Published: May 2023

The main problem of the research was to determine the relationship between goal orientation, satisfaction, self-esteem, and situational motivation among young karate athletes from Republic of North Macedonia. The research was carried out on a sample of 100 respondents who are engaged in karate sport between the ages of 11 and 14 from Republic of North Macedonia. The sample is divided into two subsamples according to gender, namely 54 male respondents and 45 female respondents. The sample was drawn from several karate clubs in Republic of North Macedonia. In order to realize the goals of the research, several scales were applied to assess goal orientation, satisfaction, self-esteem and situational motivation. The obtained data were processed with appropriate parametric statistical methods. Based on the obtained results, it can be concluded that a larger number of respondents (young karate athletes) from our sample are more focused on developing and improving their competence, and less on achieving results and relying on their abilities. Interrelationships among the four subscales assessing the level of self-determination to be physically active, as expected the more proximal along the continuum are more positively correlated with task orientation than those more distal along the continuum. The research results confirm that task orientation is more positively related to more self-determined types of situational motivation (the internal motivational regulator -intrinsic motivation and the identification motivational regulator -identified regulation) and negatively related to less self-determined types of situational motivation (external motivational regulator- external regulation and guilt regulator - introjected regulation). Based on all that has been stated, it can be concluded that among young karate athletes aged 11 to 14, internal motives (i. e. fun, personal challenge, etc.) or so-called essential motives for playing sports should be promoted.

The influence of organized physical exercise on the time spent in MVPA of elementary school students
Authors: Bubnjević Ksenija , Romanov Romana , Grujičić Dragan
Published: May 2023

The World Health Organization recommends daily physical activity for at least 60 minutes for children, while for adults this recommendation amounts to at least 30 minutes a day. As part of daily physical activity, it is recommended to exercise at a moderate to high intensity for at least 10 minutes. Today, we are increasingly faced with the problem of sedentariness in both adults and children. It is considered that a school is a place where children could be expected to be more physically active because they spend a lot of time there. The subject of this research concerns the time spent in moderate to high-intensity physical activity (MVPA) during one day. A systematic review of two electronic databases (PubMed and Mlibrary) identified a small number of studies that analyzed MVPA between boys and girls. In the studies, organized physical exercise is cited as a way to make children more interested in exercise than usual. The research results of three selected studies indicate that students are not sufficiently physically active and that there are no significant differences in MVPA values between boys and girls (8 to 14 years of age). On the basis of highly qualified scientific studies, including only studies that measured MVPA with an accelerometer, it is observed that boys achieved higher values and are therefore somewhat more physically active compared to girls.

Published: May 2023

The aim of the research is to determine the relations and influences of motor abilities on the performance of some elements of the basketball techniques in the 7th and 8th graders. The study included 85 respondents, students of 7th and 8th grade of elementary school “Prekounje” from Bihać. The motor status assessment system was represented by the 12 variables (three variables each to assess coordination, explosive strength, flexibility and speed), while 4 situational-motoric tests were used to assess the success of the performance of the elements of basketball techniques: 1. Throwing the ball with both hands against the wall and catching it for 30 seconds (BHLR30), 2. Dribbling the ball with the hand in a slalom (VLRS), 3. Throwing the ball into the basket for 30 seconds (ULK30), 4. Lay-ups for 30 seconds (PNK30). Basic central and dispersion parameters were calculated for all variables which confirmed the normality of the distribution, and the relations between spaces were determined by using the canonical correlation analysis. Values ​​obtained by canonical correlation analysis indicate very high correlation between basic motor abilities and basketball skills.

Published: May 2023

Obesity incidence is increasing worldwide with the urgent need to identify new therapeutics. Sex differences in immune cell activation drive obesity-mediated pathologies where males are more susceptible to obesity comorbidities and exacerbated inflammation. Here, we demonstrate that the macrophage-secreted protein RELMα critically protects females against high-fat diet (HFD)-induced obesity. Compared to male mice, serum RELMα levels were higher in both control and HFD-fed females and correlated with frequency of adipose macrophages and eosinophils. RELMα-deficient females gained more weight and had proinflammatory macrophage accumulation and eosinophil loss in the adipose stromal vascular fraction (SVF), while RELMα treatment or eosinophil transfer rescued this phenotype. Single-cell RNA-sequencing of the adipose SVF was performed and identified sex and RELMα-dependent changes. Genes involved in oxygen sensing and iron homeostasis, including hemoglobin and lncRNA Gm47283/Gm21887, correlated with increased obesity, while eosinophil chemotaxis and response to amyloid-beta were protective. Monocyte-to-macrophage transition was also dysregulated in RELMα-deficient animals. Collectively, these studies implicate a RELMα–macrophage–eosinophil axis in sex-specific protection against obesity and uncover new therapeutic targets for obesity.
CPJSdraw: analysis and visualization of junction sites of chloroplast genomes
Authors: Li Huie , Guo Qiqiang , Xu Lei , Gao Haidong , Liu Lei , Zhou Xiangyang
Published: May 2023

Background

Chloroplast genomes are usually circular molecules, and most of them are tetrad structures with two inverted repeat (IR) regions, a large single-copy region, and a small single-copy region. IR contraction and expansion are among the genetic diversities during the evolution of plant chloroplast genomes. The only previously released tool for the visualization of junction sites of the regions does not consider the diversity of the starting point of genomes, which leads to incorrect results or even no results for the examination of IR contraction and expansion.

Results

In this work, a new tool named CPJSdraw was developed for visualizing the junction sites of chloroplast genomes. CPJSdraw can format the starting point of the irregular linearized genome, correct the junction sites of IR and single-copy regions, display the tetrad structure, visualize the junction sites of any number (≥1) of chloroplast genomes, show the transcription direction of genes adjacent to junction sites, and indicate the IR expansion or contraction of chloroplast genomes.

Conclusions

CPJSdraw is a software that is universal and reliable in analysis and visualization of IR expansion or contraction of chloroplast genomes. CPJSdraw has more accurate analysis and more complete functions when compared with previously released tool. CPJSdraw as a perl package and tested data are available at http://dx.doi.org/10.5281/zenodo.7669480 for English users. In addition, an online version with a Chinese interface is available at http://cloud.genepioneer.com:9929/#/tool/alltool/detail/335.
La inaplicación del Derecho Convencional creado por la Corte Interamericana de Derechos Humanos en relación al derecho a la vida del concebido
Authors: Castillo Córdova Luis
Published: May 2023

De la mano del derecho fundamental a la vida del concebido se muestra la an-tinomia que surge entre dos normas constitucionales, una de origen nacional creada por elTribunal Constitucional peruano y otra de origen convencional creada por la Corte IDH, queconforman el contenido constitucional del mencionado derecho fundamental. Planteada laantinomia se propone solucionarla desde las bases dogmáticas propias del Estado constitucio-nal de derecho, que proscriben que la solución exclusivamente se sostenga en razones de auto-ridad. Así, se resuelve no desde una relación de supremacía del derecho convencional sobre elnacional, sino desde una efectiva relación de complementariedad, para el logro efectivo de laplena realización de las personas a través de la plena vigencia de los derechos humanos. Unatal solución representa, a la vez, límites razonables al control de convencionalidad en manos dela Corte IDH y promueve un efectivo diálogo entre esta y las cortes nacionales de justicia.

Altruismo y solidaridad en el derecho de contratos
Authors: Pereira Fredes Esteban
Published: May 2023

De manera tradicional, se considera que el derecho de contratos está uniformemente fundamentado en el individualismo. Este sustento normativo afirma la diferencia entre los intereses propios y ajenos, abogando por el predominio del autointerés. Sin embargo, los recientes eventos que han incidido en la contratación invitan a evaluar críticamente si solo hay un fundamento normativo común. Al respecto, la solidaridad y el altruismo desafían los postulados del individualismo y pueden esgrimirse como candidatos para la fundamentación del derecho contractual. Este trabajo explora tal posibilidad y busca posicionar la solidaridad y el altruismo en ese ámbito. Finalmente, se muestra en qué sentido el altruismo tiene mayor pertinencia que la solidaridad para fundamentar el derecho de contratos y hacer frente al prisma individualista.

En el presente trabajo se analiza la labor jurisprudencial en la determinación delas condiciones de validez para el ejercicio de la facultad unilateral de movilidad geográficaen el ordenamiento jurídico peruano. A pesarde la inexistencia de regulación específicasobre la modificación de las condiciones sustanciales de trabajo; y, a partir de la regulacióngenérica de los límites del poder de dirección, delius variandiy de las disposiciones sobreactos de hostilidad del empleador, tanto la Corte Suprema como el Tribunal Constitucional,han establecido que la decisión de movilidad geográfica, en tanto afecta a una de lascondiciones sustanciales del contrato de trabajo, requiere la prueba empresarial de la causajustificativa razonable relacionada con las necesidades de la empresa y la prueba de lasrazones de la elección del concreto trabajador. Asimismo, que la decisión empresarial nocause perjuicios al trabajador, entendiendo por tales a cualquier daño patrimonial oextrapatrimonial que afecte irrazonablemente los derechos e intereses del trabajador o losde su núcleo familiar. Tales exigencias evidencian una labor judicial enmarcada dentro delmandato constitucional de dotar de protección al trabajador y de garantizarla efectivavigencia de los derechos fundamentales en el ámbito laboral. Finalmente, tales exigenciascarecerían de sentido si en el ámbito del proceso laboral no se establecieran mecanismosque faciliten, como de hecho ha ocurrido, la probanza del acto abusivo cometido por elempleador. Se analizará también los criterios judiciales sobre facilitación probatoria–através de la prueba de indicios–que coadyuva a hacer efectivo el principio protector en elámbito del proceso de trabajo.

O Decreto 9.094/2017, que institui a Carta de Serviços ao Usuário, busca atender as demandas de informação e transparência ao usuário do serviço, o que inclui os usuários das universidades federais de ensino superior (UFES). Assim, o presente estudo buscou avaliar como este dispositivo legal tem sido cumprido pelas 68 UFES, ou seja, se a Carta tem sido disponibilizada aos usuários. Para tanto, foi realizada uma pesquisa exploratória e descritiva destas UFES e em especial da Universidade Federal Rural de Pernambuco, utilizando as estratégias de levantamento e estudo de caso. Como resultado, constatou-se que a maioria das universidades pesquisadas possuem a Carta publicada no site institucional, porém, com objetivo único de atender ao requisito básico do decreto e não de auxiliar o acesso ao usuário. Os resultados demonstraram que cerca de 94% das UFES disponibilizam a Carta de Serviços ao Usuário em seus sítios eletrônico. A UFRPE faz parte dessas instituições e vem aprimorando sua política de transparência com a adoção da carta de serviço ao cidadão, mesmo que tardiamente.

Piper betel - Not Just a Mouth Freshener But Also a Miraculous Herb for Healing: A Review
Authors: Panda Nivedita , Panda Arpita
Published: May 2023

Piper betle L., often known as betel vine, is a member of the Piperaceae family and is a significant cash crop for both economic and therapeutic purposes. The betle vine is most likely from Malaysia, while it is also grown in India, Sri Lanka, Bangladesh, Myanmar, and Nepal. It is grown in the districts of Balasore, Jagatsinghpur, Puri, Khordha, and Ganjam along Odisha's coast. With tremendous potential for creating jobs and improving the socioeconomic situations of rural people in India and other Asian nations, betel vine has enormous economic, medical, and nutraceutical value. However, there are still a number of significant elements of these plants that have not received enough consideration. Over a million people in Odisha use paan, yet most are not aware of its superior nutritional value. The most common chewing combinations for Piper betel include sliced areca nut, slaked lime, coriander, aniseed, clove, cardamom, sweetener, and coconut scrapings. Along with its traditional uses, Piper betel's therapeutic characteristics have the power to treat a variety of illnesses and lessen mouth cancer, which is actually brought on by sliced areca nuts and slaked lime rather than betel leaves. Betel leaves are a great source of vitamins, minerals, phytochemicals, antioxidants, protein, lipids, fibre, calcium, iron, and many other nutrients. Many research studies on Piper betle have reported that it contains important chemical constituents such as chavibetol, chavibetol acetate, caryophyllene, allylpyrocatechol diacetate, campene, chavibetol methyl ether, eugenol, a-Pinene, f-Pinene, u-Limonene, saprobe, 1-8-cineol, allylpyrocatechol monoacetate etc. Betel leaf is one of nature's best medicines and is thought to be superior to medications. Additionally, the leaves retain an essential oil (EO) with a high eugenol content (1-3%), which is a popular ingredient in medicines, stimulants, antiseptics, tonics, and other ayurvedic formulations. The demand for its goods, such as herbal medications, treatments, and natural herbal formulations, has grown recently. Additionally, Piper betel aids in the treatment of a wide range of illnesses, including rheumatism, diabetes, hypertension, halitosis, boils and abscesses, obesity, voice issues, conjunctivitis, constipation, headache, itches, mastitis, mastoiditis, leucorrhoea, otorrhoea, ringworm, gum swelling, and many others. The botanical description, geographic distribution, economic worth, cultivation, and ethnobotanical use of P. betle are all succinctly summarised in the current paper. According to the research, P. betle is a naturally occurring, safe, and orally active drug with significant therapeutic potential for treating a range of human medical disorders. To better understand its underlying molecular mechanisms of action, clinical features, structure-activity connections, bioavailability, and synergistic interactions with other medications, more research is still required.

Published: May 2023

Human papilloma Virus (HPV) is the primary infection that causes Cervical cancer. Due to the high cost of treatment for cervical cancer, protection against HPV and Cervical cancer infection may be preferable in a scarce resource settings. In this paper, a deterministic model that incorporates protection against the infection was developed and analysed. The endemic state is shown to exist provided that the reproduction number is greater than unity. Furthermore, by the use of Routh-Hurwitz criterion and suitable Lyapunov functions, Endemic Equilibrium (EE) is shown to exist provided that the reproduction number is greater than unity. By use of a suitable Lyapunov function, the endemic state was shown to be globally asymptotically stable. The effectiveness of protection is achieved if well done hence, an increase in protection leads to low disease prevalence in a population.

Published: May 2023

The management of water resources in both irrigated and rain-fed agriculture is becoming an increasingly complex worldwide due to anticipated water scarcity, and compounded by the challenges of global warming and climate change. Climate-smart water technologies viz. Drip irrigation, Central pivot irrigation, Hydrogel and SWAT method need to be judiciously applied to overcome these challenges. Agriculture is a critical sector in India and other developing countries, providing substantial employment opportunities to rural populations and supporting efforts to achieve food and nutritional security. This paper addresses the challenge of increasing food production and improving rural livelihoods while safeguarding critical water resources for sustainable use, particularly in drought-prone regions, through adaptive measures for effective water management. An integrated approach is necessary for agricultural water management through the adoption of innovative technologies such as water harvesting, micro-irrigation, and resource conservation farming to increase water-use efficiency in agriculture and other critical services to humans and animals. The study aims to enhance understanding of the potential implications of climate change and adaptation options for agricultural water management, thereby enabling them to take up adaptation challenges and develop measures to reduce the farming sector's vulnerability to climate change.

Published: May 2023

Importance

National Hockey League (NHL) players are exposed to frequent head trauma. The long-term consequences of repetitive brain injury, especially for players who frequently engage in fighting, remains unknown.

Objective

To investigate the mortality rates and causes of death among NHL enforcers with more career fights and penalty minutes as compared with matched controls.

Design, Setting, and Participants

This matched cohort study examined 6039 NHL players who participated in at least 1 game in the seasons between October 11, 1967, and April 29, 2022, using official NHL data. Cohorts designated as enforcer-fighter (E-F) and enforcer-penalties (E-P) were selected. The E-F cohort consisted of players who participated in 50 or more career fights (n = 331). The E-P cohort included players with 3 or more penalty minutes per game (n = 183). Control-matched NHL players were identified for each E-F player (control-fighter [C-F]) (n = 331) and each E-P player (control-penalties [C-P]) (n = 183).

Exposures

Fighting and penalty minutes were both used as proxies for head trauma exposure. Players with significantly increased exposure to fighting and penalties (E-F and E-P cohorts) were compared with NHL players with less frequent exposure to head trauma (C-F and C-P cohorts).

Main Outcomes and Measures

Mortality rates and age at death of the enforcer and control cohorts, and their causes of death using data obtained from publicly available sources such as online and national news sources, including NHL.com.

Results

Among the 6039 NHL players identified (mean [SD] age, 47.1 [15.2] years), the mean (SD) number of fights was 9.7 (24.5). The mortality rates of E-F and C-F players (13 [3.9%] vs 14 [4.2%], respectively; P = .84) or E-P and C-P players (13 [7.1.%] vs 10 [5.5%]; P = .34) were not significantly different. The mean (SD) age at death was 10 years younger for E-F players (47.5 [13.8] years) and E-P players (45.2 [10.5] years) compared with C-F players (57.5 [7.1] years) and C-P players (55.2 [8.4] years). There was a difference in causes of death between the control and enforcer players (2 neurodegenerative disorders, 2 drug overdoses, 3 suicides, and 4 vehicular crashes among enforcers vs 1 motor vehicle crash among controls; P = .03), with enforcers dying at higher rates of overdose (2 of 21 [9.5%] vs 0 of 24) and suicide (3 of 21 [14.3%] vs 0 of 24) (P = .02).

Conclusions and Relevance

The findings of this matched cohort study indicate that there is no difference in overall mortality rates between NHL enforcers and controls. However, being an enforcer was associated with dying approximately 10 years earlier and more frequently of suicide and drug overdose.

Published: May 2023

Stereotactic radiotherapy (SRT) methods have become common for the treatment of small tumors in various parts of the body. Small field dosimetry has a unique set of challenges when it comes to the pre‐treatment validation of a radiotherapy plan that involves film dosimetry or high‐resolution detectors. Comparison of commercial quality assurance (QA) devices to the film dosimetry method for pre‐treatment evaluation of stereotactic radiosurgery (SRS), fractionated SRT, and stereotactic body radiation therapy treatment plans have been evaluated in this study. Forty stereotactic QA plans were measured using EBT‐XD film, IBA Matrixx Resolution, SNC ArcCHECK, Varian aS1200 EPID, SNC SRS MapCHECK, and IBA myQA SRS. The results of the commercial devices are compared to the EBT‐XD film dosimetry results for each gamma criteria. Treatment plan characteristics such as modulation factor and target volume were investigated for correlation with the passing rates. It was found that all detectors have greater than 95% passing rates at 3%/3 mm. Passing rates decrease rapidly for ArcCHECK and the Matrixx as criteria became more strict. In contrast, EBT‐XD film, SNC SRS MapCHECK, and IBA myQA SRS passing rates do not decline as rapidly when compared to Matrix Resolution, ArcCHECK, and the EPID. EBT‐XD film, SNC SRS MapCHECK, and IBA myQA SRS maintain greater than 90% passing rate at 2%/1 mm and greater than 80% at 1%/1 mm. Additionally, the ability of these devices to detect changes in dose distribution due to MLC positioning errors was investigated. Ten VMAT SBRT/SRS treatment plans were created with 6 MV FFF or 10 MV FFF beam energies using Eclipse 15.6. A MATLAB script was used to create two MLC positioning error scenarios from the original treatment plan. It was found that errors in MLC positioning were most reliably detected at 2%/1 mm for high‐resolution detectors and that lower‐resolution detectors did not consistently detect MLC positioning errors.

In recent years, the development of high‐speed railways in China has been rapid. High‐speed railway bridges play an essential role whenever the railway intersects with existing facilities in three dimensions. With the increasing speed of high‐speed railways and increasingly complex geographical locations, the span of bridges is constantly increasing. Based on their advantages, steel structures in large‐span bridges are beginning to replace traditional concrete structures. Taking the steel cover beam technology applied in the Fuqiangbao Tremendous Bridge as a starting point, this paper uses Rhino parameterized modeling and Abaqus software to conduct finite element analysis on the stress of steel cover beams. It compares and analyzes stress under different conditions. The results show that the steel cover beam's most unfavorable and unstable position in this paper is at the support on the stress side. This provides a reference for monitoring the steel cover beam after its application in the Fuqiangbao Tremendous Bridge and technical accumulation for the application of steel cover beam technology.

Lignin is one of the most common naturally occurring macromolecules. It is associated with cellulose and hemicelluloses in terrestrial plants, providing mechanical stiffness and contributing to moisture control and defense toward insects and fungi. Lignin is typically a polymer of three different cinnamyl alcohols, para‐coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol, which varies with the plant species. Solubilized lignin from the kraft pulping process is mainly concentrated and burned as part of the liquor recovery cycle in the kraft pulping. Given its aromatic nature, other uses of lignin include the development of platform chemicals, polymers, and fuels. This work uses lignin to develop carbon fibers to act as supercapacitors. Lignin microfibers were produced using an electrospinning process, carbonized under an inert atmosphere, and activated to increase surface area and improve capacitance. The activation process is shown to improve the specific capacitance of the material. In addition to activation, nanocrystals were grown on the surface of the carbon microfibers as these nanocrystals have been shown to improve the specific capacitance. When both surface modifications are performed to the lignin‐based carbon fiber, it improves the specific capacitance retention regarding scan rate increase during cyclic voltammetry. The specific capacitance for the carbon fiber, activated carbon fiber, Ni(OH)2 carbon fiber, and Ni(OH)2 activated carbon fiber at 10 mV/s are 189, 206, 10, and 103 F/g.

Published: May 2023

Two responsive PEI hydrogels (P1.5E and P2E) were synthesized through a click reaction using linear PEI polymers with different cross‐linker contents (ethylene glycol diglycidyl ether—EGDE) and avoiding organic solvents. Through 13C HRMAS NMR and DSC studies the presence of residual epoxy groups and different protonation states of the linear PEI segments in the hydrogel were detected. The swelling and rheological behavior was dependent on the cross‐linking degree. The hydrogel with the lower cross‐linking degree (P1.5E) presented higher swelling values, but it was less resistant to the deformation. Besides, the swelling capacity and the resistance to deformation were found to be dependent on the interchain repulsions and charge of the amine groups, which endowed the hydrogels with stimuli‐responsive behavior to pH or ionic strength changes. For both hydrogels, the swelling capacity and rheological properties were inversely proportional and directly proportional to the pH increase, respectively. Both materials presented adsorption capacity for the azo dye methyl orange (MO) and Cu2+ ions. The interaction of the materials with the pollutants was also dependent on the cross‐linking degree, being P1.5E the one that presented higher sorption capacities. Furthermore, the hydrogels did not release toxic molecules, as assessed by lettuce seeds germination experiments.
From here to I.A.P.T? (improving access to psychological therapies), preview for a new deal for dynamic psychotherapies: The psychoanalyst as street‐level bureaucrat
Authors: Clarke Jeremy C.
Published: May 2023

This paper offers a preview of a forthcoming article on the world's first, universal free‐to‐access, evidence‐based talking therapies programme to treat depression: Improving Access to Psychological Therapies. It was pioneered not in the USA, but the UK, in 2007. At one time it could have been led by psychoanalysts, but it wasn't. It was a New Deal, in fact, for CBT. But did this New Deal in 2007 also offer psychoanalysis an opportunity to renew its vitality as a discipline, after decades of being eroded by our long‐term retreat into private practice? Illustrated in the film From Here to Eternity, through characters played by Burt Lancaster, Montgomery Clift and Frank Sinatra, this Preview shows how applied psychoanalysis can once again aspire to become a universal, genuinely popular, relevant professional discipline. How would we engage ethically with psychiatric casualties of war, for example, within an evidence‐based practice framework today? A novel, brief psychoanalytic treatment for depression, Dynamic Interpersonal Therapy, was developed for use in the UK's Improving Access to Psychological Therapies (IAPT) programme. It is recommended by NICE (National Institute for Health and Care Excellence) as cost‐effective for treating depression. By engaging with evidence‐based practice in this way—as Street Level Bureaucrats—we can reclaim our position at the centre of contemporary publicly funded mental health services.
Big Data capability and sustainability oriented innovation: The mediating role of intellectual capital

The past decade has seen the rapid emergence of research on Big Data and its implications in our society, yet research on its impact on organizations' sustainability challenges is still at an early stage. Based on the organizational learning theory, we develop a framework to investigate the effects of Big Data capability (BDC) and further intellectual capital on a firm's sustainability‐oriented innovation performance (SIP). Using a multi‐source data collected from 358 Chinese firms, we tested our proposed hypotheses using the partial least squares‐structural equation modeling (PLS‐SEM) and the fuzzy‐set qualitative comparative analysis (fsQCA). The results show that BDC is positively related to SIP and economic innovation performance (EIP), mediated by intellectual capital. The fsQCA results further reveal that three configurative combinations, that is, “external capability‐internal resource promotion,” “external capability and relationship building help,” and “external relationship collaboration compensation,” can lead to high SIP. This study provides new insights for firms to develop sustainability‐oriented innovation and to coordinate sustainability innovation and economic innovation practices in order to create balanced outcomes.

A subscapular system free‐flap is extremely useful for maxillofacial reconstruction since it facilitates the simultaneous harvesting of multiple flaps using one subscapular artery (SSA) alone. However, cases of aberrations in the SSAs have been reported. Therefore, the morphology of SSA needs to be confirmed preoperatively before harvesting the flaps. Recent developments in imaging, such as three‐dimensional (3D) computed tomography angiography (3D CTA), facilitate obtain high‐quality images of blood vessel images. Therefore, we examined the utility of 3D CTA in navigating the course of the SSA before harvesting subscapular system free‐flaps. We examined the morphology and aberrations of the SSA using 39 sides of the 3D CTA data and 22 sides of Japanese cadavers. SSAs can be classified into types S, I, P, and A. Type S SSAs are significantly long (mean length = 44.8 mm). Types I and P SSAs have short mean lengths, measuring ≤2 cm in approximately 50% of cases. In type A, the SSA is absent. The frequency of types S, I, P, and A SSAs were 28.2%, 7.7%, 51.3%, and 12.8%, respectively. Type S can be advantageous for harvesting the SSA in subscapular system free‐flaps, because it is significantly longer. In contrast, types I and P might be dangerous because their mean lengths are shorter. In type A, caution is needed not to injure the axillary artery because the SSA is absent. When surgeons need to harvest the SSA, presurgical 3D CTA is recommended.
Variation in the anterior talofibular ligament and the impact of sex, height, weight, and age
Authors: Schoonover Charles , Wright Barth
Published: May 2023

The anterior talofibular ligament (ATFL) is one of the lateral ankle ligaments stabilizing the ankle joint, primarily involved with restricting foot supination. There has been limited research on precise ATFL anatomy and variations, and several studies have conflicting results. The objective of this study was to determine if a correlation exists between ATFL variation and sex, height, weight, and age. In this study, 15 male ankles and 24 female ankles were dissected free of overlying structures to reveal the ATFL, which was classified based on the number of fascicles. Nine of the ligaments had one fascicle, 13 had two incompletely separated fascicles, 12 had two completely separated fascicles, and three had three fascicles. Two ankles had no ATFL. Ligament length and width were measured using the program ImageJ; average length was 19.2 mm and average width was 9.59 mm. Male ligaments were longer and wider than female ligaments. A multivariate regression model was used to assess the influence of sex, height, weight, age, ligament length, and ligament width in predicting ligament variant type; these factors were determined to have no influence. This study found a large amount of ATFL variability, but no correlation between height, weight, age, ligament length, ligament width and ATFL variation. Male ligaments were longer and wider than female ligaments.
