Background : Traditional DNA microinjection methods used in mammals are difficult to apply to avian species due to their unique reproductive characteristics. Genetic manipulation in chickens, particularly involving immature follicles within living ovaries, has not been extensively explored. This study seeks to establish an efficient method for generating transgenic chickens through ovarian injection, potentially bypassing the challenges associated with primordial germ cell (PGC) manipulation and fertilized egg microinjection. Methods : Hens were anesthetized and underwent a surgical procedure to access the ovary for DNA injection into immature follicles. The study used liposomes to deliver GFP- expressing plasmids at various dosages. After injection, hens recovered, and their eggs were fertilized through artificial insemination. Results : Transgenic chickens were successfully generated in one generation without needing G0 founders. The injection of 20 μg plasmid yielded the highest transgenic efficiency at 12.1%. GFP- positive embryos were confirmed through microscopy, and successful transgene expression was validated at the tissue level using immunostaining. TERT and GFP elements introduced in the G1 generation resulted in 4.1% positive transgene rates, as confirmed by PCR and Southern blotting. Conclusion : This ovarian injection method offers a promising alternative for avian genetic manipulation, bypassing complex PGC procedures and enabling direct generation of G1 transgenic chickens. This technique simplifies the transgenic process for chickens and has the potential to be adapted for other avian species, especially those without established PGCs culture systems.

Journal of Palaeogeography 2025年第01期14卷 291-313页

作者： Peng Sun Hai-Feng Yang fei-Long Wang Jun-Pei Yue Yan-fei gao You-Jun Tang School of Petroleum Engineering Yangtze University Key Laboratory of Exploration Technologies for Oil and Gas Resources Ministry of Education Yangtze University Tianjin Branch of China National Offshore Oil Corporation College of Resource and Environment Yangtze University

The Member 4 of the Paleogene Shahejie Formation(Es4) in the Bohai Bay Basin is interspersed with a set of high-quality source rocks typified as intercalation of red and black mudstones. A large amount of petroleum(crude oil) originates from these source rocks. The Paleocene-Eocene Thermal Maximum(PETM)event occurred during the deposition of Es4 in the Bohai Bay Basin, and the organic matter enrichment model under this event is worth further investigation due to its relationship with and influence on petroleum accumulations. Well LK25-A, as the first oil exploration well drilled into the Es4 in Miaoxi area, serves as a valuable case to study organic matter accumulation. In this study, we integrate total organic carbon(TOC),Rock-Eval pyrolysis, microscopic observation, vitrinite reflectance(VRo), elemental analysis, and gas chromatography-mass spectrometry(GC-MS) to evaluate the hydrocarbon generation potential, organic matter types, thermal maturity, and sedimentary environment of the Es4 in Miaoxi area. The analysis of maceral and rock pyrolysis data reveals that Type I and Type II organic matter make up the majority of Paleogene mudstones in this region. The TOC and rock pyrolysis data show that mudstones in this area have high organic matter abundance and oil-generation potential. The measured vitrinite reflectance distribution of mudstone samples, which ranges from 0.3% to 0.74%, demonstrates that the Paleogene strata are at the immature to mature stage, and the samples from this area contain a sizable amount of bituminite and mineralbituminous groundmass. The analysis of biomarkers in the mudstone samples indicates that most of the mudstones in this area are in lacustrine and brackish-hypersaline lacustrine environment under a reducing condition, and some of the red mudstones in the Es4 are formed under a suboxic condition. Based on the size and morphology of the pyrite framboid, the redox conditions of the water mass during deposition or diagenesis are further

农村集体经济组织成员退出农村集体经济组织丧失成员身份,将不再享有成员权。基于农村集体所有权是农村集体所有制的法律实现形式,农村集体经济组织是农村集体所有权的实现主体,农村集体经济组织成员是农村集体财产利益的最终享有者,《农村集体经济组织法》确立了农村集体经济组织成员退出补偿规则。《农村集体经济组织法》中农村集体经济组织成员退出补偿规则的内容较为粗略,以致在补偿标准、补偿方式、补偿决策制度和成员退出的风险防范等方面均面临实践的挑战,应当系统解读其中与成员退出相关的法律规范,确立成员退出的补偿标准,明晰成员退出的补偿方式,细化成员退出补偿方案的民主决策制度,建立成员退出补偿规则实施的风险防范机制,以化解成员退出补偿的实践难题。

基于陕西省在“第三次全国农作物种质资源普查与收集行动”中获得的农民认知和普查数据,对收集筛选的优异资源进行分析,发现陕西省优异资源的作物种类以常见大宗作物为主,其中蔬菜、果树最多,粮食作物次之,表现为以品质优、外观好、适应性强为主,其次是外部性状和抗性性状,且口味是农民最关注的品质性状;作物分布特点为关中地区蔬菜、果树较多,陕南地区粮食作物较多,且作物分布受自然和人文环境双重影响。农民认知能真实反应农民的主观需求、选择方向以及选择驯化策略或经验,优质是农民留存资源的主因,其次是外观和适应性,且选择方向是以解决突出问题为主,兼顾其他需求,从而导致主要需求及其对应的主要优异性状与次要需求及其对应的优异性状具有较大相关性,人工选择痕迹明显。因此,陕西省优异资源受自然环境影响的同时,人工选择使其更加丰富多彩。陕西省优异资源保护利用工作应充分考虑资源分布特点,以资源价值发掘为重心,通过建立合理的利益机制和管理机制,逐步完善资源保护利用体系。

BACKGROUND Colorectal cancer (CRC) is one of the most common malignant gastrointestinal tumors worldwide, with high incidence and mortality rates. AIM To investigate the expression significance of the chromatin-remodeling protein MORC family CW-type zinc finger 4 (MORC4) as a biomarker in CRC patients, and to explore its relationship with pathological features and prognosis. METHODS A total of 143 CRC specimens and 57 adjacent tissue specimens, surgically removed from our hospital between January 2020 and January 2021, were collected. MORC4 protein expression was assessed using immunohistochemistry after paraffin embedding. The relationship between MORC4 protein expression and clinicopathological characteristics of patients was analyzed. Kaplan-Meier survival curves were plotted to analyze the relationship between MORC4 protein expression and prognosis in CRC patients. RESULTS Compared with adjacent tissues, the expression rate of MORC4 protein in CRC tissues was significantly higher (P 0.05). However, significant differences were found in the high expression rate of MORC4 protein in patients with different degrees of differentiation, lymph node metastasis, distant metastasis, tumor-lymph node-metastasis stage, and serum carcinoembryonic antigen levels (P < 0.05). Compared with patients with low MORC4 expression, patients with high MORC4 expression had a worse prognosis (P < 0.05). CONCLUSION The upregulation of MORC4 expression in CRC patients is closely related to disease severity and prognosis, suggesting its potential as an evaluation biomarker, which warrants further investigation. © The Author(s) 2025.
