In this work it was investigated the dependence of the correlation of folliculogenesis and endocrine function of ovarian tissue on the degree of structural damage and oocyte volume changes during ischemia. It was shown that after 2 hours of ischemia at 37 °C the morphological transformation of the structural components of the ovarian tissue were reversible. In case of restoration of blood flow conditions by heterotopic transplantation estradiol level of animals was 25,9 ± 5,18 pg/ml, progesterone--18,48 ± 3,69 ng/ml, significantly higher than the castrated animals-recipients. Supplement of the incubation medium by the fetal bovine serum lead to decreasing by 5-7% in the volume of oocytes of growing follicles during in ischemia and reduced steroidogenic function of ovarian tissue after perfusion. Increased time of the ischemia up to 4 hours was founded in irreversible morphological transformation, reduce the volume of oocytes by 40% and the formation of sclerosed tissue after transplantation of the ischemic fragments of ovarian tissue.

The surgical management of cancer patients wishing fertility preservation is multidisciplinary, involving surgeon, anesthetist, hematologist, and nursing and laboratory staff. Many oncology patients have a multitude of medical or surgical conditions that require careful planning of all therapy including surgical removal of reproductive material, either oocytes or ovarian tissue. The significant risks related to either transvaginal or abdominal surgery should be discussed and documented and the final decision to proceed must be balanced against the risks, including death.

Background: Tumor deposits (TDs) can impact proper staging of cancer, which is crucial for discussing prognosis and determining the appropriate treatment plan. Our study aimed to correlate how TDs influence prognosis of resected colorectal cancer (CRC) and how to optimize tumor-node-metastasis (TNM) staging with respect to TDs for clinical decision-making.
Methods: A retrospective analysis was performed on 611 patients with CRC treated in Jiangsu Cancer Hospital from January 1, 2010 to December 31, 2020 among whom 197 had TDs.

Aims: To explore physician-reported knowledge, use, and perceptions of genetic testing for advanced ovarian cancer management.
Materials & Methods: Gynecology/oncology specialists ( = 390) in the US, Europe, Canada, Japan, and Australia completed an online survey spanning March 2021 to April 2022.
Results: Physician-reported breast cancer gene mutation (BRCAm) testing rates increased over the 2 years before the survey; most patients underwent testing in the preceding 6 months.

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.

Background: The "Healthy China" initiative, along with advancements in technology for cancer diagnosis and treatment, has significantly enhanced outcomes for patients with gynecologic tumors. The trends of late marriage and delayed childbirth have led to an increasing number of women diagnosed with gynecologic cancers who are seeking fertility preservation in China. This issue is critical yet often overlooked in clinical practice.
