Two experiments assessed whether human affective learning is sensitive to occasion setting. The first experiment (N 5 18) employed a within-subjects, sequential feature positive design (X → A1/A2). Modulation of blink startle, an index of affective learning, was larger during A1 than during A2, suggesting that participants had learned a modulatory relationship. Experiment 2 (N 5 32) assessed wh...
Background Circulating angiotensin-2 levels (A2) protect the circulation against sudden falls in blood pressure. A2 is generated by the enzymatic action of angiotensin converting enzyme (ACE) on angiotensin-1. The ACE genes have 2 allellic forms, with the presence ‘I’ or absence ‘D’ of a 287 base pair intron of the gene. The deletion ‘DD’ genotype is associated with high A2 generation & higher ...
Cyclin‑A2, which is downregulated following birth, has previously been established as a key regulator of the cell cycle. The present study aimed to detect the effects of cyclin‑A2 on myocardial cells by using recombinant adeno‑associated virus 9 (rAAV9). Sixty mice were selected and randomly divided into two groups (n=30). The control group were injected with saline and the experimental group w...
The aim of the study was to assess the instantaneous spectral components of heart rate variability (HRV) and systolic blood pressure variability (SBPV) and determine the low-frequency (LF) and high-frequency baroreflex sensitivity (HF-BRS) during a graded maximal exercise test. The first hypothesis was that the hyperpnea elicited by heavy exercise could entail a significant increase in HF-SBPV ...
Calcium dependent phospholipase A2 activity in the mixed micelles of 1-palmitoyl-2-oleoyl-phosphatidylglycerol and cholate was measured in sera of 39 patients with Crohn's disease, 40 patients with ulcerative colitis, and 40 healthy controls. The phospholipase A2 activity was significantly raised in those sera of the patients with active Crohn's disease and those with moderate and severe ulcera...
