Prior studies with carbonic anhydrase (CA) inhibitors implicated mitochondrial CA in ureagenesis and gluconeogenesis. Subsequent studies identified two mitochondrial CAs. To distinguish the contribution of each enzyme, we studied the effects of targeted disruption of the murine CA genes, called Car5A and Car5B. The Car5A mutation had several deleterious consequences. Car5A null mice were smalle...

Tumor markers are biochemical substances elaborated by tumor cells either due to the cause or effect of malignant processes. Here we investigated serum levels of cancer antigen (CA15.3) and carcino embryonic antigen (CEA) in 153 pre and post operated southern Indian breast cancer patients (stage-I- 45, stage-II-55, stage-III- 53 samples) and 37 normal controls.Patients with malignant lesions ha...

Previous work shows that higher levels of education quality (as measured by international student achievement tests) increases growth rates of national income. This paper begins by confirming those findings in an analysis involving more countries over more time with additional controls. We then use the panel structure of our data to assess whether the mechanism by which education quality appear...

Multiple sclerosis (MS) is a complex disease which is correlated with increasing inflammatory factors, demyelination and axonal loss. In this auto-immune disease, Neuroinflammation is mediated by different types of T cells with macrophage/microglial activation and B cells involvement that interact in a collaborative manner. Focal inflammation is the main cause for the onset of relapses and coul...

Despite the unprecedented popularity of separation chromatography, the measurement of coeluting isomeric chemicals remains an extremely difficult task. We developed an analytical scheme capable of measuring two coeluting isomers using a single chromatographic column and a gas chromatography/tandem mass spectrometry system. The protocol utilized two product ion fragments generated from a common ...

Catheter-ablation (CA) of consecutive left atrial tachycardias (LAT) can be challenging. Pulsed field ablation (PFA) yields a novel non-thermal CA technology for treatment fibrillation (AF). There is no data regarding PFA LAT. This study sought to investigate the outcome in LAT following prior AF. Consecutive patients with underwent ultra-high-density (UHDx) mapping. Subsequent identification A...

Amelogenesis imperfecta (AI) is group of inherited disorders resulting in enamel pathologies. The involvement of epigenetic regulation in the pathogenesis of AI is yet to be clarified due to a lack of knowledge about amelogenesis. Our previous genome-wide microRNA and mRNA transcriptome analyses suggest a key role for miR-153 in endosome/lysosome-related pathways during amelogenesis. Here we sh...
