BACKGROUND Gadolinium (Gd)-based magnetic resonance contrast agents (GBMCA), including gadodiamide, have been identified as the probable causative agents of the serious disease, nephrogenic systemic fibrosis (NSF). OBJECTIVES To investigate retained Gd-containing deposits in skin biopsies from patients with NSF and to determine their relative concentrations over time from administration of GB...
We report numerical results of effective attractive forces on the packing properties of two-dimensional elongated grains. In deposits of non-cohesive rods in 2D, the topology of the packing is mainly dominated by the formation of ordered structures of aligned rods. Elongated particles tend to align horizontally and the stress is mainly transmitted from top to bottom, revealing an asymmetric dis...
Surface geological and geochemical mapping have been key technical contributors to many gold discoveries over the past 25 years. However, in the last ten years there has been a growing emphasis on using geophysical techniques to compliment them in covered terrains. As the search for gold deposits under covered areas expands, there will be increasing emphasis on integrating the geoscientific dis...
Several highly effective fire-adaptive traits first evolved among modern plants during the mid-Cretaceous, in response to the widespread wildfires promoted by anomalously high atmospheric oxygen (O2) and extreme temperatures. Serotiny, or long-term canopy seed storage, is a fire-adaptive strategy common among plants living in fire-prone areas today, but evidence of this strategy has been lackin...
Joint capsule, meniscus, and cartilage from the patella and medial femoral condyle from 30 non-selected autopsies have been investigated for amyloid deposits with light and electron microscopy. Both right and left knee joints from 28 of the 30 autopsy specimens contained amyloid deposits (93%). The amyloid characteristically showed green dichroism in polarised light after staining with alkaline...
Hepatic venous catheterisation and transvenous liver biopsy were performed in five patients with hepatic amyloidosis. In three patients, hepatic venous pressures were normal and histological examination of the liver biopsy specimen showed discrete and sparse perisinusoidal amyloid deposits. In the other two, however, the gradient between wedged and free hepatic venous pressures was increased (1...
The Eskay Creek gold-silver mine, located in northwest British Columbia, is an unusually high-grade ore deposit. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more detailed surveys to determine if favourable sit...
The Eskay Creek gold-silver mine, located in northwest British Columbia, is the highest-grade precious-metal volcanogenic massive sulphide deposit in the world. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more...
the dehdasht bauxite deposits are located 40 km northeast of dehdasht in kohgilouye and boyer-ahmad province. it is a part of the irano-hymalayan karstic bauxite belt located in the upper part of karstic depressions of santonian-turonian sarvak carbonate formation. the aim of this study is to determine various geneses of pisoliths and prevalent processes in bauxitization. for this purpose, labo...
The post-mortem examination of an unsuspected case of alkaptonuria revealed extensive ochronosis. Histological examination of undecalcified sections of tracheal, costal, femoral and patellar cartilage revealed, in addition to ochronotic pigment, extensive calcium pyrophosphate dihydrate (CPPD) deposition. Similar deposits were present in intervertebral discs and were related to ossification of ...
