A three-dimensional (3D) mineralizing culture system using hollow fiber bioreactors has been developed to study the early stages of endochondral ossification by proton nuclear magnetic resonance (NMR) microscopy. Chondrocytes harvested from the…
The thick (> 4000 m) coarsening-upward terrestrial Neogene sequence of the Sulaiman Range (Middle Indus Basin, central Pakistan) is the western extension of the Siwalik outcrop belt of the Sub-Himalayas. The near-shore to terrestrial sedimentation in…
Stimulation of active fluid transport with beta-adrenergic receptor (betaAR) agonists can accelerate the resolution of alveolar edema. However, chronic betaAR-agonist administration may cause betaAR desensitization and downregulation that may impair…
This study investigated whether interest inventories that purport to measure the same constructs actually yield scores that correspond. The study examined the empirical relation of scores for similarly and same-named scales on five widely used…
Before discussing how to innovate the study of career development using insights from life-span psychology and life course sociology, researchers might benefit from reconsidering whether they are studying careers or studying vocational behavior.…
Models of career maturity first formulated at midcentury, have been criticized for not incorporating innovations in personality and developmental psychology. This isolation from general models of and debates about personal maturity has kept career…
A partial skeleton was recovered from middle Miocene Muruyur sediments near Kipsaramon in the Tugen Hills, Baringo District, Kenya. The specimen, representing much of the upper skeleton, comes from locality BPRP#122 dated between 15(.)58 Ma and…
Several researchers have investigated, or commented on, the relative placement of the hominin mandibular fossa with regard to brain expansion and masticatory function. Two confounding factors are identified in this previous work. First, a number of…
Temporal bone morphology, as part of the basicranium, is commonly used in systematic evaluation of early hominid fossils. When an isolated right temporal bone, KNM-BC 1 (the Chemeron temporal) was discovered in the Baringo Basin, Kenya, Tobias…
Fungal infection is a rare but devastating complication of total joint arthroplasty. Many patients require removal of the components and resection arthroplasty for cure; however, revision arthroplasty with medicated polymethylmethacrylate bone cement…
We assessed the bacterial contamination of the pagers of healthcare personnel and the efficacy of disinfection with 70% isopropyl alcohol. Microorganisms were isolated from all pagers; 21% yielded Staphylococcus aureus, of which 14% were methicillin…
Early cetaceans evolved from terrestrial quadrupeds to obligate swimmers, a change that is traditionally studied by functional analysis of the postcranial skeleton(1). Here we assess the evolution of cetacean locomotor behaviour from an independent…
We describe 6 patients who had bacteremic community-acquired pneumonia and unsuspected Legionella pneumophila coinfection. We reviewed case records of patients who were diagnosed as having a recent Legionella infection on the basis of either the…
The origin and early evolution of Cetacea (whales, dolphins, and porpoises) is one of the best examples of macroevolution as documented by fossils. Early whales are divided into six families that differ greatly in their habitats, which varied from…
We determined if kainic acid, a neuroexcitotoxin, could be used to denervate the cell bodies of cardiopulmonary vagal sensory neurons. Kainic acid (5 mug) was injected into the nodose ganglion of five dogs. Ten to fourteen days following this…
The sterol 12alpha-hydroxylase (CYP8B1) is a key enzyme of the bile acid biosynthetic pathway. It regulates the composition of bile acids in bile, i.e. ratio between cholic acid (CA) and chenodeoxycholic acid (CDCA). In similarity with cholesterol…
Context Participation in proficiency testing is required under the Clinical Laboratory Improvement Amendments of 1988. Although the primary purpose of this testing is evaluation of current laboratory performance, a major secondary benefit of such…
