Photocatalytic degradation of 2,4-dichlorophenol using nanomaterials silver halide catalysts.

In this study, the photocatalytic activity of nanomaterials Ag/AgX (X = Cl, Br, I) is reported. Highly efficient silver halide (Ag/AgX where X = Cl, Br, I) photocatalysts were synthesized through a hydrothermal method. The samples were characterized using a range of techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) to check their structural, morphology, textural and optical properties.

Demographic and clinical determinants of neck pain in idiopathic cervical dystonia.

Cervical dystonia is associated with neck pain in a significant proportion of cases, but the mechanisms underlying pain are largely unknown. In this exploratory study, we compared demographic and clinical variables in cervical dystonia patients with and without neck pain from the Italian Dystonia Registry. Univariable and multivariable logistic regression analysis indicated a higher frequency of sensory trick and a lower educational level among patients with pain.

Multiple infarcts in a patient with cerebral phaeohyphomycosis: CT and MRI.

Phaeohyphomycosis is an uncommon disorder caused by a variety of saprophytic fungi having distinctive morphologic features. Central nervous system infection typically occurs in the absence of predisposing factors and usually manifest symptoms and signs of abscess formation. We describe an otherwise healthy young man whose presentation with cerebral phaeohyphomycosis was subacute meningitis and stroke.
