In-plane electrical conductivity of PEDOT:PSS/Halloysite composite thin films.

PSS has found numerous applications in the field of advanced materials, especially in the development of organic electronics. Embedding nanoparticles into the polymer matrix has emerged as an effective strategy to modify the properties of PEDOT:PSS and develop advanced functional composites. Over the past decade, Halloysite nanotubes (HNT) have garnered significant interest and utility as nanofillers and/or templates due to their unique physical-chemical properties, small size, relatively low cost, and large availability.

Belzutifan in Individuals with von Hippel-Lindau Retinal Hemangioblastomas: Institutional Experience and Review of the Literature.

Introduction: The systemic HIF-2 alpha inhibitor, belzutifan, has been approved for use in patients with von Hippel-Lindau disease (VHL)-associated renal cell carcinoma, central nervous system (CNS) hemangioblastomas, and pancreatic neuroendocrine tumors. This drug has also shown promise in controlling VHL retinal hemangioblastomas (RHs), but little work has been published on the use of the drug in this setting.

Methods: We conducted a retrospective review of patients with VHL-associated RHs followed by the retina service at our institution who were treated with systemic belzutifan.

Pseudo-pigmented choroidal schwannoma with extraocular extension in an elderly patient.

Purpose: To describe a rare case of clinically pigmented choroidal schwannoma with extraocular extension in an elderly patient.

Observations: We report a case of a 79-year-old Black male who presented with a clinically pigmented, juxtapapillary choroidal tumor with concern for extraocular extension on standardized ocular echography. The lesion was concerning for choroidal melanoma with extraocular extension.

A clinical metagenomic study of biopsies from Mexican endophthalmitis patients reveals the presence of complex bacterial communities and a diversity of resistance genes.

Infectious endophthalmitis is a severe ophthalmic emergency. This infection can be caused by bacteria and fungi. For efficient treatment, the administration of antimicrobial drugs to which the microbes are susceptible is essential.

The virome of bubaline (Bubalus bubalis) tonsils reveals an unreported bubaline polyomavirus.

Water buffalo (Bubalus bubalis) farming is increasing in many regions of the world due to the species' ability to thrive in environments where bovine cattle would struggle. Despite water buffaloes being known for their resistance to diseases, there is a lack of data about the diversity of the microbiome of the species. In this study, we examined the virome diversity in palatine tonsils collected from animals from the island of Marajó, northern Pará state, Brazil, which harbors the largest bubaline flock in the country.
