Acute myeloid leukemia and myelofibrosis: Simultaneous transformation of essential thrombocythemia during treatment with hydroxyurea.

Essential thrombocytosis (ET) is usually an indolent disease but can uncommonly evolve into acute myeloid leukemia (AML) with a grim prognosis of 2-7 months. Studies report a lower incidence of leukemic transformation when compared to fibrotic transformation. The risk of transformation depends on the age, duration of disease, and tumor biology.

A Rare Case of Invasive Keratinizing Squamous Cell Carcinoma of the Foot.

Lower extremity soft-tissue lesions are frequently encountered in clinical practice. Cellulitis, osteomyelitis, and diabetic foot ulcerations remain the top differentials. The acuity of illness, imaging studies, and deep wound cultures are helpful in most cases.

Mystery of neck lump: an uncommon presentation of urachal cancer.

We present the case of a 55-year-old male patient who presented with palpable cervical lymphadenopathy. Excisional biopsy showed metastatic adenocarcinoma of unknown origin. Imaging showed a bladder mass following which he underwent transurethral resection of bladder tumour.

Primary endobronchial amyloidosis: A rare case of endobronchial tumor.

Primary localized endobronchial amyloidosis is a rare entity, as pulmonary amyloidosis most commonly occurs as a part of systemic AL amyloidosis. It can be asymptomatic or can present with nonspecific symptoms such as progressive dyspnea, cough, wheezing and rarely respiratory failure. It is frequently misdiagnosed as asthma, COPD or pneumonia.

Changes of red blood cell surface markers in a blood doping model of neocytolysis.

Background: Neocytolysis, the selective hemolysis of young circulating red blood cells (RBCs), contributes to the physiologic control of red cell mass and to pathophysiologic phenomena such as anemia of renal disease, anemia after spaceflight, and blood doping by athletes. Progress in understanding the process is hampered by the lack of established markers to distinguish young from older RBC.

Methods: Twelve potentially informative RBC surface markers were assayed by flow cytometry in normal blood samples, and 4 were preferentially expressed in young RBC.

Infiltrating myoepithelial carcinoma of the breast, a case report and cytologic-histologic correlation.

Introduction: Infiltrating myoepithelial carcinoma remains a rarely encountered lesion of the breast. The few cases that have surfaced firmly document the histopathology of this tumor, but its cytologic characteristics seemingly have been described in only one other report.

Case Presentation: Here we present the cytologic findings from a case of infiltrating myoepithelial carcinoma of the breast in a 52-year-old female and provide a histologic correlation with the subsequent biopsy and mastectomy specimens.

[Determination of chlorophenols in drinking water by headspace solid phase microextraction and gas chromatography].

Objective: To study the method for determination of chlorophenols in drinking water by headspace solid phase microextraction and gas chromatography.

Methods: Chlorophenols in water samples was extracted using optimized SPME technology, separated by HP-5 chromatigraphic column and the concentration of chlorophenols was determined by electron capture detector (ECD).

Results: The detection limit of MCP, DCP, TCP, PCP were 60.

Transplant-related bronchiolitis obliterans (BOS) demonstrates unique cytokine profiles compared to toxicant-induced BOS.

Bronchiolitis obliterans (BOS - bronchiolitis obliterans syndrome - clinical diagnosis; CBO-histopathologic diagnosis), is a chronic disease process of fibrosis and cellular deposition in airways, complicating long term survival following lung transplantation. BOS is also the result of sporadic toxicant exposure, with airway signs, symptoms, and histology indistinguishable from allograft rejection. This study establishes a transplant BOS model in MHC-mismatched rats and compares their cytokine profiles and histopathology to that of our established toxicant-induced BOS model.

[Study on removal of arsenic in drinking water by metal loaded materials].

Objective: To study the effect of metal loaded multiporous materials on the removal of arsenic in drinking water.

Methods: Metal loaded materials were manufactured using active carbon, active alumina, silica gel and macroporous resin etc. as carriers and iron salts and zirconium salts etc.

[Development and evaluation of a composite structural filter for removal of arsenic in drinking water].

Objective: To develop a composite structural filter and evaluate its performance on-site for removal of high level arsenic in drinking water.

Methods: Composite filters were manufactured using iron loaded carbon powder and superfine PE resin as main components. Test water was prepared by spiking arsenic in raw drinking water.

[Review of infrared spectroscopy for water cluster].

The explanation of structure and binding properties of small clusters provides a key for understanding bulk water in its liquid and solid phase and for understanding solvation phenomena. The progress, characteristic of the investigation on water clusters by Infrared are introduced. The results of far-infrared laser vibration-rotation-tunneling spectroscopy (FIR-VRT) and infrared spectroscopy of size-selected water are outlined in detail, and compared with those of other methods.
