Background: Anastatica hierochuntica L. (Brassicaceae) has been claimed to treat various conditions, including complicated childbirth. The principal objective of this research was to provide scientific evidence on the contractile effect of the aqueous and hydroethanolic extracts of the whole plant from A. hierochuntica during labor. Method: Qualitative and quantitative methods helped identify and quantify the phytoconstituents in both extracts. The antioxidant activity was studied using four standard methods (ABTS, DPPH, FRAP, and LPO). Results: The inhibitory power of the extracts on pro-inflammatory enzymes such as 15-lipoxygenase and phospholipase A2 was determined. The contractile effects of the extracts were evaluated using isolated pregnant mice uteri. Steroids, triterpenoids, flavonoids, tannins, coumarins, and reduced compounds were identified in both extracts. The hydroethanolic extract exhibited higher content of hydrolyzable tannins (15.07 ± 0.24 mg tannic acid equivalent/g) than the aqueous decoction (11.8 ± 0.69 mg TAE/g). The extracts demonstrated the ability to scavenge DPPH and ABTS radicals, reduce ferric ions, and inhibit especially lipid peroxidation. No significant difference was noted in the phospholipase inhibition between the extracts and betamethasone. The hydroethanolic extract displayed the most significant anti-lipoxygenase activity with an IC50 value of 55.82 ± 1.15 μg/mL. The lethal dose (LD50) of extracts was estimated to be superior to 2000 mg/kg body weight (bw). The ability of the samples to produce one cm amplitude of contraction at 50% effective concentrations (EC50) was 5.33 × 10−8 ± 0.32 mg/mL for oxytocin, 1.51 ± 0.08 mg/mL for aqueous extract and 3.57 ± 0.61 mg/mL for hydroethanolic extract. Conclusion: These findings could provide evidence for using Anastatica hierochuntica to facilitate childbirth.

Background: The investigation of toxin genes in strains involved in staphylococcal food poisoning contributes to food safety. The aim of this study was to isolate and identify enterotoxigenic Staphylococcus strains from dried, smoked, and braised fish sold in ouagadougou markets. Methodology: Staphylococci were isolated using standard microbiology methods. Staphylococcus strains were identified using API Staph kit (Reference # 20500, BioMerieux S.A., Marcy l'Etoile, France). The molecular identification of isolated Staphylococcus aureus strains was specifically confirmed by PCR using the Staur4 and Staur6 primers. The genes encoding enterotoxins, enterotoxin-like toxins, exfoliative toxins, and TSST-1 toxin were detected by multiplex PCR using specific primers from Inquaba Biotec West Africa Ltd, Africa's Genomics Company. Results: The results of the microbiological quality assessment indicated that most of the samples analyzed were found to be of unsatisfactory microbiological quality according to the Staphylococcus aureus microbiological criteria (m = 102). Overall, only 12.55% of samples were satisfactory, while 97.45% were unsatisfactory. The STAPH API gallery allowed the identification of the following species: Staphylococcus aureus, Staphylococcus xylosus, Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus haemolyticus, Staphylococcus lentus, Staphylococcus sciuri and Staphylococcus capitis. Of the 108 Staphylococcus isolates, 81 (75%) showed at least one (1) toxin gene. Among the 21 toxin genes tested in this study, 20 genes were detected in all strains analyzed. The staphylococcal toxin genes detected were present in both Staphylococcus aureus and the other coagulase-negative strains isolated in this study. In addition, these genes are found individually or in association in certain strains. The most frequent genes detected in toxin gene-positive strains were: the tsst-1 gene in 45 isolated strains (41.7%), sei (16/14.8%), seg (13/12%), ser (

作者： Yobi Alexis Sawadogo Emmanuel ouédraogo Adama ouattara Issa ouédraogo Sibraogo Kiemtoré Charlemagne ouedraogo Department of Obstetrics and Gynaecology Bogodogo University Hospital Ouagadougou Burkina Faso Health Science Training and Research Unit Joseph Ki-Zerbo University Ouagadougou Burkina Faso Department of Obstetrics and Gynaecology Ouahigouya Regional University Hospital Ouahigouya Burkina Faso Department of Obstetrics and Gynaecology Yalgado Oudraogo University Hospital Ouagadougou Burkina Faso

Splenic injury caused by abdominal trauma during pregnancy is rare. Splenic injury associated with fetal death in utero following a fall from a tree top is even rarer. The authors report a case of splenic trauma associated with fetal death in utero following a fall from the top of a tree in a 19-year-old pregnant woman at 30 weeks amenorrhoea. She was referred from a 1st level health facility for trauma that had occurred the day before admission. She was in poor general condition (WHO performance status IV) and had a cardiovascular collapse. Ultrasound was used to diagnose haemoperitoneum and fetal death in utero. A CT scan was used to diagnose splenic lesions. Treatment consisted of splenectomy and caesarean section after resuscitation.

ACAZY is a plant formula used in traditional medicine in Burkina Faso to treat respiratory infections. After phytochemical analysis, this study evaluated extracts’ anti-inflammatory, antioxidant and antibacterial properties from the ACAZY recipe. Three extractions, an aqueous macerate (AM), an aqueous decoction (AD) and an hydroethanolic macerate (HEM) of the ACAZY recipe powder were carried out. Phytochemical screening of the extracts was carried out using high-performance thin-layer chromatography (HPTLC) and the determination of phenolic compounds. The anti-inflammatory potential was assessed in vitro using pro-inflammatory enzyme inhibition tests. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and Ferric-reducing antioxidant power (FRAP) antioxidant properties were also determined. The antibacterial activity was evaluated on Staphylococcus aureus and Streptococcus pneumoniae strains. Phytochemical analysis revealed the presence of flavonoids, saponins, tannins, anthracenosids, sterols and triterpenes in the extracts. The extracts inhibited pro-inflammatory enzymes by more than 40% at only 100 µg/mL. The extracts also showed potent antibacterial activity with a minimum inhibitory concentration 1 mg/mL on Staphylococcus aureus and 2 mg/mL on Streptococcus pneumoniae. The extracts in the ACAZY formula have shown anti-inflammatory and antioxidant properties in vitro. The AD also showed an antibacterial activity. This justifies its use in traditional medicine to treat acute respiratory infections.

Introduction: Sleep disorders among professional drivers are a major road safety problem. They cause fatigue and drowsiness at the wheel, which can lead to road traffic accidents and even accidents at work. The aim of this study was to assess sleep disorders among professional drivers of oil tankers in ouagadougou, Burkina Faso. Methods: This was a descriptive and analytical cross-sectional study carried out from 11 April 2020 to 11 September 2020 in the national hydrocarbon company’s fuel depot. All the drivers present at the time were included and accomplished a questionnaire incorporating the commonly scales using to assess sleep disorders, sleep quality and sleep apnoea. Data analysis using R 3.6.1 software enabled to perform univariate and multivariate analyses to identify associated factors. Adjusted odd ratios were used to measure the strength of association. The significance level chosen was p ≤ 0.05. Results: All the 339 respondents were male. A proportion of 33.6% suffered from insomnia, including 12.7% with moderate to severe insomnia, and 18.58% were at risk of sleep apnoea. On the Epworth scale, 26.6% of drivers showed sleep debt and 4.1% excessive daytime sleepiness. The risk factors associated with insomnia were the use of psychostimulants. A history of diabetes and insomnia were risk factors associated with sleep apnoea syndrome. Conclusion: The prevalence of sleep disturbance and insomnia among the respondents were 52.2% and 33.6% respectively. Use of psychostimulants was the identified risk factor. The prevalence of SAS was 4.72%, with diabetes and insomnia as associated factors.

Background: Life-threatening subdural hematoma is commonly related to trauma and rarely revealed by neoplasm. Observation: We report a case of a 53-year-old suffering from mild headache and without a history of trauma, was admitted unconscious due to a subdural hematoma on radiological investigations. Beside the left subdural hematoma, there was also alytic lesion of the sphenoid wing and the temporal bone on the same side. An emergent removal of the subdural hematoma and an excision of the bone lesion were performed. Pathological examination diagnosed a cavernous hemangioma of the skull. The postoperative period was uneventful with a dramatic recovery of the patient. Conclusion: A quick worsening of a chronic headache, acute impairment of an uncommon headache deserve prompt investigation and emergent surgical management in case of intracranial hematoma. Any bone and dural abnormalities at the vicinity of a subdural hematoma require total excision with clean border and pathological examination.

The quadratic boost is studied under its real model. The equations, of the continuous conduction mode, descriptive of this model are established. From these equations, the expressions of the voltage gain and the efficiency are extracted. These two quantities are plotted as a function of the duty cycle in order to appreciate them in different operating points of the transistor. The values of the different components have also been extracted for the fabrication of a prototype of the converter. Thanks to a set of experimental measurements at the input as well as at the output of the prototype converter, the voltage gain and the efficiency could also be observed. These were also plotted for different loads to observe converter behavior. The theoretical curves were compared with the experimental curves which allowed to validate the proposed mathematical models on a large range of duty cycles.

Cancer is one of the deadliest diseases in developing countries. In recent years, natural plant-based compounds have been used in the search for drugs to combat numerous diseases, including cancer. In this study, we evaluate the cytotoxic properties of paanfo tiben 1 and paanfo tiben 2, two traditional herbal formulations from Burkina Faso used in the treatment of cancer in Burkina Faso. To this end, the recipes were infused and freeze-dried. The dry extracts obtained were used to determine total phenolics and flavonoids content, assess antioxidant activity using the DPPH, ABTS and FRAP methods, evaluate anti-inflammatory properties by inhibiting 15-LOX, COX 1 and 2, and assess cytotoxic activity on HeLa cervical cancer and HePG2 liver cancer cell lines using the MTT test. The paanfo tiben 1 recipe showed the highest levels of total phenolics and flavonoids, as well as the best antioxidant activities, with IC50 values of 21.020 ± 0.6 µg/ml and 22.94 ± 0.57 µg/ml for DPPH and ABTS, and 165.15 mM EAA/mg dry extract for FRAP. It also exhibited the best cytotoxic activity with IC50 values of 112.02 ± 0.025 µg/ml on HeLa cells and 80.67 ± 6.08 µg/ml on HepG2 cells. On the other hand, paanfo tiben 2 exhibited the best anti-inflammatory activities through inhibition of 15-LOX and COX 1, with inhibition percentages at 100 µg/ml of 32.523% and 24.717 % respectively. These results could justify the traditional use of these two recipes by traditional health practitioners in the treatment of cancer sufferers in Burkina Faso.

Open Journal of Applied Sciences 2024年第4期14卷 849-864页

作者： Amana Metuor Dabiré Nicolas ouédraogo Cheick Alassane Djibila Damis Yves Patrik Bouniounou Molecular Biology and Genetics Laboratory (LABIOGENE) Universit&#233 Joseph Ki-Zerbo Ouagadougou Burkina Faso Training and Research Unit in Applied Sciences and Technologies Department of Biochemistry Microbiology University of Dedougou Dedougou Burkina Faso National Center for Research and Training on Malaria (CNRFP) Ouagadougou Burkina Faso

Sorghum beer or dolo is part of the eating habits of part of the population of Dédougou because of its low price compared with industrial beers. Its production is an ancestral tradition that uses traditional equipment and gives dolo organoleptic properties that are not found in industrial beers. The production process involves several stages, including fermentation, which itself comprises natural lactic fermentation followed by alcoholic fermentation using traditional yeasts, which are not controlled in any way. The general aim of this study is to assess the microbiological quality of these fermentative yeasts in the town of Dédougou, in order to contribute to the health safety of the population and the promotion of these local beers. Twenty samples of fermenting yeast were analyzed according to ISO standards, to isolate enterobacteria, total and faecal coliforms according to standard procedures for isolating these micro-organisms. The isolated strains were identified using the API20E gallery. Microbiological analyses revealed the presence of 51.17% enterobacteria, 45.38% total coliforms and 3.45% thermotolerant coliforms. We counted 40% Escherichia coli, 20% Enterobacter cloacae, 20% Klebsiella pneumoniae and 20% Klebsiella spp. All the strains detected are capable of surviving in hostile conditions and could harm the quality of the dolo, consumer health and cause real collective food poisoning in the town of Dédougou. This enabled us to assess the microbial quality of these yeasts and to propose more suitable measures for producing and preserving dolo under hygienic conditions to protect consumer health.
