Tailoring formulation for enhanced phage therapy in canine otitis externa: a cocktail approach targeting Pseudomonas aeruginosa and Staphylococcus pseudintermedius.

Canine otitis externa, characterized by the involvement of diverse bacterial species, notably Pseudomonas aeruginosa and Staphylococcus pseudintermedius, necessitates antibiotic administration as the primary therapeutic approach; however, prolonged treatment often precipitates antibiotic resistance. Therefore, the application of bacteriophages as antimicrobial agents has been of interest recently. However, phage therapy has limitations; its efficacy depends on the lytic capacity of the phage and the emergence of phage resistance, which can be overcome by using phage cocktails.

Optimization of the large-scale production for Erwinia amylovora bacteriophages.

The nasotracheal tube (NTT) is frequently used in oral and maxillofacial surgery and is generally considered a safe means of protecting the airway while ensuring an adequate surgical field. The most common complication associated with NTT is epistaxis, and only a few cases of foreign body obstruction have been reported. In this case report, the authors aimed to highlight the potential for NTT obstruction following surgery.

Novel Gammaherpesvirus Infections in Narrow-Ridged Finless Porpoise () and False Killer Whales () in the Republic of Korea.

A female narrow-ridged finless porpoise () stranded on a beach on Jeju Island showed epithelial proliferative skin lesions on its body. Two false killer whales (), caught using nets near Gangneung and Samcheok, respectively, had multiple plaques on their penile epidermis. Histological examination of the epidermis revealed that all the lesions had common features, including accentuated rete pegs, ballooning changes, and eosinophilic intranuclear inclusion (INI) bodies.

Squamous Cell Carcinoma Arising From Epidermal Cyst: A Case Series of 9 Patients With a Literature Review.

Epidermal cysts are among the most common benign subcutaneous tumors. However, malignant transformation of benign epidermal cysts into squamous carcinomas has been reported. Owing to its low incidence rate, the clinical and pathological features of this condition are not well understood.

Anti-intercellular adhesion molecule 1 monomaintenance therapy induced long-term liver allograft survival without chronic rejection.

Calcineurin inhibitors (CNIs) are essential in liver transplantation (LT); however, their long-term use leads to various adverse effects. The anti-intercellular adhesion molecule (ICAM)-1 monoclonal antibody MD3 is a potential alternative to CNI. Despite its promising results with short-term therapy, overcoming the challenge of chronic rejection remains important.

Comparative Analysis of Antibacterial and Wound Healing Activities of Chitosan and Povidone-Iodine-Based Hydrogels.

Purpose: This study aimed to compare the antibacterial and wound healing efficacies of chitosan hydrogel with povidone-iodine (PI) hydrogel.

Methods: The in vitro antibacterial activities of chitosan and PI hydrogels against Staphylococcus aureus and Escherichia coli were evaluated. Nine 6- to 8-week-old male Sprague-Dawley rats were divided into plain, PI, and chitosan hydrogel groups.

Adhesive Bowel Obstruction (ABO) in a Stranded Narrow-Ridged Finless Porpoise ().

In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted with adhesive bowel obstruction (ABO), a life-threatening condition that has scarcely been reported in cetaceans. Diagnosis of ABO was confirmed via radiological and clinical assessments. Post-mortem computed tomography and necropsy revealed ABO between two loops of the jejunum at the L8 level.

Fatal upper aerodigestive tract obstruction in an East Asian finless porpoise (Neophocaena asiaeorientalis sunameri): findings in post-mortem computed tomography.

The present case report aims to outline the post-mortem findings of an East Asian finless porpoise with upper aerodigestive tract obstruction using different post-mortem computed tomography (PMCT) visualization techniques and discusses the potential cause of death of this individual. A dead-stranded adult male East Asian finless porpoise was recovered from the Northern coast of Jeju Island, Republic of Korea. The carcass was frozen in Jeju National University within 2 h upon first reported.

A new era of macrophage-based cell therapy.

Macrophages are essential innate immune cells found throughout the body that have protective and pathogenic functions in many diseases. When activated, macrophages can mediate the phagocytosis of dangerous cells or materials and participate in effective tissue regeneration by providing growth factors and anti-inflammatory molecules. Ex vivo-generated macrophages have thus been used in clinical trials as cell-based therapies, and based on their intrinsic characteristics, they outperformed stem cells within specific target diseases.

A modified induced membrane 2-stage technique using a thoracodorsal artery perforator free flap followed by vascularized or non-vascularized free fibular transfer for the treatment of complex bone infection with concomitant severe soft tissue lesion-A case series of 9 cases.

Treatment of post-traumatic complex bone infection is very challenging. The two principal bone reconstruction approaches are the single-stage vascularized bone graft technique and the two-stage induced membrane technique (IMT). Here we introduce a modified 2-stage induced membrane technique (MIMT) for complex long bone infection with a major bone defect and a concomitant severe soft tissue lesion.

Nodular type predominance of head and neck cutaneous malignant melanoma in Asian populations leads to poor outcome and low survival.

Cutaneous malignant melanomas of the head and neck (HNM) are proposed to have notable histological and clinical differences from those at other sites (other melanoma); however, HNMs among Asians have remained poorly understood. This study aimed to investigate the clinicopathological features and prognostic factors of HNM in Asians. Asian melanoma patients who underwent surgical treatment from January 2003 to December 2020 were retrospectively reviewed.

Microplastics in large marine animals stranded in the Republic of Korea.

Microplastics (MPs) are found in every ocean and are frequently ingested by marine animals.
