Superweeds And Suspect Seeds: Does The Genetically-Engineered Crop Deregulation Process Put American Agriculture At Risk, Margaret Sova Mccabe

Law Faculty Scholarship

The federal government’s regulatory approach to genetically engineered (GE) crops, known as “The Framework”, is now twenty-five years old. Despite two and half decades of a consistent regulatory regime, GE crop and food regulation remains controversial. This article suggests that regulatory science and its tenets of independence, transparency, and public science should guide reforms of The Framework so that it is an efficient and reliable regulatory system. The article has four parts: 1) it provides a brief overview of the history of GE crop regulation; 2)it describes the key attributes of The Framework and related regulatory documents, with particular focus …

Recent Advances In The Application Of Non Thermal Methods For The Prevention Of Salmonella In Foods, Shilpi Gupta, Nissreen Abu-Ghannam

Books/Book Chapters/ Proceedings

Food-borne illness as a result of consumption of foods contaminated with pathogenic bacteria is a world-wide concern. The presence and subsequent growth of micro-organisms in food in addition to improper storage not only results in spoilage but also in a reduction of food quality. The microbiological safety in ready to eat products is a cause of big concern not only for the consumers and food industries but also for the regulatory agencies. The number of documented outbreaks of foodborne diseases has increased in the last decade with Salmonella spp., Listeria monocytogenes and Escherichia coli being responsible for the largest number …

Uracil Accumulation In Folate Depleted Mouse Embryonic Fibroblasts, Eneida Doko

Wayne State University Theses

Folate is a water-soluble vitamin B that plays a critical co-enzyme in the de novo nucleotide synthesis and other biochemical processes including DNA metabolism, DNA repair, DNA methylation, and cellular growth. Folate deficiency has been associated to increase the risk of neural tube defects (NTDs) and cancers of the lung, breast, colon, cervix, esposphagus and brain. Most importantly, folate deficiency has been shown to increase uracil misincorporation into DNA and therefore induce DNA damage repaired by the base excision repair (BER) pathway. In response to folate depletion, levels of thmidylate decrease in the deoxyribonucelotide pool, resulting in uracil being misincorporation …

The Effects Of Oil Palm Phenolics On Inflammation And Oxidative Stress In Relation To Amyloid Beta Plaques In Fad-Mutant And Wild Type B103 Cells, Lindsay Michelle Godsey

Wayne State University Theses

Alzheimer's disease (AD) affects approximately 35.6 million people in the world today (35). It is expected that by year 2050, an individual will develop AD every 33 seconds (8). Unfortunately, the etiology is not well known. Familial Alzheimer's disease (FAD) occurs due to specific genetic mutations, making it possible to replicate them in cells. Using B103 rat neuroblastoma cells transfected with a cDNA construct, wild type cells and FAD mutant cells were used in this research.

Natural ingredients such as oil palm phenolics (OPP) contain antioxidants. After finding the optimal experimental parameters, OPP was found to aid in the destabilization …

Effect Of Different Rehydration Temperatures On The Moisture And Phytochemical Constituents Of Dried Edible Irish Brown Seaweed., Sabrina Cox, Shilpi Gupta, Nissreen Abu-Ghannam

Articles

The effect of temperature (20, 40, 60, 80 and 100 °C) on the rehydration kinetics and phytochemical constituents of dried edible Irish brown seaweed, Himanthalia elongata, were studied. The moisture content of fresh and dried seaweed was 4.07 and 0.07 g water/g dry basis, representing a 98.1% reduction in water content. All rehydration moisture curves had a clear exponential tendency, and it was observed that the rehydration time decreased when temperature was increased. Although restoration of the product to its original moisture content was achieved, rehydration resulted in losses in phytochemical content. Moisture equilibrium was achieved fastest at 100 °C …

Articles

The aim of this study was to investigate the effect of delactosed whey permeate (DWP) 27 treatment on antioxidant and physico-chemical properties of strawberries. Fresh strawberries 28 treated with 3 % DWP were analyzed for different quality, nutritional and microbiological 29 markers during 10 days of storage at 5 °C. The results showed that DWP treatment 30 significantly reduced incidences of decay (70 %) and numbers of total aerobic counts (~1.4 31 Log10 CFU/g) and yeast and moulds (~1.8 Log10 CFU/g). DWP treatment also inhibited the 32 loss of firmness (15 %) and maintained significantly (p

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh

Articles

Thermoduric gram-positive bacteria are indigenous in milk, cheese, whey and other dairy products. They are capable of surviving heat processes and can result in quality defects and a shortened product shelf life. In Ireland, premium products such as whey protein concentrate (WPC) are often adversely affected by these microorganisms, particularly during the winter months.A high bacterial count in the WPC can result in the product being sold at a lower grade, with an overall loss of revenue for the manufacturer. This study recovered thermoduric bacterial isolates (n = 140) from an Irish WPC process during the months of November–February.Using molecular …

Synthesis, Characterisation And Photo-Stability Of A Folate-Modified Β-Cyclodextrin As A Functional Food Additive., Zlata Tofzikovskaya, Christine O'Connor, Mary Mcnamara

Articles

A novel two-step synthetic route was developed and gave the mono-substituted derivative 6-deoxy-6-[(1-(2-amino)ethylamino)folate]-b-cyclodextrin (CDEnFA) with high yield (60 %). Elemental analysis, mass spectrometry, ¹H and ¹³C NMR, FTIR and Raman spectroscopies demonstrated the successful synthesis of the γ isomer only with no evidence of the presence of other isomers or free folic acid. Electronic absorption spectroscopy was used to study the photochemical properties of CDEnFA and showed that in both the solid state and aqueous solution CDEnFA is considerably more photo-stable than free folic acid.

In addition AP is also a good source of phytochemicals such as phenolic acids and flavonoids making AP a valuable source of antioxidants. The common applications of this by-product are the direct disposal to soil in a landfill and for pectin recovery usage. These applications are not sufficient to drain the several tonnes produced every year and studies to valorise the AP for other purposes have gained momentum. AP due to its chemical composition, rich …

Probability Of Identification: A Statistical Model For The Validation Of Qualitative Botanical Identification Methods, Robert A. Labudde, James M. Harnly

Mathematics & Statistics Faculty Publications

A qualitative botanical identification method (BIM) is an analytical procedure that returns a binary result (1 = Identified, 0 = Not Identified). A BIM may be used by a buyer, manufacturer, or regulator to determine whether a botanical material being tested is the same as the target (desired) material, or whether it contains excessive nontarget (undesirable) material. The report describes the development and validation of studies for a BIM based on the proportion of replicates identified, or probability of identification (POI), as the basic observed statistic. The statistical procedures proposed for data analysis follow closely those of the probability of …

Coupled Electromagnetic And Heat Transfer Model For Microwave Heating In Domestic Ovens, Krishnamoorthy Pitchai, Sohan Birla, Jeyamkondan Subbiah, D. D. Jones, Harshanardhan Thippareddi

Department of Food Science and Technology: Faculty Publications

Microwave ovens are used extensively for heating a variety of not-ready-to-eat food products. Non-uniform heating of foods in microwave ovens is a major concern in assuring microbiological safety of such products. The non-uniform heating of foods is attributed by complex interaction of microwaves with foods. To understand this complex interaction, a comprehensive model was developed to solve coupled electromagnetic and heat transfer equations using finite-difference time-domain based commercial software. The simulation parameters, cell size, heating time step, and number of iterations for steady state electromagnetic field were optimized. The model was validated by 30 s heating profile of a cylindrical …
