神经学神经学
在瘤学瘤学.
肺部病理学肺部病理学

背景情况:

脑膜瘤是常见的原发性脑瘤,大多是良性,但可以转移,特别是在肺部.
尽管有分子进步,但预测转移潜力仍然具有挑战性.
胸部扩散,包括肺部,胸中和胸的参与,是最常见的额外体表现.

研究的目的:

报告了三起与胸部转移有关的脑膜瘤的不同病例.
为了说明脑膜瘤转移的各种生物轨迹和临床过程.
突出诊断方式和脑膜瘤转移的风险因素.

主要方法:

对三个患有脑膜瘤和胸腔转移的患者的病例报告分析.
诊断确认使用内支气管超声波-跨支气管针吸收 (EBUS-TBNA),皮肤肺活检和机器人辅助支气管镜检查.
分子分析包括BAP1和NF2状态评估.

主要成果:

三个病例呈现了不同的临床过程:一个复发的WHO级1脑膜瘤与BAP1突变和肺病变,一个新的WHO级3脑膜瘤与肺结节,和一个复发的脑膜瘤与双边肺转移.
转移风险与较高的瘤等级,复发和分子变化 (BAP1损失,NF2不活化) 相相关.
最少侵入性支气管镜技术提供了准确和安全的诊断.

结论:

胸膜瘤转移是罕见的,但与侵略性特征和特定的分子形状有关.
延迟期根据瘤等级和分子状况而有很大差异.
综合分子诊断和先进的支气管镜技术对于改善识别和管理至关重要.

Interslice Magnetization Transfer Ratio Imaging for Meningioma Detection

Begin with a patient with meningioma, or a brain tumor, positioned in an MRI scanner for non-invasive brain imaging.Adjust the scanner to obtain structural images of individual slices of the brain.Enhance the contrast to improve tissue differentiation.Use interslice magnetization transfer ratio imaging on brain slices using radiofrequency pulses slightly offset from the MRI signal.The pulses deliver energy to the proton pool in macromolecules and bound water molecules.This energy transfers to...

Ultrasound Imaging of the Thoracic and Abdominal Aorta in Mice to Determine Aneurysm Dimensions

Ultrasound imaging has become a common modality to determine the luminal dimensions of thoracic and abdominal aortic aneurysms in mice. This protocol describes the procedure to acquire reliable and reproducible two-dimensional ultrasound images of the ascending and abdominal aorta in...

Spreading of Chromatin Modifications

Spreading of Chromatin Modifications

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Many animal experiments rely on final data collection time points that are gathered from the harvesting and testing of organs and tissues. The use of appropriate methods for the collection of organs and tissues can impact the quality of the samples and the analysis of the data that is gleaned for the testing of the tissues. The method of euthanasia of the animal can also impact the quality of...
