Tomato (Solanum lycopersicum) is one of the most important crops and a known host of broomrapes. The species of genus Orobanche are biotic stress factors restricting plant growth and crop production. Some natural compounds and chemicals affect this biological relationship. Therefore, in the present study, the effect of gallic acid and kiwi fruit extract on the biological relationship between broomrape and tomato plant was investigated. To this end, first, the symbiotic effect of the broomrape species, Orobanche aegytica, on growth parameters of tomato plant and the amount of soluble sugar and photosynthetic pigments were evaluated. Then, the effect of concentrations of gallic acid and kiwi fruit extract at different levels on this biological relationship was investigated by measuring the growth parameters of tomato and broomrape, photosynthetic pigments and the amount of soluble sugar in tomatoes. The results demonstrated that the broomrapes reduced the fresh weight and dry weight of the stem, leaves and roots of tomato, diminished the leaf area of the host plant, and decreased the amount of photosynthetic pigments and its soluble sugar content. Gallic acid treatment and kiwi fruit extract lessened the growth parameters of the broomrape species and its overall growth, in addition to increasing the growth of tomato plants. This process could be associated with the constraint of the biological relationship between the parasite and the host, as the soluble sugar content as well as the amount of the photosynthetic pigments of tomato plants were increased and the tomato plants remained highly resistant.

Pollen respiratory allergies have been increasing in prevalence over the last two decades, partly as the result of the impact of climate change. For many allergenic trees, grass and weed species, increased pollen production and prolonged pollination period result in long-term increased abundance of pollen allergens in the atmosphere; earlier shifts of airborne pollen grains and prolonged exposure to respiratory allergens with important health effects on allergic individuals. The aim of this review paper was to investigate the impact of climate change and meteorological factors on pollen season indicators with a special focus on the main allergenic taxa worldwide. Main variables influencing flowering phenology such as location, climatic and meteorological parameters were identified, discussed and substantiated by published literature. Temperature, solar radiation, humidity, rainfall, wind speed and direction were identified among the most important meteorological parameters affecting the fluctuations of annual concentrations of allergenic airborne pollen grains. Although notable variations were observed according to allergenic species and studied geographical areas, temperature appeared to be the most important climatic parameter affecting flowering phenology and pollen season indicators, especially in tree species. Rising carbon dioxide levels also result in increased plant biomass, increased flowering intensity and pollen production in several tree, grass and weed allergenic species. In the light of this review, there is a growing body of evidence supporting the effect of climate change on the flowering phenology and pollen season indicators of a substantial number of allergenic ornamental and invasive plant species.

Cisplatin, as a chemotherapy drug, causes serious side effects in the advanced stages of the cancer. Recently, Artemisia has been considered for its bioactive compounds, anti-proliferative and anti-inflammatory effects. The aim of this study was to evaluate the anti-cancer and anti-metastatic effects of the methanolic extract of aerial organs of Artemisia and cisplatin, either alone or in combination, in human ovarian cancer cell line A2780. The viability of A2780 cells after treatment with Artemisia extract, cisplatin and their combination was evaluated by MTT assay and the alterations in the morphology of the cell nuclei were examined by DAPI staining. The induction of apoptosis was assessed by Annexin V test, cell migration and changes in expression levels of apoptotic genes (Bax and P53) and metastasis (MMP2 and MMP9) using real-time PCR. MTT test data showed that Artemisia extract, cisplatin and their combination decreased the viability of ovarian cancer cells. DAPI and Annexin V indicated the DNA fragmentation and increased percentage of cellular apoptosis in comparison with the control group. The migration and real-time PCR data showed a decline in thr cell invasion and expression of genes involved in metastasis (MMP2 and MMP9) in cancer cells while the expression of apoptotic genes (Bax and P53) was increased in the treated groups. The results of this study showed that while both Artemisia extract and cisplatin posses anti-proliferative effect, apoptotic and suitable anti-metastatic effects on their own in A2780 cell line, their combination have synergic effects and posses those desired properties in lower concentration of cisplatin, which can reduce the side effects of cisplatin in cancer treatment.

Biological anthropology, as a branch of anthropology, studies the evidence of evolution, diversity, biological and cultural adaptation that has made us the modern humans we are. The centrality of "human" evolution in anthropology has led to the formation of interdisciplinary, methodological, and conceptual links with other sciences. Apart from the lack of access to topics such as primatology in Iran due to the lack of cultural, geographical, and research context, the study of genetic and physical characteristics of contemporary ethno-cultural and demographic groups, biological evolution, and environmental adaptation have constituted the majority of studies in this field. The lack of sufficient studies on the approaches and goals of biological anthropology and the failure to address the capacities of this science in recent years have led to its conceptual framework being less well known in Iran. Therefore, the present study, while showing the importance of interdisciplinary scientific communities, has attempted to assessment the approaches of biological anthropology in Iran by reviewing 92 articles from related research whose research was conducted in Iran. The selected articles claimed to be conducting anthropological research in terms of title, subject, method, and approach. The present study
