Chaharmahal and Bakhtiari province is a most important endemism states of flora of Iran with a considerable plant species diversity in the country. In the present study the cytotoxic activity of 13 plant species grown in Chaharmahal and Bakhtiari have been evaluated on prostate (PC-3), breast (MCF-7), liver (HepG2), ovary (CHO) and melanoma (B16-F10) cancer cell lines. The cytotoxicity and apop...

A fundamental challenge to our understanding of biodiversity is to explain why some groups of species diversify, whereas others do not. On islands, the gradual evolution of a new species from a founder event has been called 'anagenetic speciation'. This process does not lead to rapid and extensive speciation within lineages and has received little attention. Based on a survey of the endemic bry...

All Qinghai-Tibetan Plateau (QTP) endemic species are assumed to have originated recently, although very rare species most likely diverged early. These ancient species provide an excellent model to examine the origin and evolution of QTP endemic plants in response to the QTP uplifts and the climate changes that followed in this high altitude region. In this study, we examined these hypotheses b...

Endemic medicinal plants that grow at altitudes in northern Chile have been traditionally used for therapeutic applications by Aymara doctors. Several studies analyzed the biological properties of these purposes. The aim was to characterize molecular and biochemical levels bacteria live rhizosphere roots from endemic between 3681–5104 m.a.s.l. province Parinacota. Thirty-nine were isolated nine...

Gypsophila bermejoi G. López is an allopolyploid species derived from the parental G. struthium L. subsp. struthium and G. tomentosa L. All these plants are gypsophytes endemic to the Iberian Peninsula of particular ecological, evolutionary and biochemical interest. In this study, we present evidence of a possible repression on the process of G. bermejoi speciation by climatic factors. We model...

BACKGROUND Goiter rates and iodine deficiency usually show marked improvement in efficacy studies of mandatory iodization of salt, but little is known about the short-term effectiveness of mandatory iodization. OBJECTIVE The aim of the study was to evaluate, after 1 y, the effectiveness of mandatory iodization of salt at an iodine concentration higher than that occurring under optional iodiza...

OBJECTIVES To estimate the prevalence of active trachoma (TF) in children aged one to nine years and potentially blinding trachoma (TT) in adults aged 15 years and older in six known trachoma-endemic districts in Kenya. DESIGN Community based survey. SETTING Six known trachoma endemic districts in Kenya (Samburu, Narok, West Pokot, Kajiado Baringo and Meru North). SUBJECTS A total of 6,98...

BACKGROUND In programs to control iodine deficiency disorders (IDD), sustainability is a major concern. IDD has recently recurred in countries where salt iodization programs have lapsed. OBJECTIVE The objective of the study was to describe the evolution of thyroid dysfunction after the discontinuation of salt iodization in a cohort of children in an area of severe endemic goiter. DESIGN Mor...

Plant species diversity in Jokhaneh plain and the southern slope of Nil Mt. is investigated in order to determine the flora and life forms and chorotypes of plants in this area. The studied area is located in Kohgilouyeh va Boyerahmad province, covers 22’475 hectares and its average elevation is 2’315 m above sea level. In spite of a few studies in this region, broad knowledge of the flora of t...
