The foundation of tissue engineering for either therapeutic or diagnostic applications is the ability to exploit living cells. Tissue engineering utilizes living cells as engineering materials implanted, seeded or bio-plotted into an artificial structure capable of supporting three-dimensional tissue formation. These structures, typically called scaffolds, are critical, both ex vivo and in vivo, to influence their own microenvironments. Scaffolds can serve the following purposes: allow cell attachment and migration, deliver and retain cells and biochemical factors, enable diffusion of vital cell nutrients or expressed products, exert certain mechanical and biological influences to modify the behaviour of the cell phase...

INTRODUCTION: Urological surgeries have contributed to the increasing prevalence of minimally invasive robotic procedures. Although factors influencing the adoption of robotic-assisted radical prostatectomy have previously been identified, the explanation for the rapid rise in robotic partial nephrectomies remains unknown. Using a retrospective population-based sample, we attempt to determine hospital and surgeon-specific factors influencing a surgeon's decision to utilize robotic assistance for partial nephrectomies...

The investigation of molecules and materials at interfaces is critical for the accumulation of new scientific insights and technological advances in the chemical and physical sciences. Immobilization on solid surfaces permits the investigation of different properties of functional molecules or materials with high sensitivity and high spatial resolution. Liquid surfaces also present important media for physicochemical innovation and insight based on their great flexibility and dynamicity, rapid diffusion of molecular components for mixing and rearrangements, as well as drastic spatial variation in the prevailing dielectric environment...

In this issue of Healthcare Papers, Anne Snowdon clearly articulates the elements necessary for a health system innovation agenda. Although these steps are not easy - witness the slow progress of the adoption and diffusion of innovation across Canadian healthcare - they are relatively simple and provide a nice counterpoint to our usual concerns about how to effect change within the complex environment of healthcare. The commentators in this issue re-enforce the importance of particular elements or the feasibility of taking some of the first hard steps...

We apply three plausible algorithms in agent-based computer simulations to recent experiments on social learning in wild birds. Although some of the phenomena are simulated by all three learning algorithms, several manifestations of social conformity bias are simulated by only the approximate majority (AM) algorithm, which has roots in chemistry, molecular biology and theoretical computer science. The simulations generate testable predictions and provide several explanatory insights into the diffusion of innovation through a population...

Soils contaminated with mercury (Hg) have proved expensive and logistically difficult to remediate. Research continues into finding suitable environmentally-friendly and efficient ways of achieving this end. Bioremediation is an option, which employs the strategies microorganisms have evolved to deal with Hg. One microbial strategy involves uptake and intracellular volatilisation of mercuric ions, which passively diffuse from the cell and back into the atmosphere. In this work, Pseudomonas veronii cells grown to stationary phase were immobilised in a xanthan gum-based biopolymer via encapsulation...

In May 2006, Colombia's Constitutional Court liberalized abortion, introducing three circumstances under which the procedure would not be considered a crime: (1) rape or incest; (2) a risk to the woman's health or life; and (3) fetal malformations incompatible with life. Immediately following the court's ruling, known as Sentence C-355, members of La Mesa por la Vida y Salud de las Mujeres (hereinafter La Mesa) began to mobilize to ensure the decision's implementation, bearing in mind the limited impact that the legal framework endorsed by the court has had in other countries in the region...

BACKGROUND AND AIMS: Recent years have seen a rise in new and innovative policies to reduce alcohol consumption and related harm in England, which can be implemented by local, as opposed to national, policy-makers. The aim of this paper is to explore the processes that underpin the adoption of these alcohol policies within local authorities. In particular, it aims to assess whether the concept of policy transfer (i.e. a process through which knowledge about policies in one place is used in the development of policies in another time or place) provides a useful model for understanding local alcohol policy-making...

Many chronic wounds exhibit high matrix metalloproteinase (MMP) activity that impedes the normal wound healing process. Intradermal delivery (IDD) of sub-antimicrobial concentrations of doxycycline, as an MMP inhibitor, could target early stages of chronic wound development and inhibit further wound progression. To deliver doxycycline intradermally, the skin barrier must be disrupted. Microneedle rollers offer a minimally invasive technique to penetrate the skin by creating multiple microchannels that act as temporary conduits for drugs to diffuse through...

Acute respiratory distress syndrome (ARDS) is a multifactorial syndrome with high morbidity and mortality rates, characterized by deficiency in gas exchange and lung mechanics that lead to hypoxemia, dyspnea, and respiratory failure. Histologically, ARDS is characterized by an acute, exudative phase, combining diffuse alveolar damage and noncardiogenic edema, followed by a later fibroproliferative phase. Despite an enhanced understanding of ARDS pathogenesis, the capacity to predict the development of ARDS and to risk-stratify patients with the disease remains limited...

Adenylate kinases (AKs) are ubiquitous monomeric phosphotransferases, which play a pivotal role in the energetic metabolism. At the present, nine isoforms are known. AKs catalyze the following reversible reaction: ATP + AMP ↔ 2 ADP, even though isoform 3 uses GTP instead ATP. For many years, the activity of AKs has been detected only after native polyacrylamide gel separations, i.e. in the absence of sodium dodecyl sulfate or methanol. In this work, we report the possibility to detect the activity of the isoforms able to use ATP as substrate, directly onto gel or nitrocellulose sheets, after denaturing SDS-PAGE and electroblotting...

The organizers founded Progress in Community Health Partnerships with a commitment to improving our understanding of community-based participatory research (CBPR) and its use in community-academic/institutional health partnerships. Following Rogers's Diffusion of Innovations, they reasoned that expanded adoption would occur through academic and community partner recognition of CBPR's relative advantage over previous approaches; its compatibility with the values, past experience and needs of potential adopters; its ease of understanding and use; its capacity for experimentation and refinement; and its production of observable results...

An innovative benign process for recovery lactic acid from its fermentation broth is proposed using a novel hyper-cross-linked meso-micropore resin and water as eluent. This work focuses on modeling the competitive adsorption behaviors of glucose, lactic acid and acetic acid ternary mixture and explosion of the adsorption mechanism. The characterization results showed the resin had a large BET surface area and specific pore structure with hydrophobic properties. By analysis of the physicochemical properties of the solutes and the resin, the mechanism of the separation is proposed as hydrophobic effect and size-exclusion...

The type and variety of learning strategies used by individuals to acquire behaviours in the wild are poorly understood, despite the presence of behavioural traditions in diverse taxa. Social learning strategies such as conformity can be broadly adaptive, but may also retard the spread of adaptive innovations. Strategies like pay-off-biased learning, by contrast, are effective at diffusing new behaviour but may perform poorly when adaptive behaviour is common. We present a field experiment in a wild primate, Cebus capucinus, that introduced a novel food item and documented the innovation and diffusion of successful extraction techniques...

Efficient catalytic cascades that involve several sequential reactions are found frequently in nature. The efficiency of multi-step biochemical pathways is enhanced by substrate channelling, wherein the product of one reaction is directed toward and acts as substrate to the next sequential reaction. Such mechanisms can partially overcome diffusion, which is often fast compared to reaction rates, and promotes loss of intermediates. Biochemical substrate channelling is achieved by the architecture and scaffolding of enzymes, and mimicking these natural structures could lead to innovative catalyst designs...
