概括
猪前腿延伸肌在生物机械性质上与人类半肌非常相似,使其成为适合研究的替代物. 其他猪肌显示出显著的差异,限制了它们在生物力学研究中的使用.
科学领域:
- 生物医学工程
- 骨科研究
- 比较生物力学
背景情况:
- 猪肌通常用于生物力学研究,作为人类半肌的替代品.
- 猪肌与人类半肌的可比性以前没有研究过.
研究的目的:
- 将各种猪肌的形态和生物力学特性与人类半肌进行比较.
- 确定最适合用于生物力学研究的猪肌替代物.
主要方法:
- 在人类半和四种猪肌上进行了形态测量 (长度,横截面积) 和生物力学测试 (最大负荷,拉力强度,刚度,弹性模量).
- 使用单轴测试来确定材料的性能.
- 统计分析包括Kruskal-Wallis测试和Dunn的后期测试.
主要成果:
- 人类半肌的拉力强度为38.64MPa,弹性模量为518.27MPa.
- 猪前腿延伸肌的截面面积,拉力强度 (32.26 MPa) 和弹性模量 (550.96 MPa) 相似,但较短.
- 猪后腿延伸具有相似的拉力强度 (38.82 MPa) 和弹性模量 (668.83 MPa),但截面较短.
- 与人类肌相比,猪的后腿和前腿长度,横截面积,拉伸强度和弹性模量有显著差异.
结论:
- 尽管存在形态差异,但猪肌的物质性质与人类半肌基本一致.
- 由于材料和形态特征相似,猪前腿延伸肌是最合适的替代物.
- 猪前腿是最不适合的,因为它们具有显著的形态差异.

Overview
What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
