A water-compatible magnetic triclosan (TCS) imprinted material (TCS-CTS-Fe(0)-MIPs) was synthesized for selective enrichment and detection of TCS in real complex water samples. The material was synthesized by using chitosan (CTS) as functional monomer, which has rich surface O- and N-containing functional groups. The TCS imprinted CTS was coated on Fe(0) surface and then cross-linked with glutaraldehyde. Scanning electron microscopy suggested that the imprinted material was covered with a layer of imprinted film, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirmed that the imprinted material had more functional groups (amino and hydroxyl groups) than that of non-imprinted material...

In endoscopic sinus surgery (ESS) synechiae formation and ostial stenosis are frequently encountered. This is not uncommon after frontal recess and ostium interventions due to the narrow recess and difficult anatomy of the region. The goal of this study is to evaluate the efficacy of the new cross-linked hyaluronan gel-PureRegen(®) Gel Sinus-on wound healing and synechiae prevention in endoscopic frontal sinus surgery. The study consists of two groups of patients who underwent ESS, including frontal sinus surgery...

BACKGROUND: Implant failure is a severe and frequent adverse event in all areas of neurosurgery. It often involves infection with biofilm formation, accompanied by inflammation of surrounding tissue, including the brain, and bone loss. The most common bacteria involved are Staphylococcus aureus. We here test whether intraoperative infection of intracranial screws with Staphylococcus aureus would lead to biofilm formation and inflammatory tissue reaction in rats. METHODS: Two titanium screws were implanted in the cranium of Sprague-Dawley rats, anesthetized with xylazine (4 mg/kg) and ketamine (75 mg/kg)...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

REVIEW
Koichiro Matsuno
A reaction cycle in general or a metabolic cycle in particular owes its evolutionary emergence to the covering reaction environment acting as a measurement apparatus of a natural origin. The quantum measurement of the environmental origin underlying the molecular processes observed in the biological realm is operative cohesively between the measuring and the measured. The measuring part comes to pull in a quantum as an indivisible lump available from an arbitrary material body to be measured. The inevitable difference between the impinging quantum upon the receiving end on the part of the environment and the actual quantum pulled into the receiving end comes to effectively be nullified through the retrocausative propagation of the corresponding wave function proceeding backwards in time...

A growing body of research attests to the impact of welfare regimes on health and health equity. However, the mechanisms that link different kinds of welfare entitlement to health outcomes are less well understood. This study analysed the accounts of 29 older adults in England to delineate how the form of entitlement to welfare and other resources (specifically, whether this was understood as a universal entitlement or as targeted to those in need) impacts on the determinants of health. Mechanisms directly affecting access to material resources (through deterring uptake of benefits) have been well documented, but those that operate through psychosocial and more structural pathways less so, in part because they are more challenging to identify...

PURPOSE: Anastomotic or "stitch hole" bleeding is common during vascular surgery with synthetic material such as Dacron or polytetrafluoroethylene (PTFE). Hemostatic adjuncts such as fibrin sealant (FS) may reduce blood loss and operating time in such circumstances. We evaluated the safety and the hemostatic effectiveness of a ready-to-use human plasma-derived FS in vascular surgery. METHODS: Patients with mild / moderate suture line bleeding during elective, open, vascular surgery using synthetic grafts or patches were studied...

The synthesis of thermoset shape memory polymer (SMP) polyurethanes from symmetric, aliphatic alcohols and diisocyanates has previously demonstrated excellent biocompatibility in short term in vitro and in vivo studies, although long term stability has not been investigated. Here we demonstrate that while rapid oxidation occurs in these thermoset SMPs, facilitated by the incorporation of multi-functional, branching amino groups, byproduct analysis does not indicate toxicological concern for these materials...

Napier grass Stunt Disease (NSD) is a severe disease of Napier grass (Pennisetum purpureum) in Eastern Africa, caused by the leafhopper-transmitted bacterium Candidatus Phytoplasma oryzae. The pathogen severely impairs the growth of Napier grass, the major fodder for dairy cattle in Eastern Africa. NSD is associated with biomass losses of up to 70% of infected plants. Diagnosis of NSD is done by nested PCR targeting the phytoplasma DNA, which is difficult to perform in developing countries with little infrastructure...

Mesoporous carbon of cubic structure was functionalized with ethylamine, ethylenediamine, diethylenetriamine and triethylenetetramine at 40°C for 8h. The mesostructure and textural parameters of the new materials were determined by X-ray diffraction and low-temperature nitrogen sorption techniques. The functional groups present on the surface of the samples were identified by FT-IR and thermogravimetric studies. Functionalization of the mesoporous carbon led to reduction of the surface area and pore volume as well as to an increase in the mean pore diameter...

Multiple cortical regions are crucial for perceiving the visual world, yet the processes shaping representations in these regions are unclear. To address this issue, we must elucidate how perceptual features shape representations of the environment. Here, we explore how the weighting of different visual features affects neural representations of objects and scenes, focusing on the scene-selective parahippocampal place area (PPA), but additionally including the retrosplenial complex (RSC), occipital place area (OPA), lateral occipital (LO) area, fusiform face area (FFA) and occipital face area (OFA)...

A novel illite@carbon (I@C) nanocomposite adsorbent has been synthesized via a facile hydrothermal carbonization process (HTC) using glucose as carbonaceous source and illite as the carrier. The morphology, microstructure and surface properties of the prepared nanocomposite adsorbent were analyzed by FESEM, TGA, XRD, FT-IR and Zeta potential measurements. Batch experiments were carried out on the adsorption of Cr(VI) to determine the adsorption properties of the composite. The adsorption of Cr(VI) onto the I@C nanocomposite was well described by the pseudo-second-order kinetic model and Langmuir isotherm...

Na-rich birnessite (NRB) was synthesized by a simple synthesis method and used as a high-efficiency adsorbent for the removal of ammonium ion (NH4(+)) from aqueous solution. In order to demonstrate the adsorption performance of the synthesized material, the effects of contact time, pH, initial ammonium ion concentration, and temperature were investigated. Adsorption kinetics showed that the adsorption behavior followed the pseudo second-order kinetic model. The equilibrium adsorption data were fitted to Langmuir and Freundlich adsorption models and the model parameters were evaluated...
