Cellular strategies remain a crucial component in bone tissue engineering （BTE）. So far, the outcome of cell-based strategies from initial clinical trials is far behind compared to animal studies, which is suggested to be related to insufficient nutrient and oxygen supply inside the Ussue-engineered constructs. Cocultures, by introducing angiogenic cells into osteogenic cell cultures, might provide a solution for improving vascularization and hence increasing bone formation for cell-based constructs. So far, pre-clinical studies demonstrated that cocultures enhance vascularization and bone formation compared to monocultures. However, there has been no report on the application of cocultures in clinics. Therefore, this mini-review aims to provide an overview regarding （i） critical parameters in cocultures and the outcomes of cocultures compared to monocultures in the currently available pre-clinical studies using human mesenchymal stem cells implanted in orthotopic animal models; and （ii） the usage of monocultures in clinical application in BTE.

Objective： The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function. Methods： The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers. Results： Currently, various organizations are involved in prevention, management and rehabilitation of injuries, but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement, hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure （regarding staff, maintenance, financial resources）, it is not yet established in our system of trauma care. Conclusions： It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.

The role played by Paleoproterozoic cratons in southern South America from the Mesopro- terozoic to the Early Cambrian is reconsidered here. This period involved protracted continental amal- gamation that led to formation of the supercontinent Rodinia, followed by Neoproterozoic continental break-up, with the consequent opening of Clymene and Iapetus oceans, and finally continental re-assembly as Gondwana through complex oblique collisions in the Late Neoproterozoic to Early Cambrian. The evidence for this is based mainly on a combination of precise U-Pb SHRMP dating and radiogenic isotope data for igneous and metamorphic rocks from a large area extending from the Rio de la Plata craton in the east to the Argentine Precordillera in the west and as far north as Arequipa in Peru. Our interpretation of the paleogeographical and geodynamic evolution invokes a hypothetical Paleoproterozoic block （MARA） embracing basement ultimately older than 1.7 Ga in the Western Sierras Pampeanas （Argentina）, the Arequipa block （Peru）, the Rio Apa block （Brazil）, and probably also the Paraguaia block （Bolivia）.

Rice blast disease, caused by Magnaporthe oryzae, threatens global food security. The rice blast pathosystem is a longstanding model system for understanding plant-microbe interactions. In order to elucidate the coevolution of the host and pathogen, and provide the appropriate methods for preventing or controlling rice blast disease, researchers have focused on the evolution of virulence factors and resistance genes. Thus far, more than 30 rice blast resistance（R） genes and 12 avirulence（Avr） genes have been cloned. This review summarizes the cloned rice blast R genes, cloned Avr genes of M. oryzae and the interaction between them. This discussion also considers some of the major unanswered questions concerning this pathosystem and the opportunities for future investigations.
