Identification ofCandida albicansclinical isolates by PCR amplification of anEFB1gene fragment containing an intron-interrupted open reading frame

2000

The use of a single pair of primers, deduced from the intron and exon nucleotide sequences of the Candida albicans EFB1 gene, in polymerase chain reaction (PCR) assays performed with whole cells of both laboratory strains and clinical isolates of Candida species, resulted in the species-specific amplification of a 785 bp DNA fragment in C. albicans strains. Clinical C. albicans isolates were tested, and 85 out of 86 generated the expected PCR-amplified product; other Candida species, both laboratory strains and clinical isolates, as well as laboratory strains belonging to other fungal genera, including medically relevant taxa, failed to amplify any DNA fragment. In addition, unusual C. albi…

Isolation and characterization of Urbain, a 20-hydroxyecdysone-inducible gene expressed during morphogenesis of Bombyx mori wing imaginal discs.

1995

In insects, wing imaginal discs respond to the steroid hormone 20-hydroxyecdysone by initiating morphogenesis leading to the formation of the adult flight appendages. In this work we analyse the expression of a Bombyx gene, referred to as Urbain, whose cDNA had been previously isolated from wing discs (Chareyre et al. 1993). Accumulation of the 1.8 kb transcript occurs concomitantly with the increase of 20-hydroxyecdysone titer at every stage examined during post-embryonic development. In vitro, its accumulation is delayed 6–9 h after exposure to 20-hydroxyecdysone. Studies in the presence of cycloheximide have established that Urbain is a secondary response gene. The sequence of the mRNA c…

Identification of highly conserved genes: SNZ and SNO in the marine sponge Suberites domuncula: their gene structure and promoter activity in mammali…

2001

Abstract Recently, we reported that cells from the sponge Suberites domuncula respond to ethylene with an increase in intracellular Ca 2+ level [Ca 2+ ] i , and with an upregulation of the expression of (at least) two genes, a Ca 2+ /calmodulin-dependent protein kinase and the potential ethylene-responsive gene, termed SDSNZERR (A. Krasko, H.C. Schroder, S. Perovic, R. Steffen, M. Kruse, W. Reichert, I.M. Muller, W.E.G. Muller, J. Biol. Chem. 274 (1999)). Here, we describe for the first time that also mammalian (3T3) cells respond to ethylene, generated by ethephon, with an immediate and transient, strong increase in [Ca 2+ ] i . Next, the promoter for the sponge SDSNZERR gene was isolated …

La religión del cuerpo-mercancía: ¿un nuevo opio del pueblo?

2018

The commercial exploitation or more precisely the total capitalist management of the human body erects this as a universal divinity. The direct consequence of this generalized corporal capitalism is the massive depoliticization of the body and, often, the reflection that is dedicated to it. In this article, we seek to reflect on the current practices of bodily modifications within the framework of the changes in the regimes of neoliberal governance in recent decades. This reflection is guided by the revision of central texts of critical theory

A systematic literature review on cyberstalking : An analysis of past achievements and future promises

2020

Individuals’ excessive use of technology-enabled communication platforms, such as social media, has led to scholarly recognition of rising incidences of cyberstalking. Despite considerable studies directed at its examination, the current research on cyberstalking is limited by a lack of clarity on its characterization and prevalence, coupled with a fragmented research focus. To address this limitation, a Systematic Literature Review (SLR) on cyberstalking has been undertaken. Rigorous protocols were applied to identify 49 empirical studies via Scopus and Web of Science, based on specific keywords and article selection criteria. Findings reveal four emergent research themes on characteristic…

Don't throw away your printed books: A meta-analysis on the effects of reading media on reading comprehension

2018

Abstract With the increasing dominance of digital reading over paper reading, gaining understanding of the effects of the medium on reading comprehension has become critical. However, results from research comparing learning outcomes across printed and digital media are mixed, making conclusions difficult to reach. In the current meta-analysis, we examined research in recent years (2000–2017), comparing the reading of comparable texts on paper and on digital devices. We included studies with between-participants (n = 38) and within-participants designs (n = 16) involving 171,055 participants. Both designs yielded the same advantage of paper over digital reading (Hedge's g = −0.21; dc = −0.2…

Outlining the impact of intellectual capital accumulation and depletion processes on the performance of an insurance firm: a dynamic resource-based p…

2014

This paper aims to develop a conceptual framework on how Intellectual Capital (IC) accumulation and depletion processes are dynamically interrelated with firm performance. Such a framework makes explicit the relationships between policy levers, strategic resources, drivers, end-results and performance indicators through a Dynamic Resource-based perspective. Such an approach matches the Resource based perspective and the System Dynamics (SD) methodology. This paper argues that in order to explain a firm superior performance, it is not sufficient to look at the endowment of strategic resources in a given moment of time; it is instead required to investigate the dynamics of company strategic r…

Use of hierarchical Bayesian framework in MTS studies to model different causes and novel possible forms of acquired MTS

2015

Abstract: An integrative account of MTS could be cast in terms of hierarchical Bayesian inference. It may help to highlight a central role of sensory (tactile) precision could play in MTS. We suggest that anosognosic patients, with anesthetic hemisoma, can also be interpreted as a form of acquired MTS, providing additional data for the model.

Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. The observer wore a head-mounted display (HTC Vive) and was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, an…

Learning from Errors: Detecting ZigBee Interference in WiFi Networks

2014

In this work we show how to detect ZigBee interference on commodity WiFi cards by monitoring the reception errors, such as synchronization errors, invalid header formats, too long frames, etc., caused by ZigBee transmissions. Indeed, in presence of non-WiFi modulated signals, the occurrence of these types of errors follows statistics that can be easily recognized. Moreover, the duration of the error bursts depends on the transmission interval of the interference source, while the error spacing depends on the receiver implementation. On the basis of these considerations, we propose the adoption of hidden Markov chains for characterizing the behavior of WiFi receivers in presence of controlle…
