The role of E-leadership in ICT utilization: a project management perspective.

Unlabelled: Covid 19 presents a great challenge and opportunity for remote working, highlighting the need for electronically-mediated leadership in team tasks and performance. What is the role of leadership in improving utilization of information communication technologies (ICTs) in teamwork? Framed within the e-leadership and project management literature and employing a longitudinal field observation method over 8 months that involves 52 subjects and 172 observations, this study finds that (1) first, strong leaders employ a consistent and high-level use of ICTs throughout the whole process of group work, especially at the planning and closing stages of a project. (2) Second, strong leaders alternate the use of various ICTs to match specific tasks at different phases of the project.

Interactions between Polygenic Risk Scores, Dietary Pattern, and Menarche Age with the Obesity Risk in a Large Hospital-Based Cohort.

Obese Asians are more susceptible to metabolic diseases than obese Caucasians of the same body mass index (BMI). We hypothesized that the genetic variants associated with obesity risk interact with the lifestyles of middle-aged and elderly adults, possibly allowing the development of personalized interventions based on genotype. We aimed to examine this hypothesis in a large city hospital-based cohort in Korea.

A Traditional Korean Diet Alters the Expression of Circulating MicroRNAs Linked to Diabetes Mellitus in a Pilot Trial.

The traditional Korean diet (K-diet) is considered to be healthy and circulating microRNAs (miRs) have been proposed as useful markers or targets in diet therapy. We, therefore, investigated the metabolic influence of the K-diet by evaluating the expression of plasma and salivary miRs. Ten women aged 50 to 60 years were divided into either a K-diet or control diet (a Westernized Korean diet) group.

Luteolin improves hypercholesterolemia and glucose intolerance through LXRα-dependent pathway in diet-induced obese mice.

Luteolin, a naturally derived flavonoid, exerts beneficial effects such as antitumor, antioxidant, and anti-inflammatory effects. However, the molecular mechanism underlying the effect of luteolin in hypercholesterolemia remains unclear. In this study, we demonstrated that luteolin upregulated the expression of liver X receptor (LXR) α, ATP-binding cassette transporter G1 (ABCG1), and scavenger receptor class B member 1 (SRB1), which play a major role in cholesterol efflux, in HepG2 hepatocytes.

Physical and Functional Interaction between 5-HT Receptor and Nova-1.

5-HT receptor (5-HTR) is implicated in cognitive dysfunction, mood disorder, psychosis, and eating disorders. However, despite its significant role in regulating the brain functions, regulation of 5-HTR at the molecular level is poorly understood. Here, using yeast two-hybrid assay, we found that human 5-HTR directly binds to neuro-oncological ventral antigen 1 (Nova-1), a brain-enriched splicing regulator.

Epigenetic modification by dietary factors: Implications in metabolic syndrome.

Dietary factors play a role in normal biological processes and are involved in the regulation of pathological progression over a lifetime. Evidence has emerged indicating that dietary factor-dependent epigenetic modifications can significantly affect genome stability and the expression of mRNA and proteins, which are involved in metabolic dysfunction. Since metabolic syndrome is a progressive phenotype characterized by insulin resistance, obesity, hypertension, dyslipidemia, or type 2 diabetes, gene-diet interactions are important processes involved in the initiation of particular symptoms of metabolic syndrome and their progression.

ABA-HYPERSENSITIVE BTB/POZ PROTEIN 1 functions as a negative regulator in ABA-mediated inhibition of germination in Arabidopsis.

To elucidate the contribution of CRL3-ABA-mediated responses, we attempted to find CRL3 substrate receptors involved in ABA signaling. One gene named ABA-HYPERSENSITIVE BTB/POZ PROTEIN 1 (AHT1) was upregulated more than 2.5 times by ABA, and its coding region possessed a BTB/POZ domain, which is the common feature of CRL3 substrate receptors.

Reduced IRF7 response to rhinovirus unrelated with DNA methylation in peripheral mononuclear cells of adult asthmatics.

Background: Human rhinoviruses are the major cause of asthma exacerbation in both children and adults. Recently, impaired antiviral interferon (IFN) response in asthmatics has been indicated as a primary reason of the susceptibility to respiratory virus, but the mechanism of defective IFN production is little understood to date. The expression of IFN regulatory factor 7 (IRF7), a transcriptional factor for virus-induced type I IFN production is known to be regulated epigenetically by DNA methylation.

Characterization of a Novel DWD protein that participates in heat stress response in Arabidopsis.

Cullin4-RING ubiquitin ligase (CRL4) is a family of multi-subunit E3 ligases. To investigate the possible involvement of CRL4 in heat stress response, we screened T-DNA insertion mutants of putative CRL4 substrate receptors that exhibited altered patterns in response to heat stress. One of the mutants exhibited heat stress tolerance and was named heat stress tolerant DWD1 (htd1).

DWD HYPERSENSITIVE TO UV-B 1 is negatively involved in UV-B mediated cellular responses in Arabidopsis.

Among T-DNA insertion mutants of various cullin4-RING ubiquitin E3 ligase (CRL4) substrate receptors, one mutant that exhibits enhanced sensitivity in response to ultraviolet-B (UV-B) illumination has been isolated and its corresponding gene has been named DWD HYPERSENSITIVE TO UV-B 1 (DHU1) in Arabidopsis. dhu1 lines showed much shorter hypocotyls than those in wild type under low doses of UV-B. Other light did not alter hypocotyl growth patterns in dhu1, indicating the hypersensitivity of dhu1 is restricted to UV-B.
