Metabolomics is the study of all the metabolites using LC-MS and (1)HNMR spectroscopy with chemometric techniques. The stages of colon cancer were detected from patients' sera using (1)HNMR. MATERIALS AND METHODS: Five ml blood was collected from 16 confirmed patients referred for colonoscopy. One group of eight patients were diagnosed with stage 0 to I colon cancer and the second group of 8 patients with II-IV stage colon cancer...

OBJECTIVES: Naringin, an essential flavonoid, inhibits inflammatory response and oxidative stress in diabetes. However, whether naringin has beneficial effects on diabetic retinopathy (DR) remains unknown. MATERIALS AND METHODS: Streptozotocin (STZ, 65 mg/kg) was intraperitoneally injected into male rats (8 weeks old weighting 200-250 g) to establish diabetic model, then naringin (20, 40 or 80 mg/kg/day) was intraperitoneally injected into the diabetic rats for twelve weeks...

OBJECTIVES: Chondroitinase ABC (cABC) treatment improves functional recovery following spinal cord injury (SCI) through degrading inhibitory molecules to axon growth. However, cABC involvement in other pathological processes contributing to SCI remains to be investigated. Here, we studied the effect of cABC I on oxidative stress and inflammation developed in a rat model of SCI. MATERIALS AND METHODS: Male rats (220-250 g) were divided into three groups (n=28) including rats that underwent SCI (SCI group), rats subjected to SCI and received an intrathecal injection of phosphate buffer saline (SCI+PBS group), and rats that underwent SCI and received cABC intrathecally (SCI+E group)...

OBJECTIVES: MicroRNAs (miRNAs) are considered as powerful, post-transcriptional regulators of gene expression in hepatocellular carcinoma cells (HCC). However, the function of miR-92a is still unclear in HCC. MATERIALS AND METHODS: Expression of miR-92a in human HCC cell lines was evaluated using qRT-PCR. MTT assay and transwell assay were used to examine the function of miR-92a in HepG2 and Huh7 cells.

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...

OBJECTIVES: Crocus sativus (saffron) has been widely used in traditional medicine. It has also been found to possess many beneficial properties in modern medicine. 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...

OBJECTIVES: Non-invasive treatment options for retinoblastoma (RB), the most common malignant eye tumor among children, are lacking. Epithelial growth factor receptor (EGFR) accelerates cell proliferation, survival, and invasion of many tumors including RB. However, RB treatment by targeting EGFR has not yet been researched. In the current study, we investigated the effect of EGFR down-regulation on RB progression using shRNA lentiviral vectors. MATERIALS AND METHODS: EGFR expression in Weri-Rb-1 cells was down-regulated by EGFR shRNA-bearing lentiviral vectors...

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...
