Chlamydial infections in free-ranging raptors presenting to a university veterinary medical teaching hospital (1993-2022).

Objective: To describe the prevalence, clinical findings, lesions, and risk factors associated with chlamydial infections in free-ranging raptors presented to a university veterinary medical teaching hospital.

Methods: Medical records retrospectively searched for raptors admitted from January 1993 through April 2022 were tested for Chlamydia spp infections using quantitative PCR (qPCR), immunohistochemistry, culture, and sequencing. Findings were collected and analyzed.

Bromelain Supplementation in the Management of Otitis Media with Effusion in Children.

Background/objectives: The respiratory system is prone to infectious diseases, especially in children below five years of age. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media with effusion (OME), an inflammatory process within the middle ear, which can lead to hearing loss. Treatment for these infections involves a combination of medication and symptom relief, depending on the severity and cause of the infection.

Enhancing immune response and survival in hepatocellular carcinoma with novel oncolytic Jurona virus and immune checkpoint blockade.

Members of the genus including Jurona virus (JURV) have emerged as promising immunotherapeutic agents, characterized by their tumor selectivity, fast kinetics, low seroprevalence, and minimal toxicity in humans. Here, we demonstrate that the administration of JURV leads to tumor regression in both hepatocellular carcinoma (HCC) xenograft and syngeneic models. Furthermore, our findings indicate that combining JURV and anti-PD-1 therapy reduced tumor burden and improved survival rates over JURV or anti-PD-1 alone in an orthotopic HCC model.

Application of Fluorescence- and Bioluminescence-Based Biosensors in Cancer Drug Discovery.

Recent advances in drug discovery have established biosensors as indispensable tools, particularly valued for their precision, sensitivity, and real-time monitoring capabilities. The review begins with a brief overview of cancer drug discovery, underscoring the pivotal role of biosensors in advancing cancer research. Various types of biosensors employed in cancer drug discovery are then explored, with particular emphasis on fluorescence- and bioluminescence-based technologies such as FRET, TR-FRET, BRET, NanoBRET, and NanoBiT.

Operative Fires: Variables Associated with Polymethylmethacrylate Flammability.

Background: Operative fires are rare but unforgettable events, with the potential for devastating outcomes. It is estimated that 650 operating room (OR) fires occur each year in the United States, with the use of electrocautery devices and polymethylmethacrylate (PMMA) as the primary ignition and fuel sources. There are several case reports of OR fires caused by PMMA and electrocautery in the literature, but, to our knowledge, no formal studies have been performed exposing the flammability of PMMA and how PMMA reacts to an electrocautery ignition source.
