This work presents a probabilistic lighting model for rendering of thin fur of mammals under environmental influence, particularly water. We have extended the technique known as Fakefur by adding a method for capturing the key characteristics of fur influenced by water. The system described in this work has a lower computational cost than typical resolvable fur methods, due not only to its prob...
This communication presents observations of predatory and non-predatory encounters between white sharks and Cape fur seals in a shallow (3–6 m) channel between Geyser Rock and Dyer Island, South Africa. Within the channel Cape fur seals raft extensively for thermoregulatory purposes, to play, or due to terrestrial competition for space. The channel’s physical environment effectively limits a wh...
The production of high levels of ammonia allows the human gastric pathogen Helicobacter pylori to survive the acidic conditions in the human stomach. H. pylori produces ammonia through urease-mediated degradation of urea, but it is also able to convert a range of amide substrates into ammonia via its AmiE amidase and AmiF formamidase enzymes. Here data are provided that demonstrate that the iro...
Furanodiene (FUR) is a natural terpenoid isolated from Curcumae Rhizoma, a well-known Chinese medicinal herb that presents antiproliferation activities in several cancer cell lines. In this study, we demonstrated that FUR concentration dependently inhibits the cell proliferation of A549, NIH-H1299, and 95-D lung cancer cells. β-elemene, another terpenoid isolated from Curcumae Rhizoma, exhibite...
Ferric uptake regulator (Fur) is a global regulator that controls bacterial iron homeostasis. In this study, a fur deletion mutant of the deep-sea bacterium Shewanella piezotolerans WP3 was constructed. Physiological studies revealed that the growth rate of this mutant under aerobic conditions was only slightly lower than that of wild type (WT), but severe growth defects were observed under ana...
In wild-type Rhizobium leguminosarum, the sitABCD operon specifies a Mn(2+) transporter whose expression is severely reduced in cells grown in the presence of this metal. Mutations in the R. leguminosarum gene, mur (manganese uptake regulator), whose product resembles the Fur transcriptional regulator, cause high-level expression of sitABCD in the presence of Mn(2+). In gel-shift mobility assay...
We demonstrate the feasibility of rendering fur directly into existing images, without the need to either painstakingly paint over all pixels, or to supply 3D geometry and lighting. We add fur to objects depicted in images by first estimating depth and lighting information and then re-rendering the resulting 2.5D geometry with fur. A brush-based interface is provided, allowing the user to contr...
The aim of this study was to investigate the relationship between continuous lead exposure and the concentration of this metal in fur. The two main questions we wanted to answer were: 1) Are the fur lead concentrations different according to exposure level? 2) Is the kinetics of lead concentration linear in different compartments?For 12 weeks, 6 rats were force-fed with water containing lead ac...
Iron is a nutrient of critical importance for the strict anaerobe Clostridium acetobutylicum, as it is involved in numerous basic cellular functions and metabolic pathways. A gene encoding a putative ferric uptake regulator (Fur) has been identified in the genome of C. acetobutylicum. In this work, we inactivated the fur gene by using insertional mutagenesis. The resultant mutant showed a slow-...
