    Crime and high rates of incarceration impose tremendous costs on society, with lasting negative effects on individuals, families, and communities. Rates of crime in the United States have been falling steadily, but still constitute a serious economic and social challenge. At the same time, the incarceration rate in the United States is so high -- more than 700 out of every 100,000 people are incarcerated -- that both crime scholars and policymakers alike question whether, for nonviolent criminals in particular, the social costs of incarceration exceed the social benefits

    Optical implementation of the encoding of two qubits to a single qutrit

    Full text link
    We have devised an optical scheme for the recently proposed protocol for encoding two qubits into one qutrit. In this protocol, Alice encodes an arbitrary pure product state of two qubits into a state of one qutrit. Bob can then restore error-free any of the two encoded qubit states but not both of them simultaneously. We have successfully realized this scheme experimentally using spatial-mode encoding. Each qubit (qutrit) was represented by a single photon that could propagate through two (three) separate fibers. We theoretically propose two generalizations of the original protocol. We have found a probabilistic operation that enables to retrieve both qubits simultaneously with the average fidelity above 90% and we have proposed extension of the original encoding transformation to encode N qubits into one (N+1)-dimensional system.Comment: 6 pages, 3 figures, RevTeX

    Telah dilakukan sebuah penelitian observasi, purposif dan deskriptif terhadap dokter praktik jamusecara komplementer-alternatif dengan menggunakan jamu di 9 dari 12 provinsi wilayah SentraPengembangan, Penerapan dan Pengobatan Tradisional (SP3T) di Indonesia selama 6 bulan penelitian.Didapatkan 63 pasien artritis yang yang masuk ke dalam penelitian, menerima terapi konvensionaldan tradisional. Seluruh pasien berusia ¥16 tahun, dengan persentase terbanyak pada usia 51-70tahun (50,8%). Ditemukan 37% pasien memiliki riwayat penyakit hipertensi sebelumnya, dan 7%riwayat rematoid arthritis. Sebanyak 47% pasien dengan hipertensi pada keluarga dan 16% pasiendengan rematoid arthritis pada keluarganya. Terapi konvensional terbanyak yang digunakan dalamterapi pasien arthritis yaitu golongan NSAID (43%), disusul suplemen (22%), fiioterapi (12%), antipirai(10%), kortikosteroid (4%), lain-lain (4%), dan analgetik narkotik (3%). Komponen jamu yang seringdigunakan yaitu jamu osteoarthritis Tawangmangu (37,5%), sambiloto (11,3%), temulawak (11,2%),jahe (8,1%), habbatussauda/jinten hitam (8,1%), dan murat (4,8%). Adapun keterampilan dengan alatyang digunakan yaitu akupunktur (47%), akupresur (13%), stimulasi listrik (7%), akupunktur & stimulasilistrik (7%). Perubahan pasca terapi yang terjadi adalah perbaikan, berupa hilangnya gejala penyakit.Gejala klinis yang paling banyak menghilang saat follow up yaitu gejala sistem neurologis (33%), sistemmuskuloskeletal (31%), dan tak kalah pentingnya yaitu gejala umum (23%), karena 3 dari 4 gejala umum(tidak nafsu makan, letih, dan penurunan berat badan) merupakan gejala yang paling sering ditemuipada penderita rematoid artritis. Meskipun demikian perbaikan gejala klinis ini belum bisa dipastikansemata-mata karena efek terapi jamu saja, karena selain jamu digunakan pula terapi konvensionallainnya. Ditemukan pula peningkatan Quality of Life (QoL) derajat baik sebelum terapi (36%) danmenjadi 79% pada masa sesudah terapi

    Indonesia merupakan negara dengan kekayaan flora nomor 2 di dunia, memiliki berbagai macam tumbuhan yang dapat dimanfaatkan sebagai obat termasuk untuk pengobatan kanker. Akan tetapi dalam pemakaian tumbuhan untuk pengobatan masih rendah bila dibandingkan dengan beberapa negara Asia, terutama dalam hal pemakaian tumbuhan obat yang terintegrasikan dalam pelayanan kesehatan formal. Diberbagai belahan dunia tumbuhan obat telah banyak digunakan untuk pengobatan kanker, baik sebagai pencegahan maupun pengobatan. Tanaman yang digunakan adalah yang mengandung senyawa atau substansi seperti karotenoid, vitamin C, selenium, serat dan komponen-komponennya, dithiolthiones, isotiosianat, indol, fenol, inhibitor protease, senyawa aliin, fitisterol, fitoestrogen dan limonen. Glukosianalat dan indol, tiosianat dan isotiosianat, fenol dan kumarin dapat menginduksi multiplikasi enzim fase II (melarutkan dan umumnya mengaktivasi). Asam askorbat dan fenol memblok pembentukan karsinogen seperti nitro- samine.Flavonoid dan karotenoid bertindak sebagai antioksidan. Karotenoid dan sterol mengubah struktur membran atau integritas. Senyawa yang mengandung sulfur dapat menekan DNA dan sintesis protein, sedangkan fitoestrogen bersaing dengan estradiol untuk reseptor estrogen sehingga akan terjadi keadaan anti proliperatif. Perhimpunan Dokter Indonesia Pengembang Kesehatan Tradisional Timur (PDPKT), setelah melalui prosedur dan identifikasi yang panjang, berhasil memilih 30 jenis tanaman berkhasiat obat dalam mengatasi berbagai penyakit, termasuk kanker. Selain itu berdasarkan pengalaman pengobatan di RSU Dr. Saiful Anwar Malang dan RSUD Dr. Soetomo Surabaya, diperoleh sejumlah herbal yang dapat dimanfaatkan dalam pelayanan kesehatan. Di Indonesia, prevalensi penyakit kanker cukup tinggi. Data Riset Kesehatan Dasar (Riskesdas) tahun 2007, prevalensi tumor/kanker di Indonesia adalah 4,3 per 1.000 penduduk dan merupakan penyebab kematian nomor 7 sebesar 5,7% dari seluruh penyebab kematian.4 Sementara itu pada Riskesdas tahun 2013, prevalensi tumor/kanker di Indonesia adalah 1,4 per 1000 penduduk, atau sekitar 330.000 orang. Prevalensi kanker tertinggi terdapat di DI Yogyakarta (4,1%), diikuti Jawa Tengah (2,1%), Bali (2%), Bengkulu, dan DKI Jakarta masing-masing 1,9 per mil. Penyakit kanker juga menyebabkan beban pembiayaan negara sangat tinggi. Hal ini dapat diketahui dari data Jamkesmas yang menunjukkan bahwa pemanfaatan dana Jamkesmas paling tinggi penyerapannya untuk penanganan penyakit kanker dibandingkan dengan penyakit degeneratif lainnya. pengobatan kanker yang baik harus memenuhi fungsi menyembuhkan (kuratif), mengurangi rasa sakit (paliatif) dan mencegah timbulnya kembali (preventif).6 Pengobatan komplementer alternatif adalah salah satu pelayanan kesehatan yang akhir-akhir ini banyak diminati oleh masyarakat maupun kalangan kedokteran konvensional.7 Pelayanan kesehatan tradisional komple-menter alternatif merupakan pelayanan yang menggabungkan pelayanan konven-sional dengan kesehatan tradisional dan/atau hanya sebagai alternatif menggunakan pelayanan kesehatan tradisional, terintegrasi dalam pelayanan kesehatan formal.7 Keberhasilan masuknya obat tradisional ke dalam sistem pelayanan kesehatan formal hanya dapat dicapai apabila terdapat kemajuan yang besar dari para klinisi untuk menerima dan menggunakan obat tradisional. Penyelenggaran pengobatan komple-menter alternatif diatur dalam standar pelayanan medik herbal menurut Kepmenkes No.121/Menkes/SK/II/2008 yang meliputi melakukan anamnesis; melakukan pemeriksaan meliputi pemeriksaan fisik (inspeksi, palpasi, perkusi dan auskultasi) maupun To determine the use of herbs as complementary therapy in the practice of herbal medicine doctor , performed a cross sectional study , non-intervention in patients with doctors\u27 complementary - alternative herbal medicine in hospitals , health centers, clinic of physician networks Indonesia.

    In Trypanosoma brucei and related kinetoplastid parasites, transcription of protein coding genes is largely unregulated. Rather, mRNA binding proteins, which impact processes such as transcript stability and translation efficiency, are the predominant regulators of gene expression. Arginine methylation is a posttranslational modification that preferentially targets RNA binding proteins and is, therefore, likely to have a substantial impact on T. brucei biology. The data presented here demonstrate that cells depleted of T. brucei PRMT1 (TbPRMT1), a major type I protein arginine methyltransferase, exhibit decreased virulence in an animal model. To understand the basis of this phenotype, quantitative global proteomics was employed to measure protein steady-state levels in cells lacking TbPRMT1. The approach revealed striking changes in proteins involved in energy metabolism. Most prominent were a decrease in glycolytic enzyme abundance and an increase in proline degradation pathway components, changes that resemble the metabolic remodeling that occurs during T. brucei life cycle progression. The work describes several RNA binding proteins whose association with mRNA was altered in TbPRMT1-depleted cells, and a large number of TbPRMT1-interacting proteins, thereby highlighting potential TbPRMT1 substrates. Many proteins involved in the T. brucei starvation stress response were found to interact with TbPRMT1, prompting analysis of the response of TbPRMT1-depleted cells to nutrient deprivation. Indeed, depletion of TbPRMT1 strongly hinders the ability of T. brucei to form cytoplasmic mRNA granules under starvation conditions. Finally, this work shows that TbPRMT1 itself binds nucleic acids in vitro and in vivo, a feature completely novel to protein arginine methyltransferases.IMPORTANCETrypanosoma brucei infection causes human African trypanosomiasis, also known as sleeping sickness, a disease with a nearly 100% fatality rate when untreated. Current drugs are expensive, toxic, and highly impractical to administer, prompting the community to explore various unique aspects of T. brucei biology in search of better treatments. In this study, we identified the protein arginine methyltransferase (PRMT), TbPRMT1, as a factor that modulates numerous aspects of T. brucei biology. These include glycolysis and life cycle progression signaling, both of which are being intensely researched toward identification of potential drug targets. Our data will aid research in those fields. Furthermore, we demonstrate for the first time a direct association of a PRMT with nucleic acids, a finding we believe could translate to other organisms, including humans, thereby impacting research in fields as distant as human cancer biology and immune response modulation.
