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.

The absorption coefficient ( μ a ) and reduced scattering coefficient ( μ' s ) of flesh and skin of kiwifruit samples, which were treated with N -(2-chloro-4-pyridyl)- N ′-phenylurea (CPPU, a plant growth regulator) at the concentrations of 0, 5, 10, and

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.

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 ...

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 strategy.

Curcumin, the active ingredient of turmeric (Curcuma longa) used in culinary and medical practices in Asia, has immense potential for being used in cancer chemotherapy because of its control over the cell growth regulatory mechanisms. The present chapter throws light on the role of curcumin in modulating the various phases of the cell cycle and its ...

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 ...

Melatonin: A New Plant Hormone and/or a Plant Master Regulator?
Trends in Plant Science, 2019Melatonin is a pleiotropic molecule with many diverse actions in plants. It is considered primarily an antioxidant with important actions in the control of reactive oxygen and nitrogen species (ROS and RNS), among other free radicals, and harmful ...
