Background: Post-acute sequelae of SARS-CoV-2 infection (PASC) is a complicated disease that affects millions of people all over the world. Previous studies have shown that PASC impacts 10% of SARS-CoV-2 infected patients of which 50–70% are hospitalised. It has also been shown that 10–12% of those vaccinated against COVID-19 were affected by PASC and its complications. The severity and the later development of PASC symptoms are positively associated with the early intensity of the infection. Results: The generated health complications caused by PASC involve a vast variety of organ systems. Patients affected by PASC have been diagnosed with neuropsychiatric and neurological symptoms. The cardiovascular system also has been involved and several diseases such as myocarditis, pericarditis, and coronary artery diseases were reported. Chronic hematological problems such as thrombotic endothelialitis and hypercoagulability were described as conditions that could increase the risk of clotting disorders and coagulopathy in PASC patients. Chest pain, breathlessness, and cough in PASC patients were associated with the respiratory system in long-COVID causing respiratory distress syndrome. The observed immune complications were notable, involving several diseases. The renal system also was impacted, which resulted in raising the risk of diseases such as thrombotic issues, fibrosis, and sepsis. Endocrine gland malfunction can lead to diabetes, thyroiditis, and male infertility. Symptoms such as diarrhea, nausea, loss of appetite, and taste were also among reported observations due to several gastrointestinal disorders. Skin abnormalities might be an indication of infection and long-term implications such as persistent cutaneous complaints linked to PASC. Conclusions: Long-COVID is a multidimensional syndrome with considerable public health implications, affecting several physiological systems and demanding thorough medical therapy, and more study to address its underlying causes and long-term effects is needed.

COVID-19 is an illness caused by severe acute respiratory syndrome coronavirus 2. Due to its rapid spread, in March 2020 the World Health Organization (WHO) declared pandemic. Since the outbreak of pandemic many governments, scientists, and institutions started to work on new vaccines and finding of new and repurposing drugs. Drug repurposing is an excellent option for discovery of already used drugs, effective against COVID-19, lowering the cost of production, and shortening the period of delivery, especially when preclinical safety studies have already been performed. There are many approved drugs that showed significant results against COVID-19, like ivermectin and hydrochloroquine, including alternative treatment options against COVID-19, utilizing herbal medicine. This article summarized 11 repurposing drugs, their positive and negative health implications, along with traditional herbal alternatives, that harvest strong potential in efficient treatments options against COVID-19, with small or no significant side effects. Out of 11 repurposing drugs, four drugs are in status of emergency approval, most of them being in phase IV clinical trials. The first repurposing drug approved for clinical usage is remdesivir, whereas chloroquine and hydrochloroquine approval for emergency use was revoked by FDA for COVID-19 treatment in June 2020.

The five most common cultivars from the genus Allium cepa L. in Bosnia and Herzegovina (BiH) were analysed, focusing on Konjic onion. Seven SSR markers for genetic similarity analysis were used to address the genetic backgrounds. The polymorphic relationship between the SSR markers was analyzed by using Polymorphic Information Content (PIC) and Heterozygosity (H) by using the online available PICcalc program. For the complete data analysis and phylogenetic tree construction, the DARwin 6.0.13 software was used. The total number of obtained SSR alleles was 30 bands, where 56.7% were polymorphic with the range of allele size of 130 to 650 base pairs (bp). The mean polymorphic information content (PIC) was 0.435 and the expected heterozygosity (H) values ranged from 0 to 0.785. Jaccard's coefficient of similarity values ranged from 0.14 to 0.55. The results in this study represent the first genetic diversity data on the onion cultivars in BiH and show significant dissimilarity among the onion cultivars. This study confirmed that the molecular SSR analysis represents an efficient tool for Allium cepa L. landrace genetic similarity analysis.

Among numerous causative agents recognized as oncogenic drivers, 13% of total cancer cases occur as a result of viral infections. The intricacy and diversity of carcinogenic processes, however, raise significant concerns about the mechanistic function of viruses in cancer. All tumor-associated viruses have been shown to encode viral oncogenes with a potential for cell transformation and the development of malignancies, including diffuse large B-cell lymphoma (DLBCL). Given the difficulties in identifying single mechanistic explanations, it is necessary to combine ideas from systems biology and viral evolution to comprehend the processes driving viral cancer. The potential for more efficient and acceptable therapies lies in targeted medicines that aim at viral proteins or trigger immune responses to either avoid infection or eliminate infected or cancerous cells. In this review, we aim to describe the role of viral infections and their mechanistic approaches in DLBCL tumorigenesis. To the best of our knowledge, this is the first review summarizing the oncogenic potential of numerous viral agents in DLBCL development.

Background: Metal-nicotianamine transporter (YSL) family protein belongs to the oligopeptide heavy metal transporter group, as characterized in Arabidopsis thaliana . Oligopeptide transporters (OPTs) are a group of membrane-localized proteins, involved in different transport mechanisms, contributing to nitrogen mobilization, glutathione transport and long-distance metal distribution. Metal-nicotianamine transporter gene 3 (YSL3) incorporates the oligopeptide transporter domain, found to transfer several heavy metals in diverse plant species, and among them cadmium transport in Brassica oleracea . Objective: To evaluate and confirm the expression of Metal-nicotianamine transporter (YSL3) under cadmium stress. Studied species: Brassica oleracea var. acephala Study site and dates: Brassica oleracea var. acephala samples were collected from Blagaj region, Bosnia and Herzegovina. Methods: Through a simple bioinformatic approach the interactome partner of Metal-nicotianamine transporter (YSL3) was discovered and annotated. Oligopeptide transporter 3 (OPT3) and Metal-nicotianamine transporter (YSL3) genes were checked for expression levels under cadmium stress. Results: We have identified a strong interacting partner of YSL3, later confirmed as Oligopeptide transporter 3 (OPT3) protein in Brassica oleracea . The in vitro expression analysis by using a qRT-PCR revealed a significant upregulation of YSL3 and OPT3, during Cd stress. Conclusions: These findings indicate that the represented in-silico approach, followed by in vitro gene expression study, successfully confirmed YSL3 and identified OPT3 as a new gene, in correlation to cadmium stress.
