Dermestidae and Tenebrionidae are well known inhabitants of bird's nests and poultry farms, under favourable conditions they can be very abundant under favourable conditions. At times, their larvae shift from a scavenging behaviour to a parasitic/predatory one, entering nestling's plumage and feeding on skin and feathers, and nally provoking skin damages and blood losses. These episodes mainly involve species of the genus Dermestes, but the tenebrionid Alphitobius diaperinus h also been reported to be responsible of similar cases...

Since the discovery of neural regions in the monkey brain that respond preferentially to multisensory stimuli presented in proximal space, researchers have been studying this specialised spatial representation in humans. It has been demonstrated that approaching auditory or visual stimuli modulate tactile processing, while they are within the peripersonal space (PPS). The aim of the current study is to investigate the additional effects of tactile expectation on the PPS-related multisensory interactions. Based on the output of a computational simulation, we expected that as tactile expectation increases rapidly during the course of the motion of the visual stimulus, the outcome RT curves would mask the multisensory contribution of PPS...

Sirtuin (SIRT1) inactivation underlies the pathogenesis of insulin resistance and hyperglycaemia-associated vascular complications, but its role in diabetic neuropathy (DN) has not been yet explored. We have evaluated hyperglycaemia-induced alteration of SIRT1 signalling and the effect of isoliquiritigenin (ILQ) on SIRT1-directed AMP kinase (AMPK) and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) signalling in peripheral nerves of streptozotocin (STZ) (55 mg/kg, ip)-induced diabetic rats and in high glucose (30 mM)-exposed neuro2a (N2A) cells...

OBJECTIVE: The true prevalence of hypoglycemia in insulin-treated patients with diabetes and its impact on patients, employers and healthcare providers is poorly appreciated owing to a paucity of real-world data. The global Hypoglycemia Assessment Tool (HAT) study addressed this issue, and here we report data from the Canadian cohort of patients. METHODS: This noninterventional, 6-month retrospective and 4-week prospective study enrolled patients aged ≥18 years receiving insulin treatment for >12 months from community endocrinology practices...

Two hydrogenated roll-in shortenings (A & B), one non-hydrogenated roll-in shortening and butter were used to prepare croissants. The impact of the laminated dough matrix on fat crystallization was then investigated using powder X-ray diffraction (XRD), pulsed nuclear magnetic resonance (p-NMR) and differential scanning calorimetry (DSC). The fat contained within a croissant matrix has never before been analyzed using these techniques. In each case, XRD revealed that the polymorphism of a roll-in fat will be different when baked within the dough matrix than when simply heated and cooled on its own...

Polysaccharides extracted from medicinal plants possess multiple functions. However, the inhibitory capacity of polysaccharides on the metastasis of breast cancer remains unclear. In the present study, we investigated the inhibitory activity of Aconitum coreanum polysaccharide (ACP1) and its sulphated derivative ACP1-s on migratory behaviour of human breast cancer cells MDA-MB-435s and evaluated the underlying molecular mechanism. The data from Transwell assay indicated that ACP1 and ACP1-s caused a significant inhibition of MDA-MB-435s cell migration in vitro...

Being able to predict when an event will occur (temporal predictability) can help us prepare and time our responses. We here sought to delineate the neural and behavioural corollaries of highly implicit, probabilistic temporal predictability in an auditory foreperiod paradigm. To this end, we measured electroencephalography (EEG) and response times in two independent experiments (total N = 46). Unbeknownst to participants, we induced a probabilistic variation of cue-target delays (i.e., foreperiods) in a pitch-discrimination task on a noise-embedded tone: The smaller the standard deviation of the underlying foreperiod distribution, the more predictable the time of target occurrence should be...

While previous attempts to train self-control in humans have frequently failed, we set out to train response inhibition using computer-game elements. We trained older adults with newly developed game-based inhibition training on a tablet for two months and compared them to an active and passive control group. Behavioural effects reflected in shorter stop signal response times were observed only in the inhibition-training group. This was accompanied by structural growth of right inferior frontal gyrus (rIFG) triangularis cortical thickness, a brain region that has been associated with response inhibition...

This study was undertaken to investigate whether, in rat interactive activities, recurring sequences of behavioural events might be identified and how and to what extent each component of the pair is involved. To this aim, the multivariate temporal-pattern (t-pattern) analysis was applied to the social interactions of 9 pairs of male Wistar rats tested in open field. Interactive activities were classified into intra- and inter-subjects. Quantitative evaluations showed that intra-subject behavioural elements represented 62...

The present study was designed to systematically assess the control experience routinely used in our laboratory as part of studies on predator odour stress. Specifically, we examined effects of the physical and social components of this control experience on measures of anxiety-like behaviour in adolescent rats. Adolescent animals are at increased susceptibility to environmental perturbations and have been used for such studies much less often. Male and female Long-Evans rats were subjected to physical stimulation (Exposed or Unexposed) and social stimulation (Single Housed or Pair Housed), resulting in four groups...

BACKGROUND: Half of all lifetime anxiety disorders emerge before age 12 years; however, access to evidence-based psychological therapies for affected children is poor. We aimed to compare the clinical outcomes and cost-effectiveness of two brief psychological treatments for children with anxiety referred to routine child mental health settings. We hypothesised that brief guided parent-delivered cognitive behavioural therapy (CBT) would be associated with better clinical outcomes than solution-focused brief therapy and would be cost-effective...

(14)N nuclear quadrupole resonance (NQR) lineshapes mostly contain information of low interest, although in nanocrystals they may display some unexpected behaviour. In this work, we present an ab initio computational study of the (14)N NQR lineshapes in urea nanocrystals as a function of the nanocrystal size and geometry, focusing on the surface induced broadening of the lineshapes. The lineshapes were obtained through a calculation of the electric field gradient for each nitrogen site in the nanocrystal separately, taking into account the individual crystal field by embedding the molecule of interest in a suitable lattice of point multipoles representing other urea molecules in the nanocrystal...

RATIONALE: Despite the publicised health risks associated with its usage, sunbed tanning remains popular in many Western countries. Previous research indicates that knowledge of the harmful effects does not necessarily lead to a reduction in sunbed use. OBJECTIVE: The aim of this study was to develop a more extensive social psychological understanding of sunbed use, in the United Kingdom, by exploring the social representations of sunbed tanning held by both those who use and who have never used sunbeds...

BACKGROUND: fetal Alcohol Spectrum Disorders is a term used to describe a range of physical, cognitive and behavioural deficits in the offspring of women who drank alcohol during pregnancy. A growing body of evidence suggests alcohol consumption in the presence of poor maternal nutrition may increase the risk of harm to the developing fetus. OBJECTIVE: to investigate relationships between maternal dietary patterns and alcohol consumption, and explore which factors influence women's decisions about what to eat and drink during pregnancy...

Insomnia is highly prevalent and is associated with a range of psychological, psychiatric, and medical conditions. Insomnia affects health by influencing cognitive, emotional and social functioning. Circadian and sleep homeostatic processes play an important role in insomnia development and its maintenance. Several efficacious treatments, both pharmacologic and non-pharmacologic, exist for the management of insomnia. Among non-pharmacologic treatments including stimulus control therapy, sleep restriction, relaxation, sleep hygiene and cognitive therapy have been shown to be efficacious...

Pseudomonas aeruginosa is a Gram-negative bacterium that is responsible for a wide range of infections in humans. Colonies employ quorum sensing (QS) to coordinate gene expression, including for virulence factors, swarming motility and complex social traits. The QS signalling system of P. aeruginosa is known to involve multiple control components, notably the las, rhl and pqs systems. In this paper, we examine the las system and, in particular, the repressive interaction of rsaL, an embedded small regulative protein, employing recent biochemical information to aid model construction...

This study describes the potential of solid lipid nanoparticles and nanostructured lipid carriers as nano-formulations to administer to the central nervous system poorly water soluble drugs. Different neuroactive drugs, i.e. dimethylfumarate, retinyl palmitate, progesterone and the endocannabinoid hydrolysis inhibitor URB597 have been studied. Lipid nanoparticles constituted of tristearin or tristearin in association with gliceryl monoolein were produced. The nanoencapsulation strategy allowed to obtain biocompatible and non-toxic vehicles, able to increase the solubility of the considered neuroactive drugs...

About 27% of cancer patients in Jordan are discovered in advanced stages; this resulted in poor prognosis and survival rates. One possible cause of late presentation is lack of awareness of warning signs and risk factors of cancer. The purpose of this study is to identify the level of awareness of cancer warning signs, risk factors, and barriers to seeking medical advice among the Jordanian public. A cross-sectional survey design was used. A convenience sample of 2292 participants from the Jordanian public was included in the study...

The amyloid-beta peptide (Aβ) plays a major role in the progression of Alzheimer's disease. Due to its high toxicity, the 42 amino acid long isoform Aβ42 has become of considerable interest. The Aβ42 monomer is prone to aggregation down to the nanomolar range which makes conventional structural methods such as NMR or X-ray crystallography infeasible. Conformational information, however, will be helpful to understand the different aggregation pathways reported in the literature and will allow to identify potential conditions that favour aggregation-incompetent conformations...
