In this study, the hypothesis that embryo development during routine IVF procedures is determined by the pre-ovulatory follicular fluid composition was tested. Follicular fluid from women with obesity ('obese') and a 'positive' or 'negative' IVF outcome was added during the in-vitro maturation of bovine oocytes. 'Negative' and 'obese' follicular fluid reduced bovine embryo development, compared with laboratory control embryo development (P < 0.05 or P < 0.1). The addition of follicular fluid also altered bovine blastocyst gene expression. Furthermore, LDHA and PPARGC1B gene expression differed between follicular fluid groups. Data suggest that pre-ovulatory follicular fluid can potentially affect oocyte developmental competence and embryo quality. Furthermore, the bovine model may be used as a screening tool.

Background: To investigate the impact of Melatonin on follicular oxidative stress and assisted reproductive technology (ART) outcomes in women with diminished ovarian reserve (DOR).

Method: We put 68 women with DOR who were going through ART into a randomized controlled trial. Starting on the fifth day of their menstrual cycle, we gave them either 3 mg of Melatonin or a placebo every day before stimulating their ovaries.

Exposure to 6PPD-Q induces dysfunctions of ovarian granulosa cells: Its potential role in PCOS.

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), an environmental pollutant derived from the ozonolysis of the widely used tire rubber antioxidant 6PPD, has been found to accumulate in air, dust, and water, posing significant health risks. While its reproductive toxicity in male organisms has been established, its effects on female reproductive health remain unclear. Polycystic ovary syndrome (PCOS), a common endocrine disorder in premenopausal women, is known to be influenced by environmental pollutants.

Introduction: Identifying non-invasive biomarkers which can predict the outcome of intracytoplasmic sperm injection (ICSI) is crucial, particularly in Germany where the challenges are intensified by the Embryo Protection Act. Recent research has highlighted biomarkers within the epidermal growth factor (EGF) family as central to follicular processes, although their predictive utility remains a subject of debate in the literature. Therefore, the primary objective of this study was to investigate the significance of amphiregulin concentrations in follicular fluid and gene expression in mural granulosa cells on oocyte maturation, fertilization, and embryo quality.

Bacterial pneumonia is a significant public health burden, contributing to substantial morbidity, mortality, and healthcare costs. Current therapeutic strategies beyond antibiotics and adjuvant therapies are limited, highlighting the need for a deeper understanding of the disease pathogenesis. Here, we employed single-cell RNA sequencing of 444,146 bronchoalveolar lavage fluid cells (BALFs) from a large cohort of 74 individuals, including 58 patients with mild (n = 22) and severe (n = 36) diseases as well as 16 healthy donors.
