Effect of Sugar Solution Specific Gravity on Cyst Extraction and Egg Viability in Two Cyst Nematodes Using Centrifugal Floatation.

Cyst nematodes, some of the most important plant-parasitic nematodes globally, cause major damage to Chinese cabbage and soybean plants in Korea. Cysts are commonly used for cyst nematode bioassays because many eggs are included inside cyst. Traditionally, cysts are extracted from the soil using the paper strip method or the centrifugal flotation method (CFM) combined with sieving.

Clover Cyst Nematode Dominates and Causes Damage in Kimchi-Cabbage Fields in Korea.

Cyst nematodes are among the major plant-parasitic nematodes worldwide, and they cause significant damage to Brassicaceae crops, including Kimchi-cabbage, in Korea. To survey the incidence of cyst nematodes in Kimchi-cabbage fields, 469 soil samples were collected from the main producing areas between 2018 and 2021. Only cyst nematodes belonging to the genus Heterodera were investigated, and the overall nematode incidence was found to be 40%.

Microbial allies recruited by Bacillus subtilis JCK-1398 to defend pine trees against pinewood nematode.

Pine wilt disease (PWD) is a devastating disease caused by the pinewood nematode (Bursaphelenchus xylophilus). Its substantial ecological disruption harms global forestry and poses serious economic challenges. Although previous research has demonstrated that Bacillus subtilis JCK-1398 has the potential to induce systemic resistance in pine trees, the ecological mechanisms underlying its biocontrol efficacy remain underexplored.

Senolytic Targeting of Anti-Apoptotic Bcl Family Increases Cell Death in UV-Irradiated Senescent Melanocytes: Search for Senolytics.

Senescent melanocytes have been suggested to play a role in the development of ageing-associated pigmentary changes and skin ageing. Here, we assessed the senolytic capacity of recognised senolytic chemicals and natural compounds in UV-irradiated senescent melanocytes. Among the tested agents, only ABT-737 and ABT-263 showed a significant reduction in the number of SA-β-Gal-positive senescent melanocytes and in the expressions of p16 and p21.

Biocontrol potential of natamycin-producing Streptomyces lydicus JCK-6019 against soil-borne fungal diseases of cucumber and characterization of its biocontrol mechanism.

Background: Fusarium oxysporum f. sp. cucumerinum and Rhizoctonia solani AG-4 are the two most important fungal pathogens causing soil-borne fungal diseases of cucumber; they are difficult to control and cause serious economic losses.

Distribution and impact of p16 senescent cells in elderly tissues: a focus on senescent immune cell and epithelial dysfunction.

Cellular senescence, recognized as a key hallmark of aging, leads to the accumulation of senescent cells in various tissues over time. While the detrimental effects of these cells on age-related pathological conditions are well-documented, there is still limited information about how senescent cells are distributed in normal tissues of both young and aged organs. Our research indicates that fully senescent p16 cells are rarely identified in the parenchyma of organic tissues and in the stromal cells crucial for structural maintenance, such as fibroblasts and smooth muscle cells.

Eco-friendly biocontrol of pine wilt disease: Enhancing tree defense with Bacillus subtilis JCK-1398 for sustainable forest management.

Pine wilt disease (PWD), caused by pinewood nematodes (Bursaphelenchus xylophilus), poses a significant threat to forestry worldwide. This study introduces a novel biocontrol strategy using Bacillus subtilis JCK-1398, which was selected and identified for its resistance-induction potential after extensive screening of microbial strains from pine tissues. The bacterium was found to biostimulate resistance in Pinus densiflora.

Undibacterium cyanobacteriorum sp. nov., an auxin-producing bacterium isolated from fresh water during cyanobacterial bloom period.

A novel Gram-negative, white-pigmented, and auxin-producing strain, 20NA77.5, was isolated from fresh water during cyanobacterial bloom period. Pairwise comparison of the 16S rRNA gene sequences showed that strain 20NA77.

Biocontrol of head blight in rice using JCK-7158.

head blight (FHB) is a destructive disease caused by several species of , such as and . FHB affects cereal crops, including wheat, barley, and rice, worldwide. -infected kernels not only cause reduced yields but also cause quality loss by producing mycotoxins, such as trichothecenes and zearalenone, which are toxic to animals and humans.

Successful repigmentation of hypopigmented scars with micropunch grafting with a skin-seeding technique.

Hypopigmented scars are challenging to treat, and the focus for successful treatment is to cause pigment cells to produce more melanin. In this study, we evaluated the repigmentation effects of 0.4 mm motorized-micropunch grafting with skin-seeding for hypopigmented scars.

Comparative study on the age-related incidence of seborrheic keratosis and verruca plana in patients with verruca plana-like lesions.

Seborrheic keratosis (SK) is a common skin disease in the elderly. However, in cases where SK presenting as multiple skin-colored or clustered lesions can be easily misdiagnosed as verruca plana (VP), especially in the young population. This retrospective study investigated the prevalence of SK and VP in the lesions that appear clinically similar to VP according to age.

Transcriptomic Insights into Abies koreana Drought Tolerance Conferred by Aureobasidium pullulans AK10.

The conservation of the endangered Korean fir, Abies koreana, is of critical ecological importance. In our previous study, a yeast-like fungus identified as Aureobasidium pullulans AK10, was isolated and shown to enhance drought tolerance in A. koreana seedlings.

Targeting the dermis for melasma maintenance treatment.

Melasma relapse is almost common after discontinuation of conventional treatment. Recent studies suggesting that photoaging dermis is the main pathomechanism of melasma, emphasize the dermal targeting therapy. We investigated maintenance effect of microneedling radiofrequency (RF) for melasma treatment.

Multiple Eruptive Epithelioid Hemangiomas on the Right Upper Extremity in an Asian Man.

Epithelioid hemangioma is a rare benign vascular neoplasm. Recently, the term "multiple eruptive epithelioid hemangioma" has been proposed for epithelioid hemangioma with distinct features. It is different from usual epithelioid hemangioma because of the multifocal distributions in various body regions with an eruptive onset.

Case Report: Erythema Multiforme Induced by Lithium Contact.

Erythema multiforme (EM) is an acute, self-limited mucocutaneous disease with diverse triggering factors, and the recurrences are quite common. A 24-year old male presented with multiple erythematous, itchy papules and plaques on multiple sites. He has worked in a lithium battery factory and experienced the chemical burn 2 weeks ago.

Pulsed-dye laser as an effective treatment for recalcitrant granulomatous rosacea and a potential regulator of CXCL9 expression.

Granulomatous rosacea (GR) is a rare and distinct variant of rosacea. We report three cases of recalcitrant GR successfully treated with pulsed-dye laser (PDL) and provide experimental evidence supporting its potential as a treatment option. PDL treatment demonstrated remarkable efficacy in the three clinical cases, despite their resistance to conventional therapies.

Mid-old cells are a potential target for anti-aging interventions in the elderly.

The biological process of aging is thought to result in part from accumulation of senescent cells in organs. However, the present study identified a subset of fibroblasts and smooth muscle cells which are the major constituents of organ stroma neither proliferative nor senescent in tissues of the elderly, which we termed "mid-old status" cells. Upregulation of pro-inflammatory genes (IL1B and SAA1) and downregulation of anti-inflammatory genes (SLIT2 and CXCL12) were detected in mid-old cells.
