Checklist for the insect fauna of two East Sea Islands (Ulleungdo Is. and Dokdo Is.) in the Republic of Korea.

Background: Ulleungdo and Dokdo, located in the East Sea, are volcanic islands with high ecological value due to their unique biodiversity. Although research on the insect fauna on these two Islands has been conducted from the early 19 century to recent times, limitations exist due to several issues, including misidentifications and historical errors. This study addresses these issues by conducting a comprehensive insect survey from 2020 to 2023, re-identifying misidentified specimens and compiling references to create an updated and accurate checklist of insect species for Ulleungdo and Dokdo.

Leaves Alleviate Cognitive Dysfunction in Dextran Sulfate Sodium (DSS)-Induced Colitis Mice through Regulating JNK/TLR4 Signaling Pathway.

To evaluate the effect of PM on the antioxidant system, superoxide dismutase (SOD) contents, reduced glutathione (GSH) contents, and malondialdehyde (MDA) contents were measured in colon and brain tissues.

Insect fauna including unrecorded species in Ulleungdo, South Korea.

Background: Ulleungdo harbours a unique ecosystem owing to its isolation from the mainland alongside its maritime climate. The island, formed via volcanic activity, is the largest island in the East Sea of Korea and retains a primeval forest. The ecosystems are being destroyed owing to increasing human activity on the island.

Photochemical advanced oxidative process treatment effect on the pesticide residues reduction and quality changes in dried red peppers.

Pesticide residues in crops are widely monitored, and the residue reduction techniques at the post-harvest stage are important to maintain food safety. In dried crops, pesticide residues can be concentrated after dehydration, which increases concerns regarding residue risk. Therefore, the residue reduction effects of ultraviolet (UV), ozone, and photochemical advanced oxidative process (pAOP) were investigated for dried peppers at the post-harvest stage.

Allograft dysfunction and parenchymal necrosis associated with renal artery stenosis and perigraft hematoma after kidney transplantation.

Transplant renal artery stenosis (TRAS) is one cause of allograft dysfunction. TRAS causes parenchymal necrosis and graft insufficiency. Herein, we report the case of a 40-year-old female with end-stage renal disease due to immunoglobulin A nephropathy, who underwent kidney transplantation with her elder sister.

Pall. Improves -Induced Inflammatory Responses in Mouse Ear Edema Model and Suppresses Pro-Inflammatory Chemokine Production via MAPK and NF-κB Pathways in HaCaT Cells.

Acne, also known as acne vulgaris, is a common disorder of human skin involving the sebaceous gland and (). Although there are a number of treatments suggested for acne, many of them have limitations in their safety and have efficacy issues. Therefore, there is a high demand to develop safe and effective novel acne treatments.

Efficacy and Safety of Ultra-Low-Dose Valganciclovir Chemoprophylaxis for Cytomegalovirus Infection in High-Risk Kidney Transplantation Patients.

Introduction: Valganciclovir (VGCV) prophylaxis of 900 mg twice daily for 6 months is recommended to prevent cytomegalovirus (CMV) infection, which is a major cause of decreased graft and patient survival in kidney transplant recipients. However, recent studies have shown the efficacy of 900 mg once daily for 3 to 6 months. Maintaining VGCV compliance is difficult because of high drug costs and side effects, such as thrombocytopenia and leukopenia.

Effect of Volatile Organic Chemicals in Linné on Blood Pressure and Electroencephalogram.

This study identified the volatile organic compounds in the essential oils that are extracted from Linné ( Linné) and investigated the effects of the inhalation of these compounds. We detected a total of 41 volatile organic compounds, including 32 hydrocarbons, four acids, three alcohols, two ketones, and one aldehyde. In a sniffing test, seven types of volatile organic compounds were identified.

Placement of tunneled cuffed catheter for hemodialysis: Micropuncture kit versus Angiocath IV catheter.

Introduction: Tunneled cuffed catheters provide stable, instantaneous, long-term intravenous access for hemodialysis. Because catheterization is often performed in emergency situations, speed and accuracy are emphasized.

Methods: We retrospectively compared the Micropuncture kit with the standard 18-gauge Angiocath IV catheter for tunneled cuffed catheter insertion in the right jugular vein.

The purpose of this study was to compare clinical and radiographic outcomes of HTO between kissing lesion and non-kissing lesion groups.

Surgical Treatment of Sanders Type 2 Calcaneal Fractures Using a Sinus Tarsi Approach.

Background: Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet.

Bacillus aryabhattai SRB02 tolerates oxidative and nitrosative stress and promotes the growth of soybean by modulating the production of phytohormones.

Plant growth promoting rhizobacteria (PGPR) are diverse, naturally occurring bacteria that establish a close association with plant roots and promote the growth and immunity of plants. Established mechanisms involved in PGPR-mediated plant growth promotion include regulation of phytohormones, improved nutrient availability, and antagonistic effects on plant pathogens. In this study, we isolated a bacterium from the rhizospheric soil of a soybean field in Chungcheong buk-do, South Korea.

Vascular calcification on plain radiographs is related with the severity of lesions detected by coronary angiography in dialysis patients.

Coronary artery disease (CAD) is a primary cause of mortality and morbidity in dialysis patients. However, it is difficult to select the proper point for coronary angiographic procedure, because dialysis patients frequently do not display typical symptoms. Vascular calcification (VC) scores of artery or aorta on plain radiographs are associated with CAD events and may be predictive of CAD in dialysis patients.

Periodontal responses to augmented corticotomy with collagen membrane application during orthodontic buccal tipping in dogs.

This prospective randomized split-mouth study was performed to examine the effects of absorbable collagen membrane (ACM) application in augmented corticotomy using deproteinized bovine bone mineral (DBBM), during orthodontic buccal tipping movement in the dog. After buccal circumscribing corticotomy and DBBM grafting into the decorticated area, flaps were repositioned and sutured on control sides. ACM was overlaid and secured with membrane tacks, on test sides only, and the flaps were repositioned and sutured.
