Research on the Cultivation of College Students’ National Spirit from the Perspective of the Chinese Dream
Authors: Li Zhenyuan
Published: February 2023

Chinese college students are the future of the vigorous development of the motherland, the expectation of the Chinese nation, the successors and builders of the domestic socialist modernization cause, and the main bearers and practitioners of the Chinese dream. The cultivation of college students’ own national cultural spirit is not only related to the overall development of individuals, but also closely related to the future prospects of our country and the survival and development of the entire ethnic minority. Therefore, the cultivation of the national cultural spirit of our college students in the perspective of the Chinese Dream can improve the majority of college students’ sense of identity with the Chinese national culture, adhere to the Marxist ideal, unswervingly take the correct confidence of the socialist line with Chinese characteristics, and actively participate in the grand practice of achieving the Chinese Dream, thus serving as the backbone of the implementation of the Chinese Dream.
Hipótesis etimológica de kuña ‘mujer’ a partir de un estudio comparado en las lenguas tupí-guaraníes
Authors: Aguilera Jiménez Domingo Adolfo
Published: February 2023

Este artículo presenta un estudio etimológico de la palabra kuña ‘mujer’ en las lenguas tupí-guaraníes, habladas por varios millones de personas en Paraguay y otros países vecinos. A través de un estudio morfológico y semántico comparado del vocablo en 27 lenguas actuales de la familia Tupí-Guaraní, además de una pesquisa en la documentación histórica de obras antiguas clásicas, se sugiere la hipótesis de que kuña ‘mujer’ etimológicamente puede traducirse como ‘dueña o señora de la cosecha’, ‘guardiana, ama o espíritu de la roza’, ‘dueña del sustento’, entre otras posibilidades. Un acercamiento a la concepción de la mujer desde las culturas indígenas puede sumar un punto de reflexión desde la alteridad, en una materia muy sensible de nuestro tiempo: la construcción de la igualdad de derechos entre hombre y mujer y el cese de toda violencia hacia las mujeres en el mundo.
Arte rupestre y sondeos arqueológicos en El Salvador: Resultados e Interpretaciones
Authors: Costa Philippe
Published: February 2023

El estudio del arte rupestre, donde sea que se realice, implica varias problemáticas de las cuales la cronología es una de las más delicadas. Hasta ahora, los métodos para producir fechamientos directos conciernen los yacimientos con pinturas donde la las dataciones radiocarbónicas pueden establecerse directamente sobre el material pictórico. En el caso de los grabados, los fechamientos resultan más delicados; a parte del estudio iconográfico que puede permitir relacionar motivos con periodos cronológicos, otra posibilidad es llevar a cabo sondeos arqueológicos al pie de las manifestaciones rupestres. En este caso, el objetivo es encontrar artefactos, en particular material cerámico o lítico, más conocido y fácil de fechar por los arqueólogos. Se trata allí de una propuesta cronológica ya que el posible material evidenciado solo puede relacionarse de forma indirecta con la producción rupestre. En El Salvador, el autor propuso un estudio de los yacimientos rupestres dentro de una perspectiva más regional, en un marco de estudio que abarca el este de Guatemala y el centro de Honduras. Por primera vez, se trató de aportar una investigación específica sobre el arte rupestre a una escala amplia. Los esfuerzos para aportar datos respecto a la cronología de los sitios se tradujeron por la realización de sondeos arqueológicos en 11 yacimientos rupestres diseminados sobre todo el territorio del país. Aunque no todos evidenciaron material, los descubrimientos permitieron adelantar propuestas cronológicas para algunos sitios, y asimismo relacionar periodos con tradiciones rupestres.

Published: February 2023

Diversos trabajos sugieren una tendencia hacia la disminución en la estatura adulta conforme aumenta la dependencia de la agricultura en las distintas poblaciones humanas. En este trabajo analizamos los patrones de variación de la estatura humana adulta en poblaciones que habitaron la Cuenca de México desde épocas tempranas. Hemos implementado el análisis de normalidad de la varianza (ANOVA) y el modelo Relethford-Blangero y nuestros resultados, con base al análisis de 532 esqueletos de sujetos adultos, (43.7% femeninos y 56.3% masculinos), muestran una tendencia secular negativa, disminuyendo la talla hasta en tres centímetros en las etapas tardías. Nosotros discutimos los resultados, con respecto al efecto que pudieron tener los reacomodos demográficos y la canalización del desarrollo en la tendencia de cambio de la estatura en la Cuenca de México en la transición del Clásico al Postclásico.

Published: February 2023

Abstract: The analysis of Pre cast box is done by using STAAD Pro. And design of Thrust bed is done by Limit state method manually. Box pushing is pushing a large precast reinforced concrete box horizontally through the ground, usually beneath a road or railroad that must not be interrupted. The major advantage of the process is its essential simplicity. The structure is built away from the roadway, in the clear, without the constraints of shoring and traffic controls. When the structure is ready, a shield is fitted to the front, hydraulic jacks are installed behind, and the box is pushed into final position while simultaneously the earth is excavated from within. The pushing of box generally takes only a few days to a week. During that time, traffic is proceeding overhead normally, unaware of the construction below. The nondisruptive nature of the process together with its inherent safety, simplicity and economy make box pushing a useful tool for the practicing civil engineer. This paper intends to bring a greater familiarity with the box pushing process to the reader and then give some considerations and guidelines to assist engineers in designing a project that can be built using the box pushing method. Box pushing is a well- established means of engineering culverts or tunnels under rail embankments or waterways to accommodate road or rail traffic.

Biomass waste potential from tea pruning was high, however the utilization of the waste still low. Forming pellet from the waste was one of means for utilizing it to have value-added. Pelletization is a process of compressing the material to increase density value, calorific  value, and to uniform the particle size. The method in tea pruning waste pelletization used because the waste is consists of dry twigs and leaves so it was easier in reducing the particle size as pellet raw material. This research purpose was to identify the wood pellet characteristics of various particle size from tea pruning waste, consisted of water content, ash content, and wood pellet density against calorific  value produce. The material used in this research was tea pruning waste available all years in the experimental plantation of Reserach Institute for Tea and Cinchona Gambung that has been dried for three days.  Pelletization process starts with reducing the tea pruning waste particle using Chopper machine to acquire dust particles. Afterward, those dust was separated into three treatments, which are, passed sieve number 7 mesh, 14 mesh, and 18 mesh. Calorific  value produced from the wood pellet was the main factor from all pelletization process, the result show that the dust passed sieve number 18, which is the smallest particle size, has the highest calorific y value produced in the amount of 4.431 cal/g

The tea production and the quality were over the years, especially in West Java, Indonesia. This had been affected by several factors including the aged of tea plantations, declining soil fertility, and soil degradation among other factors. Andisol is the most suitable soil and dominant in Indonesia for tea plantation. The objectives of this study were to evaluate the impact of long-term tea cultivation on soil organic matter degradation in 6 years (2011 and 2017) in tea plantations in Bandung, Bogor, Cianjur and Garut, West Java. Data analysis used the independent sample t-test with SPSS 16.0 at a significant level of 95%. This study used a quantitative descriptive method by comparing the levels of organic matter and macronutrients from 89 samples taken in 2011 and 2017. Soil samples were taken at a depth of 35-40 cm with a distance of 25cm of the tea plant. Conclusion of the study, that the levels of organic matter in the regions of Bandung, Cianjur, and Garut are not significantly different between 2011 and 2017; while in the Bogor area the level of organic matter in 2011 was 5.41% and decreased in 2017 was 4.40% (a decrease of 18.72%). However, based on C-organic data in 2011 and 2017 nutrient degradation has occurred in all locations. Decreasing organic matter can cause a low decrease in soil fertility and productivity of tea crops. Provision of organic matter and proper fertilization must be done to maintain soil fertility and productivity of tea plants.

The utilization of tea area especially on young tea period to intercropping was one of the efforts to keep the income stability, especially on tea smallholder plantation scale. Chilli was one of the plants planted on the tea area by the intercropping system. But, chili has different habitat and characteristics than tea, especially on soil pH characteristics. The optimum pH to the growth of Chili on 6–7, otherwise tea on 4,5–5,6. Generally, chili needs dolomite around 3,66–6,83 tones per hectare if the difference of pH around 1,0–2,0. The research aimed to evaluate the soil pH and exchangeable-Ca (Ca-dd) on Monoculture and Intercropping tea with chili on the selected slope of the area. The experiment was conducted at the Experimental Garden of Research Institute for Tea and Cinchona, West Java, on the young tea area age two years. The Split Split Plot experimental design was used with three repetitions. As Main Plot was Planting System (Intercropping and Monoculture System); while the sample position (between plant and row of the plant) was as Sub Plot and Sub Sub Plot was Land Slope (8-15%, 16-25%, dan >25%). The result shows that the intercropping system tea with chili caused the Ca-dd and soil pH higher compared to that monoculture system. But, the land slope was not significantly influencing the Ca-dd and soil pH. The highest Ca-dd was on the row of the plant with Intercropping system on slope 16-25% treatment amount 8,82 m.e/100 g soil and it had a correlation also to the highest pH i.e 5,43. If the intercropping system still used chicken manure as a fertilizer, it will be caused by the tea plant was calcium poisoning.

Published: February 2023

Semakin intensifnya kegiatan budidaya di perkebunan teh, akan berpotensi terjadinya penurunan kesuburan tanah khususnya pada areal pertanaman teh setelah dipangkas. Areal setelah dipangkas mempunyai permukaan lahan yang terbuka dan berpengaruh terhadap penurunan produktivitas lahan. Oleh karena itu, pengolahan tanah setelah pangkas dengan garpu tanah dan pemberian asam humat ekstrak rumput laut dilakukan untuk meningkatkan kesuburan tanah. Tujuan penelitian ini untuk mengetahui pengaruh pengolahan tanah dan aplikasi asam humat terhadap pertumbuhan tunas dan produksi jendangan setelah pangkasan. Penelitian ini dilaksanakan pada Januari sampai Juli 2017 di Kebun Percobaan Pusat Penelitian Teh dan Kina (PPTK) pada areal tanaman teh produktif klon GMB7 setelah dipangkas. Penelitian menggunakan rancangan acak kelompok dengan 2 faktor perlakuan dan 3 kali ulangan. Faktor pertama adalah perlakuan pengolahan tanah (kontrol, garpu rengat dan garpu balik); faktor kedua adalah pemberian asam humat (dosis per ha 4 l/ha, dosis 6 l/ha dan dosis 8 l/ha dengan volume semprot 200 l/ha). Parameter pengamatan terdiri dari kadar pati kualitatif; jumlah tunas per plot; produksi jendangan per plot (kg) dan intensitas cahaya di bawah tajuk. Hasil penelitian diperoleh bahwa penggarpuan tanah dan pemberian asam humat belum memberikan pengaruh signifikan terhadap peningkatan jumlah tunas dan produksi pucuk segar jendangan sampai 4 bulan setelah pangkas, namun pemberian asam humat dosis 8 l/ha menunjukkan kecenderungan peningkatan produksi segar setelah pangkas.

Published: February 2023

We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays the role of a number-phase uncertainty for spin systems. It is important that the relation is given with well-defined and easily measurable quantities, and that it does not need assuming infinite dimensional systems. Based on this uncertainty relation, we show how to detect bipartite entanglement in an unpolarized Dicke state of many spin-1/2 particles. The particles are split into two subensembles, then collective angular momentum measurements are carried out locally on the two parts. First, we present a bipartite Einstein-Podolsky-Rosen (EPR) steering criterion. Then, we present an entanglement condition that can detect bipartite entanglement in such systems. We demonstrate the utility of the criteria by applying them to a recent experiment given in K. Lange et al. [Science 360, 416 (2018)] realizing a Dicke state in a Bose-Einstein condensate of cold atoms, in which the two subensembles were spatially separated from each other. Our methods also work well if split spin-squeezed states are considered. We show in a comprehensive way how to handle experimental imperfections, such as the nonzero particle number variance including the partition noise, and the fact that, while ideally BECs occupy a single spatial mode, in practice the population of other spatial modes cannot be fully suppressed.

Published: February 2023

A quantum internet aims at harnessing networked quantum technologies, namely by distributing bipartite entanglement between distant nodes. However, multipartite entanglement between the nodes may empower the quantum internet for additional or better applications for communications, sensing, and computation. In this work, we present an algorithm for generating multipartite entanglement between different nodes of a quantum network with noisy quantum repeaters and imperfect quantum memories, where the links are entangled pairs. Our algorithm is optimal for GHZ states with 3 qubits, maximising simultaneously the final state fidelity and the rate of entanglement distribution. Furthermore, we determine the conditions yielding this simultaneous optimality for GHZ states with a higher number of qubits, and for other types of multipartite entanglement. Our algorithm is general also in the sense that it can optimise simultaneously arbitrary parameters. This work opens the way to optimally generate multipartite quantum correlations over noisy quantum networks, an important resource for distributed quantum technologies.

Published: February 2023

As the width and depth of quantum circuits implemented by state-of-the-art quantum processors rapidly increase, circuit analysis and assessment via classical simulation are becoming unfeasible. It is crucial, therefore, to develop new methods to identify significant error sources in large and complex quantum circuits. In this work, we present a technique that pinpoints the sections of a quantum circuit that affect the circuit output the most and thus helps to identify the most significant sources of error. The technique requires no classical verification of the circuit output and is thus a scalable tool for debugging large quantum programs in the form of circuits. We demonstrate the practicality and efficacy of the proposed technique by applying it to example algorithmic circuits implemented on IBM quantum machines.

The role of the aircraft maintenance industry as an aircraft maintenance service which is expected to be able to maintain the survival of the aircraft itself. For example, PT GMF Aero Asia is one of the Strategic Business Units (SBU) owned by PT Garuda Indonesia which is specialized in aircraft maintenance, repair and overhaul services which include aircraft frames, engines, components and their support. In this study, a quantitative assessment of the availability and capability of maintenance facilities was carried out using a preventive maintenance method with a dynamic system model approach that describes the level of availability and maintenance capability of aircraft batteries. Calculations have been made with a computer program, POWERSIM, in actual conditions that in December 2020 the total number of batteries in maintenance was 102 batteries for Airbus types and 80 batteries for Airbus types. With the assumption that starting in 2021 there will be an increase in the number of aircraft by 1 (one) unit per month, then at the end of the study period until July 2021 the calculation of the utility factor will be as follows, the total utility factor for Boeing is still below 1, while for Airbus starting April 2021 the utility factor is above 1. So that the operator's ability to handle Airbus type battery maintenance is not sufficient. For this purpose, an alternative scenario needs to be created, namely scenario 1 by adding one operator per shift and scenario 2 by increasing the operator's workload in handling the number of batteries handled to as many as 6 battery units. The results of the calculation of the utility factor show that in both conditions the scenario gives a value below 1. The best choice in terms of simplicity in handling the number of operators, then the choice of condition scenario 2 is the best choice.

Authors: Ngoc Hoa Le , Minh Lu Hung
Published: February 2023

The advancement of Information Communication and Technology (ICT) offers enormous opportunities to enhance the efficacy of learning process in all levels of education, including Early Childhood Education (ECE). However, in the light of the recent years, there have not been some concern about the issue of use of technology to assist ECE process in the context of Vietnam. Thus, this study explores Vietnamese early childhood teachers’ beliefs and practices about the use of technology to facilitate storytelling for pre-school children. A web-based survey research was adopted to scrutinize the beliefs and practices of 228 ECE teachers about digital storytelling in Can Tho Vietnam. The results demonstrated that these teachers hold high levels of beliefs that digital storytelling could be used to enhance learning. In addition, they had carried out digital storytelling activities in their learning practices. The results emphasized that several concerns must be taken by teachers, parents, and related stakeholders in using technological tools in young children’s learning environment. This study offers pedagogical insights for ECE teachers to integrate digital storytelling in their learning activities. In short, the use of technology for pre-school children can provide a lot of benefits if it is skillfully executed by both teachers and parents.

Immune-related genes (IRGs) affect the composition and abundance of
tumor-infiltrating immune cells (TIICs) by encoding immune molecules.
The utilization of IRGs and TIICs offers considerable potential for
immunotherapy studies of breast cancer. In this study, the
differentially expressed genes (DEGs) between breast cancer patients and
healthy individuals were assessed using the Cancer Genome Atlas (TCGA).
ImmPort and TISIDB databases, the Weighted Gene Co-Expression Network
Analysis (WGCNA), univariate Cox regression and LASSO penalized Cox
regression methods were used to calculate the composition and abundance
of immune cell types. It was found that CD79A and GZMAcould
independently predict the prognosis of breast cancer and were
significantly associated with activated CD8 T cells, immature B cells,
folic helper T cells and regulatory T cells, implying that these two
genes are involved in the immune regulation and progression of breast
cancer and could potentially be new targets for breast cancer
immunotherapy.

the literature. In the present case, we report a patient who presented
with tamponade physiology during COVID-19 and developed
pneumopericardium after emergency pericardiocentesis. Immediate
recognition and treatment are crucial and chest X-ray, thorax
computerized tomography and transthoracic echocardiography are used for
diagnosis.
vAMPirus: A versatile amplicon processing and analysis program for studying viruses
Authors: Veglia Alex , Rivera-Vicens Ramon E , Grupstra Carsten , Howe-Kerr Lauren , Correa Adrienne
Published: February 2023

Amplicon sequencing is an effective and increasingly applied method for
studying viral communities in the environment. Here, we present
vAMPirus, a user-friendly, comprehensive, and versatile DNA and RNA
virus amplicon sequence analysis program, designed to support
investigators in exploring virus amplicon sequencing data and running
informed, reproducible analyses. vAMPirus intakes raw virus amplicon
libraries and, by default, performs nucleotide- and protein-based
analyses to produce results such as sequence abundance information,
taxonomic classifications, phylogenies, and community diversity metrics.
The vAMPirus pipelines additionally include optional approaches that can
increase the biological signal-to-noise ratio in results by leveraging
tools not yet commonly applied to virus amplicon data analyses. In this
paper, we validate the vAMPirus analytical framework and illustrate its
implementation into the general virus amplicon sequencing workflow by
recapitulating findings from two previously published double-stranded
DNA virus datasets. As a case study, we also apply the program to
explore the diversity and distribution of a coral reef-associated RNA
virus. vAMPirus is incorporated with the Nextflow workflow manager,
offering straightforward scalability, standardization, and communication
of virus lineage-specific analyses. The vAMPirus framework itself is
also designed to be adaptable; community-driven analytical standards
will continue to be incorporated as the field advances. vAMPirus
supports researchers in revealing patterns of virus diversity and
population dynamics in nature, while promoting study reproducibility and
comparability.
Multisensory integration by polymodal sensory neurons dictates larval settlement in a brainless cnidarian larva
Authors: Birch Sydney , Plachetzki David
Published: February 2023

Multisensory integration (MSI) combines information from more than one
sensory modality to elicit behaviors distinct from unisensory behaviors.
MSI is best understood in animals with complex brains and specialized
centers for parsing sensory information, but the dispersive larvae of
sessile marine invertebrates utilize multimodal environmental sensory
stimuli to base irreversible settlement decisions on, and most lack
complex brains. Here, we examined the sensory determinants of settlement
in actinula larvae of the hydrozoan Ectopleura crocea (Cnidaria),
which possess a diffuse nerve net. A factorial settlement study revealed
that photo-, chemo-, and mechano-sensory cues each influence the
settlement response, which was complex and dependent on specific
combinations of cues, therefore indicating MSI. Mechanosensory cues
either inhibited or enhanced settlement rates depending on the presence
or absence of chemical and light cues in the environment. Sensory gene
expression over development peaked with developmental competence to
settle, which in actinulae, requires cnidocyte discharge. Transcriptome
analyses also highlighted several deep homological links between
cnidarian and bilaterian mechano- chemo- and photo-sensory pathways.
Fluorescent in situ hybridization studies of candidate transcripts
suggested cellular partitioning of sensory function among the few cell
types that comprise the actinula nervous system, where ubiquitous
polymodal sensory neurons with putative chemo- and photo-sensitivity
interface with mechanoreceptive cnidocytes. We propose that a simple
multisensory processing circuit, involving polymodal chemo/photosensory
neurons and mechanoreceptive cnidocytes, is sufficient to explain MSI in
actinulae settlement. Our study demonstrates that MSI is not exclusive
to complex brains, but likely predated and contextualized their
evolution.
Highly conserved synteny despite massive chromosome fusion and fission suggest fragile sites in holocentric plants
Authors: Escudero Marcial , Marques André , Lucek Kay , Hipp Andrew
Published: February 2023

Holocentric organisms, unlike typical monocentric organisms, have
kinetochore activity distributed along almost the whole length of the
chromosome. Because of this, chromosomal rearrangements through fission
and fusion are more likely to become fixed in holocentric species, which
may account for their extraordinary rates of chromosome evolution.
Genome synteny has been reported to be conserved in animals with
holocentric chromosomes despite high rates of chromosome rearrangements.
Comparing genomes of Carex species and a genome of a distantly related
Cyperaceae we have characterised conserved vs. rearranged genome regions
across pairs of species that range in time since divergence between 2
and 50 million years. We have compared a C. scoparia genome with a
linkage map of the same species to study rearrangements at a population
level and suppression of recombination patterns. We found a surprisingly
conserved genome synteny even between very distantly related species and
extraordinarily high rates of chromosome evolution in genus Carex.
Comparing the distribution of repetitive DNA and gene density between
conserved and rearranged genomic regions, we found repetitive DNA to be
related to holocentromeres and as well as rearranged regions of the
genome. This evidence of extremely conserved synteny in sedges and the
massive events of chromosome fission and fusion found across the
evolution of genus Carex suggests the presence of common genomic
hotspots of chromosome evolution related to repetitive DNA.

The present work focusses on the control of marijuana in the
population. This real-world problem is shaped in the language of
mathematics and hence a mathematical model for the control of marijuana
is formulated. The total population of the people is divided into two
classes, the marijuana users, and the non-users. The users are further
divided in four sub-classes, each sub-class represents a stage/level of
addiction to the drug. The reproduction number ( R 0 ) of
marijuana usage is found from the proposed mathematical model. The
sensitivity analysis reveals the importance of many parameters in the
further spreading of marijuana is found out. Based on the sensitivity
analysis, the parameters that plays a significant role in marijuana
transmission were found. Furthermore, strategies were formulated to
prevent the marijuana transmission in the population. Numerical
simulations were also carried out to determine how the control
strategies will perform.
Population Structure of the sea urchin (Εchinometra lucunter lucunter) in the Caribbean Sea: Do Marine Discontinuities influence connectivity?
Authors: Benavides-Serrato Milena , Barrios Lina , Campos Nestor Campos , Preziosi Richard
Published: February 2023

Efforts to define the marine connectivity among populations have been
focused overwhelmingly on corals, sponges and fish populations, but are
lacking in other well represented marine taxa. The sea urchin
Echinometra lucunter lucunter was selected due to its wide
distribution throughout the Caribbean Sea and its biological and
ecological characteristics. The aim of this research was to postulate
genetic connections between populations of Echinometra lucunter
lucunter throughout the Caribbean Sea to detect whether the marine
discontinuities identified for other taxa affect their connectivity, a
critical issue for future conservation and management. Specific
microsatellites were used to detect the genetic structure of E.
lucunter lucunter through the region. The results showed clear evidence
of genetic structure and gene flow through the Caribbean region, with
three genetic populations from the south-west to the north-east: first
the Colombian Caribbean Sea, a second population related to Venezuela
and Belize, and a third group defined for Puerto Rico in the North-East.
The evidence of structure and gene flow between the populations of
E. lucunter lucunter is related to marine discontinuities such as
the influence of physical factors (continental margin, Caribbean
currents, calcareous rock as the main substrate, riverine discharges)
and their variation through the area, as well the biological
characteristics of the specie (e.g., assortative mating through gamete
recognition, stochastic reproduction, patchy gamete distribution). These
results will facilitate their conservation efforts in the area and offer
important key data for the application of conservation and management
strategies of Marine Protected Areas
ALCAPA syndrome: an unexpected cause of severe mitral regurgitation in an adult
Authors: J Largo , K Garcia , P Lopez , A Figueredo , M Ocampo , LE Echeverría
Published: February 2023

Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a
rare congenital anomaly that usually manifests in childhood and has a
high mortality rate in the first year of life if not corrected. We
present the case of a middle-aged woman who presented with exertional
dyspnea and severe ischemic mitral regurgitation; further imaging
revealed it was secondary to ALCAPA. The patient was referred for
valvular reconstruction and surgical revascularization with left
coronary artery reimplantation in the aorta. The patient had an adequate
postoperative result and symptomatic improvement during follow-up.
Although ALCAPA is a rare cause of mitral regurgitation in adults, its
pathophysiology is like that of ischemic origin from atherosclerotic
coronary disease, and its treatment is therefore similar to obtain
adequate clinical improvement.

Published: February 2023

Vascular network labeling in transparent tissues provides more complete
information on blood vessels. To achieve a fast and efficient method for
vascular network labeling in transparent tissues, we compared various
vascular labeling methods under different tissue clearing protocols.
FITC-dextran labeling and CUBIC cleaning treatment were found to be the
best options for vascular network labeling in cleared mouse tissues.
Satisfactory labeling of vascular networks in various organs can be
achieved by selecting FITC-dextran with different molecular weights and
different administration methods.
