Unexpected Presentation of COVID-19 in a 38-Year-Old Male Patient: A Case Report.

We presently report the case of COVID-19 in a 38-year-old male who had come to the primary health care clinic of Shahid Beheshti University of Medical Sciences, which specializes in the COVID-19 epidemic. He reported having fatigue, myalgia, fever, rash, and loss of taste and smell. The physical findings were maculopapular rash over his trunk, inguinal regions, and left arm, erythema of larynx with an aphthous lesion on left tonsil, he did not have a fever, and respiratory distress symptoms.

The Effects of Acupuncture on Hemodynamic Changes During Endotracheal Intubation for General Anesthesia.

The goal of this research was to investigate the efficacy of perioperative manual acupuncture in the LV 3 and LI 4 points for lessening hemodynamic changes during endotracheal intubation in patients who were receiving anesthesia. This double-blinded randomized controlled study enrolled patients who were undergoing endotracheal intubation, in 2015-2016, during general anesthesia in the general surgery department of the Imam Khomeini Hospital complex, in the Tehran University of Medical Sciences, Iran. The patients were randomly allocated into 2 groups with 30 patients in each group.

Design of artificial neural networks using a genetic algorithm to predict collection efficiency in venturi scrubbers.

In this study, a new approach for the auto-design of neural networks, based on a genetic algorithm (GA), has been used to predict collection efficiency in venturi scrubbers. The experimental input data, including particle diameter, throat gas velocity, liquid to gas flow rate ratio, throat hydraulic diameter, pressure drop across the venturi scrubber and collection efficiency as an output, have been used to create a GA-artificial neural network (ANN) model. The testing results from the model are in good agreement with the experimental data.
