The actin cell cortex in eukaryotic cells is a key player in controlling and maintaining the shape of cells, and in driving major shape changes such as in cytokinesis. It is thereby constantly being remodeled. Cell shape changes require forces acting on membranes that are generated by the interplay of membrane coupled actin filaments and assemblies of myosin motors. Little is known about how th...

This paper benefitted from presentations at the American Law and Economics Association Meetings, the National Bureau of Economics Law & Economics Summer Session (2003), the NYU Law and Finance Workshop and the University of San Diego Law and Political Theory Workshop, and from comments by Barry Adler, Jennifer Arlen, Ian Ayres, Richard Brooks, Allen Ferrell, Michael Klausner, Alvin Klevorick, J...

INTRODUCTION The clinical application of upper limb (UL) three-dimensional movement analysis (3DMA) in children with unilateral cerebral palsy (uCP) remains challenging, despite its benefits compared to conventional clinical scales. Moreover, knowledge on UL movement pathology and how this relates to clinical parameters remains scarce. Therefore, we investigated UL kinematics across different m...

The Multicenter AIDS Cohort Study (MACS), an ongoing prospective study of the natural history of human immunodeficiency virus (HIV), has stored biologic specimens, including peripheral blood mononuclear cells (PBMC), from 5,622 participants for up to 12 years. The purpose of the present analysis was to evaluate the quality of the PBMC in the MACS repository in order to test the validity and fea...

BACKGROUND Couples with unexplained infertility (UI) tend to have low fertilization rates with current IVF procedures. Here, we attempted to identify spermatozoa with apoptotic markers in couples with UI and unsuccessful intrauterine insemination (IUI) and we investigated the efficiency and benefit of magnetic-activated cell sorting (MACS) for sperm preparation in such patients. METHODS Sixty...

Diverse animal taxa metamorphose between larval and juvenile phases in response to bacteria. Although bacteria-induced metamorphosis is widespread among metazoans, little is known about the molecular changes that occur in the animal upon stimulation by bacteria. Larvae of the tubeworm Hydroides elegans metamorphose in response to surface-bound Pseudoalteromonas luteoviolacea bacteria, producing...

BACKGROUND Several lung diseases are increasingly recognized as comorbidities with HIV; however, few data exist related to the spectrum of respiratory symptoms, diagnostic testing, and diagnoses in the current HIV era. The objective of the study is to determine the impact of HIV on prevalence and incidence of respiratory disease in the current era of effective antiretroviral treatment. METHOD...

Wireless sensor networks (WSN) collect and report measurements, such as temperature, to a central node. Because sensors are usually low-powered devices, data is transmitted hop-by-hop, through neighboring nodes, before it reaches the destination. Each nodes’ messages are authenticated with a MAC (Message Authentication Code), keyed with a key known to the generating sensor and the control node....

This paper looks at the management accounting and control system (MACS) changes in the Housing Authority of Fiji (hereafter HA) from the wider social and political dimensions. The HA has been set up to provide affordable shelter and mortgage finance for low and middle-income earners in Fiji. The subject organisation has been able to meet the demands of customers. Presently, the HA has been able...
