IbNAC1 is known to activate the defense system by reprogramming a genetic network against herbivory in sweet potato. This regulatory activity elevates plant defense potential but relatively weakens plants by IbNAC1-mediated JA response. The mechanism controlling IbNAC1 expression to balance plant vitality and survival remains unclear. In this study, a wound-responsive G-box cis-element in the IbNAC1 promoter from -1484 to -1479 bp was identified. From a screen of wound-activated transcriptomic data, one transcriptional activator, IbbHLH3, and one repressor, IbbHLH4, were selected that bind to and activate or repress, respectively, the G-box motif in the IbNAC1 promoter to modulate the IbNAC1-mediated response...

Glucocorticoids (GCs) play a vital role in the regulation of blood pressure by their permissive effects in potentiating vasoactive responses to catecholamines through glucocorticoid receptors. GCs achieve this function by controlling vascular smooth muscle tone. Clinically, low to moderate doses of GCs are generally used in the treatment of septic shock in recent years. GCs are now known to have both genomic and non-genomic effects. While genomic effects of GCs were well studied, few non-genomic effects were reported, much less the non-genomic mechanisms...

As animals move through their environments they are subjected to an endless barrage of sensory signals. Of these, some will be of utmost importance, such as the tell-tale aroma of a potential mate, the distinctive appearance of a vital food source or the unmistakable sound of an approaching predator. Others will be less important. Indeed some will not be important at all. There are, for instance, wide realms of the sensory world that remain entirely undetected, simply because an animal lacks the physiological capacity to detect and analyse the signals that characterise this realm...

Improving patient safety is vital for all hospitals due to increasing public reporting and pay-for-performance reimbursement. Venous thromboembolism (VTE) remains a leading cause of preventable mortality accounting for 5 per cent of inpatient deaths. The purpose of this study was to outline the process of implementing standard VTE prophylactic order sets in a 600-bed academic safety net hospital and assess the resulting change in patient outcomes. Outcomes were assessed by comparing the rate that eligible inpatients receive VTE prophylaxis and the rate of preventable VTE's compared with total VTE's...

Consensus is lacking for ideal management of mild traumatic brain injury (mTBI) with intracranial hemorrhage (ICH). Patients are often monitored in the intensive care unit (ICU) without additional interventions. We sought to identify admission variables associated with a favorable outcome (ICU admission for 24 hours, no neurosurgical interventions, no complications or mortality) to divert these patients to a non-ICU setting in the future. We reviewed all patients with mTBI [Glasgow Coma Scale (GCS) = 13-15] and concomitant ICH between July 1, 2012, and June 30, 2015...

Elderly trauma patients may be at increased risk for underassessment and inadequate pain control in the emergency department (ED). We sought to characterize risk factors for oligoanalgesia in the ED in elderly trauma patients and determine whether it impacts outcomes in elderly trauma patients. We included elderly patients (age ≥55 years) with Glasgow Coma Scale scores 13 to 15 and Injury Severity Score (ISS) ≥9 admitted through the ED at a Level I trauma center. Patient characteristics and outcomes were compared between those who reported pain and received analgesics medication in the ED (MED) and those who did not (NO MED)...

INTRODUCTION: This paper investigates personality traits as potential factors for success in an astronaut selection by comparing personality profiles of unsuccessful and successful astronaut candidates in different phases of the ESA selection procedure. It is further addressed whether personality traits could predict an overall assessment rating at the end of the selection. METHODS: In 2008/2009, ESA performed an astronaut selection with 902 candidates who were either psychologically recommended for mission training (N = 46) or failed in basic aptitude (N = 710) or Assessment Center and interview testing (N = 146)...

OBJECTIVE: We examined the mediational role of symptoms of anxiety in accounting for the association of discrimination and chronic health conditions among African-American women. METHODS: Participants were 646 African-American women who completed self-report measures of perceived racial discrimination, symptoms of anxiety, and diagnosed chronic health problems. RESULTS: We examined the mediation hypothesis using a path analytic procedure. Mediational analyses indicated that, above and beyond symptoms of depression, age, and education status, anxiety symptoms were associated with both racial discrimination (β = ...

In many parts of the United States, mosquitoes were previously nuisance pests. However, they now represent a potential threat in the spread of viral diseases. The Aedes aegypti, Aedes albopictus, and Culex species mosquitoes are endemic to the United States and together may transmit a variety of viral diseases of growing concern including West Nile Virus, chikungunya, dengue fever, and Zika virus. The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) recommend N,N-diethyl-meta-toluamide (DEET) as a first-line mosquito repellent, but for patients refusing DEET or other conventional repellents, guidance is limited to any EPA-registered product...

Metformin was demonstrated to have effects on breast cancer, and microRNA-27a (miR-27a) is a prognostic marker for breast cancer progression and patient survival. AMPKα2 was found to be a suppressor in breast cancer MCF-7 cells. Therefore, the present study aimed to explain this phenomenon in regards to the relationship between microRNAs (miRNAs) and their target genes and to predict how AMPKα2 may be a downstream target gene of miR-27a, thus exploring the new mechanism of metformin in the treatment of breast cancer regarding miRNAs...

Metastasis of breast cancer is the vital step for malignant progression. During such a process, hematogenous metastasis is an indispensable approach for the dissemination of cancer cells. A platelet, contributes to hypercoagulable state, and is also identified the crucial factor in the coagulation system for supporting metastasis. Therefore, the relationship of a platelet and a tumor cell plays a critical role in tumor cell metastasis. Consequently, inhibiting tumor cell‑induced platelet aggregation (TCIPA) is recongnized as a crucial target on suppression of tumor metastasis such as aspirin (ASA)...

Understanding and assessing diabetic metabolism is vital for monitoring disease progression and improving treatment of patients. In vivo assessments, using MRI and MRS, provide non-invasive and accurate measurements, and the development of hyperpolarized (13) C spectroscopy in particular has been demonstrated to provide valuable metabolic data in real time. Until now, studies have focussed on individual organs. However, diabetes is a systemic disease affecting multiple tissues in the body. Therefore, we have developed a technique to simultaneously measure metabolism in both the heart and liver during a single acquisition...

In 2003, Japan's Ministry of Health, Labour and Welfare halted the neuroblastoma (NB) mass screening program, running since 1985. This study aimed to examine whether NB incidence and mortality changed before and after the program halted. This is a descriptive population-based study. We used data from the Monitoring of Cancer Incidence in Japan (MCIJ) project, Vital Statistics of Japan, and Japanese CANcer Survival Information for Society (J-CANSIS). Incidence rate, cumulative incidence rate, mortality rate, cumulative mortality rate, and relative 5-year survival for NB were calculated...

BACKGROUND: There is strong evidence to indicate that regular moderate intensity physical activity is associated with health benefits. Furthermore, sedentary behavior has been related with an increased risk for all-cause mortality. The accurate measurement of physical activity and sedentary behavior is therefore vital to evaluate their health impact and provide evidence for the development of public health recommendations. This paper describes the methodology used for assessing physical activity and sedentary behavior in the Belgian population in the context of the Belgian National Food Consumption Survey 2014 (BNFCS2014)...
