Angiogenesis, the formation of new blood vessels from preexisting vasculature, is essential for many physiological processes, and aberrant angiogenesis contributes to some of the most prevalent human diseases, including cancer....
Head and neck squamous cell carcinomas (HNSCC) often metastasize to locoregional lymph nodes, and lymph node involvement represents one of the most important prognostic factors of poor clinical outcome. HNSCCs are remarkably...
Thrombospondin-1 (TSP-1) is an endogenous inhibitor of angiogenesis whose expression suppresses tumor growth in vivo. Like many angiogenesis-related genes, TSP-1 expression is tightly controlled by various mechanisms, but there...
OBJECTIVES: The diagnosis of cervical lymph node metastasis in head and neck squamous cell carcinoma (HNSCC) patients constitutes an essential requirement for clinical staging and treatment selection. However, clinical...
ABSTRACT.—Because of the “montane island” effect and relative rates of climate change, alpine species may be particularly affected by changing climate. White-tailed Ptarmigan (Lagopus leucura) are adapted to life in the alpine...
Semaphorins are a family of membrane-bound and secreted type of proteins which were initially identified as chemorepulsive axon guidance molecules. Plexins and neuropilins are two major receptor families of semaphorins, and...
The White-tailed Ptarmigan (<em>Lagopus leucurus</em>) is one of the few socially monogamous species within the highly polygynous grouse subfamily (Tetraoninae). I found White-tailed Ptarmigan in Glacier National Park, Montana,...
Castor canadensis Kuhl (North American beavers) are central place foragers who<br />collect woody plants and building materials from their surroundings and return to a main body of water containing a lodge or food cache. It has...
Multiple human malignancies rely on C-X-C motif chemokine receptor type 4 (CXCR4) and its ligand, SDF-1/CXCL12 (stroma cell-derived factor 1/C-X-C motif chemokine 12), to metastasize. CXCR4 inhibitors promote the mobilization...
The scientific process is nonlinear, unpredictable, and ongoing. Assessing the nature of science is difficult with methods that rely on Likert-scale or multiple-choice questions. This study evaluated conceptions about the...
