The proposed water model can be trivially adopted by any package that supports standard nonpolarizable force fields and water models; its intended use is in long classical atomistic simulations where water polarization effects are expected to be important.Black individuals who smoke in the United States experience health disparities related to tobacco use (e.g., greater nicotine dependence, less success in quitting smoking) and interoceptive distress (e.g., somatic symptoms, anxiety). Individual difference factors that amplify interoceptive distress and contribute to poorer smoking behaviors and outcomes warrant further attention and investigation. Thus, the present study sought to explore the association between anxiety sensitivity and clinically-relevant smoking variables of perceived barriers for quitting, smoking inflexibility, and problems experienced during past quit attempts. Participants in the current study included 98 Black adult smokers (71.4% male; Mage = 44.08 years, SD = 11.44 years). selleckchem Results indicated greater levels of anxiety sensitivity were associated with greater levels of perceived barriers for quitting smoking (b = 0.10, SE = 0.08, p = 0.01), smoking inflexibility (b = 0.02, SE less then .001, p less then .001), and problems experienced during past smoking quit attempts (b = 0.17, SE = 0.07, p = 0.02). Clinical implications and future directions are further discussed as it relates to anxiety sensitivity and efforts to reduce or quit smoking for this health disparities population.
We aimed to clarify the pathophysiology of epilepsy involving seizures with apparently generalized onset, progressing to focal ictal rhythm through stereotactic EEG (SEEG) implantation, recording, stimulation and high-frequency oscillation (HFO) analysis.
We identified two patients with seizures with bilateral electrographic onset evolving to focal ictal rhythm, who underwent SEEG implantation. Patients had pre-surgical epilepsy work-up, including prolonged video scalp EEG, brain MRI, PET, ictal/interictal SPECT, MEG, and EEG-fMRI prior to SEEG implantation.
Both patients had childhood-onset seizures involving behavioural arrest and left versive head and eye deviation, evolving to bilateral tonic-clonic convulsions. Seizures were electrographically preceded by diffuse, bilateral 3-Hz activity resembling absence seizures. Both had suspected focal lesions based on neuroimaging, including 3T MRI and voxel-based post-processing in one patient. Electrode stimulation did not elicit any habitual electroclinical seizures. HFO analysis showed bilateral focal regions with high fast-ripple rates.
“Generalized-to-focal” seizures may occur due to a diffuse, bilateral epileptic network, however, both patients showed ictal evolution from a generalized pattern to a single dominant focus which may explain why the focal aspect of their seizures had a consistent clinical semiology. Patients such as these may have a unique form of generalized epilepsy, but focal/multifocal cerebral abnormalities are also a possibility.

Furthermore, its complex role in tumor behavior has recently been recognized. We previously demonstrated that phosphorylation of serine 363 in ARHGAP25 regulates hematopoietic stem cells and progenitor cells in mouse bone marrow. However, the significance of other potential phosphorylation sites of ARHGAP25 remained unknown. Now, we developed a novel, real-time bioluminescence resonance energy transfer (BRET) assay to monitor the GAP activity of ARHGAP25 in vitro. Using this approach, we revealed that phosphorylation of S363 and S488, but not that of S379-380, controls ARHGAP25's RACGAP activity. On the other hand, we found in granulocyte-differentiated human PLB-985 cells that superoxide production and actin depolymerization are regulated by residues S363 and S379-380. The present data demonstrate the value of our BRET-GAP assay and show that different phosphorylation patterns regulate ARHGAP25's GAP activity and its effect on superoxide production and phagocytosis.As the research and treatment of childhood cancer steadily progresses, so has the interest in children's needs, not only throughout such treatment but also following completion. Whilst there is increased literature focussing on the long-term psychosocial impact of treatment completion, little is currently known about how children and young people (CYP) experience the more immediate end of their cancer treatment. The current review seeks to examine CYP's experiences of the end of their cancer treatment. Sixteen studies were retrieved using a systematic search strategy across five databases, all of which used qualitative methodology. Thematic synthesis was chosen to analyse the data. Four overarching themes were generated, which encompassed 'the continuity of cancer', 'ambivalence of needs', 'making sense of the cancer experience' and 'sense of self following the ending'. The end of treatment is a time of complexity for CYP, yet it is currently largely overlooked. In order to scaffold these endings for CYP, increased emphasis and thought needs to be placed on the end of treatment and the support that is provided within it.
High turnover and recruitment challenges of nursing home employees and managers are an ongoing concern. This study's objective was to examine intent to quit among all staff and assess the roles of job characteristics and job satisfaction. Employees and managers within one nursing home chain working in direct patient care or nursing were compared.
Data came from the Work, Family, Health Network 18-month follow-up survey in 2012 (total = 1,000, managers = 101, employees = 899). A cumulative logit model controlling for demographics was estimated for intent to quit. Herzberg's Two-Factor Theory of Work Motivation guided the study.
Employees scored significantly lower on family-supportive supervisor behaviors (FSSBs), schedule control, and decision authority than managers. Employees and managers did not differ on job satisfaction, intent to quit, or job demands. Satisfied workers had an 83% decrease in the odds of reporting an intent to quit compared to workers who were neutral or disagreed (odds ratio [OR] = 0.17, p < .0001). Decision authority (OR = 3.49) and schedule control (OR = 5.18) were independently related to greater odds of reporting an intent to quit. In contrast, FSSBs (OR = 0.69), safety compliance (OR = 0.71), and the combination of high decision authority with high schedule control (OR = 0.72) were related to lower odds of reporting an intent to quit.
Among nursing home staff, lower intent to quit may be achieved through improving job satisfaction, the quality of supervision, safety culture, and job enrichment through more schedule control and decision-making power.

This includes the influences of Dr. Carol D. Saunders who coined the term "Conservation Psychology" in a 2003 special issue of Human Ecology to identify a more efficient way for those with psychological expertize to work together towards a common mission. In this introduction to Zoo Biology's special issue on Conservation Psychology, we discuss the articles that make up this collection and propose further avenues for research and consideration within the field.
Prevalence of mobile device addiction has increased over the years; both women and men have assimilated the mobile phone as a central component of their personal existence integrating it into their lifestyle or becoming so dependent on it that life without it has become unimaginable. Smartphones generate radio-frequency electromagnetic fields. While short-term exposure in adults was considered quite safe, effects of long-term exposure or exposure during pregnancy on fetuses or during breastfeeding on newborns are not well studied yet. The objective of the present study was to investigate the prevalence and usage characteristics of smartphones among a sample of pregnant women, and promote the correct and conscious use of the smartphone.
A cross-sectional study was conducted, with a questionnaire administered during childbirth classes and - after the questionnaire administration - an educational intervention focused on promoting the correct and conscious use of smartphones was carried out by psychologists aic, especially in relation to pregnancy. It seems necessary to sensitize future mothers on this topic. The promotion of a more conscious and controlled use of electronic devices can help reduce the radiation to which the unborn child may be exposed, but has a fundamental role even after birth, to ensure an adequate psychomotor and relational development of the child and do not affect, due to uncontrolled use of smartphones, the mother-child relationship.The scope of an umpolung approach to expand synthetic access to bifunctional γ-keto hydrazine intermediates via electrophilic amination of β-homoenolates derived from cyclopropanol precursors that took advantage of azodicarboxylates or azodicarboxamides as electron-deficient nitrogen sources was examined. This new synthetic procedure avails commercially available or readily accessible starting materials along with a ligand-free Cu(II) salt as an inexpensive catalyst. Using this operationally simple reaction, which proceeds under mild conditions (open-flask and ambient temperature) and is suitable for multigram scale, preparative applications were established with a range of aryl- and alkyl-substituted cyclopropanols and azodicarboxylate/azodicarboxamide substrates (26 examples, 74-95% yields). Further, the obtained products have been shown to provide convenient synthetic access to γ-hydroxy hydrazide, γ-amino hydrazide, and heterocyclic derivatives.[NiFe]-hydrogenases are used by several human pathogens to catalyze the reversible conversion between molecular hydrogen and protons and electrons. Hydrogenases provide an increased metabolic flexibility for pathogens, such as Escherichia coli and Helicobacter pylori, by allowing the use of molecular hydrogen as an energy source to promote survival in anaerobic environments. With the rise of antimicrobial resistance and the desire for novel therapeutics, the [NiFe]-hydrogenases are alluring targets. Inhibiting the nickel insertion pathway of [NiFe]-hydrogenases is attractive as this pathway is required for the generation of functional enzymes and is orthogonal to human biochemistry. In this work, nickel availability for the production and function of E. coli [NiFe]-hydrogenase was explored through immunoblot and activity assays. Whole-cell hydrogenase activities were assayed in high throughput against a small molecule library of known bioactives. Iodoquinol was identified as a potential inhibitor of the nickel biosynthetic pathway of [NiFe]-hydrogenase through a two-step screening process, but further studies with immunoblot assays showed confounding effects dependent on the cell growth phase.
