O objetivo desta pesquisa foi avaliar possíveis adulterações por adição de açúcares ou dextrinas em méis comercializados no município de Duque de Caxias, Rio de Janeiro, além de realizar análise da conformidade de rotulagem. Para tal, foram utilizadas dez diferentes marcas analisadas em duplicatas, perfazendo o total de 20 amostras. Este estudo buscou detectar fraude por presença de amido e dextrinas, bem como verificar a adequação das informações expostas no rótulo. Foi utilizada a prova do Lugol, onde a presença de glicose comercial ou xarope de açúcar, provocou a alteração da coloração de marrom-avermelhada à azul. Os resultados foram positivos para fraude por adição de açúcares comerciais em ambas amostras duplicatas de duas marcas entre as analisadas. Em relação às análises de rotulagem, oito rótulos apresentavam descumprimento em pelo menos um parâmetro avaliado. Apenas duas das dez marcas analisadas apresentaram concordância com à legislação em sua integralidade. Portanto, torna-se necessária uma melhoria significativa na fiscalização sanitária destes alimentos, considerando, principalmente, que os mesmos possuem selo de inspeção.
Utilização de retalho axial omocervical após ressecção de sarcoma de tecidos moles grau I em canino: Relato de caso
Authors: Suder Amanda
Published: September 2022

Soft tissue sarcoma (STM) has a mesenchymal origin, occurring most commonly in middle-aged to elderly dogs. The aim of this paper is to report a case of a five-year-old female German Shepherd canine, unneutered, weighing 32kg, treated at the Veterinary Hospital of the University of Passo Fundo with a main complaint of increased submandibular volume. Cytological examination showed a malignant mesenchymal neoplasm, possibly a soft tissue sarcoma. The patient was referred for surgical removal of the neoplasm using an axial omocervical flap. Histopathological examination confirmed the diagnosis of Grade I soft tissue sarcoma. This neoplasm is considered malignant and the importance of performing a cytological examination for a presumptive diagnosis, as well as a histopathological examination for a definitive diagnosis, is emphasized, since the surgical procedure is curative.

Does Covid-19 Have any Impact on the Performance of Multi-Cap Funds in India? A Study with Reference to HDFC Equity Fund and Kotak Standard Multi-Cap Fund
Authors: Das Sourav Kumar , Das Samyabrata
Published: September 2022

The stupendous growth of Assets under Management (AUM) of Indian Mutual Fund Industry is evident from the fact that from meagre Rs. 25 crores in 1964 the AUM of the industry crossed Rs.23.93 lakh crores in April 2020. Multi-cap funds tend to invest in stocks of companies across the stock market irrespective of sector and size. As such, these funds provide the much-needed diversification. In a direct plan, the investor decides to invest directly in mutual funds without routing the investment through any distributor or agent. The direct plan has a lower expense ratio than a regular plan because of the absence of intermediary commission which leads to a higher return. However, the direct plan makes sense for knowledgeable, experienced and do-it-yourself (DIY) investors. Since the outbreak of COVID-19 in India, the global contagious disease caused by cronavirus in January 2020, the stock markets have experienced an extensive crisis with severe dampening effects in the entire global scenario. This has affected the Indian Mutual Fund Industry as well. In this backdrop, the present research paper endeavours to examine the impact of COVID-19 on the performance of direct plans of two open-ended Multi-cap funds [HDFC Equity Fund (HEF) and Kotak Standard Multi-cap Fund (KSMF)] based on certain parameters. This secondary data-based study covers 5-year period (2015-2020). The criterion for selecting the funds was net assets above Rs.15,000 crores as on 31.03.2020. Results reveal that the funds and the benchmark (Nifty 500 TRI) experienced reduced returns with increased risks and reduced risk-adjusted returns due to pandemic COVID-19. However, KSMF outperformed the benchmark while HEF underperformed the benchmark both before and after COVID-19. Further, HEF remained aggressive with inefficient fund management whereas KSMF was defensive with superior stock-picking by fund managers. However, both the funds remained adequately diversified before and after COVID-19.
Sustainability in a Changed World- A Report on Two Kiwi Organizations
Authors: Chowdhury Alapan Roy
Published: September 2022

The author has focused on the various objectives and activities that two New Zealand-based community organisations named Go Eco and Waikato Waldorf School are involved in, and how they are aligned with some of the United Nations' Sustainable Development Goals (SDGs) which were framed with the objective of making the earth a better place. The research was mixed, but it was predominantly primary. The author came in touch with (and interviewed) multiple members of the staff of Go Eco and Waikato Waldorf School. I have gained further and in-depth insights into those various activities from them. The research findings helped in bringing out the real picture, which was positive, and perfectly in line with what the organizations have on their website. Although the influence of these organisations is limited to Hamilton city or the Waikato district, their activities, in turn, help in achieving the SDGs. The findings and analysis showed the level of their involvement and reflected the extent of their impact. It helped the author link his investigations with the literature review and the knowledge about the organisations he gained from their official websites. Thus, he suggested some recommendations. He has mentioned how these expanding organisations could work in association with the New Zealand government, which is supporting the United Nations' cause and the SDGs, to reach the people in other parts of the world in post-pandemic times.
Role of Government to Boost up the Food Processing Industry- A Study with Reference to Covid19 Pandemic
Authors: Das Sankar
Published: September 2022

Micro, Small and Medium Enterprises (MSME) are facing several problems due to the pandemic. The Food Processing Industry (FPI) is considered the sunrise sector of MSME. FPI establishes linkages and synergy amongst the primary, secondary, and tertiary sectors. More than 40000 registered and 25 lakh unregistered food processing units exist in India, in which 7 million labours are engaged. Due to the sudden lockdown, huge quantities of raw materials and finished products have started to rot, and many units have been forced to shut down, and a huge number of workers in this industry have lost their jobs. The industry needed strong Government intervention to survive this crisis. The study has tried to focus on the impact of lockdown on FPI and the role of the government in boosting this industry during the current crisis period. The study is based on secondary data. The Central Government has tried to boost the industry by announcing a financial package of Rs. 10,000 crores for the establishment of micro food enterprises, changing the definition of MSME and providing relaxation in tax and other laws. A positive approach by the Central Government will definitely support the food processing industry to turn around under this critical situation.

Authors: Soelar Shahrul Aiman , Ahmad Mustaffa Nurakmal
Published: September 2022

Introduction: Social media has been a major source of various parties obtaining misinformation about vaccination programs and it has raised doubts about the vaccine, especially among parents. Vaccine hesitancy was listed as one of the top ten issues that threaten global health by the World Health Organization (WHO) in 2019. Therefore, this study aimed to examine sentiment on vaccines from Facebook pages, focusing on Facebook users’ views on vaccination programs through a mixed-method approach, which is a qualitative and quantitative combination analysis. Methods: This analysis uses all comments posted on Facebook pages downloaded using Facepager software from 01 December 2020 to 31 December 2020. R software is used to clean the comments and performed the sentiment analysis, while Gephi software is used to perform the semantic network analysis. Results: Out of 5,055 comments, the majority of the comments are negative sentiment (49.33%), followed by positive (32.58%) and neutral (18.08%) sentiment. For the negative sentiment, tolak, mati, and cucuk were the most frequent words ever used. For the positive sentiment, terima, setuju, and selamat were the most frequent words ever used. The positive network centered around the word dajjal focused on the word lab and FDA. In contrast, the negative network centered around the word vaksin focused on the word semulajadi and kerajaan. Conclusion: These findings are useful to understand the problem of parents who are skeptical of the vaccination program and also can be a guide for public health to communicate with the public through social media.

Teak is a wood-producing plant that is in great demand by the community. However, teak seeds are challenging to germinate due to dormancy, so special treatment is needed before planting. This research aimed to determine the effect of hydrochloric acid and soaking time on breaking the dormancy of teak seed to improve its viability. The first factor was the concentration of hydrochloric acid with four treatment levels, i.e., 0 M, 0.5 M, 1 M, and 1.5 M. The second factor was submerging time which was 12, 18, and 24 hours. Parameters observed included the percentage of germination, maximum growth potential, vigor index, germination rate, growth simultaneity, plant height, number of leaves, and wide leaf. The data obtained were analyzed statistically using ANOVA and followed the DMRT test with a level of 5%. The results showed that hydrochloric acid significantly affected the percentage of germination, maximum growth potential, vigor index, germination rate, growth simultaneity, plant height, and width of the leaf. In addition, soaking time treatment had a significant effect on the wide leaf. The research concluded that hydrochloric acid 0.5 M and 12 hours of soaking time increased the growth of teak seed compared to the control by 29.64% on a percentage of germination, 29% on germination rate, and 41.66% on growth simultaneity.

Background: Violence against medical assistants (residents) by colleagues is a serious problem at educational hospitals that has not been sufficiently examined. The present study was conducted to determine the prevalence, risk factors, and types of violence perpetrated by colleagues against medical assistants. Methods: In a cross-sectional study conducted at two large tertiary referral educational hospitals, the study questionnaires were distributed among 480 healthcare professionals to investigate their experiences of violence. Results: Of 280 responders, 162 residents (57.9%) reported a history of violence or aggression. Of these, nearly 50% had experienced pure psychological violence, and 16.7% had been physically abused. The prevalence of victimization was high among the residents of the neurosurgery, orthopedic, and obstetric departments (90%, 88%, and 85%, respectively). Conclusion: Harassment experience was more common among the surgical residents than the internal medicine residents because of the former’s high level of work stress. Senior residents or fellowship residents were the main abusers. Losing professional selfesteem, decreasing job satisfaction, and dropping out of school were the main adverse outcomes of violence experienced by the victims.
Brothers in the kitchen: the uprising, exodus and survival of a Tamily minority
Authors: Sundar Singh Cyrus
Published: September 2022

Brothers In the Kitchen (BiTk), is a site-specific live-documentary performed with an audience inside a fully operational restaurant. The triumvirate of story, performance, and audience is used to create an interactive and immersive documentary experience incorporating oral storytelling, poetry, dance, music, archival materials and television— all performed live. BiTk is the story of the uprising, exodus and survival of Tamil Sri Lankan citizens who fled a brutal civil war and sought refuge in Canada. The ethnic conflict, between the Buddhist Sinhala majority and the Hindu Tamil minority, sparked a mass exodus following the deadly riots of Black July in 1983. Subsequently, a staggering 300,000 Tamils found asylum in Canada. Soon an inordinate number of them began work as cooks and dishwashers in many Canadian restaurants. This live documentary is performed thirty years after the arrival of the first boatload of Tamil refugees, found adrift off the coast of Newfoundland, in 1986.
Aiolis te Pers Kimliği Hakkında Yeni Bir Katkı: Akinakes Betimli Tisna Sikkeleri
Authors: ERDAN Emre
Published: September 2022

Bu çalışmada, Tisna kentinin sikke serilerinden biri ve bu seri üzerindeki akinakes betimleri aracılığıyla Aiolis’te Pers kimliğine dair yeni veriler incelenecektir. İzmir ili, Aliağa ilçesi sınırlarında yer alan Tisna hakkında ilk bilgilerimiz Plinius tarafından aktarılır. Plinius sonrası herhangi bir metinde adı anılmayan kentte ilk incelemeler A. Conze tarafından 1900’lü yılların başında gerçekleştirilmiştir. 2018 yılından bu yana kentte yürütülen arkeolojik araştırmalar neticesinde daha detaylı bilgi sahibi olunmaya başlanan kentte Tisna sikkelerinden çok sayıda örnek ele geçmiştir. Bu sikkelerin arka yüzlerinde akinakesli tipin daha yoğun olduğu anlaşılmıştır. Pers kimliğini yansıtmak adına sembolik bir anlam ifade ettiğini düşündüğümüz akinakeslerin niçin Tisna sikkelerinde betimlendiği ve bu sikkelerin MÖ 4. yüzyılın hangi aşamasında üretilmiş olabilecekleri sorularına yanıt aramak, bu çalışmanın ana konusu olmuştur. Sonuç olarak, Tisna’nın akinakes betimli sikkelerinin en azından MÖ 387-386 yıllarında yapılan Antalkidas Anlaşması ile Makedon komutanların bölgede hakimiyeti ele geçirdikleri MÖ 334 yılları arasında üretilmiş olabileceği önerilir. Antik metinler aracılığıyla bilinen Orontes isyanı sırasında darp edildiği bilinen sikkelerin Tisna örnekleri olabileceği ve bu senaryoda Tisna akinakesli sikkelerinin MÖ 360-334 yılları arasına tarihlenmesi gerektiği de önerilmiştir. Bununla beraber, Orontes ile Autophradates arasında MÖ 360’larda Kyme önlerinde yaşandığı belirtilen savaşın Tisna teritoryumunda gerçekleşmiş olabileceği de düşünülmektedir.

Published: September 2022

Price formation of yam in the urban and rural markets of the Western agricultural zone of Nassarawa State, Nigeria has been an issue as many factors has been found to be contributing factors in the formation of yam price in the study area. Well-structured questionnaire was used to source for data from 141 hundred randomly selected yam marketers from the urban and rural markets in the zone, the rural markets were Andaha, Anguwan Zaria, Sabon Gida and Gudi while the urban markets includes Garaku, Akwanga, Nassarawa Eggon and Wamba. Descriptive statistic such as frequency, mean, and percentages was used to analyze the data. The result obtained revealed that majority (60%) and (62.5%) were male in the urban and rural markets respectively, with the mean ages of 47 years and 43.9 years respectively. The mean household size was 7 and 6 members for the urban and the rural households respectively. The average yam prices in ₦/kg in the urban /rural markets shows that the highest price was recorded in the urban market (Nassarawa Eggon) and the least price recorded in the rural market (Andaha), the Jarque-Bera test of normality shows that the prices of yam were normally distributed, of all the constraints to yam price formation, poor feeder roads, few number of buyers ranked most in the urban while  poor feeder roads, and inadequate access to credit facilities ranked topmost in rural markets. Therefore the research suggests a deliberate government policy towards rehabilitation of roads linking the rural and urban markets, and this may enhance trade between urban and rural markets.

The aim of the work is to develop and implement a technology for identifying similar series, and to test on series of data represented by hydrological samples. The subject of the study is the methods and approaches for identifying similar series. The object of the study is the process of identifying similar series, which are represented by certain indicators. The task is to propose and implement distance measures, where one of them takes into consideration the similarity between the values of the series and their relationship, and another is based on a weighted Euclidean distance taking into account the need to actualize the values that are the most important under certain conditions of the task; to implement a technology to find similar series represented by certain indicators values; to obtain a more resilient solution, to implement a procedure for determining a set of similar series based on the results obtained for each individual distance; the results should be analyzed and the conclusions have to be drawn dealing with practical application of the technology. The following methods were used: statistical analysis methods, methods for calculating distances, and similarity between data series. The following results were obtained: the technology for similar data series detection has been implemented; two distance measures were proposed and described as a part of the technology implemented; a procedure for determining a set of similar rows was implemented that was based on the obtained distances calculation. The scientific novelty of the research under discussion involves: Euclidean weighted distance was described and applied taking into account the actuality of data series values; a new measure of distance has been described and applied that allows both the degree of similarity between the values of the series and their correlation to be taken into account, as well as a technique has been developed for determining similar series from a set of selected distance measures. The practical importance of the developed and implemented technology consists in the following possibilities application to data series of different applied fields: conducting an assessment and identifying some similar series, in particular as an intermediate step in the analysis; in addition, the proposed distance measures improve the quality of identifying similar data series. In our further research, we plan to investigate the possibilities of lengthening the data series and filling in the gaps with values from other series defined as similar ones.

Whither Democracy in Palestine? Palestinian Public Opinion Surveys towards Democracy, 1997–2016
Authors: Mi’ari Mahmoud , Schulz Michael
Published: September 2022

This article examines the extent of Palestinian public support for democracy through the time period from 1997 to 2016. The analysis is based on data collected from five public surveys launched in the West Bank (including East Jerusalem) and the Gaza Strip. Our findings show that evidently the Palestinians support almost all elements of democracy, measured in these surveys, and support moderately few others, especially freedom of establishing parties and not using violent means to overthrow a ‘bad’ government. Our findings also reveal that this support is nearly constant and has not changed significantly since the early years of the Oslo accords era until recently. Based on these findings, and a few others revealed by using multiple regression analysis, we argue that Palestinian public opinion is not fully democratic, but rather is semi (or nearly) democratic. We also argue that the cultural hypothesis, claiming that Muslim Arab culture is incompatible with democracy, has no support according to the empirical evidence of this study.

Intervertebral disc (IVD) degeneration (IDD) is a common musculoskeletal disease and its treatment remains a clinical challenge. It is characterised by reduced cell numbers and degeneration of the extracellular matrix (ECM). Nucleus pulposus (NP) cells play a crucial role in this process. The purpose of this study is to explore the role of bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor, in the treatment of IDD through local drug delivery. High expression of VEGF was observed in degenerating human and rat IVDs. We demonstrated that MMP3 expression was decreased and COL II synthesis was promoted, when VEGF expression was inhibited by bevacizumab, thereby improving the degree of disc degeneration. Thus, these findings provide strong evidence that inhibition of VEGF expression by local delivery of bevacizumab is safe and effective in ameliorating disc degeneration in rats. The injectable thermosensitive PLGA-PEG-PLGA hydrogels loaded with bevacizumab is a potential therapeutic option for disc degeneration.

Photothermal therapy (PTT) has attracted extensive attention in cancer treatment due to its non-invasiveness, high efficiency, and repeatability in recent years. Photothermal agents (PTAs) are the key factor for PTT. Recently, although an increasing number of PTAs have been developed, there is still a great demand for optimized photothermal nanoparticles (NPs) with low toxicity, bio-safety and stability. Herein, new indocyanine green (IR820) with near-infrared (NIR:700–1,700 nm) fluorescence emission was selected as a photothermal agent (PTA). To enhance the PTT property, IR820 was encapsulated with another kind of PTA, polydopamine (PDA) under alkaline conditions. Furthermore, to improve the biocompatibility of the NPs, methoxy polyethylene glycol amine (mPEG-NH2) was modified via a Michael addition to form a novel kind of IR820@PDA@PEG NPs. After detailed characterization and analysis, the obtained IR820@PDA@PEG NPs showed a spherical shape with an average diameter of ∼159.6 nm. Meanwhile, the formed IR820@PDA@PEG NPs exhibited better photostability and lower cytotoxicity than free IR820 molecules. The photothermal performance of IR820@PDA@PEG NPs was further analyzed in vitro, and the temperature of IR820@PDA@PEG NPs (100 μg/ml) reached 54.8°C under 793 nm laser irradiation. Afterwards, the cellular uptake of IR820@PDA@PEG NPs was evaluated via confocal laser scanning fluorescence microscopic imaging. Then, PTT experiments on HeLa cells demonstrated that IR820@PDA@PEG NPs can hyperthermal ablate cancer cells (∼49.1%) under 793 nm laser irradiation. Therefore, IR820@PDA@PEG NPs would be a promising PTA for the treatment of cervical cancer HeLa cells.
Vasodilatory effects of glucagon: A possible new approach to enhanced subcutaneous insulin absorption in artificial pancreas devices

Patients with diabetes mellitus type 1 depend on exogenous insulin to keep their blood glucose concentrations within the desired range. Subcutaneous bihormonal artificial pancreas devices that can measure glucose concentrations continuously and autonomously calculate and deliver insulin and glucagon infusions is a promising new treatment option for these patients. The slow absorption rate of insulin from subcutaneous tissue is perhaps the most important factor preventing the development of a fully automated artificial pancreas using subcutaneous insulin delivery. Subcutaneous insulin absorption is influenced by several factors, among which local subcutaneous blood flow is one of the most prominent. We have discovered that micro-doses of glucagon may cause a substantial increase in local subcutaneous blood flow. This paper discusses how the local vasodilative effects of micro-doses of glucagon might be utilised to improve the performance of subcutaneous bihormonal artificial pancreas devices. We map out the early stages of our hypothesis as a disruptive novel approach, where we propose to use glucagon as a vasodilator to accelerate the absorption of meal boluses of insulin, besides using it conventionally to treat hypoglycaemia.
HMGB1 is a mediator of cuproptosis-related sterile inflammation

Published: September 2022

Cuproptosis is a recently recognized modality of cell death driven by intracellular copper-dependent mitochondrial stress. However, the mediators of the sterile inflammatory response to cuproptotic death are undetermined. Here, we report that high-mobility group box 1 (HMGB1), a damage-associated molecular pattern, is released by cuproptotic cells to initiate inflammation. Mechanically, copper accumulation-induced adenosine triphosphate (ATP) depletion activates AMP-activated protein kinase (AMPK) to promote HMGB1 phosphorylation, resulting in increased extracellular release. In contrast, genetic (using RNAi) or pharmacologic (using dorsomorphin) inhibition of AMPK activation limits cuproptosis and HMGB1 release. Functionally, the ability of HMGB1-deficient cuproptotic cells to promote advanced glycosylation end product-specific receptor (AGER, also known as RAGE)-dependent inflammatory cytokine production is greatly reduced. Thus, HMGB1 is a key immune mediator of cuproptosis-initiated sterile inflammation.

Open thoracoabdominal aortic aneurysm (TAAA) repair is a complex and challenging operation with a high incidence of serious complications, and high perioperative mortality and morbidity. Left heart bypass (LHB) is a circulatory support system used to perfuse the distal aorta during TAAA operation, and the advantages of LHB include guaranteeing distal perfusion, reducing the use of heparin, and diminishing the risk of bleeding and postoperative neurological deficits. In China, the circuit for TAAA repair is deficient, and far from the perfusion requirements. We designed a modular multifunctional LHB circuit for TAAA repair. The modular circuit consisted of cannulation pipelines, functional consumables connection pipelines, and accessory pipelines. The accessory pipelines make up lines for selective visceral perfusion and kidney perfusion, suckers and rapid infusion. The circuit can be assembled according to surgical requirements. The ultrafilter and heat exchanger are integrated into the circuit to fulfill the basic demands of LHB. The LHB circuit also has pipelines for selective visceral perfusion to the celiac artery and superior mesenteric artery and renal perfusion pipelines. Meanwhile, the reserved pipelines facilitate the quick switch from LHB to conventional cardiopulmonary bypass (CPB). The reserved pipelines reduce the time of reassembling the CPB circuit. Moreover, the rapid infusion was integrated into the LHB circuit, which can rapid infusion when massive hemorrhage during the open procedures such as exposure and reconstruction of the aorta. The ultrafiltration can diminish the consequent hemodilution of hemorrhage and rapid infusion. A hemoperfusion cartridge also can be added to reduce the systemic inflammatory during operation. The circuit can meet the needs of LHB and quickly switch to conventional CPB. No oxygenator was required during LHB, which reduce the use of heparin and reduce the risk of bleeding. The heat exchanger contributes to temperature regulation; ultrafiltration, arterial filter, and rapid-infusion facilitated the blood volume management and are useful to maintain hemodynamic stability. This circuit made the assembly of the LHB circuit more easily, and more efficient, which may contribute to the TAAA repair operation performed in lower volume centers easily. 26 patients who received TAAA repair under the modular multifunctional LHB from January 2018-March 2022 were analyzed, and we achieved acceptable clinical outcomes. The in-hospital mortality and 30-day postoperative mortality were 15.4%, and the postoperative incidences of paraparesis (4%), stroke (4%), and AKI need hemodialysis (12%) were not particularly high, based on the limited patients sample size in short research period duration.
