概括
在原发性渐进性多发性硬化症 (PPMS) 中,更薄的周状视网膜神经纤维层 (pRNFL) 预测了更快的残疾进展和增加的神经退行. 这一发现支持pRNFL作为PPMS临床试验中的关键生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 眼科医生 眼科 眼科
- 放射学 放射学是一门学科.
背景情况:
- 光学连贯断层扫描 (OCT) 是多发性硬化症 (MS) 中神经退行症的新兴生物标志物.
- 虽然视网膜层厚度预测了复发性多发性硬化症的进展,但其在初级渐进性多发性硬化症 (PPMS) 中的作用尚不清楚.
研究的目的:
- 为了研究是否周状视网膜神经纤维层 (pRNFL) 和质细胞内状层 (GCIPL) 厚度预测残疾进展.
- 确定PRNFL和GCIPL是否预测PPMS患者的视网膜,大脑和脊髓缩 (SCA).
主要方法:
- 一项追溯纵向研究分析了69名PPMS患者的临床,OCT和MRI数据.
- 根据pRNFL和GCIPL厚度对患者进行了分层.
- 线性回归估计了年度稀释率,而回归模型,卡普兰-梅尔和考克斯生存分析评估了结果.
主要成果:
- 较低的pRNFL厚度 (≤87微米) 与较高的扩展残疾状态量表 (EDSS) 分数相关,并增加了确认残疾进展的风险.
- 患有较低PRNFL的患者表现出更快的视网膜稀疏,更大的全脑缩和脊髓缩的增加.
- 该研究发现pRNFL厚度与神经退行症标志物之间存在显著的关联.
结论:
- pRNFL厚度是PPMS中残疾进展的重要预测因素.
- pRNFL作为神经退行的一个有价值的替代标记,与视网膜,大脑和脊髓缩相关.

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression
4.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Spinal Nerves: Plexus II
2.4K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Spinal Nerves: Anatomy
8.8K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

Spinal Nerves: Plexus I
2.8K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
