Functional mitral regurgitation in patients with heart failure and depressed ejection fraction.

Functional mitral regurgitation (FMR) is a common complication of left ventricular dysfunction. It is now recognized as an important clinical entity and an independent predictor of poor prognosis in cardiomyopathy patients. In this review, we provide a comprehensive summary of the pathophysiology, latest imaging modalities, and diagnostic criteria for FMR. Additionally, we discuss the recent literature on the continuously evolving surgical and percutaneous treatment options.

Is there a need to assess myocardial viability in patients presenting with heart failure?

Cardiac MRI is unique amongst the cardiac imaging modalities in its ability to directly image myocardial fibrosis using late gadolinium enhancement techniques. The ability to identify not only the presence of fibrosis but also its pattern of distribution within the myocardium can aid in distinguishing between ischemic and nonischemic causes of left ventricular dysfunction, as well as provide valuable prognostic information for patients with various etiologies of heart failure.

This review is an update to the American College of Gastroenterology (ACG) Committee on Minority Affairs and Cultural Diversity's paper on colorectal cancer (CRC) in African Americans published in 2005. Over the past 10 years, the incidence and mortality rates of CRC in the United States has steadily declined. However, reductions have been strikingly much slower among African Americans who continue to have the highest rate of mortality and lowest survival when compared with all other racial groups. The reas...

Do women with smaller breasts perform better in long-distance running?

Literature has established that a range of physiological, biomechanical, and training variables influence marathon performance. The influence of anthropometric characteristics has also received attention. However, despite major marathons exceeding 40,000 participants and approximately a third of these runners being female, no data exist on the influence of the breast on running performance. This cross-sectional study aimed to explore the impact of breast mass on marathon finish time. One hundred and sixty-e...

Eosinophilic esophagitis: current perspectives from diagnosis to management.

Eosinophilic esophagitis (EoE) is a chronic antigen-mediated immune disease of the esophagus characterized by symptoms related to esophageal dysfunction, as well as significant esophageal eosinophilia. Although dense eosinophilia is the hallmark of EoE, other characteristic histologic features have been described that may help distinguish EoE from other competing diagnoses, although none are specific to EoE. One or more foods and, at times, environmental allergens trigger EoE. Left untreated, esophageal inf...

In an effort to help identify factors that maintain heavy smoking, this study tested the association of pretreatment cigarette use (cigarettes per day) with striatal dopamine release during smoking-cessation treatment.

NEDD4 Depletion Inhibits Hepatocellular Carcinoma Growth via Targeting PTEN.

Neural precursor cell-expressed developmentally down-regulated gene 4 (NEDD4) plays an important role in tumor cell growth, yet its role in hepatocellular carcinoma (HCC) remains unclear. This study is to establish NEDD4 as a prognostic biomarker by which the survival of HCC patients can be predicted and to reveal the role of NEDD4 in hepatocellular carcinoma cell growth.

Testicular growth and spermatogenesis: new goals for pubertal hormone replacement in boys with hypogonadotrophic hypogonadism? A multicentre prospective study of hCG/rFSH treatment outcomes during adolescence.

Testosterone treatment for pubertal induction in boys with hypogonadotrophic hypogonadism (HH) provides virilisation, but does not induce testicular growth or fertility. Larger studies evaluating the outcomes of gonadotrophin replacement during adolescence have not been reported to date; whether previous testosterone substitution affects testicular responses is unresolved. We aimed to assess the effects of human chorionic gonadotrophin (hCG) and recombinant FSH (rFSH) in boys and adolescents with HH with re...

3-Hydroxy-4-nitrobenzoic Acid as a MALDI Matrix for In-Source Decay.

In-source decay (ISD) in matrix-assisted laser desorption/ionization (MALDI) is a rapid sequencing method for peptides. 1,5-Diaminonaphthalene (1,5-DAN) is a most frequently used matrix for ISD. However, using 1,5-DAN generates mainly c- and z-series ions by N-Cα bond cleavage, which makes it difficult to distinguish leucine (Leu) and isoleucine (Ile), and frequently lacks c(n-1)-series ions owing to proline (Pro) at residues n. Several oxidizing matrices generating a- and x-series ions accompanied by d-se...

Construction of the 1,5-Benzodiazepine Skeleton from o-Phenylendiamine and Propargylic Alcohols via a Domino Gold-Catalyzed Hydroamination/Cyclization Process.

The gold-catalyzed reaction of o-phenylendiamine with propargylic alcohols affords 1,5-benzodiazepines bearing different substituents on the 2 and 4 positions. The method allows even for the selective preparation of 4-substituted 1,5-benzodiazepine derivatives.

Infrared Spectroscopic Investigation of the Acidic CH Bonds in Cationic N-Alkanes: Pentane, Hexane, and Heptane.

Radical cations of n-alkanes (pentane, hexane, and heptane) in the gas phase are investigated by infrared predissociation spectroscopy with the argon or nitrogen tagging. All trans and gauche-involving conformers are identified for these cations by comparisons of observed infrared spectra and vibrational simulations. Intense CH stretch bands are observed in the frequency region lower than the normal alkyl CH stretch frequency. These low frequencies and high intensities of the CH stretch bands are caused by ...

A significant correlation was found between arsenic and antimony, and calcium...

Rice root curling, a response to mechanosensing, is modulated by the rice E3-ubiquitin ligase HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE1 (OsHOS1).

Plant development depends on the perception of external cues, such as light, gravity, touch, wind or nutrients, among others. Nevertheless, little is known regarding signal transduction pathways integrating these stimuli. Recently, we have reported the involvement of a rice E3-ubiquitin ligase (OsHOS1, HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE1), previously associated with abiotic stress response, in root responses to mechanical stimuli. We showed that OsHOS1 is involved in the regulation of root curli...
