Brief observations of the behavior of males of the dynastine beetle Ageopsis nigricollis suggest that the males use their horns as weapons in intraspecific fights. Mea surements of nearly 200 males show that there are two different morphs. Thoracic but not head horns are missing in the minor morph, and behavioral observations confirm that thoracic horns are less useful for smaller individuals. ...

Biodegradation of xenobiotic compounds is examined with s-triazines as an example and with biological treatment of wastewater containing striazines as an aim. s-Triazines have been termed recalcitrant, but examination of the literature indicates that a potential for biodegradation exists. Ni t rogenl imi ted enr ichment cultures yield organisms able to degrade by-products of the industrial synt...

This paper mmmarirrs the experimental program, rhe modal fesl results, the exrrocred modal shapes and an m&is implemented to localize the damage via modal strain energy distribution. The modal kw results consist of lhe vibrational signatures due m df&enr damages on rhe s,ruc,ure. The exrracted modal results are impiernenred in a global damqe detecrion/eualuation theory bared on modal swain ener...

In the context of television consumption and its opportunity costs the question arises how far experiencing mere representations of the outer world would have the same neural and cognitive consequences than actively interacting with that environment. Here we demonstrate that physical interaction and direct exposition are essential for the beneficial effects of environmental enrichment. In our e...

Neuronal differentiation in the vertebrate nervous system is temporally and spatially controlled by mechanisms which are largely unknown. Here we investigate the role of XBF-1, an anterior neural plate-specific winged helix transcription factor, in controlling the pattern of neurogenesis in Xenopus ectoderm. We show that, in the anterior neural plate of normal embryos, prospective neurogenesis ...

My first duty is to thank you for the honour you have conferred on me in eleC| and installing me as your President. I am aware that there are a number contemporary colleagues who would fill this high office much more ably than I, a feel therefore, that my adornment with this handsome Badge of Office is in pa^' all events, a compliment to my specialty, and so, unworthy as I am, I felt strained t...

BACKGROUND Schizophrenia is a heterogeneous disorder in terms of patient response to antipsychotic treatment. Understanding the heterogeneity of treatment response may help to guide treatment decisions. This study was undertaken to capture inherent patterns of response to antipsychotic treatment in patients with schizophrenia, characterize the subgroups of patients with similar courses of respo...

The cytoplasmic tyrosine kinase Yes has previously been shown to have an important role in maintaining mouse and human embryonic stem (ES) self-renewal through an unknown pathway downstream of leukemia inhibitory factor (LIF) and one or more factors in serum. Here, we show that TEAD2 and its transcriptional co-activator, the Yes-associated protein YAP, co-operate in a signaling pathway downstre...
