Abstract

Many important applications are available for nonlinear reaction-diffusion equation especially in the area of biology and engineering. Therefore a mathematical model for Lie symmetry reduction of system of nonlinear reaction-diffusion equation with respect to one-dimensional Algebra is carried out in this work. Some classes of analytical and numerical solutions are obtained and expressed using suitable graphs., Comment: 7 pages, 2 figures

General Medicine
Abstract

Originating from China in 2019, the novel Coronavirus Disease 2019 (COVID-19) pandemic had badly affected most of the world causing immense morbidity and mortality. The disease in moderate to severe cases was characterized by intense inflammation leading to ARDS and hypercoagulable states leading to thrombo-embolism and mortality. Aim: This study aimed to explore the association of inflammatory biomarkers with COVID-19 disease severity in our hospital which became a dedicated COVID hospital during the pandemic.

34. Inverse Method-Based Kinetic Modelling and Process Optimization of Reverse-Phase Chromatography for Molnupiravir Synthesis.

Abstract

Our research addresses the shift towards continuous manufacturing in the pharmaceutical industry, focusing on optimizing chromatographic separation for the synthesis of molnupiravir. Using an inverse method with six different inlet concentrations for a single objective function, we systematically evaluated the adsorption of key intermediates, i.e., hydroxylamine and isobutyrate, in an isocratic solvent, determining the relevant isotherm constants. The study systematically evaluates the effects of operational variables, including flowrate, column geometry, dispersivity coefficient, and injection volume, on chromatographic performance. Findings reveal that specific operational adjustments, such as reducing flowrates or altering column dimensions, significantly influence retention times and peak profiles, thus potentially impacting the efficiency of molnupiravir production. Utilizing the inverse method, we efficiently determined equilibrium isotherms by integrating a nonlinear chromatography model and adjusting isotherm parameters to match the observed band profiles. Our research offers critical insights into optimizing chromatographic separation performance through precise operational control, leveraging computational tools for rapid and adaptable drug development.

Abstract

Introduction: Corona virus disease 2019 (COVID-19) spread rapidly across the world with very high human to human transmission rate. It spread all over the world with approximately 66.4 crore cases, 64.40 crore recoveries and 67.1 lakh deaths till now. In India there were 4.46 crore cases of which 4.41 crore recovered and there were 5.30 lakh deaths till now (CSSE COVID-19 Data)1. Aims and objective: To study the Clinical, Radiological profile and inflammatory markers in Covid-19 patients Materials and method: The study was carried out in the Department of Respiratory Medicine of R.D. Gardi Medical College, Ujjain (MP). Result: A total of 107 patients with COVID-19 disease were evaluated, the patients had a median age of 52 years and a mean age of 50.79±16.81 years. The most common clinical presentation were the fever which was seen in 80(74.8%) cases, breathlessness in 84(78.5%), cough in 71(66.4%), weakness in 27.1%, loss of smell in 31.8% and loss of taste in 29.9%. The most common co-morbidity present in the study group was diabetes mellitus, which was present in 51(47.7%) cases. The chest radiograph of the patients revealed consolidation in 51(47.7%), GGOs in 29(27.1%), GGO with consolidation in 3(2.8%) and 23(21.5%) cases had normal pattern. Severity of disease was significantly associated with age of the patient. The typical findings of chest CT in the case of COVID-19 pneumonia include "bilateral, peripheral, and basal predominant ground-glass opacities with or without consolidation and broncho-vascular thickening, In addition, atypical findings are "cavitations, central upper lobe predominance, nodules, masses, tree-in bud sign and lymphadenopathy. A significant statistical correlation was found between CT severity score. In our study, out of 107 cases, 80.4% had raised CRP level, 69.2% had raised D-dimer level, 67.3% cases had raised LDH level and 55.1% had raised S.Ferritin level. Conclusions: Chest imaging played a very important part in the diagnosis and management of covid 19 patients during the pandemic. The typical presentation of chest radiographs and HRCT thorax helped in diagnosing cases even when the RTPCR, Rapid antigen tests were negative or not available along with clinical features and inflammatory markers especially the CRP, LDH, D-dimer and S.Ferritin.
