The aim of this study was to develop chemical improvements to the original Weber protocol, in order to increase the intensity and time length of light emission and to eliminate false-positive reactions. The intensity and duration of light were measured on serial blood dilutions using a plate reader chemiluminometer. Blood stains of various concentrations were impregnated in pure cellulose, dried, and luminol solution was added with/without the potential enhancers. An in silico study was also conducted, aiming to demonstrate the enhancing mechanism of hemoglobin denaturation using 8 M urea. The luminol blood detection test revealed important improvements after urea pretreatment or in the presence of monochloro-triazinyl-β-cyclodextrin. This approach also eliminated the false-positive reaction from sodium hypochlorite. These improvements could provide a higher sensitivity under particular circumstances such as old or washed blood stains, leading to a better localization for further DNA typing and higher quality photographic analysis.

The rationale of this paper is based on a deep fascination with the nature of identification, not only from a scientific point of view, but also from an existential and ethical perspective. In the field of Forensic Medicine the identification get extreme significance for a living person, being a proof of his or her existence. Especially in the modern society where everything has to be identified in order to be proved, identification is crucial. This paper is an attempt to make a philosophical approach to some identification methods, which are claimed by their supporters to be based on the theory of "uniqueness". It is a challenging claim which is counteracted in an argumentative discussion. The conclusions of these paper are: uniqueness should not be used in forensic science, as it belongs to the realm of a pure philosophy because the "uniqueness" is impossible to prove.

The phenomenon of defensive medicine existed for decades in the United States but in Romania emerged lately following malpractice litigation and mass media aggression. Defensive medicine develops when doctors prescribe tests or procedures and avoid to treat high-risk patients or to perform certain high-risk procedures in order to reduce the risk of medical liability. This essay discusses the basis and principles of defensive medicine, analyses its causes and effects and debates the major problems affectingRomanian healthcare system, notably cross-border medical assistance. Finally, the authors examine alternatives to prevent defensive medicine practices with emphasis on cardiovascular surgery. Among physicians, some degree of defensive medicine will always exist, as long as malpractice risks shadow the doctors' every footstep.

In this paper, the authors want to introduce the concept of responsibility of an alive person to the values and rights of the deceased person through the ethical professional-personal model introduced, which will help us to make a decision when it comes to issues of morality and ethics in the forensic practice.

The influence of high blood alcohol levels in vehicle drivers involved in car accidents is a growing process, despite the legal punishments which have been already increasing in severity. Therefore, determining the level of blood alcohol concentration at the moment of the car accident is essential in establishing the legal responsibility of the driver. However this exact determination is in most of the cases difficult, due to the fact that between the moment of the car accident and the collecting of the blood in a medical unity a varying time frame passes, depending essentially of the distance from the place of the car accident and the hospital. Even more, from a juridical point of view, at the moment the blood is taken from the driver in the hospital, this is not representing a social danger anymore because he is not driving. Hence, the retrograde extrapolation of blood alcohol concentration is and should be the legal tool of providing the juridical system a valid answer at the question implying the value of the blood alcohol concentration at the moment the antisocial deed (car accident) had been made. The aim of this article is to theoretically present the scientific method of retrograde extrapolation of blood alcohol concentration and also to highlight its strong and weak points.
