Aim:
To determine whether elevated high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and erythrocyte sedimentation rate (ESR), as risk factors of symptomatic lumbar osteoarthritis (OA) in estrogen deficiency postmenopausal women.
Methods:
A case-control study was conducted between January and June 2017. The inclusion criteria include post-menopausal women with estrogen deficiency with low back pain. Exclusion criteria were: patients with a history of undergoing bilateral oophorectomy, taking hormonal replacement therapy or corticosteroid, malignancies, and lumbosacral spine trauma. The blood examinations were taken to measure IL-6 level by ELISA, hs-CRP level by spectrophotometry and ESR by modified Westergren method.
Results:
A group of 44 pairs of subjects were divided equally into case and control groups showed that in estrogen deficiency postmenopausal women, an increased level of hs-CRP increased the risk for symptomatic lumbar OA (OR = 2.83, CI95% = 1.065-8.776, p = 0.034). Also, a high level of IL-6 increased the risk of symptomatic lumbar OA (OR = 2.7, CI95% = 0.991-8.320, p = 0.033). No such significant findings were found for an increased ESR level.
Conclusion:
Elevated level of plasma hs-CRP and IL-6 were concluded as risk factors for symptomatic lumbar OA in post-menopausal women.

03:12Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In...
