TL;DR: The ontogeny, anatomy and ultrastructure of the internal glands of C. langsdorffii during plant development are investigated and Lipophilic and hydrophilic compounds were histochemically detected in both canals and cavities, whereas resin was detected only in canals.

TL;DR: The prevalence of Caesarean Sections was higher over vaginal births, and high number of referred patients who underwent Emergency sections was the main reason.
Abstract: Caesarean section rates are inexorably rising which has led to the possibility of negative impact on m aternal and neonatal health. Present study was aimed to compare the factors associated with caesarean and vaginal births among pregnant women. A retrospective study was con ducted in Obstetrics and Gynaecology Department, Pu njab Institute of Medical Sciences, Jalandhar (Punjab, Iduring the period of April, 2012 to June, 201 2. Details of age group, parity, socioeconomic status, antenatal booking, mode of delivery, obstetric complications, gestational age at delivery, maternal and neonatal outcomes wer e explored. The prevalence of Caesarean Sections (6 5%) was higher over vaginal births (35%). It had higher num ber of Emergency (52.31%) over Elective (47.70%) ca esarean sections. Multiparity (55.38%; p<0.05), high socioe conomic status (18.46%), 21 to 30 yrs of age group (78.46%) and booked status (44.62%) were associated with Cae sarean Sections while primiparity (65.71%) and low socioeconomic status (22.86%) with vaginal births. The commonest reasons for Caesarean Sections were F etal Distress (30.77%) and Repeat Caesarean Sections (29.23%). Ca esarean sections rate is high. High number of referred patients who underwent Emergency sections was the main reason. Trial of vaginal birth after C aesarean Section in approximate cases and confirmation of su spected fetal distress through fetal blood acid bas e study are recommended.

TL;DR: The presence of Weinmannioxylon in Late Cretaceous sediments suggests that taxa within or stem taxa to the Cunoniaceae might have been a notable component of the forest vegetation that covered the Antarctic Peninsula during the Late Mesozoic and may represent the earliest record of this family.
