Vitamin D Receptor Gene Polymorphisms with Acute Lower Respiratory Infections | Chapter 7 | New Visions in Medicine and Medical Science Vol. 4

 Acute Lower Respiratory Infections (ALRI) is the leading cause of death in children worldwide, particularly in underdeveloped nations where the incidence is over 10 times greater in children who have an age younger than 5 years old. Multiple in vitro studies have demonstrated the function of vitamin D in facilitating and controlling immune response by interacting with the vitamin D receptor (VDR). The objective of this study was to determine the correlation between vitamin D receptor polymorphism and ALRI.

Methods: The study examined three vitamin D receptor (VDR) polymorphisms (FokI, TaqI, ApaI) using the PCR-RFLP technique in 78 hospital cases of acute lower respiratory infections (ALRI). These patients were then compared to 75 age and sex matched apparently healthy children below the age of five. Additionally, serum levels of vitamin D were assessed.

Results: The presence of the TaqI tt genotype and the independent t allele were demonstrated to provide a substantial protection against ALRI. The genotypes of FokI and ApaI did not show any significant correlation with the risk of Acute Lower Respiratory Infection (ALRI). Children with ALRI exhibited very low levels of vitamin D. The study did not find any statistically significant variation in vitamin D levels across the three genotypes in FokI, TaqI, and ApaI polymorphisms.

Conclusion: This study shows that individuals with the tt genotype have a notable defense against bacterial-induced ALRI.

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...

There is No Standard Model of ZFC and ZFC2 | Chapter 03 | Advances in Mathematics and Computer Science Vol. 1

In this Chapter we obtain a contradictions in formal set theories under assumption that these theories have omega-models or nonstandard model with standard part. An possible generalization of Lob’s theorem is considered. Main results are: (i) ¬Con(ZF C+ ∃ M ZFC st ), (ii) ¬Con(N F+ ∃ M NF st ), (iii) ¬Con(ZF C 2 ), (iv) let k be an inaccessible cardinal then ¬Con(ZF C+ ∃ κ), (v) ¬Con(ZF C+ (V=L)), (vi) ¬Con(ZF+ (V=L)).

Study on Processing Method Influences the Effect of Cassava (Manihot esculenta) Consumption on Blood Lipid Profile in Rats | Chapter 8 | Current Research and Development in Chemistry Vol.1

Cassava is consumed in many tropical countries and is fast becoming the major raw material of many diets, especially in the bakery, brewery and pharmaceutical industries. In a study to determine the effects of various formulations of Cassava feeds on blood lipid profile in rats. Forty adult Wistar rats weighing between 120 and 150 g were divided into 4 groups of 10 rats each. The rats were acclimatized for one week; fed with different formulations of Cassava feeds adlibitum, after which the rats were allotted into groups. Group 1 was fed on Garri; group 2 on Cassava flour; group 3 on Tapioca, and the control group (group 4) on normal chow. After 4 weeks, each animal was anaesthetized by exposure to chloroform vapour and blood samples collected by cardiac puncture. Group 1 diet (Garri) significantly increased HDL-cholesterol (HDL-C) concentration and significantly decreased LDL-cholesterol (LDL-C) concentration (p<0.05) compared with the control group. In Group 2 (Cassava flour), t...
