Daromosu, H, Morgan R, Adewara B.  2022.  Assessment of Retinal Nerve Fiber Layer Thickness in Nigerian Adults Using Spectral-Domain Optical Coherence Tomography, 2022/08/31. 30:63-68. Abstract

Objective: To measure the circumpapillary retinal nerve fiber layer (RNFL) thickness in normal eyes of Nigerian adults using spectral-domain optical coherence tomography (SD-OCT). Materials and methods: This was a cross-sectional study of normal eyes of Nigerian adults between July and September 2016 at the eye clinic of a tertiary hospital in Nigeria. Sociodemographic data, clinical history, and examination findings were obtained. Dipstick urinalysis and blood pressure measurements were performed. Circumpapillary RNFL thickness was measured with the Topcon 3D OCT-1 Maestro version 8.30 (Topcon Medical Systems, Inc., Oakland, NJ, USA), using the 3D optic nerve head analysis. Data were analyzed using the International Business Machine (IBM) Statistical Package for the Social Sciences (SPSS)Statistics, version 25.0 (IBM Corp., Armonk, NY, USA) and the level of significance was set at P < 0.05. Results: The study included 120participants (240 eyes) with an age range of 18 to 53 years and a mean age of 34.06 ± 7.64 years. There were 59 (49.17%) males and 61(50.83%) females. The average RNFL thickness in the right and left eyes was 112.26 ± 9.6 and 110.53 ± 9.14 mm, respectively. The average RNFL thickness for the Igbo ethnic group was 117.5 ± 7.69 and 115.04 ± 7.18 mm in the right and left eyes, respectively. The mean RNFL thickness for the inferior, superior, nasal, and temporal quadrants was 148.92 ± 15.77, 142.59 ± 16.48, 85.3 ± 15.39, and 71.89 ± 9.35 mm in the right eyes and 149.28 ± 16.03, 141.69 ± 13.33, 81.82 ± 13.59, and 68.8 ± 10.17 mm in the left eyes, respectively. Conclusion: This study showed the normal circumpapillary RNFL thickness values in Nigerian adults using SD-OCT. There were variations based on ethnicity that suggest it may be important to use ethnic-specific benchmarks when interpreting OCT results for the management of glaucoma.

Adedoja, O, Samways M, Kehinde T.  2021.  Age class of alien tree stands retained for mammal protection have differential effects on flower-visiting insect assemblages, 2021/07/10. Abstract

• Limited sunlight reduces plant productivity and foraging activities of pollinators, such as when alien trees shade out native flowering plants. The conservation management response is to remove the impoverishing effect of the alien tree canopy. However, alien trees can provide benefit for certain species when they provide significant scarce resources. We assess how flower-visiting insects respond to shading from young, small-sized, open canopy vs. mature, tall, closed-canopy alien pine trees retained specifically as refuges for certain rare mammals.• We sampled flower–visitor species diversity and interactions at various distances from pine stands of both sizes in a matrix of low sclerophyllous natural vegetation. We sampled flower–visitors using coloured pan traps and estimated flower–visitor interactions and flower diversity.
• Reduction in percentage light reaching the understorey significantly reduced flower abundance, with zero flowers in tall pine understorey. Flower–visitor species composition differed across sampling locations with increasing distance from tall pine understorey. Although pine tree size led to a decline in flower–visitor interaction frequency and network specialisation in all pine tree stands, some bee species that are mostly tree nesters, were observed in unique interactions in association with tall pines only.
• We show that alien pines, especially tall trees, have an impoverishing effect on flowering plants and flower–visitors. However, these trees also confer benefit to specialised groups such as tree-nesting bees. While active alien pine removal is encouraged where the trees are actively invading, maintaining well-contained small stands is of value for two different taxa of conservation concern.

The existence of riparian vegetation is greatly threatened by change in land uses in Nigeria and information on historical management of land use which influences riparian vegetation dynamics is critical to the conservation of plants species diversity. This information is poorly understood especially in Nigeria and by extension in Africa. This study therefore assessed the areas covered by riparian forests in Osun State, Nigeria in order to identify the main drivers of its decline using optical remote sensing data. It also assessed the availability and distribution of the riparian forests over three decades (1986-2016) using Landsat Enhanced Thematic Mapper (ETM). Results showed that the riparian forests covered 546.18km² (6.40%) with about 308riparian forests distributed across the state in 1986 but had declined to 176 by 2016. Three decades later, areas covered by riparian forests decreased to171.69km² (2.01%), representing a decline of about 69% and was predicted a rapid transition to disturbed lands. Human activities such as logging, farming, grazing and construction have greatly influenced the riparian vegetation cover with obvious decline in extent, distribution and quality. Observation from our case study showed that the disappearance of these forests is taken place at a rate that is faster than the predicted level of the Nigerian riparian forest loss by 2040. Notably deforestation, agriculture and urbanization are the main drivers of this decline, of the African gallery forests.

Ademola, A.  2021.  Asymptotic behaviour of solutions to certain nonlinear third order neutral functional differential equation, 2021/04/01. 7:e06615. Abstract

This paper presents asymptotic behaviour of solution to certain nonlinear nonautonomous neutral functional differential equation of the third order. The third order functional differential equation is cut back to system of first order and used together with a quadratic function to acquire suitable complete Lyapunov-Krasovskii functional. This functional is tested and employed to set up conditions on the nonlinear terms to guarantee stability, asymptotic stability, uniform stability, uniform asymptotic stability of the trivial solution, ultimate boundedness and uniform ultimate boundedness of the nontrivial solutions of the equations under consideration. The results of this paper are new as there are no existing results on the type of equation discussed. Examples are also given to validate the theoretical results.

Danjuma, D-A, Maza D, Stephen O, Akinlade G, Maza S, Olukotun G, Olubunmi A.  2021.  American Journal of Mathematical and Computer Modelling A Human Physiologically-based Bio-kinetic Model for Cadmium A Human Physiologically-based Bio-kinetic Model for, 2021/02/18. 6:9-13. Abstract

A physiologically-based bio-kinetic (PBBK) model, capable of simulating the absorption, distribution, and elimination of cadmium in humans has been developed. The formulation of this model was based on human data cleaned from literature. The liver, kidney, lung, artery, vein, stomach, small intestine and remainder of the body (other tissues not modelled explicitly) were modelled as compartments. While transfer rate coefficients were used to describe the kinetics of cadmium in the gastrointestinal track, the model used blood flow rates and partition coefficients rather than the traditional transfer rate coefficients to describe the distribution and accumulation of the chemical into critical organs such as liver, kidney and remainder of the body. A perfusion rate-limited kinetics model was assumed for these critical organs, where each of these tissues was regarded as a well-stirred compartment, without any concentration gradient within the compartment. The partition coefficients for critical organs modelled, along with transfer rate coefficients describing oral ingestion and inhalation were estimated by fitting the simulated concentration of cadmium in the liver, kidney and urine to observed concentrations found in literature. The model was capable of simulating, to a good degree of success, the results of empirical observations and other simulations found in literature. Simulations by the model also indicate that the partition coefficient of cadmium for the kidney, liver and other critical organs was higher in smokers.
