Jegede, T, Tunde-Ayinmode M, Jegede T, Akinsulore A, Ibigbami O.  2021.  Bullying Behavior Roles and Mental Health Correlates Among Secondary School Students in Ilesa, Nigeria, 2021/07/01. Abstract

Objective: Bullying behaviour is pervasive, cuts across age group, transcends geographical location and its impacts include but not limited to physical or academic snags. The objective of the study is to determine bullying roles and their association with emotional or behavioural problems among adolescents in Ilesa, Nigeria. Methods: A cross-sectional study was performed on 432 senior secondary school students (12-18 years old) in Ilesa (Nigeria). Peer Relationship Questionnaire was used to determine bullying roles and the Strength and Difficulty Questionnaire to measure behavioural problems. Results: Prevalence of bullying behaviour is high. The bully-victims had the highest means score on all subscales except pro-social. Similarly, the bully-victims was significantly associated with all subscales of the SDQ except the pro-social problems at (P< .001), (P=.024), (P= .004), (P= .004), and (P< .001) for conduct, emotional problem, hyperactivity problem, peer relationship problem and the total difficulty score respectively. Conclusion: This shows that participating in bullying behaviour irrespective of the role played increases the likelihood of psychological consequences, especially the bully-victim. There is a need to establish anti-bullying programs in schools to curb this menace and its mental health consequence.

Mahmoud, B, Mirghni AA, Fasakin O, Oyedotun K, Manyala N.  2020.  Bullet-like microstructured nickel ammonium phosphate/graphene foam composite as positive electrode for asymmetric supercapacitors, 2020/04/23. 10:16349-16360. Abstract

Unique microstructured nickel ammonium phosphate Ni(NH4)2(PO3)4·4H2O and Ni(NH4)2(PO3)4·4H2O/GF composite were successfully synthesized through the hydrothermal method with different graphene foam (GF) mass loading of 30, 60 and 90 mg as a positive electrode for asymmetric supercapacitors. The crystal structure, vibrational mode, texture and morphology of the samples were studied with X-ray diffraction (XRD), Raman spectroscopy, Brunauer–Emmett–Teller (BET) surface area analysis and scanning electron microscopy (SEM). The prepared materials were tested in both 3-and 2-electrode measurements using 6 M KOH electrolyte. The composite material Ni(NH4)2(PO3)4·4H2O/60 mg exhibited a remarkable gravimetric capacity of 52 mA h g⁻¹, higher than the 34 mA h g⁻¹ obtained for the Ni(NH4)2(PO3)4·4H2O pristine sample, both at 0.5 A g⁻¹. For the fabrication of the asymmetric device, activated carbon from pepper seed (ppAC) was used as a negative electrode while Ni(NH4)2(PO3)4·4H2O/60 mg GF was adopted as the positive electrode. The Ni(NH4)2(PO3)4·4H2O/60 mg GF//ppAC asymmetric device delivered a specific energy of 52 Wh kg⁻¹ with an equivalent specific power of 861 W kg⁻¹ at 1.0 A g⁻¹ within a potential range of 0.0–1.5 V. Moreover, the asymmetric device displayed a capacity retention of about 76% for over 10 000 cycles at a high specific current of 10.0 A g⁻¹.

Jaiyeola, T, Effiong G.  2018.  Basarab loop and its variance with inverse properties, 2018/12/01. 26:229-238. Abstract

A loop (Q, ·) is called a Basarab loop if the identities: (x · yxρ)(xz) = x · yz and (yx) · (xλz · x) = yz · x hold. It is a special type of a G-loop. It was shown that a Basarab loop (Q, ·) has the cross inverse property if and only if (Q, ·) is an abelian group or all left (right) translations of (Q, ·) are right (left) regular. In a Basarab loop, the following propertiesare equivalent: flexibility property, right inverse property, left inverse property, inverse property, right alternative property, left alternative property and alternative property. The following were
proved: a Basarab loop is a weak inverse property loop if it is flexible such that the middle inner mapping is contained in a permutation group; a Basarab loop is an automorphic inverse property
loop if a semi-commutative law is obeyed such that the middle inner mapping is contained in a permutation group; a Basarab loop is an anti-automorphic inverse property loop if every element
has a two-sided inverse such that the middle inner mapping is contained in a permutation group; a Basarab loop is a semi-automorphic inverse property loop if the Basarab loop is flexible, the
middle inner mapping is contained in a permutation group such that a semi-cross inverse property holds; a Basarab loop with the m-inverse property such that a permutation condition is true is
a cross inverse property loop if it is flexible. Necessary and sufficient conditions for a Basarab loop to be of exponent 2 or a centrum square were established.

Objective: This study was done to investigate the effect(s) of glaucoma on the ocular optic nerve sheath diameter and lens thickness using B-mode ultrasonography. Materials and methods: One hundred and twenty study participants were recruited; 60 subjects with glaucoma and 60 age-and sex-matched controls without glaucoma. The optic nerve sheath diameter and lens thickness of both eyes were measured using a linear high frequency transducer with frequency of 6.5-12MHz. Results: The mean optic nerve sheath diameter of the glaucomatous eyes (3.57 ± 0.19mm and 3.59 ± 0.33mm on the right and left, respectively) were significantly thinner than that of controls (4.23 ± 0.34 mm and 4.26 ± 0.30 mm on the right and left, respectively; p < 0.001). There is increased mean lens thickness in the glaucomatous eyes (4.15 ± 0.43mm and 4.18 ± 0.46mm on the right and left, respectively) than in the controls (4.01 ± 0.56mm and 3.99 ± 0.45mm on the right and left, respectively) with a statistically significant difference seen in the left eye (p = 0.024). Conclusion: B-mode ultrasound is a reliable tool of assessing the nerve sheath diameter and lens thickness in glaucoma. Optic nerve sheath diameter is reduced in glaucoma.

Fadeiye, E, OC O, Soyoye D, RT I, TM O, TM O, O K, Ilona P.  2018.  Blood-glucose-response-on-consumption-of-cassava-varieties-garri-in-healthy Nigerian-subjects, 2018/01/18. 02 Abstract

Cassava is an important staple consumed in various forms by humans. The glycemic index and load of some Nigerian foods are well documented, but not much is documented on Vitamin A bio-fortified pruned cassava. The study determined blood glucose response in normal freeliving volunteer adults after consumption of vitamin A bio-fortified normally grown cassava (A), vitamin A bio-fortified pruned cassava (B) and non-bio-fortified normally grown cassava (C). The study employed single blind, randomized, cross-over investigation on 40 consenting apparently healthy adult volunteers with a documented normal fasting blood glucose level prior to recruitment. Fasting blood sugar level and post prandial of the participants were obtained on each day of the study after the consumption of 360 g of treatments (A, B&C eba) which was equivalent to 75 g anhydrous glucose using Accu-check glucometer. The treatments were served with vegetable soup prepared with fish and was administered to the subjects in a randomized manner. Oral glucose D was used as standard food. Post prandial glucose response (mg/dL) was obtained at 1 hour and 2 hours respectively. Data analyses were done using SPSS (version 22). Descriptive analysis was carried out and data were presented in percentages/proportions, means and standard deviations at 0.05% level of confidence. The 2 hours glucose post prandial (2 hrpp) for Treatment A, B and C in Mg/dL were 92.24, 94.74 and 98.91, while the glycemic loads were 308.0, 297.0 and 316.2 respectively. Treatment B had the lowest glycemic load. It was concluded that vitamin A bio-fortified cassava (especially when pruned before harvesting) had a lower post prandial glucose response, lower carbohydrate content and lowest glycemic load when compared to the non-bio-fortified conventional Garri. This variety of cassava may be better tolerated by people with metabolic disease/diabetes mellitus.

Biopreservation and Biobanking. 16(3) Abstract

Africa was previously insufficiently represented in the emerging discipline of biobanking despite commendable early efforts. However, with the Human, Heredity, and Health in Africa (H3Africa) initiative, biorepository science has been bolstered, regional biobanks are springing up, and awareness about biobanks is growing on the continent. The Stroke Investigative Research and Educational Network (SIREN) project is a transnational, multicenter, hospital and community-based study involving over 3000 cases and 3000 controls recruited from 16 sites in Ghana and Nigeria. SIREN aims to explore and unravel the genetic and environmental factors that interact to produce the peculiar phenotypic and clinical characteristics of stroke as seen in people of African ancestry and facilitate the development of new diagnostics, therapeutics, and preventative strategies. The aim of this article is to describe our experience with the development of the procedure for collection, processing, storage, and shipment of biological samples (blood, serum, plasma, buffy coat, red cell concentrates, and DNA) and brain imaging across coordinating and participating sites within the SIREN Project. The SIREN network was initiated in 2014 with support and funding from the H3Africa Initiative. The SIREN Biobank currently has 3015 brain images, 92,950 blood fractions (serum, plasma, red cell concentrates, and buffy coat) accrued from 8450 recruited subjects, and quantified and aliquoted good-quality DNA extracts from 6150 study subjects. This represents an invaluable resource for future research with expanding genomic and trans-omic technologies. This will facilitate the involvement of indigenous African samples in cutting-edge stroke genomics and trans-omics research. It is, however, critical to effectively engage African stroke patients and community members who have contributed precious biological materials to the SIREN Biobank to generate appropriate evidence base for dealing with ethical, legal, and social issues of privacy, autonomy, identifiability, biorights, governance issues, and public understanding of stroke biobanking in the context of unique African culture, language, and belief systems.
