In this paper we analyze the characteristics of stakeholder engagement in small and medium-sized family enterprises (SMFEs). The paper aims to understand the reason, the meaning and the manner to involve stakeholders in this kind of firm. The stakeholder engagement has been linked with corporate social responsibility, stating that firm that take initiatives to engage its stakeholders can be described as socially responsible. This claim is not always acceptable because we have to understand when the different forms of stakeholder engagement are consistent with the concept of corporate social responsibility. The focus in SMFEs is justified, on the one hand, for its specific characteristics an…

Sigma-fragmentability and the property SLD in C(K) spaces

AbstractWe characterize two topological properties in Banach spaces of type C(K), namely, being σ-fragmented by the norm metric and having a countable cover by sets of small local norm-diameter (briefly, the property norm-SLD). We apply our results to deduce that Cp(K) is σ-fragmented by the norm metric when K belongs to a certain class of Rosenthal compacta as well as to characterize the property norm-SLD in Cp(K) in case K is scattered.

Religious plurality in the era of globalization is a necessity in the midst of cultural heterogeneity, religious expression and religion itself. Religious plurality has a very large potential and role in the process of integrating the development of the Indonesian nation in the future. However, on the other hand, religious plurality contains the potential for conflict and disintegration of the nation, because the dominance of the absolute truth claims of each religion so that emotions become the basis of interaction and communication. Therefore, communication becomes a pillar of religious harmony. To achieve religious harmony, this research uses a qualitative-descriptive method that puts wi…

Fabrication of quercetin and curcumin bionanovesicles for the prevention and rapid regeneration of full-thickness skin defects on mice

2013

In the present work biocompatible quercetin and curcumin nanovesicles were developed as a novel approach to prevent and restore skin tissue defects on chronic cutaneous pathologies. Stable and suitable quercetin- and curcumin-loaded phospholipid vesicles, namely liposomes and penetration enhancer-containing vesicles (PEVs), were prepared. Vesicles were made from a highly biocompatible mixture of phospholipids and alternatively a natural polyphenol, quercetin or curcumin. Liposomes were obtained by adding water, while PEVs by adding polyethylene glycol 400 and Oramix®CG110 to the water phase. Transmission electron microscopy, cryogenic-transmission electron microscopy and small- and wide-ang…

Intracellular distribution of the La antigen in CV-1 cells after herpes simplex virus type 1 infection compared with the localization of U small nucl…

1989

The La antigen is known to associate, at least transiently, with a series of small nuclear and cytoplasmic ribonucleoprotein particles (snRNPs and scRNPs), e.g. U1 and U6 snRNPs. In CV-1 cells a monoclonal antibody (MAb), directed against the La protein (La1B5), immunostained intranuclear speckles. These speckles were found to co-localize with speckles that were stained by MAbs directed against either all U snRNPs or only against U1 snRNPs. Two h after infection of CV-1 cells with herpes simplex virus type 1 (HSV-1) (strain HFEM) the staining of nuclear speckles with the anti-La MAb disappeared and the La protein was found quantitatively in the cytoplasm. In contrast nuclear speckles remain…

A DC and small signal AC model for organic thin film transistors including contact effects and non quasi static regime

2017

Abstract We present a compact model for the DC and small signal AC analysis of Organic Thin Film Transistors (OTFTs). The DC part of the model assumes that the electrical current injected in the OTFT is limited by the presence of a metal/organic semiconductor junction that, at source, acts as a reverse biased Schottky junction. By including this junction, modeled as a reverse biased gated diode at source, the DC model is able to reproduce the scaling of the electrical characteristics even for short channel devices. The small signal AC part of the model uses a transmission line approach in order to compute the impedances of the channel and parasitic regions of the device. The overlap capacit…

Chromatin remodeling regulation by small molecules and metabolites.

2010

The eukaryotic genome is a highly organized nucleoprotein structure comprising of DNA, histones, non-histone proteins, and RNAs, referred to as chromatin. The chromatin exists as a dynamic entity, shuttling between the open and closed forms at specific nuclear regions and loci based on the requirement of the cell. This dynamicity is essential for the various DNA-templated phenomena like transcription, replication, and repair and is achieved through the activity of ATP-dependent chromatin remodeling complexes and covalent modifiers of chromatin. A growing body of data indicates that chromatin enzymatic activities are finely and specifically regulated by a variety of small molecules derived f…

RNA mediated toll-like receptor stimulation in health and disease

2012

Besides their well known functions in storage and translation of information nucleic acids have emerged as a target of pattern recognition receptors that drive activation of innate immunity. Due to the paucity of building block monomers used in nucleic acids, discrimination of host and microbial nucleic acids as a means of self/foreign discrimination is a complicated task. Pattern recognition receptors rely on discrimination by sequence, structural features and spatial compartmentalization to differentiate microbial derived nucleic acids from host ones. Microbial nucleic acid detection is important for the sensing of infectious danger and initiating an immune response to microbial attack. F…

The glycosyltransferase activities of lysyl hydroxylase 3 (LH3) in the extracellular space are important for cell growth and viability.

2008

Abstract Lysyl hydroxylase (LH) isoform 3 is a post-translational enzyme possessing LH, collagen galactosyltransferase (GT) and glucosyltransferase (GGT) activities. We have demonstrated that LH3 is found not only intracellularly, but also on the cell surface and in the extracellular space, suggesting additional functions for LH3. Here we show that the targeted disruption of LH3 by siRNA causes a marked reduction of both glycosyltransferase activities, and the overexpression of LH3 in HT-1080 cells increases hydroxylation of lysyl residues and the subsequent galactosylation and glucosylation of hydroxylysyl residues. These data confirm the multi-functionality of LH3 in cells. Furthermore, t…

A comparative analysis to study editing of small noncoding BC200- and Alu transcripts in brain of prion-inoculated rhesus monkeys (M. Mulatta).

2012

Small retroelements (short interspersed elements, abbreviated SINEs) are abundant in vertebrate genomes. Using RNA isolated from rhesus monkey cerebellum and buffy coat, reverse-transcription polymerase chain reaction (RT PCR) was applied to clone cDNA of BC200 and Alu RNAs. Transcripts containing Alu-SINE sequences may be subjected to extensive RNA editing by ADAR (adenosine deaminases that act on RNA) deamination. Abundance of Alu transcripts was determined with real-time RT PCR and was significantly higher than BC200 (brain cytoplasmic) in cerebellum. BC200 transcripts were absent from buffy coat cells. Availability of the rhesus genome sequence allowed the BC200 transcripts to be mapped…
