Immunity and Sex Concerns on Behaviour From IgE vs IgG to sex conditioned socialization? | Chapter 10 | Modern Advances in Pharmaceutical Research Vol. 1

Aims: To find evidence that the immune response modifies behavior by regulating sex hormones.
Study Design: Experimental transversal case control study and longitudinal experimental case control study.
Place and Duration of Study: Biochemistry and Molecular Biology Chair, School of Medicine, Medical Sciences Faculty, National University of Córdoba. 2009-2015.
Methodology: Albino Swiss mice Rockefeller strain (110) weighing 30g were assigned to two experimental designs. Transversal case control physiologic solution vs or Celtis tala pollen glycoprotein T or Bovine serum albumin A evaluated in forced swimming test along the course of antibodies production. Similar study but cases were treated with spironolactone (S) and immunized as previous mice. Longitudinal case control study with cases and controls the same categories as the second study but followed and evaluated in FST. Climbing, swimming floating summing a total of 8 events and delated time to contact another mouse (CT) were recorded (seconds). Plasma IgE, IgG and testosterone (Tt) were also measured.
Results: Immunization with T increases the proportion of climbing in both sexes at day 7(C male 0.42, T male 0.72, C female 0.28, T female 0.68) and reverted at day 15 (C male 0.8, T male 0.35, C female 0.47, T female 0.43), while A increased swimming in both sexes. Since climbing is more frequent in male we treated mice with S to determine if immunization effects were mediated by testosterone and reverted the changes triggered by C. tala (day 7, ST. males 0.22, ST females 0.35, day 15 ST. male 0.23, ST. female 0.32). T caused a shortening of CT in males from day 7 to 15, S produced the opposite and ST was partly similar to T (T.male12.5 to 5, S male 8,2 to 14, ST male 11 to 4.2 in sec, T female 2.9 to 6.2, S female 7.8 to 17, ST female 13 to 9.6 sec). SA in males enhanced swimming  and  decreased  floating  while  in  female decreased  swimming  and  increased  floating.  Plasma concentration ranges of Tt (ng/mL) were: CM 0.75-6.72, TM 31.1-58.5; STM 26-29.5; females remained between 0.3-039, AM 0.75-9, AF 1-19, SAM 26.5-29, SAF 0.9-1.2.
Conclusion: The results presented in this paper support our hypothesis that immune response could modify mice FST performance and socialization post stress by regulation of testosterone levels.

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...
