Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

The relationship of bipolar disorder (BD) and altered thyroid function is increasingly recognized. Recently, a behavioral phenotype of co-occurring deviance on the Anxious/Depressed (A/D), Attention Problems (AP), and Aggressive Behavior (AB) syndrome scales has been identified as the Child Behavior Checklist Dysregulation Profile (CBCL-DP), which itself has been linked to BD. This study tested for differences in thyroid function within a sample of n=114 psychiatric children and adolescents with and without the CBCL-DP.', 'A CBCL-DP score was generated based on the composite of the crucial CBCL syndrome scales (A/D, AP, AB). Participants with a CBCL-DP score >or=2.5 SDs above average constituted the CBCL-DP subgroup (n=53). Those with CBCL-DP scores of 1 SD or less above average percentile were regarded as controls (n=61). Groups were compared regarding serum levels of TSH, fT3 and fT4.', 'In participants showing the CBCL-DP, basal serum TSH was elevated compared to controls. More CBCL-DP subjects than controls showed subclinical hypothyroidism. No differences were observed for serum fT3 and fT4 levels.
Is severe affective and behavioral dysregulation in youth associated with increased serum TSH?

Dyspnoea is a threatening sensation of respiratory discomfort that presents many similarities with pain. Experimental dyspnoea in healthy subjects induces analgesia. This 'dyspnoea-pain counter-irritation' could, in reverse, imply that relieving dyspnoea in patients with chronic respiratory diseases would lower their pain thresholds.", 'We first determined pressure pain thresholds in 25 healthy volunteers (22-31\u2005years; 13 men; handheld algometer), during unloaded breathing (BASELINE) and during inspiratory threshold loading (ITL). Two levels of loading were used, adjusted to induce dyspnoea self-rated at 60% or 80% of a 10\u2005cm visual analogue scale (ITL6 and ITL8). 18 patients with chronic respiratory failure due to amyotrophic lateral sclerosis (ALS) were then studied during unassisted breathing and after 30 and 60\u2005min of non-invasive ventilation-NIV30 and NIV60-(same dyspnoea evaluation).', 'In healthy volunteers, pressure pain thresholds increased significantly in the deltoid during ITL6 (p<0.05) and ITL8 (p<0.05) and in the trapezius during ITL8 (p<0.05), validating the use of pressure pain thresholds to study dyspnoea-pain counter-irritation. In patients with ALS, the pressure pain thresholds measured in the deltoid during unassisted breathing decreased by a median of 24.5%-33.0% of baseline during NIV30 and NIV60 (p<0.05).
Does relieving dyspnoea by non-invasive ventilation decrease pain thresholds in amyotrophic lateral sclerosis?

To assess the effects of protein C activator (PCA) from Agkistrodon halys snake venom on cardiac fibrosis in streptozotocin (STZ) induced diabetic rat model, and investigate the mechanisms of its action.', 'PCA was identified by one-dimensional reversed phase liquid chromatography - mass spectrometry/mass spectrometry. Male Sprague-Dawley rats (120-140 g) were randomly assigned to negative control (NC) and diabetic group. Diabetes was induced by STZ in high-fat diet fed rats. Diabetic group was subdivided into three groups: diabetic group (DM), diabetic group treated with PCA (0.5, 2, and 8 mg/kg), and diabetic group treated with metformin (5 mg/kg, positive control). NC and DM groups received the same volume of distilled water. Left ventricular mass index (LVWI) and collagen volume fraction were measured by hematoxylin and eosin and Masson staining. Transforming growth factor beta-1 (TGF-β1) and interleukin 1 beta (IL-1β) levels were determined by enzyme-linked immunosorbent assay.', 'The diabetic rat model was successfully established by STZ induction and high-fat diet. Glucose level, LVWI, TGF-β1 and IL-1β level, and collagen volume fraction were significantly reduced in diabetic rats treated by PCA in a dose-dependent manner (P<0.050), especially in the high dose (8 mg/kg) group (P<0.010), compared to diabetes group. The high dose PCA had the same effect as metformin positive control in reducing the level of fasting blood glucose. PCA decreased the expression of MMP-2 and reduced that of TIMP-2.
