it is estimated that annually 10 million people are affected by traumatic brain injury and it is one of the major causes of death and disability in accidents. studies have shown the potential therapeutic value of neural stem cell therapies. also, neural stem cell motility and migration to the site of injury has a great regeneration value of the damaged tissues. extracellular and intracellular f...

BACKGROUND: A major issue in many gene expressionstudies utilizing small amount of biological materials is thelimited quantity of RNApurified from clinical samples, which isoften used for RT-PCR or standard Northern blot analysis.OBJECTIVES: The SMART cDNA synthesis method and subsequentSMART-cDNA-PCR technique was used to analyse 3genes in macroschizonts of Theileria annulata in small lymphnod...

macrophage colony stimulating factor (m-csf) has previously been shown to affect the differentiation of cells of the mono-nuclear phagocytic line. more recent studies indicate that m-csf may have a role in pregnancy. in the present study, the expression of m-csf in the human placenta was demonstrated. placental mrna was isolated and used as template for synthesis of complementary dna (cdna). th...

Quantitative real-time PCR (QPCR) was used to quantify the genome of Solenopsis invicta virus-2 (SINV-2) from infected individual ants of S. invicta. Strand-specific cDNA synthesis oligonucleotide primers and RNase digestion after cDNA synthesis allowed quantification of plus (genomic) and minus (replicative) strands of the SINV-2 genome. Both strands were detected in adult workers and larval f...

mouse embryonic stem cells (es) are pluripotent cell lines derived from the inner cell mass of the blastocyst. their properties include self renewal and capacity to differentiate into different cell types. neural differentiation of es cells has been achieved by several different protocols such as treating with retinoic acid and serum decreasing in culture media. the ppars (peroxisome proliferat...

Background and objectives:  Gastric cancer is currently known as one of the most important causes of cancer-driven death all over the world. In patients with gastric cancer, a significant proportion of death occurs due to metastasis. On the other hand, down modulated E-cadherin level has been reported as an important contributor to tumor cell invasion and metastasis. In this re...

Obtaining full-length cDNA is important for many molecular biology methods like cDNA library construction or RACE-PCR (rapid amplification of cDNA ends). We have found that the inclusion of betaine alone and in combination with trehalose in reverse transcription results in longer cDNA synthesis products. As shown on the 14-kb long clarithrin mRNA with real-time PCR, a combination of 2 M betaine...
