Abstract: Genetically identical cells sharing an environment can display markedly different phenotypes. It is often unclear how much of this variation derives from chance, external signals, or attempts by individual cells to exert autonomous phenotypic programs. By observing thousands of cells for hundreds of consecutive generations under constant conditions, we dissect the stochastic decision between a solitary, motile state and a chained, sessile state in Bacillus subtilis. We show that the motile state is 'memoryless', exhibiting no autonomous control over the time spent in the state. In contrast, the time spent as connected chains of cells is tightly controlled, enforcing coordination among related cells in the multicellular state. We show that the three-protein regulatory circuit governing the decision is modular, as initiation and maintenance of chaining are genetically separable functions. As stimulation of the same initiating pathway triggers biofilm formation, we argue that autonomous timing allows a trial commitment to multicellularity that external signals could extend..

Abstract: AIMS Alcohol is believed to be an important factor behind the sharp rise in mortality during the period 1990-94 in Russia. However, the rise in the standard alcohol consumption proxy does not seem to be sufficient to explain all the increase in mortality. This study adopts a novel approach to exploring the role of the alcohol factor in the increased mortality by investigating whether the mismatch between trends in mortality and recorded alcohol consumption is due to an underestimation of the consumption increase.
DESIGN AND MEASUREMENTS First, the alcohol effect on the male accident rate was estimated using data for the period 1959-89. Next, the estimated alcohol effect and the observed accident mortality rate for the period 1990-98 were used to backcast alcohol consumption during that period. Thirdly, the backcasted alcohol series was used to predict trajectories in alcohol poisoning mortality, the homicide rate and all-cause mortality during the period 1990-98.
FINDINGS There was a markedly stronger increase in the backcasted consumption proxy than in the standard alcohol consumption proxy during the period 1990-98. There was a substantial gap between the observed mortality rates and the rates predicted from the standard alcohol consumption proxy, whereas the predictions from the backcasted alcohol proxy were much closer to the target.
CONCLUSIONS Much of the rise in Russian mortality in 1990-94 appears to have been due to the increase in population drinking, but this increase is grossly underestimated by the commonly used consumption proxy combining alcohol sales, estimation of illicit alcohol production and proportion of alcohol-positive violent deaths..

Abstract: Arterial smooth muscle cells (SMCs) are arrested in the G1 phase of the cell cycle on polymerized type I collagen fibrils, while monomer collagen supports SMC proliferation. Cyclin E-associated kinase and cyclin-dependent kinase 2 (cdk2) phosphorylation are inhibited on polymerized collagen, and levels of the cdk2 inhibitors p27Kip1 and p21Cip1/Waf1 are increased compared with SMCs on monomer collagen. p27Kip1 associates with the cyclin E-cdk2-p21Cip1/Waf1 complex in SMCs on polymerized collagen. Monovalent blocking antibodies to alpha2 integrins, integrins that mediate adhesion to both forms of collagen, mimic these effects on monomer collagen. Furthermore, polymerized collagen rapidly suppresses p70 S6 kinase, a possible regulator of p27Kip1. Thus, fibrillar collagen specifically regulates early integrin signaling that may lead to up-regulation of cdk2 inhibitors and inhibition of SMC proliferation..
