Moderator Role

The Gamified Learning Theory implies that gamification does not affect learning directly but stimulates a learning-related behavior in a mediating or moderating process. A learner-related behavior can, to some extent, be predicted based on the way learners tend to perceive, understand and utilize information. These different ways of learning are known as learning tendencies. This study investigates the moderator role of learning tendencies on gamification success concerning learners' academic participation, engagement, and experience. For this, Felder-Silverman Learning Style Model is used for the identification of learners' tendencies. In our study, 69 Computer Science students were randomly assigned to one control and two treatment groups. Students in the treatment groups were assigned two different gamified courses, while the control group attended a non-gamified course. This allowed us to analyze the individual effect of each gamification design and compare and see which gamification design was more appropriate for a learner with particular tendencies. Our results indicate that gamification design positively contributes to academic participation, affects learners' engagement in gamified environments, and that students' learning tendencies moderated students' engagement.

Because of the increased concern over use of human body fluids in physiology teaching laboratories, we developed an exercise in renal function that utilizes laboratory rats. The purpose is to demonstrate the role of the kidneys in the homeostatic control of extracellular fluid volume, plasma ionic concentrations, and osmolarity. Three treatment groups are utilized: a volume-expanded (access to 1 g/100 ml sucrose) group, a volume-expanded and salt-loaded (access to 0.9 g/100 ml NaCl) group, and a volume-depleted (water-deprived) group. A normovolemic control group (access to tap water) is also included. Rats are housed individually in metabolic cages that allow accurate measurement of fluid intake and urine output. Blood samples are removed via cardiac puncture. The animals recover from this procedure and can be reutilized within 2-3 wk. When class data are pooled, clear trends are seen that demonstrate the volume-, osmo-, and ionoregulatory abilities of the kidneys.

Retinal Angiogenesis

Methylglyoxal (MG) is an intermediate of glucose metabolism and the precursor of advanced glycation end products (AGEs) found in high levels in blood or tissue of diabetic patients. MG and AGEs are thought to play a major role in the pathogenesis of diabetic retinopathy. In order to determine if zebrafish is valuable to help us understand more about retinopathy, we evaluate if MG induces abnormal vascular change and angiogenesis in zebrafish in a short incubation period. We also used an inhibitor of VEGFR (PTK787) to explore the mechanistic role of VEGF in MG-induced pathogenesis. A transgenic Tg(flk1:GFP) zebrafish line was used, and the embryos were incubated with MG solution and in combination with glucose (to mimic hyperglycemia). Retinal vascular structure visible with fluorescence signal was imaged using fluorescence microscopy. The percentage of vascular area was calculated and found elevated in the MG treatment groups than that in the control group (p<0.01) which indicated increased angiogenesis induced by MG treatment. PTK787 blocked the proangiogenic effects of MG treatment. This study suggests that MG has a potential proangiogenic effect via VEGF signaling in the retina of zebrafish embryos. Therefore, this zebrafish model may be used to study neovascular retinopathy.

The aim of the present study was to verify the effects of fish oil and a soya-based product on inflammatory markers and endothelial function measured by NO in women with the metabolic syndrome (MetS). A total of sixty-five women (mean age: 47·9 (sd9·98) years) were studied in a 90-d parallel, randomised design. A control group maintained their usual diet; the second group received 29 g/d of soyabean (kinako); the third group received 3 g/d of fish oiln-3 fatty acids; and the fourth group received fish oil (3 g/d) and kinako (29 g/d). Anthropometric, blood pressure (BP), inflammatory markers, anti-inflammatory marker (adiponectin) and NO concentrations were evaluated. In relation to the baseline values, the group that received fish oil and kinako concomitantly presented a statistically significant decrease in systolic BP (SBP;P < 0·05), whereas there was a significant decrease in diastolic BP (DBP) in the control group (P < 0·05), kinako group (P < 0·01) and fish oil group (P < 0·01) after 90 d. There was a significant increase in adiponectin (P < 0·01) and NO values (P < 0·05) after 90 d in the kinako and fish oil groups. Differences between treatment groups verified a significant decrease (P < 0·05) in DBP in the kinako group after 90 d when compared to the results obtained from the fish oil and kinako groups. In conclusion, the findings of increased serum adiponectin and NO metabolite levels after 90 d, both in the fish oil and soya groups, reinforce the importance of the influence of adiponectin and NO levels on BP decrease in patients with the MetS.

AbstractA total of twenty-four Yorkshire gilt pigs of 6–7 weeks of age were used in a 2×2 factorial experiment to determine the individual and combined effects of the inclusion of two dietary factors (cholesterol rich, 3 %β-cyclodextrin (BCD) andLactobacillus acidophiluscultures) on total cholesterol and LDL-cholesterol levels in blood serum. Pigs were assigned randomly to treatment groups (n6). Total serum cholesterol concentrations decreased after 3 weeks in all the experimental treatment groups, including diets with BCD,L.acidophilusor both. Similar trends were observed for serum LDL-cholesterol concentrations among the experimental treatments. No statistically significant differences from the control group were observed in either total serum cholesterol or LDL-cholesterol concentrations (P<0·05) for each of the individual treatment groups: BCD orL.acidophilus. However, significant differences in total serum cholesterol concentrations were observed when comparing the combined treatment group (BCD andL.acidophilus) with the control group, which consisted of a basal diet and sterile milk. The combined treatment group exhibited 17·9 % lower total serum cholesterol concentration after 3 weeks. Similar significant differences were observed when comparing the combined effect experimental group with the control group after 3 weeks. The combined treatment group exhibited 27·9 % lower serum LDL-cholesterol concentrations.

Emotional Cutoff

Bowen’s multigenerational family theory emphasizes the importance of autonomy and interdependence in individual development and focuses on the role played by the differentiation of self processes on the psychological health at the individual, dyadic, and systemic levels. Starting from these premises, the main objective of our investigation was to explore the differences, in the levels of anxiety and differentiation of self, between a control group ( n = 69) and a sample of adults seeking therapeutic services for anxiety ( n = 47). To better specify our results, in a second step, we also explored which of the differentiation of self dimensions could increase or reduce the likelihood that an individual belonged to the anxiety group or to the control group. We found that lower levels of I-position, and higher levels of emotional cutoff and fusion with others, display higher levels of anxiety-related problems. Moreover, emotional cutoff and fusion with other traits emerged as a predictor of the probability of seeking support for anxiety disorders.

The students’ listening cognitive and metacognitive problems should be overcome with an effective listening strategy instruction. Besides, their learning style as the individual learners’ differences should be taken into account in getting a satisfactory listening outcome. To seek the solution, the present study aimed to find out quantitatively the effectiveness of implementation of Explicit (Meta)-cognitive collaboration strategy instruction (M-CCSI) and top-down strategy instructions (TDSI) toward the students’ listening proficiency viewed from their learning styles. The participants of the study were 50 Javanese EFL students at Muria University of Kudus, Indonesia. The data were gathered by using a listening proficiency test adopted from Longman TOEFL listening section and a questionnaire of visual, auditory, and kinesthetic (VAK) learning styles. Descriptive statistics, Independent Sample t-test, and Friedman two-way analysis of variance revealed that the experimental group has a significant effect of their listening proficiency after treated by using M-CCSI. Meanwhile, the control group has no significant effect on their listening proficiency after dealt with by using top down strategy (TDSI) as a general listening teaching. On the other hand, the result of two-way analysis of variance reveals that students’ listening proficiency was not influenced by learning styles including visual learners, auditory learners, and kinesthetic learners for both experimental group and control group. Thus, the findings imply that it is not essential for the lecturers of listening course to divide students into different learning styles in applying Explicit M-CCSI.

Neuropeptide Y (NPY) plays a mediatory role in cerebral insulin function by maintaining energy balance. The current study was designed to determine the role of insulin in food intake and its interaction with NPY receptors in 8 experiments using broiler cockerels (4 treatment groups per experiment, except for experiment 8). Chicks received control solution or 2.5, 5, or 10 ng of insulin in experiment 1 and control solution or 1.25, 2.5, or 5 μg of receptor antagonists B5063, SF22, or SML0891 in experiments 2, 3, and 4 through intracerebroventricular (ICV) injection, respectively. In experiments 5, 6, and 7, chicks received ICV injection of B5063, SF22, SML0891, or co-injection of an antagonist + insulin, control solution, and insulin. In experiment 8, blood glucose was measured. Insulin, B5063, and SML0891 decreased food intake, while SF22 led to an increase in food intake. The hypophagic effect of insulin was also reinforced by injection of B560, but ICV injection of SF22 destroyed this hypophagic effect of insulin and increased food intake (p < 0.05). However, SML0891 had no effect on decreased food intake induced by insulin (p > 0.05). At 30 min postinjection, blood sugar in the control group was higher than that in the insulin group (p < 0.05). Therefore, the NPY1 and NPY2 receptors mediate the hypophagic effect of insulin in broiler cockerels.
