Organic As

Abstract The inputs of As in forest ecosystems have declined since the eighties when the higher concentrations of that metalloid were observed due to industrial activities. The As inputs to the forest floor include throughfall and litterfall where dry deposition is an appreciable percentage. This is manifested by the higher As concentration in older needles of conifers and the enrichment of throughfall relative to the bulk deposition. The throughfall and the forest floor convert the inorganic As into methylated organic As and in this way reduce its toxicity. In unpolluted forests the vast percentage of As is retained in soils because the oxides of Fe and Al are very efficient holders. In polluted forested soils the As can become mobile and enrich the surface runoff waters approaching even the threshold value set by the World Health Organization. For this reason forest soils with high concentration of As due to former high loads should be monitored.

Rural areas have been facing distinctive challenges during the COVID-19 pandemic. As in other parts of the world, in the Republic of Serbia noticed movement of people from places with high concentration of settlements, like cities, into less densely populated communities. Searching for rural, natural, wild areas far away from cities, tourists made different pressures on local environment (sound, litter, pressure on natural resources, pollution) but also increased demands for healthier way of living in accordance with World Health Organization recommendation during the Covid 19 period. Besides a clear environment, they would like to enjoy locally produced food and wild edible plants as a source of minerals, vitamins and other functional substances for strengthening immunity. Using standard botanical questionnaire, the research was conducted in selected rural areas with the aim to create a list of the most wanted wild edible plants by tourists and to overview their potential contribution to immune system strengthening in the COVID-19 pandemic period.

It has been almost two years since COVID-19, a disease caused by a new coronavirus called SARS-CoV-2, was declared a pandemic by the World Health Organization. The entire scientific and medical community was put to the test during the following months to find the best therapeutic strategy to save lives. Although some antivirals and anti-inflammatory drugs are being tested in different clinical trials with some controversial results, this short review will focus on corticosteroids usefulness and ventilatory support principles, as they have become two essential therapeutic pillars for those patients who need hospital admission due to respiratory failure.

AbstractOn 26 November 2021, the World Health Organization designated the SARS-CoV-2 variant B.1.1.529, Omicron, a variant of concern. However, the phylogenetic and evolutionary dynamics of this variant remain unclear. An analysis of the 131 Omicron variant sequences from November 9 to November 28, 2021 reveals that variants have diverged into at least 6 major subgroups. 86.3% of the cases have an insertion at amino acid 214 (INS214EPE) of the spike protein. Neutrality analysis of DH (−2.814, p<0.001) and Zeng’s E (0.0583, p=1.0) tests suggested that directional selection was the major driving force of Omicron variant evolution. The synonymous (Dsyn) and nonsynonymous (Dnonsyn) polymorphisms of the Omicron variant spike gene were estimated with Tajima’s D statistic to eliminate homogenous effects. Both D ratio (Dnonsyn/Dsyn, 1.57) and ΔD (Dsyn-Dnonsyn, 0.63) indicate that purifying selection operates at present. The low nucleotide diversity (0.00008) and Tajima D value (−2.709, p<0.001) also confirms that Omicron variants had already spread in human population for more than the 6 weeks than has been reported. These results, along with our previous analysis of Delta and Lambda variants, also supports the validity of the Tajima’s D test score, with a threshold value as −2.50, as an accurate predictor of new COVID-19 outbreaks.

The World Health Organization (WHO) declared COVID-19 as a public health epidemic emergency of international concern in March 2020. In just two years, this pandemic has invaded most countries and killed more than 4,800,000. The evolution of the number of cases and contaminations per day remains alarming. In May 2021, the bar of 400,000 new cases was crossed in India; this represents the highest daily number of cases recorded by a country in the history of the COVID-19 pandemic. In addition, new variants of the virus emerged in some countries. The international scientific and political community has organized itself and engaged in a race against time to find possible remedies. During this period, when people were forced to confine themselves to their homes, the way of life changed remarkably. From the declaration of the pandemic to the conception of the first vaccine, people are still in shock. This article is a short-review that explains in general what the COVID-19; the origin, biology and genetics as well as the mode of transmission and contamination of the coronavirus are discussed.

Around the end of December 2019, a new beta-coronavirus from Wuhan City, Hubei Province, China began to spread rapidly. The new virus, called SARS-CoV-2, which could be transmitted through respiratory droplets, had a range of mild to severe symptoms, from simple cold in some cases to death in others. The disease caused by SARS-CoV-2 was named COVID-19 by WHO and has so far killed more people than SARS and MERS. Following the widespread global outbreak of COVID-19, with more than 132758 confirmed cases and 4955 deaths worldwide, the World Health Organization declared COVID-19 a pandemic disease in January 2020. Earlier studies on viral pneumonia epidemics has shown that pregnant women are at greater risk than others. During pregnancy, the pregnant woman is more prone to infectious diseases. Research on both SARS-CoV and MERS-CoV, which are pathologically similar to SARS-CoV-2, has shown that being infected with these viruses during pregnancy increases the risk of maternal death, stillbirth, intrauterine growth retardation and, preterm delivery. With the exponential increase in cases of COVID-19 throughout the world, there is a need to understand the effects of SARS-CoV-2 on the health of pregnant women, through extrapolation of earlier studies that have been conducted on pregnant women infected with SARS-CoV, and MERS-CoV. There is an urgent need to understand the chance of vertical transmission of SARS-CoV-2 from mother to fetus and the possibility of the virus crossing the placental barrier. Additionally, since some viral diseases and antiviral drugs may have a negative impact on the mother and fetus, in which case, pregnant women need special attention for the prevention, diagnosis, and treatment of COVID-19.

Corona Virus Disease (Covid-19) is a contagious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) which was discovered in December 2019 in China. This disease can cause clinical manifestations in the airway, lung and systemic. The World Health Organization (WHO) representative of China reported a pneumonia case with unknown etiology in Wuhan City, Hubei Province, China on December 31, 2019. The cause was identified as a new type of coronavirus on January 7, 2020 with an estimated source of the virus from traditional markets (seafood market). ) Wuhan city
