Abstract: The present invention concerns polymer particles made from poly(lactic-co-glycolic acid) (PLGA) polymer, poly(lactic-co-glycolic acid)-polyethylene glycol-poly(lactic-co-glycolicacid) (PLGA-PEG-PLGA) copolymer, or the mixture of same, combined with hyaluronic acid molecules or hyaluronic acid salts, and the method for preparing same. The present invention also concerns injectable pharmaceutical or cosmetic compositions comprising such polymer particles, the method for preparing such compositions, and the use thereof for medical purposes, in particular for the prevention and/or treatment of musculoskeletal diseases, diseases and traumatic conditions of the skin, oral disorders, vaginal mucosa dryness and urinary infections or cystitis, dryness of the eye membrane and eye infections, obesity, and the use of same to combat ageing of the skin and/or for repairing the dermal tissue (mesotherapy).

Abstract: The present invention relates to the use of warmers, or autonomous heat packs, for heating and maintaining a solution at a suitable temperature, for the period of time required to accomplish a chemical, biochemical or biological reaction, in particular in molecular biology or cell biology applications. Biology kits containing warmers are also part of this invention.
