Basophil Activation Test Differentiates Between Patients with Alpha-Gal Syndrome and Asymptomatic Alpha-Gal Sensitization.

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.

Differences in the synchronization of alpha oscillations between anterior and posterior brain regions.

Alpha oscillations generated in the human brain have long been investigated in neuroscience. Synchronized oscillatory activities of numerous neural oscillators are thought to underlie alpha oscillations. The amplitude of alpha oscillations reflects the degree of synchronization, which is often modulated through alpha activation and inactivation, for example, in event-related synchronization and desynchronization. The range of synchronization can be estimated using the similarity between neighboring alpha os...

Is knowledge "half the battle"? The role of depression literacy in help-seeking among a non-clinical sample of adults with currently untreated mental health problems.

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.

(-)-Stepholidine reduces cue-induced reinstatement of cocaine seeking and cocaine self-administration in rats.

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).

Dynamics of spontaneous alpha activity correlate with language ability in young children.

Early childhood is a period of tremendous growth in both language ability and brain maturation. To understand the dynamic interplay between neural activity and spoken language development, we used resting-state EEG recordings to explore the relation between alpha oscillations (7-10 Hz) and oral language ability in 4- to 6-year-old children with typical development (N = 41). Three properties of alpha oscillations were investigated: a) alpha power using spectral analysis, b) flexibility of the alpha fre...

The Art (and Artifice) of Seeking Feedback: Clerkship Students' Approaches in Asking for Feedback.

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.

Reducing threat responses to help-seeking information: Influences of self-affirmations and reassuring information.

This research was an examination of the effects of two types of self-affirmation interventions in reducing threat responses associated with receiving help-seeking information. Help-seeking information can be threatening to one's positive self-perceptions and people may avoid seeking such information to protect themselves. There is evidence that reflecting on personal values (values affirmation) may bolster self-integrity and mitigate this avoidance, and it is possible that reflecting on safe, close social r...

Detection of alpha radionuclides in air from patients during Ra-223 alpha radionuclide therapy.

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 ...

Trends and patterns in UK treatment seeking gamblers: 2000-2015.

Gambling is an activity that for some can become disordered, with severe negative consequences. Existing literature does little to inform us regarding changing gambling habits of treatment seeking gamblers; the current study sought to measure trends and patterns in UK treatment seeking gambler behaviour and demographics over a 15-year period.

Longterm Homecare Augmentation Program in Alpha-1-Antitrypsin Deficient Patients.

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.

Functioning mediates help-seeking for mental problems in the general population.

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.

Help-seeking experiences of older adults with a diagnosis of moderate depression.

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...

PTSD Symptom Severity, but Not Trauma Type, Predicts Mental Health Help-seeking in the Military.

Although veterans with posttraumatic stress disorder (PTSD) have been reported to have high rates of inadequate treatment, to our knowledge this is the first study to evaluate associations between each individual PTSD symptom and treatment-seeking, and the first PTSD help-seeking study to evaluate variables across all-rather than specific-types of trauma.

Ubiquitin specific protease-13 independently regulates parkin ubiquitination and alpha-synuclein clearance in alpha-synucleinopathies.

Ubiquitin specific proteases (USPs) are de-ubiquitinases that control protein ubiquitination cycle. The role of de-ubiquitinases is poorly understood in neurodegenerative diseases. We found that USP13 is overexpressed in post-mortem Parkinson's disease (PD) brain. We investigated whether changes in USP13 levels can affect two molecules, parkin and alpha-synuclein, that are implicated in PD pathogenesis. Parkin is an E3 ubiquitin ligase that is regulated by ubiquitination and targets certain proteins for deg...

Characterizing the health and information-seeking behaviours of Ontarians in response to the Zika virus outbreak.

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.

Care-seeking practices for sick neonates: Findings from cross-sectional survey in 14 rural sub-districts of Bangladesh.

Neonatal deaths account for 45% of all under-five deaths globally and 60% in Bangladesh. This study aimed to investigate the most common symptoms and complications in neonates, care-seeking practices of the mothers for their sick neonates, and factors associated with the care-seeking practices.

Sex-Based Differences in Symptom Perception and Care-Seeking Behavior in Acute Stroke.

Lack of early stroke recognition and delays in seeking emergency care by persons experiencing a stroke severely limit acute treatment options. Sparse and sometimes conflicting evidence suggests sex differences in care-seeking behaviors in stroke, stroke knowledge, perceptions of stroke symptoms, and the importance of physical location at the time of stroke and of having a witnessed stroke.

Gamblers seeking online help are active help-seekers: Time to support autonomy and competence.

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...

The frequency of alpha oscillations: Task-dependent modulation and its functional significance.

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 ...

Stress as a context: Stress causes relapse of inhibited food seeking if it has been associated with prior food seeking.

Three experiments with rats explored the hypothesis that inhibited food-seeking can be reinstated by stress if stress has been part of the context of earlier food-seeking. In all experiments, rats first learned to lever press for sucrose pellets and then had the response inhibited through extinction (where responding no longer yielded sucrose pellets). In a final test, inhibited responding was tested after exposure to a stressor or not. Previous research indicates that stress during testing does not normall...

Candidate genes for novelty-seeking: a meta-analysis of association studies of DRD4 exon III and COMT Val158Met.

Two widely studied genetic polymorphisms in the dopaminergic system [DRD4 exon III variable number of tandem repeat (VNTR) and COMT Val158Met] have been reported to be associated with novelty-seeking, but the results have been highly inconsistent. Therefore, a meta-analysis of the associations between these two polymorphisms and novelty-seeking was conducted.

Novel Alpha-Synuclein Oligomers Formed with the Aminochrome-Glutathione Conjugate Are Not Neurotoxic.

Aminochrome induces neurotoxic alpha-synuclein oligomer formation relevant to the etiology of Parkinson's disease. Oxidative stress produces aminochrome from dopamine, but conjugation with glutathione catalyzed by glutathione transferase M2-2 significantly decreases aminochrome-induced toxicity and alpha-synuclein oligomer formation. Notably, in the presence of the aminochrome-glutathione conjugate, previously unknown species of alpha-synuclein oligomers are formed. These aminochrome-glutathione oligomers o...

The Interactive Effects of Parental Knowledge with Impulsivity and Sensation Seeking in Adolescent Substance Use.

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...

Attitudes Towards Seeking Psychological Help: An Integrative Model Based on Contact, Essentialist Beliefs About Mental Illness, and Stigma.

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 ...

Investigation of the interaction between bta-miR-222 and the estrogen receptor alpha gene in the bovine ovarium.

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 ...
