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.

A Brief Study of Middleware Technologies: Programming Applications and Management Systems | Chapter 15 | Novel Research Aspects in Mathematical and Computer Science Vol. 1

  Many platforms, services, applications, hardware, and operating systems are connected through the middleware layer. Because the middleware layer abstracts much low-level complexity and makes applications and software systems portable, it allows disparate systems to interface and function together in harmony. Middleware technologies enable software engineers to swiftly construct software systems and applications, allowing developers to focus on more important tasks. This chapter examines several types of middleware systems and discusses middleware capabilities, middleware operation, middleware's function in cloud-based systems, and the best middleware platforms to use. Middleware systems are widely utilised and can be found in practically any software system or application. Middleware programmes provide as a link between many sorts of systems and protocols. They serve as a mechanism for various systems. To successfully exchange information, it runs on a variety of operating system

A Prospective Study about Safety and Efficacy of Perioperative Lidocaine Infusion | Chapter 09 | New Horizons in Medicine and Medical Research Vol. 8

 Opioids cause clinically significant side effects such as respiratory depression, immunosuppression, muscle rigidity, negative inotropism, nausea, vomiting, hyperalgesia, urine retention, postoperative ileus, and drowsiness. Perioperative opioids are a major contributor to the United States' and other countries' opioid epidemics. Non-opioid analgesics, particularly lidocaine, are becoming more common for perioperative use as a result of this. A total of 185 adult patients were randomly assigned to one of two groups: control group I (105 patients) [fentanyl group] or group ii (80 patients) [opioid-free anaesthesia group]. Lidocaine 1.5 mg/kg bolus followed by 1.5 mg/kg/h infusion intraoperatively, and 1.5-2 mg/kg/h infusion for 2-8 hours postoperatively were given to patients in both groups at anaesthetic induction. Intraoperatively, both groups received analgesic adjuvants such as diclofenac 75 mg, paracetamol 1 gm, and mgso4 30-50 mg/kg. If the mean arterial pressure (map)

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili
