Herein, self-supported hierarchical AuPd alloyed interconnected nanowire networks (AuPd NCNs) were fabricated by a one-pot co-reduction method. Theophylline was acted as the capping and structure-directing agents. The product was mainly characterized by a series of techniques such as transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The hierarchical nanostructures had the enlarged electrochemically active surface area (EASA), and the enhanced catalytic activity toward formic acid oxidation reaction (FAOR) and strengthened poisoning tolerance for poisoning CO-like intermediates by cyclic voltammetry and chronoamperometry, which outperformed commercial Pd black catalyst...

Recently, ZATT (also known as ZNF451 or Zpf451) was reported by Schellenberg et al. to aid the removal of Topoisomerase II cleavage complexes by stimulating the phosphodiesterase activity of Tyrosyl DNA Phosphodiesterase 2. Although the full implication of this discovery is unknown, it will help us understand how cells respond to topoisomerase-induced genome damage and chemotherapeutic topoisomerase 'poisons'.

Populations of three resident Gyps species (Indian white-backed vulture Gyps bengalensis, Indian vulture Gyps indicus, and Slender-billed vulture Gyps tenuirostris) in India have decreased by more than 90% since mid 1990s, and they continue to decline. Experimental studies showed the mortality of vultures to be due to renal failure caused by diclofenac, a nonsteroidal anti-inflammatory drug. India, Pakistan, and Nepal banned the veterinary usage of diclofenac in 2006 to prevent further decline in vulture population...

Objectives: Clinical studies to reduce the side effects of tramadol, such as seizure, are necessary. Owing to the high prevalence of tramadol consumption and subsequent complications that result from seizures, the aim of the present study was to find a relationship between clonus and prediction of seizure outcome in patients with tramadol overdose. This can be used to determine the need for essential actions if a significant indicator of preventive medical measures is observed. Methods: In this case-control study, three groups of patients poisoned with tramadol and with marked ankle clonus were evaluated...

Botulinum neurotoxins (BoNTs) are highly potent toxins that cleave neuronal SNARE proteins required for neurotransmission, causing flaccid paralysis and death by asphyxiation. Currently, there are no clinical treatments to delay or reverse BoNT-induced blockade of neuromuscular transmission. While aminopyridines have demonstrated varying efficacy in transiently reducing paralysis following BoNT poisoning, the precise mechanisms by which aminopyridines symptomatically treat botulism are not understood. Here we found that activity-dependent potentiation of presynaptic voltage-gated calcium channels (VGCCs) underlies 3,4-diaminopyridine (3,4-DAP)-mediated rescue of neurotransmission in central nervous system synapses and mouse diaphragm neuromuscular junctions fully intoxicated by BoNT serotype A...

Biogas from biological treatments and from the waste degradation in landfills generally contains a wide range of trace impurities (e.g., sulphur compounds, siloxanes, halogens, tar compounds, etc.). This paper describes an experimental analysis performed with SOFC single cells fed by a synthetic gas polluted by H2S, HCl, D4 and a mixture of H2S + C2Cl4. The aim is to detect the threshold tolerance limit on different cell performance parameters. Results show how: hydrogen sulphide has a strong impact on the polarization losses due to the nickel sulphide formation on the electrode that causes a mass transfer resistance...

BACKGROUND: A recent Cochrane review of randomised trials identified a lack of evidence for interventions provided to drug-using offenders. We use routine data to address whether contact with treatment services reduces heroin users' likelihood of a future acquisitive offence or drug-related poisoning (DRP) death. METHODS: Heroin-users were identified from probation assessments and linked to drug-treatment, mortality and offending records. The study cohort was selected to ensure that the subject was not: in prison, in treatment or had recently left treatment...

Paraquat (PQ) as a kind of sterile and herbicides, has effects of contact-kill and systemic action, which can be absorbed quickly by green plants and make them wither and die. Therefore, it is widely used in the agricultural production and occupies a large part in our country's pesticide market. PQ poisoning has become one of the most common pesticide poisoning in our country. PQ can be passivated when combining with soil, but it has great toxicity for human. There are still no specific antidotes for PQ poisoning at home and abroad, and the death rate of PQ oral poisoning is up to 95%...

Delayed encephalopathy after acute carbon monoxide (CO) poisoning (DEACMP) is the most severe and clinically intractable complication that occurs following acute carbon monoxide poisoning. Unfortunately, the mechanism of DEACMP is still vague. Growing evidence indicates that delayed cerebral damage following CO poisoning is related to oxidative stress, abnormal neuro-inflammation, apoptosis and immune-mediated injury. Our recent report indicated that methylene blue (MB) may be a promising therapeutic agent in the prevention of neuronal cell death and cognitive deficits following transient global cerebral ischaemia (GCI)...
