Unique cytological features and chromosome aberrations in chondroid lipoma: a case report based on fine-needle aspiration cytology, histopathology, electron microscopy, chromosome banding, and molecular cytogenetics

Chondroid lipoma is a rare, benign tumor that may mimic soft-tissue sarcoma clinically. Its histopathologic features may resemble hibernoma, myxoid liposarcoma, myxoid chondrosarcoma, and other lipomatous or chondroid neoplasms. In this study, a chondroid lipoma was analyzed by fine-needle aspiration cytology, histopathology, electron microscopy, chromosome banding, and metaphase fluorescence in s

Altered AP-1/Ref-1 redox pathway and reduced proliferative response in iNOS-deficient vascular smooth muscle cells

We previously reported that injury-induced medial vascular smooth muscle cell (VSMC) proliferation and neointima formation in carotid arteries of inducible nitric oxide synthase knockout ( iNOS KO) mice were significantly reduced compared with wild type (WT). However, the molecular pathway underlying such differences is not known. In this in vitro study, we discovered that the AP-1/Ref-1/thioredox

Mutated V-H genes and preferential V(H)3-21 use define new subsets of mantle cell lymphoma

Mantle cell lymphoma (MCL) is believed to originate from a naive B cell. However, we recently demonstrated that a subset of MCL displayed mutated V-H genes. We also reported restricted use of certain V-H genes. To assess the prognostic impact of these new findings, we performed V-H gene analysis of 110 patients, revealing that 18 (16%) patients had mutated and 92 (84%) patients had unmutated V-H g

Characterization of a transient collisional Ni-like molybdenum soft x-ray laser pumped in grazing incidence

We present experimental results from an extensive investigation of a Ni-like Mo X-ray laser pumped in the transient regime and GRIP configuration (GRazing Incidence Pumping). The pump laser is a 10 Hz, 1 J, Ti:Sa laser system. The main diagnostic is a monochromatic near-field imaging system with a 1.7 micron spatial resolution that shows the soft x-ray laser source size and position relative to th

Hyperpolarized (3)He apparent diffusion coefficient MRI of the lung: Reproducibility and volume dependency in healthy volunteers and patients with emphysema.

PURPOSE: To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) (3)He gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and examine the reproducibility and volume dependency. MATERIALS AND METHODS: A total of eight healthy volunteers and 16 patients with emphysema were examined after inhalation of HP (3)He gas mixed with nitrogen (N(2)) during b

Regulatory T cells and the control of modified lipoprotein autoimmunity-driven atherosclerosis.

It has long been recognized that arterial inflammation plays a key role in the development of atherosclerosis. More recent evidence has suggested that this inflammation is modulated by autoimmune responses against modified self-antigens, such as oxidized low-density lipoprotein, in the vascular wall. However, the role of the immune system in atherosclerosis appears to be more complex than in class

Methods for detailed histopathological investigation and localization of biopsies from cervix uteri to improve the interpretation of auto fluorescence data

Fluorescence spectroscopy is one of many optical methods that are potentially clinically useful for noninvasive detection and characterization of disorders on the cervical part of uterus, including precancerous lesions. The cervix uteri exhibits a biologically complex tissue and the morphology of a biopsy is generally not homogenous. The standard histopathological protocol accounts only for the mo

Establishment of the first World Health Organization International Genetic Reference Panel for quantitation of BCR-ABL mRNA.

Serial quantitation of BCR-ABL mRNA levels is an important indicator of therapeutic response for patients with chronic myelogenous leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, but there is substantial variation in the real-time quantitative polymerase chain reaction methodologies used by different testing laboratories. To help improve the comparability of results bet

Total desmosines in plasma and urine correlate with lung function.

To evaluate the relationship between the matrix degradation biomarkers, desmosine and isodesmosine (desmosines), and lung function.Plasma and creatinine-corrected urinary total desmosines (P- and U-desmosines), lung function and carbon monoxide diffusion capacity (DL,CO) were measured in a cohort of subjects from the Swedish Twin Registry.Concentrations of U- and P-desmosines were measured in 349

PROlocalizer: integrated web service for protein subcellular localization prediction.

Subcellular localization is an important protein property, which is related to function, interactions and other features. As experimental determination of the localization can be tedious, especially for large numbers of proteins, a number of prediction tools have been developed. We developed the PROlocalizer service that integrates 11 individual methods to predict altogether 12 localizations for a

Incidence Trends in the Diagnosis of Giant Cell Tumor of Bone in Sweden Since 1958.

The Swedish Cancer Registry (founded in 1958) constitutes a unique resource for epidemiological studies of giant cell tumor of bone with potential for use for population-based studies of incidence over time. The aim of this study was to provide what we believe is the first modern population-based assessment of the incidence trends of giant cell tumor, a unique osteoclastogenic lytic stromal tumor

Small Cell Lung Cancer in a 14-year-old Girl.

Pediatric lung cancer is uncommon, and small cell lung cancer (SCLC) is exceptionally rare. A 14-year-old previously healthy girl was diagnosed with limited-stage SCLC, which was considered inoperable. She responded well to chemotherapy with carboplatin and etoposide, and surgical resection was performed after 2 cycles. High-dose thoracic radiotherapy in combination with etoposide and carboplatin
