Acetaminophen (APAP), a widely used analgesic/antipyretic agent, can cause liver injury through increased nitrative stress, leading to protein nitration. However, the identities of nitrated proteins and their roles in hepatotoxicity are poorly…
The peroxisome proliferator-activated receptor-alpha (PPAR alpha) regulates lipid homeostasis, particularly in the liver. This study was aimed at elucidating the relationship between hepatosteatosis and oxidative stress during fasting. Fasted…
The present study was designed to determine whether the diminution of growth hormone (GH) secretion that occurs in obese Zucker rats is related to alterations of GH-releasing factor (GRF) or somatostatin (SRIF) pituitary binding sites. Cold…
In order to investigate whether the impaired GH secretion associated with obesity is due to a pituitary disorder we studied GH mRNA levels by in situ hybridization in genetically obese and lean Zucker rats. The levels of GH mRNA were at least two…
Parkinsons disease (PD) is an age-related neurodegenerative disorder with a higher incidence in the male population. In the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD, 17 beta-oestradiol but not androgens were shown to…
The sex difference in Parkinson's disease, with a higher susceptibility in men, suggests a modulatory effect of sex steroids in the brain. Numerous studies highlight that sex steroids have neuroprotective properties against various brain injuries.…
Studies with the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of Parkinson's disease have shown the ability of 17 beta-estradiol to protect the nigrostriatal dopaminergic system. This paper reviews the signaling pathways mediating…
Mate mice were reported to display greater methamphetamine-induced neurotoxicity than females. The present study evaluated the involvement of phosphatidylinositol-3 kinase (PI3K)/Akt and extracellular signal-regulated kinase (ERK1/2) pathways in this…
Optimal information that should be included in ultrasound (US) heel bone mineral density (BMD) reports is not known. If additional information about further evaluation of patients with low heel BMD were included in reports, would responses for…
There are considerable data suggesting that vasoactive intestinal peptide (VIP) is involved in the regulation of PRL secretion; however, the role and cell of origin of anterior pituitary VIP remain to be determined. Immunocytochemical (ICC) studies…
We present a three-dimensional mineralizing model based on a hollow fiber bioreactor (HFBR) inoculated with primary osteoblasts isolated from embryonic chick calvaria. Using non-invasive magnetic resonance microscopy (MRM), the growth and development…
This article presents a case of acute mesenteric vein thrombosis with small bowel infarction associated with pancreatitis. Although a rare occurrence, the authors suggest this diagnosis should be considered as a possible complication of pancreatic…
Diabetes and obesity have reached an epidemic status worldwide. Diabetes increases the risk for cardiovascular disease and nonalcoholic fatty liver disease. Primary bile acids are synthesized in hepatocytes and are transformed to secondary bile acids…
Cortical mineralization of long bones was studied in collagen alpha2(I)-deficient mice (oim) used as a model for human osteogenesis imperfecta. Aspects of the age development of the mice were characterized by combining nanometer- to micrometer-scale…
Background: Neointimal formation plays an important role in the pathogenesis of coronary restenosis after percutaneous coronary intervention (PCI), especially in patients with diabetes mellitus. Recently, some studies have shown that…
We previously reported a strain-related difference in basal 3 beta-hydroxysteroid dehydrogenase-isomerase (3 beta HSD) activity in response to testosterone in cultured Leydig cells. The data suggested that the response to testosterone was androgen…
COL27A1 is a member of the collagen fibrillar gene family and is expressed in cartilaginous tissues including the anlage of endochondral bone. To begin to understand its role in skeletogenesis, the temporospatial distributions of its RNA message and…
Body tissues are traditionally classified as estrogen targets based on both the response to the hormone and the presence of estrogen receptors (ERs). We undertook the study on expression of ERalpha and ERbeta in the penis to identify…
Although synthesis of estrogen by male gonads has been well documented for over half a century, it is only recently that the role of estrogen in male reproductive events has gained appreciation. We recently reported abundant expression of estrogen…
