摘要：业主希望这是一栋设计简单、充满阳光、可以让人觉得无限放松的房子,对这个灵活性十足的设计方案非常满意。该住宅的用地是长方形的,坐落在城市的郊区。设计师将房子设计成一个长方体,高低错落的结构给人以视觉的美感。房屋对着道路的那一面是封闭的,完全保留了住宅的私密性。房子的起居室和卧室向着花园开放,将室外的景色引入室内,增强了人与自然的互动,给人以动人的视觉享受。

摘要：Avian influenza, subtype H5N1, causes occasional but serious infections in humans and efforts to produce vaccines against this strain continue. Current influenza vaccines are prophylactic and utilize the two major antigens, hemagglutinin and neuraminidase. Nucleocapsid protein (NP) is an attractive alternative antigen because it is highly conserved across all influenza strains, has been shown to increase the rate of viral clearance, and potential therapeutic vaccines would elicit cytotoxic T lymphocyte responses in an infected person. The NP antigen from H5N1 was characterized using a variety of physico-chemical methods to gain insights into both the biological and physical properties of the antigen which are important from a regulatory viewpoint when considering therapeutic vaccines. Results obtained to date show that NP is relatively unstable and indicate that the conformation of the H5N1 NP antigen is highly dependent upon purification procedure, buffer conditions, pH and the presence or absence of RNA. These factors will need to be clearly defined and taken into consideration when manufacturing and regulating NP vaccine preparations.
