Cervicovaginal self-sampling is a reliable method for determination of prevalence of human papillomavirus genotypes in women aged 20 to 30 years.

Self-sampling by cervicovaginal lavage could be an attractive method to detect high-risk human papillomavirus (hr-HPV) infections to identify women with a risk of cervical precancer. The objective of our study was to use self-sampling for the first time in a cross-sectional approach to determine HPV prevalence and genotype distribution. We evaluated participants' acceptance and laboratory results from self-obtained samples versus endocervical brush samples obtained by gynecologists.

Synthesized femtosecond laser pulse source for two-wavelength contouring with simultaneously recorded digital holograms.

A dual-wavelength femtosecond laser pulse source and its application for digital holographic single-shot contouring are presented. The synthesized laser source combines sub-picosecond time scales with a wide reconstruction range. A center wavelength distance of the two separated pulses of only 15 nm with a high contrast was demonstrated by spectral shaping of the 50 nm broad seed spectrum centered at 800 nm.

An oxygen imaging system for medical applications: preliminary results.

The examination of functional processes in tissue is gaining importance in medical research. As a result the imaging and monitoring of biochemical parameters in vivo is the goal of many imaging methods. One key parameter in photodynamic therapy (PDT) is the molecular oxygen concentration.
