SARS-CoV-2, first emerged in December 2019 in Wuhan, China, and its rapid transmission led to the declaration of a pandemic by WHO. Nitric oxide is involved in SARS CoV-2 disease and its antiviral effects have prompted its use in the therapeutic management of SARS CoV-2. The effects of NO are concentration dependent. Local and controlled production of NO by the constitutive nitric oxide synthase appears beneficial, while overproduction due to inducible nitric oxide synthase may lead to cell destruction and tissue damage. The review discusses the role of nitric oxide in the pathogenesis of COVID-19 and its use as a probable therapeutic intervention preventing its progress to a more severe form.
SARS-CoV-2于2019年12月首次在中国武汉出现,其迅速传播导致世卫组织宣布大流行。一氧化氮参与SARS CoV-2疾病,其抗病毒作用促使其用于SARS CoV-2的治疗管理。一氧化氮的作用是浓度依赖性的。组成型一氧化氮合酶产生一氧化氮的局部和控制似乎是有益的,而诱导型一氧化氮合酶产生过量可能导致细胞破坏和组织损伤。本文讨论了一氧化氮在COVID-19发病机制中的作用及其作为一种可能的治疗干预措施的用途,以防止其发展为更严重的形式。

The fast and widespread spread of a novel human coronavirus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), highlights the urgent need to identify a potential drug to combat COVID-19 infection. In this letter, we investigated drug repurposing as an appealing technique that can help with drug development by repurposing existing drugs to treat illnesses apart from their initial indications. The molecular dynamics (MD) simulations using GROMACS (200ns) were carried out for Vilanterol Versus Budesonide towards COVID-19 Mpro. The results indicated that the RMSD, RMSF, Radius of gyration, and Hydrogen-bond analysis favored Vilanterol over Budesonide. Animal investigations and reliable clinical trials will eventually be required to establish the potential preventive and therapeutic effects of these drugs.
一种新型人类冠状病毒,即严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)的快速和广泛传播,突出表明迫切需要确定一种潜在的药物来对抗COVID-19感染。在这封信中,我们调查了药物再利用作为一种有吸引力的技术,可以通过重新利用现有药物来治疗疾病,而不是最初的适应症,从而帮助药物开发。采用GROMACS (200ns)进行维兰特罗与布地奈德对COVID-19 Mpro的分子动力学(MD)模拟。结果表明,RMSD、RMSF、旋转半径和氢键分析更倾向于维兰特罗而不是布地奈德。最终需要动物实验和可靠的临床试验来确定这些药物的潜在预防和治疗作用。

COVID-19: Mortality rate (in time) An Analysis of Publicly Available Data from 11 Countries to Calculate the Mortality Rate of COVID-19 COVID-19:死亡率(及时)对11个国家公开数据的分析,以计算COVID-19的死亡率
Pub Date : 2023-04-10 DOI: 10.2174/2666796704666230410123425
In December 2019, a new virus, COVID-19, initially found in China, started spreading worldwide, resulting in a severe pandemic with 82 million confirmed infections at the end of 2020 and 288 million at the end of 2021. With 5.4 million reported deaths due to COVID-19 at the end of 2021, the apparent mortality rate is 2%, but the general agreement is that the reported numbers are incomplete. An analysis was made on the publicly available COVID-19 data from eleven countries (8 in Europe, 2 in North America and 1 in Africa) to obtain a mortality rate for COVID-19. The data from these countries also contained information about hospital admissions and were partly available in graphics, allowing the data to be downloaded. The size of the population varied from 5 million (Norway) to more than 300 million (USA).Data from an investigation of Sanquin, the Dutch blood bank, and the Belgian Red Cross on the presence of antibodies for the virus in their blood donors were used to estimate the number of infected people at the start of the pandemic. This estimate was combined with the number of hospital admissions to obtain a hospitalization rate. The resulting hospitalization rates for The Netherlands and Belgium were 1.49 % and 2.23 %, respectively. The hospitalization rates were used to calculate the total number of infected people during the pandemic, but analysis showed that the calculation is only valid until June 2021.Using the Dutch and Belgian hospitalization rates, the available data from The Netherlands, Belgium and the United Kingdom showed that COVID-19 mortality rates of 1.2% at the start of the pandemic decreased to 0.4 % in the spring of 2021. The resulting cumulative mortality rate in July 2021 showed agreement, within the uncertainty, for Germany, France, Switzerland, USA, Canada and South Africa, but with dependence on the use of the hospitalization rate. The mortality rate was below the uncertainty band in smaller countries like Denmark and Norway.
2019年12月,一种最初在中国发现的新型病毒COVID-19开始在全球传播,导致一场严重的大流行,到2020年底确诊病例达到8200万,到2021年底确诊病例达到2.88亿。截至2021年底,报告的COVID-19死亡人数为540万人,表观死亡率为2%,但普遍认为报告的数字不完整。对11个国家(欧洲8个、北美2个和非洲1个)公开获得的COVID-19数据进行了分析,以获得COVID-19的死亡率。来自这些国家的数据还包含有关住院情况的信息,部分以图表形式提供,允许下载这些数据。人口规模从500万(挪威)到3亿多(美国)不等。荷兰血库Sanquin和比利时红十字会对献血者体内是否存在病毒抗体的调查数据被用来估计大流行开始时的感染人数。这一估计数与住院人数相结合,得出住院率。结果,荷兰和比利时的住院率分别为1.49%和2.23%。住院率被用来计算大流行期间的感染总人数,但分析显示,该计算只适用于2021年6月。利用荷兰和比利时的住院率,荷兰、比利时和英国的现有数据显示,2019冠状病毒病死亡率在大流行开始时为1.2%,到2021年春季降至0.4%。由此得出的2021年7月累积死亡率在不确定性范围内与德国、法国、瑞士、美国、加拿大和南非一致,但取决于住院率的使用情况。丹麦和挪威等较小国家的死亡率低于不确定范围。

Moisturizer and COVID-19: Are We Missing a Trick? 保湿霜和COVID-19:我们错过了一个技巧吗?
Pub Date : 2023-03-30 DOI: 10.2174/2666796704666230330083413

Corona Virus Disease 2019 (COVID-19) is reported to be transmitted predominantly by respiratory droplets and fomites. The regular use of a mask can mitigate the airborne transmission of the Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2), but comprehensive prevention of the virus is possible only when the contact spread of the virus is also addressed. The recommended use of soap and hand sanitizer (alcoholic hand rub) is effective only until subsequent contact with the virus. Furthermore, regular and repeated application of these disinfectants is impractical and harmful to the skin. The damage to the outermost epidermal layers of the skin exposes the Angiotensin-converting enzyme 2 (ACE2) receptor rich keratinocytes, enhancing the scope for percutaneous transmission of virus. Moisturizers, composed of fatty acids, fatty alcohols, mineral oils, petrolatum, etc., are generally considered cosmetics used to maintain and enhance skin condition. At very low concentrations, several of these components are found to neutralize enveloped viruses, indicating their potential antiviral activity. Soaps also generally contain many of these constituents, making them effective against viruses. Petrolatum, a key component of occlusive moisturizers, is also said to enhance innate immunity. Additionally, moisturizers also alleviate inflammation and prevent skin dryness and damage. The periodic and regular application of an appropriate moisturizer on hand and palm can play a significant role in curtailing the transmission of infectious agents, including (SARS-CoV-2), and could act as an extra line of defense against microbial infections.
据报道,2019冠状病毒病(COVID-19)主要通过呼吸道飞沫和污染物传播。经常使用口罩可以减轻严重急性呼吸综合征冠状病毒-2 (SARS-CoV-2)的空气传播,但只有同时解决了病毒的接触传播,才有可能全面预防病毒。建议使用肥皂和洗手液(含酒精的洗手液)仅在随后接触病毒之前有效。此外,定期和反复使用这些消毒剂是不切实际的,对皮肤有害。对皮肤最外层表皮的损伤暴露了富含血管紧张素转换酶2 (ACE2)受体的角质形成细胞,增加了病毒经皮传播的范围。保湿霜由脂肪酸、脂肪醇、矿物油、凡士林等组成,通常被认为是用来维持和改善皮肤状况的化妆品。在非常低的浓度下,这些成分中的一些被发现可以中和包膜病毒,这表明它们具有潜在的抗病毒活性。肥皂通常也含有许多这些成分,使它们对病毒有效。凡士林,闭塞保湿霜的关键成分,据说也能增强先天免疫力。此外,保湿霜还可以缓解炎症,防止皮肤干燥和损伤。定期在手上和手掌上涂抹适当的保湿霜,可以在减少传染性病原体(包括SARS-CoV-2)的传播方面发挥重要作用,并可以作为抵御微生物感染的额外防线。

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a single-stranded and positive-sense RNA virus, is exhibiting a great degree of mutation acclimated to variable environments, posing a great threat to human life, with numerous SARS-CoV-2 variants. This review aims to analyze emerging strains of SARS-CoV-2, their mutational pattern, their impact on viral pathogenicity, and the identification of the targets for the development of vaccines and therapeutics against the virus. SARS-CoV-2 consists of four structural protein codes viz, peplomer protein (S), an envelope protein (E), nucleoprotein capsid (N), and matrix protein (M), that are involved in the ingression of the viral genome into the host cell by interacting with the host cell receptor, i.e., human angiotensin-converting enzyme 2 (ACE2) (only S protein is shown to bind to ACE-2 receptor). The review includes consequences of mutations- D614G (pre-dominant mutation), E484K, N501Y, K417N, L452R, P681H, del69/70, del157/158, Ins214EPE, and so forth, in alpha, beta, gamma, delta, omicron including other strains of SARS-CoV-2. Mutations include substitution, deletion, and insertion of amino acids in the spike glycoprotein of the SARS-CoV-2, resulting in antibody neutralization, immune escape, etc. As a consequence of modifications in the nucleotide sequence of the viral genome code pushed on by exposure to various environments, these new strains influence the pathogenicity of the virus.
严重急性呼吸综合征冠状病毒-2 (SARS-CoV-2)是一种单链正义RNA病毒,它正在表现出适应可变环境的高度突变,对人类生命构成巨大威胁,具有大量的SARS-CoV-2变体。本文旨在分析新出现的SARS-CoV-2毒株及其突变模式、对病毒致病性的影响,以及确定针对该病毒的疫苗和治疗方法的靶点。SARS-CoV-2由四种结构蛋白编码组成,即膜层蛋白(S)、包膜蛋白(E)、核蛋白衣壳(N)和基质蛋白(M),它们通过与宿主细胞受体(即人血管紧张素转换酶2 (ACE2))相互作用参与病毒基因组进入宿主细胞(只有S蛋白被显示与ACE-2受体结合)。该综述包括突变的后果- D614G(前显性突变)、E484K、N501Y、K417N、L452R、P681H、del69/70、del157/158、Ins214EPE等,包括其他SARS-CoV-2菌株的α、β、γ、δ、组粒。突变包括在SARS-CoV-2刺突糖蛋白中替换、缺失和插入氨基酸,导致抗体中和、免疫逃逸等。由于暴露在各种环境中,病毒基因组密码的核苷酸序列发生了改变,这些新毒株影响了病毒的致病性。
