Human Amygdala Tracks a Feature-Based Valence Signal Embedded within the Facial Expression of Surprise

Published: September 2017

Human amygdala function has been traditionally associated with processing the affective valence (negative vs positive) of an emotionally charged event, especially those that signal fear or threat. However, this account of human amygdala function can be explained by alternative views, which posit that the amygdala might be tuned to either (1) general emotional arousal (activation vs deactivation) or (2) specific emotion categories (fear vs happy). Delineating the pure effects of valence independent of arousal or emotion category is a challenging task, given that these variables naturally covary under many circumstances. To circumvent this issue and test the sensitivity of the human amygdala to valence values specifically, we measured the dimension of valence within the single facial expression category of surprise. Given the inherent valence ambiguity of this category, we show that surprised expression exemplars are attributed valence and arousal values that are uniquely and naturally uncorrelated. We then present fMRI data from both sexes, showing that the amygdala tracks these consensus valence values. Finally, we provide evidence that these valence values are linked to specific visual features of the mouth region, isolating the signal by which the amygdala detects this valence information.SIGNIFICANCE STATEMENTThere is an open question as to whether human amygdala function tracks the valence value of cues in the environment, as opposed to either a more general emotional arousal value or a more specific emotion category distinction. Here, we demonstrate the utility of surprised facial expressions because exemplars within this emotion category take on valence values spanning the dimension of bipolar valence (positive to negative) at a consistent level of emotional arousal. Functional neuroimaging data showed that amygdala responses tracked the valence of surprised facial expressions, unconfounded by arousal. Furthermore, a machine learning classifier identified particular visual features of the mouth region that predicted this valence effect, isolating the specific visual signal that might be driving this neural valence response.

Published: September 2017

Absztrakt:
A vékonybél daganatai ritkák, az egész béltraktus daganatainak 1–5%-át képezik. A
vékonybél leggyakoribb malignus daganatai az adenocarcinoma, lymphoma és a
neuroendokrin tumorok. Ritkábban előforduló daganatok közé tartoznak a
gastrointestinalis stromalis tumorok (GIST), a leiomyosarcoma és a leiomyoma. A
leiomyoma leggyakrabban a jejunumban fordul elő, ezt követi az ileum és a
duodenum. A legtöbb esetben ezen tumorok diagnózisát műtét előtt nagyon nehéz
felállítani. A műtéti kezelés lehetőségei duodenalis tumorok esetén lokális
excisio, szegmentális duodenumreszekció és pancreaticoduodenectomia. Ezen jól
differenciált tumorok prognózisa relatíve jó. A szerzők egy 61 éves férfi esetét
tárgyalják, aki duodenalis tumor miatt került felvételre. Panaszai három
hónappal felvétele előtt kezdődtek, amelyek periodikusan jelentkező
epigastrialis tompa fájdalom és hányás volt. A benignus duodenalis tumor
excisiójára került sor, és a beteg a műtétet követő hetedik napon hagyta el a
kórházat panaszmentesen. A szerzők a duodenalis leiomyomáról közölt irodalmi
adatokat is áttekintik.

Authors: Shareghi Bita , Johanson Per-Erik , Kärrholm Johan 
Published: September 2017

Background:
In an earlier study with a 2-year follow-up of uncemented cups, we had reported low femoral-head penetration of vitamin E-infused highly cross-linked polyethylene liners (E1) compared with highly cross-linked liners without vitamin E (ArComXL). We studied the penetration rate of E1 compared with that of ArComXL, with a focus on changes occurring between 2 and 5 years after total hip arthroplasty.

Methods:
In this randomized controlled study, we performed radiostereometric analysis of the penetration rate up to 5 years in 63 hips.

Results:
During the total period of observation, the median proximal penetration for E1, 0.13 mm (mean, 0.11 mm [95% confidence interval (CI), 0.08 to 0.14 mm]), was lower than that for ArComXL, 0.20 mm (mean, 0.22 mm [95% CI, 0.17 to 0.26 mm]). The median proximal penetration rate between 2 and 5 years was 0.02 mm/yr (mean, 0.01 mm/yr [95% CI, 0.01 to 0.02 mm/yr]) for E1 and 0.04 mm/yr (mean, 0.04 mm/yr [95% CI, 0.03 to 0.05 mm/yr) for ArComXL. The corresponding median total (i.e., 3-dimensional resultant) penetration rates were 0.04 mm/yr (mean, 0.04 mm/yr [95% CI, 0.03 to 0.05 mm/yr]) for E1 and 0.07 mm/yr (mean, 0.08 mm/yr [95% CI, 0.06 to 0.10 mm/yr]) for ArComXL.

Conclusions:
From years 2 to 5, we observed increased penetration in both groups. The penetration rate was higher for ArComXL, resulting in more proximal and total penetration at 5 years than for E1.

The Opportunity Awaits to Lead Orthopaedic Telehealth Innovation
Authors: Wongworawat Montri D. , Capistrant Gary , Stephenson John M. 
Published: September 2017

Abstract:
Telehealth is a way to provide health-care services to a patient from a provider who is at another location. The most common methods include a live interactive visit with the patient, interpretation of imaging, and monitoring of patient progress. Principally, telehealth is a way of providing a service rather than a type of service. It is about patient care, not data care.
Examples of orthopaedic applications include conducting patient examinations, interpreting imaging studies, and providing postoperative care. Teleconsultation has been shown to be cost-effective. Other examples in orthopaedic research include the application of telemedicine when measuring patient-reported outcomes. Especially in cases when the patient lives far away from the provider, telehealth reduces time, produces good patient satisfaction, and costs less than hands-on care. As in everyday life, consumers have learned to demand convenience, ease of use, choice, control, and direct access. The ubiquity of telecommunications, combined with consumer technology savviness, drives the demand for telehealth. Unfortunately, the nation’s largest payer for health services is one of the most restrictive for telehealth coverage. Medicare’s restrictions are mostly the work of the U.S. Congress under Part B law. Video visits are very narrowly covered. Another major policy barrier is that interstate telehealth requires multiple state licenses for the physician, who must be licensed in the jurisdiction of each patient as well as the provider’s physical locations. As Medicare shifts toward capitated payment and other value-based methods, there are opportunities to remove such restrictions.
Despite these challenges, some states have been proactive in implementing telehealth systems. Arkansas is one of these states, and being a rural state with 2 main population centers, specialty care is relatively sparse. Implemented in 2014, the hand trauma program has been a partnership between the University of Arkansas for Medical Sciences (UAMS) and the Arkansas Trauma Communications Center (ATCC). This program has been very successful in decreasing the rate of hand trauma transfer, allowing patients to be treated closer to home while having coordinated access to fellowship-trained hand surgeons when necessary.
More widespread innovation of orthopaedic applications for telehealth requires physician buy-in and health-systems partnerships. The regulatory environment will need streamlining. Ultimately, consumer demand will drive the implementation of technology to make care more accessible, convenient, and cost-effective.
Muscle Microvascular Blood Flow, Oxygenation, pH, and Perfusion Pressure Decrease in Simulated Acute Compartment Syndrome
Authors: Challa Sravya T. , Hargens Alan R. , Uzosike Amarachi , Macias Brandon R. 
Published: September 2017

Background:
The current gold standard for diagnosing acute compartment syndrome (ACS) is an assessment of clinical signs, invasive measurement of intramuscular pressure (IMP), and measurement of local perfusion pressure. However, IMP measurements have several shortcomings, including pain, risk of infection, risk of technique error, plugging of the catheter tip, lack of consensus on the diagnostic pressure threshold, and lack of specificity and sensitivity. The objective of this study was to evaluate muscle hemodynamics, oxygenation, and pH as diagnostic parameters in a human model of ACS. We hypothesized that as IMP increases, muscle microvascular blood flow, oxygenation, and pH decrease in the anterior compartment of a leg at heart level and that they decrease significantly more when the leg is elevated further.

Methods:
An external pneumatic leg pressure chamber, combined with a venous stasis thigh cuff, was used to increase IMP and simulate ACS. Eight healthy subjects (5 males and 3 females; mean age, 26 years) had photoplethysmography and near-infrared spectroscopy-pH sensors placed over the middle aspect of the tibialis anterior muscle of the right (experimental) and left (control) legs. Leg chamber pressure conditions (40, 50, and 60 mm Hg) were applied in a randomized order after baseline measurements were taken. Data were collected continuously for each 11-minute pressure condition, with an 11-minute recovery period after each condition, and the average of the last 6 minutes was used for data analyses. The same protocol was repeated with each subject’s legs elevated 12 cm above heart level. Data were analyzed using repeated-measures analysis of variance (ANOVA).

Results:
As IMP increased, muscle microvascular blood flow (p = 0.01), oxygenation (p < 0.001), and pH (p < 0.001) all decreased significantly in the experimental leg compared with the control leg. At all IMP levels, leg elevation significantly decreased muscle oxygenation (p = 0.013) and perfusion pressure (p = 0.03) compared with the control leg at heart level.

Conclusions:
These results indicate that muscle microvascular blood flow, oxygenation, pH, and perfusion pressure decrease significantly as IMP increases in a human model of ACS.

Clinical Relevance:
This study identifies hemodynamic and metabolic parameters as potential noninvasive diagnostic tools for ACS.
Just Curious: How Can Academic Libraries Incite Curiosity to Promote Science Literacy?
Authors: Yu Siu Hong 
Published: September 2017

Based on a Bright Young Minds webinar given on February 7, 2017, this paper shows the importance of nurturing curiosity in students as an integral part of information literacy (IL) and science literacy. There are obvious parallels between "Research as Inquiry," as described in the ACRL Framework for Information Literacy for Higher Education (2016) and scientific inquiry. In both cases, curiosity is the fuel that drives information gathering and the pursuit of new knowledge. This paper discusses three pedagogical strategies to help information literacy librarians incite curiosity in students and promote scientific literacy. Bright Young Minds is a webinar series hosted by the Ontario Library Association’s Education Institute. It provides a platform for MLIS students and recent graduates to share their research and to foster connections between academic schools and information professionals. The webinar and this subsequent article grew out of an MLIS project exploring the concept of curiosity and its application in promoting scientific literacy in academic libraries. I draw on my dual experiences as both a Chemistry graduate student and participant in IL sessions, and as a recent MLIS graduate and IL instructor.
Basé sur le webinaire « Bright Young Minds » offert le 7 février 2017, cet article montre l’importance de favoriser la curiosité auprès des étudiants comme élément essentiel de la formation documentaire et de l’enseignement des sciences. Il existe des parallèles évidents entre la notion de « recherche comme enquête », telle que décrite dans le « Framework for Information Literacy for Higher Education (2016), » et la recherche scientifique. Dans les deux cas, la curiosité mène la recherche documentaire et la poursuite de nouvelles connaissances. Cet article présente trois stratégies pédagogiques pour aider les bibliothécaires de formation documentaire à inciter la curiosité auprès des étudiants ainsi que promouvoir la recherche scientifique. « Bright Young Minds » est une série de webinaires offert par l’Education Institue de la Ontario Library Association.

Published: September 2017

Abstract
This paper discusses and compares the potential application of the evidential belief function model and fuzzy logic inference system technique for spatial delineation of a groundwater artesian zone boundary in an arid region of central Iraq. First, a flowing well inventory of a total of 93 perennial flowing wells was constructed and randomly partitioned into two data sets: 70% (65 wells) for training and 30% (28 wells) for validation. Twelve groundwater conditioning factors were considered in the geospatial analysis depending on data availability and literature review. The random forest (RF) algorithm was first applied to investigate the most important conditioning factors in groundwater potential analysis. The most important factors with training flowing wells were used to develop predictive models. The prediction accuracy of the developed models was checked using the area under the relative operating characteristic curve. Results showed that the best model with a higher prediction accuracy of 86% was a fuzzy AND model followed by the evidential model with 84%. The main conclusion of this study is that the integrated use of the adapted models with RF offer a rapid assessment tool in groundwater exploration and can be helpful in groundwater management.

Authors: Zhou Bi-Hui , He Wei-Ping , Li Lin-Lin , Fan Li-Mei , Li Xiang-Rong , Li Jie 
Published: September 2017

Aims and Objectives: When compared to five-membered N-heterocyclic carbene, recent reports
have demonstrated that ring expanded NHCs showed rather different properties such as increased basicity (nucleophilicity)
and greater steric demand. These unique features provide an opportunity to design new chiral
ligands. This study was undertaken to design and synthesize a series of novel enantiopure pyrimidone salts, the
precursors of N-heterocyclic carbenes, and their activity in asymmetric diethylzinc addition of arylaldehydes
was demonstrated as well.

Materials and Method:
Commercially available dimethylmalonic acid was treated with thionyl chloride to form
dimethylmalony dichloride, followed by subsequent reaction with different chiral primary amine produced corresponding
diamide. Next, conversion of diamide to monoamide was achieved by partial reduction with lithium
aluminum hydride. Finally, cyclization of monoamide with triethyl orthoformate in the presence of ammonium
salts provided pyrimidone salts in good yields.

Results:
Seven enantiopure pyrimidone salts, the precursors of N-heterocyclic carbenes, have been synthesized
starting from dimethylmalonic acid. Their applicability in asymmetric diethylzinc addition of arylaldehydes has
been demonstrated and the corresponding secondary alcohol was obtained with good yields and moderate
enantioselectivities.

Conclusion:
Herein we developed an efficient route to prepare a series of novel N-heterocyclic carbene precursors,
which were demonstrated as effective catalysts for asymmetric diethylzinc addition of arylaldehydes, and
the corresponding secondary alcohol was obtained with good yields and moderate enantioselectivities.
