In the past decade, product-related environmental regulations (PRERs) aimed at environmental protection and consumers’ health and safety were actively introduced in developed countries, led by the EU. This study examined the impact of two PRERs released by the EU—RoHS and REACH—on Malaysian and Vietnamese firms’ compliance. The first analysis focuses on the R&D enhancement effect of PRERs. We then consider productivity as a realization of innovations and examine if the R&D enhanced by PRERs can promote further productivity. The result shows that the response to REACH can create incentives to advance R&D. Further estimations on the effect of inducedR&Don firm productivity show a significant positive relationship between them. On the other hand, no relationship between the response to RoHS and R&D expenditure is found. Moreover, the analysis also shows that firms comply with RoHS and REACH in different ways, but just the ability to continue exporting to the EU motivates compliance.

A 75-year-old Japanese man with chronic hepatitis C was found to have a large liver tumor and multiple nodules in the bilateral lungs. We diagnosed the tumor as hepatocellular carcinoma (HCC) with multiple lung metastases based on imaging studies and high titers of HCC tumor markers. Remarkably, without any anticancer treatment or medication, including herbal preparations, the liver tumor decreased in size, and the tumor makers diminished. Moreover, after 1 year, the multiple nodules in the bilateral lungs had disappeared. Fifteen months after the first medical examination, transcatheter arterial chemoembolization (TACE) was performed for the residual HCC. Because local relapse was observed on follow-up computed tomography, a second TACE was performed 13 months after the first one. At 4 years after the second TACE (7 years after the initial medical examination), there was no recurrence of primary or metastatic lesions. Spontaneous regression of HCC is very rare, and its mechanism remains unclear. Understanding the underlying mechanism of this rare phenomenon may offer some hope of finding new therapies, even in advanced metastatic cases. (Gut Liver 2014;8:569-574)
