The study of oral premalignant lesions (OPL) is crucial to the identification of initiating genetic events in oral cancer. However, these lesions are minute in size, making it a challenge to recover sufficient DNA from microdissected cells for comprehensive genomic analysis. As a step toward identifying genetic aberrations associated with oral cancer progression, we used tiling-path array compa...

To establish a screening strategy for pancreatic cancer (PC) based on new-onset diabetic mellitus (NO-DM), serum metabolomics analysis and a search for the metabolic pathways associated with PC related DM were performed. Serum samples from patients with NO-DM (n = 30) and patients with pancreatic cancer and NO-DM were examined by liquid chromatography-mass spectrometry. Data were analyzed using...

We have studied the potential of mean force of two peptides, one known to adopt a -hairpin and the other an -helical conformation in solution. These peptides are, respectively, residues 41–56 of the C-terminus (GEWTYDDATKTFTVTE) of the B1 domain of protein G and the 13 residue C-peptide (KETAAAKFERQHM) of ribonuclease A. Extensive canonical ensemble sampling has been performedusing aparallel re...

Canine lymphoma is a common cancer that has high rates of complete remission with combination chemotherapy. However, the duration of remission varies based on multiple factors, and there is a need to develop a method for early detection of recurrence. In this study, we compared the metabolites profiles in serum from 21 dogs with lymphoma and 13 healthy dogs using gas chromatography mass spectro...

Survivin is a recently described inhibitor of apoptosis and mitotic regulator which is selectively over-expressed in human tumors. Its expression rate is predictive of disease progression, early recurrences and resistance to therapy. Up-regulation of survivin in oral pre-malignant lesions (OPL) and in oral squamous cell carcinoma (OSCC) has already been demonstrated in previous studies. A criti...

Purpose:Metabolomics depicts metabolic changes in biologic systems using a multiparametric analysis technique. This study assessed the metabolomic profiles of serum, obtained by proton nuclear magnetic resonance (NMR) spectroscopy, from cirrhotic patients with andwithout hepatocellular carcinoma (HCC). Experimental Design: The study included 154 consecutive patients with compensated biopsy-prov...

Molecular dynamics simulations of liquid ethanol at four thermodynamic states ranging from T ) 173 K to T ) 348 K were carried out using the transferable OPLS potential model of Jorgensen (J. Phys. Chem. 1986, 90, 1276). Both static and dynamic properties are analyzed. The resulting properties show an overall agreement with available experimental data. Special attention is paid to the hydrogen ...

Volatile organic compounds (VOCs) in Citrus sinensis ‘hongjiang’ oranges significantly vary depending on the fruit variety, cultivation mode, and location. The effect of these three factors VOCs was experimentally determined this study. In total, 102 were separated via headspace solid-phase microextraction identified gas chromatography-mass spectrometry, differential components analyzed by part...
