AbstractThe aim of this study was to estimate the effect of tube voltage on the scattered dose in a computed tomography (CT) room. To this end, we conducted experiments using anthropomorphic phantoms and a CT scanner at different tube voltages during CT. The scattered dose was measured using an electronic pocket dosemeter at 50-cm intervals from the centre of the gantry. The structure of the CT room was measured at 57 points (28 points in the front of the gantry (on the bed side), 6 points on the side of the gantry and 23 points behind the gantry) to be up to 200 cm. We compared the scattered dose distributions between 80 and 120 kVp at heights of 50, 100 and 150 cm above the floor surface. The scattered dose was reduced by ~30% when the tube voltage was reduced from 120 to 80 kVp.

Background:
Temozolomide (TMZ) is an alkylating agent used to treat glioblastoma. However, the pharmacokinetics of TMZ to establish a treatment strategy for patients undergoing hemodialysis (HD) remain unclear. In this case report, we evaluated the pharmacokinetics and HD removal rate of TMZ in a patient with glioblastoma undergoing HD to determine optimal dosing of TMZ.

Methods:
A 78-year-old man with glioblastoma who underwent HD 3 times a week was treated with TMZ concomitant with radiotherapy. One dose of TMZ was prescribed at 75 mg/m2 on the day before HD and another dose of 37.5 mg/m2 on the day before non-HD. Peak and trough concentrations (1 hour and 12 hours after dosing, respectively) were evaluated before HD and on non-HD days. HD removal rate of TMZ was calculated based on the predialyzer and postdialyzer plasma concentrations. Furthermore, the TMZ plasma concentrations were measured using liquid chromatography–tandem mass spectrometry.

Results:
The mean plasma peak and trough concentrations ± SD after 75 mg/m2 TMZ were 2917 ± 914 and 108 ± 17.6 ng/mL, respectively. Those after 37.5 mg/m2 TMZ dosage were 1305 ± 650 and 53.8 ± 11.8 ng/mL, respectively. The mean HD TMZ removal rate was 84.9 ± 1.9%.

Conclusions:
TMZ was tolerable in patients undergoing HD. Based on the data from a single individual pharmacokinetic perspective, the pharmacokinetics of TMZ in this patient undergoing HD were comparable with those observed in patients with normal renal function. In addition, it may be reasonable to administer TMZ after HD because of the high HD removal rate.
Efficacy of belimumab for severe childhood-onset systemic lupus erythematosus with diffuse proliferative glomerulonephritis: A case report
Authors: Hu Ying , Yuan Jing , Wang Bo , Ma Liang , Zha Yan 
Published: August 2023

Introduction:
Therapy of childhood-onset systemic lupus erythematosus (cSLE) with drugs is unsatisfactory. Some new drugs such as belimumab and rituximab may improve the course of severe cSLE, although there are few reports on treatment efficiency for these new drugs, especially belimumab.

Case presentation:
Here we report on a 16-year-old girl who was diagnosed with cSLE at the age of 13. After several immunosuppressive treatments, which included high-dose steroids, hydroxychloroquine sulfate, cyclophosphamide, etc for blood system damage, she showed little clinical improvement and developed severe pericarditis. Induction treatment with a combination of intravenous high-dose steroids, methylprednisolone, and cyclophosphamide was started, but, after 55 days, the patient developed lupus encephalopathy, lung infection, and lupus nephritis. After using high-dose steroids, cyclophosphamide, plasma exchange, gamma globulin, and appropriate anti-pulmonary inflammation drugs, treatment with tacrolimus was attempted but poorly tolerated by the patient and withdrawn. Eventually, in December 2019, belimumab was initiated on an off-label basis as a last resource to treat lupus nephritis. Belimumab was well tolerated by the patient and resulted in a rapid and marked improvement in clinical symptoms and reduction in proteinuria, serum complement levels and anti-double strand DNA antibodies titer; of note, the patient developed no infectious complications.

Conclusion:
Treatment with belimumab could result in prompt remission of severe cSLE with multiple organ damage without the pulmonary infection side effects for children deemed intolerant to conventional and second-line induction therapies. Belimumab should be considered as a potentially efficacious treatment in patients in severe childhood-onset systemic lupus erythematosus.

Published: August 2023

Objective:
The objective of this study was to investigate of the effect of piezzo and conventional osteotomy techniques on bone reserve in the osteotomy line and comminuted fracture ratios that is able to compromise bone to bone contact negatively.

Methods:
Bilateral sagittal split ramus osteotomy was performed on 12 fresh male Thracian curly caprine mandible. In the first group (n: 12) osteotomies were performed with piezzo device. In the second group (n: 12) osteotomies were performed with micromotor and manual osteotomes. Operative time was measured. The number of comminuted fractures, length and width of the osteotomy, and the space between the osteotomy lines was evaluated from 3-dimensional computed tomography scans.

Results:
The mean value of procedure duration was 320.4±10.76 seconds for piezo osteotomy and 238.8±8.29 seconds for conventional micromotor (P<0.0001). Number of comminuted fractures was 1.41±1.3 in piezoelectric group, 1.5±1.3 in conventional group and the difference was not statistically significant (p: 0,88). Osteotomy lengths and widths were 35.58±5.2, 2.196±1.9 and 36.23±5.05, 2.27±1.85 in the piezzo and conventional groups, respectively. (plengths:0,75; pwidths:0,92) The volume of the bony interface between the distal and proximal segments of the mandible after osteotomy was 166.3±184.2 mm3 in the piezzo group and 163.5±129.3 mm3 in the conventional group (p: 0,96).

Conclusion:
The piezo surgery and the conventional osteotomy were found to be similar in terms of the gap between the distal and proximal mandible and the number of comminuted fractures. The duration to perform the conventional osteotomy was found to be shorter than the piezo surgery.

Authors: Ambarwati Rita , Sari Dewi Komala 
Published: August 2023

Purpose
This study aims to determine the effect of Islamic branding, experiential marketing and word of mouth on college decisions and to find marketing strategies through strengthening Islamic branding based on experiential marketing to increase the number of students at Muhammadiyah-Aisyiyah Higher Education.

Design/methodology/approach
This study used a quantitative method, with data collection carried out using a survey method by giving questionnaires to respondents. The respondents' criteria are active students, at least in semester three, who have studied at Muhammadiyah-Aisyiyah Higher Education in Indonesia, using a sampling technique with accidental sampling. Data analysis used Partial Least Square - Structural Equation Modeling to determine the estimated results or model predictions.

Findings
The results showed a significant direct effect of experiential marketing, Islamic branding and word of mouth on college decisions. There is an indirect effect between experiential marketing and Islamic branding on college decisions through word of mouth, but the word-of-mouth variable could not mediate the relationship between experiential marketing and Islamic branding on college decisions perfectly.

A novel PZT-based high-power piezoelectric vibrator for ultrasonic motors: properties enhanced by Yb institution
Authors: Shi Jingjing , Qian Ning , Su Honghua , Yang Ying , Wang Yiping 
Published: August 2023

PurposeThe electrical properties of piezoelectric vibrators have a crucial influence on the operating state of ultrasonic motors. In order to solve the problem that the current piezoelectric vibrator generates a large amount of heat during vibration to degrade its performance, which in turn affects the normal operation of ultrasonic motors, this paper prepares a novel piezoelectric vibrator and tests its maximum vibration velocity under the working condition, which is more than twice as much as that of the current commercial PZT-8.Design/methodology/approachThe crystal structures of the samples were analyzed by using an X-ray diffractometer. For microstructure observation, samples were observed by scanning electron microscope (SEM). The quasi-static piezoelectric coefficient meter (ZJ-3AN) was used for piezoelectric measurement. Dielectric properties were measured by utilizing an impedance analyzer (Agilent 4294A) with a laboratory heating unit. Ferroelectric hysteresis loops were obtained using a ferroelectric analyzer (Radiant, Multiferroic 100). A Doppler laser vibrometer (Polytec PSV-300F, Germany) and a power amplifier were used for piezoelectric vibration measurements, during which the temperature rise was determined by an infrared radiation thermometer (Victor 303, China).FindingsThe ceramics exhibit enhanced piezoelectric performance at 0.1–0.4 mol% of Yb doping contents. The ceramic of 0.4 mol% Yb reaches the maximal internal bias field and presents a larger mechanical quality factor of 1,692 compared with that of 0.2 mol% Yb-doped ceramic, in spite of a slightly decreased dielectric constant of 439 pC/N, the unit of the piezoelectric constant, which is the ratio of the local charge (pC) to the frontal force (N) and electromechanical coupling coefficient of 0.63. The vibrator with this large mechanical quality factor ceramic displays a vibration velocity of up to 0.81 m/s under the constraint of 20 °C temperature rising, which is much higher than commercial high-power piezoelectric ceramics PZT-8.Originality/valueThe enhanced high-power properties of the piezoelectric vibrator by Yb doping may provide a potential application for the high-performance USM and offer the possibility of long-term stable operation under high power for special equipment like USM. In the subsequent phase of research, the novel PZT-based high-power piezoelectric vibrator can be utilized in the USM, and the motor's performance will be evaluated under aerospace conditions to objectively assess the reliability of the piezoelectric vibrator.

Based on the findings of this study, a roadmap of recommendations has been proposed to promote the adoption of environmental economic practices in the Nigerian construction industry. The implementation of these recommendations can help reduce the negative impact of construction activities on the environment and public health and contribute to the development of sustainable cities, communities and societies.Practical implicationsThe outcomes from this study can inform policy and decision-making by providing insights into the level of knowledge and awareness of environmental economic practices among construction professionals in Nigeria.Originality/valueThe findings from this study provide a baseline for assessing the level of knowledge and awareness of sustainable practices among construction professionals in Nigeria, which can inform future studies on the effectiveness of training and awareness programs.
Behavioural thermoregulation and food availability drive fine‐scale seasonal habitat partitioning in limpets
Authors: Virgin Spencer D. S. , Schiel David R. 
Published: August 2023

Abstract

Small‐scale spatial variation in temperature plays a key role in limiting the distribution of organisms in thermally heterogeneous environments. In the rocky intertidal zone, intra‐day temperature variation at small scales (cm–m) can easily exceed 30°C.

To experimentally test the impact of this small‐scale temperature heterogeneity on the distribution of an ecologically important limpet species (Cellana denticulata), boulders on an intertidal rocky reef in New Zealand were rotated and small‐scale temperature variability and food availability were measured throughout 1 year. Small‐scale variability in thermal tolerance, heart rate and heat shock protein expression was also measured to relate in situ limpet distributions with environmental conditions. Temperature variability was measured using limpet bio‐mimics and HOBO pendant temperature loggers, while food availability (chlorophyll a concentration) was measured on in situ concrete fibreboard tiles.

To measure limpet distributions, every tagged limpet on each of 18 boulders was followed from June 2021 to 2022. During each sampling, the location of each limpet, compass direction and slope of the surface that each limpet inhabited was measured. To test for physiological differences among limpets from each microhabitat, thermal tolerance and heat shock protein expression were measured in collected limpets; in situ heart rates and body temperatures were also measured sporadically on hot days.

Maximum predicted body temperatures (36–39°C), heart rates and actual body temperatures were greatest on equatorial surfaces (i.e. surfaces facing the equator) whereas food availability was greatest on poleward‐facing surfaces. During summer, limpets moved towards surfaces that minimised their body temperatures and maximised food availability, namely vertical and poleward‐facing surfaces and undersides of boulders.

Thermal tolerance, measured using Arrhenius breakpoint temperatures (mean ± SE: 34.7–35.8 ± 0.4–0.7°C) and flat line temperatures (36.2–37.4 ± 0.3–0.4°C), was similar among limpets facing different directions. Surprisingly, heat shock protein expression was relatively consistent throughout the year and among directions.

Overall, limpet populations are resilient to thermal stress because they effectively use behavioural thermoregulation to exploit cooler microhabitats that also have greater food availability during summer.

Assessment of carbon, oxygen, strontium, and lead isotopic variation in modern Colombian teeth: An application to human identification
Authors: Castellanos Daniel , DiGangi Elizabeth A. , Bethard Jonathan D. , Kamenov George , González‐Colmenares Gretel , Sanabria‐Medina César 
Published: August 2023

AbstractColombia faces the complex humanitarian challenges of locating approximately 100,000 missing persons and identifying thousands who are deceased. Identification is a difficult task in many cases, because the skeletonized bodies are deteriorated, missing person data are unavailable for comparison, and the provenance of the remains is often totally unknown. Isotopic analysis of human tissues (e.g., bone, hair, nails, and teeth) aid in the identification process of unknown individuals because they can provide valuable information on possible geographic origin. This project evaluated the isotopic variability of carbon (C), oxygen (O), strontium (Sr), and lead (Pb) in modern Colombian teeth according to city, department (a political designation similar to “state” in the US or Mexico), and one of four geographically determined regions of origin; and assessed its utility for human identification in Colombia. Isotopic data (O‐C‐Sr‐Pb) were analyzed from modern Colombians originating from the cities of Bogotá, Cali, and Neiva (n = 95); and these data were compiled with published Colombian data of individuals mainly from the city of Medellín (n = 61). Results indicate a wide range and overlap of O‐C‐Sr‐Pb isotopic distribution according to the defined categories. However, differences between coastal and lowland individuals are observed when using δ18O values, and differences between mountainous regions are observed when using 87Sr/86Sr values. In addition, this study suggests that the usefulness of isotopic analysis for unidentified individuals in Colombia would be with assigning them geographically using the designations of North, Central Andes, Eastern Andes, or Southwest Andes versus making classifications at a city or department level.

Authors: Santalucia Virginio , Hunt Robert , Murphy Molly 
Published: August 2023

SummaryThis case report describes the clinical and diagnostic imaging findings, treatment and outcome of a 3‐month‐old Thoroughbred foal referred for the evaluation of severe left forelimb lameness and presents the acquisition of a novel radiographic projection of the scapula used to achieve the diagnosis. No abnormalities were found with the standard radiographic examination of the left shoulder. A right dorsal 45° lateral‐ left ventral lateral oblique radiographic view was performed to evaluate the body of the left scapula. A longitudinal, minimally displaced fracture of the infraspinous fossa was diagnosed with this projection. Ultrasound was used in conjunction to confirm the diagnosis, assess the displacement of the fracture in the sagittal plane and evaluate soft tissue damage. The foal was treated conservatively with anti‐inflammatory drugs and stall rest. A radiographic follow‐up and clinical reassessment were performed, and the horse appeared sound, no atrophy of the region was appreciated and no radiographic abnormalities were found.
