Could one amino acid help explain why men tend to live shorter lives?

A UK Biobank cohort and Mendelian randomization study involving 272,475 participants linked higher circulating tyrosine with greater all-cause mortality and genetically predicted higher tyrosine with shorter lifespan. After accounting for phenylalanine, the relationship with shorter lifespan was clearest in men, while findings in women were less consistent, suggesting a potential sex-specific role for tyrosine in longevity.

Voltammetry and machine learning for real-time neurotransmitter detection

Anne Andrews (UCLA) explains how voltammetry and machine learning can track multiple neurotransmitters in real time, even with overlapping signals.

Perilla oil may curb platelet reactivity and inflammatory signaling in smokers

An eight-week randomized trial found that daily perilla oil increased plasma and red-cell ALA, plasma EPA, and platelet closure time in healthy smokers. Perilla oil also reduced TNF-α and TBX21 gene expression, but it did not improve broader coagulation, lipid, endothelial, or postprandial markers.

Omalizumab beats multiallergen oral immunotherapy in multifood allergy trial

Omalizumab demonstrates higher treatment success for multifood allergies compared to oral immunotherapy, with fewer adverse events impacting patient retention.

Two heart nerve cell types sustain cardiac stability in mice

Researchers identified two major intrinsic cardiac neuron populations in mice: Npy-positive neurons regulate parasympathetic heart rate control and support coronary perfusion, while Ddah1-positive neurons help maintain electrical stability during extreme stress. Removing Npy-positive neurons caused fatal cardiac failure, whereas loss of Ddah1-positive neurons increased susceptibility to malignant arrhythmias and sudden cardiac arrest under stress.

New study links overactive C1 neurons to prolonged anxiety responses

Anxiety disorders affect more than 300 million people globally. Several brain regions have been linked to anxiety, but how these regions connect has been poorly understood.

Review explores diagnosis and management of perioperative anaphylaxis during anesthesia

Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.

Slow and steady wins: Low-dose peanut immunotherapy safely desensitizes 82% of preschoolers in landmark trial

A Swedish randomized trial found that slow up-dosing peanut oral immunotherapy with a low maintenance dose helped 82% of preschool children achieve sustained peanut tolerance after three years. The approach proved safer than conventional protocols, with severe reactions uncommon and strong family adherence throughout treatment.

New biorepository approach advances research on sudden cardiac arrest

A cutting-edge University of Cincinnati College of Medicine study has shown how emergency medicine researchers can partner with community emergency medical services nationwide to investigate the causes of sudden cardiac arrest.

Anaphylaxis antidote underprescribed for schoolchildren in England

Less than half of schoolchildren in England who are at risk of a serious and potentially life-threatening allergic reaction (anaphylaxis) to food were prescribed the antidote-an adrenaline [epinephrine] autoinjector, or AAI for short-finds an analysis of national prescribing data, published online in the Archives of Disease in Childhood.

Could belonging be a biological shield? Researchers uncover aging clues

Researchers analyzing over 2,100 adults from the MIDUS cohort found that individuals with higher cumulative social advantage, spanning community ties, family relationships, and religious support, showed slower biological aging and lower systemic inflammation. The findings suggest that long-term social resources may become biologically embedded, influencing molecular pathways linked to longevity.

Asthma and multiple allergies raise the risk of failed oral food challenges

Research shows asthma and multi-food allergies elevate the odds of reactions in oral food challenges, emphasizing the importance of careful patient selection.

Intranasal adrenaline can be as effective as the EpiPen

Instead of stabbing yourself, or someone else, in the thigh with a needle to deliver a dose of adrenaline to counter anaphylactic shock, would it not be easier to use a nasal spray instead?

Gut mast cells produce key molecules driving food allergy anaphylaxis

Food allergies affect more than half a billion people worldwide. In severe cases, even a small bite of the wrong food can trigger anaphylaxis - a rapid, body-wide allergic reaction that can cause difficulty breathing, a dangerous drop in blood pressure and even death.

AI-powered sweat sensor predicts anxiety before symptoms appear

Researchers have developed Stressomic, a wearable microfluidic biosensor that sequentially measures cortisol, epinephrine, and norepinephrine in sweat at six-minute intervals. The device distinguishes physical from psychological stress and predicts anxiety levels using machine learning.

MIT develops implantable device to automatically release emergency glucagon

For people with Type 1 diabetes, developing hypoglycemia, or low blood sugar, is an ever-present threat. When glucose levels become extremely low, it creates a life-threatening situation for which the standard treatment of care is injecting a hormone called glucagon.

Study reveals top reasons schools call emergency medical services

The three most common reasons schools called emergency medical services (EMS) were for neurological crises such as seizures, psychiatric conditions or substance abuse, and trauma related injuries, according to data from the national EMS registry analyzed by researchers from Ann & Robert H. Lurie Children's Hospital of Chicago.

New consensus report aims to improve anaphylaxis treatment worldwide

A groundbreaking consensus report on anaphylaxis – the severe reaction some people experience from bee stings, peanut butter exposures, medications, and the like – has been released by the Global Allergy and Asthma Excellence Network (GA2LEN) and recently published in The Journal of Allergy and Clinical Immunology.
