Premenstrual syndrome (PMS) is a regularly recurring cluster of mood and somatic symptoms, occurring during the luteal phase of the menstrual cycle. According to the American College of Obstetricians and Gynecologists, 20–40% of women have some premenstrual symptoms.1 In ~5% of women of reproductive age, the symptoms are severe enough to seriously disrupt their lives and relationships,2 thereby...
Suffix trees are the most frequently used data structures in algorithms on words. In this paper, we consider the depth of a compact suffix tree, also known as the PAT tree, under some simple probabilistic assumptions. For a biased memoryless source, we prove that the limiting distribution for the depth in a PAT tree is the same as the limiting distribution for the depth in a PATRICIA trie, even...
Different biological methods are gaining recognition for the production of silver nanoparticles (Ag-NPs) due to their multiple applications. One of the most important applications of Ag-NPs is their use as an anti-bacterial agent. The use of plants in the synthesis of nanoparticles emerges as a cost effective and eco-friendly approach. In this study the biosynthesis of silver nanoparticles usin...
Clinical trials have demonstrated that serotonin reuptake inhibitors (SRIs) and the extract of Vitex agnus castus are effective for the treatment of premenstrual dysphoric disorder (PMDD). However, to the best of our knowledge, there has been no study comparing the efficacy of the SRIs with Vitex agnus castus (AC) extract. Therefore, the aim of the present study was to compare the efficacy of f...
The title compound, C(42)H(63)O(4)P, was isolated from the leaves of Vitex negundo. Two of the tert-butyl groups are disordered over two orientations with occupancy ratios of 0.57 (1):0.43 (1) and 0.67 (1):0.33 (1). Several intra-molecular C-H⋯O inter-actions are observed in the mol-ecular structure.
Effect of solvent residues of Vitex negundo L. and Cassia fistula L. leaves (0.5 and 1%) was studied on egg laying and adult emergence of Callosobruchus maculatus Fab. and on percentage of larval parasitism by Dinarmus vagabundus (Timberlake). Cowpea seeds treated with methanol and aqueous extract of Vitex, at these concentrations (0.5 and 1%), significantly reduced the number of eggs and emerg...
North Bangkok. ** Department of Chemistry, Faculty of Science, Ramkhamhaeng University. Abstract A new ecdysteroid, P5, has been isolated from the stem bark of aged trees (with flower) of vitex canescens. 20-Hydroxyecdysone, makisterone A, 24-epi-makisterone A, and canescensterone have also been isolated from both young trees (without flower) and aged trees (with flower) of vitex canescens. The...
Two new labdane-type diterpenoids vitetrifolin H (1) and vitetrifolin I (2), and one new monoterpenoid vitexoid (3), were isolated from the fruits of Vitex trifolia L., together with seven known diterpenoids. Structures of all compounds were elucidated by extensive spectroscopic methods. All these compounds exhibited inhibition of Hela cell proliferation, with IC50 values in the range of 4-28 m...
Economic and environmental logging is important for sustainable wood production in the Caspian forests, north of Iran. Predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. The aim of this study was evaluation of directional felling and finding factors effective on felling error. Totally 135 trees were selected randomly for di...
Evaluation of different sampling method to study of tree density (tree/hectare) in the Zagros forest
For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree density in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran was selected. 40 s...
