High-purity solid parahydrogen.

Alkali atoms trapped in solid hydrogen matrices have demonstrated ultralong electron spin coherence times and are promising as quantum sensors. Their spin coherence is limited by magnetic noise from naturally occurring orthohydrogen molecules in the parahydrogen matrix. In the gas phase, the orthohydrogen component of hydrogen can be converted to parahydrogen by flowing it over a catalyst held at cryogenic temperatures, with lower temperatures giving a lower orthohydrogen fraction.

Sexual addiction in drug addicts: The impact of drug of choice and poly-addiction.

Objective:: To compare the risk of comorbid sexual addiction in a sample of individuals with a diagnosis of substance dependence, stratifying the sample by drug of choice as well as by mono versus polysubstance addiction.

Guidelines of the Brazilian Association of Studies on Alcohol and Other Drugs (ABEAD) for diagnosis and treatment of psychiatric comorbidity with alcohol and other substance and dependence.

In recent years, several studies have been focused on the comorbidity of psychiatric disorders with alcohol and other substance dependence. In this context, the Brazilian Association of Studies on Alcohol and Other Drugs initiated a project to establish Brazilian Guidelines. The aim of this study was to review diagnostic and therapeutic criteria for the most prevalent psychiatric comorbidities.

The social adjustment of people with severe mental illness in São Paulo, Brazil.

Objective: To investigate the social adjustment of individuals with severe mental illness living in the community in a large urban center of a developing country, and the characteristics associated with poor social functioning.

Method: A cross-sectional study was performed in the city of Sao Paulo. Eligible subjects were residents of a defined geographic area, aged between 18 and 65, with a diagnosis of functional psychosis who had had contact with any public psychiatric service during a defined period.

Prevalence of substance misuse among individuals with severe mental illness in São Paulo.

Objectives: The aims of this study were to estimate the prevalence of substance misuse among people with severe mental illness in a large urban centre of a developing country, and to investigate which are the individual characteristics associated with such comorbidity.

Method: A cross-sectional study was carried out in São Paulo, Brazil, with all mental health services that covered a defined geographical area. Eligible individuals had had any contact with such mental health services, had clinical diagnoses of functional psychoses, and were resident in the areas defined for the study.

The spontaneous return of sensibility in breasts reconstructed with autologous tissues.

Some spontaneous return of sensibility following autologous tissue breast reconstruction is often suspected but not well documented. In the present study, objective touch-pressure, pain, temperature, and vibratory sensibilities were recorded in 33 autologous breast reconstructions at an average of 25.2 months postoperatively.
