This study aimed to evaluate the effect of artificial oocyte activation (AOA) by calcium ionophore after intracytoplasmic morphologically selected sperm injection (IMSI) on fertilization, cleavage rate and embryo quality. A total 194 oocytes from 21 cycles women with a history low fertilization accompanying teratozoospermia were enrolled over 3-month period. Mature each patient randomly allocated into two groups IMSI. In group, half patients' (n = 97) exposed AOA, in control group 97), AOA...

To evaluate whether uterine artery (UtA) Doppler velocimetry during peak contraction is a useful marker for the prediction of preterm delivery.In this prospective cohort study, 172 patients admitted with (24-35 weeks' gestation) contractions were evaluated by UtA and common obstetric measurements including cervical length. For velocimetry, flow-velocity waveforms (determined visually on tocodynamometry) recorded three consecutive heart cycles, mean pulsatility index (UtA-PI) was...

Homo neanderthalensis is the closest relative to sapiens in tree of human evolution. It estimated that Neanderthals became extinct around 30 thousand years ago. Several hypotheses have been put forward explain this extinction. Larger brains hence larger heads were favoured by evolution among Hominids for over two million but stopped being an advantage due trade-offs between bipedal walking, and birth. Our hypothesis states H. as a result their head circumference, compared with sapiens,...

<title>Abstract</title> The Neanderthal extinction is a pivotal yet unresolved event in human evolutionary history. Prevailing theories have attributed their disappearance to environmental pressures and competition with Homo sapiens, but these not fully accounted for the longevity of presence across diverse challenging landscapes. According our hypothesis, birth complications caused by skull broad shoulders, which could no longer pass through pelvic bone, changed its shape onset bipedalism,...
