Dyslipidemia is one of the most important risk factors for coronary artery disease (CAD), and low-density lipoprotein cholesterol (LDL-C) is used to measure dyslipidemia. Non-high-density lipoprotein cholesterol (non-HDL-C) seems to be an alternative parameter to LDL-C as it is not influenced by triglyceride (TG) levels. The aim of this study is to compare non-HDL-C and LDL-C levels as risk markers in CAD patients. Materials and methods: One hundred and ten CAD patients and 42 individuals with normal coronary angiography results were included in this study. Patients were divided into 2 groups: TG < 200 mg/dL (n = 75) as group 1 and TG > 200 mg/dL (n = 35) as group 2. …

Role Of Autophagy In The Pathogenesis Of Alzheimer Disease, Muhammet Cemal Kizilarslanoğlu, Zekeri̇ya Ülger
Turkish Journal of Medical Sciences
Alzheimer disease (AD) is the most common progressive neurodegenerative disorder causing increased morbidity and mortality. It is characterized by accumulation of amyloid-β in neurons. As there is no known definitive treatment of this disorder, studies trying to determine its exact pathogenetic pathways and target therapies for these specific pathways are being rapidly conducted. Autophagy is one of the areas of interest in studies on the pathogenesis of AD. It is a process of self-digestion that is thought to be a response to stressors and allows cells to adapt to environmental changes. There is accumulating evidence showing an association between autophagy …

Turkish Journal of Medical Sciences
Alzheimer disease (AD) is one of the most common neurodegenerative diseases and the most prevalent form of dementia. Some factors in the development of AD, age being the best-known one, have been suggested; however, no causes have been found yet. The pathophysiology of the disease is highly complex, current therapies are palliative, and a cure is still lacking. Adverse effects of anesthetics in the elderly have been reported since the 1950s; however, awareness of this old problem has recently gained importance again. Whether exposure to surgery and general anesthesia (GA) is associated with the development of AD has been questioned. …

Background/aim: To compare plasma vitamin D concentrations among patients with normal cognitive function (control group), mild cognitive impairment (MCI), and Alzheimer disease (AD). Materials and methods: In total, 158 patients with AD, 228 patients with MCI, and 603 control subjects were included. Plasma levels of 25-hydroxyvitamin D were measured after comprehensive geriatric assessment and compared among groups. SPSS 15.0 was used for statistical analysis. Results: Mean levels of 25-hydroxyvitamin D were significantly different among the 3 groups of AD patients, MCI patients, and controls (P < 0.001). Post hoc analysis revealed that the levels were significantly lower in the MCI group than the control group (P = 0.002) and significantly lower in the AD group than the control group (P = 0.003). Multivariate analysis showed that age (OR: 1.070, 95% CI: 1.025-1.116, P = 0.002), instrumental activities of daily living score (OR: 0.920, 95% CI: 0.850-0.995, P = 0.037), 25-hydroxyvitamin D level (OR: 0.959, 95% CI: 0.932-0.987, P = 0.004), and diabetes mellitus (OR: 2.476, 95% CI: 1.153-5.319, P = 0.020) were factors independently associated with AD. Conclusion: This study demonstrated that there is a correlation between plasma 25-hydroxyvitamin D levels and cognitive functions.

Turkish Journal of Medical Sciences
Background/aim: Alzheimer disease (AD) is triggered by interactions of multiple genetic and environmental factors. The APOE gene E4 allele is the best-known risk factor for AD, yet it represents a small ratio of genetic factors. According to genome-wide association studies, the BIN1 gene is the second important risk factor for AD, following the APOE gene. We aimed to identify a novel biomarker indicating susceptibility to AD by investigating APOE alleles and BIN1 gene polymorphisms in a Turkish population. Materials and methods: Fifty-three AD patients and 56 controls were included to examine polymorphism and allele frequency of the APOE and BIN1 …

Background/aim: Data about contact allergen sensitization (CAS) in children with atopic dermatitis (AD) are limited. The purpose of this study was to identify the frequency and patterns of CAS in children with AD by using a ready-to-use patch test system. Materials and methods: After receiving the history of CAS in the patients, the severity of AD and IgE-mediated allergen sensitization were determined. Results: Of 134 children with AD, 33.8% (n = 45) had at least 1 positive reaction. The most frequent positive reaction was to nickel sulfate (NS) (37.8%, 17/45), followed by methylchloroisothiazolinone (20.0%, 9/45) and thimerosal (15.6%, 7/45). The …

Background/aim: Urticaria is a vascular skin reaction characterized with papules and plaques. Neopterin is accepted as an immunologic marker and an indicator of activation of the immune system. Homocysteine and asymmetric dimethylarginine (ADMA) are the markers of increased vascular resistance. Alteration in vascular resistance has a role in the pathogenesis of urticaria. We aimed to investigate whether there is a relationship between urticaria and neopterin, homocysteine, or ADMA. Materials and methods: The study is designed as a prospective descriptive study and patients with a diagnosis of urticaria in the emergency department were included in the study. Demographic data and characteristics …

Background/aim: Heat shock proteins (HSPs) are expressed in human spermatozoa and play a role in sperm function. MicroRNAs (miRNAs) regulate gene expression, and the possible involvement of miRNAs in the regulation of HSP gene expression in sperm was investigated in this study. Materials and methods: miRNAs differentially expressed in 8 copies of an oligoasthenozoospermic semen group (OA) were identified by comparison with a normal male semen control group (NC) using microarray technology. Potential targets of HSP proteins among the differentially expressed miRNAs were further investigated. Results: HSP40, HSP60, HSP70, and HSP90 were all found to be expressed in human ejaculated …
