BACKGROUND New lymphatic growth may contribute to tumor metastasis. Activation of vascular endothelial growth factor receptor 3 (VEGFR-3) by its ligands VEGF-C and -D is necessary for embryonic and tumor lymphangiogenesis. However, the exact role of VEGFR-3 signaling in adult lymphangiogenesis and in lymphatic vessel survival and regeneration is unclear. METHODS A novel rat monoclonal antibod...

The optimum condition for the protoplast formation and regeneration of S(yeptomyces Laurentii ATCC 31255 was studied. The effective formation and regeneration of protoplasts were obtained by using the mycelia grown to the stationary phase in the presence of 0.4% glycine, and by treatment with 1 mg/ml of lysozyme in PWP buffer. When plasmids, pMCP5 and its derivative pYK3 (smaller in size) havin...

Loss of posterior segments from immature Nereis is followed by the associated processes of wound healing and segment regeneration. In the absence of a hormone secreted by the brain, wound healing alone ensues. However, proliferation of segments can be initiated by intracoelomic implantation of a living brain (removed from a donor) during the course of wound healing or subsequent to its completi...

Aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. This species has been endangered at northern forests of Iran; therefore micropropagation of adult trees by bud culture may help to reforestation. The best sterilizing treatment was the buds washing with HgCl2% 0.1 solution for 7 ...

The spinal cord injury (SCI) refers to a condition that the damage to the spinal cord causes neurologic dysfunction. In the case of neurologic dysfunction owing to SCI, its recovery is desperate, and the pathological condition appears as the incompetence of the body. Originally, neural axons can expand even after injury and produce a recovery of the neuronal network [1]. However, the SCI leads ...

The desiccant material is a material which has ability to remove moisture from air. According to the physical and chemical properties, there are two types of desiccant material namely solid desiccant material and liquid desiccant material. In this experimental study, solid desiccant material is used. Solid desiccant material adsorbs moisture from air due to water vapour pressure difference. Som...
