TL;DR: In this article, the role of cultural barriers in the relationship between open-mindedness and organizational innovation is examined through an empirical investigation of 133 small and medium-sized enterprises (SMEs).
Abstract: Purpose – There is no empirical evidence, particularly in relation to small and medium‐sized enterprises (SMEs), to support the concept of cultural barriers and how they relate to open‐mindedness (OM). Some of these cultural barriers can be linked to outdated knowledge, which can impede the adoption of new configurations. The purpose of this paper therefore is to test the role of cultural barriers in the relationship between OM and organizational innovation.Design/methodology/approach – These relationships are examined through an empirical investigation of 133 SMEs.Findings – The results show that the relationship between OM and organizational innovation is likely to suffer if a firm does not overcome previously its cultural barriers. An explanation for this could be thatoutdated knowledge can impede the adoption of new configurations. Therefore, it is important for organizations to provide an appropriate environment for overcoming cultural barriers. Otherwise new knowledge will not be acted on or incorpo...

TL;DR: It is suggested that valproate protects against low-K+-induced apoptosis by acting in the phosphatidylinositol 3-kinase/protein kinase B pathway, and the protection by Li+ is independent of this transduction pathway.
Abstract: Acute treatment with valproate and Li+ was found to protect cultured cerebellar granule cells against apoptosis induced by low K+ (5 mM). Because the protection was unaffected by MK801 (N-methyl-D-aspartate receptor inhibitor), an increase in glutamate release cannot be responsible for the observed neuroprotection. Insulin also protects against low-K+-induced apoptosis of cerebellar granule cells. This protection is totally dependent on LY294002 (a phosphatidylinositol 3-kinase inhibitor). These results suggest a role for phosphatidylinositol 3-kinase in the neuroprotection induced by insulin. Likewise, and in contrast with the results observed with Li+, the protection induced by valproate is also dependent on insulin and LY294002. Moreover, valproate (a branched-chain fatty acid) does not change the plasma membrane microviscosity under physiological conditions. These results suggest that valproate protects against low-K+-induced apoptosis by acting in the phosphatidylinositol 3-kinase/protein kinase B pathway. The protection by Li+ is independent of this transduction pathway.

TL;DR: The current knowledge of ER–mitochondria signaling and the recent evidence concerning damage to this signaling in PD are summarized.
Abstract: Mitochondria form close physical contacts with a specialized domain of the endoplasmic reticulum (ER), known as the mitochondria-associated membrane (MAM). This association constitutes a key signaling hub to regulate several fundamental cellular processes. Alterations in ER-mitochondria signaling have pleiotropic effects on a variety of intracellular events resulting in mitochondrial damage, Ca2+ dyshomeostasis, ER stress and defects in lipid metabolism and autophagy. Intriguingly, many of these cellular processes are perturbed in neurodegenerative diseases. Furthermore, increasing evidence highlights that ER-mitochondria signaling contributes to these diseases, including Parkinson's disease (PD). PD is the second most common neurodegenerative disorder, for which effective mechanism-based treatments remain elusive. Several PD-related proteins localize at mitochondria or MAM and have been shown to participate in ER-mitochondria signaling regulation. Likewise, PD-related mutations have been shown to damage this signaling. Could ER-mitochondria associations be the link between pathogenic mechanisms involved in PD, providing a common mechanism? Would this provide a pharmacological target for treating this devastating disease? In this review, we aim to summarize the current knowledge of ER-mitochondria signaling and the recent evidence concerning damage to this signaling in PD.
