概括
抗CD74免疫球蛋白A (IgA) 在患有Modic变化 (MC) 的患者中没有升高,这是腰部疼痛的常见原因. 这一发现表明,抗CD74IgA可能不是区分MC和轴性脊柱关节炎的有用生物标志物.
科学领域:
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
- 放射学 放射学是一门学科.
背景情况:
- 慢性腰部疼痛是轴性脊柱关节炎 (axSpA) 和退行性脊髓疾病的常见症状,在MRI上有Modic变化 (MC).
- 区分早期的axSpA与MC可能具有挑战性,特别是如果没有圣关节的参与.
- 需要诊断血清生物标志物来区分这些条件在模两可的情况下.
研究的目的:
- 为了调查潜在的axSpA生物标志物抗CD74免疫球蛋白A (IgA) 是否在Modic变化 (MC) 的患者中升高.
- 评估抗CD74 IgA作为诊断工具的实用性,以区分MC和axSpA.
主要方法:
- 包括从NFBC1966队列中具有和没有Modic变化的参与者 (MC).
- 使用商业套件测量了抗CD74IgA水平.
- 用对BMI,性别,CRP和腰部疼痛进行调整的线性回归分析来评估MC和抗CD74IGA之间的关联.
主要成果:
- 该研究包括307名参与者 (148名MC,159名没有MC).
- 在对混因素进行调整后,没有发现Modic变化 (MC) 和抗CD74IgA水平之间的关联.
- 没有任何患有MC的参与者表现出高于15U/ml的抗CD74IgA.
结论:
- 抗CD74免疫球蛋白A (IgA) 水平在Modic变化 (MC) 患者中没有升高.
- 在不清楚的情况下,抗CD74 IgA似乎不是区分MC和axSpA的有用生物标志物.
- 需要进一步研究直接比较axSpA和MC患者,以确认抗CD74IGA的诊断潜力.

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Waterproofing and Anti-Bacterial Admixtures in Concrete
244
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Radical Anti-Markovnikov Addition to Alkenes: Mechanism
4.8K
The reaction of hydrogen bromide with alkenes in the presence of hydroperoxides or peroxides proceeds via anti-Markovnikov addition. The radical chain reaction comprises initiation, propagation, and termination steps.
The mechanism starts with chain initiation, which involves two steps. In the first chain initiation step, a weak peroxide bond is homolytically cleaved upon mild heating to form two alkoxy radicals. In the second initiation step, a hydrogen atom is abstracted by the alkoxy...

Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
7.5K
Diols are compounds with two hydroxyl groups. In addition to syn dihydroxylation, diols can also be synthesized through the process of anti dihydroxylation. The process involves treating an alkene with a peroxycarboxylic acid to form an epoxide. Epoxides are highly strained three-membered rings with oxygen and two carbons occupying the corners of an equilateral triangle. This step is followed by ring-opening of the epoxide in the presence of an aqueous acid to give a trans diol.

Radical Anti-Markovnikov Addition to Alkenes: Thermodynamics
2.7K
The anti-Markovnikov addition of hydrogen halides to an alkene is thermodynamically feasible only with HBr. The radical addition reaction with other hydrogen halides like HCl and HI is thermodynamically unfavorable.
