BASIC COURSE FOR UROLOGIS: INTRACORPOREAL SUTURING

CCMIJU has organised the II Urological Laparoscopy Course: Suture Management and Intracorporeal Knotting which wil take place at JUMISC from 3 to 5 February under the Direction of Álvaro Serrano Pascual (Urology Service Specialist at the San Carlos Clinical Hospital, Madrid) and Francisco Miguel Sánchez Margallo (Deputy Scientific Director of NANBIOSIS)

It is a basic course of Laparoscopic Urology where the techniques of Laparoscopic Radical and Partial Nephrectomy will be carried out. The objective of this course is for specialists in Urology to improve their skills in suture management and intracorporeal knotting.

A step forward in the field of organic free radicals acting as chiral emitters

Researchers of NANBIOSIS U6. Biomaterial Processing and Nanostructuring Unit have just published the article titled “An enantiopure propeller ‐ like trityl ‐ brominated radical: Bringing together a high racemization barrier and an efficient circularly polarized luminescent magnetic emitter” in the scientific magazine Chemistry A European Journal.
The urgent need to cope with the more and more specific requirements in electronic devices is nowadays behind the search for new multifunctional materials. In this work, a step forward has been done in the field of organic free radicals acting as chiral emitters. The recently developed brominated trityl derivative, namely TTBrM radical, shows a satisfactory luminescent dissymmetry factor (|glum(592 nm)| ≈ 0.7 x 10-3) despite its pure organic nature. However, in contrast to its chlorinated homologues, no hints of racemization were observed up to 60 ° C for more than two hours, due to the higher steric hindrance imposed by the bulky Br atoms. Moreover, improved derivatives can be envisaged from this compound thanks to the wide possibilities that Br atoms at para-positions offer for further functionalization.
