CRISPR/Cas: a Nobel Prize award-winning precise genome editing technology for gene therapy and crop improvement

Since it was first recognized in bacteria and archaea as a mechanism for innate viral immunity in the early 2010 s,clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein(Cas) has rapidly been developed into a robust, multifunctional genome editing tool with many uses. Following the discovery of the initial CRISPR/Cas-based system, the technology has been advanced to facilitate a multitude of different functions. These include development as a base editor, prime editor, epigenetic editor, and CRISPR interference(CRISPRi) and CRISPR activator(CRISPRa) gene regulators. It can also be used for chromatin and RNA targeting and imaging. Its applications have proved revolutionary across numerous biological fields, especially in biomedical and agricultural improvement. As a diagnostic tool, CRISPR has been developed to aid the detection and screening of both human and plant diseases, and has even been applied during the current coronavirus disease 2019(COVID-19) pandemic. CRISPR/Cas is also being trialed as a new form of gene therapy for treating various human diseases, including cancers, and has aided drug development. In terms of agricultural breeding, precise targeting of biological pathways via CRISPR/Cas has been key to regulating molecular biosynthesis and allowing modification of proteins, starch, oil, and other functional components for crop improvement. Adding to this, CRISPR/Cas has been shown capable of significantly enhancing both plant tolerance to environmental stresses and overall crop yield via the targeting of various agronomically important gene regulators. Looking to the future, increasing the efficiency and precision of CRISPR/Cas delivery systems and limiting off-target activity are two major challenges for wider application of the technology. This review provides an in-depth overview of current CRISPR development, including the advantages and disadvantages of the technology,recent applications, and future considerations.     

肉鸡猝死的病因分析与防制措施

1肉鸡猝死综合症的临床诊断1.1临床症状本病多发生于3—5周龄的雏鸡。患病鸡突然发病,平衡失调,两翅猛烈扑打,肌肉强痉挛,尖叫翻滚,呈仰卧姿势,头颈扭曲而亡。从发病到死亡经过不足一分钟。多发于生长快、外表健康、体状良好的鸡只。1.2病理变化对患病死亡后的鸡只剖检,发现冠髯和泄殖粘膜及脾脏充血,全身肌肉苍白,消化道内充满食物,肝脏肿大、质地易碎;肺肿大,弥漫淤血水肿,呈暗红色,气管内有泡沫状渗出物;心脏明显增大2—4倍,心肌松软,心包渗出液增多,静脉怒张。采集病料进行微生物培养阴性。1.3鉴别诊断本病与澳大利亚报道的肉鸡峰型死亡…     

苹果白粉病发生特点及药剂防治技术初探

通过对苹果白粉病4～5月份发病情况的田间调查,结果表明:苹果白粉病在4～9月为病害发生期,其中 4～5月气温较低,枝梢组织幼嫩,为白粉病发生盛期,对果树的中后期生长发育影响极大。6～8月发病缓慢或停滞。杀菌剂防治苹果白粉病的田间试验结果表明:4月中旬病害发生初期开始喷药,一般防效可达80％左右。喷药3～4 次,间隔10～15 d左右喷药一次。在使用药剂防治苹果白粉病时,不论是保护性杀菌剂还是治疗性杀菌剂,都应坚持轮换用药的原则。此外,在使用药剂防治该病的同时,还应辅以花期人工摘除,结合冬剪,剪除破芽,压低病原基数等农业技术措施进行防治。     

幼儿对疾病相关概念的认知

本研究主要采用访谈法,考察了300名45～80个月的幼儿对10个疾病相关概念的认知,结果表明幼儿主要以具体举例和直观特征形式定义概念,并表现出一定的年龄差异、性别差异和园所差异。在幼儿园健康教育中,应培养幼儿正视疾病的态度;应根据幼儿当前认知,不断丰富幼儿疾病相关知识;既应关注幼儿健康行为的养成,又应注重健康教育的科学性,同时要积极利用幼儿将疾病发生视为行为后果的认知特点,培养其关注自身和他人健康的主体意识。     

血浆纤维蛋白原含量升高与冠心病

用盐析－双缩脲法对９７例健康人和７９例冠心病患者进行了血浆纤维蛋白原含量的测定，结果表明：冠心病患者血浆纤维蛋白原含量显著高于健康人（Ｐ＜０．０１），提示纤维蛋白原含量升高是冠心病、中风、血栓形成的一种重要的危险因素．对血浆纤维蛋白原进行检测，将为冠心病的临床诊断及预防提供依据     

教师运动习惯与健康保健研究

对教师常见病问题进行问卷调查,发现教师的颈椎病、心脑血管病、神经衰弱、肠胃病、痔疮最为常见,且不同教学年限教师、坚持长期运动与没有运动习惯的教师,他们的身体状况差异很大。教师的常见病与他们和教学年限和运动习惯存在相关关系。
