Turning glucosinolate into allelopathic fate: investigating allyl isothiocyanate variability and nitrile formation in eco-friendly Brassica juncea from South Korea.

Leaf mustard (Brassica juncea L.) is explored for its biofumigant properties, derived from its secondary metabolites, particularly allyl isothiocyanate (AITC), produced during the enzymatic breakdown of glucosinolates like sinigrin. The research examines eight leaf mustard cultivars developed in Yeosu city, South Korea, focusing on their genetic characteristics, AITC concentration and nitriles formation rates from glucosinolates.

Leaf Mustard () Germplasm Resources Showed Diverse Characteristics in Agro-Morphological Traits and Glucosinolate Levels.

Leaf mustard, characterized by its purple/red/green leaves with a green/white midrib, is known for its thick, tender, and spicy leaves with a unique taste and flavor. There were only a few studies reported on leaf mustard for its morphological and biochemical traits from Korea. A total of 355 leaf mustard accessions stored at the GenBank of the National Agrobiodiversity Center were evaluated for 25 agro-morphological traits and seven intact glucosinolates (GSLs).

Biocompatibility and mineralization potential of new calcium silicate cements.

Background/purpose: As calcium silicate cements (CSCs) have been successfully used in various types of vital pulp therapy, many new CSC products have been developed. The aim of this study was to evaluate the biocompatibilities and mineralization potential of new CSC. The experimental materials were NeoMTA Plus and EndoSequence Root Repair Material-Fast Set Putty (ERRM-FS) which were compared to ProRoot MTA.

Distinctive cytokine profiles of stem cells from human exfoliated deciduous teeth and dental pulp stem cells.

Background/purpose: SHED and DPSC have stem cell regenerative potential, but comparative research on their cytokine profile is rare. This study aimed to investigate and compare cytokine profiles secreted from stem cells from human exfoliated deciduous teeth (SHED) and dental pulp stem cells (DPSCs).

Materials And Methods: SHED-conditioned medium (CM) and DPSC-CM were extracted using seven primary and permanent teeth each.

Chronological Change of Right Ventricle by Chronic Intermittent Hypoxia in Mice.

Study Objective: No studies have investigated sequential changes in the heart on magnetic resonance imaging (MRI), along with observation of functional lung phenotypes and genetics, over the duration of chronic intermittent hypoxia (CIH). We investigated chronological changes in heart and lung phenotypes after CIH using a mouse model to provide new insights into the pathophysiology of sleep apnea-induced cardiovascular disease.

Methods: C57BL/6J adult male mice were randomized to 4 or 8 weeks of CIH.

Synergistic mucus secretion by histamine and IL-4 through TMEM16A in airway epithelium.

Histamine is an important mediator of allergic reactions, and mucus hypersecretion is a major allergic symptom. However, the direct effect of histamine on mucus secretion from airway mucosal epithelia has not been clearly demonstrated. TMEM16A is a Ca-activated chloride channel, and it is closely related to fluid secretion in airway mucosal epithelia.

Newly developed method for mouse olfactory behavior tests using an automatic video tracking system.

Objective: The mouse is the most popular animal model in olfactory research. Behavior tests with odorants are essential for determining olfactory phenotype. To the best of our knowledge, the mouse olfactory behavior test has not been standardized, making the results vulnerable to inter-observer variation.

Characteristics of SiO2/Si3N4/SiO2 stacked-gate dielectrics obtained via atomic-layer deposition.

An interpoly-stacked dielectric film with a SiO2/Si3N4/SiO2/Si (ONO) structure was prepared via the atomic-layer deposition method. The multilayer structure of the ONO film with triple interfaces was investigated via medium-energy ion scattering (MEIS). A few defects in the interface layer of the ONO structure were detected.

Effect of herbal extract mixture on menopausal urinary incontinence in ovariectomized rats.

The decline of estrogen production after menopause is contributing factor to urinary incontinence (UI), and particularly stress urinary incontinence (SUI). We determined the preventive effects of herbal extract mixture (HEM) on UI in ovariectomized Sprague Dawley rats. Female 9-weeks old rats were ovariectomized and treated with HEM (2.
