Background: Preeclampsia is a severe hypertensive disorder in pregnancy that causes preterm delivery, maternal and fetal morbidity, mortality, and life-long sequelae. Understanding the pathogenesis of preeclampsia is a critical first step toward protecting mother and child from this syndrome and increased risk of cardiovascular disease later in life. However, effective early predictive tests and therapies for preeclampsia are scarce.

Pre-eclampsia is a leading cause of maternal and fetal morbidity and mortality. Characterised by the onset of hypertension and proteinuria in the second half of pregnancy, it can lead to maternal end-organ injury such as cerebral ischemia and oedema, pulmonary oedema and renal failure, and potentially fatal outcomes for both mother and fetus. The causes of the different maternal end-organ phenotypes of pre-eclampsia and why some women develop pre-eclampsia condition early in pregnancy have yet to be elucidated.

Tissue insults in response to inflammation, hypoxia and ischemia are accompanied by the release of ATP into the extracellular space. There, ATP modulates several pathological processes, including chemotaxis, inflammasome induction and platelet activation. ATP hydrolysis is significantly enhanced in human pregnancy, suggesting that increased conversion of extracellular ATP is an important anti-inflammatory process in preventing exaggerated inflammation, platelet activation and hemostasis in gestation.

Open, reproducible, and replicable research practices are a fundamental part of science. Training is often organized on a grassroots level, offered by early career researchers, for early career researchers. Buffet style courses that cover many topics can inspire participants to try new things; however, they can also be overwhelming.

Background: Acetic acid is a short-chain fatty acid that has demonstrated biomedical potential as a dietary therapeutic agent for the management of chronic and metabolic illness comorbidities. In human beings, its consumption may improve glucose regulation and insulin sensitivity in individuals with cardiometabolic conditions and type 2 diabetes mellitus. Published clinical trial evidence evaluating its sustained supplementation effects on metabolic outcomes is inconsistent.

Article Synopsis
  • The study investigates how human somatic cells can be reprogrammed into induced pluripotent stem cells, mimicking early embryo development, to better understand the molecular mechanisms involved.
  • Researchers used single-cell transcriptomics to analyze the reprogramming process of human dermal fibroblasts, discovering that it follows two distinct pathways toward primed and naive pluripotency.
  • The study highlights the importance of trophectoderm-specific regulatory factors in this process, leading to the successful creation of induced trophoblast stem cells that share similarities with those found in early human embryos.

Synopsis of recent research by authors named "Daniela S Valdes"

  • - Daniela S Valdes's research primarily focuses on preeclampsia, exploring its pathophysiology and potential therapeutic interventions, with a specific emphasis on senescent syncytiotrophoblast secretion and the effects of ATP modulation in the placenta during pregnancy.
  • - Her recent studies utilize advanced methodologies, such as single-cell and spatial omics, to investigate the maternal end-organ injury phenomena associated with preeclampsia, ultimately aiming to elucidate the mechanisms behind early onset and variability of the condition in different women.
  • - Valdes also addresses broader scientific practices, advocating for open and reproducible research methodologies while contributing to dietary studies that assess the effects of acetic acid on metabolic health, indicating her versatile approach to research in both reproductive and nutritional health sciences.
