conclusions this study showed that aloe vera has antibacterial effects against e. coli, and can result in structural and physiological changes in this bacterium. objectives the aim of this research was to evaluate the effects of an aloe vera extract on the morphological and physiological properties of escherichia coli. patients and methods a clinical isolate of e. coli was obtained from a patie...

introduction preterm infants are exposed to irregular light for several weeks or months in the neonatal intensive-care unit (nicu). this lack of maternal entrainment, the exposure to irregular extrauterine lighting and care in the nursery may contribute to the disturbances in body temperature, sleep and physiological changes that are commonly experienced by preterm infants. materials and method...

the variation in climatic variables like temperature, humidity and radiations were recognized as the potential hazards in the growth and production of all domestic livestock species. thermal environment is a major factor that can negatively affect both production and reproduction in dairy animals, especially in animals of high genetic merit. among the stressors, heat stress has been of major co...

Physiological changes occur in pregnancy to nurture the developing foetus and prepare the mother for labour and delivery. Some of these changes influence normal biochemical values while others may mimic symptoms of medical disease. It is important to differentiate between normal physiological changes and disease pathology. This review highlights the important changes that take place during norm...
