Hamilton's PRP-1 column detected bisphenol derivatives in "BPA-free" bottles. Leaching occurred with heat or ethanol exposure. Repeated washing with hot water or 40% ethanol removed derivatives without damaging bottles, ensuring safer use.
A study reveals that common pesticides and industrial chemicals inhibit gut bacteria, highlighting risks to health and the need for revised safety assessments.
Innovative sweat sampling techniques could revolutionize diagnostics, offering insights into glucose levels and environmental toxins with minimal discomfort.
Replacing beef with a plant based beef substitute for six days changed the fatty acid composition of human milk, increasing medium chain saturated fats and lowering key long chain polyunsaturated fats such as arachidonic acid. These biochemical shifts occurred without changes in maternal weight, appetite, glucose patterns or infant milk intake.
MIT researchers developed a compact band-pass Raman spectroscopy device that noninvasively tracks glucose through the skin in under a minute using physically interpretable optical signals. In a pilot study and tissue phantom validation, the system showed glucose measurements comparable to commercial continuous glucose monitors, supporting further clinical evaluation.
In adults with stage IIIb–IV chronic kidney disease, the constipation drug lubiprostone did not reduce gut-derived uremic toxins but preserved creatinine-based kidney function over 24 weeks. The benefit was linked to microbiome remodeling, increased polyamine production, and improved mitochondrial function rather than toxin lowering.
