The triumvirate of signaling molecules controlling Toxoplasma microneme exocytosis: Cyclic GMP, calcium, and phosphatidic acid

Plos.org 

by Hayley E. Bullen, Hugo Bisio, Dominique Soldati-Favre

To elicit effective invasion and egress from infected cells, obligate intracellular parasites of the phylum Apicomplexa rely on the timely and spatially controlled exocytosis of specialized secretory organelles termed the micronemes. The effector molecules and signaling events underpinning this process are intricate; however, recent advances within the field of Toxoplasma gondii research have facilitated a broader understanding as well...

The causal nexus between energy consumption, carbon emissions and economic growth: New evidence from China, India and G7 countries using convergent cross mapping

Plos.org 

by Huajun Liu, Mingyu Lei, Naixin Zhang, Guangjie Du

Understanding the causality between energy consumption, carbon emissions and economic growth is helpful for policymakers to formulate energy, environmental and economic policies. For the first time, based on nonlinear dynamics, this paper employs multispatial convergent cross mapping (CCM) to revisit the energy-carbon-economy causation for China, India and the G7 countries using both aggregate data and per capita data. The findings indicate... Читать дальше...



Development and validation of an experience of time alone scale for borderline personality disorder

Plos.org 

by Yvette Vardy, Nicholas J. S. Day, Brin F. S. Grenyer

Background/Objective

Intolerance of aloneness is considered a core feature of borderline personality disorder (BPD) that is clinically significant, yet under-researched. This study developed a measure of aloneness for individuals with BPD.

Method

Interviews investigating the experience of aloneness for BPD participants (n = 12) formed the basis for the development of the measure. Pilot testing then occurred with BPD participants... Читать дальше...

Transcripts with systematic nucleotide deletion of 1-12 nucleotide in human mitochondrion suggest potential non-canonical transcription

Plos.org 

by Ganesh Warthi, Hervé Seligmann

Raw transcriptomic data contain numerous RNA reads whose homology with template DNA doesn’t match canonical transcription. Transcriptome analyses usually ignore such noncanonical RNA reads. Here, analyses search for noncanonical mitochondrial RNAs systematically deleting 1 to 12 nucleotides after each transcribed nucleotide triplet, producing deletion-RNAs (delRNAs). We detected delRNAs in the human whole cell and purified mitochondrial transcriptomes, and... Читать дальше...

The relationship between attentional processing of emotional information and personality: A comparison between older and younger adults

Plos.org 

by Priska Steenhaut, Ineke Demeyer, Gina Rossi, Rudi De Raedt

Older adults have been found to focus more on positive and less on negative information compared to younger adults. Yet, results on this attentional positivity effect are inconsistent. Since personality has been related to attentional processing in younger adults, we explored whether (mal)adaptive personality traits are also linked to the occurrence of the positivity effect measured with eye tracking paradigms. We performed two... Читать дальше...

Nitrogenous compounds characterized in the deterrent skin extract of migratory adult sea lamprey from the Great Lakes region

Plos.org 

by Amila A. Dissanayake, C. Michael Wagner, Muraleedharan G. Nair

The sea lamprey (Petromzons marinus) is a devastating invasive species that represents a significant impediment to restoration of the Laurentian Great Lakes. There is substantial interest in developing environmentally benign control strategies for sea lamprey, and many other aquatic invasive species, that employ the manipulation of semiochemical information (pheromones and chemical cues) to guide the movements of invaders into control opportunities (e.g. traps...

Comparative study on the efficacy of sodium hypochlorite, aqueous ozone, and peracetic acid in the elimination of Salmonella from cattle manure contaminated various surfaces supported by Bayesian analysis

Plos.org 

by Ameer Megahed, Brian Aldridge, James Lowe

Providing the dairy industry with an effective and safe disinfectant is considered a key step in improving the farm hygiene and biosecurity. Salmonella infection via foodborne transmission remains a major public health threat. The main objective of this study was therefore to characterize and compare the decontamination power of NaOCl, aqueous-O3, and PAA against cattle manure based-Salmonella heavily contaminated various surfaces (plastic, nylon, rubber, and wood) using Bayesian analysis.

Shift from primary pneumonic to secondary septicemic plague by decreasing the volume of intranasal challenge with Yersinia pestis in the murine model

Plos.org 

by Rachel M. Olson, Deborah M. Anderson

Yersinia pestis is the causative agent of pneumonic plague, a disease involving uncontrolled bacterial growth and host immunopathology. Secondary septicemic plague commonly occurs as a consequence of the host inflammatory response that causes vasodilation and vascular leakage, which facilitates systemic spread of the bacteria and the colonization of secondary tissues. The mortality rates of pneumonic and septicemic plague are high even when antibiotics are administered. Читать дальше...
