Prolactin (PRL) increased basal dopamine (DA) release and attenuated amphetamine (AMPH)-stimulated DA release in vitro from rat corpus striatum in a concentration-dependent manner with 10(-5) M PRL being the most effective. The effects of PRL on DA…

A model calcifying system of primary osteoblast cell cultures derived from normal embryonic chicken calvaria has been flown aboard the shuttle, Endeavour, during the National Aeronautics and Space Administration (NASA) mission STS-59 (April 9-20,…

This study examines the tissue engineering of a human ear model through use of bovine chondrocytes isolated from four different cartilaginous sites (nasoseptal, articular, costal, and auricular) and seeded onto biodegradable poly(l-lactic acid) and…

We recently developed a sensitive method using biotin-N-maleimide (biotin-NM) as a probe to positively identify oxidized mitochondrial proteins. In this study, biotin-NM was used to identify oxidized cytosolic proteins in alcohol-fed mouse livers.…

To understand further the effects of spaceflight on osteoblast-enriched cultures, normal chicken calvarial osteoblasts were flown aboard shuttle flight STS-77, and the total number of attached cells was determined. Spaceflight and control cultures…

To understand further the role of gravity in osteoblast attachment, osteoblasts were subjected to hypergravity conditions in vitro. Scanning electron microscopy of all confluent coverslips from FPA units show that the number of attached osteoblasts…

Substrate attachment is crucial for normal growth and differentiation of many cell types. To better understand the role of gravity in osteoblast attachment and growth in vitro, 17-day-old embryonic chick calvarial osteoblasts were subjected to…

This study compares bovine chondrocytes harvested from four different animal locations-nasoseptal, articular, costal, and auricular-for tissue-engineered cartilage modeling. While the work serves as a preliminary investigation for fabricating a human…

To demonstrate improved healing of a midline laparotomy after application of mesenchymal stromal cells and platelet-rich plasma on a collagen matrix and introduce a potential cellular-based therapy for the prevention of incisional hernia formation.…

Objective. In OA, there is enhanced expression of pro-inflammatory cytokines such as IL-1 beta in the affected joint. Delphinidin, an anthocyanidin found in pigmented fruits and vegetables, has been shown to possess anti-inflammatory and antioxidant…

Objective: The Hartley guinea pig develops articular cartilage degeneration similar to that seen in idiopathic human osteoarthritis (OA). We investigated whether the application of pulsed low-intensity ultrasound (PLIUS) to the Hartley guinea pig…

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…

Costa AR, Panda NC, Yong S, Mayorga ME, Pawlowski GP, Fan K, Penn MS, Laurita KR. Optical mapping of cryoinjured rat myocardium grafted with mesenchymal stem cells. Am J Physiol Heart Circ Physiol 302: H270-H277, 2012. First published October 28,…

Endothelial cell polarization and directional migration is required for angiogenesis. Polarization and motility requires not only local cytoskeletal remodeling but also the motion of intracellular organelles such as the nucleus. However, the…

In vitro studies have implicated chemokine receptors in consumption and clearance of specific ligands. We studied the role that various signaling chemokine receptors play during ligand homeostasis in vivo. We examined the levels of ligands in serum…

Chromium(V)-mediated oxidative damage of deoxyribonucleic acids was investigated at neutral pH in aqueous solution by utilizing bis(2-ethyl-2-hydroxybutanato)oxochromate(V) (I) and bis(hydroxyethyl)amino-tris(hydroxymethyl)methane)oxochromate(V)…

Heat shock protein 27 (Hsp27) is a chaperone protein, and its expression is increased in response to various stress stimuli including anticancer chemotherapy, which allows the cells to survive and causes drug resistance. We previously identified lead…

Interbody cage devices, used to assist interbody fusion, are rapidly gaining popularity in the surgical management of chronic low back pain. This update provides a structural classification of commonly used devices and assesses them against a set of…

Human noroviruses (HuNoVs) are the most common cause of acute viral gastroenteritis worldwide and are a leading cause of foodborne disease. Their environmental persistence and purported resistance to disinfection undoubtedly contribute to their…

Single stranded microRNAs and their antagomirs are unstable and polyanionic, which impedes efficient cellular uptake and reduces half-life. Therefore, effective delivery systems with low toxicity for microRNAs are urgently needed for the success of…

Gene therapy has drawn significant interest in the past two decades since it provides a promising strategy to treat both genetic disorders and acquired diseases. However, the transfer of gene therapy to clinical applications is troubled with many…

Vitamin D-binding protein (DBP) is a multi-functional serum protein that is converted to vitamin D-binding protein-macrophage activating factor (DBP-maf) by post-translational modification. DBP-maf is a new cytokine that mediates bone resorption by…

Gold nanoshells (AuNSs) are currently being investigated as nanocarriers for drug delivery systems and have both diagnostic and therapeutic applications, including photothermal ablation, hyperthermia, drug delivery, and diagnostic imaging,…

Gene expression levels for type II collagen and aggrecan have been determined as potential measures and disease markers of human osteoarthritis in patients undergoing total knee arthroplasty. In this regard, specimens of affected articular cartilage…

During development and evolution, the morphology of ectodermal organs can be modulated so that an organism can adapt to different environments. We have proposed that morphoregulation can be achieved by simply tilting the balance of molecular…

We provide a comparative analysis of protein adsorption, primary human cell behavior, and biofilm formation on modified titanium substrates of either micro-, nano-, or hybrid micro/nano-scale feature sizes. While studies revealed that nano-scale…
