by James Ives, M.Psych. (Editor) A group of Hokkaido University researchers has developed a paper-based device that can easily and cheaply measure lithium ion concentration in blood, which could greatly help bipolar disorder patients. Lithium carbonate is used for treating bipolar disorder, a mental health condition that causes extreme mood swings. But using this drug...

Local inflammatory cells are characteristic for advanced multiple sclerosis
In the brains of people that suffer from long-term multiple sclerosis (MS), inflammatory cells are not entering the brain via the bloodstream anymore. Instead, the cells arise from local memory cells in the brain. Nina Fransen and her colleagues of the Netherlands Institute for Neuroscience show this in a recently published article in the scientific...

3D-printed device finds ‘needle in a haystack’ cancer cells by removing the hay
GEORGIA INSTITUTE OF TECHNOLOGY Finding a handful of cancer cells hiding among billions of blood cells in a patient sample can be like finding a needle in a haystack. In a new approach enabled by 3D-printed cell traps, researchers are removing the hay to expose the cancer cells. Trapping the white blood cells – which...

Perturbed Genes Regulating White Blood Cells Linked to Autism Genetics and Severity
Posted Today Researchers at University of California San Diego School of Medicine say they are getting closer to identifying the mechanisms of autism spectrum disorder (ASD) and biomarkers that can aid in early diagnosis and predictions of symptom severity. A team of scientists analyzed blood gene expression data from 302 one- to four-year-old boys with...

Blood-brain barrier damage occurs even with mild head trauma — Ben-Gurion U study
AMERICAN ASSOCIATES, BEN-GURION UNIVERSITY OF THE NEGEV BEER-SHEVA, ISRAEL…September 25, 2019 – In a new study of adolescent and adult athletes, researchers at Ben-Gurion University of the Negev, Stanford University and Trinity College in Dublin have found evidence of damage to the brain’s protective barrier, without a reported concussion. For the first time, the researchers were able to detect damage to the blood-brain barrier (BBB), which protects the brain from...

Study gives new perspective on production of blood cells and immune cells
by University of California – Santa Cruz New findings support a model of blood cell differentiation in which the production of red blood cells is the default fate of hematopoietic stem cells, which can also produce platelets and white blood cells. Credit: Boyer et al., 2019 A healthy adult makes about 2 million blood cells every...

Vitamin B3 analogue boosts production of blood cells
IMAGE: MITOCHONDRIA IN HEMATOPOETIC STEM CELLS, VISUALIZED WITH A GREEN FLUORESCENT DYE view more CREDIT: N. VANNINI, LUDWIG INSTITUTE FOR CANCER RESEARCH Stem cell-based therapies are becoming more and more common, especially in the treatment of blood cancers like lymphoma and leukemia. In these cases, the patient’s cancerous blood stem cells are removed and replaced with new, healthy ones....

Too much of this in the blood could predict unhealthy aging
A hormone found in the blood that’s commonly linked to heart disease also might signal when someone is more likely to grow weaker or lose their ability to balance before they’re 70. People in their early 60s with higher-than-normal levels of brain natriuretic peptide, or BNP, walked slower and were less able to raise themselves...

Human blood cells can be directly reprogrammed into neural stem cells
Scientists from the German Cancer Research Center (DKFZ) and the stem cell institute HI-STEM in Heidelberg have succeeded for the first time in directly reprogramming human blood cells into a previously unknown type of neural stem cell. These induced stem cells are similar to those that occur during the early embryonic development of the central...

Modeling mitosis: how combining proteins could help in understanding dividing cells
A new interactive map of the proteins involved in cell division gives the ability to track how groups of proteins interact to drive the process of mitosis. Researchers from the European Molecular Biology Laboratory (EMBL; Hamburg division, Germany) have created a 4D computer model for mitosis, allowing for the real-time tracking of the proteins involved....
