Salbutamol [HRP]

Objectives:This study compared neurofilament light chain (NFL) levels in the cerebrospinal fluid (CSF) of patients with sporadic amyotrophic lateral sclerosis (sALS) with levels in patients with other neurological diseases and healthy controls and assessed correlations between NFL levels and clinical indicators of sALS. Methods:We used enzyme-linked immunosorbent assays to determine the NFL levels in the CSF of 45 patients with sALS, 21 patients with other central nervous system diseases (OCNSDs), 18 with immune-mediated peripheral neuropathy (IMPN), 14 with non-immune-mediated peripheral neuropathy (NIMPN), and 19 healthy controls (HCs). Results:The median NFL levels in the CSF of the sALS, OCNSD, IMPN, NIMPN, and HC groups were 6510, 5372, 4320, 1477, and 756 pg/mL, respectively. The CSF NFL levels did not differ significantly among the sALS, IMPN, and OCNSD groups, but were significantly higher than those of the NIMPN and HC groups. The NFL CSF levels were significantly higher in the NIMPN group than the HCs. There was a negative correlation between the NFL level and ALS function score (ALSFRS-R), and a positive correlation with the disease progression rate in patients with sALS. Conclusion:CSF NFL may not be sufficient to distinguish ALS from other central nervous system diseases or peripheral neuropathy, but it predicts ALS severity and progression.

Volatile organic compounds, which find uses in industrial processes, need to be replaced to decrease environmental pollution. Ionic liquids (ILs) are promising alternatives in industrial processes involving carboxylic acids. It is thus useful to study the interactions of ILs with organic acids on a laboratory scale. The combination of ILs with carboxylic acids will reduce the basicity and viscosity of ILs and thus makes them suitable for many more applications in industrial processes. The thermophysical properties, namely, density and speed of sound, were measured for IL, [EPMpyr](+)[SAL](-), and its two binary mixtures with acetic and propionic acids. These thermophysical properties were measured at different temperatures at 5 K intervals, ranging from T = 293.15-313.15 K. From these experimental values, thermodynamic parameters such as isentropic compressibility (k(s)), deviation in isentropic compressibility (Delta k(s)), and excess molar volume (V-m(E)) were computed. It was found that V-m(E) and Delta k(s) decreased with increasing temperatures and gave negative values for the entire composition of both binary systems. These derived thermodynamic parameters (V-m(E) and Delta k(s)) have been correlated using the Redlich-Kister model to obtain binary coefficients and standard errors.
