In addition, Dr. Speer is interested in the clinical outcome of extremely low birth weight newborns.ddition, Dr. Speer is interested in the clinical outcome of extremely low birth weight newborns.
Marian Evinger, PhD is an Associate Professor of Pediatrics, Pharmacology and Neurosciences. Her research interests in neonatology include the influence of hypoxia on synthesis and release of neuroendocrine transmitters and factors in cell culture models of acute perinatal hypoxic exposure. One current project examines the stimulatory influence of reduced oxygen exposure on the production of opioid peptides and endogenous opioids in adrenal medullary-derived pheochromocytoma cell lines. A related project evaluates the effects of hypoxia on inflammatory cytokine synthesis and release in this model. These studies complement original observations from this laboratory and division that hypoxia rapidly stimulates neonatal adrenaline release by markedly activating transcription of the gene for the adrenaline-synthesizing enzyme PNMT, acting through a hypoxia response element encoded in the proximal promoter of this catecholamine gene. Her investigations employ molecular, biochemical and cellular approaches to examine transcriptional, translational and stimulus-coupled release of neurotransmitters, neuroactive peptides and opioids from perinatal adrenal medulla as a mechanism for coping with the metabolic and physiologic stresses resulting from acute hypoxia.
Farah Hussain, MD - Dr. Hussain joined our program in July 2016. Dr Hussain, a graduate of Albany Medical College, joins us from her Pediatric Residency at Baystate Medical Center in Springfield Massachusetts.
