Why might negative mood help or hinder inhibitory performance? An exploration of thinking styles using a Navon induction

ABSTRACT Theories of affective influences on cognition posit that negative mood may increase cognitive load, causing a decrement in task performance (Seibert & Ellis, [1991]. Irrelevant thoughts, emotional mood states, and cognitive task performance. Memory & Cognition, 19(5), 507–513), or cause a shift to more analytic thinking, which benefits tasks requiring attention to detail (Schwarz & Clore, [1983]. Mood, misattribution, and judgments of well-being: Informative and directive functions of affective states. Journal of Personality and Social Psychology, 45(3), 513–523). We previously reported that individuals who are higher in the trait of emotional reactivity performed better on an inhibitory task with increasing negative mood whereas low-reactive individuals showed the converse pattern (Gabel & McAuley, [2018]. Does mood help or hinder executive functions? Reactivity may be the key. Personality and Individual Differences, 128, 94–99; [2020]. React to act: Negative mood, response inhibition, and the moderating role of emotional reactivity. Motivation and Emotion, 44(6), 862–869). Because high-reactive individuals are more accustomed to negative affect (Nock et al., [2008]. The emotion reactivity scale: Development, evaluation, and relation to self-injurious thoughts and behaviors. Behavior Therapy, 39(2), 107–116), we speculated that negative mood engendered analytic thinking but without a task-incongruent increase in cognitive load – thereby facilitating performance. Here, we induced a heuristic or analytic approach to information processing prior to performance of an inhibitory task and expected different results pending the thinking style induced. In the heuristic condition, increasing negative mood was associated with better performance for high-reactive participants but not their low-reactive counterparts. In the analytic condition, increasing negative mood was associated with better performance irrespective of emotional reactivity. Our results are consistent with the notion that negative mood engenders analytic thinking which may benefit response inhibition provided it does not increase task-incongruent cognitive load.
NCAPH promotes cell proliferation and inhibits cell apoptosis of bladder cancer cells through MEK/ERK signaling pathway

ABSTRACT Bladder cancer (BC) is one of the most common cancers world-wide with a poor prognosis. Non-SMC (Structural Maintenance of Chromosomes)-condensin I complex subunit H (NCAPH) is a regulatory subunit of the condensin I complex and plays an important role in tumorigenesis and progression in several types of cancers. However, the role of NCAPH in BC remains unknown. In this study, we tried to reveal the biological functions of NCAPH in BC. We detected the expressions of NCAPH in BC and adjacent tissues, and BC cells lines. Subsequently, the gain- and loss-of-function experiments were performed to determine the effects of NCAPH on BC cell proliferation, apoptosis, and activation of the MEK/ERK signaling pathway in vitro. Moreover, we used BALB/c nude mice and established a xenograft model to investigate whether silence NCAPH using shRNA targeting NCAPH (shNCAPH) can inhibit BC tumor growth in vivo. The results showed NCAPH was overexpressed in BC tissues compared to adjacent tissues and highly expressed in BC cell lines. Additionally, overexpression of NCAPH promoted cell proliferation and inhibited apoptosis in SW780 cells. Conversely, knockdown of NCAPH reduced cell proliferation and enhanced apoptosis in UMUC3 cells. Furthermore, we found that the NCAPH activated the MEK/ERK signaling pathway in BC cells. MEK1/2 inhibitor U0126 blocked the increase of cell proliferation regulated by NCAPH overexpression. Knockdown of NCAPH significantly inhibited tumor growth in mice. Our results suggest that NCAPH might play an important role in BC progression and provide the potential marker in the diagnosis of BC.
Digestive recovery of polyphenols, antioxidant activity, and anti-inflammatory activity of selected edible flowers from the family Fabaceae.

Edible flowers are regaining popularity as therapeutic agents, due to their phytochemical composition. The present study assessed the recovery of phenolics along with the antioxidant and anti-inflammatory properties of seven edible flowers of the Fabaceae family after being subjected to simulated gastrointestinal conditions and dialysis. The total phenolic content of all the flowers decreased after the gastric phase, whereas the total flavonoid content increased. The total anthocyanin content of four flower species decreased after the intestinal phase of digestion. Cassia auriculata expressed the highest hydrogen peroxide and nitric oxide scavenging activities in the dialyzed fraction. Bauhinia racemose had the highest activity in the inhibition of heat-induced hemolysis of red blood cells after dialysis (4.43 ± 01.5%). In general, the results suggest a reduction in the phenolic contents after gastrointestinal digestion and dialysis; however, phenolics, flavonoids and anthocyanins were sufficiently available to be absorbed with the dialysis to exert antioxidant and anti-inflammatory activities. PRACTICAL APPLICATION: The presence of various phenolic compounds in edible flowers has attracted the attention of consumers as well as the food industry, due to their potential to be incorporated in functional foods and drugs. However, the availability of phenolics after digestion is an important measure to get a realistic view of the health effects exerted upon the consumption of these edible flowers. The present study provides new information on the antioxidant and anti-inflammatory potential of selected edible flowers before and after in vitro digestion. This would be more useful for nutritionists, policymakers and consumers to effectively utilize edible flowers by understanding the changes undergone by the phenolic compounds upon digestion.
Investigation of intermolecular interactions and binding mechanism of PU139 and PU141 molecules with p300 HAT enzyme via molecular docking, molecular dynamics simulations and binding free energy analysis

Abstract The p300 histone acetyltransferase (HAT) enzyme acetylates the lysine residue of histone promotes the transcription reaction. The abnormal function of p300 HAT enzyme causes various diseases such as Cancer, Asthma, Alzheimer, Diabetics, and AIDS. In the recent years, several studies have been conducted to design potential drug to inhibit this enzyme. Recently, an in vitro study has been performed on the synthetic molecules PU139 and PU141 to inhibit the p300 HAT enzyme. The present study aims to understand the binding affinity, intermolecular interactions, conformational stability and binding energy of PU139 and PU141 molecules in the active site of p300 HAT enzyme from the in silico studies. The molecular docking and molecular dynamics (MD) simulations were carried out for both ligands with the p300 HAT enzyme. The molecular docking and MD simulations reveals that both molecules forms expected interactions with the catalytic site key residues of p300 enzyme. The MD simulation shows the maximum RMSD value for the PU141 is 2.3 Å, whereas for PU139 is 3.3 Å; these low RMSD values indicate that both molecules are highly stable in the active site of p300. The calculated binding free energy of PU141 (−20.62 kcal/mol) is higher than the molecule PU139 (−17.67 kcal/mol). Among the results, PU141 shows the high binding affinity with p300 while comparing with PU139. The results of this in-silico study coupled with the findings reported in the in vitro study confirm that PU141 may be suitable for clinical study. Communicated by Ramaswamy H. Sarma
Radiation affects glutathione redox reaction by reduced glutathione peroxidase activity in human fibroblasts

Abstract The glutathione (GSH) redox control is critical to maintain redox balance in the body’s internal environment, and its perturbation leads to a dramatic increase in reactive oxygen species (ROS) levels and oxidative stress which have negative impacts on human health. Although ionizing radiation increases mitochondrial ROS generation, the mechanisms underlying radiation-induced late ROS accumulation are not fully understood. Here we investigated the radiation effect on GSH redox reactions in normal human diploid lung fibroblasts TIG-3 and MRC-5. Superoxide anion probe MitoSOX-red staining and measurement of GSH peroxidase (GPx) activity revealed that high dose single-radiation (SR) exposure (10 Gy) increased mitochondrial ROS generation and overall oxidative stress in parallel with decrease in GSH peroxidase (GPx) activity, while GSH redox control was effective after exposure to moderate doses under standard serum conditions. We used different serum conditions to elucidate the role of serum on GSH redox reaction. Serum starvation, serum deprivation and DNA damage response (DDR) inhibitors-treatment reduced the GPx activity and increased mitochondrial ROS generation regardless of radiation exposure. Fractionated-radiation was used to evaluate the radiation effect on GSH reactions. Repeated fractionated-radiation induced prolonged oxidative stress by down-regulation of GPx activity. In conclusion, radiation affects GSH usage according to radiation dose, irradiation methods and serum concentration. Radiation affected the GPx activity to disrupt fibroblast redox homeostasis.
Plasticity impairment exposes CA3 vulnerability in a hippocampal network model of mild traumatic brain injury

Proper function of the hippocampus is critical for executing cognitive tasks such as learning and memory. Traumatic brain injury (TBI) and other neurological disorders are commonly associated with cognitive deficits and hippocampal dysfunction. Although there are many existing models of individual subregions of the hippocampus, few models attempt to integrate the primary areas into one system. In this work, we developed a computational model of the hippocampus, including the dentate gyrus, CA3, and CA1. The subregions are represented as an interconnected neuronal network, incorporating well‐characterized ex vivo slice electrophysiology into the functional neuron models and well‐documented anatomical connections into the network structure. In addition, since plasticity is foundational to the role of the hippocampus in learning and memory as well as necessary for studying adaptation to injury, we implemented spike‐timing‐dependent plasticity among the synaptic connections. Our model mimics key features of hippocampal activity, including signal frequencies in the theta and gamma bands and phase‐amplitude coupling in area CA1. We also studied the effects of spike‐timing‐dependent plasticity impairment, a potential consequence of TBI, in our model and found that impairment decreases broadband power in CA3 and CA1 and reduces phase coherence between these two subregions, yet phase‐amplitude coupling in CA1 remains intact. Altogether, our work demonstrates characteristic hippocampal activity with a scaled network model of spiking neurons and reveals the sensitive balance of plasticity mechanisms in the circuit through one manifestation of mild traumatic injury.
Flow Visualization and Leakage Measurements of Stepped Labyrinth Seals: Part 1 — Annular Groove

An improved understanding of a new category of stepped labyrinth seals, which feature a new “annular groove”, was obtained. A water leakage and flow visualization test facility of very large scale (relative to a typical seal) was utilized. Flow visualization experiments using a new method and digital facilities for capturing and editing digital images from an 8 mm video were conducted. The presence of an annular groove machined into the stator land increases the leakage resistance by up to 26 percent for the cases considered here. Tracer particles show the degree of throughflow path penetration into the annular groove (i.e. serpentining), which gives the largest and the smallest leakage resistance improvement over that of the corresponding conventional stepped seal.Copyright © 1996 by ASME
Minimally Invasive “Trocar-Free” Approach for Rear Mandibular Fractures Management

Abstract: The request of minimally invasive surgery is progressively expanding the indications of endoscopically assisted intraoral access for mandibular traumas. The aim of our study is to assess how much the use of the angled drill may affect the outcome of patients treated for rear mandibular fracture. In our retrospective case-control trial we enrolled 36 patients with mandibular rear fractures treated through endoscopically assisted intraoral access. Eighteen patients were treated by using an angled drill ‘‘trocar free,’’ and 18 treated by linear drills placed through trocars. Surgical times, hospitalization times (HT), and major complications rate were compared between the 2 groups. Group 1 showed a significant reduction in HT (1.72 versus 2.22 days, P = 0.024) and an increase in the surgical times (3.0 versus 2.53 hours, P = 0.019). Significant reduction of total amount of complication was seen in group 1 versus group 2 (P = 0.007). The ‘‘trocar free’’ approach allowed by angled drills, in our hands, greatly reduces the invasiveness of the surgery resulting in a significant reduction in HT and smaller share of vascular-nervous sequelae. Our results suggest the ‘‘trocar free’’ approach as a valuable choice when indicated for the treatment of rear mandibular fractures.
Guilt as an Influencer in End-of-Life Care Decisions for Nursing Home Residents With Advanced Dementia.

The concept of guilt has been studied in the context of caregivers of older adults with advanced dementia, usually describing the feelings a person has of placing a loved one in a long-term care facility; however, little research has been done to understand how nursing home staff and proxies for older adults with dementia describe guilt as a decision-influencer in end-of-life care. For the current study, private, semi-structured interviews were conducted with 158 nursing home staff and 44 proxies in 13 nursing homes across four demographic regions in the United States. Interviews were reviewed and analyzed for how the concept of guilt was perceived as a decision-influencer. Nursing home staff described guilt as an important influencer in why proxies make decisions about end-of-life care. Staff noted that proxies who felt guilty about their relationship with their loved one or lack of time spent at end-of-life tended to be more aggressive in care decisions, whereas no proxies mentioned guilt as an influencer in care decisions. Rather, proxies used language of obligation and commitment to describe why they make decisions. Findings highlight the disconnect between nursing home staff and proxies in what motivates proxies to make end-of-life decisions for loved ones. Nursing home staff should be aware of misconceptions about proxies and work to understand proxies' true rationale and motivations for making care decisions.

Sharing health information across online platforms: A systematic review

ABSTRACT Advanced Web 2.0 communication technologies have facilitated health-related information (HRI) sharing on the Internet. Especially, the COVID-19 pandemic and lockdowns around the world have forced more people to turn to the Internet for HRI. A better understanding of users’ sharing content and sharing behavior can help communicators improve health literacy, raise community awareness, and facilitate social support exchanges. This paper reports the results of a systematic review of online HRI sharing literature, including key research topics, theories and methods used in past studies, and key factors of sharing behavior across online platforms. Following the PRISMA procedure for a systematic review, 58 articles were identified and analyzed using keyword matching, thematic analysis, and expert review. Guided by the platform theory, our findings differentiated five types of online platforms that differently influenced online users’ sharing content and sharing purposes, including micro-blogs, social network sites, online health communities, social question and answer sites, and Wikis. The findings also clarify five main research topics and applicable theories used in each topic, including personal health sharing, health-related knowledge sharing, general health message diffusion, outcomes of HRI sharing, and exploratory research. Key factors of sharing behavior and potential sharing outcomes are also reviewed and summarized in the research framework developed from the motivation theory. Our study contributes to the understanding of online sharing behavior and provides implications for health communicators to develop effective health campaigns. Potential research directions are also identified and discussed.
Crocin ameliorates atherosclerosis by promoting the reverse cholesterol transport and inhibiting the foam cell formation via regulating PPARγ/LXR-α

ABSTRACT Crocin (CRO) is feasible in alleviating atherosclerosis (AS), the mechanism of which was therefore explored in the study. High-fat diet (HFD)-induced apolipoprotein E-deficient (ApoE−/−) mice and lysophosphatidic acid (LPA)-treated macrophages received CRO treatment. Treated macrophage viability was determined via MTT assay. In both murine and macrophage, the lipid level and total Cholesterol/Cholesteryl l Ester (TC/CE) levels were quantified by oil-red-O staining and ELISA, respectively. Lipid droplet, aortic plaque formation and collagen deposition were detected via Oil-red-O staining, hematoxylin–eosin staining and Masson staining, respectively. Liver X Receptor-α (LXR-α), Peroxisome Proliferator-Activated Receptor γ (PPARγ), CD68, PCSK9, CD36, ATP Binding Cassette Subfamily A Member 1 (ABCA1), phosphorylated (p)-AKT, and AKT expressions were detected via Western blot, the former three also being detected using Immunohistochemistry and the first being measured by qRT-PCR. CRO decreased HFD-induced weight gain, ameliorated the abnormal serum lipid levels of HFD-treated mice, and inhibited aortic plaque formation and lipid deposition, and increased collagen fibers, with upregulated high-density lipoprotein-cholesterol (HDL-C) and downregulated TC and low-density lipoprotein-cholesterol (LDL-C). CRO alleviated the HFD-induced upregulations of CD68, PCSK9 and CD36 as well as downregulations of PPARγ/LXR-α, ABCA1 and AKT phosphorylation. In LPA-treated macrophages, CRO alone exerted no effect on the viability yet inhibited the lipid droplets formation and downregulated TC/CE levels. Silent LXR-α reversed the effect of CRO on the lipid droplets formation and levels of lipid metabolism-related factors. CRO ameliorated AS by inhibiting foam cells formation and promoting reverse cholesterol transport via PPARγ/LXR-α.
Design for an Evolving Patient Experience

I recently saw notice of a journal with which I was not familiar. SAGE, which publishes Health Environments Research & Design Journal (HERD), has an open access, peer-reviewed Journal of Patient Experience. Since my research area focuses mostly on critical care, I noticed the call for papers on “Patient’s Experience in the Intensive Care Unit” which is due December 31, 2021. That caused me to give some thought to the whole idea of patient experience.
Dietary Sodium, Potassium, and Sodium to Potassium Ratio in Patients With Systemic Lupus Erythematosus

Purpose: The aim of this study was to investigate the association between dietary sodium, potassium, and sodium:potassium ratio and clinical disease activity parameters, damage accrual, and cardiovascular disease risk factors in a population of patients with systemic lupus erythematous (SLE). Research design and study sample: A cross-sectional study including a total of 280 patients was conducted (90.4% females; mean age 46.9 ± 12.85 years). Data collection: The SLE Disease Activity Index (SLEDAI-2K) and the SDI Damage Index were used to assess disease activity and disease-related damage, respectively. A 24-hour diet recall was used to estimate dietary intake of sodium and potassium. Results: Dietary sodium intake was significantly associated with anti-dsDNA (β = −.005; 95% CI [.002 .008]; p = .001) and complement C4 level (β = −.002; 95% CI [−.003, .000]; p = .039). Dietary potassium intake was also significantly associated with complement C3 level (β = −.004; 95% CI [−.007, −.001]; p = .021). Multiple logistic regression models revealed a positive association between dietary sodium intake and the risk of having hsCRP > 3 (p = .005) and an inverse association between dietary potassium intake and the risk of having hsCRP > 3 (p = .004). Conclusions: SLE patients with higher dietary sodium and lower dietary potassium intakes had an increased risk of higher hsCRP. Dietary sodium intake was significantly associated with anti-dsDNA and complement C4 level, while dietary potassium intake was associated with complement C3 level, supporting that dietary sodium and potassium intakes might play a key role in markers related to disease activity in SLE patients.
Relating to the end of life through advance care planning: Expectations and experiences of people with dementia and their family caregivers

Background Dementia is widely considered a progressive condition associated with changes in cognitive capacities, which promotes the idea that people with dementia need to anticipate end-of-life care preferences. There is a growing body of interventions meant to support advance care planning (ACP) for people with dementia and their families. However, a deeper understanding of their experiences and expectations regarding planning the end of life is needed to inform ethically sound and person-centered ACP. This study explores how end-of-life care planning for people with dementia is experienced and perceived in practice. Methods We conducted a secondary analysis of qualitative data from in-depth interviews and ethnographic fieldwork. Participants included people with dementia living in the community or in nursing homes, family caregivers, and professional caregivers. During reflective sessions, the researchers moved back and forth between their original data and overarching topics related to ACP. Both performed deductive coding to filter relevant information from their data. Ongoing discussions allowed for the fine-tuning of themes. Results End-of-life care planning for people with dementia can encompass a paradox of control. While it may foster a sense of being in control, it may also feel like relinquishing control over future situations. It raises concerns regarding responsibility, as present, former and future wishes may not align. Family caregivers are often responsible for concrete end-of-life decision-making, prompting them to weigh previous wishes against present situations. Further, people with dementia may wish to focus on the present and distance themselves from the future. Discussion Advance decisions about end-of-life care are often decontextualized and people may find it difficult to oversee their future conditions and preferences. The widely recognized purpose of ACP to exert control over end-of-life care may need revision to match the needs of people with dementia while they are coping with their condition and an uncertain future.
