Nitro-substituted π-electronic molecules are fascinating because of their unique electronic and optical properties and the ease of their transformation into various functional derivatives. Herein, nitro-introduced dipyrrolyldiketone BF2 complexes as anion-responsive π-electronic molecules were synthesized, and their electronic properties and anion-binding abilities were investigated by spectroscopic analyses and theoretical studies. The obtained nitro-substituted derivatives showed solvent-dependent UV/vis spectral changes and high anion-binding affinities due to the easily pyrrole-inverted conformations and polarized pyrrole NH sites upon the introduction of electron-withdrawing moieties.

SummaryIn a thrombin generation test with continuous registration of thrombin activity in plasma we studied the ability of a variety of thrombin inhibitors of different type and mechanism of action to influence the activity of thrombin after activation of the coagulation system. Depending on the inhibitor, the peak of thrombin activity is delayed and/or reduced.By blocking the active site of generated thrombin inhibitors cause a concentration dependent reduction of the thrombin peak and inhibit feed-back reactions of thrombin resulting in a delay of thrombin generation. Highly potent synthetic active-site directed inhibitors (Ki ≤ 20 nM) reduce the thrombin activity formed in plasma after extrinsic or intrinsic activation with the same efficiency (IC50 0.1 - 0.6 μM) as hirudin. The delay and reduction of thrombin generation by inhibitors of the anion-binding exosite 1 of thrombin is only attributed to an inhibition of feed-back reactions of thrombin. For a 50% reduction of thrombin activity in plasma by this type of inhibitors relatively high concentrations were determined.

AbstrakPenelitian ini dilatarbelakangi oleh menguatnya wacana mengenai pentingnya perlindungan data pribadi  dan terbitnya Peraturan Menteri Komunikasi dan Informatika Nomor 20 Tahun 2016 tentang Perlindungan Data Pribadi dalam Sistem Elektronik. Adapun tujuan penelitian adalah untuk mengetahui kinerja implementasi Peraturan Menteri tersebut di lingkungan Pemerintah Kabupaten. Penelitian  dilakukan di Dinas Kependudukan dan Pencatatan Sipil pada Pemerintah Kabupaten Gianyar, Temanggung, dan Sleman dengan menggunakan metode studi kasus, sedangkan pengum­pu­lan data menggunakan teknik studi pustaka, wawancara, dan observasi. Pembahasan dilakukan dengan menggunakan konsep implemen­tasi model Edwards yang melihat implementasi berdasarkan variabel komunikasi, sumber-sumber, kecenderungan-kecenderu­ngan, dan struk­tur birokrasi. Hasil penelitian menunjuk­kan bahwa penyelenggaraan administrasi kependudukan yang di dalamnya termasuk perlindungan data pribadi oleh Dinas Kependudukan dan Pencatatan Sipil merujuk pada Peraturan Menteri Dalam Negeri Nomor 61 Tahun 2015, sedangkan Peraturan Menteri Komunikasi dan Informatika Nomor 20 tahun 2016 sama sekali belum mereka ketahui. AbstractThis research is motivated by the strengthening of discourse regarding the importance of protecting personal data and the issuance of Minister of Communication and Information Regulation No. 20 of 2016 concerning Protection of Personal Data in Electronic Systems. The research objective is to determine the performance of the implementation of the Ministerial Regulation within the District Government. The study was conducted at the Department of Population and Civil Registration at the Government of the Regency of Gianyar, Temanggung, and Sleman by using a case study method, while data collection using literature study techniques, interviews, and observations. The discussion was carried out using the concept of implementation of Edwards model that looked at implementation based on communication variables, sources, trends, and bureaucratic structure. The results showed that the administration of population administration which included the protection of personal data by the Population and Civil Registry Office referred to the Minister of Home Affairs Regulation No. 61 of 2015, while the Minister of Communication and Information Regulation No. 20 of 2016 was completely unknown to them.
