and glandular differentiation occurs later within the tumor.[ 6 , 7 , 18 , 19 , 20 ] Last but not least, a collision concept has been proposed, in which ASC comes from two individual stem cells that simultaneously and independently undergo malignant transformation.[ 21 , 22 ] Histopathology ASC has various macroscopic tumor types, such as ulcerative, medullary, intraluminal, polypoid and sclerotic, and upon macroscopic inspection, it is indistinguishable from SCC.[ 5 , 6 ] Microscopically, it is characterized by an AC and a SCC component that either have

Abstract

Hemoptysis is the predominant symptom of tuberculosis and is considered as important clue toward evaluation of tuberculosis and treatment accordingly, especially in high burden countries like India where disease is endemic. 8-25% cases of pulmonary tuberculosis are having hemoptysis during course of their illness. Unexplained hemoptysis with normal chest radiograph needs further evaluation including CT thorax and bronchoscopy. Bronchoscopy would be ideal choice for confirming diagnosis and to localize exact site of bleeding as well. In this case report, we describe a case of a young male who presented with cough and intermittant hemoptysis. During fiberoptic video-bronchoscopy we noted exophytic endobronchial growth in right main stem bronchus. Histopathological evaluation suggests mucoepidermoid carcinoma (MEC) of salivary gland type originating from main stem bronchus right side. PAS and mucicarmine staining differentiated MEC from Adenocarcinoma in our case.

GBM cancer stem cells Histopathologically, GBM can be distinguished from low-grade gliomas by area of necrosis, microvascular hyperplasia, and pseudopalisades of cells migrating away from the area of necrosis.[ 25 ] These pseudopalisades are located at the cortex–tumor junction, and migrate away from hypoxic and necrotic core. The histologic presentation of microvascular hyperplasia and necrosis may be essential in understanding the infiltrative nature of GBMs. It has been shown recently that cancer stem cells (CSCs) are able to initiate phenotypically human

Introduction In the recent years, our studies have demonstrated that T cells were hyperfunctional in patients with acquired aplastic anemia (AA). The excessive apoptosis of hematopoietic stem cells caused by cytotoxic T cells and/or lymphokines is the main pathogenesis of acquired AA. Up to now, acquired AA has been recognized by some scholars as an autoimmune disease with bone marrow (BM) as target organ attacked by the activated T lymphocytes. Therefore, immunosuppressive therapy (IST) has become the best choice for the treatment of acquired AA if there is

patients and not to be routinely used in ARDS.[ 27 ] Experimental trials In experimental models of ARDS in rats, bone-marrow derived mesenchymal stem cells (MSCs) reduce the severity of ventilator-induced lung injury by enhancing the regeneration of lung tissue and its repair [ 28 , 29 ]. Studies have shown that MSCs could be of benefit by their property to reduce the production of inflammatory mediators, leukocyte infiltration, tissue injury, and pulmonary failure.[ 30 ] Conclusion There has been considerable research on ARDS in the past decade and

not fully elucidated, the consensus is that AA is related to the abnormal immunity, defected hematopoietic microenvironment, shortage or dysfunction of hematopoietic stem cell, as well as genetic abnormality. Large numbers of studies have proved that T lymphocytes have a close relationship with hematopoietic failure.[ 8 ] Based on this, the extensive application and good efficacy of immunosuppressive also confirmed the significance of immunopathology in the development of aplastic anemia.[ 9 , 10 ] The importance of bone marrow to functional qi and blood had been
