Food Science Faculty Articles and Research

Many elasmobranch (shark and ray) species are considered threatened and their identification in processed products is important for conservation and authentication purposes. However, identification of elasmobranch species in shark cartilage pills has proven difficult using existing methodologies. The objective of this study was to develop a DNA mini-barcoding protocol using a ~130 bp region of the cytochrome c oxidase subunit I (COI) gene for species identification in shark cartilage pills. A total of 22 shark cartilage products underwent DNA extraction in duplicate using the DNeasy Blood and Tissue Kit (Qiagen). The effectiveness of a clean-up step following DNA extraction was …

The Conjoint Effect Of Front-Label Claims’ Surface Size And Distance-To-Center On Customers’ Visual Attention And Emotional Response, Ana Isabel Rodríguez-Escudero, Pilar Carbonell, Pablo Moreno-Albaladejo

Journal of Applied Packaging Research

The research purpose is to develop a better understanding on how two claim characteristics, surface size and distance-to-center, affect customers’ attention and emotional responses.The study is based on information obtained from 42 shoppers from a retail chain in Great Britain. Visual attention is measured using an eye-tracking methodology and customers’ emotions by electrodermal activity (EDA), a common indicator of autonomic nervous system (ANS). Our research reveals that, for claims located close to the center of the label, increases in surface size compensate for the attention loss associated with moving the claim further off the center. However, for peripheral product claims, …

Imatinib Mesylate Effects On Zebrafish Reproductive Success: Gonadal Development, Gamete Quality, Fertility, Embryo-Larvae Viability And Development, And Related Genes, Nader Ahmadi, Seyed-Mohammadreza Samaee, Robert A. Yokel, Aliasghar Tehrani

Pharmaceutical Sciences Faculty Publications

Imatinib (IM) is a tyrosine kinase (TK) inhibitor (TKI) used to treat chronic myeloid leukemia. Clinical case reports and a few laboratory mammal studies provide inconclusive evidence about its deleterious effects on reproduction. The aim of the current study was to evaluate the potential of zebrafish to characterize IM-induced effects on reproduction and clarify IM effects on reproductive success. To this end, we exposed adult zebrafish to four concentrations of IM for 30 days followed by a 30-day depuration period. IM exposure caused a concentration-dependent, irreversible, suppression of folliculogenesis, reversible decrease in sperm density and motility, decreased fecundity and fertility, …

Seaweeds As Nutraceuticals For Health And Nutrition, Emer Shannon, Nissreen Abu-Ghannam

Articles

Throughout human history, seaweeds have been used as food, folk remedies, dyes, and as mineral-rich fertilisers. Seaweeds as nutraceuticals or functional foods with dietary benefits beyond their fundamental macronutrient content are now a major research and industrial development concept. The occurrence of dietary and lifestyle related diseases, notably type 2 diabetes, obesity, cancer, and metabolic syndrome has become a health epidemic in developed countries. Global epidemiological studies have shown that countries where seaweed is consumed on a regular basis have significantly fewer instances of obesity and dietary-related disease. This review outlines recent developments in seaweed applications for human health from …

Bioinformatics Identification Of Anti-Crispr Loci By Using Homology, Guilt-By-Association, And Crispr Self-Targeting Spacer Approaches, Yanbin Yin, Bowen Yang, Sarah Entwistle

Department of Food Science and Technology: Faculty Publications

Anti-CRISPR (Acr) loci/operons encode Acr proteins and Acr-associated (Aca) proteins. Forty-five Acr families have been experimentally characterized inhibiting seven subtypes of CRISPR-Cas systems. We have developed a bioinformatics pipeline to identify genomic loci containing Acr homologs and/or Aca homologs by combining three computational approaches: homology, guilt-by-association, and self-targeting spacers. Homology search found thousands of Acr homologs in bacterial and viral genomes, but most are homologous to AcrIIA7 and AcrIIA9. Investigating the gene neighborhood of these Acr homologs revealed that only a small percentage (23.0% in bacteria and 8.2% in viruses) of them have neighboring Aca homologs and thus form Acr-Aca …

Application Of Active And Edible Films Of Sodium Caseinate To Extend The Shelf-Life Of Argentine Pategrás Cheese, Brenda S. Álvarez, Natalia Damiani, Marina Czerner, Josefa F. Martucci, Liesel B. Gende

Journal of Applied Packaging Research

Argentine Pategrás cheese is one of the most popular types of cheese in Argentina. The main spoilage causes in these products are microbiological contamination and lipid rancidity. Semi-hard cheeses are usually covered with a paraffin wax that favors its preservation. When pieces are stored, cutting faces must be protected to prevent desiccation and contamination. Active biodegradable films are an alternative to the traditional materials, in particular, casein-based edible films are attractive for food applications. In the present work, active films of sodium caseinate with oregano (Origanum vulgare) and laurel (Laurus nobilis) essential oils were produced for …

Anti-Cancer Effects Of Oleocanthal And Extra Virgin Olive Oil, Limor Goren

Dissertations, Theses, and Capstone Projects

Oleocanthal is a phenolic compound found in varying concentrations in extra virgin olive oil. Oleocanthal has been shown to be active physiologically, benefiting several diseased states by conferring anti-inflammatory and neuroprotective benefits. Recently, we and other groups have demonstrated its specific and selective toxicity toward cancer cells; however, the mechanism leading to cancer cell death is still disputed. The current study demonstrates that oleocanthal induced damage to cancer cells’ lysosomes leading to cellular toxicity in vitro. Non-cancer cells were significantly less affected. Lysosomal membrane permeabilization following oleocanthal treatment in various cell lines was assayed via three complementary methods. Additionally, …
