BACKGROUND
This study aimed to investigate the impact of the blood flow restriction bladder type (single- [SC-BFR] vs. multi-chambered [MC-BFR]) on cardiovascular responses with exercise sessions incorporating multiple sets to volitional failure in a randomized, crossover experimental design.

METHODS
Twenty-seven healthy, physically active participants (11 females; age: 22.6±5.7; BMI: 25.0±4.1 kg/m2; ~93% reported regular resistance training within 6 months) randomly performed wall squats to failure (4 x sets to failure, 20% 1RM, 60% limb occlusion pressure, 1 min rest between sets) in each of three conditions: SC-BFR (using the Delfi Personalized Tourniquet Device), MC-BFR (using the BStrong Cuffs), and N-BFR (no BFR control). Hemodynamic assessments and indices of arterial stiffness were monitored immediately before and after each exercise session.

RESULTS
SC-BFR blunted post-exercise increases in carotid-femoral pulse wave velocity (p = 0.328) whereas the other conditions showed elevations (p &lt; 0.05).

CONCLUSION
The bladder design of a BFR cuff impacts the acute responses to exercise, as SC-BFR mitigates post-exercise arterial stiffness responses compared to MC-BFR and N-BFR. This was the first intervention to examine the acute effects of BFR bladder design on arterial stiffness during lower body exercise. SC-BFR appears to be a safe option for lower limb occlusion training.

Objectives. The article presents a study of heart rate variability using multivariate discriminant analysis. Representing an effective statistical method of classification, discriminant analysis can be used to divide objects into groups based on differences in the parameters characterizing these objects. The effectiveness of multivariate discriminant analysis, which is actively used in medicine to diagnose cardiovascular pathologies, is due to the wide range of analyzed parameters: statistical, spectral, and autocorrelation. The aim of the work is to identify the parameters of variational pulsometry, which provide the best distinction between healthy patients and patients with arrhythmia, by means of discriminant analysis.Methods. The durations of cardiac intervals of patients aged 63–72 years, which had been placed in the open database of biomedical signals PhysioNet.org, were used as initial data. When selecting the arguments of the discriminant function, priority was given to parameters that were weakly correlated with each other, had a normal distribution, and differed between healthy and ill patients. The statistical significance of differences between the parameters of the two groups was tested using Student’s t-test and Mann–Whitney U test.Results. Two discriminant functions were obtained: the first depended on three time-domain parameters, while the second included one spectral and one autocorrelation parameter in addition to time-domain parameters. In both cases, the average values of the discriminant function for healthy and sick patients were calculated. The statistical significance of differences in the average values of the discriminant function in the two groups was investigated using Student’s t-test.Conclusions. The values of the first discriminant function are shown to differ insignificantly between healthy and sick patients, while the inclusion of autocorrelation and spectral parameters in the number of arguments of the discriminant function provides pronounced and statistically significant differences between patients of the two groups. Thus, the high significance of spectral and autocorrelation parameters in arrhythmia diagnosis was demonstrated.

Published: February 2025

Nigeria is still unable to meet even the most basic of its energy needs, this lack of power is most evident in houses located in the North-Central and North-East areas. This paper focused on evaluating geothermal potential through remote sensing techniques in parts of Northern Nigeria. Four digital elevation model (DEM) scenes, three Landsat-9(OLI-2/TIR-2) with minimum zero or minimum cloud cover (<6%), and Terra Moderate Resolution Imaging Spectroradiometer satellite images for the research region were processed using ArcMap 10.7.1, Google Earth Pro, and QGIS 3.36.3. The linear correlation analysis performed between Landsat LST and MODIS LST images showed a high correlation coefficient (R² = 0.907). Anomalously high lineament density correlates with high land surface temperature, dominantly in the basement complex of the study area; it's possible that the fracturing will increase the permeability, enabling warm or hot springs to rise to the surface. Fault lines that permit the movement of hot/warm water to the Earth's surface can be linked to active geothermal zones. The stream/rivers in or around the targeted high LST are probably thermal springs, as they were overlaid on the LST, and high-temperature spots(>280) were identified. The regions around Jibam, Langtang, Aikri, Adikpo, Shemdam, and Ashinge prove to be areas where warm or hot springs can be located.

IntroductionFollowing the Coronavirus Disease 2019 (COVID-19) pandemic, most universities around the world transitioned from in-person classrooms to online learning methods. This study aimed to explore the initial experiences of medical students with e-learning during the pandemic at Shiraz University of Medical Sciences in Iran, as well as to identify differences in students’ general perceptions based on their demographic characteristics.MethodsThis cross-sectional study was conducted on 507 medical students during the COVID-19 pandemic. To gather information for this study, a questionnaire created by the researchers was used, which consisted of six variables and 26 items on a Likert scale. The content validity of the questionnaire was assessed using Content Validity Index (CVI) and Content Validity Ratio (CVR). The reliability of the questionnaire, based on the internal consistency of the questions, was confirmed by a Cronbach’s alpha of 97.5%. Data were analyzed using a one-sample t-test, independent t-test, ANOVA, and MANOVA.ResultsStudents had satisfactory e-learning experiences, and the average of e-learning components was: technological facilities (4.29 ± 1.13), technical support (4.00 ± 1.08), e-content quality (3.84 ± 1.05), synchronous education (3.59 ± 1.31), asynchronous education (3.73 ± 1.20), and teacher-student interaction (3.63 ± 1.32). Students’ perceptions of the e-learning environment were shown to be substantially connected to their age, access to electronic devices, computer proficiency, prior experience regarding e-learning, and the school in which they are studying, respectively (P = 0.027). Furthermore, students who had access to a computer were more satisfied than those who only had access to a mobile phone (P &lt; 0.001). In medical schools where teacher-student interaction was better, more satisfaction was observed (P &lt; 0.001). The gender factor had no effect on students’ views.ConclusionEven though it seems like e-learning can be a good substitute for or complement to face-to-face training, the most important thing that makes this method more effective is the interaction between the teacher and the students.

ObjectivesEntrepreneurship in Pakistan is steadily growing, significantly impacting on economic development and job creation, despite facing several challenges. This study aimed to investigate the perceptions of students and faculty members about entrepreneurship in public and private universities in Pakistan. It also sought to evaluate the barriers and motivational factors promoting entrepreneurship among these universities.MethodsA cross-sectional study was conducted, and a comprehensive questionnaire was utilized to collect data. A total of 213 individuals from different disciplines took part in the study. This study examines the similarities and differences in the views of faculty members and students toward entrepreneurship by using SPSS 25.ResultsIn terms of motivation, 72% of private sector participants cited income satisfaction as a key factor, compared to 58% in the public sector. The proportion of participants willing to apply for funding for entrepreneurial support was 68%, predominantly among private sector participants (75% vs. 61%). Access to training programs was reported by 62%, but private universities provided 35% more institutional support. The results of the chi-squared test revealed that institutional business courses, startup funding, and funding applications were significantly correlated in public and private sectors. Key risks identified included a lack of access to funding (42%), inadequate workforce skills (37%), and limited market opportunities (29%). Fresh graduate entrepreneurial failures were attributed to lack of experience (43%) and market adaptability (33%). The study also highlighted the connection between entrepreneurial activities and mental health issues, including frustration, burnout, and a lack of motivation for business. Both groups showed similar perceptions regarding business potential and suggested mentorship as a key area for improving entrepreneurship.ConclusionThe study suggests that promoting entrepreneurship in Pakistan should focus on targeted interventions through the initiation of psychoeducational training, networking opportunities, and mentorship. Additionally, these policies should identify the sectoral issues they aim to solve while incorporating mental health policies to create a robust entrepreneurial ecosystem. Extending the study to include various industries and stakeholders will be another direction for future research to improve policy and practice.

BackgroundTo improve the scientificity of the evaluation results of the planting performance of the Yellow River sediment based on planting substrate.MethodsThis study replaced the natural soil with Yellow River sediment, used cement as the cementing material, added different proportions of organic matter and amendment of habitat material to prepare planting substrate based on the Yellow River sediment, and carried out experiments by using oats and proposed a combined SQI-CRITIC combined weighting calculation method based on the least square method for its evaluation.ResultsThe results showed that (1) different proportions of cement and amendment of habitat material led to significant variations in the planting performance of the planting substrate based on Yellow River sediment: among the 5# mix ratio, the plant height (12.5 cm) and biomass (3.06 g) of oats reached extreme values. Photosynthetic rate (1.97 μmol∙m−2∙s−1) and transpiration rate (0.25 mmol∙m−2∙s−1) were significantly higher than the other fitness ratio components (P &lt; 0.05), while the stomatal width (87.03 μm) was the largest and stomatal density (19.6%) was the lowest (P &lt; 0.05). (2) The results calculated by the SQI-CRITIC combination model based on the least square method are scientific and effective, more accurate and in line with the actual situation. (3) The comprehensive analysis recommended the use of a quality mix ratio (mixture of sediment, amendment of habitat material, organic matter, cement = 100:3:12:4) in ecological restoration to achieve the best plant growth and ecological restoration effect.ConclusionThe experimental results can be extended to more areas that need to use sandy soil for ecological restoration, with a view to providing a theoretical basis for soil quality evaluation, soil and water conservation control, and ecological construction in the Yellow River Basin.
