then combined these four variables (Cronbach's α = 0.897) to generate one composite variable, indicating participant likelihood of using ayahuasca over other hallucinogens in the future. Thus, this variable served as an index of the magnitude of

Most veterinary and milk hygiene laboratories identify streptococci and enterococci based on serological and biochemical tests. The analysis of 16S rDNA was suggested to be used for more exact identification; however, its use has not been considered so far in monitoring studies. The objective of the present study was to compare a conventional phenotypic method with restriction fragment length polymorphism analysis of 16S rDNA (16S rDNA RFLP) for identification of streptococci isolated from composite milk samples collected in connection with intramammary infection (IMI) in six Argentinean dairy farms. Composite milk samples (n = 1223) from cows belonging to six herds were collected for bacteriological analysis. Twelve reference strains and fifty streptococci or streptococcuslike isolates were identified to species level by the API 20 Strep system, conventional biochemical tests and 16S rDNA RFLP in a blind assay. The remaining streptococci or streptococcus-like isolates (n = 40) were identified to the species level both by 16S rDNA RFLP and conventional biochemical tests. As indicated by Kappa values, agreement between the 16S rDNA RFLP and the conventional scheme for identification of Streptococcus agalactiae, S. dysgalactiae, S. uberis, S. equinus and Enterococcus faecalis was 0.91, 0.73, 0.92, 0.81 and 0.85, respectively. Together with the less frequently isolated streptococcal species, the conventional scheme correctly identified 77 out of 90 isolates (85.5%). Thus, the use of 16S rDNA RFLP is considered valuable for monitoring studies due to its affordable cost for standard laboratories.

The dental pulp was capped indirectly or directly, or partial vital pulpectomy was performed on the 12 functionally most important teeth of 24 beagle dogs. For pulp capping, calcium hydroxide was used, followed by zinc phosphate as a lining, and the preparation was restored with amalgam or composite material. Histological sections were prepared and examined for degree and type of pulp inflammation (hyperaemia, pulpitis, necrosis or gangrene). Degenerative changes of dental pulp (vacuolation, calcification, amyloid or hyaline changes) were also determined. For indirect pulp capping the width of predentine in crown and root dental pulp was measured, and for direct pulp capping and partial pulpectomy (vital pulpotomy) the width and quality of the dentinal bridge were graded. The radical method of partial vital pulpectomy of the coronal part of the dental pulp in dogs produced better quality and continuity of the dentinal bridge than the less radical method of direct pulp capping. This was particularly obvious in small single root teeth such as incisors.

A percutan coronariaintervenció a stabil coronariabetegség tüneti kezelésének régóta alkalmazott módszere. A szerző a közelmúlt szakirodalmának, különös tekintettel a FAME 2 vizsgálat eredményeit bemutató publikáció áttekintésével arra a kérdésre keres választ, hogy miért nem sikerült a percutan coronariaintervenció halálozást vagy a myocardialis infarctus előfordulását csökkentő hatását igazolni stabil coronariabetegségben, szemben a sebészi revascularisatióval. A FAME 2 vizsgálatban sikerült igazolni, hogy a csak gyógyszeres kezeléshez képest a fractional flow reserve vezérelte, második generációs gyógyszert kibocsátó stentimplantációval végzett percutan coronariaintervenció a halálozás, a myocardialis infarctus és a sürgős revascularisatióval járó nem tervezett kórházi felvétel előfordulását csökkenti, illetve a periproceduralis szak után a halálozás és myocardialis infarctus is szignifikánsan ritkább. A szerző kiemeli, hogy a fractional flow reserve meghatározásával és modern stent alkalmazásával a percutan coronariaintervenció nem csupán tüneti hatással bír a stabil coronariabetegség kezelésében.

Objectives

The international distribution and commodification of ayahuasca has created virtual communicative realms in the Internet in which members intensively exchange personal narratives, advertisements, and beliefs about ayahuasca and its reputed native background. Common consumption standards and beliefs about ayahuasca have developed among western ayahuasca drinkers who are often only loosely connected to the local practice of ayahuasca-shamanism in regions of the upper Amazonas that are not yet influenced by ayahuasca tourism. Those new standards of the ayahuasca tourism are reflected in the Internet. Motivation and expectation of interested ayahuasca tourists gets shaped in Internet forums. Previous studies about the motivation of western ayahuasca drinkers have mainly used heuristic qualitative methods. This study characterizes ayahuasca Internet activists and examines statistically their motivational structure to drink ayahuasca.

Methods

Using online data collection and quantitative analysis methods, 40 participants were studied who were active in closed Facebook groups about ayahuasca in the year 2015.

Results

The average active members of ayahuasca Facebook groups in this sample seem to be 28–50 years old (±1 SD), higher education degree holders, preexperienced with other psychedelic drugs and other psychospiritual methods, preexperienced with ayahuasca and motivated to drink again, and tend toward the intake within organized events such as shamanic healing ceremonies and retreat seminars. The results suggest that the motivation of Internet activists for ayahuasca consists in majority of four main elements: self-exploration, spiritual purposes, physical health issues, and sensation seeking. Self-exploration and spiritual purposes appear to be the main reasons for drinking ayahuasca. Physical health issues and sensation seeking are minor reasons among this subgroup of western ayahuasca drinkers but may play a larger role in some participants.

Conclusions

The motivation of members of social ayahuasca networks in the Internet seems not to be monodimensional but a composite of different aspects of which a subconglomerate of psychospiritual reasons and individual self-development seems to be the most dominant. The findings support motivational differences to local ayahuasca shaman clients in the upper Amazonas region that have been previously described in the ethnologic literature.
