The Bima Sandstone is an alluvial fan to braided river sedimentation that represents purely a siliciclastic depositional system. It is the oldest formation and the main reservoir unit in the entire Benue Trough. Porosity loss is an essential component of petroleum reservoirs that needs to be properly investigated for the purpose of hydrocarbon exploitation. Compaction and cementation processes are partly responsible for porosity loss in many known reservoirs around the world. Outcropping units of the formation around Lakwaime and Dogon Dutsi in Yola Sub-basin have been subjected to an integrated approach involving field observations, petrographic analysis and porosity measurements in order to understand the contribution of each of the processes. Modal composition of the samples shows that they are mostly lithic arkose to feldspathic litharenite, with quartz as the most common detrital mineral grain. Grain fracturing has been attributed to mechanical compaction, whereas grain contacts like sutured and concavo-convex are products of chemical compaction. The average values of compactional-porosity loss (COPL), cementational-porosity loss (CEPL), and compaction index (ICOMPACT) in the studied samples stand at 19.51%, 4.18% and 0.82 respectively. The study indicates that the role of compaction in porosity loss is greater than that of cementation as shown by the COPL-CEPL diagram and, as such considered to be generally responsible for the porosity loss in Bima Sandstone.

The environment faces significant global health challenges due to the presence of heavy metals, with harmful substances being discharged into the lithosphere, hydrosphere, and atmosphere. This study focused on assessing the cytotoxic effects of heavy metals recovered from dumpsites on the meristematic tissue of root tips of Allium cepa L. Soil samples, collected from central dumpsites containing heavy metals, underwent standard procedures. The concentrations of heavy metals in the samples were determined using the Association Official Analytical Chemist (AOAC) method. Each sample was digested with acids, neutralized with Calcium Oxide (CaO), and used to grow Allium cepa at varying concentrations, determining the LD50 of each sample. The LD50 concentrations were then employed to investigate cytotoxic effects on Allium cepa using standard techniques. Processed soil samples yielded Pb, Cr, Cd, Ni, Co, Zn, Fe, and Cu at different concentrations, many of which exceeded the WHO standard values. The mitotic index ranged from 5.34 ± 0.01 to 10.36 ± 0.00, 5.34 ± 0.00 to 13.16 ± 0.01, 3.36 ± 0.01 to 6.81 ± 0.01, 2.48 ± 0.01 to 13.16 ± 0.01, with the control at 13.32 ± 0.01. Chromosomal aberrations, including chromosome break, fragmentation, bridge, vagrant, lesion, and sticky C-mitosis, were observed. These alterations indicated that toxic substances significantly impact DNA sequence.

Published: April 2024

An import permit is issued by the National Plant Protection Organization of each country, known in Nigeria as the Nigeria Agricultural Quarantine Service (NAQS), to allow the importation of pest-free plants and prevent the introduction of quarantine pests or check the entry of regulated non-quarantine pests of imported plant commodities. Issuance of import permits at the Post-Entry Quarantine, Surveillance and Diagnostic Station (PEQDS), Ibadan is mostly for germplasm materials mainly used for cultivation, which poses a high risk of pest introduction. Thus, this study investigated the statistical components of the issuance of import permits at the PEQDS using the Time Series approach to determine the peak period of collection essential for planning phytosanitary activities to mitigate the introduction of foreign pests. The dataset of the monthly issuance of import permits from January 2012 to July 2022 was analysed. From the preliminary study, we observed that the series exhibit seasonal and stationary components with no definite trend pattern, hence we modelled the series using a Seasonal Autoregressive Moving Average (SARIMA) model. Several models were estimated and the best model (SAR(12)) for forecasting the future import permit collectionwas selected based on the forecast accuracy measures. The forecasted values indicated the highest issuance of import permits in May and September, each year and showed a fluctuating movement over time in the future. To further prevent pest incursion and facilitate trade, NAQS needs to operate round-the-clock surveillance, keep its staff on high alert and adequate facilities operational for more effective activities. Other factors responsible for low and fluctuating issuance of import permits should also be investigated.

Authors: Asuzu-Samuel H. O. , Karibo A. O. 
Published: April 2024

The chronic hyperglycemia of diabetes is associated with long-term damage, dysfunction, and failure of various organs. Therefore, the objective of this paper was to assess the effects of wonderful kola (Buchholzia coriacea) on biochemical markers such as liver and kidney in alloxan induced diabetic Wistar rats using appropriate standard techniques. The result showed that Buchholzia coriacea seed extract caused significant (p<0.05) reduction in the levels of glucose. The liver function test revealed notable changes in the negative control group compared to the control group, including elevated levels of AST, ALT, ALP, and T.P (*p<0.05). Treatment with Metformin and the high dose of Wonderful Kola exhibited significant improvements in AST, ALT, and ALP levels compared to the negative control (#p<0.05), suggesting potential hepatoprotective effects. The kidney function test, revealed notable difference In comparison to the control group, the negative control group showed significantly (p<0.05) elevated levels of Urea, Creatinine, K, Na, Cl, T.B, and C.B. Treatment with Metformin demonstrated a significant (p<0.05) decrease in Urea and Creatinine levels compared to the negative control. The low and high doses of Wonderful Kola resulted in significant (p<0.05) reductions in Urea, Creatinine, and T.B levels, with the high dose also significantly decreasing Na and Cl levels compared to the negative control. The methanoic extract of Buchholzia coriacea seed possess hypoglycemic properties and may therefore be beneficial in the management of diabetes mellitus at the above dosage and treatment period. Buchholzia coriacea especially at high doses exhibited protective effects on the liver and kidney biochemical markers in alloxan induced diabetic rats, highlighting its potential as a therapeutic agent.

The edible jelly fungus Dacryopinax spathularia (Dacrymycetaceae) is wood-decaying and can be commonly found worldwide. It has found application in food additives, given its ability to synthesize long-chain glycolipids, among other uses. In this study, we present the genome assembly of D. spathularia using a combination of PacBio HiFi reads and Omni-C data. The genome size is 29.2 Mb. It has high sequence contiguity and completeness, with a scaffold N50 of 1.925 Mb and a 92.0% BUSCO score. A total of 11,510 protein-coding genes and 474.7 kb repeats (accounting for 1.62% of the genome) were predicted. The D. spathularia genome assembly generated in this study provides a valuable resource for understanding their ecology, such as their wood-decaying capability, their evolutionary relationships with other fungi, and their unique biology and applications in the food industry.

Chitons (Polyplacophora) are marine molluscs that can be found worldwide from cold waters to the tropics, and play important ecological roles in the environment. However, only two chiton genomes have been sequenced to date. The chiton Liolophura japonica (Lischke, 1873) is one of the most abundant polyplacophorans found throughout East Asia. Our PacBio HiFi reads and Omni-C sequencing data resulted in a high-quality near chromosome-level genome assembly of ∼609 Mb with a scaffold N50 length of 37.34 Mb (96.1% BUSCO). A total of 28,233 genes were predicted, including 28,010 protein-coding ones. The repeat content (27.89%) was similar to that of other Chitonidae species and approximately three times lower than that of the Hanleyidae chiton genome. The genomic resources provided by this work will help to expand our understanding of the evolution of molluscs and the ecological adaptation of chitons.

Debido a la potencia y la velocidad, la patada es el gesto técnico más utilizado en el Taekwondo para la obtención de un punto. Por ello, la fuerza explosiva y las variables relacionadas son de interés para el control del entrenamiento y la mejora del gesto técnico. El objetivo de este estudio fue conocer la asociación entre la potencia desarrollada en el SJ, el CMJ y la potencia aplicada en las técnicas de patada: Bandal Chagi, Yeop Chagi. En el estudio cuantitativo, transversal con alcance correlacional, participaron 12 atletas a quienes se les midió 7 variables relacionadas a la potencia en la ejecución del SJ y el CMJ. Así mismo, se determinó la potencia de las patadas mediante el Sistema Electrónico de Puntuación de Protección (PSS). De las correlaciones identificadas entre las patadas y los saltos (SJ, CMJ), la patada Bandal Chagui se asoció con una mayor cantidad de variables medidas en el CMJ y en menor medida con el SJ; las correlaciones tanto para el CMJ y el SJ fueron menos en la patada Yeop Chagu. Por lo que se concluye en la especificidad del CMJ en la evaluación de los factores determinantes en el rendimiento del mencionado gesto técnico, no así del SJ.

Abstrat. Due to its power and speed, the kick is the most used technical gesture in Taekwondo to obtain a point. Therefore, explosive strength and related variables are of interest for training control and improving technical gestures. The objective of this study was to determine the association between the power developed in the SJ and the CMJ and the power applied in the kicking techniques: Bandal Chagi and Yeop Chagi. In the quantitative, cross-sectional study with a correlational scope, 12 athletes participated, of whom 7 variables related to power in the execution of the SJ and CMJ were measured. Likewise, the power of the kicks was determined using the Electronic Protection Scoring System (PSS). Of the correlations identified between kicks and jumps (SJ, CMJ), the Bandal Chagui kick was associated with a greater number of variables measured in the CMJ and, to a lesser extent, with the SJ; the correlations for both the CMJ and the SJ were less in the Yeop Chagu kick. Therefore, it is concluded that the CMJ is specific in the evaluation of the determining factors in the performance of the aforementioned technical gesture, but not the SJ.
