Abstract
Recent data have shown anti-inflammatory effects for trans-resveratrol (RSV) and rosmarinic acid (RA) in various immune-competent cell models through reduction of lipopolysaccharide (LPS)-induced interleukin 6 (IL-6) release. Because both compounds have been reported to taste bitter, we hypothesized an involvement of human bitter taste sensing receptors (TAS2Rs) on IL-6 release in LPS-treated human gingival fibroblasts (HGF-1). First, the bitter taste intensity of RSV and RA was compared in a sensory trial with 10 untrained panelists, of whom 90% rated a 50 ppm of RSV in water solution more bitter than 50 ppm of RA. A mean 19 ± 6% reduction of the RSV-induced bitter taste intensity was achieved by co-administration of 50 ppm of the bitter-masking, TAS2R43 antagonist homoeriodictyol (HED). Mechanistic experiments in a stably CRISPR-Cas9-edited TAS2R43ko gastric cell model revealed involvement of TAS2R43 in the HED-evoked effect on RSV-induced proton secretion, whereas the cellular response to RSV did not depend upon TAS2R43. Next, the IL-6 modulatory effect of 100 μM RSV was studied in LPS-treated immune-competent HGF-1 cells. After 6 h of treatment, RSV reduced the LPS-induced IL-6 gene expression and protein release by -46.2 ± 12.7 and -73.9 ± 2.99%, respectively. This RSV-evoked effect was abolished by co-administration of HED. Because real-time quantitative polymerase chain reaction analyses revealed a regulation of TAS2R50 in RSV with or without HED-treated HGF-1 cells, an siRNA knockdown approach of TAS2R50 was applied to verify TAS2R50 involvement in the RSV-induced reduction of the LPS-evoked IL-6 release in HGT-1 cells.

Abstract
Naturally occurring cinnamon compounds such as cinnamaldehyde (CAL) and structurally related constituents have been associated with antiobesity activities, although studies regarding the impact on intestinal fatty acid uptake are scarce. Here, we demonstrate the effects of CAL and structural analogues cinnamyl alcohol (CALC), cinnamic acid (CAC), and cinnamyl isobutyrate on mechanisms regulating intestinal fatty acid uptake in differentiated Caco-2 cells. CAL, CALC, and CAC (3000 μM) were found to decrease fatty acid uptake by 58.0 ± 8.83, 19.4 ± 8.98, and 21.9 ± 6.55%, respectively. While CAL and CALC at a concentration of 300 μM increased serotonin release 14.9 ± 3.00- and 2.72 ± 0.69-fold, respectively, serotonin alone showed no effect on fatty acid uptake. However, CAL revealed transient receptor potential channel A1-dependency in the decrease of fatty acid uptake, as well as in CAL-induced serotonin release. Overall, CAL was identified as the most potent of the cinnamon constituents tested.

Abstract
A microcomputer-based system for carrying out learned helplessness experiments is described. The hardware is inexpensive and easily available. The program is written in BASIC and must be executed in the compiled form in order to keep up with real-time events. It contains an algorithm for calculating inter-trial intervals and allows the experimentor to freely select experimental conditions such as duration of shock, number of trials, etc. The task that the rat is required to do to stop the shock is also selectable, thus giving the experimentor the opportunity to maximize behavioral differences between escapable and inescapable rats while these differences are being induced. Experimental data on 12 rats that went through this automated protocol are analyzed and discussed.

Abstract
Ten patients treated with vincristine were submitted for electrophysiological examination. It was investigated the number of motor units within the thenar muscle following a technique described previously (Sica et al. - 1974); motor and sensitive conduction velocities as well as motor distal latencies in the median nerve were studied following conventional techniques. The behaviour of the evoked muscle potential with repetitive supramaximal stimulation over the median nerve was also investigated. The findings were compared with control groups. The estimated number of motor units was disminished in eight of ten patients and the average number was significantly different from the control group (control 318 +/- 71 UM; patients 174 +/- 84 UM; P less than 0.001). The potential amplitudes in most of the surviving units were reduced, others remaining within the normal range. This makes apparent that the peripherical nervous system fails to compensate adequately and, furthermore, a loss of individual muscle fibres occurs within some individual units. The conduction velocities of the fastest conducting motor nerve fibres were reduced and motor distal latencies prolongued (Table 1). Maximal impulse conduction velocities were measured in sensory fibres. In 5 of 7 subjets investigated the values laied just beyond the lower limit of the normal range. The amplitude of the sensory orthodromic evoked potential in the median nerve at the wrist was disminished almost in the whole group. The decremental muscle response to repetitive nerve stimulation, can be interpreted as the result of the damage at the neural apparatus at the motor end plate; it was observed in 57% of the patients. In summary, evidences have been registered showing that the nervous supply to the muscle is affected in patients treated with vincristine; the motor unit behaviour under this conditions is discussed.

Abstract
Diez pacientes afectados por diversas patologías que requerían tratamiento crónico con Vincristina, fueron sometidos a estudios electrofisiológicos en los que se valoró: el número de unidades motoras (UM) funcionantes en los músculos de la eminencia tenar, los valores de los incrementos medios de UM, velocidad de conducción motora y su latencia residual en el nervio mediano, la velocidad de conducción sensitiva del mismo nervio y el estado de la transmisión neuromuscular. Los valores obtenidos fueron comparados con grupos controles. Los resultados mostraron disminución del número de UM; las UM remanentes presentaron amplitud reducida junto a otras cuyo tamaño no superaba el del grupo control, hecho que sugiere la incapacidad de lograr una reinervación adecuada. Las velocidades de conducción motora y sensitiva mostraron valores diminuídos, con mayor compromiso en los segmentos distales. Junto a estos datos se halló respuesta miasteniforme al estímulo repetitivo. Todos estos resultados permiten postular la existencia de un compromiso de la unidad motora, abarcando todos sus segmentos, en pacientes intoxicados con Vincristina.
