Professor Peter Kraft at Harvard TH Chan School of Public Health, USA, says: «Given the size of these studies, we expected that we would find a lot of new breast cancer risk variants, but the studies tells us a lot more about which genes are involved, revealing many previously unsuspected genes and genetic mechanisms underlying breast carcinogenesis.

Most analytical approaches to this problem are rather rudimentary and involve calculating simple correlations among the genes whose expression changes in response to a perturbation, clustering the genes by molecular or known functional class, and drawing crude inferences about mechanism on that basis.

In this new paper, the researchers reveal more about that mechanism, showing that without the protective ability of BRCA1, breaks in the DNA strands go unfixed, prompting the molecule ATM kinase to activate a cellular «suicide» pathway involving a protein called p53.

«We know relatively little about the behavioral or ecological mechanisms that allow these induced defenses to be effective,» says Richard Karban, an ecologist at the University of California, Davis, who was not involved in the work.

«Understanding the mechanisms involved in regulating insulin is important and therefore helps us to better understand the pathophysiology of diabetes,» says Claret, who emphasizes that «much research needs to be done to apply these findings, given that we are talking about neural mechanisms of complex intervention.»

«These results suggest that phytoestrogens can interfere with the normal estrogen feedback mechanisms with respect to release of gonadotropin in the ewe... although most studies into the effects of phytoestrogens have concentrated on changes in the reproductive tract, there are indications that they interfere with the hormone balance between the ovaries and the hypothalamo - adenohypophysical system... ewes on phytoestrogens have shown follicular abnormalities such as numerous small follicles, deficient antrum formation and signs of early atresia... it is possible that the permanent changes brought about by phytoestrogens in the brain are a result of these compounds interacting with estrogen receptors in this tissue, and subsequently influencing the re-synthesis or replenishment of cyto - plasmic estrogen receptors... phytoestrogens can interfere with the delicate feedback mechanisms involved in the release of the gonadotrophins.»

A point I have been trying to get across is that it's not about believing in AGW, it's about understanding the mechanisms involved.

Please be precise about the mechanisms, volumes and timescales, just saying ocean circulations is not good enough, given what we know about the very long timescales involved to move the water.

A lot of people have different positions in the AGW debate, and with so many people and so much uncertainty particularly about the mechanisms and rate constants of all of the kinetic processes involved, I find it implausible that people would waste time on the simple comparisons, making much sound and fury, when it starts out with a short term comparison of CO2 and temperature over the same last few years.

They come up with all kinds of hypothetical feedback mechanisms involving more natural aerosol emissions in response to global warming: Dimethylsulfide from marine phytoplankton (although a very intriguing possibility, this has never been confirmed to be a significant feedback mechanism, and there is ample evidence to the contrary, which is omitted from the report), biological aerosols (idem), carbonyl sulfide (idem), nitrous oxide (idem), and iodocompounds (idem), about which they write the following: «Iodocompounds — created by marine algae — function as cloud condensation nuclei, which help create new clouds that reflect more incoming solar radiation back to space and thereby cool the planet.»

«[T] he science to me — and I have been involved, not as a scientist but as a lawyer — the science to me suggests, in the ten years I've been involved in it, that there is no basis, no mechanism that anybody can point to or look at to say that more CO2 in the air is going to lead to catastrophic global warming or apocalyptic global warming, as opposed to some mild warming, which is nothing to be concerned about at all.

Another meta - analysis reached similar conclusions about the equivalence of CBT and BT1 and a recent large - scale clinical trial of BT showed that it was as effective as antidepressant medication for depression.3 While BT and CBT were equally as effective for lower - levels of depression severity, patients with severe depression specifically benefited more from BT than CBT.3 Behavioural activation, which involves graded activity and goal scheduling, is the central component of BT for depression and may be related to a more general mechanism of change that is operating in many different treatments for depression, especially CBT.

Membership in a single - parent family or stepfamily is associated with increased levels of significant behavioral, emotional, and academic problems in children.1, 2 The mechanisms underlying this connection are likely to involve, among other factors, financial adversity, increased stress directly related to family transitions, and increased exposure to additional psychosocial risks.3, 4 Compared with the extensive research base connecting family type (ie, membership in a 2 - parent biological family, stepfamily, or single - parent family) and children's psychological adjustment, little is known about the physical health consequences of membership in diverse family types.

These questions can be divided into three categories: (1) questions about cross-sectional specificity, (2) questions about longitudinal specificity, and (3) more complex questions about developmental specificity, which involve questions about bidirectional associations and possible mechanisms for the aggravation of difficulties.
