The presence of clonal isotype switch after autologous stem cell transplantation as a prognostic biomarker for long-term survival in patients with multiple myeloma.

Clonal isotype switch (CIS) in multiple myeloma (MM) refers to the emergence of new immunoglobulin bands distinct from those present at diagnosis. CIS often appears after high-dose chemotherapy and autologous stem cell transplantation (ASCT), reflecting post-transplant immune recovery. However, its prognostic significance remains unclear.

New machine learning-based automatic high-throughput video tracking system for assessing water toxicity using Daphnia Magna locomotory responses.

Daphnia magna is an important organism in ecotoxicity studies because it is sensitive to toxic substances and easy to culture in laboratory conditions. Its locomotory responses as a biomarker are highlighted in many studies. Over the last several years, multiple high-throughput video tracking systems have been developed to measure the locomotory responses of Daphnia magna.

Insulin resistance mediates high-fat diet-induced pulmonary fibrosis and airway hyperresponsiveness through the TGF-β1 pathway.

Prior studies have reported the presence of lung fibrosis and enhanced airway hyperresponsiveness (AHR) in mice with high-fat-diet (HFD)-induced obesity. This study evaluated the role of TGF-β1 in HFD-induced AHR and lung fibrosis in a murine model. We generated HFD-induced obesity mice and performed glucose and insulin tolerance tests.

Potential of serum soluble CD93 as a biomarker for asthma in an ovalbumin-induced asthma murine model.

Background: CD93 is a membrane-associated glycoprotein, which can be released in a soluble form (sCD93) into the serum. CD93 has received renewed attention as a candidate biomarker of inflammation in various inflammatory and immune-mediated diseases, including asthma.

Objective: We aimed to evaluate the effects of airway inflammation on CD93 levels in murine models.

Identification of Major Flavone C-Glycosides and Their Optimized Extraction from Cymbidium kanran Using Deep Eutectic Solvents.

, an orchid exclusively distributed in Northeast Asia, has been highly valued as a decorative plant and traditional herbal medicine. Here, extracts were prepared in 70% aqueous methanol using ultrasound-assisted extraction (UAE) and subjected to liquid chromatography-photodiode array detection and ultra-high performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry analysis, which were used for quantitative and qualitative analysis, respectively. It was found that the extracts were rich in flavone -glycosides including vicenin-2, vicenin-3, schaftoside, vitexin, and isovitexin.

Characterization of a Major Allergen from Mongolian Oak, Quercus mongolica, a Dominant Species of Oak in Korea.

Background: Oaks are the most common trees in Korean forests, and Mongolian oak, Quercus mongolica, is the dominant species. However, no allergen has been characterized from Mongolian oak. In this study, we tried to characterize a major allergen from Mongolian oak.

The complete chloroplast genome sequence of the Japanese Camellia ( L.).

The complete chloroplast genome sequence of valuable ornamental tree, L. (Theaceae), was determined. The genome size was 156,971 bp in length, containing a pair of 25,798 bp inverted repeat (IR) regions, which were separated by small and large single copy regions (SSC and LSC) of 18,394 and 86,673 bp, respectively.

Improvement Characteristics of Bio-active Materials Coated Fabric on Rat Muscular Mitochondria.

This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified. By wearing the BMCF, the oxidative respiration significantly increased when using the 30% materials coated fabric.

Different methylation profiles between intestinal and diffuse sporadic gastric carcinogenesis.

Objective: Gastric cancer (GC) is histologically classified into intestinal type and diffuse type, and diffuse type cancer can be further subdivided into poorly differentiated carcinoma (PDC) and signet ring cell carcinoma (SRCC). Recent evidence suggests that early SRCC is an initial, differentiated form of diffuse GC that may evolve into PDC. This study aimed at identifying the molecular features of epigenetic methylation changes in histologic differentiation status of GC.

TP53BP2 locus is associated with gastric cancer susceptibility.

We investigated the association of the TP53BP2 locus with gastric cancer susceptibility in a Korean population. We assayed 9 single nucleotide polymorphisms (SNP) in an 82.5 kb region that included the TP53BP2 locus in 233 male gastric cancer patients and 390 unaffected healthy male controls.
