Functional characterization of dopamine and norepinephrine transport across the apical and basal plasma membranes of the human placental syncytiotrophoblast.

The human placenta represents a unique non-neuronal site of monoamine transporter expression, with pathophysiological relevance during the prenatal period. Monoamines (serotonin, dopamine, norepinephrine) are crucial neuromodulators for proper placenta functions and fetal development, including cell proliferation, differentiation, and neuronal migration. Accumulating evidence suggests that even a transient disruption of monoamine balance during gestation may lead to permanent changes in the fetal brain structures and functions, projecting into adulthood.

CHARACTERISTICS AND OUTCOMES OF METASTATIC SDHB AND SPORADIC PHEOCHROMOCYTOMA/PARAGANGLIOMA: AN NATIONAL INSTITUTES OF HEALTH STUDY.

Objective: Overall about 10 to 20% of pheochromocytomas/paragangliomas (PHEOs/PGLs) are metastatic, with higher metastatic potential observed in succinate dehydrogenase subunit B/fumarate hydratase (SDHB/FH)-related tumors. Due to the improved availability of biochemical and genetic testing and the frequent use of anatomical/functional imaging, there is currently a higher detection rate of metastatic PHEO/PGL.

Methods: A retrospective analysis of 132 patients (27 children, 105 adults) with metastatic PHEO/PGL diagnosed and treated from 2000 to 2014 was conducted.

Biochemical Testing After Pheochromocytoma Removal: How Early?

Pheochromocytomas are catecholamine-producing tumors with typical clinical presentation. Tumor resection is considered as an appropriate treatment strategy. Due to its unpredictable clinical behavior, biochemical testing is mandatory to confirm the success of tumor removal after surgery.

Combination antihypertensive therapy in clinical practice. The analysis of 1254 consecutive patients with uncontrolled hypertension.

The aim of the study was to analyze the clinical use of different types of combination therapy in a large sample of consecutive patients with uncontrolled hypertension referred to Hypertension Centre. We performed a retrospective analysis of combination antihypertensive therapy in 1254 consecutive patients with uncontrolled hypertension receiving at least triple-combination antihypertensive therapy. Among the most prescribed antihypertensive classes were renin-angiotensin blockers (96.

Genotype and tumor locus determine expression profile of pseudohypoxic pheochromocytomas and paragangliomas.

Pheochromocytomas (PHEOs) and paragangliomas (PGLs) related to mutations in the mitochondrial succinate dehydrogenase (SDH) subunits A, B, C, and D, SDH complex assembly factor 2, and the von Hippel-Lindau (VHL) genes share a pseudohypoxic expression profile. However, genotype-specific differences in expression have been emerging. Development of effective new therapies for distinctive manifestations, e.
