Nutrient Composition and Sensory Properties of Breakfast Cereals Produced from Millet Flour Supplemented with Soybean and Date Fruit Flours
Authors: Ahmadu D. L. , Okoye J. I. , Egbujie A. E. 
Published: June 2023

This study was designed to evaluate the nutrient composition and sensory properties of breakfast cereals produced from blends of millet, soybean and date fruit flour. Soybean and date fruit flours were used at varying replacement levels (5-30% soybean and 5-20% date fruit) for malted millet flour in the production of breakfast cereals with breakfast cereal produced from 100% malted millet flour as control. The nutrient composition and sensory properties of the breakfast cereals were evaluated using standard methods. The moisture, crude protein, fat, crude fibre and ash contents of the breakfast cereals increased significantly (p<0.05) with increase in substitution of soybean and date fruit flours from 7.19-7.63%, 7.69-18.32%, 3.09-4.03%, 2.47-3.86% and 1.21-2.07, respectively, while the carbohydrate and energy contents decreased from 78.37-64.13% and 371.99-365.10KJ/100g, respectively. The mineral composition of the breakfast cereals also increased significantly (p<0.05) with increase in substitution of soybean and date fruit flours from 17.86-96.52mg/100g (calcium), 58.47-132.72mg/100g (potassium), 79.01-120.76mg/100g (phosphorus), 16.54-86.54mg/100g (magnesium), 1.55-2.14mg/100g (iron) and 1.32-1.72mg/100g (zinc), respectively. The thiamine, riboflavin, niacin, ascorbic acid, vitamin A and folic acid contents of the samples equally increased significantly (p<0.05) with increase in substitution of soybean and date fruit flours from 1.36-2.57mg/100g, 2.36-3.51mg/100g, 2.14-3.56mg/100g, 1.55-2.22mg/100g, 2.23-4.26mg/100g and 1.02-1.81mg/100g, respectively. The sensory properties of the samples showed that the porridge made from the control sample (Breakfast cereal made with 100% malted millet flour) was the most acceptable to the panelists and also differed significantly (p<0.05) from those prepared from the substituted samples in colour, texture, taste and flavour. The study, however, showed that the nutrient contents and sensory properties of millet based breakfast cereals could be improved by supplementing millet flour with different proportions of soybean and date fruit flours in the preparation of nutrient-dense and acceptable breakfast cereal products.

Published: June 2023

Aims: This study aimed to compare local variants of X. americana with optimal properties for production in the food and phytomedicine industry.
Methodology: The plant material was collected from three sites in Burkina Faso, namely Gonsé, Saponé and Kokologho from May to June 2021. The oil yield was estimated and the physicochemical parameters were performed according to ISO standards. Phytochemical screening of polyphenols and flavonoids was carried out and the antioxidant activities of the oils from different trees were evaluated using DPPH and ABTS tests.
Results: The average oil extraction yield for the three variants was 42.30 ± 14.34%.The estimated colour oil was yellow. The oil refraction index indicated that the Gonsé site (1.471 ± 0.002) has the highest value. The highest oil temperature value was obtained from Kokologho trees (30.60 ± 0.21°C) followed by the ones collected at Gonsé (22.63 ± 1.72°C) and Saponé (22.60 ± 0.41°C). The oil acid value of almonds from all three sites with an average value of 0.023 ± 0.013 mg KOH/g was lower than the international standard ISO 660-2020. The Saponé and Kokologho sites exhibited the highest oil peroxide values of 0.040 ± 0.000 mEq O2/kg on either side, while the lowest peroxide value was found at Gonsé (0.021 ± 0.000 mEq O2/kg). The highest saponification value is that of Kokologho with a value of 84.81 ± 4.18 mg KOH/g. The polyphenol and flavonoid content of almond oil vary within a site and between sites. Oil extracts have shown free radical scavenging capabilities (DPPH and ABTS) indicating substantial polyphenol and flavonoid content.
Conclusion: The oil has very good quality and fulfills all standard requirements for use in the phytomedicine and food industry. A mass selection can be performed within the three sites for X. americana plantation in agroforestry systems.

Published: June 2023

Background: Nasofacial Anthropometry is concerned with the measurements of the proportions, size and shape of the human nose and face [1]. This study was aimed at investigating the nasofacial dimensions in Ekpeye tribe in Rivers state.
Methods: Nasofacial parameters of 362 adults were measured using vernier calliper. The nasal length was measured as the distance between the nasion and the nasopinale; nasal width was measured as the distance between ala to ala. The morphological facial length was measured as the distance from the nasion to gnathion and morphological facial width was measured as the distance between right and left zygomatic arches.
Results: Data obtained was analyzed using SPSS version 26.0 and Microsoft Excel 2013. The mean nasal index for the males was 95.03±17.31 while females presented with 91.04±10.39, this is statistically significant. The mean facial index for the males was 101.72±59.52 while females presented with 93.18±12.65.
Conclusion: In this study, it was observed that the Ekpeye people have platyrrhine type of nose and Hyperleptoprosopic category of face. Hence the data in this study has provided anthropometric data for the Ekpeye people, which will be beneficial in forensic science and nasofacial reconstructive surgeries.

Published: June 2023

Aim: The primary aim of the present study was to screen the salt tolerant calli and optimization of in-vitro regeneration protocol from selected screen calli.
Methodology: The cotyledonary leaf explants was sterilized by using 1% Bavistin, 0.1% Mercuric chloride and 70% ethanol followed by washing with distilled water. Sterilized explants were cultured on Murashige and Skoog (MS) medium supplemented with different concentration of NaCl (i.e. 0, 50mM, 100mM, 200mM, 300 mM and 400 mM) to check the salinity tolerance ability of PKV pink genotype. In vitro screening of callus was studied by morphological characters like colour and texture of callus, callus growth percentage, relative water contained, cell survivility and proline content from saline stress and unstress calli to confirm the saline tolerance pressure to regenerate the PKV Pink safflower genotype.
Results: MS medium supplemented with 150 mM NaCl showed 50% survival of calli, whereas no growth was obtained in high concentration of NaCl. Moreover, biochemical assay like proline estimation was done for its confirmation from different NaCl stress and unstress calli. The proline accumulation found to be highest callus grown on MS media supplemented with 150 mM NaCl as compared to control. Also studied the morphological observation i.e. colour and texture of calli, callus growth percentage, relative water content and cell viability under different NaCl stress to select the saline tolerance pressure to regenerate the tolerance line in PKV Pink. The saline tolerance shoots failed to produce in vitro rooting on the standardized rooting medium. So, the different approach like higher auxin shock and grafting experiment were attempted to overcome the rooting problem. Higher auxin shock experiment failed but grafting approach found satisfactory to overcome the rooting in saline tolerance shoot and for development of saline tolerance line in PKV Pink safflower genotype.
Conclusion: The development of abiotic stress tolerance plants found the better understanding of physiological and biochemical changes in plants under in vitro stress conditions.

ImportanceUse of oral vitamin K antagonists (VKAs) may place patients undergoing endovascular thrombectomy (EVT) for acute ischemic stroke caused by large vessel occlusion at increased risk of complications.ObjectiveTo determine the association between recent use of a VKA and outcomes among patients selected to undergo EVT in clinical practice.Design, Setting, and ParticipantsRetrospective, observational cohort study based on the American Heart Association’s Get With the Guidelines–Stroke Program between October 2015 and March 2020. From 594 participating hospitals in the US, 32 715 patients with acute ischemic stroke selected to undergo EVT within 6 hours of time last known to be well were included.ExposureVKA use within the 7 days prior to hospital arrival.Main Outcome and MeasuresThe primary end point was symptomatic intracranial hemorrhage (sICH). Secondary end points included life-threatening systemic hemorrhage, another serious complication, any complications of reperfusion therapy, in-hospital mortality, and in-hospital mortality or discharge to hospice.ResultsOf 32 715 patients (median age, 72 years; 50.7% female), 3087 (9.4%) had used a VKA (median international normalized ratio [INR], 1.5 [IQR, 1.2-1.9]) and 29 628 had not used a VKA prior to hospital presentation. Overall, prior VKA use was not significantly associated with an increased risk of sICH (211/3087 patients [6.8%] taking a VKA compared with 1904/29 628 patients [6.4%] not taking a VKA; adjusted odds ratio [OR], 1.12 [95% CI, 0.94-1.35]; adjusted risk difference, 0.69% [95% CI, −0.39% to 1.77%]). Among 830 patients taking a VKA with an INR greater than 1.7, sICH risk was significantly higher than in those not taking a VKA (8.3% vs 6.4%; adjusted OR, 1.88 [95% CI, 1.33-2.65]; adjusted risk difference, 4.03% [95% CI, 1.53%-6.53%]), while those with an INR of 1.7 or lower (n = 1585) had no significant difference in the risk of sICH (6.7% vs 6.4%; adjusted OR, 1.24 [95% CI, 0.87-1.76]; adjusted risk difference, 1.13% [95% CI, −0.79% to 3.04%]). Of 5 prespecified secondary end points, none showed a significant difference across VKA-exposed vs VKA-unexposed groups.Conclusions and RelevanceAmong patients with acute ischemic stroke selected to receive EVT, VKA use within the preceding 7 days was not associated with a significantly increased risk of sICH overall. However, recent VKA use with a presenting INR greater than 1.7 was associated with a significantly increased risk of sICH compared with no use of anticoagulants.
Evidence of Lack of Treatment Efficacy Derived From Statistically Nonsignificant Results of Randomized Clinical Trials
Authors: Perneger Thomas , Gayet-Ageron Angèle 
Published: June 2023

ImportanceMany randomized clinical trials yield statistically nonsignificant results. Such results are difficult to interpret within the dominant statistical framework.ObjectiveTo estimate the strength of evidence in favor of the null hypothesis of no effect vs the prespecified effectiveness hypothesis among nonsignificant primary outcome results of randomized clinical trials by application of the likelihood ratio.Design, Setting, and ParticipantsCross-sectional study of statistically nonsignificant results for primary outcomes of randomized clinical trials published in 6 leading general medical journals in 2021.Outcome measuresThe likelihood ratio for the null hypothesis of no effect vs the effectiveness hypothesis stated in the trial protocol (alternate hypothesis). The likelihood ratio quantifies the support that the data provide to one hypothesis vs the other.ResultsIn 130 articles that reported 169 statistically nonsignificant results for primary outcomes, 15 results (8.9%) favored the alternate hypothesis (likelihood ratio, &amp;lt;1), and 154 (91.1%) favored the null hypothesis of no effect (likelihood ratio, &amp;gt;1). For 117 (69.2%), the likelihood ratio exceeded 10; for 88 (52.1%), it exceeded 100; and for 50 (29.6%), it exceeded 1000. Likelihood ratios were only weakly correlated withPvalues (Spearmanr, 0.16;P = .045).ConclusionsA large proportion of statistically nonsignificant primary outcome results of randomized clinical trials provided strong support for the hypothesis of no effect vs the alternate hypothesis of clinical efficacy stated a priori. Reporting the likelihood ratio may improve the interpretation of clinical trials, particularly when observed differences in the primary outcome are statistically nonsignificant.
