OBJECTIVE To detect the serum levels of folate and B12 in both preclamptic and normotensive pregnant women and to determine whether there is any relation between these levels with the uterine and umbilical artery Doppler indices as well as the pregnancy outcome. MATERIAL AND METHODS This case controlled study comprised 79 pregnant patients with preeclampsia and 113 healthy, normotensive pregn...

The concept of geometric-arithmetic indices was introduced in the chemical graph theory. These indices are defined by the following general formula:     ( ) 2 ( ) uv E G u v u v Q Q Q Q GA G , where Qu is some quantity that in a unique manner can be associated with the vertex u of graph G. In this paper the exact formula for two types of geometric-arithmetic index of Vphenylenic nanotube ar...

Abstract Land reclamation significantly impacts the transformation and availability of phosphorus (P) in soils. P‐solubilizing microorganisms (PSMs) play key roles activating soil P. However, responses PSMs to buildup P under land relationship between different fractions have not been clearly clarified. Here, an investigation was carried out containing three treatments: (i) vegetable field (VF)...

An arborescence graph is a directed in which, for vertex u called the root, and any other v, there exactly one path from to v. The pathos of an Ar defined as collection minimum number arc disjoint open paths whose union Ar. In [6], Ar, total digraph Q = DP T(Ar)has set V (Q) (Ar) ∪ A(Ar) P(Ar), where set, P(Ar) A(Q) consists following arcs: ab such that a, b ∈ head coincides with tail b; uv u, ...

BACKGROUND In this study, we aimed to investigate the ability of transvaginal Doppler ultrasonography in predicting in vitro fertilization (IVF) outcome in women undergoing this procedure. MATERIALS AND METHODS In this prospective observational study, 65 infertile women underwent IVF procedure in Isfahan, during 2013-2014, were studied. The pulsatility index (PI), resistive index (RI) and pea...
