Mitochondria are important organelles in eukaryotes that provide energy for cellular processes. Their function is highly conserved and depends on the expression of nuclear encoded genes and genes encoded in the organellar genome. Mitochondrial DNA replication is independent of the replication control of nuclear DNA and as such, mitochondria may behave as selfish elements, so they need to be controlled, maintained and reliably inherited to progeny. Phytopathogenic fungi meet with special environmental challenges within the plant host that might depend on and influence mitochondrial functions and services. We find that this topic is basically unexplored in the literature, so this review largely depends on work published in other systems. In trying to answer elemental questions on mitochondrial functioning, we aim to introduce the aspect of mitochondrial functions and services to the study of plant-microbe-interactions and stimulate phytopathologists to consider research on this important organelle in their future projects.
Placenta accreta spectrum disorders are a major risk factor for severe postpartum hemorrhage and maternal death worldwide, with a rapidly growing incidence in recent decades due to increasing rates of cesarean section. Placenta accreta spectrum disorders represent a complex surgical challenge, with the primary concern of massive obstetrical hemorrhagic sequelae and organ damage, occurring in the context of potentially significant anatomical and physiological changes of pregnancy. Most international obstetrical organizations have published guidelines on placenta accreta spectrum, embracing the creation of regionalized ‘Centers of Excellence’ in the diagnosis and management of placenta accreta spectrum, which includes a dedicated multidisciplinary surgical team. One mandatory criterion for these Centers of Excellence is the presence of a surgeon experienced in complex pelvic surgeries. Indeed, many institutions in the United States and worldwide rely on gynecologic oncologists in the surgical management of placenta accreta spectrum due to their experience and skills in complex pelvic surgery. Surgical management of placenta accreta spectrum frequently includes challenging pelvic dissection in regions with distortion of anatomy alongside large aberrant neovascularization. With a goal of definitive management through cesarean hysterectomy, surgeons require a systematic and thoughtful approach to promote prevention of urologic injuries, embrace measures to secure challenging hemostasis and, in selected cases, employ conservative management where indicated or desired. In this review recommendations are made for gynecologic oncologists regarding the management and important considerations in the successful care of placenta accreta spectrum disorders. Where required, gynecologic oncologists are encouraged to be proactively involved in the management of placenta accreta spectrum, not only intra-operatively, but also in the development of clinical protocols, guidelines, and pre-operative counseling of patients, as a ‘call if needed’ approach is suboptimal for this potentially major and life-threatening condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
