Hypoxia–ischemia is not an antecedent of most preterm brain damage: the illusion of validity

Developmental Medicine &Child Neurology, Volume 60, Issue 2, Page 120-125, February 2018., 2018
Brain injury in preterm newborn infants is often attributed to hypoxia–ischemia even when neither hypoxia nor ischemia is documented, and many causative speculations are based on the same assumption. We review human and animal study contributions with their strengths and limitations, and conclude that – despite all the work done in human fetal ...

Updated and New Perspectives on Diagnosis, Prognosis, and Therapy of Malignant Pheochromocytoma/Paraganglioma

Journal of Oncology, Volume 2012, Issue 1, 2012., 2012
Malignant pheochromocytomas/paragangliomas are rare tumors with a poor prognosis. Malignancy is diagnosed by the development of metastases as evidenced by recurrences in sites normally devoid of chromaffin tissue. Histopathological, biochemical, molecular and genetic markers offer only information on potential risk of metastatic spread.

How are the impacts of multiple anthropogenic drivers considered in marine ecosystem service research? A systematic literature review

Journal of Applied Ecology, Volume 61, Issue 6, Page 1212-1226, June 2024.
We have reviewed the current scientific knowledge on how human drivers affect coastal marine ecosystem services. We found that understanding the combined effects of different drivers and considering various time and space scales is still a pending issue. Ignoring multiple drivers, their interactions and time and space scales limits our understanding of
