Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...

Background: Expansion of the use of magnetic fields in metals, mining, transport, research, and medicine industries has led to a discussion about the effects of magnetic fields and whether their strength is negligible. The aim of this study was to investigate the effects of magnetic field on the viability and proliferation rate of HeLa cells. Materials and methods: We studied the effects of ma...

Cytotoxic cancer chemotherapy drugs are believed to gain selectivity by targeting cells that proliferate rapidly. However, the proliferation rate is low in many chemosensitive human cancers, and it is not clear how a drug that only kills dividing cells could promote tumor regression. Four potential solutions to this "proliferation rate paradox" are discussed for the microtubule-stabilizing drug...

ucb-1 (pistacia atlantica × p. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. this rootstock is very new in iran and recently, it has been used commercially in some plantations due to its high growth. propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (stn) and a low proliferation rate. there...

Introduction: Now days, several studies have indicated the central nervous system has capacity for endogenous repair. But, the proliferation of endogenous neural stem cells (NSCs) is insufficient for treatment of neurodegenerative diseases. So, it sound that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The Acca sellowiana (Feijoa) extract as herbal extract is ...

Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...
