In medical clinical studies, various tests usually relate to the sample size.This paper proposes several methods to calculate sample Pens and Pencils sizes for a common test of relative risk ratios in stratified bilateral data.Under the prespecified significant level and power, we derive some explicit formulae and an algorithm of the sample size.Th
Ceramide transfer protein (CERT) transfers ceramide from the endoplasmic reticulum (ER) to the Golgi complex.Its deficiency in mouse leads to embryonic death at E11.5.CERT deficient embryos die from cardiac failure due to defective organogenesis, but not due to ceramide induced apoptotic or necrotic cell death.In the current study we examined the e
Aim: The present study aimed to evaluate and compare the efficacy and safety of oral bromelain, a natural enzyme complex with oral diclofenac sodium in managing pain and swelling after mandibular third molar surgery.Materials and methods: A total of 40 patients were randomly divided into two groups, the bromelain group (n = 20) and the diclofenac s
Abstract Background The transition to a parasitic lifestyle entails comprehensive changes to the selective regime.In parasites, genes encoding for traits that facilitate host detection, exploitation and transmission should be under selection.Slavemaking ants are social parasites that exploit the altruistic behaviour of their hosts by stealing heter
