The 60 GHz wireless technology holds great potential for multi-Gbps communications and high-precision radio sensing. But the lack of an accessible experimental platform has been impeding its progress. In this paper, we overcome the barrier with OpenMili, a reconfigurable 60 GHz radio architecture. OpenMili builds from off-the-shelf FPGA processor, data(More)
The high concentrations of polybrominated diphenylethers (PBDEs) in the environment have raised the need for generating more information about the impact of these substances on animals. To study the distribution of (14)C-labelled 2,2',4,4',5-pentabromodiphenyl ether ((14)C-BDE-99) in Xenopus tropicalis (West African clawed frog) (14)C-BDE-99 was(More)
INTRODUCTION Mycobacterium marinum has emerged as a suitable species for induction of tuberculosis-like disease in zebrafish, and various zebrafish models (larval and adult) for drug screening have been proposed in the literature. It is believed that an adult zebrafish model is more useful in drug screening because, apart from assessment of efficacy, one(More)
A strategy based on Pd-mediated ring closure of 1,2-disubstituted indoles containing an unactivated olefin leading to indole-1,2-fused 8- and 9-membered rings has been developed for the identification of new and potential scaffolds for apoptosis. A large number of fused indole derivatives containing an endocyclic double bond were synthesized using this(More)
INTRODUCTION Recent studies have shown the utility of adult zebrafish ECG (electrocardiogram) in assessing drug-induced QTc prolongation. While the method has significant advantages over current ECG animal models including ethical issues, low compound requirement and expense, adoption of the method into drug discovery programs has been hampered by specific(More)
Aberrant increases in NMDA receptor (NMDAR) signaling contributes to central nervous system sensitization and chronic pain by activating neuronal nitric oxide synthase (nNOS) and generating nitric oxide (NO). Because the scaffolding protein postsynaptic density 95kDA (PSD95) tethers nNOS to NMDARs, the PSD95-nNOS complex represents a therapeutic target.(More)
Antibiotics with good therapeutic value and novel mechanism of action are becoming increasingly important in today's battle against bacterial resistance. One of the popular targets being DNA gyrase, is currently becoming well-established and clinically validated for the development of novel antibacterials. In the present work, a series of forty eight(More)
BACKGROUND AND METHODS We describe a method for obtaining pharmacokinetics (PK) and pharmacology data from adult zebrafish in terms of mg/kg using a novel method of oral administration. Using carbamazepine (CBZ) as a test drug, we employed dried blood spot (DBS) cards to enable drug quantification for PK; and we evaluated the pharmacological anxiolytic(More)
DNA gyrase, the sole type II topoisomerase present in Mycobacterium tuberculosis, is absent in humans and is a well validated target for anti-tubercular drug discovery. In this study, a moderately active inhibitor of Mycobacterium tuberculosis GyrB, the pharmaceutically unexploited domain of DNA gyrase, was reengineered using a combination of molecular(More)
Recently numerous non-fluoroquinolone-based bacterial type II topoisomerase inhibitors from both the GyrA and GyrB classes have been reported as antibacterial agents. Inhibitors of the GyrA class include aminopiperidine-based novel bacterial type II topoisomerase inhibitors (NBTIs). However, inhibition of the cardiac ion channel remains a serious liability(More)
