BACKGROUND: Icrucumab (ICR) and ramucirumab (RAM) bind vascular endothelial growth factor (VEGF) receptors 1 and 2 (VEGFR-1 and -2), respectively. This open-label, randomized phase II study evaluated their efficacy and safety in combination with capecitabine (CAP) in patients with previously treated unresectable, locally advanced or metastatic breast cancer. METHODS: Patients were randomly assigned (1:1:1) to receive CAP (1,000 mg/m(2) orally twice daily, days 1-14) alone or in combination with RAM (10 mg/kg intravenously [IV], days 1 and 8) (RAM + CAP) or ICR (12 mg/kg IV, days 1 and 8) (ICR + CAP) every 21 days...

BACKGROUND: Microglia in the central nervous system (CNS) were reported to play crucial role in neurodegeneration. Previous studies showed that P2Y6 receptor (P2Y6R) mainly contributed to microglia activation and phagocytosis in CNS. However, the level of P2Y6R in Parkinson's disease (PD) patients is unclear. Therefore, we measured the level of P2Y6R in PD patients and speculated whether it could be a potential biomarker for PD. Given on the basis that P2Y6R was higher in PD patients, we further explored the mechanisms underlying P2Y6R in the pathogenesis of PD...

Bioactive coatings which support the adhesion of late-outgrowth peripheral blood endothelial progenitor cells (EOCs) are actively being investigated as a means to promote rapid endothelialization of "off-the-shelf," small-caliber arterial graft prostheses following implantation. In the present work, we evaluated the behavior of EOCs on thromboresistant graft coatings based on the collagen-mimetic protein Scl2-2 and poly(ethylene glycol) (PEG) diacrylate. Specifically, the attachment, proliferation, migration, and phenotype of EOCs on PEG-Scl2-2 hydrogels were evaluated as a function of Scl2-2 concentration (4, 8, and 12 mg/mL) relative to human umbilical vein endothelial cells (HUVECs)...

The lysosomal storage disorder (LSD) metachromatic leukodystrophy (MLD) is caused by a deficiency of the soluble, lysosomal hydrolase arylsulfatase A (ASA). The disease is characterized by accumulation of 3-O-sulfogalactosylceramide (sulfatide), progressive demyelination of the nervous system and premature death. Enzyme replacement therapy (ERT), based on regular intravenous injections of recombinant functional enzyme, is in clinical use for several LSDs. For MLD and other LSDs with central nervous system (CNS) involvement, however, ERT is limited by the blood-brain barrier (BBB) restricting transport of therapeutic enzymes from the blood to the brain...

We prepared a DIC model by administrating LPS to cynomolgus monkeys, and investigated its potential for evaluations of new medicines for DIC therapy. Peripheral blood mononuclear cells (PBMC) collected from cynomolgus monkeys were incubated with LPS (8 types), and TNF-α levels in the media were measured. LPS from Escherichia coli (K-235) was most appropriate in terms of larger increases and smaller variation in TNF-α levels. PBMC from rats, cynomolgus monkeys or humans were incubated with LPS (K-235), and the TNF-α response to LPS was investigated...

BACKGROUND: Early diagnosis and treatment of non-Hodgkin lymphoma (NHL) are progressively important. It has been shown that aberrant promoter methylation contributes to the development and progression of lymphoma. We tried to explore the effect of methylation of p16 and shp1 genes in plasma in the diagnosis of B-NHL patients. METHODS: The methylation of p16 and shp1 genes in plasma were detected by methylation specific polymerase chain reaction in 103 patients with B-NHL, and compared with peripheral blood leukocytes (PBLs) and formaldehyde-fixed paraffin-embedded (FFPE) tumor tissues...

Meningococcal infection is an important public health concern. Neisseria meningitidis usually colonizes the nasopharynx of healthy adolescents and adults and remains as asymptomatic colonizer, while in rare cases it may present as invasive disease as either meningitis or septicemia or both. Most of the cases have typical presentation of rashes. We hereby present a case of a 40-year-old male who presented with meningococcal meningitis and peripheral digital gangrene but without development of typical rashes...

The neuropeptide substance P (SP) is an important mediator of neurogenic inflammation within the central and peripheral nervous systems. SP has been shown to induce the expression of pro-inflammatory cytokines implicated in the pathogenesis of several disorders of the human brain via the neurokinin-1 receptor (NK-1R). Ketamine, an intravenous anesthetic agent, functions as a competitive antagonist of the excitatory neurotransmission N-methyl-D‑aspartate (NMDA) receptor, and also antagonizes the NK-1R by interfering with the binding of SP...

Vein location and assessment are essential to improve the success rates for vascular access. However, problems remain with first attempt success rates for peripheral cannulation and locating difficult veins. Practitioners may not be aware of developments in technology and aids to assist in the location and assessment of veins to achieve vascular access. This article provides an overview of two vein location aids that can be used to locate difficult veins: the IV-eye vein imager and the Vacuderm tourniquet. It discusses the patient factors that can increase the difficulty of vein assessment and location, and emphasises the importance of vessel health and preservation, and vein palpation...

NSCLC is a leading cause of morbidity and mortality worldwide. It includes adeno- and squamous cell carcinoma. In the background, COPD and smoking play a vital role in development of NSCLC. Local progression and metastasis of NSCLC has been associated with various mechanisms, but in particular by a process called epithelial mesenchymal transition (EMT), which is implicated in COPD pathogenesis. In this study, we have investigated whether expression of EGFR (activation marker) and S100A4, vimentin and N-cadherin (as EMT) is different both in central and leading edge of NSCLC and to what extent related to EMT activity of both small and large airways, stage and differentiation of NSCLC...

INTRODUCTION: Kisspeptin, which is encoded by the KISS1 gene and acts via GPR54, plays a role in the regulation of reproductive functions. Expression of KISS1 and GRPR54 has been found in peripheral tissues, including adipose tissue, and was shown to be influenced by metabolic status. PURPOSE: We hypothesized that kisspeptin could be involved in regulation of lipid metabolism in the mouse 3T3-L1 cell line and in isolated rat adipocytes. METHODS: First, we characterized expression profiles of KISS1 and GPR54 mRNA and proteins in adipose cells isolated from male rats...

Glioblastoma (GBM), an aggressive grade IV astrocytoma, is the most common primary malignant adult brain tumor characterized by extensive invasiveness, heterogeneity, and angiogenesis. Standard treatment options such as radiation and chemotherapy have proven to be only marginally effective in treating GBM because of its invasive nature. Therefore, extensive efforts have been put forth to develop tumor-tropic stem cells as viable therapeutic vehicles with potential to treat even the most invasive tumor cells that are harbored within areas of normal brain...

Chronic lung transplant rejection (termed chronic lung allograft dysfunction [CLAD]) is the main impediment to long-term survival after lung transplantation. Bone marrow-derived mesenchymal stromal cells (MSCs) represent an attractive cell therapy in inflammatory diseases, including organ rejection, given their relative immune privilege and immunosuppressive and tolerogenic properties. Preclinical studies in models of obliterative bronchiolitis and human trials in graft versus host disease and renal transplantation suggest potential efficacy in CLAD...
