Factors influencing enhancement timing in a triple-phase abdominal CT angiography protocol in dogs
Authors: Davé Aditya C. , Ober Christopher P. , Rendahl Aaron 
Published: June 2022

Abstract

OBJECTIVE
To evaluate the enhancement accuracy of a triple-phase abdominal CT angiography (CTA) protocol in dogs and explore the patient, scan, and contrast parameters associated with accuracy of enhancement.

ANIMALS
233 client-owned dogs that underwent routine abdominal CTA.

PROCEDURES
During each CTA study, the subjective timing accuracy (early, ideal, late) of the 3 obtained vascular phases (arterial, venous, delayed) was scored by consensus (2 reviewers) at 4 target organs (liver, pancreas, left kidney, and spleen). These scores were evaluated for statistical associations with 21 study variables (patient, scan, and contrast medium). The objective enhancement (HU) for each target organ was also compared statistically with subjective timing accuracy scores and the study variables.

RESULTS
The study protocol performed best for the pancreas, moderately for the liver, and worse for the spleen and left kidney. Measurements of scan length and time were associated positively with phase lateness for most target organs and phases. Increased heart rate was the most significant patient factor associated positively with phase lateness within the liver (all phases), pancreas (arterial and venous phases), and kidney (arterial phase). Contrast medium variables were less associated with timing accuracy in this protocol. Objective enhancement (HU) correlated poorly with subjective phase timing accuracy and study variables.

CLINICAL RELEVANCE
Scan time, scan length, and heart rate were the predominant variables contributing to lateness in this canine abdominal CTA protocol. The findings of this exploratory study may aid in protocol adjustment and choice of included anatomy for dogs undergoing routine abdominal CTA.

Published: June 2022

Abstract

Purpose
The concept of cultural branding based on various narratives has been established in the marketing literature, but there is a lack of studies linking this concept with brand-related effects. The aim of this paper is to explore and explain the possible relationships between various brand narratives based on the changing meaning of retirement and brand associations.

Design/methodology/approach
An experimental design was used to test the proposed conceptual model and examine the impact of brand narrative on brand associations. Data were collected using an online survey from a random group of 432 respondents and analyzed using MANOVA.

Findings
Our research did not confirm that in the case of financial products, brand narratives represented by distinctive retirement cultural codes had an impact on brand associations. Partial relation was found only for brand personality.

Originality
This is the first study that explores brand narratives’ based on cultural codes relations with brand associations.

Abstract

Introduction
Inflammatory mammary carcinoma (IMC) is a rare disease with a poor prognosis and one affecting dogs. Inflammatory breast carcinoma (IBC) is a subtype of malignant breast cancer in humans with a high degree of malignancy and a similarly poor prognosis. Since the clinical symptoms and prognoses of both are similar, canine IMC has been considered as a model of human IBC. In this study, we newly established a stable IMC-derived cell line from a patient at the Yamaguchi University Animal Medical Center in Japan.

Material and Methods
The patient was a female toy poodle presenting with an inflamed mammary gland, which was diagnosed as IMC. The cell line was established from a tissue biopsy. Surface antigen marker (CD24 and CD44) expression was determined. Cystine/glutamate antiporter (xCT) expression was determined by Western blotting, flow cytometry and fluorescence immunostaining, and sulfasalazine was administered to ascertain if it suppressed xCT expression. Stem cell marker (Nanog, Sox2, Myc and Klf4) expression and aldehyde dehydrogenase (ALDH) activity were also investigated.

Results
The cultured cells showed xCT, and its suppression showed downregulation of stem cell markers and ALDH activity. Stable cell proliferation was verified.

Conclusion
A new canine IMC-derived cell line was established. In the future, we aim to study the effect of xCT on the maintenance of cancer stem cell properties in canine tumours, and propose a new therapeutic method for the treatment of canine IMC by targeting xCT.

Abstract

Introduction
Dairy cows may infrequently give milk tinged with blood after calving, which is a condition termed haemolactia. Economic losses for dairy farmers are caused by cases of haemolactia because of the condemnation of such milk, potential contamination of good bulk tank milk with haemolactic milk, and need for veterinarian intervention. This study was performed to elucidate the oxidative status of dairy cows with haemolactia during the peripartum period.

Material and Methods
Plasma glutathione peroxidase, malondialdehyde (MDA) and superoxide dismutase concentrations along with serum vitamin A, C and E concentrations were determined as indices of oxidative stress. The sampled dairy cows comprised two haemolactic (n = 11 and n = 6) and two non-haemolactic (n = 11 and n = 6) groups.

Results
On the first day when haemolactia was identified in colostrum (at mean 2.1 days after parturition), a significantly increased concentration of plasma MDA was noted in the haemolactic group. During the prepartum period, low levels of serum vitamin E were continuously observed from prepartum week 4 to the parturition day but only in the haemolactic group.

Conclusion
These results demonstrate that continuous low levels of serum vitamin E in the prepartum period may play a pivotal role as a requisite factor in the onset of haemolactia after calving.

Ways of Thinking (WoT) is a fundamental ability that is part of the mental act that students must learn to solve geometry problems. The purpose of this research was to describe how WoT is used to solve geometry problems. This research used the descriptive qualitative methodology with a holistic case study design and data collection techniques such as tests, interviews, observation, documentation, and triangulation. The subjects in this research were 35 fourth-grade students from Sambas Regency Public Elementary Schools, Indonesia. The research focused on three students with varying levels of cognitive abilities: low, medium, and high. The results showed that students with high, medium, and low cognitive capabilities performed mental acts with the corresponding WoT. Students with high, medium and low cognitive capabilities were more likely to work on questions that required interpretation. Besides, it also revealed that errors committed students were learning errors, reading errors, careless errors, conceptual errors, and procedure errors. The implementation of WoT on the topic of geometry can be utilized as an alternate reference for mathematics teachers when developing teaching materials for mathematics learning to increase studentss' mathematical knowledge.

The gap between the concept image and the concept definition will greatly affect a person’s understanding of the concept. This study aims to reveal the gap between the concept image and the concept definition, and the causes of the emergence of the gap. The research subjects were 16 first-year mathematics students at one of the universities in Aceh, Indonesia. Data were obtained from the results of written tests and in-depth interviews. This qualitative research with a phenomenological study approach was analyzed descriptively. The results showed that the gap that occurs in the concept includes: the division of a non-zero number by zero yields infinity, the concept of dividing zero by zero is zero, the concept of dividing a number by zero is the same as the concept of the limit, e.g., , and the concept of the left-hand limit as means that the satisfied value of x is all negative numbers such that . The emergence of these concept images results from the subject's learning experience at school and a calculus course. This finding provides insights and considerations for educators to comprehensively introduce students to the concept of infinity to avoid misunderstandings in limit and next materials.

Various methods and approaches have been used to support English learning. However, there is still a lack of information on how the grammar competence of vocational students can be improved in the Malaysian context. This study aims to build the Omygram learning chart and identify its effects on the achievement level of the students in Program Vokasional Menengah Atas (PVMA), or the upper-secondary vocational programme, on their English grammar competence. The study involved two secondary schools in Johor, Malaysia, employing a quasi-experimental design. A descriptive analysis from SPSS showed the increment in the mean score for the post-test of the treatment group of 5.58, higher than the control group (0.33) after the intervention was applied. The results of t-test showed no significant difference in achievement between pre-test and post-test for the control group [p = 0.504, (p 0.05)]. On the other hand, the result of the t-test for the treatment group showed a significant difference in achievement between the pre-test and post-test [p = 0.000, (p0.05)]. Students’ motivation after using the Omygram learning chart was also high. In conclusion, the development of the Omygram learning chart is proven to effectively increase students’ achievement in English. This confirms that developing learning aids improves students’ grammar competence and motivates them to learn the language better. As a result, the goal of producing a skilled workforce in TVET (Technical Education and Vocational Training) and possessing soft skills will be more achievable.

Published: June 2022

Objective To identify risk factors for quadriceps muscle strain injury in sport. Design Risk factor systematic review. Literature Search A systematic search was conducted in the MEDLINECINAHL, Embase, AMED, AUSPORT, SPORTDiscus, PEDro, and Cochrane Library databases (from inception to September 2021). Study Selection Criteria Studies reporting prospective data to evaluate risk factors related to index and/or recurrent quadriceps muscle strain injury. Data Synthesis A risk-of-bias assessment (using a modified Quality in Prognosis Studies tool) was performed, and we used best-evidence synthesis to qualitatively synthesize the data to quantify relationships between risk factors and quadriceps muscle injury. Results Sixteen studies were included, capturing 2408 quadriceps injuries in 11 719 athletes. Meta-analyses were not performed due to clinical heterogeneity. The dominant kicking leg (over 3154 individuals, 1055 injuries), a previous history of quadriceps muscle injury (6208 individuals, 975 injuries), and a recent history of hamstring strain (4087 individuals, 581 injuries) were intrinsic factors associated with quadriceps injury. Extrinsic factors relating to the preseason period and competitive match play increased quadriceps injury risk; participating at higher levels of competition decreased quadriceps injury risk. Age, weight, and flexibility (intrinsic factors) had no association with quadriceps injury. Conclusion Previous quadriceps injury, recent hamstring injury, the dominant kicking leg, and competitive match play were the strongest risk factors for future quadriceps muscle injury in sport.

Daerah Khusus Ibukota Jakarta merupakan dataran rendah dengan intensitas hujan yang tinggi pada periode tertentu. Saat ini curah hujan diukur secara manual oleh petugas dengan mengunjungi secara langsung alat pengukur curah hujan Ombrometer yang ditempatkan di sejumlah titik yang berdekatan dengan beberapa sungai di Jakarta. Dengan prosedur seperti itu maka pengukuran curah hujan menjadi tidak efisien secara waktu dan biaya karena memerlukan petugas yang harus mengunjungi lokasi pengukuran secara langsung dan memerlukan beberapa proses tambahan untuk mendapatkan nilai pengukuran. Hal tersebut akan menyulitkan jika data curah hujan diperlukan secara real time seperti untuk keperluan peringatan dini banjir. Untuk mengatasi masalah tersebut maka diperlukan sistem pengukur curah hujan yang dapat mengukur curah hujan secara otomatis dan mengirimkan hasil pengukurannya secara real time melalui jaringan. Pada penelitian ini dikembangkan sistem pengukur curah hujan berbasis IoT dengan menggunakan metode waterfall yang terdiri atas tahap pendefinisan kebutuhan, perancangan sistem, implementasi sistem, dan pengujian sistem. Sistem tersebut berbasiskan sensor pengukur curah hujan tipping bucket yang nilainya dapat dibaca dan diproses langsung oleh perangkat IoT NodeMCU ESP8266. Hasil pengujian telah menunjukkan bahwa seluruh kebutuhan fungsional sistem yang telah didefinisikan dapat berfungsi dengan baik.

Published: June 2022

This study aims to determine the comparison of student achievement with field-dependent (FD) and field-independent (FI) cognitive styles. The method used in this research is a comparative descriptive method with a quantitative approach. The sample consisted of 30 prospective physics teacher students who were studying at the University of Mataram. Research data were taken using the Group Embedded Figure Test (GEFT) and documentation of the study result card (SRC). GEFT is used to determine cognitive style while documentation is used to determine the cumulative achievement index (CAI) of students. Based on the results of the t-test at the 95% confidence level (α = 0.05) with the degree of independence (dk = 2= 28), it shows that there are significant differences in learning achievement between FI and FD students. The average learning achievement of FI students (CAI = 3.15) tends to be better than that of FD students (CAI = 3.37).
