Pulsed nuclear magnetic resonance (NMR) is widely used in high-precision magnetic field measurements. The absolute value of the magnetic field is determined from the precession frequency of nuclear magnetic moments. The Hilbert transform is one of the methods that have been used to extract the phase function from the observed free induction decay (FID) signal and then its frequency. In this paper, a detailed implementation of a Hilbert-transform based FID frequency extraction method is described, and it is briefly compared with other commonly used frequency extraction methods. How artifacts and noise level in the FID signal affect the extracted phase function are derived analytically. A method of mitigating the artifacts in the extracted phase function of an FID is discussed. Correlations between noises of the phase function samples are studied for different noise spectra. We discovered that the error covariance matrix for the extracted phase function is nearly singular and improper for constructing the χ2 used in the fitting routine. A down-sampling method for fixing the singular covariance matrix has been developed, so that the minimum χ2-fit yields properly the statistical uncertainty of the extracted frequency. Other practical methods of obtaining the statistical uncertainty are also discussed.Macrophages have a variety of functions, such as secreting cytokines, phagocytosis, et al. Tripartite motif containing 59 (TRIM59) protein is highly expressed in tumor cells. It can regulate proliferation of tumor cells and promote tumor progression. Recent studies shown that the expression of TRIM59 was different in macrophages when stimulated by different stimuli, however, the effects of TRIM59 on macrophage gene expression profiles and functions are still unknown. In our study, we constructed RAW264.7 macrophages with high and low expression of TRIM59, and used next generation sequencing to explore the effects of TRIM59 on macrophage gene expression profiles. https://www.selleckchem.com/products/gs-9973.html Results showed that TRIM59 affected an abundant number of genes, and may affect phagocytosis and cell cycles. We also examined the expression of surface molecules, secretion of cytokines, phagocytosis, proliferation, and apoptosis of macrophages, and confirmed that TRIM59 increased the expression of FcγRs CD16/32, CD64 and the secretion of TNF-α and IL-10, promoted phagocytosis and proliferation of RAW264.7 cells, inhibited the expression of complement receptor CD11b and antigen presentation related receptors (MHCII, CD80), but TRIM59 had no significant effect on apoptosis. Our study explored the effect of TRIM59 on the gene expression and function of macrophages comprehensively.
Patients with multiple sclerosis (MS) had a 1.5-fold increase in cardiovascular diseases (CVD) mortality, compared with those without MS. Therefore, the aim of this study was to assess the CVD risk in MS patients by multiple cardiometabolic indexes and to investigate associated factors.

The MS group included 57 patients matched for age and sex to 57 healthy controls. They were evaluated for physical activity, smoking, anthropometric indices, blood pressure, and plasma biomarkers. Framingham risk score (FRS) and multiple cardiovascular risk indexes were calculated. Clinical course of disease, age at onset, disease duration, disease-modifying therapy, relapse rate, EDSS, physical and functional impairment were investigated.

The mean age was 34.6 years old. The majority (89.5%) in the MS group had a RRMS clinical course and a mild level of disability (EDSS=1.0). WC (p=0.022) and FM% (p=0.007) were different between the MS and control groups. The FRS was higher in the MS group (10% versus 0%) and this was related with high prevalence of dyslipidemia (43.8% versus 36.8%). The atherogenic index of plasma (AIP) (0.013) and Castelli risk indexes I (CRI-I) (p=0.017) and II (CRI-II) (p=0.008) and non-HDL-C (p=0.044) were higher in the MS group.

MS patients, with controlled disease course, have a higher cardiovascular risk than comparable healthy individuals. We emphasize that the use of FRS, and the monitoring of CRI-I and II, as well as AIP, are important lipid markers to manage CVD risk in individuals with MS.

About 85% of patients experience a disease subtype characterised by relapses and remittance (RRMS). While many studies have investigated factors influencing patients'' health-related quality of life (HRQoL) in RRMS, none have taken patients' fear of relapses into account. In this study, we measured the patients' self-reported HRQoL, fear of relapse (FoR), health anxiety (HA), number of relapses, duration of disease, type of medication and perceived level of side effects. Treating neurologists provided an estimate of patients' disease severity. All covariates and demographic (personal and disease-related) characteristics were included in regression modelling of their association with HRQoL. The model showed that HRQoL was most strongly associated with disease severity estimated by neurologists, which was highly correlated with the number of relapses and disease duration. However, upon adjustment for FoR (in the presence of all covariates), this association between disease severity and HRQoL attenuated, and FoR remained the only covariate significantly associated with HRQoL. Notably, our modelling also revealed a significant association between HA and FoR in RRMS patients. This study's findings have important implications for the management of MS in RRMS patients and point to the critical roles of FoR and HA as drivers of HRQoL in RRMS. Given the importance of HRQoL to the patient experience and economically, we argue that a more nuanced understanding is needed of the subjective nature of quality of life and its determinants. Interventions aimed at reducing psychological distress and anxiety should be explored.
