Background and objective: This study investigated the occurrence characteristics of street tree management factors basedon different special-purpose areas with emphasis on citizen participation in data collection. Methods: We collected growth and management data of street tree sections and individual trees within sections using amonitoring form developed for street trees in four special-purpose areas in the urban area of Chuncheon. We used a binarylogistic regression model to analyze the probability of occurrence for each management factor (pruning traces, signblocking, disease and pest, felled trees, piled objects, and broken branches). Results: The probability of occurrence of management factors varied by special-purpose area, which was related to thecharacteristics of each area. Conclusion: This study suggests the need to develop efficient street tree management strategies by prioritizingmanagement factors in consideration of differences in special-purpose areas

Because of the potential negative influence on their hosts, ecto-parasites are of prime importance to numerous species. Ticks are among these, distributed worldwide, and potentially transmitting diseases while sucking blood of diverse hosts. The leopard cat (Prionailurus bengalensis euptilura Elliot, 1871) is the only felid left in the Republic of Korea following widespread anthropogenic disturbances that have resulted in the extinction of both Panthera species: the Siberian tiger(Panthera tigris altaica Temminck, 1844) and Amur leopard (P. pardus orientalis(Schlegel, 1857)). This study identifies ticks collected from a roadkill leopard cat retrieved in Seosan area in the Republic of Korea. Two ticks attached to the facial area of the carcass were identified as Japanese hard ticks, Ixodes nipponensis, based on mitochondrial cytochrome oxidase I. The matching sample was from Japan with 99.7% similarities, and the only available sequence on GenBank. This study reconfirms that I. nipponensis parasitizes the endangered leopard cat P. bengalensis euptilura.

Purpose: Preimplantation genetic testing for monogenic disorders (PGT-M) has been successfully used to prevent couples with monogenic disorders from passing them on to their child. Charcot–Marie–Tooth Disease (CMT) is a genetic disorder characterized by progressive extremity muscle degeneration and loss of sensory function. For the first time in Korea, we report our experience of applying single nucleotide polymorphism genotyping and karyomapping for PGT-M of CMT disease. Materials and Methods: Prior to clinical PGT-M, preclinical tests were performed using genotypes of affected families to identify informative single-nucleotide polymorphisms associated with mutant alleles. We performed five cycles of in vitro fertilization PGT-M in four couples with CMT1A, CMT2A, and CMT2S in CHA Fertility Center, Seoul Station. Results: From July 2020 through August 2021, five cycles of PGT-M with karyomapping in four cases with CMT1 and CMT2 were analyzed retrospectively. A total of 17 blastocysts were biopsied and 15 embryos were successfully diagnosed (88.2%). Ten out of 15 embryos were diagnosed as unaffected (66.7%). Five cycles of PGT-M resulted in four transfer cycles, in which four embryos were transferred. Three clinical pregnancies were achieved (75%) and the prenatal diagnosis by amniocentesis for all three women confirmed PGT-M of karyomapping. One woman delivered a healthy baby uneventfully and two pregnancies are currently ongoing. Conclusion: This is the first report in Korea on the application of karyomapping in PGT-M for CMT patients. This study shows that karyomapping is an efficient, reliable and accurate diagnostic method for PGT-M in various types of CMT diseases.

Complex chromosome rearrangements (CCRs) are structural chromosomal rearrangements involving at least three chromosomes and more than two breakpoints. CCR carriers are generally phenotypically normal but related to higher risk of recurrent miscarriage and having abnormal offspring with congenital anomalies. However, most of CCR carriers are not aware of their condition until genetic analysis of either abortus or affected baby or parental karyotyping is performed. Herein, we present the case that CCR carrier patients can be identified by preimplantation genetic testing of preimplantation embryos. An infertile male patient with severe oligoasthenoteratozoospermia was diagnosed balanced reciprocal translocation, 46,XY,t(3;11) (p26;p14) at first. After attempting the first preimplantation genetic testing for structural rearrangement (PGT-SR) cycle, we found the recurrent segmental gain or loss on 21q21.3-q22.3 of five out of nine embryos. As a result of karyotype re-analysis, the patient’s karyotype showed a balanced CCR involving chromosomes 3, 11, and 21 with three breakpoints 3p26, 11p14, and 21q21. The patient underwent two PGT-SR cycles, and a pregnancy was established after the transfer of an euploid embryo in the second cycle. Amniocentesis confirmed that the baby carried normal karyotype without mosaicism. At 37 weeks gestation, a healthy girl weighting 3,050 g was born.
