Published: November 2020

El objetivo del presente trabajo es revisar la literatura que ha comparado el efecto de la actividad física (AF) en entornos naturales (AFMN) y artificiales (AFEA) sobre la atención selectiva (AS). Para ello se ha realizado una búsqueda en diferentes bases de datos como PubMed, Google académico y Sports DISCUS. Todas las búsquedas se realizaron desde el enero de 2000 hasta diciembre de 2019 a través de palabras clave como atención selectiva, ejercicio verde, actividad física, universitarios o estudiantes. Se excluyeron los artículos en los que la población no fuera exclusivamente estudiantes universitarios o no se especificaran variables metodológicas como el tipo de ejercicio realizado o el test de medición de la AS. Se seleccionaron un total de seis artículos que cumplieron todos los criterios de inclusión. Del análisis de estas investigaciones se concluye que la AFMN no presenta un efecto significativamente superior en la AS en comparación con la AEFA. La implementación de diversas mejoras metodológicas sería necesaria en futuras investigaciones.
The aim of the present work is to review the bibliography that has compared the effect of physical activity (PA) performed in different environments, such as natural (AFMN) and artificial (AFEA), on directed attention (SA). For this purpose, a search has been made in different databases such as PubMed, Google academic and Sports DISCUS. All the searches were done from January 2000 to December 2019 using keywords such as directed attention, green exercise, physical activity or university students. In addition, articles were excluded if the population was not exclusively university students or if methodological did not specify variables such as the type of exercise performed or the AS measurement test. A total of six articles were selected which fully met the inclusion criteria. From the analysis of these investigations it was concluded that the effect of the AFMN is not significatively greater than the AEFA on the SA. Several methodological improvements are recommended for future research.

La actividad física influye positivamente en la salud de las personas, teniendo un papel fundamental en la prevención, tratamiento, control y rehabilitación de las enfermedades crónicas no transmisibles. El objetivo del estudio es analizar la relación entre la práctica de actividad física y los factores de riesgo cardiovascular. Estudio transversal y correlacional mediante un cuestionario con una muestra de 160 participantes. Los resultados muestran que el 70% de la muestra manifiesta no hacer prácticamente actividad física frente a un 33% que afirma realizar una actividad física moderada/alta. De las variables relacionadas con el riesgo cardiovascular sexo, glucemia y tensión arterial sistólica se encuentran asociadas con el grado de actividad física de forma significativa (p<.05). Es fundamental reforzar la educación sanitaria a toda la población para mantener una adecuada actividad física y otros estilos de vida saludables que repercutan en la disminución de las enfermedades crónicas prevenibles.
Physical activity has a positive influence on people's health, playing a key role in the prevention, treatment, control and rehabilitation of chronic non-communicable diseases. The aim of the study is to analyse the relationship between the practice of physical activity and cardiovascular risk factors. Cross-sectional and correlational study using a questionnaire with a sample of 160 participants. The results show that 70% of the sample stated that they did not do much physical activity compared to 33% who stated that they did moderate/high levels of physical activity. Of the variables related to cardiovascular risk, sex, glycemia and systolic blood pressure are significantly associated with the degree of physical activity (p<.05). It is essential to strengthen health education for the entire population in order to maintain adequate physical activity and other healthy lifestyles that will have an impact on reducing preventable chronic diseases.

Published: November 2020

Uno de los aspectos principales, durante el proceso de formación del alumnado y de su inserción en el mercado laboral, es el nivel de desarrollo social del mismo. Mediante este estudio, con un diseño descriptivo, exploratorio y de corte transversal; se analizan las habilidades sociolaborales autopercibidas por el alumnado de formación profesional de un instituto de Ceuta. La muestra estaba formada por 100 individuos (86 mujeres y 14 hombres). El instrumento empleado fue el Test de factores sociopersonales para la inserción laboral de los jóvenes de Martínez-Rodríguez y Carmona (2010). En cuanto al nivel de estudios, el alumnado que procede de ciclos formativos de grado superior cuenta con mayor nivel de habilidades sociolaborales que aquel que accede con otras titulaciones. Respecto a la situación laboral del alumnado, quienes trabajan cuenta con mayores niveles de habilidades sociolaborales que los alumnos desempleados.
One of the main aspects, during the student training process and its insertion in the labor market, is its level of social development. Through this study, with a descriptive, exploratory and cross-sectional design; the self-perceived socio-labor skills by the professional training students of a Ceuta institute are analyzed. The sample consisted of 100 individuals (86 women and 14 men). The instrument used was the Test of sociopersonal factors for the labor insertion of the young people of Martínez-Rodríguez & Carmona (2010). Regarding the level of studies, students who come from higher cycles of vocational training have a higher level of socio-labor skills than students who access other degrees. Regarding the work situation of students, students who work have higher levels of socio-labor skills than unemployed students.
Profils coévolutifs au sein de groupements hétérogènes : cas de PME exportatrices malgaches
Authors: Ralandison Gilde , Milliot Eric , Harison Victor 
Published: November 2020

Pour s’internationaliser, les PME s’impliquent parfois durablement dans des groupements intégrant des acteurs directs locaux (producteurs et/ou transformateurs) et des firmes étrangères chargées de les aider à accéder aux marchés étrangers. Pour identifier et analyser les profils qui contribuent au processus de coévolution des membres de ces groupements hétérogènes, cette recherche examine les conditions qui permettent de créer dans le temps un avantage commun tout en permettant de servir un projet individuel. Deux cas complémentaires de groupements associant des PME exportatrices malgaches et des firmes étrangères sont étudiés, de manière longitudinale et qualitative, pour comprendre un tel processus. Fondée sur une approche abductive, la mise en relation de ces cas permet d’identifier deux profils séquentiels d’acteurs qui conditionnent le potentiel coévolutif des parties impliquées : les profils comportementaux (capacités réactives permettant de faire face aux conditions de l’environnement externe) et les profils managériaux (attitudes proactives contribuant à impacter l’environnement externe).
Les valeurs publiques entre stabilité et dynamisme : une exploration du management public marocain
Authors: Mériade Laurent , El Khamlichi Abdelbari , Sahib Eddine Abdelhak 
Published: November 2020

Les valeurs publiques sont généralement définies comme des « jugements » ou des préférences publiques orientant les actions et comportements des acteurs publics. D’importants travaux les concernant décrivent l’existence de constellations de valeurs publiques (Jorgensen et Bozeman, 2007) disposant de leur propre hiérarchie. Par contre, peu de travaux définissent comment ces assemblages de valeurs publiques fonctionnent.Une quasi-expérience, menée auprès de deux groupes de managers publics marocains, nous permet de mettre en lumière, à partir de deux dynamiques de fonctionnement, les articulations des valeurs publiques au sein de ces assemblages.
When Local Meets Global: How Introducing English Destabilizes Translanguaging Practices in a Cross-Border Organization
Authors: Langinier Hélène , Ehrhart Sabine 
Published: November 2020

Drawing on an interdisciplinary approach combining linguistics and International Business, we suggest that global and local dynamics interact to co-construct specific language practices in an MNC subsidiary situated in a cross-border territory. We show how introducing a foreign language can modify the benefits that these local multilingual practices generate.Employees revert to translanguaging: They combine all their language knowledge, French, German and local vernacular, to make themselves understood. These specific local language practices have an inclusive role that enables low-level employees in the hierarchy to play a linking role between the multinational company subsidiary and its headquarters in Germany.

Published: November 2020

Introduction: Intestinal parasitosis are a public health problem worldwide. There are several risk factors and a high association with some specific labor activities. Objective: The present study assessed the risk factors and prevalence of enteroparasitic diseases in shellfish pickers from one district of Maceió, Alagoas state, Brazil. Methods: Cross-sectional study of 41 female shellfish pickers including parasitological tests in fecal samples and a questionnaire with objective and subjective questions. Sand samples from their working environment were also analyzed. Results: At least one species of parasite was found in 19.51% of the fecal samples. Pathogenic species of Giardia lamblia, Trichuris trichiura, Schistosoma mansoni, Ascaris lumbricoides, Enterobius vermicularis, from the Ancylostomatidae family, and non-pathogenic species of Entamoeba coli were found. Polyparasitism was diagnosed in 37.5% of the positive samples. A total of 57.14% of sand samples contained hookworm larvae. Regarding the risk factor, low educational level was statistically associated to the presence of parasites (p<0.05). Conclusion: Greater investment in basic education is needed to increase the knowledge about preventive measures against parasitic diseases and the promotion food-handling courses in order to change existing inadequate habits in the community. Basic sanitation is also essential in preventing environmental contamination.
DPM1 expression as a potential prognostic tumor marker in hepatocellular carcinoma
Authors: Li Ming , Xia Shengli , Shi Ping 
Published: November 2020

Background
Altered glycosylation of proteins contributes to tumor progression. Dolichol phosphate mannose synthase (DPMS), an essential mannosyltransferase, plays a central role in post-translational modification of proteins, including N-linked glycoproteins, O-mannosylation, C-mannosylation and glycosylphosphatidylinositol anchors synthesis. Little is known about the function of DPMS in liver cancer.

Methods
The study explored the roles of DPMS in the prognosis of hepatocellular carcinoma using UALCAN, Human Protein Atlas, GEPIA, cBioPortal and Metascape databases. The mRNA expressions of DPM1/2/3 also were detected by quantitative real-time PCR experiments in vitro.

Results
The transcriptional and proteinic expressions of DPM1/2/3 were both over-expressed in patients with hepatocellular carcinoma. Over-expressions of DPMS were discovered to be dramatically associated with clinical cancer stages and pathological tumor grades in hepatocellular carcinoma patients. In addition, higher mRNA expressions of DPM1/2/3 were found to be significantly related to shorter overall survival in liver cancer patients. Futhermore, high genetic alteration rate of DPMS (41%) was also observed in patients with liver cancer, and genetic alteration in DPMS was associated with shorter overall survival in hepatocellular carcinoma patients. We also performed quantitative real-time PCR experiments in human normal hepatocytes and hepatoma cells to verify the expressions of DPM1/2/3 and results showed that the expression of DPM1 was significantly increased in hepatoma cells SMMC-7721 and HepG2.

Conclusions
Taken together, these results suggested that DPM1 could be a potential prognostic biomarker for survivals of hepatocellular carcinoma patients.
Wnt16 signaling promotes osteoblast differentiation of periosteal derived cells in vitro and in vivo
Authors: Jin Ying , Sun Xiaoyan , Pei Fang , Zhao Zhihe , Mao Jeremy 
Published: November 2020

Background
Periosteum plays critical roles in de novo bone formation and fracture repair. Wnt16 has been regarded as a key regulator in periosteum bone formation. However, the role of Wnt16 in periosteum derived cells (PDCs) osteogenic differentiation remains unclear. The study goal is to uncover whether and how Wnt16 acts on the osteogenesis of PDCs.

Methods
We detected the variation of Wnt16 mRNA expression in PDCs, which were isolated from mouse femur and identified by flow cytometry, cultured in osteogenic medium for 14 days, then knocked down and over-expressed Wnt16 in PDCs to analysis its effects in osteogenesis. Further, we seeded PDCs (Wnt16 over-expressed/vector) in β-tricalcium phosphate cubes, and transplanted this complex into a critical size calvarial defect. Lastly, we used immunofluorescence, Topflash and NFAT luciferase reporter assay to study the possible downstream signaling pathway of Wnt16.

Results
Wnt16 mRNA expression showed an increasing trend in PDCs under osteogenic induction for 14 days. Wnt16 shRNA reduced mRNA expression of Runx2, collage type I (Col-1) and osteocalcin (OCN) after 7 days of osteogenic induction, as well as alizarin red staining intensity after 21days. Wnt16 also increased the mRNA expression of Runx2 and OCN and the protein production of Runx2 and Col-1 after 2 days of osteogenic stimulation. In the orthotopic transplantation assay, more bone volume, trabecula number and less trabecula space were found in Wnt16 over-expressed group. Besides, in the newly formed tissue Brdu positive area was smaller and Col-1 was larger in Wnt16 over-expressed group compared to the control group. Finally, Wnt16 upregulated CTNNB1/β-catenin expression and its nuclear translocation in PDCs, also increased Topflash reporter luciferase activity. By contrast, Wnt16 failed to increase NFAT reporter luciferase activity.

Conclusion
Together, Wnt16 plays a positive role in regulating PDCs osteogenesis, and Wnt16 may have a potential use in improving bone regeneration.
Modelling the effects ofSpartina alterniflorainvasion on the landscape succession of Yancheng coastal natural wetlands, China
Authors: Dai Lingjun , Liu Hongyu , Wang Gang , Wang Cheng , Guo Ziru , Zhou Yi , Li Yufeng 
Published: November 2020

BackgroundThe Yancheng coastal natural wetlands (YCNR) are well-preserved silty tidal flat wetlands in China. Due to the severe invasion ofSpartina alterniflora, the native ecosystem has undergone great changes. The successful invasion ofS. alterniflorareduced the biodiversity of the YCNR, changed the structure and function of the local ecosystem, and eventually led to the degradation of the ecosystem and the loss of ecosystem function and service. Fully understanding the impact of an alien species invasion on YCNR succession is an important prerequisite for protecting and restoring the wetlands.MethodsIn this study, remote sensing, GIS technology, and a cellular-automaton Markov model were used to simulate the natural succession process of native ecosystems without being affected by alien species. By comparing the landscape of the YCNR with the model simulation results, we gained a better understanding of how alien species affect native landscape-scale ecosystems.ResultsDuring the natural succession of the coastal native wetland ecosystem in the YCNR, the pioneer speciesS. alternifloraoccupied the mudflats and expanded seaward. The whole area expanded and moved seaward with an average annual movement of 58.23 m. Phragmites australis seemed to dominate the competition withS. salsacommunities, and the area gradually expanded with an average annual movement of 39.89 m. The invasion ofS. alterniflorachanged the native ecosystem’s spatial succession process, causing theS. salsaecosystem to be stressed by ecosystems on the side of the sea (S. alterniflora) and that of land (P. australis). The area of the seaward-expandingP. australisecosystem has been declining. Under a reasonable protected area policy, human activities have enhanced the succession rate of the P. australis ecosystem and have had a small impact on the ecological spatial succession ofS. salsaandS. alterniflora.
Association between Subclinical Hypothyroidism and Albuminuria in Patients with Type 2 Diabetes Mellitus: A Cross Sectional Study in Iran
Authors: Najmaldin Atousa , Askari Solmaz , Foroutan Majid 
Published: November 2020

Introduction: Studies have shown the association between subclinical hypothyroidism and type 2 diabetes. However, the common complications of type 2 diabetes, such as diabetic nephropathy and albuminuria with subclinical hypothyroidism, are not fully clear yet. This study thus aimed to determine the association between subclinical hypothyroidism and albuminuria in patients with type 2 diabetes mellitus.
Methods: This was a cross-sectional study, of 140 individuals diagnosed with type 2 diabetes mellitus (DM) admitted to the internal clinics of Kosar Hospital in Semnan, Iran in 2017-2018. The participants were selected, and were compared based on having 2 TSH levels above normal (>4.2 mIU/L) 3 months apart, as well as patients were divided to two groups including, subclinical hypothyroidism group (n=40) and euthyroid group (n=100) based on demographic information, laboratory information and indicators such as albuminuria, and urinary albumin-to-creatinine ratio (UACR).
Findings: The mean and standard deviation of UACR in patients with subclinical hypothyroidism were significantly higher than those of euthyroid patients (46.09 ± 27 9.27 vs. 3.94 ± 0.24 and P = 0.015, respectively). In patients with subclinical hypothyroidism, there was a statistically significant and direct relationship between UACR values with primary TSH level (r = 0.555, P< 0.001) and UACR values with secondary TSH level (r = 0.563, P< 0.001).
Conclusion: Among type 2 DM patients, the rate of albuminuria in subclinical hypothyroidism group was significantly higher than that of euthyroid patients and with increasing initial and recurrent TSH levels, UACR values and consequently albuminuria increased.
