The existing form of an ionizable organic compound can simultaneously affect its soil adsorption and plant bioactivity. In this experiment, the adsorption and bioactivity of two weak acid herbicides (WAHs), imazethapyr and 2,4-D, were studied to explore the predominant mechanism by which the soil pH and the addition of biochar can influence the phytotoxicity of WAHs in soil. Then, the WAH concentration extracted by hollow fiber-based liquid-phase microextraction (CHF-LPME ), the in situ pore water concentration (CIPW ) and the added concentration (CAC ) were employed to estimate the phytotoxicity...

OBJECTIVE: This article investigated the changes of some biochemical markers and cardiac function in chronic heart failure (CHF), and provided the basis for the diagnosis of CHF. METHODS: New Zealand rabbit CHF model was established using adriamycin (ADR). Twenty New Zealand rabbits were randomly divided into model group ( n =15) and control group ( n =5), injected with ADR and saline solution via the ear vein respectively, 2 times a week, lasting for 8 weeks. After that, myocardial enzymes, carotid artery pressure, echocardiogram (ECG) and phonocardiogram (PCG) of all New Zealand rabbits were detected and recorded...

Introduction: Autosomal recessive polycystic kidney disease (ARPKD) is a severe hepatorenal disorder of childhood. Early renal disease in ARPKD may require renal replacement therapy and is associated with failure to thrive resulting in a need for nasogastric tube feeding or gastrostomy. In ARPKD patients, the benefit of a gastrostomy in nutrition and growth needs to be weighed against the potential risk of complications of congenital hepatic fibrosis (CHF) and portal hypertension like variceal bleeding. CHF in ARPKD has thus been considered as a relative contraindication for gastrostomy insertion...

The benefits of renin angiotensin-aldosterone system inhibitors (RAASi) are well-established in the general population, particularly among those with diabetes, congestive heart failure (CHF), or coronary artery disease (CAD). However, conflicting evidence from trials and concerns about hyperkalemia limit RAASi use in hemodialysis patients, relative to other antihypertensive agents, including beta blockers and calcium channel blockers. Therefore, we investigated prescription patterns and associations with mortality for RAASi and other antihypertensive agents using data from the international Dialysis Outcomes and Practice Patterns Study (DOPPS)...

BACKGROUND: Whether the clinical presentation and in particular prevalence of symptoms and signs of heart failure (HF) is different in elderly versus younger patients and in those with reduced (HFrEF) versus preserved (HFpEF) left ventricular ejection fraction (LVEF) is a matter of ongoing debate. AIMS: To compare detailed clinical characteristics of these important subgroups and to develop a prediction rule for the differentiation of HFpEF and HFrEF based on clinical parameters...

BACKGROUND: Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement has shown early promise in patients deemed poor surgical candidates as a less invasive alternative to conventional reoperative mitral valve (MV) replacement. OBJECTIVE: This retrospective, single-center study reviewed the procedural outcomes of all TMVIV and TMVIR procedures between 2013-2018 at a large tertiary referral center serving the southeastern United States. An analysis of patient safety measures was also performed, with a retrospective assessment of relative procedural safety that included preoperative risk stratification and postoperative mortality predictors, operative time, average blood loss, length of hospital stay, and readmission rates...

Background: The reactive oxygen metabolites (d-ROMs) test has recently been explored as a novel marker of oxidative stress in vivo and used in clinical settings. Conversely, data regarding the utility of the d-ROMs test as a predictor of patients with chronic heart failure (CHF) are limited. This prospective study aims to elucidate the efficacy of the d-ROMs test as a predictor of initial heart failure (HF) hospitalization in elderly patients with CHF. Methods: A total of 428 elderly outpatients with CHF with no history of HF hospitalization (108 males, 320 females; mean age, 75 ± 7 years) were enrolled...

Neutrophil‑to‑lymphocyte ratio (NLR) is commonly considered a useful prognostic index for many cardiovascular diseases; however, it has limited sensitivity and specificity. Factors associated with elevated NLR may aid in the prediction of prognosis with heart failure (HF) in combination with NLR. The present study sought to identify decisive factors associated with NLR in HF patients and investigate their association with elevated NLR. The gene expression profile for blood samples from 197 individuals with chronic heart failure (CHF), with corresponding hematological parameters and clinical data were obtained from the public database, GSE77343...

Activation of the Ca2+ /calmodulin-dependent protein kinase II isoform δA (CaMKIIδA) disturbs intracellular Ca2+ homeostasis in cardiomyocytes during chronic heart failure (CHF). We hypothesized that upregulation of CaMKIIδA in cardiomyocytes might enhance Ca2+ leak from the sarcoplasmic reticulum (SR) via activation of phosphorylated ryanodine receptor type 2 (P-RyR2) and decrease Ca2+ uptake by inhibition of SR calcium ATPase 2a (SERCA2a). In this study, CHF was induced in rats by ligation of the left anterior descending coronary artery...

BACKGROUND: Any acute event, either primary or secondary to a chronic disease, is generally followed by some degree of physical impairment. The Sub-Acute Care (SAC) represents one of the inpatient intermediate care settings aimed at completing recovery and restoring functional capacity. Debate exists on the role of the rehabilitation treatment in the SAC setting. AIM: To compare the outcomes of patients managed in two different SAC Units where A) patients undergo an individualized rehabilitation program on top of optimal medical therapy (OMT) B) patients receive OMT only...

BACKGROUND: Prior studies suggest that the relationship between hypothyroidism and mortality is dependent on underlying cardiovascular risk. Little is known about the association of hypothyroidism with hospitalization risk, and how these associations are modified by cardiovascular status. METHODS: We examined the association of thyroid status, defined by serum thyrotropin (TSH), with hospitalization risk among patients who received care from a large university-based tertiary care center over 1990-2015...

Treatment with anti-TNF-α (tumor necrosis factor), one of the pivotal cytokines, was introduced to clinical practice at the end of last century and revolutionized the treatment of rheumatoid arthritis (RA) as well as many other inflammatory conditions. Such a treatment may however bring many safety issues regarding infections, tuberculosis, as well as cardiovascular diseases, including heart failure. Given the central role of proinflammatory cytokines in RA, atherosclerosis, and congestive heart failure (CHF), such a treatment might result in better control of the RA process on the one side and improvement of heart function on the other...

Cardiac transplantation is the gold standard treatment for patients with advanced congestive heart failure that is refractory to maximal medical therapy. However, donor heart availability remains the major limiting factor, resulting in a large number of patients waiting long periods of time before transplantation. As a result, mechanical circulatory support devices have been increasingly used as a 'bridge' in order to sustain organ function and stabilise haemodynamics while patients remain on the transplant waiting list or undergo left ventricular assist device surgery...

We examine the DNA polymerase β (pol β) transition state from a leaving group presteady-state kinetics perspective by measuring the rate of incorporation of dNTPs and corresponding novel β,γ-CXY-dNTP analogues, including individual β,γ-CHF and -CHCl diastereomers with defined stereochemistry at the bridging carbon, during the formation of right (R) and wrong (W) base pairs. Brønsted plots of log kpol vs pKa4 of the leaving group bisphosphonic acids are used to interrogate the effects of base identity, dNTP analogue leaving group basicity, and the precise configuration of the C-X atom in R and S stereoisomers on the rate-determining step (kpol )...
