Teratocarcinosarcoma of the nasal cavity: challenges in the clinico-pathologic perspectives.

Objective: Clinicopathologic illustration of sinonasal teratocarcinosarcoma (SNTCS) in a middle-aged man, highlighting the difficulties and challenges encountered during surgical intervention, histopathologic diagnosis, and its overall management.

Methodology: Case report and literature review.

Results: A 40-year-old man having recurrent epistaxis for three months presented with a dark-colored protruding polypoid nasal mass.

Pathologist's perspectives on reporting of tumour budding in colorectal cancer.

Purpose: Tumour budding (TB) is an important adverse prognostic factor in colon cancer, which can also guide adjuvant treatment in stage II colorectal carcinoma. The International Tumor Budding Consensus Conference (ITBCC) recommended a three-tiered scoring system to streamline the scoring of budding across the globe. The goal of this survey is to understand the variation in reporting practice, globally.

Optimal Blending of PbSe and CdSe in Polycrystalline PbCdSe Nanocomposite Film: Improved Carrier Multiplication and Enhanced Photoconversion Efficiency.

The present work reports galvanostatic electro-co-deposition of -PbCdSe semiconductor (SC) films on FTO substrate from the respective precursors. Self-designed matrices were formulated at variable concentrations of Pb in the deposition medium. The semiconductor films constitute an intermixed structure of close-packed PbSe and CdSe nanoparticles (NPs), and the band gap () was effectively tuned in the range 0.

Reporting of tumor budding in colorectal adenocarcinomas using ×40 objective: A practical approach for resource constrained set-ups.

Context: Tumor budding (TBud) is recognized as a poor prognostic marker in colorectal cancer (CRC) with important treatment implications in Stage II cancers and malignant polyps. There are multiple propositions for bud count reporting but without an uniformly accepted system. The International TBud consensus conference (ITBCC) proposed mandatory reporting of budding on the single worst ×20 high power field (0.

Catalytic Intervention of MoO toward Ethanol Oxidation on PtPd Nanoparticles Decorated MoO-Polypyrrole Composite Support.

Ethanol oxidation reaction has been studied in acidic environment over PtPd nanoparticles (NPs) grown on the molybdenum oxide-polypyrrole composite (MOPC) support. The attempt was focused on using reduced Pt loading on non-carbon support for direct ethanol fuel cell (DEFC) operated with proton exchange membrane (PEM). As revealed in SEM study, a molybdenum oxide network exists in polypyrrole caging and the presence of metal NPs over the composite matrix is confirmed by TEM analysis.
