Presence of SARS-CoV-2 in a Cornea Transplant.

Background: The SARS-CoV-2 pandemic has impacted tissue transplantation procedures since conjunctivas were found to be associated with coronavirus infection. Here, we investigated infection of a cornea graft from a COVID-19-positive donor.

Methods: In order to evaluate the presence of SARS-CoV-2 in the cornea graft we first carried out a qRT-PCR and then we investigated the presence of SARS-CoV-2 by fluorescence and electron microscopy.

Effects of hexanic extract of Serenoa repens (Permixon® 160 mg) on inflammation biomarkers in the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia.

Background: Chronic prostatic inflammation (CPI) could be a cause of symptomatic or complicated benign prostatic hyperplasia (BPH). In previous in vitro and in vivo studies, Hexanic Extract of Serenoa repens (HESr) namely Permixon(®) has demonstrated potent anti-inflammatory properties. With the aim to provide new insight onto HESr anti-inflammatory properties in human we explore its effect on CPI biomarkers in men with lower urinary tract symptoms (LUTS) related to BPH using a non-invasive method and investigate links between biomarkers and clinical symptoms.

Anti-inflammatory properties of Lipidosterolic extract of Serenoa repens (Permixon®) in a mouse model of prostate hyperplasia.

Background: Permixon®, the hexanic lipidosterolic extract of saw palmetto Serenoa repens (LSESr), has shown properties that highlight its benefit in the management of benign prostate hyperplasia (BPH). To address its actual anti-inflammatory potency, we used a unique pro-inflammatory mouse model of prostate hyperplasia involving prostate-specific over-expression of prolactin transgene (Pb-Prl).

Methods: Six month-old Pb-Prl males were administered with Permixon® per os at the daily dose of 100 mg/kg for 28 days.

The Cosmetics Europe strategy for animal-free genotoxicity testing: project status up-date.

The Cosmetics Europe (formerly COLIPA) Genotoxicity Task Force has driven and funded three projects to help address the high rate of misleading positives in in vitro genotoxicity tests: The completed "False Positives" project optimized current mammalian cell assays and showed that the predictive capacity of the in vitro micronucleus assay was improved dramatically by selecting more relevant cells and more sensitive toxicity measures. The on-going "3D skin model" project has been developed and is now validating the use of human reconstructed skin (RS) models in combination with the micronucleus (MN) and Comet assays. These models better reflect the in use conditions of dermally applied products, such as cosmetics.
