Tryptophanol-derived oxazoloisoindolinone fluorescent probes for cellular localization studies of p53 activators.

The protein p53 is a transcription factor with several key roles in cells, including acting as a tumour suppressor. In most human cancers its tumour suppressor function is inactivated, either through inhibition by negative regulators or by mutation in the TP53 gene. Thus, there is a high interest in developing molecules able to activate p53 tumour suppressor activity.

Custody and Psychiatric Treatment Hospitals in the prison system: A social death decreed?

This text discusses people with mental disorders in conflict with the law in Brazil and the Custody and Psychiatric Treatment Hospitals, institutions included in the prison system and considered a hybrid between health and justice. When we present the reality in the national context, we show that the Psychiatric Reform did not reach these institutions, and these individuals continue to be stigmatized, and their human rights are violated. We substantiate the need to advance the debate and raise some questions to establish new solutions to tackle the issue and ensure well-structured, scientific evidence-based health care.

The use of epifluorescence microscopy and fluorescent dyes for visualization of Oxyuris equi eggs.

This study presents a new method for visualization of Oxyuris equi eggs collected by means of a clear adhesive tape applied to the perianal region of horses. The obtained results indicate that this protocol permits a quick, easy, clear and selective visualization of Oxyuris equi eggs even in the presence of feces and other material. Another advantage of this method is that it can be used with fluorescent dyes solubilized in water, which will stain biologic material without dissolving or altering the adhesive tape and is also environmentally safe.

A new methodology for the visualization of latent fingermarks on the sticky side of adhesive tapes using novel fluorescent dyes.

Three novel fluorescent dyes were evaluated for the detection of latent fingermarks on different types and colors of adhesive tapes. Compared with the conventional reagents used to reveal latent fingermarks on these surfaces, these new fluorescent dyes have many advantages. They are highly selective to fingermarks, require only a simple procedure, do not need pre- or post-treatment, have high thermal and photochemical stability, are low in cost and use only water as a solvent.

Olanzapine for recurrent excessive irritability and psychotic symptoms after mesial temporal lobectomy in a patient with temporal lobe epilepsy.

We report the case of a patient with temporal lobe epilepsy, nonresponsive to antiepileptic drugs, who became seizure-free, but developed recurrent excessive irritability and psychotic symptoms after successful mesial temporal lobectomy. This patient was refractory to various pharmacological treatments including antipsychotics, mood stabilizers, and benzodiazepines before being successfully treated with olanzapine.
