Diseases of the cardiovascular system are one of the major causes of death *** diseases could be quickly detected by changes in the sound created by the action of the *** dynamic auscultations need extensive professional knowledge and emphasis on listening *** is also an unmet requirement for a compact cardiac condition early warning *** this paper,we propose a prototype of a digital stethoscopic system for the diagnosis of cardiac abnormalities in real time using machine learning *** system consists of three subsystems that interact with each other(1)a portable digital subsystem of an electronic stethoscope,(2)a decision-making subsystem,and(3)a subsystemfor displaying and visualizing the results in an understandable *** electronic stethoscope captures the patient’s phonocardiographic sounds,filters and digitizes them,and then sends the resulting phonocardiographic sounds to the decision-making *** decision-making systemclassifies sounds into normal and abnormal using machine learning techniques,and as a result identifies abnormal heart *** display and visualization subsystem demonstrates the results obtained in an understandable way not only for medical staff,but also for patients and recommends further actions to *** a result of the study,we obtained an electronic stethoscope that can diagnose cardiac abnormalities with an accuracy of more than 90%.More accurately,the proposed stethoscope can identify normal heart sounds with 93.5%accuracy,abnormal heart sounds with 93.25%***,speed is the key benefit of the proposed stethoscope as 15 s is adequate for examination.

In this research we present that Carthamus Tinctorius L.(***,otherwise known as Safflower)(Fig.1)may contain agents active in Cryptococcal infections,malaria and Leishmaniasis,as treatment options are becoming scarce due to drug resistance *** and pharmacological activities(antimicrobial,antimalarial,antileishmanial)of *** *** *** composition of volatile oil of safflower dried flowers was analyzed by gas chromatography-mass spectrophotometry with flame ionization detector(GC-FID)and in vitro sensitivity assays were performed to assess biological activity.8 known and 3 unknown compounds were detected in the extract(Fig.1).Then the Safflower ointment was manufactured and its acute toxicity study on rats was *** volatile oil of *** L exhibited activity against Cryptococcus neoformans,Plasmodium falciparum and Leishmania *** volatile oil has anticryptococcal,antimalarial and antileishmanial *** prepared ointment had an excellent acute toxicity safety profile.
