Penerapan Internet Of Things Untuk Memantau Aktivitas Jantung Berbasis Android

The monitoring system of the heart's electrical activity is the basis of the electrocardiograph (ECG) in monitoring the condition of the heart, the ECG series consists of biopotential amplifiers from an ECG instrument which is the main component in this study, recording cardiac activity is still a burden for the medical world in the use and results of the expected output. From the results of research conducted on the heart rate graph (BPM) at the Medan Health Facility Security Center, the results of research were obtained using the MPS450 multiparameter simulator, where when changes were made to the signal gradually changes in values at 60, 80, 100, 120, 150, 180, 200, 220 had a distance change in time in sending and receiving data displayed on the android monitor screen (LCD). The results issued by android are graphic displays that can be saved in the form of images in JPEG format periodically or real time so as to facilitate and reduce the use o

Uji Daya Hambat Ekstrak Daun Lidah Mertua (Sansevieriae Trifasciata Folium) Terhadap Pertumbuhan Bakteri Escherichia Coli Dan Streptococcus SP

: Mother in law\u27s tongue plant has some active compounds inter alia saponin, polyphenol, and flavonoid that have antibacterial effects. This study aimed to identify whether the antibacterial effects of mother in law\u27s tongue leaf (Sansevieria Trifasciata) towards the growth of Escherichia coli and Streptococcus sp. This was an experimental laboratory study. The concentrations of mother in law\u27s tongue leaf extract were tested with well methods, as follows: 5%, 10%, 20%, and 40%. The results showed that this extract at concentration of 5%, 10%, 20%, and 40% could inhibit the growth of E. coli with the average diameters of inhibition zones as follows: 7.8 mm, 13 mm, 14.5 mm, and 17.3 mm meanwhile of Streptococcus sp. with the average diameters of inhibition zones, as follows: 4.6 mm, 9.6 mm, 13 mm, and 15.3 mm. Conclusion: Ethanol extract of mother in law\u27s tongue leaves (Sansevieria Trifasciata) has antibacterial activities against the growth of E. coli and Streptococcus sp. The higher the concentration is, the broader the inhibition zone is

Isolasi Bakteri Resisten Merkuri Pada Urin Pasien Dengan Tumpatan Amalgam Di Puskesmas Paniki Bawah

: Mercury is one of the most toxic heavy metals. Although it can be harmful for human health, the use of mercury in daily life virtually covers all aspects of human life, including its use as the material for dental amalgam fillings. The mercury in amalgam may enter the body, be absorbed by the digestive tract, and then be excreted through the urine. There are bacteria known to be resistant to mercury. This stduy was aimed to obtain and identify the mercury-resistant bacteria in the urine of patients with amalgam fillings. This was a descriptive-explorative study using urine samples of 2 patients who had used amalgam fillings for at least 6 months at Puskesmas (primary health care) Paniki Bawah. The samples underwent morphology, physiology, and biochemistry tests at the Microbiology Laboratory of Pharmacy FMIPA Sam Ratulangi University. The results showd that there were 3 genus of mercury resistant bacteria that survived in 10 ppm, 20 ppm, and 40 ppm concentrations of mercury, as follows: Bacillus, Klebsiella, and Staphylococcus. Conclusion: There are 3 genus of mercury resistant bacteria in the urine of patients with amalgam dental fillings

Spatial beam self-cleaning in second-harmonic generation

We experimentally demonstrate the spatial self-cleaning of a highly multimode optical beam, in the process of second-harmonic generation in a quadratic nonlinear potassium titanyl phosphate crystal. As the beam energy grows larger, the output beam from the crystal evolves from a highly speckled intensity pattern into a single, bell-shaped spot, sitting on a low energy background. We demonstrate that quadratic beam cleanup is accompanied by significant self-focusing of the fundamental beam, for both positive and negative signs of the linear phase mismatch close to the phase-matching condition

Sexual Functioning and Opioid Maintenance Treatment in Women. Results From a Large Multicentre Study

Opioid maintenance treatment (OMT) is the most widespread therapy for both females and males opioid addicts. While many studies have evaluated the OMT impact on men’s sexuality, the data collected about the change in women’s sexual functioning is still limited despite the fact that it is now well-known that opioids - both endogenous and exogenous - affect the endocrine system and play an important role in sexual functioning. The present study aims to determine how OMT with buprenorphine (BUP) or methadone (MTD) affects sexual health in women; examining also any possible emerging correlation between sexual dysfunction (SD), type of opioid and patients’ mental health. This multi-center study case recruited 258 female volunteers attending Italian public Addiction Outpatients Centers that were stabilized with OMT for at least 3 months. SD was assessed with the Arizona Sexual Experience Scale. The twelve-item General Health Questionnaire was used to assess participants’ mental health conditions. The results show that 56.6% of women receiving OMT for at least 3 months presented SD without significant differences between MTD e BUP groups. The majority of the subjects with SD have a poorer quality of intimate relationships and worse mental health than the average. To the best of our knowledge, the present study is the largest report on the presence of SDs in women as a side effects of MTD and BUP used in OMT. Since SDs cause difficulties in intimate relationships, lower patients’ quality of life and interfere with OMT beneficial outcomes, we recommend that women undertaking an opioid therapy have routine screening for SD and we highlight the importance to better examine opioid-endocrine interactions in future studies in order to provide alternative potential treatments such as the choice of opioid, opioid dose reduction and hormone supplementation

Spatial beam cleaning in quadratic nonlinear medium

We show experimentally that a laser beam scrambled by propagation in a short segment of multimode fiber may be cleaned by the nonlinear propagation in KTP cristal with type-II second-harmonic generation
