AIMS: H2O2 is produced by all eukaryotic cells under physiological and pathological conditions. Due to its enormous relevance for cell signaling at low concentrations and anti-pathogenic function at high concentrations, precise quantification of extracellular local H2O2 concentrations ([H2O2]) originating from single cells is required. RESULTS: Using a scanning electrochemical microscope and bare platinum disk ultramicroelectrodes, we established sensitive long term measurements of extracellular [H2O2] kinetics originating from single primary human monocytes ex vivo...

BACKGROUND: The optimal time to save a person who has had a sudden cardiac arrest is within the first few minutes of the incident. Early compression and early defibrillation should be performed at this time. Timeliness is the key to successful CPR; as such, Prof. He proposed the "platinum 10 min" system to study early CPR issues. This paper systematically evaluates the success rates of heartbeat restoration within the "platinum 10 min" among patients suffering from sudden cardiac arrest...

Complete blood cell counts (CBCs) are one of the most commonly ordered and informative blood tests in hospitals. The results from a CBC, which typically include white blood cell (WBC) counts with differentials, red blood cell (RBC) counts, platelet counts and hemoglobin measurements, can have implications for the diagnosis and screening of hundreds of diseases and treatments. Bulky and expensive hematology analyzers are currently used as a gold standard for acquiring CBCs. For nearly all CBCs performed today, the patient must travel to either a hospital with a large laboratory or to a centralized lab testing facility...

The platinum-based anticancer drug oxaliplatin is important clinically in cancer treatment. However, the role of multidrug resistance-associated protein 2 (MRP2) in controlling oxaliplatin membrane transport, in vivo handling, toxicity and therapeutic responses is unclear. In the current study, preparations of MRP2-expressing and control membrane vesicles, containing inside-out orientated vesicles, were used to directly characterise the membrane transport of oxaliplatin-derived platinum measured by inductively coupled plasma mass spectrometry...

Highly efficient tree branch-shaped CuO photocathodes are fabricated using the hybrid microwave annealing process with a silicon susceptor within 10 minutes. The unique hierarchical, one-dimensional structure provides more facile charge transport, larger surface areas, and increased crystallinity and crystal ordering with less defects compared to irregular-shaped CuO prepared by conventional thermal annealing. As a result, the photocathode fabricated with the tree branch-shaped CuO produces an unprecedently high photocurrent density of -4...

BACKGROUND: The efficacy of the ALK inhibitor crizotinib as compared with standard chemotherapy as first-line treatment for advanced ALK-positive non-small-cell lung cancer (NSCLC) is unknown. METHODS: We conducted an open-label, phase 3 trial comparing crizotinib with chemotherapy in 343 patients with advanced ALK-positive nonsquamous NSCLC who had received no previous systemic treatment for advanced disease. Patients were randomly assigned to receive oral crizotinib at a dose of 250 mg twice daily or to receive intravenous chemotherapy (pemetrexed, 500 mg per square meter of body-surface area, plus either cisplatin, 75 mg per square meter, or carboplatin, target area under the curve of 5 to 6 mg per milliliter per minute) every 3 weeks for up to six cycles...

OBJECTIVES: Endovascular occlusion of blood vessels represents a key component of interventional therapy. While coils are most commonly used, vessel occlusion is generally not achieved immediately and may necessitate a large number of devices. It has been suggested that endovascular plugs may overcome these limitations; however, immediate and durable occlusion remains a challenge with plugs as well. This study evaluates a newly designed endovascular occlusion system (EOS) METHODS: The EOS combines a nitinol coil with an impermeable membranous cap made of expanded polytetrafluoroethylene...

OBJECTIVES: Growing, small, peripheral, pulmonary nodules in patients at high risk for lung cancer lead to requests for video-assisted thoracoscopic (VATS) resection for pathologic diagnosis. The purpose of this randomized controlled trial was to determine if preoperative localization using percutaneously placed computed tomography (CT)-guided platinum microcoils decreases the need for thoracotomy or VATS anatomic resection (segmentectomy/lobectomy) for diagnosis. METHODS: Patients with undiagnosed nodules of 15 mm or less were randomized to either no localization or preoperative microcoil localization...

Five liters of sodium hypochlorite aqueous solution (12 mass%) was poured into 300 L of liquid waste containing ammonium ion of about 1.8 mol/L in a 500 L tank in a plant area; then, two minutes later the solution exploded with a flash on March 30th, 2005. The tank cover, the fluorescent lamp and the air duct were broken by the blast wave. Thus, we have conducted 40 runs of laboratory-scale explosion tests under various conditions (solution concentrations of (NH4)2SO4 and NaClO, temperatures, Pt catalysts, pH, etc...

The effectiveness and safety of continuous glucose monitors (CGMs) is dependent on their accuracy and reliability. The objective of this study was to compare 3 CGMs in adult and pediatric subjects with type 1 diabetes under closed-loop blood-glucose (BG) control. Twenty-four subjects (12 adults) with type 1 diabetes each participated in one 48-hour closed-loop BG control experiment. Venous plasma glucose (PG) measurements obtained every 15 minutes (4657 values) were paired in time with corresponding CGM glucose (CGMG) measurements obtained from 3 CGMs (FreeStyle Navigator, Abbott Diabetes Care; G4 Platinum, Dexcom; Enlite, Medtronic) worn simultaneously by each subject...

The colorimetric cyanide sensing ability of free base porpholactone, a pyrrole-modified porphyrin in which a porphyrin β,β'-double bond was replaced by a lactone functionality, and its zinc(II), platinum(II), and gallium(III) complexes in aqueous solution are reported. Water-solubility of the parent meso-pentafluorophenyl-derivatized porphyrinoids was assured by PEGylation of the p-aryl positions using a nucleophilic aromatic substitution reaction with thiol-terminated PEG chains. A central metal-dependent sensing mechanism was revealed: While the CN(-) adds to the zinc(II) complex as an axial ligand, resulting in a minor response in its UV-vis spectrum, it undergoes a nucleophilic addition to the lactone moiety in the platinum(II) and gallium(III) complexes, leading to a much more prominent optical response...

A pharmacokinetic study was carried out in patients with unresectable colorectal liver metastases who had primarily been included in a phase II trial of intra-arterial cisplatin (DDP) plus intravenous fluorouracil. Ten patients of those accrued for the clinical study underwent the pharmacokinetic investigation upon liver progression of the disease. Four patients were treated with DDP (24 mg/m(2)) through short intra-arterial infusion (baseline study) and 4 patients received intra-arterial hyaluronidase (HY, 100 000IU) 2 minutes before DDP infusion...

BACKGROUND: Palonosetron is a potent second generation 5- hydroxytryptamine-3 selective antagonist which can be administered by either intravenous (IV) or oral routes, but subcutaneous (SC) administration of palonosetron has never been studied, even though it could have useful clinical applications. In this study, we evaluate the bioavailability of SC palonosetron. PATIENTS AND METHODS: Patients treated with platinum-based chemotherapy were randomized to receive SC or IV palonosetron, followed by the alternative route in a crossover manner, during the first two cycles of chemotherapy...

Instant and sensitive detection of pathogen at ultralow concentrations without time-consuming procedures, such as culture or amplification by PCR, offer obvious advantages. However, there is currently no general and satisfactory assay that could detect bacteria at concentrations of < 100 cfu/mL without pre-enrichment via a culture process. Compared to magnetic beads (1-5 μm in diameter) used in biological separation, magnetic nanoparticles (<10 nm in diameter) promise high performance because of the large surface/volume ratios and easy entry into cells...

BACKGROUND: Home-based care in oncology is mainly reserved for patients at the end of life. Regulations regarding home delivery of cytotoxics differ across Europe, with a notable lack of practice guidelines in most countries. This has led to a lack of data addressing the feasibility of home-based administration of cytotoxic chemotherapy. In advanced non-squamous non-small cell lung cancer, pemetrexed is approved as maintenance therapy after first-line chemotherapy. In this setting, patients have the potential to be treated long-term with maintenance therapy, which, in the absence of unacceptable toxicity, is continued until disease progression...

In a number of clinical conditions such as intoxication, bacteraemia or autoimmune diseases the removal of the disease-causing factor from blood would be the most direct cure. However, physicochemical characteristics of the target compounds limit the applicability of classical filtration and diffusion-based processes. In this work, we present a first in vivo magnetic blood purification rodent animal model and demonstrate its ability to rapidly clear toxins from blood circulation using two model toxins with stable plasma levels (lead (Pb(2+)) and digoxin)...
