概括
在面外科手术中,皮佐托姆辅助削 (PR) 改变了早期的骨愈合表面,但与手动削 (MR) 相比,它不会阻碍长期的骨再生. 这支持在鼻美术中使用皮埃佐托姆.
科学领域:
- 生物医学工程 生物医学工程
- 口腔和牙面部外科手术
- 再生医学是一种再生医学.
背景情况:
- 截肢手术提供精确的骨切割与减少软组织创伤在面手术.
- 皮埃索外科手术在削过程中对骨愈合的影响尚不清楚.
研究的目的:
- 为了比较手动削 (MR) 后的骨再生与羊模型中鼻骨的 piezotome 辅助削 (PR).
- 评估早期和晚期的组织学结果和骨质生成.
主要方法:
- 在骨成熟的绵羊的鼻骨上产生了双边缺陷.
- 一侧接受了皮埃佐托姆辅助削 (PR),另一侧手动削 (MR).
- 术后3周和12周进行了组织学分析.
主要成果:
- 在3周后,PR缺陷显示了微裂的不规则边缘,而MR缺陷具有更光滑的边缘.
- 到了12周,这两种技术都显示出相似的骨再生,结构成熟,没有炎症.
- 半定量骨质生成得分在两个时间点在MR和PR之间统计上是相似的.

Predicting Reaction Outcomes
10.3K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis
106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Spongy Bone
7.6K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Compact Bone
16.2K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
