Iryna Trofymchuk, Nadiia Roik, Lyudmila Belyakova
In this research, we report on the synthesis of mesoporous silicas with various quantities of immobilized oligosaccharide groups and different pore ordering degree. The hydrothermal co-condensation of tetraethyl orthosilicate and β-cyclodextrin-containing organosilane in the presence of cetyltrimethylammonium bromide template was employed. The purpose of this investigation was to show the opportunity of increasing β-cyclodextrin content in silica matrix by changing the molar ratio of initial reagents during organosilane synthesis and to determine whether the enhancing of immobilized groups on the surface influences on model aromatic compound adsorption from water...

Jesse Kigozi, Sue Jowett, Martyn Lewis, Pelham Barton, Joanna Coast
The friction cost approach has been proposed as an alternative to the human capital approach in estimating productivity costs. However, it is difficult, in practice, to apply this approach due to limited availability of context-specific data. Using national and firm-level data on vacancy durations sourced from 4 organisations, we estimated vacancy durations, and consequently, length of friction period for the United Kingdom disaggregated by occupational classification. We found comparable estimates to previously reported friction periods elsewhere...

Mental imagery in experts has been documented in visual arts, music and dance. Here, we examined this issue in an understudied art domain, namely culinary arts. Previous research investigating mental imagery in experts has reported either a stronger involvement of the right hemisphere or bilateral brain activation. The first aim of our study was to examine whether culinary arts also recruit such a hemispheric pattern specifically during odor mental imagery. In a second aim, we investigated whether expertise effects observed in a given sensory domain transfer to another modality...

Preclinical Research Human adrenomedullin (hAM), a hypotensive peptide, also has anti-inflammatory effects. hAM can reduce the severity of the dextran sulphate sodium (DSS)- and 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in animal models. Furthermore, in a clinical study, hAM treatment reduced the Disease Activity Index in ulcerative colitis. However, these therapeutic effects required continuous administration of hAM as the half-life of native hAM is quite short in blood. To resolve this problem, hAM N-terminal was conjugated with two kinds of polyethylene glycol (PEG); 5 kDa PEG or 60 kDa PEG (5 kDa PEG-hAM and 60 kDa PEG-hAM respectively)...

BACKGROUND: Diabetes mellitus (DM) patients with comorbid hypertension (HTN) are at a higher risk of developing microvascular and macrovascular DM complications. Through guideline-driven recommendations, angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are highly recommended for these patients. Unfortunately, medication adherence to these products, though crucial to achieving therapeutic benefit, is frequently suboptimal. Motivational interviewing (MI) is a patient-centered collaborative communication style that is used to strengthen internal motivation for change that may prove effective in enhancing adherence...

BACKGROUND: Use of high-risk medications in the elderly (HRME) and drug-disease (Rx-DIS) interactions in the elderly, as defined by the Healthcare Effectiveness Data and Information Set (HEDIS) Measures, are significantly associated with mortality, hospital admission, and need for emergency care. No published studies to date evaluate interventions to reduce the use of HEDIS-defined HRME, although many studies have postulated a beneficial effect of such interventions. OBJECTIVE: To evaluate the effect of pharmacist interventions on use of HRME and Rx-DIS interactions in the outpatient elderly population...

BACKGROUND: In 2012, hydrocodone combination products (HCPs) were the most prescribed medications in the United States. Under the Controlled Substance Act of 1970, hydrocodone alone was classified as a Schedule II drug, while HCPs were classified as Schedule III, indicating a lower risk for abuse and misuse. However, according to a Drug Enforcement Agency analysis, the addition of nonopioids has not been shown to diminish abuse potential of hydrocodone. In response to concerns for drug abuse and overdose, the Drug Enforcement Agency rescheduled HCPs to Schedule II in October 2014, with the intent of limiting overprescribing and increasing awareness of their abuse potential...

Autism spectrum disorder is a complex trait with a high degree of heritability as well as documented susceptibility from environmental factors. In this study the contributions of copy number variation, exposure to air pollutants, and the interaction between the two on autism risk, were evaluated in the population-based case-control Childhood Autism Risks from Genetics and Environment (CHARGE) Study. For the current investigation, we included only those CHARGE children (a) who met criteria for autism or typical development and (b) for whom our team had conducted both genetic evaluation of copy number burden and determination of environmental air pollution exposures based on mapping addresses from the pregnancy and early childhood...

MicroRNAs (miRs) are important regulators of a wide range of biological processes. Antagomir studies suggest an implication of miR-132 in the functionality of the mammalian circadian clock. miR-212 and miR-132 are tandemly processed from the same transcript and share the same seed region. We found the clock modulator miR-132 and miR-212 to be expressed rhythmically in the central circadian clock. Consequently, mRNAs implicated in circadian functions may likely be targeted by both miRs. To further characterize the circadian role we generated mice with stable deletion of the miR-132/212 locus and compared the circadian behavior of mutant and wild-type control animals on two genetic backgrounds frequently used in chronobiological research, C57BL/6N and 129/Sv...

BACKGROUND: Selenium and coenzyme Q10 is essential for important cellular functions. A low selenium intake is reported from many European countries, and the endogenous coenzyme Q10 production is decreasing in the body with increasing age. Supplementation with selenium and coenzyme Q10 in elderly have shown reduced cardiovascular mortality and reduced levels of markers of inflammation. However, microRNA analyses could give important information on the mechanisms behind the clinical effects of supplementation...

Pycnogenol (PYC), an extract of pine bark, is known to have photoprotective, antimicrobial, antioxidant, and anti-inflammatory properties. An in vivo study was conducted to evaluate the effects of PYC treatment on wound healing in 48 adult male Sprague-Dawley rats, of which 24 were injected with a single dose of alloxan to induce diabetes. Three (3) excisional skin wounds (1.3 cm x 1.3 cm x 2 mm) were created in each healthy and diabetic animal. One (1) wound in each animal was left untreated, 1 was treated daily with a cleanser (ethacridine lactate) and covered with silver sulfadiazine (SSD), and 1 was treated with PYC powder (30 mg)...

BACKGROUND: This is an updated version of the original Cochrane review published in 2013, Issue 4.Low-grade gliomas (LGG) constitute a class of slow-growing primary brain neoplasms. Patients with clinically and radiographically suspected LGG have two initial surgical options, biopsy or resection. Biopsy can provide a histological diagnosis with minimal risk but does not offer a direct treatment. Resection may have additional benefits such as increasing survival and delaying recurrence, but is associated with a higher risk for surgical morbidity...
