rhBMP(骨形成タンパク質)v-FRIOS Algipore(石灰藻由来の多孔質ハイドロキシアパタイト)複合体がラットを用いた直接覆髄実験において効果的に良質な修復象牙質形成を誘導するか検討した。BMP-HA群は、HA群、水酸化カルシウム群に比べて早期から旺盛な修復象牙質形成を認め、細管構造を有する緻密な構造であった。BMP-HA群では早期から炎症が軽度で、全実験期間を通して他の実験群に比べて歯髄の炎症の程度は軽度であった。水酸化カルシウム製剤によって誘導された修復象牙質は全体的に多孔質で、トンネル状の欠陥が存在し、全ての観察期間を通して歯髄に炎症反応を認めた。歯髄保存療法剤としてのrhBMPv-FRIOS Algipore複合体の有効性が示唆された

Exploration, development and production activities for natural gas are technology-driven. These difficult and complex activities will not bring economic prosperity of the country unless the gas is properly utilh,ed. Gas distribution plays a pivotal role in appropriate usc of natural gas. It is the vital interface between the industry and the end users. Revenue is brought in by the distribution companies. So for a healthy business, it is imperative that the distribution system runs at the highest efficiency. Performance of all the distribution companies in Bangladesh is ruined by a phenomenon called 'System loss', It acoounts for 8% of the total gas. Apart from very little system requirement of gas (less than 2%) the rest of it is stolen. Technical and administrative flaws in system design, along with improper and old equipment use worsens the problem. Before embarking new network expaw;iolL,identification of the existing problems are very important. Titas Gas Transmission an...

Although transboundary river flow accounts for more than 40% of global surface flow across 145 nations (many of them water-stressed and conflict-prone), most of this flow is difficult to monitor in developing nations at operational timescales. For Bangladesh, this situation is particularly acute because it comprises only 7% of the entire Ganges-Brahmaputra-Meghna basin and is located at the downstream end
