In vitro effect of hCG on cryptorchid patients' gubernacular cells: a predictive model for adjuvant personalized therapy.

Background: Cryptorchidism is the absence of one or both testicles in the scrotum at birth, being a risk factor for testis cancer and infertility. The most effective method to treat cryptorchidism is orchiopexy, followed by human chorionic gonadotropin (hCG) therapy; however, a portion of treated patients do not show a significant improvement in testis volume and vascularization after adjuvant therapy.

Methods: In this study, we generated an in vitro model to predict the patient response to hCG by cultivating and treating primary cells derived from five cryptorchid patients' biopsies of gubernaculum testis, the ligament that connects the testicle to the scrotum.

Platelet-rich plasma effects on in vitro cells derived from pediatric patients with andrological diseases.

Undescended testis and testicular torsion represent two frequent andrological diseases that affect the pediatric age. Despite these testicular disorders having different causes, they both negatively influence fertility in adulthood mainly due to the accumulation of reactive oxygen species (ROS), which represents the primary molecular damage underlying their long-term effects. The gold standard of treatment for both pathologies is surgery; however, it cannot guarantee an optimal fertility outcome in all clinical cases, underscoring the need to identify effective adjuvant therapies that may target the augmented ROS levels.

Long-Term Follow Up in Anti-Contactin-1 Autoimmune Nodopathy.

Objective: To analyze long-term clinical and biomarker features of anti-contactin-1 (CNTN1) autoimmune nodopathy (AN).

Methods: Patients with anti-CNTN1 autoimmune nodopathy detected in our laboratory from which clinical information was available were included. Clinical features and treatment response were retrospectively collected.

In vitro obtainment of stem-like cells from gubernaculum testis biopsies of cryptorchid pediatric patients.

Testicular descent is a crucial event in male sexual development, and alterations in this process during gestation can lead to reduced fertility in adulthood. Cryptorchidism, i.e.

Joint modeling of longitudinal and survival data for the evaluation of the impact of irrigation systems on the time until the occurrence of phoma leaf spot in Arabica coffee plants.

Background: The coffee crop is prominent in Brazilian agriculture, making the country a global power in this area. One of the main concerns in the coffee sector is disease, which can affect coffee productivity and quality. Thus, it is important to evaluate the factors that may affect coffee quality and thus enhance the development of strategies to reduce coffee losses and costs and optimize production.
