Clostridium thermocellum produces H2 and ethanol, as well as CO2, acetate, formate, and lactate, directly from cellulosic biomass. It is therefore an attractive model for biofuel production via consolidated bioprocessing. Optimization of end-product yields and titres is crucial for making biofuel production economically feasible. Relative protein expression(More)
Mucosal melanoma of the nasal cavity and paranasal sinuses is seldom encountered in routine ENT practice. These tumors have poor prognosis owing to higher rates of locoregional recurrence and distant metastasis. Various treatment modalities have been employed over time but the ideal treatment approach still remains an open issue. This article presents some(More)
We describe the practical implementation of a new RP (pH 10 - pH 2) 2D HPLC-ESI/MS scheme for large-scale bottom-up analysis in proteomics. When compared to the common SCX-RP approach, it provides a higher separation efficiency in the first dimension and increases the number of identified peptides/proteins. We also employed the methodology of our(More)
BACKGROUND Carcinoma is a rare complication of pharyngeal diverticula. There is a paucity of information about its incidence, presentation, management, and treatment outcomes. A systematic review and analysis of all reported cases has been carried out. METHODS A comprehensive literature search for pharyngeal diverticula carcinoma was performed from 1896(More)
The effects of leptin-replacement therapy on the plasma proteome of three unique adults with genetically based leptin deficiency were studied longitudinally during the course of recombinant human leptin-replacement treatment. Quantitative proteomics analysis was performed in plasma samples collected during four stages: before leptin treatment was initiated,(More)
Cystic swellings of the neck in children have limited differential diagnoses, often either lymphatic or vascular malformations. Other cystic inflammations can be the result of tuberculous abscesses, suppurated lymph nodes and actinomycosis. Microfilaria causing lmphadenovarix of head-neck region has not yet been described in the literature. A 10-year-old(More)
The wide dynamic range of proteins in biological samples poses a challenge for the detection of low-abundance proteins. Recently, combinatorial hexapeptide peptide libraries have been suggested as an approach to normalization of proteins in such mixtures. We examined the reproducibility of a commercial hexapeptide ligand library for quantitative and(More)
INTRODUCTION Although the clinical effects of infliximab therapy in rheumatoid arthritis have been documented extensively, the biological effects of this intervention continue to be defined. We sought to examine the impact of infliximab therapy on the serum proteome of rheumatoid arthritis patients by means of a mass spectrometry-based approach. METHODS(More)
