Background: The role of laboratory parameters and the relationship of
them with radiology reports, CT scan and clinical outcomes in screening
of COVID-19 patients not been definitely established, but this disease
presented a major challenge in the field of clinical tests, radiology
reports, clinical outcomes that help to monitoring and treatment
COVID-19 disease. Methods: This study was performed on 340 suspected
COVID-19 patients, who presented to Chamran Hospital, Shiraz University
of Medical Sciences Shiraz, Iran from 20 February to 31 August, 2020.
Information each patient’s will be completed using a data collection
forms based on records. The evaluation of lungs involvement in CT scan
and their relationship with laboratory indicator including biochemical
and hematological factors, is the best scale for the severity and
prognosis of Covid 19 patients. Results and Conclusion: The findings of
this study indicated ALT, AST, CRP, NEU, LDH, and Urea have very good
accuracy in predicting cases with positive RT-PCR for COVID-19,
respectively. In this study we shown the correlation of clinical and
laboratory findings with CT-based quantitative score of pulmonary
involvement in COVID-19 pneumonia and attempted that our findings could
be usable to development future clinical research associated with
COVID-19 infection and show the relationship of reports CT scan and
clinical outcomes in the diagnosis and severity of patients with
COVID-19.
Although the relationship between laboratory parameters, radiology, CT scan scan and clinical outcomes has not been well evaluated so far, COVID-19 is still a good challenge for this purpose. These tests can be used to diagnose, monitor, and treat COVID-19. The study was conducted from February 20 to August 31, 2020, following the referral of 340 patients with coronavirus symptoms at Chamran Hospital, Shiraz University of Medical Sciences, Shiraz, Iran. Clinical information of each patient is obtained based on patient information forms when visiting the hospital. Comparison of the relationship between lung involvement in CT scan and laboratory indicators, including biochemical and hematological factors is a suitable and reliable comparison to identify people with Covid 19. Based on the results of this study, it was found that ALT, AST, CRP, NEU, LDH, and Urea could be a suitable diagnostic method in positive RT-PCR for COVID-19. In this study, we tried to investigate the relationship between clinical and laboratory findings with CT-based quantitative score of pulmonary involvement in COVID-19 pneumonia and as a suitable and reliable method in continuing COVID-19 pandemic and diagnosis of COVID-19 infection.
Alkaline phosphatase enzyme (ALP, ALKP, ALPase, Alk Phos) (EC 3.1.3.1) produced by plants and microbes is presumed to convert organic phosphorus into available pi, which is absorbed by plants. Considering the importance of Alkaline phosphate enzyme and the balance between its function in the development of various diseases by increasing and decreasing the enzyme level by enzyme activating and regulating compounds, including amino acids and ions, which act as coenzyme and cofactor for the enzyme Can be a major role in Disease improvement. This study aims to comparatively investigate the inhibiting effect of the three Amino Acid as well as Alanine, Leucine and valine on Alkaline phosphatase was which extracted from Sweet Lemon (Citrus limon (L.) Osbeck), Garlic (Allium sativum L.) and Onion (Allium cepa L.). In this study, Leucine, Alanine and Valine amino acids showed strong inhibitory effects 23%, 26% and 34% respectively activity of Alkaline phosphatase obtained saline extract of plants Sweet Lemon, Garlic and Onion.
Alzheimer's disease (AD) is a multifactorial disease. In addition to the precipitating of two proteins betaamyloid peptide and neurofebrillary tangles, which are the main mechanisms involved in the pathogenesis ofAD, other factors such as inflammatory mechanisms and changes in lysosomal enzymes play an important part in the pathogenesis of this disease. Increased and decreased lysosomal proteases, such as cathepsin, can lead to functional impairment and gradual death of neurons. The aim of this review was to investigate the role of cathepsins in the pathogenesis of AD. To conduct this review, relevant articles published between 2000 and 2016, and indexed in reliable databases including PubMed, Google Scholar, Scopus and Web of Science were retrieved. After reviewing the articles, 30 articles that directly addressed the subject of this review were included in final analysis. Cathepsins exacerbate intracellular conditions in neurons, by processing beta-amyloid precursor protein and converting it into amyloid beta. They also play a protective role against AD and fight it by catalyzing the decomposition of beta-amyloids and converting them into the cut out forms of the carboxyl C-terminus. In addition, the 24 kDa fragment resulting from the effect of cathepsin D on apolipoprotein E (ApoE) is the second binding to the receptor in the ApoE. This fragment may also be the cause of the pathogenicity of Apo E in AD. Identifying and explaining the mechanisms involved in the pathogenesis of AD can play a significant role in the prevention and treatment of this disease. Since cathepsins play a pivotal role in the decomposition of beta-amyloid and reduction of the risk of AD, further studies can be considered an effective approach to study AD.Journal of Medical and Biomedical Sciences (2018) 7(1), 1 - 10
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
