Matrix vesicle-inspired delivery system based on nanofibrous chitosan microspheres for enhanced bone regeneration.

Inspired by the initial mineralization process with bone matrix vesicles (MVs), this study innovatively developed a delivery system to mediate mineralization during bone regeneration. The system comprises nanofibrous chitosan microspheres (NCM) and poly (allylamine hydrochloride)-stabilized amorphous calcium phosphate (PAH-ACP), which is thereafter referred to as NCMP. NCM is synthesized through the thermal induction of chitosan molecular chains, serving as the carrier, while PAH-ACP functions as the mineralization precursor.

Hypothyroidism Due to Thyroid Amyloidosis Simultaneously With AL Renal Amyloidosis to Give Better Idea of Association of the Two Conditions.

Primary amyloidosis (AL type) is a systemic disease that can lead to structural and functional damage to organs and tissues such as the kidney, heart and liver with non-specific symptoms. Most of the affected patients develop thyroid infiltration and thus diffuse enlargement of the thyroid gland, while cases leading to hypothyroidism are exceedingly rare. Some researchers have analyzed thyroid function in newly diagnosed patients with AL amyloidosis, and found that the incidence of overt hypothyroidism is only 7%.
