Characterization of Diploid Wheat Flour and its Possible Practical Use.

The application of flour is determined by the composition of its starch and storage proteins. Previously isolated diploid wheat is known to be amylose-free and possesses the same amylopectin structure as the wild-type. To reveal its characteristics, starch, protein, lipid, fiber, gluten, and allergen contents and rheological properties were analyzed and compared to its parental wild-type diploid wheat and commercially available hexaploid wheats.

Cytoplasm of the Wild Species Reduces Gene Expression in Early Growth of Cultivated Wheat: Prospects for Using Alloplasmic Lines to Breed Varieties Adapted to Global Warming.

In a warm winter due to climate warming, it is necessary to suppress early flowering of autumn-sown wheat plants. Here, we propose the use of cytoplasmic genome effects for this purpose. Alloplasmic lines, or cytoplasmic substitution lines, of bread wheat () have cytoplasm from a related wild species through recurrent backcrossing and exhibit altered characteristics compared with the euplasmic lines from which they are derived.

A novel method for noninvasive bioelectric measurement utilizing conductivity of seawater.

A novel method of noninvasive bioelectric measurement that utilizes the conductivity of seawater covering a person's whole body is proposed. Concretely, a conductor used as a common electrode is sunk into the seawater, and four special bioelectrodes isolated from the seawater are attached at measurement points on the body. Bioelectric signals generated between the common electrode and special bioelectrodes are then measured.

-Adrenergic Receptor Agonist Prevents Diastolic Dysfunction in an Angiotensin II-Induced Cardiomyopathy Mouse Model.

β3-Adrenergic receptor expression is enhanced in the failing heart, but its functional effects are unclear. We tested the hypothesis that a 3-agonist improves left ventricular (LV) performance in heart failure. We examined the chronic effects of a 3-agonist in the angiotensin II (Ang II)-induced cardiomyopathy mouse model.

Effect of Gonadectomy and Angiotensin II Receptor Blockade in a Mouse Model of Isoproterenol-induced Cardiac Diastolic Dysfunction.

Background: Although heart failure (HF) with preserved ejection fraction (HFpEF) is more common in postmenopausal women than in men, the effect of sex hormones on cardiac diastolic function remains unclear. We examined the effect of gonadectomy with or without the angiotensin receptor blocker olmesartan (Olm) in an isoproterenol (ISO) -induced mouse model of left ventricular hypertrophy (LVH) and cardiac diastolic dysfunction.

Methods: ISO or ISO with Olm were administered for 28 days in sham-operated male and female, castrated (CAS), and ovariectomized (OVX) mice.

Introgression of chromosomal segments conferring early heading date from wheat diploid progenitor, Aegilops tauschii Coss., into Japanese elite wheat cultivars.

The breeding of agriculturally useful genes from wild crop relatives must take into account recent and future climate change. In Japan, the development of early heading wheat cultivars without the use of any major gene controlling the heading date is desired to avoid overlap of the harvesting time before the rainy season. Here, we backcrossed two early heading lines of a synthetic hexaploid wheat, derived from a crossing between durum wheat and the wild wheat progenitor Aegilops tauschii, with four Japanese elite cultivars to develop early heading lines of bread wheat.

Specialty-Related Differences in the Acute-Phase Treatment and Prognosis in Patients With Acute Heart Failure - Insights From REALITY-AHF.

Background: The aim of this study was to assess specialty-related differences in the treatment for patients with acute heart failure (AHF) in the acute phase and subsequent prognostic differences.

Methods and results: We analyzed hospitalizations for AHF in REALITY-AHF, a multicenter prospective registry focused on very early presentation and treatment in patients with AHF. All patients were classified according to the medical specialty of the physicians responsible for contributed most to decisions regarding the initial diagnosis and treatment after the emergency department (ED) arrival.

Extracellular volume fraction assessed using cardiovascular magnetic resonance can predict improvement in left ventricular ejection fraction in patients with dilated cardiomyopathy.

T1 mapping using cardiac magnetic resonance (CMR) is useful for myocardial assessment. However, its prognostic value is not well defined. The aim of this study was to determine whether T1 mapping with CMR can predict reverse cardiac remodeling in patients with non-ischemic dilated cardiomyopathy (NIDCM).

Identification of a Point Mutation in the Granule-bound Starch Synthase I Gene () in a Diploid Wheat Mutant and Design of Molecular Markers for Backcrossing.

In cereals, granule-bound starch synthase I (GBSSI)-deficient mutants accumulate glutinous (amylose-free) starch in their storage tissues. The amylose-free starch produced by () mutants of hexaploid bread wheat ( L.) is used in cakes and breads.

An early-flowering einkorn wheat mutant with deletions of PHYTOCLOCK 1/LUX ARRHYTHMO and VERNALIZATION 2 exhibits a high level of VERNALIZATION 1 expression induced by vernalization.

Using heavy-ion beam mutagenesis of Triticum monococcum strain KU104-1, we identified a mutant that shows extra early-flowering; it was named extra early-flowering 3 (exe3). Here, we carried out expression analyses of clock-related genes, clock downstream genes and photoperiod pathway genes, and found that the clock component gene PHYTOCLOCK 1/LUX ARRHYTHMO (PCL1/LUX) was not expressed in exe3 mutant plants. A PCR analysis of DNA markers indicated that the exe3 mutant had a deletion of wheat PCL1/LUX (WPCL1), and that the WPCL1 deletion was correlated with the mutant phenotype in the segregation line.

Direct interaction between VRN1 protein and the promoter region of the wheat FT gene.

The wheat florigen gene Wheat FLOWERING LOCUS T (WFT, which is identical to VRN3) is an integrator of the vernalization, photoperiod and autonomous pathways in wheat flowering. Many studies have indicated that VERNALIZATION 1 (VRN1) directly or indirectly up-regulates WFT expression in leaves. VRN1 encodes an APETALA1/FRUITFULL-like MADS box transcription factor that is up-regulated by vernalization and aging, leading to promotion of flowering.

Trends and predictors of non-cardiovascular death in patients hospitalized for acute heart failure.

Background: Little information is available on non-cardiovascular (CV) death in acute heart failure (AHF) patients. The present study determined the incidence, time course, and factors associated with long-term non-CV death in AHF patients in a real-world setting.

Methods: The ATTEND registry, a nationwide, prospective observational multicenter cohort study, included 4842 consecutive patients hospitalized for AHF.

Chronic obstructive pulmonary disease and β-blocker treatment in Asian patients with heart failure.

Aims: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are increasingly frequent in Asia and commonly coexist in patients. However, the prevalence of COPD among Asian patients with HF and its impact on HF treatment are unclear.

Methods And Results: We compared clinical characteristics and treatment approaches between patients with or without a history of COPD, before and after 1:2 propensity matching (for age, sex, geographical region, income level, and ethnic group) in 5232 prospectively recruited patients with HF and reduced ejection fraction (HFrEF, <40%) from 11 Asian regions (Northeast Asia: South Korea, Japan, Taiwan, Hong Kong, and China; South Asia: India; Southeast Asia: Thailand, Malaysia, Philippines, Indonesia, and Singapore).

Time-to-Furosemide Treatment and Mortality in Patients Hospitalized With Acute Heart Failure.

Background: Acute heart failure (AHF) is a life-threatening disease requiring urgent treatment, including a recommendation for immediate initiation of loop diuretics.

Objectives: The authors prospectively evaluated the association between time-to-diuretic treatment and clinical outcome.

Methods: REALITY-AHF (Registry Focused on Very Early Presentation and Treatment in Emergency Department of Acute Heart Failure) was a prospective, multicenter, observational cohort study that primarily aimed to assess the association between time to loop diuretic treatment and clinical outcome in patients with AHF admitted through the emergency department (ED).

Loss-of-Function Mutations in Three Homoeologous PHYTOCLOCK 1 Genes in Common Wheat Are Associated with the Extra-Early Flowering Phenotype.

Triticum aestivum L. cv 'Chogokuwase' is an extra-early flowering common wheat cultivar that is insensitive to photoperiod conferred by the photoperiod insensitive alleles at the Photoperiod-B1 (Ppd-B1) and Ppd-D1loci, and does not require vernalization for flowering. This reduced vernalization requirement is likely due to the spring habitat allele Vrn-D1 at the VERNALIZATION-D1 locus.

Superiority of the extracellular volume fraction over the myocardial T1 value for the assessment of myocardial fibrosis in patients with non-ischemic cardiomyopathy.

Purpose: This study aimed to assess the efficacies of the myocardial T1 value and the extracellular volume fraction (ECV) for determining the severity of myocardial fibrosis in patients with non-ischemic cardiomyopathy.

Materials And Methods: Myocardial fibrosis is considered the most important indicator of cardiac damage associated with non-ischemic cardiomyopathy. Recently, modified Look-Locker inversion recovery imaging (MOLLI) has been used for T1 mapping and measurement of the ECV for the assessment of myocardial fibrosis.

COPD advances in left ventricular diastolic dysfunction.

Background: COPD is concomitantly present in ~30% of patients with heart failure. Here, we investigated the pulmonary function test parameters for left ventricular (LV) diastolic dysfunction and the relationship between pulmonary function and LV diastolic function in patients with COPD.

Patients And Methods: Overall, 822 patients who underwent a pulmonary function test and echocardiography simultaneously between January 2011 and December 2012 were evaluated.

Homoeologous copy-specific expression patterns of MADS-box genes for floral formation in allopolyploid wheat.

The consensus model for floral organ formation in higher plants, the so-called ABCDE model, proposes that floral whorl-specific combinations of class A, B, C, D, and E genes specify floral organ identity. Class A, B, C, D and E genes encode MADS-box transcription factors; the single exception being the class A gene APETALA2. Bread wheat (Triticum aestivum) is a hexaploid species with a genome constitution AABBDD; the hexaploid originated from a cross between tetraploid T.

Quantitative trait locus analysis for flowering-related traits using two F2 populations derived from crosses between Japanese common wheat cultivars and synthetic hexaploids.

Flowering time is an important trait for Japanese wheat breeding. Aegilops tauschii, the D-genome donor of hexaploid wheat, is a useful resource to enlarge the D-genome diversity of common wheat. Previously, we identified flowering-related QTLs in F2 populations of synthetic hexaploid wheat lines between the tetraploid wheat cultivar Langdon and Ae.

Incidence and predictors of in-hospital non-cardiac death in patients with acute heart failure.

Background: Patients with acute heart failure (AHF) commonly have multiple co-morbidities, and some of these patients die in the hospital from causes other than aggravated heart failure. However, limited information is available on the mode of death in patients with AHF. Therefore, the present study was performed to determine the incidence and predictors of in-hospital non-cardiac death in patients with AHF, using the Acute Decompensated Heart Failure Syndromes (ATTEND) registry Methods: The ATTEND registry included 4842 consecutive patients with AHF admitted between April 2007-September 2011.

Impact of Brain Natriuretic Peptide, Calcium Channel Blockers, and Body Mass Index on Recovery Time from Left Ventricular Systolic Dysfunction in Patients With Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TC) is generally recognized to have a good prognosis, but it can be rarely aggravated. We sought to investigate the clinical characteristics of TC and to evaluate the effects of clinical parameters on predicting delayed recovery. We enrolled consecutive patients with TC admitted to our hospital from January 1991 to January 2014.

Impact of β-blocker selectivity on long-term outcomes in congestive heart failure patients with chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease (COPD) is present in approximately one-third of all congestive heart failure (CHF) patients, and is a key cause of underprescription and underdosing of β-blockers, largely owing to concerns about precipitating respiratory deterioration. For these reasons, the aim of this study was to evaluate the impact of β-blockers on the long-term outcomes in CHF patients with COPD. In addition, we compared the effects of two different β-blockers, carvedilol and bisoprolol.

Impact of sleep-disordered breathing and efficacy of positive airway pressure on mortality in patients with chronic heart failure and sleep-disordered breathing: a meta-analysis.

Backgrounds: To conduct a meta-analysis to investigate whether sleep-disordered breathing (SDB) is an independent risk factor for mortality and whether positive airway pressure (PAP) decreases mortality in patients with chronic heart failure (HF). The impact of SDB and the effects of PAP on mortality in patients with chronic HF remain unclear.

Methods: We searched the MEDLINE, EMBASE, and Cochrane databases.
