Study Objective: To estimate the association between preoperative beta-human chorionic gonadotropin (hCG) and progesterone levels, and success of linear salpingostomy in treatment of tubal pregnancy.
Design: Retrospective case control study (Canadian Task Force classification II-1).
Setting: Women's general hospital.
Patients: Three hundred five women undergoing laparoscopic linear salpingostomy for ectopic pregnancy.
Intervention: Examination of risk factors for surgical failure of salpingostomy by analyzing corresponding receiver operating curves.
Measurements And Main Results: In 305 women, intervention was successful in 272 and failed in 33, as assessed by either postoperative hemorrhage (16) or rising beta-hCG values (14); 3 women had both. Of 295 patients in whom beta-hCG was evaluated preoperatively, 149 (50.5%) had values of 1000 mU/ml. or less; 75% had progesterone levels of 10 ng/ml or below. No association was found between preoperative beta-hCG and progesterone levels and the success of linear salpingostomy.
Conclusion: Preoperative beta-hCG and progesterone levels are of no significance with regard to success of linear salpingostomy for treatment of tubal pregnancy.

Based on an exhaustive review, a theory was proposed with an immunoendocrine perspective on the reactivation of dormant Toxocara canis larvae in pregnant bitches and their transmission to fetuses through the placenta, or milk and colostrum to puppies. A historical review was carried out on the reactivation of dormant larvae of T. canis in pregnant bitches which suggested that larval reactivation of T.

Background: Para-phenylenediamine (PPD) is a crystalline solid that belongs to the aromatic amine group, widely used in the manufacturing of various dyes. PPD exhibits toxic effects on female hormone stability, ovarian function, and embryo development. Although studies have shown that PPD exposure can damage oocyte quality in female mice, research on its effects on male reproductive capability, particularly on human sperm quality and function, is limited.

Molecular recognition events between proteins drive biological processes in living systems. However, higher levels of mechanistic regulation have emerged, in which protein-protein interactions are conditioned to small molecules. Despite recent advances, computational tools for the design of new chemically induced protein interactions have remained a challenging task for the field.

The transglutaminase (TGMs) family plays a crucial role in regulating mammalian reproduction, yet its impact on poultry reproductive traits has not been extensively studied. In this study, we identified eight members of the TGMs family in chickens and examined the contributions of genetic variations of coagulation factor XIII A chain (F13A1), transglutaminase 4 (TGM4), and LOC101749664 to selective breeding in commercial layers through genetic variation response pattern analysis. Transcriptome data from various tissues of high- and low-egg-yielding Gushi chickens revealed significant positive correlations between the mRNA expression levels of TGM4 and F13A1 genes and egg production (P < 0.

Purpose: To evaluate the prognostic significance of progesterone receptor (PR) expression and the PIK3CA mutation status in HR+/HER2 - breast cancer patients, with the goal of screening patients who may derive the greatest benefit from PI3K-targeted therapy.
Methods: A retrospective analysis was conducted on 152 HR+/HER2 - breast cancer patients stratified by PR expression levels and PIK3CA mutation status. The study population was divided into groups on the basis of a median PR threshold of 50% and further subdivided by PIK3CA mutation status.
