Turkish Journal of Medical Sciences
Background/aim: VKORC1 and CYP2C9 genetic polymorphisms may not accurately predict warfarin dose requirements. We evaluated an existing warfarin dosing algorithm developed for Malaysian patients that was based only on VKORC1 and CYP2C9 genes. Materials and methods: Five Malay patients receiving warfarin maintenance therapy were investigated for their CYP2C9*2, CYP2C9*3, and VKORC1-1639G>A genotypes and their vitamin K-dependent (VKD) clotting factor activities. The records of their daily warfarin doses and international normalized ratio (INR) 2 years prior to and after the measurement of VKD clotting factors activities were acquired. The mean warfarin doses were compared with predicted warfarin doses calculated from …

Why Is Alzheimer's Disease Confused With Other Dementias?, Dursun Aygün, İbrahi̇m Levent Güngör
Why Is Alzheimer's Disease Confused With Other Dementias?, Dursun Aygün, İbrahi̇m Levent Güngör
Turkish Journal of Medical Sciences
Alzheimer disease (AD) is the most common cause of dementia. The cardinal manifestation of AD is progressive loss of memory. However, there are some nonamnestic presentations of AD, also called atypical AD. Symptoms of AD can sometimes start suddenly. In the presence of atypical symptoms or sudden onset, it may be difficult to distinguish AD from other dementias. We would like to discuss the confusing features of atypical AD that mimic other dementias. In this review, the literature associated with confusing features of AD, suggesting other dementia syndromes, is reviewed. In addition, a case of semantic dementia (SD) with the …
Postoperative Cognitive Dysfunction And Alzheimer Disease, Berri̇n Işik
Postoperative Cognitive Dysfunction And Alzheimer Disease, Berri̇n Işik
Turkish Journal of Medical Sciences
Alzheimer disease (AD) is the most prevalent neurodegenerative disorder in elderly people. Patients with AD appear to be particularly at risk for cognitive deterioration following anesthesia. Some in vitro studies suggest that exposure to general anesthesia (GA) promotes the AD process. On the other hand, there are no clinical studies that clearly demonstrate that GA is a cause of cognitive dysfunction in patients with probable AD. The aim of this research was to discuss the relation between postoperative cognitive dysfunction (POCD) and AD according to the literature. In vivo studies examining AD biomarkers postoperatively and in vitro studies exploring amyloid-β …

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 …

Turkish Journal of Medical Sciences
Background/aim: A number of genetic variants from different genes have been reported to be related to late-onset Alzheimer disease (LOAD) susceptibility. From these genes, polymorphisms in CLU and TLR2 have been replicated in several studies. In this study we examined the association of rs11136000 in CLU and the TLR2 -196 to -174 del polymorphism with the risk of LOAD in a northwestern Iranian population. Materials and methods: We conducted a case-control study with a dataset of 160 LOAD patients and 163 healthy controls. To examine polymorphisms of CLU and TLR2 in LOAD we used the PCR/RFLP method and genotype frequencies …

Turkish Journal of Medical Sciences
Background/aim: Nerve growth factor (NGF) promotes the survival and differentiation of sensory and sympathetic neurons. Several studies have found that certain neuropathological factors stimulate NGF receptor expression and release the truncated nerve growth factor receptor (TNGFR) to biological fluids. The aim of this pilot study was to determine urine TNGFR levels in patients with dementia and to verify whether TNGFR can be used as a biomarker of dementia. Materials and methods: Twelve patients with dementia and 12 healthy individuals were asked to voluntarily participate in this study. Ages, sexes, and weights were matched. The first morning urine samples were collected …

Turkish Journal of Medical Sciences
Acetaminophen (APAP) overdose results in severe liver damage that may develop into acute liver failure. Recent studies have demonstrated that inhibition of poly(ADP-ribose) polymerase (PARP) decreases tissue necrosis and inflammation. We evaluated the efficacy of 3-aminobenzamide (3-AB), a PARP inhibitor, in a rodent model of APAP-induced hepatotoxicity. Materials and methods: Twenty-four Sprague-Dawley rats were divided equally into 3 experimental groups: sham group, APAP group, and APAP + 3-AB group. In the experimental treatment groups APAP was administered orally at 1 g/kg and, in the APAP + 3-AB group, 3-AB was administered intraperitoneally at a dose of 20 mg/kg exactly 1 …

Turkish Journal of Medical Sciences
To investigate polymorphism characteristics of HIV-1 gp120 and its 5 hypervariable regions. Materials and methods: Length polymorphism, potential number of N-linked glycosylation sites (PNGSs), and sequence characteristics of nearly all available global gp120 and its 5 hypervariable regions from HIV-1 subtypes A, B, C, D, G, and H were analyzed. Results: We found that the majority of HIV-1 gp120s have 496-515 amino acids and 21-30 PNGSs, suggesting that a gp120 with this length might be a good virus candidate for vaccine development. Among 5 hypervariable regions, the V3 regions had the lowest levels of length polymorphism and heterogeneity and less …

In this study, the in vitro and in vivo effectiveness of caffeic acid (3,4-dihydroxycinnamic acid) phenethyl ester (CAPE) in combination with bortezomib, a proteasome inhibitor, was explored in multiple myeloma (MM) cells. Materials and methods: The cytotoxic effects of CAPE and bortezomib were determined by XTT cell proliferation assay. Apoptosis levels were analyzed with annexin V-fluorescein isothiocyanate, nuclear factor kappa beta (NF-\kappaB) was analyzed with electrophoretic mobility-shift assay, and interleukin (IL)-6 levels were analyzed with enzyme-linked immunosorbent assay to evaluate CAPE's mechanism of action. To investigate the in vivo effectiveness of CAPE and bortezomib, an experimental plasmacytoma model was induced …

\beta-Lactamase production is considered one of the most important resistance mechanisms among virulent Pseudomonas aeruginosa isolates. The aim of this study was to compare the production and antimicrobial resistance patterns of some virulence factors in extended spectrum \beta-lactamase (ES\betaL)-producing and nonproducing P. aeruginosa clinical isolates. Materials and methods: Out of 183 different clinical specimens, 104 Pseudomonas aeruginosa isolates were recovered. The isolates were screened for ESbL production using the double disk diffusion test and phenotypic confirmatory disk diffusion test. All isolates were tested for susceptibility to 25 antimicrobials, as well as for expression of various virulence factors including pigment, hemolysin, …

The West Nile virus (WNV) is a mosquito-borne flavivirus causing different forms of infection among humans, varying from asymptomatic illness to fetal central nervous system infection. Turkey lies within an endemic region for WNV. Transfusion of infected blood products is another well-documented major route of transmission. The aim of our study was to investigate the presence of WNV viremia among a healthy donor population from the western part of the country. Materials and methods: A total of 438 healthy volunteer blood donors were included in the study. The presence of WNV RNA was investigated by quantitative real-time reverse-transcriptase polymerase chain …
