ABSTRACT
Objective: Severe disease onset of COVID-19 may result in alveolar injury and respiratory failure. Apoptosis and inflammation are the main causes of respiratory distress syndrome. Berberine is used in medicine as an analgesic, anti-asthmatic, anti-inflammatory, and antiviral. In the current investigation, the effect of berberine on COVID-19 outpatients was studied. Materials and Methods: The present clinical trial was performed on 40 outpatients who were randomly assigned to berberine (300 mg, TID, 2 weeks) (n=19) or placebo groups (n=21). Both groups received standard therapy and they were monitored on days 3, 7, and 14 after the beginning of the therapy for clinical symptoms' improvement, quantitative CRP, lymphopenia, CBC, and SpO2. The severity and frequency of these symptoms and the level of the parameters were statistically compared between the two groups. Results: On days 0, 3, 7, and 14, there was no significant difference between the berberine and placebo groups in the improvement of clinical symptoms (cough, shortness of breath, nausea, loss of smell and taste, diarrhea, dizziness, sore throat, stomachache, body aches, and body temperature), quantitative CRP, lymphopenia, WBC, neutrophils, platelets, or SpO2. Conclusion: Berberine (300 mg, TID, two weeks) is ineffective in treating COVID-19. More research with a larger sample size is needed to investigate different berberine dosages in other pharmaceutical formulations.
ABSTRACT
Aim: The contagious disease COVID 19 is a recently out-broken pandemic situation which threatens humankind all over the world. Siddha system of medicine is one of the traditional medical systems of India, which has provided a novel remedy for many epidemics like Dengue, Chicken guinea earlier. On evaluating the literature evidence and considering the mortality and severity of the disease, we have attempted to identify the possible inhibition of viral replication by "Karisalai Chooranam" - a polyherbal Siddha formulation which contains herbs like Karisalai (Wedelia chinensis), Thoodhuvelai (Solanum trilobatum), Musumusukai (Melothria maderaspatana) and Seeragam (Cuminum cyminum). The aim of this study was to identify the bioactive components present in Karisalai chooranam and pin down the components that inhibit COVID 19 protease by In Silico molecular docking analysis. Material and methods: The study was performed for the active compounds present in the herbs (Wedelia chinensis - Benzoic acid, Solanum trilobatum- Disogenin, Melothria maderaspatana- beta-sitosterol, Cuminum cyminum L- Coumaric acid and Limonene) with three potential targets, PDB id: 6LU7 3-chymotrypsin-like protease (3CLpro), PDB id: 6-NUR RNA dependent RNA polymerase and PDB id: 2AJF Angiotensin-converting enzyme II (ACE2) receptor using Autodock Vina. Key findings: The active phytocomponents present in "Karisalai chooranam" was found to inhibit the target 3CL proenzyme and hereby halt the formation of 16 non-structural proteins (nsp1-nsp16) that are highly essential for viral replication and there by prevents viral survival in the host environment. The phytocomponents also inhibited the target RNA dependent RNA polymerase (PDB)-6NUR RdRp which possess versatile action in mediating nonstructural protein (nsp 12) essential for viral replication. A significant binding against the target Angiotensin-converting enzyme II (ACE2) receptors - PDB- 2AJF was found which was recognized as a binding site for novel coronavirus to cause its pathogenesis. Among the five active components present in the herb, the binding ability of Disogenin and beta-sitosterol with COVID19 protease suggests a possible mechanism of protease inhibition and thus preventing viral replication. Significance: The results strongly suggest that phytocomponents of "Karisalai chooranam" may act as a potential therapeutic agent for the management of COVID-19 and related symptoms. Further, the efficacy of the active compounds should be tested in vitro before being recommended as a drug.
ABSTRACT
Increasing body immunity is very necessary after the Covid-19 pandemic. One of the efforts that can be made to increase the body's immunity is to consume functional foods with immunostimulant activity, such as processed snakehead fish products in the form of nuggets, and "parkusel" juice made from a mixture of bitter melon, dates and celery. The purpose of community service is to provide knowledge and skills to housewives and the community at the Veteran ABRI Housing Complex in Medan Estate, Deli Serdang Regency, in making functional food products in the form of snakehead fish nuggets and Perkusel juice. The community service method used is the counseling method with leafet aids and training in making snakehead fish nuggets and perkusel juice. The results of the activity showed that there was an increase in the knowledge of the community participants in community service activities about nutritious snack products that can increase body immunity by 71% in the good value category.
ABSTRACT
Coronavirus was detected in Bangladesh first time on March 8, 2020 officially. But Coronavirus Disease (COVID-19), first reported in December 2019 from Wuhan in China, had reached the stage of a pandemic. This study was conducted to know the effects of spices against Covid-19 disease, impact of Covid-19 on agro-economy of spices crop and point out of mitigating of spices problem in Bangladesh. Major production of spices was severely affected, causing raw material shortages to the spice production of Bangladesh. Major for spices crop problem were shortages caused by the migration of the workforce due to lockdown. Continuing operation on the industry floor, in the midst of social distancing, and ensuring safety of the spices production, was also a major issue. Although the entire sectors were hit by the economic disruptions, the small-scale spice producers and processors most severely affected. The novel coronavirus disease (COVID-19) pandemic and the prolonged lockdown have made thousands of farmers, labours and traders feel the pinch of a falling spices yield and sale. Increased production cost of onion, chilli, garlic, ginger, turmeric, coriander and black cumin due to Covid-19 situation over normal situation were 10.33, 9.54, 9.04, 11.46, 9.58, 6.21 and 7.21%, respectively. Market price of onion, chilli, garlic, ginger, turmeric, coriander and black cumin were also increased 5.00, 3.90, 1.39, 3.13, 1.40, 1.25 and 2.67 times, respectively, due to the influence of Covid-19.
ABSTRACT
This study aims to analyze the AntiCovid effect of Phytocompounds extracted from Native Indian Plant species by computational methods such as Molecular Docking. Through this study keeping the Indian Heritage alive we characterized the ability of these phytochemicals as inhibiting agents of the Main Protease enzyme of this Virus. The lack of any effective treatment and the reoccurrence of cases despite Vaccination necessitates the quick provision of anti-SARS-CoV-2 drugs. Natural substances are getting a lot of attention for SARS-CoV-2 therapy as they have proven antimicrobial activities and are a key source for numerous antiviral drugs. Despite the fact that this virus has several identified target receptors, Main Protease (Mpro) is crucial for viral replication. In this study, 26 phytochemicals from 10 native Indian plant species were studied. Our docking studies demonstrated that compounds Quercetin, Withaferin A, Sominone, and Nimbin were likely to be more favorable than the natural inhibitor N3, with binding energies of-8.42, -9.21, -9.95, and -8.88 kcal/mol, respectively. These four candidate natural compounds were further examined for their bioavailability scores through ADMET analysis to prove the safety of these compounds as well as their drug likeliness. Through the results it was indicated that these natural phytochemicals have a significant potential of inhibiting the SARS-CoV-2 Mpro enzyme and might be utilized to treat SARS-CoV-2 and manage public health, subject to in vitro validation in the future.
ABSTRACT
Background: Antiviral vaccine is not effective, synthetic antiviral drugs are highly toxic, leading to increased interest in herbal medicines as promising antiviral drugs. Recently, Vipdervir has been developed from medicinal herbs with the aim to support and treat diseases caused by viruses such as H5N1 and SARSCoV- 2. In the present study, we assessed Vipdervir's antiviral activity against H5N1 and SARS-CoV-2. In addition, we also evaluated the acute toxicity and repeated dose toxicity of Vipdervir in mice and rabbits, respectively. Methods: H5N1 inhibitory effect of Vipdervir was assessed using hemagglutination inhibition assay. Vipdervir's SARS-CoV-2 inhibitory effect was evaluated by Plaque Reduction Neutralization assay. Acute and repeated dose oral toxicities of Vipdervir were determined according to OECD 423 and OECD 407 guidelines, respectively. Results: Data show that Vipdervir is effective against both H5N1 and SARSCoV- 2. At concentrations of 3 mg/mL and 5 mg/mL Vipdervir completely inhibits H5N1. At a concentration of 50 g/mL Vipdervir showed an inhibitory effect on SARS-CoV-2. Acute toxicity data revealed that the LD50 of Vipdervir is greater than 35200 mg/kg, b.wt. in mice. Repeated toxicity data indicated that Vipdervir did not induce significant differences in body weight gain, hematology and clinical biochemistry in compared to the control group. The No Observed Adverse Effect Level of Vipdervir is greater than 613.8 mg/kg b.wt./day in rabbits. No delayed toxicity effects of Vipdervir were observed. Conclusion: Vipdervir capsules were found to be antiviral effective and relatively safe in the tested doses and experimental conditions.

ABSTRACT
Various kinds of field crops growing on two commercial farms in the Whitehorse area of the southern Yukon Territory were surveyed for diseases in summer 2020 by staff of the Agriculture Branch of the Government of Yukon. They included barley, wheat, canola, beets, broccoli, cabbage, carrots, potatoes and turnips. Fields were visited one or more times during July and August. The incidence and severity of diseases were visually assessed on a crop-by-crop basis and samples were collected for laboratory analysis of the pathogens present, if any. Both infectious and non-infectious diseases were present on most crops. The infectious diseases were caused by various species of plant pathogenic bacteria and fungi that were common on these crops growing in other areas of Canada. INTRODUCTION AND METHODS: The 2020 field crop disease survey is believed to be the first organized study of its kind on agricultural crops in the Territory. In his book, "An Annotated Index of Plant Diseases in Canada . . . ", I.L. Conners lists over 300 records of plant diseases on trees, shrubs, herbs and grasses in the Yukon that were published by individuals who were surveying forests and native vegetation mainly for federal government departments, universities and other agencies (Conners 1967). The objectives of the 2020 survey were: (1) to determine the kinds and levels of diseases on selected Yukon crops, (2) to identify the major pathogen species attacking Yukon crops, and (3) to use the results to plan future surveillance activities aimed at helping producers to improve their current disease management programs. All of the fields included in the 2020 survey were situated on two commercial farms, which were designated as Farm #1 and #2, in the Whitehorse area in the southern Yukon (Fig. 1). The crops surveyed included cereals (barley and wheat), oilseeds (canola) and vegetables (beets, broccoli, cabbage, carrots, potatoes and turnips). Fields were visited one or more times in the mid- to late growing season (July/August) at a time when damage from diseases was most noticeable. Symptoms were visually assessed on a crop-by-crop basis by determining their incidence and severity. Incidence was represented by the percentage of plants, leaves, heads, kernels, etc., damaged in the target crop, while severity was estimated to be the proportion of the leaf, fruit, head, root/canopy area, etc., affected by a specific disease as follows: Proportion of the canopy affected based on a 0-4 rating scale, where: 0 = no disease symptoms, 1 = 1-10% of the crop canopy showing symptoms;2 = 11-25% showing symptoms, 3 = 26- 50% showing symptoms, and 4 = > 50% showing symptoms. Photographs of affected plants were taken and sent to plant pathologists across Western Canada for their opinions on causation. Where possible, representative samples of plants with disease symptoms were packaged and sent to the Alberta Plant Health Lab (APHL) in Edmonton, AB for diagnostic analyses. Background information, such as the general cultural practices and cropping history, was obtained from the producers wherever possible. GPS coordinates were obtained for each field to enable future mapping Cereals: Individual fields of barley (11 ha) and wheat (30 ha) located at Farm #1 were surveyed. The barley was a two-row forage cultivar 'CDC Maverick', while the wheat was an unspecified cultivar of Canada Prairie Spring (CPS) Wheat. Plant samples were taken along a W-shaped transect for a total of five sampling points for the barley field (< 20 ha) and ten sampling points for the wheat field (> 20 ha). The first visit, which occurred on July 30, involved visual inspection and destructive sampling wherein plants were collected and removed from the field for a detailed disease assessment at a lab space in Whitehorse. There, the roots were rinsed off and the plants were examined for disease symptoms. The second visit to these fields, which occurred on August 27, only involved visual examination of the standing crop. Oilseeds: A single 40 ha field of Polish canola (cv. 'Synergy') was examined o

ABSTRACT
Edible vaccines are created from transgenic plants and animals and contain immunostimulant. Edible vaccines, to put it simply, are medications generated from plants or animals. In underdeveloped countries, oral vaccines are less expensive and more widely available. Researchers came up with the idea of edible vaccines, in which edible plant pieces are employed as a vaccine factory. To make edible vaccinations, scientists put desired genes into plants and then force the plants to generate the proteins expressed in the genes. Transgenic plants are the result of transformation, whereas transformation is the act of converting plants. The edible vaccination promotes mucosal immunity. Dendritic cells in the gut can assist native T cells activate and differentiate into follicular T-helpers (Tfh). T and B cells will respond precisely to a reliable, digestible immunization. Potato, tomato, banana, carrots, tobacco, papaya, algae, and a variety of other plants are utilised as alternative agents for standard vaccinations. Malaria, cholera, hepatitis, rabies, measles, rotavirus, diarrhoea cancer treatments and treatment of covid-19 are among the illnesses for which plant-based vaccines have been created. It takes time and dedication to develop and sell edible vaccinations. Many edible vaccines for animal and human ailments have been developed and have gone through various levels of clinical testing. The importance of plant-based vaccinations is emphasized in this article.
ABSTRACT
The COVID-19 pandemic presented many challenges for the LSU AgCenter 4-H program. To meet social distancing guidelines and ensure the safety of youth and agents, many of programming efforts transitioned to a virtual format. However, the need remained for hands-on learning opportunities. 4-H programming is driven by the motto "learn by doing", and it was paramount that agents provide purposeful and engaging activities. The 4-H Seed-of-the-Month Club is a project club that emerged to meet that need. Agents created a nine-month seed subscription made available to youth across the region beginning in August 2020. With this project, participating youth were provided seeds of various plants, including pine seedlings, rainbow carrots, easter egg radishes, lettuce, green beans, okra, squash and coneflowers. Agents used the LSU AgCenter Louisiana planting guide to select the seeds to offer each month. In the future, agents and youth alike have expressed an interest in continuing to provide horticulture opportunities through the delivery mode of the Seed-of-the-Month Club. Participants were asked to provide top choices for their gardens by receiving carrots, lettuce and green bean seeds for the future.

ABSTRACT
Covid-19, which started in China and affected all countries in the world in a short time, spread rapidly among people and caused serious loss of life. This global epidemic has not only been effective on human health, but has also brought with it a new world order in economic and social terms. In Turkey, the impact of the epidemic reached critical dimensions in time, especially in the health sector, as well as in the agriculture and industry sectors. The aim of this research is to comparatively evaluate consumer preferences for agricultural and food products before and during Covid-19. The material of the research consists of data obtained from 384 consumers residing in the urban area of Samsun. Research results in the epidemic process;expiry date, price, brand, It shows that the ranking of the most important criteria related to agricultural and food products such as production date and company name has not changed compared to the pre-epidemic period, but the importance of the criteria has increased. According to the results of the research, the highest consumption increase was in garlic with 57.1% compared to the pre-epidemic period, followed by bulgur (45.8%) and carrots (42.3%). It was determined that the most effective factors in purchasing agricultural and food products during the epidemic were price reductions (49.7%) and experience with the purchased product (28.1%). The fact that price reductions are taken into account when purchasing agricultural and food products shows that economic concerns are still a determining criterion for consumers during the epidemic process. however, it shows that the importance of the criteria has increased.

ABSTRACT
The essential and fatty oils were investigated and a quantitative analysis of the root, green and stem parts of F. Longipedunculata was performed by GC-MS and HPLC-TOF/MS and their antioxidant (DPPH method) activities and potential binding of phytochemicals against SARS-CoV-2 nucleocapsid were determined using Molegro Virtual Docker software. In the root part of the plant, the prominent components of oil were beta-phellandrene (53.46%), ocimene (6.79%), 4-terpineol (5.94%) and santalol (5.03%). According to the quantitative results, vanillic acid (141.35 mg/kg), ferulic acid (126.19 mg/kg) and 4-hydroxybenzoic acid (119.92 mg/kg) were found in the roots;quercetin-3-beta-O-glycoside (1737.70 mg/kg), quercetin (531.35 mg/kg) and ferulic acid (246.22 mg/kg) were found in the in the green part;and fumaric acid (2100.21 mg/kg), quercetin-3-beta-O-glycoside (163.24 mg/kg), vanillic acid (57.59 mg/kg) were detected in the stem part. The antioxidant activity of all parts of the plant was higher than the control with BHT. Silibinin, rutin, and neohesperidin exhibited a stronger affinity than nucleotides. In the silico analysis, many of the phytochemicals were attached with strong hydrogen-bonds and electrostatic effects to the amino acids to which nucleotides are bound. The results indicated that the plant showed antioxidant effects and can be effective against SARS-CoV-2 thanks to the different phytochemical compounds it contains.
ABSTRACT
Covid-19, the first case of which was reported in Wuhan (China) in December 2019 was found to be a strain of coronaviruses like SARS and MERS reported earlier. These viruses are positive strain RNA viruses composed of both structural as well as non-structural proteins. The enzyme RdRp (RNA dependent RNA polymerase) stands responsible for catalyzing the replication of this virus within the host cell. A disruption in the core catalytic subunit composed of nsp12, nsp7, and nsp8 may inhibit the replication of the same. Different drugs targeting different sites on the virus have been developed. In this context, some of the natural products of the plant Centella asiatica was lead for further drug development against the target proteins of RdRp protein (PDB ID: 6NUR) through molecular docking. These compounds are 2,3-dihydroxyurs-12-en-28-oic acid, corosolic acid and pomolic acid which are triterpenoids and have highest binding affinity against RdRp protein thereby arresting the viral replication. Several previous studies showed triterpenoids as pertinent mediators implicated in the in vitro immune response.
