Acute Effects of Soleus Stretching on Ankle Flexibility, Dynamic Balance and Speed Performances in Soccer Players

Simple Summary Calf muscles, including the gastrocnemius and soleus muscles, are very important for soccer players, but the benefits of soleus stretching are rarely reported. Both regular and soleus stretching conditions lead to better ankle range of motion, maximum plantarflexion strength, dynamic balance and speed performances compared to the no-stretching control. Adding soleus stretches into the regular stretching protocol would allow further improvement of ankle flexibility, maximum plantarflexion strength and curved running speed performances. The results from this study can provide insights for pre-exercise design and subsequent performances in soccer. Abstract Most dynamic stretching protocols include the gastrocnemius muscle, but soleus stretches are often neglected, which is the key powerful muscle for the push-off (concentric) of all speed movements. The purpose of this study was to examine whether the added soleus stretch in a regular stretching protocol would have greater benefits for ankle flexibility, dynamic balance and functional performance. Fourteen healthy male soccer players received each of the stretching conditions (regular stretching only (Regular), regular stretching with soleus stretching (Soleus) and no stretching (Control)) randomly on different training days, with two-day separation. The ankle flexibility, standing heel-lift balance and speed performances were assessed following each stretching intervention. The active dynamic stretches were performed for 30 s with three repetitions on each of the three (Regular) and four (Soleus) muscles. One-way ANOVA with repeated measures (or the Friedman non-parametric test) was performed to determine any significant effect with alpha = 0.05. Our findings revealed that both the Regular and Soleus stretching groups showed an increased active range of ankle motion compared to the no-stretching control (Ps < 0.05). In the heel raise balance test, both stretching groups experienced a significant increase in maximum plantarflexion strength as well as resultant anterior–posterior and medial–lateral CoP excursions compared to the no-stretching control (Ps < 0.05). In the sprinting tasks, both the Soleus and Regular stretching groups induced faster linear and curved running times (Ps < 0.05). When comparing the two stretching groups, Soleus stretching led to better ankle flexibility, maximum plantarflexion strength and curved running time (Ps < 0.05). Thus, added stretches on the soleus muscles can provide further benefits to speed performances in soccer.

The restoration of the rose (15th century) of the Sainte-Chapelle in Paris, France, o ff ered a unique opportunity to investigate the color and chemical composition of these emblematic medieval French stained glasses with non-destructive analyses. The obtained results are aimed at complementing the knowledge from art historians and thus together trying to compensate for the total absence of archives on the construction of the rose. Comparison with the glasses of the nave (13th century) reveals an important evolution of the aesthetics based on new types of glasses: new colors and extensive use of flashed glass. The systematic study of the chemical composition of both sides of each glass piece revealed that about half of the studied glasses were flashed. For non-flashed glasses, this comparison allowed evaluating the influence of glass surface weathering, although very moderate, on the composition variability. In light of the variability criteria, the multivariate analysis of the chemical composition allowed inferring that most glasses originate from the same production glasshouse.
Food Science of Animal Resources

Extracellular vesicles (EVs) are nanosized vesicles secreted from cells into the extracellular environment and are composed of a lipid bilayer that contains cargos with biological activity, such as lipids, proteins, mRNAs, and noncoding microRNAs (miRNAs). Due to their biological activity and their role in cell-to-cell communication, interest in EVs is rapidly increasing. Bovine milk is a food consumed by people of all ages around the world that contains not only a significant amount of nutrients but also EVs. Milk-derived EVs also exhibit biological activity similar to other source-derived EVs, and studies on bovine milk EVs have been conducted in various research fields regarding sufficient milk production. In particular, not only are the effects of milk EVs themselves being studied, but the possibility of using them as drug carriers or biomarkers is also being studied. In this review, the characteristics and cargo of milk EVs are summarized, as well as their uptake and stability, efficacy and biological effects as carriers, and future research directions are presented.
Old But Not Out: Social Media Use and Older Adults' Life Satisfaction

Social media has the potential to have a positive influence on older adults' quality of life. This study explores how older adults use social media and the implications of the use on their life satisfaction. A sequential mixed-method approach is used. First, focus group interviews were conducted with older adults in Thailand, and a two-step sorting procedure is employed to develop comprehensive measures of social media use activity and their life domain affiliation. Next, a field survey is used to evaluate the influence of satisfaction from social media use on domain life satisfaction and overall life satisfaction. The findings suggest that older adults integrate social media into activities in several life domains, including family, friend, community, health, consumer, education, self, leisure, and social. Satisfaction from social media use activities positively associates with domain life satisfaction in all those life domains. The comprehensive measures of social media activities enable us to extensively theorize social media use and illustrate that it has a different meaning for older adults compared with young adults.
Economic Policy Uncertainty and Manufacturing Value-added Exports

This study explores the effects of increased economic policy uncertainty (EPU) in both importing and exporting countries on manufacturing value-added exports. The results show that increased EPU of both importing and exporting countries would result in decreases in manufacturing value-added trade flows, and the negative effect of exporters' EPU is larger than that of importers' EPU. Our results also provide evidence on the influence channels: increased EPU of exporting countries affects manufacturing value-added trade flows primarily through the cost to export, while increased EPU of importing countries primarily through market demand. This conclusion is robust to a series of robustness checks.
Teenagers Language Politeness Strategy on Social Media WhatsApp Based on Level of Education

Language politeness in social media is still often ignored. The article aims to describe teenagers' politeness strategies in social media conversations, especially in the WhatsApp group of junior high schools, senior high schools, and colleges. The research was quantitative and qualitative descriptive, and the population was complete sentences in WhatsApp group conversations. The period of recording the conversation with each group is during September 2021. The data collection technique is by exporting the conversation data to Ms. Words. The data were arranged based on the entry date, then coded using Brown & Levinson's politeness theory. The interpretation of the data classification results used the approach of Makassar's cultural perspective. The findings showed that in social media WhatsApp, the teenagers talked more frequently used three kinds of politeness strategies. 1) Bald on record involving questions, commands, and requests. Teenagers use this strategy from three-level of education. 2) Positive strategies involve jokes, identity, and paying attention. The college and high schools teenagers use jokes and identity. However, paying attention's strategy is just used by college teenagers. 3) Negative strategies include apologies, be-thankful, and questions. College and high schools teenagers use the apology and thank strategies. Nevertheless, teenagers from the high school level only used negative politeness in asking questions. In conclusion, the level of education of teenagers determines the use of politeness strategy in social media. The implication is that teachers and stakeholders pay more attention to students' language politeness building, especially in speaking politely to others, so their interaction is harmonious with their communities.
In silico assessment of aquatic bioaccumulation: advances from chemometrics and QSAR modelling

This doctoral dissertation addresses some of the current open problems in the prediction of aquatic bioaccumulation of organic chemicals, by exploiting Quantitative Structure-Activity Relationship (QSAR) and chemometric techniques. It aims to advance the mechanistic knowledge about the bioaccumulation processes and to overcome some of the existing modelling gaps. Bioconcentration and dietary bioaccumulation are addressed separately, using fish as the target organism. The bioconcentration is considered the main bioaccumulation route and, therefore, the Bioconcentration Factor (BCF) has been widely modelled. However, in this work, the comparison of nine wellestablished models for BCF showed that, in most of the cases, only lipid-driven bioconcentration is well predicted and other influential processes, such as storage within non-lipid tissues or metabolism, are neglected. This set the basis for the development of a classification scheme to identify compounds that (1) are well predicted by their lipophilicity, (2) have additional storage sites (e.g. proteins) and an increased BCF, or (3) are metabolized/eliminated, with a reduced bioconcentration. The classification scheme allowed to gather knowledge about the mechanisms of bioconcentration, and to develop an expert system to choose the most appropriate modelling tool according to the predicted bioconcentration mechanism. The final expert system led to an increased accuracy than its sub-models. The second target was the dietary bioaccumulation, expressed through the laboratory-based Biomagnification Factor (BMF), which is usually not considered for the bioaccumulation assessment. The comparison between BMF and BCF revealed that, for some chemical classes, the
The Development of Teacher Burnout and the Effects of Resource Factors: A Latent Transition Perspective

To better understand burnout and its development, researchers have shown an increasing interest in recent years in identifying different profiles of burnout and its development process. However, there have been few longitudinal studies on the profile and development of teacher burnout. This study used a person-centred approach to explore the profiles of teacher burnout, transition probabilities and the associations between these aspects and resource factors. Data were collected from 3743 primary school teachers in a two-wave longitudinal test over three years. The results showed that teacher burnout exhibited six relatively stable profiles across the whole study population and that the transition of individual profiles over time followed a certain probability. Psychological capital and professional identity were important resource factors in reducing the occurrence of teacher burnout and increasing transition probability toward burnout symptom alleviation over time, while positive coping played an important role in reducing the occurrence of teacher ineffectiveness. Therefore, the results indicated that the overall teacher burnout profile was stable, a discovery which has important implications for conducting group interventions to benefit more teachers, while the individual burnout profile exhibited a latent transition probability over time. Interventions employing different resource factors can be adopted to alleviate the symptoms of different burnout profiles.
Risk for youth anxiety during the COVID‐19 pandemic: The interactive impact of financial stress and prepandemic electrocortical reactivity to negative self‐referential stimuli

Abstract Despite evidence that stress exposure increases risk for internalizing symptoms in youth, it remains unclear which youth are most vulnerable. This study examined whether youth's prepandemic late positive potential (LPP), an electrocortical marker of sustained attention to affective stimuli, exacerbated the impact of stress on prospective increases in depression and anxiety symptoms from before to during the COVID‐19 pandemic. Participants were 29 youth (ages 9–16, 82.8% girls) who completed depression and anxiety symptom measures and an affective words task to assess LPP to positive and negative self‐referential stimuli prepandemic onset. Postpandemic onset, approximately 16.03 months (SD = 8.86) after their baseline assessments, youth again completed symptom measures as well as the UCLA Life Stress Interview to assess ongoing social and financial chronic stress. Results indicated a significant interaction between youth LPP to negative words and financial stress. Greater exposure to financial stress during the pandemic predicted greater anxiety symptom increases specifically for youth who demonstrated enhanced prepandemic LPP to negative words. Results were specific to the prediction of anxiety, but not depression, symptoms. If replicated in larger studies, findings highlight enhanced LPP to negative stimuli as a promising target for intervention for youth exposed to greater financial stress.
Exercise for Trismus Prevention in Patients with Head and Neck Cancer: A Network Meta-Analysis of Randomized Controlled Trials

A common side effect of managing head and neck cancer is trismus, which devastates patients’ quality of life. The purpose of this study was to investigate prophylactic exercise interventions for preventing trismus and difficulty in mouth opening in head and neck cancer. Five databases were searched for randomized controlled trials. Network meta-analysis was performed with risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). This study finally included 11 randomized controlled trials (n = 805). Trismus risk in patients who received exercise with phone call follow up (E + P) was significantly lower than those received usual care (RR = 0.42; 95% CI: 0.29 to 0.61) and exercise alone (RR = 0.33; 95% CI: 0.18 to 6.22). Mouth opening in usual care was significantly lower than in the tri-integrated strategy group (MD = 15.22; 95% CI: 8.88 to 21.56). Exercise is recommended for preserving mouth opening distance in patients with head and neck cancer. Tri-integrated strategies could be an effective method for preventing trismus.

Visual function assessment of posterior-chamber phakic implantable collamer lenses with a central port

Background To investigate the short-term visual function of the V4c implantable collamer lens (ICL) for myopia using a Binoptometer 4P. Methods Eighty eyes from 40 patients (age, 28.75±6.57 years) who underwent ICL V4c implantation at Shenzhen Eye Hospital from August 2020 to June 2021 were enrolled. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), subjective manifest refraction, intraocular pressure (IOP), and corneal endothelial cell density (ECD) were evaluated 1 month after surgery. Corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA), contrast sensitivity (CS), near stereoacuity (NSA), twilight vision, and glare sensitivity were measured using a Binoptometer 4P. Results The average logMAR (logarithmic minimum angle of resolution) UCVA postoperative was 0.07±0.13, which was significantly better than the preoperative BCVA (P=0.028). At 1 month postoperatively, the mean safety and efficacy indexes were 1.14±0.24 and 0.98±0.16, respectively. The mean spherical equivalent (SE) of all eyes was −8.98±3.20 D preoperatively, and −0.16±0.48 D postoperatively. None of the patients lost one or more lines of BCVA, 62.1% remained unchanged, 10.6% gained one line, and 27.3% gained two or more lines. CDVA, CNVA, CS, and NSA of both eyes were measured using a Binoptometer 4P, which were significantly better than the preoperative values. In addition, some patients had subjective symptoms in the early postoperative period, such as halo, glare, etc. Conclusions ICL V4c implantation is a safe, effective, and predictable solution for myopia. We found that the short-term visual function of patients was improved significantly. The Binoptometer 4P is an effective and convenient visual testing device for assessing postoperative visual function after ICL V4c implantation.
Correlation between leukocyte phenotypes and prognosis of amyotrophic lateral sclerosis

The prognostic role of immune cells in amyotrophic lateral sclerosis (ALS) remains undetermined. Therefore, we conducted a longitudinal cohort study including 288 ALS patients with up to 5-year follow-up during 2015–2020 recruited at the only tertiary referral center for ALS in Stockholm, Sweden, and measured the levels of differential leukocytes and lymphocyte subpopulations. The primary outcome was risk of death after diagnosis of ALS and the secondary outcomes included functional status and disease progression rate. Cox model was used to evaluate the associations between leukocytes and risk of death. Generalized estimating equation model was used to assess the correlation between leukocytes and functional status and disease progression rate. We found that leukocytes, neutrophils, and monocytes increased gradually over time since diagnosis and were negatively correlated with functional status, but not associated with risk of death or disease progression rate. For lymphocyte subpopulations, NK cells (HR= 0.61, 95% CI = [0.42–0.88] per SD increase) and Th2-diffrentiated CD4+ central memory T cells (HR= 0.64, 95% CI = [0.48–0.85] per SD increase) were negatively associated with risk of death, while CD4+ effector memory cells re-expressing CD45RA (EMRA) T cells (HR= 1.39, 95% CI = [1.01–1.92] per SD increase) and CD8+ T cells (HR= 1.38, 95% CI = [1.03–1.86] per SD increase) were positively associated with risk of death. None of the lymphocyte subpopulations was correlated with functional status or disease progression rate. Our findings suggest a dual role of immune cells in ALS prognosis, where neutrophils and monocytes primarily reflect functional status whereas NK cells and different T lymphocyte populations act as prognostic markers for survival.
Biosynthesis and Characterization of Silver Nanoparticles Produced by Phormidium ambiguum and Desertifilum tharense Cyanobacteria

The world faces a challenge with the pervasion of multidrug-resistant bacteria that encourages scientists to develop and discover alternative, ecofriendly, and easy-to-produce new antibacterial agents. Our work is part of the greater effort of scientists around the world to achieve this goal by the biological synthesis of silver nanoparticles using cyanobacterial extracellular and intracellular components as nonchemical reducing agents. Two Egyptian cyanobacteria were isolated and identified according to 16S rRNA gene sequencing as Phormidium ambiguum and a novel species Desertifilum tharense. The sequences were deposited with accession numbers MW762709 and MW762710 for Desertifilum tharense and Phormidium ambiguum, respectively, in the GenBank. The results of UV-Vis analysis showed promising extracellular Ag-NPs synthesis by Desertifilum tharense and Phormidium ambiguum under light conditions. Therefore, these Ag-NPs were characterized and evaluated for antibacterial and antioxidant activity. TEM and SEM analyses revealed the spherical crystals with face-centered cubic structures and size range of 6.24–11.4 nm and 6.46–12.2 nm for Ag-NPs of Desertifilum tharense and Phormidium ambiguum, respectively. XRD and EDX results confirmed the successful synthesis of Ag-NPs in their oxide form or chloride form. The FTIR spectrum data confirmed the presence of hydroxyl and amide groups. Desertifilum tharense Ag-NPs displayed the largest inhibition zone that ranged from 9 mm against Micrococcus luteus ATCC 10240 to 25 mm against methicillin-resistant Staphylococcus aureus (MRSA) ATCC 43300. For Phormidium ambiguum Ag-NPs, the inhibition zone diameter was in the range of 9 mm to 18 mm. The biosynthesized Ag-NPs significantly inhibited the growth of medically important resistance-pathogenic Gram-positive and Gram-negative bacteria. The Ag-NPs of Phormidium ambiguum exhibited the highest scavenging activity of 48.7% when compared with that of Desertifilum tharense, which displayed 43.753%.
Annual dynamics of eukaryotic and bacterial communities revealed by 18S and 16S rRNA metabarcoding in the coastal ecosystem of Sagami Bay, Japan

Sagami Bay, Japan is influenced by both the warm Kuroshio Current and the cold Oyashio Current and rich nutrients are supplied from multiple river sources and the deep-sea, forming a dynamic ecosystem. The aim of the present study was to investigate eukaryotic and bacterial communities in the coastal waters of Sagami Bay, using 16S rRNA and 18S rRNA sequencing and to assess the seasonal and vertical dynamics in relation to physicochemical and biological conditions. Eukaryotic and bacterial communities showed synchronous seasonal and vertical changes along with environmental variability. Diversity of plankton community suspended in the surface was lower than those at the subsurface layers in both the eukaryotes and bacteria communities; however, community diversity showed different characteristics in the subsurface where the eukaryotic community at the deeper layer (100 m) was as low as the surface and highest in intermediate depth layers (10–50 m), while that of bacterial community was highest in the deeper layer (100 m). The annual variability of the coastal microbial communities was driven, not only by the seasonal changes of abiotic and biotic factors and short-term rapid changes by river water inflow and phytoplankton blooms, but also largely influenced by deep-seawater upwellings due to the unique seafloor topography.
