Endometriosis and adenomyosis are chronic gynecological conditions that significantly impact women's quality of life, leading to symptoms such as pelvic pain, dysmenorrhea, and infertility. Despite ongoing research, a definitive cure for these conditions remains elusive, and treatment often focuses on managing symptoms. Minimally invasive surgery is considered the gold standard for surgical management, but novel surgical techniques are continuously being developed to enhance outcomes.

Endometriosis represents one of the most common causes of life-impacting chronic pelvic pain and female infertility. Magnetic resonance imaging (MRI) plays an increasing role in the diagnosis and mapping of endometriosis, while diagnostic laparoscopy currently tends to be reserved for the patients with negative imaging results. The #Enzian, published in 2021, proposes a new comprehensive classification system of endometriosis, combining a complete staging of deep infiltrative endometriosis with the evaluation of peritoneal/ovarian/tubal localizations and the presence of adenomyosis.

Eukaryotic chromosomes typically end in 3' telomeric overhangs. The safeguarding of telomeric single-stranded DNA overhangs is carried out by factors related to the protection of telomeres 1 (POT1) protein in humans. Of the three POT1-like proteins in Caenorhabditis elegans, POT-3 was the only member thought to not play a role at telomeres.

Endometriosis is a chronic gynecological disease that impacts more than 176 million women worldwide, having a strong impact on psychological morbidity. This study aimed to evaluate the contribution of psychological morbidity, in women with endometriosis, taking into consideration the duration of the couple's relationship and the duration of the disease and also examined whether women's sexual satisfaction had an impact on their psychological morbidity (actor effect) and on their sexual partners' psychological morbidity (partner effect) and vice versa. Participants were 105 women and their partners, who answered the Hospital Anxiety and Depression Scale (HADS); Couple Satisfaction Index (CSI-4) and the Global Measure of Sexual Satisfaction (GMSEX).

Background: Laboratory skills training is an essential step before conducting minimally invasive surgery in clinical practice. Our main aim was to develop an animal model for training in clinically highly challenging laparoscopic duodenal atresia repair that could be useful in establishing a minimum number of repetitions to indicate safe performance of similar interventions on humans.

Materials And Methods: A rabbit model of laparoscopic duodenum atresia surgery involving a diamond-shaped duodeno-duodenostomy was designed.

To determine whether double-strand break (DSB) mobility enhances the physical search for an ectopic template during homology-directed repair (HDR), we tested the effects of factors that control chromatin dynamics, including cohesin loading and kinetochore anchoring. The former but not the latter is altered in response to DSBs. Loss of the nonhistone high-mobility group protein Nhp6 reduces histone occupancy and increases chromatin movement, decompaction, and ectopic HDR.

Topoisomerase II (Top2) is an essential enzyme that decatenates DNA via a transient Top2-DNA covalent intermediate. This intermediate can be stabilized by a class of drugs termed Top2 poisons, resulting in massive DNA damage. Thus, Top2 activity is a double-edged sword that needs to be carefully controlled to maintain genome stability.
