Authors: Silva Danillo De Almeida e , Melo Carlos Eduardo Luna de
Published: September 2021

O presente artigo consiste em uma revisão bibliográfica que busca referenciar o uso do resíduo de construção e demolição (RCD) como uma viável e crescente alternativa, tornando-se uma solução para a grande demanda de recursos naturais utilizados na construção civil. Os critérios elaborados para este estudo tiveram como foco o uso do agregado reciclado e seu teor de substituição no concreto, juntamente com os mecanismos relacionados à sua qualidade. A reciclagem do RCD e o uso em concreto é objeto de pesquisas em vários países, visando uma destinação sustentável para o resíduo gerado na construção civil. Essas pesquisas têm apresentado resultados satisfatórios no uso do agregado reciclado para concreto estrutural e não estrutural, e os resultados apresentam uma possível faixa de substituição do agregado natural. Dessa forma, o uso do RCD como material alternativo para produção de concretos e materiais construtivos vem apresentando inúmeros benefícios para a economia, meio ambiente e sustentabilidade da construção civil. Essa tecnologia vem criando produtos a partir de resíduos da construção, evitando a extração de matérias-primas e preservando o meio ambiente.

Published: September 2021

Os serviços de conservação são fundamentais para a garantia do desempenho das rodovias. Nesta pesquisa foi realizada uma análise do estado de conservação da rodovia PB-293 para identificar as manifestações patológicas encontradas e sugerir soluções para as mesmas. Ainda, foi definido um trecho de 1,0 km da rodovia e propôs-se dois tipos de pavimentação, sendo uma flexível em tratamento superficial duplo e outra rígida de concreto. A metodologia utilizada para a elaboração dos custos estimativos dos serviços de implantação, conservação e recuperação foi auxiliada pelo simulador online de custos médios gerenciais do Instituto Brasileiro de Economia (IBRE) da Fundação Getúlio Vargas e do Sistema de Custos Referenciais de Obras (SICRO) do DNIT. Com o levantamento, observou-se que o pavimento flexível, na análise de 20 anos, apresentou uma diferença de R$ 277.013,82, ou seja, 27,26% a menos que o pavimento rígido proposto. Já, na análise de 40 anos, os dois pavimentos apresentaram quantitativo de custos estimativos muito próximos, com uma diferença de R$ 24.962,36, correspondente a 1,47% a mais para o pavimento flexível, neste caso. Vale ressaltar que, além dos custos, outros fatores devem ser levados em conta no planejamento de conservação e recuperação de uma rodovia.

Published: September 2021

Background: We aimed to investigate the potential effects of BCG and imiquimod on improvement of current experimental L. major vaccine against dogs in an endemic area of Zoonotic visceral leishmaniasis (ZVL) in Iran.
Methods: During 2012 till 2014, seven mixedbreed shepherd dogs with no anti-Leishmania antibodies and no response to Leishmanin reagent were immunized with 2 doses of alum-precipitated autoclaved L. major (Alum-AML) while BCG and imiquimod (for skin pre-treatment) were used as adjuvants. The productions of a few characteristic cytokines of T-helper immune responses and the development of delayed-type hypersensitivity (DTH) of the immunized animals were then evaluated, up to 300 days. Blood samples were collected at 0, 30, 80 and 300 d post-vaccination and the concentrations of IFN-γ, IL10, IL-12 and TGF-β cytokines secreted from PBMCs at these time-points were quantified by ELISA. DTH was evaluated by Leishmanin skin test (LST).
Results: Although a similar LST conversion was observed at all time-points, the cytokine measurement results indicated significantly higher levels of IFN-γ at day 80 and elevated levels of IL-10 at days 80 and 300, post-vaccination. Moreover, a significantly higher IFN-γ/IL-10 ratio was observed at day 30 post-vaccination compared to the other time-points.
Conclusion: Although a Th1-like response could be observed at day 30 post-vaccination, the development of cytokine profiles was inclined toward mixed Th1 and Th2 responses at days 80 and 300 post-vaccination. This situation may indicate the requirement of an additional boosting by this Alum-AML formula, in order to induce long-lasting protection against ZVL.

Published: September 2021

Background: Cystic Echinococcosis (CE) is an emergent or re-emergent zoonosis and remains a public health and economic problem all over the world.
Methods:  The present study was carried on the prevalence and genotypes of Echinococcus present in small ruminants in Kashmir valley. A total of 2100, sheep (2052) and goats (48), slaughtered or spontaneously dead, from various areas of Kashmir valley were screened for the presence of hydatidosis. In case of goat none of the cases were found positive for hydatidosis, whereas, all the positive cases (85) were recorded in sheep only. The overall prevalence of hydatidosis was 4.04%. The prevalence was higher in female sheep (5.46%) compared to males (2.83%). Season-wise highest prevalence was in summer (4.55%), followed by autumn (4.1%), spring (3.89%) and winter (2.5%).The liver was observed to be the most frequently infected organ with relative prevalence of 61.17% followed by lungs (38.82%).The rDNA-ITS1 fragment of positive samples was amplified with BD1 / 4S primers.
Results: The length of amplified fragment for all isolated samples was 1000bps. The products obtained on PCR were digested with four restriction enzymes (Rsa 1, Alu 1, Msp 1 and Taq1). Rsa 1, Alu 1, Msp 1 yielded identical fragments, 300 and 700 bp in sheep. TaqI restriction enzyme had no effect on PCR product and after digestion; intact 1000bps fragment was seen.
Conclusion: Phylogenetic analysis of ITS1 gene revealed that the common sheep strain (G1) is the predominant genotype in sheep in Kashmir valley.

Published: September 2021

Background: We aimed to determine whether neutralizing high mobility group box-1 (HMGB-1) prevents the release of HMGB-1 and proinflammatory cytokines on hemozoin (Hz)-induced alveolar epithelial cell in a model of malaria associated ALI/ARDS.
Methods: This study was conducted in the Department of Tropical Pathology, Faculty of Tropical Medicine, Mahidol University, Bangkok, Thailand in 2020. Human pulmonary alveolar epithelial cells (HPAEpiCs) were exposed to medium alone or 20 µM Hz for 24 h and incubated with different concentrations (1, 5, and 10 µg/ml) of anti-HMGB-1 monoclonal antibody (mAb) for various times (0, 4, 12, 24, and 48 h). The levels of HMGB-1, TNF-α and IFN-γ in the supernatants were measured by ELISA. The mRNA expression of RAGE, TLR-2 and TLR-4 were analyzed by real-time PCR.
Results: The HPAEpiCs treated with 10 µg/ml anti-HMGB-1 mAb showed a significant reduction in HMGB-1 release into the supernatant compared with those treated with 1 and 5 µg/ml anti-HMGB-1 mAb. The levels of TNF-α and IFN-γ were significantly decreased in the supernatant of HPAEpiCs treated with 1, 5, and 10 µg/ml anti-HMGB-1 mAb for 4, 12, 24, and 48 h compared with those stimulated with Hz alone. The mRNA expression levels of RAGE, TLR-2, and TLR-4 were significantly decreased after 24 h of anti-HMGB-1 antibody treatment at all concentrations.
Conclusions: An anti-HMGB-1 antibody could be an effective agent for inhibiting the release of HMGB-1, TNF-α and IFN-γ. Furthermore, a neutralizing anti-HMGB-1 antibody could be applicable for the treatment of malaria-associated ALI/ARDS.

Authors: Othman Rateb A. , Abuseir Sameh
Published: September 2021

Background: Dogs play an important role in transmission of parasites and zoonotic diseases, especially in developing countries. We aimed to investigate the prevalence of internal parasites in stray and pet dogs in Palestine.
Methods: Fecal samples were collected during the period between Jan to May 2019. A total of 150 fecal samples were collected and tested for parasites using sedimentation and flotation techniques. The targeted dogs were both pet dogs and stray dogs and were grouped according to gender and age.
Results: Although there was no significant difference in infestation between males and females, the prevalence rate of infestation in males was 63.1% compared to females 72.4%. Dogs of ages under one year had similar rate of infestation compared to older dogs with a rate of 67.3% and 67.4% respectively. Infestations were significantly higher (P<0.05) in stray dogs 81.4% compared to pet dogs 48.4%. The highest infestation rate was with Toxocara canis 46.0% followed by Dipylidium caninum 23.0%, Echinococcus spp. 14.0% ,Isosopora canis  9.0%, Ancylostoma caninum 8.0%, Giarda spp. 5.0%, Strongyloides spp. 4.0%, Trichuris vulpis 3.0%, and Cryptosporidium spp. 3.0%.
Conclusion: Local dogs in Palestine, especially stray dogs, are infested with different types of intestinal parasites that may cause many common and non-common diseases to humans. To prevent the spread of these parasites, future public health should be proposed and applied by authorities to achieve a healthy status of the residents in the country. Health awareness spread among people about the seriousness of the diseases transmitted by dogs must also be activated.

Authors: Guo Yue , Dong Hai Yan , Zhou Hong Chang , Zhang Zhong Shan , Zhao Yu , Zhang Yu Jie
Published: September 2021

Background: Multicellular parasites Angiostrogylus cantonensis larvae develop in the final host rat brain at the fourth stage (L4) and migrate to the lungs by the adult stage. The potential mechanism of its blood-brain barrier (BBB) passage remains unclear.
Methods: By using Illumina Hiseq/Miseq sequencing, we obtained the transcriptomes of 3 groups of adult males and 3 groups of female of A. cantonensis to generate similarly expressed genes (SEGs) between 2 genders at the adult stage. Next 2 groups of L4 expressed genes were used to compared with SEGs to create differentially expressed genes (DEGs) between 2 life stages to unlock potential mechanism of BBB passage.
Results: In total, we obtained 381 581 802 clean reads and 56 990 699 010 clean bases. Of these, 331 803 unigenes and 482 056 transcripts were successfully annotated. A total of 3 166 DEGs between L4 and adults SEGs were detected. Annotation of these DEGs showed 167 were down-regulated and 181 were up-regulated. Pathway analysis exhibited that calcium signaling pathway, the ECM−receptor interaction, focal adhesion, and cysteine and methionine metabolism were highly associated with DEGs. The function of these pathways might be related to BBB traversal, as well as neuro-regulation, interactions between parasite and host, environmental adaption.
Conclusion: This study expanded the regulatory characteristics of the two important life stages of A. cantonensis. This information may provide a better appreciation of the biological features of the stages of the parasitic A. cantonensis.

Published: September 2021

Background: Opisthorchis viverrini is one of the endemic helminths in Thailand. Nonetheless, O. viverrini still exist and raise concerns regarding public health. This study aimed to evaluate the current prevalence of O. viverrini infections and underlying risk factors among rural communities in Northeast Thailand.
Methods: A cross-sectional study was conducted between Sep and Dec 2019 in Phon Sawan district in Nakhon Phanom Province, Thailand. The participants were selected using a voluntary sampling method after the proportional allocation of the total sample size. Demographic data were collected using a standardized questionnaire. One stool sample was collected from each participant and the presence of O. viverrini and other intestinal parasite infections were determined using the modified Kato-Katz technique.
Results: Overall, 250 participants aged 21 yr or older were enrolled. Overall, the prevalence of O. viverrini and Strongyloides stercoralis was 24% (95% confidence interval [CI]: 18.8-29.8) and 1.2% (95% CI: 0.2-3.5), respectively. Of the positive O. viverrini cases, the parasite rate significantly differed between gender, age group and in those who had a history of eating raw fish and taking the anti-helminthic drug (all P<0.05). Nevertheless, multivariate regression analysis among O. viverrini cases revealed that only being male (adjusted odds ratio [aOR] 1.9 [95% CI: 1.1 – 3.6], P = 0.033) and aged ≥61 yr (aOR 6.7 [95% CI: 1.4 – 32.5], P=0.018) were positively associated with a higher risk of O. viverrini infection.
Conclusion: Opisthorchiasis and strongyloidiasis are still endemic in this area and there is a need for projects to eliminate these parasites.

Authors: Seo Byung-Ro , Kim Kyoung-Lee
Published: September 2021

The significant impacts of recent infectious diseases (MERS, COVID-19) demand fundamental changes and alternatives in different markets, such as tourism and the medical tourism industry. In this study, we aimed to have a historical investigation on how infectious diseases have affected the tourism industry in Korea, to reach practical implications for managing the medical tourism sector. The impact of global infectious diseases, including MERS, and COVID-19, on the tourism industry was studied in South Korea. First, the available information was collected to clarify how these two outbreaks have impacted the tourism market in South Korea, and then the government's countermeasures were studied. Investigating among the policies resulted in practical implications for the post-pandemic revitalizing plan for the medical tourism market. The infectious outbreak caused a significant decrease in the number of inbound tourists to South Korea, moreover, the crisis response system of the government has been useful so far. Hence, several practical implications can be achieved for the medical tourism market. A framework is suggested which involves 5 stages of strategies to revitalize medical tourism market. It presents remedies to revitalize the medical tourism industry and to enter the global market again. Korea's quarantine model, which succeeded in preventing COVID-19, can be a preemptive response to another pandemic in the future. The medical tourism industry policy based on Korea's quarantine model will contribute to the revitalization of the international medical tourism industry after COVID-19.

The global campaign of osteoporosis has been organized by the International Osteoporosis Foundation (IOF) and them introducing World Osteoporosis Day (WOD) in 1997. The day is celebrated on October 20th each year and aimed to improve the awareness of the population about disease prevention. We present some aspects of bone health and the prevention of osteoporosis related to the use of vitamins. The presenting mini-review covers a variety of sources including PubMed, Embase, Scopus, and directory of open access journals (DOAJ) from 10 years ago (Oct 2009 to Oct 2019) for recent developments in the prevention of bone loss. The search was performed by using combinations of the following keywords and or their equivalents; osteoporosis, bones health, bone loss, and vitamin to find related articles about the prevention of osteoporosis by nutritional factors. The factors affecting   bone are various and could begin from fetal periods to the end of life. Some of them are not changeable including age, and genetic; however, it is possible to modify some others such as poor nutrition and vitamin deficiency. Beyond vitamin D deficiency, consumption of other vitamins also is beneficial to maintain bone health. By considering the nutritional factors especially vitamins that affect bones, it is possible to have stronger bones to enjoy life in the elderly and protect your future.

Authors: Lü Hui , Zhang Huaning , Liu Ting , Hao Wei , Yuan Qun
Published: September 2021

Background: Vibrio cholerae is an important bacterium causing profuse watery diarrhea. Cholera had swept the whole Shandong province from 1975 to 2013.
Methods: From epidemiological data and pulsed-ﬁeld gel electrophoresis data, we selected 86 V. cholerae isolates appearing in Shandong Province in China from 1975 to 2013 and characterized them by multilocus sequence typing (MLST)/multi-virulence locus sequence typing (MVLST), antibiogram and analysis of genes related to antibiotic resistance.
Results: Combined MLST/MVLST data revealed 33 sequence types and a major group. Within the group, 3 subgroups (ST1, ST24 and ST29) were revealed, prevalent in the strains isolated during the 1980s, 1990s and 21st century, respectively. All the O1 isolates after 1990 were found to be El Tor variants harboring the classical ctxB gene. The tcpA gene of O139 strains had a mutation at amino acid position 62 (N→D). Antibiotic resistance of V. cholerae increased over time. Most El Tor variants between 1998 and 1999 were resistant to trimethoprim/sulfamethoxazole. The O139 strain, since its appearance in 1997, had significantly broader spectrum of antibiotic resistance than O1 variants. The presence of the SXT element corresponds to the trend of growing drug resistance.
Conclusion: The analysis of genotypic polymorphism and enhanced resistance of V. cholerae indicated continuous variation and evolution of this pathogenic agent in Shandong Province.

The article presents structural diagrams of an automated control system for technological processes and information flows of logging operations. The article includes subject and research methodology. The study in a field of logging operations confirms the fact of increasing rate of using special forest machinery like forest harvesters for conducting timber-logging operations. One of the main advantages of forest harvesters is the automated functions that allow the control system to optimize the cutting of the tree trunk, taking into account the price of the assortment and its optimal parameters. The majority of forest harvesters in service are equipped with a continuous pull-through harvesting head. It is shown that reducing production and resource losses, preserving the natural environment and adequate measures for the reproduction of wood resources becomes possible due to the transfer of management of forestry processes to a qualitatively new level through the use of modern automated control systems for technological processes and information flows (APCS IP). The development of a software decision support system (DSS) was conducted according to the results of the data process analysis. The automated decision support system provides support for operator activities and a model for making a decision on the appointment and execution of timber-logging operations.

The results of molecular-genetic studies of populations of oak petiolate from 11 regions of Russia are presented. Using 10 microsatellite primers, 1049 alleles were identified. The studied samples differ insignificantly in the observed and effective number of alleles. To assess the genetic variability of populations, an indicator of expected and observed heterozygosity was calculated, which indicates a deficiency of heterozygous genotypes. It was found that each individual tree in the studied populations shows 87 % deficiency of heterozygotes relative to the population and 85,7 % relative to the species. It was noted that among all the studied alleles, 81 % were unique, and they occur only in one locus. The dendrogram based on the genetic distance shows clustering of the populations of the oak petiolate into several separate groups.

Reaching Out: A Publication Trend Analysis of Scholarly Articles Discussing Graphic Novels and Reluctant or Struggling Readers
Authors: Kirkham Mary
Published: September 2021

Graphic novels combine short text and pictures to tell a story or convey information while still engaging the reader visually. This is a potentially useful tool for reaching out to struggling and reluctant readers. Struggling readers have difficulty reading and understanding what it is they are reading. Pictures allow for more context clues than just text alone, allowing for the potential for greater success in comprehension for struggling readers. Reluctant readers, on the other hand, may have more of a distaste for reading. In some cases, they are capable of understanding what they read, but they do not enjoy the activity and tend to avoid it. Graphic novels allow for a more visual experience when reading and potentially grabbing and holding the reluctant readers' interest. The purpose of this study is to analyze the publication trends in library and information (LIS) journal articles as well as educational journal articles that discuss graphic novels and reluctant or struggling readers, specifically publication trend over time, authorship, core journals, and the number of articles that are based on surveys or interviews.
Locating Banned Books: A Collection Analysis of Libraries in Arkansas and Tennessee
Authors: Thomas Floyce
Published: September 2021

No library can make everything available to its patrons. However, libraries should adhere to the American Library Association (ALA) for guidance on what items are banned from the library's collections. Censorship and intellectual freedom have gained attention for how it affects libraries and the restraints it individualized for banned or forbidden items. Difficulties are characterized as formal, composed complaints recorded with a library or school asking for specific materials to be expelled from view because the substance may not be considered appropriate for the users. The purpose of this study is to compare a selected set of previously banned books or challenged titles in the collections of twelve public libraries within two southern states: Arkansas and Tennessee. The titles include: I Know Why the Cage Birds Sings by Maya Angelou; Beloved by Toni Morrison; Bluest Eye by Toni Morrison; and The Color Purple by Alice Walker.
An investigation of occupational burnout levels of Turkish EFL teachers by various variables
Authors: Selma Deneme
Published: September 2021

This study aims to investigate the occupational burnout levels of Turkish EFL teachers by various variables. The general survey method was used in the study. The data were collected by creating a scale in the Google forms. The study group of the research consists of 365 EFL teachers working in the fall semester between January and March 2021.  In this study, the Teacher Burnout Scale developed by Kaner, Şekercioğlu, and Yellice (2008) was used. According to the results of the research, no significant relationship was found between the burnout levels of Turkish EFL teachers and the variables of gender, marital status, and economic level. On the other hand, it was seen that the variables of professional seniority, getting support from colleagues and administrators affected the burnout levels of  the teachers. The findings were discussed in relation to the literature and suggestions were made.

Women's Experiences of the Coping With Birth Trauma:A Psychoeducational Group Support Program
Authors: Roberts Nicola-Jade , Jomeen Julie , Thomson Gill
Published: September 2021

OBJECTIVE

Between 20%-50% of women experience birth as traumatic, with negative impacts for women, infants and families. Currently, there is a lack of evidence into supportive interventions to ameliorate women's adverse responses following a traumatic birth. In North-West UK, a 6-week psychoeducation group support program (Coping with Birth Trauma [CwBT]) was developed and delivered by two trained therapists. The course aimed to facilitate women's understanding of trauma, and to provide coping strategies; additional speakers were also invited to discuss specialist issues. The aim of this evaluation was to explore women's experiences and perceptions of the CwBT, and to identify recommendations for course development.

METHODS

Following university ethics approval, all the women who had attended a CwBT course (n = 3) were invited to take part in a telephone interview. Eight women out of a possible sample of 16 agreed to participate. Thematic analysis was used to analyse the interview data.

RESULTS

Two themes and associated sub-themes describe the social, cognitive and instrumentalcomponents of the CwBT course (“Creating a difference”) and how the course facilitated growth and help-seeking behaviors (“Growth and renewal”). The final theme “complaints and recommendations” details critical reflections and suggestions for course development. Recommendations included speakers from different therapeutic backgrounds and more opportunities for contact with women at different stages of their trauma journey.

CONCLUSIONS

Overall, the course was well received with positive implications for health, wellbeing and family functioning. Further and large-scale studies to assess its effectiveness are needed.

Authors: Andriani Christin , Gunawan Pricilla Yani
Published: September 2021

A primary headache is the most common neurological complaint and is experienced by almost everyone throughout life.  The most common type of primary headache is TTH (Tension-Type Headache) and Migraine. Quality of sleep is associated with life satisfaction and data shows that one-third of adults are affected by poor sleep. Many studies have mentioned that there is a relationship between quality of sleep and primary headache, but no study has ever been conducted in Siloam Hospital Karawaci. We did a case-control study in Siloam Hospital Karawaci using purposive sampling, with a total of 50 patients as the subjects. Data were collected using the PSQI questionnaire and DASS 42 between January 2019 – March 2019. It was found that there was a significant relationship between sleep quality and primary headache (p= <0,001).

Bu araştırmanın amacı, 2018 yılında yenilenen öğretim programları ile güncellenen ilkokul üçüncü ve dördüncü sınıf fen bilimleri ders kitaplarındaki etkinlikleri etkinlik tasarım prensipleri çerçevesinde incelemektir. Çalışmada üçüncü ve dördüncü sınıf fen bilimleri ders kitabında yer alan 58 etkinlik nitel araştırma yöntemlerinden doküman incelemesi yoluyla incelenmiştir. Etkinliklerin analizinde; amaç, zaman kullanımı, sınıf organizasyonu, öğrencilerin ön bilgilerine uygunluk, kapsayıcılık, kullanılan materyallerin uygunluğu, öğretmen ve öğrenci rolleri, öğrenci zorluğunu aşma, ölçme değerlendirme, esneklik ve uygulanabilirlik etkinlik tasarım prensipleri temele alınmış, bu prensiplerin alt boyutlarından en az birine yönelik olan etkinlikler ilgili prensibe uygun olarak değerlendirilmiştir. Etkinlikler betimsel analiz tekniği ile çözümlenmiştir. Araştırma sonucunda MEB üçüncü ve dördüncü sınıf fen bilimleri ders kitaplarındaki etkinliklerin büyük çoğunluğunun etkinlik tasarım prensiplerinin birçoğunu kapsar nitelikte tasarlandığı belirlenmiştir. Ancak etkinlik tasarımında özellikle zaman kullanımı ve öğretmen rolü prensipleri ile amaç ve öğrenci zorlukları prensiplerinin bazı ölçütlerinin ihmal edildiği tespit edilmiştir. Araştırmada ayrıca incelenen üçüncü sınıf ders kitaplarda yer alan etkinliklerin tamamının, dördüncü sınıf ders kitabında yer alan 34 etkinliğin 28’ inin uygulanabilirlik tasarım prensibine uygun olduğu belirlenmiştir.
Workflow to Investigate Subtle Differences in Wine Volatile Metabolome Induced by Different Root Systems and Irrigation Regimes
Authors: Awale Mani , Liu Connie , Kwasniewski Misha T.
Published: September 2021

To allow for a broad survey of subtle metabolic shifts in wine caused by rootstock and irrigation, an integrated metabolomics-based workflow followed by quantitation was developed. This workflow was particularly useful when applied to a poorly studied variety cv. Chambourcin. Allowing volatile metabolites that otherwise may have been missed with a targeted analysis to be included, this approach allowed deeper modeling of treatment differences which then could be used to identify important compounds. Wines produced on a per vine basis, over two years, were analyzed using SPME-GC-MS/MS. From the 382 and 221 features that differed significantly among rootstocks in 2017 and 2018 respectively, we tentatively identified 94 compounds by library search and retention index, with 22 confirmed and quantified using authentic standards. Own-rooted Chambourcin differed from other root-systems for multiple volatile compounds with fewer dif-ferences among grafted vines. For example, the average concentration of β-Damascenone present in own-rooted vines (9.49 µg/L) was significantly lower in other rootstocks (8.59 µg/L), whereas mean Linalool was significantly higher in 1103P rootstock compared to own-rooted. β-Damascenone was higher in regulated deficit irrigation (RDI) than other treatments. The workflow outlined not only was shown to be useful for scientific investigation, but also in creating a protocol for analysis that would ensure differences of interest to industry are not missed.
Selective Breeding for Disease Resistant PRNP Variants to Manage Chronic Wasting Disease in Farmed Whitetail Deer
Authors: Haley Nicholas , Donner Rozalyn , Merrett Kahla , Miller Matthew , Senior Kristen
Published: September 2021

Chronic wasting disease is a fatal transmissible spongiform encephalopathy (TSE) of cervids caused by a misfolded variant of the normal cellular prion protein, and is closely related to sheep scrapie. Variations in a host’s prion gene, PRNP, and its primary protein structure, dramatically affect susceptibility to specific prion disorders, and breeding for PRNP variants that prevent scrapie infection has led to steep declines in the disease in North American and European sheep. While resistant alleles have been identified in cervids, a PRNP variant that completely prevents CWD has not yet been identified. Thus, control of the disease in farmed herds traditionally relies on quarantine and depopulation. In CWD-endemic areas, depopulation of private herds becomes challenging to justify, leading to opportunities to manage the disease in situ. In the present study, we developed a selective breeding program for farmed white-tailed deer in a CWD-endemic area, focused on reducing frequencies of highly susceptible PRNP variants and introducing animals with less-susceptible variants into historically high prevalence areas. We found that breeding followed predictable Mendelian inheritance, and early data support our project’s utility in reducing CWD prevalence. This project represents a novel approach to CWD management, with future efforts building on these findings.
Bounds on the Number of Primes in Ramanujan Interval
Authors: Feliksiak Jan
Published: September 2021

The Ramanujan primes are the least positive integers Rn having the property that if m ≥ Rn, then πm − π(m/2) ≥ n. This document develops several bounds related to the Ramanujan primes, sharpening the currently known results. The theory presented is by no means exhaustive, however it provides insights for future research work. Alternatively, we may say that it is a road map which may be followed to make further discoveries.
Hydrogel-Based Delivery for Antineoplastic Drugs and Vascular Scaffolding

Published: September 2021

Hydrogels, hydrophilic polymeric compounds, have been recently put under investigation as regenerative medicine applications and delivery systems for antineoplastic drugs, particularly chemotherapeutics (anthracyclines, alkylating agents), target drugs (trastuzumab) and immunotherapies. Porosity, conductivity, biodegradability and physical states are some of the peculiarities that render hydrogels suitable for therapies implementation. Chemically-modifying agents and enzymes can be also coupled to hydrogels for pharmacokinetical parameters improvement and side effects avoidance. Cardiotoxicity is in fact one of the major issues for oncological patients after treatment efficacy. Heart failure, myocarditis and hypertension are causes of morbidity and mortality that can possibly be avoided. Specific reaching of the target tumor site has been achieved by several authors in preclinical in vivo studies but clinical studies are currently under design processes. Polydioxanone, a hydrogel-mimicking agent, is capable to interact with the elastic properties of pulmonary artery. An advantageous characteristic is that can be also reabsorbed within biological systems and can cause a remodeling process of the vessel wall. Hydrogels currently represent a strong topic of interest for researchers and probably will guide future clinical investigations and practice.
