Targeting liver tumors with hyperthermia: Ferromagnetic embolization in a rabbit liver tumor model

“…With the hepatic artery clamped, the cystic artery was catheterized up to its junction with the hepatic artery with a single lumen polyethylene tube (od 0.8 mm, id 0.5 mm) attached to a 1 ml syringe. The ferromagnetic suspension was heated to 40 C in a water bath prior to infusion to improve the¯ow through the catheter. After agitation on a vortex, the appropriate volume of suspension was steadily infused in 0.5 ml aliquots with a heparinized saline¯ush of 0.25 ml immediately after each aliquot.…”

“…The tumor, adjacent NHP, and distant NHP were then weighed and digested in acid. The resulting solutions were analyzed for iron content by inductively coupled plasma atomic emission spectrometry (ICP-AES) [40]. This enabled the average iron concentration in the tumor, adjacent NHP, and distant NHP to be calculated in milligrams of iron per gram of liver tissue.…”

Studies on growth, crystal structure and characterization of novel organic nicotinium trifluoroacetate single crystals

“…Another important observation is that, there is no phase transition till the material melts and this enhances the temperature range for the utility of the crystal for NLO applications. The absence of water of crystallization in the molecular structure is indicated by the absence of the weight loss near 100 o C. Further there is no decomposition near the melting point [31]. This ensures the suitability of the material for possible application in lasers, where the crystals are required to withstand high temperatures.…”

Development and Validation of UV-Spectrophotometric Method for Estimation of Metformin in Bulk and Tablet Dosage Form

“…Activation of AMPK plays a vital role in these processes. 1,2 Literature survey revealed that reports on analytical methods such as UV-Visible, HPLC, LC-MS, LC-MS/MS and HPTLC for the determination of Metformin HCl from the bulk and dosage form, very few analytical methods reported for Metformin HCl. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Moreover reported methods were not much cost-effective in terms of solvent consumption.…”
