- 与镜头相关的参数越来越多地被认为是它们在前段形态学中的作用.
研究的目的:
- 在PACD患者中调查 iridotrabecular contact (ITC) 指数和前段参数之间的关联.
- 具体评估镜头相关参数,如相对镜头,对ITC的影响.
- 用扫描源前段光学连贯断层扫描 (AS-OCT) 来识别检测显著ITC的关键参数.
主要方法:
- 对119名接受扫描来源AS-OCT的PACD患者的回顾性分析.
- 手动检查AS-OCT图像以确定ITC指数和相对镜头.
- 接收器操作特征 (ROC) 曲线分析和决策树分析以确定影响因素.
主要成果:
- 在相对镜头和ITC指数 (r=0.451,p<0.001) 之间发现了显著的正相关性.
- 高镜头立与更高的ITC指数 (p<0.001) 有显著的关联.
- 在500μm (ARA 500) 的角度隙区域显示了检测ITC指数≥50%的最高诊断精度 (AUROC=0.983),相对镜头顶没有提高这个精度.
结论:
- 相对镜头密度与PACD中的ITC指数有显著的相关性.

Contact Angle
18.3K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Angle Closure Glaucoma: Treatment
1.2K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
1.1K
Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Factors Influencing Drug Absorption: Disease States and Pharmacology
1.3K
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...

Contact-dependent Signaling
46.9K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
1.2K
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.
