The Gene Expression Barcode project, http://barcode.luhs.org, seeks to determine the genes expressed for every tissue and cell type in humans and mice. Understanding the absolute expression of genes across tissues and cell types has applications in basic cell biology, hypothesis generation for gene function and clinical predictions using gene expression(More)
The success of Mycobacterium tuberculosis as a pathogen derives from its facile adaptation to the intracellular milieu of human macrophages. To explore this process, we asked whether adaptation also required interference with the metabolic machinery of the host cell. Temporal profiling of the metabolic flux, in cells infected with differently virulent(More)
Silk cocoon membrane (SCM) is an insect engineered structure. We studied the electrical properties of mulberry (Bombyx mori) and non-mulberry (Tussar, Antheraea mylitta) SCM. When dry, SCM behaves like an insulator. On absorbing moisture, it generates electrical current, which is modulated by temperature. The current flowing across the SCM is possibly ionic(More)
We present a method for identifying biomarkers in human lung injury. The method is based on high-resolution nuclear magnetic resonance (NMR) spectroscopy applied to bronchoalveolar lavage fluid (BALF) collected from lungs of critically ill patients. This biological fluid can be obtained by bronchoscopic and non-bronchoscopic methods. The type of lung injury(More)
INTRODUCTION Measurement of pulmonary vascular resistance (PVR) is essential in evaluating a patient with pulmonary hypertension. MATERIAL AND METHODS Data from right heart catheterization (RHC) and echocardiograms performed within 90 days of each other on 45 non-consecutive adult patients were reviewed in this retrospective study. Patients were recruited(More)
Acute respiratory distress syndrome (ARDS) contributes substantially to mortality and morbidity in USA and worldwide. Due to limitations in early diagnostics of ARDS by classical methods, there has been need for discovery of novel methods and biomarkers for its characterization. We present here first high-resolution 1H nuclear magnetic resonance (NMR)(More)
Self-assembly of phenylalanine is linked to amyloid formation toxicity in phenylketonuria disease. We are demonstrating that L-phenylalanine self-assembles to amyloid fibrils at varying experimental conditions and transforms to a gel state at saturated concentration. Biophysical methods including nuclear magnetic resonance, resistance by alpha-phenylglycine(More)
respiratory distress syndrome (ARDS) is a serious lung injury and has low survival rates. More than 150,000 cases of ARDS are diagnosed every year in the US alone, according to the National Heart, Lung, and Blood Institute database. 1 H nuclear magnetic resonance (NMR) has been a well-established technique for the recognition of biomarkers in various body(More)
Proton NMR based metabolic profile of serum associated with different gallbladder pathologies is presented. Quantitative and qualitative variations in the metabolic profile of serum in control samples and three different pathologies of gallbladder, chronic cholecystitis, xanthogranulomatous cholecystitis and carcinoma of gallbladder has been evaluated by(More)
In vitro, high-resolution 31P NMR (Nuclear Magnetic Resonance) spectroscopy-based analysis of phospholipids in serum is well recognized in leukemia, lymphoma, non-hematological cancers and renal cell carcinoma. In context of these studies, phospholipids were analyzed in blood of thirty-two (n = 32) patients with Duchenne muscular dystrophy (DMD) (Age, Mean(More)
