microspore culture was applied to induce embryogenesis in roses (rosa hybrida) cv. hav1. important factors affecting viability of isolated microspores and formation of multi-cellular structures including isolation media (nln, ab, b) and induction media were studied. the most responsive developmental stage of microspores (late unicellular) was determined using dapi staining. the least infection ...

abstract background and objective: it has been shown that oxidative stress increases in diabetes and it has an important role in its development and subsequent complications. thus, the aim of this study was to investigate the effect of acute resistance exercise on oxidative stress in skeletal muscle and cardiac tissues of streptozotocin-induced diabetic rats. materials and methods: twenty male ...

background and aim: post-traumatic stress disorder is one of the anxiety disorders which occur in postpartum period. the prevalence of ptsd – induced by preeclampsia has been already reported as 28%, however no study was found to compare ptsd in primiparous and multiparous women. this study was therefore conducted to compare ptsd in primiparous and multiparous women. methods: this comparative d...

But one of the advantages of the new technique, as much of the media pointed out, is the ability to discriminate between afflicted males and, indeed, carrier and normal females. PGH can identify the 50 per cent of male embryos that will be unaffected, said Allison Lashwood, a consultant nurse at Guy's and St Thomas' Hospital in London.

abstract background: childhood leukemia, the most common type of cancer in children and teens, is a cancer of the white blood cells. as antioxidants can promote immune system against all types of cancer, the aim of this study was to explore the metabolic regulation and anti-oxidative effect of sesquiterpen-rich extract of ferula asafoetida (fa) on children with leukemia. materials and methods: ...

background and objective: in this research, the effect of chronic dietary soybean aqueous extract on aortic reactivity of streptozotocin (stz)-diabetic rats was investigated. materials and methods: stz-diabetic rats were treated with soybean aqueous extract for two months after diabetes induction. contractile reactivity to kcl and phenylephrine (pe) and relaxation response to acetylcholine (ach...
