<p class="abstract">Granuloma faciale (GF) is a chronic condition characterized by asymptomatic erythematous plaque with prominent telangiectasia presenting usually over the face. Although the condition is benign, its treatment is often unsatisfactory. Therapeutic modalities that have been tried include topical steroids and topical tacrolimus sometimes enhanced with topical dapsone. Others include intralesional corticosteroids, antimalarials, isoniazid and pulsed-dye laser. We report a case of a 58 years old female with a 1 year history of a solitary slowly progressive plaque over the nose. Diagnosis of GF was made based on the histopathological findings. The patient was started on the combination of topical tacrolimus, intralesional corticosteroids injection and oral doxycycline for 3 months. The patient showed gradual improvement in 3 months without any side effects. This case supports previous papers of successful treatment of GF with topical tacrolimus. There was no recurrence at follow-up 18 months later. It also supports the use of combination therapy especially in resistant cases.</p>

Discoid lupus erythematosus is the most common forms of chronic cutaneous lupus erythematosus. It is characterized by clinical manifestations of erythematous macules, papules, or plaques with a coin-like shape and the face is the most common predilection site. Clinical features often resemble granuloma faciale. This case report aimed to distinguish discoid lesions on the face based on the histopathological examination. A 71-year-old male with a few reddish lumps appeared on his face since three months ago. Physical examination showed multiple discrete erythematous plaques with overlying squamous. Hematoxylin and eosin staining on the epidermis demonstrated basket weave type orthokeratosis, basal vacuolar cell degeneration, epidermal atrophy with flat rete ridges, and follicular plugging while in the dermis obtained inflammatory cell infiltrates, especially in periadnexal areas. Histopathological features of DLE are hyperkeratosis, pilosebasea gland atrophy, follicular plugging, basal membrane thickening, and cellular infiltrate in periadnexa or perivascular areas more visible than in other types of CLE. In DLE, no subepidermal gren zone and eosinophil infiltrate were found, like histological features of granuloma faciale. Histopathological examination can be used to establish a diagnosis for discoid lesions on the face, although serology examination remains as the gold standart. Keywords:  Discoid lupus erythematosus; Granuloma faciale; Histopathology

Abstract Granuloma faciale is an uncommon inflammatory skin disorder clinically characterized by single or multiple, reddishbrown nodules or plaques primarily occurring on the face of middle-aged men. Occasionally, extra-facial involvement has been reported, usually on sun-exposed areas. Although the etiology is somewhat unclear, granuloma faciale is considered a localized form of chronic leukocytoclastic vasculitis with a prominent eosinophilic infiltrate and fibrosis in the later stages of the disease. Histological examination of lesions reveals a dense polymorphous inflammatory infiltrate that consists mainly of eosinophils and neutrophils separated from the epidermis by a narrow band zone with normal collagen, deprived of cells. Leukocytoclastic vasculitis is often seen. Clinical diagnosis is suspected in few cases, so definite diagnosis of granuloma faciale requires a biopsy. The disease is notoriously resistant to many therapies and often tends to relapse after treatment is discontinued. We present a female patient with granuloma faciale on the back and on the tip of the nose, misdiagnosed clinically as basall cell carcinoma and granuloma annulare. Her original histological diagnosis, made by a pathologist, was pyogenic granuloma. After revision of histologic findings of the biopsy specimens, granuloma faciale was diagnosed by a dermatopathologist. The treatment with cryotherapy and topical steroids was unsuccessful. Improvement of lesions was observed after use of tacrolimus 0.1% ointment, but lesion recurred after discontinuation of treatment.

AbstractZero-sum thinking and aversion to trade pervade our society, yet fly in the face of everyday experience and the consensus of economists. Boyer & Petersen's (B&P's) evolutionary model invokes coalitional psychology to explain these puzzling intuitions. I raise several empirical challenges to this explanation, proposing two alternative mechanisms – intuitive mercantilism (assigning value to money rather than goods) and errors in perspective-taking.

AbstractThe clear evidence of water erosion on the surface of Mars suggests an early climate much more clement than the present one. Using a model for the origin of inner planet atmospheres by icy planetesimal impact, it is possible to reconstruct the original volatile inventory on Mars, starting from the thin atmosphere we observe today. Evidence for cometary impact can be found in the present abundances and isotope ratios of gases in the atmosphere and in SNC meteorites. If we invoke impact erosion to account for the present excess of129Xe, we predict an early inventory equivalent to at least 7.5 bars of CO2. This reservoir of volatiles is adequate to produce a substantial greenhouse effect, provided there is some small addition of SO2(volcanoes) or reduced gases (cometary impact). Thus it seems likely that conditions on early Mars were suitable for the origin of life – biogenic elements and liquid water were present at favorable conditions of pressure and temperature. Whether life began on Mars remains an open question, receiving hints of a positive answer from recent work on one of the Martian meteorites. The implications for habitable zones around other stars include the need to have rocky planets with sufficient mass to preserve atmospheres in the face of intensive early bombardment.

In zirconium-hydrogen alloys, rapid cooling from an elevated temperature causes precipitation of the face-centred tetragonal (fct) phase, γZrH, in the form of needles, parallel to the close-packed <1120>zr directions (1). With low hydrogen concentrations, the hydride solvus is sufficiently low that zirconium atom diffusion cannot occur. For example, with 6 μg/g hydrogen, the solvus temperature is approximately 370 K (2), at which only the hydrogen diffuses readily. Shears are therefore necessary to produce the crystallographic transformation from hexagonal close-packed (hep) zirconium to fct hydride.The simplest mechanism for the transformation is the passage of Shockley partial dislocations having Burgers vectors (b) of the type 1/3<0110> on every second (0001)Zr plane. If the partial dislocations are in the form of loops with the same b, the crosssection of a hydride precipitate will be as shown in fig.1. A consequence of this type of transformation is that a cumulative shear, S, is produced that leads to a strain field in the surrounding zirconium matrix, as illustrated in fig.2a.

Interphase sliding is an important phenomenon of high temperature plasticity. In order to study the microstructural changes associated with it, as well as its influence on the strain rate dependence on stress and temperature, plane boundaries were obtained by welding together two polycrystals of Cu-Zn alloys having the face centered cubic and body centered cubic structures respectively following the procedure described in (1). These specimens were then deformed in shear along the interface on a creep machine (2) at the same temperature as that of the diffusion treatment so as to avoid any precipitation. The present paper reports observations by conventional and high voltage electron microscopy of the microstructure of both phases, in the vicinity of the phase boundary, after different creep tests corresponding to various deformation conditions.Foils were cut by spark machining out of the bulk samples, 0.2 mm thick. They were then electropolished down to 0.1 mm, after which a hole with thin edges was made in an area including the boundary

There is no doubt that the immense amount of information that is being generated by the initial sequencing and secondary interrogation of various genomes will change the face of glycobiological research. However, a major area of concern is that detailed structural knowledge of the ultimate products of genes that are identified as being involved in glycoconjugate biosynthesis is still limited. This is illustrated clearly by the nematode worm Caenorhabditis elegans, which was the first multicellular organism to have its entire genome sequenced. To date, only limited structural data on the glycosylated molecules of this organism have been reported. Our laboratory is addressing this problem by performing detailed MS structural characterization of the N-linked glycans of C. elegans; high-mannose structures dominate, with only minor amounts of complex-type structures. Novel, highly fucosylated truncated structures are also present which are difucosylated on the proximal N-acetylglucosamine of the chitobiose core as well as containing unusual Fucα1–2Gal1–2Man as peripheral structures. The implications of these results in terms of the identification of ligands for genomically predicted lectins and potential glycosyltransferases are discussed in this chapter. Current knowledge on the glycomes of other model organisms such as Dictyostelium discoideum, Saccharomyces cerevisiae and Drosophila melanogaster is also discussed briefly.
