Data collection techniques and instruments are interviews, observation and documentation. Testing the validity of the data using source triangulation, technical triangulation and time triangulation. The data analysis technique used is data reduction, data presentation and conclusions. The conclusion of this study is that the teacher's role as a facilitator in cultivating students' interest in reading includes the five indicators. The first is providing learning facilities, the second is providing all learning resources, the third is acting as a partner, the fourth is carrying out the duties and responsibilities of the teacher, the fifth is not acting arbitrarily. Overall the teacher has tried to carry out his role as a facilitator in fostering students' interest in reading. The teacher's obstacle acts as a facilitator in fostering students' interest in reading, namely the lack of interest in reading in students, which originates from the students' ability to read and understand the meaning contained in the reading. Then the teacher also has problems in providing learning facilities, where the role of the library is not maximized and there are limited books or other reading materials. The solution to dealing with the obstacles faced by teachers is to create activities that can increase students' interest in reading and make a group schedule to visit the library. In addition, the teacher also applies learning methods and media that aim to build a conducive classroom atmosphere.

Stimulation of Monetary Policy in the Real Economy
Authors: Panahov F.
Published: July 2023

In order to ensure normal production growth and maximum employment of the population, in practice such regulatory instruments of macroeconomic policy as budgetary-tax (fiscal) and monetary (monetary) ones are used.
Through these regulators of macroeconomic policy, it is possible to achieve the necessary results in the economic and social life of the country in a short time.
The timing of achieving such results is directly related to the rigidity of the application of these regulatory levers.
The more rigid their application, the shorter the time for obtaining the intended results becomes.
The best results in the field of financial stabilization are achieved when all these regulators are used in parallel (jointly), and at the same time this whole process is fully coordinated.

Influencing Student Learning Through a Community-Based Peer Review Process
Authors: Li Shang , Abrantes da Silva Rodrigo , Whiting Jen Story
Published: July 2023

This chapter contains a discussion of the characteristics and features of peer review practices in a community of learners and how the use of peer review as a cognitive tool embedded in a social process improves the learning processes of the reviewers. However, if peer reviews are to be used with the same degree of seriousness as expert reviews, the authors feel it is necessary to prove that they can be equivalent. To that end, the authors compared peer review scores with expert review scores to test if peer reviews are as reliable proportionally as expert reviews. The findings of the data analysis proved that peer review scores are closely correlated to expert review scores, and peer review scores become more reliable when there are more than three peer reviewers.

Published: July 2023

Land use change is generally caused for social, economic, and cultural reasons. Still, it has occurred not only in urban areas but almost all areas, such as upstream watersheds or catchment areas. Land use is a natural resource influenced by soil, climate, topography, and geology that determine the potential for various uses such as natural water sources, agriculture, transportation, and renewable energy. So this study aims to look at changes in land use and factors that influence these changes. The regional boundary is in the form of the Batu-Batu catchment area as the location of the hydropower dam with a capacity of 2x100 megawatts. It is planned to be built. The geographic information system (gis) is used to see land use changes. Land use projections use cellular automata analysis by looking atgrowth trends and targets on landusesimsoftware.landusesim begins with the neighborly process by entering and managing landuse data as an initial transition map into a potential transition map.The catchment areabuttu batu,which affects the dam plan, has an area of 371,191.77 ha. The existing catchment area of buttu batu is dominated by dryland agricultural land in the form of seasonal crops. Land use projections for 100 years see changes in land use area in several classes, the largest occurring in the land use of dryland agricultural areas with an area of 26,092.24 ha or an increase of 94.78%. Landuse in the form of settlements also increased by 3,223.44 ha or with a percentage change of 5.22 percent. Factors influencing land change in the catchment area include road access, settlement, and riverdistance.

This study investigated the influence of the different organic mixtures as soil media use for carrot (Daucus carota L) planted in pots, specifically it investigated how these organic mix influence the growth development and yields of carrots. Complete Randomized Design (CRD) with four treatment and three replicates for each treatments was used which are as follows: T0: Purely Garden Soil (1.75kg GS), T1: 1.25 kg GS + 0.5kg vermicompost (VC), T2: 1kg GS + 0.25kg VC + 0.5 kg cocopeat (CP),T3:1kg GS + 0.25kg VC + 0.25kg CP + 0.25 chicken dung (CD), and T4: 1kg soil compost + 0.25kg VC + 0.25kg CP + 0.25kg CD. The experiment was conducted at the researcher’s house in Mindanao State University faculty cottage, Marawi City. Data collection started 22 days after the seed germination. For growth development, plant height, stem diameter, number of leaves, leaf stalk length and leaf area were measured every week for seven weeks, except for the stem diameter which was only obtained during harvest. Yield was measured through measuring the length diameter, and mass of the carrot taproot. Findings revealed that there is a significant difference among treatments. Treatment 4 shows the highest growth development and yield followed by treatment 3, while treatment 0 or the control shows the lowest growth development and yield. These findings implied that soil compost and chicken dung has the greatest influence to the growth development and yield of potted carrots compared to the other treatments particularly those treatments without chicken dung.

INTEGRATED PHOTOVOLTAIC AND THERMAL SOLAR ENERGY CONVERTER
Authors: Vardanyan R.R. , Karoyan G.S.
Published: July 2023

The utilization of solar energy is essential to curb climate change, reduce dependence on finite fossil fuel reserves, and achieve energy independence. The leading existing technologies for the use of solar radiation are the photovoltaic (PV) conversion of light directly into electricity and the thermal conversion of solar rays into heat. The main problem with solar energy is efficiently collecting this energy and cost-effectively converting it into other useful forms. The existing solar energy systems are still expensive.
The other problem is the decreased efficiency of PV modules at high working temperatures. It is well known, that in PV solar cells, mostly made of silicon, most of the absorbed solar radiation (about 80%) is not converted into electricity but contributes to increasing the temperature of solar cells, then reducing the electrical efficiency of cells. This is the inherent drawback feature of solar cells - degradation in performance due to temperature.
Aiming to reduce the cost of solar converters and to increase solar energy trans-for¬mation efficiency, a new type of Photovoltaic and Thermal (PVT) hybrid solar energy converter is developed in the research laboratory “Photovoltaic Semiconductor Devices” at National Polytechnic University of Armenia. Different innovative approaches are used in developing PVT converters. The prototype of a new type of PVT converter is prepared and tested. The new PVT converter has several advantages in comparison with general PV modules and PV module-based PVT collectors. The production of the developed new PVT collectors is cheap and can be realized using standard off-the-shelf technologies.

In mushroom cultivation enterprise both male and female farmers were engaged in the same manner and even female growers were getting more success. It is easy growing technology, cultivation inside hut, less labour and attracted women farmers also. Farmers were getting high returns from mushroom cultivation but some constraints were reported in its marketing. Due to highly perishability in nature farmers have to sell it within 2-3 days. Male farmers equipped themselves to sell 90% of their product in fresh form and 2% of their produce was sun dried but a total loss of 8% was recorded especially in case of button mushroom as it became black after sun drying. The marketing of fresh mushroom was a major constraint for female farmers as they face problem in going outside for marketing. They were fully dependent on middle men and getting less returns compared to male counterpart. So, they were converting 20-30 % of mushrooms not sold in value added product as dried mushroom, nuggets and pickles. Value added products have long lasting quality so they have to spend more time to sell their product at better price. To extend the freshness time, storage of mushroom in Zero Energy Cool Chamber was also one of the best way, so farmers got extra one or two days to sell their produce and minimize the spoilage.
Continuous T Loop For Correction Of Bimaxillary Protrusion A Case Report
Authors: RATHI SHRITU
Published: July 2023

This case report intends to highlight the space closure with tear drop loop mechanics for bimaxillary protrusion. Loops can be fabricated in a sectional or full arch wire, and closing loops are usually used in loop mechanics for extraction space closure. The major advantage of loop mechanics is the lack of friction between the bracket and arch wire during space closure. An adult patient with bimaxillary protrusion reported to the clinic. The patient was treated successfully by maximum retraction of maxillary and mandibular anterior teeth after extraction of all first premolars. Space closure was begun using a moment differential between posterior and anterior segments created by a Tear drop loop. Anterior teeth were moved with bodily movement, and no anchorage loss of the posterior segments was seen using a Tear drop loop spring. A stable result with normal over jet and overbite was achieved with retraction of maxillary and mandibular anterior teeth. With a Tear drop loop, individual biomechanical responses can be achieved, and it is possible to calculate force magnitude for every patient.

Authors: Lunkes Cesar Augusto
Published: July 2023

O presente trabalho pretende estudar a filosofia política libertarista a partir das principais ideias, princípios e pensamentos defendidos por essa corrente filosófica e doutrinária, buscando avaliar a sua influência no debate que envolve a permissibilidade da interrupção voluntária da gravidez. O objetivo geral é verificar a influência do libertarismo no debate sobre a descriminalização do aborto voluntário, sendo os objetivos específicos: a) compreender o que é o libertarismo, suas premissas básicas e sua compreensão sobre a relação social do indivíduo e dele com o Estado; b) expor as principais ideias do libertarismo defendido por Robert Nozick; c) analisar a influência do pensamento libertarista nos argumentos que embasam a discussão do tema. Para tanto, utilizou-se do método hipotético-dedutivo, partindo-se da premissa de que o libertarismo influencia no debate a respeito da legalização do aborto voluntário pelo fato de defender a liberdade como direito individual absoluto. O estudo foi orientado por trabalhos desenvolvidos por autores e estudiosos do tema, utilizando-se uma abordagem qualitativa da pesquisa documental e bibliográfica realizada a partir de livros, artigos, dissertações publicadas em repositórios e decisões judiciais. Ao final, concluiu-se que, em certa medida, o libertarismo possui influência nos argumentos daqueles que defendem o aborto voluntário com base no direito à liberdade e autonomia da mulher.

Objetivo desse estudo foi identificar e descrever os principais sintomas apresentados pela Síndrome Pós-COVID-19.Trata-se de uma pesquisa descritiva, de Revisão Bibliográfica, dando prioridade às publicações no período de 2019 a 2022. As buscas das fontes foram realizadas por meio bases de dados, Scielo e Google acadêmico, visando a recuperação de artigos que foram selecionados por meio das seguintes palavras-chave: Fadiga muscular, cefaleia  e Covid-19. Os resultados encontrados apontam que os principais sintomas que permaneceram após a infecção pela covid-19, foram: fadiga, ageusia, anosmia e cefaleia. A fadiga apresentou uma maior incidência em pacientes que permaneceram em longos períodos sob tratamento em unidade de terapia intensiva. Em relação às alterações de olfatos e paladar, a colonização do vírus no sistema nasofaringe acaba acometendo suas funções devido a atividades de enzinas, que, posteriormente, tendem a adentrar ao Sistema Nervoso Central (SNC) gerando comprometimento em funções neurológicas e causando sinais e sintomas como a cefaleia, que também teve grande incidência no período pós-covid. Concluimos que os principais sintomas na Síndrome Pós-COVID-19 foram: fadiga muscular, cefaleia, perda do paladar e do olfato. Identificamos também que, após a fase aguda da doença, alguns pacientes  permaneceram com sintomas mais graves, sendo que estes tiveram maior comprometimento no sistema neurológico, cardiovascular, pulmonar e neurológico. Por se tratar de uma condição recentemente descoberta na visão científica, são necessários novos estudos sobre o tema, além do devido acompanhamento em relação às novas descobertas sobre a doença.

Cannabis linked to youth depression and suicide: AACAP
Authors: Knopf Alison
Published: January 2025

An article in Psychiatric News published last week summed up mounting evidence linking the use of cannabis by young people to depression and suicide. Quoting experts from the annual meeting of the American Academy of Child and Adolescent Psychiatry (AACAP), the article looks at the expanded types of products, increasing potency, and legalization are contributing to “unprecedented exposure to young people during a critical period of brain development,” said Jesse D. Hinckley, M.D., associate clinical professor of psychiatry and co‐founder of the addiction biology laboratory at the University of Colorado School of Medicine, at the meeting. “Cannabis prevention and early intervention are suicide prevention,” Hinckley said. “There's an even greater need for these programs in states that have passed recreational or medical cannabis laws, where youth cannabis use is more prevalent.”

Published: January 2025

Rare earth elements (REEs) are essential for many clean energy technologies. Yet, they are a limited resource currently obtained through carbon‐intensive mining. Here, bio‐scaffolded proteins serve as simple, effective materials for the recovery of REEs. Surface expression of the protein lanmodulin (LanM) on E. coli, followed by freeze‐drying of the microbes, yields a displayed protein material for REE recovery. Four REE cations (Y3+, La3+, Gd3+, and Tb3+) are captured efficiently, with over 80% recovery even in the presence of competitive ions at one‐hundred‐fold excess. Moreover, these materials are readily integrated into a filter with high capture capacity (12 mg g−1 dry cell weight) for the selective isolation and recovery of REEs from complex matrices. Further, the proteins in the filter remain stable over ten bind‐and‐release cycles and a week of storage. To improve the deployability of this filter material, a simple colorimetric assay with the dye alizarin‐3‐methyliminodiacetic acid is incorporated. The assay can be performed in under 5 min, enabling rapid monitoring of REE recovery and filter efficiency. Overall, this low‐cost, robust material will enable environmentally friendly recycling and recovery of critical elements.
Recreating Silk's Fibrillar Nanostructure by Spinning Solubilized, Undegummed Silk

Published: January 2025

The remarkable toughness (>70 MJ m−3) of silkworm silk is largely attributed to its hierarchically arranged nanofibrillar nanostructure. Recreating such tough fibers through artificial spinning is often challenging, in part because degummed, dissolved silk is drastically different to the unspun native feedstock found in the spinning gland. The present work demonstrates a method to dissolve silk without degumming to produce a solution containing undegraded fibroin and sericin. This solution exhibits liquid‐liquid phase separation above 10% (wt/wt), a behavior observed in the silk gland but not in degummed silk solutions to date. This partitioning enhances the stability of the undegummed solution, delaying gelation two‐fold compared with degummed silk at the same concentration. When spun under identical conditions, undegummed solutions produces fibers 8× stronger and 218× tougher than degummed silk feedstocks. Through ultrasonication, undegummed wet spun fibers are seen to possess hierarchical structure of densely packed ≈20 nm nanofibrils, similar to native silks, although completely absent from fibers wet‐spun from degummed silk solutions. This work demonstrates that the preservation of molecular weight, presence of sericin and stimulation of liquid‐liquid phase separation underpin a new pathway to recreate a hierarchical fiber with structures akin to native silk.
Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring
Authors: Shyam Sudip , Misra Sirshendu , Magdanz Veronika , Mitra Sushanta K
Published: January 2025

Conventional microscopy‐driven sperm health monitoring systems suffer from high infrastructural costs and complex protocols. Here, a simple, economical sperm motility assessment system is proposed. Based on a cantilever‐deflection‐based direct force measurement system capable of detecting wetting forces in the range of ≈µN, it is found that the adhesion of live and motile sperm cell‐laden droplets is dependent on sperm motility in the suspension. Further, it is observed that the sperm motility inside the droplet decreases with time, and the adhesion of the concerned droplet with a master substrate demonstrates an increasing trend. Contrary to an immotile cell, the motile sperm, due to its inherent nature of swimming parallel to the contact line, induces a lower restrictive force on the receding triple contact line of the droplet. The study establishes a potential avenue by which sperm cell motility can be predicted via measuring the adhesion of the sperm‐cell‐laden droplets with a standard surface using the simple and automatable cantilever‐deflection method. These findings can pave a pathway toward developing a user‐friendly, expertise‐independent diagnostic platform for in‐house sperm health monitoring.

Published: January 2025

Multiple resonance thermally activated delayed fluorescence (MR‐TADF) materials offer narrowband emission and efficiency but suffer from spectral broadening and aggregation‐caused quenching (ACQ) at high doped concentrations. In this study, two novel silicic linkage‐based dual‐core MR‐TADF emitters, DMeSiB and DPhSiB, are introduced, which effectively mitigate both concentration quenching and spectral broadening. DMeSiB and DPhSiB exhibit bluish‐green emission peaking at 493 and 495 nm with full‐width at half‐maximum (FWHM) values of 21 and 22 nm in toluene and high photoluminescence quantum yields exceeding 90% in doped films. At a doping concentration of 5 wt%, the organic light‐emitting diodes (OLEDs) based on DMeSiB and DPhSiB achieve maximum external quantum efficiencies (EQEmaxs) of 27.2% and 28.6% with narrow FWHMs of 25 and 24 nm, respectively. Over a doping concentration range of 5 wt% to 20 wt%, the OLEDs maintain high EQEmax values of 23.5%, 21.4%, 19.2% and 24.9%, 22.7%, 19.3%, respectively. Even at a 20 wt% doping concentration, the FWHMs of the devices broaden by only 2 or 3 nm, reaching 27 nm. This structural design facilitates efficient luminescence while successfully suppressing spectral broadening and ACQ, leading to improved device performance.

Published: January 2025

Lithium is becoming increasingly important due to its indispensable role in lithium‐ion batteries. The direct extraction of lithium from salt lakes, which are a main source of lithium, is challenging due to the coexistence of many interfering alkali and alkaline earth metals. In this work, we report that a synergistic solvent extraction (SSX) system containing 2,9‐dialkyl‐1,10‐phenanthroline and a hydrophobic anion ([NTf2]−) could extract lithium selectively with a high lithium loading capacity from solutions containing both alkali (sodium, potassium) and alkaline earth metals (magnesium, calcium), enabling the direct recovery of lithium from complex salt lakes. The outstanding lithium extraction performance of the SSX system is unprecedented, to the best knowledge of the authors. Through various characterizations and X‐ray diffraction of the complex crystals, the extraction mechanism has been revealed. This SSX system will potentially promote more efficient recovery of lithium from salt lakes.

Genetic causes of HCM are mostly related to sarcomeric genes abnormalities; however, syndromic, metabolic, and mitochondrial disorders play an important role in its etiopathogenesis in pediatric patients. We here describe a new case of apparently isolated HCM due to mitochondrial assembly factor gene NDUFAF1 biallelic variants (c.631C > T and an intragenic deletion encompassing exon 3, NM_016013.4). Alterations of this nuclear gene have been associated to Mitochondrial complex I deficiency, nuclear type 11 (OMIM *618234). We here report the fourth case of a child affected by complex I deficiency due to alterations in NDUFAF1 gene. His clinical features appear simpler when compared to the other cases described in the medical literature, increasing our knowledge regarding the highly heterogeneous clinical presentation associated with this disorder.

Published: January 2025

This paper is devoted to the event‐triggered fault‐tolerant bounded consensus tracking control for switched multi‐agent systems (MASs) with full‐state constraints and actuator faults. By using backstepping technology and fuzzy logic systems (FLSs), an event‐triggered fault‐tolerant control (FTC) scheme is constructed for switched MASs for the first time, which compensates the impact of actuator faults on the system and significantly reduces the updating frequency of controllers. The asynchronous switching error compensation functions are introduced into the designed controller and triggering mechanism, which solves the asynchronous switching problem prompted by the interaction of triggering and switching together effectively. In the meantime, the system states are restricted within the given sets under the barrier Lyapunov functions (BLFs). All the closed‐loop signals are bounded and the bounded consensus tracking control is realized with average dwell time (ADT). Finally, an example of chemical reactors is established for demonstrating the effectiveness of the developed scheme.

Published: January 2025

This paper focuses on the consensus problem for heterogeneous multi‐agent systems (HMASs) consisting of second‐order linear agents and nonlinear Euler–Lagrange (EL) agents. Firstly, the HMASs consensus control protocols are designed in the cases of leaderless and leader‐following, respectively. Among them, the research of these two parts is based on the undirected communication topology. Then, through the mathematical knowledge such as graph theory and Lasalle's invariance principle, the sufficient conditions of consensus are given, and the stability of the controller is further proved. At last, the validity of the above theory is proved by simulation results.
What Drives Carbon‐Reducing Investments? A Vignette Experiment on Managers' Decision‐Making From a Multilevel Perspective
Authors: Hahn Rüdiger , Pioch Thomas , Reimsbach Daniel , Schiemann Frank
Published: January 2025

Our study aims to shed light on the factors that drive managers' sustainability‐related decision‐making. We take a multilevel perspective, analyzing individual‐, organizational‐, and institutional‐level factors, which allows us to present a coherent account of a complex environment of influential factors. Based on an explorative vignette experiment with professional managers in a setting related to carbon‐reducing investments, we find that certain individual‐level factors, such as managers' biospheric orientation or a strong belief in business ethics, are associated with higher carbon‐reducing investments. However, these individual‐level factors do not alter the overall influence of organizational‐ and institutional‐level factors. The financial impact of carbon‐reducing investments—at the organizational level—as well as the number of carbon‐conscious investors and the regulatory disclosure regime in which a firm operates—at the institutional level—significantly drive managers' investment decisions. We find only a few instances in which specific factor combinations are decision‐relevant. These findings have important implications for research and policymaking with regard to improving corporate sustainability in general and particularly reducing corporate carbon emissions.
ESG Implementations, Green Process Innovation, and Social Performance in Vietnamese Manufacturing Firms: Proactive Environmental Strategy and Green Absorptive Capacity as Moderators
Authors: Van Hien Vo , Abu Afifa Malik , Van Bui Duong
Published: January 2025

This study evaluates the direct and indirect effects of the environmental, social, and governance (ESG) implementations on green process innovation (GPCI) and social performance (SCP) in Vietnamese manufacturing firms, respectively. Exploring the moderating role of proactive environmental strategy (PES) and green absorptive capacity (GAC) on the impact of ESG implementations on GPCI are the next objectives. These investigations are supported by the legitimacy theory and dynamic capability theory. Through the survey method, data collected from 205 managers' responses were analyzed by partial least squares structural equation modeling. The results show important contributions. First, ESG implementations have a positive role in GPCI. Second, GPCI is the driving force behind SCP. Third, ESG implementations have an indirect influence on SCP through GPCI. Fourth, the impact of ESG implementations on GPCI is positively moderated by GAC and PES. Further analysis shows that three‐way interaction (ESG implementations × PES × GAC) enhances GPCI. Therefore, the above results fully support legitimacy theory and dynamic capability theory, and thus they provide highly theoretical contributions and managerial implications.
From subsidies to stressors: Positively skewed ecological gradients alter biological responses to nutrients in streams

Published: January 2025

Subsidy–stress gradients offer a useful framework for understanding ecological responses to perturbation and may help inform ecological metrics in highly modified systems. Historic, region‐wide shifts from bottomland hardwood forest to row crop agriculture can cause positively skewed impact gradients in alluvial plain ecoregions, resulting in tolerant organisms that typically exhibit a subsidy response (increased abundance in response to environmental stressors) shifting to a stress response (declining abundance at higher concentrations). As a result, observed biological tolerance in modified ecosystems may differ from less modified regions, creating significant challenges for detecting biological responses to restoration efforts. Using the agriculturally dominated Mississippi Alluvial Plain (MAP) ecoregion in Mississippi, USA, as a case study, we tested the hypothesis that macroinvertebrate taxa that typically display a subsidy response to nutrient enrichment in less modified ecoregions (i.e., nutrient‐tolerance) shift to a stress response to increasing nutrients in highly modified watersheds with elevated baseline nutrient conditions (i.e., nutrient intolerance). The abundance and diversity of MAP‐specific intolerant taxa identified with threshold indicator taxa analysis were either unresponsive or exhibited a subsidy response to increasing nutrients in less modified ecoregions in Mississippi with less land alteration and lower nutrient concentrations, but declined at higher concentrations, providing evidence for a stress response to elevated nutrients in the MAP. Additionally, MAP‐specific tolerant and intolerant taxa richness responded to increased nutrients predictably and consistently across space and time within the MAP. However, in MAP streams, elevated specific conductance was predicted to dampen the response of tolerant and intolerant taxa richness to increasing nutrient concentrations, highlighting the importance of considering multistressor interactions when interpreting biological data. Lastly, we demonstrate the efficacy of this approach with sediment bacterial communities characterized with amplicon sequencing, which lack sufficient life history characteristics necessary for the development of multimetric indices. Both macroinvertebrate and bacterial communities responded similarly to increasing nutrient concentrations, suggesting DNA‐based approaches may provide an efficient biological assessment tool for monitoring water quality improvements in highly modified watersheds.

Published: January 2025

A thermal‐energy‐storage (TES) system is investigated in this work. The charging process uses hot air passed through a fixed bed, transferring thermal energy to solid particles, while discharging occurs with cold air flowing in the opposite direction. A novel automated dynamic simulation model of the TES is developed and validated using data from the literature. This study uniquely operates with a heat‐transfer‐fluid (HTF) temperature of up to 1200 °C during charging, with discharge temperatures regulated via a bypass controller. Simulations explore the fixed‐bed storage behaviour during charging/discharging cycles, with 64 parameter variations tested. In addition to air, CO2 is evaluated as an HTF to enhance performance due to its higher density. Results show that Case C14 (using air) achieves a maximum thermal capacity of 3.237 MWh and utilization of 55.4%. When CO2 is substituted for air under the same parameters, a thermal capacity and utilization increase of 4.5% is observed, along with reduced compressor work, highlighting CO2's advantages for improved efficiency.

Intervertebral disc degeneration (IVDD) is a chronic musculoskeletal disorder causing lower back pain, imposing a considerable burden on global health. Hyperglycemia resulting from diabetes mellitus induces advanced glycation end products (AGEs) accumulation in nucleus pulposus cells, leading to IVDD. Mitigating AGEs accumulation is a novel promising strategy for IVDD management. In our study, palladium nanoparticles (Pd NPs) preferentially colocalized within the endoplasmic reticulum and efficiently degraded AGEs via valosin‐containing protein (VCP)‐mediated autophagy pathways. Pd NPs promoted the ATPase activity of VCPs, upregulated microtubule‐associated proteins 1A/1B light chain 3 (LC3) expression, and increased AGEs‐degrading autophagosome production. They ameliorated mitochondrial function, relieved endoplasmic reticulum stress, and counteracted the detrimental oxidative stress microenvironment in a high‐glucose/high‐fat‐induced nucleus pulposus cell degeneration model. Consequently, Pd NPs effectively rescued nucleus pulposus cell degeneration in vitro, restored disc height and partially recovered the degenerated phenotype of IVDD in vivo. We provide novel insights regarding IVDD management by targeting AGEs degradation, showing potential for clinical practice.

Published: January 2025

Background

Oral lichen planus (OLP) and oral lichenoid lesions (OLL) are common chronic inflammatory diseases associated with malignant transformation. Risk factors associated with malignant transformation of OLP and OLL are not well defined.

Methods

A retrospective chart review assessed risk factors for progression of OLP and OLL to oral epithelial dysplasia (OED) or oral squamous cell carcinoma (OSCC) at a tertiary care centre in Toronto, Canada.

Results

Five‐hundred‐fifty‐five patients identified with biopsy proven OLP or OLL met the inclusion criteria. In total, 3.2% (n = 18) progressed to OED (1.8%, n = 10) or OSCC (1.4%, n = 8). Risk factors associated with transformation included the plaque‐like subtype (OR = 40.33, p < 0.001) and lesions located on the tongue (OR = 6.81, p = 0.008).

Conclusions

Clinical examination to identify lesion subtype and location provides useful indicators for risk of progression in patients with OLL and OLP.
