Potential Use

According to the World Health Organization, cardiovascular diseases are responsible for 31% of global deaths. A reduction in mortality can be achieved by promoting a healthy lifestyle, developing prevention strategies, and developing new therapies. Polyphenols are present in food and drinks such as tea, cocoa, fruits, berries, and vegetables. These compounds have strong antioxidative properties, which might have a cardioprotective effect. The aim of this paper is to examine the potential of polyphenols in cardioprotective use based on in vitro human and rat cardiomyocytes as well as fibroblast research. Based on the papers discussed in this review, polyphenols have the potential for cardioprotective use due to their multilevel points of action which include, among others, anti-inflammatory, antioxidant, antithrombotic, and vasodilatory. Polyphenols may have potential use in new and effective preventions or therapies for cardiovascular diseases, yet more clinical studies are needed.

The new SARS-CoV-2 belonging to the coronaviruses family has caused a pandemic affecting millions of people around the world. This pandemic has been declared by the World Health Organization as an international public health emergency. Although several clinical trials involving a large number of drugs are currently underway, no treatment protocol for COVID-19 has been officially approved so far. Here we demonstrate through a search in the scientific literature that the traditional Moroccan pharmacopoeia, which includes more than 500 medicinal plants, is a fascinating and promising source for the research of natural molecules active against SARS-CoV-2. Multiple in-silico and in-vitro studies showed that some of the medicinal plants used by Moroccans for centuries possess inhibitory activity against SARS-CoV or SARS-CoV-2. These inhibitory activities are achieved through the different molecular mechanisms of virus penetration and replication, or indirectly through stimulation of immunity. Thus, the potential of plants, plant extracts and molecules derived from plants that are traditionally used in Morocco and have activity against SARS-CoV-2, could be explored in the search for a preventive or curative treatment against COVID-19. Furthermore, safe plants or plant extracts that are proven to stimulate immunity could be officially recommended by governments as nutritional supplements.

In December of 2019, an outbreak of a novel coronavirus flared in Wuhan, the capital city of the Hubei Province, China. The pathogen has been identified as a novel enveloped RNA beta-coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus SARS-CoV-2 is associated with a disease characterized by severe atypical pneumonia known as coronavirus 2019 (COVID-19). Typical symptoms of this disease include cough, fever, malaise, shortness of breath, gastrointestinal symptoms, anosmia, and, in severe cases, pneumonia.1 The high-risk group of COVID-19 patients includes people over the age of 60 years as well as people with existing cardiovascular disease and/or diabetes mellitus. Epidemiological investigations have suggested that the outbreak was associated with a live animal market in Wuhan. Within the first few months of the outbreak, cases were growing exponentially all over the world. The unabated spread of this deadly and highly infectious virus is a health emergency for all nations in the world and has led to the World Health Organization (WHO) declaring a pandemic on March 11, 2020. In this report, we consolidate and review the available clinically and preclinically relevant results emanating from in vitro animal models and clinical studies of drugs approved for emergency use as a treatment for COVID-19, including remdesivir, hydroxychloroquine, and lopinavir-ritonavir combinations. These compounds have been frequently touted as top candidates to treat COVID-19, but recent clinical reports suggest mixed outcomes on their efficacies within the current clinical protocol frameworks.

ABSTRACT Stenotrophomonas maltophilia is an emerging opportunistic pathogen, classified by the World Health Organization as one of the leading multidrug-resistant organisms in hospital settings. The need to discover novel compounds and/or combination therapies for S. maltophilia is urgent. We demonstrate the in vitro efficacy of aztreonam-avibactam (ATM-AVI) against S. maltophilia and kinetically characterize the inhibition of the L2 β-lactamase by avibactam. ATM-AVI overcomes aztreonam resistance in selected clinical strains of S. maltophilia, addressing an unmet medical need.

Cardiovascular diseases rank first on the mortality list globally or 31%. The basic measure of prevention in accordance with the recommendations of the World Health Organization is a change in risk lifestyle in terms of diet, physical activity, tobacco and alcohol consumption. Vitamin D was previously recognized as a regulator of calcium and phosphorus ratio, bone remodeling or the main controller of skeletal pathophysiology. However, vitamin D enjoys great interest in clinical and epidemiological research in terms of its possible impact on reducing the risk of cardiovascular diseases. Among other things, vitamin D deficiency is associated with an increased risk of endothelial dysfunction. Although the deficiency has been identified as a risk marker for cardiovascular diseases, the mechanism of action of vitamin D on the path from endothelial dysfunction to cardiovascular diseases has not been fully revealed. The findings in this segment of activity of vitamin D would be significant in terms of reducing morbidity and mortality from cardiovascular diseases.

The Impact

Since the enactment of the COVID-19 pandemic status by the World Health Organization (WHO) on March 11, 2020. Massive joint efforts are needed by the world community to fight the spread of the COVID 19 virus so as not to cause more victims. The crisis due to the spread of Covid 19 is not only seen as a health crisis, but affects crises in various sectors of public life, because the impact affects all sectors of life. Facing this, in addition to medical efforts by finding anti-viruses, public awareness of a healthy lifestyle is also needed, namely getting used to behavior following health protocols in carrying out various life activities to inhibit and stop the rate of transmission of Covid 19. Paying attention to the movement of the spread of Covid 19 which runs very fast Therefore, fast public awareness is also needed to get used to following the covid 19 protocol. For this reason, all levels of society must take part in increasing public awareness to carry out various activities by following the Covid 19 protocol including Higher Education, as the efforts that have been carried out by UIN Mataram through Participatory Work Lecture (KKP) activities in 2020

In December 2020, the U.K. authorities reported to the World Health Organization (WHO) that a new COVID-19 variant, considered to be a variant under investigation from December 2020 (VUI-202012/01), was identified through viral genomic sequencing. Although several other mutants were previously reported, VUI-202012/01 proved to be about 70% more transmissible. Hence, the usefulness and effectiveness of the newly U.S. Food and Drug Administration (FDA)-approved COVID-19 vaccines against these new variants are doubtfully questioned. As a result of these unexpected mutants from COVID-19 and due to lack of time, much research interest is directed toward assessing secondary metabolites as potential candidates for developing lead pharmaceuticals. In this study, a marine-derived fungus Aspergillus terreus was investigated, affording two butenolide derivatives, butyrolactones I (1) and III (2), a meroterpenoid, terretonin (3), and 4-hydroxy-3-(3-methylbut-2-enyl)benzaldehyde (4). Chemical structures were unambiguously determined based on mass spectrometry and extensive 1D/2D NMR analyses experiments. Compounds (1–4) were assessed for their in vitro anti-inflammatory, antiallergic, and in silico COVID-19 main protease (Mpro) and elastase inhibitory activities. Among the tested compounds, only 1 revealed significant activities comparable to or even more potent than respective standard drugs, which makes butyrolactone I (1) a potential lead entity for developing a new remedy to treat and/or control the currently devastating and deadly effects of COVID-19 pandemic and elastase-related inflammatory complications.

Cardiovascular diseases (CVDs) have now become the leading cause of mortality or even morbidity in India. According to the World Health Organization, cardiovascular disease causes 12 million deaths in the world each year. Even with all the advancements in medicine, the management of CVD’s are yet to be redefined. Ayurveda proposes a different understanding to etiopathogenesis of such conditions and subsequent healthcare, in the context of hrdroga. Latest researches in Ayurveda have given a new hope in CVDs, the curative as well as preventive aspects. With the emergence of increasing number of cardiac problems from the young age itself, it is the time to explore various options available in the alternative areas of medicine. Herbs and dietary supplements can have significant role in preventive cardiology as well as per published studies. Equivalent is the management of associative psychological contributors. In this article, research works of medicinal plants useful in cardiology are described with special emphasis on rasona, arjuna, guggulu, amalaki and gokshura. This work emphasises the scope of such practice so as to popularize the options available in Ayurvedic literature.
