Abstract
Sickle cell disease (SCD) treatment and management remain a challenging puzzle especially among developing Nations. Chrysin's sickling-suppressive properties in human sickle (SS) erythrocytes in addition to its effect on AA-genotype erythrocytes were evaluated. Sickling was induced (76%) with 2% sodium metabisulphite at 3 h. Chrysin prevented (81.19%) the sickling and reversed same (84.63%) with strong IC50s (0.0257 µM and 0.00275 µM, respectively). The levels of oxygenated haemoglobin in the two groups (before and after induction approaches) were similar but significantly (P < 0.05) higher than that of SS erythrocytes (the 'induced' control), with chrysin-treated AA-genotype showing no effects relative to the untreated. The level of deoxygenated haemoglobin in the 'induced' control group was significantly (P < 0.05) higher than those of the chrysin-treated SS erythrocytes. Normal and chrysin-untreated erythrocytes (AA-untreated) were significantly more resistant to osmotic fragility than the SS-untreated. However, treatment with chrysin significantly reduced the osmotic fragility of the cells relative to the untreated cells. Furthermore, chrysin treatment significantly lowers the high level of 2,3-diphosphoglycerate (2,3-DPG) observed in the sickle erythrocytes, with no effects on AA-genotype erythrocytes. Based on functional chemistry, chrysin treatment alters the functional groups in favour of its antisickling effects judging from the observed bends and shifts. From metabolomics analysis, it was observed that chrysin treatment favors fatty acid alkyl monoesters (FAMEs) production with concomitant shutting down-effects on selenocompound metabolism. Thus, sickling-suppressive effects of chrysin could potentially be associated with modulation of oxygenated and deoxygenated haemoglobin via alteration of human sickle erythrocyte's functional chemistry and metabolic pathways implicated in SCD crisis.

Abstract
Women with a history of pre-eclampsia (PE) tend to have a higher risk of developing cardiovascular and neurological diseases later in life. Imbalance in oxidative markers and purinergic enzymes have been implicated in the pathogenesis of neurological disease. This study investigated the effect of PE on oxidative imbalance, purinergic enzyme inhibitory activity, acetylcholinesterase and chymotrypsin activities in the brain of PE rat model at post-partum/post-natal day (PP/PND) 60. Pregnant rats divided into early-onset and late-onset groups were administered with Nω-nitro-l-arginine methyl through drinking water at gestational days 8-17. Rats were allowed free access to water throughout the pregnancy and allowed to deliver on their own. The mother and the pups were euthanized at PP and PND 60, respectively, the cortex and the cerebellum excised, homogenized and stored for analyses of the enzymes. Results showed an increase in nitric oxide and malondialdehyde with a concomitant decrease in reduced glutathione and superoxide dismutase, an indication of oxidative damage. Also, there was an increase in acetylcholinesterase activity with a decrease in chymotrypsin, adenylpyrophosphatase and ecto-nucleoside triphosphate diphosphohydrolase activities in both the cortex and the cerebellum of the mother and the pups at PND 60. These results indicate the involvement of oxidative stress, increased cholinergic activity and depleted proteolytic and purinergic activities in PE-induced neurotoxicity.

Abstract
The antioxidative effect of Monodora myristica seed acetone extract and its effect on chemical functional groups were investigated in sickled erythrocytes as well as molecular modeling of the antisickling potentials of its secondary metabolites. The extract was subjected to gas chromatography–mass spectrometry to identify the compounds present, which were then docked into the allosteric-binding site of deoxy-hemoglobin. The extract was incubated with sickled erythrocytes at 37°C for 6, 12, and 24 h and were subjected to antioxidative analysis for reduced glutathione (GSH), superoxide dismutase (SOD), catalase, and lipid peroxidation (LPO). Chemical functional group of the treated cells was analyzed via Fourier transform infrared spectroscopy (FTIR). The predominant compounds identified were 17-octadecynoic acid; oleic acid, androstan-3-one, 17-hydroxy-2-methyl- (2.beta.,5.beta.,17.beta.)-; estran-3-one, 17-(acetyloxy)-2-methyl-, (2.alpha., 5.alpha., 17.beta.), and (+)-3-carene, 10-(acetylmethyl)-. They all fitted well within the active site of Hb with good binding affinity, as evidenced by the negative CDocker interaction energies of their complexes ranging between −54.4 and −26.7 kcal/mol. Treatment with the extract exacerbated SOD and catalase activities as well as GSH level, while LPO was suppressed. This antioxidative activity was time and/or dose dependent, with 6 and 12 h incubation showing the optimum activity. FTIR analysis of the treated cells showed the presence of hydrophobic functional groups. The synergetic molecular interaction of the major compounds of the extract with the α-dimer of Hb depicts an antisickling effect of M. myristica acetone extract. This is accompanied by exacerbation of endogenous antioxidant enzymes activity and modification of the functional chemistry of the cells.

Abstract
This study was designed to investigate the alteration of redox status by commonly used antimalarials in Nigeria. Drugs used were artemisinin, artesunate, chloroquine, coartem and quinine at the final concentrations of 0.5–8.0 mg/mL. Blood samples were collected from malarial patients and apparently healthy humans for comparison. Reduced glutathione, catalase, superoxide dismutase (SOD) activities, protein content and lipid peroxidation were determined. All drugs significantly ( p < 0.05) increases the protein level relative to control in normal blood, whereas in the infected, a significant ( p < 0.05) reduction was observed. In normal blood, the antimalarials dose dependently decreased ( p < 0.05) SOD and catalase activities with significant ( p < 0.05) increase in the infected. The level of glutathione in normal blood significantly ( p < 0.05) increases as compared with control, whereas in the infected, similar observation was made except that the levels were less, relative to control sample. Malondialdehyde level significantly ( p < 0.05) increases with increase in drugs concentration even though less than the level in the control with few exceptions. These effects were dose dependent and more pronounced in non-malarial conditions. Commonly used antimalarials might alter the redox status in both healthy and non-healthy subjects thereby inducing oxidative stress.
