in order to study effects of application time of chevalier herbicide and integrate of illoxan with granstar on wheat and weed inahwaz, an experiment was conducted in ramin agriculture and natural resources university during 2007-2008, in split plot design by randomized complete blocks design with four replications. experimental factors was chevalier and integrate of granstar and illoxan herbici...

Stem cells can be categorized into three different types based on their respective ability to differentiate. The first type is totipotent stem cells, which can be implanted in the uterus of a living animal and subsequently give rise to a full organism. The second type of stem cell is the pluripotent stem cell, such as embryonic stem cells and iPSCs. These cells can give rise to every cell of an...

Objective(s):Transplantation quality improvement and reduction of cellular damage are important goals that are now considered by researchers. Melatonin is secreted from the pineal gland and some organs such as testes. According to beneficial effects of melatonin (such as its antioxidant and antiapoptotic properties), researchers have proposed that the use of melatonin may improve transplantatio...

Background: Hospitals may be under pressure to implement cost saving strategies regarding prosthesis choice. Thismay involve the use of components which are not the first preference of individual surgeons, or those they have littleexperience with. We aim to examine the effect of standardizing the type of femoral stem used in a single trust, anddetermine whether this is safe practice, particular...

Traumatic brain injury (TBI) is physical damage to the brain structure which has a high global rate of mortality and morbidity. TBI can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. Microglia can differentiate into M1 macrophages or M2 macrophages following the changes in biochemical properties of brain tissue. M1 sub type ...

spinal cord injury (sci) is a destructive event that often lead to permanent neurologic deficit. current clinical treatments are aimed at preventing secondary damage, promoting regeneration, and replacing destroyed spinal cord tissue, although effective treatments for sci remain limited. cell therapies for treating sci are promising therapy for replacing dead cells, neuroprotection and axon reg...

mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...
