Topical Probiotics: More Than a Skin Deep.

Skin, an exterior interface of the human body is home to commensal microbiota and also acts a physical barrier that protects from invasion of foreign pathogenic microorganisms. In recent years, interest has significantly expanded beyond the gut microbiome to include the skin microbiome and its influence in managing several skin disorders. Probiotics play a major role in maintaining human health and disease prevention.

Cobalt-Carbon Nanoparticles with Silica Support for Uptake of Cationic and Anionic Dyes from Polluted Water.

Silica-supported hierarchical graphitic carbon sheltering cobalt nanoparticles Co-HGC@SiO (1) were prepared by pyrolysis at 850 °C of [Co(phen)(HO)]SO·2HO complex with silica in the presence of pyrene as a carbon source under nitrogen atmosphere. Nanocomposites (2) and (3) were obtained by acid treatment of (1) with HCl and HF acid, respectively. The nanocomposites showed rough hierarchical carbon microstructures over silica support decorated with irregular cobalt nanospheres and nanorods 50 to 200 nm in diameter.

Ion-Triggered In Situ Gelling Nanoemulgel as a Platform for Nose-to-Brain Delivery of Small Lipophilic Molecules.

Intranasal route offers a direct nose-to-brain delivery via olfactory and trigeminal nerves and minimizes the systemic exposure of the drug. Although reliable and non-invasive, intranasal administration of lipophilic neuroprotective agents for brain targeting is still challenging. Literature focuses on naturally-derived compounds as a promising therapeutics for chronic brain diseases.

Cobalt-carbon/silica nanocomposites prepared by pyrolysis of a cobalt 2,2'-bipyridine terephthalate complex for remediation of cationic dyes.

Recently, carbon nanostructures have attracted interest because of their unique properties and interesting applications. Here, CoC@SiO-850 (3) and CoC@SiO-600 (4) cobalt-carbon/silica nanocomposites were prepared by solid-state pyrolysis of anthracene with Co(tph)(2,2'-bipy)·4HO (1) complex in the presence of silica at 850 and 600 °C, respectively, where 2,2'-bipy is 2,2'-bipyridine and tph is the terephthalate dianion. Moreover, Co(μ-tph)(2,2'-bipy) (2) was isolated and its X-ray structure indicated that cobalt(ii) has a distorted trigonal prismatic coordination geometry.
