Acute kidney injury (AKI) is a common complication in critically ill patients. Urinary excretion of liver-type fatty acid-binding protein (L-FABP), which is expressed in the proximal tubules, reflects the presence of tubular injury. Urinary excretion of podocalyxin (PCX), a glycoprotein prominently expressed on podocytes, is associated with podocyte injury.(More)
INTRODUCTION Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is characterized by features other than increased pulmonary vascular permeability. Pulmonary vascular permeability combined with increased extravascular lung water content has been considered a quantitative diagnostic criterion of ALI/ARDS. This prospective, multi-institutional,(More)
BACKGROUND High-mobility group 1 (HMGB-1) is a late mediator of endotoxin lethality in mice. The release of HMGB-1 is delayed compared to other proinflammatory cytokines that mediate shock and tissue injury. The purpose of this study was to investigate the role of HMGB-1 levels in response to hepatic ischemia, hepatic I/R injury, and the relationship(More)
INTRODUCTION The Berlin definition divides acute respiratory distress syndrome (ARDS) into three severity categories. The relationship between these categories and pulmonary microvascular permeability as well as extravascular lung water content, which is the hallmark of lung pathophysiology, remains to be elucidated. The aim of this study was to evaluate(More)
The hypoplastic lung in congenital diaphragmatic hernia (CDH) has both a quantitative and qualitative reduction in surfactant. Tumor necrosis factor-α (TNF-α) drastically decreases surfactant phospholipids synthesis by isolated human type II pneumocytes. Recently, it was shown that TNF-α mRNA expression is increased in human hypoplastic CDH lung. Antenatal(More)
Although the Tsushima leopard cat (Prionailurus bengalensis euptilurus) is one of the most endangered mammals in Japan, its reproductive physiology and endocrinology have been not elucidated. The objective was to establish the non-invasive monitoring of reproductive endocrinology in a female Tsushima leopard cat and to identify the types of fecal(More)
The purpose of this study was to compare structural changes in the pulmonary vasculature in newborns with congenital diaphragmatic hernia (CDH) complicated by persistent pulmonary hypertension (PPH) and stillborns with CDH. Victorian blue van Gieson (VVG) staining and immunostaining with anti-alpha smooth-muscle actin (ASMA) was performed on lung tissue(More)
BACKGROUND In patients with severe sepsis, depression of cardiac performance is common and is often associated with left ventricular (LV) dilatation to maintain stroke volume. Although it is essential to optimize cardiac preload to maintain tissue perfusion in patients with severe sepsis, the optimal preload remains unknown. This study aimed to evaluate the(More)
The present experiments were carried out to investigate the usefulness of measuring peripheral tissue metabolism for the clinical assessment of shock. Male Wistar/ST rats (8 weeks-old) were used. All rats were placed in a supine position while anesthetized. A tube for measuring arterial pressure and collecting blood samples was cannulated into the femoral(More)
Staphylococcus aureus is a major human pathogen that elaborates several exotoxins. Among these are the bicomponent leukotoxins (BCLs), which include γ-hemolysin, Panton-Valentine leukocidin (PVL), and LukDE. The toxin components are classified as either F or S proteins, which are secreted individually and assemble on cell surfaces to form hetero-oligomeric(More)
