Authors: Mehaney Ahmed , Elsayed Hussein A. , Ahmed Ashour M. 
Published: April 2021

Abstract
Detection of blood-carried volatile organic compounds (VOCs) existing in the exhaled breath of human is an attractive research point for noninvasive diagnosis of diseases. In this research, we introduce a novel application of photonic crystals (PCs) for the detection of isoprene traces in the exhaled breath as a biomarker for liver fibrosis. This idea is introduced for the first time according to the best of our knowledge. The proposed sensor structure is a one-dimensional (1D) PC constructed from a multilayer stack of two dielectric materials covered with an air cavity layer filled with the dry exhaled breath (DEB) and a thin metallic layer of Au is attached on the top surface. Hence, the proposed sensor is configured as, [prism/Au/air cavity/(GaN/SiO2)10]. The transfer matrix method and the Drude model are adopted to calculate the numerical simulations and reflection spectra of the design. The essential key for sensing isoprene levels is the resonant optical Tamm plasmon (TP) states within the photonic bandgap. The obtained numerical results are promising such as high sensitivity (S) of 0.321 nm/ppm or 278720 nm/RIU. This technique can be reducing the risk of infection during the taking of blood samples by syringe. Also, it can prevent the pain of patients. Finally, this work opens the door for the detection of many diseases by analyzing the breaths of patients based on photonic crystals.

Published: April 2021

AbstractWith the rapid development of the tourism industry, the water resource consumption in tourism has largely increased and gets more complicated, making water resource management in tourism more difficult. To achieve sustainable water utilization in tourism, water resource management has to take full account of the local natural, social, and industrial conditions, both satisfying the demands of water resource protection and tourism development. To analyze this coupling relationship, an integrated index system comprised of 15 indices is designed, and a coupling degree model between tourism-related water resource management and local conditions is introduced. The result revealed that tourism-related water resource management is generally congruent with the local conditions in China, and provinces at the very high/low coupling stage presented four clusters. A discussion combining the change of water policies and the water use efficiency of hotels in Beijing revealed that water-saving policies are proven to be necessary for the tourism development. Furthermore, a discussion of the four clusters revealed the advanced experience and deficiency of water policies in substantial tourism areas. The results could provide references for the improvement of water policies in the tourism industry in China.

Abstract
Water pollution in China has not only become one of the most vital factors impeding the social-economic development, but also threatening people's health. In this study, Kaifeng was considered as an example, and the human health risk of drinking water pathway from 2010 to 2017 was evaluated on the basis of drinking water hygiene standards and the human health risk assessment model (HHRA). Besides, the human health loss caused by water pollution was quantitatively evaluated through emergy theory and analysis method. The results showed that the carcinogenic annual risk of carcinogenic pollutants ranged from 2.0 × 10−5 to 6.5 × 10−5, and the average health risk of non-carcinogenic pollutants was about 1.5 × 10−8, but the difference between different pollutants was obvious. Affected by water quality, social-economic development, Medicare, etc., the value of human health loss ranked at the top in 2016 with 8.73 × 1018 sej, equivalent to 9.33 million RMB, while in other years, it was around 6 × 1018 sej. It is indicated that among the factors, water quality is the direct inducement of healthy loss, the socio-economic development is the leading force effecting the value, and the Medicare is the final determinant of the public burden.
siRNAs and Viruses: The good, the Bad and the Way Forward
Authors: Soobramoney Cassandra , Parboosing Raveen 
Published: April 2021

:
There are no available antivirals for many viruses or strains, while current antivirals are
limited by toxicity and drug resistance. Therefore, alternative strategies, such as RNA interference
(RNAi) are required. RNAi suppresses gene expression of any mRNA, making it an attractive candidate
for antiviral therapeutics. Studies have evaluated siRNAs in a range of viruses, with some
showing promising results. However, issues with stability and delivery of siRNAs remain. These issues
may be minimized by modifying the siRNA structure, using an efficient delivery vector and
targeting multiple regions of a virus's genome in a single dose. Finding these solutions could accelerate
the progress of RNAi-based antivirals. This review highlights selected examples of antiviral
siRNAs, limitations of RNAi and strategies to overcome these limitations.

Published: April 2021

BackgroundChildren with osteogenesis imperfecta (OI) experience a diversity of symptoms that expose them to difficult physical, mental, and social challenges. Sisom (DHealth) is an interactive assessment and communication tool designed to help children aged 6-12 years with chronic conditions express their symptoms. Recently, the co-design of the Sisom OI paper prototype was launched by seeking the perspectives of end users, including children with OI and their clinicians.ObjectiveThe aim of this study is to describe the experiences that children with OI were prompted to share with researchers during the co-design of the Sisom OI paper prototype.MethodsA secondary analysis of qualitative data was conducted at a university-affiliated, pediatric, orthopedic hospital. The data sources consisted of interview transcripts, drawings, field notes, and observations derived from interviewing 12 children with OI who participated in the co-design of the Sisom OI paper prototype. The themes and subthemes identified from the data sources were generated using qualitative description.ResultsThree themes were identified. The first, Relating to Others, described the balance between feeling different versus feeling similar to other children. The subthemes were Common OI Experience, Feeling Different, and Feeling Just Like Others. The second, Relating to Their Condition, described children’s positive and negative interactions with their own condition and health care. The subthemes were Understanding Their Condition, Special Relationship with the Hospital, and Difficult Treatments and Procedures. The third, Reflecting on Capabilities, described children’s recognition of their strengths and limitations. The subthemes were Perceiving Limitations, Overcoming Isolation, and Celebrating Strengths.ConclusionsThis co-design process provided children with OI the space to not only contribute to the development of the end product but also eloquently describe their experiences. These findings, based on the descriptions given by the children themselves, offer us a unique understanding of what it means to grow up with OI.

Published: April 2021

Background
Due to the influence of the COVID-19 pandemic, conventional face-to-face academic conferences have been restricted, and many of these conferences have moved onto the internet.

Objective
The aim of this study was to investigate the virtual conferences in the field of urology during the COVID-19 pandemic and provide suggestions for better organization of such conferences.

Methods
A cross-sectional survey was conducted from May 30 to June 15, 2020, in China. Our team designed a 23-item questionnaire to investigate the conferences attended by urologists during the COVID-19 pandemic. SPSS 22.0 (IBM Corporation) was applied to analyze the data collected.

Results
A total of 330 Chinese urologists participated in our survey, and the response rate was 89.7% (330/368). Among the participants, 40.9% (135/330) were associate chief physicians. The proportion of participants who took part in conventional face-to-face academic conferences decreased from 92.7% (306/330) before the COVID-19 pandemic to 22.1% (73/330) during the pandemic (P<.001). In contrast, the proportion of urologists who took part in virtual conferences increased from 69.4% (229/330) to 90% (297/330) (P<.001). Most urologists (70.7%, 210/297) chose to participate in the virtual conferences at home and thought that a meeting length of 1-2 hours was most appropriate. Among the urologists, 73.7% (219/297) reported that their participation in the virtual conferences went smoothly, while the remaining respondents reported that they had experienced lags in video and audio streaming during the virtual conferences. When comparing conventional face-to-face conferences with virtual conferences, 70.7% (210/297) of the respondents thought that both conference formats were acceptable, while 17.9% (53/297) preferred virtual conferences and 11.5% (34/297) preferred conventional face-to-face meetings.

Conclusions
Virtual conferences are increasing in popularity during the COVID-19 pandemic; however, many aspects of these conferences could be improved for better organization.

Zeolitas nativas en el tratamiento de agua residual doméstica
Authors: Méndez de los Santos Noemi , López Ocaña Gaspar 
Published: April 2021

En esta investigación zeolitas de río y de cerro fueron evaluadas para ver su potencial en el tratamiento de aguas residuales. En primer lugar, se diseñó y construyó un sistema experimental de tres biorreactores de lecho fijo de flujo ascendente (BLFFA) con una altura de 1.5 metros y diámetro de cuatro pulgadas, seguidamente se evaluó el potencial de las zeolitas nativas y una testigo comercial en el tratamiento de aguas residuales. Se arrancaron los BLFFA con un diseño factorial 3 x 3, operando con zeolita de río, zeolita de cerro y zeolita comercial (control), todas con partículas de ¼ de pulgada, utilizando tres diferentes alturas de lecho (0.75, 0.90 y 1.10 m) y tres tiempos de retención hidráulica (6, 12 y 24 horas). Se evaluaron las variables de respuesta mediante un análisis de varianza multifactorial y para discriminar entre las medias se empleó el método de diferencia mínima significativa (LSD) de Fisher (p < 0.05, 95 % de confianza). La zeolita de cerró presentó (promedio, N = 10) las mejores características fisicoquímicas con densidad real y aparente de 2700 y 1470 kg/m3 respectivamente, peso específico de 2240 kg/m3, porosidad de 62 %, absorción de 15.20 %, solubilidad en ácido clorhídrico de 29.96 %, pH de 7.4 y conductividad eléctrica de 70 mS/cm. Al agua residual con las que se desarrollaron los tratamientos se le aplicó previo al experimento un tratamiento primario (rejilla, desarenador, desnatador y fosa séptica) y presentó valores (promedio, N = 9) de temperatura de 25.26 °C, pH de 8.63, sólidos disueltos totales con 950.50 mg/L, color de 1305.10 UC, turbiedad 96.37 UNT y demanda química de oxígeno de 373 mg/L. De las zeolitas evaluadas (N = 81) en el BLFFA, la que presentó el mejor tratamiento fue la zeolita de cerro operando con una altura de lecho de 0.9 m y con 24 horas de tiempo de retención hidráulica; obtuvo las mejores eficiencias de remoción con 71.42 % en sólidos disueltos totales, 84.34 % para turbiedad, 96.33 % para color y 97.28 % para la demanda química de oxígeno. La altura óptima en los BLFFA fue 0.9 m, factor importante de evaluar, ya que a mayor altura se aumentan los costos y las eficiencias no son relevantes para justificar la inversión y a menor altura cae el rendimiento en calidad del agua tratada. En conclusión, las zeolitas nativas cuentan con propiedades idóneas para ser utilizadas en el tratamiento de agua residual doméstica y podemos recomendar la implementación de los BLFFA en el tratamiento secundario de efluentes domésticos en sistemas descentralizados del sureste de México como una alternativa viable en el tratamiento de sus aguas residuales domésticas.

Se evaluó el aprovechamiento de los subproductos cítricos mediante la fermentación de la corteza de naranja por medio de Aspergillus niger van Tieghem, 1867, el que fue obtenido por inoculación en placa Petri, a temperatura de 35°C y a un pH de 4,3. Se utilizó como substrato la corteza de naranja triturada, parcialmente deshidratada, extendida en bandejas, secada en bandejas de cartón y sin pretratamiento térmico, añadiéndole, únicamente, componentes y nutrientes minerales, y se cultivó a A. niger a diferentes temperaturas de fermentación entre 8°C y 40°C. Al culminar el proceso fermentativo de la corteza de naranja pretratada se obtuvieron porcentajes máximos de transformación de nitrógeno mineral a nitrógeno orgánico de 34,5 %, para un valor de la integral térmica entre 0°C y 320°C por día, obteniendo para un kg de materia seca, 6,6 % de proteína para 600 g de producto (pienso) con 18 % de proteína. Finalmente, se correlacionó la variación del pH del sustrato en función de la integral térmica del cultivo; el rendimiento de la transformación del nitrógeno mineral a orgánico en función de la integral térmica del cultivo y la evolución del contenido de nitrógeno orgánico del sustrato de naranja fermentado por el A. niger frente a la integral térmica. Los resultados muestran altos coeficientes de correlación. Se concluye que es posible aprovechar los subproductos cítricos mediante la fermentación de la corteza de naranja por A. niger.

Authors: Oliva Mario , Rimachi Segundo 
Published: April 2021

<p><em>Alnus acuminata </em>H.B.K, comúnmente llamado “aliso”, es una de las especies de mayor importancia por su rápido crecimiento, su utilización en sistemas agrosilvo-pastoriles, agroforestales, aporte de nitrógeno al suelo y madera comercial en el mercado regional. En la presente investigación se presenta una metodología para el proceso de enraizamiento para la generación de plantones clonales a mayor escala comercial de esta especie. El objetivo de estudio fue evaluar el porcentaje de enraizamiento de estaquillas utilizando brotes juveniles de 20 cm de longitud y 1 cm de área foliar (se utilizó la parte media y apical), bajo el efecto de tres dosis de ácido indol 3 – butírico (2000, 4000 y 6000 ppm), y tiempo de enraizamiento utilizando microtuneles como estructura de protección. El estudio se realizó en el vivero forestal de la Asociación de Productores Conservacionistas de Molinopampa, ubicado en el anexo de Espadilla. Se utilizó un diseño completamente al azar (DCA), con un arreglo factorial de 2A X 3B, con seis tratamientos y cinco repeticiones por tratamiento. Al término de 66,23 días en promedio, las estaquillas con dosis de 4000 ppm mostraron enraizamientos de 70,0% teniendo como sustrato tierra agrícola, humus de lombriz y arena de río en proporción 2:1:1. Se concluye que si es posible propagar <em>Alnus acuminata</em> (70,0% de enraizamiento), si se utiliza la dosis adecuada de AIB en estaquillas con tres folios.</p>
