The world is currently faced with a very serious crisis to deal with the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2 or Covid-19) pandemic which started in Wuhan, China in December 2019 and has since spread throughout the world, wreaking havoc in many countries. Several efforts are being made to control the spread of the disease around the world and to find a cure or vaccine. As researchers frantically endeavor to identify remedies for covid19, there is the need to identify therapies that offer the quickest, safest actions and remedies that are relatively cheap. We propose the use of aerosolized inhalation antibody conjugated nanoparticles for the treatment of covid-19. It is hypothesized in this proposal that the conjugation of nanoparticles with antibodies and delivering the antibody-nanoparticle conjugate as an aerosol via the respiratory tract would provide the quickest and possibly more efficient and relatively cheap remedy against covid-19. The advantage of the inhalation route for delivering antibody conjugated nanoparticles is that since the medication is delivered directly to the affected site, higher doses will be delivered to the site with reduced systemic toxicity and reduced adverse effects on gaseous exchange. Our hypothesis is based on the current knowledge and observations in the areas of monoclonal antibody technology, advances in nanotechnology and Nano medicine as well as advances in inhalation therapeutics.

Background: Coronavirus disease 2019 (COVID-19) is a new strain of coronavirus. It is characterized by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has quickly influenced all over the world since it spreads easily. Common symptoms are fever, cough, difficulty in breathing and muscle aches. Despite the urgent need to find an effective antiviral treatment, already available agents are being used alone or in combination all over the world. At the beginning of the pandemic, death rates of infection caused by COVID-19 are high but "is COVID-19 responsible for all deaths?", or “are there any contributions of the frequently used drugs in this period to these deaths?” Surely herd immunity plays a major role and has the contribution in the decline in mortality rates. Meanwhile, it is kept in mind that due to safety concerns, changes have also been made to the dosage and combined use of frequently used drugs. Objective: In this review, answers to two questions above and the safety of treatments, toxicities of agents involving chloroquine, hydroxychloroquine, remdesivir, favipiravir, lopiravir/ritonavir, sarilumab, tocilizumab, siltuximab, corticosteroids and bromhexine which are the most frequently used in both Turkey and all over the world will be summarized. Conclusion: Among these drugs favipiravir seems the most promising drug due to more tolerable adverse effects. More clinical trials with large sample sizes are needed to find the most effective and safe drug for COVID-19 treatment.

Since December 2019, a pneumonia outbreak with unknown etiology occurred in Wuhan, China. Later, the pathogen was identified as novel human coronavirus and named as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The disease was named corona virus disease 2019 (COVID-19) and caused a pandemic. As of 23 June 2020, the global COVID-19 pandemic has battered the world. More than 1.5 million people have died with over 80 million people confirmed infected. This outbreak is spreading in approximately 216 countries and regions as of 22 July 2020. Comparing the three human coronavirus, SARS and MERS have significantly higher case fatality rates than COVID-19, but COVID-19 is more infectious and spreads more easily among people. Therefore, in this chapter, the authors summarize the most fatal pandemic in recorded history. Also, they collected all information about the current knowledge about COVID-19 pandemic including similarity and differences with other human coronaviruses.

A novel, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes severe acute respiratory syndrome and spread globally from Wuhan, China. In March 2020 the World Health Organization declared the SARS-Cov-2 virus as a COVID- 19, a global pandemic. This pandemic happened to be followed by some restrictions, and specially lockdown playing the leading role for the people to get disassociated with their personal and social schedules. And now the food is the most necessary thing to take care of. It seems the new challenge for the individual is self-isolation to maintain themselves on the health basis and fight against the pandemic situation by boosting their immunity. Food organised by proper diet may maintain the physical and mental health of the individual. Ayurveda aims to promote and preserve the health, strength and the longevity of the healthy person and to cure the disease by properly channelling with and without Ahara. In Ayurveda, diet (Ahara) is considered as one of the critical pillars of life, and Langhana plays an important role too. This article will review the relevance of dietetic approach described in Ayurveda with and without food (Asthavidhi visheshaytana & Lanhgan) during COVID-19 like a pandemic.

The world is currently going through a disastrous event and a catastrophic upheaval caused by the coronavirus disease 2019 (COVID-19). The pandemic has resulted in loss of more than 150000 deaths across the globe. Originating from China and spreading across all continents within a short span of time, it has become a matter of international emergency. Different agencies are adopting diverse approaches to stop and spread of this viral disease but still now nothing confirmatory has come up. Due to lack of vaccines and proper therapeutic drugs, the disease is still spreading like wild fire without control. An Old but very promising method- the convalescent plasma therapy could be the key therapy to stop this pandemic. This method has already proven its mettle on several occasions previously and has been found to be effective in curing the pandemics induced by Ebola, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the same group of β-Coronavirus that has resulted in the above diseases. Therefore, the role of plasma therapy is being explored for treatment of this disease. In this review, we have mainly focused on the role of convalescent plasma therapy and why its use should be promoted in fight against COVID-19, as it could turn out to be a game changer.

AbstractCyanobacteria are important members of lake plankton, but they have the ability to form blooms and produce cyanotoxins and thus cause a number of adverse effects. Freshwater ecosystems around the world have been investigated for the distribution of cyanobacteria and their toxins and the effects they have on the ecosystems. Similar research was performed on the Fehérvárcsurgó reservoir in Hungary during 2018. Cyanobacteria were present and blooming, and the highest abundance was recorded in July (2,822,000 cells/mL). The species present were Aphanizomenon flos-aquae, Microcystis flos-aquae, Microcystis wesenbergii, Cuspidothrix issatschenkoi, Dolichospermum flos-aquae, and Snowella litoralis. In July and September, the microcystin encoding gene mcyE and the saxitoxin encoding gene sxtG were amplified in the biomass samples. While a low concentration of microcystin-RR was found in one water sample from July, analyses of Abramis brama and Carassius gibelio caught from the reservoir did not show the presence of the investigated microcystins in the fish tissue. However, several histopathological changes, predominantly in gills and kidneys, were observed in the fish, and the damage was more severe during May and especially July, which coincides with the increase in cyanobacterial biomass during the summer months. Cyanobacteria may thus have adverse effects in this ecosystem.

An outbreak of “Pneumonia of Unknown Etiology” occurred in Wuhan, China, in late December 2019. Later, the agent factor was identified and coined as SARS-CoV-2, and the disease was named coronavirus disease 2019 (COVID-19). In a shorter period, this newly emergent infection brought the world to a standstill. On 11 March 2020, the WHO declared COVID-19 as a pandemic. Researchers across the globe have joined their hands to investigate SARS-CoV-2 in terms of pathogenicity, transmissibility, and deduce therapeutics to subjugate this infection. The researchers and scholars practicing different arts of medicine are on an extensive quest to come up with safer ways to curb the pathological implications of this viral infection. A huge number of clinical trials are underway from the branch of allopathy and naturopathy. Besides, a paradigm shift on cellular therapy and nano-medicine protocols has to be optimized for better clinical and functional outcomes of COVID-19-affected individuals. This article unveils a comprehensive review of the pathogenesis mode of spread, and various treatment modalities to combat COVID-19 disease.

Deeper understanding of the spread, morbidity, fatality, and development of immune response associated with coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, is necessary in order to establish an appropriate epidemiological and clinical response. Exposure control represents a key part of the combat against COVID-19, as the effectiveness of current therapeutic options remains partial. Since the preventive measures have not been sufficiently able to slow down this pandemic, in this article we explore some of the pertinent knowledge gaps, while overall looking to effective vaccination strategies as a way out. Early on, such strategies may need to rely on counting the convalescents as protected in order to speed up the immunization of the whole population.

The Mimosa genus belongs to the Fabaceae family of legumes and consists of about 400 species distributed all over the world. The growth forms of plants belonging to the Mimosa genus range from herbs to trees. Several species of this genus play important roles in folk medicine. In this review, we aimed to present the current knowledge of the ethnogeographical distribution, ethnotraditional uses, nutritional values, pharmaceutical potential, and toxicity of the genus Mimosa to facilitate the exploitation of its therapeutic potential for the treatment of human ailments. The present paper consists of a systematic overview of the scientific literature relating to the genus Mimosa published between 1931 and 2020, which was achieved by consulting various databases (Science Direct, Francis and Taylor, Scopus, Google Scholar, PubMed, SciELO, Web of Science, SciFinder, Wiley, Springer, Google, The Plant Database). More than 160 research articles were included in this review regarding the Mimosa genus. Mimosa species are nutritionally very important and several species are used as feed for different varieties of chickens. Studies regarding their biological potential have shown that species of the Mimosa genus have promising pharmacological properties, including antimicrobial, antioxidant, anticancer, antidiabetic, wound-healing, hypolipidemic, anti-inflammatory, hepatoprotective, antinociceptive, antiepileptic, neuropharmacological, toxicological, antiallergic, antihyperurisemic, larvicidal, antiparasitic, molluscicidal, antimutagenic, genotoxic, teratogenic, antispasmolytic, antiviral, and antivenom activities. The findings regarding the genus Mimosa suggest that this genus could be the future of the medicinal industry for the treatment of various diseases, although in the future more research should be carried out to explore its ethnopharmacological, toxicological, and nutritional attributes.

AbstractThe structure of exports from Australia to China reveals the dominance of primary products with the structure of imports from this country reflecting the over-reliance on manufacturing goods. This has restrained and led to fluctuations in the balance of trade surplus in Australia thereby leading to lower than otherwise and more volatile output and employment growth. The pattern of trade between Australia and China is representative of trade between Australia and the rest of the world thereby magnifying these adverse effects. Strategic trade policy has the potential to alleviate these negative effects on output and employment growth in Australia.
