Development of a greenhouse gas - air pollution interactions and synergies model for Korea (GAINS-Korea).

This study aimed to create Greenhouse Gas - Air Pollution Interactions and Synergies (GAINS)-Korea, an integrated model for evaluating climate and air quality policies in Korea, modeled after the international GAINS model. GAINS-Korea incorporates specific Korean data and enhances granularity for enabling local government-level analysis. The model includes source-receptor matrices used to simulate pollutant dispersion in Korea, generated through CAMx air quality modeling.

The present study aimed to examine whether there is an altered regulation of local hormonal systems in the kidney following the treatment of glycyrrhizic acid (GA), the active ingredient in licorice. Male Sprague-Dawley rats were treated with GA for 3 weeks. The expression of mineralocorticoid receptor (MR) was determined in the kidney by immunoblotting and real-time polymerase chain reaction (PCR).

Continuous renal replacement therapy for the treatment of acute kidney injury.

Background/aims: Continuous renal replacement therapy (CRRT) has been widely used for treating critically ill patients with acute kidney injury (AKI). Whether CRRT is better than intermittent hemodialysis for the treatment of AKI remains controversial. We sought to identify the clinical features that can predict survival for the patients who are treated with CRRT.

Effects of rosiglitazone on heat shock protein and the endothelin system in deoxycorticosterone acetate-salt hypertensive rats.

The deoxycorticosterone acetate (DOCA)-salt rat is known as a model of volume dependent hypertension and characterized by increased cardiac endothelin-1 (ET-1) content. Recently, it has been reported that rosiglitazone (RGT), a peroxisome proliferator-activated subtype gamma receptor agonist, shows blood pressure lowering effect. We investigated whether DOCA-salt hypertension is associated with altered expression of heat shock proteins (HSP) and ET-1 in the heart, aorta, and kidney, and whether RGT changes HSP expression and ET-1 in association with its blood pressure lowering effect.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disease. There are some reports in the literature concerning unilateral ADPKD. However, in adults, only a few cases of unilateral ADPKD with agenesis of contralateral kidney have been reported.

Renal vein and inferior vena cava thrombosis associated with acute pancreatitis.

Renal vein thrombosis (RVT) is a well-recognized complication of the nephrotic syndrome, but it is extremely rare in patients with acute pancreatitis. Vascular thrombosis complicating pancreatitis is thought to be due to release of proteolytic enzymes from the pancreas and direct vasculitis. Peripancreatic vessels are most commonly involved in the complications associated with pancreatitis.
