Functional impacts of PtrMYB203 on phenylpropanoid pathway regulation and wood properties in hybrid poplar.

The phenylpropanoid pathway is vital for plant growth and development, producing lignin and flavonoids. This study investigates PtrMYB203, a homolog of MYB repressors of proanthocyanidin (PA) biosynthesis in Populus trichocarpa, as a transcriptional repressor in the phenylpropanoid pathway of hybrid poplar (Populus alba x P. glandulosa).

Tuberculosis and Nontuberculous Mycobacterial Infections in Patients with Spondyloarthritis: A Population-Based Study.

: Tuberculosis is caused by Mycobacterium tuberculosis (MTB), while nontuberculous mycobacteria (NTM) encompass a group of mycobacterial species that are distinct from the MTB complex and leprae. Spondyloarthritis (SpA) is a group of chronic inflammatory diseases with shared clinical characteristics and is treated with biological agents; however, their use may elevate the risk of MTB and NTM infections. This study aimed to compare the incidence and risk of MTB and NTM infections in patients with SpA, including ankylosing spondylitis (AS) and psoriatic arthritis (PsA), using a population-based approach.

Cancer risks in patients with ankylosing spondylitis and the effects of biologic agents: a population-based study.

Objective: The objective of this study was to conduct a population-based analysis of the malignancy risks of patients with AS.

Methods: A total of 1796 patients with AS and 7184 age- and sex-matched controls (1:4 ratio) were selected from the Korea National Health Insurance Service-National Sample Cohort database. Data of patients diagnosed with AS (code M45) according to the International Classification of Diseases (ICD) 10th edition, between 2002 and 2019, were reviewed.

Life expectancy and healthy life expectancy of Korean registered disabled by disability type in 2014-2018: Korea National Rehabilitation Center database.

Background: Conducting a distinct comparison between the life expectancy (LE) and healthy life expectancy (HALE) of people with disabilities (PWDs) and the general population is necessary due to the various environmental and health conditions they encounter. Therefore, this study aimed to develop the life table for PWDs and calculate those of LE and HALE based on sex, severity, and disability types among the registered Korean PWDs.

Methods: We used aggregated data of registered PWDs from the Korea National Rehabilitation Center database between 2014 and 2018.

Knockdown of Confers Drought Resistance and Promotes Lateral Shoot Growth in Hybrid Poplar ( × var. ).

Plants have evolved defense mechanisms to overcome unfavorable climatic conditions. The growth and development of plants are regulated in response to environmental stress. In this study, we investigated the molecular and physiological characteristics of a novel gene in hybrid poplar ( × var.

CRISPR-Knockout of Gene Improves Saccharification Efficiency by Reducing Lignin Content in Hybrid Poplar.

Caffeoyl shikimate esterase (CSE) has been shown to play an important role in lignin biosynthesis in plants and is, therefore, a promising target for generating improved lignocellulosic biomass crops for sustainable biofuel production. spp. has two genes ( and ) and, thus, the hybrid poplar ( × ) investigated in this study has four genes.

Quantitative and Qualitative Differences of Action Verbal Fluency between Young and Older Adults.

Introduction: Action verbal fluency (AVF) task, a word fluency test, involves language and executive function and is known to be sensitive to fronto-striatal degeneration. However, the ability may also decrease qualitatively as well as quantitatively in normal aging. The objective of this study is to investigate the age-related quantitative and qualitative differences in AVF of Korean adults.

Evaluation of aromatic hydrocarbon decomposition catalyzed by the dioxygenase system and substitution of ferredoxin and ferredoxin reductase.

In this study, the catalytic activity and kinetic characteristics of the aromatic hydrocarbon dioxygenase system and the possibility of substituting its ferredoxin and ferredoxin reductase components were evaluated. The genes encoding toluene dioxygenase and toluene dihydrodiol dehydrogenase were cloned from Pseudomonas putida F1, and the corresponding enzymes were overexpressed and purified to homogeneity. Oxidative hydroxylation of toluene to cis-toluene dihydrodiol was catalyzed by toluene dioxygenase, and its subsequent dehydrogenation to 3-methylcatechol was catalyzed by toluene dihydrodiol dehydrogenase.
