Pemantauan kesehatan pasien jarak jauh untuk menjelaskan kondisi kesehatan pasien telah mendorong manusia untuk membuat sistem pemantauan kesehatan berbasis IoT (Internet Of Things). Pemantauan dirasa penting untuk pasien yang berbaring di kasur dan tidak bergerak dalam jangka waktu yang lama, karena kondisi tersebut dapat menimbulkan ulkus dekubitus. Untuk mencegah masalah tersebut digunakan matras pereduksi dekubitus yang mengubah titik tumpu pada kulit secara berkala. Ada kondisi saat matras mengalami malafungsi, dan matras tidak lagi mengubah titik tumpu pada kulit secara berkala. Untuk itu perlu adanya pemantauan tekanan kantung udara matras sehingga kondisi tersebut bisa diatasi. Raspberry Pi 3 menjalankan simulasi perubahan siklus tekanan kantung udara pada matras secara periodik. Data simulasi tersebut akan dikirimkan ke server menggunakan modul GPS/GPRS SIM868 dan akan disimpan dalam database. Lokasi alat dapat diketahui dengan menggunakan modul GPS yang terintegrasi dalam modul GPS/GPRS SIM868. Dalam halaman web ditampilkan simulasi kembang kempis kantung udara matras yang diindikasikan dengan warna. Modul GPS/GPRS SIM868 dapat berkomunikasi dengan Raspberry Pi dan dapat mengirimkan data simulasi perubahan siklus tekanan udara pada matras. Pengujian tampilan halaman web dengan siklus simulasi kembang kempis kantung udara dengan indikasi perubahan warna pada matras sudah sesuai dengan data simulasi tekanan kantung udara yang dikirimkan dari Raspberry Pi ke database.

Kasus penculikan anak selalu meningkat dari tahun ke tahun berdasarkan sumber dari Komisi Perlindungan Anak Indonesia (KPAI). Kasus ini juga pernah menjadi isu nasional di beberapa media masa. Banyak sekali faktor penyebab kasus ini bisa terjadi. Selain itu beberapa cara pencegahan telah disarankan dan digunakan dalam mengantisipasi terjadinya tindakan penculikan anak. Namun dari beberapa cara pencegahan yang telah disarankan masih terkendala oleh jarak dan waktu. Salah satunya bagaimana orang tua dapat memantau posisi lokasi anak pada satu waktu tertentu. Hal ini pasti sangat sulit dilakukan kalau tanpa menggunakan teknologi. Oleh karena itu penulis tertarik melakukan penelitian untuk menghasilkan satu rancangan alat pelacak lokasi anak yang dapat mengantisipasi penculikan anak. Alat pelacak lokasi ini dirancang dengan menggunakan beberapa komponen yaitu arduino, GPS dan GPRS modul, SIM card, smartphone android dan aplikasi google maps yang dirancang sedemikian rupa menjadi alat pelacak yang dapat memberikan informasi lokasi. Informasi lokasi ini dapat dilihat oleh orang tua melalui perangkat smartphone android dengan aplikasi google maps. Sehingga orang tua dapat memantau kapan saja lokasi anak mereka dengan mudah sehingga dapat menghemat waktu, jarak dan biaya. Ada beberapa tahapan yang digunakan untuk menghasilkan alat pelacak lokasi ini dapat bekerja dengan baik yaitu persiapan perangkat keras dan lunak yang dibutuhkan, perancangan rangkaian perangkat keras, pembuatan kode program sesuai rancangan rangkaian dan pengujian perangkat keras dan lunak.

We have studied glycosylation patterns in glycoprotein hormones (GPHs) and glycoprotein hormone receptor (GPHR) extracellular domains (ECD) from different species to identify areas not glycosylated that could be involved in intermolecular or intramolecular interactions. Comparative models of the structure of the TSHR ECD in complex with TSH and in complex with TSHR autoantibodies (M22, stimulating and K1-70, blocking) were obtained based on the crystal structures of the FSH-FSHR ECD, M22-TSHR leucine-rich repeat domain (LRD) and K1-70-TSHR LRD complexes. The glycosylation sites of the GPHRs and GPHs from all species studied were mapped on the model of the human TSH TSHR ECD complex. The areas on the surfaces of GPHs that are known to interact with their receptors are not glycosylated and two areas free from glycosylation, not involved in currently known interactions, have been identified. The concave faces of GPHRs leucine-rich repeats 3–7 are free from glycosylation, consistent with known interactions with the hormones. In addition, four other non-glycosylated areas have been identified, two located on the receptors’ convex surfaces, one in the long loop of the hinge regions and one at the C-terminus of the extracellular domains. Experimental evidence suggests that the non-glycosylated areas identified on the hormones and receptors are likely to be involved in forming intramolecular or intermolecular interactions.

ABSTRACT The filamentous fungus Aspergillus fumigatus normally grows on compost or hay but is also able to colonize environments such as the human lung. In order to survive, this organism needs to react to a multitude of external stimuli. Although extensive work has been carried out to investigate intracellular signal transduction in A. fumigatus, little is known about the specific stimuli and the corresponding receptors activating these signaling cascades. Here, two putative G-protein-coupled receptors, GprC and GprD, were characterized with respect to their cellular functions. Deletion of the corresponding genes resulted in drastic growth defects as hyphal extension was reduced, germination was retarded, and hyphae showed elevated levels of branching. The growth defect was found to be temperature dependent. The higher the temperature the more pronounced was the growth defect. Furthermore, compared with the wild type, the sensitivity of the mutant strains toward environmental stress caused by reactive oxygen intermediates was increased and the mutants displayed an attenuation of virulence in a murine infection model. Both mutants, especially the ΔgprC strain, exhibited increased tolerance toward cyclosporine, an inhibitor of the calcineurin signal transduction pathway. Transcriptome analyses indicated that in both the gprC and gprD deletion mutants, transcripts of primary metabolism genes were less abundant, whereas transcription of several secondary metabolism gene clusters was upregulated. Taken together, our data suggest the receptors are involved in integrating and processing stress signals via modulation of the calcineurin pathway.

Nowadays with the evolution of Internet of Things (IoT), building a network of sensors for measuring data from remote locations requires a good plan considering a lot of parameters including power consumption. A Lot of communication technologies such as WIFI, Bluetooth, Zigbee, Lora, Sigfox, and GSM/GPRS are being used based on the application and this application will have some requirements such as communication range, power consumption, and detail about data to be transmitted. In some places, especially the hilly area like Rwanda and where GSM connectivity is already covered, GSM/GPRS may be the best choice for IoT applications. Energy consumption is a big challenge in sensor nodes which are specially supplied by batteries as the lifetime of the node and network depends on the state of charge of the battery. In this paper, we are focusing on static sensor nodes communicating using the GPRS protocol. We acquired current consumption for the sensor node in different locations with their corresponding received signal quality and we tried to experimentally find a mathematical data-driven model for estimating the GSM/GPRS sensor node battery lifetime using the received signal strength indicator (RSSI). This research outcome will help to predict GPRS sensor node life, replacement intervals, and dynamic handover which will in turn provide uninterrupted data service. This model can be deployed in various remote WSN and IoT based applications like forests, volcano, etc. Our research has shown convincing results like when there is a reduction of −30 dBm in RSSI, the current consumption of the radio unit of the node will double.

GPR6 is an orphan G protein-coupled receptor that has been associated with the cannabinoid family because of its recognition of a sub-set of cannabinoid ligands. The high abundance of GPR6 in the central nervous system, along with high constitutive activity and a link to several neurodegenerative diseases make GPR6 a promising biological target. In fact, diverse research groups have demonstrated that GPR6 represents a possible target for the treatment of neurodegenerative disorders such as Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease. Several patents have claimed the use of a wide range of pyrazine derivatives as GPR6 inverse agonists for the treatment of Parkinson’s disease symptoms and other dyskinesia syndromes. However, the full pharmacological importance of GPR6 has not yet been fully explored due to the lack of high potency, readily available ligands targeting GPR6. The long-term goal of the present study is to develop such ligands. In this paper, we describe our initial steps towards this goal. A human GPR6 homology model was constructed using a suite of computational techniques. This model permitted the identification of unique GPR6 structural features and the exploration of the GPR6 binding crevice. A subset of patented pyrazine analogs were docked in the resultant GPR6 inactive state model to validate the model, rationalize the structure-activity relationships from the reported patents and identify the key residues in the binding crevice for ligand recognition. We will take this structural knowledge into the next phase of GPR6 project, in which scaffold hopping will be used to design new GPR6 ligands.
