The role of carcinoembryonic antigen (CEA) in Parkinson's disease (PD) has not been previously investigated. The aim of the present study was to evaluate the serum level of carcinoembryonic antigen, high-sensitivity C-reactive protein (hs-CRP), and Neutrophil/lymphocyte ratio (NLR) among patients with Parkinson's disease and to examine the relationship between these inflammatory markers. The cross-sectional design includes 51 patients with Parkinson's disease and 50 age- and sex-matched healthy controls. We investigated the differences in hs-CRP, CEA, and NLR levels between these two groups. CEA was significantly higher in PD patients relative to the control group (mean 2.40 ± 1.51 vs. 1.72 ± 0.87 (ng/mL), respectively; p = 0.015). Mean NLR was significantly higher in PD patients relative to the control group (mean 3.1 ± 1.3 vs. 2.1 ± 0.32, respectively; p < 0.001). Serum level of hs-CRP was higher in PD patients than in control group (mean 1.04 ± 0.62 and 0.54 ± 0.31, respectively; p < 0.01). Correlation analysis revealed significant correlation between hs-CRP, CEA, and Neutrophil/lymphocyte ratio (p < 0.05). This study demonstrates for the first time the association between CEA, hs-CRP, NLR, and PD. We found CEA, hs-CRP, and NLR levels to be significantly higher in the PD patients than in the normal controls.

Our study has shown that Turkish stroke survivors have sexual health needs during the rehabilitation process, though this has not been addressed previously. Sexual health needs seem to be affected by cultural factors and biases.

We found serum albumin levels were significantly lower and the NLR was significantly higher in the acute period of CSE. Neutrophil-mediated inflammation may be important in the aetiopathogenesis of CSE.

To date, there have not been enough studies about the effects of curcumin against oxidative stress on sciatic nerves caused by streptozotocin (STZ) in diabetic rats. Therefore, this study was undertaken to determine whether curcumin, by virtue of its antioxidant properties, could affect the oxidant/antioxidant balance in the sciatic nerve and brain tissues of streptozotocin (STZ)-induced diabetic rats. A total of 28 rats were randomly divided into four groups of seven rats each: normal controls, only curcumin treated, diabetic controls, and diabetics treated with curcumin. Biomarkers-malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and NO levels-for oxidative stress in the brain and sciatic nerve tissues of the rats were measured. We found a significant increase in MDA, NO, TOS, and OSI, along with a reduction in TAS levels in the brains and sciatic nerves of the STZ-induced diabetic rats (for both parameters p < 0.05). The MDA, TOS, OSI, and NO levels in these tissues were significantly reduced in the curcumin-treated diabetic group compared to the untreated diabetic group. In conclusion, the results of this study suggested that curcumin exhibits neuroprotective effects against oxidative damage in the brain and sciatic tissues of diabetic rats.

There are limited studies evaluating the fibrinogen levels in patients with migraine. It remains unknown whether the levels of the haematological marker of thromboembolism, D-dimer, and the levels of galectin-3, which plays an important role in inflammation as a proinflammatory mediator, change during the attacks in patients with migraine. The present study aims to compare galectin-3, fibrinogen and D-dimer levels in patients with migraine during the attacks and interictal periods, and to compare galectin-3, fibrinogen and D-dimer levels between patients with migraine and healthy controls to investigate the role of these parameters in the pathogenesis of migraine. Fifty-nine patients with migraine and 30 age-gender matched healthy control subjects were enrolled in the study. Blood galectin-3, fibrinogen and D-dimer levels were measured in patients with migraine. Patients with migraine had higher levels of galectin-3, fibrinogen and D-dimer compared to the healthy controls (p < 0.05). No statistically significant difference was found between galectin-3 and fibrinogen levels during the attacks and interictal period in the migraine group (p > 0.05). Migraine patients had higher D-dimer levels during the attacks compared to the patients in the interictal period in the migraine group (p = 0.05). In conclusion, we found increased levels of fibrinogen, D-dimer and galectin-3 in patients with migraine compared to the healthy control group. Furthermore, we showed increased galectin-3 levels in patients with migraine, and higher D-dimer levels during migraine attacks compared to the interictal periods for the first time. These findings may be associated with the hypercoagulability and neurogenic inflammation during migraine headaches.

Glutamate excitotoxicity and oxidative stress are held responsible for the pathogenesis of Alzheimer's disease (AD). Prolidase is known to have a crucial part in the recycling of proline for collagen synthesis. Elevated proline levels have been shown to increase glutamate concentration. To our knowledge, prolidase activity in AD has not yet been studied. In this study, we aimed to reveal the relationship of AD with oxidative stress and collagen turnover by comparing AD patients and healthy control group with regard to total antioxidant status (TAS), total oxidant status (TOS), and prolidase levels. Fifty patients (mean age, 72.5 ± 8.9 years) diagnosed with AD and a control group comprised of 39 healthy individuals (mean age, 69.1 ± 7.1 years) were compared relative to serum TAS, TOS, and prolidase levels. The relationship of cognitive performance with prolidase, TAS, and TOS was evaluated by Mini mental state examination (MMSE). Alzheimer's disease group demonstrated statistically significantly higher prolidase and TOS levels as compared to the control group (p = 0.01, p = 0.018, respectively). Total antioxidant status level was significantly lower in the dementia group than in the control group (p = 0.032). MMSE manifested a negative correlation with prolidase and TOS levels (p = 0.001, r = -0.33; p = 0.002, r = -0.32, respectively), while displaying a positive correlation with TAS levels (p = 0.002, r = 0.32). In conclusion, elevated prolidase and TOS levels along with reduced TAS concentrations suggest that oxidative stress and collagen breakdown are involved in the cognitive impairment in AD.
