Slightly viscous dispersions of mucoadhesive polymers as vehicles for nasal administration of dopamine and grape seed extract-loaded solid lipid nanoparticles.

With the aim to find an alternative vehicle to the most used thermosensitive hydrogels for efficient nanotechnology-based nose-to-brain delivery approach for Parkinson's disease (PD) treatment, in this work we evaluated the Dopamine (DA) and the antioxidant grape seed-derived pro-anthocyanidins (Grape Seed Extract, GSE) co-loaded solid lipid nanoparticles (SLNs) put in slight viscous dispersions (SVDs). These SVDs were prepared by dispersion in water at low concentrations of mucoadhesive polymers to which SLN pellets were added. For the purpose, we investigated two polymeric blends, namely Poloxamer/Carbopol (PF-127/Carb) and oxidized alginate/Hydroxypropylmethyl cellulose (AlgOX/HPMC).

Relationship between Fat Status, Stage of Gonadal Maturity and Hormonal Variation of (C.L. Brehm, 1831) Wintering in Apulia during 2018-2020.

In this study, we aimed to evaluate the development of the fattening condition and the reproductive status of the song thrush from December to February. For this purpose, the chemical and fatty acid compositions of the pectoral muscle were analyzed in relation to the fattening state of the birds. Moreover, their reproductive activity was evaluated via the anatomical and pathological examination of tissues and through the assessment of sex steroid profiles.

Effect of rearing system (free-range vs cage) on gut and muscle histomorphology and microbial loads of Italian White breed rabbits.

Objective: The growing consumers' interest on animal welfare has raised the request of products obtained by alternative rearing systems. The present study was conducted to assess the influence of housing system on gut and muscle morphology and on microbial load in rabbits reared under free-range (FR) and cage system (CS).

Methods: A total of forty weaned (35 days of age) male Italian White breed rabbits were allotted according to the rearing system, and at 91 days of age were randomly selected and slaughtered for the morphological evaluation of tissue from duodenum and longissimus lumborum.

Immunohistochemical, pharmacovigilance, and omics analyses reveal the involvement of ATP-sensitive K channel subunits in cancers: role in drug-disease interactions.

ATP-sensitive-K+ channels (KATP) are involved in diseases, but their role in cancer is poorly described. Pituitary macroadenoma has been observed in Cantu' syndrome (C.S.
