This review summaries the utility, application and data supporting use of cardiac magnetic resonance imaging (CMR) to evaluate and quantitate aortic regurgitation. We systematically searched Medline and PubMed for original research articles published since 2000 that provided data on the quantitation of aortic regurgitation by CMR and identified 11 articles for review. Direct aortic measurements using phase contrast allow quantitation of volumetric flow across the aortic valve and are highly reproducible and accurate compared with echocardiography...

Failure of the right ventricle (RV) is a serious disease with a poor prognosis and limited treatment options. Signaling by α1-adrenergic receptors (α1-ARs), in particular the α1A-subtype, mediate cardioprotective effects in multiple heart failure models. Recent studies show that chronic treatment with the α1A-subtype agonist A61603 improves function and survival in a model of LV failure. The goal of this study was to determine if chronic A61603 treatment is beneficial in a RV failure model. We used tracheal instillation of the fibrogenic antibiotic bleomycin in mice to induce pulmonary fibrosis, pulmonary hypertension, and RV failure within 2 wk...

Exhaled breath condensate (EBC) is easily obtained for clinical diagnosis and prognosis for pulmonary diseases and has gained much interest in biomarker discovery research and studies. Lactate, a physiological material, is found in EBC and has been demonstrated to be a potential indicator of chronic obstructive pulmonary disease and other lung diseases. Several assays are available to detect lactate in human body fluids, and yet none is suitable for detecting lactate in EBC. Due to the very low concentration of lactate in EBC and low volume of EBC, it is very important to develop an assay to measure lactate with high sensitivity, accuracy and easy sample processing...

With respect to hazard classification for developmental toxicity under the CLP Regulation it is important to consider the possible influence of maternal toxicity. The aim of the present review was to characterize to which extent developmental effects could be caused by non-specific maternal toxicity. Such effects would not be relevant for classification. In prenatal developmental toxicity studies, the administration of high doses is given in the guideline. The associated non-specific systemic toxicity often affects the maternal body weight...

The purpose of this study was to investigate the influences of NCX 2121, a nitric oxide (NO)-releasing derivative of indomethacin, upon the generation of proinflammatory mediators using murine macrophages activated by lipopolysaccharide (LPS) isolated from Prevotella intermedia, which is one of the pathogens implicated in periodontal diseases. Inducible NO synthase (iNOS)-derived NO, IL-1β and IL-6 as well as their relevant mRNA were significantly attenuated by NCX 2121 in RAW264.7 cells activated by P. intermedia LPS...

Quercetin (Qu) is known as a dietary antioxidant with numerous bioactivities, but its function in anti-cancer has not been fully investigated. Here, we show that Qu at low doses (≤10μM) significantly enhances the inhibition of 10-hydroxy camptothecin (HCPT) on the proliferation of MCF7, BGC823 and HepG2 cells. A plasmid DNA relaxation assay indicates that the inhibition of HCPT on the catalytic activity of topoisomerase I (Topo I) is increased by Qu at 10μM. Compared to the treatment by Qu or HCPT alone, phosphorylation at Ser(139) of γH2A...

Converging evidence from studies with animal models and humans suggests that early developmental exposure to polychlorinated biphenyls (PCBs) leads to deficits in cognitive flexibility and inhibitory control. These processes are mediated to a large extent by the prefrontal cortex, thus we examined the effects of PCB exposure during adolescence-a period of robust prefrontal cortical development-on both processes. Specifically, we used operant set-shifting and differential reinforcement of low rates of responding (DRL) tasks to assess cognitive flexibility and response inhibition, respectively...

OBJECTIVE: Appendicovesicostomy (APV) and Monti ileovesicostomy (Monti) are durable catheterizable channels. While subfascial revision rates vary by channel type, a channel implanted in the anterior (vs posterior) aspect of the bladder may have a lower subfascial revision risk, due to decreased channel mobility and better fascial fixation. The present study aimed to compare long-term durability of anteriorly compared to posteriorly implanted APV and Monti channels in a large international cohort...

REVIEW
M Beatriz S Lopes
The 4th edition of the World Health Organization (WHO) classification of endocrine tumors has been recently released. In this new edition, major changes are recommended in several areas of the classification of tumors of the anterior pituitary gland (adenophypophysis). The scope of the present manuscript is to summarize these recommended changes, emphasizing a few significant topics. These changes include the following: (1) a novel approach for classifying pituitary neuroendocrine tumors according to pituitary adenohypophyseal cell lineages; (2) changes to the histological grading of pituitary neuroendocrine tumors with the elimination of the term "atypical adenoma;" and (3) introduction of new entities like the pituitary blastoma and re-definition of old entities like the null-cell adenoma...

Both negative and positive social experiences during sensitive life phases profoundly shape brain and behaviour. Current research is therefore increasingly focusing on mechanisms mediating the interaction between varying life experiences and the epigenome. Here, male mice grew up under either adverse or beneficial conditions until adulthood, when they were subdivided into groups exposed to situations that either matched or mismatched previous conditions. It was investigated whether the resulting four life histories were associated with changes in anxiety-like behaviour, gene expression of selected genes involved in anxiety and stress circuits, and arginine vasopressin receptor 1a (Avpr1a) gene methylation...

Apolipoprotein A-IV (apoA-IV) has been observed to be associated with lipids, kidney function, adiposity- and diabetes-related parameters. To assess the causal relationship of apoA-IV with these phenotypes, we conducted bidirectional Mendelian randomization (MR) analyses using publicly available summary-level datasets from GWAS consortia on apoA-IV concentrations (n = 13,813), kidney function (estimated glomerular filtration rate (eGFR), n = 133,413), lipid traits (HDL cholesterol, LDL cholesterol, triglycerides, n = 188,577), adiposity-related traits (body-mass-index (n = 322,206), waist-hip-ratio (n = 210,088)) and fasting glucose (n = 133,010)...

Mechanical loading is necessary for the development and maintenance of the musculoskeletal system. Removal of loading via microgravity, paralysis, or bed rest leads to rapid loss of muscle mass and function; however, the molecular mechanisms that lead to these changes are largely unknown, particularly for the spaceflight (SF) microgravity environment. Furthermore, few studies have explored these effects on the shoulder, a dynamically stabilized joint with a large range of motion; therefore, we examined the effects of microgravity on mouse shoulder muscles for the 15-d Space Transportation System (STS)-131, 13-d STS-135, and 30-d Bion-M1 missions...
