A new “Logicle” display method avoids deceptive effects of logarithmic scaling for low signals and compensated data
Authors: Parks David R. , Roederer Mario , Moore Wayne A. 
Published: April 2006

AbstractBackground:In immunofluorescence measurements and most other flow cytometry applications, fluorescence signals of interest can range down to essentially zero. After fluorescence compensation, some cell populations will have low means and include events with negative data values. Logarithmic presentation has been very useful in providing informative displays of wide‐ranging flow cytometry data, but it fails to adequately display cell populations with low means and high variances and, in particular, offers no way to include negative data values. This has led to a great deal of difficulty in interpreting and understanding flow cytometry data, has often resulted in incorrect delineation of cell populations, and has led many people to question the correctness of compensation computations that were, in fact, correct.Results:We identified a set of criteria for creating data visualization methods that accommodate the scaling difficulties presented by flow cytometry data. On the basis of these, we developed a new data visualization method that provides important advantages over linear or logarithmic scaling for display of flow cytometry data, a scaling we refer to as “Logicle” scaling. Logicle functions represent a particular generalization of the hyperbolic sine function with one more adjustable parameter than linear or logarithmic functions. Finally, we developed methods for objectively and automatically selecting an appropriate value for this parameter.Conclusions:The Logicle display method provides more complete, appropriate, and readily interpretable representations of data that includes populations with low‐to‐zero means, including distributions resulting from fluorescence compensation procedures, than can be produced using either logarithmic or linear displays. The method includes a specific algorithm for evaluating actual data distributions and deriving parameters of the Logicle scaling function appropriate for optimal display of that data. It is critical to note that Logicle visualization does not change the data values or the descriptive statistics computed from them. © 2006 International Society for Analytical Cytology
Multiplexed and microparticle‐based analyses: Quantitative tools for the large‐scale analysis of biological systems
Authors: Nolan John P. , Mandy Francis 
Published: April 2006

AbstractWhile the term flow cytometry refers to the measurement of cells, the approach of making sensitive multiparameter optical measurements in a flowing sample stream is a very general analytical approach. The past few years have seen an explosion in the application of flow cytometry technology for molecular analysis and measurements using microparticles as solid supports. While microsphere‐based molecular analyses using flow cytometry date back three decades, the need for highly parallel quantitative molecular measurements that has arisen from various genomic and proteomic advances has driven the development in particle encoding technology to enable highly multiplexed assays. Multiplexed particle‐based immunoassays are now common place, and new assays to study genes, protein function, and molecular assembly. Numerous efforts are underway to extend the multiplexing capabilities of microparticle‐based assays through new approaches to particle encoding and analyte reporting. The impact of these developments will be seen in the basic research and clinical laboratories, as well as in drug development. © 2006 International Society for Analytical Cytology
Tigroid background in fine‐needle aspiration cytology of clear cell sarcoma
Authors: Rau Aarathi R. , Kini Hema , Verghese Rebecca 
Published: April 2006

AbstractClear‐Cell Sarcoma (CCS) is a rare malignant soft tissue tumor of young adults that often metastasizes to the lymph nodes. The fine needle aspirate cytology (FNAC) findings of CCS have been described previously and it is included in the cytological category of polygonal soft tissue tumors. We describe the cytology of a case of CCS, with emphasis on the so called “tigroid background.” Though this tigroid background is a nonspecific feature and has been described in various other tumors, to the best of our knowledge, it has not been described in CCS. This feature may be useful in the recognition of CCS. Diagn. Cytopathol. 2006;34:355–357. © 2006 Wiley‐Liss, Inc.
Fine‐needle aspiration cytology of thymic basaloid carcinoma: Case studies and review of the literature
Authors: Posligua Lorena , Ylagan Lourdes 
Published: April 2006

AbstractWe report the features in fine‐needle aspiration biopsy (FNAB) of thymic basaloid carcinomas. This is a rare neoplasm, of which there are only three documented in our hospital files. To the best of our knowledge, this is the first fine‐needle aspiration (FNA) report on basaloid carcinoma of the thymus. This is a tumor in which the FNA diagnosis is difficult and the differential diagnosis is broad. We describe the cytologic features encountered in the three cases, and immunohistochemical and ultrastructural findings so as to raise awareness of this entity in the differential diagnosis of thymic neoplasms on FNABs.The cases studied included three male patients, aged 73, 65, and 50, who presented with anterior mediastinal masses, with no primary tumor elsewhere. FNAB was performed on two cases, followed by thymectomy. One case, additionally, had metastasis to a cervical lymph node, and the other two were associated with thymic cysts. The diagnoses on all three cases were thymic basaloid carcinoma. Diagn. Cytopathol. 2006;34:358–366. © 2006 Wiley‐Liss, Inc.
A pilot project on the potential contribution of palm‐mat geotextiles to soil conservation
Authors: Davies Kathleen , Fullen Michael A. , Booth Colin A. 
Published: April 2006

AbstractGeotextiles constructed from Borassus aethiopum (black rhun palm) leaves are currently being investigated for their effectiveness in decreasing water erosion. The study aims to develop sustainable methods of soil conservation where the material meets selected criteria (readily available, simple and cost‐effective to manufacture, provides immediate erosion control and possibly increases soil fertility and organic matter content). Grid mats were manufactured in a cottage workshop in The Gambia, West Africa. They are currently under investigation at the Hilton Experimental Site in Shropshire, UK. Eight runoff plots (10 × 1 m on a 15° slope) are being used, with duplicate treatments: (i) bare soil; (ii) grassed; (iii) bare soil with 1 m palm‐mat buffer zones at the lower end of the plots; and (iv) completely covered with palm‐mats. Results from one year of field study (2002–03) indicate sediment yield is 36·8 per cent from replicated covered plots and 35·9 per cent from the replicated buffer zone plots, compared to the control bare plots. Sediment yield equated to 0·45 t ha−1 from bare soil, 0·09 t ha−1 from grassed plots and 0·17 t ha−1 from both the covered and buffer zone plots. The results suggest palm‐mat application as protective buffer strips is highly effective in temperate climates. Future work is intended to follow this pilot study and develop well‐researched guidelines for practical field applications in other global regions, namely Africa, Southeast Asia and South America.

Chemical composition of the essential oil of five Iranian Nepeta species (N. crispa, N. mahanensis, N. ispahanica, N. eremophila and N. rivularis)
Authors: Sefidkon F. , Jamzad Z. , Mirza M. 
Published: April 2006

AbstractEssential oils from aerial parts of Nepeta crispa Willd., Nepeta mahanensis Jamzad & Simmonds, Nepeta ispahanica Boiss., Nepeta eremophila Hausskn. & Bornm. and Nepeta rivularis Bornm. were obtained by hydro‐distillation. The oils were analyzed by capillary gas chromatography, using flame ionization and mass spectrometric detection. Twenty‐eight components were identified in the oil of Nepeta crispa with 1,8‐cineole (62.8%), 4aα‐7α‐7aα‐nepetalactone (10.3%) and 4aβ‐7α‐7aβ‐nepetalactone (9.2%) as main constituents. Eighteen compounds were identified in the oil of Nepeta mahanensis with nepetalactone (37.6%), 1,8‐cineole (27.2%) and germacrene D (6.5%) as the main components. Twenty‐seven compounds were characterized in the oil of Nepeta ispahanica with 1,8‐cineole (71.7%) as the main constituent. Twenty‐six compounds were characterized in the oil of Nepeta eremophila with 4aβ‐7α‐7aβ‐nepetalactone (73.3%) and 1,8‐cineole (13.1%) as the main constituents. Twenty‐two components were identified in the oil of Nepeta rivularis with 1,8‐cineole (38.5%), sabinene (14.8%), β‐pinene (10.7%) and γ‐terpinene (5.1%) as the main constituents. The results showed that, although the nepetalactone isomers are the main components of the essential oils of N. mahanensis and N. eremophila, the oil of N. crispa consists of about 20% nepetalactone and the oils of other species have different compositions. 1,8‐Cineole was present in all oils at percentages of 13.1% (the lowest amount in N. eremophila) to 71.7% (the highest amount in N. ispahanica).
