Three-dimensional photoactive self-standing porous materials have been synthesized through the integration of soft chemistry and colloids (emulsions, lyotrope mesophases, and P25 titania nanoparticles). Final multiscale porous ceramics bear 700-1000 m g of micromesoporosity depending on the P25 nanoparticle contents. The applied thermal treatment does not affect the P25 anatase/rutile allotropic phase ratio.

The last few years have seen the proliferation of anaerobic digestion plants to produce biomethane. Oxygen (O) traces added to biogas during the desulfurization process are co-injected in the gas network and can be stored in Underground Gas Storage (UGS). However, there are no data available for the undesirable effects of O on these anoxic environments, especially on deep aquifers.

Organic clathrates formed by hydroquinone (HQ) and gases such as CO and CH are solid supramolecular host-guest compounds in which the gaseous guest molecules are encaged in a host framework of HQ molecules. Not only are these inclusion compounds fascinating scientific curiosities but they can also be used in practical applications such as gas separation. However, the development and future use of clathrate-based processes will largely depend on the effectiveness of the reactive materials used.

Article Synopsis
  • Understanding biomass production in secondary forests after slash-and-burn cultivation is crucial for evaluating the resilience of these systems and their ecosystem services.
  • The study analyzed 6,452 trees in fallow plots, finding that aboveground biomass (AGB) is influenced by fallow age, remnant tree proportion, and previous cultivation cycles, which negatively impact biomass productivity.
  • Results indicate that increased management intensity leads to a decline in the ability of slash-and-burn systems to offer essential ecosystem functions like carbon sequestration.

Assessment of the intravascular volume status of patients is one of the most challenging tasks for the intensive care clinician. It is also one of the most important skills in intensive care management as both hypervolaemia and hypovolaemia lead to increased morbidity and mortality. The assessment of hypovolaemic patients is aided by several clinical signs, laboratory investigations, and a multitude of haemodynamic monitoring systems.

The gastrointestinal tract comprises diverse functions. Despite recent developments in technology and science, there is no single and universal tool to monitor GI function in intensive care unit (ICU) patients. Clinical evaluation is complex and has a low sensitivity to diagnose pathological processes in the abdomen.

Gastrointestinal (GI) problems after surgery are common and are not limited to patients undergoing abdominal surgery. GI function is complicated to monitor and is not included in organ dysfunction scores widely used in the ICUs. In most cases, it recovers after surgery, if systemic and local inflammation and perfusion improve, gut oedema resolves, and analgosedation is reduced.

In this report, the development of conventional, mass-printing strategies into high-resolution, alternative patterning techniques is reviewed with the focus on large-area patterning of flexible thin-film transistors (TFTs) for display applications. In the first part, conventional and digital printing techniques are introduced and categorized as far as their development is relevant for this application area. The limitations of conventional printing guides the reader to the second part of the progress report: alternative-lithographic patterning on low-cost flexible foils for the fabrication of flexible TFTs.

In this paper, a thermal imprint technique, double-layer nanoimprint lithography (dlNIL), is introduced, allowing complete filling of features in the dimensional range of submicrometer to millimeter. The imprinting and filling quality of dlNIL was studied on Si substrates as a model system and compared to results obtained with regular NIL (NIL) and reverse NIL (rNIL). Wavy foils were imprinted with NIL, rNIL and dlNIL and the patterning results compared and discussed.

Objective: To analyse and compare the concentration of plasminogen activator (PA), urokinase-type PA (uPA), tissue-type PA (tPA), PA inhibitor (PAI)-1 and PAI-2, and the complexes uPA-PAI-1 and tPA-PAI-1 and calculated uPA and tPA uncomplexed with PAI-1 ('free') in urothelial cell carcinoma and matched benign urothelium, and in renal cell carcinoma (RCC) and matched benign renal tissue.

Patients And Methods: Tissue samples were obtained during cystectomy (33 patients) and nephrectomy (55), and specific enzyme-linked immunosorbent assays were used to assess the PA components in extracts of these tissues.

Results: Tissue levels of uPA-PAI-1 and tPA-PAI-1, but also PAI-1 itself, were greater in tumorous bladder and kidney tissue than in matched normal tissue (by 1.

Background: The common event in transmissible spongiform encephalopathies (TSEs) or prion diseases is the conversion of host-encoded protease sensitive cellular prion protein (PrPC) into strain dependent isoforms of scrapie associated protease resistant isoform (PrPSc) of prion protein (PrP). These processes are determined by similarities as well as strain dependent variations in the PrP structure. Selective self-interaction between PrP molecules is the most probable basis for initiation of these processes, potentially influenced by chaperone molecules, however the mechanisms behind these processes are far from understood.

Objectives: High-risk human papilloma virus (HPV) types stimulate degradation and deactivation of protein associated with the p53 tumour suppressor gene via the ubiquitin-dependent pathway. For a long time, changes of the p53 tumour suppressor gene have been correlated with poor clinical outcome in patients with superficial bladder cancer. We aimed to study the association between presence of (high-risk) HPV DNA, p53 status, and clinical outcome in bladder cancer patients.

During the epidemic of foot-and-mouth disease (FMD) in The Netherlands in 2001, a sheep farm was identified that had been subclinically infected with the disease. The FMD virus genome was detected in 12 of 16 probang samples collected from the sheep and the virus was isolated from four of these samples. Linear defects were observed, 1 to 3 cm from the coronary band, in the hooves of several of the sheep.

Introduction And Objective: Several studies have shown that rigid fluorescence cystoscopy (RFC) with hexaminolevulinate (HAL) is superior to standard rigid white light (RWLC) cystoscopy in diagnosing bladder tumours, with a clinically relevant impact on the patient's management. These studies, however, have been done with rigid cystoscopes. We carried out a study to evaluate whether the technique of fluorescence cystoscopy with HAL was also feasible with a specially designed flexible fluorescence cystoscope (FFC).
