objective(s):ethnopharmacological field surveys demonstrated that many plants, such as gentiana olivieri, helichrysum graveolens, helichrysum plicatum ssp. plicatum, juniperus oxycedrus ssp. oxycedrus, juniperus  communis var. saxatilis, viscum album (ssp. album, ssp. austriacum), are used as traditional medicine for diabetes in different regions of anatolia. the present study was designed to e...

the major foible of dental ceramics is their brittle nature. therefore, the producers of these materials have focused on the “strength” issue. a method of increasing strength is ion exchange on porcelain surface which leads to formation of a compressive crust that opposing forces should overcome before developing a crack. in current study, ion exchange in two types of porcelain, ceramco ii whic...

in surrogate pregnancies genetic parents have little opportunity for early bonding with their infants either prenatally (in utero) or during the immediate postnatal period. procedures commonly used to induce lactation include both pharmacologic and nonpharmacologic methods often in combination. studies reporting induced lactation are sparse due to the rarity of augmented lactation. here we repo...

in this paper, we consider singular and degenerate parabolic equations$$u_t =(x^alpha u_x)_x +u^m (x_0,t)v^{n} (x_0,t),quadv_t =(x^beta v_x)_x +u^q (x_0,t)v^{p} (x_0,t),$$ in $(0,a)times (0,t)$, subject to nulldirichlet boundary conditions, where $m,n, p,qge 0$, $alpha, betain [0,2)$ and $x_0in (0,a)$. the optimal classification of non-simultaneous and simultaneous blow-up solutions is determin...

Background: Vitrification of oocytes is a fast-freezing technique, which may affect the quality of the human oocyte, and consequently affects the embryo development, pregnancy and birth. The aim of the current study was to investigate the consequence of in-vitro vitrification on maturation status of immature human oocytes, additionally, expression levels of stress, and apoptosis related genes. ...
