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.

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.

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.

A 61 - year-old physically fit and athletic man presented to his dermatologist with a 10 mm raised, dark lesion on the left side of his neck. A complete skin examination did not show any other abnormal areas of skin. Pathology was found consistent with Merkel cell cancer, and the patient was referred to surgery for a wide local excision and sentinel lymph node biopsy. A PET scan did not show any other areas of concern. At surgery, one of two sentinel lymph nodes was found to be involved with Merkel cell cancer and the patient received postoperative radiation.

Durum wheat (Triticum turgidum L. var. durum) is a member of the Poaceae family and tetraploid (genomes of AABB) with 28 chromosomes (2n=4x=28). Narrow genetic variability was a problem to develop genotypes with better adaptation to different agro-ecologies. Therefore, the objective of this study was to investigate the genetic variability, divergence, and path coefficient analysis of durum wheat genotypes by using morphological traits and identifying essential yield-related traits of durum wheat, and to identify promising candidate genotypes to be used in future durum wheat breeding program. The study was carried out on 81 genotypes and the experiment was laid out in a triple lattice design with an arrangement of 9 x 9 x 3 treatment, which made 243 experimental units. Results obtained on genetic variability, path coefficient, and genetic divergent analysis among yield-related traits are presented here under the present study. Generally, the present study revealed the existence of significant genetic variability among the tested genotypes for different traits helpful for direct and indirect selection.This study recommended that the potential durum wheat genotypes 214552, 208150, 238516, 5645, Mekuye, 236984, 7960, 7152, 231599, and 208242 could be used for durum wheat breeding programs for yield and yield component traits improvement under similar agro-ecologies.

Background: Posterior pericardiotomy (PP) is helpful to prevent arrhythmia; especially atrial fibrillation (AF), and cardiac tamponade postoperative cardiac valve surgery. The incidence of postoperative AF is increased due to postoperative pericardial effusion (PE). This study aimed to investigate the early outcome of PP after heart valve surgery. Methods: In this prospective study, 120 patients underwent elective valve heart surgery at our center from January 2020 until April 2022. Patients were followed up for AF and pericardial effusion, and reopening due to tamponade. Results: The mean age of patients was 35.26 years, 70.2% were female and 29.8% were male. Surgery was elective and all were valve surgery. The incidence of postoperative AF was 2%, and pericardial effusion was seen in 1% of patients. Tamponade was not seen in any case. Left PE needed intervention tube drainage of 2%. Conclusion: Posterior pericardiotomy is a simple and safe procedure during valve heart surgery, and it is effective in reducing the incidence of atrial fibrillation, pericardial effusion, and tamponade.

Objectives: This novel study explores the leadership traits held by people with substance use disorder. The purpose of this study is to help advance understanding of the positive qualities people with substance use disorder possess which can produce positive societal and organizational benefits once that person enters recovery. Additionally, this understanding can provide insight into effective treatment approaches that incorporate personal attributes that are present within active addiction. Methods: A qualitative methodology was used which included semi-structured interviews, observations, and a focus group which allowed the researcher to conduct a thematic coding analysis. The participants came from diverse backgrounds and included participants from multiple regions across the United States. Leadership was defined as having various dimensions of effective leadership that are found in both Transformational and Authentic Leadership Theories. Results: The findings revealed that people in addiction possess numerous leadership traits which position them for effective leadership and are further enhanced during their recovery journey. The top three traits which emerged from the data indicate that people in recovery from addiction are authentic, tenacious, and empathetic. Additionally, those in recovery have strong abilities to empower and inspire others and demonstrate posttraumatic growth which helps establish significant bonds of trust and commitment among followers. Conclusion: The impact of this study will change how people view addiction. Identifying the hidden treasures of leadership which are present in those struggling with addiction could illuminate recovery pathways that help identify purpose and value. This would not only advance treatment opportunities but greatly assist organizations that need strong leadership. People with substance use disorder have all the right tools to become effective leaders, and this understanding can help mitigate the stigma associated with addiction and paint it in a more positive light. 

Hoarseness of voice can occur due to anatomical or functional abnormality of the larynx, vocal cord, or recurrent laryngeal nerves. Common cause includes infections, blunt trauma, iatrogenic affection of recurrent laryngeal nerve, malignancies of thyroid, esophagus, and lung and cardio-vascular conditions such as mitral stenosis. Vocal cord paralysis due to respiratory cause is known as a pulmonary vocal syndrome.

In the 0.01 level of the two-tailed Spearman, the relationship was positive to moderate to strong relationships and the total number was n=151. The mean Spearman correlation for tests was 0.83 (range 0.973 to 0.633), for infested was 0.81 (range 0.579 to 0.973), for recovered was 0.61 (range 0.633 to 0.618), for death was 0.81 (range 0.553876 to 0.618). This research additionally showed a moderate to strong relationship between tests, infections, recoveries, and deaths of SARS-CoV-2.Conclusion: COVID-19 has spread out unexpectedly to 64 districts in Bangladesh. The persevering with the occurrence of COVID-19 infections has emphasized the significance of the short and accurate and advanced 118 laboratory diagnoses to restriction it unfolds. In this situation, human beings must keep away from public gatherings as plenty as possible and pass return home as speedy as possible after finishing work in a public place. It is safer now because the vaccine controlled the infestation and death rate of COVID-19 in Bangladesh.

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.
