Macrophages play impor tant roles in inflammation and host defense against bacterial infection. T h e metabolites o f arachidonic acid (20:4) 1 are impor tant modulators o f these responses (1). When macrophages interact with stimuli such as an immune complex or a bacter ium, phospholipases are activated and 20:4 is l iberated f rom plasma mem b ran e phospholipids. T h e free 20:4 is then quan...
The Impact of Alcohol Consumption on Occupational Attainment in England In this study we provide evidence on the effect of alcohol consumption on occupational attainment in England. To do this we use samples of employees from the Health Survey for England between 1992 and 1996. We find that due to the endogenous nature of alcohol consumption, OLS estimates may provide a biased picture of the im...

This study aimed to evaluate the repellent effect of tea tree (Melaleuca alternifolia) and andiroba (Carapa guianensis) essential oils on two species of flies (Haemotobia irritans and Chrysomya megacephala). For the in vitro studies, free-living adult flies were captured and reared in the laboratory. To verify the repellency effect, an apparatus was constructed where H. irritans and C. megaceph...
Abstract The heat capacity of bismuth cobalt oxides doped by neodymium and holmium was measured for the first time differential scanning calorimetry in temperature range 319-1000 K.
We discuss a method for scaling a neutral-atom Rydberg gate quantum processor to a large number of qubits. Limits are derived showing that the number of qubits that can be directly connected by entangling gates with errors at the 10−3 level using long-range Rydberg interactions between sites in an optical lattice, without mechanical motion or swap chains, is about 500 in two dimensions and 7500...
In the dynamic nuclear polarization process, microwave irradiation facilitates exchange of polarization from a radical's unpaired electron to nuclear spins at cryogenic temperatures, increasing polarization by >10,000. Doping samples with Gd(3+) ions further increases the achievable solid-state polarization. However, on dissolution, paramagnetic lanthanide metals can be potent relaxation agents...
We take another look at two compounds which have been discussed as possible realizations of ‘‘spin ice,’’ namely holmium titanate and dysprosium titanate. As we have earlier observed, holmium titanate does not display icelike behavior at low temperatures because the long-ranged dipolar interactions between spins are strong compared to the nearest-neighbor interactions. We show, exactly, that th...
A nanoparticle (NP) doping technique was developed for fabricating erbium (Er)- and holmium (Ho)-doped silica-based optical fibers for high energy lasers. Slope efficiencies in excess of 74% were realized for Er NP doping in a single mode fiber based master oscillator power amplifier (MOPA) and 53% with multi-Watt-level output in a resonantly cladding-pumped power oscillator laser configuration...
BACKGROUND In 1996, Holmium laser enucleation of the prostate was introduced and has been shown to be safe and highly effective. CASE PRESENTATION We report a case of a rare complication that resulted in intra-abdominal compartment syndrome with prolonged intubation and intensive care, involving an 74-year-old male after holmium laser enucleation of prostate, with a massive irrigant fluid lea...
