In studying lines in the plane, when we needed to describe how a line was tilting, we used the notions of slope and angle of inclination. In space, we want a way to describe how a plane is tilting. We accomplish this by multiplying two vectors in the plane together to get a third vector perpendicular to the plane. The direction of this third vector tells us the “inclination” of the plane. The p...
Some of the things we measure are determined simply by their magnitudes. To record mass, length, or time, for example, we need only write down a number and name an appropriate unit of measure. We need more information to describe a force, displacement, or velocity. To describe a force, we need to record the direction in which it acts as well as how large it is. To describe a body’s displacement...
In the calculus of functions of a single variable, we used our knowledge of lines to study curves in the plane. We investigated tangents and found that, when highly magnified, differentiable curves were effectively linear. To study the calculus of functions of more than one variable in the next chapter, we start with planes and use our knowledge of planes to study the surfaces that are the grap...
Genotype-specific patterns of atrophy progression are more sensitive than clinical decline in SCA1, SCA3 and SCA6 Kathrin Reetz, Ana S. Costa, Shahram Mirzazade, Anna Lehmann, Agnes Juzek, Maria Rakowicz, Romana Boguslawska, Ludger Schöls, Christoph Linnemann, Caterina Mariotti, Marina Grisoli, Alexandra Dürr, Bart P. van de Warrenburg, Dagmar Timmann, Massimo Pandolfo, Peter Bauer, Heike Jacob...
Auxin elicits diverse cell behaviors through a simple nuclear signaling pathway initiated by degradation of Aux/IAA co-repressors. Our previous work revealed that members of the large Arabidopsis Aux/IAA family exhibit a range of degradation rates in synthetic contexts. However, it remained an unresolved issue whether differences in Aux/IAA turnover rates played a significant role in plant resp...
Implant placement to provide support and retention for nasal prostheses has been described in the literature. The anatomic sites that have been utilized for implant placement are the nasal bones, the premaxillary area through the nasal fossae, and the anterior wall of the frontal sinus. In the patient described, after a presurgical computerized tomography scan to determine adequacy of bone volu...
[This corrects the article DOI: 10.4103/1008-682X.153543.] In published paper by Watanabe, the [Figure 3] on page 905 is incorrect, because of a mistake on computer processing. The correct [Figure 3] follows. The author apologizes to the readers for this careless mistake.
Lipophilic (logP > 1) and amphiphilic drugs (also known as cationic amphiphilic drugs) with ionizable amines (pKa > 6) can accumulate in lysosomes, a process known as lysosomal trapping. This process contributes to presystemic extraction by lysosome-rich organs (such as liver and lung), which, together with the binding of lipophilic amines to phospholipids, contributes to the large volume of di...
It is commonly thought that deep phylogenetic conservation of plant microRNAs (miRNAs) and their targets1,2 indicates conserved regulatory functions. We show that the blind (bl) mutant of Petunia hybrida3 and the fistulata (fis) mutant of Antirrhinum majus4,5, which have similar homeotic phenotypes, are recessive alleles of two homologous miRNA-encoding genes. The BL and FIS genes control the s...
