Research progress of stem cell-derived exosomes in injury repair
Authors: Cui Fengrui , Li Fang , Zhang Tiening , Li Quan 
Published: April 2022

After organ and tissue injury, the proliferation and differentiation of stem cells themselves play only a small role in the repair of injury, and their repair role is mainly played through the paracrine function of stem cells. Exosomes are nano-scale vesicles that are secreted into the extracellular space in an exocytic manner, and its own function will be regulated after the target cells absorb the exosomes. Stem cell-derived exosomes communicate between cells by transmitting proteins, lipids and micro-RNAs (miRNAs). The targeting and biological properties of stem cell-derived exosomes are determined by the level of miRNAs that they carry. After the exosomes reach the target cells and undergo fusion, the gene expression of the target cells is changed by degradation and expression. In addition, the RNA and protein of stem cell-derived exosomes can also limit the development of injury through cell homing. This article will review the mechanism of stem cell-derived exosomes in wound healing, joint injury, fracture healing and cardiac injury.

Published: April 2022

In clinical practice, it may be difficult to differentiate brachial plexus schwannoma from pathological lymph nodes. Schwannoma is a relatively rare neoplasm arising from Schwann cells of the peripheral nerve sheath. Although it can occur in any organ, including the extremities, trunk, and head, it rarely presents as an axillary or supraclavicular lesion. In this the article, a 59-year-old male patient with painless swelling in the right supraclavicular fossa and cystic lymphadenopathy reported on USG is presented.
Quo Vadis, Crowdsourcing and Online Collaborative Translation?
Authors: Jiménez-Crespo Miguel 
Published: April 2022

Online collaborative translation experienced a meteoric rise in the e first decade of the 20th century thanks to the affordances provided by the Web 2.0. Two distinct models emerged, solicited and unsolicited models. In the first one a company or institutions request the help of volunteer or participants with translation tasks. In unsolicited models, fans, activists or different collectives self-organize to start a translation initiative. These practices quickly attracted the attention of the Language Industry after large corporations implemented crowdsourcing models (Google, Facebook or Twitter). Translation providers and tech companies explored collaborative initiatives in a context of exciting possibilities for growth, while it quickly became a serious cause for concern for professional translators and professional associations such as the International Federation of Translators (FIT) or the American Translators’ Association (ATA). As a rapidly growing phenomenon, Translation Studies scholars were quickly drawn to research this emerging set of phenomena. Initially, the main issues that appeared on Translation Studies literature were related to motivation, epistemological/ conceptual research, ethics, translator visibility, or the description of existing initiatives. The second decade of the 20th century saw the consolidation of these activities through technological developments and innovative workflows and the expansion to non-profit ventures, while new technology-driven models based on collaborative micro-task approaches emerged, such as “paid crowdsourcing”. By 2020, the number of providers offering translations crowdsourcing has been dramatically reduced. Many start-ups have been absorbed or have disappeared, while non-for-profit models of translation collaboration, such as educational, NGO or activist initiatives continue to grow. This paper offers a critical analysis of the evolution of translation collaboration on the web and potential future directions, as well as a review of existing research trends within Translation Studies. The paper ends with an exploration of potential future research trends and directions in this ever-changing area driven by technological innovation.

Published: April 2022

Aims: This study aimed to explore the effect of training set diversity on the performance of deep learning models for predicting early gastric cancer (EGC) under endoscopy.
Methods: Images of EGC and non-cancerous lesions under narrow-band imaging (ME-NBI) and magnifying blue laser imaging (ME-BLI) were retrospectively collected. Training set 1 was composed of 150 non-cancerous and 309 EGC ME-NBI images, training set 2 was composed of 1505 non-cancerous and 309 EGC ME-BLI images, and training set 3 was the combination of training set 1 and 2. Test set 1 was composed of 376 non-cancerous and 1052 EGC ME-NBI images, test set 2 consisted of 529 non-cancerous and 71 EGC ME-BLI images, and test set 3 was the combination of test set 1 and test set 2. Three deep learning models, convolutional neural network (CNN) 1, CNN 2 and CNN 3 (CNN 1, CNN 2 and CNN 3 were independently trained using training set 1, training set 2 and training set 3, respectively), were constructed, and their performances on each test set were respectively evaluated. One hundred and thirty-eight ME-NBI videos and 17 ME-BLI videos were further collected to evaluate and compare the performance of each model in real time.
Results: On the whole, the performance of CNN 3 was the best. The accuracy (Acc), sensitivity (Sn), specificity (Sp) and area under the curve (AUC) of test set 1 in CNN 3 were 87.89% (1255/1428), 90.96% (342/376), 86.79% (913/1052) and 94.60%, respectively. The Acc, Sn, Sp and AUC of test set 2 in CNN 3 were 95% (570/600), 97.92% (518/529), 73.24% (52/71) and 90.93% respectively. The Acc, Sn, Sp and AUC of test set 3 in CNN 3 were 89.99% (1825/2028), 95.03% (860/905), 85.93% (965/1123) and 94.89%, respectively. The performance of CNN 3 was also the best in videos test set. The Acc, Sn and Sp of videos test set in CNN 3 were 91.03% (142/156), 90.58% (125/138) and 94.44% (17/18), respectively.
Conclusions: The deep learning model with the most diverse training data has the best diagnostic effect.

The Magallanes region in Chilean Patagonia encompasses 13 million hectares with approximately 3.6 million used for agricultural and livestock systems. This portion is located to the east of the Andean Mountain chain in the rain shadow zone, with annual precipitation increasing along an east to west gradient from 200 to almost 1,000 mm. To fully describe sheep farming in the Magallanes region, many topics need to be addressed, including sheep production and management, existing vegetative communities, livestock-wildlife interactions, and economic diversification into agritourism and another sheep industry products. All these give shape to the story of the development of sheep farming in Magallanes, which is important at the regional and national level. Three key points are identified that together can lead to a successful future for the industry: sustainable management, human resources and the market.

Investigation of Pharmaceutical Care Practice in Two Tertiary Health Care Facilities in Central Monrovia, Liberia
Authors: Sampson K. P. CHEA, , Eric Woode, 
Published: April 2022

Aims: to identify elements of pharmaceutical care and to what extend it is practiced in these hospitals and to identify any drug-related therapeutic problems and determine the perceived importance of pharmaceutical care.
Study Design: A prospective, cross-sectional descriptive survey was carried out among hospital pharmacists and some selected physicians and physician assistants working at two major tertiary healthcare facilities in Liberia.
Place and Duration of Study: John F. Kennedy Memorial Hospital, and Eternal Love Winning Africa Hospital, between August, 2021 and October, 2021.
Methodology: Pretested structured questionnaires covering demographics and the key elements of pharmaceutical care documentation was administered randomly to 43 health professionals in these hospitals and collected for compilations and analysis.
Results: Twenty percent (20.9%) confirmed the documentation of pharmaceutical care elements in both facilities, and 18.6% confirmed the documentations of interventions. Methods used in documentation are paper (13.9%), manual (72.1%) and computers (6.9%) respectively. Unnecessary drug therapy/unwanted indication, adverse drug reactions, drug interactions, need for additional drugs, dosage too high, dosage too low, wrong drugs, and inappropriate compliance are the drug therapy problems that exist at both facilities. The overall percentage of all the drug therapy problems is twenty-five percent (25.6%), of which most are highlighted at John F. Kennedy Memorial Hospital, though these problems exist at both hospitals. There is an increase in drug therapy problems and a decrease in standard documentation format and method used to document pharmaceutical care at both hospitals. Thirty-nine percent (39.5 %) of the respondents recognized the importance of the documentation of pharmaceutical care (PC).
Conclusion: The study findings revealed that there is semblance of elements of pharmaceutical care activities at the both hospitals, but it is limited. Inadequate documentations of PC interventions coupled with primitive methods of recording PC data are highlighted by respondents. The practice of pharmaceutical care in the Liberia’s healthcare system can greatly improve the quality of pharmaceutical services and enhance the quality of life and therapeutic outcomes to patients/clients.

Published: April 2022

Increasing land-use pressure and monoculture coupled with inadequate restorative practices pose threat to sustainability, nutrient uptake of crops often exceeds replenishment causing fertility deterioration. Imbalanced and indiscriminate use of fertilizers deteriorates soil health and factor productivity. Long-term impacts on soil nutrient stocks influence the sustainability of crop production are major gains of regular inclusions of legume in a cropping system. Inclusion of green gram in potato cultivation increased organic carbon and nutrients than non-legume based potato cropping systems. Legume-based cropping systems increased soil C and N stock than only cereal based cropping system. Maize intercropped with velvet-bean recorded higher productivity compared with pure maize and pure maize with mineral fertilizers. Bulk density of soil in glyricidia + maize system was lower compared to sole maize and maize grass fallow. Intercropping with glyricidia, glyricidia pruning incorporated into the soil optimized the cation exchange capacity in soil than sole maize system. Higher grain yield of finger millet and sustainable yield index were observed in green leaf manuring. Due to socioeconomic and environmental benefits, legumes could be introduced in cropping systems to reduce external inputs and increase crop diversity. They also found to perform well in conservation systems, intercropping systems, which are very important in developing nations. Legumes fix nitrogen from the atmosphere and aid in the cycle of soil nutrients and water retention. Because of their many uses, legumes have a lot of potential for conservation agriculture, as they can be used as a growing crop or as crop residue.

Authors: Pradeep Rajasri , Krishnan Reshma Poothakulath 
Published: April 2022

Background: Stem cells, the hero of regenerative medicine, are self renewable and has the potential to regenerate. Dental stem cells have proven to be an excellent source for mesenchymal cells. Dental mesenchymal cells can be applied for the replacement of dental and oral tissues against various tissue-damaging conditions including dental caries and periodontitis as well as for systemic regulation of excessive inflammation in immune disorders, such as autoimmune diseases and hypersensitivity. In this study, a survey was conducted among the dental students of a private dental hospital regarding their awareness about stem cell therapy used in dentistry.
Materials and Methods: The study was conducted with the help of a questionnaire which was circulated with the help of social media and the internet. The target population were the dental practitioners and students of Saveetha Dental College. The questionnaire consisted of 15 questions that tested their knowledge and awareness regarding stem cell therapy in dentistry.
Results: A majority of the undergraduate dental students were aware of basics in stem cell therapy in dentistry. The majority were willing to practice regenerative therapy in future or invest for the same in one way or the other. The overall response of and the percent analysis were calculated for each question.
Conclusion: It can be concluded that the dental students of Saveetha dental college have sufficient knowledge and awareness regarding dental stem cells. Practice of dental stem cell therapy may be a big step now but is definitely going to be an advantage in the future.
Bangkok Street Food Vendors (SME) Business Continuity during COVID-19 Pandemic
Authors: Gruenwald Hermann 
Published: April 2022

Aims: This study aimed at capturing the perceptions of Bangkok street food vendors related to the business continuity of SMEs during the covid-19 pandemic.
Study Design: The study design followed the 7 Ps of the service marketing model: product, price, place, promotion, process, physical evidence, and people related to street food.
Place and Duration of Study: The study took place in Bangkok, Thailand from Summer 2021 until Fall of 2021.
Methodology: We included 200 participants (66 men, 124 women; age range 18-80 years) who were SME street food vendors, 40% of them were under 40 years old with 59% having no university education and 35% with a bachelor degree. Two-thirds of the vendors (86%) earned less than 500 USD a month.
Results: In terms of product the vendors stuck to the favorites (mean 4.34 and SD 0.97) trying to maintain quality and quantity while keeping prices constant as much as possible (mean 4.35 and SD 0.89). The most effective promotion was the 50/50 government food substitute co-payment (mean 4.69 and SD 0.99). Place changed from sit-down restaurants to take-away (mean of 4.77 and SD 0.96) and home delivery via food delivery apps (FDA). Process changes due to social distancing included screens and fewer tables (mean of 4.51 and SD 0.65) The number one physical evidence was wearing face masks and sanitization (mean 4.03 and SD 0.82). People changed in terms of customer mix with fewer foreigners and local tourists (mean of 4.77 and SD 0.75) as well as fewer migrant workers and more government agents taking a closer look at street food hawkers.
Conclusion: Street food hawkers adjusted all 7Ps of the marketing mix to assure business continuity during the covid-19 pandemic as discussed above. Moving to food delivery along with face masks and social distancing were the biggest changes. These predictors, however, would benefit from further work to validate reliability in Thailand, ASEAN, and worldwide.
IBLF‐based event‐triggered adaptive learning control of nonlinear systems with full state constraints
Authors: Jiang Xiao‐Yue , Li Yuan‐Xin 
Published: April 2022

SummaryThis article focuses on the adaptive asymptotic learning tracking control problem of nonlinear systems with full state constraints. First, an adaptive neural network tracking algorithm is proposed which combines a time‐varying feedback element and robust compensation feedback element in the form of smooth function to guarantee that output signal tracks the reference signal asymptotically. Apart from this, a time‐varying integral barrier Lyapunov function is utilized to ensure that the system states are always kept in the constraint region. Furthermore, the event‐triggered mechanism is designed to efficiently reduce unnecessary transmissions. Compared with the other literatures, the original state constraint problem is directly solved by the proposed adaptive control algorithm. Finally, simulation is included to validate the built theoretical results.
Scalable Reflective Plasmonic Structural Colors from Nanoparticles and Cavity Resonances – the Cyan‐Magenta‐Yellow Approach
Authors: Blake Jolie C. , Rossi Stefano , Jonsson Magnus P. , Dahlin Andreas 
Published: April 2022

AbstractPlasmonic metasurfaces for color generation are emerging as important components for next generation display devices. Fabricating bright plasmonic colors economically and via easily scalable methods, however, remains difficult. Here, the authors demonstrate an efficient and scalable strategy based on colloidal lithography to fabricate silver‐based reflective metal–insulator–nanodisk plasmonic cavities that provide a cyan‐magenta‐yellow (CMY) color palette with high relative luminance. With the same basic structure, they exploit different mechanisms to efficiently produce a complete subtractive color palette. Finite‐difference time‐domain simulations reveal that these mechanisms include gap surface plasmon modes for thin insulators and hybridized modes between disk plasmons and Fabry–Pérot modes for thicker systems. To produce yellow hues, they take advantage of higher‐energy gap surface plasmon modes to allow resonance dips in the blue spectral region for comparably large nanodisks, thereby circumventing difficult fabrication of nanodisks less than 80 nm. It is anticipated that incorporation of these strategies can reduce fabrication constraints, produce bright saturated colors, and expedite large‐scale production.
