Introduction: Anethole is the main constituent of Pimpinella anisum L. (anise), a herbaceous annual plant which has several therapeutic effects. In the folk medicine, anise is employed as an antiepileptic drug. Specifically, this study was focused on the cellular effect of anethole, an aromatic compound in essential oils from anise and camphor. Anethole has various physiological effects on t...

The aim of this study was to identify the antiviral mechanism of a novel compound, BPR3P0128. From a large-scale screening of a library of small compounds, BPR3P compounds were found to be potent inhibitors of influenza viral replication in Madin-Darby canine kidney (MDCK) cells. BPR3P0128 exhibited inhibitory activity against both influenza A and B viruses. The 50% inhibitory concentrations we...

Free radical generation is increasingly implicated in a variety of pathological processes, including drug toxicity. Recently, a number of studies have demonstrated the ability of gentamicin to facilitate the generation of radical species both in vivo and in vitro, which suggests that this process plays an important role in aminoglycoside-induced ototoxicity. Free radical scavengers are compound...

Using rat hippocampal slices, extracellularly recorded antidromic compound action potentials (cAP) were produced in CA1 pyramidal cell populations by electrical stimulation of the alveus at 0.5 Hz. These responses were additionally examined across a range of stimulus frequencies between 0.5 and 100 Hz. Anticonvulsant drugs in clinical use were applied via perfusion of the recording chamber. Thr...

In the experiments reported here, the amplitude and the latency of human compound action potentials (CAPs) evoked from a chirp stimulus are compared to those evoked from a traditional click stimulus. The chirp stimulus was created with a frequency sweep to compensate for basilar membrane traveling wave delay using the O-Chirp equations from Fobel and Dau [(2004). J. Acoust. Soc. Am. 116, 2213-2...

Dynorphin A (DYN)(l pM) decreased somatic calcium-dependent action potential (CAP) duration of a portion of dorsal root ganglion (DRG) neurons in a naloxone reversible manner. Responses to DYN differed from responses to Leu-enkephalin in that only DYN decreases of somatic CAP duration were associated with decreased action potential after hyperpolarization and persisted after intracellular injec...

INTRODUCTION The cardiac action potential (CAP) of stem cell-derived human cardiomyocytes (SC-hCMs) is potentially the most powerful preclinical biomarker for cardiac safety and efficacy in humans. Our experiments tested this hypothesis by examining the CAP and relevant pharmacology of these cells. METHODS The electrophysiological and pharmacological profiles of SC-hCMs were compared to rabbi...

BACKGROUND Different volumes of 0.9% NaCl may be used to reconstitute abobotulinumtoxinA yielding an injection volume that ranges from 0.05 to 0.1 mL per injection point for treatment of glabellar lines. OBJECTIVE To evaluate the efficacy, safety, and subject satisfaction of 2 different injection volumes to deliver the same unit dose of abobotulinumtoxinA for treatment of glabellar lines. M...
