Interstitial cells of Cajal and enteric nervous system in gastrointestinal and neurological pathology. Relation to oxidative stress

The enteric nervous system (ENS) is organized into two plexuses—submucosal and myenteric—which regulate smooth muscle contraction, secretion, and blood flow along the gastrointestinal tract under the influence of the rest of the autonomic nervous system (ANS). Interstitial cells of Cajal (ICCs) are mainly located in the submucosa between the two muscle layers and at the intramuscular level. They communicate with neurons of the enteric nerve plexuses and smooth muscle fibers and generate slow waves that contribute to the control of gastrointestinal motility. They are also involved in enteric neurotransmission and exhibit mechanoreceptor activity. A close relationship appears to exist between oxidative stress and gastrointestinal diseases, in which ICCs can play a prominent role. Thus, gastrointestinal motility disorders in patients with neurological diseases may have a common ENS and central nervous system (CNS) nexus. In fact, the deleterious effects of free radicals could affect the fine interactions between ICCs and the ENS, as well as between the ENS and the CNS. In this review, we discuss possible disturbances in enteric neurotransmission and ICC function that may cause anomalous motility in the gut

Influencia del tamaño, la variedad y la proporción de sexos en la producción de huevos de tilapia (Oreochromis spp) en un sistema tropical intensivo al aire libre

The effect of the variety, size of the females and sex ratio in the production of eggs of Chitralada (CH: Oreochromis niloticus) and Taiwanese red (TR: O. mossambicus x O. niloticus) in outdoor concrete tanks were evaluated in a fish production unit located in the Andean foothills of the state of Trujillo, Venezuela. A 2x2x3 factorial arrangement design was used: two varieties (CH and TR), two sizes (large and small) and three female male proportions (1:1, 2:1 and 3:1). CH females produced greater volume and mass of eggs, spawned 2.4-fold more and were more fertile than TR (p<0.01). Large tilapia had 1.6-fold fewer spawning (p<0.05) and produced fewer eggs per 100 females than small ones (p<0.01). In general, the F:M ratio did not affect the reproductive variables. The small females of both varieties had a higher number of spawning than the large ones, and the large CH tilapia spawned 3.9 times more than the TR of the same size (p<0.01), while in the small ones this difference was only 1.7 times (p<0.05). The large CH tilapias were reproductively more efficient than the females of the same category of the TR variety. In conclusion, the CH tilapia and the smaller size and weight females were reproductively more efficient than those of the TR variety and the larger ones. Regardless of the variety, the reproductive activity was not affected by the proportions between females and males.Se evaluó el efecto de la variedad, tamaño de las hembras y relación hembra macho en la producción de huevos de tilapias Chitralada (CH: Oreochromis niloticus) y Taiwanesa roja (TR: O. mossambicus x O. niloticus), en tanques de concreto al aire libre, en una unidad de producción piscícola localizada en el Piedemonte Andino del estado Trujillo, Venezuela. Se utilizó un diseño en arreglo factorial 2x2x3: dos variedades (CH y TR), dos tamaños (grades y pequeñas) y tres proporciones hembra macho (1:1, 2:1 y 3:1). Las hembras CH produjeron mayor volumen y masa de huevos, desovaron 2.4 veces más y fueron más fecundas que las TR (p<0.01). Las tilapias grandes tuvieron 1.6 veces menos desoves (p<0.05) y produjeron menos huevos por cada 100 hembras que las pequeñas (p<0.01). En general, la relación H:M no afectó las variables reproductivas. Las hembras pequeñas de ambas variedades tuvieron un mayor número de desoves que las grandes, y las tilapias CH grandes desovaron 3.9 veces más que las TR del mismo tamaño (p<0.01), mientras que en las pequeñas esta diferencia fue de tan solo 1.7 veces (p<0.05). Las tilapias CH grandes fueron reproductivamente más eficientes que las hembras de la misma categoría de la variedad TR. En conclusión, las tilapias CH y las hembras de menor talla y peso fueron reproductivamente más eficientes que las de la variedad TR y las de mayor tamaño. Independientemente de la variedad, la actividad reproductiva no se vio afectada por las proporciones entre hembras y machos

Bladder cancer index: cross-cultural adaptation into Spanish and psychometric evaluation

BACKGROUND: The Bladder Cancer Index (BCI) is so far the only instrument applicable across all bladder cancer patients, independent of tumor infiltration or treatment applied. We developed a Spanish version of the BCI, and assessed its acceptability and metric properties. METHODS: For the adaptation into Spanish we used the forward and back-translation method, expert panels, and cognitive debriefing patient interviews. For the assessment of metric properties we used data from 197 bladder cancer patients from a multi-center prospective study. The Spanish BCI and the SF-36 Health Survey were self-administered before and 12 months after treatment. Reliability was estimated by Cronbach's alpha. Construct validity was assessed through the multi-trait multi-method matrix. The magnitude of change was quantified by effect sizes to assess responsiveness. RESULTS: Reliability coefficients ranged 0.75-0.97. The validity analysis confirmed moderate associations between the BCI function and bother subscales for urinary (r = 0.61) and bowel (r = 0.53) domains; conceptual independence among all BCI domains (r ≤ 0.3); and low correlation coefficients with the SF-36 scores, ranging 0.14-0.48. Among patients reporting global improvement at follow-up, pre-post treatment changes were statistically significant for the urinary domain and urinary bother subscale, with effect sizes of 0.38 and 0.53. CONCLUSIONS: The Spanish BCI is well accepted, reliable, valid, responsive, and similar in performance compared to the original instrument. These findings support its use, both in Spanish and international studies, as a valuable and comprehensive tool for assessing quality of life across a wide range of bladder cancer patients
