Manufacturing Dendritic Cells for Immunotherapy: Monocyte Enrichment
Dendritic cells play a key role in activation of the immune system as potent antigen-presenting cells. This pivotal position, along with the ability to generate dendritic cells from monocytes and ready uptake of antigen, makes them an intriguing vehicle for immunotherapy for a variety of indications. Since the first reported trial using dendritic cells in 1995, they have been used in trials all over the world for a plethora of indications. Monocyte-derived dendritic cells are generated from whole blood or apheresis products by culturing enriched monocytes in the presence of interleukin (IL)-4 and granulocyte-macrophage colony-stimulating factor (GM-CSF). A variety of methods can be used for enrichment of monocytes for generation of clinical-grade dendritic cells and are summarized herein
Active diffusers : some prototypes and 2D measurements
Diffusing devices are used to improve room acoustics in a wide variety of applications. The dispersion generated by current diffuser technologies is often limited to mid-to-high frequencies because low-frequency diffusers are usually too large to be easily accommodated. To extend the bandwidth of diffusers to a lower frequency a new approach is proposed, that is to use active control technology. In particular, active impedance techniques have been exploited to create non-absorbing diffusers, and hybrid structures that partly absorb while dispersing any reflected sound. This paper presents results mostly from a feedforward structure. It is found that achieving active dispersion without absorption other a worthwhile bandwidth can be more difficult than achieving active absorption due to the more complex target impedance that the controller needs to learn. Measurements on polar responses provide evidence that the active diffusers can achieve wider bandwidth dispersion. Boundary element modelling has enabled the design of these structures to be examined in more application-realistic set-ups
Spin-Flavor Separation and Non-Fermi Liquid Behavior in the Multichannel Kondo Problem: A Large N Approach
We consider a generalization of the multichannel
single-impurity Kondo model which we solve analytically in the limit
, , with fixed. Non-Fermi
liquid behavior of the single electron Green function and of the local spin and
flavor susceptibilities occurs in both regimes, and , with
leading critical exponents {\em identical} to those found in the conformal
field theory solution for {\em all} and (with ). We explain
this remarkable agreement and connect it to ``spin-flavor separation", the
essential feature of the non-Fermi-liquid fixed point of the multichannel Kondo
problem.Comment: 14 pages, 1 Figure (Poscript file attached), Revte

APEL, APL or CPD?
Acquired prior experiential learning (APEL), acquired prior learning (APL) and/or continuous professional development (CPD) in the form of short courses or degree courses can ensure current and future employment.CPD is a requirement of regulatory and professional bodies and supported by healthcare organizations.It has been recognized that patients and healthcare institutions benefit when healthcare practitioners are competent. Through CPD health professionals can keep their skills and knowledge up to date and work safely, legally and effectively. </jats:p

Never events in gastrointestinal nursing
Gastrointestinal diseases and disorders frequently require interventions that can lead to serious consequences for patients when an organization has not put in place the correct systems and processes to prevent incidents from happening, procedures have not been followed (generally due to poor observation), or when an individual disregards protocol (generally due to lack of judgment). It has been identified that over 400,000 patients suffer potentially preventable harmful events each year (Emslie, 2002). In this article, Carol Cox describes the types of risks that can lead to never events and factors that increase the potential for error
