Published: September 2024

AbstractA variety of fish species have proven instrumental in the investigation of evolution, behavior, ecology, and physiology, among many other fields. Many model systems (e.g., zebrafish, guppies, and three-spined sticklebacks) have been maintained by institutions and have had protocols written with respect to their husbandry. Here we present the protocols we have developed to maintain and breed a variety of Corydoras catfish species, which are native to the tropical Americas. Corydoras species are excellent systems for investigating behavior, ecology, and other topics, and our husbandry protocols would be suitable for nearly every species in the genus. In addition, these protocols are appropriate for a variety of softwater Amazonian species, and we present options for a variety of housing and husbandry conditions. On the whole, we suggest that, in a scientific laboratory setting, the use of remineralized reverse osmosis water is most appropriate and that in context, a single measure, total dissolved solids, can be used to monitor the water chemistry for water introduced to fish enclosures.

“Be Cool” Not Stressed: Scan Upper Extremity Vessels With Ease!
Authors: Arndt Lori 
Published: September 2024

Generalist sonographers across Canada are usually very familiar with performing a venous duplex study of the lower extremity. Performing a venous duplex study of the upper extremities is not as commonly performed in the majority of clinic settings but this article is geared toward pointing out how easy ultrasound imaging of the upper extremity vessels can be. The focus of this article will be on the innominate, subclavian and the superficial veins of the arm. Deep veins of the upper arm and forearm will also be discussed. Pathologies encountered in the upper extremity will also be mentioned along with correlative ultrasound images. A basic protocol for performing an upper arm deep venous thrombosis (DVT) study will be outlined. This article will hopefully be helpful for sonographers with all levels of experience by illustrating scanning techniques and tips that will aid in imaging the upper extremity vessels well.
Absent Cervical Gland, Cervical Length and Amniotic Fluid Sludge as Predictive Markers of Preterm Birth
Authors: Trieu Marcia , Zhu Cici , McGregor R , Barclay L. , Lopes Laudelino 
Published: September 2024

Background and Objective Preterm birth is one of the leading causes of neonatal and childhood death worldwide. Despite medical advancements, we often fail to predict and prevent preterm birth. The aim of this study is to evaluate the relationship between three cervical markers: cervical length, absent cervical gland area, and amniotic fluid sludge with the incidence of preterm birth. Material and Methods A prospective, correlational research study, was conducted at the Department of Medical Imaging, Obstetrical Ultrasound Unit, London Health Sciences Centre Victoria Hospital Campus, London, Ontario, Canada from April 1 2014-June 1 2015. The target population was pregnant women, 18 to 45 years of age, who may or may not have a history of preterm labour. The inclusion criteria were singleton pregnancies between 16 and 23 weeks gestation. Participants were excluded if they had a multiple gestation, a fetal demise, fetal anomalies, previous surgeries of the cervix, (i.e. Loop Electrosurgical Excision procedure, cone biopsy), cervical cerclage, placenta previa, and/or any other indication for preterm delivery other than spontaneous labour. Participants were recruited at their antenatal visits or ultrasound appointments and informed consent was obtained. Transvaginal ultrasound of the cervix was performed to assess for cervical length, absent cervical gland area and amniotic fluid sludge and correlated with the incidence of preterm birth. Results Two-hundred and fifteen women participated in this study. Thirteen were removed from the final analysis. The final sampling totalled 202 participants. Twenty-five participants met the criteria for preterm birth, delivering less than 37 weeks gestational age. The prevalence of short cervical length, measuring less than 2.5 cm was 2.3% (4/177) in participants delivered full term and 12% (3/25) among participants that delivered preterm. Absent cervical gland area was 10.2% (18/177) in participants that delivered full term and 16.0% (4/25) among participants that delivered preterm. The prevalence of amniotic fluid sludge was 6.8% (12/177) in participants that delivered full term and 16% (4/25) among participants that delivered preterm. Conclusion Cervical length measurement less than 2.5 cm did prove to be statistically significant with the incidence of preterm birth. Absent cervical gland area and amniotic fluid sludge, however, did not demonstrate a statistically significant correlation. Cervical length measurement, absent cervical gland area and amniotic fluid sludge did not demonstrate an association with chorioamnionitis.

Published: September 2024

Multiple intelligence theory can be used as a basis for assessing children's intelligence potential, the results or multiple intelligence profiles will be very useful for guidance and education. The challenges of era 4.0 and the characteristics of today's generation of learners encourage teachers to be able to innovate and develop the learning process continuously. One of the innovations that can be carried out is the implementation of multiple intelligence-based learning. For this reason, it is necessary to know the multiple intelligences that can be accommodated in learning biology on cell material. This research is a descriptive narrative research. The sample taken was total sampling using subjects as many as 7 grade 8 students and 1 science teacher. The research was conducted at Equal Bright School Bandung because this school is based on multiple intelligence in its learning. Data collection techniques were conducted by direct observation techniques to see the implementation of biology learning, interview sheets to describe learning from teachers and students, documentation in the form of photos and videos and multiple intelligence inventory questionnaire adapted from McKenzie (1999). The data collected from the analysis of lesson plans, interviews and multiple intelligence questionnaires were analyzed using descriptive methods, the calculations carried out in the form of categorization.Ã‚Â The results of the research show that the teachers' learning of the biology of the cells can facilitate several multiple intelligences, kinesthetic, naturalistic, interpersonal, visual-spatial, verbal and intrapersonal. The creation of a biology learning plan based on multiple intelligence and learning in the classroom is based on the dominant intelligence of the student.
