Journal ArticleDOI
Inhalation of fine particulate matter during pregnancy increased IL-4 cytokine levels in the fetal portion of the placenta.

TL;DR: Compared to control animals, IL-4 content was elevated in the fetal portion of the placenta in rats exposed to air pollution before and during pregnancy, suggesting that a placental inflammatory reaction may have occurred in response to exposure to fine particulate matter.
Journal ArticleDOI
Salt-Induced Cardiac Hypertrophy and Interstitial Fibrosis Are Due to a Blood Pressure–Independent Mechanism in Wistar Rats
Daniele N. Ferreira,Isis Akemi Katayama,Ivone B. Oliveira,Kaleizu T. Rosa,Luzia Naoko Shinohara Furukawa,Michella Soares Coelho,Dulce Elena Casarini,Joel Claudio Heimann +7 more
TL;DR: In this article, male Wistar rats were fed a normal (NSD: 1.3% NaCl), high 4 (HSD4: 4%), or high 8(HSD8: 8%) salt diet from weaning until 18 wk of age.
Salt-Induced Cardiac Hypertrophy and Interstitial Fibrosis Are Due to a Blood Pressure-Independent Mechanism
Daniele N. Ferreira,Isis Akemi Katayama,Ivone B. Oliveira,Kaleizu T. Rosa,Luzia Naoko Shinohara Furukawa,Michella Soares Coelho,Dulce Elena Casarini,Joel Cláudio Heimann +7 more
TL;DR: Evidence from the present study suggests that salt-induced AT(1) receptor internalization is probably due to angiotensin II binding, and hydralazine prevented high blood pressure (BP) and fibrosis, but not cardiomyocyte hypertrophy.
Journal ArticleDOI
High-Salt Intake Induces Cardiomyocyte Hypertrophy in Rats in Response to Local Angiotensin II Type 1 Receptor Activation
Isis Akemi Katayama,Rafael Canavel Pereira,Ellen Priscila Brito Dopona,Maria Heloisa Massola Shimizu,Luzia Naoko Shinohara Furukawa,Ivone B. Oliveira,Joel Claudio Heimann +6 more
TL;DR: The primary finding was the occurrence of significant BP-independent CH in the HS+HZ group and a partial or total prevention of such hypertrophy via treatment with NAC or LOS, and the link of oxidative stress with CH in the authors' experimental model is very interesting and stimulates further evaluation for its full comprehension.
Journal ArticleDOI
Sex-specific differences in endoplasmic reticulum aminopeptidase 1 modulation influence blood pressure and renin-angiotensin system responses.

TL;DR: Lowering ERAP1 led to volume expansion and increased BP in males and females, whereas in females the volume expansion was due to impaired renovascular function with normal ALDO levels.
