Covid-19 Detection For CT-scan Images Using Transfer Learning Models

COVID-19 is a respiratory illness caused by a virus called SARS-CoV-2 which affected around 455 million people around the world. CT-scan is a medical imaging technique that uses X-rays to create detailed images of the body and which can be used to detect many respiratory diseases. Transfer learning models are a type of machine learning model that are trained on a large dataset of images and which can be used for their already trained ability to extract features from image in other tasks. They can then be used to classify new images with similar features.This paper presents a study of different transfer learning models for the task of classifying chest X-ray images into three classes: COVID-19, pneumonia, and normal. The study was implemented using Python and the dataset used was the COVID-19 Chest X-ray Dataset. The train-test split used was 0.2–0.8. The parameters used to test the models were the precision, recall, accuracy, F1 score, and Matthew’s correlation score. Other than these, different optimizers were also compared such as ADAM, SGD with different learning rates of 0.01, 0.001, and 0.0001.The models used in this study are EfficientNetB0, EfficientNetB7, VGG16, and InceptionV3. Out of these models, the most effective model was the EfficientNetB0 model, which achieved an accuracy of 98.6%. This study provides valuable insights into the use of transfer learning for medical image analysis. The results suggest that transfer learning can be used to develop accurate and efficient models that can be used as a secondary option for the diagnosis of COVID-19 using chest X-ray images

Review on Therapeutic Uses of Mimosa Pudica (Touch-me-not) Plant

The prostrate or semi-erect subshrub Mimosa pudica L. (Mimosacee), referred to as touch me not, live and die, shame plant, and humble plant, is indigenous to North and South America as well as Australia. They are delicate soft grey green leaves that fold and droop at night or when handled and chilled, and they are thickly equipped with recurved thorns in India. Its peculiar bending behaviors have given it the nickname "curiosity plant." According to Ayurveda, the root of this plant is bitter, acrid, cooling, vulnerary, and alexipharmic. Leprosy, dysentery, vaginal and uterine complaints, inflammations, burning sensations, asthma, leucoderma, tiredness, and blood disorders are among the conditions it is used to treat. It appears to be a prospective herbal candidate deserving of further research, as shown by its pharmacological profile Numerous illnesses, including cancer, diabetes, hepatitis, obesity, and urinary infections, are also prevented or treated using mimosa pudica. It predominantly contains pharmacological activities that include antibacterial, antivenom, antitertility, anticonvulsant, depressant, aphrodisiac, and others. The plant has been used to treat urogenital issues for ages
