The outbreak of severe acute respiratory syndrome coronavirus 2(sARs-CoV-2) has marked the beginning of a new pandemic named coronavirus disease 2019(COVID-19). The World Health Organization has announced it as a health emergency that is of international concern. The disease has been reported to cause respiratory illness, pneumonia and even hinder the immunity of an individual. Individuals with disturbed immune responses have been found to be quite susceptible to this viral infection. Oral cancer patients are also at high risk in this pandemic situation and might encounter severe detrimental outcomes. Angiotensin receptors, documented in studies as the path of entry of this virus, are highly expressed in the epithelial cells of oral mucosa, making the group of individuals with oral cancers even more vulnerable. Extracellular matrix metalloproteinase inducer is another potential target for sARs-CoV-2. An exhaustion of angiotensin converting enzyme 2 cell receptors leads to protumoral effects, whereas a downregulation of extracellular matrix metalloproteinase inducer leads to antitumoral effects. Thus, it causes a variation of the biological behavior of the tumor. This article focusses on the molecular mechanisms, effects and pathophysiology of COVID-19 in oral squamous cell carcinoma patients. The different molecular changes in oral squamous cell carcinoma in the background of COVID-19 will modify various environmental factors for this pathology and have an effect on the carcinogenesis process. Understanding the behavior of the tumor will help plan advanced treatment strategies for oral squamous cell carcinoma patients in the background of COVID-19.

在1989年8月14日，伊利诺斯州芝加哥市库克郡巡回法院宣布1979年加利·多特森（Gary Dotson）强奸案件的判决无效，并撤销了定罪裁决。多特森先生在监狱中服刑达10年之久，后来得到了假释，他并不是美国历史上第一个被无罪释放的无辜的囚犯。但是，该案是美国刑事司法历史上的一个转折点：他是第一个受益于DNA鉴定技术而被无罪释放的罪犯。该案掀开了美国刑事司法系统改革的帷幕。在此前，针对被错误定罪的被告作出无罪释放的裁决被视为是反常的情况。但是自从1989年以来，这种少有的事变成了一种令人不安的常见的情况。

The objective of this work is to optimize input parameters of AWJM (Abrasive Water Jet Machining) such as Nozzle Transverse speed (NTs), Abrasive Flow Rate (AFR) and stand-off Distance (sOD) using three different abrasives Garnet, Brown Fused Alumina and White Aluminum Oxide on Ms2062 and to compare their performance with surface finish, MRR and kerf angle. Experiments were conducted according to Taguchi’s design of experiments. Analysis of variance is conducted to investigate the influence of each parameter on responses Three controllable parameters of three levels are applied for determining the optimal responses The results revealed that NTs is a most significant factor for MRR among three abrasives followed by AFR and sOD, with regards to surface finish and MRR White Aluminum Oxide has emerged as a most strong abrasive followed by Brown Fused Alumina and Garnet. It is recommended, to achieve the better surface finish, less kerf angle and good MRR White Aluminum Oxide be used in place of Garnet which is mostly used by the industry today.
