Hypopituitarism is the inability of the anterior pituitary gland to properly supply the hormone levels. When this disease affects all the hormones produced by the anterior pituitary, it is called panhypopituitarism (PHP). Since pituitary-derived hormones directly influence fertility, often the assisted reproduction techniques are the only option to PHP women have a full-term pregnancy.

The pivotal role of human endometrial stromal cells (hESCs) in the development of endometriosis lies in their ability to adopt a pro-invasive and proinflammatory profile upon migration to areas outside the uterus. However, the molecular mechanisms involved in these events remain unclear. In this study, we investigated how angiotensin II (Ang II) affects the plasminogen-plasmin system in hESCs, and the mechanisms underlying cell proliferation, migration, matrix degradation, and inflammation.

The pathophysiology of recurrent pregnancy loss (RPL) involves deficiencies in the proliferation and migration capacities of endometrial stromal cells (hESCs), which impair embryo implantation and development. Since animal venoms are rich source of bioactive molecules, we aimed to characterize the cytoprotective effects of Lonomia obliqua venom on hESCs. hESCs were isolated from endometrial biopsies and the mechanisms of L.

Aim: In this study, we investigated how platelets and aorta contribute to the creation and maintenance of a prothrombotic state in an experimental model of postmenopausal hypertension in ovariectomized rats.

Methods: Bilateral ovariectomy was performed in both 14-week-old female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats. The animals were kept in phytoestrogen free diet.

The impact of (CT) infection on female's fertility is not completely established yet, since the level of evidence associating these factors is still weak. Hence, the goal of the present review is to contribute to a better elucidation of this matter. The electronic database chosen was the Medline/PubMed, with the last survey on May 11, 2021.

Aims: Accidental contact with the Lonomia obliqua caterpillar is a common event in southern Brazil. Envenomed victims present consumption coagulopathy, which can evolve to acute kidney injury (AKI). In the present study, we searched for AKI biomarkers and changes in molecular pathway signatures through urine proteomic analysis.

Kallikrein-kinin system (KKS) is involved in vascular reactivity and inflammatory response to cytotoxic drugs. Since cisplatin is a widely used chemotherapy and its cytotoxic mechanism can trigger inflammation and oxidative damage, in this work we evaluated the role of KKS in an animal model of cisplatin-induced ovarian toxicity. Biomarkers of ovarian stem cells, activity of KKS, inflammation and oxidative damage were measured in ovarian tissue of C57BL/6 female mice treated with vehicle or cisplatin (2.

Objective: The aim of this study was to investigate the efficacy of protocols for mice ovary cryopreservation to compare the differences in Mouse Vasa Homologue expression (a germline cell marker) and ovarian viability after vitrification or slow freezing.

Methods: Female CF1 mice aged 40-45 days were randomly divided into three groups: Control, vitrification or slow freezing. Their ovaries were surgically removed, rinsed in saline solution and cryopreserved.

Some biomaterial scaffolds can positively interfere with tissue regeneration and are being developed to successfully repair the tissue function. The possibility of using epithelial cells combined with biomaterials appears to be a new option as therapeutic application. This combination emerges as a possibility for patients with Mayer-Rokitansky-Kuster-Hauser syndrome which requires vaginal repair and can be performed with tissue-engineered solution containing cells and biomaterials.

Background: Lonomia obliqua venom is nephrotoxic and acute kidney injury (AKI) is the main cause of death among envenomed victims. Mechanism underlying L. obliqua-induced AKI involves renal hypoperfusion, inflammation, tubular necrosis and loss of glomerular filtration and tubular reabsorption capacities.

Background: Mesenchymal stromal cells (MSCs) are being investigated as a potential alternative for cellular therapy. This study was designed to compare the biological characteristics of MSCs isolated from amniotic membrane (A-MSCs), chorionic membrane (C-MSCs), placental decidua (D-MSCs) and umbilical cord (UC-MSCs) to ascertain whether any one of these sources is superior to the others for cellular therapy purposes.

Methods: MSCs were isolated from amniotic membrane, chorionic membrane, umbilical cord and placental decidua.

Glucocorticoids and immunosuppressive drugs are commonly used to treat inflammatory disorders, such as inflammatory bowel disease (IBD), and despite a few improvements, the remission of IBD is still difficult to maintain. Due to their immunomodulatory properties, mesenchymal stem cells (MSCs) have emerged as regulators of the immune response, and their viability and activation of their migratory properties are essential for successful cell therapy. However, little is known about the effects of immunosuppressant drugs used in IBD treatment on MSC behavior.

Aim: To investigate the therapeutic effects of mesenchymal stem cells (MSCs) transplanted intraperitoneally and intravenously in a murine model of colitis.

Methods: MSCs were isolated from C57BL/6 mouse adipose tissue. MSC cultures were analyzed according to morphology, cellular differentiation potential, and surface molecular markers.

Recurrent pregnancy loss (RPL) is defined as the occurrence of two or more consecutive pregnancy losses. It is an important reproductive condition with a complex etiology. In approximately 50% of RPL cases an explanation for the cause is not found and they are therefore classified as idiopathic RPL.

Background: This cross-sectional, nested cohort study assessed Female Sexual Function Index (FSFI) scores in postmenopausal women with breast cancer receiving primary chemotherapy.

Methods: The FSFI questionnaire was administered to 24 postmenopausal women one month after diagnosis of breast cancer (post-diagnosis group) and one month after completion of the first cycle of primary anthracyclin-based chemotherapy (post-chemotherapy group). Scores were compared to those of 24 healthy postmenopausal women seeking routine gynecological care (control group).

Aim: To investigate the interaction between mesenchymal stem cells (MSCs) and bone grafts using two different cultivation methods: static and dynamic.

Methods: MSCs were isolated from rat bone marrow. MSC culture was analyzed according to the morphology, cell differentiation potential, and surface molecular markers.

Pyoderma gangrenosum (PG) is a rare, chronic, often destructive, inflammatory skin disease in which a painful nodule or pustule breaks down to form a progressively enlarging ulcer. There are only 4 reported cases of postlaparoscopic PG and the purpose of this case report is to describe a patient found to have the disease after elective laparoscopy. Although rare, the occurrence of PG after surgery, even where incisions are small such as in laparoscopic surgery, is a diagnosis that cannot be neglected, especially due to the high morbidity, which increases if the diagnosis is not made and the patient is subjected to debridement.

Betacellulin (BTC), a ligand of the epidermal growth factor receptor, has been shown to promote growth and differentiation of pancreatic β-cells and to improve glucose metabolism in experimental diabetic rodent models. Mesenchymal stem cells (MSCs) have been already proved to be multipotent. Recent work has attributed to rat and human MSCs the potential to differentiate into insulin-secreting cells.

Purpose: the objective of the present study was the development of the Brazilian Portuguese version of Endometriosis Health Profile Questionnaire (EHP-30), the cross-cultural adaptation to Brazil and the evaluation of EHP-30 Portuguese psychometric measures in a Brazilian sample.

Methods: the original instrument in English was translated into Portuguese following international guidelines, going through all stages of translation, back-translation and comparison of the versions for cross-cultural adaptation, face and content validity. A sample of 54 patients with endometriosis was used for internal consistency analyses using the Cronbach alpha.
