Role of ACE2 polymorphism in COVID-19: impact of age
Authors: Mohaghegh Sadra , Motie Parisa , Motamedian Saeed Reza 
Published: May 2021

Abstract
More than 2 million people have died as a result of the COVID-19 outbreak. Angiotensin-converting enzyme 2 (ACE2) is a counter-regulatory enzyme that converts angiotensin-2 to Ang-(1–7) form in the renin-angiotensin system. Several studies have been analyzed the correlation between ACE2 and COVID-19. Indeed, ACE2/Ang (1–7) system protects the lung against acute respiratory distress syndrome by its anti-inflammatory/anti-oxidant function. However, SARS-Cov-2 can use ACE2 for host cell entry. Expression of ACE2 can be altered by several factors, including hypertension, diabetes and obesity, which also could increase the severity of COVID-19 infection. Besides, since androgens increase the expression of ACE-2, males are at higher risks of COVID-19 infection. Although reported statistics showed a significantly different infection risks of COVID-19 between adults and children, the reason behind the different responses is still unclear. This review proposes the effect of ACE polymorphism on the severity of SARS-COV-2 induced pneumonia. The previous meta-analysis regarding the effect of ACE polymorphism on the severity of pneumonia showed that polymorphism only affects the adult’s illness severity and not the children. Two recent meta-analyses examined the effect of ACE polymorphism on the prevalence and mortality rate of COVID-19 and reported contradicting results. Our opinion paper suggests that the effect of ACE polymorphism on the severity of COVID-19 depends on the patients age, same as of the pneumonia.

Abstract
Recently, structural monitoring technology invested in methodologies that give direct information on structures’ stress state. Optic fibers, strain gauges, pressure cells give real-time data on the stress condition of a structural element, often determining the area where peak stresses have been reached, with a clear advantage over other less direct monitoring methodologies, such as, e.g., the use of accelerometers and inverse analysis to estimate internal forces. In addition, stresses can be recorded in a data log for analysis after a loading event, as well as for taking into account the lifelong stress state of the structure. Beams and columns of a reinforced concrete frame can be effectively monitored for flexural loads. Differently, thin shells are most of their lifespan under membrane regime, and, when properly designed, they rarely move to the bending regime. Our proposal is to monitor the stress in thin structures by small-sized low-cost devices able to record the stress history at key locations, sending alerts when necessary, with the aim of ensuring safety against the risk of collapse, or simply to perform maintenance/repairing activities. Such devices are realized with cheap off-the-shelf electronics and traditional strain gauges. The application examples are given as laboratory tests performed on a reinforced concrete plate, a masonry panel, and a steel beam. Results shows that the permanent monitoring control of stresses can be conveniently carried out on new structures using low-cost devices of the type we designed and realized in-house.

Abstract
Bats are mammals of great ecological and medical importance, which have associations with different pathogenic microorganisms. DNA barcoding is a tool that can expedite species identification using short DNA sequences. In this study, we assess the DNA barcoding methodology in bats from the Colombian Northern region, specifically in the Córdoba department. Cytochrome oxidase subunit I (COI) gene sequences of nine bat species were typified, and their comparison with other Neotropic samples revealed that this marker is suitable for individual species identification, with ranges of intra-species variation from 0.1 to 0.9%. Bat species clusters are well supported and differentiated, showing average genetic distances ranging from 3% between Artibeus lituratus and Artibeus planirostris, up to 27% between Carollia castanea and Molossus molossus. C. castanea and Glossophaga soricina show geographical structuring in the Neotropic. The findings reported in this study confirm DNA barcoding usefulness for fast species identification of bats in the region.

Abstract
As the use time of concrete structures increases, defects such as concrete cracks, corrosion and exposure of steel bars gradually appear, resulting in additional repair of concrete structures to increase their durability and life. In this article, the effects of nano-modified polymer cement-based materials as repair material on the bending behavior of repaired concrete beams were studied. Based on the moment, deflection, strain, surface quality and cracking development monitor of repaired concrete beams, the bending behavior of repaired beams with polymer, nano-modified polymer and fibers was compared and the failure mechanism of the beams was analyzed. The results showed that the nano-modified polymer cement-based materials are helpful in improving the performance of repaired beams, manifested by the increase in the ultimate bending moment and the significant improvement in the quality of the interface between repair and matrix concrete. Compared with polymer cement-based materials, nano-modified polymer cement-based materials result in a 27% increase in ultimate bending moment of the repaired beam and a 58% increase in cracking moment, while reducing the total number of cracks by 23% and the average width of cracks by 17% in the repaired beam. This article demonstrated the availability of nanomaterials for improving the loading behavior of structural components with polymer-modified cement-based materials.
The White Working Class and the Politics of Race in the United States
Authors: Palley Howard A. 
Published: May 2021

Abstract
The Declaration of Independence asserts that “All men are created equal, and that they are endowed by their Creator with certain inalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” Nevertheless, the United States, at its foundation has been faced with the contradiction of initially supporting chattel slavery --- a form of slavery that treated black slaves from Africa purely as a commercial commodity. George Washington and Thomas Jefferson, both of whom had some discomfort with slavery, were slaveholders who both utilized slaves as a commodity. Article 1 of our Constitution initially treated black slaves as three-fifths of a person for the purposes of apportioning representation in order to increase Southern representation in Congress. So initially the Constitution’s commitment to “secure the blessings of liberty to ourselves and our posterity” did not include the enslaved black population. This essay contends that the residue of this initial dilemma still affects our politics --- in a significant manner.
The Inventory of Physical Activity Barriers for Community-Dwelling Adults 50 Years of Age and Older: Development and Preliminary Validation
Authors: Wingood Mariana , Gell Nancy , Peters Denise , Hutchins Tiffany 
Published: May 2021

Background:
Health care providers, including physical therapists, need to identify the reasons for insufficient physical activity (PA) to assist the 56% to 73% of community-dwelling adults 50 years of age and older who are not performing the recommended 150 minutes of moderate to vigorous PA. Currently, there is no feasible, multifactorial tool to assess PA barriers among this population. Without a tool, health care providers must either rely on self-generated questions or collate results from multiple assessments to identify PA barriers related to personal, social, and environmental factors, which can be time-consuming and incomplete.

Purpose:
To develop the Inventory of Physical Activity Barriers (IPAB), an assessment tool that examines personal, social, and environmental PA barriers.

Methods:
We developed and psychometrically evaluated the IPAB using a 3-phase process. For phase 1, we used a deductive method to develop the initial scale. During phase 2, we refined the scale and explored its psychometric properties by collecting cross-sectional pilot data on community-dwelling adults 50 years of age and older. We used descriptive statistics, item-scale correlations, construct validity via Mann-Whitney U test, and internal consistency via Cronbach α to analyze the data from phase 2. After identifying the scale's potential for being valid and reliable, we implemented phase 3, a modified Delphi technique.

Results:
Using item-scale correlations, descriptive statistics, and consensus among PA experts, we refined the initial scale from 172 items to 40 items. The 40-item IPAB demonstrated good construct validity (determined by the scale's ability to differentiate between individuals who did and did not meet 150 min/wk of moderate to vigorous PA; P = .01) and internal consistency (Cronbach α of 0.97).

Conclusion:
Our preliminary results suggest that the IPAB is valid and reliable. Using the IPAB, health care providers will be able to identify patients' PA barriers and thus develop individualized PA prescriptions, an evidence-based method of increasing PA.
Plyo-Accentuated Eccentric Loading Methods to Enhance Lower Limb Muscle Power
Authors: Handford Matthew J. , Rivera Fernando Martín , Maroto-Izquierdo Sergio , Hughes Jonathan D. 
Published: May 2021

ABSTRACT
Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power-based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power-based movements.

AbstractBackgroundSocial communication disorder (SCD) is a neurodevelopmental disorder that includes communication difficulties. Literature linking SCD and addictions is scarce, and there are only a few case reports regarding the co-occurrence of addiction and autism disorder spectrum, and only one of them addressed behavioural addictions.Case presentationWe report MC’s case, who displayed an SCD and sexual addiction (SA). Clinical and neuropsychological evaluations suggested an alteration of social cognition, especially of affective theory of mind. This article also presents the adaptation made of the usual treatment.DiscussionThis case report illustrates the importance of social cognition abilities in the development and maintenance of behavioural addictions, and specifically SA. It also highlights the possible comorbidity of these two disorders and the possibility to work on social cognition as an alternate therapy in the treatment of behavioural addictions.ConclusionsThe co-occurrence of SCD and a behavioural addiction triggered clinical adaptations and implications that may affect a patient’s treatment presenting one of these disorders.

AbstractThe paper presents a study of a Lower Carboniferous (Visean) clastic sequence commonly called Bobrikovsky Formation, deposited in the Volga-Ural Petroleum Province, Orenburg Region. Our investigation included sedimentological description of core samples from hydrocarbon wells and well log correlations. Facies were identified by well log patterns and calibrated by core sedimentology. The Bobrikovsky Formation is proposed to be interpreted as an overall transgressive-regressive succession in a nearshore-tidal environment. Transgressive lagoon-estuary and barrier island facies became regressional lagoon fill-type settings.

La contribución para la educación y promoción cooperativa y otros fines de interés público — COFIP— en la ley vasca y su aplicabilidad
Authors: Gondra Elguezabal Gotzon 
Published: May 2021

Una de las principales particularidades del régimen económico de las sociedades cooperativas es, sin duda, la existencia de un fondo obligatorio cuya aplicabilidad viene expresamente regulada, no siendo los importes dotacionales que la conforman disponibles por los administradores. Se trata de la denominada por el legislador vasco como Contribución para la educación y promoción cooperativa y otros fines de interés público. Si bien las especialidades de la naturaleza jurídica y las finalidades perseguidas por dicho Fondo vienen siendo, ya de antiguo, materias de interés para su investigación, se estima que tanto la aprobación de la nueva legislación cooperativa autonómica como la explícita referencia al fondo contenida en la legislación aprobada al objeto de la ordenación de la situación excepcional de alarma por la COVID-19 invitan a profundizar en el estudio de su evolución jurídica y práctica (eventuales y potenciales destinos).
