Long-Term Monitoring of Arterial Blood Pressure and Pulse: Assessment of Influence of External Factors on Readings | Chapter 07 | Emerging Research in Medical Sciences Vol. 2

The research is based on long, regular observations of blood pressure and pulse - the heart rate (more than 18 years). The values of these readings are taken from the diary of self-control, which is kept by a patient, one of the authors of this publication, a man born in 1940. Such effective control over the patient's condition, implemented in our case, ensuring its normal vital activity, makes it possible to investigate the influence of external factors on the hemodynamics of the body and the manifestation of the marked temporal characteristics.

A difference between the morning and evening series was noted. The characteristics of evening monitoring readings are more balanced. Spectral analysis allows for a more detailed analysis and comparison of the data. Seven-day component is clearly seen in evening series being modulated with three-year period for the pulse. The morning series are characterized by a “lunar” component with the ~27.35-day period. The absence of a weekly period in the morning readings indicates a rapid (moment of sleep) relaxation of the body from the rhythmic stress of the past day. The manifestation of the "lunar" response can be associated with an increased sensitivity of the body during and after the sleep.

The analysis of pulsatile blood pressure, i.e. the difference between SBP and DBP, provides for more options for assessing the state of the body. Correlation relationship between morning and evening data are also attracted. A comparison with the results are performed, the relationship with the Wolf numbers is discussed.

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...

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...

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...
