Effect of Some Plant Growth Hormones on the Performance of Artemisia vulgaris L. Cuttings

In the wake of the novel coronavirus (COVID-19), many plant material such as artemisia (Artemisia vulgaris L) have received renewed attention as cheap, easy-to-make treatment for many infections. However, the proliferation of artemisia from seeds is often a lengthy process. Here we investigated the role of commercial (Indol-3-butyric acid - IBA, Natural Rooting Hormone Powder - NRHP, Apple Cider Vinegar - ACV) and cottage-made (coconut water - CW and aloe vera gel - AVG) rooting hormone, and water as control (CONT) on the proliferation of artemisia cuttings in a greenhouse experiment in 2021. The survival of artemisia cuttings did not differ significantly (P > .05) across the treatments. The highest number of stems (19) and plant height (138.0 cm) was observed from CW + AVG, and the differed significantly from the others (P < .05) from the others. AVG produced the highest number of leaves per plant (1466), followed by CW (1317), CW + AVG (1278), and IBA (1241). The leaf dry weight was highest in CW + AVG, followed by those of CW and IBA. A similar pettern was observed for the root dry weight. The findings from this study showed that cottage-made plant based (coconut water and aloe vera gel) growth hormone has comparable effect to commercially available IBA on overall performance of artemisia cuttings. This study has great implications for low-tech proliferation of artemisia.

Fruits as Boosters of the Immune System

Immunity is the major mechanism of host defence system against infectious and chronic diseases. The recent global concern of recent viral infection of SARS-CoV-19 has raised the demand of functional foods, nutraceuticals and fruits that can boost immunity. This will help in managing the overall physiological health and prevention of infectious and chronic diseases. Medicinal plants and fruits can help in boosting immunity through modulation of immune system and changing the types of immune response such as involvement of the induction, expression or amplification of the genes and proteins in inflammation and antioxidant system. The traditional medicine systems have used a wide variety of plants and fruits as supplement for immunomodulation including those for stimulation of immune system as well as immune compromisation deemed per se. Some of the plants that have been listed for immune boosting abilities included Curcuma longa, Withania somnifera, Phyllanthus emblica, Azadirachta indica, Panax ginseng, Rhododendron spiciferum, Caesalpinia bonducella, Tinospora cordifolia, Capparis zeylanica, Asparagus racemosus, Nelumbo nucifera, Arnica montana, Calendula officinalis, Echinacea purpurea and Euphorbia tirucalli. Reports indicate that a wide variety of phytochemicals like polysaccharide, alkaloids, flavonoids, terpenoids, lactones and glycoside have shown immunomodulatory properties under different pathophysiological conditions. Amongst the diverse chemical profile of plant extracts, polysaccharides are the water-soluble molecules that could activate immune responses when interacting directly with immune cells, while hydrophobic compounds like flavonoids such as quercetin and luteolin and terpenoids such as sesquiterpene lactones and curcumin showed potent immunomodulatory effects. Growing evidences suggest that phytochemicals from functional foods and fruits may be useful in maintaining the cytokine and chemokine balance, regulating oxidative status of cells, and targeting the specific cellular receptors as therapeutic targets. This chapter comprehensively enlists the plant resources with immune boosting abilities and explore their phytochemical characterization and molecular mechanism behind their protective effects. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

Changes in the characteristic of dietary and lifestyle during Covid-19 lockdown in different countries: A systematic review

Due to the covid-19 pandemic, governments were forced to adopt lockdown policies to effectively control the pandemic. These restrictions increased anxiety, depression, and lifestyle changes. This systematic review aims to analyze changes in dietary patterns in the worldwide population during the COVID-19 lockdown. 11 studies were selected from the 1412 founds after searching in three databases. Searching keywords were: "Change dietary”, "COVID-19 dietary” "Confinement dietary”. Inclusion criteria were: studies that collected people's dietary patterns during the COVID-19 lockdown and recorded the consumption of food groups and the variations in lifestyle habits. This research found that people increased their consumption of food. People increased their sedentary hours, slept more but exercised less, leading to gain weight during the lockdown, as well as a poorer sleeping quality and higher anxiety levels.Alternate : Debido a la pandemia de COVID-19, los gobiernos se vieron obligados a tomar medidas de confinamiento para controlar eficazmente el contagio. Sin embargo, después de un tiempo de control al poblado, estas restricciones hicieron la gente tener más ansiedad y depresión, incluso cambiar el estilo de vida.

Food bioactive compounds, sources, and their effectiveness during COVID-19

Since the occurrence of COVID-19 pandemic in the late 2019, it has impacted to almost all the countries throughout the world by its severity of infection. The vaccines or drugs to combat the SARS-CoV-2 infection were not available till recent time, and the people looked out for healthy foods, which help to increase the immune response. Even after the vaccines have been developed for the COVID-19, the importance of food-based diet cannot be neglected due to their health beneficial properties, which are required post-COVID-19 infection or during the incubation duration of infection. Several food groups and their products have been known to provide vital nutrients, which are required for proper functioning of human body. Along with nutrients, these foods are known to have various nonnutrients components, which help in reduction or management of several physiological disorders. These compounds are collectively known as bioactive compounds, which are naturally synthesized. These compounds are widely spread and abundantly found in plant-based foods. The major groups of bioactive compounds present in foods include polyphenols, carotenoids, bioactive carbohydrates, and phytosterols. These compounds are known to have mainly the properties of antioxidant, anti-inflammatory, anticancerous, and antimicrobial, which helps in keeping the human body healthy. In this chapter, the main bioactive compounds, their classification, and food sources have been highlighted, which will give an insight of their beneficial effects. The bioactive compounds will have a major role in reduction of inflammation and infection through several complex physiological mechanism, thereby involved in increasing the immunity. Hence, these compounds play a vital role in management or reduction of COVID-19 infection through the effectiveness of bioactive compounds. © 2023 Elsevier Inc. All rights reserved.

Masked Face Recognition Using Multi-Task Cascaded Convolutional Networks and FaceNet

Face masks have been widely used since the start of the COVID-19 pandemic. Facial detection and recognition technologies, such as the iPhone's Face ID, heavily rely on seeing the facial features that are now obscured due to wearing a face mask. Currently, the only way to utilize Face ID with a mask on is by having an Apple Watch as well. As such, this paper intends to find initial means of a reliable personal facial recognition system while the user is wearing a face mask without having the need for an Apple Watch. This may also be applicable to other security systems or measures. Through the use of Multi-Task Cascaded Convolutional Networks or MTCNN, a type of neural network which identifies faces and facial landmarks, and FaceNet, a deep neural network utilized for deriving features from a picture of a face, the masked face of the user could be identified and more importantly be recognized. Utilizing MTCNN, detecting the masked faces and automatically cropping them from the raw images are done. The learning phase then takes place wherein the exposed facial features are given emphasis while the masks themselves are excluded as a factor in recognition. Data in the form of images are acquired from taking multiple pictures of a certain individual's face as well as from repositories online for other people's faces. Images used are taken in various settings or modes such as different lighting levels, facial angles, head angles, colors and designs of face masks, and the presence or absence of glasses. The goal is to recognize whether it is the certain individual or not in the image. The training accuracy is 99.966% while the test accuracy is 99.921%. © 2022 IEEE.

It has been determined that anxiety about COVID-19 is higher in individuals and women who start using nutritional support during the pandemic period. The total C19P-S and STAI scores of those who started using a dietary supplement during the pandemic were significantly higher than those who did not use a dietary supplement. Similarly, those whose eating habits changed positively and those who bought more packaged products had higher C19P-S scale mean scores (p < 0.05).Originality/valueDuring the COVID-19 period, it is important to reduce the anxiety levels of individuals, provide psychological support, raise awareness of adequate and balanced nutrition and the correct use of dietary supplements to adapt to the new lifestyle.

A call for food system change

[...]the UK meets more of its food needs, the country risks having potentially counterfeit food imports and disrupted supply chains. The book describes relevant aspects of British food history, defines terms, lists foods imported and exported, measures freight shipped through UK airports, defines greenhouse gas emissions from livestock and crop production, documents food price trends, gives feed conversion rates for food animals, lists advertising spending by major food companies, explains water rights, and states how much land is owned by the British aristocracy, corporations, and Crown. Lang was a member of the EAT-Lancet Commission and he calls on the UK Government to adopt the Commission's Great Food Transformation recommendations to improve public health, the environment, food citizenship, wage scales, and democratic accountability, and to redistribute power in the food system.

The role of healthy eating and functional foods in the protection of the immune system, especially the consumption of vegetables and fruits: lifestyle survey among adult population

Our manuscript focuses on vegetables and fruits as functional foods. Our questionnaire survey was conducted at the end of the third wave of the pandemic, however, we also paid increased attention to lifestyle, mostly dietary, changes in the active stages of the coronavirus pandemic, especially vegetable and fruit consumption patterns. Our quantitative analysis was carried out with the help of 9 questionnaires, including 4 cumulative closed-ended questionnaires, which were divided into four main groups of statistical activities. We first analysed demographic data and then focused on health status, knowledge of concepts, and assessment of consumer needs. For the statistical evaluation of our survey, we performed a descriptive statistical analysis, including a distribution analysis of demography and related issues. Next, we calculated the appropriate type of correlation between the questions, which was evaluated in Microsoft Excel and IBM SPSS Statistics 26. The number of respondents was n = 109, of which 37% were male and 63% female. Before evaluating our results, we also asked a research question: To what extent did the attitudes related to regular exercise, healthy eating and the importance of health change during the active stages of the pandemic? Based on our empirical analyses, an increase in extremes can be observed with regular exercise. In terms of general health, there was an increase in the "extremely important" category. In the active phase of the pandemic, the number of vegetable consumers was lower, and among the proponents of a healthy diet, the consumption of fruit foods was not significantly higher. Based on our conclusions, this is due on the one hand to the restrictions during the pandemic and on the other hand to the endowment of fruit-containing foods with negative properties (e.g. made with the addition of sugar).

Pandemic Produce: Impacts of COVID-19 on Florida's Fruit and Vegetable Industries

Florida has one of the most diverse agricultural economies in the United States, producing several dozen types of fruits and vegetables that are consumed within the state, across the country, and around the world. The COVID-19 pandemic and resulting policy responses occurred during the peak of spring harvest season for many crops in Florida, abruptly removing market demand from the food service industry and shifting consumer purchasing habits, which enabled insights into several aspects of the fruit and vegetable supply chain. This article examines how the COVID-19 pandemic impacted fruit and vegetable industries in Florida, how these industries responded to COVID-19 impacts, and how Florida's experience compared to that of other states. Data are derived from several sources including a statewide survey that measured agricultural production losses in Florida resulting from COVID-19 in early 2020, interviews with Florida operations that provided insights into how the pandemic induced change across the food supply chain, and a survey of food supply chain operations in three regions of the United States conducted in 2021. © 2022 Walter de Gruyter GmbH, Berlin/Boston.

Fruit characterization and plant quality of Spanish cedar (Cedrela odorata L.) during the early nursery stage

Objective: The aim of this study was to characterize Spanish cedar (Cedrela odorata L.) fruits and seeds, and to evaluate the effects of provenance, substrata, and fertilizer on germination and plant quality in nursery. Design/Methodology/Approach: The fruits and seeds from Spanish cedars were collected in three different towns: C-32 (Francisco Trujillo Gurria), C-40 (Ernesto Aguirre Colorado), and C-41 (Carlos A. Madrazo). Those towns are in Plan Chontalpa, Tabasco, Mexico. After they were harvested, the samples were morphometrically characterized. Seed production efficiency (SPE), germination (%), and Dickson Quality Index (DQI) were estimated. Two completely randomized experimental designs with factorial arrangement of treatments were used. The factors were the provenance, four or three substrata, and two levels of GreenfoolR 600 fertilizer. Results: Fruits of 3.46 cm in length and 1.81 cm in width were collected;the mean number of seeds per fruit was 49.36. Seed production efficiency ranged from 48.1% to 52.72%, with 32.86% germination. The seeds from Town C-41 obtained the highest germination percentage, with the use of black soil:sand as substrate. The plants fertilized and developed in black soil:sand substrate obtained a higher DQI. Study Limitations/Implications: The activity restriction caused by the Sars-Cov-2 pandemic was the main limitation. The lower number of producers and plantations from Town C-32 was the implication. Findings/Conclusions: Fruit and seed characteristics were different among provenances. The provenance impacted on seed germination, but not on the plant quality index (DQI). Instead, the substrate and fertilizer impacted on the DQI.

An integrated IoT architecture to monitor food quality along the supply chain

Drop in nutrition value during food logistics impacts the health of consumers. Vegetables, fruits, fish, milk lose nutrients during logistics if it is not properly monitored. Real-time tracking and monitoring, large data handling and secure business transactions are key to the effective operation of supply chains. The COVID-19 pandemic has taught us the need for handling unforeseen situations in various sectors. Limitations to logistic operations, inaccessible warehouses, shutdown of consumer outlets for an unexpected duration, have affected the supply chain drastically. This has laid emphasis on the need for technology-based solutions that can monitor, control and make quick decisions, that can reduce losses. With this scenario as a background, a system architecture has been proposed to detect the nutrient value of food by periodically monitoring temperature and humidity in real-time and alerting the cold chain entities in cold chain environments. This architecture is proposed as an integration of Internet of Things (IoT) with cloud-based storage, to provide real-time data collection at the end-user, seamless storage and computation in the cloud and secure transactions at the business layer. An experimental setup of the system architecture has been configured and the implementation has been tested at a preliminary level. The performance of the application is analyzed and the proposed web application is efficient for large scale supply chain applications, provided scaling of hardware resources.

Rapid monitoring of SARS-CoV-2 on fruits and vegetables using reverse-transcription loop-mediated isothermal amplification assay

COVID-infected people handling fruits and vegetables may spread the virus to healthy people on contact. Here we examined if SARS-CoV-2 was detectable on the fruits, vegetables, hand gloves and packaging materials collected from the open markets and pack houses in India. During the study (2021-22), swabs from 748 samples representing the majorly traded items were tested using RT-LAMP assay. The sensitivity and specificity of the kit were found to be equivalent to the RT-PCR assay. All test samples were found negative for SARS-CoV-2. Thus, it can be concluded that the virus is unlikely to spread to foods and packaging materials through human contact.

Analysis of changes in shopping habits and causes of food waste among consumers before and during the COVID-19 pandemic in Poland

Food waste is a worldwide phenomenon that needs to be reduced. The causes of this problem vary widely. The study used the Computer-Assisted Web Interview method. There were 500 respondents from all over the country and among them 60% women and 40% men. The sample selection was purposeful. Before the pandemic began, the highest percentage of consumers shopped two to three times a week. As of March 2020, the frequency of this activity has decreased for every fourth respondent. Also during this period, an increase in the frequency of shopping alone was observed, as well as an increase in the number of people who outsource their shopping list to others. Nowadays, the vast majority of respondents usually create a shopping list before doing it and follow it. Before the pandemic, this was the case for only 46% of respondents, while during the pandemic it was the case for 81%. Exceeding the expiration date was the most common reason for throwing products in the trash before as well as during the pandemic. Over-shopping as a cause of food waste increased almost fourfold during the pandemic. A positive aspect is noticeable for the 'I don't throw food away' response. The percentage of respondents increased from 16% to 21%. During both survey periods, respondents most often indicated that they throw away fruits, vegetables, bread, and dairy products. During the COVID-19 pandemic, consumers' shopping behaviour changed. They attended grocery stores far less frequently, mostly on their own, and purchased larger quantities of products. Nonetheless, consumers planned their purchases and checked expiration dates before putting food in their shopping carts. Households were thus forced to respond quickly, adjusting their shopping behaviour. These behaviours have implications for the subsequent activities of retail merchants.

Sanitization of fruits and vegetables: a review

Recently, with the coronavirus pandemic, the eating habits of the population have been modified, observing the search for healthy diet. In this sense, the consumption of fruits and vegetables has increased, and the hygiene is a fundamental step in quality control, since fruits and vegetables can be consumed in natura. The objective of the work was to elaborate a review about the main chemical sanitizers used in the sanitization of fruits and vegetables. The study is a review based on scientific publications, using the combination of the following descriptors: hygiene, fruits and vegetables, sanitizers and sanitizing. It was possible to verify that the most used sanitizer in the sanitization of fruits and vegetables is chlorine and its derivatives, in concentrations from 100 to 200 ppm, normally for 15 minutes. Ozone could destroy numerous microorganisms and for its sanitizing effect it is necessary to have a longer exposure time, on average up to 30 minutes. When using organic acids (acetic, citric, lactic and peracetic acid), the concentrations vary up to 2% and the average exposure time is a few minutes, which can be used in combination or not. However, its use is not always effective. It is concluded that the application of each type of sanitizer varies according to its concentrations, pH, exposure time to the treatment and the type of fruit or vegetable to be sanitized.

Social-ecological systems and social innovations regarding fruits and vegetables supply chains – case study of the Brazilian social enterprise Sumá

Approximately 70% of the food consumed in Brazil comes from family farming, mainly composed of small farmers. Small farmers are especially active in the fruits and vegetables (FV) chains in Brazil and were severely affected by the COVID-19 pandemic, contributing to the degradation in the country's food security. This paper explores how social innovation in the FV sector can contribute to social-ecological systems resilience and supply chain resilience, using as the main theoretical background the adaptive cycle framework. The article was based on documentary analysis and semi-structured interviews, exploring the FV sector issues at a macro-level and then focusing on the case study of Sumá, a social enterprise from Southern Brazil. Sumá develops small farmers and connects them to regular food purchasers in small towns, promoting sustainable food systems. This case study stands out as an example of how to identify, evaluate and take advantage of market opportunities and public sector gaps in order to generate economic growth and multidimensional social impact.

Pathways for advancing good work in food systems: reflecting on the international good work for good food forum

The crucial roles that workers, especially seasonal and migrant workers, play in our food systems have come under renewed attention in recent years. The coronavirus pandemic resulted in food workers being recognized as critical or essential workers in many countries. In 2021, this coincided with the UN International Year of Fruits and Vegetables (IYFV), highlighting the importance of horticultural crops to healthy lives globally. Yet, workers' quality of life in this most labor-intensive form of food production is often disregarded, or in the case of the UN IYFV, misconstrued. The agriculture-migration nexus-on which food systems depend-remains recognized as a challenge, yet there is limited debate about how it could be ameliorated and a lack of articulation of desirable alternatives. While alternative food and peasant movements propose food system transformation and alternative labor futures based on agroecology, labor lawyers and other advocates propose regulation and formalization of workplace regimes to ensure fair working conditions. Most recently, a third possibility has emerged from agri-tech innovators: a techno-centric future with far fewer agricultural workers. These three archetypes of agricultural labor futures (agroecological, formally regulated, and techno-centric) have the potential to leave food scholars and activists without a unified, coherent vision to advance. Addressing this gap, this paper reports and builds on insights harvested from the international Good Work for Good Food Forum, organized by the authors with the aim of shaping consensus on positive visions for work in food systems. About 40 scholar-activists across three continents discussed the current challenges facing food workers and crafted a collective vision for good food work. This vision is documented in the form of nine principles supported by a framework of seven enabling pathways. We conclude by emphasizing the need for a people-centered incorporation of technology and a re-valuation of food workers' contributions to global food systems. We offer the vision as a collective platform for action to advocate for and organize with workers in food systems.

Horticultural activities with lasting impact on urban communities, in the context of COVID 19 lockdown

Horticultural activities in urban areas and suburbs describe economically viable ways of production (North and Patterson, 2018), and are a continuous growing segment of production in developing countries as well as in Romania countries and are expected to have positive impacts on nutrition quality first and implicit on people's health. This comes as a necessity as the population is continuously growing as the land has a limited use. In a wide sense, urban horticulture includes everything from small home and community gardens to city park management, rooftop greening, as well as complex vertical way of production. This sector assures increased availability of fresh products (vegetables and fruits) in big cities, healthier diets, improved food safety, low transportation costs, efficient resource use, and the mitigation of environmental impacts of horticultural production such as the emission of greenhouse gases.
