Docking Simulations Exhibit Bortezomib and other Boron-containing Peptidomimetics as Potential Inhibitors of SARS-CoV-2 Main Protease
Authors: Vega-Valdez Iván R , Melvin N. Rosalez , José M. Santiago-Quintana , D. Farfán-García Eunice , Marvin A. Soriano-Ursúa 
Published: November 2020

Background::
Treatment of the COVID19 pandemic requires drug development.
Boron- containing compounds are attractive chemical agents, some
of them act as proteases inhibitors.

Objective::
The present study explores the role of boronic moieties in molecules
interacting on the binding site of the SARS-CoV-2 main protease.

Methods::
Conventional docking procedure was applied by assaying boron-free
and boron-containing compounds on the recently reported crystal structure of
SARS-CoV-2 main protease (PDB code: 6LU7). The set of 150 ligands includes
bortezomib and inhibitors of coronavirus proteases.

Results::
Most of the tested compounds share contact with key residues and pose
on the cleavage pocket. The compounds with a boron atom in their structure are
often estimated to have higher affinity than boron-free analogues.

Conclusion::
Interactions and the affinity of boron-containing peptidomimetics
strongly suggest that boron-moieties increase affinity on the main protease,
which is tested by in vitro assays. A Bis-boron-containing compound previously
tested active on SARS-virus protease and bortezomib were identified as potent ligands.
These advances may be relevant to drug designing, in addition to testing
available boron-containing drugs in patients with COVID19 infection.
Does the presence of maxillary midline diastema influence the perception of dentofacial esthetics in video analysis?
Authors: Chaves Priscila Rios Bomfim , Karam Alexandre Melo , Machado Andre Wilson 
Published: November 2020

ABSTRACT

Objective
To evaluate the influence of a midline diastema on dentofacial esthetic perceptions of orthodontists, restorative dental specialists or prosthodontists, and laypersons in a frontal facial evaluation performed by means of video.

Materials and Methods
Two individuals aged between 20 and 25 years, one of each gender, with presence of a midline diastema were selected. An acrylic resin mockup was made of the maxillary anterior region, simulating ideal conditions of smile esthetics. Four standardized frontal view videos of the complete face were filmed of each individual in the following situations: with the ideal smile (unchanged mockup) and with the presence of midline diastemas of 0.5, 1.0, and 1.5 mm created by the mockup. In all videos, the patient said a certain sentence and, at the end, simulated a posed smile. Dentofacial esthetic perceptions of all four videos of each individual were evaluated by 51 orthodontists, 51 restorative dental specialists or prosthodontists, and 51 laypersons by means of visual analog scales. Data were evaluated using analysis of variance and Tukey post hoc test, with the level of significance set at 5%.

Results
The most attractive videos for all groups of examiners were those without diastema and with a diastema of 0.5 mm, for both the woman and the man. For a diastema of 1 mm or 1.5 mm, the dentofacial characteristics were considered unesthetic.

Conclusions
Diastemas equal to or greater than 1 mm negatively influence dentofacial esthetics in a frontal facial evaluation performed by means of video.

Enhancing the Public Health Role of Community Pharmacists – A Qualitative Research Utilising the Theoretical Domains Framework
Authors: Agomo Chijioke O. , Ogunleye James , Portlock Jane 
Published: November 2020

Introduction: The current global coronavirus (Covid-19) pandemic has once again highlighted the need to enhance the role of community pharmacists in public health. In 2012, the World Health Organisation (WHO) estimated that global deaths due to non-communicable diseases (NCDs) as about 38 million (68%). Most of these conditions are preventable through public health initiatives involving community pharmacists. This study aims to explore strategies enhancing the public health role of community pharmacists.
Methods: Data was collected through telephone interviews, supported by Skype (audio), and recorded using the 'HD Call Recorder for Skype'. The qualitative data software package NVivo (version 10) was used for the storage, retrieval and analysis of data. The constant comparative method of data analysis was used. In addition, the Theoretical Domains Framework (TDF) was used to underpin the research throughout.
Results: This study identified a number of strategies that could enhance the public health role of community pharmacists, some of which include: integrating undergraduate healthcare programmes; broadening the public health knowledge of students and pharmacists; pharmacists working alongside other healthcare professionals; teaching communication methods to students and pharmacists; teaching the use of new technologies and social media; etc. In addition, most of the 14 domains of TDF and several of their constructs were captured in the interview.
Conclusions: To enhance the public health role of community pharmacists, it is necessary to develop pharmacists’ capacity in several areas, particularly as it relates to, the use new technologies and social media in public health; enhancing training of pharmacists/students in public health; empowering pharmacists in public health; as well as teaching communication methods to students and pharmacists. Part of the strategy will also be, to integrate healthcare programmes through interdisciplinary initiatives, and changing the undergraduate pharmacy curriculum to increase its public health content.

Awareness About Dental Hygiene Practices And Oral Health Among Salt Pan Workers In Tuticorin - A Survey
Authors: Shunmugam Kumar Mangal C  , Abilasha R  , Vignesh Ravindran  
Published: November 2020

Oral health & general health go hand in hand as one influences the other. The oral cavity can be called as the gateway to the body as it serves as an entry point to all forms of infection. To attain good oral health, one needs to have knowledge of dietary habits and oral hygiene practices. ​. The extreme weather and hard labour conditions in the salt pans cause a lot of morbidities among the salt workers. These morbidities are aggravated if the salt workers do not protect themselves with personal protective measures. ​From the study, we can infer that the understanding of the mindset of daily wage workers can be key to providing them with dental treatment for their needs. ​The study aims to measure the knowledge and attitude about oral health maintenance and habits among salt pan workers in Tuticorin district. This survey was carried out among salt pan workers in Tuticorin, Tamil Nadu to assess their awareness about common dental health problems and data was collected using a pre-designed questionnaire and samples were assigned using convenience sampling methods. Data were collected after obtaining informed consent and steps were taken to ensure confidentiality at all stages. A maximum of 10 people was asked to visit the clinic to take the survey. It was conducted over a period of 10 days. Both male & female workers were involved in the study. The data was collected and tabulated in an excel sheet. Then the raw data was later transferred to SPSS Software. Salt pan workers generally have dental problems, dermatological problems and musculoskeletal problems as the most common morbidities among them. This study showed that more than 50% of the salt pan workers in Tuticorin have good awareness towards oral health.
¿Integración urbana o enclaves persistentes?
Authors: Ezquerra Isabel 
Published: November 2020

Este trabajo se enmarca en una investigación más amplia sobre los polígonos de vivienda construidos entre los años cincuenta y setenta del siglo XX en España. En ellos, el perímetro resulta ser un elemento esencial, al haberse conformado como fragmentos unitarios determinados por una geometría bien definida. En este artículo, la intención es estudiar, desde la perspectiva del espacio urbano, cómo ha evolucionado el perímetro de esas piezas relativamente autónomas –actuaciones unitarias caracterizadas por la repetición de bloques aislados en ordenaciones abiertas sobre espacios libres–, en contacto con un tejido urbano bien distinto, el de las denominadas 'periferias ordinarias' –crecimientos graduales que adoptan sistemas tradicionales basados en calles y manzanas– que se configuraron en torno a ellos en el mismo periodo. El objetivo es estudiar las transformaciones que se han producido en el espacio perimetral de cuatro conjuntos de vivienda situados en Zaragoza, comparando, mediante análisis gráficos intencionados, la situación en el momento de su construcción con el estado actual. Partiendo de un marco teórico amplio, este análisis pretende poner en relación las diversas situaciones urbanas generadas durante estos más de cincuenta años con conceptos explorados por distintos autores, tales como límite, barrera, borde o sutura. El resultado permite evaluar cómo, en algunos casos, la disolución del perímetro de dichos conjuntos de vivienda ha favorecido procesos de relativa integración urbana mientras que, en otros, su consolidación ha contribuido a que persista la condición inicial de enclave.
Productivity Analysis of Micro-Trenching Using Simphony Simulation Modeling
Authors: Vaseli Hediyeh , Hashemian Leila , Bayat Alireza 
Published: November 2020

Micro-trenching is an innovative method for installing fiber optic cable in residential areas and business districts which minimizes surface scarring and potential negative social and environmental impacts. This method has three major steps including cutting a narrow trench in the pavement, cable installation and trench backfilling. This paper discusses a Simphony simulation model of the micro-trenching procedure and analyzes its productivity. Brief descriptions of the micro-trenching method and two field installations used to validate the model are included. A simulation model was developed for two different installation depths of 7.6 and 23 cm using two different methods. To provide an estimation of project duration, the impact of weather conditions on micro-trenching productivity was also considered. The developed model can be used for what if scenarios and for predicting the outcomes, which may be useful for studying the procedure and verifying if any productivity improvement can be achieved. The results indicate that the influence of installation depth is more significant than the impact of weather conditions. Reducing installation depth from 23 cm to 7.6 could improve productivity up to 50% while cold weather condition can reduce productivity by 18.8%. The simulation model demonstrates that the productivity can be improved up to 16% by overlapping two steps during the installation process: starting the cleaning procedure when a portion of cutting is completed.

Influence of Temperature and Relative Humidity on Air Pollution in Addis Ababa, Ethiopia
Authors: Fikeraddis Mulu , Endeshaw Lake 
Published: November 2020

In this paper we access the effects of two atmospheric variables (temperature and relative humidity) on two important pollutants in the atmosphere (Nitrogen oxides (NOx) and carbon monoxide (CO)) by using one year (2016) data of Addis Ababa. Temperature has impact on atmospheric mixing and cause for the reduction of NOx as temperature increases. There are positive correlation between temperature and CO concentration from January to April with (R2 = 0.69), negative correlation from May to August with (R2 = 0.92) and no correlation for the remaining months. NOx and CO have moderate positive and negative correlation with relative humidity during the months January-April (R2 = 0.294 for NOx and R2 = 0291 for CO) and in the months May-August are R2 = 0.97 and R2 = 0.15 for NOx and CO respectively. But there are no clear correlation between the NOx and CO with relative humidity from September-December. NOx concentrations during wet season was almost about twice that of the dry season, but no such difference was observed in the case of CO. The seasonal average air temperature in wet season is relatively lower than dry season. NOx exhibited positive and CO negative seasonal correlations with relative humidity.
