Hyperoxia-induced neutrophil infux in neonatal rats may contribute to impaired lung development through oxidative DNA damage. To determine whether blocking neutrophil influx prevents DNA damage, we treated newborn rats with 95% O2 beginning at birth, and at 3 and 4 d with nonimmune immunoglobulin G (IgG) (control) or anti-cytokine-induced neutrophil chemoattractant (CINC). At 8 d, lungs were in...

Downloa pose: We hypothesized that the basal apoptotic rate (BAR) of a cancer would predict sensitivity sequent proapoptotic stimuli. To explore this, preclinical and clinical BAR assays were developed ring cumulative apoptotic events through ELISAs for soluble caspase-cleaved cytokeratin 18 (M30) lized to either cell number increase or total tumor volume, respectively. erimental Design: The BA...

BACKGROUND The inhibitory effects of black cohosh extracts (Cimicifuga syn. Actaea racemosa L.) on the proliferation of human breast cancer cells were reported recently. In this study, we turned examined another hormone-dependent, epidemiologically important tumor disease, prostate cancer. The cell growth inhibitory effect of an isopropanolic extract of black cohosh (iCR) on androgen-sensitive ...

BACKGROUND Stress of the endoplasmic reticulum (ER) leading to activation of the unfolded protein response (UPR) and alveolar epithelial cell (AEC) apoptosis may play a role in the pathogenesis of idiopathic pulmonary fibrosis (IPF). Our objectives were to determine whether circulating caspase-cleaved cytokeratin-18 (cCK-18) is a marker of AEC apoptosis in IPF, define the relationship of cCK-18...

Pregnant women who smoke are at greater risk of delivering a growth-restricted infant than nonsmoking mothers. We wanted to see if apoptosis could be involved in the mechanisms behind smoke-induced growth restriction, and our aim was to compare apoptosis in the placenta of smoking mothers giving birth to growth-restricted infants and nonsmoking mothers with infants of appropriate weight. The pr...

BACKGROUND Unexplained intrauterine growth restriction (IUGR) may be a consequence of placental insufficiency; however, its etiology is not fully understood. We surmised that defective placentation in IUGR dysregulates cellular bioenergic homeostasis, leading to increased autophagy in the villous trophoblast. The aims of this work were (1) to compare the differences in autophagy, p53 expression...

BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide with no specific treatment. Weight loss is the most effective therapeutic strategy in its management; however, there is no consensus on its specifics. Thus, this study was conducted to evaluate the effects of weight loss on liver enzymes, markers of inflammation, oxidative stress and CK18-M30 (cytoker...

conclusions this intervention offers a practical approach for treatment of patients with nafld with diet therapy. patients and methods forty four patients with nafld received a diet including a 500 to 1000 kcal per day intake reduction as30% fat, 15% protein, and 55% carbohydrate for six months. anthropometric parameters, alanine aminotransferase (alt), aspartate aminotransferase (ast), gamma g...

Liver biopsy still remains the gold standard for diagnosing nonalcoholic steatohepatitis (NASH), but with limitations. There is an urgent need to develop noninvasive tests that accurately distinguish NASH from simple steatosis. The purpose of this meta-analysis was to evaluate the diagnostic value of serum biomarkers including cytokeratin 18 (CK-18), fibroblast growth factor 21 (FGF-21), and co...
