Вступ. Даний огляд присвячений аналізу рівнів поширення тромбу у нижній порожнистій вені та його вплив на прогноз виживаності при раку нирки з метастатичним тромбозом НПВ.
Мета. Проаналізувати в оглядовій статті вплив на прогноз рівня ураження нижньої порожнистої вени (НПВ) при нирково-клітинній карциномі (НКК) та дослідити сучасні принципи лікування НКК з пухлинним тромбозом НПВ.
Матеріали і методи. Проведено літературний пошук та проаналізовано відповідні статті. Відносно недавні роботи, а також великі серії або роботи з експертних центрів включені до списку літератури.
Результати та їх обговорення. Пухлинний венозний тромбоз при НКК є серйозною та частою проблемою сьогодення, пацієнти з такою патологією мають поганий прогноз. Хоча успішне видалення пухлинного тромбу в нирковій вені та нижній порожнистій вені може призвести до покращення довгострокового виживання у більш ніж половини пацієнтів, проте високий рівень тромбу є поганим прогностичним фак- тором рецидиву раку. Повна тромбектомія нижньої порожнистої вени, навіть за наявності метастазів, забезпечує кращу якість життя і може подовжити виживаність.
Висновки. Хірургічне втручання – найефективніший метод лікування пацієнтів з нирково-клітинною карциномою. Необхідно докладати всіх зусиль для повного видалення тромбу з нижньої порожнистої вени. Нова таргетна (прицільна) терапія може бути перспективною в якості допоміжної терапії у цієї підгрупи пацієнтів.

Authors: Fondevila-Suárez Eduardo , Velasco Enrique , Escamilla Ugarte Rafael , Flores-Cortés Mar , Pinteño Álvaro , Tovar-Ochovo Rubén 
Published: January 2024

Objetivos: Si el dolor es una sensación (relacionado con perturbaciones corporales) o una percepción (relacionado con las diferentes evaluaciones del paciente) es una pregunta que, en principio, la Fisioterapia no tiene la responsabilidad de responder, como tampoco lo es resolver el problema de la consciencia. Sin embargo, el dolor es un fenómeno consciente y esto tiene unas implicaciones científicas y clínicas importantes que no podemos seguir soslayando durante más tiempo, ni en la consulta ni en el laboratorio. Nos preguntamos entonces qué luz puede arrojar el estudio de las Teorías de la Consciencia y del dolor para aproximarnos al problema real del paciente con dolor de una manera rigurosa y ética.
Métodos: Se realizó una revisión crítica de la neurociencia de la consciencia y del dolor y de la filosofía de la mente y del dolor, tomando la estructura del superventas Being You: A new science of consciousness (Seth, 2021), en relación con el marco teórico de la Fisioterapia y su aplicación en la práctica clínica y la investigación.
Resultados: La HOT se relaciona con el evaluativismo y la Educación en Neurociencia del Dolor. El imperativismo y la Teoría Corporal guardan relación con la GNWT. Desde la IIT se propone un marco de tipo pluralista para disolver las aporías y paradojas que se presentan en el campo del dolor, así como para delimitar el alcance de nuestras intervenciones.
Conclusiones: Con el cuerpo de conocimiento actual, científico y filosófico, no se puede estudiar seriamente el dolor dejando de lado sistemáticamente el asunto de la consciencia. Las Teorías de la Consciencia, desde una perspectiva pluralista, pueden arrojar luz sobre problemas acuciantes en el campo, tanto a nivel clínico como investigador. Quizá no para obtener respuestas, pero sin duda para ayudar plantear las preguntas correctas.
Pointwise hemi-slant Riemannian submersions
Authors: Akyol Mehmet Akif , Sayar Cem 
Published: January 2024

UDC 517.98
We introduce a new type of submersions, which is called <em>pointwise hemi-slant Riemannian submersions,</em> as a generalization of slant Riemannian submersions, hemi-slant submersions, and pointwise slant submersions from Kaehler manifolds onto Riemannian manifolds. We obtain some geometric interpretations of this kind of submersions with respect to the total manifold, the base manifold, and the fibers. Moreover, we present non-trivial illustrative examples in order to demonstrate the existence of submersions of this kind. Finally, we obtain some curvature equalities and inequalities with respect to a certain basis.

Published: January 2024

UDC 517.9
This paper is essentially motivated by the demonstrated potential for applications of the presented results in numerous widespread research areas, such as the mathematical, physical, engineering, and statistical sciences. The main object here is to introduce and investigate a class of fractional integral operators involving a certain general family of multiindex Mittag-Leffler functions in their kernel. Among other results obtained in the paper, we establish several interesting expressions for the composition of well-known fractional integral and fractional derivative operators, such as (e.g.) the Riemann–Liouville fractional integral and fractional derivative operators, the Hilfer fractional derivative operator, and the above-mentioned fractional integral operator involving the general family of multiindex Mittag-Leffler functions in its kernel. Our main result is a generalization of the results obtained in earlier investigations on this subject. We also present some potentially useful integral representations for the product of two members of the general family of multiindex Mittag-Leffler functions in terms of the well-known Fox–Wright hypergeometric function

A modulus of smoothness for some Banach function spaces
Authors: Akgün Ramazan 
Published: January 2024

UDC 517.5
Based on the Steklov operator, we consider a modulus of smoothness of functions in some Banach function spaces, which can be not translation invariant and establish its main properties. A constructive characterization of the Lipschitz class is obtained by using the Jackson-type direct theorem and inverse theorem of trigonometric approximation. As application, we present several examples of related (weighted) function spaces.

Published: January 2024

Economic feasibility is one of the major criteria for selecting energy options for application in any location. One of the main drawbacks of renewable energy technology is its initial cost of investment which results in high energy tariffs making it unaffordable for low-income earners. The cost of renewable energy depends on many factors such as the potential of the renewable resources of the site and government policies on renewable energy technology. This paper aimed to determine the annualized cost of a designed hybrid solar-wind power system for the Heipang community to meet a load demand of 158.3kW and the sensitivity analysis of bank loan interest rate, inflation rate, day of autonomy, depth of battery discharge, and wind turbine rated velocity on the investment payback time. The cost of the components of the designed system was obtained from vendors and a techno-economic analysis was done using MATLAB software. Results show that the annualized cost of the hybrid solar-wind power system is ₦ 52,268,266.97, with battery, solar, and wind power systems taking 85%, 8%, and 7% of the total annualized cost respectively, and Levelized cost of energy ₦ 154.53/kWh. The analysis further shows that for ₦ 185.00, N 160.00, and ₦ 127.00 per kWh cost of energy at a 19% inflation rate and 20% bank interest rate, the investment payback times are 8.3, 9.5 and 11.9 years respectively, and 9.8, 11.4 and 14.3 years respectively. Information from this work may help policy-makers and would-be investors make informed decisions on renewable energy technology investment.

Lineament characterization and their tectonic significance in mineralization using Landsat TM data and field studies Along the Mambilla Plateau and environs, northeast Nigeria .The area forms part of the mineralized shear zone of the Northeastern, part of the Basement Complex. The Basement Complex rocks underlie more than two-thirds of the plateau and date back to the Precambrian to early Paleozoic eras. While the remaining part of the plateau and its surroundings are made up of volcanic rocks of the upper Cenozoic to Tertiary and Quaternary ages. Remote sensing imagery data and field measurements were integrated for mapping the structural elements and hydrothermal alteration zones related to mineralization. Tectonically the lineaments trends NE-SW, NNW-SSE, NW-SE, and NS, are the main trends controlling mineralization in the area based on data from remote sensing and field measurements. On the other hand, applying band ratios and the constrained energy minimization (CEM) technique to Landsat-8 data pointed out alteration minerals associated with the hydrothermal fluids. Silica, sericite, and chlorite are the common alteration minerals detected, while goethite and epidote are less common in the alteration zones of the area under study. A combination of CET structural complexity, circular features, and alteration zones produced a potential mineralization map, pointing out numerous prospective zones for mineralization that are proximate to areas where artisanal mining activities are carried out. The predictive map was validated by projecting the known prospect zones in the study area, reflecting an agreement between the known occurrences and the higher classes of the predictive zone. The techniques in the current research can be adopted as a direct indicator for structural mapping and detecting alteration zones related to mineralization elsewhere.
Evaluation of the potentials of <i>Pennisetium glaucum</i> and <i>Vigna unguiculata</i> for phytoremediation of Spent-engine oil contaminated soil

Published: January 2024

One promising technique for cleaning up soil polluted by spent engine oil is phytoremediation. Particularly in the tropics, where resources can be scarce and the climate is favorable for plant development. Finding plant species that will work well with this technology was the aim of this investigation. The ability of a cereal (Pennisetum glaucum) and a legume (Vigna unguiculata) to remediate soil contaminated with 1%, 2%, 3%, 4%, and 5% (W/V) of spent engine oil was evaluated. After 150 days of incubation, the Total Petroleum Hydrocarbon (TPH) loss in greenhouse studies was calculated. The total petroleum hydrocarbon content of soil that was vegetated with P. glaucum and V. unguiculata was substantially lower than that of non-vegetated soil. Furthermore, a positive association was discovered between the initial TPH and the total petroleum hydrocarbon loss caused by planting P. glaucum. It was also discovered that P. glaucum outperformed V. unguiculata in remediation capacity. These findings suggest that P. glaucum be investigated further, which might lead to a better understanding of how to apply phytoremediation to soils contaminated with spent-engine oil.

Published: January 2024

Malaria in pregnant women remains a major public health problem especially in sub-Saharan Africa. Approximately twenty five million pregnant women in sub-Saharan Africa live at risk of malaria. The study was carried out between July and August 2021, to determine the prevalence of malaria parasite among pregnant women attending Mohammad Abdullahi Wase Teaching Hospital Kano. Microscopic examinations of both thick and thin smears were made using Giemsa Stained solution. Out of one hundred and forty blood samples examined, 60(42.9%) were positive for plasmodium falciparum parasite infection. Age group 18-22 years recorded the highest prevalence rate of (17.90%) and the difference between the age group of the pregnant women was statistically significant (P<0.05) .Primigravida women recorded highest infection rate (23.60%). However, those in first trimester recorded the highest prevalence of (25%) followed by those in the second trimester (13.57%). These results show that pregnant women are more predisposed to malaria infection as they are immunosuppressed especially at early stage and as a primigravida and as teenage mothers than multigravida and older mothers. The problem of P. falciparum in pregnant women can be prevented by the preventive package of intermittent preventive treatment (IPT) with sulfadoxine pyrimethamine (SP) at 2 doses given to the pregnant women during their antenatal clinical visits. During this study, the prevalence of malaria infection among pregnant women attending Muhammad Abdullahi Wase Teaching Hospital was notably higher. P. falciparum is the most common Plasmodium parasite in this region therefore, more special attention should be directed towards pregnant women who exhibit identified risk factors for malaria infection.

The potential health benefits of turmeric have often been overlooked, but recent research is beginning to suggest that the active ingredient found in the Turmeric, plays an important role in improving insulin resistance and metabolic disorders. Curcumin has been found to possess some remarkable medicinal properties and has wide-ranging biological activities that can help ameliorate the symptoms associated with these disorders. In this review, the positive effects of curcumin on the prevalent metabolic disorder known as diabetes would be examined. Many recent studies have shown the positive effects of this spice and the benefits to patients suffering from this disease. Curcumin has been reported extensively revealing that it improves insulin sensitivity and lowers the levels of glucose in the blood. It also possesses antioxidant properties which have been attributed to the reduction in inflammation and protection of body cells as well. The different bioactive ingredients present in curcumin, their healing characteristics and their applications in medicine as a result of this healing constituent will also be highlighted in this review.

Published: January 2024

The use of relevant information from auxiliary variables at the estimation stage and design stage to obtain reliable and efficient estimates is a common practice in a sample survey. Several Estimators of population variance have been suggested. However, these estimators do not consider the situation of non-response due to non-availability of respondents, refusal to respond, presence of hard- core respondents or due to non-understanding of the question thereby, reducing the efficiency of the estimators and the parameters of the auxiliary variable X̄ , S2x used are sensitive to outliers or extreme values which can either lead to underestimation or overestimation. To address the aforementioned observations, classes of variance estimators under the simultaneous influence of non-response and measurement errors using outlier-free parameters as well as calibration approaches were proposed. The properties (Bias and MSE) of the modified estimators were derived up to the first order of approximation using the Taylor series approach. The efficiency conditions of the proposed estimators over the existing estimators considered in the study were established. The empirical studies were conducted using simulation and the results revealed that the proposed class of estimators have minimum MSEs and higher PREs among all the competing estimators. These imply that the proposed estimators are more efficient and can produce a better estimate of the population mean compared to other existing estimators considered in the study.

Published: January 2024

A field trial was carried out during the 2022 rainy season at the National Horticultural Research Institute Bagauda substation (NIHORT) situated in the Sudan savannah ecological zone of Nigeria (190 4̍ N, long 120 26' E, and 721m above sea level). The trial was done to investigate cutting heights response on the proximate composition analysis of Amaranthus cruentus. The treatments consisted of three cutting heights (10cm, 15cm and 20cm) and laid out in a randomized complete block design with three replications. Fresh samples were oven dried and grounded into powder using blender and passed through 2mm sieve. which were determined using standard procedure by AOAC method and analyzed for proximate composition.There were significant effects in the results obtained on the percentage of fat and crude fibre only.Percentage of protein, moisture, carbohydrate, nitrogen, phosphorous and potassium were found to be non- significant. These findings suggest that cutting amaranth shoots at 20cm above the ground has an increased effect on means of percentage fat (3.062) and crude fibre (3.80) containing nutrients that has great potential for mechanical harvesting that may improve the nutritional components of the crop.

Published: January 2024

Integrated geophysical investigation on the Mambilla Plateau and its environs was necessary to map the locations of basaltic intrusions and their patterns of distribution. The Landsat-8 ETM+ false colour composite image (bands 7, 4, 2 in R, G, and B) was used to identify rocks such as younger basalt (yb), porphyritic granite (pg), granite gneiss (Gn), and migmatite gneiss (Mg). Similarly, rocks like granite gneiss (Mg), porphyritic granite (pg), and migmatite gneiss (Mg) were recognised by the Principal Component Analysis of the Landsat 8 ETM+ picture (PC2, PC1, and PC4 in R, G, and B). The lowest and maximum values for the total magnetic intensity map were 33030.343 nT and 33172.792 nT, respectively, along with mean of value 31.50nT to 33068.89nT.The primary magnetic field map showed an average value of 33293.4495 nT, with values ranging from 33228.522nT to 33358.377nT. The crustal magnetic field map resulting from ore bodies or intrusions had an average value of -159.50 nT, with values ranging from -397.669 nT to -80.699 nT. The RTE values, which range from -82.382nT to -392.122nT, indicate regional geological intrusions, fractures, and faults. Values were shown on the magnetic equator field map, which was further upward continued to 15 km, with an average values ranging from -279.141nT to -157.160nT. The pseudo-gravity map of the region showed two low densities, ranging from -0.11 to -0.01 mGal, depending on the location, and three high densities, indicating moderate to intermediate densities, ranging from 0.25 mGal to 0.01 mGal. RTE anomaly data produced from subsurface rocks typically has the greatest horizontal gradient along the object's border. This means that the maximum gradient is directly localised to the map boundaries of the distinct lithologies. By examination of the abrupt changes in rock magnetism in a lateral direction, this led to the determination of contact limits of the basaltic intrusion, faults, and mineralization of the underlying rocks
