Biotic elicitation is an important biotechnological strategy for triggering the accumulation of secondary metabolites in adventitious root cultures. These biotic elicitors can be obtained from safe, economically important strains of bacteria found in the rhizosphere and fermented foods. Here, we assayed the effects of filtered cultures of five nitrogen-fixing bacteria and four types of fermentation bacteria on mutant adventitious Panax ginseng root cultures induced in a previous study by colchicine treatment...

BACKGROUND: Aortic dissection (AD) is a life-threatening medical emergency caused by the abrupt destruction of the intimomedial layer of the aortic walls. Given that previous studies have reported the involvement of proinflammatory cytokine interleukin-6 in AD pathogenesis, we investigated the role of signal transduction and activator of transcription 3 signaling, a downstream pathway of interleukin-6 in macrophages in pathogenesis of AD. METHODS AND RESULTS: We characterized the pathological and molecular events triggered by aortic stress, which can lead to AD...

Transplant vasculopathy is one of the major causes of chronic rejection following solid organ transplantation. The pathogenic mechanisms of transplant vasculopathy are still poorly understood. Here we summarize current evidence suggesting that activation of the tunica adventitia may be involved in the pathogenesis of transplant vasculopathy. Adventitia is an early responder to various vascular injuries and plays an integral role in eliciting vascular inflammation and remodeling. Accumulation of macrophages in the adventitia promotes the development of vascular remodeling by releasing a variety of paracrine factors that have profound impacts on vascular mural cells...

Polycystic echinococcosis (PE) is caused by Echinococcus vogeli metacestodes (larval stage) in Neotropical countries. E. vogeli is trophically-transmitted between predators bush dogs (Speothos venaticus) and prey pacas (Cuniculus paca). In Brazil, reported PE cases are restricted to the Amazon biome. In this study, metacestodes from a paca hunted in Mato Grosso do Sul state (Cerrado biome) were identified morphological and histopathological techniques and further confirmed by molecular testing (sequencing of cytochrome C oxidase subunit I (cox1) gene) for the first time...

In plants, the formation of hypocotyl-derived adventitious roots (AR) is an important morphological acclimation to waterlogging stress; however, its genetic basis remains fragmentary. Here, through combined use of bulked segregant analysis-based whole genome sequencing, SNP haplotyping and fine genetic mapping, we identified a candidate gene for a major-effect QTL ARN6.1 that was responsible for waterlogging tolerance due to increased AR formation in the cucumber line Zaoer-N. Through multiple lines of evidence, we show that the CsARN6...

Though the composition of the three layers constituting the blood vessel wall varies among the different types of blood vessels, and some layers may even be missing in capillaries, certain basic components, and properties are shared by all blood vessels, though each histologically distinct layer contains a unique complement of extracellular components, growth factors and cytokines, and cell types as well. The structure and composition of vessel layers informs and is informed by the function of the particular blood vessel...

All fine root systems consist of individual fine roots. Individual roots have morphological, anatomical, and functional heterogeneity (heterorhizy). Heterorhizy plays crucial roles in plant ecosystems. However, in many species, the heterorhizy and fine root system architecture based on individual root units are unclear. This study investigated heterorhizy along the root system architecture of Vaccinium virgatum Ait (rabbiteye blueberry) softwood-cuttings (propagated from annual shoots in growing season) using protoxylem groups (PGs), a classification according to the number of protoxylem poles, as an indicator of individual root traits...

Chemical isolation and NMR-based structure elucidation revealed a novel keto-acidic sesquiterpenoid, termed zealexin A4 (ZA4). ZA4 is elicited by pathogens and herbivory, but attenuated by heightened levels of CO 2 . The identification of the labdane-related diterpenoids, termed kauralexins and acidic sesquiterpenoids, termed zealexins, demonstrated the existence of at least ten novel stress-inducible maize metabolites with diverse antimicrobial activity. Despite these advances, the identity of co-occurring and predictably related analytes remains largely unexplored...

Cannabinoids have considerable interest in the pharmaceutical industry. However, the production of medicines from hemp (Cannabis sativa L.) in most countries is restricted by law. Large-scale, field cultivation of hemp is difficult to control. Cannabinoid content in plants is variable and depends on multiple factors. Therefore, alternative methods of production have been investigated. The development of micropropagation techniques is a necessary step for genetic modification. Promising results have been obtained for certain narcotic genotypes...

The adventitia functions as a dynamic compartment for cell trafficking into and out of the artery wall, and communicates with medial and intimal cells. The resident cells in the tunica adventitia play an integral role in the regulation of vessel wall structure, repair, tone, and remodeling. Following injury to the vascular wall, adventitial fibroblasts are activated, which proliferate and differentiate into migratory myofibroblasts, and initiate inflammation through the secretion of soluble factors such as chemokines, cytokines, and adhesion molecules...

In alleged sexual assault investigations, the detection of male DNA on female intimate swabs can be established through Y-STR profiling. However, in cases where the defendant lives in the same dwelling as the complainant, the defendant may argue that his DNA was transferred through normal social contact, and dispute that intimate contact occurred. This study aimed to determine whether or not male DNA could be detected in samples collected from the vaginal cavity after everyday activities. A total of 300 samples from eight individuals were subjected to DNA quantification and Y-STR amplification...

Rice is a semiaquatic plant that is well adapted to partial flooding. Rice stems develop adventitious root (AR) primordia at each node that slowly mature but emerge only when the plant gets flooded leading to the formation of a whole new secondary root system upon flooding. AR growth is induced by ethylene that accumulates in submerged plant tissues due to its lowered diffusion rate in water. Here we report that the architecture of the secondary root system in flooded rice plants is not only controlled by altered gas diffusion but also by gravity and light...

Isotopic enrichment of 29Si and DNP-enhanced NMR spectroscopy are combined to determine the detailed surface structure of a silicated alumina catalyst. The significant sensitivity enhancement provided by DNP is vital to the acquisition of multinuclear and multidimensional experiments that provide information on the atomic-level structure of the species present at the surface. Isotopic enrichment not only facilitates spectral acquisition, particularly given the low (1.5 wt %) Si loading, but also enables spectra with higher resolution than those acquired using DNP to be obtained...

Perivascular adipose tissue (PVAT) surrounds most large blood vessels and plays an important role in vascular homeostasis. PVAT releases various chemokines and adipocytokines, functioning in an endocrine and paracrine manner to regulate vascular signaling and inflammation. Mounting evidence suggests that PVAT plays an important role in atherosclerosis and hypertension; however, the role of PVAT in non-atherosclerotic vascular diseases, including neointimal formation, aortic aneurysm, arterial stiffness and vasculitis, has received far less attention...
