OBJECTIVES: It is now supposed that cytokines released during the burn injuries have a great impact on the immunological and pathological responses after the burn. The main objective of this study was to investigate the expression of some pro-inflammatory genes in the wound, spleen and blood neutrophils during the healing process of burn wounds in a murine model. MATERIALS AND METHODS: The expression of ten pro-inflammatory genes were examined in wounds, spleens and blood neutrophils of mice with burn injuries treated with either silver sulfodiazine or phosphate-buffered saline (PBS) using RT-PCR at the end of the first and second weeks after injuries...

The effects of PM10 on hemodynamic parameters, lipid peroxidation, and infarct size induced by ischemia-reperfusion injury and the protective effects of vanillic acid (VA) in isolated rat heart were investigated. MATERIALS AND METHODS: Eighty male Wistar rats (250-300 g) were divided into 8 groups (n=10): Control, Sham, VAc, VA, PMa (0.5 mg/kg PM, intratracheal instillation), PMb (2...

The most important ingredients of saffron are crocin, crocetin, safranal, and picrocrocin. This study evaluated the protective effects of crocin against the inflammation, oxidative stress, and functional disturbances of the kidney induced by renal ischemia/reperfusion (I/R). MATERIALS AND METHODS: Different doses of crocin (0, 100, 200, and 400 mg/kg) were administered intraperitoneally 30 min before I/R...

OBJECTIVES: Epilepsy establishment gives rise to biochemical and morphological changes in the hippocampus. Oxidative stress, morphological changes, and mossy fiber sprouting (MFS) in the hippocampus underpin the epilepsy establishment. Eugenol is the main component of the essential oil extracted from cloves with the potential to modulate neuronal excitability. Therefore, we investigated the effect of eugenol on convulsive behavior, oxidative stress, and histological changes of the hippocampus in lithium-pilocarpine model of epilepsy...

Multiple sclerosis is a debilitating disease of the central nervous system. It affects people of all ages but is more prevalent among 20-40 year olds. Patients with MS can be presented with potentially any neurological symptom depending on the location of the lesion. A quarter of patients with MS suffer from bilateral lower limb spasticity among other symptoms. These devastating effects can be detrimental to the patient's quality of life. Hematopoietic stem cells (HSCs) have been used as a treatment for MS over the past 2 decades but their safety and efficacy has are undetermined...

OBJECTIVES: The use of antisense oligonucleotides (AOs) to restore normal splicing by blocking the recognition of aberrant splice sites by the spliceosome represents an innovative means of potentially controlling certain inherited disorders affected by aberrant splicing. Selection of the appropriate target site is essential in the success of an AO therapy. In this study, in search for a splice model system to facilitate the evaluation of AOs to redirect defective splicing of IVSI-110 β-globin intron, an EGFP-based IVSI-110 specific cellular reporter assay system has been developed and a number of AOs were tested in this cellular splicing assay...
