Delayed Cord Clamping for 45 Seconds in Very Low Birth Weight Infants: Impact on Hemoglobin at Birth and Close to Discharge.

Objectives: To assess the impact of delayed cord clamping (DCC) for 45 seconds on hemoglobin at birth and close to discharge in very low birth weight (VLBW) infants and to compare modes of delivery in infants who received DCC.

Study Design: In a retrospective study, 888 VLBW infants (≤1,500 g) who survived to discharge and received immediate cord clamping (ICC) were compared with infants who received DCC. Infants who received DCC and born via Cesarean section (C-section) were compared with those born via vaginal birth.

Synthesis, microwave-assisted polymerization, and polymer properties of fluorinated 2-phenyl-2-oxazolines: a systematic study.

We present a detailed systematic study of the synthesis and ability of fluorinated 2-phenyl-2-oxazolines to undergo polymerization. The synthesis of these compounds is based on a two-step procedure that gives the desired 2-oxazolines in moderate-to-good yields. All the compounds were fully characterized by IR and NMR ((1)H, (13)C, and (19)F) spectroscopy, mass spectrometry, and elemental analysis.
