A new pseudo-tetrahedral Co(II) complex has been grafted onto the surface of SBA-15 and successfully utilized for the catalytic oxidization of alkylaromatic substrates with tert-butyl hydroperoxide (TBHP)via an H-atom transfer mechanism.

Fusarium graminearum Z-3639 and F. sporotrichioides NRRL3299 produce the trichothecene mycotoxins 15-acetyldeoxynivalenol and T-2 toxin, respectively. These toxins differ in oxygenation at C-4, C-7, and C-8. In F. sporotrichioides, Tri1 (FsTri1) controls C-8 hydroxylation. To determine the function of an apparent F. graminearum Tri1 (FgTri1) homolog, both FsTri1 and FgTri1 genes were heterologo...

The generation and maintenance of immunological memory requires the activation, expansion, and persistent proliferation of antigen-specific T cells. Recent work suggests that IL-15 may be important for this process. Surprisingly, we now find that expression of the high-affinity receptor for IL-15, IL-15R , on T cells is dispensable for the generation or maintenance of memory CD8 T cells. By con...

Background Interleukin-15 (IL-15) mediates the function of some innate and adaptive immune cells, which makes it an attractive target as an anti-cancer agent. Gene electrotransfer (GET) has been used to safely deliver plasmid DNA (pDNA) to tissues in a number of pre-clinical and clinical studies for cancer therapy. Previously we have shown using GET to deliver interleukin-15 (IL-15) to mouse me...

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...
