Introduction: Extracorporeal photopheresis (ECP) has been extensively used for the treatment of immune-mediated diseases for over 20 years and has a consistent and predictable safety profile with long-term use. Documenting the efficacy of ECP as therapeutic treatment has long been a matter of importance for physicians.

Areas Covered: The authors reviewed publications in this field with the goal of providing an overview of this therapeutic approach.

Healthy donors (HDs) who were mobilized using lenograstim (LENO) and who were undergoing peripheral haematopoietic progenitor cell collection with apheresis (HPC-A) were enrolled in a surveillance protocol. In all, 184 HDs have been assessed with a median follow-up of 62 months (range 2-155). HDs received LENO at a median dose of 10 microg/kg (range 5-15).

Background: Toxin complex (Tc) proteins termed TcaABC, TcdAB, and TccABC with insecticidal activity are present in a variety of bacteria including the yersiniae.

Results: The tc gene sequences of thirteen Yersinia strains were compared, revealing a high degree of gene order conservation, but also remarkable differences with respect to pseudogenes, sequence variability and gene duplications. Outside the tc pathogenicity island (tc-PAIYe) of Y.

Twelve Yersinia enterocolitica mutants carrying luxCDABE-transposon insertions in motility and chemotaxis genes were isolated on the basis of strong low-temperature induction. Two transposons were located within an 11.2 kb enteric flagellar cluster 2 (Flag-2) of Y.

To analyze the transcriptional response of Yersinia enterocolitica cells to prolonged growth at low temperature, a collection of luxCDABE transposon mutants was cultivated in parallel at optimal (30 degrees C) and suboptimal (10 degrees C) temperatures and screened for enhanced promoter activities during growth until entering stationary phase. Among 5,700 Y. enterocolitica mutants, 42 transcriptional units were identified with strongly enhanced or reduced promoter activity at 10 degrees C compared to 30 degrees C, and changes in their transcriptional levels over time were measured.

The insecticidal toxin complexes (Tcs) are produced by several Enterobacteriaceae associated with insects, such as Photorhabdus luminescens, Serratia entomophila and Xenorhabdus nematophilus. Genome sequences revealed tc-like genes in Yersinia spp., but insecticidal activity of this genus associated with the toxins has not been described.

Mobilization of CD34+ into peripheral blood is attained by either glycosylated (lenograstim) or non-glycosylated recombinant G-CSF (filgrastim). 101 donors, 57 males, median age 42 years (range 16-63) entered this retrospective study. Group I (55 cases) received filgrastim and group II lenograstim subcutaneously for 5-6 days.

Primary aldosteronism is a disorder characterized by hypertension and hypokalemia due to aldosterone secretion out of renin-angiotensin control. It is generally caused by aldosterone-producing adenoma or adrenocortical hyperplasia but, in some cases, it is due to genetic alterations. Familial type I hyperaldosteronism is the result of anomalous regulation of aldosterone secretion from ACTH (which normally regulates cortisol synthesis).

Bioluminescent mutants of Yersinia enterocolitica were generated by transposon mutagenesis using a promoterless, complete lux operon (luxCDABE) derived from Photorhabdus luminescens, and their production of light in the cheese environment was monitored. Mutant B94, which had the lux cassette inserted into an open reading frame of unknown function was used for direct monitoring of Y. enterocolitica cells on cheeses stored at 10 degrees C by quantifying bioluminescence using a photon-counting, intensified charge-coupled device camera.

Background And Objective: The number of allogeneic transplants of peripheral blood stem cells (PBSC) is rapidly increasing. Collection of PBSC in healthy subjects currently implies the administration of G-CSF or GM-CSF and, of course, the use of apheretic devices. These procedures involve potential risks, in particular the risk of leukemia secondary to growth-factor treatment.
