Comparison of an Acute Bout of Exercise to a Sugary Snack on Energy, Mood and Cognitive Performance

Low perceived energy and a decline in cognitive performance throughout the day are common issues, though exercise and food consumption are suggested to improve mood and cognition. The present study compares effects of acute exercise to consuming sugar on mood, energy, and cognitive performance. Subjects underwent blood glucose testing, completed an Abbreviated Profile of Mood States Questionnaire, and Automated Operation Span (OSPAN) and Digit Span tests to measure memory and attention. On two separate days subjects consumed candy or walked on a treadmill for 10 minutes, then measurements were repeated at 30-min, 60-min, and 120-min post. Two-way ANOVA over time revealed significant condition over time effects for the maximum digits on the forward digit span (p=0.034) and number of correct spans in the backward digit span (p=0.023). There were no significant differences for OSPAN performance, mood or perceived energy (p\u3e0.05). This study indicates that though exercise and sugar have limited differences in their effects there is a need for greater research in this area

Music and Language: Exploring an Artificial Music Grammar

Research regarding the brain mechanisms that underlie music and language processing supports two main interpretations: domain-specificity and domain-generality. Evidence from neuropsychology literature, specifically from amusia research, supports domain-specific mechanisms (Peretz & Coltheart, 2003) but recent neuroimaging and behavioral evidence supports overlapping mechanisms, especially for syntax processing (Patel, 2008). The present study used an artificial music grammar in order to test participants\u27 ability to learn a new music grammar as well as to observe a possible interaction between music and language syntax processing. Although participants were able to learn the artificial music grammar, a language task was not affected by errors in the new grammar as has been found with Western music-syntax errors (Sieve, Rosenberg, & Patel, 2009). Future research should consider extending exposure to the artificial grammar to allow for better learning in order for errors in the new grammar to affect the processing of language syntax

The Relationship Health and Attractiveness Self-Ratings with Body Satisfaction and Health Behavior

‘Trigger Theory’ suggests that for a discrepancy to act as a trigger, the discrepancy must be interpreted as a ‘threat’ to an important self-concept or self-view. Triggering events have been cited as important sparks for weight loss and control behaviors in women, but only certain discrepancies result in a triggering event. The purpose for this study was to determine if there was a relationship between self-rated attractiveness and health with body mass index (BMI) self-esteem, weight satisfaction, dietary intake, and physical activity (PA). A relationship would indicate a role of both attractiveness and health self-views in self-concept and self-esteem, thus preferred self-views to examine in the future experimental research of Trigger Theory. Online surveys were distributed to 461 women who wanted to lose or maintain body weight. The surveys included self-reports of height and weight, which were used to calculate BMI. Self-ratings of attractiveness and health were developed from the Self-Conceptions Questionnaire, asking participants to rate their own physical attractiveness and physical health relative to others her age and gender. Responses ranged from bottom 5% to top 5%. The Global PA Questionnaire assessed PA, and only the total minutes per week of moderate to vigorous PA were used in the study. Dietary intake was assessed through a food frequency questionnaire, where foods were averaged into two factors of interests, fruits/vegetables and high fat/high sugar foods. Weight satisfaction was determined using a 5- point scale from 1 (extremely dissatisfied) to 5 (extremely satisfied). For global self-esteem, women rated how strongly they agreed or disagreed with, “I see myself as someone who has high self-esteem,” on a 5-point scale from 1 (strongly disagree) to 5 (strongly agree). Both self-ratings of attractiveness and health positively correlated with weight satisfaction and self-esteem. The higher one’s self-rating of attractiveness and health, the higher her satisfaction with weight and self-esteem. In addition, self-ratings of attractiveness and health were negatively correlated with BMI. These results support the theory that self-ratings can be greatly valued factors that, when threatened, become the motivators needed to influence changes in health behaviors. The weak correlation of PA and dietary intake with self-views of health suggests that those who see themselves as healthy in comparison to others their age (a part of their self-concept) might be more active and eat healthier. The lack of correlation of PA and dietary intake with self-views of attractiveness suggests that there is no relationship between how attractive one thinks she is, and how active she is or how healthy she eats. It is possible, then, that women can maintain or improve how attractive they think they are without engaging in healthy behaviors, such as through camouflaging their body with clothes and other methods

Ground Contact Time Imbalances Strongly Related to Impaired Running Economy

Running economy (RE) is defined as the oxygen consumption (VO2) or caloric unit cost required to move at a specific velocity and is an important performance marker. Ground contact time (GCT) has been associated with RE; however, it has not been established how GCT imbalances between feet impact RE. Purpose: Determine the relationship between cadence, GCT, and GCT imbalances and RE. Methods: 11 NCAA Division I distance runners (7 male) completed a graded exercise test on a treadmill to determine lactate threshold (LT) and VO2max. Body composition was also assessed via DEXA. Subjects ran with a heart rate monitor capable of measuring cadence, GCT, and GCT balance between feet. VO2 and respiratory exchange ratio were recorded over the last minute of the 5-minute stages. RE expressed as caloric unit cost (kcal·kg-1· km-1) was calculated for the stage determined to be just below the LT (prior to \u3e 4mmol/L) and was correlated with cadence, GCT, and GCT imbalance by Pearson correlations. Results: Pearson correlations between RE and the running dynamics measures were as follows: cadence (r = -.444, p = .171), GCT (r = .492, p = .125), GCT Imbalance (r = .808, p \u3c .005). An independent t-test revealed greater (p = .023) leg lean mass imbalances in runners with larger GCT imbalances compared to runners with smaller GCT imbalances. Conclusion: GCT imbalances are strongly related to impaired RE. Future research should determine how to improve GCT imbalances and if doing so improves RE

A Decade of FGF Receptor Research in Bladder Cancer: Past, Present, and Future Challenges

Fibroblast growth factors (FGFs) orchestrate a variety of cellular functions by binding to their transmembrane tyrosine-kinase receptors (FGFRs) and activating downstream signalling pathways, including RAS/MAPK, PLCγ1, PI3K, and STATs. In the last ten years, it has become clear that FGF signalling is altered in a high proportion of bladder tumours. Activating mutations and/or overexpression of FGFR3 are common in urothelial tumours with low malignant potential and low-stage and -grade urothelial carcinomas (UCs) and are associated with a lower risk of progression and better survival in some subgroups. FGFR1 is not mutated in UC, but overexpression is frequent in all grades and stages and recent data indicate a role in urothelial epithelial-mesenchymal transition. In vitro and in vivo studies have shown that FGFR inhibition has cytotoxic and/or cytostatic effects in FGFR-dependent bladder cancer cells and FGFR-targeted agents are currently being investigated in clinical studies for the treatment of UC. Urine-based tests detecting common FGFR3 mutations are also under development for surveillance of low-grade and -stage tumours and for general population screening. Overall, FGFRs hold promise as therapeutic targets, diagnostic and prognostic markers, and screening tools for early detection and clinical management of UC

Reinterpreting radiocarbon records in bamboo corals ? New insights from the tropical North Atlantic

Deep-sea bamboo corals (family Isididae) have been used as archives for reconstructing changes in the past ocean. However, uncertainties remain regarding the interpretation of geochemical signals from their organic nodes, specifically the water depth of the signals recorded by the coral. Here we explore this question by measuring radiocarbon (14C) and nitrogen (15N) isotopic compositions of the organic nodes in six bamboo corals collected from the central and eastern tropical Atlantic between 700 m and 2000 m water depth. By comparing coral 14C to measured seawater data, regional shallow-water coral records and climate-model outputs, we find contrasting results between the two regions. Our bamboo coral 14C results from the eastern tropical Atlantic support previous studies that suggest organic node carbon is sourced primarily from the mixed layer of the ocean. By contrast, the 14C of bamboo coral organic nodes from the oligotrophic central Atlantic better correlates with the 14C content of the subsurface deep chlorophyll maximum layer rather than the surface mixed layer. Combined with nitrogen isotope data, this observation suggests that sinking and/or ambient zooplankton feeding on phytoplankton from the deep chlorophyll maximum layer can contribute a significant proportion of the diet of bamboo corals. These results suggest that the carbon source for bamboo corals organic nodes may not always reside in the mixed layer, especially in oligotrophic regions, which has implications for 14C-based age model development in bamboo corals

Is Persistent Motor or Vocal Tic Disorder a Milder Form of Tourette Syndrome?

BACKGROUND: Persistent motor or vocal tic disorder (PMVT) has been hypothesized to be a forme fruste of Tourette syndrome (TS). Although the primary diagnostic criterion for PMVT (presence of motor or vocal tics, but not both) is clear, less is known about its clinical presentation. OBJECTIVE: The goals of this study were to compare the prevalence and number of comorbid psychiatric disorders, tic severity, age at tic onset, and family history for TS and PMVT. METHODS: We analyzed data from two independent cohorts using generalized linear equations and confirmed our findings using meta‐analyses, incorporating data from previously published literature. RESULTS: Rates of obsessive–compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD) were lower in PMVT than in TS in all analyses. Other psychiatric comorbidities occurred with similar frequencies in PMVT and TS in both cohorts, although meta‐analyses suggested lower rates of most psychiatric disorders in PMVT compared with TS. ADHD and OCD increased the odds of comorbid mood, anxiety, substance use, and disruptive behaviors, and accounted for observed differences between PMVT and TS. Age of tic onset was approximately 2 years later, and tic severity was lower in PMVT than in TS. First‐degree relatives had elevated rates of TS, PMVT, OCD, and ADHD compared with population prevalences, with rates of TS equal to or greater than PMVT rates. CONCLUSIONS: Our findings support the hypothesis that PMVT and TS occur along a clinical spectrum in which TS is a more severe and PMVT a less severe manifestation of a continuous neurodevelopmental tic spectrum disorder. © 2021 The Authors.

A laboratory-scale annular continuous flow reactor for UV photochemistry using excimer lamps for discrete wavelength excitation and its use in a wavelength study of a photodecarboxlyative cyclisation

This paper describes a new annular reactor for continuous UV photochemistry, which uses easily interchangeable excimer lamps of different wavelengths. The reactor has narrow clearance to form thin films of material for efficient irradiation of molecules. Its use is demonstrated by investigating the effect of discrete wavelength lamps (222, 282 and 308 nm) on the reaction of potassium N-phthalimidobutanoate 1. The ability of the reactor to be integrated into multistep processes is illustrated by combining it with an Amberlyst scavenger and a solid acid catalyst, NbOPO4, to access a second product 3 that is obtained in a single telescoped process. The tricyclic scaffold in 3 is a motif found in several biologically active compounds and has possibilities as a synthon for new pharmaceutical products
