The alpha-gal syndrome is characterized by the presence of sIgE antibodies to alpha-gal and delayed type I allergic reaction to the carbohydrate galactose-alpha-1,3-galactose (alpha-gal) after consumption of mammalian (red) meat products and drugs of a mammalian origin. Diagnostics currently rely on patient history, skin tests, determination of sIgE antibodies, oral food or drug challenges.
Novelty seeking (the tendency to explore things novel and unfamiliar) has been extensively researched in the clinical and health domains, but its effects on creative performance are largely unknown. We examined whether creativity-related personality traits (openness to experience and extraversion) associate with novelty seeking, and whether novelty seeking is linked to, and facilitates, creativity.
The concept of mental health literacy suggests that higher literacy increases the likelihood of seeking treatment. However, previous studies mostly use vignettes, and do not investigate actual help-seeking behaviour.
Dopamine receptors are implicated in cocaine reward and seeking. We hypothesize that (-)-stepholidine, a dopamine D1/D2/D3 multi-receptor agent, would be effective in reducing cocaine reward and seeking in an animal model. We investigated the effects of (-)-stepholidine in cue-induced reinstatement of cocaine seeking and cocaine self-administration (reward).
As attention has shifted to learners as significant partners in feedback interactions, it is important to explore what feedback-seeking behaviors medical students use and how the faculty-student relationship affects feedback-seeking behaviors.
Ra-223 has recently been introduced to alpha radionuclide therapy. According to the decay scheme of Ra-223, an inert gas, Rn-219 is released from patients during alpha radionuclide therapy and its daughter radionuclides may accumulate around the patient. However, the concentration of these radon daughters during alpha radionuclide therapy was not obvious. Here, we first detected the radon daughters of Rn-219 around patients during alpha radionuclide therapy. While the Ra-223-administered patients were in a ...
Absent or delayed help-seeking is considered to aggravate the immense personal and societal burden caused by mental disorders. Therefore, we cross-sectionally examined rates and clinical and sociodemographic moderators of early help-seeking for current clinician-assessed non-psychotic mental problems/disorders in the community.
Augmentation with human alpha-1 proteinase inhibitor is the only specific treatment for Alpha-1-Antitrypsin Deficiency (AATD), a rare genetic disease with symptoms of progressive COPD.
Depression is the most prevalent mental illness among older adults. However, help-seeking by older adults is frequently delayed, resulting in longer duration of untreated symptoms, poorer health outcomes, and consequent higher healthcare use. Early help-seeking and access to appropriate support benefits individuals, while providing better outcomes from health systems constrained by limited resources. The aim of this study, which is abstracted from a larger study, was to identify the factors that inhibited a...
The purpose of this study is to describe the impact of the 2016 Zika virus (ZIKV) outbreak on the health-seeking and information-seeking behaviours of Ontarians.
Research investigating rates of help-seeking for problem gambling has traditionally focused on the uptake of face-to-face gambling services alone, despite the World Health Organisation defining help-seeking as any action or activity undertaken to improve or resolve emotional, psychological or behavioural problems. The primary aim of this study is to examine the full range of help-seeking options utilised by gamblers, and to determine whether administering a comprehensive list of help options yields higher h...
Power (amplitude) and frequency are two important characteristics of EEG alpha oscillations (8-12 Hz). There is an extensive literature showing that alpha power can be modulated in a goal-oriented manner to either enhance or suppress sensory information processing. Only a few studies to date have examined the task-dependent modulation of alpha frequency. Instead, alpha frequency is often viewed as a trait variable, and used to characterize individual differences in cognitive functioning. We performed two ...
This study examined whether interactions of parental knowledge of adolescent's whereabouts with impulsivity and sensation seeking in the prediction of adolescent substance use supported the diathesis-stress or differential susceptibility model in 230 15-year old adolescents (53% girls). Interactions between impulsivity and parental knowledge supported the diathesis-stress model with high impulsivity as a vulnerability factor: when impulsivity was higher, low levels of parental knowledge were associated with...
Based on intergroup contact theory, a proposed comprehensive model of attitudes towards seeking professional psychological help was tested, including both potential barriers to mental health help-seeking (i.e., public stigma and self-stigma of seeking help, prejudicial and essentialist beliefs about mental illness, intergroup anxiety) and potential facilitators (i.e., direct and extended contact with persons with mental illness). Relevant measures were completed by 119 community-dwelling participants. Path ...
This study sought to replicate and extend research on social facilitators of college student's help seeking for psychological problems.
The fruit fly can evaluate its energy state and decide whether to pursue food-related cues. Here, we reveal that the mushroom body (MB) integrates hunger and satiety signals to control food-seeking behavior. We have discovered five pathways in the MB essential for hungry flies to locate and approach food. Blocking the MB-intrinsic Kenyon cells (KCs) and the MB output neurons (MBONs) in these pathways impairs food-seeking behavior. Starvation bi-directionally modulates MBON responses to a food odor, suggesti...
The aim of the present study was to investigate the posttranscriptional regulation of bta-miR-222 and the estrogen receptor (ER)-alpha gene in cows. The preovulatory follicles (POFs) were detected and ER-alpha levels in the corpus luteum (CL) were measured via immunofluorescent method. Afterwards, an ELISA test was performed to detect estradiol- and progesterone-active follicles, and the expression levels of ER-alpha, progesterone receptor (PR), and bta-miR-222 were measured via qRT-PCR. Finally, a western ...
Type 2 diabetes mellitus (T2DM) is closely related to islet alpha cell mass and viability. Several types of RFamide-related peptides (RFRPs) are involved in regulating proliferation and function of islet cells. However, current understanding of the role of RFamide-related peptide-3 (RFRP-3) in pancreatic alpha cells is limited. Therefore, we investigated the expression of the RFRP-3 receptor, G protein-coupled receptor 147 (GPR147), in mouse islets and alpha TC1 clone 6 cells, and evaluated the function of ...
Delays in seeking timely appropriate care contributes to a large number of deaths from diarrhea in children. This study aimed to identify determinants of delays in seeking timely treatment by mothers/caregivers of under-five children with diarrheal diseases.
To date it is unclear whether the selectivity of new alpha-blockers to alpha-adrenergic receptor subtypes translates into more clinical benefits and less adverse effects in clinical practice. We performed a systematic review of the two new Abs silodosin and naftopidil. With the availability of numerous alpha-blockers to treat lower urinary tract symptoms secondary to benign prostatic hyperplasia, the findings of this review will be highly relevant to the field of urology.
Oscillatory brain activity in the theta, alpha, and gamma frequency ranges has been associated with working memory (WM). In addition to alpha and theta activity associated with WM retention, and gamma band activity with item encoding, activity in the alpha band is related to the deployment of attention resources and information. The present study sought to specify distinct roles of neuromagnetic 4-7 Hz theta, 9-13 Hz alpha, and 50-70 Hz gamma power modulation and communication in fronto-parietal netwo...
To examine predictors of information seeking behavior among individuals diagnosed with cancer versus those without.
Alpha-synuclein can form beta-sheet filaments, the accumulation of which plays a key role in the development of Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. It has previously been shown that alpha-synuclein is a substrate for the HECT domain-containing ubiquitin ligase Nedd4, and is subject to ubiquitin-mediated endosomal degradation. We show here that alpha-synuclein filaments are much better substrates for ubiquitination in vitro than monomeric alpha-synuclein, and that this...
The influence of flanking structures (alpha helices and beta strands in the primary sequence) on amino acid content of the elements of secondary structure has been analyzed in seven sets of nonhomologous proteins. Elevated usage of beta structural amino acid residues and pentapeptides in beta strands between two alpha helices can be explained by the stabilization of secondary structure of those beta strands by natural selection. High usage of alpha helical amino acids and pentapeptides in beta strands situa...
Selective attention can enhance Working Memory (WM) performance by selecting relevant information, while preventing distracting items from encoding or from further maintenance. Alpha oscillatory modulations are a correlate of visuospatial attention. Specifically, an enhancement of alpha power is observed in the ipsilateral posterior cortex to the locus of attention, along with a suppression in the contralateral hemisphere. An influential model proposes that the alpha enhancement is functionally related to t...
