BACKGROUND: Noninvasive ventilation is increasingly used in very-low-birth-weight infants (VLBWI) to reduce complications that occur with invasive ventilation. However, the physiological effects of synchronization during noninvasive nasal intermittent mandatory ventilation (IMV) have not been tested in VLBWI immediately after extubation. OBJECTIVE: We aimed to study the short-term effects of synchronized nasal IMV (S-NIMV) compared to nonsynchronized nasal IMV (NIMV) on ... إقراء المزيد

Moringa oleifera is a fast growing tree under field conditions. A micropropagation protocol of M. oleifera was established, and effects of salinity and ventilation on fast growing cultured plant materials were studied. Efficient shoot formation and multiplication were obtained when nodal or shoot tip explants were cultured on MS medium supplemented with 2.5 μM 6-benzylaminopurine (BAP) at mild ventilation conditions. ... إقراء المزيد
