Construction of induced pluripotent stem cell line (CSBZZUi002-A) from the fibroblast cells of a healthy female.

We recruited a healthy 44-year-old female and obtained her skin fibroblasts. Subsequently, the induced pluripotent stem cell line was successfully established using non-integrated reprogramming technology. The cell line had a normal karyotype and has been confirmed to have good pluripotency through the detection of pluripotency markers and detection of teratoma formation.

Generation of an induced pluripotent stem cell line (CSBZZUi001-A) from a female Alzheimer's patient carrying the PSEN1 709 T > C heterozygous mutation.

Pluripotent stem cells were generated through the electroporation of episomal plasmids, containing crucial reprogramming factors, into skin fibroblasts extracted from a female Alzheimer's patient harboring the PSEN1 709 T > C (p.Phe237Leu) heterozygous mutation. The pluripotent stem cells exhibit a normal karyotype and express pivotal stem cell markers including TRA-1-60, Nanog, SOX2, and OCT4.

Neurotransmitter accumulation and Parkinson's disease-like phenotype caused by anion channelrhodopsin opto-controlled astrocytic mitochondrial depolarization in substantia nigra pars compacta.

Parkinson's disease (PD) is a mitochondria-related neurodegenerative disease characterized by locomotor deficits and loss of dopaminergic (DA) neurons in the (SNc). Majority of PD research primarily focused on neuronal dysfunction, while the roles of astrocytes and their mitochondria remain largely unexplored. To bridge the gap and investigate the roles of astrocytic mitochondria in PD progression, we constructed a specialized optogenetic tool, mitochondrial-targeted anion channelrhodopsin, to manipulate mitochondrial membrane potential in astrocytes.

A sensitive mitochondrial thermometry 2.0 and the availability of thermogenic capacity of brown adipocyte.

The temperature of a living cell is a crucial parameter for cellular events, such as cell division, gene expressions, enzyme activities and metabolism. We previously developed a quantifiable mitochondrial thermometry 1.0 based on rhodamine B methyl ester (RhB-ME) and rhodamine 800 (Rh800), and the theory for mitochondrial thermogenesis.

Donor BMSC-derived small extracellular vesicles relieve acute rejection post-renal allograft through transmitting Loc108349490 to dendritic cells.

Bone marrow-derived mesenchymal stem cell (BMSC)-derived small extracellular vesicles (sEVs) are potent candidates for the suppression of acute rejection post-renal allograft and have been reported to halt dendritic cells (DCs) maturation. However, whether BMSC-derived sEVs mitigate acute rejection post-renal allograft by targeting DCs is still unclear. In this study, donor BMSC-derived sEVs (sEVs) relieved the inflammatory response and suppressed mature DCs (mDCs) location in kidney grafts, and increased regulatory T (Treg) cell population in the spleens of the rats that underwent kidney allograft.

A novel nonsense variant of the AGXT identified in a Chinese family: special variant research in the Chinese reference genome.

Background: Primary hyperoxaluria(PH)is a rare autosomal recessive genetic disease that contains three subtypes (PH1, PH2 and PH3). Approximately 80% of PH patients has been reported as subtype PH1, this subtype of PH has been related to a higher risk of renal failure at any age. Several genetic studies indicate that the variants in gene AGXT are responsible for the occurrence of PH1.

Preparation of osthole-loaded nano-vesicles for skin delivery: Characterization, in vitro skin permeation and preliminary in vivo pharmacokinetic studies.

The main objective of the present research was to evaluate the flexible nano-vesicles for transdermal delivery of osthole. The nano-vesicles were formulated, characterized and evaluated for their physicochemical properties, in vitro skin permeation and in vivo plasma concentration. The encapsulation efficiency of osthole in ethosome and transfersome was measured to be 83.

Suppression of spermatogenesis by testosterone undecanoate-loaded injectable in situ-forming implants in adult male rats.

We have investigated the feasibility of administration of testosterone undecanoate (TU)-loaded injectable in situ-forming implant (ISFI) for contraception in adult male Sprague-Dawley rats. Male rats were treated with vehicle, TU-loaded ISFIs (540, 270 and 135 mg TU kg-1 ) or TU injections (45 mg TU kg-1 every 30 days) for 120 days. Fertility tests served for determining infertility or restoration of fertility in treated rats.

[Biological limit value for occupational exposure to N, N-dimethylacetamide].

Objective: To establish Biological Limit Value (BLV) for N, N-dimethylacetamide (DMAC).

Method: 201 workers in 3 spandex factories exposed to DMAC were recruited. Air samples were collected using personal air samplers, and urine samples from each works were collected at the end of shift at end of workweek.

[The analysis of urinary N-methylacetamide by GC-NPD with a direct injection].

Objective: To establish a method to detect N-methylacetamide (NMAC) concentration in urine of workers occupationally exposed to NMAC with directly injecting the sample into capillary gas chromatography.

Methods: After frozen urine samples were isolated from precipitation by centrifugation, the aliquot of supernatant was pretreated by protein precipitation with dilution of methanol. The methanol supernatant was separated by Polyethylene Glycol (PEG) capillary columns and detected by nitrogen phosphorous detector (NPD).

[The impact of N, N-dimethylacetamide on the health of workers].

Objective: To explore the hepatic toxicity and the exposure biomarkers of N, N-Dimethylacetamide.

Methods: One hundred forty five objects were chosen by stratified random sampling method. The investigation was performed using questionnaire and physical examination.

[Determination of trimethyltin chloride in urine by headspace-gas chromatography].

Objective: To establish a detection method for trimethyltin chloride in urine by the Head space-GC.

Method: After derivatizing trimethyltin chloride, the urines was separated by the head space-gc, and then the trimethyltin chloride detected qualitatively and quantificationally.

Results: In the concentration range of 0.

[Investigation on dermal contamination among workers occupationally exposed to dimethylformamide].

Objective: To establish a method for the determination of dimethylformamide (DMF) and investigate dermal contamination and absorption among workers occupationally exposed to DMF.

Method: 37 workers exposed to DMF were divided randomly into two groups. DMF was washed down by isopropyl alcohol in A group (16 workers) and water in B group(21 workers).

Objective: To study the optimal process of the extraction of indirubin from Isatis indigotica Fort.

Methods: The process was studied by supersonic extraction, refluxing and orthogonal design with the content of indirubin as the detective marker. Then the extraction of indirubin with supersonic extraction and other methods were compared basing on the yield of extracts.
