background: heat stress is one of the most important consequences of occupational heat exposure worldwide. current heat stress indexes are not suitable for heat strain screening in developing countries due to their inherent and applied limitations. a new observation and subjective screening method is required that needs no instrument. in this study, a scale is developed based on the most import...

after central nervous system (cns) injuries, the regeneration process does not work out well except for remyelination process. this remyelination capacity in cns can be mentioned as a worthy example of stem/precursor cell-mediated renewal process. remyelination in cns is mediated by schwann cells which act mainly as remyelinating agents in peripheral nervous system (pns) but several studies hav...

Background and Aims: Measles remains one of the leading causes of childhood morbidity and mortality in developing countries and is still a major public health concern in developed countries. Although live attenuated vaccine is used throughout the world, out breaks of disease still occur in many countries including Iran. Methods: The present study was performed to evaluate the immune status aga...

Genomic attempts were undertaken to elucidate the plant developmental responses to heat stress, and to characterize the roles of B2 protein in mediating those responses. A wheat expressed sequence tag for B2 protein was identified which was cloned and characterized to assess its functional relevance causing plant growth and development during stress adaptation. Here, we show that wheat B2 prote...

abstract prevention of infectious diseases by immunization in children has markedly diminished the morbidity and mortality of once common contagious diseases in many countries worldwide. immunization programs have led to the global eradication of smallpox, elimination of measles and poliomyelitis in regions of the world, and substantial reduction in the morbidity and mortality attributed to dip...

Scope of the problem Acute respiratory tract infection is the leading cause of hospitalization for infants and young children in developed countries, and a major determinant of death in developing countries. In 2002, lower respiratory tract infections accounted for approximately 4 million deaths worldwide and 7% of all deaths that year [1]. Therefore, there is a huge need for new diagnostic too...

New crop cultivars will be required for a changing climate characterised by increased summer drought and heat stress in Europe. However, the uncertainty in climate predictions poses a challenge to crop scientists and breeders who have limited time and resources and must select the most appropriate traits for improvement. Modelling is a powerful tool to quantify future threats to crops and hence...

In Arabidopsis and rice, miR159-regulated GAMYB-like family transcription factors function in flower development and gibberellin (GA) signaling in cereal aleurone cells. In this study, the involvement of miR159 in the regulation of its putative target TaGAMYB and its relationship to wheat development were investigated. First, we demonstrated that cleavage of TaGAMYB1 and TaGAMYB2 was directed b...
