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.

Salt-Induced Cardiac Hypertrophy and Interstitial Fibrosis Are Due to a Blood Pressure-Independent Mechanism

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.

High-Salt Intake Induces Cardiomyocyte Hypertrophy in Rats in Response to Local Angiotensin II Type 1 Receptor Activation

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.
