Indocyanine green dyed gauze-guided minimum invasive surgery for anatomical landmarks and preventing gauze remnants: a pilot study.
Langenbecks Arch Surg
January 2025
Department of Chemical Science & Engineering, School of Materials and Chemical Technology, Institute of Science Tokyo, 2-12-1 Ookayama, Meguro-ku, Tokyo, 152-8552, Japan.
Purpose: We aimed to develop a novel fluorescent surgical gauze dyed with indocyanine green (ICG) to guide surgeons to the target anatomical destination during surgery for real-time navigation and to prevent gauze remnants after surgery.
Methods: Surgical gauze was dyed with an aqueous solution of ICG (5.0 × 10 mol L for Steraze, 1.
Influence of Parameters Used to Prepare Sterile Solutions of Poloxamer 188 on Their Physicochemical Properties.
Polymers (Basel)
December 2024
Institute of Theoretical and Experimental Biophysics RAS, Pushchino 142290, Russia.
The physicochemical properties of emulsions based on poloxamers (triblock copolymers of a hydrophobic polyoxypropylene chain and two hydrophilic polyoxyethylene chains) depend on the composition and preparation method. This study examined the impact of poloxamer P188 concentration, autoclaving mode, heating, and salt presence on the viscosity, particle size distribution, and morphology of particles using viscometric analysis, dynamic light scattering (DLS), and atomic force microscopy (AFM). It was shown that sample preparation affects the particle size and morphology but not the chemical composition of P188.

U.S. Geological Survey, Upper Midwest Water Science Center, 5840 Enterprise Drive, Lansing, MI 48911, USA.
Since late 2021, outbreaks of highly pathogenic avian influenza virus have caused a record number of mortalities in wild birds, domestic poultry, and mammals in North America. Wetlands are plausible environmental reservoirs of avian influenza virus; however, the transmission and persistence of the virus in the aquatic environment are poorly understood. To explore environmental contamination with the avian influenza virus, a large-volume concentration method for detecting infectious avian influenza virus in waterbodies was developed.

Purpose/hypothesis: The purpose of this study was to report increased infection rates after knee ligament reconstructions due to undetectable sterilization process errors leading to residual moisture, not limited to a specific surgical tool. It was hypothesized that (1) residual moisture on surgical tools due to autoclave overloading would not be detected by autoclave self-diagnostics, chemical and biological tests, or organoleptic assessment and (2) this kind of contamination may elevate infection rates, especially in knee intra-articular reconstruction procedures.
First Report of Causing Collar Rot of gilo in Ghana.
Plant Dis
January 2025
University of Ghana College of Basic and Applied Sciences, Biotechnology Centre, Accra, Greater Accra, Ghana;
African eggplant (Solanum aethiopicum gilo group) is a nutritious vegetable widely commercialized in Ghana. In the 2021 planting season (May-July), collar rot symptoms were observed on African eggplant on a farm at Domeabra, Legon, and Okumaning in the Central (N5° 48' 11″, W1° 26' 48″), Greater Accra (N5° 39' 34″, W0° 11' 34″) and Eastern (N6° 8' 34″, W0° 55' 59″) regions of Ghana, respectively. Disease incidence was 8-15% in the different farms.
