BACKGROUND

Digital mental health interventions (DMHIs) have the potential to increase mental health support among isolated older adults. However, the older adult population can experience several barriers to accessing and using digital health resources, and may need extra support to experience its benefits.

OBJECTIVE

This paper aimed to understand what older adults consider important aspects of support when engaging in a digital mental health program. The program entailed 3 months of staff support to take part in digital literacy training and engage with the online mental health platform myStrength.

METHODS

Thirty older adults took part in a digital mental health program provided by county mental health services. Participants attended 4 classes of digital literacy training, had access to the online mental health platform myStrength for 2 months with staff support (and 10 months after the program without support), and received support from program staff during the entire 3-month program.

RESULTS

Participants valued ongoing support in three main areas: technical support to assist them in using technology, guided support to remind them to use myStrength and practice skills they had learned, and social support to enable them to connect with others through the program. Furthermore, participants reported that social connections were the most important aspect of the program, that they were mainly motivated to take part in the program because it was recommended to them by trusted others such as a community partner, and/or because they believed it could potentially help others.

CONCLUSIONS

Our findings can be used to inform the design of future digital mental health programs for older adults, who may have unique support needs.

Evaluation the Mechanical Properties of Kaolin Particulate Reinforced Epoxy Composites
Authors: Mohmmed Jabbar Hussein
Published: October 2022

Epoxy resin has many chemical features and mechanical properties, but it has a small elongation at break, low impact strength and crack propagation resistance, i.e. it exhibits a brittle behavior. In the current study, the influence of adding kaolin with variable particle size on the mechanical properties (flexural modulus E, toughness Gc, fracture toughness Kc, hardness HB, and Wear rate WR) of epoxy resin was evaluated. Composites of epoxy with varying concentrations (0, 10, 20, 30, 40 weights %) of kaolin were prepared by hand-out method. The composites showed improved (E, Gc, Kc, HB, and WR) properties with the addition of filler. Also, similar results were observed with the decrease in particle size. In addition, in this study, multiple regression models were developed by utilizing (SPSS) package to predict the properties of kaolin reinforced epoxy composites. Good agreement was obtained between the predicted and the experimental results. The accuracy of prediction was (89.71%, 80.58%, 85.82%, 92.27%, and 94.49%) for E, Gc, Kc, HB, and WR, respectively.

Published: October 2022

This paper presents a multidimensional methodology for assessing the scientific, social, economic, political and environmental impacts of citizens science (CS) projects. Besides these five areas of impact, the methodology considers also the transformative potential of the CS projects, i.e. the degree to which a CS project can help to change, alter, or replace current systems, the business-as-usual, in one or more fields such as science production or environmental protection. The methodology is designed to be modular and flexible so to adapt to the specificities of different CS projects and offers operational tools for its use by non-experts. The paper also describes the co-design process followed for its development and discusses the main lessons learned as emerged during its testing with 16 citizen science projects.

Authors: M Tejas Kumar , D Rakesh M
Published: October 2022

Abstract: The need to find new antibiotics is expanding as a result of the quick rise in bacteria that are resistant to medicines. Discovering drug-protein interactions could be an essential first step in the process of developing drugs since it will substantially reduce the scope of the look for possible solutions. Since in vitro assays are extremely time-consuming and pricey. We developed a machine learning method that can predict medications for the target in order to overcome this difficulty. We used the Padel script to do predictions on several chemical libraries, acquire drug physical and chemical properties, and obtain features extracted. establishing which model is best for predicting drug-target interactions is performed by analyzing the Random Forest technique with the Naive Bayes method, K-Nearest Neighbor, and other choices. This study reduces the failure rates and costs incurred when creating new pharmaceuticals while demonstrating the value of adopting machine learning approaches in drug discovery.

Estimation of Fatigue and Rutting Life Using Falling Weight Deflectometer of Flexible Pavement Road in Hilly Terrain
Authors: Sharma Gagan , Chaudhary Harivansh Kumar , Malik Akash
Published: October 2022

Abstract: Establishing the qualities of the pavement material and its structural capability is the most important step in establishing effective pavement maintenance and management techniques. This can be done by looking at how the pavement reacts to the applied load. The Falling Weight Deflectometer (FWD) is used in this study to assess the performance of a road stretch of the Federal Route in the State of Uttarakhand by measuring deflection in response to the weight applied at various sites along the highway. FWD is used to assess the pavement's response to a static load. Using the obtained deflection data, the KGPBACK is used to back-calculate the simulated layers of the pavement. Data is gathered then integrated into the IITPAVE software to create a pavement overlaying design. Flexible pavement is modelled as an elastic multilayer structure to see how bituminous overlay maintenance affected the distress models, and all 4 distress (cracking, rutting, rut depth, and roughness) are shown to be reduced. As a result, the research article provides a methodology that administrators can use to anticipate when and how much financing is needed to preserve and maintain the Indian Highway Road network.

This article has main points of discussion on issues related to how political survey institutions should operate to support democracy in Indonesia. The purpose of the study in this article is to map the ideal operational pattern of political survey institutions to support democracy in Indonesia. By using the literature study method, this article collects various literature sources to draw conclusions from these problems. This article has found that there are various ethical violations in political surveys that have been carried out for some time.  The problem relates to the unholy alliance with political consultants, contemporary business models, manipulation and misleading survey results, and survey method techniques. The recommendation from this article is that political pollsters should prioritize integrity, transparency, and accountability over profit. This will certainly be positively correlated with developing democracy in Indonesia.
Amil Zakat as the Citizen Political Participant with Religious Philantrophy Face
Authors: Prakoso Rayhan Aulia , Hakim Muhammad Lukman , Tawakkal George Towar Ikbal
Published: October 2022

Indonesia’s not-totally-state-centered zakat management policy makes amil zakat in Indonesia have double-identity. It’s not only as an Islamic law formalization in state level, but also as a medium for non-parties citizens' political participation in civil level. By using literatures study, this research aims to analyze head-to-head between Amil Zakat Institute (Lembaga Amil Zakat/LAZ) YASA Malang and everyday-maker. This research also aims to enrich everyday-maker perspective, because in fact there are so many Muslim social institutions which have some similarity with everyday-maker, but with some differences in their motives and characteristic of program. Everyday-maker is a new typology of citizen political participation found by Bang and Sorensen at 1999, where citizens are fixing their daily problems theirselves, instead waiting for government to fix it. However, everyday-maker starts from Danish’s upset with their government works, meanwhile LAZ YASA Malang starts from the concept of Islamic philantrophy and spirit of building lowest-level Muslim’s socio-economics independency. This research, because of the difference of motive between LAZ and everyday-maker, successfully finds some novelty rather than the previous everyday-maker researches, like one-eighth amil’s portions as the source of amil zakat salaries and government involvement in the legality. Something else that differentiates LAZ and everyday-maker is a theological value that becomes the basic, where everyday-maker works done by LAZ is based on belief about Allah’s help and grace in the movement.

Published: October 2022

Rejection of manuscripts by academic journals can be devastating for the early-career family medicine faculty members. Taking experience from teaching early-career underrepresented in medicine faculty members writing and scholarship skills, we identify and explain five lessons to be learned from rejected manuscripts. The five lessons are: (1) rejections teach journal scope, (2) rejections teach process, (3) rejection should lead to resubmission, (4) rejections reflect writing effort, and (5) rejections happen to papers, not authors. Early-career family medicine faculty can use these lessons for reassurance and to adapt behaviors to remain in the scholarship arena.
The Tradition of Diaries in the Ukrainian Hetmanate
Authors:   St. Petersburg Institute of History of Russian Academy of Sciences, Tairova-Yakovleva Tatyana G.
Published: October 2022

The article deals with the issue of the existence of a tradition of keeping diary entries in the Ukrainian Hetmanate (17th – early 18th centuries), similar to those diaries that were kept at that time in Western Europe. In order to understand the origins of the diary tradition among the Cossack elite, born, brought up and educated in the Polish–Lithuanian Commonwealth, the author turns to the analysis of traditional for the Polish handwritten culture “diariushs” and characterizes the most famous examples. The article discusses the “diariushs” of representatives of the military elite that have survived to this day, namely of Dmitry Tuptala (Rostovsky), Philip Orlik, Ya. Markovich and others. The author suggests the existence of earlier “diariushs” (in particular, by the participant of the Khotyn war S. Zorko), the full texts of which have not survived to this day. This conclusion is confirmed by the “diariush” of the clerk Ivan Bykhovets, introduced into scientific circulation by the Ukrainian historian L. Okinshevich in 1930, but for objective reasons remained practically unknown in historiography. It is noted that this “diariush” is fully consistent with the Polish counterparts and contains a number of unique descriptions.
I. V. Vuich’s “Journal” as a Historical and Cultural Source
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Vinogradskaya Nataliya L.
Published: October 2022

The article is devoted to the youthful diary in letters of Ivan Vasilyevich Vuich (1813–1884). Thе diary is kept in the Manuscript Department of the Russian State Library. The author of the diary came from the province to St. Petersburg to enter the School of Cavalry Junkers and Ensigns of the Guard. He lived in the capital for a year, preparing to the examinations and attending theaters, concerts, exhibitions, etc. in his leisure time. In 1830 he entered the School and studied there for another year, and then went with his regiment on a Polish campaign. In total, he lived in St. Petersburg for two years (1829–1830), during which he kept his diary in the form of letters addressed to his relatives. This genre is intermediate between a diary and a letter; it differs from a diary by the presence of a clearly designated addressee to whom the text is oriented. In particular, Vuich in his notes seeks to introduce relatives to the entertaining phenomena of metropolitan life. Thus, Vuich’s “journal” represents a lot of details of the city’s daily life; this makes it a useful source for studying the cultural history of the first third of the 19th century and for commenting on fiction and epistolary texts of this period, including letters of N. V. Gogol.

The Poetic Legacy of P.A. Vyazemsky: Alphabetical and Bibliographic Description of Published, Handwritten (Archived) and Controversial (Dubielzig) Writer’s Texts
Authors:   Mordovia State University, Vasilyev Nikolay L. , Zhatkin Dmitry N. ,   Penza State Technological University
Published: October 2022

The article summarizes the results of a long-term study of the poetic activity of P.A. Vyazemsky (1792–1878), reflected in his lifetime publications, autobiographical, memoir and epistolary materials preserved in the writer’s archive. The works of the poet were published many times, including “Complete works” in 12 volumes (1878–1896). However, none of these publications, including Soviet ones, fully reflect Vyazemsky’s poetic legacy (even if we sum up such publications). In addition, the 12-volume collection contains some works of other authors mistakenly placed there. The existing bibliographies of the poet’s texts published by M.N. Longinov (1862), S.I. Ponomarev (1879), and D.D. Yazykov (1904) are also full of lacunae, inaccuracies, and contradictions. System accounting and textual interpretation of manuscripts (autographs, lists) of Vyazemsky’s poems and his poetic sketches in the Ostafyevsky archive (RSALA) and other archives make it possible to significantly supplement the idea of the writer’s late work and literary and social position, to clarify his authorship in relation to a number of controversial texts in this regard (“For the current war”, “Who needs whom more?”, “Rampant life in carlsbad we are...” etc.). It is necessary to take into account the poetic inserts in translated and original dramatic works written by Vyazemsky alone or in collaboration with V.L. Pushkin and A.S. Griboyedov. The result of a comprehensive study of the totality of direct and indirect evidences on Vyazemsky’s work was the authors “alphabetical index of P.A. Vyazemsky works,” which includes about 1350 bibliogrammes that demonstrate variations of names and the first lines of particular poems, information about their first publications or archival sources, and the necessary historical and literary commentary on them.
The First Meeting of Anna Karenina and Alexey Vronsky: the Story of One Scene’s Creating
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Gorodilova Natalia I.
Published: October 2022

This article is devoted to the creative history of the novel “Anna Karenina” by L.N. Tolstoy. The author consistently restore the stages of the writer’s work on the scene describing the acquaintance of Anna Karenina and Alexey Vronsky on the material of autographs and authorized manuscripts. Interest in this episode is due to the fact that it lies the tie of the main conflict tragically refracted in the destinies of heroes. Presentation of archival documents, only partially published in Tolstoy studies, allows you to look into the creative laboratory of the writer and to trace the evolution of the artistic intent. Numerous corrections reflected in manuscripts convincingly testify that Tolstoy was not satisfied with the found art solutions. The plot of dating in general, was reflected in the early autographs, but the scrupulous work allowed the author to create a complex image: mentioning in a conversation between Vronsky and Oblonsky of all future participants of the drama, a description of the gradually approaching train — all this precedes exit to the scene of the main female character. The episode entered into the narrative with an accident gives rise to a premonition of future denouement. The main difficulty for the author was a way to present an image of the nascent feeling between Anna and Vronsky: Tolstoy went on the way to deepen the experiences of characters, describing their meeting as a fateful. The portrait of Anna: round and round the character acquired the features that allowed Tolstoy to create a charming female image and great personality. As a result, the main idea of the writer about the love of Anna was embodied as a natural need for living life.
The Scene of the Court Session in L.N. Tolstoy’s Novel “Resurrection”: the Space of the Material World in the Novel
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Matveeva Inga Yu.
Published: October 2022

The аrticle is devoted to the organization of the objective, material world in the novel “Resurrection” by L.N. Tolstoy, which is in inseparable connection with the writer’s ideas about the two levels of life, where material and earthly life is rigidly opposed to the true spiritual life. The writer presents the human world as a world of things and objects, a world from which its spiritual content is withdrawn, so that human life becomes “animal”, unnatural and criminal, and earthly reality contradicts the basic laws of God. The article examines the scene of the court session, which became the starting point for the development of events in the novel, and also determined the development of the main motifs and images of the work. The scene was carefully redrawn and for the first time in all its plot elements appeared in the first completed version of the novel. The article offers a comparative analysis of a number of fragments of the court scene in the original editions of the novel and in the final text of the work. The article shows how as the writer works on the text and how the description of the courtroom space and the characters images become more detailed, filled with material characteristics and elements. The scene of the court session implements the idea of material as an absurd, “inverted” reality, where criminals are judges, and the desire for justice turns into a crime.
Right Anterior Minithoracotomy for Redo Aortic Valve Replacement After Coronary Artery Bypass Grafting with Bilateral Internal Thoracic Artery: a Case Report
Authors: Nishiori Hironobu , Sakata Tomoki , Matsumiya Goro
Published: October 2022

A 63-year-old male, with a history of coronary artery bypass grafting
using bilateral internal thoracic artery grafts, underwent surgical
aortic valve replacement. Avoiding the graft injury, we selected the
right anterior mini-thoracotomy approach under cardiac arrest with
systemic hyperkalemia with remaining bilateral internal thoracic artery
grafts open. Deep hypothermia was induced to obtain more reliable
myocardial protection. We believe this strategy can be considered as a
therapeutic option in patients requiring aortic valve replacement but
unsuitable for transcatheter aortic valve replacement.
NAPPN Annual Conference Abstract: Measurement of Temporal Crop Responses to Fertilizers using Custom Phenotypes from Multispectral Aerial Imaging
Authors: Gruber Barrett , Jr Gary Nijak, , Roeth Jeremiah
Published: October 2022

Measurement of key crop physiological traits using high resolution
aerial imagery with unmanned aerial systems (UASs) holds enormous
potential to increase consistency and accuracy of data collected for
field evaluations. Here, we demonstrate temporal corn response to
fertility treatments using repeated measurements followed by an
area-under-the-curve progression analysis. Radiometrically calibrated
multispectral datasets were used to calculate standard vegetative
indices as well as to leverage models that approximate leaf area,
nitrogen content, chlorophyll content, and canopy uniformity. In
addition, digital elevation models can be employed to measure relative
canopy heights and spatial variability in the field. Taken together,
these digital assessments allow for a researcher to have significant
insight into experiment outcomes during the growing season, including
the identification of relative yield potential. This approach automates
and standardizes the acquisition of key phenotypes that can be used to
more efficiently evaluate field trials across multi-location programs.
Quantitative Interactions Between Phloem-Xylem Sap Flows, Root Pressure and Predawn Water Potentials.
Authors: GOESCHL D. JOHN
Published: October 2022

For many years, mechanistic studies of root pressure and xylem
exudation in decapitated plants have focused on the uptake of mineral
nutrients from the soil and the resulting osmotic potential and influx
of water into the xylem. Theoretical considerations and published
evidence of downward water flow through the phloem into the apoplast of
root tips in intact (non-decapitated) plants support an old concept that
phloem sap flow may contribute significantly to root pressure and upward
xylem flow (i.e. a “push-pull” effect). Phloem loading and osmotic
influx of water into leaf sieve tubes at night may contribute to
negative predawn water potentials.

Authors: Boskovic-Sekulic Jelena , Sekulic Igor , Rancic Nemanja , Stanic Mina , Jovicevic Milos , Perisic Nenad
Published: October 2022

Introduction. Portal vein (PV) thrombosis (PVT) is a partial or complete obstruction of blood f low as a result of a thrombus mass in the lumen of PV. In the acute phase, the symptoms such as right upper quadrant pain, nausea, and fever are unspecific. A diversity of subacute and chronic symptoms is associated with complications related to PVT and portal hypertension. Case report. A 50-year-old female was admitted to the hospital due to acute abdominal cramping pain. The pain lasted for 15 to 20 min and was followed by defecation of normal stool and hematochezia on three occasions. The abdominal pain recurred after several hours, again followed by hematochezia and tenesmus every 10 min. After admission, a colonoscopy was performed, and it revealed vulnerable, erythematous mucosa of the colon with contact bleeding from the lienal flexure to the rectosigmoid junction. During the colonoscopy, a biopsy was performed. A computed tomography (CT) scan revealed partial PVT of intrahepatic branches of PV, and thrombosis of the inferior mesenteric vein. After conservative treatment with low molecular weight heparin (LMWH) and other supportive measures, the digestive bleeding ceased, and defecation became normal. During the one-month follow-up, the patient had no complications, and the control CT scan revealed normal PV flow without thrombosis. Conclusion. Although rare, a non-malignant and non-cirrhotic PVT should not be neglected in the differential diagnosis because timely and vigilant therapy with LMWH can lead to complete resolution without serious complications.

Authors: Pete Maria , Ruzic Maja , Kovacevic Nadica , Petric Vedrana , Milosevic Ivana , Preveden Tomislav
Published: October 2022

Background/Aim. Quantitative hepatitis B virus (HBV) surface antigen (qHBsAg) has become increasingly wide-spread in the last few years in both diagnostic and therapeutic protocols for HBV infection. Numerous studies have proposed it as a surrogate marker for covalently closed circular DNA (cccDNA). The aim of the study was to determine the correlation between qHBsAg and HBV DNA viremia in untreated patients. Methods. The study included 112 untreated patients diagnosed with chronic HBV infection. Demographic and other data from medical records and laboratory analyses, taken as part of routine chronic HBV infection diagnosis with the determination of qHBsAg and HBV DNA viremia, were recorded for all patients. Results. The average age of the patients included in the study was 48.27 ? 15.14 years; males (58%) were more represented. qHBsAg levels had a high-intensity positive correlation with HBV DNA viremia. The concentration of qHBsAg, HBV DNA viremia, and the concentrations of alanine aminotransferase and aspartate aminotransferase showed statistically significantly higher values in HBV e antigen (HBeAg)-positive than in HBeAg-negative patients. Conclusion. Our study showed that qHBsAg has a high-intensity positive correlation with HBV DNA viremia. The use of qHBsAg is essential for determining the phase of chronic HBV infection, assessment of the success and length of treatment, as well as for safe discontinuation of antiviral therapy with a lower risk of relapse.

Consumer Behavior and Business Strategy During the Early Stages of the COVID-19 Pandemic
Authors: Setyawan Andhy , Tjiptono Fandy , Adriana Dadi
Published: October 2022

Consumer behavior is dynamic and contextual. An individual’s consumption habit is formed over time and is influenced by many internal and external factors. The consumption habit itself reflects what, where, when, why, and how to choose, purchase, consume, and dispose goods and services. When the COVID-19 pandemic hit, all consumers around the globe were forced to adapt into the never-happened-before realities, such as regional and national lockdowns, stay-at-home campaign, social/physical distancing policy, mandatory quarantine, and self-isolation. Utilizing available and accessible published materials, this paper aims to examine the significant impacts of the outbreak on consumer behavior in Indonesia and identify how the businesses respond to the changes in consumer behavior caused by the coronavirus. The timeframe of the analysis focuses on the early stages of the pandemic. Using the framework developed by Sheth (2020), the present study found supporting evidence of the eight impacts of COVID-19 on consumer behavior (e.g., hoarding behavior, improvisation, and the adoption of digital technology) in Indonesia. Furthermore, companies were found to respond to the pandemic and changes in consumer behavior by employing a combination of four business strategies: survival strategy, synchronizing strategy, stretching strategy, and shifting strategy.

Authors: Ulum Hakan
Published: October 2022

The purpose of this meta-analysis is to combine the results of experimental research completed between 2012 and 2022 and to examine the effects of different integrated STEM approaches on the attitudes of elementary school children. In the meta-analysis for the study on the effects of several integrated STEM approaches on the attitudes of elementary school children, five studies were selected based on particular criteria. The study included subgroup analyses in addition to exposing the overall effect of various integrated STEM approaches on the attitudes of elementary school children. According to the research findings, the Hedges g value, which is calculated to be 0.279 for the total effect size of diverse integrated STEM approaches on the attitudes of elementary school pupils, shows a small influence. In addition, the results of the analysis revealed that the impacts of different integrated STEM approaches on the attitudes of primary school pupils did not differ according to grade levels, but differed according to attitude area and integration.

Published: October 2022

In this study, it is aimed to develop a measurement tool to determine teachers' professional value-oriented living tendencies. By scanning the literature, the scale development stages were followed and a draft scale form with 50 items was created. The prepared draft form was applied to 25 teachers as a preliminary test and then rearranged in line with expert opinions. The prepared form was applied to a research group consisting of 1130 teachers working in public schools (primary school, secondary school and high school) in the central districts of Ankara in the spring term of the 2020-2021 academic year. Study Group 1 data were used to determine the validity and reliability of the scale, and Study Group 2 data were used for CFA. EFA was applied to the data obtained from 300 teachers, called Study Group 1, within the scope of validity and reliability study. In the second stage, Confirmatory Factor Analysis (CFA) was conducted on the data obtained from 875 teachers, called Study Group 2, in order to verify the factor structure of the scale in another sample. As a result of the exploratory factor analysis, it was determined that the scale had a three-factor structure. The Cronbach Alpha internal consistency coefficient was 0.98 for the overall scale, 0.96 for the 1st sub-factor, 0.77 for the 2nd sub-factor, and 0.86 for the 3rd sub-factor. As a result of confirmatory factor analysis, the RMSEA value was found to be 0.049. In addition, the GFI, AGFI, CFI, NFI and NNFI values, which are expressed as goodness fit indices, are found to be 0.99, which is very close to 1, which shows that good fit values are obtained. As a result of the analyzes made, a 33-item scale form with the necessary measurement reliability was developed to serve to measure the professional value-oriented life tendencies of teachers.

Authors: Egerer Azizeh , Schaefer Zoie , Larson Laurie
Published: October 2022

OBJECTIVE

To determine diagnostic accuracy of a point-of-care antibody-screening test by determining sensitivity, specificity, and overall accuracy when compared to reference standard tests for antibody against core vaccine viruses canine adenovirus (CAV), canine parvovirus (CPV), and canine distemper virus (CDV). A further aim was to provide the practitioner with information to guide selection of vaccinal antibody testing methods.

SAMPLES

Canine sera from across North America were submitted to a fee-for-service titer-testing laboratory. Samples came from healthy pet dogs with known core vaccination history (n = 431) as well as unvaccinated dogs held in isolation (132). This study examined a total of 563 samples for CDV/CPV and 183 for CAV.

PROCEDURES

Serum virus neutralization assays determined antibody titers for CDV and CAV. Hemagglutination inhibition assay determined antibody titers against CPV. All sera were also tested by point-of-care dot blot ELISA (index test).

RESULTS

For all 3 viral antigens, the index test provided sensitivity ranging from 96.03% to 96.75% and specificity ranging from 87.50% to 94.33%. Overall accuracy ranged from 93.43% to 95.91%.

CLINICAL RELEVANCE

The index test correlates well with reference standard tests and is a reliable, rapid screening test for detection of protective vaccinal antibody against CAV, CDV, and CPV in healthy dogs over 20 weeks of age. An accurate assessment of immunity allows clinicians to administer core vaccines appropriately as needed, avoiding unnecessary risk of adverse vaccine events.

OBJECTIVE

To demonstrate the efficacy and safety of mesenchymal stem cells (MSCs) for xenogeneic use with intra-articular administration in dogs with osteoarthritis.

ANIMALS

80 client-owned dogs with naturally occurring osteoarthritis in elbow or hip.

PROCEDURES

A multicentric, double-blinded, parallel, randomized and placebo-controlled clinical trial was performed. After intra-articular injection of equine umbilical cord MSCs, dogs were reexamined at weeks 4, 8, and 12 using a force platform (gait analysis), orthopedic assessment, and validated owner questionnaire. Eighteen months after treatment, a long-term follow-up was done.

RESULTS

Best results were obtained 8 weeks after treatment, where 63% of the patients showed an improvement in the gait analysis. Also 8 weeks after treatment, 77% of the dogs improved in the orthopedic examination; 65% of the owners considered that the treatment improved their pet’s quality of life 8 weeks after treatment. The long-term follow-up revealed that 59% of the owners observed a duration of effect longer than 6 months after a single intra-articular injection of equine umbilical cord MSCs. No systemic or permanent adverse events were detected at any time point.

CLINICAL RELEVANCE

Results of this study demonstrated the safety and efficacy of intra-articular administration of xenogeneic MSCs for the treatment of canine osteoarthritis.

Authors: Wang Jiajie
Published: October 2022

The amount of information available in modern life is very high. And people's knowledge about what kind of genre they like or prefer, the richness of content and the frequency of use will affect the quality of their animation works and their style. Therefore, how to make animation reach a higher level of simulation has become one of the topics of social concern nowadays; with the advent of mobile Internet era, more and more people like this social platform, and in this environment, we need to personalize ourselves and integrate into it faster through various technical means. In this paper, researchers focus on the reconstruction of crowd movement trajectory based on the optical flow constraint equation (SDH) after modification. Since lasers, cameras and other devices have high-intensity pixel resolution characteristics as well as better directional characteristics, we can use these features to design and build the function; then we can complete the relevant actions according to the prototype model under certain conditions, realize the simulation of the scene according to its requirements, and finally complete the required functions of the whole system. Finally, the feasibility and effectiveness of the optical flow constraint equation and the optimized action model in practical applications are verified through experiments; at the same time, this also provides reference values for relevant staff.

El Acuífero Región Carbonífera, es uno de los 28 sistemas hidrogeológicos existentes en el Estado de Coahuila y también de los que más presiones sufre, debido a la actividad minera y la sobreexplotación. Este estudio se enmarca en la porción oeste de dicho acuífero, abarcando el Ejido Morelos y la Colonia El Nacimiento, ambos en el municipio Melchor Múzquiz. En dicha área se tomaron muestras en 14 sitios (4 pozos, 6 norias, 2 manantiales y 2 secciones del Río Sabinas), con el objetivo de caracterizar desde el punto de vista hidrogeoquímico e isotópico estos cuerpos hídricos y así obtener un modelo conceptual de este sector. Los resultados obtenidos muestran la variabilidad química de las aguas muestreadas, clasificándose como aguas de tipo Bicarbonatada-Cálcica, Bicarbonatada-Sódica, Sulfatada-Cálcica y Clorurada-Sódica, lo cual sugiere la ocurrencia de variados procesos que afectan la calidad del recurso, entre ellos la salinidad. Desde el punto de vista isotópico se propone un origen meteórico para la mayoría de los cuerpos hídricos en estudio, cuya zona de recarga proviene de la Sierra de Santa Rosa. Sin embargo, procesos como la evaporación superficial, la disolución de sales y el intercambio iónico generan variabilidad química y fraccionamiento isotópico lo que condiciona firmas isotópicas más pesadas y aguas más enriquecidas y salinas. Estos elementos se representan en un modelo geohidrológico e isotópico conceptual, que integra ambas interpretaciones y muestra la complejidad hidrogeológica de la región en términos de calidad del recurso.
