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.
PROBLEM: It has been shown that the circulating Renin-Angiotensin System (RAS) is activated during normal pregnancy, but little is known about RAS in pregnancies complicated by gestational diabetes (GDM). GDM is considered not merely a temporary condition, but a harbinger of hypertension and type 2 diabetes. The aim of this study was to evaluate the circulating RAS profile in normotensive women with GDM at the third trimester of pregnancy and to compare the results with healthy pregnant and non-pregnant age-matched women.', 'The diagnostic criteria for GDM followed the recommendations of the American Diabetes Association. Angiotensin I (Ang I), Angiotensin II (Ang II) and Angiotensin 1-7 [Ang-(1-7)] were determined in 24 pregnant patients with GDM; 12 healthy pregnant women and 12 non-pregnant women by radioimmunoassay.', 'Levels of Ang I, Ang II and Ang-(1-7) were higher in pregnant women (p<0.05), but showed a different pattern in the GDM group, in which reduced Ang-(1-7) circulating levels were found (p<0.05). This observation was confirmed by the significantly lower Ang-(1-7)/Ang I ratio (p<0.05).

SOLUTION: Does the pregnancy-induced increase of plasma angiotensin- ( 1-7 ) is blunt in gestational diabetes?

PROBLEM: Neurotensin-1 (NT1) receptor agonists have been proposed as putative antipsychotic drugs. Recently, brain-penetrating NT analogs produced by stability-enhancing modification of the smallest NT fragment, NT(8-13), have demonstrated antipsychotic-like efficacy after acute systemic injection in several preclinical animal tests predictive for antipsychotic efficacy. However, the evidence regarding the persistence versus tolerance of these effects after repeated administration is ambiguous. Previous studies have used compounds that nonselectively activated both NT1 and NT2 receptors or used continuous slow, central infusion of doses rather than daily acute administration, both factors which may have contributed to the ambiguity in the literature regarding the emergence of tolerance.', 'To determine if tolerance develops to the antipsychotic-like effects of NT1 receptor agonists, we investigated the effects of subchronic daily systemic administration of PD149163, a brain-penetrating NT analog with selectivity for the NT1 receptor, on amphetamine-induced locomotor activation, a classic preclinical test of antipsychotic efficacy.', 'Sprague-Dawley rats were pretreated with eight consecutive daily subcutaneous (SC) injections of PD149163 or saline. On the ninth day, rats received a pair of SC injections consisting of PD149163 or saline, followed by amphetamine (0.5 mg/kg) or saline. Locomotor activity was then measured in photobeam-equipped cages.', "The results indicated that repeated daily administration of PD149163 was able to antagonize amphetamine's locomotor-activating effect comparable to that of the first dose, despite that repeated administration of PD149163 produced an increase in baseline locomotor activity not seen after the first dose.

SOLUTION: Does the reversal of amphetamine-induced locomotor activation by a selective neurotensin-1 receptor agonist exhibit tolerance?

PROBLEM: Chemoradiotherapy for non-small cell lung cancer can impair pulmonary function, particularly when it is followed by surgery. This study aimed to document the changes in respiratory function as a result of a perioperative intensive pulmonary rehabilitation program in patients with non-small cell lung cancer who underwent induction chemoradiotherapy.', 'A total of 82 consecutive patients underwent pulmonary resection after undergoing induction chemoradiotherapy. A pulmonary rehabilitation program was started at the same time as the induction chemoradiotherapy. Standard respiratory function tests were performed before and after induction chemoradiotherapy. Treatment-related mortality and the incidence of postoperative respiratory complications were investigated. The Wilcoxon signed-rank test was used to analyze the differences in spirometric changes.', 'All patients underwent a pulmonary rehabilitation program for an average of 10 weeks. Significant increases were observed in forced vital capacity (+6.4%, P = .0096) and forced expiratory volume in 1 second (+10.4%, P < .0001). Diffusing capacity of the lung for carbon monoxide decreased (-14.0%, P < .0001). Patients with respiratory impairment (forced vital capacity <80% predicted or forced expiratory volume in 1 second/forced vital capacity <70%) showed significant improvements in forced vital capacity (+13.9%, P = .0025) and forced expiratory volume in 1 second (+22.5%, P < .0001). Significant increases were observed in forced vital capacity (+7.0%, P = .0042) and forced expiratory volume in 1 second (+10.8%, P = .0001) in patients with a smoking history. There was no mortality, and postoperative respiratory morbidity was 6.1%.

Does pulmonary rehabilitation during induction chemoradiotherapy for lung cancer improve pulmonary function?
