概括
基底细胞癌 (BCC) 中的流体边缘参与很少导致复发,特别是在非表面亚型中. 管理可以更有选择性,避免在没有表面组件的情况下对BCC进行例行重新切割.
科学领域:
- 皮肤病学 皮肤病学
- 在瘤学瘤学.
- 手术病理学手术病理学
背景情况:
- 基底细胞癌 (BCC) 相关的肌瘤对组织学边缘的影响具有不确定的临床意义.
- 了解残留疾病风险对于优化BCC管理策略至关重要.
研究的目的:
- 为了确定在再切割标本中的残留BCC的发生率.
- 评估在不进行再切割的情况下管理的BCC病例中的临床复发率,当涉及筋膜边缘时.
主要方法:
- 追溯审查58个BCC病例,其中包括 stromal边缘 (2016-2020年).
- 分析了50例接受立即再切割的病例和8例在临床观察下管理的病例.
- 按BCC组织学亚型和树叶边缘参与 (外围,深层或两者兼而有之) 进行分类.
主要成果:
- 在8%的重新切除病例中 (4/50),仅在具有表面成分的瘤中发现了残留性癌症.
- 在经过再切割的结节性或透性BCC中没有观察到残留癌症.
- 总体残留或复发性疾病发生在7%的病例中 (4/58),结果因组织学亚型而异.
结论:
- 在非表面的BCC中,流体边缘参与具有较低的残留或复发疾病风险.

Residual Stresses
604
Residual stresses reside in a structure even after removing the original stress inducer. This phenomenon often arises from varied plastic deformations across different parts of a structure. Consider a rod stretched beyond its yield point. It will not regain its original length due to permanent deformation. Even after load removal, the rod does not entirely lose stress because of uneven plastic deformations, resulting in residual stresses. The computation of these stresses in structures is...

Residual Plots
6.2K
A residual plot is a statistical representation of data used to analyze correlation and regression results. It helps verify the requirements for drawing specific conclusions about correlation and regression. To obtain the residual plot, first, the residual for each data value is calculated, which is simply the vertical distance between the observed and the predicted value obtained from the regression equation.
When the residual values are plotted against the variable x, it is called a residual...

Protein Transport to the Stroma
2.2K
Chloroplasts are triple membrane structures with an outer membrane, an inner membrane, and a thylakoid membrane, each containing distinct metabolite transporters, membrane translocons, and enzymes. Appropriate sorting and translocating these proteins to their correct membrane systems is essential for chloroplast function.
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...

Margin of Error
7.1K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Residual Stresses in Circular Shafts
523
In materials that exhibit elastic and plastic behavior, known as elastoplastic materials, residual stresses can accumulate when these materials experience plastic deformation. This deformation arises from either high levels of shearing stress or significant strains. Residual stresses are internal stresses that persist within a material after removing the external force causing deformation. This phenomenon is demonstrated when observing the behavior of a shaft under torque; notably, the...

Laminins are the Adhesive Proteins of Basal Lamina
3.1K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...
