The Impact of First Complete Remission by PET-CT and Time to Next Treatment on Survival of Follicular Lymphoma Patients.

We retrospectively analyzed the impact of initial positron emission tomography and computed tomography (PET-CT) complete remission (CR) and time to next treatment (TTNT) on patient outcome in follicular lymphoma. Between 2002 and 2014, 150 patients could be evaluated for treatment response and long-term outcome. The CR after first line treatment with either rituximab-cyclophosphamide, oncovin, and prednisolone (R-COP) or rituximab-cyclophosphamide, doxorubicin, oncovin, and prednisolone (R-CHOP) was 89% and partial response (PR) was 7%.

Involvement of increased p53 expression in the decrease of mitochondrial DNA copy number and increase of SUV of FDG-PET scan in esophageal squamous cell carcinoma.

We appraised Warburg effect through analysis of mitochondrial DNA (mtDNA) copy number and maximum standard uptake value (SUV) of F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan and their alterations in esophageal squamous cell carcinoma (ESCC). Later T-status and longer longitudinal tumor length were associated with lower mtDNA copy number (p < .05) but higher SUV-ESCC (p < .

A Microchip Electrophoresis Device Integrated with the Top-bottom Antiparallel Electrodes of Indium Tin Oxide to Detect Inorganic Ions by Contact Conductivity.

A microchip electrophoresis (ME) device with off-channel contact conductivity detection (CD) was constructed using top-bottom antiparallel indium tin oxide (ITO) electrodes and a cross-type microchannel. The 500-m wide top-bottom antiparallel decouplers were found to effectively decrease the interference of the electrophoretic current. The cross-type microchannel was formed by bonding the patterned negative photoresist microstructures and the two top-bottom opposed ITO-deposited glass substrates.

An electrooxidative technique to fast fabricate copper phosphate electrodes capable of integrating high performance liquid chromatography for the label-free detection of fish freshness.

A simple and fast one-step electrooxidative method has been developed to monolithically produce a copper phosphate (Cu(PO)) compound on a disposable copper tape, which can be integrated with high performance liquid chromatography (HPLC) for the estimation of fish freshness. The Cu(PO) compound of flake-like nanostructures was formed by applying a first anodic peak potential at the copper tape for 10 min in a 1 M sodium dihydrogen phosphate (NaHPO) (pH 5.0) solution.

Prognostic role of initial pan-endoscopic tumor length at diagnosis in operable esophageal squamous cell carcinoma undergoing esophagectomy with or without neoadjuvant concurrent chemoradiotherapy.

Background: The objective of this study was to appraise the prognostic role of initial pan-endoscopic tumor length at diagnosis within or between operable esophageal squamous cell carcinoma (ESCC) undergoing upfront esophagectomy or neoadjuvant concurrent chemoradiotherapy (nCCRT) followed by esophagectomy.

Methods: Between Jan 2001 and Dec 2013 in Koo-Foundation Sun Yat-sen Cancer Center in Taiwan, 101 ESCC patients who underwent upfront esophagectomy (surgery group) and 128 nCCRT followed by esophagectomy (nCCRT-surgery group) were retrospectively collected. Prognostic variables, including initial pan-endoscopic tumor length at diagnosis (sub-grouped ≤3, 3-5 and >5 cm), status of circumferential resection margin (CRM), and pathological T/N/M-status and cancer stage, were appraised within or between surgery and nCCRT-surgery groups.

Radical Lymph Node Dissection in Primary Esophagectomy for Esophageal Squamous Cell Carcinoma.

Background: Subtotal esophagectomy with radical lymph node dissection (RLND) remains an effective therapeutic strategy for localized esophageal squamous cell carcinoma (ESCC). However, controversy exists regarding the extent to which RLND should be performed. We reappraised the prognostic impact and accurate nodal staging of RLND in ESCC.

Active targeted drug delivery for microbes using nano-carriers.

Although vaccines and antibiotics could kill or inhibit microbes, many infectious diseases remain difficult to treat because of acquired resistance and adverse side effects. Nano-carriers-based technology has made significant progress for a long time and is introducing a new paradigm in drug delivery. However, it still has some challenges like lack of specificity toward targeting the infectious site.

Nasopharyngeal alveolar rhabdomyosarcoma expressing CD56: a mimicker of extranodal natural killer/T-cell lymphoma.

Alveolar rhabdomyosarcoma (ARMS) is remarkably rare in adults older than 45 years. Histologically, the tumor is composed of blue round cells with frequent expression of CD56 in addition to myogenic markers. Recent studies of ARMS have shown two specific recurrent translocations: PAX3-FKHR [t(2;13)(q35;q14)] or PAX7-FKHR [t(1;13)(p36;q14)].

The prognostic value of circumferential resection margin in esophageal squamous cell carcinoma after concurrent chemoradiation therapy and surgery.

Background: Despite the significant advances in surgical techniques and multimodality treatments for esophageal cancer, the overall survival remains unsatisfactory. During the past years, efforts were made to determine the prognostic factors that would help in identifying patients suitable for surgery or guiding adjuvant therapy. Positive circumferential resection margins (CRMs) in esophageal cancer have been previously linked with poor prognosis, but their impact on survival remains controversial in patients treated by a multimodality protocol.

Multiscale sample entropy based on discrete wavelet transform for clinical heart rate variability recognition.

Traditional multiscale method uses coarse grained average (CGA) to evaluate sample entropy (SE) parameters in different scales for signal characterization. In this study, we propose to use discrete wavelet transform (DWT) to decompose hear rate variability signals into multiscale sequences for the calculation of SE features for the recognition of congestive heart failure (CHF) and atrial fibrillation (AF) from normal sinus rhythm (NSR). The support vector machine (SVM) is used as the classifier and the capability of the features are justified with leave-one-out cross-validation method.

Bispectral analysis and genetic algorithm for congestive heart failure recognition based on heart rate variability.

This paper proposes a congestive heart failure (CHF) recognition method that includes features calculated from the bispectrum of heart rate variability (HRV) diagrams and a genetic algorithm (GA) for feature selection. The roles of the bispectrum-related features and the GA feature selector are investigated. Features calculated from the subband regions of the HRV bispectrum are added into a feature set containing only regular time-domain and frequency-domain features.

Multimodality treatment and long-term follow-up of the primary pulmonary lymphoepithelioma-like carcinoma.

Introduction: Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is a very rare subtype of non-small-cell lung cancer. Most cases are reported in Southeast Asia and are associated with Epstein-Barr virus infections. Because of its rare incidence, the optimal treatment and the results of long-term follow-up are not well understood.

Conditional mutual information-based feature selection for congestive heart failure recognition using heart rate variability.

Feature selection plays an important role in pattern recognition systems. In this study, we explored the problem of selecting effective heart rate variability (HRV) features for recognizing congestive heart failure (CHF) based on mutual information (MI). The MI-based greedy feature selection approach proposed by Battiti was adopted in the study.

Epigenetic therapy using the histone deacetylase inhibitor for increasing therapeutic gain in oral cancer: prevention of radiation-induced oral mucositis and inhibition of chemical-induced oral carcinogenesis.

In addition to genetic changes, epigenetic aberrations also play important roles in radiation- and chemical-induced disorders and carcinogenesis. The present study investigated whether epigenetic therapy with a histone deacetylase (HDAC) inhibitor has dual benefits for radiation-induced oral mucositis and chemical-induced oral carcinogenesis, which should be treated at the same time. The HDAC inhibitor phenylbutyrate was first tested to determine if it influences DNA damage repair and survival in irradiated normal cells in vitro by investigating the patterns and dynamics of phospho-gammaH2AX foci, Rad51 foci and phospho-gammaH2AX/Rad51 colocalization and using the comet and clonogenic assays.
