BACKGROUND To evaluate the efficacy of trypan blue (0.06%) in posterior capsulorhexis with optic capture in pediatric cataracts. METHODS In this prospective randomized controlled study, trypan blue dye assisted posterior capsulorhexis with optic capture was performed in 18 eyes (group 1) and no dye was used for posterior capsulorhexis (group 2) in 17 eyes. RESULTS The mean size of the poste...

Trypan blue treatment prevented tumor-specific rejec tion in three animal model systems.These included the spontaneous rejection of tumors of mice (UVT-2051) and guinea pig (line 1 hepatoma) as well as vaccine-induced rejection of a guinea pig tumor (line 10 hepatoma). Sec ondary immune reactions to line 10 cell challenges were not abolished by trypan blue treatment. Although trypan blue is a p...

BACKGROUND Safety is an important consideration for the clinical application of dendritic cells (DC) loaded with autologous tumor lysate (TL). Thus, avitalization of TL from living autologous tumor tissue has to be guaranteed. METHODS Composition of TL was investigated by static image analysis (SIA) with the Morphologi G3 device, which simultaneously measures size and shape of up to 100,000 p...

Mangiferin-mediated down-regulation of NFκB showed potential for chemotherapeutic agent-mediated cell death, suggesting a role in combination therapy for cancer. In this study the combined mechanism of the anticancer action of oxaliplatin and mangiferin was investigated. MTT dose response curves, trypan blue staining, caspase 3 assays as well as DNA cell cycle analyses were performed on HeLa, H...

BACKGROUND s/aims: Staining of internal limiting membrane with indocyanine green (ICG) has been reported to be associated with postoperative atrophic retinal pigment epithelium (RPE) change. Here the authors examined whether removing sodium from the solvent reduces ICG induced RPE cytotoxicity. METHODS Human RPE cells were exposed to ICG (0.25 and 0.025 mg/ml) reconstituted with balanced salt...

introduction: skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. the aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. methods: in this paper, s...

Prostaglandins (PGs) protect gastric mucosa against damage produced by acetylsalicylic acid (ASA). Whether this effect of prostaglandins is truly cytoprotective and whether cAMP plays an important role in this effect is uncertain. We studied the effect of: (1) 16,16 dimethyl prostaglandin E2 (dmPGE2), isobutylmethyl xanthine (IMX), and dibutyryl cAMP (DBcAMP) on ASA-induced damage to monolayer ...

Anthracyclines (AC) are antitumor antibiotics with significant activity against solid and hematologic malignancies. One problem preventing more widespread use has been the development of cardiac toxicity. Experimental evidence supports oxidant stress as an important trigger and/or mediator of AC-induced cardiotoxicity (ACT). Therefore, reducing oxidant stress should be protective against ACT. T...

OBJECTIVE Alkali metal appears to be a promising tool in thermochemical ablation, but, it requires additional data on safety is required. The objective of this study was to explore the effectiveness of permeable oil-packed liquid alkali metal in the thermochemical ablation of tumors. METHODS Permeable oil-packed sodium-potassium (NaK) was prepared using ultrasonic mixing of different ratios o...
