Controlled nanostructrures formation by ultra fast laser pulses for color marking.

Precise nanostructuration of surface and the subsequent upgrades in material properties is a strong outcome of ultra fast laser irradiations. Material characteristics can be designed on mesoscopic scales, carrying new optical properties. We demonstrate in this work, the possibility of achieving material modifications using ultra short pulses, via polarization dependent structures generation, that can generate specific color patterns.

[Examination over a foreign body left inside during an operation of a lumbar spine].

Procedure of an examination over a gauze swab removed during a repeated operation of a patient who had undergone earlier a neurosurgical operation of a lumbar spine has been described. The extracted gauze swab became an exhibit in a case at court for financial compensation. The court commissioned to explain "if it could be placed in another way than leaving it during the former surgical operation".

[VNTR-PCR in diagnosis of inherited Rb gene mutation].

Molecular genetic analysis of DNA by PCR-VNTR was performed in a family with hereditary retinoblastoma presenting some difficulties in pedigree analysis. PCR-VNTR allowed to perform a more accurate counselling in this family. Analysis of the way of transmission, carrier status exclusion (in two persons) and confirmation (in one) was possible only by VNTR-PCR.

[RFLP-PCR technique for exclusion of carrier status of the mutated Rb gene].

Molecular-genetic analysis of DNA by PCR-RFLP technique in a family with a case of unilateral retinoblastoma was performed. The carrier status of mutated Rb gene in a sister of proband was excluded on the basis of molecular analysis despite unsynonymous pedigree data.
