A Recent Study on the Synthesis and DFT Collaborated Experimental Characterization of Some Pyrazolone Functionalized Dioxovanadium(V) Schiff Base Complexes | Chapter 4 | Current Perspectives on Chemical Sciences Vol. 10

 The goal of this paper is to synthesise and characterise dioxovanadium(V) complexes of semicarbazone ONO-donor ligands, LH [where LH = N-(4'-benzoylidene-3'-methyl-1'-phenyl-2'-pyrazolin-5'-one)-semicarbazone (bmphp-semH), N-(4'-butylidene-3'-methyl By oxidising bis(acetylacetonato) oxovanadium(IV) complexes of the above ligands with ambient oxygen (bubbling air) for 2-3 days, they were generated from ethanol-methanol mixed solvent (1/10) solutions of bis(acetylacetonato) oxovanadium(IV) complexes of the aforementioned ligands. Physiochemical analyses, such as percentages of different elements, magnetic susceptibility, conductance, FT-IR, UV-Visible, and mass spectrometry, were used to corroborate the composition and formulas of complexes. At the convergence of DFT and experimental formulation interface, one of the typical complexes, cis-[VO2(bmphp-sem)(H2O)], was examined. To approximate geometry optimization, charge distribution, and molecular orbital descriptions, typical B3LYP/LANL2DZ combinations were employed. Absolute electronegativity (Xabs) and absolute hardness (η) are two global reactivity parameters that have been used. Overall, the compounds had a cis-octahedral structure, according to the research.

Haematological Parameters of Japanese Quail (Coturnix coturnix japonica) Experimentally Infected with Salmonella enterica Serovar Gallinarum | Chapter 4 | Current Research Trends in Biological Science Vol. 3

Aim: Toevaluate some haematological changes in Japanese quails (Coturnix coturnix japonica)
experimentally infected with
Salmonella enterica serovar Gallinarum.
Methodology: A total of 160 (108 males and 52 females) Japanese quails (Coturnix coturnix
japonica
) were used in this study. The quails were obtained at the age of four weeks from the Poultry
Division of the National Veterinary Research Institute, Vom, Plateau State, Nigeria. They were
randomly selected and assigned into four groups (A, B, C and D) of forty quails each. Groups A, B
and C were infected with
Salmonella enterica serovar Gallinarum per os at the dose of 106, 104 and
10
2, respectively, while group D served as the control. Blood with anticoagulant (ethylenediamine
tetra-acetic acid) was used for the determination of haematological parameters.
Results: There were no significant differences in haematological parameters (P > 0.05) between the
groups before infection. There were, however, significant changes (P<0.05) in haematological
parameters such asred blood cells (RBC), haemoglobin (Hb) concencentrations, packed cell volume
(PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular
haemoglobin concentration (MCHC), heterophil and lymphocyte counts between the infected groups
when compared with the control group. There were also significant changes (P<0.05) in these
haematological parameters post-infection compared to before infection within each infected group.
Conclusion: This study has shown that Salmonella gallinarum causes decrease in some
haematological parameters, such as packed cell volume (10%) and red blood cell count (10%) and
haemoglobin concentration (5%) and increase in heamatological indices, such as mean corpuscular
volume (5%), mean corpuscular haemoglobin (30%), and mean corpuscular haemoglobin
concentration (30%) above control group values in Japanese quails (
Coturnix coturnix japonica).
These findings could be useful in the diagnosis of subclinical cases of fowl typhoid in the Japanese
quails and other birds.
