AbstractPigs provide a sensitive and quantitative animal model of complement (C) activation-related pseudoallergy (CARPA) caused by liposomes and a wide range of nanoparticulate drugs or drug nanocarriers (nanomedicines). The tetrad of symptoms (hemodynamic, hematological, laboratory and skin changes) that arise within minutes after i.v. injection of reactogenic nanomedicines (RNMs) are highly reproducible among different pigs but the presence, direction and relative severity of symptoms are very different with different RNMs and their administration schedule. Bolus administration of RNMs usually trigger pulmonary hypertension with or without various degrees of systemic hyper- or hypotension, tachy-or bradycardia, arrhythmia, blood cell and inflammatory mediator changes and skin rash. These reactions can be rapid or protracted, and fully tachyphylactic, semi-tachyphylactic or non-tachyphylactic. Slow infusion usually diminishes the reactions and/or entail delayed, protracted and less severe hemodynamic and other changes. The goal of this review is to present some technical details of the porcine CARPA model, point out its constant and variable parameters, show examples of different reactions, highlight the unique features and capabilities of the model and evaluate its utility in preclinical safety assessment. The information obtained in this model enables the understanding of the complex pathomechanism of CARPA involving simultaneous anaphylatoxin and inflammatory mediator actions at multiple sites in different organs.

AbstractThe construction project being studied is a government investment related to the relocation of a biomedical institute delivering research-based knowledge and contingency support in the fields of animal health, fish health and food safety. The project covers a total of 63,000 square meters distributed over 10 buildings with a very high degree of complexity. The design alone has required 1 million hours, which relates to a client cost of about 100 million Euro. The purpose of this paper is to study the applied methodology for managing the detailed design to identify lessons learned from the project. The theory underlying the study is inspired by lean design management and design theory linked to design as phenomena, including reciprocal interdependencies, iteration, decomposition, design as a “wicked problem”, learning, gradual maturation, etc. The article is based on an abductive research design and has been implemented as a case study where both qualitative and quantitative methods have been used.

Building Project

In parallel with China's growing construction market, there has been an influx of foreign architectural and engineering design firms into the Chinese construction market. Those firms generally form partnerships with local Chinese firms or institutions to overcome various complications in the country. Adding to the complexity, relatively recent technologies such as Building Information Modelling (BIM) also started to play a role in those collaborative project design management efforts in China. This paper presents an in-depth case study of a complex building design project collaboratively executed using BIM by a foreign design firm from the USA and local Chinese firm in China. The project was analysed from different design management and stakeholder perspectives. Some of the findings confirm the pervious accounts from the literature. New insights and the key lessons learned for BIM based design management in this context are also presented.

Product Realization

A flexible information model for systematic development and deployment of product families during all phases of the product realization process is crucial for product-oriented organizations. In this paper we propose a unified information model to capture, share, and organize product design contents, concepts, and contexts across different phases of the product realization process using a web ontology language (OWL) representation. Representing product families by preconceived common ontologies shows promise in promoting component sharing while facilitating search and exploration of design information over various phases and spanning multiple products in a family. Three distinct types of design information, namely, (1) customer needs, (2) product functions, and (3) product components captured during different phases of the product realization process, are considered in this paper to demonstrate the proposed information model. Product vector and function component mapping matrices along with the common ontologies are utilized for designer-initiated information exploration and aggregation. As a demonstration, six products from a family of power tools are represented in OWL DL (Description Logic) format, capturing distinct information needed during the various phases of product realization.

Purpose This paper serves as a case study, detailing an academic library’s three-year process of redesigning, implementing, and using a library electronic classroom. The purpose of this paper is to share the challenges and successes of a library’s attempt to create a high-tech space that both accommodates active learning and is entirely flexible and free of wires. The paper provides technical details for implementing features such as wireless screen sharing and offers practical advice for librarians who are creating new teaching and learning spaces at their institutions. Design/methodology/approach This is a descriptive case study, which details the lessons learned in implementing an active learning space that incorporates technology such as wireless display to multiple screens. Findings There are still major challenges in having a truly wire-free classroom including authentication policies, wireless display technology, instructor’s station mobility, and student laptop control. Successes include flexible furniture, battery-power management solutions, and using multiple wireless devices in a single room. Practical implications Practical implications of this paper include recommendations for planning this type of upgrade in a library electronic classroom. Originality/value The unique feature of this case was the effort to combine the mobile features of a flexible learning space with some of the robust technology of a hardwired active learning classroom. This paper features technical details beyond what can be found in the library literature. For example, very little has been written about the issues involved in wirelessly displaying a computer screen to multiple devices in a classroom.

AbstractReconstruction of long tracheal defects still proves to be a challenge. Free fasciocutaneous flaps with cartilaginous struts or an allotransplant trachea have been reported but not been widely performed. This article reports with the experience of using a tracheal allotransplant in such a defect.A 43-year-old lady presented with adenoid cystic carcinoma involving the entire trachea from subglottic area up to the carina, leading to a life-threatening airway occlusion. After preliminary stenting, allotransplant trachea obtained from a brain-dead individual was revascularized in the forearm of the patient after mechanical decellularization to reduce the immune load and fulfil the need for immunosuppression in the background of active cancer. Subsequently, the trachea and larynx were resected. The vascularized neotrachea was transferred successfully into the neck. The patient did well initially but succumbed to a fatal hemorrhage due to innominate vein aneurysmal rupture on the 22nd day after the transplant.The technical details of resection, fabrication of the neotrachea, its transfer, and the lessons learnt in this tracheal allotransplant are described.
