Published: August 2024

Background: Hyperuricemia is a condition in which uric acid level exceeds normal threshold. The pumpkin seed extract contains flavonoids that can lower uric acid level. This study aims to analyze the effect of pumpkin seeds (Cucurbita moschata) capsules compared to allopurinol on uric acid level in hyperuricemia patients. Methods: This was an experimental research with a non-randomized control group pretest-posttest design. A total of 63 patients (32 intervention and 31 control) with hyperuricemia enrolled in this study through purposive sampling technique. The intervention group (IG) was given pumpkin seeds and control group (CG), allopurinol. Data were analyzed using paired and independent sample t-test. Results: The result of this study showed that uric acid level significantly decreased after the pumpkin seed capsule was provided (Mean changes=-0.33 mg,dl; P<0.001). However, allopurinol played a greater role in lowering uric acid levels (Mean changes=-0.92 mg/dl; P<0.001). The mean changes of uric acid between groups was also significant (P=0.039). In addition, some of the nutrition intakes showed a significant difference after the intervention. Conclusion: It can be concluded from the study that pumpkin seed capsules affected the decrease of uric acid level significantly, but the number was lower compared to allopurinol. In future studies, The dose of pumpkin seed should be considered.

Published: August 2024

Background: Sanctions against a country could be a shock to the country's economy for a specific period. Iran has been subject to various sanctions for the past 40 years, and these sanctions have intensified since 2011. Unprecedented sanctions were imposed on Iranians after the United States withdrew from the Joint Comprehensive Plan of Action (JCPOA) agreement, and a disastrous economic situation was the outcome of this international issue. The present study aims to evaluate the impact of this situation on weight gain of pregnant mothers and birth weight as well as food security of their families. Methods: The data of pregnant women and newborns were extracted from Sina Electronic Health System (SinaEHR®) questionnaires. These questionnaires were completed by trained healthcare workers in comprehensive health service centers. The data of 266,182 pregnant women were collected through questionnaires from 19 comprehensive health centers related to Razavi Khorasan province and were prepared for statistical analysis.

Published: August 2024

Background: Bambara nut, an underutilized legume is rich in protein and can improve the nutritional quality of snacks. This study evaluates the nutritional and sensory properties of muffins produced from germinated maize and Bambara groundnut flours. Methods: Maize and Bambara groundnut seeds were germinated (72 hours), oven-dried and milled. The composite flours from the germinated flours were combined with soya oil, tiger-nut milk, date and carrot powder to produce four samples of muffins. The samples were chemically analyzed for proximate, mineral, beta-carotene, and anti-nutrient contents. Then, sensory evaluation was carried out among 20 mothers (20-30) using a 5 hedonic scale. ANOVA and Duncan Multiple Range Test were also used to analyze the data. Results: Protein, fiber and carbohydrate contents of the muffins ranged from 7.63-9.23%, 0.05-0.08% and 70.63-71.55%, respectively. It was found that germination significantly increased protein and iron content of muffins but reduced zinc, calcium, and beta-carotene contents (P<0.001). The muffins contributed above 22% of the RDA regarding energy for children. Muffins produced from the blends provided higher level of protein, calcium, iron and beta-carotene compared to those made from whole wheat flour. There was a significant reduction in anti-nutrient contents of the muffins and germinated flours. The muffin produced from the 80% maize and 20% Bambara nut flour was rated best in terms of nutritional value, taste, and texture. Conclusion: Bambara nut flours could be used to produce nutritious snacks which would contribute to daily energy and protein needs of children.

Digital Image Colorimetric Detection of H2O2 Utilizing PEG/Ag/AgO Nanoparticles Derived from Tangerine Leaf Extract
Authors: Yılmazoğlu Emre
Published: August 2024

Recent developments in biosensors based on digital platforms have primarily focused on enhancing rapid detection, flexibility, and selectivity through the utilization of nanomaterials. Despite these advances, the complexity of image colorimetric measurements continues to be a subject of interest. This study focused on the development of a new digital image colorimetric biosensor for real-time quantification of hydrogen peroxide (H2O2). The designed nanostructure-based sensor showed excellent selectivity and sensitivity, utilizing polyethylene glycol/Silver/Silver(II) oxide nanoparticles obtained from tangerine leaf extract (TLE/PEG/Ag/AgO NPs). The sensor's performance was validated using Ag/AgO NPs derived from tangerine leaf extract (TLE), demonstrating remarkable selectivity and sensitivity using a Red-Green-Blue (RGB)--based approach. Based on digital image colorimetric measurements of TLE/PEG/Ag/AgO NPs, a system for determining H2O2 was established in a linear range of 2.0–100.0 μmol/L with a low limit of detection (LOD) of 1.82 μmol/L. This study not only presented a facile strategy for the design of the digital image colorimetric TLE/PEG/Ag/AgO NPs-based biosensor but also shed light on the remarkable potential of smartphone sensing devices based on nanosensor technology. These sensors offer fresh perspectives and multidisciplinary approaches to visually sensitive sensing in a range of applications, such as biomedical diagnostics, security screening, and environmental monitoring.

Recreational Therapy Support Group Framework: Insights from a Personal Cancer Journey Authors
Authors: Dawson Shay
Published: August 2024

The need for social support groups that address the quality of life of individuals experiencing illness or disability are lacking (Lyons et al., 1995). At the same time, there has been a call for the development of recreation therapy support programs that has gone unanswered for over two decades (Austin, 2002). Further evidence of the need for a program framework in recreation therapy is evidenced by the growing body of literature calling for leisure- based support programs as an adjunct to traditional approaches (Dawson & Mowatt, 2022; Lock, 2010; Myers et al., 2011; Shannon & Bourque, 2005). Taken together, there is a strong need for the development and empirical testing of a recreation therapy based social support group framework to guide clinical practice. The following health narrative highlights the author’s personal journey with cancer and subsequent insights on social support, social comparisons in illness, spirituality, and post traumatic growth as vital components to social support programming.

Authors: Koplin Lori , Perez Tania Santiago
Published: August 2024

Nurturing self-determination, promoting intrinsic motivation, and exercising control of their lives should be important outcomes of sport programs for people with intellectual and developmental disabilities. This protocol presents Pickle Squad, a pickleball recreational therapy intervention for eight adolescents and young adults with intellectual and developmental disabilities delivered by a Certified Therapeutic Recreation Specialist (CTRS®). The purpose of Pickle Squad was to cultivate the participants’ self-determination and promote the development of sport-specific pickleball skills; this small group intervention applied the recreational therapy process (i.e., APIED) in the delivery of an 8-session program. Each participant completed one pickleball skills assessment and one self-determination assessment pre and post intervention. Individual and group goals and objectives were developed for participants. Each session lasted two hours and started with lessons and activities focused on self-determination, followed by lessons and drills targeting pickleball skills, and concluded with processing. Progress notes were documented for each participant. Evaluation results via single sample t-tests revealed that overall participants increased their self-determination t(7) = 2.61, p = .035. and developed sport-specific pickleball skills, t(7) = 4.77, p = .00. By conventional criteria, t-test results obtained were statistically significant. A discussion with limitations and implications for practice and research is included. In conclusion, this protocol suggested that self-determination levels could be increased through a pickleball intervention focused on self-determination and sport-specific pickleball skills.

Authors: Westenskow Rebecca , Nelson Rhonda
Published: August 2024

This study examined the feasibility of implementing an adaptive biking program to concurrently address health and well-being in assisted living memory care residents and staff. Using an intervention protocol designed around the Flourishing Through Leisure Model, resident and staff participants were matched into biking pairs to engage in eight 20-30 minute bike rides over four consecutive weeks. The research team assessed (a) recruitment capability and sample characteristics, (b) data collection procedures and outcome measures, (c) acceptability and suitability of the intervention and study procedures (d) resources and ability to manage and implement the study and intervention, and (e) preliminary participant responses to the intervention. Results in each area support the feasibility of implementation on a larger scale and provide insights for program improvements and research opportunities. Given the lack of structured intervention protocols that emphasize multiple domains of health for two populations concurrently, the study also documented a replicable RT adaptive biking protocol designed to meet the needs of both staff and residents. Implications for RT practice include increased awareness of the value of RT services among other health care providers, and new opportunities for interprofessional collaboration.

Published: August 2024

Background: The use of antimicrobials in food animals significantly contributes to the development of antimicrobial resistance in nature. This study aimed to determine the prevalence of ESBL-producing E. coli isolated from cattle, buffalo, sheep and goat fecal samples. Methods: In this study out of 2025 healthy animals from 10 different farms, fecal samples were randomly collected by rectal swabs from 200 animals (50 each from cattle, buffalo, sheep and goat). E. coli was isolated and further studied for AMR and ESBL production by phenotypic assays and PCR targeting ESBL genes. Result: The overall prevalence of E. coli was 81.50% with the highest isolation rate from cattle and goat samples. Out of 163 isolates, 45.39% were ESBL-producers. Genes encoding beta-lactam resistance viz. blaSHV, blaTEM, blaCTX-M and blaOXA were detected in 44.59% ESBL-positive isolates. The blaSHV was present in only cattle isolates, while blaCTX-M was present in E. coli isolated from all animals. The prevalence of beta-lactam genes was found as blaSHV (2.70%), blaTEM (12.16%), blaCTX-M (22.97%) and blaOXA (6.75%). A high degree of resistance to multiple antimicrobials was observed. Maximum susceptibility of E. coli was observed for trimethoprim, imipenem and chloramphenicol. This study demonstrated that food animals could be the source of ESBL-producing multidrug-resistant E. coli. The present findings are significant in the context of AMR monitoring in India.

Pasirtanjung village has many young people who have an essential role in the village. However, although the number of youths is quite large, the Karang Taruna in Pasirtanjung Village is still unable to function optimally because members are not active enough to contribute. Therefore, Karang Taruna does not function like a youth organization. Meanwhile, to make the organization function optimally (achieve its goals), it is necessary to have contributions from each member. Community service activities are designed to build a better village community, in this case, Karang Taruna. This activity resulted in a program to improve team building for youth organizations. This is done to strengthen teamwork, improve group performance, and increase emotional attachment between group members and trust between members. Moreover, it optimizes the role of Karang Taruna in achieving its goal as one of the community institutions that helps build the village. The first step in building team building is strengthening group cohesiveness within the youth organization.A series of programs were designed to improve team building: 1) providing materials, 2) training, and 3) Focus group discussions. These team-building activities have been proven to help improve group performance. Systematic team-building activities can increase emotional attachment between group members and trust between members. This series of activities can ultimately be measured through pretest-posttest measurements related to group cohesion. The results show that the understanding of youth regarding group cohesion in youth organizations has increased after being given training. This training can provide new insights to the trainees that developing an organization requires an active and mutually supportive team.

Published: August 2024

The Lembak gas field, situated within the South Sumatra Basin, Indonesia, has been a focal point of hydrocarbon extraction, primarily targeting the Baturaja carbonate as the main reservoir. However, recent drilling activities have highlighted challenges associated with the lower segment of the Baturaja Formation (BRF). Notably, this transition zone exhibits porous characteristics, which have led to partial or total loss of circulation during drilling operations. These unexpected porous features in the lower BRF carbonate complicate the drilling process, prompting the need for a refined approach to ensure operational efficiency and safety. This study aims to address these challenges by leveraging pore pressure and fracture gradient analysis to optimize casing point design, particularly focusing on the upper Talang Akar Formation (TAF) sand layer as a potential solution.
What Do Oil Rig Trainees Think About How Drilling Simulations Affect their Motivation and Ability to Learn?
Authors: Abdelaziz Adel M. H.
Published: August 2024

The lack of sufficient enrollment in vocational drilling training programs has led to a shortage of skilled workers, resulting in difficulties in recruiting and retaining national crews for drilling rigs. Utilizing state-of-the-art simulation technology will enhance the rig crew and trainees’ productivity, educational progress, motivation, and accomplishments. A basic qualitative study investigated the impact of simulation technologies on trainees’ learning, motivation, and viewpoints regarding their education at the vocational training facility for oil-field drilling rigs. The conceptual framework for user reception of information systems was based on Davis's technology acceptance model. Ten drilling crew trainees were selected for semistructured virtual interviews. Subsequently, the data was transcribed, and a manual process of descriptive coding was employed to discover five themes that directly addressed the research topics. Five distinct patterns were identified via the process of analyzing the data. The initial three themes encompassed the simplicity and practicality of teaching drilling application skills through simulator technology. The next two themes were the manner in which the use of the drilling simulator motivated and instilled a sense of enthusiasm in the trainees, hence fostering their inclination to conclude their studies successfully. The study's results demonstrated that using drilling simulators in training proved highly advantageous. It facilitated the establishment of a practical training setting that was secure, economically efficient, and user-friendly. The training familiarized the trainees with the operation and handling of various rig equipment and tools. It enhanced the trainee's drilling and well control skills, increasing their working experience. Additionally, it facilitated the trainees’ experience of challenging scenarios related to different operations and fostered a sense of teamwork. This contributed to a decrease in the rig's non-productive time. The study's findings could provide valuable insights to executives of drilling contractor training facilities regarding the significance of expanding drilling simulation methods to encompass all potential drilling job activities. Drilling simulators can foster beneficial societal transformation among trainees, the drilling rig personnel, and the regional community by enhancing their knowledge and comprehension of drilling procedures.

Eutrophication Resistance and Microbial Nitrogen Removal in South San Francisco Bay
Authors: Czapla Kenneth , Owens Michael S , Cornwell Jeffrey C , Senn David B , Francis Christopher A , Chelsky Ariella
Published: August 2024

The ecosystem response to anthropogenic nitrogen (N) loading in estuarine systems is determined by hydrodynamics, biogeochemical transformation rates, and other system-specific characteristics. Historically, San Francisco (SF) Bay has been an outlier from other estuaries with an unusual resistance to eutrophication, despite having extremely high rates of nitrogen loading. Recent increases in phytoplankton biomass and an unprecedented harmful algal bloom, however, have increased the urgency to understand rates and drivers of nitrogen removal in the system. To assess benthic N cycling rates, we conducted seasonal measurements across nine sites in South and Lower South SF Bay, the two sub-embayments with the highest rates of areanormalized N loading, to determine the rates and potential drivers of denitrification and dissimilatory nitrate reduction to ammonium (DNRA). Denitrification rates averaged 60.6 ± 8.1 µmol m-2 hr-1 and were primarily coupled to nitrification. Denitrification rates were positively correlated with DNRA rates and % clay. DNRA rates ranged from 0 to 20 µmol m-2 hr-1 and on an annual basis averaged ~10% of total benthic nitrate reduction, with a negative correlation to % clay content in the surface sediment. The measured denitrification rates account for the removal of, on average, 14% of N loaded annually to South SF Bay, leaving a sizeable portion for alternate fates (e.g, recycling, export, or burial) and potential for substantial temporal and spatial variability (1-79%). This identifies the relative importance of sediment denitrification in ecosystems characterized by high nutrients and low productivity.

Chinese ethnic minorities, including the Daur, Evenki, and Oroqen, living in the Amur River Basin, may have biologically adapted to extreme cold, but the genetic basis of such adaptations remains underinvestigated. Here, we conducted the first whole-genome sequencing study of 90 individuals representing the three groups to gain insights into their genetic structure, population history, and potential cold adaptation. We observed both shared and differentiated natural selection signatures associated with cold adaptation among these populations. Notably, we identified several novel cold adaptation genes, including FGGY, ADH1A, ADH1B, and NELL1, and noted an independent selection event on alcohol dehydrogenase genes, distinguishing these populations from East Asians south of the Amur River. Furthermore, we modeled the evolutionary scenarios of adaptive alleles for each population. Our findings advance the understanding of human adaptation to cold stress and the demographic history of populations in ultracold regions.
Mutagenesis combined with 2-deoxyglucose is not a suitable tool to select strains of Papiliotrema laurentii less sensitive to glucose catabolite repression

Published: August 2024

Assimilation of major sugars from lignocellulosic biomasses is pivotal for achieving a feasible oil production by oleaginous yeasts in biorefineries. Papiliotrema laurentii UFV-1 is an oleaginous yeast capable of converting lignocellulosic sugars such as glucose and xylose into lipids; however, glucose is assimilated before xylose, impairing high volumetric lipid productivity. To circumvent this drawback, we hypothesized that random mutagenesis combined with 2-deoxyglucose (2DG) selection would be a suitable strategy for selecting strains of P. laurentii UFV-1 less sensitive to glucose repression. First, we determined the growth kinetics parameters of the wild strain in minimum medium with glucose and/or xylose. Then, the yeast was subjected to mutagenesis by ultraviolet irradiation, and mutants were selected in a culture medium containing 2DG. Among the 24 selected mutants, the M17 strain stood out due to its capacity to achieve a higher cell density at the 2DG inhibitory concentration. Surprisingly, both M17 and wildtype strains presented the same xylose and glucose consumption profile. Although M17 grew faster in xylose and preserved the oleaginous phenotype, it could not co-assimilate glucose and xylose. Interestingly, the tolerant strain grew assimilating 2DG and xylose simultaneously, likely incorporating 2DG into its biomass. Otherwise, the wild strain presented arrested growth and only grew after exporting 2DG back to the media. Since carbon catabolite repression and 2DG response mechanisms are poorly studied and remains elusive in Basidiomycota yeasts, we provided cues to guide future studies that will allow a better understanding of the mechanisms involved with 2DG resistance in these yeasts.

Published: August 2024

Background
Performance optimization is a major goal in sports science. However, this remains difficult due to the small samples and large individual variation in physiology and training adaptations. Machine learning (ML) solutions seem promising, but have not been tested for their capability to predict performance in this setting. The aim of this study was to predict 4-km cycling performance following a 12-week training intervention based on ML models with predictors from physiological profiling, individual training load and well-being, and to retrieve the most important predictors. Specific techniques were applied to reduce the risk of overfitting.
Results
Twenty-seven recreational cyclists completed the 4-km time trial with a mean power output of 4.1 ± 0.7 W/kg. Changes in time-trial performance after training were not different between moderate-intensity endurance training (n = 6), polarised endurance training (n = 8), concurrent polarised with concentric strength training (n = 7) and concurrent polarised with eccentric strength training (n = 6) groups (P > 0.05), but included substantial inter-individual differences. ML models predicted cycling performance with excellent model performance on unseen data before (R2 = 0.923, mean absolute error (MAE) = 0.183 W/kg using a generalized linear model) and after training (R2 = 0.758, MAE = 0.338 W/kg using a generalized linear model). Absolute changes in performance were more difficult to predict (R2 = 0.483, MAE = 0.191 W/kg using a random forest model). Important predictors included power at V̇O2max, performance V̇O2, ventilatory thresholds and efficiency, but also parameters related to body composition, training impulse, sleep, sickness and well-being. Conclusion
ML models allow accurate predictions of cycling performance based on physiological profiling, individual training load and well-being during a 12-week training intervention, even using small sample sizes, although changes in cycling performance were more difficult to predict.

Human daily activities and businesses generate a high volume of data which are expected to be transformed for the benefit of businesses and mankind. Organizations make use of machine learning platforms to make informed decisions from well gleaned insights of their real-time data. The process of learning machine learning is seemingly not an easy one, making it tedious for employees to learn easily and quickly. Meanwhile, the introduction of automated machine learning (AutoML) has made this easier. However, it is essential to understand how users embrace and implement the AutoML platform for their real-world problems. To achieve this, we conducted a quantitative study with 38 users focusing on understanding firstly, the learning curve (i.e. the alignment of users’ performance proportionately with the time required to complete a given machine learning task at any given time) and experience of people in the process of learning machine learning. Secondly, the strengths and weaknesses in the design and usability of ML and AutoML. Thirdly, the gaps in the usage or user experience of a newbie - an inexperienced or fresh entrant in the machine learning domain- an inexperienced and fresh entrant in the machine learning domain and professionals, and fourthly, the design factors needed to improve the user experience. Our findings revealed that users have high expectations in the usability of AutoML. In this study, we were able to carry out an assessment of awareness rate of AutoML among the respondents, users’ learning curve in AutoML environment, usability assessment as it relates to variations in users of AutoML, human computer interactivity in relation to in terms of user centeredness and experience of the environment. The study revealed the level of awareness, reasons for apathy and some usability concerns begging for improvement to attract a high rate of usefulness and adoption. In the near future, we hope to take this work further by engaging frequent users of various AutoML environments to ascertain the level of satisfaction using such platforms and identify areas of concern.

Reduction gears, especially those with fewer gears similar to the three-ring reducer, can cause changes in the gap between gear teeth due to wear of the tooth surfaces during the application process. The dynamic variation of the gear tooth gap adds nonlinear factors to the dynamic behavior of the engagement process, thus complicating its dynamic behavior and leading to increased vibration and wear, which affects the expansion of the application of fewer gears in the aerospace field. To solve this problem, the aeronautical three-ring gear reducer with fewer gears is taken as the research object, the tooth surface state at different wear stages is considered, the Weierstrass-Mandelbor function is introduced to describe the tooth surface morphology and the time-varying tooth flank gap is calculated, a bending-torsion coupled Six-degree-of-freedom nonlinear vibration model is established. Using the fractal dimension of the Weierstrass-Mandelbor function to describe the state of the tooth surface at different wear stages and the dynamics of aviation three-ring reducer with small tooth difference is analyzed, with the increase of fractal dimension under the same initial conditions, the gear transmission system changes from quasi-periodic motion state to chaotic motion state. By considering the influencing factors of torque and rotational speed, the nonlinear dynamic behaviors at different wear stages are analyzed. The results show that as the rotational speed increases, the system response cycle exhibits a chaotic-proposed cycle-chaotic law of motion. As the torque increases, the system responds to periodic processes now chaotic-hypothetical periodic laws of motion. The findings of the study can effectively support the vibration and noise reduction of the three-ring reducer and provide a theoretical basis for the expansion of its application in the aerospace field.
Tax reform when commuting has demerit properties

People spend a lot of their time commuting. Research in health economics indicates that spending time in traffic has long run adverse mental and physical health consequences. Literature suggests that, when making decisions about commuting, the individual might underestimate these long run consequences and take them insufficiently into consideration. For this reason, we argue that commuting has demerit properties: an internality is involved. From a social welfare perspective, apart from the demerit aspect, commuting is also associated with an externality. If commuters underestimate the impact on their welfare of commuting, this aggravates also the externality. We develop a formal model incorporating both the externality and the internality aspects of commuting, and its interplay. From the model we derive clearly two types of externalities: direct and indirect ones, both of which need internality correction. Then we incorporate both these considerations into marginal costs of funds (MCF) formulae. MCF are calculated for all U.S. states using the American Time Use Survey. We show that the demerit considerations cause rank switches in over half of the States and that an increase in the taxes on commuting accompanied by a decrease in other taxes benefits social welfare.

Background: Chromosome organization plays an important role in biologicalprocesses such as replication, regulation, and transcription. One way to study therelationship between chromosome structure and its biological functions is through Hi-C studies, a genome-wide method for capturing chromosome conformation.Such studies generate vast amounts of data. The problem is exacerbated by thefact that chromosome organization is dynamic, requiring snapshots at differentpoints in time, further increasing the amount of data to be stored. We present anovel approach called the High-Efficiency Contact Matrix Compressor (HiCMC)for efficient compression of Hi-C data.
Results: By modeling the underlying structures found in the contact matrix,such as compartments and domains, HiCMC outperforms the state-of-the-artmethod CMC by approximately 8% and the other state-of-the-art methods cooler,LZMA, and bzip2 by over 50% across multiple cell lines and contact matrixresolutions. In addition, HiCMC integrates domain-specific information into thecompressed bitstreams that it generates, and this information can be used tospeed up downstream analyses.
Conclusion: The HiCMC is a novel compression approach that utilizes intrinsicproperties of contact matrix, such as compartments and domains. It allows fora better compression in comparison to the state-of-the-art methods. HiCMC isavailable at https://github.com/sXperfect/hicmc.
