Abstract
BACKGROUND Cure of lung cancer is impossible without local tumour control. This can be compromised by accelerated repopulation of tumour cells during radiotherapy and chemotherapy. A strategy to minimise accelerated repopulation might improve local control. We investigated whether concurrent chemo-radiotherapy could be given safely over four weeks. METHODS We conducted a randomised phase II trial in which patients with inoperable Stage III Non-Small Cell Lung Cancer (NSCLC) received a radical radiation dose over four weeks rather than conventional fractionation. Treatment was given either sequentially or concurrently with three to four cycles of cisplatinum and vinorelbine. 130 patients with inoperable stage III NSCLC and PS 0-1 were randomised to receive cisplatinum and vinorelbine with either sequential or concurrent chemo-radiation using 55Gy in 20 fractions over four weeks. The primary end-point was treatment related mortality. Secondary end-points were toxicity and survival. FINDINGS Treatment related mortality was: 2.9% (exact 95% confidence interval [CI] 0.36-10.2%) and 1.7% (exact 95% CI 0.043-9.1%) for the Concurrent and Sequential group respectively; relative risk (RR) 1.25; (95% CI 0.55, 2.84). Toxicity was similar between arms; grade 3 or worse oesophagitis was 8.8% versus 8.5%; RR 1.02 (95% CI 0.58, 1.79). OS HR was 0.92; 95% CI (0.60-1.39; p=0.682). The 2 year overall survival rates were: 50% versus 46%; RR 1.06 (95% CI 0.77, 1.46) for Concurrent versus Sequential. INTERPRETATION A strategy to minimise the effects of accelerated repopulation using accelerated hypofractionated radiotherapy with chemotherapy is feasible, and reasonably safe for patients with stage III NSCLC. The reported two year survival is promising and suggests that a four week regime of radiotherapy should be compared with conventionally fractionated radiotherapy in an adequately powered randomised controlled phase III trial.

Abstract
Peripartum hormones and sensory cues from young modify the maternal brain in ways that can render females either at risk for, or resilient to, elevated anxiety and depression. The neurochemical systems underlying these aspects of maternal emotional and mood states include the inhibitory neurotransmitter GABA and the neuropeptide oxytocin (OXT). Data from laboratory rodents indicate that increased activity at the GABA(A) receptor contributes to the postpartum suppression of anxiety-related behaviour that is mediated by physical contact with offspring, whereas dysregulation in GABAergic signalling results in deficits in maternal care, as well as anxiety- and depression-like behaviours during the postpartum period. Similarly, activation of the brain OXT system accompanied by increased OXT release within numerous brain sites in response to reproductive stimuli also reduces postpartum anxiety- and depression-like behaviours. Studies of peripartum women are consistent with these findings in rodents. Given the similar consequences of elevated central GABA and OXT activity on maternal anxiety and depression, balanced and partly reciprocal interactions between these two systems may be essential for their effects on maternal emotional and mood states, in addition to other aspects of postpartum behaviour and physiology.

Abstract
OBJECTIVE Vascular smooth muscle cell (VSMC) apoptosis occurs at low levels in atherosclerotic plaques and in vessel remodeling; however, the consequences and mediators of these levels are not known. Akt1 protects against VSMC apoptosis largely through inactivating target proteins such as forkhead class O transcription factor 3a (FoxO3a), but Akt1 signaling is reduced and FoxO3a activity is increased in human atherosclerosis. We therefore sought to determine whether inhibition of VSMC apoptosis via Akt1 activation regulates vessel remodeling and atherogenesis and to identify FoxO3a target proteins that mediate VSMC apoptosis. APPROACH AND RESULTS We generated mice that express an Akt1 protein that can be activated specifically in arterial VSMCs. Akt1 activation did not affect normal arteries, but inhibited VSMC apoptosis and negative remodeling after carotid ligation, indicating that VSMC apoptosis is a major determinant of vessel caliber after changes in flow. Akt1 activation inhibited VSMC apoptosis during atherogenesis and increased relative fibrous cap area in plaques. Microarray studies identified multiple FoxO3a-regulated genes involved in VSMC apoptosis, including apoptotic protease activating factor 1 as a novel target. Apoptotic protease activating factor 1 mediated the proapoptotic activity of FoxO3a, was increased in human atherosclerosis, but reduced by Akt1 activity in vivo. CONCLUSIONS Akt1 is a major regulator of VSMC survival in vivo during vessel remodeling and atherogenesis, mediated in large part through inhibition of FoxO3a and its downstream genes, including apoptotic protease activating factor 1. Our data suggest that even the low-level VSMC apoptosis seen during changes in flow determines vessel wall structure and promotes fibrous cap thinning during atherogenesis.
