Article Abstract
An efficient and stability-indicating method has been developed and validated for the quantitative determination of tetrahydrofuran (THF), a hydrolytic degradation impurity, in Busulfan injectable pharmaceutical products by using gas chromatograph equipped with a liquid autosampler and a flame ionization detector. The chromatographic separation was performed on a fused silica capillary (Stabilwax; 60 m length × 0.32 mm i.d., 0.5 µm film thickness) column. The methodology was validated in accordance with regulatory guidelines. The proposed method was found to be specific, stable, precise, linear, accurate, robust, and rugged in the concentration range from 4 to 1,080 ppm for THF. The developed method was successfully applied to determine the THF content in Busulfan injectable pharmaceutical products.

[Icariin improves busulfan- and cyclophosphamide-induced reproductive function damage in male mice].

Objective: To comprehensively evaluate the effect of icariin in alleviating reproductive function damage (RFD) in male mice via in vitro and in vivo experiments.
Methods: We isolated Leydig cells from 60 KM male mice in vitro, and examined the toxic effect of icariin on the Leydig cells using Cell Counting Kit-8 (CCK-8). We equally randomized the mice into six groups: normal control, RFD model control (made by intraperitoneal injection of busulfan at 10 mg/kg combined with cyclophosphamide (CP) at 120 mg/kg), positive control, and low-, medium- and high-dose icariin.

Background: Busulfan and cyclophosphamide (Bu-Cy) is a widely used conditioning regimen for hematopoietic stem cell transplantation (HSCT) in the treatment of hematologic malignancies. To explore the exposure-efficiency relationships of Bu-Cy regimen and evaluate the necessity of relative therapeutic drug monitoring (TDM), we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to simultaneously quantify the busulfan and cyclophosphamide in human plasma.
Methods: A simple LC-MS/MS bioassay for simultaneous determination of busulfan and cyclophosphamide using isotope dilution internal standardization has been established.

Background: Recent studies have focused on investigating the role of cellular senescence in ovarian aging. Targeting cellular senescence has been proposed as a potential strategy to improve ovarian aging. p16 and p21 are classical molecules involved in mediating cellular senescence.

Objective: To investigate the effects of temsirolimus (Tem) and recombinant antimüllerian hormone (AMH) on fertility and the ovarian reserve when associated with chemotherapy.
Design: Thirty-seven female mice were assigned to one of three treatment groups: control group; chemotherapy group; and gonadoprotection group. Five weeks after treatment, the mice underwent ovarian stimulation and were mated with males to evaluate residual fertility.

Although isothiazolinones (ITs) are widely used as antimicrobials in various products, the understanding of their hazards remains incomplete. This study aimed to evaluate the adverse effects of ITs at human-relevant levels on the male mammal reproductive system. First, we employed testicular cells to determine all test ITs exerting relatively high toxicity, with 2-octyl-4-isothiazolin-3-one (OIT) exhibiting toxicity higher than that of other ITs.
