A novel type of magnetic molecularly imprinted polymers was prepared for the selective enrichment and isolation of chelerythrine from Macleaya cordata (Willd) R. Br.. The magnetic molecularly imprinted polymers were prepared using functional Fe3 O4 @SiO2 as a magnetic support, chelerythrine as template, methacrylic acid as functional monomer, and ethylene glycol dimethacrylate as cross-linker. Density functional theory at the B3LYP/6-31G (d, p) level with Gaussian 09 software was applied to calculate the interaction energies of chelerythrine, methacrylic acid and the complexes formed from chelerythrine and methacrylic acid in different ratios...

Treatment of oblique and spiral fractures remains challenging. The aim of this study was to introduce and investigate the new LagLoc technique for locked plating with generation of interfragmentary compression, combining the advantages of lag-screw and locking-head-screw techniques. Oblique fracture was simulated in artificial diaphyseal bones, assigned to three groups for plating with a 7-hole locking compression plate. Group I was plated with three locking screws in holes 1, 4 and 7. The central screw crossed the fracture line...

AIMS: To examine sleep quality and its associations with glycemic control, glycemic variability and fear of hypoglycemia in adults with type 1 diabetes. BACKGROUND: Poor sleep quality has negative health consequences and is a frequent complaint among adults with type 1 diabetes. Sleep quality in adults with type 1 diabetes is likely affected by glucose levels as well as stressors associated with managing a chronic condition. DESIGN: A retrospective secondary analysis of pooled data from two previous cross-sectional studies was conducted...

BACKGROUND: Exhaled breath condensate (EBC) analysis is a non-invasive method to assess the lower respiratory tract. In humans, EBC hydrogen peroxide (H2 O2 ), pH and leukotriene B4 (LTB4 ) are useful for detection and monitoring of inflammatory lung diseases, including asthma. OBJECTIVES: To determine associations between EBC biomarkers and cytological and endoscopic definitions of lower airway inflammation whilst controlling for sampling and environmental variables...

Background: Dengue is the most important arboviral disease in the world. Seroprevalence has been proposed as a marker of endemicity, however, studies are scarce. Methods: We conducted a cross-sectional, stratified cluster, random sample study to measure the seroprevalence of antibodies to dengue virus (DENV) in Mexico. The target population was school children ages 6-17 y from 22 endemic states in Mexico, clustered in four regions: Pacific, South-Central, Southeast and Low...

Background: Studies have demonstrated that statin therapy decreases the growth rate of abdominal aneurysms. However, the effect of statin therapy on the proximal aortic disease has not been sufficiently elucidated. Aim: We aimed to analyze the association between statin treatment and the severity of proximal aortopathy in patients with aortic valve disease. Design: Cross-sectional study. Methods: We prospectively identified 458 patients who were referred for aortic valve surgery from 2008 to 2014...

CONTEXT: The early activation of the hypothalamic-pituitary-gonadal axis during infancy can be used in the evaluation of infants suspected of disorders of sex development (DSD). However, few data exists on sex-specific reference ranges for these hormones during early life. OBJECTIVE: To evaluate sex-differences in reproductive hormone concentrations in serum from healthy infants in order to define sex-specific cut-off values and to apply these in infants with DSD...

Background: We aimed to investigate the contribution of chronic conditions to gender differences in disability-free life expectancy (DFLE) and life expectancy with disability (LED) in Belgium in 2001, 2004 and 2008. Methods: Data on disability and chronic conditions from participants of the 2001, 2004 and 2008 Health Interview Surveys in Belgium were used to estimate disability prevalence by cause using the attribution method. Disability prevalence was applied to life tables to estimate DFLE and LED using the Sullivan method...

Background: Mounting evidence has associated high sodium intake with hypertension, cardiovascular disease and stroke. We investigated whether high sodium intake modulates the parameters of endothelial damage, inflammation and oxidative stress. Methods: We used a cross-sectional study design including 223 Chilean subjects (6.9-65.0 years old). We measured aldosterone, renin activity, cortisol, cortisone, adiponectin, leptin, hs-CRP, IL-6, TNF-alpha, PAI-1, metalloproteinase (MMP)-9 and MMP-2 activity and malondialdehyde (MDA)...

Background: Frailty is a risk factor for cardiovascular disease. Underlying mechanisms to explain the connection between frailty and cardiovascular disease are unclear. We sought to examine the association between frailty and arterial stiffness, a precursor of hypertension and cardiovascular disease. Methods: We conducted a cross-sectional analysis of community-dwelling Framingham Heart Study Offspring and Omni participants ≥60 years of age examined in 2005-2008...

Background: Gait speed and cognitive performance tend to decline with age. A better understanding of the dynamics of the association between gait speed and cognitive status may identify preclinical markers and improve diagnostic assessments. The objective was to quantify the association between gait speed and cognitive status in later life. Methods: A systematic search was undertaken of relevant databases for original articles published prior to June 2017, measuring the association between gait speed and cognition cross-sectionally or longitudinally among the community-dwelling population...

AIMS: Despite several studies reporting a higher mortality rate for women undergoing isolated coronary artery bypass graft (CABG) surgery, this issue has not been completely clarified. The aim of the current study was to determine if sex differences in CABG surgery affect adjusted operative results and operative mortality. METHODS: Between January 2005 and December 2012, 3756 consecutive patients (3009 men and 747 women) underwent isolated CABG at our institution...

BACKGROUND/OBJECTIVE: Fibromyalgia (FM) is a chronic pain syndrome of unknown etiology that can include subjective cognitive symptoms and variable evidence of cognitive dysfunction. Rates of occurrence and severity of cognitive impairment remain unclear. Additionally, comparison of this group with other pain conditions has been limited.

BACKGROUND AND AIMS: The guidelines for the insertion and maintenance of the central venous catheter (CVC) in children on long-term parenteral nutrition (PN) were published 12 years ago and studies evaluating the outcomes are limited. Therefore, the aim of this study was to perform a survey about criteria for CVC insertion and maintenance in intestinal failure/rehabilitation centres treating children on home PN. METHODS: An on-line cross-sectional survey based on previous European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) PN guidelines was distributed electronically to the members of the ESPGHAN networking group, Network for Intestinal Failure and Transplantation in Europe (NITE) and tertiary paediatric gastroenterology centres in Europe...

OBJECTIVE: Securing a residency training position in plastic surgery is highly competitive each year with a limited quota of positions and numerous qualified applicants. Although previous studies have highlighted the importance of residency programs and applicants seeking a "good fit," it remains poorly understood what influences a medical student's impression and desire to train at a certain program over others. The objective of this cross-sectional study was to identify which specific potentially modifiable factors during elective rotations and program interviews were most important to Canadian medical students when ranking plastic surgery programs...
