal medicine. There are three issues involved in DNA barcoding for traditional Chinese medicinal materials: (1) the extraction methods for total DNA of the rhizomes of the medicinal materials; (2) intra-specific variation among samples from different places of origin; (3) accuracy and stability of this method.
