Detecting Alzheimer’s disease in the blood using Digital ICA

Alzheimer’s disease

Researchers from Hokkaido University and Toppan have developed a method to detect build-up of amyloid β in the brain, a characteristic of Alzheimer’s disease, from biomarkers in blood samples. Alzheimer’s disease is a neurodegenerative disease, characterised by a gradual loss of neurons and synapses in the brain. One of the primary causes of Alzheimer’s disease is the accumulation of amyloid ...

How the mother’s mood influences her baby’s ability to speak

Up to 70 percent of mothers develop postnatal depressive mood, also known as baby blues, after their baby is born. Analyses show that this can also affect the development of the children themselves and their speech. Until now, however, it was unclear exactly how this impairment manifests itself in early language development in infants. In a study, scientists at the ...

Mother’s ultra-processed food intake linked to obesity risk in children; Unlikely during peripregnancy

ultra-processed foods

A mother’s consumption of ultra-processed foods appears to be linked to an increased risk of overweight or obesity in her offspring, irrespective of other lifestyle risk factors, suggests a US study. Researchers suggest that mothers might benefit from limiting their intake of ultra-processed foods, and that dietary guidelines should be refined and financial and social barriers removed to improve nutrition ...

b-type procyanidin-rich foods consumed in right amounts have multiple health benefits

B-type procyanidins

B-type procyanidins, made of catechin oligomers, are a class of polyphenols found abundantly in foods like cocoa, apples, grape seeds, and red wine. Several studies have established the benefits of these micronutrients in reducing the risk of cardiovascular diseases and strokes. B-type procyanidins are also successful in controlling hypertension, dyslipidemia, and glucose intolerance. Studies attest to the physiological benefits of ...

Human ‘blastoids’ offer medical hope but also deep ethical challenges

The study of blastoids, a research model of an early embryo derived from stem cells rather than from a father’s sperm or a mother’s egg, offers great hope for researchers investigating why pregnancies are lost at an early stage, what causes birth defects, and other topics related to early human development. Their use potentially avoids the challenges of scarcity and ...

‘Love hormone’ revealed to have heart healing properties in Humans like EpiPCs regenerate organs in zebrafish

The neurohormone oxytocin is well-known for promoting social bonds including trust, empathy, positive memories, processing of bonding cues, and positive communication and generating pleasurable feelings, for example from art, exercise, or intimacy. Now, researchers from Michigan State University show that in zebrafish and human cell cultures, oxytocin has yet another, unsuspected, function: it stimulates stem cells derived from the heart’s ...
