During development, the cardiac alpha 1-adrenergic chronotropic response changes from positive in the neonate to negative in the adult. The negative chronotropic effect of alpha 1-adrenergic stimulation in the adult depends on maturation of sympathetic innervation and the presence of a pertussis toxin (PT)-sensitive guanine nucleotide-binding (G) protein. To examine the possibility of a develop...

Analyses of animal movement data have primarily focused on understanding patterns of space use and the behavioural processes driving them. Here, we analyzed animal movement data to infer components of individual fitness, specifically parturition and neonate survival. We predicted that parturition and neonate loss events could be identified by sudden and marked changes in female movement pattern...

background: maternal nutrition during pregnancy affects the birth weight of neonates. some of the undesirable pregnancy outcomes are linked to lower birth weights. this study aimed to assess the relationship between maternal dietary patterns, weight gain during pregnancy and nitric oxide (no), as an endothelial relaxing factor, and the possible effects on birth weight.materials and methods: at ...

purpose: to report an unusual case of orbitocranial meningioma presenting in a neonate. methods: case report results: a 1-day-old neonate was presented with severe proptosis of the left eye. ct scan and mri showed an extensive mass with involvement of left orbit and brain. discrete calcification could be seen on ct scan. the patient did not have any signs of neurofibromatosis and family history...

The evaluation and appropriate management of the critically ill neonate requires knowledge of the physiologic changes and life-threatening pathologies that may present during this time period. A broad systematic approach to evaluating the neonate is necessary to provide a comprehensive yet specific differential diagnosis for a presenting complaint or symptom. Efficient recognition and prompt ma...

We report a case of Eikenella corrodens sepsis associated with CSF pleocytosis in a very low birth weight neonate. A 1000-gram male neonate was born at 27-week gestation due to preterm labor. The patient presented with signs and symptoms of sepsis and was treated for suspected meningitis with intravenous ampicillin and gentamicin for 7 days, with cefotaxime added for three weeks. He had a norma...
