BACKGROUND Few studies are grounded in a developmental framework to study proactive and reactive aggression. Furthermore, although distinctive correlates, predictors and outcomes have been highlighted, proactive and reactive aggression are substantially correlated. To our knowledge, no empirical study has examined the communality of genetic and environmental underpinning of the development of b...
Governance for complex problem solving has been increasingly discussed in environmental sustainability research. Above all, researchers continuously observe that sustainability problems are complex or “wicked”, and suggest participatory models to address these problems in practice. In order to add to this debate, this study suggests a more differentiated theoretical approach to define governanc...
mucinous carcinoma of the breast is a well-differentiated type of adenocarcinoma accounting for 2-5% of all breast cancers. pure mucinous carcinoma of the breast has a favorable prognosis, usually seen in post-menopausal women. neuroendocrine differentiation has been described in both in-situ and infiltrating breast cancers .mucinous carcinomas of the breast appear to have the greatest associat...
ginger (zingiber officinale rosc.) is a herbaceous, rhizomatous, perennial, which its rhizomes are used as an important spices and medicine all over the world. the aromatic principles include zingiberine, while the pungent principles are known as gingeroles. callus culture of the plants can produce the same compounds exist on their parent plants. the aim of this work was to evaluate the effect ...
objective(s):sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. this study was performed to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rbmmsc) into osteogenic lineage. materials and methods: isolated rbmmsc were grown in dmem supplemented with 10% fbs. the cells were exposed to different concen...
Osteosarcoma is the most frequent, nonhematopoietic, primary malignant tumor of bone. Histopathologically, osteosarcoma is characterized by complex mixtures of different cell types with bone formation. The role of environmental factors in the formation of such a complicated tissue structure as osteosarcoma remains to be elucidated. Here, a newly established murine osteosarcoma model was used to...
inter simple sequence repeat (issr) analysis was performed to evaluate genetic diversity and genetic structure of six capoeta trutta populations from two main watersheds in the kurdistan province. fish samples were caught from the choman, shooei, garmab rivers in the choman watershed and from the gheshlagh, gavarood, sirvan rivers in the sirvan watershed. from six used dinucleotide primers, thr...
in order to identify the sex marker in mahisefied, rutilus frisii kutum, samples from 5 male and 5 female fish were collected from the south caspian sea. polymerase chain reaction random amplified polymorphic dna (pcr-rapd) was performed using 124 primer sets. all bands were numbered using 1 and 0 scores corresponding to the presence or absence of bands, respectively and data were analyzed usin...
Over the last two decades, the incidence of obesity and associated metabolic syndrome diseases has risen dramatically, becoming a global health crisis. Increased caloric intake and decreased physical activity are believed to represent the root causes of this dramatic rise. However, recent findings highlight the possible involvement of environmental obesogens, xenobiotic chemicals that can disru...
BACKGROUND AND AIMS Solving relationships of recently diverged taxa, poses a challenge due to shared polymorphism and weak reproductive barriers. Multiple lines of evidence are needed to identify independently evolving lineages. This is especially true of long-lived species with large effective population sizes, and slow rates of lineage sorting. North American pines are an interesting group to...
