One of the key observations about the distribution of life on Earth is that it is non-random in space and time. Description of these spatio-temporal patterns represents the data of biogeography, and explanation of these spatio-temporal patterns has driven the development of the science of biogeography. Perhaps the concept most associated with the description of distributions is endemism, which ...
Thomas Hanna traced his lineage of somatic education back through two primary teachers: F.M. Alexander (The Alexander Technique) and M. Feldenkrais (Functional Integration). Though he acknowledged other teachers as well (Hanna: 1990), these are the two he cited as most central to his lineage. All of the developments in the field entailed two aspects: sensory awareness and motor (movement) contr...
The CyIIIa.CAT fusion gene was injected into Strongylocentrotus purpuratus eggs, together with excess ligated competitor sequences representing subregions of the CyIIIa regulatory domain. In this construct, the chloramphenicol acetyltransferase (CAT) reporter gene is placed under the control of the 2300 nucleotide upstream regulatory domain of the lineage-specific CyIIIa cytoskeletal actin gene...
2223 LETTERS evolutionarily distinct from other AIVs (5). This H5N5 strain is a contemporary reassortant virus related to North American and Eurasian strains. The positive animals we identified originated from a single location on the Antarctic Peninsula, which suggests recent introduction of this AIV H5N5 in the colonies sampled. Antarctica is refuge for most penguin colonies, including the ne...
The CyHIa • CAT fusion gene was injected into Strongylocentrotus purpuratus eggs, together with excess ligated competitor sequences representing subregions of the Cyllla regulatory domain. In this construct, the chloramphenicol acetyltransferase (CAT) reporter gene is placed under the control of the 2300 nucleotide upstream regulatory domain of the lineage-specific CyCIa cytoskeletal actin gene...
Mixed lineage kinase 3 (MLK3) is a mitogen-activated protein kinase kinase kinase (MAPKKK) that activates c-jun N-terminal kinase (JNK) and can induce cell death in neurons. By contrast, the activation of phosphatidylinositol 3-kinase and AKT/protein kinase B (PKB) acts to suppress neuronal apoptosis. Here, we report a functional interaction between MLK3 and AKT1/PKBalpha. Endogenous MLK3 and A...
Blastic natural killer (NK) cell lymphoma is a rare neoplasm characterized by blastoid tumor cells expressing CD4 and CD56, with predominant skin involvement. Although this tumor has been regarded as a neoplasm related to NK cell, recent studies suggested that it is derived from plasmacytoid dendritic cells, but not from NK cell. Herein we report 4 cases of CD4+CD56+ lineage marker-blastic NK c...
