No. of bitstreams: 0 Previous issue date: 2021-12-01 This article aims to standardize 3D scanning and printing of dog skulls for educational use and evaluate the effectiveness of these anatomical printed models for a veterinary anatomy course. Skulls were selected for scanning and creating 3D-printed models through Fused Deposition Modeling using acrylonitrile-butadiene-styrene. After a lecture on skull anatomy, the 3D-printed and real skull models were introduced during the practical bone class to 140 students. A bone anatomy practical test was conducted after a month; it consisted in identifying previously marked anatomical structures of the skull bones. The students were divided into two groups for the exam; the first group of students took the test on the real skulls, whereas the second group students took the test on 3D printed skulls. The students' performance was evaluated using similar practical examination questions. At the end of the course, these students were asked to answer a brief questionnaire about their individual experiences. The results showed that the anatomical structures of the 3D printed skulls were similar to the real skulls. There was no significant difference between the test scores of the students that did their test using the real skulls and those using 3D prints. In conclusion, it was possible to construct a dynamic and printed digital 3D collection for studies of the comparative anatomy of canine skull species from real skulls, suggesting that 3D digitalized and printed skulls can be used as tools in veterinary anatomy teaching.

Abstract

Research has been conducted on sugarcane genomes. The authors have investigated the genome complexity of sugarcane via the use of large-scale expressed sequence tag program, and they report that a vast number of unique genes has been identified, and that 90% of sugarcane expressed genes have been tagged.

Abstract

We have sequenced a 2.5-kb DNA fragment of the B-2 DNA puff from the sciaridRhynchosciara americanaand have defined its transcription unit. This puff is active during the formation of the communal cocoon, which is important for successful metamorphosis of this species and coincides with the final cycle of polytenization in its salivary glands. The B-2 polypeptide, together with the products of two other previously characterized DNA puffs, seems to be engaged in an interaction that results in a gradual modification and hardening of the cocoon structure. The B-2 messenger is temporally regulated in apparent coordination with the other puff products. The predicted polypeptide has characteristics similar to polypeptides from previously sequenced DNA puff genes, in particular those from theR. americanaC-8 gene and theBradysia hygidaC-4 gene. The cloned sequence of the B-2 puff is differentially amplified in the three gland regions examined, achieving its highest amplification level of approximately fourfold (two extra cycles) in the anterior segment of the gland. The C-3 DNA puff sequence was also found to be differentially amplified in the different gland regions. Implications of the widespread presence of DNA amplification as a form of gene regulation in the Sciaridae are discussed. [ABSTRACT FROM AUTHOR]
