Aim: To investigate the oxidative stress hypothesis in patients with Alzheimer type dementia.
Method: Serum melatonin, Zn, Cu, Fe, and malondialdehyde (MDA) concentrations and erythrocyte superoxide dismutase (SOD) activity were measured in patients with Alzheimer disease. Mini-Mental State Examination (MMSE) scores were obtained for the patients and their age- and sex-matched healthy controls.
Results: MMSE score was 16.81.3 in patients with Alzheimer disease, and 28.22.4 in control group. Melatonin levels were lower in the Alzheimer disease group (170.55.2 pg/mL) than in the control group (205.25.8 pg/mL) (p<0.001). Fe, SOD, and MDA levels were higher in Alzheimer disease group (131.74.8 microg/dL, 1,51090 U/g Hb, and 38.14.7 nmol/mL; respectively) than in the control group (97.14.1 microg/dL, 1,12050 U/g Hb, and 17.21.6 nmol/mL; respectively) (p<0.001 for all comparisons). A statistically significant negative correlation between melatonin and SOD (r=-0.421, p=0.014) and a positive correlation between age and Fe (r=0.325, p=0.049) were found only in the Alzheimer disease group. Correlation between age and melatonin was positive (r=0.481, p=0.006) in Alzheimer disease group and negative (r=-0.472, p=0.009) in the control group.
Conclusion: Melatonin blood concentration was significantly decreased, and Fe and MDA levels were increased in the patients with Alzheimer disease. We believe that low level of melatonin, especially if there is a simultaneous increase in Fe level, is associated with the development of Alzheimer disease.

Background: Considering how gendered experiences play a role in the lives of patients with heart failure (HF) is critical in order to understand their experiences, optimise clinical care and reduce health inequalities.
Objectives: The aim of our study was to review how gender is being studied in qualitative research in HF, specifically to (1) analyse how gender is conceptualised and applied in qualitative HF research; and (2) identify methodological opportunities to better understand the gendered experiences of patients with HF.
Eligibility Criteria: We conducted a systematic search of literature, including qualitive or mixed-methods articles focussing on patients' perspectives in HF and using gender as a primary analytical factor, excluding articles published before 2000.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-β plaques and tau tangles, leading to cognitive decline and dementia. Insulin-like Growth Factor-1 (IGF-1) is similar in structure to insulin and is crucial for cell growth, differentiation, and regulating oxidative stress, synaptic plasticity, and mitochondrial function. IGF-1 exerts its physiological effects by binding to the IGF-1 receptor (IGF-1R) and activating PI3K/Akt pathway.

The single-luminophore-based ratiometric electrochemiluminescence (ECL) sensor coupling bidirectional regulator has become a research hotspot in the detection field because of its simplicity and accuracy. However, the limited bidirectional regulator hinders its further development. In this study, by leveraging the robust predictive capabilities of machine learning, we prepared an Fe-based metal-organic framework (FeMOF) as a bidirectional regulator for modulating the dual-emission ECL signals of a single luminophore for the first time.

Background: Charcot-Marie-Tooth disease (CMT), a slowly advancing hereditary nerve disorder, presents a significant challenge in the medical field. Effective drugs for treatment are lacking, and we struggle to find sensitive markers to track the disease's severity and progression. In this study, our objective was to investigate the levels of neurofilament light chain (NfL), glial fibrillary acid protein (GFAP), fibroblast growth factor 21 (FGF-21) and growth differentiation factor 15 (GDF-15) in individuals with CMT and to compare them to a control group.

Background: Alzheimer's disease (AD) is a common neurodegenerative disorder worldwide and the using of magnetic resonance imaging (MRI) in the management of AD is increasing. The present study aims to summarize MRI in AD researches via bibliometric analysis and predict future research hotspots.
Methods: We searched for records related to MRI studies in AD patients from 2004 to 2023 in the Web of Science Core Collection (WoSCC) database.
