in order to optimize the micropropagation of qare-qat (vaccinium arctostaphylus j.j.sm), samples were collected from two regions of iran (asalem and kelardasht). anderson (an) media containing different concentrations of zeatin (0, 0.5, 1, 2 and 4 mg l-1) and different levels of ph (4.5, 5 and 5.5) were compared. the in vitro shoots were transferred on an media supplemented with zeatin (1 and 2...

background: endometriosis is the presence of endometrial glandular and stromal cells outside of the uterine cavity. our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3d) fibrin matrix could mimic the early stages of endometriosis with invasion gland and stroma formation and sprouting of new vessels. objective: the objective of the present study ...

the use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (ohss) and potential cancer risk. this is also true in high risk women such as those polycystic with ovary (pco) and polycystic ovarian syndrome (pcos). in vitro maturation (ivm) of oocytes was primarily developed to make ivf safe for women with pco and at high risk of o...

background: conventional ivf and icsi are two common techniques to achieve fertilization. ivf has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. the use of icsi has been expanded in severe male factor and fertilization failure after ivf cycle. in spite of the widespread use of icsi in patients with non-male factor infertility, ...

conclusions the overall results indicated that bacteriophages isolated from sewage exhibited excellent lytic activity against mrsa strains. in conclusion, bacteriophages can be further characterized and appear to be a promising candidate for phage therapy against mrsa in the future. results the phages exhibited good lytic activity against mrsa when tested in-vitro, and the highest activity was ...

the nutritive value of pistachio epicarp (pe) was evaluated by in situ and in vitro techniques. chemical analysis indicated that pe was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). total phenols, total tannins, condensed tannins and hydrolysable tannins contents in pe were 8.29%, 4.48%, 0.49% and 3.79%, respectively. ruminal dry matter and crude protein degradatio...
