background: ovarian tissue transplantation is emerging technologies for fertility preservation. in addition, in vitro maturation (ivm) of oocytes retrieved from ovarian tissues may overcome the fertility defects in certain cases. objective: the aim was to evaluate the best site for ovarian tissue transplantation in mice. also, feasibility of ivm of oocytes retrieved from auto grafted ovarian ti...

The aims of the present study were to assess the effects of cysteamine as an anti-oxidant on the rate of in vitro maturation (IVM) of buffalo oocytes (experiment 1), and their viability and nuclear status following vitrification (experiment 2). Immature oocytes with compact cumulus cells obtained from the ovaries of slaughtered animals were harvested and then cultured in the maturation medium w...

background:   objective: in this study, we supplemented a chemically defined medium with different combinations of selenium, calcium and calcium ionophore concentrations to obtain the best rate of human oocytes maturation, survival, and fertilization.   materials and methods: as an experimental study, three combinations of [selenium (5 μg/ml), calcium (5 μg/ml) and calcium ionophore (1 μg/ml)],...

Aims: Trypanosomiasis is an important protozoan disease that affects domestic and wild animals as well man. It caused by the tsetse fly-transmitted extracellular hemo-flagellates belong to genus, Trypanosoma. In East Southern Africa, Human African (HAT) Trypanosoma brucei rhodesiense while in West Central it T. b. gambiense. Animal trypanosomiasis on other hand brucei, vivax, congolense. sub-Sa...

The success of endodontic treatment not only lies in meticulous cleaning, perfect shaping and precise filling of canels, it also embodies vital importance on familiarity of unusual root canal patterns. This article presents a case report of a maxillary first molar that had two separate palatal roots with distinct canals and also an invitro assessment of an extracted tooth which had a a similar ...

The study was designed to evaluate the anti-inflammatory and antioxidant activity of a poly herbal formulation-Chyavana drink. The inflammation was induced in albino rats by carrageenan. The formulation was effective when compared with a known anti-inflammatory drug. The antioxidant activity was studied by invitro methods. The DPPH radical scavenging activity was found to be showing higher perc...

Alcoholic extracts of the rhizomes of Alpinia galanga, Andrographis paniculata, bark of Cinnamomum zeylanicum, rind of Citrus decumana, Desmodium triflorum, seeds of Hydnocarpus wightiana, rhizomes of Kaempfaria galanga, Lippia nodiflora, tender leaves of Morinda citrifolia, rhizomes of Pollia serzogonian, Tephrosia purpuria and rhizomes of Zingiber zerumbeth showed good in vitro anthelmintic a...

Invitro antioxidant activity and Molecular modeling studies of nine chromone derivatives optimize their inhibitory activity against Poly [ADP correlated to different molecular properties. The AM1and PM3 semiempirical methods are used to estimate vertical ioniz tion potentials (IPv’s), electron affinity (EA tion coefficient (LogP), hydration energ regression analysis are proposed. The leave fina...

Background Human immunodeficiency virus (HIV) infection causes acquired immune deficiency syndrome (AIDS) and is a global public health issue. Anti-HIV therapy involving chemical drugs has improved the life quality of HIV/ AIDS patients. However, emergence of HIV drug resistance, side effects and the necessity for long-term antiHIV treatment are the main reasons for failure of antiHIV therapy. ...

Background: The buffalo (Bubalus bubalis) is the animal with special production characteristics in producing milk and meat has a critical role in rural industry in Iran. The most problem of this specie is its low reproductive output. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on maturation rate of Buffalo oocyte.Materials and Methods: Ovaries were colle...
