Airway hyperreactivity in asthma is mediated by airway nerves, including sensory nerves in airway epithelium and parasympathetic nerves innervating airway smooth muscle. Isolating the function of these two nerve populations in vivo, to distinguish how each is affected by inflammatory processes and contributes to hyperreactivity in asthma, has been challenging. In this study, we used optogenetic acti-vation of airway nerves in vivo to study parasympathetic contributions to airway hyperreactivity in two mouse models of asthma: 1) acute challenge with house dust mite antigen, and 2) chronic airway hy-pereosinophilia due to genetic IL-5 overexpression in airways.

Sleep disruption is proposed to contribute to these pathological processes and is a common early feature among neurodegenerative disorders. Synucleinopathies are a subclass of neurodegenerative conditions defined by the presence of α-synuclein aggregates, which may not only enhance cell death, but also contribute to disease progression by seeding the formation of additional aggregates in neighboring cells.

In this paper, we introduce and outline the utility of a new intraindividual variability construct, affective sensitivity to air pollution (ASAP)-defined as the extent to which an individual's affective states fluctuate in accordance with daily changes in air quality. As such, ASAP pushes beyond examination of differences in individuals' exposures to air pollution to examination of differences in individuals' sensitivities to air pollution.

The vast majority of this large literature has been conducted in Western convenience and clinical samples. We computed interpersonal problem structural summary parameters for a range of personality and psychopathology variables in two Chinese offender samples ( = 424 and = 555) and one undergraduate sample ( = 511) to test how well findings from Western samples generalize to Chinese undergraduates and offenders.

Asthma susceptibility is influenced by environmental, genetic, and epigenetic factors. DNA methylation is one form of epigenetic modification that regulates gene expression and is both inherited and modified by environmental exposures throughout life. Prenatal development is a particularly vulnerable time period during which exposure to maternal asthma increases asthma risk in offspring.

Though we agree that personality trait models are powerful descriptive tools, we highlight that they lack definitional or explanatory power, and that is why they have not been able to define or distinguish what PDs are (Hopwood, 2018; Mõttus et al.

However, considering the rich history of narcissism research accompanied by its diverging conceptualizations, little is known about age and gender differences across various narcissism measures. The present study investigated age and gender differences and their interactions across eight widely used narcissism instruments (i.

This research aims to understand how satisfaction/frustration of interpersonal motives (operationalized as interpersonal complementarity) impacts affect, using Contemporary Integrative Interpersonal Theory as a guiding framework. Participants ( = 227) rated actor and partner agency and communion in interpersonal interactions in 6 prompted surveys per day for 21 days.

We aimed to validate the Arabic version of the original Pathological Narcissistic Inventory (PNI) and its brief form (B-PNI) in a community sample of Lebanese adults.
Methods: The English language PNI items were translated into Arabic following a rigorous translation, back-translation, and linguistic evaluation.

The current study applied the interpersonal construct validation approach to self-report data from 856 undergraduate students to formally examine the interpersonal content, similarities, and differences in the subscales of four measures of STPP within and across two interpersonal circumplex surfaces using a bootstrapping methodology for computing confidence intervals around circumplex structural summary method parameters. Results suggested that negative-like expressions of STPP are prototypically and distinctively interpersonal constructs associated with cold and socially avoidant interpersonal problems and hypersensitivity to others' warmth and affection.

From a clinical perspective, it is challenging to help individuals with personality disorders because treatment ruptures, discontinuation, reversals, and failures are relatively common. An additional clinical challenge is that the model used to diagnose personality disorders is demonstrably incorrect.

Child abuse was positively associated with engaging in all forms of interpersonal violence for both genders. For women, pathological narcissism moderated this association such that higher levels of pathological narcissism reduced the association between child abuse and engaging in stalking, sexual harassment, sexual aggression.

Asthma is a heterogeneous inflammatory airway disease that develops in response to a combination of genetic predisposition and environmental exposures. Patients with asthma are grouped into phenotypes with shared clinical features and biomarker profiles to help tailor specific therapies. However, factors driving development of specific phenotypes are poorly understood.

These neurotransmitter-specific subpopulations did not form intraganglionic interneurons, but rather, extended outside the ganglia, into the airways, to distant innervation targets. Our experiments demonstrate the utility of multicolor labeling to characterize airway innervation, allowing us to confirm the extensive heterogeneity of postganglionic parasympathetic neurons.

As the empirical literature on the clinical utility of the AMPD grows, there is a need to examine changes in diagnostic profiles and personality expression in treatment over time. Assessing these changes in individuals diagnosed with borderline personality disorder (BPD) is complicated by the tendency for patients to cycle through multiple therapists over the course of treatment leaving the potential for muddled diagnostic clarity and disjointed case conceptualizations.

Participants consisted of 290 undergraduate students from four universities in three different cities in Iran, recruited by available sampling, Instruments, including, Pathological Narcissism Inventory (PNI) and the NEO Five-Factor Inventory (NEO-FFI) were also completed for the participants. Hierarchical regression analysis showed that narcissistic grandiosity was positively associated with extraversion and openness, while narcissistic vulnerability and overall pathological narcissism were positively associated with neuroticism and negatively related to agreeableness and openness (only for narcissistic vulnerability).
