Histological and molecular response of oral cavity tissues to Covid-19.

The world is still dealing with Covid-19 waves, and maintaining good oral health has systemic effects on overall health. This review's objective is to identify the main oral manifestations of this illness, its effects on oral tissues at their histological bases, their molecular cell mechanisms, and the relationship issues between Covid-19 outcomes and oral health conditions. The main sources of the review are research articles published from 2000 to 2023.

Boosting hair growth through follicular delivery of Melatonin through lecithin-enhanced Pickering emulsion stabilized by chitosan-dextran nanoparticles in testosterone induced androgenic alopecia rat model.

The strategy in this work was loading Melatonin (MEL), the powerful antioxidant photosensitive molecule, in novel Pickering emulsions (PEs) stabilized by chitosan-dextran sulphate nanoparticles (CS-DS NPs) and enhanced by lecithin, for treatment of androgenic alopecia (AGA). Biodegradable CS-DS NPs dispersion was prepared by polyelectrolyte complexation and optimized for PEs stabilization. PEs were characterized for droplet size, zeta potential, morphology, photostability and antioxidant activity.

The Prospective Effect of Cinnamon and Chia on Submandibular Salivary Glands After Ciprofloxacin Administration in Albino Rats (Histological, Histochemical, and Ultrastructural Study).

Ciprofloxacin (CPFX) is potent fluoroquinolone but has severe side effects. Cinnamon (CIN) and chia seeds are potent antioxidants. The current work aimed to compare the effect of CIN extract and chia seeds on CPFX-treated submandibular salivary glands (SMGs).

Spray-Dried Rosuvastatin Nanoparticles for Promoting Hair Growth.

In this research, we examined the effect of rosuvastatin calcium-loaded nanoparticles on the hair growth-promoting activity on Albino rats. Nanoparticles were prepared using 2:1 weight ratio of drug to methyl-β-cyclodextrin with 10, 20, and 30% stabilizers (phospholipid, polyvinyl pyrrolidone K30, and Compritol 888 ATO) using nanospray dryer. Subsequently, the prepared nanoparticles were evaluated for their process yield, particle size, polydispersity index, zeta potential, and in vitro drug release as well as in vivo studies.
