Purification and characterization of a better-behaved Alzheimer’s disease protein
Alzheimer’s Disease (AD) is an incurable disease that causes memory, reasoning and thinking to deteriorate over time. AD is marked by brain atrophy and plaque-like deposits of a small peptide called amyloid beta (Aß) outside of brain
The use of olfactory neuronal precursors for antemortem Alzheimer’s Disease diagnosis
Alzheimer’s disease (AD) is a disabling and progressive illness that causes a high social cost and economic burden. Current diagnosis has been done by clinical appreciation based on the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) and
The suitability of scopolamine as an Alzheimer’s model
Alzheimer’s disease is the most common cause of dementia. About 50 million people worldwide have Alzheimer’s disease or a related form of dementia. Alzheimer’s disease is a terminal illness affecting mostly the elderly above the age of
Extracellular cytochrome c: a novel damage-associated molecular pattern (DAMP) of the brain
Cytochrome c (CytC) is a protein that is normally located inside mitochondria where it participates in the energy-generating processes of cells. Since mitochondria are essential for life, these CytC-containing organelles are found in most animal cells. The
Most common behavioral problems in people with dementia
With people all over the world living longer, more and more of them develop problems with brain functions. Some of these problems are mild, e.g. slight forgetfulness, but some may interfere with their daily activities, such as
A mass spectrometry view of the interaction of Alzheimer’s disease proteins with an anti-aggregation compound
Alzheimer’s disease is a neurodegenerative disease that has been studied extensively over the last four decades. Millions of people worldwide are affected by this disease, and because our population is growing older, this disease is becoming alarmingly
Biomarkers for Alzheimer’s disease diagnosis: an eye on retinal inflammation
Alzheimer’s disease is one of the most common neurodegenerative disorders. Alzheimer’s disease cases are constantly increasing worldwide due to population aging. Typical symptoms of the disease include memory loss, cognitive deficits, personality and behavior modifications. At the
Repetitive DNA in the ABCA7 gene influences Alzheimer’s disease
Dementia, which is characterized by decline of memory or other cognitive traits to the extent that a person’s daily functioning is affected, is one of the most important global health challenges of our time. Approximately 50 million
Why iron and copper may be harmful to the aging brain
Similar to other organs, brain function declines with age. Furthermore, age is the single greatest risk factor for Alzheimer’s disease as well as other neurodegenerative diseases. Both iron and copper increase in the brain with aging and
Acting in mechanisms of aging to delay/prevent Alzheimer’s disease
Alzheimer’s disease (AD), a severely debilitating and ultimately fatal brain disorder, affects millions worldwide. To date, clinical efforts to find a cure or adequate treatment have met with dispiriting failure. The disease is now on an ominous
Reversibility of Aβ oligomer neurotoxicity: Insights into the treatment of Alzheimer’s disease
Alzheimer’s disease (AD), the most common neurodegenerative dementia disorder, causes memory impairment and other cognitive deficits. AD is neuropathologically characterized by senile plaques and neurofibrillary tangles, which are composed of amyloid β-protein (Aβ) and phosphorylated tau proteins,
Intrinsic human multidrug transporters as helpers against Alzheimer’s Disease
The cause(s) of Alzheimer’s Disease (AD) is still unknown, so is a proper method for diagnosis. AD is a widely occurring form of neurodegeneration that is considered to affect 47 million people worldwide, according to the World
Determination of regions involved in amyloid fibril formation for Aβ(1-40) peptide
Mechanisms of amyloid formation of Aβ peptide are studied intensively. Determination of regions responsible for aggregation of the peptide and formation of amyloid fibrils is one of the primary aims in studying the formation of such structures.
Conformal invariants for landmark curve based brain morphometry analysis
Abnormal structural changes measured on cortical surfaces are important biomarkers for Alzheimer’s disease (AD). In brain imaging research, landmark curves are usually delineated on cortical surfaces to represent significant sulcus and gyrus patterns. Landmark curves are widely
Adolescent exposure of MDMA potentiates one of the hallmarks of Alzheimer’s disease
3,4 Methylenedioxymethamphetamine (MDMA) is an amphetamine derivative widely consumed by adolescents, which has been described that produces oxidative stress in neurons such as dopaminergic neurons. Moreover, many patients with Alzheimer’s disease develop extrapyramidal symptoms due to alterations
Determination of the size of folding nuclei of fibrils formed from Aβ(1-40) peptide
One of the most important models for studying amyloid fibril formation is the Aβ peptide, aggregates of which form plaques in the course of Alzheimer`s disease. Formation of Aβ aggregates goes through the nucleation mechanism with exponential
Amyloid specific antibodies are not necessary to detect amyloid plaques in Alzheimer’s disease
Alzheimer’s disease (AD) is an age-related neurological disorder which impairs learning, memory, and cognition. Gradual accumulation of amyloid beta protein (Aβ) is one of the hallmark pathologies of this disease. Early detection of the presence of Aβ
Eat your carrots – otherwise your risk of getting Alzheimer’s might increase!
Vitamin A is an important component of human nutrition, delivered by e.g. liver or fish dishes, but also fruits and vegetables, such as carrots. It is not only needed for development of organs and tissue (e.g. the
Chromosome gains and losses in the human brain are probably less important than previously thought
In general, each human cell contains 46 chromosomes: 23 chromosomes from each parent. Before a cell divides all chromosomes are duplicated. The cell has several mechanisms to ensure that during cell division the chromosomes are evenly distributed
