REVIEW
David S Goldstein, Irwin J Kopin
In this review we describe a series of major concepts introduced during the past 150years that have contributed to our current understanding about how physiological processes required for well-being and survival are regulated. One can theorize that hierarchical networks involving input-output relationships continuously orchestrate and learn adaptive patterns of observable behaviors, cognition, memory, mood, and autonomic systems. Taken together, these networks function as "good regulators" determining levels of internal variables and act as if there were homeostatic comparators ("homeostats")...

BACKGROUND: Poor-risk patients with metastatic renal-cell carcinoma remain poorly characterized in prospective clinical trials. Therefore, we sought to provide a comprehensive analysis of this patient population, defined by 3 widely used prognostic models, treated with targeted therapy. PATIENTS AND METHODS: We conducted a pooled retrospective analysis of 4736 metastatic renal-cell carcinoma patients treated on phase 2 and 3 clinical trials. Poor-risk patients were defined according to the Memorial Sloan Kettering Cancer Center (MSKCC), International Metastatic Renal Cell Carcinoma Database Consortium (IMDC), and Hudes risk models...

BACKGROUND: Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) have a poor prognosis, even in the rituximab era. Several studies have reported the clinical importance of the peripheral blood lymphocyte-to-monocyte ratio (LMR) in various malignancies, including lymphoma. However, the prognostic value of the LMR in relapsed/refractory DLBCL has not been well evaluated. The purpose of the present study was to investigate whether the LMR at relapse can predict clinical outcomes for relapsed/refractory DLBCL patients treated with rituximab...

Cytauxzoon felis is a tick-borne hemoparasite that causes cytauxzoonosis in domestic cats in the United States. Historically, feline cytauxzoonosis was reported to be nearly always fatal. However, increasing evidence of cats surviving acute infection and/or harboring a chronic, subclinical infection has suggested the existence of different C. felis strains that may vary in pathogenicity. In this study, the intraspecific variation of the C. felis first and second ribosomal RNA internal transcribed spacer (ITS1, ITS2) regions was assessed for any clinical outcome or geographic associations...

Double-stranded RNA (dsRNA) is a common by-product of viral infections and acts as a potent trigger of antiviral immunity. In the nematode C. elegans, sid-1 encodes a dsRNA transporter that is highly conserved throughout animal evolution, but the physiological role of SID-1 and its orthologs remains unclear. Here, we show that the mammalian SID-1 ortholog, SIDT2, is required to transport internalized extracellular dsRNA from endocytic compartments into the cytoplasm for immune activation. Sidt2-deficient mice exposed to extracellular dsRNA, encephalomyocarditis virus (EMCV), and herpes simplex virus 1 (HSV-1) show impaired production of antiviral cytokines and-in the case of EMCV and HSV-1-reduced survival...

BACKGROUND: Common carotid artery and internal jugular vein are commonly cannulated for establishment of peripheral venoarterial extracorporeal membrane oxygenation (VA ECMO) support. We present our results of a vessel sparing cannulation technique for neck vessels, which helps maintain vessel patency after decannulation. METHODS: All patients who underwent ECMO, between January 2004 and January 2013 at a single center, were retrospectively reviewed. Follow up data for the patency of common carotid artery (CCA) and internal jugular vein (IJV) after decannulation were recorded...

Epithelial cells are essential to the survival and homeostasis of complex organisms. These cells cover the surfaces of all mucosae, the skin, and other compartmentalized structures essential to physiological function. In addition to maintenance of barriers that separate internal and external compartments, epithelia display a variety of organ-specific differentiated functions. Function is reflected in overall epithelial structure and organization, shape of individual cells, and proteins expressed by these cells...

Acute myeloid leukemia (AML) with the FLT3 internal tandem duplication (FLT3-ITD AML) accounts for 20-30% of AML cases. This subtype usually responds poorly to conventional therapies, and might become resistant to FLT3 tyrosine kinase inhibitors (TKIs) due to molecular bypass mechanisms. New therapeutic strategies focusing on resistance mechanisms are therefore urgently needed. Pim kinases are FLT3-ITD oncogenic targets that have been implicated in FLT3 TKI resistance. However, their precise biological function downstream of FLT3-ITD requires further investigation...

Pancreatic ductal adenocarcinoma (PDAC) is a very aggressive tumor with a five-year survival of less than 6%. Chronic pancreatitis (CP), an inflammatory process in of the pancreas, is a strong risk factor for PDAC. Several genetic polymorphisms have been discovered as susceptibility loci for both CP and PDAC. Since CP and PDAC share consistent number of epidemiologic risk factors, the aim of this study was to investigate whether specific CP risk loci also contribute to PDAC susceptibility. We selected five common SNPs (rs11988997, rs379742, rs10273639 rs2995271 and rs12688220) that were identified as susceptibility markers for CP and analyzed them in 2,914 PDAC cases, 356 CP cases and 5,596 controls retrospectively collected in the context of the international PANDoRA consortium...

There have been numerous investigations into the immunosuppressive effects of triptolide; however, its inhibitory effects on memory T cells remain to be elucidated. Using a cluster of differentiation (CD)4(+) memory T-cell transfer model, the aim of the present study was to determine the inhibitory effects of triptolide on CD4(+) memory T cell-mediated acute rejection and to determine the potential underlying mechanisms. At 4 weeks after skin transplantation, mouse cervical heart transplantation was performed following the transfer of CD4(+) memory T cells...

An animal's internal state is a critical parameter required for adaptation to a given environment. An important aspect of an animal's internal state is the energy state that is adjusted to the needs of an animal by energy homeostasis. Glucose is one essential source of energy, especially for the brain. A shortage of glucose therefore triggers a complex response to restore the animal's glucose supply. This counter-regulatory response to a glucose deficit includes metabolic responses like the mobilization of glucose from internal glucose stores and behavioral responses like increased foraging and a rapid intake of food...

Nearly one-third of patients with acute myeloid leukemia have FMS-Like Tyrosine Kinase 3 mutations and thus have poor survival prospects. Receptor tyrosine kinase Anexelekto is critical for FMS-Like Tyrosine Kinase 3 signaling and participates in FMS-Like Tyrosine Kinase 3 inhibitor resistance mechanisms. Thus, strategies targeting Anexelekto could prove useful for acute myeloid leukemia therapy. ONO-7475 is an inhibitor with high specificity for Anexelekto and MER Tyrosine Kinase. Here we report that ONO-7475 potently arrested growth and induced apoptosis in acute myeloid leukemia with internal tandem duplication mutation of FMS-Like Tyrosine Kinase 3...

PURPOSE: Bevacizumab, a humanized monoclonal antibody to VEGF, is used routinely in the treatment of patients with recurrent glioblastoma (GBM). However, very little is known regarding the effects of bevacizumab on the cells in the perivascular space in tumors. EXPERIMENTAL DESIGN: Established orthotopic xenograft and syngeneic models of GBM were used to determine entry of monoclonal anti-VEGF-A into, and uptake by cells in, the perivascular space. Based on the results, we examined CD133+ cells derived from GBM tumors in vitro...
