London, Oct 24 : Psychiatrist and broadcaster Raj Persaud has left his job at a leading hospital four months after being convicted of dishonesty by a disciplinary tribunal.

Persaud, who has lost media commissions after admitting plagiarism at a General Medical Council hearing in June, has stepped down as a consultant psychiatrist for the South London and Maudsley NHS trust.

The move follows talks with trust officers this month when he was legally cleared to return to work after being struck off for three months by the GMC.

The tribunal criticised him so heavily that there was widespread doubt that he would return to consultant status, The Guardian reported.

A spokesman for the Maudsley confirmed that Persaud had left.

US researchers say hydrogen sulfide, known for its bad smell is important for regulating our blood pressure. According to the study published in Science, researchers at John Hopkins University, in Maryland found that hydrogen sulfide; a toxic gas responsible for the foul odor of flatulence is also produced by an enzyme called CSE in the thin lining of the blood vessels. This regulates blood pressure by relaxing the blood vessels.

Guangdong Yang, PhD, of the University of Saskatchewan and Lakehead University in Canada, and colleagues examined two groups of mice in the study. One group of mice was normal while the second group of mice had been engineered to not have CSE, an enzyme long suspected of making hydrogen sulfide.
