| 1 | Duodenal mature teratoma causing partial intestinal obstruction:A first case report in an adult显示文摘BACKGROUND A teratoma is a germ cell tumor that is composed of tissue derived from two or three germ layers.Duodenal teratomas are extremely rare and have been exclusively reported in neonates and children.This is the third case of a teratoma primarily arising in the duodenum and the first case that occurred in an adult.CASE SUMMARY A 31-year-old male presented with clinical partial gut obstruction(epigastric pain,nausea,and vomiting).The physical examination showed a palpable illdefined mass on the left side of the abdomen.The computed tomography scan revealed a multiseptated cystic tumor at the retroperitoneal area.First,he underwent gastrojejunostomy to relieve the symptoms and was referred to a tertiary-care hospital.The second operation revealed a 10-cm solid-cystic mass originating from the third part of the duodenum and adhering to the abdominal aorta and pancreas.Segmental duodenectomy was performed.The pathological diagnosis was a mature cystic teratoma.The patient was asymptomatic at 5 mo after the operation.CONCLUSION Duodenal teratomas are extremely rare but should be included in the differential diagnosis in patients who present with intestinal obstruction.Radiological imaging is helpful to reach the preoperative diagnosis.Multidisciplinary team planning is essential to avoid injury to the adjacent organ in duodenal operation. | Tharintorn Chansoon Napat Angkathunyakul Rangsima Aroonroch Jakrapan Jirasiritham | 2020 | World Journal of Clinical Cases2020，8，8： | 1 |

| 3 | Effect of Incubation Temperature on the Somatic Development of the Snail-Eating Turtle Malayemys macrocephala显示文摘The rising average global temperature can lead to changes both in the physical and biological environments and affect the survival of organisms. Freshwater turtles are considered to be susceptible species since their development is dependent on incubation temperature. In Thailand, although several species of freshwater turtle are present, the extent of their susceptibility to temperature change is unknown due to the lack of information on their developmental patterns. This research, therefore, is aimed at examining the effects of temperature on somatic development in Malayemys macrocephala, a native species and the most common freshwater turtle in Thailand. Turtle eggs were collected from rice fields in the central part of Thailand during December 2011 to February 2012 inclusive. Eggs(237–238 per condition) were incubated in microprocessor-controlled incubators at three different temperatures(26 °C, 29 °C and 32 °C) with a relative humidity in excess of 80%. Each week, until the remaining eggs hatched, eggs were randomly selected, removed and dissected to reveal the developing embryo to screen for developmental stage and any abnormalities. The incubation period(lay to hatch) was not significantly different among the three temperatures(115 ± 11.3 d, 115 ± 20.3 d and 109 ± 17.8 d, respectively), but the growth patterns, as indicated by the stages of development and carapace lengths, were significantly different. At a high temperature(32 °C), turtle embryos showed a significantly faster growth rate than at the intermediate and low temperatures(29 °C and 26 °C), but had a significantly(over 3.3-fold) higher incidence of developmental abnormalities(especially deformed bodies) than at the lower temperatures. Overall, the results indicate that incubation temperature is an important variable affecting the somatic development of this tropical freshwater turtle species, whilst abnormalities in the embryonic body may be a sensitive indicator of extreme thermal stress. | Rangsima PEWPHONG Jirarach KITANA Noppadon KITANA | 2013 | Asian Herpetological Research2013，4，4： | 0 |
| 4 | Thermosensitive period for sex determination of the tropical freshwater turtle Malayemys macrocephala显示文摘Many egg-laying reptiles possess temperature-dependent sex determination(TSD)in which outcome of gonadogenesis is determined by incubation temperature during a temperature-sensitive period of development.Prior studies on Malayemys macrocephala showed that incubation temperatures influence gonadal development and suggested that M.macrocephala exhibits TSD.However,information on the temperature-sensitivity period in this species was unknown until the current study.Turtle eggs were collected from rice fields in central Thailand from December 2016 to February 2017.In the laboratory,eggs were incubated at male-biased temperature(26°C)and shifted to female-biased temperature(32°C),or vice versa.Single shift experiments were performed systematically during embryonic stages 13–21.After hatching,sex of individual turtles was determined by histological analysis.We found that the sex determination of M.macrocephala is affected by temperature up to stage 16 of embryonic development. | Rangsima PEWPHONG Jirarach KITANA Noppadon KITANA | 2021 | Integrative Zoology2021，16，2： | 0 |
