Metal release from implantable metals and the properties of oxide films formed on alloy surfaces were analyzed, focusing on the highly biocompatible Ti-15Zr-4Nb-4Ta alloy. The thickness and electrical resistance (Rp) of the oxide film on such an alloy were compared with those of other implantable metals. The quantity of metal released during a 1-week immersion test was considerably smaller for ...

E10-5A3 is a dhfr-ts- Leishmania major double knockout auxotrophic shown previously to induce substantial protection against virulent L. major infection in both genetically susceptible and resistant mice. We investigated the capacity of dhfr-ts- to protect against heterologous infection by L. amazonensis. The degree of protection was evaluated by immunization of BALB/c or C57BL/6 mice with E10-...

PURPOSE Tenascin-C is an extracellular matrix glycoprotein found at sites of embryonic cell motility, including the developing visual system. Numerous alternatively spliced variants of tenascin-C have been identified, and these variants have distinctive properties in vitro. The purpose of this study was to use quantitative in situ hybridization to determine the relative abundance of transcripts...

Abstract Sediment cores collected at Lake Kogare-ike, a coastal lake on the Pacific coast of central Japan, record marine inundation history during last 3000 years. The sediments consist mainly organic mud, sand, gravel, inorganic and volcanic ash, events were recognized as 19 event deposits (E1–E19, from top to bottom) interbedded with mud. Visual observation by naked eyes X-ray computed tomog...

Anti-angiogenesis therapy is an emerging strategy for cancer treatment. This therapy has many advantages over existing treatments, such as fewer side effects, fewer resistance problems and a broader tumor type spectrum. Integrin αvβ3 is a heterodimeric transmembrane glycoprotein that has been demonstrated to play a key role in tumor angiogenesis and metastasis. We have used phage antibody displ...

Exponential rise in the use of mobile communication devices has generated health concerns due to radiofrequency (RF) exposure due to its close proximity to the head. Calcium binding proteins like calretinin regulate the levels of calcium (Ca(2+)) which plays an important role in biological systems. Ginseng is known for maintaining equilibrium in the human body and may play a beneficial radiopro...

The aorta-gonad-mesonephros (AGM) region is a potent hematopoietic site in the midgestation mouse conceptus and first contains colony-forming units-spleen day 11 (CFU-S(11)) at embryonic day 10 (E10). Because CFU-S(11) activity is present in the AGM region before the onset of hematopoietic stem cell (HSC) activity, CFU-S(11) activity in the complex developing vascular and urogenital regions of ...

To better understand the relationship between the embryonic hematopoietic and vascular systems, we investigated the establishment of circulation in mouse embryos by examining the redistribution of yolk sac-derived primitive erythroblasts and definitive hematopoietic progenitors. Our studies revealed that small numbers of erythroblasts first enter the embryo proper at 4 to 8 somite pairs (sp) (e...
