Shifting as a key executive function underlying cognitive restructuring for individuals with elevated social anxiety.

Psychol Psychother 2021 Jun 9;94(2):217-230. Epub 2020 Aug 9.

School of Psychology, Western Sydney University, Sydney, Australia.

Objectives: Previous studies have examined the relationship between executive functions and performance on cognitive behavioural therapy (CBT) tasks, such as cognitive restructuring. However, previous studies have used samples of older adults and only traditional measures of executive functions involving non-emotional stimuli. This study extends previous research to examine the specific executive function of shifting with regard to non-emotional and emotional stimuli and its relationship with cognitive restructuring, in a sample of young to middle-aged adults with elevated social anxiety.

Computationally guided in-vitro vascular growth model reveals causal link between flow oscillations and disorganized neotissue.

Commun Biol 2021 May 10;4(1):546. Epub 2021 May 10.

Department of Biomedical Engineering, Eindhoven University of Technology, Eindhoven, The Netherlands.

Disturbed shear stress is thought to be the driving factor of neointimal hyperplasia in blood vessels and grafts, for example in hemodialysis conduits. Despite the common occurrence of neointimal hyperplasia, however, the mechanistic role of shear stress is unclear. This is especially problematic in the context of in situ scaffold-guided vascular regeneration, a process strongly driven by the scaffold mechanical environment. Read More

Associative learning requires Neurofibromin to modulate GABAergic inputs to Drosophila Mushroom Bodies.

J Neurosci 2021 May 7. Epub 2021 May 7.

Institute for Fundamental Biomedical Research, Biomedical Sciences Research Centre "Alexander Fleming", Vari, 16672, Greece

Cognitive dysfunction, is among the hallmark symptoms of Neurofibromatosis 1, and accordingly, loss of the ortholog of Neurofibromin 1 (dNf1), precipitates associative learning deficits. However, the affected circuitry in the adult CNS remained unclear and the compromised mechanisms debatable. Although the main evolutionarily conserved function attributed to Nf1 is to inactivate Ras, decreased cAMP signalling upon its loss has been thought to underlie impaired learning. Read More

Taste-induced facial responses in black-handed spider monkeys (Ateles geoffroyi).

Behav Processes 2021 May 7:104417. Epub 2021 May 7.

IFM Biology, Linköping University, SE-581 83, Linköping, Sweden. Electronic address:

Taste-induced facial expressions are thought to reflect the hedonic valence of an animal's gustatory experience. We therefore assessed taste-induced facial responses in six black-handed spider monkeys (Ateles geoffroyi) to water, sucrose, caffeine, citric acid and aspartame, representing the taste qualities sweet, bitter, and sour, respectively. We decided not to include salty-tasting substances as the concentrations of such tastants found in the fruits consumed by spider monkeys are below their taste preference threshold. Read More

Long-term continuous cropping affects ecoenzymatic stoichiometry of microbial nutrient acquisition: A case study from a Chinese Mollisol.

J Sci Food Agric 2021 May 10. Epub 2021 May 10.

Key Laboratory of Mollisols Agroecology, Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, Harbin, 150081.

Background: Soil- and plant-produced extracellular enzymes drive nutrient cycling in soils and are thought to be regulated supply and demand for carbon (C) and nutrients within the soil. Thus, agriculture management decisions that alter the balance of plant and supplemental nutrients should directly alter extracellular enzyme activities (EEAs), and EEA stoichiometry in predictable ways. We used a 12-year experiment varying three major continuous grain crops (wheat, soybean, and maize) each crossed with mineral fertilizer (WCF, SCF, and MCF, respectively) or not fertilized (WC, SC, and MC, respectively, as controls).

Toll9 from functions as a pattern recognition receptor that shares features with Toll-like receptor 4 from mammals.

Proc Natl Acad Sci U S A 2021 May;118(19)

Guangdong Laboratory for Lingnan Modern Agriculture, Laboratory of Insect Molecular Biology and Biotechnology, Guangdong Provincial Key Laboratory of Agro-Animal Genomics and Molecular Breeding, College of Animal Science, South China Agricultural University, 510642 Guangzhou, China;

Toll/Toll-like receptors (TLRs) are key regulators of the innate immune system in both invertebrates and vertebrates. However, while mammalian TLRs directly recognize pathogen-associated molecular patterns, the insect Toll pathway is thought to be primarily activated by binding Spätzle cytokines that are processed from inactive precursors in response to microbial infection. Phylogenetic and structural data generated in this study supported earlier results showing that Toll9 members differ from other insect Tolls by clustering with the mammalian TLR4 group, which recognizes lipopolysaccharide (LPS) through interaction with myeloid differentiation-2 (MD-2)-like proteins.

Moral status of the fetus and the permissibility of abortion: a contractarian response to Thomson's violinist thought experiment.

J Med Ethics 2021 May 7. Epub 2021 May 7.

Australian Graduate School of Policing and Security, Charles Sturt University, Barton, Australian Capital Territory, Australia

Judith Jarvis Thomson famously argued that abortion is permissible even if we accept that a fetus qualifies as a person and possesses a right to life. The current paper presents two arguments that undermine Thomson's position. First, the paper sketches a contractarian argument that explores Thomson's violinist thought experiment from behind a veil of ignorance, which suggests that if we had an equal likelihood of being an unwanted fetus and a pregnant woman, it would be rational for us to oppose abortion.

Energy and corticosteroid mobilization following an induced stress response in an elasmobranch fish, the North Pacific spiny dogfish (Squalus acanthias suckleyi).

Gen Comp Endocrinol 2021 May 4:113799. Epub 2021 May 4.

Department of Biological Sciences, 50 Sifton Road, University of Manitoba, Winnipeg R3T 2N2, Manitoba, Canada; Bamfield Marine Sciences Centre, 100 Pachena Road, Bamfield R3T 0A8, British Columbia, Canada.

The dominant corticosteroid in elasmobranchs, 1α-hydroxycorticosterone (1α-OHB), has a described role in mineral regulation but a presumptive role in energy balance. Energy demand in vertebrates following exposure to a stressor typically involves an immediate but transient release of glucocorticoids as a means of mobilizing available energy stores, usually in the form of glucose. Although a glucocorticoid role for 1α-OHB would be expected, direct glucocorticoid function of this steroid has yet to be reported in any elasmobranch. Read More

The debatable presence of PIWI-interacting RNAs in invasive breast cancer.

Cancer Med 2021 May 7. Epub 2021 May 7.

School of Medicine, Institute of Clinical Medicine, Pathology and Forensic Medicine, and Translational Cancer Research Area, University of Eastern Finland, Kuopio, Finland.

Numerous factors influence breast cancer (BC) prognosis, thus complicating the prediction of outcome. By identifying biomarkers that would distinguish the cases with poorer response to therapy already at the time of diagnosis, the rate of survival could be improved. Lately, Piwi-interacting RNAs (piRNAs) have been introduced as potential cancer biomarkers, however, due to the recently raised challenges in piRNA annotations, further evaluation of piRNAs' involvement in cancer is required.

Changes in Plasma Renin Activity after Renal Artery Sympathetic Denervation.

J Am Coll Cardiol 2021 Apr 22. Epub 2021 Apr 22.

SUNY Downstate College of Medicine, Brooklyn, NY, USA.

Background: The renin-angiotensin-aldosterone system plays a key role in blood pressure (BP) regulation and is the target of several anti-hypertensive medications. Renal denervation (RDN) is thought to interrupt the sympathetic-mediated neurohormonal pathway as part of its mechanism of action to reduce BP.

Objectives: To evaluate plasma renin activity (PRA) and aldosterone before and after RDN and to assess whether these baseline neuroendocrine markers predict response to RDN. Read More

Recent Advances in Effector-Triggered Immunity in Plants: New Pieces in the Puzzle Create a Different Paradigm.

Int J Mol Sci 2021 Apr 29;22(9). Epub 2021 Apr 29.

Division of Applied Life Science (BK21 Four Program), Plant Molecular Biology and Biotechnology Research Center, Gyeongsang National University, 501 Jinju-daero, Jinju 52828, Korea.

Plants rely on multiple immune systems to protect themselves from pathogens. When pattern-triggered immunity (PTI)-the first layer of the immune response-is no longer effective as a result of pathogenic effectors, effector-triggered immunity (ETI) often provides resistance. In ETI, host plants directly or indirectly perceive pathogen effectors via resistance proteins and launch a more robust and rapid defense response. Read More
