serpentine/atrophy

Two cases of serpentine supravenous hyperpigmentation developing in the area of fotemustine infusions are reported. Histological features showed an increased melanin synthesis and the presence of melanophages without focal degeneration of basal cells or dermal inflammatory infiltrate. Perls' strain

Giant serpentine aneurysms (GSAs) are infrequent. We present a 37-year-old patient with a giant serpentine aneurysm of the left middle cerebral artery that was treated with a superficial temporal artery to middle cerebral artery bypass and ligature of the left internal carotid artery. After 2 years,

Anthropogenic and nonanthropogenic (erosion) processes contribute to the continuing presence of asbestos and nonasbestos elongated mineral particles (EMP) of amphibole and serpentine in air and water of urban, rural, and remote environments. The anthropogenic processes include disturbance and

A widely distributed mineral, serpentine, obtained from Wadi Ghadir (Eastern Desert in Egypt) was studied as a potential naturally and abundantly available source for the synthesis of an efficient adsorbent for aquatic remediation applications. A novel nanocomposite was synthesized after the

Heterotrimeric guanine nucleotide-binding proteins (G proteins) act as signal-transducing molecules that connect serpentine-transmembrane receptors to a variety of intracellular effectors. We characterized a Caenorhabditis elegans G(s) gene, gsa-1, which encodes a G(s) alpha-subunit (G alpha(s))

BACKGROUND Giant serpentine aneurysms (GSAs) are a subgroup of giant intracranial aneurysms, distinct from saccular and fusiform varieties, that are defined as partially thrombosed giant aneurysms with tortuous internal vascular channel. Clinicopathologic characteristics of middle cerebral artery

A 10-liter serpentine-type microbial fuel cell (MFC) stack was constructed by extending 40 tubular air-cathode MFC units in a 3-D alignment pattern. When operated in series and fed with brewery wastewater, the stack produced an open circuit voltage of 23.0V and a maximum power density of 4.1W/m(3)

Increasing evidence suggests that deficient immune modulation and microbial infections underline neurodegeneration, but the mechanisms remain obscure. Here, we show that the G-protein-coupled receptor (GPCR) SRBC-48, which belongs to the class BC serpentine receptors, has a protective role in

We propose a flexible and wearable thermoelectric nanogenerator (FTEG) made from Bi2Te3, which allows high voltage and output power density. The proposed FTEG works as a thermopile with the end-to-end connection of 126 thermoelectric legs, and which is fabricated through magnetron sputtering Cu

Mycobacterial cell wall contains various lipids (glycolipids and phospholipids) to contribute to its hydrophobic property or acid-fastness and these surface molecules contact with host cells in the early step of infection. Among them, cord factor (trehalose 6,6'-dimycolate, TDM or CF) is the most

Arteriovenous malformations (AVM's) of the spine commonly cause progressive myelopathy. Occasionally, myelography reveals serpentine filling defects characteristic of a spinal AVM, but an AVM or arteriovenous (AV) fistula cannot be demonstrated arteriographically, despite selective catheterization

Mammalian spinal motoneuron dendrites respond with cyclic degeneration and regeneration after ventral root crush. In the following experiments, the cross-sectional dendritic profile of rat lamina IX, medial, motoneurons under the T2 vertebra were analyzed after mincing the dorsal horn (normals, 14,

This report presents a patient with an intradural spinal arteriovenous fistula complicated by infarction of the cord. The diagnosis of an arteriovenous malformation was made on the magnetic resonance imaging (MRI) study with the demonstration of intraspinal serpentine areas of low signal intensity

In this report we describe the clinical history and symptoms in a 36-year-old male with Hajdu-Cheney syndrome, an autosomal dominant condition with dissolution of the terminal phalanges (acro-osteolysis), characteristic craniofacial dysmorphism, and musculoskeletal alterations. He was admitted at

Carcinoid tumors of the lung have a wide histologic spectrum. The histologic differential diagnosis of papillary tumors in the lung generally does not include carcinoid. A carcinoid tumor that formed a discrete coin lesion on chest radiograph is presented in this report. On gross examination the
