概括
血清阴性类风湿性关节炎 (SNRA) 是多样化的,一些患者经历了显著的关节损伤. 除了类风湿因子 (RF) 和抗素化抗体 (ACPA),新的抗体标是理解和管理SNRA的关键.
科学领域:
- 类风湿病学 类风湿病学

背景情况:
- 血清阴性类风湿性关节炎 (SNRA) 占风湿性关节炎 (RA) 病例的20-30%.
- 以前认为较温和,SNRA现在被认为是异质的,一些患者表现出显著的结构性进展.
- 标准的RF和ACPA测试可能会错过SNRA患者的非传统自身免疫反应,正如更广泛的抗改蛋白抗体 (AMPA) 家族所表明的那样.
研究的目的:
- 审查关于SNRA流行病学,免疫病理学,诊断和治疗的当前知识.
- 要强调侵蚀性和非侵蚀性SNRA表型之间的区别.
- 探索AMPA范式对理解SNRA的影响.

The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

A conservative force, such as a gravitational or elastic force, gives the body the capacity to do work. This capacity, measured as the potential energy, depends on the body's location or “position” relative to a fixed reference position or datum. The gravitational potential energy is considered zero at the reference point. Suppose a body is located at some vertical distance above a fixed horizontal reference or datum. In that case, the weight of the body has positive gravitational potential...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...

Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...
