TL;DR: It is shown that the histologic categorization of adult renal epithelial neoplasms performed by routine light microscopic hematoxylin and eosin-based examination in accordance with the contemporary classification scheme has prognostic utility.

TL;DR: The 1997 TNM classification of renal cell carcinoma appears to be equivalent to the previous classification in predicting outcome but permits better stratification of cases according to survival and, therefore, may have improved clinical usefulness.

TL;DR: CK19 is a powerful predictor of survival and can potentially segregate benign and malignant PETs, and all PETs with any one of the following features be diagnosed as malignant: presence of necrosis, vascular invasion, perineural invasion, or CK19 positivity are suggested.

TL;DR: ICs are universally present in deep esophageal LMs, and thus these neoplasms could be mistaken for gastrointestinal stromal tumors, particularly on biopsy samples, an error associated with adverse clinical consequences.

Abstract: Powders of calcium hexaferrites doped with Zirconium Cobalt CaFe11(ZrCo)O19 and CaFe10(ZrCo)2O19 have been synthesized. The nitrates are used as oxidants accompanied with urea as a fuel. Conventional Sol-gel technique is improved by replacing conventional heating furnace by a microwave source, hence the method is named as ‘The Microwave Induced sol-gel combustion route’ [1,2]. Structural analysis of the synthesized powders have been carried out using X-ray diffraction spectroscopy (XRD)& Morhological study is done using Transmission electron microscopy (TEM). Values of Lattice parameters (a, c) confirms the formation of Hexaferrite unit cell [3]. TEM imaging demonstrate the formation of nanosize particles. Variatoin of loss tangent (tan ) is studied as a function of frequency using precision impendence Analyser. Value of DC electrical resistivity (ρ) is also determined for the samples. Response to the external applied magnetic field is studied using Vibrating sample magnetometer (VSM), which show the moderate values of saturation magnetization (Ms), Remenace (Mr) and Coercivity (Hc). These nano sized materials with high resistivity are reported to be useful specially for the many Microwave absorbing applications. Also the reduction of particle size of hexaferrites to nanorange helps to improve magnetic and electric properties mentioned earlier. 1.Introduction In modern technoscientific era, the industrial application of nano materials has grabbed a principal importance owing to their improved electric and magnetic characteristics. Hexagonal ferrites especially Mtype ferrites have been proved to be the promising candidates for nano materials due to their ease of applicability in high density recording media, microwave absorption devices, magneto-optic recording media, etc. Ferrite is a very important class of magnetic oxides which contains
