概括
与拉布拉多犬相比,拳击犬在骨平整骨切除术 (TPLO) 后的骨愈合速度较慢. 放射性评分系统可靠地评估了愈合,较大的初始骨切除间隙表明结果较差.
科学领域:
- 兽医整形医学 兽医整形医学
- 手术结果研究研究.
- 狗的比较解剖学 狗的比较解剖学
背景情况:
- 骨平衡骨切除术 (TPLO) 是一种常见的治疗犬交叉带疾病的程序.
- 评估TPLO后的骨愈合对于预测功能恢复至关重要.
- 品种特定的愈合特征和客观评分方法需要进一步调查.
研究的目的:
- 为了比较5点和10点放射性评分系统在TPLO后评估骨愈合的有效性.
- 为了确定与年龄相匹配的拉布拉多犬相比,拳击犬是否表现出不同的骨切除术愈合时间.
主要方法:
- 多中心回顾性研究涉及58只客户拥有的狗 (29只拳击手,29只拉布拉多犬) 接受TPLO.
- 术后大约8周拍摄的放射图由五位经过董事会认证的外科医生使用5分和10分评分系统进行评估.
- 最初的术后放射图被评估是否存在骨切割间隙 (≥1毫米).
主要成果:
- 五分和十分评分系统都表现出良好的观察者间和观察者内部的一致性.
- 与拉布拉多犬相比,拳击犬在TPLO后8周的放射性骨愈合得分明显较低 (p ≤ 0.001).
- 术后骨切除间隙 (≥1毫米) 的存在与两种品种的愈合得分较低显著相关 (p < 0.001).
结论:
- 在5分和10分评分系统之间,观察者变异性没有显著差异.
- 与拉布拉多犬相比,拳击犬在TPLO后8周的放射性骨愈合速度较慢.
- 术后骨切除术间隔≥1毫米是TPLO后骨愈合的负面预后指标.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
