Objective: To analyse the relationships between serum leptin, vitamin D status, muscle strength and physical performance in OA patients.
Methods: A total of 208 knee OA patients were enrolled. Serum leptin, vitamin D, muscle strength and physical performance were evaluated.
Results: OA patients with sarcopenic obesity had significantly higher serum leptin levels than those with non-sarcopenic obesity. In addition, knee OA patients with sarcopenic obesity displayed low grip strength and poor physical performance. Furthermore, high serum leptin was negatively associated with vitamin D and physical performance.
Conclusions: Serum leptin levels were correlated with low vitamin D, reduced muscle strength and functional impairment, suggesting that serum leptin might serve as a biomarker reflecting physical performance in OA patients. 相似文献
Objective: To evaluate circulatory apoptotic markers and oxidative stress in patients with PCOS.
Materials and methods: Forty-four women with PCOS, and 44 healthy women as controls were enrolled in the study. Oxidative stress parameters and caspases levels were measured in serum.
Results: The caspase 9 level was significantly lower and related with oxidant status in patients with PCOS, while the circulating levels of caspases 3 and 7 were statistically similar in both groups.
Discussion: This study is the first report demonstrating the circulating levels of apoptotic markers and their relationship with oxidant status in PCOS.
Conclusion: The circulating caspase 9 and oxidant status might contribute to apoptotic dysregulation in PCOS. 相似文献
Objective: The objective of this study is to investigate the association between sleep-disordered breathing (SDB) – a source of oxidative stress – and CML.
Materials and methods: About 1002 participants in the Cardiovascular Health Study (CHS) were studied.
Results: Women with SDB had significantly higher CML concentration compared with those without SDB (OR?=?1.63, 95%CI?=?1.03–2.58, p?=?0.04). The association was not significant among men.
Discussion: SDB was associated with CML concentration among elderly women but not men in the Cardiovascular Health Study.
Conclusion: Accumulation of CML may be an adverse health consequence of SDB 相似文献
Objective: The aim of this paper is the discovery of new non-invasive biomarker for the monitoring of VHLD patients.
Materials and methods: We compared the urinary proteome of VHLD patients, ccRCC patients and healthy volunteers.

Objective: To evaluate the relationship between sCD40l and survival, CVE and mortality in HD patients on long-term follow-up.
Methods: We registered 46?HD patients’ baseline characteristics, mortality and CVE for 108 months.
Results: SCD40l correlated positively with C-reactive protein, was higher in survivors, but had no impact on survival and was not predictive for CVE or CV mortality.
Conclusion: The levels of sCD40l have no influence on survival or CVE and mortality in HD patients in a long-term follow-up. 相似文献
Objective: To asses the association of Guanine nucleotide-binding protein (GNB3) (C825T) gene's polymorphism with T2DM.
Materials and methods: A case–control study including 400 North Indians was performed using Polymerase Chain Reaction–Restriction Fragment Length Polymorphism (PCR-RFLP) approach to analyze genetic polymorphism.
Results: No significant difference was observed in genotype and allele frequencies of GNB3 gene on comparing cases with controls.
Discussion: Our study is in agreement with studies on Polish, Japanese, Hispanic-American and Danish populations who observed no significant association between GNB3 (C825T) polymorphism and T2DM.
Conclusion: GNB3 (C825T) polymorphism is not associated with T2DM. 相似文献
Objective: The study examined the early release kinetics of TnTuORF.
Materials and methods: We analyzed the time course of the release of cardiac troponins I and T and TnTuORF in patients (n?=?31) with hypertrophic obstructive cardiomyopathy undergoing transcoronary ablation of septal hypertrophy (TASH).
Results: Fifteen minutes after TASH, the levels of both troponins increased significantly (cTnT median: 18?ng/L versus 27?ng/L; cTnI median: 15?ng/L versus 25?ng/L). TnTuORF showed no variation.
Discussion: We observed a significantly greater increase in cTnI compared with cTnT.
Conclusion: Our results demonstrate that troponin assays allow early detection of myocardial injury, whereas TnTuORF levels remain unchanged in this setting. 相似文献
Aims: To explore which factors have more importance in determining the pre-fledging daily survival rates in a Yellow-legged Gull population from northern Iberia. Specifically, we tested for the effect of hatching date and order, body size and condition and meteorological conditions on pre-fledging survival.

Objective: To examine effects of nickel exposure on plasma oxidative and anti-oxidative biomarkers.
Materials and methods: Biomarker data were collected from 154 workers with various levels of nickel exposure and from 73 controls. Correlations between nickel exposure and oxidative and anti-oxidative biomarkers were determined using linear regression models.
Results: Workers with a exposure to high nickel levels had significantly lower levels of anti-oxidants (glutathione and catalase) than those with a lower exposure to nickel; however, only glutathione showed an independent association after multivariable adjustment.
Discussion and conclusion: Exposure to high levels of nickel may reduce serum anti-oxidative capacity. 相似文献

Methods: Secondary analyses of an observational clinical pilot study, including 60 patients with septic shock, 30 postoperative controls and 30 healthy volunteers.
Results: Plasma levels of sTREM-1 were found to identify patients with septic shock more effectively than procalcitonin and C-reactive protein. Moreover, sTREM-1 was identified to be an early predictor for survival in patients with septic shock.
Conclusion: Due to its diagnostic as well as prognostic value in sepsis syndrome, implementation of sTREM-1 measurements in routine diagnostics should be taken into account. 相似文献
