Several papers in the BJPsych this month present findings that challenge accepted notions in psychiatry, and one paper focuses specifically on the extent to which the findings of highly cited papers are subsequently replicated. Tajika et al (pp. 357–362) identified highly cited studies claiming evidence of effective treatments reported in a range of high-impact general medical and psychiatric j...

Gunnell et al (pp. 298–305) investigate whether the established association between impaired intellectual performance and schizophrenia is due to the confounding influence of adverse prenatal and early childhood exposures on both intellectual development and the risk of schizophrenia. By studying a large cohort of Swedish male conscripts, results show that the association is not explained by ce...

In the title molecular salt, C(10)H(15)NH(3) (+)·C(7)H(5)O(2) (-), both carboxyl O atoms act as acceptors for strong N-H⋯O inter-molecular hydrogen-bond inter-actions with the ammonium group in the cation, generating infinite chains along the b axis. A weak C-H⋯π inter-action is also present.

In this communication, we demonstrate our recent finding that iron-substituted SBA-15 (Fe-SBA-15) microparticles possess intrinsic peroxidase-like activity and can catalyze the oxidation of peroxidase substrate 3,3',5,5'-tetramethylbenzidine (TMB) by H(2)O(2) to develop a blue color in aqueous solution, leading to a simple approach towards colorimetric detection of H(2)O(2) with a linear detect...

A new method for the preparation of well-defined functionalized mesoporous SBA-15 has been developed by a one-step co-condensation method using trimethallylsilanes as organosilane sources. This new method enables the incorporation of various bulky organic functional groups with long alkyl chain tethers into the mesoporous silica network.
