Inhibition of UVB-induced skin phototoxicity by a grape seed extract as modulator of nitrosative stress, ERK/NF-kB signaling pathway and apoptosis, in SKH-1 mice.

Molecular mechanisms concerning the modulation of nitrosative stress, signal transduction and proliferation/apoptosis by a grape seed extract, Burgund Mare variety (BM), in SKH-1 mice exposed to UVB, were investigated. The animals were irradiated with single and multiple doses of UVB in 10 consecutive days. In each experiment were used five groups of animals: control, vehicle, UVB irradiated, vehicle+UVB, BM+UVB.

The effects of grape seeds polyphenols on SKH-1 mice skin irradiated with multiple doses of UV-B.

The study investigated the protective activity of red grape seeds (Vitis vinifera L, Burgund Mare variety) (BM) extracts in vivo on multiple doses of ultraviolet radiation (UV)-B-induced deleterious effects in SKH-1 mice skin. Eighty 8-weeks-old female SKH-1 mice were divided into 8 groups: control, vehicle, UV-B irradiated, vehicle+UV-B irradiated, BM 2.5mg polyphenols (PF)/cm(2)+UV-B irradiated, BM 4 mg PF/cm(2)+UV-B irradiated, UV-B+BM 2.

Ultrasonography of the eye and orbit.

Ultrasonography (US) is, quite often, the first imaging modality used in eye and orbit assessment. The indications of ophthalmic US cover a wide range of disease where direct clinical assessment is impossible or of little value. Doppler US enhances the ability to assess blood flow in the main arteries and veins.

Interhemispheric lipoma associated with agenesis of corpus callosum in an infant: case report.

Agenesis of the corpus callosum is an anomaly that may occur as isolated or in association with other central nervous system or systemic malformations. We report the case of an infant antenatal diagnosed with ventriculomegaly referred in the postnatal period to our department for imaging evaluation. Ultrasonography showed the absence of the corpus callosum and an interhemispheric lesion highly suggestive for a cerebral lipoma.

Ultrasonographic and sonoelastographic features of pleomorphic adenomas of the salivary glands.

Aims: The typical ultrasound features of pleomorphic adenomas are considered to be the well-defined contour, the regular, sometimes lobulated shape, homogeneous structure and poor vascularization. The goal of our study was to verify the validity of these features and to identify a typical sonoelastographic pattern for pleomorphic adenomas.

Patients And Methods: Between April 2007 and February 2010, 70 salivary gland masses were examined prospectively (58 in the parotid gland, 12 in the submandibular gland).
