Forensic electrochemistry: indirect electrochemical sensing of the components of the new psychoactive substance Synthacaine

Synthacaine is a New Psychoactive Substance which is, due to its inherent psychoactive properties, reported to imitate the effects of cocaine and is therefore consequently branded as legal cocaine. The only analytical approach reported to date for the sensing of Synthacaine is mass spectrometry. In this paper, we explore and evaluate a range of potential analytical techniques for its quantification and potential use in the field screening Synthacaine using Raman spectroscopy, presumptive (colour) testing, High Performance Liquid Chromatography (HPLC) and electrochemistry. HPLC analysis of street samples reveals that Synthacaine comprises a mixture of methiopropamine (MPA) and 2-aminoindane (2-AI). Raman spectroscopy and presumptive (colour) tests, the Marquis, Mandelin, Simon's and Robadope test, are evaluated towards a potential in-the-field screening approach but are found to not be able to discriminate between the two when they are both present in the same sample, as is the case in the real street samples. We report for the first time a novel indirect electrochemical protocol for the sensing of MPA and 2-AI which is independently validated in street samples with HPLC. This novel electrochemical approach based upon one-shot disposable cost effective screen-printed graphite macroelectrodes holds potential for in-the-field screening for Synthacaine.

A contratransferência e a importância das capacidades do analista na prática psicanalítica contemporânea

Although the use of countertransference is a controversial topic and the debate on the participation of the analyst’s mind may go back to the old conception of aptness for the analytical task based on personality or psychological makeup, the fact is that the psychoanalyst’s education involves the elaboration of his unconscious conflicts, turning conscious the pathways of his desire and his symptoms through a process of personal analysis and a long theoretical and technical training in the field of psychoanalysis. This study is a literature review based on studies about the maternal function, which aims at showing the path of recovery of countertransference in psychoanalytic theory and technique and the implication of the analyst’s abilities in the analytical process. This development is tributary of the appreciation of maternal function as a model for interpersonal and therapeutic relationship in Psychoanalysis, due to the paradigm of object relations in the British psychoanalytic tradition, being Donald W. Winnicott and Wilfred R. Bion two of its main authors.

Investigação da poluição por metais tóxicos no córrego do Cintra

Cintra stream is the major receiver of treated effluent from sanitary, hospital and research laboratory sewage from the UNESP campus in Botucatu, Rubião Júnior District, São Paulo state; and it has shown evidence of diffuse contamination by metals along it. Analyses of the most toxic metals (Pb, Cu, Fe, Ni and Zn) were carried out by using an atomic absorption spectrometer AA-6.800 - Perkin Elmer, analyst 700. ANOVA followed by the Tukey test were used for data analyses at 5% significance level. The main objective of this study was to compare current data on metal levels with data from other studies, in the same area, and of the same nature, conducted before and after implementation of chemical residue management by the university in 2008. Also, it aimed at identifying and quantifying possible diffuse and punctual contamination. Sites S1 and S2 showed punctual contamination, while diffuse sources were observed between S4 and S5. The quality of water in the Cintra Stream improved after establishment of the program of laboratory chemical residue management in the Campus of UNESP.
