ObjectiveTo explore the regulatory effect of Pien Tze Huang (PZH) on targeting partner of NOB1 (PNO1) and it’s down-stream mediators in colorectal cancer (CRC) *** polymerase chain reaction was performed to determine mRNA levels of PNO1, TP53, and CDKN1A. Western blotting was performed to determine protein levels of PNO1, p53, and p21. HCT-8 cells were transduced with a lentivirus over-expressing PNO1. Colony formation assay was used to detect cell survival in PNO1 overexpression of HCT-8 cells after PZH treatment. Cell-cycle distribution, cell viability and cell apoptosis were performed to identify the effect of PNO1 overexpression on cell proliferation and apoptosis of HCT-8 cells after PZH treatment. Xenograft BALB/c nude mice bearing HCT116 cells transduced with sh-PNO1 or sh-Ctrl lentivirus were evaluated. Western blot assay was performed to detect PNO1, p53, p21 and PCNA expression in tumor sections. Terminal deoxynucleotidyl transferase dUTP nick end labling (TUNEL) assay was used to determine the apoptotic cells in *** treatment decreased cell viability, down-regulated PNO1 expression, and up-regulated p53 and p21 expressions in HCT-8 cells (P<0.05). PNO1 overexpression attenuated the effects of PZH treatment, including the expression of p53 and p21, cell growth, cell viability, cell cycle arrest and cell apoptosis in vitro (P<0.05). PNO1 knockdown eliminated the effects of PZH treatment on tumor growth, inhibiting cell proliferation inhibition and apoptosis induction in vivo (P<0.05). Similarly, PNO1 knockdown attenuated the effects of PZH treatment on the down-regulation of PNO1 and up-regulation of p53 and p21 in vivo (P<0.05).ConclusionThe mechanism by which PZH induces its CRC anti-proliferative effect is at least in part by regulating the expression of PNO1 and its downstream targets p53 and p21.

中生代鸟类的食性推断往往依赖于传统的形态对比和直接的化石证据,但不完整的化石记录和特异埋藏的稀缺性使得我们需要寻找更多有用特征和方法来对化石鸟类进行食性评估。鸟类颈部结构是一个高度模块化、形态和功能密切关联的系统;在恐龙向鸟类演化的过程中,前肢由于飞行适应独立出来,使得颈部需要更多地帮助鸟类实现捕食及其他生态功能。因此,颈部有可能成为鸟类食性推断的显著特征之一。利用形态测定和统计分析,建立起现生鸟类和中生代灭绝鸟类的颈椎形态和食性模式之间的量化关系。基于现生鸟类构建了形态-功能框架,评估了早白垩世热河生物群中发现的5种鸟类的食性模式。结果表明,颈椎形态分异与鸟类取食多样性量化相关,3种反鸟表现出了食虫或食肉鸟类的颈椎形态特征,两种今鸟型类则表现出杂食性或植食性,以及原始的水生适应形态特征。新的分析结果与之前发现的化石直接证据以及其他相关的形态研究基本一致,因此,颈椎作为与取食功能密切相关的骨骼系统,可以为中生代鸟类取食生态的推断提供一定信息。

Evaluation of Growth Rate of Invasive Aquatic Macrophytes and Contribution to Its Use in Organic Fertilizer Production: A Case of Eicchornia crassipes (Mart.) Solms, 1883 in the Lobé Creek (Littoral-Cameroon)

引用

Open Journal of Ecology 2024年第7期14卷 571-583页

作者： Roland Didier Nwamo Gordon Nwutih Ajonina Tapite Chanel Yamkou Kopmou thomas Efole Ewoukem Minette Tomedi Eyango Department of Aquatic Ecosystems Management Institute of Fisheries and Aquatic Sciences at Yabassi University of Douala Douala Cameroon Cameroon Wildlife Conservation Society Mangrove & Coastal Wetlands Research Centre Mouanko Cameroon Department of Forestry Faculty of Agronomy and Agricultural Sciences University of Dschang Dschang Cameroon Department of Aquaculture Institute of Fisheries and Aquatic Sciences at Yabassi University of Douala Douala Cameroon

From 20 January to 20 July 2023, a study was carried out on the Lobé Creek, a waterway subject to considerable natural and man-made pressures, with a negative impact on its biodiversity and habitats. The aim was to evaluate the growth rate of invasive aquatic macrophytes and their contribution to the use of organic fertilisers: a case of Eicchornia crassipes (Mart.) Solms, 1883 in the Lobé Creek (Littoral-Cameroon) with a view to its appropriate use in agronomy. The specific objective was to examine the impact of anthropogenic actions on Lobé Creek, characterise physico-chemical environment of the study area, and evaluate the growth rate of E. crassipes and its chemical composition with a view to producing an organic biofertiliser. The results show that E. crassipes represents a considerable threat to the populations of these localities. As for the physico-chemical parameters, the temperature values vary from 24 ± 1.41˚C to 26.5 ± 1.13˚C;pH from 6.3 ± 0.1 to 7.2 ± 0.07;conductivity and dissolved oxygen vary respectively from 40.7 ± 1.83 µS/cm to 19.6 ± 3.11 µS/cm and from 7.3 ± 0.14 mg/l to 5.8 ± 1.55 mg/l. Its average growth rate varies from 0.69 feet/day to 0.63 feet/day. With regard to the nitrogen, phosphorus and potassium content of water hyacinth plants, the results show that the average total nitrogen content ranges from 6.11 ± 1.59 g/kg to 5.2 ± 2.03 g/kg;total phosphorus, from 0.52 ± 0.54 g/kg to 0.88 ± 0.38 g/kg;and potassium, from 1.43 ± 0.45 g/kg to 2.61 ± 0.89 g/kg.

The Support Systems and Coping Strategies of Infertile Women Attending the Out-Patient Consultation Unit of CHRACERH Yaoundé, Cameroon: A Cross-Sectional Study

引用

Open Journal of Obstetrics and Gynecology 2024年第6期14卷 869-887页

Background: Infertility is a complex disorder with significant psycho-social and economic consequences. It globally affects 10% - 15% of couples. In Cameroon, little is known about what women do to overcome the psychosocial aspects of the disease. Objectives: This study aimed to identify the support systems and coping strategies of infertile women attending the outpatient consultation unit of the Gynaecological Endoscopic Surgery and Reproductive Teaching Hospital (CHRACERH), Yaoundé, Cameroon. Methods: A hospital-based cross-sectional study was conducted from the 14th of March to the 6th of April 2023 at CHRACERH Yaoundé. A total of 190 participants were recruited using a convenience sampling method. Data regarding socio-demographic characteristics, support systems and coping strategies were collected using a pretested questionnaire. Descriptive and analytic statistics were conducted using SPSS version 25. Results: The mean age of participants was 39.52 ± 7.64 years. The majority 78.9% of participants were workers (public, private sector, or traders) and were Christians 95.8%. The most common source of psychological support was from family 76.8 and husbands 72.63%. Most of the participants 89.5% resorted to prayer and getting busy 48.4% as a coping strategy. There was no statistically significant relationship between coping strategies and psychological disorders p > 0.05. Conclusion: The main support system of participants was family, husband, and friends. Prayer, getting busy and adoption were the most common coping strategies. There is a need for the Ministry of Public Health and other stakeholders to put in place other support systems and coping strategies (FELICIA) used elsewhere and provide adequate health education and infection control to prevent infertility in Cameroon.

盗版电影或电视节目的非法订阅机构每年赚取20亿美元的广告费和订阅费,自从推出流媒体业务与奈飞(Netflix Inc.)展开竞争以来,老牌好莱坞机构一直难以在这个领域盈利,迪士尼+、派拉蒙+和Peacock等公司每年亏损数十亿美元。这引发了华尔街的担忧,即这些流媒体服务永远不会像有线电视曾经那样盈利。但是,流媒体时代却给一些出人意料的赢家带来了福音:盗版者利用软件,几秒钟内就从合法的在线视频平台下载了电影或电视节目,转而在它们的非法服务上播放这些节目,然后这些盗版者每年从广告和订阅中赚取约20亿美元收入。
