Instrumental Analysis of Foods: Inductively Coupled Plasma Mass Spectrometry for Determination of Metals in Cereals and Fast Ion Chromatography Analysis for Minerals in Aqueous Sport Drinks | Chapter 10 | Advances in Applied Science and Technology Vol. 5

Aims: Foods  are  analyzed  for  their  content  for  important  reasons  that  include:  Adherence  to government  regulations,  nutritional  labeling,  authentication,  inspection  (for  grading),  safety,  quality control and detection of adulterants.

Study  Design: Inductively  coupled  plasma  mass  spectrometry  (ICP-MS)  analysis  of  various commercial  cereals  was  accomplished.  Commercial  drinks  were  analyzed  by  ion  chromatography instruments.

Place  and Duration  of  Study: The  investigation  was  carried  out  at  the  University  of  Nebraska, Omaha Nebraska from January 2014 to May 2014.

Methodology: Cereals were treated in strong acid to extract heavy metals. Following dilution steps, these  extracts  were  injected  into  ICP-MS  for  analysis. Quantity  of  metals  as  well  as  isotope distribution was established. Commercial sports drinks were examined for clarification and injected into  ion  chromatography  instruments  for  analysis  for  calcium,  sodium,  potassium,  magnesium, chloride, phosphate, sulphate and fluoride.

Results: (ICP-MS) analysis of  various  commercial  cereals showed  a  content  of  chromium,  nickel, copper, zinc and traces of lead. In general, zinc was found to be highest in content within the cereal products  analyzed  ranging  from  2.951 mg/kilogram  to  90.56 mg/kilogram  (mean  =  58.38 mg/kilogram),  followed  by  copper  ranging  from  1.218 mg/kilogram  to  4.395 mg/kilogram  (mean  = 2.756 mg/kilogram). This is followed in amounts (by average of all samples tested) by nickel, lead and chromium. Chromium, copper, nickel and zinc are considered human micronutrients. Sport drinks are consumed for their mineral content and enhancement of electrolytes. Various sports drinks analyzed showed both cation and anion minerals in their content, which included: sodium, potassium, calcium, magnesium, sulfate, phosphate, chloride, fluoride and nitrate ions.

Conclusion: ICP-MS and ion chromatography are versatile approaches for analysis of food nutrient value and metals content. ICP-MS can track the absorption of heavy metals into commercial cereals. Ion  chromatography  can  identify  adulterants  in  sport  drinks. Current  ion  chromatography instrumentation can quickly and with versatility assay a broad concentration of cations and anions in electrolyte mixtures. The monitoring of electrolyte contentis an important aspect for the clinical use of such  mixtures  for  the  treatment  of  disease.  Sensitive  and  versatile  methodologies  for  monitoring nutrients inside food products will enhance their safety, government compliance, nutritional value and the demands from consumers.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Risk Factors for Postpartum Psychiatric Disorders. A Review of the Literature | Chapter 8 | New Visions in Medicine and Medical Science Vol. 4

  Objective: The aim of this study was to explore the risk factors for the development of postpartum psychiatric disorders through international literature. Materials and Methods: Throughout many articles in PubMed, Google scholar and PsycInfo, a great amount of recent data was gathered to identify the disorders that are most common as well as their risk factors. Results: After childbirth, most commonly women experience postpartum depression, anxiety disorders, post-traumatic stress disorder and postpartum psychosis. All the disorders have many similar risk-factors with the main one being preexisting psychiatric disorder and many similar symptoms too. Conclusions: Women after childbirth are at risk of experience many psychiatric disorders, such as postpartum distress, postpartum post traumatic stress disorder and even more rarely postpartum psychosis. It is important to provide comprehensive support to ensure the well-being of both the mother and the infant and this will b...

Alkali Element Modification of Glucose Molecules as a Method to Dissolve Cancer Cells | Chapter 12 | New Visions in Medicine and Medical Science Vol. 4

  The present study highlights about alkali element modification of glucose molecules as a method to dissolve cancer cells. The central regulation of the mechanisms governing cell proliferation has little effect on cancer cells. Cancer cells are entirely independent of the central command and divide and proliferate on their own, making it challenging to activate their response mechanism. Precisely, this is the reason why they are at risk to the health of humans and/or any biological entities. Instead of trying to reconnect the central command of the growth control mechanism to cancer cells that are already out of the range, we present a method of using the cancer cell’s own irresponsive and uncontrolled growth mechanism to their disadvantage and destroy the cancer cells. We found that this is achievable in an atomic/molecular level study of the glucose molecule, which is the primary food source used for growth and energy generation by all cells in the body, including the cancer cel...
