Establishment of a national DNA database in the Republic of Serbia: Legal aspects and implications for the future.

Forensic DNA databases have been established in the vast majority of European countries and represent an essential personal identification instrument in the criminal justice system. The implementation of suitable legislation and accompanying legal practice is an imperative to ensure sensible use of the DNA repository, without interfering with the rights, freedoms and privacy of individuals and their families. Thus, the complex matter of DNA databank effectiveness and intrusiveness is a delicate balancing act, which has resulted in diverse database governing regimes among different countries.

Unbiased entropy estimates in stress: a parameter study.

This study proposes a method for obtaining a stable working point that enables the unbiased estimates of the approximate entropy and the sample entropy. Pattern length, normalized threshold, time delay and tines series length are levels of freedom that are considered. Pulse interval signals used for the experiment are recorded from laboratory animals with different likelihood of developing cardiovascular disease--normal and borderline hypertensive rats--exposed to the acute and to the chronic stress.

Environmental stress: approximate entropy approach revisited.

Radiotelemetred male Wistar outbrad rats and Borderline Hypertensive rats (BHR) were exposed to acute and chronic environmental stress. Approximate entropy (ApEn) approach is applied in order to investigate the pulse interval (PI) response to two different types of environmental stress: shaker and restrain stress. The performance of ApEn method was evaluated from the parameter selection point of view.
