Published: April 2024

Introduction: The aim of this study was to examine the effects of foam rolling (FR) on hamstring muscles stiffness in both non-damaged and exercise-induced muscle damage (EIMD) states, using shear wave ultrasound elastography to measure changes in shear modulus.Methods: Fourteen healthy adults (25.5 ± 4.7 years) participated in a within-participant repeated measures design, with a 2-minute FR intervention applied on one leg and contralateral leg serving as a control. The damaging protocol encompassed maximal eccentric knee extensions performed on an isokinetic dynamometer and the Nordic hamstring exercise, consisting of 3 sets of 10 and 6 repetitions, respectively. Measurement were taken at baseline and then 1 h, 24 h and 48 h after the damaging protocol.Results: The results indicated no significant time × leg interaction for shear modulus in biceps femoris, semimembranosus, and semitendinosus muscles in both non-damaged and damaged states. Notably, there was a significant increase in biceps femoris (p = 0.001; η2 = 0.36) and semitendinosus (p &lt; 0.001; η2 = 0.44) shear modulus after EIMD, but no significant differences were found between the FR and control leg, which was also the case for muscle soreness, range of motion, and passive resistive torque (p = 0.239–0.999 for interactions).Discussion: The absence of significant changes post-FR intervention suggests a limited role of short-duration FR in altering muscle stiffness during recovery from EIMD. These findings contribute to the understanding of FR’s role in muscle recovery. Although this was not directly investigated, our results suggest a predominance of central mechanisms rather than direct mechanical modifications in muscle properties. This research highlights the necessity for additional investigations to explore how FR interventions influence muscles in different states and to elucidate the mechanisms underlying these influences.

BackgroundNowadays, e-learning significantly affects college students’ academic life. This study aims to examine the factors that influence college students’ satisfaction with online learning outcomes.MethodThe study population consisted of undergraduate students from Dalian Medical University, with a total of 715 college students participating in the study. Out of these participants, 602 valid questionnaires were obtained. Demographic data was analyzed using SPSS.22, and the data was cleaned and prepared for testing the research hypotheses. The proposed research framework was examined using structural equation modeling (SEM) through Smart-PLS 3.0.ResultsThe results of the study showed that student satisfaction with learning outcomes was positively correlated with several factors: quality of teacher instruction (β = 0.100, p &lt; 0.0001), quality of e-learning platforms (β = 0.059, p &lt; 0.0001), individual learner factors such as learning motivation (β = 0.112, p &lt; 0.001), and e-learning environment (β = 0.469, p &lt; 0.001). Additionally, self-learning efficacy (β = 0.081, p &lt; 0.0001), learning strategies (β = 0.031, p &lt; 0.001), and learning motivation (β = 0.039, p &lt; 0.001) were found to have mediating effects.ConclusionUnderstanding the satisfaction of college students with the effect of e-learning holds great significance in coping with teaching methods in unexpected situations. It enables adjustments to teaching strategies, improvements to learning platforms, and mobilization of students’ motivation. Thus, it serves as a valuable reference in addressing unexpected teaching scenarios.

Published: April 2024

BackgroundThis study aims to determine how workplace violence experienced by healthcare workers in Turkey affects their job satisfaction and intention to leave. It also examines the mediating role of employees’ work-family conflict between these effects.MethodsThe PROCESS method was used in the study. The research was conducted on 595 health workers in three public hospital affiliated with the Istanbul Provincial Health Directorate. The convenience sampling method was used in the selection of the participants.ResultsAs a result of the analysis, it was determined that there is a positive, significant, moderate (R = 0.35, p &lt; 0.01) relationship between workplace violence and work-family conflict, and a negative, significant and weak relationship between workplace violence and job satisfaction (R = −0.27, p &lt; 0.01), there is a positive, significant, and weak (R = 0.26, p &lt; 0.01) relationship between workplace violence and intention to leave. In addition, there is a negative, significant, and weak (R = −0.27, p &lt; 0.01) relationship between work-family conflict and job satisfaction, and a positive, significant, and weak (R = 0.28, p &lt; 0.01) relationship between work-family conflict and intention to leave. Workplace violence had significant and negative effects on the employees’ job satisfaction and significant and positive effects on the intention to leave and work-family conflicts.DiscussionAs a result of the mediating variable analysis, it was determined that work-family conflict has a partial mediator role in the relationship between workplace violence, job satisfaction, and intention to leave. The results are very important, especially for managers working in the healthcare sector. Reducing workplace violence against healthcare personnel will contribute to increasing productivity in the sector and providing better quality service to the healthcare sector.
Mendelian randomization analyses for the causal relationship between early age at first sexual intercourse, early age at first live birth, and postpartum depression in pregnant women
Authors: Zhao Xuemin , Liu Linfei 
Published: April 2024

IntroductionThere are insufficient epidemiological studies on the impact of age at first sexual intercourse (AFS) and age at first live birth (AFB) on postpartum depression (PPD) in pregnant women, and the conclusions of these studies are inconsistent.MethodsWe performed a Mendelian randomization (MR) study to determine the causal relationship between AFS or AFB and the risk of PPD. The summary data were extracted from genome-wide association study (GWAS) summary datasets. We selected the instrumental variables according to the P value of exposure-related single nucleotide polymorphisms (P&lt;5 ×10-9 for AFS and P&lt;5 ×10-8 for AFB) and estimated the linkage disequilibrium using the clump parameter (10,000 kb, r2 &lt; 0.001). Single nucleotide polymorphisms were considered instrumental variables that were significantly associated with exposure factors without linkage disequilibrium. The F-statistics of the instrumental variables should all be larger than 10. A random-effects model of IVW was constructed as the main method in our study.Results and discussionMR studies based on GWAS data revealed that both AFS (OR = 0.4, P &lt;0.001) and AFB (OR = 0.38, P &lt;0.001) were negatively correlated with the risk of PPD. Early AFS and early AFB should be studied as possible risk factors for PPD in the future. Public health departments should attach importance to sex education for young girls. The results of our TSMR should be verified by high-quality prospective epidemiological studies in the future.

Published: April 2024

IntroductionResearch has indicated that individuals diagnosed with bipolar disorder (BD) might experience alterations in their olfaction or levels of serum tumor necrosis factor-α (TNF-α), but no studies have investigated olfactory function and serum TNF-α in BD patients simultaneously. Moreover, there is a lack of existing research that compares the longitudinal olfactory function between individuals with manic and euthymic BD I.MethodsPatients with manic BD I (BDM, n=44) and healthy controls (HCs, n=32) were evaluated symptoms (measured via the Young Manic Rating Scale, YRMS), social function (measured via the Global Assessment Function, GAF), serum TNF-α, and olfactory function (via the Sniffin’ Sticks test) including olfactory sensitivity (OS) and olfactory identification (OI). The BDM patients were followed up to the remission period and re-evaluated again. We compared OS, OI and serum TNF-α in manic and euthymic patients with BD I and HCs. We examined the correlation between olfactory function and symptoms, social function, and serum TNF-α in patients with BD I.ResultsThe BDM patients exhibited significantly lower OS and OI compared to the HCs (Z = −2.235, P = 0.025; t = −6.005, P &lt; 0.001), while a positive correlation was observed between OS and GAF score (r = 0.313, P = 0.039). The OS in the BD I remission group (n=25) exhibited significantly superior performance compared to the BDM group (t = −4.056, P &lt; 0.001), and the same as that in the HCs (P = 0.503). The change in OS showed a positive correlation with the decrease in YMRS score (r = 0.445, P = 0.026), and a negative correlation with the course of disease (r = -0.594, P = 0.002). The TNF-α in BD I patients was significantly lower compared to HCs (P &lt; 0.001), and not significantly correlated with olfactory function (all P &gt; 0.05).ConclusionThe findings suggest that OS and OI are impaired in BDM patients, and the impaired OS in those patients can be recovered in the remission stage. OI may serve as a potential characteristic marker of BD. OS might be useful as an index for BDM treatment efficacy and prognosis.

ObjectivesThe primary objective was to determine whether obliteration of the epitympanic area and mastoid cavity during canal wall up (CWU) cholesteatoma surgery reduces the rate of recurrent and residual cholesteatoma compared to not obliterating the same area. The secondary objective was to compare postoperative hearing outcomes between both techniques.MethodsA retrospective cohort study was conducted in a tertiary referral center. One-hundred-fourty-three ears were included of patients (≥18y) who underwent a CWU tympanomastoidectomy for cholesteatoma with or without bony obliteration between January 2015 and March 2020 in the University Medical Center Utrecht. The median follow-up was respectively 1.4 (IQR 1.1–2.2) vs. 2.0 years (IQR 1.2–3.1) (p = 0.013).Intervention(s)All patients underwent CWU tympanomastoidectomy for cholesteatoma. For 73 ears bone dust, Bonalive® or a combination was used for obliteration of the mastoid and epitympanic area, the rest of the ears (n = 70) were not obliterated. In accordance with the Dutch protocol, included patients are planned to undergo an MRI scan with diffusion-weighted imaging (DWI) one, three and five years after surgery to detect recurrent or residual cholesteatoma.Main outcome measure(s)The primary outcome measure was recurrent and residual cholesteatoma as evaluated by MRI-DWI and/or micro-otoscopy and confirmed by micro-otoscopy and/or revision surgery. The secondary outcome measure was the postoperative hearing.ResultsIn this cohort, the group treated with canal wall up tympanomastoidectomy with subsequent bony obliteration (73 ears, 51.0%) had significantly lower recurrent (4.1%) and residual (6.8%) cholesteatoma rates than the group without obliteration (70 ears, 25.7% and 20.0%, respectively; p &lt; 0.001). There was no significant difference between both groups in postoperative bone conduction thresholds (mean difference 2.7 dB, p = 0.221) as well as the mean air-bone gap closure 6 weeks after surgery (2.3 dB in the non-obliteration and 1.5 dB in the obliteration group, p = 0.903).ConclusionsBased on our results, a canal wall up tympanomastoidectomy with bony obliteration is the treatment of choice, since the recurrent and residual disease rate is lower compared to the group without obliteration. The bony obliteration technique does not seem to affect the perceptive or conductive hearing results, as these are similar between both groups.

Platonia insignis is a fruit tree native to Brazil of increasing economic importance, with its pulp trading among the highest market values. This study aimed to evaluate the structure and genomic diversity of P. insignis (bacurizeiro) accessions from six locations in the Brazilian States of Roraima, Amazonas, Pará (Amazon biome), and Maranhão (Cerrado biome). A total of 2031 SNP markers were obtained using genotyping-by-sequencing (GBS), from which 625 outlier SNPs were identified. High genetic structure was observed, with most of the genetic variability (59%) concentrated among locations, mainly between biomes (Amazon and Cerrado). A positive and significant correlation (r = 0.85; p < 0.005) was detected between genetic and geographic distances, indicating isolation by distance. The highest genetic diversity was observed for the location in the Cerrado biome (HE = 0.1746; HO = 0.2078). The locations in the Amazon biome showed low genetic diversity indexes with significant levels of inbreeding. The advance of urban areas, events of burning, and expansion of agricultural activities are most probably the main factors for the genetic diversity reduction of P. insignis. Approaches to functional analysis showed that most of the outlier loci found may be related to genes involved in cellular and metabolic processes.
Bipartite (P6,C6)-Free Graphs: Recognition and Optimization Problems
Authors: Quaddoura Ruzayn , Al-Qerem Ahmad 
Published: April 2024

The canonical decomposition of a bipartite graph is a new decomposition method that involves three operators: parallel, series, and K⨁ S. The class of weak-bisplit graphs is the class of totally decomposable graphs with respect to these operators, and the class of bicographs is the class of totally decomposable graphs with respect to parallel and series operators. We prove in this paper that the class of bipartite (P6,C6)-free graphs is the class of bipartite graphs that are totally decomposable with respect to parallel and K⨁S operators. We present a linear time recognition algorithm for (P6,C6)-free graphs that is symmetrical to the linear recognition algorithms of weak-bisplit graphs and star1,2,3-free bipartite graphs. As a result of this algorithm, we present efficient solutions in this class of graphs for two optimization graph problems: the maximum balanced biclique problem and the maximum independent set problem.

Published: April 2024

Some processing techniques tend to advance the overall nutritional quality of food commodities and thus may contribute to counter malnutrition in regions like Tharparkar. For scanning the efficacy of some selected processing treatments, the natural vegetation of Tharparkar (NVT) i.e., mung beans (MB), sesame seeds (SS), and pearl millet (PM), were sprouted, roasted, and blanched, respectively, and milled to flour after thermal drying. All fresh and processed NVT, i.e., sprouted mung bean flour (SMBF), roasted sesame seed powder (RSSP), and blanched pearl millet flour (BPMF), were analyzed for proximate composition, profiling of amino acids (AAs), and safety assessment. The results demonstrated statistically different (P<0.05) mean values of fresh and processed NVT for most of the analyzed parameters. It was found that processing significantly increased (P<0.05) ash, protein, fat, and fiber content whereas significantly decreased (P<0.05) phytic and oxalic acid in the NVT. In addition, some essential AAs significantly (P<0.05) enhanced in SMBF i.e., histidine (0.45g/100g), isoleucine (0.59g/100g), lysine (0.71g/100), methionine (0.23g/100g), phenylalanine (1.54g/100g), and valine (0.32g/100g); RSSP i.e., isoleucine (1.63g/100g), leucine (4.57g/100g), lysine (0.75g/100g), phenylalanine (3.14g/100g), tryptophan (0.81g/100g), and tyrosine (2.15g/100g); and in BPMF i.e., threonine (0.55g/100g), isoleucine (0.28g/100g), leucine (1.70g/100g), methionine (0.21g/100), tryptophan (0.11g/100g), and valine(0.17g/100g). Among non-essential AAs, the alanine and glycine remained significantly higher (P<0.05) in all processed NVT i.e., 1.56, 1.29, and1.43g/100g alanine in SMBF, RSSP, and BPMF, respectively. However, glycine remained at 0.56, 0.59, and 0.23g/100g in SMBF, RSSP, and BPMF, respectively. It is therefore concluded that processing techniques exerted a significant role in enhancing nutritional profile while mitigating the antinutrient load from the NVT. Consequently, it is recommended that SMBF, RSSP, and BPMF be utilized for developing various food products to counter malnutrition in regions like Tharparkar.

Abstract
A low-energy femtosecond (fs) pulsed laser was utilized to ablate the Nd:YAG laser crystal target in high-pressure oxygen (O2) and nitrogen (N2) background gases. Only minute amounts of neodymium (Nd), yttrium (Y), and aluminum (Al) were detected in the deposited material due to the thermalization resulting from low laser pulse energy and significant scattering caused by the high background gas pressure. We used a collision-based model and peak-fitting method of the angular distribution of the plume to explain the result. The collision-based model was used to explain and determine the probability distribution of the elements arriving from the target to the substrate. The magnitude of the probability distribution obtained with O2 background gas is higher as compared to N2 background gas owing to the former’s higher collision frequency. The peak-fitting method of the angular distribution of Nd, Y, and Al provided better approximations of the ratio of atoms arriving after ablation as compared to the collision-based model. Further improvements can be carried out to better predict the deposited material ratio.

ABSTRACT
Few Brazilian rural landowners are aware of the technology available to survey the subsoil of terrains earmarked for aquaculture operations. This study evaluated subsoils of Monte Alegre (area 1) and Montenegro 3 (area 2) aquaculture zones in the geographic region of Bragança (Amazon region, northern Brazil), and the adequacy of these areas for aquaculture. Ground Penetrating Radar, electrical conductivity measurements, and sedimentological analyses were applied to evaluate the subsoil of fish farms. Apparent conductivity values recorded by the Electromagnetic Induction (EMI) in area 1 indicated possible presence of clayey soils. Excavation analysis and sedimentological samples (sand) from this site confirmed the inadequacy of the terrain. The EMI tool in area 2 indicated possible presence of clayey soils. Geophysical and sedimentological results from the site confirmed its suitability. These geophysical tools are recommended for evaluating prospective aquaculture sites, given their capacity to provide reliable data on the subsoil characteristics , which is essential to guarantee the success and sustainability of aquaculture operations.
