BACKGROUND Atrophic dermatofibroma is an uncommon variant of dermatofibroma. It lacks the classic clinical features of a dermatofibroma and is often misdiagnosed. OBJECTIVE To describe the clinical and histologic features of atrophic dermatofibroma. METHODS Case report and review of the literature. RESULTS A 45-year-old white woman was found to have a 7 mm x 5 mm atrophic, depressed lesio...

This study investigates the effects of uncertainty in rockphysics models on estimates of reservoir parameters from joint inversion of seismic AVA and CSEM data. The reservoir parameters are related to electrical resistivity using Archie’s law, and to seismic velocity and density using the Xu-White model. To account for errors in the rock-physics models, we use two methods to handle uncertainty:...

Recent progress in neuroscience has been facilitated by tools for neuronal activation and inactivation that are orthogonal to endogenous signaling systems. We describe here a chemical-genetic approach for inducible silencing of Caenorhabditis elegans neurons in intact animals, using the histamine-gated chloride channel HisCl1 from Drosophila and exogenous histamine. Administering histamine to f...

To increase fertilization chances compared with rivals, males are favoured to transfer accessory gland proteins to females during mating. These substances, by influencing female physiology, cause alteration of her sperm usage and remating rate. Simultaneously hermaphroditic land snails with love-darts are a case in point. During courtship, a love-dart is pierced through the partner's body wall,...

Anetoderma is a rare cutaneous disease characterized by a loss of normal elastic tissue that is presented clinically as localized areas of wrinkled or flaccid skin. This form may be associated with several immunological abnormalities, most notably lupus erythematosus and antiphospholipid antibodies with or without clinical manifestations of the antiphospholipid syndrome. A retrospective study w...

Many studies have reported the phytotoxicity of allelopathic compounds under controlled conditions. However, more field studies are required to provide realistic evidences for the significance of allelopathic interference in natural communities. We conducted a 2-years field experiment in a semiarid plant community (NE Spain). Specifically, we planted juvenile individuals and sowed seeds of Sals...

We herein report the case of a 73-year-old woman who developed skin and nail disorders 2 months before her digestive symptoms started, which lead to the diagnosis of gastric adenocarcinoma. The lesions were diagnosed as Bazex syndrome, usually seen in squamous cell carcinoma. Under systemic chemotherapy, the cutaneous signs improved for some months before worsening when the disease progressed.

PURPOSE To profile macular thickness changes in glaucoma by using three-dimensional spectral-domain optical coherence tomography (3D-SD-OCT). METHODS The study included 30 eyes with suspected glaucoma and preperimetric glaucoma (SGPPG) and 35 healthy eyes. The macular thickness, including those of the total retina, nerve fiber layer (NFL), and combined inner retinal layers (IRLs)-NFL+ganglion...

The concern with word classes, parts ofspeech, or, as they are referred to in this paper, syntactic categories, dates back to antiquityfor better and for worse. For better, since in lingui stics, as in any other disc ipline, one sees further when standing on the shoulders of giants . But for worse, ifit is the case that the giants themselves are standing in the wrong place. Or, in the case at h...

In DNA of the dinoflagellate Crypthecodinium cohnii, 38% of the thymine is replaced by the modified base 5-hydroxymethyluracil, and approximately 3% of the cytosine is replaced by 5-methylcytosine. Both of the modified bases are non-randomly distributed in the DNA. Determinations of 3' nearest neighbors show that HOMeU is preferentially located in the dinucleotides HOMeUpA and HOMeUpC. Pyrimidi...
