OBJECTIVE
A taxonomy for superficial cerebral cavernous malformations (CMs), those based cortically in gyral gray matter or subcortically in underlying white matter, is proposed to build on the comprehensive, systematic characterization of CMs in the entire brain.

METHODS
Patients with superficial cerebral CMs were retrospectively analyzed from a consecutive surgical series between November 2008 and June 2021 at the authors’ center. Superficial cerebral CMs were categorized into 4 subtypes based on their cortical location or, if subcortical, proximity to the nearest cerebral surface: convexity, medial, basal, and sylvian. Lobar location was also included for subtyping: frontal, temporal, parietal, and occipital.

RESULTS
A total of 362 CMs were resected in 346 patients. CM subtypes were as follows: 132 (36.5%) convexity, 78 (21.5%) medial, 72 (19.9%) basal, and 80 (22.1%) sylvian. Frontal CMs were most common (155 [42.8%]), followed by parietal (89 [24.6%]), temporal (87 [24.0%]), and occipital (31 [8.6%]). Of all CMs, 302 (83.4%) were cortical and 60 (16.6%) were subcortical. The mean subcortical depth of deep lesions was 2.97 cm, and the mean lesion volume was 4.68 cm3. Overall, 228 lesions (63.0%) were resected through a transgyral approach, and 134 (37.0%) were resected through a transsulcal approach. Good outcomes (modified Rankin Scale [mRS] score ≤ 2) were observed in 314 patients (86.7%) and poor outcomes (mRS score > 2) in 25 patients (6.9%), and 23 patients (6.4%) were lost to late follow-up (mean follow-up duration 11.5 months). Relative outcomes were good (unchanged or improved mRS score) in 327 patients (90.3%) and poor (worse or died) in 35 patients (9.7%).

CONCLUSIONS
Superficial cerebral CMs were resected through a gyrus or sulcus to open the subarachnoid dissection corridors, traversing the full extent of sulci to deepen the approach and minimize tissue transgression. Transgyral dissection avoids associated arteries but is inherently transgressive, whereas transsulcal dissection preserves cortical tissue and may reduce morbidity. Superficial cerebral CMs occupy the largest territory of the 7 types, and the size and surface complexity of the cerebrum make taxonomic subtyping valuable for clear anatomical description.

Discus fish have developed rapidly among ornamental fish enthusiasts, both on a small scale and in the ornamental fish industry and have a critical point for fish larvae in the form of a transitional phase from the period of care by the parents to the stage of separation from the parents, due to their habit of eating the mucus produced by the parents as the main food for the fish larvae. The nutritional needs of discus fish larvae must be met to support the growth and success of this fish farming by meeting the nutritional needs of fish larvae using natural food. Moina sp. is one of the natural feeds that can be used in the rearing period of discus fish larvae, and it can be improved the quality by enrichment method using HUFA and ascorbic acid because it was the most important nutrient elements in feed which affects growth and survival. The purpose of this study was to determine the combination of doses of Moina sp. natural feed enrichment.

This study aims to determine the effect of Nitrogen-inhibiting bacteria and chicken manure (cohe) fertilizer on soybean yield. The research method used a 2 factorial Randomized Group Design. The first factor was the treatment of rhizobium biofertilizer (R) consisting of 4 levels, namely R0 = 0 g/kg seed, R1 = 5 g/kg seed, R2 = 10 g/kg seed, and R3 = 15 g/kg seed. The second factor is the treatment of chicken cohe fertilizer (S) consisting of 4 levels, namely S0 = 0 kg/m2, S1 = 0.5 kg/m2, S2 = 1.0 kg/m2, and S3 = 1.5 kg/m2. The results showed that the provision of rhizobium biofertilizer 10 g/kg seed had a real effect on the number of soybean pods, dry weight of seeds per plant, dry weight of 100 seeds, with the highest number of pods 1169.03 g, the highest dry weight of seeds 388.56 g, the highest weight of 100 seeds 15.88 g. Application of chicken cohe fertilizer 1.5 kg/m2 on the soil had a real effect on the number of pods, dry weight of seeds per plant, dry weight of 100 seeds, with the highest number of pods 167.25 g, dry weight of seeds 393.86 g and the highest weight of 100 seeds 16.50 g. The interaction of rhizobium biofertilizer and chicken cohe fertilizer was not significantly different in all treatments.

Published: January 2024

Using a quantitative longitudinal trends analysis, this study analysed the link between tax evasion and avoidance. The main aim was to assess the implications of evasion and avoidance of taxes on South African economy progress from 1994-2021. Publically secondary data available from South African Revenue authority were gathered. The data gathered provided us with basis of longitudinal statistical analysis of the extent of tax evasion and or tax avoidance affected the economic growth in the years 1994-2021. The Eviews 10 Results was used to estimate elasticities and buoyancies for major taxes with respect of South Africa’s economic growth for years 1994-2021. The natural logarithm of the gap between total budgeted tax income and realised tax income was also employed as a metric of tax evasion and avoidance in South Africa for this key research work. Ordinary Least Squares Regression (OLS) regression analysis was employed to evaluate whether the link between Gross Domestic Product (GDP) and tax evaded and avoided is strong or weak. Test for stationarity to see whether the parameter does not vary over time and for OLS was performed. The overall analysis of tax evasion and avoidance upon South African economy showed the increased tax revenue resulted in surpluses between tax revenue budgeted, tax revenue collected and economic growth (GDP), meaning tax evasion and avoidance in South Africa are minimal. The study's findings disprove prior studies that suggest that tax evasion and tax avoidance seriously affect Gross Domestic Products (GDP) and refute the null hypothesis of this study. However, the study’s results further revealed that increasing tax rates was said to have triggered a positive trend towards economic growth or GDP (actual revenue collected is more than expected taxation revenue annually to cover tax evaded and avoided. As far as policy is concerned the conclusion is reassuring that tax evasion and avoidance has minimal effect upon economic growth as long as tax rates are being risen. The results of this study provide implications for government that specific insights should allow policy makers to gain a better understanding on the key variables that are potentially associated with tax evasion and avoidance. Finally, the study contributes knowledge that is pertinent to an emerging country and provides much needed insights into the magnitude of the extent of tax evasion and avoidance on the county’s economic growth progress.
Examining Monetary Policy Cyclicality in Egypt during Crisis Time: Global Financial Crisis versus COVID-19 Pandemic
Authors: Emam Hebatalla Atef 
Published: January 2024

Egypt has been exposed to two recent shocks: the global financial crisis of 2008 and the COVID-19 Pandemic of 2020. Though the origin and the implications of the two shocks are quite different, they bear some similarities in terms of the sharp decline in global economic growth and negative implication on the Egyptian economy. The present study attempts to assess the cyclicality of monetary policy in Egypt during the two crises. To this end, both descriptive and econometric techniques are employed in this study to reveal the cyclicality of monetary policy. On the descriptive side, the correlation between the cyclical component of policy rate and that of real GDP is calculated. Moreover, both an ARDL and NARDL approach are estimated to derive the augmented Taylor rule for the cyclical component of policy rate. Two dummy variables reflecting the two crises along with their interaction with output gap are incorporated in the model to disentangle the impact of the two crises upon monetary policy cyclicality. The study concludes that monetary policy in Egypt is more acyclical and that its response to changes in output gap is statistically insignificant, during both normal times and crisis time.

Published: January 2024

This study aims to perform a quantitative analysis of the portrayal of gender in the nursing textbook used at the University of Buraimi in Oman. The study sought to examine gender-related categories, such as images, names, pronouns, words of address, and jobs, through the use of quantitative content analysis. The study findings suggest that, to some extent the nursing textbook exhibits a state of gender equilibrium and parity. The textbook displayed females as more visible than males in images and job categories. In contrast, males were more prominent in domains related to names, pronouns, and forms of address. In general, the school textbook exhibited a fair and impartial representation of both genders to a certain degree. The findings of this current research article are anticipated to assist authors in developing instructional materials that demonstrate a more balanced portrayal of genders within the curriculum.

Introducción: Los trastornos vesiculares en el embarazo se consideran en la actualidad una de las patologías abdominales no obstétricas más comunes, siendo un problema de salud pública. La presencia de cálculos biliares es más frecuente en mujeres embarazadas que en las no gestantes, debido a los cambios fisiológicos y hormonales que experimenta la mujer en esta etapa, lo cual predispone a la aparición de patologías vesiculares, afectando el trascurso normal del embarazo. La demora en el manejo de estas enfermedades implica un aumento en la morbilidad de este grupo poblacional. Objetivo: Analizar las pautas y recomendaciones actuales sobre el manejo terapéutico de los trastornos vesiculares en gestantes. Metodología: Investigación bibliográfica con enfoque cualitativo de alcance descriptivo con investigaciones publicadas en los últimos 5 años; fueron revisados 35 documentos con validez científica obtenidos de bases de datos regionales y de alto impacto en inglés y español. Resultados: Existe una controversia en la elección del tratamiento, hay diversas opciones terapéuticas entre ellos el manejo conservador y el abordaje quirúrgico. La colecistectomía laparoscópica es beneficiosa y segura en cualquier trimestre de la gestación con tasas bajas de complicaciones materno-fetales de un 3.5%. Conclusión: La colecistectomía laparoscópica es un método seguro y de elección para aquellas pacientes con sintomatología y/o complicaciones de patología biliar, mientras que el enfoque conservador se reserva para pacientes asintomáticas.

Repellent activity of essential oils extracted from the leaves of Otostegia integrifolia and Stephania abyssinica, roots of Echinops kebericho and seeds of Millettia ferruginea and Datura stramonium were tested against malaria vector, Anopheles arabienses. The repellent activity was determined at 125, 250, 500 and 1000 ppm concentration by human volunteer. The dorsal side of each human arm 153.86 cm2 of the skin was exposed for twenty minutes by covering the remaining area with rubber glove. The control and treated arm were introduced simultaneously into mosquito cage under laboratory condition maintained at 27 +/- 1°C, 65-70% RH. Among the four different concentrations tested, maximum repellent activity was observed at 1000 ppm of O. integrifolia, S. Abyssinica and M. ferruginea and also E. kebericho has strong repellent properties in all concentrations. O. integrifolia, S. abyssinica, M. ferruginea and E. kebericho may contain repellent chemicals which can be used for the development of safer mosquito repellent product.
