A new sensitive and selective detection of Ga by thiophene-based 'turn-on' fluorescent chemosensor.

We designed a thiophene-based fluorescent chemosensor DHTC ((E)-2-([3,5-dichloro-2-hydroxybenzylidene]amino)thiophene-3-carboxamide) for detecting gallium (Ga ). DHTC could probe Ga using fluorescence enhancement. The limit of detection for Ga by DHTC was 0.

Highly Selective Detection of Al by Carboxamide-Based Fluorescent Chemosensor.

We designed a carboxamide-based fluorescent chemosensor HTPQ ((E)-2-(((8-hydroxy-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-yl)methylene)amino)thiophene-3-carboxamide) for detecting Al. HTPQ could probe Al by fluorescence enhancement. Limit of detection for Al toward HTPQ was 1.

Prognostic implication of FEV1/FVC ratio for limited-stage small cell lung cancer.

Background: A proportion of patients with chronic obstructive pulmonary disease (COPD) may progress rapidly to small cell lung cancer (SCLC). As the forced expiratory volume in 1 second (FEV1)/forced volume vital capacity (FVC) ratio is usually impaired in patients with COPD, and given that the FEV1 and FVC are not necessarily related to lung cancer development, we performed this study to test our hypothesis that the FEV1/FVC ratio predicts survival of patients with limited-stage (LS)-SCLC.

Methods: We assessed 74 patients with LS-SCLC treated with chemoradiotherapy.

Prognostic factors and treatment outcome after radiotherapy in cervical cancer patients with isolated para-aortic lymph node metastases.

Objective: The purpose of the present study was to evaluate treatment outcomes and prognostic factors in cervical cancer patients with isolated para-aortic lymph node (PALN) metastases. We especially tried to evaluate PALN factors such as size, site and number.

Methods: From August 1994 to December 2009, 40 cervical cancer patients with isolated PALN node metastases at initial diagnosis were selected for analysis.

Can initial diagnostic PET-CT aid to localize tumor bed in breast cancer radiotherapy: feasibility study using deformable image registration.

Background: Localization of the tumor bed of breast cancer is crucial for accurate planning of boost irradiation. Lumpectomy cavity and surgical clips provide localizing information about tumor bed. However, defining the tumor bed is often difficult because of presence of unclear lumpectomy cavity and lack of certain information such as absence of surgical clips.
