BACKGROUND Renal-Hepatic-Pancreatic dysplasia syndrome described by Ivemark in 1959 constitutes a triad pancreatic fibrosis, renal dysplasia and hepatic dysgenesis. CASE PRESENTATION We describe two unrelated cases of Renal-Hepatic-Pancreatic dysplasia syndrome in stillborn babies. The characteristic microscopic features were present in both the cases. The second case illustrates the unique a...
Neuropsychiatric symptoms in Alzheimer's disease (AD) are prevalent, however their relationship with patterns of cortical atrophy is not fully known. Objectives To compare cortical atrophy's patterns between AD patients and healthy controls; to verify correlations between neuropsychiatric syndromes and cortical atrophy. Method 33 AD patients were examined by Neuropsychiatric Inventory (NPI). Pa...
Monoclonal antibody 3F12 identifies a cytoplasmic antigen of 49 kDa in human hippocampus and neocortex. The distribution of 3F12 immunoreactive neurons closely matches that of Alzheimer's disease (AD) targeted neurons in these areas. In some hippocampal neurons of AD patients, this antigen colocalizes with ALZ-50, indicating the presence of AD pathology in these neurons. Molecular characterizat...
Beta-amyloid (Aβ) oligomers contribute to the pathophysiology of Alzheimer disease (AD), and metabotropic glutamate receptor 5 (mGluR5) has been shown to act as a receptor for both Aβ oligomers and cellular prion proteins. Furthermore, the genetic deletion of mGluR5 in an APPswe/PS1ΔE9 mouse model of AD improves cognitive function and reduces Aβ plaques and Aβ oligomer concentrations. Here, we ...
Individuals with Down Syndrome (DS), or trisomy 21, develop Alzheimer's disease (AD) pathology by approximately 40 years of age. Chromosome 21 harbors several genes implicated in AD, including the amyloid precursor protein and one homologue of the β-site APP cleaving enzyme, BACE2. Processing of the amyloid precursor protein by β-secretase (BACE) is the rate-limiting step in the production of t...
Clinical and neuropathologic evidence points to the development of Alzheimer's disease (AD) in seven Down's syndrome patients above age 40. Dementia was observed in these patients over periods of 2.5 to 9.2 years. The first clinical sign of AD, visual memory loss, was succeeded by impaired learning capacity and decreased occupational and social functioning, and culminated in seizures and urinar...
Spatial navigation is a skill of determining and maintaining a trajectory from one place to another. Mild progressive decline of spatial navigation develops gradually during the course of physiological ageing. Nevertheless, severe spatial navigation deficit can be the first sign of incipient Alzheimer's disease (AD), occurring in the stage of mild cognitive impairment (MCI), preceding the devel...
Background Autosomal dominant hyper-IgE (AD-HIES), also called Job’s syndrome, is a rare primary immunodeficiency caused by dominant mutations in STAT3. AD-HIES is characterized by elevated levels of IgE, an ineffective immune response to several infectious agents, and connective tissue and arterial abnormalities. To date, coronary artery evaluation in AD-HIES patients has been limited to lumen...
Alzheimer’s Disease (AD) is a multifactorial neurological syndrome with the combination of aging, genetic, and environmental factors triggering the pathological decline. Interestingly, the importance of the Acetylcholinesterase (AChE) enzyme has increased due to its involvement in the β-amyloid peptide fibril formation during AD pathogenesis. In silico technique, QSAR has proven its usefulness ...
Background Alzheimer's disease (AD) is hypothesised as a disconnection syndrome where degenerating white matter fibre bundles leads to deterioration in the integration and communication between brain regions. Connectomics allows study of vivo connectivity elucidates how changes network. Although some studies have shown evidence alteration structural AD cognitively normal individuals (CN), large...
