Journal of Food and Drug Analysis
In this study, the QuEChERS and UHPLC-MS/MS method using a biphenyl stationary phase was developed and applied for the rapid separation of 12 anthocyanosides in grapes. Efficient separation was achieved for a wide range of mono- and un-glycosylated anthocyanosides. The linear ranges of the target anthocyanosides were 0.5 to 500 ng mL−1. The intra- and inter-day precisions were both below 11.8%. Anthocyanosides in grapes from different sources were successfully quantified. Thus, the developed QuEChERS and UHPLC-MS/MS method provide an attractive alternative for the quantification of anthocyanosides in grapes.

Fluorescence Detection Of Malachite Green In Fish Based On Aptamer And Sybr Green I, Jia Wang, Chengyi Hong, Zhengzhong Lin, Zhi-Yong Huang
Journal of Food and Drug Analysis
A simple fluorescence method to quantitatively monitor malachite green (MG) was introduced based on the conformation switch effect of MG-aptamer (Apt) and the fluorochrome of SYBR Green I (SGI). SGI can embed in the stem–loop structure of Apt to produce fluorescence. However, the fluorescence will be quenched when MG is introduced because of the specific binding of Apt to MG. Under the optimal conditions, the fluorescence method displayed excellent linear relationship between the fluorescence quenching efficiencies and the MG concentrations ranging from 0.02 μmol L−1 to 1.0 μmol L−1. The detection limit of the method was 0.67 …

Bromelain, a cysteine protease found in pineapple, is known to exert protective effects against non-alcoholic fatty liver disease (NAFLD); however, the underlying mechanism is unclear. In this study, we aimed to investigate the molecular mechanisms underlying the beneficial effects of bromelain using in vivo and in vitro models. C57BL/6 mice were fed a high-fat diet (HFD) with or without bromelain (20 mg/kg/day) for 12 weeks. We found that treatment with bromelain alleviated hepatic lipid accumulation accompanied by the activation of AMP-activated protein kinase (AMPK) and autophagy flux, as evidenced by the elevated levels of phosphorylated AMPK, ATG5, ATG7, LC3-II, and …

Journal of Food and Drug Analysis
Herbal medicines have been widely used for the past millennia. Traditional Chinese medicine (TCM) is a major modality in Chinese medical care and has garnered global attention owing to its pharmacological effects and multi-targeted actions. The increased incidence of sequential or concurrent use of herbs and drugs in patients forces us to consider herb-drug interactions (HDIs) in this modern era. One of the main causes of HDIs is modulation of drug metabolism, in which cytochrome P450 (CYP), UDP-glucuronosyltransferase (UGT), and transporters play primary roles. In this review, we focus on in vivo studies of HDIs, particularly in the treatment of …

Journal of Food and Drug Analysis
Herbal medicine (HM) is a type of medicine that uses active ingredients made from plants to treat diseases and maintain health and wellbeing. Due to its increasing worldwide usage, the possibility of HMs and conventional drugs being concurrently used is high, potentially leading to adverse events resulting from herb-drug interactions. Despite the safety concerns regarding such interactions, few studies have been conducted for assessing clinical consequences of using HMs with conventional drugs in real-world settings. As clinical trials are not forthcoming rapidly enough to provide the evidence for herb-drug interactions, observational studies are considered as an alternative approach. The present …

Alzheimer’s disease (AD) is an age related neurodegenerative disease with pathology that includes amyloid plaques, neurofibrillary tangles and non-resolving neuroinflammation. Non-resolving neuroinflammation lasts the entire course of the disease and has deleterious effects and is often thought to accelerate AD pathology. Non-Steroidal Anti-inflammatory Drugs (NSAIDs) have commonly been used as therapeutics to treat pain, inflammation and vascular. NSAIDs work by altering the cyclooxygenase (COX) mediated biosynthesis of prostaglandins which are lipid mediators that have many physiological functions, for example nociception, inflammation and vasodilation. Epidemiological studies support the notion that NSAIDs could be used to treat AD. Yet, clinical trials using …

Chemical compounds that target dopamine (DA) D1 or D3 receptors have shown promise as potential interventions in animal models of cue-induced relapse. However, undesirable side effects or pharmacodynamic profiles have limited the advancement of new compounds in preclinical studies when administered as independent treatments. In this series of experiments, we explored the effects of co-administration of a D1-recepter partial agonist (SKF 77434) and a D3-receptor antagonist (NGB 2904) in heroin-seeking rats within a ‘conflict’ model of abstinence and cue-induced relapse. Rats were first trained to press a lever to self-administer heroin and drug delivery was paired contingently with cues (e.g., …

Pharmaceutical Sciences (PhD) Dissertations
Glucocorticoids (GCs) are steroid hormones that regulate diverse physiological processes. Synthetic versions of GCs are commonly used to treat inflammatory diseases such as asthma by modulating gene expression to suppressing several inflammatory activities. However, it is estimated that 5-10% of asthmatics are unresponsive to GCs, which may be explained by receptor desensitization and/or the presence of a neutrophilic endotype. One understudied phenomenon of GCs is their ability to induce rapid, non-genomic actions. For example, GCs can acutely modulate calcium concentrations levels, induce smooth muscle relaxation and modulate nitric oxide synthase activity, within minutes and sometimes seconds, which is too rapid …

Electronic Theses and Dissertations
Schizophrenia is a troubling and severe mental illness that is only incompletely treated by currently available drugs. New drug development is hindered by a scarcity of functionally relevant pharmacodynamic biomarkers that are translatable across preclinical and human subjects. Although psychosis is a major feature of schizophrenia, cognitive and negative symptoms determine the long-term functional outcomes for patients. Stimulus-evoked neural synchrony at gamma (~ 40 Hz) frequency plays an important role in the processing and integration of sensory information. Not surprisingly, schizophrenia patients show deficits in gamma oscillations. NMDA receptor (NMDAR) activation on fast-spiking parvalbumin-positive interneurons is deemed important for the …

Roles Of Oxidative Stress And Dna Methylation In Cigarette Smoking-Induced Accelerated Acute Myeloid Leukemia Progression, Mary Figueroa
Dissertations and Theses (Open Access)
Acute myeloid leukemia (AML) is a commonly diagnosed cancer in smokers. When current or former smokers have AML, they have worse survival compared to never smoking patients. This has been observed clinically for decades, but then it is unknown how smoking leads to worsened AML survival. Smoking causes oxidative stress and altered DNA methylation that persists for decades in peripheral blood mononuclear cells, but these changes from smoking have not been evaluated in the context of AML. We hypothesize that smoking-induced molecular changes, including altered DNA methylation associated with poor AML prognosis, promote AML. We developed a novel model to …
