Introduction: In the spirit of maintaining health and seeking medicine to cure a disease, the question of halal and haram still needs to be answered. This coincides with the words of the Prophet Muhammad SAW “Verily Allah does not make your healing in what He has forbidden you” (HR. Imam Bukhari). The purpose of this quantitative study was to determine the effect of religiosity, perception, knowledge, and attitudes of Muslim doctors on the use of halal drugs in Indonesia.Materials and methods: This quantitative research method with correlational type examines the relationship between religiosity, perceptions, knowledge, attitudes, intentions, and behaviors that are shared online using google form. Data was measured using a Likert scale. A five-point Likert scale was used for statements: Strongly Disagree: 1, Disagree: 2, Uncertain: 3, Agree: 4, and Strongly Agree: 5. The sample size used was 435 Muslim doctors. The data obtained were then processed using the SmartPLS 3.0 application.Results: The results obtained are that there is a relationship between the religiosity of Muslim doctors on perceptions so as to encourage intention so that there is a change in behavior in the use of halal drugs in Indonesia. In addition, there is a relationship between knowledge and attitudes so as to encourage intentions that cause behavioral changes in the use of halal drugs in Indonesia by Muslim doctors. In fact, every practice depends on the intention, therefore it is important to maintain the intention, which in this study is influenced by perceptions and attitudes so that charity will result in commendable behavior that is blessed by Allah SWT. In addition, there is also a need for education about halal drugs that are appropriate to be taught at the medical faculty of Islamic universities in Indonesia.

Background and objectives: YKL-40, a C-reactive protein belongs to the positive acute-phase protein. It is also known as Human chitinase-3-like protein 1(HCI3L1) and is closely related to both acute and chronic inflammation. The present study aimed to detect and estimate the levels of YKL-40 in gingival crevicular fluid (GCF) in patients with healthy periodontium, chronic periodontitis, and rheumatoid arthritis with chronic periodontitis. Materials and methods: Forty-five patients in the age range of 25-55years were included in the study. Patients were divided into three groups: Group I-15 Periodontal healthy patients, Group II-15 Chronic Periodontitis patients, and Group III-15 Rheumatoid arthritis with chronic periodontitis patients. Clinical parameters recorded were Plaque index, Gingival index, Gingival bleeding index, probing depth, and Relative attachment level. GCF samples were analyzed using ELISA. p - value < 0.05 was considered statistically significant. Results: The highest mean YKL-40 concentration in GCF was observed in rheumatoid arthritis with Chronic periodontitis. The mean concentration of YKL-40 in GCF showed a three to four folds increase in its levels when compared to healthy controls (p < 0.001). Contrary, GCF YKL-40 levels between Group II and Group III were not significant.Conclusion: With the increase in severity of periodontal destruction from healthy periodontium to chronic periodontitis, there was a substantial increase in the concentration of YKL-40 in GCF. Correlation of GCF YKL-40 with clinical parameters demonstrated increased severity of the diseases increased its levels

We investigated the associations between circulatory dynamics and Body Composition (BC) of the peripheral lower limbs with Exercise Habits (EHs). We surveyed the EHs of 34 healthy older adults (6 men, 28 women) and measured their BC and skin perfusion (SP). SP did not correlate significantly with any other variable. Participants with established EHs had a lower body weight and Fat Tissue thickness (Fat-T) than those without. Multiple logistic regressions with the presence or absence of an EH as the dependent variable and BC values as the independent variables established Fat-T as a significant variable. Sex was independently associated with soleus muscle thickness, Fat-T, Bone Density (BD), and leg segmental water. Age was independently associated with Fat-T and BD, and body mass index was associated with Fat-T. EHs were not independently associated with any of the BC measurements. Physical characteristics and EHs have minimal influence on peripheral circulatory dynamics.

Background: WHO and UNICEF recommend breastfeeding to be initiated within an hour of birth. However, timely initiation of breastfeeding remains low in Ethiopia. Therefore, this study aimed to compare the timely initiation of breastfeeding and associated factors with cesarean and vaginal deliveries in public hospitals in Addis Ababa, 2021. Methods and materials: Comparative cross-sectional study was conducted from January 2021 to February 2021 in public hospitals of Addis Ababa. 322 mothers within three days of delivery at the postnatal ward of the respective public hospitals were selected. A multi-stage sampling method was employed with the final participants being recruited by systematic random sampling. Data was entered to Epi data Version 4.6 and analysis was performed by SPSS Version 26. A Binary and multivariate logistic regression statistical model was used. Adjusted odds ratio with 95% CI was computed to see the strength of association. Result: Timely breastfeeding initiation was 79 (51.2%) and 123 (80%) for cesarean and vaginal deliveries. With a vaginal delivery, pre-lacteal feeding (AOR = 5.50, 95% CI: 1.83 - 16.57) was significantly associated with timely initiation of breastfeeding. Multiparity (AOR = 2.14, 95% CI: 1.02 - 4.50), support from health care workers (AOR = 2.602, 95% CI: 1.16 - 5.82), and pre-lacteal feeding (AOR = 2.55, 95% CI: 1.13 - 5.75) were significantly associated with timely initiation of breastfeeding with cesarean delivery. Conclusion: The rate of timely initiation of breastfeeding differs according to the mode of delivery. Cesarean delivery, as compared to vaginal delivery, was associated with a lower rate of timely initiation of breastfeeding.

The effect of the novel coronavirus (SARS-CoV-2) pandemic has produced significant health concerns negatively impacting individuals. As the ongoing and constantly changing nature of SARS-CoV-2 continues, the unique characteristics of this pandemic trend toward anxiety and loneliness as significant behavioral health outcomes. Furthermore, the SARS-CoV-2 pandemic has significantly impacted the utilization of social media platforms such as Twitter. Utilizing over 1.6 million tweets from approximately 988,760 Twitter users geolocated in Washington state from the University of Pennsylvania’s publicly available Twitter database (from March 2020 to March 2021), this study evaluated the impact of SARS-CoV-2 by using expressions of loneliness and anxiety to predict mental and physical symptoms. Bivariate correlations revealed expressions of loneliness were correlated to trouble breathing while expressions of anxiety were correlated to skin lesions, body aches, flu-like, seasonal cold, trouble breathing, nausea or diarrhea, fever, chills, and cough. Multiple multivariate linear regressions were completed, and a significant regression equation was found in predicting trouble breathing symptoms on expressions of loneliness and anxiety, however, the proportion of variance was 8% of the observed variation in the model. Further implications revealed the importance of understanding mental and physical well-being during a public health crisis as well as the use of social media platforms as primary and supplementary stimuli.

A literature-based review was made to assess available information on bovine hemoparasites related to their epidemiology, distribution, and economic importance in Ethiopia. Babesiosis, anaplasmosis, cowdriosis, theileriosis, and trypanosomosis are the major hemo-parasitic disease of bovine in Ethiopia. Their adverse effects on the health of the animals can decrease production and productivity. Hemoparasites generally cause fever, anemia, jaundice, anorexia, weight loss, milk drop, malaise, swelling of lymph nodes, dyspnoea, diarrhea, nervous disorders, and death by affecting blood vessels and/or lymphatic system of the animal. Reports from different parts of the country displayed there is a high distribution of bovine hemoparastic disease throughout the country. Anaplasmosis, Babesiosis (redwater), Ehlichiosis (Heartwater), Theileriosis, and Trypanosomosis are the major hemoparasitic diseases with heavy economic losses. Their mode of transmission was by arthropod vectors ticks and flies. Applying effective vector control and using vaccines drugs are the two most important control methods for hemoparasites diseases. Also having knowledge of parasite life cycles, their biological vector, and the immune response of bovines to vectors and parasites were also used in the successful application of control strategies. Creating awareness of the mode of transmission, method of control, and prevention of hemoparastic disease of bovine to livestock owners were warranted to decrease the effect of the disease.

Helminthiasis is also known as worm infection, is any macroparastic disease of humans and other animals in which a part of the body is infected with parasitic worms known as helminths. Anthelmintic agents are medicines that used for treatment and inhibition of parasitic infections caused by helminths; which involve both flat worms, such as, flukes and tapeworms and round worms, such as, nematodes. Anthelmintics are categorized into groups depending on the basis of their identical chemical structure and mode of action. Thiabendazole, mebendazole, and albendazole belong to benzimidazoles group of antihelmenthic medicines. From benzimidazoles group of antihelmenthic, thiabendazole was first discovered in 1961 and already a mentioned number of more benzamidazoles were interpolated as wide spectrum anthelmintics. Praziquantel has a particular effect on the enveloping layer of trematodes and increases permeability of calcium ion influx leading to uncontrolled muscle contraction and paralysis. Praziquantel has a particular toxic effect on schistosome parasites, where its mode of action has been resulted more extensively than in cestodes. Coadministration of mebendazole with CYP450 inhibitors medications such as cimetidine, ketoconazole and etc may be increases plasma levels of mebendazole, by extending the half-life and decreasing plasma clearance.

The study has been undertaken to investigate the determination of digital financial fraud (cyber fraud) in Jamtara district of Jharkhand (the hub of cyber fraudsters) the basic tools & techniques which are used by the offenders and to find out the socio-economic condition of their social life & find the new challenging in cybercrime investigation and to find out the more secure way of digital financial flow, by using survey research method and work on secondary as well primary data which was related to this study, cybercrime especially financial fraud becomes the new challenging task for law enforcement agencies.Digital financial frauds are being within an undefined jurisdiction so it becomes more difficult to investigate the cases and due to other different public as well private sectors of service providers like the telecom companies and the banks are unable to make the defensive system for their customer also. This is the main reason for delays in cyber-related case investigation and a very low conviction rate in cyber-related cases.

Background: Ovarian cancer (OC) is the fifth cause of cancer mortality in females. There were an estimated 300,000 new cases of OC diagnosed worldwide in 2018, corresponding to 3.4% of all cancer cases among women. The high mortality rate of OC attributed to asymptomatic growth of the tumor leads to its diagnosis at advanced stages. About 85% - 90% of OC are epithelial including serous, endometrioid, clear cell, and mucinous carcinoma. Aim: To study the immunohistochemical (IHC) expression of FOXA1 and p53 in epithelial OC and its association with prognostic indicators such as age, tumor size, stage, grade, and histological type.Materials and methods: The study included 52 cases with EOC from the pathology department, faculty of medicine, Aswan, and Sohag Universities, in the period from January 2017 to December 2019. This study involved 52 patients with OC and a median age of 53 years. Different histological types were included as 37 serous, 12 mucinous, 1 case endometroid 2 cases clear cell OC. The study cases were classified into 22 Grade I, 16 Grade II, and 20 Grade III. About 22 cases were at stage I, 9 at stage II, 11 at stage III, and 10 at stage IV. Tissue sections were stained using the IHC technique with FOX A1 at a dilution of 1:100 and p53 at 1:100. Results: A statistically significant correlation was found between FOX A1 expression and advanced patient's age, high grade, advanced stage, ruptured capsule, and ascites, regardless of tumor laterality. No significant association was found between p53 immunoexpression and the same clinic-pathological parameters although p53 was associated with serious type. Conclusion: FOXA1 immunoexpression in EOC is considered a poor prognostic factor in EOC. FOXA1 could be a potential therapeutic target and prognostic marker in EOC.

The increasing occurrence of wastewaters associated with industrial development has begotten a permanent search for new and more efficient techniques for the removal of hazardous substances such as heavy metals and dyes. The use of natural and available resources to develop improved and sustainable commodities for this purpose remains crucial and is among promising emerging green technologies for water treatment. It offers the gradual shifting of hazardous industrial chemicals precursors to the abundant non-metallic mineral resources that receive an added value. This work investigated the uptake capacity by the adsorption process of methylene blue (MB) and azocarmine G (AG) onto nano-silica synthesized from kaolinite clay. The effects of contact time (0-30 min), the adsorbent dosage (5-100 mg), the initial pH of the solution (1-11 for MB and 1-7 for AG), and the initial dye concentration (5-50 mg/L) were studied. The selected conditions to carry out kinetic and isotherm adsorption experiments were: 15 mins, 20 mg, 11 for MB, 1.01 for AG, and 50 mg/L. Four adsorption isotherms and three kinetic models were used to model the adsorption data thanks to linear and non-linear regression methods. From the obtained results, the Freundlich isotherm model fitted well the adsorption phenomenon while the pseudo-second-order kinetic model described well the adsorption mechanism. Furthermore, the free energy of adsorption was similar for the two absorbents, 0.71 kJ, pointing physisorption as the dominant adsorption mechanism. The optimum MB and AG uptake were respectively 13.8 and 36.1 mg/g. Conclusively, the nano-silica represents a potentially viable and powerful adsorbent whose use could lead to a plausible improvement in environmental preservation.

Background: Doubts about the safety of sexual activity are common among cardiac patients and physicians alike, and are often neglected during routine checkups or on discharge from the hospital following a cardiac event or invasive procedure. Although it varies from society to society, it is considered taboo by most patients, so it is reluctant to ask the doctor about sexual activity. Doctors, on the other hand, remain silent due to the lack of clear information about the effect of sexual activity on coronary artery diseases or the presence of doubts. It is ultimately set aside by professionals and their patients. The patient does not ask and the doctor does not answer. This study, it was aimed to investigate the effect of the frequency of sexual intercourse on coronary artery disease. Methods: After applying the exclusion criteria, the remaining 180 patients were included in the study. A self-administered survey was applied to the patients before coronary angiography and patients were assessed according to the presence of additional diseases, their demographic characteristics, and the frequency of sexual intercourse. Two experienced physicians evaluated the angiographic results. Firstly Patients were grouped as 90 patients with normal coronary anatomy and 90 patients with coronary artery disease. After this, Coronary artery disease severity was evaluated according to syntax score. Results: The mean age of the patients was 58 ± 12.5 years. The distribution of age is not reasonable. According to gender, the female/male ratio the proportion of men was higher in patients with coronary artery disease. İncidence of normal coronary anatomy increased as the frequency of sexual intercourse increased. P - value was 0.037 and the result was statistically significant. The frequency of sexual intercourse was found to be 4.2/per month. The relationship between the Syntax score and frequency of sexual intercourse was not statistically significant (p > 0.05).Conclusion: As a result of the study, it was seen that patients with more frequent sexual intercourse had more normal coronary artery anatomy, and those with coronary artery disease had single coronary artery disease than multiple vascular disorders. it was concluded that the incidence of coronary artery disease and coronary artery disease severity decreased as the frequency of sexual intercourse increased. Sexual intercourse might be a preventive factor in the development of coronary artery disease.

Post-Traumatic Stress Disorder (PTSD) is a disorder that affects not only military veterans but also the general public specifically children. They may replay the event and its aftermath, avoid talking about it, have low self-esteem, and be unable to develop meaningful connections. Mentally sick individuals in Pakistan frequently face an obstacle, as discussing mental health is taboo. Mentally ill people are publicly humiliated in Pakistan, and sufferers are occasionally referred to as “pagal.” Even parents ignore the symptoms of their children. 

Irbesartan (IRB) is one of the drugs used for the treatment of hypertension. The present work develops and validates two methods for the evaluation of irbesartan in bulk and tablets. Sulfonephthalein acid dyes, bromophenol blue (BPB), and bromocresol purple (BCP) were used to produce stable yellow ion-association complexes with the basic drug IRB in dry chloroform. The colored products are quantified spectrophotometrically at their corresponding λmax. The relation between the absorbed signal and the drug concentration was linear up to 45.0 μg mL-1 (n = 6, r ≥ 0.9998). LOD reaches 40 ng mL-1. The composition of the ion associates was found 1:1 by Job’s and mole ratio methods. Application of the suggested methods to dosage forms is presented with percentage recoveries ranging from 99.33% to 101.67%. The results of the analysis were validated statistically and compared with the official method. No interference was observed from common pharmaceutical adjuvants.

Today HPLC is widely applied for separations and purifications in a variety of areas including pharmaceuticals, biotechnology, environmental, polymer and food industries. It is accomplished by injection of a small amount of liquid sample into a moving stream of liquid (called the mobile phase) that passes through a column packed with particles of the stationary phase. The separation of a mixture into its components depends on different degrees of retention of each component in the column. HPLC is just one type of liquid chromatography, meaning the mobile phase is a liquid. Reversed-phase HPLC is the most common type of HPLC. The reversed-phase means the mobile phase is relatively polar, and the stationary phase is relatively non-polar. HPLC instrumentation includes a Solvent reservoir, pump, injector, column, detector, and integrator or acquisition and display system. The heart of the system is the column where separation occurs. The information that can be obtained using HPLC includes identification, quantification, and resolution of a compound. The major applications are in the area of Pharmaceuticals, food, research, manufacturing, forensics, and bio-monitoring of pollutants.

We investigated the effect of exercise therapy by simultaneously using motor imagery of thumb or all finger extension on the affected side and thumb or all finger extension exercise on the unaffected side by using the F-wave, which is used to measure the excitability of anterior horn cells to devise an appropriate exercise therapy using motor imagery for patients with increased muscle tone of the thumb muscles on the affected side. Tasks 1, 2, 3, and 4 involved motor imagery of thumb extension on the affected side, motor imagery of finger extension on the affected side, motor imagery of thumb extension on the affected side based on thumb extension on the unaffected side, and finger extension on the affected side based on finger extension on the unaffected side, respectively; conducted in three trials, with one week or more between each trial. Each task was performed for one minute, with a five-minute interval between tasks. The F-waves from the thenar muscles were recorded with median nerve stimulation on the affected side before and during the tasks. The relative values of the F-wave data of the task and the F-wave data before (resting state) and during the tasks were calculated. In results, the relative data of the F/M amplitude ratio in task 4 was lower than that in the other tasks in three trials. In conclusion, motor imagery of finger extension on the affected side with finger extension movement on the unaffected side was effective for improving the muscle tone of the thenar muscles on the affected side.

Introduction: The world is currently facing the SARS-CoV-2 pandemic with evolving 2nd wave. The COVID-19 patients present most commonly with Severe Acute Respiratory Illness (SARI) in an emergency room with acute onset fever, cough, and breathlessness. However, not all SARI cases as per definition are due to COVID-19 infection, which is well proven in this case series of 113 cases of SARI. This is just the opposite of the other SARI series done in the pre-COVID-19 era. Also, no previous SARI case series data has shown significant association with Diabetes Mellitus, including new-onset diabetes thus figuring out the major Pathophysiological association of COVID-19 with glucose metabolism and has a bearing on the pathogenesis, treatment, and outcome of COVID-19 infection and perpetuity of pandemic of this magnitude. Here we raise concern for the first time about the growing association of an infectious pandemic with the lifestyle disorders which are non-communicable diseases but carry with them the potential of fertile soil for rapidly spreading epidemics.Aim and objective: To find out the etiology, clinical profile, treatment outcome, and mortality rate in different sub-groups of SARI cases in a tertiary care hospital and the incidence of new-onset Diabetes Mellitus in them and to investigate theoretically the hypothesis that maintaining normal glucose metabolism could prevent progression of a mild Flu-like illness (FLI) to a severe form of Severe Acute Respiratory Illness (SARI) and consequent complications such as Cytokine Storm Syndrome and Multi-Organ failure.Design: Retrospective, single-center case series of 113 SARI patients at a tertiary care hospital in Agra India between 1 March- 30 October 2020.Main outcome: The demographics, clinical, pathological, imaging, and treatment outcome data were collected. The SARI cases analyzed were defined as “Severe acute respiratory infections (SARIs) an acute respiratory illness of recent onset (within seven days) manifested by fever (≥38°C), cough and shortness of breath or difficulty in breathing requiring hospitalization and were sub-classified according to the primary etiology producing SARI in them. The findings were compiled and compared. Conclusion: Of the 113 patients of SARI – 32.7 %were associated with Diabetes, with 9.74% new-onset Diabetes and 26 % previously known Diabetes. This was mainly due to SARS-CoV-2 (24 Diabetics out of 52 COVID-19 cases- 46.1 %).The Average hospitalization stay of SARI cases was 10 days with a maximum in SARS-CoV-2 and a minimum stay of 5.22 days in Bacterial Pneumonia and 5.66 days in Koch’s Lungs.The death rate was maximum (4 out of 26) 15.3%. Hospitalized TB/Koch’s Lung patients who presented as SARI and 3.8% in Bacterial Pneumonia, 2.43% in SARS-CoV-2, and <1% in Sepsis.Those SARI cases who were euglycemic at the time of initial presentation recovered early and carried a good prognosis with less mortality as compared to those who were hyperglycemic on presentation. Also, those FLI cases who maintained euglycemia or did not have any other risk factor which predisposes them to stress (Diabetes, Prolonged fasting, Obesity, major organ disorder, Psychological disorder, and Cancer) did not progress to SARI as the endogenous steroid secretion and sympathetic activation did not occur, the intracellular pH levels remained in the alkaline range.10.18% of cases developed new-onset diabetes (a total of 11 cases) out of which 10 were in COVID-19. Thus 19.2% incidence of new-onset diabetes in SARS-CoV-2 and a prevalence of 26.9% in SARS-CoV-2, making total diabetes 46.1% in SARS-CoV-2, and out of all SARI cases, 26 % of patients developed pulmonary fibrosis with consequent long-term complications. In COVID-19 patients, it was seen only in diabetics SARS CoV-2 male patients, thus no death in non-diabetic females in COVID-19 in this case series.

The SARS-CoV-2 (COVID-19) pandemic outbreak has led to some lockdowns and changed human mobility and lifestyle in this country. Mashhad, one of the most polluted cities in Iran has experienced critical air pollution conditions in recent years. In the present study, the potential relationships between air quality conditions (such as popular index and criteria air pollutant concentration) and COVID-19 cases and deaths were investigated in Mashhad, Iran. To do that, the Long Short-Term Memory (LSTM) based hybrid deep learning architecture was implemented on AQI, meteorological data (such as temperature, sea level pressure, dew points, and wind speed), traffic index and impact number of death, and active cases COVID-19 from March 2019 to March 2022 in Mashhad. The results reveal the LSTM model could predict the AQI accurately. The lower error between the real and predicted AQI, including MSE, MSLE, and MAE is 0.0153, 0.0058, and 0.1043, respectively. Also, the cosine similarity between predicted AQI and real amounts of it is 1. Moreover, in the first peak of the pandemic (Aug 2021), we have the minimum amount of AQI. Meanwhile, by increasing the number of active cases and death and by starting lockdown, because the traffic is decreased, the air quality is good and the amount of AQI related to PM2.5 is 54.68. Furthermore, the decrease the active cases and death in pandemic causes a significant increase in AQI, which is 123.52 in Nov 2021, due to a decline in lockdowns, resumption of human activities, and probable temperature inversions. 

Based on the differences between RNA and DNA, formulas for the natural frequency of torsional vibrations of single and double RNAs are obtained.It is shown that, despite the fact that millimeter waves are delayed by the skin of the human body, there are conditions under which they can freely penetrate through the human body.It is shown that centimeter waves, whose frequencies are multiples of the natural frequencies of torsional vibrations of the spirals of short DNA or RNA viruses, can cause subharmonic resonance in the spirals of RNA and DNA, which leads to the destruction of these molecules. Centimeter waves of non-thermal power flux density freely pass through the human body, which makes it possible to use them in vivo.A table has been compiled with the physical characteristics of DNA and RNA of the most dangerous viruses, indicating the frequencies of the external electromagnetic field that cause resonance in the DNA and RNA helices, which leads to the denaturation of molecules.In a series of experiments, it was shown that irradiation with microwaves with a resonant frequency of 180,402 GHz on samples with COVID-19 for 20 seconds. It has a disinfecting effect.

Objective: To establish the cephalometric norms of ‘Zero meridian line’ and ‘Mew line’ to assess the sagittal discrepancy in the maxilla and mandible of subjects in the Central Gujarat population Materials and methods: The sample was screened from the records from the hospital. 100 individuals (50 males, 50 females) of the age group between 18-50 years, native of Central Gujarat, with acceptable pleasing profile, no skeletal asymmetry, normal Class I occlusion having ideal anterior bite, less than 2 mm crowding and no history of previous orthodontic treatment were selected for the study. Lateral cephalograph were taken in natural head position. The linear measurements between points of soft tissue pogonion to the Zero Meridian line (vertical line dropped from soft tissue nasion) and distance of Mew line (the biting edge of the upper front teeth to the tip of the nose) was taken on cephalograms. Result: Mean value for soft tissue pogonion to the Zero meridian line on cephalograms was 0.2 mm for female and 0.8 mm for male and mean value for Mew line on cephalograms was 39 mm for female and 42 mm for male subjects.Conclusion: Normal value for soft tissue pogonion to the Zero meridian line is 0.8 + 1.8 mm for males and 0.2 + 1.7 mm for females, and normal value for Mew line is 41.2 + 3.2 mm for male and 39.4 + 2.2 mm for female in Central Gujarat population. Values other than normal suggests skeletal sagittal discrepancy of maxilla and/or mandible, which is helpful in diagnosis and treatment planning.

For over two years, COVID-19 pandemic has been a major global health concern and threat to human life. In the SARS-CoV2 macromolecules, the 3-chymotrypsin like protease (3CLpro or main protease) has been identified to be crucial and essential for viral survival, processing of the viral polyproteins and has been explored as a target in COVID-19 drug discovery. Although vaccines and other various inhibitors have been designed and launched, the emergence of the variant of this virus has put an unrelenting effort of researchers to this end. Also, the high cost of manufacturing these molecules coupled with the occurrence of drug resistance is a concern.Herein, Pefloxacin and its derivative for the first time were screened for their inhibitory activity against the SARS-CoV2 main protease through in silico analysis and their pharmacokinetic properties were evaluated. Interestingly, from the docking results, they both bind with high affinity at the active site of the protein. Moreover, they showed excellent pharmacokinetic and drug - likeness properties. Derivatization of Pefloxacin at the C7 position prevents its blood-brain barrier permeability. Overall, the dual antibacterial and potential antiviral activities of these two molecules make them promising drug candidates for COVID-19 management.
