Authors: Gucciardi Enza , Hill Stephanie , Gingras Jacqui
Published: December 2021

Objective: The purpose of this study was to examine the lived experiences of university students with type 1 diabetes mellitus.

Methods: University students participated in a 2-part focus group. Transcripts were analyzed thematically using an open-coding approach. Data analysis was guided by a framework analysis method and emergent themes were triangulated between study authors for validity.

Results: Three major themes identified in this study were food issues within the university environment, lack of diabetes awareness on campus and internal struggles related to the participants' relationships with their diabetes.

Conclusions: Results illustrate some of the unique challenges that interfere with diabetes self-management, academic performance and quality of life among this sample of university students. Findings can provide insight for diabetes educators and other healthcare practitioners regarding the issues that may interfere with optimal diabetes self-care in this population. Findings also can be used to inform university administrators how to make the university environment more diabetes friendly for its students.
Relation Extraction With Clause-Based Open Information Extraction
Authors: Vo Duc Thuan
Published: December 2021

Information Extraction (IE) is one of the challenging tasks in natural language
processing. The goal of relation extraction is to discover the relevant segments of
information in large numbers of textual documents such that they can be used for
structuring data. IE aims at discovering various semantic relations in natural language
text and has a wide range of applications such as question answering, information
retrieval, knowledge presentation, among others. This thesis proposes approaches for
relation extraction with clause-based Open Information Extraction that use linguistic
knowledge to capture a variety of information including semantic concepts, words, POS
tags, shallow and full syntax, dependency parsing in rich syntactic and semantic
structures.
Within the plethora of Open Information Extraction that focus on the use of
syntactic and dependency parsing for the purposes of detecting relations, incoherent
and uninformative relation extractions can still be found. The extracted relations can be
erroneous at times and fail to have a meaningful interpretation. As such, we first
propose refinements to the grammatical structure of syntactic and dependency parsing
with clause structures and clause types in an effort to generate propositions that can be
deemed as meaningful extractable relations. Second, considering that choosing the most
efficient seeds are pivotal to the success of the bootstrapping process when extracting
relations, we propose an extended clause-based pattern extraction method with selftraining for unsupervised relation extraction. The proposed self-training algorithm
relies on the clause-based approach to extract a small set of seed instances in order to
identify and derive new patterns. Third, we employ matrix factorization and
collaborative filtering for relation extraction. To avoid the need for manually predefined schemas, we employ the notion of universal schemas that is formed as a collection of patterns derived from Open Information Extraction tools as well as from
relation schemas of pre-existing datasets. While previous systems have trained relations
only for entities, we exploit advanced features from relation characteristics such as
clause types and semantic topics for predicting new relation instances. Finally, we
present an event network representation for temporal and causal event relation
extraction that benefits from existing Open IE systems to generate a set of triple
relations that are then used to build an event network. The event network is
bootstrapped by labeling the temporal and causal disposition of events that are directly
linked to each other. The event network can be systematically traversed to identify
temporal and causal relations between indirectly connected events.
Queen Of The Bands: Carnival And “Monarchy” In The (416)
Authors: Barnwell Chante
Published: December 2021

Queen of the Bands: Carnival and “Monarchy” in the (416) is a solo multimedia gallery
installation which explores the complexity of Queenliness through the audio and photographic
documentation of four women who perform as the head female masqueraders within the complex
political framework of Toronto Caribbean Carnival's 2017 King and Queen competition. The
Canadian national narrative reserves Queenliness for historically dominant European figures
such as the Queen of England, so what does it mean to be a woman of colour performing as a
queen in a Canadian carnival celebration? The complexity of this history and the prominence of
African masking traditions in carnival Mas’ making, among other cultural influences in the
Caribbean, contribute to the notion of Queenliness within the framework of carnival.
The purpose of my photographic investigation is both to capture a tangible element of
carnival’s relationship to Emancipation Day history in Toronto and, among other things, to
examine the women’s representation and power in Afro-Caribbean communal celebrations. My
additional objectives were the following: First, to evaluate how the historical framework of
Emancipation Day in Ontario has shaped the current production of these celebrations in Toronto.
Second, to contextualize the head female masquerader’s position within the historical framework
of emancipation and carnival. Third, to determine the role carnival celebrations play in defining a
racialized woman’s identity in Canadian society. Fourth, to investigate how employing
documentary photography practices can shape the understanding of Emancipation Day and contextualize African Canadian history. Lastly, to investigate the effect British monarchal
representation in Canada has on Queenliness when performed by women of colour.

Published: December 2021

With considering sewage pipe network upgrading projects in the “villages” in cities, the optimization of construction resources and the assessment of delay risks could be achieved. Based on the schedule-cost hypothetical theory, the mathematical model with constraint indicators was established to obtain the expression of optimal resource input, and conclude the method to analyze the schedule uncertainties. The analysis showed that cyclical footage of pipe could be regarded as a relatively fixed value, and the cost can be regarded as a function that depending on the number of working teams. The optimal number of teams and the optimal schedule occurred when the minimum total cost achieved. In the case of insufficient meteorological data, the Monte Carlo simulation method and uncertainty analysis method can be applied to assess the impact of rainfall on the total construction period, correspondingly the probability of such risk could be derived. The calculation showed that the risk of overdue completion varied significantly according to the construction starting time. It was necessary to take rainfall risk into consideration and make corresponding strategies and measures.
SHOW-CASING INDICATORS TO A CHANGING ORGANIZATIONAL CULTURE THROUGH THE DEVELOPMENT OF AN INTEGRATED ELEARNING MODEL: INDICATIONS OF A CHANGING ORGANISATIONAL CULTURE AT THE UNIVERSITY OF THE WESTERN CAPE (UWC)
Authors: Stoltenkamp Juliet
Published: December 2021

The adoption of technology to enhance teaching and learning in Higher Education Institutions (HEIs) has resulted in institutions having to contend with dynamic changes emanating from the increasing demands to change and improve upon the traditional modes of instruction. This has put pressure on HEIs to implement organisational cultural changes as they seek to incorporate technology in their teaching and learning discourses. The place of models within the education discourse has been more pronounced in recent years in response to the increasing call for practitioners to deliver quality education. The principal thrust of this paper therefore is to highlight the main developmental phases towards the creation of an integrated eLearning model as it seeks to influence organisational cultural change within a case-study of HEI learning environment at the University of the Western Cape for the period September 2005 – October 2011. It is a challenge to move an organisation, particularly a large organisation, and if there isn’t a sense of common direction, one will find a lack of focus (Claret, 2006, p.2). Strategic plans are often associated with transitions in leadership or the attainment of certain milestones (Claret, 2006, p.3). This has been an accumulative exercise at the start of the E-learning Awareness Campaign. Accordingly the replication of such a model would also enhance exchange of ideas as HE practitioners continuously seek to improve the success rate of eLearning implementation.

THE INFLUENCE OF FREE PRIMARY EDUCATION ON KENYA CERTIFICATE OF PRIMARY EDUCATION PERFORMANCE IN KENYA
Authors: Kikechi Ronald Werunga , Kisebe Chepkwony Silas M. , Gitahi Kihumba , Sindabi Oliver
Published: December 2021

The origin of Free Primary Education (FPE) can be traced back to the 1948 Declaration of Human Rights where basic education was recognized as a human right. The current FPE programme was launched in 2003 and it led to an overwhelming enrolment of pupils at the primary level of education. Such a soaring enrolment is feared to have compromised the Kenya Certificate Primary Education (KCPE) performance, which is a key indicator of quality education. The study therefore aimed at determining the influence of high enrolment on; the ability of teachers to offer quality instruction; learning resources; management of pupils’ discipline and suggestion on how to improve FPE in light of KCPE performance. The paper assessed FPE on KCPE performance in Kaptama Division, Mt. Elgon District, Kenya. The researcher used descriptive survey design. A sample of 310 respondents consisting of 253 standard eight pupils, 40 teachers, 13 head teachers and 4 education officers was used. The main tools of data collection were a questionnaire and interview schedule. Document analysis was also used in the study. Data analysis involved the use of frequencies, percentages, tables, chart, graphs and description. The findings of the study established that implementation of FPE led to high enrolment which witnessed high pupil - teacher ratio and ill-discipline among pupils. It has also led to inadequate learning facilities (classrooms, desks and chairs), fewer tests for pupils which lack in content and depth and increased work load among teachers. This has in turn compromised KCPE performance. Constant inspection should be carried out by the Ministry of Education for the success of the programme.

Desigualdades, exclusiones y (dis) continuidades pedagógicas. Escenarios educativos en pandemia
Authors: Sulca Elisa Martina de los Ángeles
Published: December 2021

La pandemia del COVID-19 obligó a «quedarse en casa» y ante ello, estudiar, trabajar, entretenerse se trasladaron al espacio del hogar en formato virtual. Esta abrupta transición expuso crudamente la desigualdad matricial e histórica de nuestras sociedades. En este artículo se ofrecen reflexiones críticas en torno a las condiciones materiales y simbólicas en las que tiene lugar la continuidad escolar de estudiantes indígenas en contextos rurales del norte argentino. La investigación socioeducativa centrada en la experiencia escolar de jóvenes indígenas desarrollada antes de la pandemia (2019) y el Informe Nacional Efectos socioeconómicos y culturales de la pandemia COVID-19 y del aislamiento social, preventivo y obligatorio en los Pueblos Indígenas del país, Anexo XVII, Salta (2020) son las fuentes que nos permiten construir las argumentaciones de este trabajo. Pensar y analizar la escuela antes y durante la pandemia es una necesidad imperiosa para empezar a proyectarla como un espacio de justicia social, probablemente el único que incluya a estudiantes de los sectores más vulnerables después de esta experiencia social inédita.

Incongruity of Nationalisms? Interactions between Korean National History and American Historians of Korea, the 1910s to 1980s
Authors: Tikhonov Vladimir
Published: December 2021

The heuristic starting point for this paper is a critical approach to the enterprise of modern historiography per se, based on the understanding of it as inherently bound by teleological epistemology. While “Korean nationalism” is the usual vantage point for the critique of modern Korean historiography, the current article attempts to reverse this analytical perspective and re-assess a number of attempts to write on Korean history by US-based historians of Korea in the 1910s–1980s as reflections of inherently self-centric picture of the world. In this Eurocentric picture, traditional Korea was locked into a historical trajectory via which “modernity” was unachievable.
Side wind and tank speed influence on lateral displacement of the projectile
Authors: Sorokatiy M. , Voytovych M. , Velychko L. , Moskalova O.
Published: December 2021

This article indicates the scope of the formula for determining the magnitude of the lateral displacement of the projectile under the action of crosswind, which is used in the compilation of firing tables.

This formula is valid under the following conditions: the force of frontal air resistance to the motion of the projectile is proportional to the its velocity squared; wind speed components are much smaller than the horizontal component of projectile velocity; the projectile velocity projections on the Oy and Oz axes are much smaller than the projections on the Ox axis; the dimensionless coefficient of resistance and the magnitude of the crosswind are constant values.

However, in reality, the force of frontal air resistance to the motion of the projectile is only sometimes proportional to the its velocity squared; the projectile velocity projections on the Oz axis may be are much smaller than the projections on the Ox axis and may even be greater than it; the coefficient of resistance is depends on the value of the Makh number, so it can be considered constant only when shooting at short distances.

The authors propose a mathematical model for determining the magnitude of the lateral displacement of the projectile under the action of crosswinds. It is believed that the force of the crosswind on the projectile depends on the following factors: air density; the maximum area of the longitudinal section of the projectile; the difference between the value of the lateral component of the wind speed and the speed of the lateral displacement of the projectile, which is raised to a certain power.

The magnitude of the values of the lateral displacement of the projectile under the action of the crosswind when shooting at short distances, determined based on the proposed mathematical model, slightly differ from the values of the lateral displacement specified in the firing tables.

However, with increasing firing distance, the difference between these values is constantly increasing and the value of the lateral displacement of the projectile determined theoretically is much larger than indicated in the firing tables. In addition, in this research the influence of the tank velocity on the value of the projectile lateral displacement taking into account the action of the crosswind is studied.

Published: December 2021

The operation of the BMP-2 infantry fighting vehicle was accompanied by periodic failures of the tracked belts. This is due to the breakage of the fixing bolts of the track pins fastening bracket, and thus the military equipment became stationary. Establishing the causes of the destruction of the bolt fixing the staple of the track fingers of the tracked belt of military equipment was carried out using a complex of instrumental materials science research. In particular, the chemical composition of the material from which the bolts and staples were made was determined by the spectral analysis; the fracture surface of the fixing bolt was investigated by the macroanalysis; the microstructure of the bolts was examined using optical microscopy; the microhardness and density of the bolt material was measured. The bolts were made from steel grades 30XM and 33XC, and not from the recommended steel grade 38XC. The macrostructure of the broken bolt corresponds to the shearing structure. The microstructure showed rolling and heat treatment defects. Density measurement confirmed the presence of heat treatment defects. The imperfection of the applied heat treatment was confirmed by measuring the microhardness. A complex of metallurgical research has established the main cause of the destruction of the bolts. It consists in an unsuccessful design of bolts and brackets, an incorrectly selected steel grade with defects in rolling and heat treatment.

Bu çalışmada 2005-18 yılları arasında Türkiye’de enflasyonun gelir eşitsizliğine etkisi Türkiye İstatistik Kurumu tarafından uygulanan Hanehalkı Bütçe Anketi ile Gelir ve Yaşam Koşulları Anketinden elde edilen iki mikro veri seti kullanılarak incelenmektedir. Farklı gelir seviyelerindeki hanehalklarının yaptıkları harcamaların ana harcama gruplarına dağılımı dikkate alınarak gelir seviyelerine göre hanehalklarının karşı karşıya kaldıkları yıllık enflasyon oranları tespit edilmiştir. Bu oranlar aracılığıyla hanehalklarının reel gelirleri belirlenmiştir. Hanehalklarının reel gelirleri kullanılarak önemli eşitsizlik ölçütleri olan Gini katsayısı ve yüzde payları ile göreli yoksulluk oranı hesaplanmıştır. Hem hanehalkı kullanılabilir gelire göre hem de eşdeğer hanehalkı kullanılabilir fert gelirine göre reel gelir dağılımındaki eşitsizliğin, Türkiye İstatistik Kurumu tarafından açıklanan eşitsizlikten daha yüksek olduğu tespit edilmiştir. 2005-18 döneminde enflasyonunun gelir dağılımının bozulmasında belirgin bir etkiye sahip olduğu ve yüksek ve düşük gelire sahip hanehalkı grupları arasındaki gelir makasının kapanmasını engellediği sonucuna ulaşılmıştır.

Authors: Dolgov I. M. , Volovik M. G.
Published: December 2021

The purpose of the study was to find out if infrared thermography of the thorax is the method to select the patients with lung inflammation

Material, methods: Thermograms were accumulated and processed in the «TVision» cloud storage («Dignosis», Russia). Special regions of interest (ROI) were automatically created: 1. on the front and back of the thorax roughly in the projection of the upper lobe (ULP) and the lower lobe (LLP) of the lung; 2.e lines on the front surface of the thorax. Two types of temperature gradients were calculated: between ULP and LLP (by subtraction mean temperature in LLP from mean temperature in ULP) (ΔT1); between both ULP and both LLP on the back of the thorax (ΔT2). Approximation confidence value for the polynomial trend line (R²) along the marked lines on the front surface of the thorax also calculated. Totally 489 thermograms, were analyzed, included 337 from healthy patients (group 1) and 152 from patients with confirmed diagnosis of lung inflammation (group 2)

Results: R² value was higher in the group 1 compare to group 2 (0.58 ± 0.16 vs 0.3 ± 0.2, p < 0.05). ΔT1 value was negative only in patients from group 2, as well as ΔT1 value greater than 0.4 °C.

Conclusion: three independent thermographic criteria suitable for detecting lung inflammation were found, so infrared thermography is the valuable method for screening this pathology.

USOS ESPECÍFICOS DE RECURSOS DAS TECNOLOGIAS DIGITAIS NAS FASES DE UMA ATIVIDADE DE MODELAGEM MATEMÁTICA
Authors: Souza Henrique Cristiano Thomas de
Published: December 2021

Considerando as funções de uso dos recursos das tecnologias digitais elencadas na literatura, nesse artigo investigamos como usos específicos dos recursos das tecnologias digitais foram contemplados nas fases de desenvolvimento de atividades de modelagem matemática. Para tal, analisamos uma sequência de atividades de modelagem matemática desenvolvidas na disciplina de Modelagem Matemática no Ensino oferecida no 5º período de um curso de Licenciatura em Matemática. Na análise crítica-reflexiva identificamos e descrevemos como funções específicas de uso dos recursos das tecnologias digitais são utilizadas nas fases de uma atividade de modelagem matemática. Concluímos que nem todos os usos específicos dos recursos das tecnologias digitais foram contemplados em uma fase qualquer das que constituem o desenvolvimento de uma atividade de modelagem matemática. Isso se deu, pois, alguns destes usos possuem características que os vinculam naturalmente a uma ou mais fases específicas de uma atividade de modelagem matemática, enquanto, outros usos dependem da característica da atividade em desenvolvimento para serem estabelecidos. Contudo, em maior ou menor grau todos os usos estiveram presentes no desenvolvimento das atividades analisadas.
Elastic Rhythm in Signal-Synchronised Sequencing Objects for Pure Data
Authors: Kelly Edward
Published: December 2021

This paper presents a family of objects for manipulating polyrhythmic sequences and isorhythmic relationships, in both the signal and event domains. These work together and are tightly synchronised to an audio phase signal, so that relative temporal relationships can be tempo-manipulated in a linear fashion. Many permutations of polyrhythmic sequences including incomplete tuplets, scrambled elements, interleaved tuplets and any complex franctional relation can be realised. Similarly, these many be driven with controllable isorhythmic generators derived from a single driver, so that sequences of different fractionally related lengths may be combined and synchronised. It is possible to use signals to drive audio playback that are directly generated, so that disparate sound files may be combined into sequences. A set of sequenced parameters are included to facilitate this process.

A pesquisa de carácter exploratório, descritivo e de natureza qualitativa, contando com a participação de cinco sujeitos: três professores e duas professoras. Como instrumento de recolha de dados foi usada entrevista semiestruturada para professores, aplicando a análise de conteúdo. A pesquisa está fundamentada, principalmente, nas teorias de Bento (2011), Cavalleiro (2004) e Munanga (2005), que colaboraram para a conclusão de que a criança desde muito cedo passa a conviver com o racismo, e que a escola é responsável, em parte, pela construção e disseminação das relações de preconceito étnico-racial.
Suicídio a longo prazo? Estudo sobre uma moralidade xintoísta nos Skilled Veterans Corps
Authors: Lopes Ricardo Cortez
Published: December 2021

O artigo lida com as concepções morais dos Skilled Veterans Corps, idosos que se ofereceram para trabalhar nos vazamentos do acidente nuclear de Fukushima, ocorrido em 2011 na sequência de um terremoto e de um tsunami. Partindo de uma sociologia durkheimiana, analisamos as ideias expressas em declarações partindo do conceito de suicídio. O resultado da análise apontou para a emergência de dois pilares na sua argumentação: uma forte noção de comunidade e a figura do antepassado protetor, as quais remontam diretamente à religião xintoísta. Assim, os veteranos estão argumentando com o governo de maneira secularizada, porém partindo de bases morais religiosas culturalizadas, algo que origina uma crítica decolonial.
Effects of Tai-Chi Chuan Practice on Patterns and Stability of Lower Limb Inter-Joint Coordination During Obstructed Gait in the Elderly
Authors: Kuo Chien-Chung , Chen Sheng-Chang , Wang Jr-Yi , Ho Tsung-Jung , Lin Jaung-Geng , Lu Tung-Wu
Published: December 2021

Losing balance or tripping during obstacle-crossing is one of the most frequent causes of falls in the elderly. As a low speed, low impact exercise, Tai Chi Chuan (TCC) can be promising in helping the elderly develop strategies for improved balance, inter-joint coordination, and end-point control during obstacle-crossing. This study investigates the effects of TCC training on the patterns and variability of the lower-limb inter-joint coordination during obstacle-crossing in the elderly. Fifteen older TCC practitioners and 15 healthy controls crossed obstacles of three different heights, while sagittal angles (x) and angular velocities (x′) of the hips, knees and ankles were measured and their phase angles obtained. The continuous relative phases (CRP) of the hip-knee and knee-ankle coordination were also calculated. The standard deviations of the CRP curve points were averaged to obtain deviation phase (DP) values for the stance and swing phases. The TCC group was found to cross obstacles with increased leading and trailing toe-clearances with unaltered CRP values when the swing toe was above the obstacle. Long-term TCC training altered the patterns and magnitudes of the CRPs primarily over double-limb support and significantly reduced the variabilities of leading knee-ankle and trailing hip-knee and knee-ankle CRP curves over the crossing cycle, regardless of obstacle height. The current results suggest that long-term TCC practice was helpful for a crossing strategy with significantly increased foot-obstacle clearances and reduced variability of the way the motions of the lower limb joints are coordinated during obstacle-crossing. These benefits may be explained by the long-lasting effects of continuous practice of the slow movement patterns emphasizing between-limb transfer of body weight in TCC.
Realistic Reference for Evaluation of Vehicle Safety Focusing on Pedestrian Head Protection Observed From Kinematic Reconstruction of Real-World Collisions
Authors: Li Guibing , Liu Jinming , Li Kui , Zhao Hui , Shi Liangliang , Zhang Shuai , Nie Jin
Published: December 2021

Head-to-vehicle contact boundary condition and criteria and corresponding thresholds of head injuries are crucial in evaluation of vehicle safety performance for pedestrian protection, which need a constantly updated understanding of pedestrian head kinematic response and injury risk in real-world collisions. Thus, the purpose of the current study is to investigate the characteristics of pedestrian head-to-vehicle contact boundary condition and pedestrian AIS3+ (Abbreviated Injury Scale) head injury risk as functions of kinematic-based criteria, including HIC (Head Injury Criterion), HIP (Head Impact Power), GAMBIT (Generalized Acceleration Model for Brain Injury Threshold), RIC (Rotational Injury Criterion), and BrIC (Brain Injury Criteria), in real-world collisions. To achieve this, 57 vehicle-to-pedestrian collision cases were employed, and a multi-body modeling approach was applied to reconstruct pedestrian kinematics in these real-world collisions. The results show that head-to-windscreen contacts are dominant in pedestrian collisions of the analysis sample and that head WAD (Wrap Around Distance) floats from 1.5 to 2.3 m, with a mean value of 1.84 m; 80% of cases have a head linear contact velocity below 45 km/h or an angular contact velocity less than 40 rad/s; pedestrian head linear contact velocity is on average 83 ± 23% of the vehicle impact velocity, while the head angular contact velocity (in rad/s) is on average 75 ± 25% of the vehicle impact velocity in km/h; 77% of cases have a head contact time in the range 50–140 ms, and negative and positive linear correlations are observed for the relationships between pedestrian head contact time and WAD/height ratio and vehicle impact velocity, respectively; 70% of cases have a head contact angle floating from 40° to 70°, with an average value of 53°; the pedestrian head contact angles on windscreens (average = 48°) are significantly lower than those on bonnets (average = 60°); the predicted thresholds of HIC, HIP, GAMBIT, RIC, BrIC2011, and BrIC2013 for a 50% probability of AIS3+ head injury risk are 1,300, 60 kW, 0.74, 1,470 × 104, 0.56, and 0.57, respectively. The findings of the current work could provide realistic reference for evaluation of vehicle safety performance focusing on pedestrian protection.

Soft, deformable, molecularly imprinted nanoparticles (nanoMIPs) were combined to nano-plasmonic sensor chips realized on poly (methyl methacrylate) (PMMA) substrates to develop highly sensitive bio/chemical sensors. NanoMIPs (dmean < 50 nm), which are tailor-made nanoreceptors prepared by a template assisted synthesis, were made selective to bind Bovine Serum Albumin (BSA), and were herein used to functionalize gold optical nanostructures placed on a PMMA substrate, this latter acting as a slab waveguide. We compared nanoMIP-functionalized non-optimized gold nanogratings based on periodic nano-stripes to optimized nanogratings with a deposited ultra-thin MIP layer (<100 nm). The sensors performances were tested by the detection of BSA using the same setup, in which both chips were considered as slab waveguides, with the periodic nano-stripes allocated in a longitudinal orientation with respect to the direction of the input light. Result demonstrated the nanoMIP-non optimized nanogratings showed superior performance with respect to the ultra-thin MIP-optimized nanogratings. The peculiar deformable character of the nano-MIPs enabled to significantly enhance the limit of detection (LOD) of the plasmonic bio/sensor, allowing the detection of the low femtomolar concentration of analyte (LOD ∼ 3 fM), thus outpassing of four orders of magnitude the sensitivies achieved so far on optimized nano-patterned plasmonic platforms functionalized with ultra-thin MIP layers. Thus, deformable nanoMIPs onto non-optimized plasmonic probes permit to attain ultralow detections, down to the quasi-single molecule. As a general consideration, the combination of more plasmonic transducers to different kinds of MIP receptors is discussed as a mean to attain the detection range for the selected application field.

Published: December 2021

The regulatory role of actin cytoskeleton on mitochondrial function is a growing research field, but the underlying molecular mechanisms remain poorly understood. Specific actin-binding proteins (ABPs), such as Gelsolin, have also been shown to participate in the pathophysiology of mitochondrial OXPHOS disorders through yet to be defined mechanisms. In this mini-review, we will summarize the experimental evidence supporting the fundamental roles of actin cytoskeleton and ABPs on mitochondrial trafficking, dynamics, biogenesis, metabolism and apoptosis, with a particular focus on Gelsolin involvement in mitochondrial disorders. The functional interplay between the actin cytoskeleton, ABPs and mitochondrial membranes for the regulation of cellular homeostasis thus emerges as a new exciting field for future research and therapeutic approaches.
An Immune Panel Signature Predicts Prognosis of Lung Adenocarcinoma Patients and Correlates With Immune Microenvironment
Authors: Zhou Yuan , Tang Lu , Chen Yuqiao , Zhang Youyu , Zhuang Wei
Published: December 2021

Background: Lung cancer, especially lung adenocarcinoma (LUAD) with high incidence, seriously endangers human life. The immune microenvironment is one of the malignant foundations of LUAD, but its impact at the molecular level is incompletely understood.

Method: A total of 34 LUAD samples from Xiangya Hospital were collected for immune oncology (IO) profiling. Univariate Cox analysis was performed to profile prognostic immune genes based on our immune panel sequencing data. The least absolute shrinkage and selection operator (LASSO) algorithm was applied to construct a risk signature. The cut-off threshold of risk score was determined using X-tile software. Kaplan–Meier survival curves and receiver operating characteristic (ROC) curves were employed to examine the performance of this risk signature for predicting prognosis. The immune infiltration was estimated using a single-sample gene set enrichment analysis (ssGSEA) algorithm.

Result: Thirty-seven immune genes were profiled to be significantly correlated with the progression-free survival (PFS) in our cohort. Among them, BST2, KRT7, LAMP3, MPO, S100A8, and TRIM29 were selected to construct a risk signature. Patients with a higher risk score had a significantly shorter PFS (p = 0.007). Time-dependent ROC curves indicated that our risk signature had a robust performance in accurately predicting survival. Specifically, the 6-, 12-, and 18-month area under curve (AUC) was 0.800, 0.932, and 0.912, respectively. Furthermore, the risk signature was positively related to N stage, tumor stage, and tumor malignancy. These results were validated using two external cohorts. Finally, the risk signature was significantly and uniquely correlated with abundance of neutrophil.

Conclusion: Our study revealed an immune panel-based signature that could predict the prognosis of LUAD patients and was associated with the infiltration of neutrophils.

Mass spectrometry imaging (MSI) serves as an emerging tool for spatial profiling of metabolic dysfunction in ischemic tissue. Prior to MSI data analysis, commonly used staining methods, e.g., triphenyltetrazole chloride (TTC) staining, need to be implemented on the adjacent tissue for delineating lesion area and evaluating infarction, resulting in extra consumption of the tissue sample as well as morphological mismatch. Here, we propose an in situ ratiometric MSI method for simultaneous demarcation of lesion border and spatial annotation of metabolic and enzymatic signatures in ischemic tissue on identical tissue sections. In this method, the ion abundance ratio of a reactant pair in the TCA cycle, e.g., fumarate to malate, is extracted pixel-by-pixel from an ambient MSI dataset of ischemic tissue and used as a surrogate indicator for metabolic activity of mitochondria to delineate lesion area as if the tissue has been chemically stained. This method is shown to be precise and robust in identifying lesions in brain tissues and tissue samples from different ischemic models including heart, liver, and kidney. Furthermore, the proposed method allows screening and predicting metabolic and enzymatic alterations which are related to mitochondrial dysfunction. Being capable of concurrent lesion identification, in situ metabolomics analysis, and screening of enzymatic alterations, the ratiometric MSI method bears great potential to explore ischemic damages at both metabolic and enzymatic levels in biological research.

The massive burning of a large amount of fossil energy has caused a lot of serious environmental issues (e.g., air pollution and climate change), urging people to efficiently explore and valorize sustainable alternatives. Biomass is being deemed as the only organic carbon-containing renewable resource for the production of net-zero carbon emission fuels and fine chemicals. Regarding this, the selective transformation of high-oxygen biomass feedstocks by catalytic transfer hydrogenation (CTH) is a very promising strategy to realize the carbon cycle. Among them, the important Meerwein-Ponndorf-Verley (MPV) reaction is believed to be capable of replacing the traditional hydrogenation strategy which generally requires high-pressure H2 and precious metals, aiming to upgrade biomass into downstream biochemical products and fuels. Employing bifunctional heterogeneous catalysts with both acidic and basic sites is needed to catalyze the MPV reaction, which is the key point for domino/cascade reaction in one pot that can eliminate the relevant complicated separation/purification step. Zirconium (Zr) and hafnium (Hf), belonging to transition metals, rich in reserves, can demonstrate similar catalytic efficiency for MPV reaction as that of precious metals. This review introduced the application of recyclable heterogeneous non-noble Zr/Hf-containing catalysts with acid-base bifunctionality for CTH reaction using the safe liquid hydrogen donor. The corresponding catalysts were classified into different types including Zr/Hf-containing metal oxides, supported materials, zeolites, metal-organic frameworks, metal-organic hybrids, and their respective pros and cons were compared and discussed comprehensively. Emphasis was placed on evaluating the bifunctionality of catalytic material and the key role of the active site corresponding to the structure of the catalyst in the MPV reaction. Finally, a concise summary and prospect were also provided centering on the development and suggestion of Zr/Hf-containing acid-base bifunctional catalysts for CTH.
