Alzheimer's disease (AD) is the most common cause of dementia in elderly people. Because of the lack of effective treatments for this illness, research focused on identifying compounds that restore cognition and functional impairments in patients with AD is a very active field. Since its discovery in 1993, the serotonin 5-HT6 receptor has received increasing attention, and a growing number of studies supported 5-HT6 receptor antagonism as a target for improving cognitive dysfunction in AD. This article reviews the rationale behind investigations into the targeting of 5-HT6 receptors as a symptomatic treatment for cognitive and/or behavioral symptoms of AD...

BACKGROUND: To this day the definite diagnosis of Alzheimer's disease still relies on post-mortem histopathological detection of neurofibrillary tangles and beta-amyloid deposits. Amyloid positron emission tomography (PET) is a new diagnostic tool that enables the in vivo quantification of pathological beta-amyloid deposits. The aim of the current study was to evaluate to what extent (18)F-florbetaben-PET (FBB-PET) influences the diagnosis of patients with dementia. MATERIAL AND METHODS: Imaging with FBB-PET was performed on 33 patients from our outpatient department for cognitive neurology...

The transcription factor STAT1 displays antitumor functions for certain forms of cancer via immunoregulatory and cell-autonomous pathways. Paradoxically, STAT1 can promote the survival of different tumor types treated with chemotherapeutic drugs through mechanisms that are not clearly defined. Herein, we demonstrate that STAT1 displays prosurvival effects in human KRAS colon tumor cells by regulating pathways that converge on the initiation of mRNA translation. Specifically, STAT1 increases PI3K class IB signaling and promotes the downregulation of the programmed cell death protein 4 (PDCD4), a protein with tumor-suppressive properties...

Thrombosis and bleeding are among the most common causes of morbidity and mortality in patients with renal disease or liver disease. The pathophysiology underlying the increased risk for venous thromboembolism and bleeding in these 2 populations is distinct, as are considerations for anticoagulation. Anticoagulation in patients with kidney or liver disease increases the risk of bleeding; this risk is correlated with the degree of impairment of anticoagulant elimination by the kidneys and/or liver. Despite being in the same pharmacologic category, anticoagulant agents may have varied degrees of renal and liver metabolism...

PURPOSE: This study explored the performance of trigger in detecting adverse drug reactions (ADRs), the confounding variables impairing the causal association of the ADRs, and the underreporting rate by hospital health professionals. METHODS: A 6-month cross-sectional study was conducted in a public general hospital. Data collection was conducted in 2 stages: (1) screening of patient hospitalizations to identify suspected ADRs with 9 triggers developed by the Institute of Healthcare Improvement; and (2) chart review to perform the causality assessment of the suspected ADRs identified, to describe the confounding variables associated with detection of suspected ADRs that were not drug induced, and to analyze the positive predictive value of triggers in recognizing ADRs...

Y-box binding protein-1 (YB-1) is a pleiotropic molecule that binds DNA to regulate genes on a transcriptional level in the nucleus and binds RNA to modulate gene translation in the cytoplasm. In our previous studies, YB-1 was also characterized as a fetal hepatic protein that regulates the maturation of hepatocytes and is upregulated during liver regeneration. Moreover, YB-1 has been shown to be expressed in human hepatocellular carcinoma (HCC). However, the role of YB-1 in HCC remains unclear. Here, we aimed to characterize the role of YB-1 in HCC...

The efficacy of treatment for intravenous elemental mercury intoxication has not been fully studied with regard to clinical outcomes, and treatment recommendations vary. We treated a 41-year-old man with a history of drug abuse and depression who attempted suicide using 1 mL (13.53 g) metallic Hg i.v. He was admitted to the hospital two months later for dyspnoea and thoracic pain and was diagnosed with pneumonia. Hg deposits were seen in the lungs and extra-pulmonary organs. His blood level (372 μg/L) exceeded the population level of 5 μg/L by more than 70-fold...

BACKGROUND: Donepezil is an acetylcholinesterase inhibitor frequently prescribed for the treatment of mild cognitive impairment (MCI) though not approved by the Food and Drug Administration for this indication. In Alzheimer's disease, butyrylcholinesterase (BChE) activity increases with disease progression and may replace acetylcholinesterase function. The most frequent polymorphism of BChE is the K-variant, which is associated with lower acetylcholine-hydrolyzing activity. BChE-K polymorphism has been studied in Alzheimer's disease progression and donepezil therapy, and has led to contradictory results...

This study investigated the effect of α-amyrin (a pentacyclic triterpene) on high-fructose diet (HFD)-induced metabolic syndrome in rats. Male Wistar rats were randomly distributed into different groups. The control group was fed normal rat chow diet. The HFD group was fed HFD (60%; w/w) for 42 days. Pioglitazone (10 mg/kg, orally, once daily) was used as a standard drug. α-Amyrin was administered in 3 doses (50, 100, and 200 mg/kg, orally, once daily along with HFD). Plasma glucose, total cholesterol, triglycerides, and high-density lipoprotein cholesterol (HDL-C) were estimated...

Coronary heart disease is still the leading cause of death in industrialized nations. Even though revascularization strategies such as coronary artery bypass graft surgery, percutaneous coronary intervention and enhanced drug therapy significantly improved the outcome, about 30 % of patients develop chronic heart failure. Ischemic heart disease and heart failure are characterized by an adverse remodeling of the heart, featuring cardiomyocyte hypertrophy, increased fibrosis and capillary rarefaction. Therefore, gene therapeutic approaches for the treatment of heart failure, such as the modulating contractile function or therapeutic neovascularization, seem to be promising...

BACKGROUND: Sleep alterations can impair quality of life and contribute to disease progression but they, and their features and contributing factors, are rarely analysed in institutionalised older individuals. In this study we investigated sleep alterations, the factors involved, and the role of cortisol in sleep-related problems in institutionalised individuals. METHODS: We conducted a descriptive cross-sectional study in participants living in nursing homes in Valencia (Spain); sleep alterations were determined based on two validated tools: the Athens insomnia scale and Oviedo sleep questionnaire...

BACKGROUND: Mental disorders are the most common health problems in the worldwide population. Current medicines against these conditions have undesired side effects or limited effectiveness. These disadvantageous pharmacological and therapeutic characteristics provoke a low adherence to treatment in an important percentage of patients with mental disorders. Since ancient times, ethnically different groups have been using plants extracts as medicines for the treatment of mental conditions including dementia, depression and anxiety disorders...

BACKGROUND: Erlotinib and gefitinib are weak base drugs whose absorption and clinical efficacy may be impaired by concomitant gastric acid suppressive (AS) therapy, yet proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2As) are widely indicated in non-small cell lung cancer (NSCLC) patients for the prevention and treatment of erlotinib-induced gastrointestinal injury and corticosteroid-associated gastric irritation. We assessed the clinical relevance of this potential drug-drug interaction (DDI) in a retrospective cohort of EGFR-mutant NSCLC patients...

Stag3, a meiosis-specific subunit of cohesin complex, has been demonstrated to function in both male and female reproductive systems in mammals. However, its roles during oocyte meiotic maturation have not been fully defined. In the present study, we report that Stag3 uniquely accumulates on the spindle apparatus and colocalizes with microtubule fibers during mouse oocyte meiotic maturation. Depletion of Stag3 by gene-targeting morpholino disrupts normal spindle assembly and chromosome alignment in oocytes...

Parkinson's disease (PD) is a common neurodegenerative disease. Literature sources indicate the association of PD and mutations in the glucocerebrosidase A (GBA) gene. According to our study, the frequency of the two most common mutations in the GBA gene, N370S and L444P, is 1.85%. Mutation carriers have slower progression of motor symptoms, but are more likely to develop drug-induced motor fluctuations and dyskinesia. In carriers of GBA mutations, the severity of cognitive impairment corresponds to age-matched patients without mutations...

Increased frequency of cells with chromosomal aberrations was revealed in 48-h cultures of peripheral blood lymphocytes isolated North Ossetia residents with impaired reproductive function. After 2-week treatment with antimutagenic drug Afobazole, the percentage of cells with chromosomal aberrations significantly decreased from 3.77±0.20 to 2.48±0.24% (p<0.001). Significant differences between chromosome damage levels before and after administration of the drug suggest that Afobazole could be recommended for protective purposes to this group of patients...

Qi Tang, Peipei Song, Lingzhong Xu
The World Health Organization (WHO) has emphasized that aging of the population is inextricably linked to many other global public health issues, such as universal health coverage, non-communicable diseases, and disability. However, Alzheimer's Disease International (ADI) estimates that 46.8 million elderly people worldwide were living with dementia in 2015. Alzheimer's disease (AD), the most common form of dementia, is one of the most common neurodegenerative diseases and is the main cause of cognitive impairment...
