Patterns of reflux in patients with CEAP C2 disease compared to patients with C6 venous ulceration.

Objective: CEAP categorizes patients based on disease progression and severity. Whether disease severity is associated with specific patterns of reflux is currently unknown. We hypothesize that patterns of reflux in patients with C2 and C5/6 disease will differ.

Distinct subcellular localization of tau and alpha-synuclein in lewy body disease.

Lewy bodies and neurofibrillary tangles, composed of α-synuclein (α-syn) and tau, respectively, often are found together in the same brain and correlate with worsening cognition. Human postmortem studies show colocalization of α-syn and tau occurs in Lewy bodies, but with limited effort to quantify colocalization. In this study, postmortem middle temporal gyrus tissue from decedents (n = 9) without temporal lobe disease (control) or with Lewy body disease (LBD) was immunofluorescently labeled with antibodies to phosphorylated α-syn (p-α-syn), tau phosphorylated at Ser202/Thr205 (p-tau), or exposure of tau's phosphatase-activating domain (PAD-tau) as a marker of early tau aggregates.

Examining homology between MPXV and immunogenic VACV-derived peptides.

The mpox virus (MPXV) came to global attention with the 2022 global outbreak. Current vaccination and post-exposure prophylaxis against MPXV consists of live vaccinia whole virus-based vaccines including ACAM2000®, JYNNEOS™, and LC16m8 originally developed against smallpox. Here, we analyzed 152 vaccinia-derived peptides we identified by mass spectrometry for homology with MPXV-1 and MPXV-2 sequences to evaluate their potential relevance to MPXV-specific immunity.

3D Scanning of Surgical Specimens to Improve Communication Between Surgeon and Pathologist: A Head and Neck Pilot Study.

Successful surgical outcomes in head and neck cancer depend on the accurate identification of resection margins. Effective communication between surgeons and pathologists is critical, but is often jeopardised by challenges in sampling and orienting anatomically complex specimens. This pilot study aims to evaluate the use of 3D scanning of surgical specimens as a tool to improve communication and optimise the pathology sampling process.
