A heteropolysaccharide, designated JYP70-1, was extracted and purified from the fruits of Rosa laevigata, exhibiting a molecular weight of 1.90 × 10 g/mol. Structural analysis revealed that JYP70-1 was composed of eleven sugar residues, including α-l-Araf-(1→, →3)-α-l-Araf-(1→, →5)-α-l-Araf-(1→, →3,5)-α-l-Araf-(1→, →2,5)-α-l-Araf-(1→, →4)-α-d-Galp-(1→, →6)-β-d-Galp-(1→, →6)-α-d-Glcp-(1→, α-d-Glcp-(1→, →2)-α-d-Manp-(1→, and →3,6)-β-d-Manp-(1→.

This study estimates the impact of reducing household solid fuel dependence on the infant mortality rate (IMR) in developing countries, where traditional solid fuels such as firewood and coal are widely used. Utilizing panel data from 76 developing countries over the period 1990 to 2020, our findings indicate that IMR drops substantially as household reliance on solid fuels decreases. A 1% reduction in per capita solid fuel consumption is linked to an average 0.

Introduction: Diabetes mellitus often leads to bone metabolism disorders, hindering bone regeneration and delaying the healing of bone defects. β-Ecdysone, a plant-derived hormone known for its wide range of physiological activities, possesses hypoglycemic effects and promotes osteogenic differentiation. This study developed a composite PLGA slow-release scaffold loaded with β-ecdysone to enhance its bioavailability through topical administration and to investigate its potential to heal diabetic bone defects.
