Microfluidic Chip for Cell Fusion and In Situ Separation of Fused Cells.

Electrofusion is an effective method for fusing two cells into a hybrid cell, and this method is widely used in immunomedicine, gene recombination, and other related fields. Although cell pairing and electrofusion techniques have been accomplished with microfluidic devices, the purification and isolation of fused cells remains limited due to expensive instruments and complex operations. In this study, through the optimization of microstructures and electrodes combined with buffer substitution, the entire cell electrofusion process, including cell capture, pairing, electrofusion, and precise separation of the targeted fused cells, is achieved on a single chip. The proposed microfluidic cell electrofusion achieves an efficiency of 80.2 ± 7.5%, and targeted cell separation could be conveniently performed through the strategic activation of individual microelectrodes via negative dielectrophoresis, which ensures accurate release of the fused cells with an efficiency of up to 91.1 ± 5.1%. Furthermore, the survival rates of the cells after electrofusion and release are as high as 94.7 ± 0.6% and 91.7 ± 1.2%, respectively. These results demonstrate that the in situ cell electrofusion and separation process did not affect the cell activity. This chip offers integrated multifunctional manipulation of cells in situ, and can be applied to multiple fields in the future, thus laying the foundation for the field of precise single-cell analysis.

While the Shuttle Run-test training group got an average of 41.792. Based on the results of the study, it can be concluded that the Harvard Step-test exercise has a more effective pulse rate increase compared to the Shuttle Run-test exercise.

Improved paired light and scanning electron microscope imaging technique for identifying nannofossils in Arctic sediments

Calcareous nannofossils provide biostratigraphic age-markers for Pleistocene Arctic Ocean sediments. However, Pleistocene Arctic sediments are dominated by fine-grained terrigenous material, and commonly contain rare and poorly preserved coccolith specimens that can be difficult to identify under the light microscope (LM). Using paired observations of the same specimens under LM and a scanning electron microscope (SEM), we recently discovered that poorly preserved Noelaerhabdaceae specimens that cannot be identified at the species level were previously classified as Gephyrocapsa huxleyi using LM observations alone. Moreover, the visual resemblance under LM between G. huxleyi and another Quaternary marker species, Pseudoemiliania lacunosa, also led to occasional misdiagnosis. Given the importance of G. huxleyi and P. lacunosa for stratigraphic age control, this has potentially profound implications for our understanding of the paleoceanographic history of the Arctic, and also other ocean basins. This study focuses on challenges met in improving and applying the paired LM-SEM technique for observation of the same nannofossil specimens, and on its subsequent adjustments in the case of Quaternary Arctic sediments, which often contain low abundances of calcareous micro- and nannofossils. Moreover, we review morphological aspects and discuss potential difficulties in unambiguously identifying G. huxleyi, P. lacunosa and Gephyrocapsa under LM and illustrate the need of integrating SEM images – which can be difficult to obtain in low-diversity assemblage sediments dominated by silt and clay.

Implementation of Think Pair and Share (TPS) Technique in Listening to Short Story Texts Learning

This research aims to determine whether there are differences in students' abilities in listening to short story texts using the Think-Pair-Share (TTPS) cooperative learning method. Conducted as a quasi-experimental study, the sample comprised 11th-grade students from SMA DDI Maros. Data collection involved text analysis techniques, and the obtained data were analyzed through stages including the creation of raw score lists, frequency distributions, descriptive statistical analysis, and inferential statistical analysis. The results indicate significant differences in learning outcomes between students using the TTPS method and those not using it. The use of TTPS improved students' listening comprehension of short story texts, as evidenced by the mean score of 74.36 (high category) in the experimental class compared to 58.46 (low category) in the control class. This demonstrates that the TTPS method effectively enhances students' listening skills.

THE EFFECT OF SELF-ACUPRESSURE ON REDUCING BLOOD PRESSURE, HEADACHE AND SLEEP QUALITY DISORDERS IN HYPERTENSIVE PATIENTS

Hypertension is still a major health problem in Indonesia. Various efforts to overcome the problem of hypertension have been made, both pharmacological and non-pharmacological treatments. A therapy based on the patient's habits or culture will certainly be easier to implement and obey by. Therefore, this study aims to analyze the effect of self-acupressure on blood pressure, headache, and sleep quality of hypertensive patients. The research method used is a quasi-experiment, single-group pre-post-test design. The sample in this study were hypertensive patients who fit the inclusion and exclusion criteria at Wonokerto Health Centre, Pekalongan Regency. The data analysis used was univariate and bivariate analysis. Bivariate analysis used paired group t-test technique. The results showed that there was an effect of self-acupressure in reducing systolic blood pressure (p-value: 0.004), headache pain scale (p-value: 0.001), and decreased sleep quality disorder score (p value: 0.000). Massaging at acupressure points has the effect of improving blood flow, stimulating endorphin hormones and providing a relaxing effect so that it can reduce blood pressure, headache pain scale and sleep quality disturbance scores. Recommendations for future research are to add a control group and/or compare it with other independent complementary therapy techniques.

Optimization of resource allocation in 5G networks: A network slicing approach with hybrid NOMA for enhanced uRLLC and eMBB coexistence

SummaryTraditional Orthogonal Multiple Access (OMA) and spectrum sharing methods struggle to provide the diverse quality of service (QoS) demands for enhanced mobile broadband (eMBB), ultra‐reliable low latency communications (uRLLC), and massive machine type communications (mMTC) leading to suboptimal performance and service quality degradation. Single‐carrier‐non‐orthogonal multiple access (SC‐NOMA) appears to be a more optimized solution. It can serve multiple users simultaneously on the same time‐frequency resources. This approach offers both enhanced spectrum efficiency and meets the QoS requirements for the coexistence of eMBB, uRLLC, and mMTC. However, SC‐NOMA has some drawbacks. Decoding a user's signal involves a complex successive interference cancellation (SIC) process that gets harder with more users causing delays and errors. Additionally, strong user signals can interfere with weaker ones, limiting the number of users per channel. In order to overcome the drawbacks associated with OMA and SC‐NOMA, this paper introduces a new method called user‐paired NOMA (hybrid NOMA). Hybrid NOMA adopts a strategic approach, employing two user pairing techniques: near‐far/far‐near (NF‐FN) and near‐near/far‐far (NN‐FF). NF‐FN pairing prioritizes users with similar signal strengths but different distances from the base station. This minimizes interference for the weaker user during SIC. NN‐FF pairing, on the other hand, groups users with similar signal strengths and proximity. This approach further simplifies SIC and minimizes potential interference altogether. The simulation results demonstrate trade‐offs between eMBB and uRLLC performance. OMA suffers with dedicated resource allocation, while SC‐NOMA balances performance but experiences interference. NN‐FF prioritizes eMBB and offers best latency, while NF‐FN prioritizes uRLLC with high spectral efficiency but suffers from higher latency. Finally, by providing a thorough grasp of how hybrid NOMA resource allocation works to improve the performance of various use cases, this research makes a significant contribution to the field of 5G spectrum optimization.

Using continuous relative phase and modified vector coding analyses to quantify spinal coordination and coordinative variability for healthy and chronic low back pain patients: An exploratory comparative analysis

Differences in coordination and coordinative variability are common in people with low back pain. While differences may relate to the different analyses used to quantify these metrics, the preferred approach remains unclear. We aimed to compare coordination and coordinative variability, in people with and without low back pain performing a lifting/lowering task, using continuous relative phase and vector coding procedures, and to identify which technique better detects group differences. Upper lumbar (T12-L3), lower lumbar (L3-S1), and hip angular kinematics were measured using electromagnetic motion capture during 10 crate lifting/lowering repetitions from adults with (n = 47) and without (n = 17) low back pain. Coordination and coordinative variability for the Hip-Lower Lumbar and Lower Lumbar-Upper Lumbar joint pairs were quantified using mean absolute relative phase and deviation phase (continuous relative phase), and coupling angle and coupling angle variability (vector coding), respectively. T-tests examined group differences in coordination and variability. Cohen’s d bootstrapping analyses identified the more sensitive technique for detecting group differences. Less in-phase and more variable behavior was observed in the low back pain group, mostly independent of joint pair and analytical technique (P < 0.05, Cohen’s d range = 0.61 to 1.33). Qualitatively, the low back group limited motion at the lower lumbar spine during lifting/lowering. Continuous relative phase was more sensitive in detecting group differences in coordinative variability, while vector coding was more sensitive towards differences in coordination. These procedures convey distinct information and have their respective merits. Researchers should consider the choice of analytical techniques based on their study objectives.

Shifting from Immunohistochemistry to Screen for ALK Rearrangements: Real-World Experience in a Large Single-Center Cohort of Patients with Non-Small-Cell Lung Cancer.

The identification of ALK fusions in advanced non-small-cell lung carcinoma (aNSCLC) is mandatory for targeted therapy. The current diagnostic approach employs an algorithm using ALK immunohistochemistry (IHC) screening, followed by confirmation through ALK FISH and/or next-generation sequencing (NGS). Challenges arise due to the infrequency of ALK fusions (3-7% of aNSCLC), the suboptimal specificity of ALK IHC and ALK FISH, and the growing molecular demands placed on small tissue samples, leading to interpretative, tissue availability, and time-related issues. This study investigates the effectiveness of RNA NGS as a reflex test for identifying ALK fusions in NSCLC, with the goal of replacing ALK IHC in the systematic screening process. The evaluation included 1246 NSCLC cases using paired techniques: ALK IHC, ALK FISH, and ALK NGS. ALK IHC identified 51 positive cases (4%), while RNA NGS detected ALK alterations in 59 cases (4.8%). Of the 59 ALK-positive cases identified via NGS, 53 (89.8%) were confirmed to be positive. This included 51 cases detected via both FISH and IHC, and 2 cases detected only via FISH, as they were completely negative according to IHC. The combined reporting time for ALK IHC and ALK FISH averaged 13 days, whereas ALK IHC and RNA NGS reports were obtained in an average of 4 days. These results emphasize the advantage of replacing systematic ALK IHC screening with RNA NGS reflex testing for a more comprehensive and accurate assessment of ALK status.

Persistent inward currents in tibialis anterior motoneurons can be reliably estimated within the same session

The response of spinal motoneurons to synaptic input greatly depends on the activation of persistent inward currents (PICs), the contribution of which can be estimated through the paired motor unit technique. Yet, the intra-session test–retest reliability of this measurement remains to be fully established. Twenty males performed isometric triangular dorsiflexion contractions to 20 and 50 % of maximal torque at baseline and after a 15-min resting period. High-density electromyographic signals (HD-EMG) of the tibialis anterior were recorded with a 64-electrode matrix. HD-EMG signals were decomposed, and motor units tracked across time points to estimate the contribution of PICs to motoneuron firing through quantification of motor unit recruitment-derecruitment hysteresis (ΔF). A good intraclass correlation coefficient (ICC = 0.75 [0.63, 0.83]) and a large repeated measures correlation coefficient (rrm = 0.65 [0.49, 0.77]; p < 0.001) were found between ΔF values obtained at both time points for 20 % MVC ramps. For 50 % MVC ramps, a good ICC (0.77 [0.65, 0.85]) and a very large repeated measures correlation coefficient (rrm = 0.73 [0.63, 0.80]; p < 0.001) were observed. Our data suggest that ΔF scores can be reliably investigated in tibialis anterior motor units during both low- and moderate-intensity contractions within a single experimental session.

Plasma immune signatures can predict rejection-free survival in the first year after pediatric liver transplantation

After pediatric liver transplantation (pLT), children undergo life-long immunosuppression since reliable biomarkers for the assessment of rejection probability are scarce. In the multicenter (n= 7) prospective clinical cohort "ChilSFree" study, we aimed to characterize longitudinal dynamics of soluble and cellular immune mediators during the first year after pLT and identify early biomarkers associated with outcome. Using a Luminex-based multiplex technique paired with flow cytometry, we characterized longitudinal dynamics of soluble immune mediators (SIMs, n= 50) and immune cells in the blood of 244 patients at eight visits over 1 year: before, and 7/14/21/28 days and 3/6/12 months after pLT. The unsupervised clustering of patients based on SIM profiles revealed six unique SIM signatures associated with clinical outcome. From three signatures linked to improved outcome, one was associated with 1-year-long rejection-free survival and stable graft function and was characterized by low levels of pro-inflammatory SIMs (CXCL8/9/10/12, CCL7, SCGF-β, sICAM-1), and high levels of regenerative (SCF, TNF-β) and pro-apoptotic (TRAIL) SIMs (all, p <0.001, fold change >100). Of note, this SIM signature appeared 2 weeks after pLT and remained stable over the entire year, pointing towards its potential as a novel early biomarker for minimizing or weaning immunosuppression. In the blood of these patients, a higher frequency of CD56bright natural killer cells (p <0.01), a known hallmark also associated with operationally tolerant pLT patients, was detected. The concordance of the model for prediction of rejection based on identified SIM signatures was 0.715, and 0.795, in combination with living-related transplantation as a covariate, respectively. SIM blood signatures may enable the non-invasive and early assessment of rejection risks in the first year after pLT, paving the way for improved clinical management. ChilSFree represents the largest pediatric liver transplant (pLT) cohort with paired longitudinal data on soluble immune mediators (SIMs) and immune phenotyping in the first year after pLT. SIM signatures allow for the selection of rejection-free patients 2 weeks after pLT independently of patient diagnosis, sex, or age. The SIM signatures may enable the non-invasive and early assessment of rejection risks, paving the way for minimization or withdrawal of immunosuppression after pLT.

The effect of animal name and wall shoot training on the accuracy of shooting free throw in terms of hand eye coordination in beginner athletes

Providing training program treatment to athletes is the most important thing in the success of a coach to get more optimal results, one of which is using modified exercise animals name and wall shoots. This study aims to analyze: 1) the difference in the effect of animals name and wall shoot training on the accuracy of free throw shooting techniques, 2) the difference in the influence between athletes who have high and low hand eye coordination on the accuracy of shooting free throw, 3) the interaction between animals name and wall shoot training and high and low hand eye coordination on the accuracy of shooting free throw in beginner class athletes. This study is a type of factorial 2x2 experimental research with a population of 38 athletes and then the basis for determining samples using purposive sampling techniques based on inclusion criteria set by researchers, so that the sample in this study amounted to 20 athletes who would later be divided into each group using ordinal pairing techniques. The instrument used is to measure the accuracy of shooting free throw, namely drill shoot free throw, while hand eye coordination uses a one-pint image. The data analysis technique used is ANOVA two way. The results of this study show that: 1) there is a significant difference in the effect between animal name and wall shoot exercises on the accuracy of shooting free throw, as evidenced by the results of Fhitung's analysis of 6.741 with sig values. amounted to 0.001. 2) there is a significant difference in the influence on the ability of the hand eye coordination system on the free throw shooting accuracy component, as evidenced by the result of a Fcalculate value of 32.463 with a sig value. amounted to 0.000. 3) there is a significant interaction between the name of the animal and the wall shooting exercise in terms of free throw accuracy, as evidenced by the results of the Fcalculate value of 2.294 with the sig value. 0,003. So it can be concluded that the two exercises significantly affect the accuracy of the free throw shooting itself. These factors need to be considered in planning and implementing training programs to improve athlete performance, especially in terms of optimizing the accuracy of free throw shooting techniques in basketball athletes in the beginner class. Keywords: Animals Name, Wall Shoot, Precision, Shooting Free Throw, Hand Eye Coordination, Athletes.

Resource allocation of cognitive relay networks under continuous transmission mechanism

This paper considers the joint power allocation, path selection and subcarrier pairing design of cognitive radio cooperative networks, where the transmission power of secondary users is limited by its own power budget and the tolerable interference threshold of primary users. In particular, a continuous transmission mechanism rather than intermittent emission, leading to severe signal interference between primary and secondary users, as well as mutual interference between secondary users, is taken into account. This cooperative cognitive radio network is seen as an improvement in the sense that the source transmitter can continuously transmit symbols without silence. Although traditional cooperative network technology has long been applied to the cognitive radio field and it has been proposed to allow continuous transmission signals by source transmitter, the deployment of such improved cooperative behavior in cognitive radio networks has not been reported yet. This improvement assumption may render serious mutual interference between the relay station and the destination receiver, and the signal interference borne by the primary user will also exceed the threshold value, if there is no elaborate signal design and resource scheduling. In order to make full use of the available resources, this paper presents the closed-form solution of the power allocation, the decision criteria of the path selection and the subcarrier pairing technique for the problem of maximization of the sum rate of secondary users in such networks under the dual constraints of the power budget and the interference threshold. Simulation results show that the continuous transmission behavior at the source significantly outperforms the traditional switching back and forth between on and off.

The Effectiveness of "Kancani": An REBT-Based Web Application on Junior High Students' Subjective Well-Being

Abstract. The high prevalence of mental health issues among Indonesian adolescent students signifies persistently low levels of subjective well-being. Junior high school students tend to engage in negative thinking and experience a decline in positive feelings, contributing to mental health issues, as well as low life satisfaction. To address this, enhancing socio-emotional abilities such as emotion regulation, especially in dealing with irrational thoughts as the root of the problem, becomes crucial. This research aims to evaluate the effectiveness of the "Kancani" web app, which implements Rational-Emotive Behavior Therapy (REBT)-based interventions on the subjective well-being of junior high school adolescents. A quasi-experimental one-group pretest-posttest design was employed with 22 junior high school participants aged 12-15 who received the intervention for 2 weeks. The research instruments used were a 25-item Subjective Well-Being scale measuring positive affect (a = 0.861), negative affect (a = 0.861), and life satisfaction (a = 0.828). Data were tested using the paired samples t-test technique. Data were analyzed using paired samples t-test showed that the Kancani web app, with REBT-based interventions, effectively increased the subjective well-being of junior high school students, particularly in the aspects of positive affect and life satisfaction (p = 0.004 &lt; 0.05), although not significantly in reducing negative affect (p = 0.104 &gt; 0.05). Nevertheless, the improvement in the subjective well-being of students after the intervention is still reflected in the descriptive analysis of the mean differences, indicating an increase in positive affect and life satisfaction, as well as a decrease in negative affect.
