Alzhaimer disease

Despite extensive research, no disease-modifying therapeutic option, able to prevent, cure or halt the progression of Alzheimer's disease [AD], is currently available. AD, a devastating neurodegenerative pathology leading to dementia and death, is characterized by two pathological hallmarks, the extracellular deposits of amyloid beta (Aβ) and the intraneuronal deposits of neurofibrillary tangles (NFTs) consisting of altered hyperphosphorylated tau protein. Both have been widely studied and pharmacologically targeted for many years, without significant therapeutic results...

Alzheimer's (AD) and Parkinson's Diseases (PD) are common neurodegenerative disorders growing in incidence and prevalence and for which there are no disease-modifying treatments. While there are considerable complexities in the presentations of these diseases, the histological pictures of these pathologies, as well as several rare genetic predispositions for each, point to the involvement of maladaptive protein processing and inflammation. Importantly, the common presentations of AD and PD are connected to aging and to dysmetabolism, including common co-diagnosis of metabolic syndrome or diabetes...

The protein Klotho can significantly delay aging, so it has attracted widespread attention. Abnormal downregulation of Klotho has been detected in several aging-related diseases, such as Alzheimer's disease, kidney injury, cancer, chronic obstructive pulmonary disease (COPD), vascular disease, muscular dystrophy and diabetes. Conversely, many exogenous and endogenous factors, several drugs, lifestyle changes and genetic manipulations were reported to exert therapeutic effects through increasing Klotho expression...

Background: Previous studies have suggested that Alzheimer's disease (AD) and semantic dementia (SD) are both associated with emotional processing impairment. However, the degree and type of emotional symptoms between the two types of dementia have not been previously compared. Method: We used the Apathy Evaluation Scale (AES), the Toronto Empathy Questionnaire (TEQ), the Geriatric Depression Scale (GDS) and the Self-rating Anxiety Scale (SAS) to examine apathy, empathy, depression and anxiety, respectively...

BACKGROUND: Alzheimer's disease (AD) is a degenerative condition characterized by progressive cognitive impairment and dementia. Findings have revolutionized current knowledge of miRNA in the neurological conditions. Two regulatory mechanisms determine the level of mature miRNA expression; one is miRNA precursor processing, and the other is gene expression regulation by transcription factors. This study is allocated to the in-silico investigation of miRNA's SNPs and their effect on other cell mechanisms...

OBJECTIVE: To detect the expression of signal transducer and activator of transcription 3 (STAT3) and P-STAT3 in the brain of the APPswe/PS δE9 double transgenic mouse model of Alzhaimer's disease (AD) and investigate their possible role in AD. METHODS: APPswe/PS δE9 double transgenic mice and control mice were examined for cerebral STAT3 and P-STAT3 expressions using immunothistochemistry. RESULTS: STAT3 and P-STAT3 were expressed in the different regions of mouse brain...

OBJECTIVE: To detect the expression of miRNA-135a-5p, miRNA-135a-2-3p, miRNA-298-5p, miRNA-466b-3p and miR-669f-3p in the brain tissue of the APPswe/PS δE9 double transgenic mouse model of Alzheimer's disease using real-time PCR. METHODS: Six-month-old APPswe/PS δE9 double transgenic mice and wild-type C57 mice of the same species were examined for the expressions of miRNA-135a-5p, miRNA-135a-2-3p, miRNA-298-5p, miRNA-466b-3p and miR-669f-3p in the brain tissue using real-time PCR...

Aluminum is used in a large number of anthropogenic processes, leading to aquatic ecosystems pollution. Diverse studies show that in mammals this metal may produce oxidative stress, is neurotoxic, and is involved in the development of neurodegenerative disorders, such as Alzhaimer's and Parkinson's diseases. Nevertheless, there are only few studies with respect to Al-induced neurotoxicity on aquatic fauna, particularly on fishes of economical interest, such as the grass carp (Ctenopharingodon idella). This study evaluates Al-induced toxicity on the grass carp C...

PURPOSE: Evaluation of the level of the family readiness to look after a person suffering from the Alzheimer's disease. MATERIAL AND METHODS: In the research an authorized questionnaire was used, which comprised knowledge concerning the disease, coping with the situation, looking after a patient and an open test. RESULTS: It was shown that the level of knowledge about Alzheimer's disease corresponds to the level of education (p < 0.05)...
