Microfluidic sensor for white blood cell counting and flow metering
Cell counting finds many applications in diagnostics of many diseases. One of the most common tests recommended by the physicians is Complete Blood Cell Count (CBC). For example, there is a decrease in the platelet count in case of Dengue fever. Red blood cells decrease in the case of anemia. CD4 T …

Mikrobielle Ökologie N-Acyl-L-Homoserinlacton-produzierender Bakterien in der Rhizosphäre von Tomatenpflanzen
… in gram-negative bacteria, which regulate, in a cell density dependent way, important interactive functions. This phenomenon is known as quorum-sensing. This work characterised the microbial ecology of the autoinducer (AHL) producing bacteria Serratia liquefaciens MG1 and Pseudomonas putida IsoF …

Effects of survivin and survivin inhibition in canine models of lymphoma and osteosarcoma
… protein that inhibits apoptosis and drives cell proliferation, is commonly elevated in human and canine cancer. Survivin expression is a negative prognostic factor in both dogs and humans with LSA and OS, and canine LSA and OS cell lines express high levels of survivin. Due to the strong …

Role of ETV5 Mutations in B Cell Acute Lymphoblastic Leukemia
B cell acute lymphoblastic leukemia (B-ALL) develops through the acquisition of driver mutations that impair cell differentiation and promote proliferation. In human B-ALL, mutations in E26 transformation-specific (ETS) transcription factors are commonly reported. Our laboratory studies a mouse …

Cell Phenotype Analyzer: Automated Techniques for Cell Phenotyping using Contactless Dielectrophoresis
… cannot be cured. However, if the precise cancer cell type is diagnosed at an earlier, less aggressive stage then the chance of curing the disease increases with accurate drug delivery. This work is a humble contribution to the advancement of cancer research. This work delves into biological cell …
