Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...

ucb-1 (pistacia atlantica × p. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. this rootstock is very new in iran and recently, it has been used commercially in some plantations due to its high growth. propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (stn) and a low proliferation rate. there...

nitrite intoxication occurs frequently in ruminants and equines. the most common treatment of this disorder is administration of 1% methylene blue, although the use of some antioxidant agents e.g. vitamins and complementary treatment may also be useful. the aim of this study was to evaluate the in vitro antioxidative effects of some vitamins on methemoglobinemia induced by sodium nitrite. for t...

artemisinin and its derivatives are very important new class of antimalarial drugs. one of the most important artemisinin derivatives is artemether. the antiparasitic activity of artemether as a derivative of artemisinin is related to endoperoxide bridge in its structure. the aim of this study was the evaluation of antileishmanial effect of artemether, with more focus on its apoptotic effect. i...

the condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new schiff bases. the structure of schiff bases were confirmed by 1h nmr, 13c nmr, ir and mass spectro...

the main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. embryo transfer (et) is the last step of critically important procedure of in vitro fertilization (ivf) and probably the least successful step in assisted reproductive technology (art) treatment cascade; though simple in most of the cases, it may pose to be the most diff...

background: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...

background: ovarian pregnancy constitutes 0.15-3% of all ectopic pregnancies. the incidence of ectopic pregnancy is on the rise owing to evolution in assisted reproductive techniques (art). the incidence reported following in vitro fertilization (ivf) or embryo transfer (et) is 0.27% per clinical pregnancy. case: we present a case of a 13-weeks ovarian pregnancy following ivf-et and through a r...
