Example Input: This paper examines the effect of one form of chronic stress--household crowding--on psychological well-being, as measured by multiple inverse indicators of psychological well-being. We rely on data from a large (n = 2017) random sample of households in Bangkok, Thailand, a context that has a higher level and broader range of crowding than typically found in the United States. Objective household crowding is found to be detrimental to psychological well-being, controlling for a number of background characteristics. The effect of objective crowding is mediated by subjective crowding, which has strong, consistent and direct detrimental effects on well-being. There is no evidence of a gender effect. Extended family households are not uncommon in Bangkok, but the effects of objective and subjective crowding are similar in both two- and three-generation households, as well as in one- and multiple-couple households. The argument that subjective crowding is an effect, rather than a cause, of psychological well-being is examined and rejected. The findings suggest that crowding, as a chronic source of stress, constitutes a major threat to psychological well-being. Although the empirical analyses are based on data from one city, we frame the issue of household crowding in a historical and theoretical context in order to suggest in which cultural settings household crowding is most likely to have detrimental effects on psychological well-being.
Example Output: Chronic stress and psychological well-being: evidence from Thailand on household crowding.

Example Input: In pregnancy, trophoblast invasion and uterine spiral artery remodelling are important for lowering maternal vascular resistance and increasing uteroplacental blood flow. Impaired spiral artery remodelling has been implicated in pre-eclampsia, a major complication of pregnancy, for a long time but the underlying mechanisms remain unclear. Corin (also known as atrial natriuretic peptide-converting enzyme) is a cardiac protease that activates atrial natriuretic peptide (ANP), a cardiac hormone that is important in regulating blood pressure. Unexpectedly, corin expression was detected in the pregnant uterus. Here we identify a new function of corin and ANP in promoting trophoblast invasion and spiral artery remodelling. We show that pregnant corin- or ANP-deficient mice developed high blood pressure and proteinuria, characteristics of pre-eclampsia. In these mice, trophoblast invasion and uterine spiral artery remodelling were markedly impaired. Consistent with this, the ANP potently stimulated human trophoblasts in invading Matrigels. In patients with pre-eclampsia, uterine Corin messenger RNA and protein levels were significantly lower than that in normal pregnancies. Moreover, we have identified Corin gene mutations in pre-eclamptic patients, which decreased corin activity in processing pro-ANP. These results indicate that corin and ANP are essential for physiological changes at the maternalfetal interface, suggesting that defects in corin and ANP function may contribute to pre-eclampsia.
Example Output: Role of corin in trophoblast invasion and uterine spiral artery remodelling in pregnancy

Example Input: Reduced dietary methionine intake (0.17% methionine, MR) and calorie restriction (CR) prolong lifespan in male Fischer 344 rats. Although the mechanisms are unclear, both regimens feature lower body weight and reductions in adiposity. Reduced fat deposition in CR is linked to preservation of insulin responsiveness in older animals. These studies examine the relationship between insulin responsiveness and visceral fat in MR and test whether, despite lower food intake observed in MR animals, decreased visceral fat accretion and preservation of insulin sensitivity is not secondary to CR. Accordingly, rats pair fed (pf) control diet (0.86% methinone, CF) to match the food intake of MR for 80 weeks exhibit insulin, glucose, and leptin levels similar to control-fed animals and comparable amounts of visceral fat. Conversely, MR rats show significantly reduced visceral fat compared to CF and PF with concomitant decreases in basal insulin, glucose, and leptin, and increased adiponectin and triiodothyronine. Daily energy expenditure in MR animals significantly exceeds that of both PF and CF. In a separate cohort, insulin responses of older MR animals as measured by oral glucose challenge are similar to young animals. Longitudinal assessments of MR and CF through 112 weeks of age reveal that MR prevents age-associated increases in serum lipids. By 16 weeks, MR animals show a 40% reduction in insulin-like growth factor-1 (IGF-1) that is sustained throughout life; CF IGF-1 levels decline much later, beginning at 112 weeks. Collectively, the results indicate that MR reduces visceral fat and preserves insulin activity in aging rats independent of energy restriction.
Example Output:
Methionine restriction decreases visceral fat mass and preserves insulin action in aging male Fischer 344 rats independent of energy restriction.
