The pathophysiology of the scorpion envenoming syndrome is reviewed with emphasis on the body systems commonly affected. Concepts of the mechanisms underlying venom action, as can be explained by the recently discovered effects on ionic channels, are discussed. The results of clinical analysis of cases of scorpion sting victims and animal experiments with(More)
6-[5-(4-Amidinophenyl)furan-2-yl]nicotinamidine (8a) was synthesized from 6-[5-(4-cyanophenyl)furan-2-yl]nicotinonitrile (4a), through the bis-O-acetoxyamidoxime followed by hydrogenation. Compound 4a was prepared via selective bromination of 6-(furan-2-yl)nicotinonitrile (2a) with N-bromosuccinimide, followed by Suzuki coupling with 4-cyanophenylboronic(More)
BACKGROUND AND OBJECTIVES Bacterial vaginosis is the most common cause of vaginal symptoms in women and has potential complications. Efforts to improve treatment of this disease process are warranted. GOAL OF THIS STUDY The goal of this study was to compare the safety and efficacy of once-daily intravaginal administration of 0.75% metronidazole gel for 5(More)
OBJECTIVE To report the short- to intermediate-term experience of using salvage targeted cryoablation of the prostate (TCAP) for the recurrence of localized prostate cancer after radiotherapy. PATIENTS AND METHODS Between May 2000 and November 2005, 100 patients had salvage TCAP for recurrent prostate cancer after radiotherapy; the mean follow-up was 33.5(More)
Nine fatal cases from the sting of the scorpion Leiurus quinquestriatus are presented. All victims showed association of CNS and cardiovascular manifestations. Either the CNS or the cardiovascular effects could occur first in the early phases of the scorpion envenoming syndrome; the CNS manifestations, however, always preceded the terminal hypotension and(More)
A series of biphenyl benzimidazoles diamidines 6a-i were synthesized from their respective diamidoximes, through the bis-O-acetoxyamidoxime followed by hydrogenation in glacial acetic acid/ethanol in the presence of Pd-C. The target compounds contain hydroxy and/or methoxy substituted 1,3-phenyl groups as the central spacer between the two amidino bearing(More)
Interactions between Z-disc proteins regulate muscle functions and disruption of these interactions results in muscle disorders. Mutations in Z-disc components myotilin, ZASP/Cypher, and FATZ-2 (calsarcin-1/myozenin-2) are associated with myopathies. We report here that the myotilin and the FATZ (calsarcin/myozenin) families share high homology at their(More)
Direct modulation of gene expression by targeting oncogenic transcription factors is a new area of research for cancer treatment. ERG, an ETS-family transcription factor, is commonly over-expressed or translocated in leukaemia and prostate carcinoma. In this work, we selected the di-(thiophene-phenyl-amidine) compound DB1255 as an ERG/DNA binding inhibitor(More)
Androctonus crassicauda venom has an i.v. LD50 in mice of 0.32 +/- 0.02 mg/kg, which makes the scorpion among the most toxic species in the world. Fifty-one non-fatal and one fatal cases of scorpion sting were presented. Pain and tenderness were very common following the sting. Generalized erythema occurred in 20-25% of all infants and children below the(More)
A series of phenyl-2,2'-bichalcophene diamidines 1a-h were synthesized from the corresponding dinitriles either via a direct reaction with LiN(TMS)₂, followed by deprotection with ethanolic HCl or through the bis-O-acetoxyamidoxime followed by hydrogenation in acetic acid and EtOH over Pd-C. These diamidines show a wide range of DNA affinities as judged(More)
