Low-Molecular-Weight Heparins as Immunomodulators in Dermatology Practice
No full textLow-molecular-weight heparins (LMWHs) have some effects on cell proliferation and inflammation beyond mere anticoagulation. They have been tried on treatment of a few dermatological disorders such as lichen planus, skin wound healing, recurrent aphtous stomatitis, chronic urticaria, and contact hypersensitivity. LMWHs are generally well-tolerated drugs, rarely can lead to severe reactions. In this article, we will review the novel indications of LMWHs in dermatology practice and common skin reactions associated with their use

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Narrow band ultraviolet B for the treatment of generalized lichen planus
No full textObjective: Although various treatment options have been used in the treatment of lichen planus (LP), it is still challenging to choose the most effective one. Scarce data are available in the literature examining efficacy of NB-UV in the treatment of LP. Thus, we aimed to evaluate efficacy of NB-UVB for LP.Methods: Twenty-four patients with generalized LP who received NB-UVB treatments in between January 2011 and December 2014 were included in the study. Response types were classified into three groups which complete response refers to 90% reduction in the number of the lesions; partial response 51-89%; and no response 50%.Results: Sixteen patients responded to the NB-UVB treatment [5 partial (20.8%) and 11 complete (45.8%) remissions], whereas 8 patients (33.3%) did not respond to the treatment. A number of sessions and accordingly cumulative dose of UVB were significantly higher in responded group than in non-responders. When we compared these two groups according to duration of the disease, there was no significant difference.Conclusions: Two-thirds of patients with generalized LP favorably responded to NB-UVB treatment without any remarkable adverse events. This significant response rate coupled with safety should prompt further clarification of the place of NB-UVB in generalized LP

Length 15– 19 µm, breadth 3–4 µm. Axial area very narrow, straight, expanded transversely to form a rectangular central area bordered on each side near the margin by a shortened stria.

Septa and pseudosepta small at both poles.</p> <p> Internally, valves of <i>G. capitata</i> appear to express only two of the isolated stigmoids (Figs 393, 394). Other features of the valve interior include proximal raphe ends recurved in the same direction, helictoglossae aligned with the axis of the raphe, and pseudosepta at the apices (Figs 392–394). Externally, the raphe has prominently dilated proximal ends and distal ends that are barely deflected onto the mantle (Fig. 396). Striae are doubly-punctate and terminate near the axial area with one or two areolae.
