STUDY OBJECTIVE A cancer registry was analyzed to determine if the clinicopathologic characteristics, treatment modalities, and prognosis of non-small cell lung cancer (NSCLC) patients < 40 years of age at diagnosis differed from patients > 80 years of age at diagnosis. DESIGN Retrospective review of patients with NSCLC diagnosed between 1987 and 1996. (More)
Estimating the location of single molecules from microscopy images is a key step in many quantitative single molecule data analysis techniques. Different algorithms have been advocated for the fitting of single molecule data, particularly the nonlinear least squares and maximum likelihood estimators. Comparisons were carried out to assess the performance of(More)
OBJECTIVE Hepatocellular carcinoma is the most common malignancy in Taiwan, and spinal metastasis is a serious complication in cancer patients. In this study, we aimed to delineate the clinical features, evaluate the radiotherapy response and analyse the prognostic features in hepatocellular carcinoma subjects with spinal metastasis. METHODS From 1981 to(More)
PURPOSE To evaluate prospectively the efficacy of granulocyte-macrophage colony-stimulating factor (GM-CSF) in the reduction of chemotherapy-induced oral mucositis. PATIENTS AND METHODS Twenty patients with stage IV squamous cell carcinoma of head and neck were studied. Two-cycles (periods) of identical doses of cisplatin, fluorouracil (5-FU), and(More)
Single particle tracking in three dimensions in a live cell environment holds the promise of revealing important new biological insights. However, conventional microscopy-based imaging techniques are not well suited for fast three-dimensional (3D) tracking of single particles in cells. Previously we developed an imaging modality multifocal plane microscopy(More)
BACKGROUND AND STUDY OBJECTIVES Cardiac tamponade is a life-threatening complication of non-small cell lung cancer (NSCLC). Malignant pericardial effusion signifies advanced disease, but the significance of a negative pericardial fluid cytology in patients with advanced lung cancer is still controversial. The differential diagnosis of cytology-negative(More)
The high quantum efficiency of the charge-coupled device (CCD) has rendered it the imaging technology of choice in diverse applications. However, under extremely low light conditions where few photons are detected from the imaged object, the CCD becomes unsuitable as its readout noise can easily overwhelm the weak signal. An intended solution to this(More)
The fatty acid composition of Pseudomonas aeruginosa PAO1 was compared between biofilm and batch planktonic cultures. Strain PAO1 biofilms were able to maintain a consistent fatty acid profile for up to 6 days, whereas strain PAO1 batch planktonic cultures showed a gradual loss of cis-monounsaturated fatty acids over 4 days. Biofilms exhibited a greater(More)
Different techniques have been advocated for estimating single molecule locations from microscopy images. The question arises as to which technique produces the most accurate results. Various factors, e.g. the stochastic nature of the photon emission/detection process, extraneous additive noise, pixelation, etc., result in the estimated single molecule(More)
A study was undertaken to determine the prevalence and diversity of species of the genus Arcobacter in pig and dairy cattle manure, which led to the identification of strains AF1440T, AF1430 and AF1581. Initially identified as Arcobacter butzleri based on colony morphology and initial PCR-confirmation tests, analyses of 16S rRNA gene sequences of these(More)
