Background and objectives: Phlomis bruguieri Desf. (Lamiaceae) is a perennial herbaceous plant distributed in Iran, Turkey and Iraq. Despite medicinal potentials of this species, the current knowledge on its phytochemical constituents is limited. The aim of the present study was to investigate the phytochemical constituents of the essential oil and various extracts of ...

For any simple connected graph $G=(V,E)$, a defensive alliance is a subset $S$ of $V$ satisfying the condition that every vertex $vin S$ has at most one more neighbour in $V-S$ than it has in $S$. The minimum cardinality of any defensive alliance in $G$ is called the alliance number of $G$, denoted $a(G)$. In this paper, we introduce a new type of alliance number called $k$-strong alliance numb...

The paper deals with the best unbiased estimators of the blocked compound symmetric covariance structure for m−variate observations over u sites under the assumption of multivariate normality. The free-coordinate approach is used to prove that the quadratic estimation of covariance parameters is equivalent to linear estimation with a properly defined inner product in the space of symmetric matr...

A k-hypertournament is a complete k-hypergraph with each k-edge endowed with an orientation, that is, a linear arrangement of the vertices contained in the edge. In a k-hypertournament, the score si (losing score ri) of a vertex vi is the number of arcs containing vi in which vi is not the last element (in which vi is the last element). The total score of vi is defined as ti = si − ri. In this ...

Background and Aims: Tranexamic acid has been used to decrease blood loss volumes and the subsequent need for blood transfusion in the orthopedic, spinal and cardiac surgeries. Methods: In this prospective controlled randomized clinical trial study, 24 candidates for orthognathic surgeries received tranexamic acid (20 mg/kg) intravenously just before the surge...

Objective(s): Populus species have various pharmacological properties, including antioxidant activity. In this study, the effects of Populus tomentiglandulosa extract (PTE) on histopathology and antioxidant enzymes in the rat liver and kidney were examined.  Materials and Methods: Sprague-Dawley rats were assigned to three groups; (1) no...

Dahlia pinnata is a species of the genus dahlia, belonging to the family Asteraceae. The present study reported the use of dahlia pinnata flower extract as an acid base indicator in different types of acid base titrations. The equivalence point obtained by the flower extract coincided with the equivalence point obtained by standard indicators. The results obtained by the flower extract matched ...

Background and objectives: Because of the importance of breast cancer as a first cause of morbidity and mortality among females, also the limitation of chemotherapy and based on literature of the use of herbal medicines against cancer, the current study was aimed to determine the efficacy of Berbers vulgaris fruit ethanol extract against MCF-7 breast cancer cell line. ...
