ABSTRACT: Acclimatization is the final phase of banana plantlet production by micropropagation. In this phase, plantlets are grown in a protected environment with high demand for water, fertilizer and labor, until reaching standard size quality required marketing. The aim study was to evaluate possibility reducing these costs duration acclimatization using hydroponic cultivation technique as co...

Epidemiological studies have shown an association between consumption of alcoholic beverages and carcinoma of the large bowel, but studies in experimental models of colonic carcinogenesis have yielded conflicting results. We assessed the effects on azoxymethane-induced colonic carcinogenesis of both timing of chronic dietary ethanol consumption relative to carcinogen administration and quantity...

23 Chronic living at altitudes ~2500m causes consistent hematological acclimatization in most, but 24 not all, groups of athletes; however, responses of erythropoietin (EPO) and red cell mass to a 25 given altitude show substantial individual variability. We hypothesized that athletes living at 26 higher altitudes would experience greater improvements in sea level performance, secondary to 27 g...

Acclimatization to hypoxia requires time to complete the adaptation mechanisms that influence oxygen (O(2)) transport and O(2) utilization. Although decreasing hemoglobin (Hb) O(2) affinity would favor the release of O(2) to the tissues, increasing Hb O(2) affinity would augment arterial O(2) saturation during hypoxia. This study was designed to test the hypothesis that pharmacologically increa...

Recent studies have demonstrated that brief daily IAE (intermittent altitude exposure) was equally as effective as continuous altitude residence in inducing physiological adaptations consistent with altitude acclimatization. Although the positive benefits of IAE have been clearly defined, the potential negative consequences of IAE on health, specifically the immune system, remain undefined. The...

Avian intrapulmonary chemoreceptors (IPC) are vagal sensory neurons that participate in the control of breathing. IPC action potential frequency is inversely proportional to [Formula: see text], but it is unclear whether low [Formula: see text] or high pH is the immediate stimulus for signal transduction in IPC. To address this question, comparisons were made between single cell neural response...

BACKGROUND benefit and acclimatization. AIM to characterize the short-term benefits presented by adults, recent users of hearing aids, through objective (functional gain) and subjective (self-evaluation questionnaires) procedures. The possible occurrence of the phenomenon of acclimatization was also investigated based on the analysis of the speech recognition percent index (SRPI) before the f...
