In this study, we explore the structural and dynamic adaptations of the Tryptophan synthase α-subunit in a ligand bound state in psychrophilic, mesophilic and hyperthermophilic organisms at different temperatures by MD simulations. We quantify the global and local fluctuations in the 40 ns time scale by analyzing the root mean square deviation/fluctuations. The distinct behavior of the active site and loop 6 is observed with the elevation of temperature. Protein stability relies more on electrostatic interactions, and these interactions might be responsible for the stability of varying temperature evolved proteins...

Behavioral activation is an effective treatment for depression, based on targeting deprivation of positive rewards. It becomes more and more evident that many forms of mental disorders and psychological suffering involve reduction of goal-driven and pleasant activities. This reduction leaves negative mental states free to take the center of consciousness, without being counterbalanced by positive feelings, memories, and experiences of agency, self-efficacy, competence, relaxation, energy, and satisfaction. Reduced activity can be found in disorders ranging from chronic pain to personality disorders and schizophrenia...

INTRODUCTION: Research examining the implementation and effectiveness of integrated behavioral health (BH) care in family medicine/primary care is growing. However, research identifying ways to consistently use integrated BH in busy family medicine/primary care settings with underserved populations is limited. This study describes 1 family medicine clinic's transformation into a fully integrated BH care clinic through the development of an Integrated Care Clinic (ICC) and enhanced clinical pathways to promote regular use of behavioral health clinicians (BHCs)...

OBJECTIVE: We examined whether brief behavioral health visits reduced suicidal and self-harm ideation among primary care patients and compared the effectiveness of interventions that targeted ideation directly (i.e., safety planning) with those that targeted ideation indirectly through management of underlying mental illness (e.g., behavioral activation). METHOD: We examined first- and last-visit data from 31 primary care patients with suicidal or self-harm ideation seen by behavioral health consultants...

In a conformational nonequilibrium steady state (cNESS), enzyme turnover is modulated by the underlying conformational dynamics. On the basis of a discrete kinetic network model, we use an integrated probability flux balance method to derive the cNESS turnover rate for a conformation-modulated enzymatic reaction. The traditional Michaelis-Menten (MM) rate equation is extended to a generalized form, which includes non-MM corrections induced by conformational population currents within combined cyclic kinetic loops...

Multicomponent porous colloidal spheres are of interest because they not only show a combination of the properties associated with all different components, but also usually present synergy effect. However, combination of different components in a single porous sphere is still greatly challenged due to different precipitation behaviors of each component. In this work, we have developed a general synthetic route to prepare several categories of porous monodisperse RE-based colloidal spheres with customizable elemental compositions and uniform element distribution...

Microglia, resident immune cells of the CNS are sensitive to various perturbations of the environment, such as stress exposure, and may be involved in translating these changes to behavior. Among the pathways mediating stress-related neuronal cues to microglia, the fractalkine-fractalkine receptor (CX3CR1) signaling plays a crucial role. Using mice, in which the CX3CR1 gene was deleted, we explored hormonal and behavioral responses to acute and chronic stress along with changes in hypothalamic microglia. CX3CR1(-/-) animals display active escape in forced swim- and tail suspension tests, exaggerated neuronal activation in the hypothalamic paraventricular nucleus and increased corticosterone release in response to restraint...

A myriad of shapes are found in biological tissues, often naturally evolved to fulfill a particular function. In the field of tissue engineering, substrate geometry influences cell behavior and tissue formation in-vitro, yet little is known how this translates to an in-vivo scenario. Here we investigate scaffold curvature-induced tissue growth, without additional growth factors or cells, in an ovine animal model. We show that soft tissue formation follows a curvature-driven tissue growth model. The highly organized endogenous soft matrix, potentially under mechanical strain, leads to a non-standard form of biomineralization, whereby the pre-existing organic matrix is mineralized without collagen remodeling and without an intermediate cartilage ossification phase...

The Drosophila antenna contains receptor neurons for mechanical, olfactory, thermal, and humidity stimuli. Neurons expressing the ionotropic receptor IR40a have been implicated in the selection of an appropriate humidity range [1, 2], but although previous work indicates that insect hygroreceptors may be made up by a "triad" of neurons (with a dry-, a cold-, and a humid-air-responding cell [3]), IR40a expression included only cold- and dry-air cells. Here, we report the identification of the humid-responding neuron that completes the hygrosensory triad in the Drosophila antenna...

After discovering a small drop of food, hungry flies exhibit a peculiar behavior in which they repeatedly stray from, but then return to, the newly discovered resource. To study this behavior in more detail, we tracked hungry Drosophila as they explored a large arena, focusing on the question of how flies remain near the food. To determine whether flies use external stimuli, we individually eliminated visual, olfactory, and pheromonal cues. In all cases, flies still exhibited a centralized search behavior, suggesting that none of these cues are absolutely required for navigation back to the food...

How do brains shape social networks, and how do social ties shape the brain? Social networks are complex webs by which ideas spread among people. Brains comprise webs by which information is processed and transmitted among neural units. While brain activity and structure offer biological mechanisms for human behaviors, social networks offer external inducers or modulators of those behaviors. Together, these two axes represent fundamental contributors to human experience. Integrating foundational knowledge from social and developmental psychology and sociology on how individuals function within dyads, groups, and societies with recent advances in network neuroscience can offer new insights into both domains...

Children and adolescents with Neurofibromatosis type 1 (NF1) are at increased risk for wide-ranging behavioral, developmental, and cognitive impairments and decreased quality of life. To date, no psychosocial screening tool has been developed to quickly assess the symptoms that 1) can be addressed during routine medical appointments in children with NF1, 2) can produce interpretable and actionable results, 3) can be integrated into medical care, and 4) can quickly identify patients at risk in order to better address that the provision of appropriate care are available...

In social interactions, we often need to quickly infer why other people do what they do. More often than not, we infer that behavior is a result of personality rather than circumstances. It is unclear how the tendency itself may contribute to psychopathology and interpersonal dysfunction. Borderline personality disorder (BPD) is characterized by severe interpersonal dysfunction. Here, we investigated if this dysfunction is related to the tendency to over-attribute behaviors to personality traits. Healthy controls and patients with BPD judged positive and negative behaviors presented within a situational constraint during functional magnetic resonance imaging...

OBJECTIVE: When integrated behavioral health clinicians (IBHCs) and residents co-manage patients, residents may learn new approaches. We aimed to understand the effect of co-management on residents' behavioral health (BH) management learning. METHODS: Residents completed a web-based survey enquiring: whether co-management included a shared visit and/or face-to-face meeting with an IBHC, whether residents received feedback from the IBHC, and what they learned. Qualitative responses were coded thematically using a constant comparative method...

Relapse following treatment for substance use disorders is highly prevalent, and craving has been shown to be a primary predictor of relapse. Mindfulness-Based Relapse Prevention (MBRP) is a psychosocial aftercare program integrating mindfulness and cognitive-behavioral approaches, aimed at reducing the risk and severity of relapse. Results from a recent randomized clinical trial demonstrate enhanced remission resilience for MBRP participants versus both cognitive-behavioral and treatment-as-usual controls...

This study examined factors associated with mental health services (MHS) use by individuals with mental disorders within a developmental perspective of adulthood. Bivariate and multivariate analyses were conducted separately for each developmental stage on independent variables using the Andersen's behavioral health service model. For 18-29-year-old emerging adults (n = 141), autonomy, daily life/relations, Internet searching, alcohol dependence, cognitive impulsiveness, number of stressful events, and self-harm were associated with MHS use...

FtsZ (filamenting temperature-sensitive mutant Z) is a key protein in bacteria cell division. The wild-type Escherichia coli FtsZ sequence (FtsZwt) contains three tyrosine (Tyr, Y) and sixteen methionine (Met, M) residues. The Tyr at position 222 is a key residue for FtsZ polymerization. Mutation of this residue to tryptophan (Trp, W; mutant Y222W) inhibits GTPase activity resulting in an extended time in the polymerized state compared to FtsZwt. Protein oxidation has been highlighted as a determinant process for bacteria resistance and consequently oxidation of FtsZwt and the Y222W mutant, by peroxyl radicals (ROO•) generated from AAPH (2,2'-azobis(2-methylpropionamidine) dihydrochloride) was studied...

Breast carcinomas can be stratified into different entities based on clinical behavior, histological features and/or by biological properties. A classification of breast cancer should be based on underlying biology, which we know must be determined by the somatic genomic landscape of mutations. Moreover, as the latest generations of anti-cancer agents are founded on biological mechanisms, a detailed molecular stratification is a requirement for appropriate clinical management. Such stratification, based on genomic drivers, will be important for selecting patients for clinical trials...

Mitochondrial respiratory chain (RC) disease is a heterogeneous and highly morbid group of energy deficiency disorders for which no proven effective therapies exist. Robust vertebrate animal models of primary RC dysfunction are needed to explore the effects of variation in RC disease subtypes, tissue-specific manifestations, and major pathogenic factors contributing to each disorder, as well as their pre-clinical response to therapeutic candidates. We have developed a series of zebrafish (Danio rerio) models that inhibit, to variable degrees, distinct aspects of RC function, and enable quantification of animal development, survival, behaviors, and organ-level treatment effects on function as well as mitochondrial biochemistry and physiology...

Single nanowire lasers based on bottom-up III-V materials have been shown to exhibit room-temperature near-infrared lasing, making them highly promising for use as nanoscale, silicon-integrable and coherent light sources. While lasing behavior is reproducible, small variations in growth conditions across a substrate arising from the use of bottom-up growth techniques can introduce inter-wire disorder, either through geometric or material inhomogeneity. Nanolasers critically depend on both high material quality and tight dimensional tolerances, and as such, lasing threshold is both sensitive to, and a sensitive probe of such inhomogeneity...
