背景情况:
- 腰部疼痛 (LBP) 是全球导致残疾的主要原因.
- 腰椎间盘 (LDH) 通常会导致根茎病变,但MRI可能是模两可的.
- 需要客观的生物标志物来区分症状LDH和与年龄相关的变化.
研究的目的:
- 评估核肉 (NP) 的定量T2加权信号强度比 (SIR) 作为LDH分期的客观生物标志物.
- 为了使测量标准化,使用内部参考来进行比较.
- 为了将SIR与症状持续时间相关联.
主要方法:
- 对157名患有MRI确认的LDH和根性症状的患者进行了回顾性分析.
- 与脑脊液 (CSF),前纤维环 (AF) 和相邻的NP相比,性NP的SIR计算.
- 根据症状持续时间分组患者:急性 (<2周),亚急性 (2-4周) 和慢性 (>4周).
- 使用ANOVA和post-hoc测试进行统计分析,对临床变量进行调整.
主要成果:
- 随着症状持续时间的延长,SIRs显著下降 (P<0.001).
- 最强大的时间标记是SIR-NP/CSF,从0.30 (急性) 下降到0.12 (慢性).
- 一个SIR-NP/CSF值<0.20表示亚急性/慢性阶段.

Contact-dependent Signaling
47.6K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Calmodulin-dependent Signaling
6.2K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

NF-κB-dependent Signaling Pathway
10.1K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Chronopharmacokinetics: Time-Dependent Pharmacokinetics
418
Chronopharmacokinetics studies the temporal change in drug absorption and elimination. These changes can be cyclical or non-cyclical. Cyclical changes occur over a regular interval, while non-cyclical changes occur over a longer, irregular period.
Time-dependent pharmacokinetics refers to non-cyclical changes in drug rate processes over a period of time. It can lead to nonlinear pharmacokinetics, where the relationship between drug concentration and time is not proportional. Non-cyclical...

The Integrated Rate Law: The Dependence of Concentration on Time
42.7K
While the differential rate law relates the rate and concentrations of reactants, a second form of rate law called the integrated rate law relates concentrations of reactants and time. Integrated rate laws can be used to determine the amount of reactant or product present after a period of time or to estimate the time required for a reaction to proceed to a certain extent. For example, an integrated rate law helps determine the length of time a radioactive material must be stored for its...

Basic Continuous Time Signals
709
Basic continuous-time signals include the unit step function, unit impulse function, and unit ramp function, collectively referred to as singularity functions. Singularity functions are characterized by discontinuities or discontinuous derivatives.
The unit step function, denoted u(t), is zero for negative time values and one for positive time values, exhibiting a discontinuity at t=0. This function often represents abrupt changes, such as the step voltage introduced when turning a car's...
