Article Synopsis
  • The study assessed changes in population structure, reproductive performance, inbreeding, and genetic diversity in Charolais cattle using genealogical data from the Ecuadorian Charolais Association.
  • It divided the data into five time periods, analyzing factors like pedigree completeness, generation interval, inbreeding levels, and effective population size with specific software.
  • Results showed a decrease in pedigree completeness and generation interval over time, an increase in inbreeding, and a progressive loss of genetic diversity, but female reproductive efficiency improved, suggesting a need for genetic resource management to address inbreeding issues.

Introduction: Intradialytic hypertension (IDH) is a poorly understood phenomenon with no consensus on its definition, etiology, or related factors, and there is limited evidence on its consequences.

Objective: To determine the prevalence of IDH according to different definitions in hemodialysis (HD) units, with different clinical practices and assessment of possible events after 18 months have passed.

Materials And Methods: A cross-sectional observational study was conducted in 2 HD units, including all prevalent patients from March 2021 to September 2022.

Objective: Management of endometrial cancer is advancing, with accurate staging crucial for guiding treatment decisions. Understanding sentinel lymph node (SLN) involvement rates across molecular subgroups is essential. To evaluate SLN involvement in early-stage (International Federation of Gynecology and Obstetrics 2009 I-II) endometrial cancer, considering molecular subtypes and new European Society of Gynaecological Oncology (ESGO) risk classification.

Biomarkers for cancer immunotherapy are an unmet medical need. The group of Daniela Thommen at the NKI recently reported on novel methodologies based on short-term cultures of patient-derived tumor fragments whose cytokine concentrations in the supernatants and activation markers on infiltrating T cells were associated with clinical response to PD-1 blockade. We set up a similar culture technology with tumor-derived fragments using mouse tumors transplanted into syngeneic immunocompetent mice to test an agonist anti-CD137 mAb and its combinations with anti-PD-1 and/or anti-TGF-β.
