BackgroundFor the treatment of chronic heart failure （HF）, both pharmacological and non-pharmacological treatment should be em-ployed in HF patients. Although HF is highly prevalent in nursing home residents, it is not clear whether the recommendations in the guide-lines for pharmacological therapy also are followed in nursing home residents. The aim of this study is to investigate how HF is treated in nursing home residents and to determine to what extent the current treatment corresponds to the *** home resi-dents of five large nursing home care organizations in the southern part of the Netherlands with a previous diagnosis of HF based on medical records irrespective of the left ventricle ejection fraction （LVEF） were included in this cross-sectional design study. Data were gathered on the （medical） records, which included clinical characteristics and pharmacological- and non-pharmacological treatment. Echocardiography was used as part of the study to determine the *** of 501 residents, 112 had a diagnosis of HF at inclusion. One-third of them received an ACE-inhibitor and 40% used aβ-blocker. In 66%, there was a prescription of diuretics with a preference of a loop diuretic. Focusing on the residents with a LVEF￡ 40%, only 46% of the 22 residents used an ACE-inhibitor and 64% aβ-blocker. The median daily doses of prescribed medication were lower than those that were recommended by the guidelines. Non-pharmacological interventions were recorded in almost none of the residents with *** recommended medical therapy of HF was often not prescribed; if pre-scribed, the dosage was usually far below what was recommended. In addition, non-pharmacological interventions were mostly not used at all.

Probiotics in hepatology

World Journal of Gastroenterology 2011年第24期17卷 2890-2896页

作者： jan Lata jana Jurankova Marcela Kopacova Petr Vitek Department of Internal Medicine Faculty of Medicine and University HospitalOstrava University Department of Clinical Microbiology University Hospital Brno 2nd Department of Medicine Charles University in PrahaFaculty of Medicine at Hradec KraloveUniversity Teaching Hospital

The paper provides a basic review of intestinal microflora and its importance in liver diseases. The intestinal microflora has many important functions, above all to maintain the microbial barrier against established as well as potential pathogens. Furthermore, it influences the motility and perfusion of the intestinal wall, stimu- lates the intestinal immune system and therefore also the so-called common mucosal immune system, reducing bacterial translocation and producing vitamins. Immune homeostasis at mucosal level results from a controlled response to intestinal luminal antigens. In liver cirrhosis, there are many changes in its function, mostly an increase in bacterial overgrowth and translocation. In this review, probiotics and their indications in hepatology are generally discussed. According to recent knowledge, these preparations are indicated in clinical practice only for cases of hepatic encephalopathy. Probiotics are able to decrease the permeability of the intestinal wall, and decrease bacterial translocation and endotoxemia in animal models as well as in clinical studies, which is extremely important in the prevention of complications of liver cirrhosis and infection after liver transplantation. Probiotics could limit oxidative and inflammatory liver damage and, in some situations, improve the histological state, and thus non-alcoholic steatohepatitis could be considered as another possible indication.

Impact of post-ruminally infused macronutrients on bovine mammary gland expression of genes involved in fatty acid synthesis, energy metabolism, and protein synthesis measured in RNA isolated from milk fat

Background: Characterising the regulation of milk component synthesis in response to macronutrient supply is critical for understanding the implications of nutritional interventions on milk production. Gene expression in mammary gland secretory cells was measured using RNA isolated from milk fat globules from 6 Holstein-Friesian cows receiving 5-d abomasal infusions of saline, essential amino acids(AA), or glucose(GG) or palm olein(LG)without(LAA) or with(HAA) essential AA, according to a 6 × 6 Latin square design. RNA was isolated from milk fat samples collected on d 5 of infusion and subjected to real-time quantitative PCR. We hypothesised that m RNA expression of genes involved in de novo milk fatty acid(FA) synthesis would be differently affected by GG and LG,and that expression of genes regulating transfer of tricarboxylic acid cycle intermediates would increase at the HAA level. We also hypothesised that the HAA level would affect genes regulating endoplasmic reticulum(er)homeostasis but would not affect genes related to the mechanistic target of rapamycin complex 1(m TORC1) or the integrated stress response(ISR) ***: Infusion of GG did not affect de novo milk FA yield but decreased expression of FA synthase(FASN).Infusion of LG decreased de novo FA yield and tended to decrease expression of acetyl-Co A carboxylase 1(ACC1).The HAA level increased both de novo FA yield and expression of ACC1, and tended to decrease expression of mitochondrial phosphoenolpyruvate carboxykinase(PCK2). m RNA expression of m TORC1 signaling participants was not affected by GG, LG, or AA level. Expression of the ε subunit of the ISR constituent eukaryotic translation initiation factor 2 B(EIF2 B5) tended to increase at the HAA level, but only in the presence of LG. X-box binding protein 1(XBP1) m RNA was activated in response to LG and the HAA ***: Results show that expression of genes involved in de novo FA synthesis responded to glucogenic,lipogenic, and

Journal of Rare Earths 2012年第3期30卷 262-268页

The complexes of 3-methoxy-2-nitrobenzoates of Pr（Ⅲ）, Nd（Ⅲ）, Sm（Ⅲ）, Eu（Ⅲ）, Gd（Ⅲ）, Tb（Ⅲ）, er（Ⅲ） and Tm（Ⅲ） with the formula： Ln（C8H6NO5）3·2H2O, where Ln=lanthanides（Ⅲ）, were synthesized and characterized by elemental analysis, Forier transform irtrared （FTIR） spectroscopy, magnetic and thermogravimetric studies and also by X-ray diffraction （XRD） measurements. The complexes had col- ours typical for Ln（Ⅲ） ions. The carboxylate groups bound as bidentate chelating. On heating to 1173 K in air they decomposed in the same way, at first, dehydrated in one step to anhydrous salts, and then decomposed to the oxides of respective metals with intermediate formation of the oxycarbonates. The enthalpy values of the dehydration process changed from 133.72 to 44.50 kJ/mol. Their solubility in water at 293 K was of the order of 10-4 mol/dm3. The magnetic moments of analysed complexes were determined by Gouy＇s method in the range of 76-303 K.
