Gold nanoparticles and angiogenesis: molecular mechanisms and biomedical applications
Global regulatory frameworksespecially the ICH S1 series guidelinesrequire structured carcinogenicity assessment: ICH S1A/S1B/S1C define when lifetime rodent studies are required Emphasis on hazard identification rather than direct human prediction Adoption of Weight-of-Evidence (WoE) approaches in ICH S1B(R1) The updated S1B(R1) guideline specifically encourages: Integration of mechanistic, exposure, and translational data Reduced reliance on 2-year rodent bioassays when justified Greater emphasis on human relevance and multi-factor evidence This shift reflects a broader regulatory evolution toward mechanism-based safety assessment rather than purely animal-driven hazard signals
In a retrospective cohort study including 7,044 patients with T2D, obesity (BMI 27 kg/m 2 ) and HFpEF, combination therapy with an SGLT2i and GLP-1 RA showed a lower risk of HF exacerbation, all-cause emergency department visits and new-onset kidney injury compared with patients only receiving SGLT2i
However, if the reaction seems severe or worsens over time, its vital to reach out to your healthcare provider
GLP-1 medications work through several complementary mechanisms: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner, which helps lower blood sugar levels Suppressing glucagon release , thereby reducing hepatic glucose production Slowing gastric emptying , which prolongs satiety and reduces appetite Acting on appetite centres in the brain , leading to reduced caloric intake and weight loss Commonly prescribed GLP-1 receptor agonists available in the UK include semaglutide (Ozempic, Wegovy, Rybelsus [oral form]), dulaglutide (Trulicity), liraglutide (Victoza, Saxenda), and exenatide (Byetta, Bydureon)
