The determination of specific IgE (sIgE) level is of great importance in IgE-mediated food allergies. Our aim was to develop a homogeneous immunoassay-light-initiated chemiluminescent assay (LICA)-for measuring allergen sIgE of a single component in egg white, thus evaluating the LICA-sIgE assay as a useful tool in the diagnosis of food allergy. The LICA-sIgE assay was performed by incubating serum sample with anti-human IgE antibody coated with chemiluminescer beads, streptavidin-coated sensitizer beads, and biotinylated antigens, which consist of four components in egg white...

RATIONALE: Though it is rare, isolated interrupted aortic arch (IAA) could lead to hypertension. Surgical repair is the only effective curative method to treat IAA conditions and patients with IAA can hardly survive to adulthood with medication alone. We report an IAA case that of a 45-year-old male patient who survived for 45 years without surgical treatment. PATIENT CONCERNS: A 45-year-old man was referred to the hospital presenting with abnormal blood pressure level...

Nursing staff in a medical/surgical acute care 34-bed hospital unit were challenged by low percentages of patients able to recall nurse leader rounding activity (NLR). NLR occurred daily for all patients, yet many did not recall visits by nursing leaders when surveyed at discharge. Care giver credibility suffered as non-nursing executives questioned if NLR consistently occurred. Several mechanisms were used to facilitate patient NLR recall: scripted NLR verbiage/keywords, nursing uniform leadership insignia and white lab coats, sharing of business cards, handwritten notes on patient communication white boards, multimedia leadership insignia on leader e-tablets, and visits with family members: patient NLR recall did not improve...

Clinical guidelines in the United States and United Kingdom recommend that individuals with suspected hypertension should have ambulatory blood pressure (BP) monitoring to confirm the diagnosis. This approach reduces misdiagnosis because of white coat hypertension but will not identify people with masked hypertension who may benefit from treatment. The Predicting Out-of-Office Blood Pressure (PROOF-BP) algorithm predicts masked and white coat hypertension based on patient characteristics and clinic BP, improving the accuracy of diagnosis while limiting subsequent ambulatory BP monitoring...

Properties of the hydroxyapatite obtained by electrochemical assisted deposition (ED) are dependent on several factors including deposition temperature, electrolyte pH and concentrations, applied potential. All of these factors directly influence the morphology, stoichiometry, crystallinity, electrochemical behaviour, and particularly the coating thickness. Coating structure together with surface micro- and nano-scale topography significantly influence early stages of the implant bio-integration. The aim of this study is to analyse the effect of pH modification on the morphology, corrosion behaviour and in vitro bioactivity and in vivo biocompatibility of hydroxyapatite prepared by ED on the additively manufactured Ti64 samples...

In view of decreasing lead exposure and guidelines endorsing ambulatory above office blood pressure (BP) measurement, we reassessed association of BP with blood lead (BL) in 236 newly employed men (mean age, 28.6 years) without previous lead exposure not treated for hypertension. Office BP was the mean of five auscultatory readings at one visit. Twenty-four-hour BP was recorded at 15- and 30-minute intervals during wakefulness and sleep. BL was determined by inductively coupled plasma mass spectrometry. Systolic/diastolic office BP averaged 120...

A new antimicrobial bilayer film was developed using chitosan, cellulose, and nisin. Chitosan solution containing nisin (500 and 1000μg/mL) was prepared by sol-gel method and then the solution was coated on cellulose paper by dip coating method. A chitosan-cellulose film without antimicrobial had no inhibitory effect on Listeria monocytogenes, whereas, the incorporation of nisin made a significant increase (P<0.05) in antimicrobial characteristics of the films. Moreover, no significant differences were shown on antimicrobial activity of developed films during the storage at 4°C for one month...

BACKGROUND: Arterial hypertension is very common in chronic kidney disease (CKD) patients and its prevalence increases with lowering estimated glomerular filtration rate (eGFR). Blood pressure (BP) control is a cornerstone in the treatment of CKD patients but still most treatment decisions are based on office BP measurement (OBPM). The aim of this cross-sectional, retrospective study is to investigate the prevalence of hypertension phenotypes in CKD patients and whether different home (HBPM) or OBPM are associated with a different CKD stage and cardiovascular comorbidities...

The exceptionally high cellular uptake of gold nanorods (GNRs) bearing cationic surfactants makes them a promising tool for biomedical applications. Given the known specific toxic and stress effects of some preparations of cationic nanoparticles, the purpose of this study was to evaluate, in an in vitro and in vivo in mouse, the potential harmful effects of GNRs coated with (16-mercaptohexadecyl)trimethylammonium bromide ((MTAB)GNRs). Interestingly, even after cellular accumulation of high amounts of (MTAB)GNRs sufficient for induction of photothermal effect, no genotoxicity (even after longer-term accumulation), induction of autophagy, destabilization of lysosomes (dominant organelles of their cellular destination), alterations of actin cytoskeleton, or in cell migration could be detected in vitro...

We have developed a method to functionalize polystyrene (PS) cell culture plates with hydroxyapatite (HAp) via protein adsorption layers such as human serum albumin (HSA) in simulated body fluids (SBFs). In order to investigate the versatility the method, in this study the effect of protein adsorption layers on HAp deposition on PS plate surfaces in SBF was evaluated. Pretreatments with alternate soaking process (ASP) using solutions containing calcium ions and phosphate ions followed by incubation with SBF for 24 h resulted in HAp deposition on PS plates with adsorption layers of HSA, type I collagen, hen egg white lysozyme, and poly L-glutamic acid, an acidic protein analogue: the deposition behaviors were correlated with adsorption ability and charge state of proteins...

Hyun Chul Park, Isnaeni, Suhyun Gong, Yong-Hoon Cho
Enhancing the fluorescence intensity of colloidal quantum dots (QDs) in case of color-conversion type QD light-emitting devices (LEDs) is very significant due to the large loss of QDs and their quantum yields during fabrication processes, such as patterning and spin-coating, and can therefore improve cost-effectiveness. Understanding the enhancement process is crucial for the design of metallic nanostructure substrates for enhancing the fluorescence of colloidal QDs. In this work, improved color conversion of colloidal green and red QDs coupled with aluminum (Al) and silver (Ag) nanodisk (ND) arrays designed by in-depth systematic finite-difference time domain simulations of excitation, spontaneous emission, and quantum efficiency enhancement is reported...

Arterial stiffness is a marker of vascular damage. Although adiposity increases cardiovascular risk, the relationship between paediatric overweight and arterial stiffness is unclear. The study aimed to evaluate the simultaneous effect of hypertension and overweight on arterial stiffness using cardio-ankle vascular index (CAVI) and related novel, theoretically blood pressure (BP)-independent, index CAVI0. CAVI and CAVI0 were measured in 140 adolescent boys (16.0 ± 1.9 years) divided into age-matched groups: normal-weight normotensives, overweight normotensives, overweight white-coat hypertensives, and overweight essential hypertensives...
