ABSTRACT
Background: "Long COVID" or "post-COVID conditions" describes prolonged symptoms after the acute phase of coronavirus disease 2019 (COVID-19). However, there is a paucity of published reports on its treatment. Method(s): This retrospective cohort study included adult, non-hospitalized patients with COVID-19 symptoms at least one month after the onset who had been examined at the isolation facility in Miyagi prefecture between October 2020 and September 2021. Result(s): In total, 70 patients with a median age of 46 (21-69) years were included, and 37 were women (52.9%). The median time from onset to the end of treatment was 46 (28-396) days. Thirty-eight patients (53.5%) showed improvement in all symptoms, while four (5.7%) did not recover within the study period. The symptoms at six months with high residual rates were dizziness (33.3%), fatigue (14.3%), myalgia (14.3%), abdominal discomfort (14.3%), and taste dysfunction (11.8%). For treatment of prolonged symptoms, formulae of Kampo medicine (Japanese traditional medicine) were used alone or in combination with Western medications in 76%, 66%, 53%, and 66% of patients at 1-2 months, 2-3 months, 3-6 months, and over 6 months respectively. Kampo formulae with anti-inflammatory effects were used in the early period;however, tonifying formulae and blood stasis-resolving formulae were used in the late period. Conclusion(s): Non-hospitalized patients with COVID-19 may suffer from persistent symptoms after the acute phase of infection. For the management of long COVID, a comprehensive and holistic approach is needed. Kampo medicine should be considered as a treatment option for long COVID.Copyright © 2023 The Authors.

ABSTRACT
Background & Aim: The pro-angiogenic, immunoregulatory and anti- inflammatory properties of MSCs are being exploited for the development of cellular therapies, including the treatment of graft versus host disease (GvHD), inflammatory bowel disease and COVID-19. SNBTS have developed a GMP process to bank umbilical cord MSCs (UC-MSCs) whereby we can reliably bank 100 vials of 10 million P2 UC-MSCs per cord. Each of these vials can be extensively expanded and stored for specific applications. The ultimate aim of the bank is for off-the-shelf clinical use, e.g., in GvHD or as an adjuvant therapy in Islet transplantations. Methods, Results & Conclusion(s): During process development, different basal media and supplements were screened for proliferation and MSC marker expression. Cells grown in promising media combinations were then tested for tri-lineage differentiation (identity), their chemokine/cytokine expression and T-cell inhibition (function) assessed. Medium selected for further GMP development and scale up was ultimately determined by all round performance and regulatory compliance. GMP-like UC-MSCs were shown to have immune-modulatory activity in T-cell proliferation assays at 4:1 or 16:1 ratios. Co-culture of UC-MSCs and freshly isolated leukocytes, +/- the immune activating agent LPS, show a dose dependent survival effect on leukocytes. In particular, neutrophils, which are normally very short lived in vitro demonstrated increased viability when co-cultured with UCMSCs. The survival effect was partially reproduced when UC-MSC were replaced with conditioned medium or cell lysate indicating the involvement of soluble factors. This improved neutrophil survival also correlates with results from leukocyte migration studies that demonstrate neutrophils to be the main cell type attracted to MSCs in in vitro and in vivo. Genetic modification of UC-MSC may improve their therapeutic potential. We have tested gene editing by CRISPR/Cas9 technology in primary UC-MSCS. The CXCL8 gene, highly expressed in UC-MSC, was targeted in isolates from several different donors with editing efficiencies of 78-96% observed. This translated to significant knockdown of CXCL8 protein levels in resting cells, however after stimulation levels of CXCL8 were found to be very similar in edited and non-edited UC-MSCs. This observation requires further study, but overall the results show the potential to generate future banks of primary UC-MSCS with genetically enhanced pro-angiogenic, immunoregulatory and/or anti-inflammatory activities.Copyright © 2023 International Society for Cell & Gene Therapy
ABSTRACT
Coronavirus disease is a serious viral infection that is characterized by severe inflammation and lymphopenia. The virus attacks many organs causing acute respiratory distress and malfunctioning of the organs leading to death. Through strengthening of the innate immune system, a balanced diet plays a critical role in defense against bacterial and viral diseases. A healthy diet before, during and after an infection can lessen the severity of the symptoms and speed up the recovery of damaged cells. Due to the Mediterranean diet's high concentration of bioactive polyphenols, which have antioxidant, anti-inflammatory, and antithrombic properties, numerous studies have suggested that it is a preventative dietary strategy against many diseases including coronavirus disease. Nutrition and herbal plants play a key role to enhance the immunity of people to protect and fight against coronavirus. Diet rich in antioxidants and phytochemicals represents perfect barrier to the virus through elevation of the innate immunity of the body. In addition, gut microbiota including prebiotics, probiotics, and synbiotics were found to enhance immunity to reduce the symptoms of the disease during infection. Protein-rich foods and honey bee products reported significant role during and post-coronavirus infection. This review presents updated information from original pre-clinical and clinical researches, and review articles as well to expose the nutritive strategies including breastfeeding benefits to infants pre-infection, during, and post-infection with coronavirus.Copyright © 2023, Scientific Foundation SPIROSKI.

ABSTRACT
Pulmonary aspergillosis (PA) is a category of respiratory illnesses that significantly impacts the lives of immunocompromised individuals. However, new classifications of secondary infections like influenza associated aspergillosis (IAA) and COVID-19 associated pulmonary aspergillosis (CAPA) only exacerbate matters by expanding the demographic beyond the immunocompromised. Meanwhile anti-fungal resistant strains of Aspergillus are causing current treatments to act less effectively. Symptoms can range from mild (difficulty breathing, and expectoration of blood) to severe (multi organ failure, and neurological disease). Millions are affected yearly, and mortality rates range from 20-90% making it imperative to develop novel medicines to curtail this evolving group of diseases. Chalcones and imidazoles are current antifungal pharmacophores used to treat PA. Chalcones are a group of plant-derived flavonoids that have a variety of pharmacological effects, such as, antibacterial, anticancer, antimicrobial, and anti-inflammatory activities. Imidazoles are another class of drug that possess antibacterial, antiprotozoal, and anthelmintic activities. The increase in antifungal resistant Aspergillus and Candida species make it imperative for us to synthesize novel pharmacophores for therapeutic use. Our objective was to synthesize a chalcone and imidazole into a single pharmacophore and to evaluate its effectiveness against three different fungi from the Aspergillus or Candida species. The chalcones were synthesized via the Claisen-Schmidt aldol condensation of 4-(1H-Imizadol-1-yl) benzaldehyde with various substituted acetophenones using aqueous sodium hydroxide in methanol. The anti-fungal activity of the synthesized chalcones were evaluated via a welldiffusion assay against Aspergillus fumigatus, Aspergillus niger, and Candida albicans. The data obtained suggests that chalcone derivatives with electron-withdrawing substituents are moderately effective against Aspergillus and has the potential for further optimization as a treatment for pulmonary aspergillosis.

ABSTRACT
Background: COVID-19 is caused by SARS-CoV-2 and has is responsible for over 619 million infections and over 6.5 million deaths globally since identification in 2019. Infection during pregnancy is associated with increased adversity including increased risks of admission to intensive care, increased ventilatory support, preeclampsia, preterm birth and maternal death. Vaccination remains the best protection against severe disease. The majority of trials for novel or repurposed COVID-19 therapies including mRNA vaccinations have excluded pregnant or lactating women despite being an at-risk population. Broccoli sprout extract contains a naturally occurring phytonutrient sulforaphane which upregulates the Nrf2 transcription factor resulting in expression of antioxidant proteins, anti-inflammatory effects and has demonstrated anti-viral effects in-vitro . Severe COVID-19 results in excessive cytokine production resulting in a proinflammatory state with significant oxidative stress and multi-organ dysfunction with evidence of placental abnormalities in almost half of infected mothers. Method(s): CO-Sprout is a pilot, double blinded, placebo controlled randomised trial that is recruiting pregnant women ( n = 60) between 20 and 36 weeks completed gestation with COVID-19 diagnosed within 5 days. Participants are randomised to either broccoli sprout capsules (containing 21 mg sulforaphane) or identical placebo (microcrystalline cellulose) twice daily for 14 days. The primary outcome will be duration (days) of COVID-19 related symptoms and other exploratory outcomes including unplanned hospital admissions, birth outcomes, inflammatory markers, microbiome and placental changes. Patients are recruited through maternity departments at Monash Health and Jessie McPherson Private Hospital. Result(s): Trial in progress. Conclusion(s): Trial results to be published after trial completion.
ABSTRACT
Background: As cystic fibrosis (CF) lung disease progresses, the airways become colonized with opportunistic pathogens such as Pseudomonas aeruginosa secondary to airway surface liquid depletion. Acquisition of P. aeruginosa is associated with decline in lung function and increase in treatment burden and mortality. In October 2019, the Food and Drug Administration approved elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA), a highly effective modulator therapy (HEMT) for individuals aged 12 and older with one copy of the F508del CFTR mutation. ELX/TEZ/IVA increases the amount of and function of CF transmembrane conductance regulator (CFTR) in the respiratory epithelium, increasing mucociliary clearance (MCC) and reducing static airway mucous, a major trigger for chronic infection and inflammation. Method(s): A retrospective analysis of inhaled tobramycin (iTOB) prescriptions prescribed between January 1, 2016, and December 31, 2021, was performed. This captured data before and after ELX/TEZ/IVA approval at Children's Mercy Kansas City (CMKC). The number of individuals with new P. aeruginosa acquisition was determined by identifying electronic prescriptions for iTOB eradication courses. An eradication course was defined as a first lifetime prescription for iTOB or a new prescription for iTOB submitted at least 1 year after a previous prescription. The number of individuals considered chronically infected with P. aeruginosa was determined by identifying individuals receiving chronic iTOB prescriptions and confirmed by respiratory cultures indicating chronic infection based on the Leeds criteria (P. aeruginosa recovered in >=50% of airway cultures in the previous 12 months). Result(s): Eradication courseswere prescribed to 34 individuals in 2016 (15% of people receiving care at CMKC). The number of eradication prescriptions declined in 2020 and 2021, with only 15 (7%) individuals prescribed eradication therapy in 2020 and 12 (5%) in 2021. A similar pattern was observed for prescriptions for chronic infection. In 2016, 57 individuals (25% of our patient population) were receiving iTOB for chronic P. aeruginosa infection. Reductions were seen in 2020 and 2021, with 28 (13%) and 20 (9%) individuals prescribed chronic therapy, respectively. The number of individuals prescribed iTOB for P. aeruginosa eradication and chronic infection per year is represented in Figure 1.(Figure Presented)Conclusions: CMKC experienced a decrease in the number of courses of iTOB prescribed over the last 6 years. HEMT use is associated with greater MCC and anti-inflammatory effects affecting the airway microbiome. The decrease in respiratory cultures growing P. aeruginosa likely reflects these phenomena. A confounding factor is the SARS-CoV-2 pandemic and widespread use of HEMT. Clinic closures and implementation of telemedicine limited in-person patient visits during 2020 and 2021. Despite limited in-person visits, the average number of respiratory cultures per individual at CMKC in 2020 was 3.5, which is consistent with previous years.Wewere able to obtain frequent surveillance cultures through implementation of a drive-through respiratory specimen collection process. Hence, the decrease in number of iTOB courses cannot be attributed to a decrease in frequency of respiratory cultures, although we cannot assess the impact of school closures and a decrease in social gatherings on new P. aeruginosa acquisition or chronic infection. Looking at all these variables, the widespread use of HEMT likely played a significant role in reducing new P. aeruginosa acquisition and chronic P. aeruginosa infection.Copyright © 2022, European Cystic Fibrosis Society.

ABSTRACT
The aim of our study is analysis of the androgenic status including testosterone (T) and dihydrotestosterone (DHT) in men hospitalized with coronavirus disease 2019 (COVID-19) and them relationship with the course of the disease. This is a monocentric prospective study performed on 125 male patients hospitalized for COVID-19. We conducted hematological examination, blood biochemical profile, hemostasis analysis and hormonal examination (T and DHT levels) lung and chest computed tomography and also assessed outcomes of hospitalization. Low DHT serum level was found only in 18 patients (14.4%). Subjects with low DHT were significantly older compare to subjects with normal DHT. At the same time in patients with normal DHT white blood cells (WBC) count, neutrophils at admission were higher than in patients with low DHT. No correlation was observed between T and DHT serum blood levels. C-reactive protein (CRP) has a weak positive correlation of DHT serum blood concentration (r = 0.22;p = 0.016). The inverse pattern was obtained for T serum blood concentration (r = -0.285;p = 0.001). After divided all males according to T concentrations we conducted next correlation analysis for DHT and CRP in two different groups: with normal T levels and with low T levels. We found that in males with normal T DHT levels are not correlated with CRP (r = 0.095;p = 0.462). However, in males with low T DHT and CRP had weak positive correlation with r = 0.317 (p = 0.012). Higher DHT concentrations are associated with higher CRP levels, however correlation is weak and in patients with normal T is absent, that may indicate anti-inflammatory effect of T and possible proinflammatory effect of DHT.Copyright © 2023 The Author(s).
ABSTRACT
Naringin is a flavonoid isolated from different citrus fruits like Grapefruit, Orange, Pomelo, Lemon, etc, which are commonly called local fruit. Naringin is found in the white spongy portion of citrus peel. Its content varies from 0.65 mg/gm in the mandarin peel to 14.40mg/gm in the grapefruit peel. Naringin is metabolized to the flavanone naringenin by the enzyme Naringinase present in the liver. It can be analyzed by using various analytical techniques such as HPLC, TLC, UV, HPTLC, mass spectroscopy, Liquid chromatography, chiral chromatography and LC/Mass spectroscopy. Naringin can act as an antioxidant and scavenge free radicals. Naringin mainly focuses on in-vitro and in-vivo animal studies showing its beneficial effects on cardioprotective, antioxidant, anti-inflammatory, antimicrobial, hypolipemiant, neurological, thermogenic, pulmonary disorders and antidiabetic. Naringin is also treated as a most promising treatment strategy against Covid-19 due to its antiviral and anti-inflammatory effects. Recently, Naringin has proven its activity in various molecular docking studies. Naringin keeps the body healthy against various illnesses and major lifestyle disorders.Copyright All © 2023 are reserved by International Journal of Pharmaceutical Sciences and Research.
ABSTRACT
Historically organometallic compounds have been used to cure certain diseases with limited applications. Although bismuth belongs to the category of heavy metals, many of its derivatives have found applications in modern drug discovery research, mainly because of its low toxicity and higher bioavailability. Being an eco-friendly mild Lewis acid, compounds having bismuth as a central atom are capable of binding several proteins in humans and other species. Bismuth complexes demonstrated antibacterial potential in syphilis, diarrhea, gastritis, and colitis. Apart from antibacterial activities, bismuth compounds exhibited anticancer, antileishmanial, and some extent of antifungal and other medicinal properties. This article discusses major synthetic methods and pharmacological potentials of bismuth complexes exhibiting in vitro activity to significant clinical performance in a systematic and timely manner.Copyright © 2022 Elsevier Ltd

ABSTRACT
The article discusses the issues of terminology, epidemiology, etiopathogenesis, clinical manifestations, approaches to the diagnosis and treatment of post-covid syndrome (PCS). It has been shown that the incidence of PCS in people who had COVID-19 is 10-35%;there are no generally accepted approaches to defining the term PCS. Clinical manifestations of PCS include more than 50 symptoms that occur in both children and adults, regardless of their place of residence. The damage caused by metabolites of the systemic inflammatory response of the central nervous system with the formation of a syndrome of autonomic dysfunction, cognitive impairment, and affective disorders is of critical importance in the genesis of PCS. Antipsychotics, antidepressants, and benzodiazepine drugs are used in the correction of PCS. However, they have limitations, in particular - when used in children with comorbid disorders. The use of aminoacetic acid (glycine), which has a wide range of safety, anxiolytic, anti-inflammatory, and nootropic effects in the correction of PCS, can become an effective therapeutic strategy.Copyright © Team of Authors, 2022.
ABSTRACT
Herbal plant extracts or purified phytocomponents have been extensively used to treat several diseases since ancient times. The Indian Ayurvedic system and Chinese traditional medicines have documented the medicinal properties of important herbs. In Ayurveda, the polyherbal formulation is known to exhibit better therapeutic efficacy compared to a single herb. This review focuses on six key ayurvedic herbal plants namely, Tinospora cordifolia, Withania somnifera, Glycyrrhiza glabra/Licorice, Zingiber officinale, Emblica officinalis and Ocimum sanctum. These plants possess specific phytocomponents that aid them in fighting infections and keeping body healthy and stress-free. Plants were selected due to their reported antimicrobial and anti-inflammatory effects in several diseases and effectiveness in controlling viral pathogenesis. An ad-vanced literature search was carried out using Pubmed and google scholar. Result(s): These medicinal plants are known to exhibit several protective features against various diseases or infections. Here we have particularly emphasized on antioxidant, anti-inflammatory, anti-microbial and immunomodulatory properties which are common in these six plants. Recent literature analysis has revealed Ashwagandha to be protective for Covid-19 too. The formulation from such herbs can exhibit synergism and hence better effectiveness against infection and related dis-eases. The importance of these medicinal herbs becomes highly prominent as it maintains the har-monious balance by way of boosting the immunity in a human body. Further, greater mechanistic analyses are required to prove their efficacy in fighting infectious diseases like Covid-19. It opens the arena for in-depth research of identifying and isolating the active components from these herbs and evaluating their potency to inhibit viral infections as polyherbal formulations.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
In late 2019 until 2021, the novel coronavirus disease (COVID-19) has become pandemic. This disease is related to severe inflammatory symptoms of the respiratory epithelial cells and the dysfunction of several organs. One of the suggested drugs to reduce the inflammation caused by COVID-19 is hydroxychloroquine. Studies have shown this drug blocks the inflammatory pathway of nuclear factor-kappaB by blocking P21 activated kinase 1. Also, nanoparticle vaccines Poly Lactide-Glycolide) Acid (PLGA) containing hydroxychloroquine are effective in cancer by stimulating CD8T + cells responses. This study assumed that hydroxychloroquine was effective in inhibiting COVID-19 with these mechanisms.Copyright © 2021 Health Biotechnology And Biopharma. All Rights Reserved.
ABSTRACT
Background: Severe COVID-19 pneumonia requiring intensive care treatment remains a clinical challenge to date. Dexamethasone was reported as a promising treatment option, leading to a reduction of mortality rates in severe COVID-19 disease. However, the effect of dexamethasone treatment on cardiac injury and pulmonary embolism remains largely elusive. Method(s): In total 178 critically ill COVID-19 patients requiring intensive care treatment and mechanical ventilation were recruited in three European medical centres and included in the present retrospective study. 113 patients (63.5%) were treated with dexamethasone for a median duration of 10 days (IQR 9-10). 65 patients (36.5%) constituted the nondexamethasone control group. Result(s): While peak inflammatory markers were reduced by dexamethasone treatment, the therapy also led to a significant reduction in peak troponin levels (231% vs. 700% indicated as relative to cut off value, p=0.001). Similar, dexamethasone resulted in significantly decreased peak D-Dimer levels (2.16 mg/l vs. 6.14mg/l, p=0.002) reflected by a significant reduction in pulmonary embolism rate (4.4% vs. 20.0%, p=0.001). The antithrombotic effect of dexamethasone treatment was also evident in the presence of therapeutic anticoagulation (pulmonary embolism rate: 6% vs. 34.4%, p<0.001). Of note, no significant changes in baseline characteristics were observed between the dexamethasone and non-dexamethasone group. Conclusion(s): In severe COVID-19, antiinflammatory effects of dexamethasone treatment seem to be associated with a significant reduction in myocardial injury. Similar, a significant decrease in pulmonary embolism, independent of anticoagulation, was evident, emphasizing the beneficial effect of dexamethasone treatment in severe COVID-19.

ABSTRACT
Garlic (Allium sativum) has been known for its potent medicinal activities and its interesting culinary role since ancient times. With over 200 phytochemicals and flavoring compounds elucidated and many others yet to, garlic promises to improve human health and vitality. Just like other phytochemical classes, essential oils for garlic have been reported to show interesting medical activities delving across diverse antimicrobial, cardio-protective, anti-cancer, anti-Alzheimer, anti-diabetic, and immunomodulatory activities. Garlic essential oils contain mainly volatile and non-volatile allyl-sulphur-based compounds, which are a product of the stream decomposition of Allicin (a major component of garlic extract). Although a lot of work has been done on Allicin, there is little substantive work on the bio-availability and toxicities of its essential oil. This study, however, reviewed the methods that in recent times have been used to extract essential oils from garlic, recent studies on composition and therapeutic activities of Garlic essential oils, and a predictive overview of their bioavailability and toxicity. Finally, recommendations for future studies and other interesting prospects of garlic were also highlighted.Copyright © 2022

ABSTRACT
The Coronavirus Disease 2019 (COVID-19), also known as a novel coronavirus (2019-n-CoV), reportedly originated from Wuhan City, Hubei Province, China. Coronavirus Disease 2019 rapidly spread all over the world within a short period. On January 30, 2020, the World Health Organization (WHO) declared it a global epidemic. COVID-19 is a Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) evolves to respiratory, hepatic, gastrointestinal, and neurological complications, and eventually death. SARS-CoV and the Middle East Respiratory Syndrome coron-avirus (MERS-CoV) genome sequences similar identity with 2019-nCoV or Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). However, few amino acid sequences of 2019-nCoV differ from SARS-CoV and MERS-CoV. COVID-19 shares about 90% amino acid sequence simi-larity with SARS-CoV. Effective prevention methods should be taken in order to control this pandemic situation. To date, there are no effective treatments available to treat COVID-19. This review provides information regarding COVID-19 history, epidemiology, pathogenesis and molecular diagnosis. Also, we focus on the development of vaccines in the management of this COVID-19 pandemic and limiting the spread of the virus.Copyright © 2022 Bentham Science Publishers.
