Lung cancer continues to be the leading cause of cancer-related death worldwide. In the last decade, significant advancements in the diagnosis and treatment of lung cancer, particularly NSCLC, have been achieved with the help of molecular translational research. Among the hopeful breakthroughs in therapeutic approaches, advances in targeted therapy have brought the most successful outcomes in NSCLC treatment. In targeted therapy, antagonists target the specific genes, proteins, or the microenvironment of tumors supporting cancer growth and survival. Indeed, cancer can be managed by blocking the target genes related to tumor cell progression without causing noticeable damage to normal cells. Currently, efforts have been focused on improving the targeted therapy aspects regarding the encouraging outcomes in cancer treatment and the quality of life of patients. Treatment with targeted therapy for NSCLC is changing rapidly due to the pace of scientific research. Accordingly, this updated study aimed to discuss the tumor target antigens comprehensively and targeted therapy-related agents in NSCLC. The current study also summarized the available clinical trial studies for NSCLC patients.
Background
Coronavirus 2019 (COVID 19) has been reported as a pandemic by the world health organization. Increasing number of cases and associated mortality have demanded the need for clinical studies and researches.
Objective
The aim of this study is to evaluate intubation prognosis of the COVID 19 patients referred to Shahid Beheshti hospital in Qom city.
Method
COVID 19 patients referred to (XXX)were included in this study. Clinical sign and symptoms were recorded for each patient in a questionnaire. The diagnosis was made using real time polymerase chain reaction and chest CT scans. Lab findings from renal and liver function tests, blood count, c-reactive protein and electrolytes were also recorded. Shortness of breath was measured using oxygen saturation levels in these patients. The data was recorded in the electronic form and was analyzed using SPSS v21.
Result
Of 317 patients included in this study, the average age of COVID 19 patients were 59.71±16.46 years. The need of ventilation among the patients older than 50 years was significantly higher than younger patients, p=0.013. Smoking status, gender and drug addiction was not associated with the need of invasive mechanical ventilation, p=0.73, p=0.44 and p=0.76. Patients need invasive mechanical ventilation compared to those receiving non-invasive ventilation were significantly older, p=0.001.
Conclusion
The need of mechanical ventilation is significantly greater in advanced age COVID-19 patients.
Background:Influenza H1N1 is very important worldwide and point mutations that occur in the virus gene are a threat for the World Health Organization (WHO) and druggists, since they could make this virus resistant to the existing antibiotics. Influenza epidemics cause severe respiratory illness in 30 to 50 million people and kill 250,000 to 500,000 people worldwide every year. Nowadays, drug design is not done through trial and error because of its cost and waste of time; therefore bioinformatics studies is essential for designing drugs.Materials and Methods:This paper, infolds a study on binding site of Neuraminidase (NA) enzyme, (that is very important in drug design) in 310K temperature and different dielectrics, for the best drug design. Information of NA enzyme was extracted from Protein Data Bank (PDB) and National Center for Biotechnology Information (NCBI) websites. The new sequences of N1 were downloaded from the NCBI influenza virus sequence database. Drug binding sites were assimilated and homologized modeling using Argus lab 4.0, HyperChem 6.0 and Chem. D3 softwares. Their stability was assessed in different dielectrics and temperatures.Result:Measurements of potential energy (Kcal/mol) of binding sites of NA in different dielectrics and 310K temperature revealed that at time step size = 0 pSec drug binding sites have maximum energy level and at time step size = 100 pSec have maximum stability and minimum energy.Conclusions:Drug binding sites are more dependent on dielectric constants rather than on temperature and the optimum dielectric constant is 39/78.
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.
