This article documents a preliminary appraisal of Turkiye's relations with the newly formed Alliance of the Sahel States (AES), within the confines of security engagements, economic entanglements, and humanitarian/cultural interactions. To achieve this, the study investigates how the Heartland Theory and the smart power paradigm could assist in exploring Turkiye's relations with the Alliance. Analyzing official documents and secondary data, the paper takes the view that defense and security engagements have taken center stage of the relations, relegating economic and humanitarian issues to the periphery. This shift positions Turkiye to play a very influential role in Sahelian affairs, particularly in their defense and security. Considering the stiff competition from key non-Western countries with vested interest in the region, especially China and Russia, Turkiye must carefully navigate its relations with regional bodies like the Economic Community of West African States (ECOWAS) and these other external actors to promote regional stability and cooperation. Amidst the growing discontent expressed by the Alliance towards the Western countries, Ankara is compelled to exert its influential role in a manner different from its predecessors. Keywords: Turkiye, Alliance of Sahel States, Economy, Humanitarian Engagement, Security, West Africa, Introduction The Alliance of Sahel States (AES), comprising Mali, Burkina Faso, and Niger, is a coalition of neighboring Sahelian nations that have recently experienced coup d'etats and have decided to [...]

Many studies have identified differences in the effectiveness of the integration of blended learning and project-based learning (BPjBL) models on student achievement. However, the results of previous studies showed different results. Therefore, this study aims to determine the differences in the effectiveness of the integration of blended learning and project-based learning (BPjBL) models on student achievement, compared to traditional learning. The design used in this study was a contrast group meta-analysis. The studies analyzed to calculate the effect size were 11 primary studies that met the established inclusion criteria. To be more accurate, data analysis was performed with the help of JASP software version 0.16.3. The results of the analysis using the random effects approach obtained an overall effect size (d = 1.28; p <0.05). This effect size is included in the large effect category. It can be concluded that the use of the BPjBL model has a major effect on student achievement when compared to traditional learning. The meta-analysis in this study has no problem with publication bias, so this meta-analytic research is objective and scientifically justifiable. The results of this meta-analysis research show more accurate information, which can be used as a basis for policymaking, so as to improve the quality of learning.

Abstract Background Defining the protective thresholds against the severe-acute-respiratory-syndrome-related corona virus-2 pandemic is a crucial challenge. To reduce the risks of severe disease, hospitalization, and death, various COVID-19 vaccines have been rapidly developed. Aim of the work This study aimed to assess the impact of three common COVID-19 vaccine types; two mRNA COVID-19 vaccines: (Pfizer/BioNTech’s BNT162b2 and Moderna’s mRNA-1273), one adenoviral vector vaccine: Oxford/AstraZeneca’s ChAdOx1, and one inactivated vaccine (Sinovac Biotech/China’s Sinovac) on the level of neutralizing antibodies, considering factors such as vaccine type, demographic characteristics, and hybrid immunity. We conducted a direct comparative analysis involving 300 healthcare workers, both with and without prior SARS-CoV-2 infection (B.1, C.36.3, and AY.32 (Delta) variants). Neutralizing antibodies levels were measured at baseline (before vaccination), before the second dose, and six months after the second dose. Results The results showed a significant increase in neutralizing antibodies levels after complete vaccination with all vaccine types. Among healthcare workers, those vaccinated with mRNA vaccines (Moderna or Pfizer) exhibited the highest neutralizing antibodies titers, followed by AstraZeneca, and finally Sinovac with the lowest titer. On studying the effect of previous COVID-19 infection after vaccination, no significant difference in neutralizing antibodies levels was observed between healthcare workers vaccinated with mRNA or AstraZeneca vaccines, both with prior COVID-19 infection, following the first and six months after the second dose. Conclusion These findings suggest that individuals with prior COVID-19 may only require a single dose of mRNA or AstraZeneca vaccines to achieve a similar level of immunization as those without prior COVID-19 who completed the vaccination program. Highlights There is a significant increase in neutralizing antibodies levels after complete vaccination against COVID-19 Vaccination with mRNA vaccines exhibits the highest neutralizing antibodies titers. Vaccination with Sinovac exhibits the lowest neutralizing antibodies titers. Graphical abstract

Abstract Background Differentiation between isolated hypogonadotropic hypogonadism (IHH) and constitutional delay in puberty (CDP) throughout adolescence can be challenging for doctors. This study examines the withdrawal effects of short-term, low-dose testosterone treatment (testosterone priming) on the ability of dynamic testing to distinguish between CDP and IHH based on activation of the hypothalamo-pituitary–testicular axis. Methods A case–control study included 20 boys with delayed puberty (group A) and 20 patients with IHH (group B). Both groups underwent Triptorelin and human chorionic gonadotropin (hCG) stimulation tests before and 2 months after testosterone injections (100 mg) intramuscularly every 4 weekly for 3 months. Results The triptorelin-stimulated 4-h LH with a cutoff of 2.4 IU/L and the hCG-stimulated testosterone with a cutoff of 1.160 ng/mL had sensitivities of 65% each, and specificities of 90% and 95%, respectively, to diagnose CDP. After testosterone withdrawal, the cut-off values for 4-h LH were 8.850 IU/L and 3.190 ng/mL for hCG-stimulated testosterone. Basal inhibin B > 88.25 pg/ml was found to be a differentiating factor in diagnosing CDP after testosterone withdrawal. Conclusions following the withdrawal of testosterone therapy, Inhibin B levels or 4-h stimulated LH are the most effective discriminant assays to distinguish CDP from IHH.

RM can further complicate the clinical course by causing acute kidney injury (AKI). We present a case of Community-acquired pneumonia with AKI complicated by rhabdomyolysis in a resource-limited setting.Case Presentation: A 67-year-old male presented with high fever, cough, and shortness of breath. He had no significant medical history. On examination, he was febrile, tachypneic, and tachycardic, with right-sided lung crackles. Lab tests showed elevated inflammatory markers and impaired kidney function. Chest radiography revealed right upper lobe consolidation, confirming pneumonia and AKI. He was treated with fluids, antibiotics, and supportive care, but his condition worsened, requiring intensive care unit (ICU). In the ICU, dark urine and elevated creatine kinase confirmed rhabdomyolysis. After aggressive fluid therapy and antibiotics the patient improved over six days and was transferred to the ward. By day 10, he fully recovered and was discharged with follow-up.Conclusion: This case underscores the importance of early recognition and prompt management of CAP complicated by AKI and rhabdomyolysis, even in resource-limited settings. Timely intervention can lead to favorable outcomes despite challenges.Keywords: community-acquired pneumonia, acute kidney injury, rhabdomyolysis, resource limit setting

Tubulocystic renal cell carcinoma (RCC) is a rare renal cancer first recognized by the WHO in 2016 as independent disease category, characterized by its typically indolent features and low rates of metastasis. We present a 35-year-old male with tubulocystic RCC diagnosed incidentally on evaluation of flank pain. Magnetic resonance imaging showed Bosniak class 4 renal cyst, although initial computed topography showed a hypodense nonenhancing lesion classified as Bosniak 1 cyst. Patient underwent robotic assisted partial nephrectomy, histopathology confirmed as tubulocystic RCC. This case highlights the importance of considering tubulocystic RCC in the differential diagnoses of renal cysts and other solid renal masses to ensure timely and effective treatment plan.

Results: Compared with the infected non-treated group, all infected treated groups showed significant reductions in brain cyst numbers (all P

Abstract The growth of material science and technology places high importance on creating better processes for synthesizing copper nanoparticles. Thus, an easy, ecological, and benign process for producing copper nanoparticles (CuNPs) has been developed using Priestia sp. bacteria utilizing a variety of low-cost agro-industrial wastes and byproducts. The biosynthesis of CuNPs was conducted using glucose medium and copper ions salt solution, then it was replaced by utilizing low-cost agro-industrial wastes. UV–visible spectroscopy, dynamic light scattering (DLS), X-ray diffraction (XRD), High-resolution transmission electron microscope (HR-TEM), Attenuated Total Reflectance and Fourier transform infrared (ATR-FTIR), and zeta potential were used to characterize the biosynthesized CuNPs. The cytotoxicity of CuNPs using Vero -CCL-81 cell lines, and antibacterial and antitumor properties using human colon epithelial colorectal adenocarcinoma Caco-2-HTB-37 cell lines were assessed. The UV–visible and DLS studies revealed CuNPs formation, with a maximum concentration of 6.19 ppm after 48 h, as indicated by a 0.58 Surface plasmon resonance (SPR) within 450 nm and 57.73 nm particle size. The 16S rRNA gene analysis revealed that Priestia sp. isolate is closely related to Priestia megaterium and has been deposited in the NCBI GenBank with accession number AMD 2024. The biosynthesis with various agro-industrial wastes indicated blackstrap sugar cane molasses being the most effective for reducing CuNPs size to 3.12 nm owing to various reducing and stabilizing active compounds. The CuNPs were free of contaminants, with a sphere-shaped structure and a cytotoxicity assessment with an IC50 of 367.27 μg/mL. The antibacterial activity exhibited by the most susceptible bacteria were Bacillus cereus ATCC 11788 and Staphylococcus aureus ATCC 6538 with inhibition zones of 26.0 mm and 28.0 mm, respectively. The antitumor effect showed an IC50 dose of 175.36 μg/mL. Based on the findings, the current work sought to lower product costs and provide a practical solution to the environmental contamination issues brought on by the buildup of agricultural wastes. In addition, the obtained CuNPs could be applied in many fields such as pharmaceuticals, water purification, and agricultural applications as future aspects.

Abstract Amyotrophic lateral sclerosis (ALS) patients lack effective treatments to maintain motor and neuromuscular function. This study aimed to evaluate the effect of a home-based exercise program on muscle strength, ALS scores, and transcriptome in ALS patients, Clinical Trials.gov #NCT03201991 (28/06/2017). An open-label, non-randomized pilot clinical trial was conducted in seven individuals with early-stage ALS. Participants were given 3 months of home-based resistance exercise focusing on the quadriceps muscles. The strength of exercised muscle was evaluated using bilateral quadriceps strength with manual muscle testing, handheld dynamometers, five times sit-to-stand, and Timed-Up-and-Go before and after the exercise program. In addition, changes in the Sickness Impact Profile ALS-19 (SIP/ALS-19) as the functional outcome measure and the transcriptome of exercised muscles were compared before and after the exercise. The primary outcome of muscle strength did not change significantly by the exercise program. The exercise program maintained the SIP/ALS-19 and the ALS Functional Rating Scale-Revised (ALSFRS-R). Transcriptome analysis revealed that exercise reverted the expression level of genes decreased in ALS, including parvalbumin. Three months of moderately intense strength and conditioning exercise maintained muscle strength of the exercised muscle and ALSFRS-R scores and had a positive effect on patients’ muscle transcriptome.

Abstract This study aimed to explore the effect of enterprise resource planning (ERP), innovation (IN), and strategic planning (SP) on the organizational performance (OP) of large industrial companies in Saudi Arabia, with the mediating role of strategic decision-making (SDM). To this end, data was collected from 358 participants and analyzed using structured equation modeling (SEM) via SmartPLS 4. The findings confirmed that ERP positively affects both SDM and OP. Likewise, IN positively affects SDM but does not directly affect OP. On the contrary, SP positively affects both SDM and OP. These results emphasized the important role of SDM as a mediator. Theoretical implications highlight the integration of ERP, IN, SDM, and SP into a coherent model that explains OP dynamics. In practical terms, organizations can leverage these insights to enhance SDM processes aimed at improving operational processes. Overall, this study contributes to the literature by providing a nuanced understanding of how ERP, IN, SDM, and practices collectively drive operational processes in industrial contexts, particularly in Saudi Arabia.

Abstract Purpose The objective of this research is to explore the applicability of machine learning and fully homomorphic encryption (FHE) in the private pathological assessment, with a focus on the inference phase of support vector machines (SVM) for the classification of confidential medical data. Methods A framework is introduced that utilizes the Cheon-Kim-Kim-Song (CKKS) FHE scheme, facilitating the execution of SVM inference on encrypted datasets. This framework ensures the privacy of patient data and negates the necessity of decryption during the analytical process. Additionally, an efficient feature extraction technique is presented for the transformation of medical imagery into vectorial representations. Results The system’s evaluation across various datasets substantiates its practicality and efficacy. The proposed method delivers classification accuracy and performance on par with traditional, non-encrypted SVM inference, while upholding a 128-bit security level against established cryptographic attacks targeting the CKKS scheme. The secure inference process is executed within a temporal span of mere seconds. Conclusion The findings of this study underscore the viability of FHE in enhancing the security and efficiency of bioinformatics analyses, potentially benefiting fields such as cardiology, oncology, and medical imagery. The implications of this research are significant for the future of privacy-preserving machine learning, promoting progress in diagnostic procedures, tailored medical treatments, and clinical investigations.

Abstract Ribosomal DNA (rDNA) encodes the ribosomal RNA genes and represents an intrinsically unstable genomic region. However, the underlying mechanisms and implications for genome integrity remain elusive. Here, we use Bloom syndrome (BS), a rare genetic disease characterized by DNA repair defects and hyper-unstable rDNA, as a model to investigate the mechanisms leading to rDNA instability. We find that in Bloom helicase (BLM) proficient cells, the homologous recombination (HR) pathway in rDNA resembles that in nuclear chromatin; it is initiated by resection, replication protein A (RPA) loading and BRCA2-dependent RAD51 filament formation. However, BLM deficiency compromises RPA-loading and BRCA1/2 recruitment to rDNA, but not RAD51 accumulation. RAD51 accumulates at rDNA despite depletion of long-range resection nucleases and rDNA damage results in micronuclei when BLM is absent. In summary, our findings indicate that rDNA is permissive to RAD51 accumulation in the absence of BLM, leading to micronucleation and potentially global genomic instability.

Iron deficiency (ID) has important effects on both animals and humans, causing illness and non-specific signs. The blood changes associated with ID develop as a decrease in some erythrocyte pa-rameters and microcytic anaemia. In this study, 175 blood samples from dogs were obtained for the measurement of complete blood count (CBC), copper, and iron profiles that included serum iron, total iron binding capacity (TIBC), transferrin saturation (TS%), unbound iron binding capacity (UIBC), and canine ferritin. The cut-off values for serum iron and TS% were found using the receiver operator characteristic (ROC) curve test. The estimated cutoffs for the diagnosis of iron deficiency in the dogs were 115.74 mg/dL (serum iron) and 34.07% (TS%). The dogs with serum iron ≤ 115.74 mg/dL and TS% ≤ 34.07 were iron deficient. The dogs were divided into three groups based on the ROC curve results: iron deficiency (ID), iron deficiency anaemia (IDA), and non-iron deficiency anaemia (NIDA). The iron concentration and TS% of ID and IDA dogs were significantly lower than those of NIDA dogs, while the TIBC, UIBC, and ferritin did not differ among groups. The serum copper was not significantly lower in dogs with ID, but in the ID group (85.85±11.30 mg/dL) was less than levels in IDA and NIDA dogs (98.46±15.92 and 78.69±11.77, respectively). The study con-cluded that the ROC curve and area under the curve provided guidelines for the diagnostic accuracy of tests and the diagnosis of iron deficiency in dogs. The coefficient of variation of red blood cell distribution width (RDWc) was significantly higher when iron deficiency anaemia developed, as indicated by red blood cell (RBC) anisocytosis. The decreases in serum iron and TS% were considered "golden tests" for the diagnosis of IDA in dogs.

The Maximum Power Point Tracking (MPPT) technique in the solar energy field optimises the performance of solar panels in different atmospheric conditions and variable loads. In this study, we present a new method that uses unsupervised learning (K-means clustering) to identify the atmospheric clusters of solar irradiance and cell temperature (G, T) and delimit homogeneous atmospheric zones or clusters to reduce the search space of the optimal parameters ([Formula: see text], [Formula: see text], and [Formula: see text]). The data collected for one year is segregated into 12 clusters; in every cluster, 04 regions are defined based on every cluster’s centroid ([Formula: see text], [Formula: see text]). A local search of the reference voltage/Duty cycle per cluster region is initiated for every sensed (G, T). Variable atmospheric conditions and resistive loads are tested. The results show that the efficiency of the DC/DC converter is 97.5% with a settling time (4.013 ms/5.577 ms) compared to the Perturb and Observe (P&O) the conventional tracking method and the Particle Swarm Optimisation (PSO), both applied locally inside a cluster and a deviation of 2% from the global maximum.
