    The global burden of malaria seems unabated. Africa carries the greatest burden accounting for over 95% of the annual cases of malaria. For the vision of a world free of malaria by Global Technical Strategy to be achieved, Africa must take up the stakeholder’s role. It is therefore imperative that Africa rises up to the challenge of malaria and champion the fight against it. The fight against malaria may just be a futile or mere academic venture if Africans are not directly and fully involved. This work reviews the roles playable by Africans in order to curb the malaria in Africa and the world at large

    From Wiley via Jisc Publications RouterHistory: received 2022-12-25, rev-recd 2023-01-07, accepted 2023-02-06, pub-electronic 2023-02-18Article version: VoRPublication status: PublishedThis study demonstrated the therapeutic potentials of Cucumeropsis mannii seed oil (CMSO) capable of alleviating BPA‐induced dyslipidemia and adipokine dysfunction. In this study, we evaluated the effects of CMSO on adipokine dysfunctions and dyslipidemia in bisphenol‐A (BPA)‐induced male Wistar rats. Six‐week‐old 36 albino rats of 100–200 g weight were assigned randomly to six groups, which received varied doses of BPA and/or CMSO. The administration of BPA and CMSO was done at the same time for 42 days by oral intubation. The adipokine levels and lipid profile were measured in adipose tissue and plasma using standard methods. BPA induced significant (p < .05) increases in triglycerides, cholesterol, leptin, LDL‐C, and atherogenic and coronary risk indices in adipose tissue and plasma, as well as a decrease in adiponectin and HDL‐C levels in Group II animals. BPA administration significantly (p < .05) elevated Leptin levels and reduced adiponectin levels. BPA plus CMSO reduced triglycerides, cholesterol, leptin, LDL‐C, and atherogenic and coronary risk indices while increasing adiponectin levels and HDL‐C in adipose tissue and plasma (p < .05). The results showed that BPA exposure increased adipose tissue as well as serum levels of the atherogenic index, triglycerides, cholesterol, coronary risk index, LDL‐C, leptin, and body weight with decreased adiponectin levels and HDL‐C. Treatment with CMSO reduced the toxicities caused by BPA in rats by modulating the body weight, adiponectin/leptin levels, and lipid profiles in serum and adipose tissue. This study has shown that CMSO ameliorates BPA‐induced dyslipidemia and adipokine dysfunctions. We suggest for further clinical trial to establish the clinical applications

    Abstract Introduction This study was motivated by the increasing global incidence of benign prostatic hyperplasia (BPH) and the promising potential of nutraceuticals as complementary therapies in ameliorating its burden. We report the safety profile of C. esculenta tuber extracts, a novel nutraceutical in benign prostate hyperplasia in a rat model. Methods In this study, forty-five male albino rats were randomly assigned to 9 groups of 5 rats each. Group 1 (normal control) received olive oil and normal saline. Group 2 (BPH untreated group) received 3 mg/kg of testosterone propionate (TP) and normal saline, and group 3 (positive control) received 3 mg/kg of TP and 5 mg/kg of finasteride. Treatment groups 4, 5, 6, 7, 8, and 9 received 3 mg/kg of TP and a middle dose (200 mg/kg) of LD50 of ethanol crude tuber extract of C. esculenta (ECTECE) or hexane, dichloromethane, butanone, ethyl acetate and aqueous fractions of ECTECE respectively for a period of 28 days. Results The negative controls showed a significant (p  0.05) difference in the mean relative weights of most vital organs: liver, kidneys, and heart. This was also observed in hematological parameters: RBC, hemoglobin, HCT, MCV, MCH, MCHC, and platelets counts. In general, we note that the effects of the well-established drug finasteride on the biochemical parameters and histology of selected organs are comparable to those of C. esculenta fractions. Conclusion This study demonstrates that C. esculenta tuber extracts provide potentially safe nutraceutical if applied in the management of benign prostate hyperplasia based on a rat model

    AbstractOne of the prominent complications observed in those undergoing treatment with methotrexate (MTX) is hematological profile alterations which could culminate in severe anemia. In this study, we assessed the hematological profile indices in MXT-treated rats and the effect of leaf extract of Datura stramonium (LEDS) supplementation in MXT-treated rats. Ethanol (98%) was the solvent used in extraction. Animals were divided at random into four groups. Animals in group 1 received normal saline (5 mg/kg) orally and feeding was limitless and did not receive MXT. Animals in group 2 were given LEDS orally (200 mg/kg body weight) for 21 days while group 3 received 20 mg/kg body weight (bw) of MXT on day 18 via the intra-peritoneum without LEDS. Rats in group 4 were given the extract (200 mg/kg bw) and also injected with 20 mg/kg bw of MXT on day 18 of the study via the intra-peritoneum. Serum levels of hemoglobin, red blood cells, packed cell volume, total white blood cells, neutrophils, lymphocytes, and platelets were determined. Rats treated with MXT had notable depletion in hemoglobin, red blood cells, packed cell volume, total white blood cells, neutrophils, and platelets, unlike the control group. Interestingly, LEDS supplementation markedly restored the altered hematological profiles. MXT injection caused hematological dysfunction while co-supplementation with LEDS restored the impaired hematological indices. Therefore, LEDS could be a promising tool in arresting hematological dysfunctions accompanying MXT chemotherapy. However, we advocate for further prospective scrutiny

    Serine/arginine-rich splicing factor 7 promotes the type I interferon response by activating Irf7 transcription

    Summary: Tight regulation of macrophage immune gene expression is required to fight infection without risking harmful inflammation. The contribution of RNA-binding proteins (RBPs) to shaping the macrophage response to pathogens remains poorly understood. Transcriptomic analysis reveals that a member of the serine/arginine-rich (SR) family of mRNA processing factors, SRSF7, is required for optimal expression of a cohort of interferon-stimulated genes in macrophages. Using genetic and biochemical assays, we discover that in addition to its canonical role in regulating alternative splicing, SRSF7 drives transcription of interferon regulatory transcription factor 7 (IRF7) to promote antiviral immunity. At the Irf7 promoter, SRSF7 maximizes STAT1 transcription factor binding and RNA polymerase II elongation via cooperation with the H4K20me1 histone methyltransferase KMT5a (SET8). These studies define a role for an SR protein in activating transcription and reveal an RBP-chromatin network that orchestrates macrophage antiviral gene expression

    Xylopia aethiopica (XAE) is a commonly used herbal medicine and contains rich active ingredients for a variety of biological activities. The study aimed to explore the role of XAE in the management of benign prostatic hyperplasia (BPH). In the study, testosterone propionate-induced BPH in albino rats was established and treated with different concentrations of ethanol extract of XAE leaf. After treatment, the rats were sacrificed, and the body and prostate weights were recorded. The prostate-specific antigen (PSA) and acid phosphatase (ACP) levels in the blood samples were also determined. Gas chromatography-mass spectrometry was conducted to assess the active chemical compounds. Docking analysis was performed to screen chemical compounds by evaluating their binding affinity with two pro-BPH protein targets (cellular prostatic ACP and PSA). Our data showed the presence of 44 chemical compounds in XAE leaf extract. The body and prostate weights, as well as the levels of PSA and ACP, were significantly increased in BPH induction, and the changing trend was significantly reversed by additional XAE treatment. Interestingly, PSA and ACP levels in XAE-treated groups were reduced to almost the same levels as those in the healthy control. Docking analysis identified four top-posed compounds: ÎČ-amyrin, α-amyrin, α-amyrenone, and lupenone with stronger binding energies to prostatic ACP being −9.8, −8.3, −8.4, and −8.6, respectively, compared with the standard drug finasteride (−8.3). Furthermore, the two-dimensional analysis revealed strong interactions through hydrogen bonding, covalent interactions, and several van der Waal forces between the lead compounds and the target proteins. Notably, there was a recurrence interaction between similar residues Asn-1062, Lys-1250, Lys-1059, and Phe-1060 on the protein targets and the lead compounds. The study first revealed the role of XAE in BPH therapy and will help in drug design based on the lead compounds discovered in this work

    The study aimed to investigate how the solvent extract of Buchholzia coriacea (BCE), a widely known hypolipidemic agent, could contribute to hyperlipidemia treatment and identify the potential bioactive compounds. We studied Wistar albino rats, dividing them into seven groups: the normal control, normal rats treated with 400 mg/kg.b.wt of BCE (NRG group), the hyperlipidemic control (HPC group), hyperlipidemic rats treated with atorvastatin, a standard control drug (SC group), as well as 200, 400, and 800 mg/kg.b.wt of BCE extract respectively (T1, T2, T3 groups). The potential compounds that functioned in BCE extract were analyzed by in silico binding to acetyl-CoA carboxylase (ACC) and fatty acid synthase (FASN). The binding affinities and drug-like properties of the compounds were determined using virtual screening and absorption distribution metabolism excretion and toxicity prediction analysis. The gas chromatography-mass spectrometry analysis identified alkaloids, saponins, flavonoids, phenols, terpenoids, and 44 chemical compounds in the leaf extract of BCE. BCE significantly reduced the levels of triacylglycerol, total cholesterol, low-density lipoprotein, very low-density lipoprotein, atherogenic coefficient, atherogenic index, and coronary risk index, while enhancing the levels of high-density lipoprotein and cardioprotective index in comparison to the HPC group. The BCE reduced malondialdehyde quantities, which exhibit high levels in HPC. Superoxide dismutase and glutathione peroxidase activities as well as glutathione levels, which are otherwise reduced in HPC, were increased upon the BCE treatment. Among the identified BCE compounds, lupenone and 2,7-dimethylnaphthalene exhibited the highest binding affinities to ACC and FASN, suggesting that these two compounds might be the bioactive BCE components displaying hypolipidemic properties. BCE is found to be beneficial in blocking hyperlipidemia through the modulation of lipid profile, the protection of cardiovascular function, as well as the suppression of oxidative stress. BCE may be a natural source for exploring novel drugs for the treatment of dyslipidemia
