Journal of Food and Drug Analysis

Overactivation of Wnt/β-catenin pathway due to dysfunction of retinoid-related orphan receptor α (RORα) is related to cancer development and progression. Diallyl disulfide (DADS), an active component of garlic, has been reported in our previous study for upregulation of RORα expression in gastric cancer (GC) cells. It remains to be elucidated the role and mechanism of RORα in DADS against GC. This study revealed that DADS treatment resulted in reduced expression levels of Wnt1, β-catenin, TCF-4, intranuclear β-catenin and p-β-catenin in GC cells, concomitant with the compromised expression of β-catenin target genes (Axin, c-Jun, and c-Myc). RORα overexpression augmented DADS-induced downregulation …

Journal of Food and Drug Analysis

Interleukin-1b (IL-1β) is a pro-inflammatory cytokine and its expression is increased in inflamed dental pulp. IL-1β affects plasminogen activation system molecules, which are crucial for tissue inflammation, fibrinolysis, matrix turnover, and cell adhesion and migration. Melatonin, which provides circadian and seasonal signals, is a physiological endocrine generated by the pineal gland. It has anti-oxidant and anti-inflammatory properties. Studies are warranted to determine whether melatonin prevents IL-1β-induced expression/production of plasminogen system molecules. Human dental pulp cells (HDPCs) were exposed to IL-1β or melatonin alone or to IL-1β with/without pretreatment with melatonin or other inhibitors. The mRNA expression of uPA, uPAR, and …

Journal of Food and Drug Analysis

Traditional Chinese medicine (TCM) has been applied to improve human health for millennia. In the TCM system, “medicinal property” (yao xing; hot and cold properties) is a core concept used to describe the influences of medicinal materials on human physiological conditions, and metabolites are believed to be one of the major ingredients of TCMs that affect their medicinal property. However, due to a lack of comprehensive analyses of TCM metabolomes, information about the relationships between TCM metabolite composition and medicinal property remains limited. In this pilot study, a mass spectral molecular networking-based platform was established and applied to …

Quantification Of Anthocyanosides In Grapes By Quechers And Biphenyl-Uhplc Tandem Mass Spectrometry, Lun-Chi Yang, Sung-Fang Chen

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 …

Metabolism-Involved Drug Interactions With Traditional Chinese Medicines In Cardiovascular Diseases, Ren-Jong Liang, Shu-Hao Hsu, Tien-Yu Chang, Tzu-Yi Chiang, Hong-Jaan Wang, Yune-Fang Ueng

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 …

Real-World Evidence Of The Herb-Drug Interactions, Hsueh-Yi Pan, Li-Wei Wu, Pin-Chun Wang, Ping-Hung Chiu, Meng-Ting Wang

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 …

Effects Of Sensory Cues On Product Acceptability And Consumer Perceptions, Emotions, And Behavior, Cristhiam Gurdian Curran

LSU Doctoral Dissertations

Visual and cognitive cues can affect overall liking (OL) and consumer perceptions, emotions, and behavior. The first study explored the effect of product color difference on the liking, perception, and purchase intent (PI) of cheese-flavored-tortilla chips (CFTC) formulations (A and B) on serving plates (plastic, foam, and paper). Color differences between formulations influenced crunchiness and saltiness liking and perception, which together with overall flavor liking and formulation, mainly determined CFTC OL. Although having similar fracturability (N) and sodium content, formulation A had higher crunchiness and saltiness likings. PI was influenced by crunchiness, saltiness, and OF liking with 37, 49, and …
