Besson, T, Pastor, FS, Varesco, G, Berthet, M, Kennouche, D, Dandrieux, P-E, Rossi, J, and Millet, GY. Elite vs. experienced male and female trail runners: comparing running economy, biomechanics, strength, and power. J Strength Cond Res 37(7): 1470–1478, 2023—The increased participation in trail running (TR) races and the emergence of official international races have increased the performance level of the world best trail runners. The aim of this study was to compare cost of running (Cr) and biomechanical and neuromuscular characteristics of elite trail runners with their lower level counterparts. Twenty elite (10 females; ELITE) and 21 experienced (10 females; EXP) trail runners participated in the study. Cr and running biomechanics were measured at 10 and 14 km·h−1 on flat and at 10 km·h−1 with 10% uphill incline. Subjects also performed maximal isometric voluntary contractions of knee and hip extensors and knee flexors and maximal sprints on a cycle ergometer to assess the power-torque-velocity profile (PTVP). Athletes also reported their training volume during the previous year. Despite no differences in biomechanics, ELITE had a lower Cr than EXP (p < 0.05). Despite nonsignificant difference in maximal lower-limb power between groups, ELITE displayed a greater relative torque (p < 0.01) and lower maximal velocity (p < 0.01) in the PTVP. Females displayed shorter contact times (p < 0.01) compared with males, but no sex differences were observed in Cr (p > 0.05). No sex differences existed for the PTVP slope, whereas females exhibited lower relative torque (p < 0.01) and velocity capacities (p < 0.01) compared with males. Although not comprehensively assessing all determining factors of TR performance, those data evidenced level and sex specificities of trail runners in some factors of performance. Strength training can be suggested to lower level trail runners to improve Cr and thus TR performance.

Introducción: Cada vez con más frecuencia, la población civil sufre lesiones por proyectil de arma de fuego. El 57% de los pacientes presenta compromiso óseo y la fractura de fémur es la más común. La elevada incidencia y la ausencia de un protocolo estandarizado para su tratamiento motivaron este estudio.
Materiales y Métodos: Estudio retrospectivo, descriptivo. Entre 2019 y 2021, se incluyeron pacientes con fracturas de fémur causadas por arma de fuego. Se analizaron las siguientes variables: región anatómica involucrada, clasificación, tratamiento y complicaciones.
Resultados: La muestra incluyó a 35 pacientes, 25 (71,43%) con fracturas completas y 10 (28,57%), con fracturas incompletas. Según la localización, el fémur distal fue la zona más afectada (48,57%). Veintiséis pacientes fueron tratados mediante reducción y osteosíntesis y 9, de forma incruenta.
Conclusiones: Recurrimos a una clasificación sencilla que divide a las fracturas en completas o incompletas. Todas las fracturas completas se consideraron inestables independientemente de su localización; y las incompletas, estables, salvo las del tercio proximal, donde es conveniente realizar una fijación profiláctica. Las fracturas diafisarias incompletas pueden tratarse de forma incruenta y todas las fracturas completas se trataron con reducción y osteosíntesis. El clavo endomedular es el método de elección para las fracturasen las zonas I y II. En la zona III, se requiere un análisis individualizado para cada patrón. Creemos que el manejo inicial y la correcta selección del implante según la zona afectada son factores determinantes para lograr resultados satisfactorios.

Background and Objectives: This study aimed to investigate epidemiology of Staphylococcus epidermidis (S. epidermidis) and Acinetobacter baumannii (A. baumannii) infections in neonatal intensive care unit (NICU) in a period of 8 years.
Materials and Methods: This retrospective cohort study was conducted on 46 cases of nosocomial infection by S. epider- midis, and 44 neonates with A. baumannii in NICU of Valiasr hospital, Iran.
Results: The trend of A. baumannii and S. epidermidis infection were as follows: 1 and 7 in 2014, 11 and 7 in 2015, 20 and 11 in 2016, 1 and 4 in 2017, 4 and 6 in 2018, 4 and 4 in 2019, 0 and 1 in 2020, and 3 and 6 in 2021-March 2022 respectively. Mortality proportion (%) in neonates with S. epidermidis and A. baumannii infection was at 8.3 and 32.1, respectively. There was a strong positive correlation between number of infected neonates in month and average of prescribed antibiotics before incidence of infection in every baby in that month. Fluconazole prescription before incidence of infection were associated with the A. baumannii infection in month too. Amikacin prescription had adjusted correlation on increasing of A. baumannii and S. epidermidis infection in month.
Conclusion: It seems reducing of hospitalization duration and medication prescriptions management plays an important role in reducing of nosocomial infections

Abstract
Induced breeding of Macrognathus aculeatus was carried out in order to determine the most appropriate dose of carp pituitary extract (CPE) and OVAFISH hormone. The best dose of CPE was 100 mg/kg body weight of female and 45mg/kg body weight of male with fertilization rate 81.34% and the best dose of OVAFISH was 1.5 ml/kg body weight of female and 0.75 ml/kg body weight of male with fertilization rate 91.96%. The fertilized eggs were round, sticky, demersal in nature and greenish in color. The perivitelline space of fertilized eggs was observed in 17 min. The First cleavage appeared at 56 min after fertilization (AF), producing two equal blastomeres. The cell division was completed in 4.17h. The fertilized egg took 6.47, 10.54, and 15.12 h to reach morula, blastula, and gastrula stage respectively. The eggs were hatched 34.17h AF at 27-28°C. Five days old post-hatchlings were reared for four weeks in a 160 L tanks using four different diets i.e., artificial feed, mix zooplankton, artemia nauplii and egg custard. The finding showed that hatchlings fed on mix zooplankton had a higher specific growth rate (SGR) (9.60±0.25). The significantly higher mean survival rate was also observed in larvae fed with mix zooplankton (47.67±11.25%) followed by artemia nauplii (38.5±5.4%) and artificial powdered feed (18.17±3.68%) for 28 days experiment. Our finding suggests CPE best dose @ 100mg/kg body weight for female and 45 mg/kg body weight for male and best dose of OVAFISH @1.5 ml/kg body weight of female and 0.75 ml/kg body weight of male for induced breeding. While in larval rearing experiment highest survival and growth rate was obtained in the larvae fed with mix zooplankton for 28 days trial.

Abstract

Minerals are important for animals in many biological functions, there is scarce information however about micromineral content in blood of South American camelids under their prevalent production system. This study aims to determine the content of selenium in whole blood and zinc in blood serum of grazing alpacas at three different physiological states in the Peruvian Andes. Fifteen female alpacas on native pastures of the Andes were included in this study. Blood samples were collected for measurement of selenium in whole blood and zinc in blood serum from female alpacas at pre-calving, ten days after calving, and late lactation, as well as their respective offspring. Selenium and zinc content of pastures consumed by alpacas also were determined. The content of Se and Zn of the diet selected by alpacas met the requirements for the physiological states they go through in comparison with literature references. The concentration of zinc in blood serum of female alpacas was higher ten days after calving (0.26 µg/ml), compared to pre-calving and late lactation. The same tendency was found in the case of their offspring at ten days after calving (0.23 µg/ml) higher than for late lactation. Unlike zinc, in the case of selenium, no differences were found between the physiological states studied for alpacas or their offspring. Apparently, the zinc serum concentration changes through productive cycle of alpacas but not the whole blood selenium concentration. Further investigation is needed to define alpaca adequacy of zinc and selenium in relation to blood content of both minerals.

Abstract
Purpose
To analyze the clinical efficacy of total laparoscopic π-shaped esophageal jejunostomy and laparoscopic assisted Roux en-Y esophago-jejunostomy for cardiac cancer and their effects on traumatic stress.
Methods
We collected clinical data from 72 patients with adenocarcinoma of the esophagogastric junction who were treated in our department between June 2020 and July 2022. All patients underwent laparoscopic total gastrectomy + D2 lymphadenectomy, in whom 38 patients underwent total laparoscopic total gastrectomy with π-shaped esophageal jejunostomy and 34 patients underwent laparoscopic-assisted total gastrectomy with Roux en-Y esophago-jejunostomy. The short-term therapeutic effects, safety and effects on stress response indicators of different surgical methods were analyzed.
Results
There were no significant differences in baseline clinical and pathological data between the two groups (P > 0.05). The mean operation duration was 201.7 ± 80.3 minutes in the total endoscopic π-shaped esophageal jejunostomy group, which was longer than 166.9 ± 26.9 minutes in the laparoscopic-assisted Roux en-Y esophago-jejunostomy group (P < 0.05). The length of the surgical incision in the total endoscopic π-shaped esophageal jejunostomy group was significantly shorter, measuring 4.6 ± 2.1 cm, compared to the Roux-en-Y anastomosis group, which had an average length of 10.4 ± 2.1 cm (P < 0.01). In terms of intraoperative bleeding, the intraoperative bleeding volume of 130.3 ± 50.3 ml in the total endoscopic π-shaped esophageal jejunostomy group was significantly lower than that of 167.2 ± 72.8 ml in the laparoscopic-assisted Roux en-Y esophago-jejunostomy group (P < 0.05). Postoperative recovery time to exhaust was 3.8 ± 1.2 days in total endoscopic π-shaped esophageal jejunostomy group, significantly lower than 5.0 ± 2.0 days in laparoscopic-assisted Roux en-Y esophago-jejunostomy group (P = 0.003). In terms of postoperative extubation time, postoperative hospital stay, postoperative complications and the number of dissected lymph nodes, there were no significant differences between the total endoscopic π-shaped esophageal jejunostomy group and the laparoscopic-assisted Roux en-Y esophago-jejunostomy group (P > 0.05). In terms of stress indicators, there were no significant differences in stress indicators between the two groups before surgery, and the serum levels of CRP, cortisol (COR) and IL-6 in the π anastomosis group were significantly lower than those in the Roux en-Y esophago-jejunostomy group on postoperative days 3 and 5 (P < 0.05).
Conclusion
Total laparoscopic total gastrectomy with π-shaped esophageal jejunostomy demonstrates safety and feasibility. This surgical approach effectively reduces intraoperative bleeding, accelerates patient recovery time, minimizes postoperative pain, lowers the risk of complications, and minimally impacts the body's traumatic stress response.

Published: June 2023

Abstract
Purpose: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive carcinoma without reliable non-invasive screening tests. This study aimed to identify and evaluate novel and reliable noninvasive serological biomarkers for screening PDAC.
Methods: We performed global proteome profiling of 67 PDAC tumor tissues and 67 matched normal adjacent tissues by mass spectrum to identify new biomarker in Ruijin cohort 1. This is further verified in proteome and mRNA sequencing data in published cohort by CPTAC. Next, COL12A1 and CA199 serological levels were determined in 47 PDAC sera and 75 healthy sera by enzyme immunoassay in Ruijin cohort 2.
Results: Finally, collagen type XII alpha 1 chain (COL12A1) was identified as a candidate for PDAC diagnosis in Ruijin cohort 1, and was validated to be higher in tumor tissues than the normal adjacent tissues (NATs) in CPTAC cohort. In addition, COL12A1 protein was significantly higher in case sera than control sera. The ROC analysis revealed that COL12A1 improved the performance of CA199 in discriminating PDAC from healthy individuals (AUCCA199 = 0.91 vs AUC CA199 + COL12A1 = 0.95, p < 0.05). COL12A1 also showed perfect ability to distinguish early-stage PDAC from healthy individuals (AUCCOL12A1 = 0.83), and was observed to significantly improve AUC of CA199 in stage I-II PDAC (AUCCA199 = 0.92 vs AUCCA199+COL12A1 = 0.97, p < 0.05).
Conclusion: This study reveals that COL12A1 is a potential serological diagnostic marker that complements CA199 in detecting early-stage PDAC. It is necessary for a large-scale study to validate the results.

Published: June 2023

Abstract

While many children suffer from stress due to school-related factors, some alternative schooling systems, such as the Montessori pedagogy, emphasize stress-free learning environments (e.g., no grades, no tests, peer-peer learning). This study compared brain markers of stress, i.e., hippocampus, amygdala, and medial prefrontal cortex (mPFC) volumes, as a function of school experience. A cross-sectional comparative morphometric study was run between 45 traditionally schooled children and 44 Montessori-schooled children (3-12 years). While both groups were comparable in terms of cognitive abilities, socio-economic environment, and anxiety levels, volumetric values within their hippocampus and their mPFC differed. While there was hippocampal growth across development for all participants, there was a higher gain for Montessori-schooled children. Furthermore, female traditionally schooled children showed a loss in hippocampal and mPFC volume across age, while female Montessori-schooled children showed a gain. It seems that traditional pedagogical approaches induce mild but chronic stress, affecting underlying brain structures.

Authors: Del Mohammad Sadegh Taher Tolou , Sadat Seyyedah Ashraf 
Published: June 2023

Abstract
Motion and stillness are necessary for architectural perception. Architectural space causes physical, visual and mental health mobility in the observer due to its mobility, fluidity and pause properties. In philosophy, the factor of motion is the basis of the perception of the truths of the material world, and journey of horizons and stillness is the basis of the perception of the truths of the spiritual world and the spiritual journey. The present study aims to perceive the space of a house by creating mobility and stillness. The present study is of qualitative analytical-descriptive type. The present study is an applied research that has been developed by descriptive-analytical method, with an emphasis on logical reasoning. At this stage, 10 houses of the Qajar period of Tehran are identified, compared, and analyzed through field observations and logical reasoning in the field of mobility and stillness. The research findings indicate that the average percentage of outdoor mobility in the spaces of historic houses in the Qajar period is 54.25% and the percentage of indoor mobility is 62.95%. The percentage of stillness in the interior of the houses is 30.55%. The results of the study show that in the houses of Qajar period of Tehran, the spaces of mobility inside the house are more than the still spaces, indicating the importance of mobility in the spaces of houses of Qajar period. The amount of outdoor mobility of the house is more than the green spaces and fountains, showing the attention to mobility, mobility and activity outside the house.

Abstract
From changes in the interest rate to the hijacking of a commercial aircraft, there are many events that may result in a fluctuation in airline stock performance. Theimpact of US airlines’ stock performance was measured following aviation related news announcements on differing topics. The data accounted for aviation news of airlines, airports, regulations, safety, accidents, manufacturers, MRO, incidents, aviation training, general aviation, and others from Aviation Voice. A natural language processing, Latent Dirichlet Allocation (LDA), was utilized to investigate and search for patterns that can explain the movements of US airline stocks. First, the aviation related data was mined through text mining and topic modeling. Second, the LDA model approach was employed to help identify and capture certain topics mentioned in aviation voice news releases. Finally, the links between stock returns and the topics identified were investigated. The findings show that financial performance varies significantly across topics. Topics related to technology, fuel, and training positively affect the US airline stocks in the short and long terms moving average, while defense and travel cost-relatedtopics only affect the medium-term run.

Published: June 2023

Abstract
We use topological graphs to generate topological coding, which is a fundamental technology in number theory, algebra, and has potential application value in asymmetric encryption systems. This article proposes a method of using topological graph sequences to generate topological coding for protecting hash ciphers, which can effectively protect hash ciphers even in the event of password leakage. We use topology graphs with labelings and colorings to generate graph lattice, which is the application of graph markers in asymmetric encryption systems. There are various kinds of graph labeling, one of them is a harmonious labeling. In order to further study topological coding, we use the graph harmonious-type labelings and colorings to propose (k, d)-harmonious labelling , since they can be applied to build up a new approach of asymmetric encryption. Finally, several typical attack methods about graph lattice analyzed to verify the effectiveness of our scheme.
The post-disaster economic resilience; a study on the economic impact of flooding, and influence of cash and non-cash assistance across local and refugee population of Cox Bazar, Bangladesh

Published: June 2023

Abstract
Natural disasters (i.e., flooding) exert a substantial impact on the economic activities of the poverty-stricken coastal population of Cox Bazar, Bangladesh. The economic impact of flooding is measured using individual-level data from the Cox Bazar Panel Survey (CBPS) data. Satellite data, such as the Landsat 8, the Shuttle Radar Topography Mission (SRTM) elevation data, and other resources have been used to identify the flooded areas and other geographical changes across the region. The DID results indicate flood-affected individuals had lower employment, longer work hours, and were more likely to seek jobs. However, those with jobs were found to have greater earnings. The 2SLS results indicate that cash and non-cash assistance mediate the relationship between flooding and economic outcomes. Individuals who received cash assistance were better at integrating as they had better employment rates and higher earnings. In contrast, recipients of non-cash assistance had lower employment rates and had no significant effect on earnings. In addition, the propensity score results imply that individuals with similar demographic characteristics, who have received cash assistance compared to those who did not, have lower food shortages and better health. Lastly, the triple difference estimator shows that individuals living in areas with better access to healthcare facilities had greater employment and earnings compared to those who didn’t.

Abstract

Weak flux pinning and weak intergranular coupling are the main constraints of the Bi1.6Pb0.4Sr2Ca2Cu3O10+δ (BiPb-2223) superconductor that restrict its practical applications. It has been shown that introducing artificial pinning centers could enhance flux pinning capability in high-temperature superconductors. In this work, the excess conductivity analyses used to study the effects of Al2O3–15 wt% ZrO2 (AlZr) nanocomposite on the superconducting properties of the BiPb-2223 phase. A series of (BiPb-2223)1−x/(AlZr)x composite samples (0.0 wt% ≤ x ≤ 1 wt%) were synthesized. The XRD results and SEM micrographs showed that adding AlZr nanocomposite up to 0.5 wt% improves the Bi1.6Pb0.4Sr2Ca2Cu3O10+δ phase formation and intergranular coupling. The excess conductivity analyses showed that the Fermi energy EF, Fermi velocity VF, and coherence length along the c axis ξc(0) decrease with increasing the amount of the AlZr nanocomposite. the ξc(0) value decreases from 3.68 Å for AlZr free sample to 2.70 Å for x = 1.0 wt%. Moreover, different superconducting critical parameters, including lower and upper critical magnetic fields (Bc1(0) and Bc2(0)), and critical current density (Jc(0)) are estimated by the Ginsberg-Landau theory. Obtained values indicated a remarkable enhancement in the mentioned critical parameters by adding the AlZr nanocomposite. The Jc(0) value enhances from 1.4×103 A/cm2 for AlZr free sample to 3.5×103 A/cm2 for the sample with 1.0 wt% additives, which shows that the Jc(0) is improved by about 150%. The obtained values also show that the critical magnetic fields are improved by about 80% by adding the 1.0 wt% AlZr nanocomposite. The improvement of the superconducting parameters most likely attributes to the the flux pinning capability and intergranular coupling enhancment.
