Limnophilinae crane flies belonging to the genus Bergroth, 1891 of the Korean Peninsula were studied starting from 1937, but only one species (Alexander, 1923) has been recorded from North Korea so far. The genus was unknown from South Korea. Four species were found during our studies on the Peninsula, one of them from Jeju Island described as new, Podenas, Three species are recorded from both northern and southern parts of the Peninsula.

Urbanization is a leading factor effecting global biodiversity, driving rapid evolutionary processes in the local biota. Species that adapt and proliferate in city environments can become pests, with human activities facilitating their dispersal and excessive outbreaks. Here we present the first genome data of Plecia longiforceps, a lovebug pest in Eastern Asia with intensive aggregations recently occurring in the Seoul Metropolitan Area of Korea.

Article Synopsis
  • - The study investigates a new hybrid scaffold for bone regeneration made from gellan gum, hydroxyapatite, and polyethylene glycol, enhanced with a compound from ginseng (CK) for better cell adhesion and growth.
  • - Scanning electron microscopy (SEM) showed that the scaffold had an ideal pore distribution for cell growth, and the inclusion of CK improved its biological activity, as determined by MTT assay results.
  • - Overall, the research suggests that this engineered scaffold can better resemble natural bone tissue, which may lead to advancements in bone regeneration therapies.

The genus Kugelann (Goniaceritae: Bythinini) is the most species-rich genus of the subfamily Pselaphinae and is mainly distributed in the Palearctic region. Although previous studies have documented 14 species in the Korean Peninsula, the true diversity, ecology, and immature stages of the genus are still inadequately known. In this study, five new Korean species are described: , , , , and Illustrations of the habitus and other morphological details, and a distribution map are provided.

Hydrogel is a versatile material that can be manipulated to achieve the desired physicochemical properties, such as stiffness, pore size, and viscoelasticity. Traditionally, these properties have been controlled through parameters such as concentration and pH adjustments. In this study, we focused on exploring the potential of hydrolyzed silk fibroin (HSF) as a molecular weight-modulating agent to control the physicochemical properties of double-composite hydrogels.

Shape-memory polymers (SMPs) can be defined as a reversibly changing form through deformation and recovery by external stimuli. However, there remain application limitations of SMPs, such as complicated preparation processes and slow shape recovery. Here, we designed gelatin-based shape-memory scaffolds by a facile dipping method in tannic acid solution.

Latreille, 1809 is a large genus of short-palped crane flies with a worldwide distribution. Accounting for more than 60 percent of global species, 362 extant species occur in Asia. Prior to our study, crane flies on the Korean Peninsula (both the Democratic People's Republic of Korea and the Republic of Korea) had been studied for 90 years starting in 1930, but only three species had been recorded, with one of them being a misidentification.

This study shows tunable stress relaxing gellan gum (GG) hydrogel for enhanced cell growth and regenerative medicine. The molecular weight and physical crosslinking density of GG were tuned and characterized with physicochemical analysis and mechanical tests. The result showed that a decrease in the molecular weight of the GG correlated with a decline in the mechanical properties but faster stress relaxing character.

The cosmopolitan euaesthetine genus, Motschulsky, 1857, with about 90 Palaearctic species, was formerly known by a single species, Puthz, 2011, of which 2 specimens were collected in the southern part of the Korean Peninsula. In this paper, the knowledge of the Korean fauna is expanded to include six species, including four described here based on a rich material collected in recent years. A key to all six species of Korean , illustration of the habitus and diagnostic characters, and a distribution map are provided.

Although the high level of species diversity within the Pholcus phungiformes-group (Araneae: Pholcidae) in the Korean Peninsula has been recognized recently, taxonomic studies, including new species discovery, have not been conducted in western regions of South Korea. In this study, five additional species belonging to the Pholcus phungiformes-group discovered from Seoul and surrounding areas are described as new, viz., Pholcus seoulensis Lee Lee, sp.

Amorphization technology has been the subject of continuous attention in the pharmaceutical industry, as a means to enhance the solubility of poorly water-soluble drugs. Being in a high energy state, amorphous formulations generally display significantly increased apparent solubility as compared to their crystalline counterparts, which may allow them to generate a supersaturated state in the gastrointestinal tract and in turn, improve the bioavailability. Conventionally, hydrophilic polymers have been used as carriers, in which the amorphous drugs were dispersed and stabilized to form polymeric amorphous solid dispersions.
