Many laboratories utilize different types of opto-mechanical positioning devices in their experiments.Such devices include lateral stages, which provide 1-dimenstional translational movement, 3-dimensional translation stages, and laboratory jacks, which provide a convenient way of changing the vertical position of a sample.Recent advances in and af
Tetrazolium salts are widely used in biology as indicators of metabolic activity - hence termed vital dyes - but their reduction site is still debated despite decades of intensive research.The prototype, 2,3,5- triphenyl tetrazolium chloride, which was first synthesized a century ago, often generates a single formazan granule at the old pole of Esc
ABSTRACT Cancer related to hereditary syndromes corresponds to approximately 5-10% of all tumors.Among those from Cabinets the genitourinary system, many tumors had been identified to be related to genetic syndromes in the last years with the advent of new molecular genetic tests.New entities were described or better characterized, especially in ki
Diffraction methods are commonly used for the determination of the elastic lattice deformation and distortion from the displacement and broadening of the diffraction peak.These methods enable researchers to measure stresses and elastic properties of polycrystalline materials.The main advantages of diffraction methods are their non-destructive chara
