El Memorial de Barcelona a Archer Milton Huntington, el fundador de la Hispanic Society of America, y a su esposa, la escultora, Anna Hyatt Huntington.

Barcelona en 1954 se anticipo a todos los homenajes, dedicando a Archer Milton Huntington (New York, 1870- Bathel, Connecticut, 1955) un monumento en reconocimiento a su excepcional figura como coleccionista e hispanófilo y también a su esposa, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973), excelente escultora que generosamente secundo los propósitos filo hispanos de su consorte. De esta manera Barcelona quería dejar constancia de su devoción y tributo a este reconocido coleccionista y filántropo americano que ayudo a vencer el llamado "Paradigma Prescott", historiador que había defendido las tesis sobre la leyenda negra española. A la vez que se reconocía que Archer M. Huntington ocupaba un lugar preeminente en la línea del hispanismo americano conjuntamente con los nombres de George Ticknor (1791 -1871), Washington Irving (1783-1859) y Henry Longfellow (1807-1882).

The Monument Erected in Barcelona in 1954 in Honor of Archer Milton Huntington, the Founder of The Hispanic Society of America, and His Wife, Anna Hyatt Huntington, the Eminent Sculptress.

It was in 1954 that Barcelona became the first city to pay tribute to Archer Milton Huntington (New York, 1870 - Bathel, Connecticut, 1955), by erecting a monument to the memory of this outstanding collector and Hispanist, and to hiswife, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973). An excellent sculptor, Anna Hyatt Huntington was also unstinting in her support of her husband¿s Hispanic interest. The monument was Barcelona's way of recognizing and paying tribute to this greatly respected American collector and philanthropist. Huntington played a major role in refuting "Prescott's Paradigm", named after the historian whose work on Spain did much to further the Black Legend.3 Moreover, Huntington occupied an important place in American Hispanic Studies, along with such other outstanding names as George Ticknor (Boston, 1791 - 1871), Washington Irving (New York, 1783 - 1859) and Henry Longfellow (1807 - 1882).

Hindleg muscle energy and substrate balances in cold-exposed rats

Rats chronically cannulated in the carotid artery and the muscular branch of the femoral vein were subjected to a cold (4 °C) environment for up to 2 h. The changes in blood flow (measured with 46Sc microspheres) and arterio-venous differences in the concentrations of glucose, lactate, triacylglycerols and amino acids allowed the estimation of substrate (and energy) balances across the hindleg. Mean glucose uptake was 0.28mmol min21, mean lactate release was 0.33mmol min21 and the free fatty acid basal release of 0.31mmol min21 was practically zero upon exposure to the cold; the initial uptake of triacylglycerols gave place to a massive release following exposure. The measurement of PO·, PCO· and pH also allowed the estimation of oxygen, CO2 and bicarbonate balances and respiratory quotient changes across the hindleg. The contribution of amino acids to the energy balance of the hindleg was assumed to be low. These data were used to determine the sources of energy used to maintain muscle shivering with time. Three distinct phases were observed in hindleg substrate utilization. (1) The onset of shivering, with the use of glucose/glycogen and an increase in lactate efflux. Lipid oxidation was practically zero (respiratory quotient near 1), but the uptake of triacylglycerols from the blood remained unchanged. (2) A substrate-energy shift, with drastically decreased use of glucose/glycogen, and of lactate efflux; utilization of triacylglycerol as practically the sole source of energy (respiratory quotient approximately 0.7); decreasing uptake of triacylglycerol and increased tissue lipid mobilization. (3) The onset of a new heat-homeostasis setting for prolonged cold-exposure, with maintenance of muscle energy and heat production based on triacylglycerol utilization and efflux from the hindleg (muscle plus skin and subcutaneous adipose masses) contributing energy to help sustain heat production by the core organs and surrounding brown adipose tissue.

Rat insulin turnover in vivo

Zucker lean and obese rats were injected under pentobarbital anesthesia with 125I-labeled insulin; at timed intervals from 30 to 120 sec, blood samples were extracted and used for the estimation of insulin levels by RIA. A group of rats from each series was maintained under a constant infusion of noradrenaline. For each insulin determination, a duplicate blood sample containing the same amount of insulin as that used in the RIA, but without the radioactive label, was used as a blank for insulin measurement. The radioactivity in these tubes was then used for the measurement of insulin label per ml blood. From plasma label decay curves and insulin concentrations, the insulin pool size, half-life, and rate of degradation were calculated. Obese rats had higher insulin levels (2.43 nM) and showed less effect of noradrenaline than their lean counterparts, in which insulin distribution volume shrank with noradrenaline treatment. The half-life of plasma insulin was similar in all groups (range, 226-314 sec). Pool size and overall degradation rates were higher in obese (198 femtokatals) than in lean rats (28 femtokatals). It is postulated that obese rats synthesize and cleave much more insulin than lean controls despite their higher circulating levels of insulin.

Unusual association of diseases/symptoms: Encephalitis with herpes simplex-2 in the cerebrospinal fluid and anti-RI (ANNA-2) antibodies: an infectious or a paraneoplastic syndrome?

We report on a 70-year-old woman with partial complex status epilepticus who was initially diagnosed with herpes simplex-2 (HSV-2) encephalitis, based on brain magnetic resonance imaging (MRI) findings, cerebrospinal fluid (CSF) lymphocytic pleocytosis and HSV-2 DNA detection by polymerase chain reaction (PCR) in the CSF, but without improvement on intravenous acyclovir. Anti-Ri antibodies were positive and computed tomography (CT) investigations revealed a small cell carcinoma at biopsy suggesting paraneoplastic encephalitis. The outcome was unfavourable and the autopsy showed typical features of paraneoplastic encephalitis but no evidence of viral inclusions. This case report is interesting because: (1) it is the first report of an autopsy proven paraneoplastic widespread encephalitis with anti-Ri antibodies; (2) despite a positive HSV-2 PCR in the CSF, there was no sign of herpetic infections of the nervous system; and (3) it illustrates the fact that if paraneoplastic antibodies are usually good markers of the underlying tumour, they are not always predictive of neurological deficits.
