Published: November 2024

A crucial impact of climate change is the disruption of the agricultural sector, posing a threat to food supply for the globally increasing population. In this context, prioritizing food security in each country becomes an important concern. This study aimed to explore biomass and C-Stock content of Sago forests for handling climate change and resilience. The methodology used comprised various steps including determining the type and the hydraulic conductivity of the soil, assessing biomass and C-Stock by cutting Sago at various growth stages, weighing the wet and dry weight of each fraction, calculating the Top-Root Ratio, and determining the starch yield. The results showed that there were four types of soil namely Hydric, District, and Fluvic Gleisol, as well as Oxic Cambisole. C-Stock was 26.99 tonnes per hectare with a Top-Root Ratio of 636%, implying that above-ground biomass (AGB) was six times more than below-ground biomass (BGB) and the presence of mineral soil. Sago dry starch product ranged from 490.3–571.8 kg per tree and the potential relatively varied due to differences in the structure and composition of forests, as well as habitat and environment. Although logging remained persistent on a very small scale, early signs of disturbances were observed in hydrological conditions and fluctuations in water levels or puddles in the soil profile. This implied that conversion of Sago forests to other uses for the expansion of grain crops on a large scale, would lead to the area experiencing drought.

A clinical case of dural arteriovenous fistula (DAVF) of the tentorium cerebelli: a challenging diagnosis and treatment of a patient with a DAVF of the tentorium cerebelli is presented. The rapid onset of the disease in patient M. in September 2023 and the progression of the neurological deficit led to a preliminary diagnosis of «brainstem autoimmune encephalitis». The further development of symptoms and data from additional diagnostic methods made it possible to suspect acute transverse cervical myelitis at the C1—C6 level, with spread to the medulla oblongata, most likely associated with a viral infection. The prescribed treatment was ineffective. The appearance of new symptoms in December 2023 and the analysis of repeated MRI scans of the brain and spinal cord suggested a spinal DAVF, which required differentiation from a mass lesion. DAVF is a vascular anomaly in which arteries, arising from branches of the carotid or vertebral arteries, flow directly into the sheets of the dura mater surrounding the venous sinuses. After selective spinal angiography, the patient was diagnosed with a DAVF in the area of the tentorium cerebelli, supplied by the meningeal branch of the cavernous part of the left internal carotid artery, with drainage into the venous plexus of the spinal cord. At the State Institution «Scientific and Practical Center for Endovascular Neuroradiology of the National Academy of Medical Sciences of Ukraine», an operative intervention was performed — endovascular disconnection of the dural arteriovenous fistula. Embolization was performed in «flow» with balloon assistance to prevent retrograde migration of the embolic agent. Angiographically, complete separation of the fistula was achieved. In April 2024, control angiography revealed filling of the fistula from small meningeal anastomoses of the territory of the meningeal branches of the left ICA. Microsurgical treatment was then performed to achieve total disconnection of the fistula. After surgery, the patient’s condition stabilized.

This study aims to identify students' ability in writing short stories after participating in learning with the Problem-Centered Learning (PCL) model, as well as to analyze the difficulties they face and the obstacles faced by teachers in implementing PCL. This study applied a qualitative case study approach at SDN 112/IX Muhajirin, involving 17 students of fourth grade and one teacher. Data were collected through observation, assessment of student writing content, and interviews, then analyzed descriptively and thematically. The results showed that PCL had a positive impact on improving students' ability in writing short stories by developing clear themes, deep characters, and effective storylines. However, students faced difficulties in developing the author's background and adapting the language style. Teachers also faced challenges in technical readiness and institutional support. Based on these findings, it can be concluded that PCL is effective in improving elementary school students' short story writing skills despite facing implementation challenges. The need of additional support for the development of teaching strategies and in-depth training for teachers to overcome these difficulties is emphasized.

ABSTRACT
Objective: Oreochromis niloticus (Tilapia) meal was evaluated as a source of nutrients in agriculture, through a composting process mixed with a zero tillage soil.
Design/methodology/approach: Two manures were formulated, mixing flour and soil at a 30:70 ratio (mass/mass w:w) respectively. Compost A was maintained at 60 days of composting (ddc), compost B at 30 days. The phytotoxicity of the manures was evaluated as percentage of germination in Solanum lycopersicum (tomato) seeds.
Results: The N-P-K ratio (% dry mass) was 1.90-2.06-0.30 for manure A (60 ddc), and 2.60-2.24-0.34 for B (30 ddc). On germination, 100% concentration; manure A had 44.9% and B 19.6%, compared to the control. For concentration of 10% it was 93.7 and 111.4%, manure A and B, respectively.
Limitations on study/implications: It is necessary to carry out more phytotoxicity tests. In this experiment, dilutions were made in the manures to increase germination.
Findings/conclusions: The use of manure based on tilapia meal in agriculture is proposed in the future and in this way take advantage of the waste from fish processing.

Published: November 2024

Human activities and natural events continually reshape land use patterns, underscoring the critical need for accurate land use information in various applications such as natural resource management and environmental monitoring. Land use change has become pivotal in current strategies for these purposes globally. The rapid advancements in land use mapping have spurred increased studies worldwide, aiming to assess and monitor the extent and health of forests, grasslands, and agricultural lands. Remotely sensed data, including aerial photographs and satellite imagery, are indispensable for extracting precise land use change information. This study focusing on Manga grassland (Machina, Yusufari, and Yunusari LGAs), satellite images from Landsat TM (1988), Landsat ETM (1998), Landsat ETM+ (2008), and Landsat 8 (2018) for image classification. The study employed supervised classification methods to analyse land use changes, revealing significant alterations in vegetation cover over the study period. In conclusion, it was observed that observed that vegetation cover increases from north toward the south follow the trend of rain fall, over-cutting, over grazing, and other climatic factors, which determines species distribution. Vegetation degradation is detected more in north boundary Niger republic. This may be due to southern flow of the Sahara Desert into the northern part of Nigeria around the study area. Data analysis shows that land use land cover had been changing through the study zones and this change had negative impact on natural resource development. Finally, it was recommended that the development of suitable and adequate mean of awareness for local community on the importance of species...

Published: November 2024

The study explored present and future climate scenarios of Kano using Global Circulation Models (GCMs). The metrological data from 12 locations were used for calibration of Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS). The historical record of 10 years was used for both temperatures and rainfall data which represent a period of 2010 to 2019. The future climate projections were made for 2041 to 2060 centered in the 2050s under RCP2.6 and RCP8.5 emission scenarios. The spatial analysis was conducted using the Inverse Distance Weighted (IDW) tool in an ArcGIS environment. The result shows that the temperature of Kano has increased relative to baseline condition by 1.025oC (2.45%) and 4.6 oC (10.98%) under RCP2.6 and RCP8.5 scenarios respectively. However, the annual rainfall was found to decrease from the historical amount by -37.9 mm (5%), and -68.2 mm (9%) under RCP2.6 and RCP8.5 emission scenarios. Moreover, the spatial analysis indicated that there was climate variability across the width and breadth of the state. The study concludes that the climate change effect will cause the temperature of Kano to rise considerably in the future with the consequences of decreased rainfall amount. The findings recommend that policymakers should deploy adaptation strategies to reduce the adverse effects that might be experienced.

Objective. Improving the effectiveness of treatment of patients with TMJ PDS myogenic origin. Material and methods. According to the purpose of the study, a group of 10 patients (8 women and 2 men aged 14 to 60 years) was formed with the coincidence of a triad of signs: pain during movements of the lower jaw, a feeling of heaviness and tension in the chewing and facial muscles, restriction of mouth opening. A set of diagnostic measures has been implemented in the following scope: clinical and radiological examination methods, TMJ MRI, ultrasound and surface EMG of the chewing muscles, digital axiography. In the treatment of patients in the study group, the method of invasive carboxytherapy was used, based on dosed injections of CO2 in the projection of trigger points of the masticatory muscles. The research examines the therapeutic value of using of CO2 in the protocol of functional rehabilitation of patients with TMJ diseases of myogenic origin. Results. The analysis of the effectiveness of treatment of patients in the study group was carried out to assess the dynamics of key parameters: the severity of the pain syndrome according to VAS, the magnitude of the IMPACT index values and the magnitude of mouth opening. The severity of pain in patients in the study group, according to average values, decreased by 86% from the initial values, an increase in the amplitude of mouth opening by 28.5%, a decrease in the IMPACT index values by 42.5% from the initial values of hypertonicity of the masticatory muscles, an increase in blood flow speed of superficial temporal artery at 52.5%. Conclusion. The results of the clinical application of the carboxytherapy method in the treatment of patients with TMJ PDS allow us to recommend this method for implementation in the rehabilitation protocols of patients with TMJ PDS of myogenic origin, trismus and hypertonus of the masticatory muscles. Carboxytherapy as a method of etiopathogenetic rehabilitation contributes to the early relief of pain syndrome, normalization of the bioelectric activity of the chewing muscles and restoration the physiological kinematics of the lower jaw’s movements.

Relevance. Traumatic prosthodontic stomatitis is the most frequent in clinical prosthetic dentistry, increasing the effectiveness of prevention and treatment of which is considered an urgent problem of practical dentistry. Objective. To study the effectiveness of using various domestic means for oral care in patients suffering from traumatic prosthetic stomatitis. Materials and methods. The study involved 42 elderly patients suffering from denture stomatitis due to the use of removable acrylic dentures. The patients were divided into 2 groups. In the control group after dentures correction they were recommended to use rinses and irrigations of the oral cavity with antiseptic solutions for a week, and later with infusions of medicinal herbs. Patients of the main group during their follow-up used local anti-inflammatory and wound-healing agents produced by thedomestic industry, as well as those improving the fixation of removable dentures. The effectiveness of denture stomatitis treatment and prevention of recurrence was evaluated on the basis of the patient’s complaints and clinical condition of the oral mucosa. Results. . It was established that for effective therapy of denture stomatitis it is necessary to use specially produced anti-inflammatory agents for the oral cavity during the period of acute inflammatory changes in the mucous membrane of the denture bed, and when using removable acrylic dentures it is necessary to recommend ASEPTA denture fixation cream, which has proved itself not only in the aspect of optimization of microbiota and mucosal immunity of the mouth, but also for optimization of psychophysiological state of patients. Their use makes it possible to achieve 81.47% efficacy of prosthetic stomatitis treatment on the 5th day and 100% efficacy of therapy on the 7th day from the beginning of their use by the patient, as well as in the nearest period to provide prevention of this disease recurrence. Conclusion. For secondary prophylaxis of traumatic prosthetic stomatitis, which occurs most often among the complications when patients use removable acrylic dentures, it is advisable to use specially produced by the domestic industry means possessing anti-inflammatory and wound-healing properties, as well as favorably acting on the mucous membrane of the prosthetic bed.

The study aims s are researching the negative effect of nicotine-containing vapes on physical and chemical parameters of oral fluid and morphotyping of dried oral fluid drop among young somatically healthy individuals. Material and methods. The study included 20 people between the ages of 18 and 24 years old, divided into 2 groups: the «Vape» group (n=12) human only nicotine-containing vape for at least 2 years and the «Control» group (n=8) not human nicotine in any form. pH, thiocyanate (rhodonide) concentrations, surface tension, oral fluid volume, hygiene indices and periodontal indices were studied. The morphotype of dried oral fluid drop was analyzed. Results. In the «Control» group in 3 cases gingivitis chronic K05.1 was diagnosed, and in the patients of the «Vape» group in 9 cases. It was found that the rhodonide content in the «Vape» group before «vaping» was higher than in the «Control» group and was Me= 1.31 mM/L and Me=0.58 mM/L respectively p=0.012. After vape application, the concentration of rhodonides in oral fluid increased in 1.16 times (p=0.0077), nitrite ions content from Me=0.09 mg/L to Me=0.32 mg/L (p=0.07), pH increased to Me=7.64; (LQ=7.45; HQ=7.67) (p=0.07) (p=0.07). The volume of RW in the Vape group remains 2.8 times smaller than in the Control group (p=0.012). The microcrystallization pattern of the oral fluid drop in the «Vape» group before «steaming» more often corresponded to type II A, and after «steaming» in 33.4% cases type III was determined, in 25% – type II B. Conclusions. Thus, in «vapers» of 18–24 years old statistically reliable reduction of oral fluid volume, high values of hygiene index shift of acid-base balance in the direction of alkalosis creates conditions in the oral cavity for the development of periodontal diseases and the emergence of cariesogenic situation. There was an increase in the concentration of rhodanide and nitrite ions, which in combination with other components of vape aerosols can be considered as procarcinogens, syncarcinogens and cocarcinogens. The change in the morphology of facies pattern, type of microcrystallization of oral fluid drop in the dynamics of vape use corresponds to the vector of changes observed in other inflammatory diseases of the oral cavity

equipment (braces) on the biochemical parameters of oral fluid. Materials and methods. The study involved patients aged 18 to 22 years who are undergoing orthodontic treatment with a bracket system. Thegroup of examined persons was 25 people. The control group included 15 practically healthy people without braces. All patients underwent dental status assessment (Green – Vermillion hygiene index – simplified IG-Y; PMA inflammation index), laboratory examination of oral fluid before and after controlled oral hygiene. The biochemical analysis included determination of the acid-base balance in the oral fluid using a pH meter, assessment of free radical oxidation by chemiluminogram parameters by biochemiluminescence and by levels of molecular products of lipid peroxidation (diene and triene conjugates, Schiff bases), activity of the enzyme alkaline phosphatase, concentrations of total protein and lactate. Results and discussions. In patients undergoing orthodontic treatment with a bracket system, an insufficient level of oral hygiene and inflammatory manifestations in the gums of moderate severity were revealed. The level of the acid-base balance of the oral fluid before controlled hygiene was equal to 6.8±0.19, that is, below the range of normal pH values in the oral cavity. After hygiene, the pH of the oral fluid returned to the norm of 7.1±0.2. In patients with braces, activation of free radical oxidation and an increase in lipoperoxidation parameters – triene conjugates and Schiff bases, increased activity of alkaline phosphatase, total protein and lactate levels took place.Cоnclusion. After hygienic treatment of the oral cavity, the biochemical parameters did not differ statistically significantly from the control data.
