Kerosene: A Study of Tissue Histology and Serum Vitamin and Heavy Metal Levels of Female Wistar Rats Chronically Exposed | Chapter 07 | Advances and Trends in Biotechnology and Genetics Vol. 2

Background: Kerosene a commonly available product used for a variety of purposes in many parts of Asia and Africa is sometimes sold in beverage bottles and jerry cans in both commercial and residential places due to inadequate number of filling stations. Therefore excessive exposure through both dermal and oral routes is common.

Objective: This study was embarked upon to ascertain the impact of trace amount of kerosene on tissue histology as well as serum vitamin and heavy metal levels in female Wistar rats.

Methods: Kerosene (0.4 mL/kg body weight) was administered to rats either through the oral or dermal route daily for a period of 30 days. The effects of kerosene administration on tissue histology; serum vitamin levels and serum concentrations of heavy metals were evaluated using hematoxylin- eosin staining technique; high performance liquid chromatography (HPLC); and atomic absorption spectrometry (AAS) respectively. Student’s t test and analysis of variance were used for statistical analysis of data. P <0.05 was considered significant.

Results: Histopathologic presentation such as pulmonary congestion, severely stunted villi, congestion of coronary vessels, and diffuse spongiosis of the cerebral cortex were observed in kerosene administered groups while control group featured no visible lesion. Results of heavy metals revealed that although As, Al and Cd were not significantly different in kerosene exposed groups compared with control, Si was significantly lower (oral), and significantly higer (dermal) compared with control. In addition, using analysis of variance (ANOVA) all estimated vitamins (except pantothenic acid) were significantly different in kerosene exposed groups compared with control.

Conclusion: The results of this study indicate that exposure to this product either through the oral or dermal route may be detrimental to health as it induced adverse alteration in vitamin and heavy metal levels as well as distorted tissue histo-architecture.

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 cells.

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 benefits,

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 be en
