Obesity drugs: huge study highlights new health risks www.nature.com Jan. 21, 2025, 8:14 a.m.
Over about 3.5 years, Al-Aly and his colleagues tracked more than 200,000 people with diabetes on GLP-1 drugs and about 1.7 million people with diabetes using other blood-sugar-lowering medications. They tracked the effects of GLP-1 drugs on 175 health conditions. Compared with other diabetes medications, GLP-1 drugs were linked to a lower risk of dozens of conditions, including heart disease, stroke and kidney disease. They also lowered the risk of psychotic disorders by 18%, Alzheimer’s disease by 12%, and addiction disorders by an average of 13%.

Microplastics Have Been Found in the Human Brain. Now What? www.medscape.com Dec. 30, 2024, 9:29 a.m.
Measuring less than 5 mm in size, microplastics are formed over time as plastic materials break down but don’t biodegrade. Exposure to these substances can come through food, air, and skin absorption. While scientists are learning more about how these substances are absorbed by the body, questions remain about how much exposure is safe, what effect — if any — microplastics could have on brain function, and what clinicians should tell their patients.
Cancer reversed? New treatment converts tumor cells into healthy ones interestingengineering.com Dec. 28, 2024, 12:42 p.m.
The researchers created a digital twin of the gene network involved in the differentiation trajectory of normal cells. This computational model allowed them to simulate and analyze the intricate gene interactions that regulate cell differentiation. Through their simulations, the team pinpointed master molecular switches capable of steering cells from colon cancer back into a normal-like state. These findings were then validated through molecular experiments, cellular studies, and animal trials, demonstrating the effectiveness of this approach.
Challenges for the human immune system after leaving Earth www.nature.com Dec. 7, 2024, 2:31 p.m.
The evolutionary potential of the human immune system in space deals with many (yet unknown) obstacles. Such challenges include different pathogenic potential in microorganisms, altered immune response, low genetic variability, and large immune variability due to small population sizes to name a few. Reflecting on the evolutionary journey of immunity to a future in outer space reveals a crucial insight: the intricate and multifaceted actions and interactions within innate and adaptive immunity stem from a rigorous and enduring process of selection and deselection as described.

Ce nouveau test sanguin dépiste Alzheimer, 20 ans avant www.capretraite.fr Dec. 6, 2024, 4:32 p.m.
Ce dimanche 28 juillet, une nouvelle étude publiée dans la revue scientifique JAMA dévoile les très bons résultats d'un test sanguin pour diagnostiquer la maladie d'Alzheimer, 20 ans avant l'apparition des symptômes. Autrement dit, une simple prise de sang permettrait de prendre en charge plus tôt un patient atteint d'Alzheimer[1] et d'améliorer son quotidien. Ce test simple, non invasif et peu coûteux serait beaucoup plus efficace à un stade précoce qu'une consultation par un médecin ou même un neurologue. Explications.

Anti-inflammatory action of astaxanthin and its use in the treatment of various diseases www.sciencedirect.com Oct. 17, 2024, 10:20 a.m.
AST modulates inflammatory signaling pathways such as NF-kB and downregulates the expression of inflammatory cytokines. Although there are only a few clinical reports related to the protective effect of AST against inflammatory diseases, AST should be further characterized for its properties as a potential therapeutic strategy in combating inflammatory diseases.
Le groupe sanguin influence le risque d'AVC précoce, suggère une étude trustmyscience.com Oct. 14, 2024, 5:55 p.m.
Les accidents vasculaires cérébraux (AVC), principalement de nature ischémique, trouvent leurs racines dans divers facteurs, parmi lesquels l’athérosclérose occupe une place prépondérante. Cette pathologie se manifeste par la formation de plaques au sein des parois artérielles. Bien que les individus âgés soient généralement plus vulnérables aux AVC, une tendance inquiétante émerge : l’augmentation des cas d’AVC précoce. Une étude récente menée par des chercheurs américains révèle un lien insoupçonné entre ce phénomène et le groupe sanguin. Les conclusions de cette étude indiquent notamment que les individus du groupe sanguin A présentent un risque supérieur de subir un AVC précoce, en comparaison avec ceux des groupes sanguins B et O.

À 15 ans, Heman Bekele a inventé un savon qui traite le cancer de la peau creapills.com Sept. 2, 2024, 12:52 p.m.
Pour cela, ce petit génie en herbe a élaboré une formule chimique composée d’acide salicylique, d’acide glycolique et de trétinoïne, qui favorise l’activation de cellules indispensables au bon fonctionnement du système immunitaire et à la détection d’agents pathogènes potentiels. Il a ensuite ajouté ce mélange à une nanoparticule à base de lipides afin qu’elle ne se dissolve pas avec la mousse du savon et puisse pénétrer la peau.
Electroacupuncture Reduced Fibromyalgia-Pain-like Behavior through Inactivating Transient Receptor Potential V1 and Interleukin-17 www.mdpi.com Aug. 31, 2024, 2:17 p.m.
We found that FM-pain-like behavior induced in the ICS mice model elevated the plasma IL-17A and the brain IL-17RA. The results indicated that IL-17A plays a critical role in peripheral and central sensitization as well as neuroinflammation in the ICS FM mice model. Additionally, both EA and Trpv1−/− attenuated the plasma IL-17A and the brain IL-17RA. We also found that Trpv1−/− abolished the IL-17A, IL-17RA, and their downstream pathways, such as PI3K/Akt, MAPKs, and NF-κB. Therefore, IL-17A–IL-17RA might not induce neuroinflammation without TRPV1. Finally, our results indicated that EA relieved the ICS-induced FM mechanical and thermal pain-like behaviors maybe through the TRPV1–IL-17-related pathways in mice. It suggests that EA could lower the use of drugs and other additional pain treatment and is a potential therapeutic strategy in FM.
