CSF Conversion Assay Identifies Lewy Body Disease Cognitive Impairment

Lewy body dementia, also known as dementia with Lewy bodies, is the second most common type of progressive dementia after Alzheimer's disease. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement (motor control). More...

Urinary Epidermal Growth Factor Investigated for Diabetes Nephropathy

Type 1 diabetes mellitus is an auto-immune metabolic disease with chronic hyperglycemia. For many patients with type 1 diabetes (T1DM), it is challenging to maintain near-normal glucose blood levels and to reduce the risk of both acute (hypoglycemia, ketoacidosis) and chronic microvascular (retinopathy, neuropathy and nephropathy) and macrovascular complications. More...

ALDOA and FH4 Antibodies Associated with Cerebrovascular Disease

Ischemic stroke, including transient ischemic attack (TIA) and cerebral infarction (CI), is the most globally recognized cerebrovascular disorder, and is a serious health problem in the aging society. CI is an episode of neurological dysfunction caused by focal brain infarction, often resulting in fatality and disability. Patients with TIA are at a high risk of CI. More...

APOE Gene Influences Alzheimer's Symptoms, Biomarkers in Down Syndrome

Individuals with Down syndrome (DS) constitute a population at ultrahigh risk of developing Alzheimer disease (AD) because of trisomy of chromosome 21, which harbors the amyloid precursor protein (APP) gene. More...

Elevated PlGF Levels Found with Acute Fatty Liver of Pregnancy

Acute fatty liver of pregnancy (AFLP) is a severe liver disorder unique to pregnancy, typically occurring after 30 weeks’ gestation. Although uncommon, with an estimated global incidence of 1 in 7,000 to 15,000 pregnancies, AFLP is a life-threatening disease for both mother and child. More...

Novel Adipokine Biomarker Reported for Insulin Resistance and Atherosclerosis

Diabetes Mellitus is a chronic condition occurring due to inadequate production or inadequate action of insulin, ultimately leading to hyperglycemia. Prediabetes, regarded as a precursor of diabetes, is a condition with elevated plasma glucose above normal levels, but below that of clinical disease. More...

Two Inflammatory Proteins Linked with Slower Cognitive Decline

Previous meta-analyses of case-control and prospective cohort studies showed that cytokines and inflammatory markers, such as interleukin-6 (IL-6), C-reactive protein (CRP), and others are elevated in Alzheimer's dementia cases and predicted incident of all-cause dementia. More...
