FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells
FEBS Open Bio, EarlyView.RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Economics Letters, 2006
Using objective measures of business regulation in 135 countries, we establish that countries with better regulations grow faster. Improving from the worst quartile of business regulations to the best implies a 2.3 percentage points increase in annual growth.

Current Opinion in Genetics & Development, 1992
The proliferation of cells is regulated by countervailing positively- and negatively-acting signaling networks. The anti-proliferative signals, the study of which has been much neglected until recently, are often conveyed by growth-inhibitory peptides.

Neuropeptides as growth regulators
British Medical Bulletin, 1989The classical role of neuropeptides as fast-acting neurohumoral signallers has recently been challenged by the discovery that many neuropeptides are also growth factors stimulating slow-acting mitogenesis. Their mechanisms of action have been studied in cell culture, and their cell-surface receptors have been characterized pharmacologically using ...

Regulation of Growth by Negative Growth Regulators
1989The concept of growth regulation by endogenous inhibitors was first suggested by studies on wound healing and carcinogenesis (see Wang and Hsu, 1986). This area of research has long suffered from the fact that purification of specific compounds that inhibited cell proliferation (or differentiation) of normal cells proved elusive.

Capital & Class, 2013
De-growth theses point to a renewal of critical thinking able to link intellectual research projects and social movements. This paper provides an overview of some of the strands of arguments that are mobilised to criticise the ‘growth obsession’, and explains why issues raised by de-growth proponents are at odds with the regulationist research ...

The Growth Regulation of Keratinocytes
The Journal of Dermatology, 1992Taken together, all these results suggest that TGF-alpha and amphiregulin are the major growth factors for positive growth control, although we don't know which plays the central role. For negative growth control, TGF-beta is the major factor. However, it remains to be solved which isoform of TGF-beta is naturally involved in keratinocyte growth ...

Growth Factors and Regulation of Cell Growth
Annual Review of Medicine, 1982A new class of polypeptide hormones known collectively as growth factors has been identified. These polypeptides are able to stimulate DNA synthesis and mitosis of cells cultured in vitro. Growth factors have been isolated from several sources, including platelets, submaxillary glands, pituitary, brain, and medium conditioned by cells grown in vitro ...

Growth regulation by nerve growth factor
Molecular and Cellular Biochemistry, 1979Although a great deal of descriptive information has been obtained about the actions of nerve growth factor on its target tissues, its structure, its receptors, and even its biosynthesis, there is no clear understanding, as yet, of the intracellular events mediating its transcriptional involvements.
