During the next two weeks, floral-color change could be investigated in Aster divaricatus or A. prenanthoides, both of which grow on my property. You could investigate one or more of the above hypotheses relative to the situation in Aster. For example, you could investigate whether the presence of color-changed flowers enhances the plant as a visual target for pollinators as well as determine w...

The treatment of psychiatric disorders presents threemajor challenges to the research and clinical community: defining a genotype associated with a disorder, characterizing themolecular pathologyof eachdisorder anddevelopingnew therapies.ThisReviewaddresseshowcellularand animal systems can help to meet these challenges, with an emphasis on the role of the zebrafish. Genetic changes account for ...

Floral-color Changes Floral-color changes are common among the angiosperms. At least three non-exclusive hypotheses have been proposed to explain these changes: 1. Once flowers are adequately pollinated, further pollinator visits impair reproduction by deposition of self-pollen, dislodging of pollen, or damage to floral parts. 2. Color changes mark flowers that have been depleted of their rewar...

Growth hormone insensitivity syndrome (GHIS) has been reported in a family homozygous for a point mutation in the GH receptor (GHR) that activates an intronic pseudoexon. The resultant GHR (GHR1-656) includes a 36 amino-acids insertion after residue 207, in the region known to be important for homodimerization of GHR. We have examined the functional consequences of such an insertion in mammalia...

OBJECTIVES This study was undertaken to determine the proportion of persons primarily with developmental disabilities who encounter difficulties accessing dental care in Ontario, to identify perceived barriers to accessing dental care and to determine if persons with disabilities and their caregivers believe that oral health is important. METHODS Community organizations providing services mai...

Ivacaftor is currently used for the treatment of cystic fibrosis as both monotherapy (Kalydeco; Vertex Pharmaceuticals, Boston, MA) and combination therapy with lumacaftor (Orkambi; Vertex Pharmaceuticals). Each therapy targets specific patient populations: Kalydeco treats patients carrying one of nine gating mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) protein, w...
