Abstract:
1041 Background: Identification of gene expression-based breast cancer subtypes is considered a critical means of prognostication. Genetic mutations along with epigenetic alterations contribute to gene-expression changes occurring in breast cancer. However, the reproducibility of differential DNA methylation discoveries for cancer and the relationship between DNA methylation and aberrant gene expression have not been systematically analysed. The present study was undertaken to dissect the breast cancer methylome and to deliver specific epigenotypes associated with particular breast cancer subt

Field-grown seedlings of ‘Alamo’ switchgrass (Panicum virgatum L.) from Vonore, TN exhibited light brown-to-dark brown leaf spots and general chlorosis in June 2009. Symptomatic leaf tissue was surface sterilized (95% ethanol for 1 min, 20% commercial bleach for 3 min, and 95% ethanol for 1 min), air dried on sterile filter paper, and plated on 2% water agar amended with 10 mg/liter rifampicin (Sigma-Aldrich, St. Louis, MO) and 5 μl/liter miticide (2.4 EC Danitol, Valent Chemical, Walnut Creek, CA). Plates were incubated at 26°C for 4 days in darkness. An asexual, dematiaceous mitosporic fungu

Abstract:
There are few reports on diseases of switchgrass. In November 2009, light brown to white bleached spots (1 to 2 × 3 to 4 μm) were observed on ‘Alamo’ switchgrass (Panicum virgatum L.) grown in a growth chamber in Knoxville, TN, from surface-disinfested seed produced in Colorado. Symptomatic leaf tissue was surface sterilized, air dried, and plated on 2% water agar (WA) amended with 6.9 mg fenpropathrin/liter (Danitol 2.4 EC, Valent Chemical, Walnut Creek, CA) and 10 mg/liter rifampicin (Sigma-Aldrich, St. Louis, MO).

Abstract:
Abstract We introduce a non-increasing tree growth process $((T_n,{\sigma}_n),\, n\ge 1)$ , where T n is a rooted labelled tree on n vertices and σ n is a permutation of the vertex labels. The construction of (T n , σ n ) from (Tn−1, σn−1) involves rewiring a random (possibly empty) subset of edges in Tn−1 towards the newly added vertex; as a consequence Tn−1 ⊄ T n with positive probability. The key feature of the process is that the shape of T n has the same law as that of a random recursive tree, while the degree distribution of any given vertex is not monotone in the process. We present two

Widespread changes in the expression of genes occur whenS. mutansis presented with competence signal peptidesin vitro, including the increased production of the alternative sigma factor, ComX, which activates late competence genes. Still, the way that gene products that are regulated by competence peptides influence DNA uptake and cellular physiology are not well understood.

Abstract:
This master’s thesis deals with analysis and following optimisation of a Sigma TN sports car suspension. Knowledge of vehicle dynamics and strength of materials was used during the optimisation. Kinematic and force analysis was carried out in software ADAMS Car. A FEM analysis was processed in Ansys Workbench environment. Three design concepts were worked out, in which Topology optimisation also found use.
