Wearable Microneedle Sensor Enables In Vivo Bioanalysis of Cardiac Biomarkers

Researchers developed a microneedle electrochemiluminescence device that measured cardiac troponins in interstitial fluid at 30-minute intervals and detected cTnI down to 21.3 fg/mL in artificial interstitial fluid. In 15 rats and 1 pig, researchers recorded biomarker trends broadly consistent with serum ELISA results, although the wired, single-target prototype has not been tested in humans.

AI-Assisted Paper Test Measures Three Cardiac Biomarkers in 23 Minutes

Researchers developed an AI-assisted dual-mode paper assay that measures cTnI, CK-MB, and NT-proBNP from 50 µL of serum in 23 minutes. In single-site analytical validation, neural networks quantified the three biomarkers across distinct concentration ranges, supporting further development for multiplexed cardiac testing at the point of care.

Study Uncovers Two Distinct Embryonic Macrophage Populations with Different Repair Abilities

In leukemia's most aggressive forms, the blood cell factories in our bone marrow falter. Instead of dividing and multiplying at their usual prolific pace, generating hundreds of billions of new cells daily, some precursor cells stall out at an immature stage.

New Research Links CALB2 Gene to Mechanoresistance in Metastatic Prostate Cancer

When a cancer cell leaves the original tumor to spread to a new, far away location, it first has to survive what most cells cannot: periodic high force moments in the vessels and heart of up to 5,000 dynes per centimeter squared as it circulates throughout the body.

Chemotherapy Leaves Distinct DNA Changes in Childhood Tumors

Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids).

Engineered Mice Carrying the Genetic Variant Develop Excessive Sweating

Johns Hopkins Medicine researchers have identified a genetic driver of primary idiopathic hyperhidrosis, a chronic condition that causes excessive sweating, providing some of the strongest evidence to date that the disorder can originate in the nervous system and may be treatable with targeted therapies.

Female Hearts Rely on Molecular Safeguard to Avoid Failure

Men and women are not born with the same risk of heart disease, and for decades scientists have struggled to explain why. A new study from the University of North Carolina at Chapel Hill, published in Genes & Development, offers a striking answer: the female heart depends on a molecular safeguard that the male heart can largely do without - and when that safeguard is removed, female hearts fail while male hearts keep beating.

Bullfrog Protein Saxiphilin Acts as Effective Antidote for Marine Saxitoxin

The "red tide" algal blooms that are becoming more frequent along the Pacific coast produce one of the most potent neurotoxins known: saxitoxin, or STX.

Study Identifies Immune Cell Failures as Aging Drivers

We may age at different rates, but none of us escapes aging.

Crucial X Chromosome Protein Protects Female Hearts From Fatal Failure

Men and women are not born with the same risk of heart disease, and for decades scientists have struggled to explain why.

UC Riverside Identifies How Tick Borne Viruses Evade Immunity

A study led by a University of California, Riverside biomedical scientist shows how a family of tick-borne viruses known as orthonairoviruses can evade immune defenses, offering important insights into emerging infectious disease threats and the potential pandemic risk posed by these viruses.

New CRISPR Atlas Details How Every Gene Influences Stem Cells

A team led by bioengineers at the University of California San Diego has developed a genome-scale reference map that details how individual genes control the functions and identities of human stem cells.

New Science Study Reveals Genetic Secrets of High Altitude Mice Survival

Even for elite mountain climbers, reaching the summits of the Central Andes is an arduous undertaking. Atop these peaks - some of which reach elevations of almost 7,000 meters - it's a perennial winter, with temperatures rarely rising above freezing.

New Cellular Nanodiscs Protect Major Organs From Severe Bloodstream Infections

Tiny particles made from the membranes of human immune cells could offer a promising new way to fight fungal infections that are becoming harder to treat.

Microtubule-Stabilizing Protein Camsap3 Proves Essential for Female Fertility

Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles.

Scientists Identify Biological Link Between Low Birth Weight and Chronic Disease

Researchers have long sought to discover why babies who weigh less than expected at birth, a condition known as small for gestational age, or SGA, are at higher risk for heart, lung and metabolic diseases as adults.

Stem T Cells Replenish the Immune System During Chronic Infections and Diseases

T cells are an elite fighting force of the immune system, seeking out and destroying diseased cells. But in a prolonged campaign against a chronic condition - like a viral infection, or cancer - the body needs a steady supply of these killer troops. Where and how these killer troops are generated has been a mystery.
