Baseline Left Ventricular Strain as a Prognostic Tool for Stress Echocardiography Outcomes
Authors: Biondi * , Moseley * , Wells * , Harris David , Quimby Donald
Published: May 2023

Background: Left ventricular (LV) strain in echocardiography
has been utilized as a determinant of myocardial function and a
predictor of LV dysfunction prior to a reduction in ejection fraction.
However, it is not known if changes in baseline LV strain can predict
ischemia. Methods: This single center retrospective study at
the University of Cincinnati aimed to evaluate the predictive value of
baseline LV global longitudinal strain (GLS) obtained prior to stress
echocardiogram (sEcho) for detecting myocardial ischemia in moderate
risk patients undergoing evaluation for coronary artery disease (CAD).
The study included 118 patients who underwent sEcho for CAD evaluation.
Baseline LV GLS was measured in the apical 4 chamber, apical 2 chamber,
and parasternal long axis views using Phillips or General Electric
machines. Patients were divided into two groups based on pre-stress GLS
values: GLS < -16% (n=67, 56.8%) and GLS ≥ -16% (n=51,
43.2%). Results: The mean age of the patients was 53.6±12.1
years, 55.9% were women, and 31.4% belonged to a non-white racial or
ethnic group. The average baseline GLS values were -19.1%±2.4 and
-13.5%±2.0 for patients in the GLS < -16% and GLS ≥ -16%
baseline strain groups, respectively. Overall, 5.1% of the study
population had a positive sEcho. Only one patient with GLS <
-16% had a positive sEcho (P=0.038). The negative predictive value of
GLS < -16% for a positive stress test was 98.5%.
Conclusions: Assessing baseline LV GLS prior to sEcho could be
a cost-effective and efficient predictor of stress outcomes in
moderate-risk patients undergoing evaluation for CAD. Our results
suggest that a baseline GLS value < -16% has a high negative
predictive value for myocardial ischemia detected by sEcho. However,
larger studies in more diverse populations are needed to confirm these
findings.
Functional proteomics reveals that Slr0237 is a SigE-regulated glycogen debranching enzyme pivotal for glycogen breakdown
Authors: Ge Haitao , Liu Ye , Lu Dandan
Published: May 2023

The group 2 σ factor for RNA polymerase SigE plays important role in
regulating central carbon metabolism in cyanobacteria. However, the
regulation of SigE for these pathways at a proteome level remains
unknown. Using a sigE-deficient strain (ΔsigE) of Synechocystis sp. PCC
6803 and quantitative proteomics, we found that SigE depletion induces
differential protein expression for sugar catabolic pathways including
glycolysis, oxidative pentose phosphate (OPP) pathway, and glycogen
catabolism. Two glycogen debranching enzyme homologues Slr1857 and
Slr0237 are found differentially expressed in ΔsigE. Glycogen
determination indicated that Δslr0237 accumulated glycogen under
photomixotrophic conditions but was unable to utilize these reserves in
the dark, whereas Δslr1857 accumulates and utilize glycogen in a similar
way as the WT strain does in the same conditions. These results suggest
that Slr0237 plays the major role as the glycogen debranching enzyme in
Synechocystis. To our knowledge, this is the first study to report the
functional difference of two glycogen debranching enzyme in
Synechocystis and the research highlights the intricate regulation of
glycogen breakdown.

An analytical micro-macro model of creep fracture driven by cyclic pore pressure in brittle rocks
Authors: Li Xiaozhao , Jia Yaxing , Li Haifeng , Qi Chengzhi
Published: May 2023

Cyclic pore pressure is closely related to the stability and safety of
deep underground engineering. A micro-macro mechanical model of creep
fracture under cyclic pore pressure, external confining pressure, and
axial stress was established to reveal the mechanism of cyclic pore
pressure of brittle rock. The model combines the improved microcrack
model, the function of cyclic pore pressure, the subcritical crack law,
the Hooke-Kelvin model, and the crack-strain model. The complete
elastic, viscoelastic and plastic deformation of rock is described. The
model solution before crack extension determines the elastic and
viscoelastic deformation, and that of after crack extension determines
the plastic deformation. Time-dependent elastic modulus evolution of
rock under cyclic pore pressure is obtained, which affects viscoelastic
strain under cyclic pore pressure. The effects of cyclic pore pressure
parameters ΔP and ΔP and cycle period on rock viscoelastic
rebound value and creep fracture time are discussed. Rationality of the
proposed model is verified by experimental data. The analytical results
provide help for evaluation in safety and stability of rock engineering.
A Hybrid Approach to Computer Aided Drawing Tool for Blind People
Authors: Fernando Sandra , Virdee Bal , Ouazzane Karim
Published: May 2023

Many software development methodologies introduced to date place
users at the centre of development process. Although the user is an
important asset in the software development cycle however the
user-centred approach is not sufficient to develop a software product
that is structurally robust and reliable. User involvement in the
development process does not always guarantee resilience and a more
efficient design. To address this a hybrid-based software development
paradigm is proposed here where the software development cycle includes
a grammar model-based compiler with user-centred approach. The efficacy
of the proposed system is tested with the development of an innovative
computer-aided drawing technology (SETUP09) for blind and visually
impaired people and the results are compared with an existing
non-hybrid-based drawing software (IC2D). The results of this study
confirm SETUP09 improves user satisfaction and provides abstract and
concrete level system flexibility. Provided here are guidelines of the
proposed hybrid approach for software development based on a formal
approach. This hybrid approach enables the software designer to evaluate
the software semantics before user scrutinization. The benefits of the
approach include the facilitation of alternate development pathways
affording the software designer the flexibility to amend the software
without incurring significant technical challenges. In fact, the
proposed approach enables the creation of a structural design that is
independent from the development pathways. This approach should ease the
time constraint in product development and resource constraints.
Existential Depth Analysis: A Framework to Promote Empathic Psychotherapy
Authors: Sickels Michael B.
Published: May 2023

Expanding upon person-centered approaches to understanding empathy, the
author introduces an integrated psychotherapeutic framework, Existential
Depth Analysis (EDA), that uses the four ultimate concerns of
existential psychotherapy (death, freedom, isolation, and
meaninglessness) to facilitate empathic engagement with clients
throughout the therapeutic process. The author also illustrates the
practical applications of EDA in clinical and educational settings.
Keywords: Empathy, existential psychotherapy, person-centered
therapy, four ultimate concerns, accurate empathic understanding
Investigation of retained austenite morphology-dominated hardening and fatigue behavior in bainitic steel during wear process
Authors: Shan Quan , Chen Sida , Huang Xiedong , Liao Zexin , Li Zulai , Wu Hong
Published: May 2023

This study aims to revealing the relationship between retained austenite
(RA) morphology, deformation-induced transformation (DIPT) behavior and
surface wear behavior. The hardening and fatigue behavior during wear of
continuous film-like RA (CFRA), blocky RA (BRA), discontinuous film-like
RA (DFRA) and point or flocculent RA (PRA) achieved through different
tempering process was investigated using quasi-in-situ fatigue test and
impact abrasive wear test. RA morphology exhibited a significant
influence on hardening and fatigue behavior during wear. CFRA exhibited
the best wear properties, owing to its excellent fatigue performance and
hardening capacity. The BRA displayed relative high wear performance,
with adequate hardening capacity but weak fatigue performance. DFRA
demonstrated comparable wear resistance to BRA due to better fatigue
performance. PRA exhibited deficient wear performance due to
insufficient fatigue properties and low work hardening ability.
Leveraging yeast sequestration to study and engineer post-translational modification enzymes.
Authors: Denard Carl , Martinusen Samantha G.
Published: May 2023

Enzymes that catalyze post-translational modifications of peptides and
proteins (PTM-enzymes) – proteases, protein ligases, oxidoreductases,
kinases, and other transferases - are foundational to our understanding
of health and disease and empower applications in chemical biology,
synthetic biology, and biomedicine. To fully harness the potential of
PTM-enzymes, there is a critical need to decipher their enzymatic and
biological mechanisms, develop molecules that can probe and reprogram
them, and endow them with improved and novel functions. These objectives
are contingent upon implementation of high-throughput functional screens
and selections that interrogate large sequence libraries to isolate
desired PTM-enzyme properties. This review discusses the principles of
S. cerevisiae organelle sequestration to study and engineer
PTM-enzymes. These include methods that modify yeast surface display and
employ enzyme-mediated transcription activation to evolve the activity
and substrate specificity of proteases and protein ligases. We also
present a detailed discussion of yeast endoplasmic reticulum (ER)
sequestration for the first time. Where appropriate, we highlight the
major features and limitations of different systems, specifically how
they can measure and control enzyme catalytic efficiencies. Taken
together, yeast-based high-throughput sequestration approaches
significantly lower the barrier to understanding how PTM-enzymes
function and how to reprogram them.
Naloxone blocks social buffering of conditioned fear responses in rats
Authors: Yamasaki Takumi , Kiyokawa Yasushi , Munetomo Arisa , Takeuchi Yukari
Published: May 2023

Social buffering is the phenomenon in which the presence of an
affiliative conspecific mitigates stress responses. We previously
demonstrated that social buffering completely ameliorates conditioned
fear responses in rats. The present study explored the neurochemical
background of this social buffering. In Experiment 1, fear-conditioned
subjects first received an intraperitoneal injection of either naloxone
(non-selective opioid receptor antagonist), haloperidol (dopamine D2
receptor antagonist), SR49059 (vasopressin V1A receptor antagonist),
atosiban (oxytocin receptor antagonist), or saline. The subjects were
then exposed to a conditioned stimulus with an unfamiliar
non-conditioned rat. Naloxone, but not the other three antagonists,
blocked social buffering. In Experiment 2, we assessed the effect of
naloxone on locomotor activity during an open-field test. Naloxone did
not affect walking steps during the test. Therefore, it is unlikely that
the results of Experiment 1 were due to decreased activity by naloxone.
In Experiment 3, we assessed Fos expression in 16 brain regions
accompanied by the blockade of social buffering by naloxone. Consistent
with the results of Experiment 1, Fos expression was increased in the
paraventricular nucleus of the hypothalamus. In addition, Fos expression
was decreased in the nucleus accumbens shell, anterior cingulate cortex,
and insular cortex and tended to be decreased in the nucleus accumbens
core. Naloxone thus appears to affect these four regions and/or act
upstream of these regions during blockade of social buffering. Based on
these results, we conclude that naloxone blocks social buffering of
conditioned fear responses in rats.
The Paraná Magmatic Province: State-of-the-Art in the Geophysical and Geochemical Investigations
Authors: Bologna Mauricio Souza , Rocha Júnior Eduardo Reis Viana , Ernesto Marcia , Marques Leila Soares
Published: May 2023

This paper presents an overview of the present knowledge on the Paraná magmatism and the lithospheric structure under the Paraná Basin. The genesis and diversity of the flood basalt types are linked to the structure and tectonic processes that have affected the crust and upper mantle since the Western Gondwana amalgamation until subsequent rupture. It focuses mainly on the work developed at the Instituto de Astronomia, Geofísica e Ciências Atmosféricas (IAG), Universidade de São Paulo (USP), during five decades, starting from the first detailed paleomagnetic data acquisition along vertical profiles and then associated with the chemical data, a pioneering initiative in the world. Chemical and isotope data were then acquired substantially, allowing advanced knowledge of the sources and genesis of the different magma types. The geophysical studies, including gravity, seismology and electromagnetic induction methods, allowed the recognition of crustal and lithospheric structures and rheology below the sedimentary basin, giving evidence for the magma generation models. Although the aspects addressed here do not run out the subject, it summarizes essential aspects of the present knowledge of the Paraná Magmatic Province.
Leucine Supplementation Ameliorates Early-Life Programming of Obesity in Rats
Authors: Sun Yuchen , Sun Bo , Han Xuesong , Shan Anshan , Ma Qingquan
Published: May 2023

The advanced cessation of lactation elevates the risk of programmed obesity and obesity-related metabolic disorders in adulthood. This study used multiomic analysis to investigate the mechanism behind this phenomenon and the effects of leucine supplementation on ameliorating programmed obesity development. Wistar/SD rat offspring were subjected to early weaning (EW) at day 17 (EWWIS and EWSD groups) or normal weaning at day 21 (CWIS and CSD groups). Half of the rats from the EWSD group were selected to create a new group with 2-month leucine supplementation at day 150. The results showed that EW impaired lipid metabolic gene expression and increased insulin, neuropeptide Y, and feed intake, inducing obesity in adulthood. Six lipid metabolism–related genes (Acot1, Acot2, Acot4, Scd, Abcg8, and Cyp8b1) were influenced by EW during the entire experimental period. Additionally, adult early-weaned rats exhibited cholesterol and fatty acid β-oxidation disorders, liver taurine reduction, cholestasis, and insulin and leptin resistance. Leucine supplementation partly alleviated these metabolic disorders and increased liver L-carnitine, retarding programmed obesity development. This study provides new insights into the mechanism of programmed obesity development and the potential benefits of leucine supplementation, which may offer suggestions for life planning and programmed obesity prevention.

Article Highlights

Early-weaned adult rats showed excess lipid accumulation and metabolic defects. Early weaning disrupts lipid metabolism and secretion of neuropeptide Y and insulin. The altered lipid metabolic gene expression in this study is vital in programming. Leucine mitigates metabolic disorders and hampers programmed obesity development.

OBJECTIVE: There are no commercially available hybrid closed-loop insulin delivery systems customized to achieve pregnancy-specific glucose targets in the United States. This study aimed to evaluate the feasibility and performance of at-home use of a zone model predictive controller based closed-loop insulin delivery system customized for pregnancies complicated by type 1 diabetes (CLC-P).

RESEARCH DESIGN AND Methods: Pregnant women with type 1 diabetes using insulin pumps were enrolled in the second or early third trimester. After study sensor wear collecting run-in data on personal pump therapy and two days of supervised training, participants used CLC-P targeting 80-110 mg/dL during the day and 80-100 mg/dL overnight running on an unlocked smartphone at home. Meals and activities were unrestricted throughout the trial. The primary outcome was the continuous glucose monitoring percentage of time in the target range 63-140 mg/dL versus run-in.

Results: Ten participants (HbA1c 5.8±0.6%) used the system from mean gestational age of 23.7±3.5 weeks. Mean percentage time in range increased 14.1 percentage points, equivalent to 3.4 hours per day, compared to run-in (run-in: 64.5±16.3% versus CLC-P: 78.6±9.2%, P=0.002). During CLC-P use, there was significant decrease in both time over 140 mg/dL (P=0.033) and the hypoglycemic ranges of less than 63 mg/dL and 54 mg/dL (P=0.037 for both). Nine participants exceeded consensus goals of above 70% time in range during CLC-P use. 

ConclusionS: The results show that the extended use of CLC-P at home until delivery is feasible. Larger, randomized studies are indicated to further evaluate system efficacy and pregnancy outcomes.

Published: May 2023

Growing demand for clinical research to improve evidence-based medicine in daily medical practice led to healthcare evaluation, which assesses the effectiveness of the existing care. The first step is identifying and prioritizing the most important evidence uncertainties. A health research agenda (HRA) can be valuable and helps determine funding and resource allocation, aiding researchers and policymakers to design successful research programs and implement the results in daily medical practice. We provide an overview of the development process of the first 2 HRAs within orthopedic surgery in the Netherlands and the following research process. In addition, we developed a checklist with recommendations for the future development of an HRA. This perspective guides the development of highquality and widely supported nationwide HRAs, including preparatory actions. This improves the uptake of evidence uncertainties in a successful research program and disseminates evidence-based literature in daily medical practice to improve patient care.

Published: May 2023

Objective: To appraise research evidence on the effects of balance training on balance and fall efficacy in patients with osteoporosis.Methods: Six electronic databases were searched from inception of the database to 1 August 2022, with no language restrictions, and randomized controlled trials of balance training in patients with osteoporosis were included in this meta-analysis. Two authors independently screened and reviewed the articles and assessed the methodological quality using the Cochrane risk-of-bias tools. Trial sequential analysis was conducted.Results: A total of 10 randomized controlled trials with 684 patients were included. Three of the studies that were included had low risk of bias, 5 had moderate risk of bias, and 2 had high risk of bias. A meta-analysis demonstrated that balance training improves dynamic balance measured using the Timed Up and Go Test (mean difference (MD) = –1.86, 95% CI (–2.69, –1.02), Z = 4.38, p < 0.0001) and the Berg Balance Scale (MD = 5.31, 95% CI (0.65, 9.96), Z = 2.23, p < 0.03), static balance measured using One-Leg Standing Time (MD = 4.10, 95% CI (2.19, 6.01), Z = 4.21, p < 0.0001), and fall efficacy measured using the Falls Efficacy Scale International (MD = –4.60, 95% CI (–6.33, –2.87), Z = 5.20, p < 0.00001) were also significantly improved. Trial sequential analysis showed reliable evidence ofthe effects of balance training on dynamic and static balance improvement. The conclusions of this review are supported by the statistical and clinical significance of all outcomes in the meta-analysis, based on the advised minimal clinically significant differences and minimum detectable changes.Conclusion: Balance training may be effective in improving balance ability and reducing fear of falling in patients with osteoporosis.
LAY ABSTRACTInsufficient balance will limit activities and impair physical and mental capabilities, which will increase the risk of falling and reduce quality of life. The study evidence on the effects of balance training in people with osteoporosis is summarized in this paper. The investigations identified 10 related studies that tested the effects of balance training. The data from these trials shows that balancing training can decrease patients’ fear of falling and improve their balancing abilities. For patients and therapists hoping to enhance the effectiveness of rehabilitation, these findings are crucial.

Considerações sobre a mobilização do conceito de Guardião Constitucional no pensamento de Afonso Arinos de Melo Franco (1960-1967)
Authors: Pereira Wingler Alves
Published: May 2023

Based on the method of analysis of the morphology of political ideologies by Michael Freeden and the conceptual or philosophical history of politics by Pierre Rosanvallon, as well as the theoretical framework related to Brazilian political-constitutional thought, especially liberalism, the article seeks to outline some considerations about the use of the concept of guardian of the Constitution, also defined as moderating power or fourth power, in the thinking of Afonso Arinos de Melo Franco in the unfolding of the Brazilian political crisis that culminated in the military coup of 1964. The work specifically intends to analyze the Melo Franco’s writings and speeches in the temporal arc that covers the period in which he was a senator of the Republic (1960-1967), with the objective of understanding not only the handling of the concept, but his conception regarding three elements of the country, all related to conceptual mobilization: 1) the role of the Federal Supreme Court, in the present and past, to arbitrate political conflicts; 2) the legitimacy of the military to intervene in times of crisis; and 3) the solution of the parliamentary system, defended by him since the 1950s. The article aims, therefore, to explore these three aspects in a contextual and tensioned way to understand the use of the concept.
A desirable privation: Exploring silence as a mode of zoo visiting
Authors: Rice Tom , Reed Adam , Badman-King Alexander , Hurn Samantha , Rose Paul
Published: May 2023

This article describes and discusses a set of exercises in silent zoo visiting conducted at two zoos in the Southwest of the UK in 2019. The visits were part of a wider project on the auditory culture of zoos, institutions which have tended to be analysed by reference to their concern with the visual display of captive other-than-human animals (henceforth animals). Linking ideas on silence that have emerged from work in anthropology and sound studies respectively, the article explores the notion that among many other affordances, silence can generate opportunities for reflection and the consideration of alternatives, in this case in relation to a prevailing zoo visiting culture often characterised by loud anthropogenic sound. Examining extracts and observations from discussions among participants, the article illustrates how this novel form of visiting fostered a variety of types and qualities of experience. It also provided an impetus for participants to notice and focus on specific animals and aspects of animal lives they might not otherwise have considered. Such meditation could foster feelings of connection to particular zoo animals, while also opening up possibilities for more detached contemplation. The silent visits led participants to produce critical perspectives on conventional zoo visiting, and to imagine future possibilities for the auditory culture of zoos. The article shows that silence can serve as a productive methodological tool in the exploration of human-animal relations, and demonstrates how sound is integral to the formation of those relations within, and by implication beyond, the zoo.
Ezekiel, Ethnicity, and Identity
Authors: Nissinen Martti
Published: May 2023

The written sources from the ancient Near East are for the most part authored from the perspective of the dominant group and yield a very limited view on people’s identities from an emic point of view that would correspond to their own self-identification. Self-defined minority groups in Mesopotamia have not left behind written evidence about themselves and their identity strategies. A notable exception to this rule is the book of Ezekiel in the Hebrew Bible. This book documents an intense and enduring attempt at reconstructing the identity of a dislocated group of people. The book of Ezekiel is produced by a group that constructed a diaspora identity from the early sixth century onwards, whether in Babylonia or in Jerusalem; in any case, it is written in an environment where the adaptation of a wide array of Mesopotamian linguistic, iconographic, literary, and theological motifs was possible. Wherever and whenever the book of Ezekiel was produced, it presents itself as a document of an explicit identity strategy of a minority group, unique among written sources from any part of Mesopotamia. It can be read as an example of the survival strategy of a group that distinguishes itself from others by way of self-reidentification. The book does not reflect a stable and universally shared identity of the Judeans. On the contrary, it creates and constructs an inner-Judean antagonism between Ezekiel’s in-group and the delegitimized out-group. The book of Ezekiel, therefore, does not convey much about the integration of the Judean minority into Babylonian society but all the more about conflicts among Judeans themselves.
Greek Inscriptions in Mesopotamia (and Babylonia)
Authors: Ruffing Kai
Published: May 2023

This article provides a short overview on the few Greek inscriptions from Mesopotamia which date to the period between the third century bce and the first century ce. It argues that since the concept of “identity” has certain shortcomings for a historical analysis of an ancient society it might be useful to apply the concepts “commonality,” “connectedness,” and “groupness” for a somehow further and deeper insight. Due to the lack of a larger group of Greek documents in the timeframe mentioned, these concepts are used for some short remarks on the graffiti of the Nebuchelos-Archive from Dura-Europos which dates to the third century ce. The article attempts to show how, in a situation of cultural contact which produced hybrid and ambiguous forms of cultural practices, individuals used different cultural markers and practices of the different societies to demonstrate and publicly display their “commonality” and “connectedness.”
Construction of Identities and Late Mesopotamian Archives as Found in the Fragments of the ‘Graeco-Babyloniaca’
Authors: Lang Martin
Published: May 2023

This article focuses on the social reality behind the so-called Graeco-Babyloniaca, a small sample of less than two dozen fragments of clay tablets, mainly inscribed with cuneiform signs on the obverse, with alphabetic Greek signs on the reverse. As possibly one of the last signs of life of the time-honored cuneiform script, in a Janus-faced manner they hint at the long tradition of Babylonian scholarship and learning on the one hand, and at its disappearance via script-obsolescence on the other. Notwithstanding the fact that there are only a few tablets, the aim of this article is to trace the social group behind the textual remains of the Graeco-Babylonian tablets and tablet fragments.
