Millions of barrels of crude oil gushed freely from these wells, creating oil lakes in low-lying areas of the desert. Lakes were formed at more than 500 different locations, covering a total area initially estimated at 49 km. While the Kuwait Oil Company (KOC) has recovered 22.5 million barrels of the spilled crude; the remaining amount, is considered unrecoverable by standard methods. An estim...

Glutamate transporters are involved in neural differentiation, neuronal survival, and synaptic transmission. In the present study, we examined glutamate transporter 1 (GLT1) expression in the neonatal somatosensory cortex of C57BL/6 mice, and pursued its role in somatosensory development by comparing barrel development between GLT1 knock-out and control mice. During the first few neonatal days,...

Long-term whisker removal alters the balance of excitation and inhibition in rodent barrel cortex, yet little is known about the contributions of individual cells and synapses in this process. We studied synaptic inhibition in four major types of neurons in live tangential slices that isolate layer 4 in the posteromedial barrel subfield. Voltage-clamp recordings of layer 4 neurons reveal that f...

Layer IV of rodent primary somatosensory cortex is characterized by an array of whisker-related groups of neurons, known as "barrels." Neurons within each barrel respond best to a particular whisker on the contralateral face, and, on deflection of adjacent whiskers, display relatively weak excitation followed by strong inhibition. A prominent hypothesis for the processing of vibrissal informati...

The evolution of almost 40 oak-related volatile compounds and the sensorial characteristics of red wines from four Spanish denominations of origin (DOs) (Bierzo, Toro, Ribera de Duero, and Rioja) during aging in barrels made of Rebollo oak wood, Quercus pyrenaica, were studied and compared to the same wines aged in American and French oak barrels. Each oak wood added unique and special characte...

Cholinergic muscarinic receptor binding and acetylcholinesterase (AChE) histochemistry were studied in the barrel cortex of adult, vibrissae deprived and vibrissae denervated mice. In the control barrel field muscarinic receptors labeled with [3H]quinuclidinyl benzilate ([3H]QNB) showed a higher density in the granular cortex and a higher accumulation of label in the barrels. AChE staining reve...

The hypothesis that functional groups of neurons in whisker barrels are linked to a modular organization of cortical vessels was tested. Endovascular casts demonstrated cortical capillary networks resembling the whisker barrel pattern that were fed from the middle cerebral artery. In histological sections, dense capillaries apparently were confined to single barrels and were supplied by one or ...

Spatio-temporal processing of whisker information was analysed in vivo for single neurons in D2 barrel columns of S1 cortex in Tg8 mutant mice, which lack barrels. Findings were compared with normal C3H mice of the same genetic background. The topographical organization of functional columns was similar in Tg8 and normal mice. Response magnitudes (RMs) to D2 principal whisker deflections in D2 ...

The purpose of this work is to evaluate the wine spirit aged by an alternative process (staves combined with different micro-oxygenation levels) and its comparison traditional (wooden barrels). This evaluation was made analyzing volatile compounds sensory profile spirits during 365 days ageing. findings confirmed role played oxygen in spirits. Samples ageing modalities were well distinguished f...
