On 13 June 2021, a video was recorded showing an adult female Asian Koel Eudynamys scolopaceus removing three Elliot's Laughingthrush Trochalopteron elliotii nestlings from a nest in a thicket on the banks of Liqiu River in Xinduqiao Town, Kangding, Sichuan, Southwestern China. This is the first record of an Asian Koel removing nestlings from a potential host's nest. Of the various brood parasitism hypotheses, this behavior is most consistent with the farming hypothesis, further suggesting that farming behavior may be a common strategy used by obligate brood parasites.

To identify the spectrum and prevalence of thirteen causative genes mutations in congenital hypothyroidism (CH) patients, we collected blood samples and extracted genomic DNA of 106 CH patients, and designed a customized targeted next-generation sequencing panel containing 13 CH-causing genes to detect mutations. A total of 132 mutations were identified in 65.09% of patients (69/106) on the following nine genes: DUOX2, TG, TPO, TSHR, TTF1, TTF2, NKX2-5, PAX8 and GNAS. 69.70% (92/132) mutations related to thyroid dyshormonogenesis genes, including DUOX2 (n = 49), TG (n = 35), and TPO (n = 8). 21.21% (28/132) mutations related to thyroid dysgenesis genes, including TSHR (n = 19), TTF1 (n = 5), TTF2 (n = 1), PAX8 (n = 2), and NKX2-5 (n = 1). 9.09% (12/132) mutations related to GNAS, which was associated with thyrotropin resistance. No mutation of THRA, TSHB, IYD or SLC5A5 was detected. Among 69 mutations detected patients, 41 (59.42%) patients were two or more mutations detected, and mutations of 30 (43.48%) patients related to two or three genes. According to the pathomechanism of the mutant genes, 57.97% CH patients were classified as thyroid dyshormonogenesis. Overall, DUOX2, TG and TSHR mutations were the most common genetic defects in Chinese CH patients, and thyroid dyshormonogenesis could be the first genetic etiology of CH in Chinese. Besides, multiple mutations accounts for a part of genetic pathogenesis.

To assess the effect of milk on the development of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors, 48 female Sprague-Dawley rats treated with DMBA were divided into 3 groups and given 1 of 3 test solutions for 20 weeks as their drinking liquid: milk, estrone sulfate solution or tap water. The milk group showed a significantly great incidence (75%) in tumor development compared with the water group (38%) and was comparable to the estrone sulfate group (69%). Mean tumor number per rat in the milk group was significantly higher than that in the water group (p=0.009). We classified the mammary tumors into three histological types: intraductal papilloma, fibroadenoma, and adenocarcinoma. Although the percent of intraductal papilloma and fibroadenoma was almost same among the three groups, malignant tumor was found only in the milk and estrone sulfate groups. In conclusion, our results indicate that milk as well as estrone sulfate promotes the development of DMBA-induced mammary tumors in rat and could be associated with the occurrence of adenocarcinoma.
