Abstract. This paper considers gauge-invariant and covariant gravitational perturbations on arbitrary vacuum locally rotationally symmetric (LRS) class II space-times. Ultimately, we derive four decoupled equations governing four specific combinations of the gravito-electromagnetic (GEM) 2-tensor harmonic amplitudes. We use the gauge-invariant and covariant 1+1+2 formalism which Clarkson and Ba...
Tuberculosis (TB), caused by Mycobacterium tuberculosis, remains a major human pandemic. Germline-encoded mycolyl lipid-reactive (GEM) T cells are donor-unrestricted and recognize CD1b-presented mycobacterial mycolates. However, the molecular requirements governing mycolate antigenicity for the GEM T cell receptor (TCR) remain poorly understood. Here, we demonstrate CD1b expression in TB granul...
BACKGROUND We have recently completed a large phase III trial in advanced non-small cell lung cancer (NSCLC) in the elderly which showed that the combination of gemcitabine (GEM) plus vinorelbine (VNR), with GEM administered first, did not improve any outcome as compared with each single drug. MATERIALS AND METHODS The anti-tumor efficacy of different sequences of administration of GEM and VN...
Among the most effective strategies for changing the process and outcomes of clinical care are those that make use of computer-mediated decision support. A variety of representation models that facilitate computer-based implementation of medical knowledge have been published, including the Guideline Elements Model (GEM) and the Arden Syntax for Medical Logic Modules (MLMs). We describe an XML-b...
A graph is (P5,gem)-free, when it does not contain P5 (an induced path with five vertices) or a gem (a graph formed by making an universal vertex adjacent to each of the four vertices of the induced path P4) as an induced subgraph. We present O(n2) time recognition algorithms for chordal gem-free and for (P5,gem)free graphs. Using a characterization of (P5,gem)-free graphs by their prime graphs...
The initiation of postembryonic cell divisions by the gonadal precursors of C. elegans requires the activity of gon-2. gon-2 encodes a predicted cation channel (GON-2) of the TRPM subfamily of TRP proteins and is likely to mediate the influx of Ca(2+) and/or Mg(2+). We report here that mutations in gem-4 (gon-2 extragenic modifier) are capable of suppressing loss-of-function alleles of gon-2. g...
Biliary tract cancer (BTC) is the second common cancer in liver cancer. Chemotherapy is the mainstay of treatments for patients with advanced or metastatic disease, while fluorouracil (FU)-based and gemcitabine (GEM)-based treatments are most widely applied. This NMA aimed to figure out whether the addition of platinum (PLA) and target agents (TAR) can influence the efficacy and safety of stand...
GEM (glycosphingolipid-enriched microdomains) are specialized detergent-resistant domains of the plasma membrane in which some gangliosides concentrate. Although genesis of GEM is considered to occur in the Golgi complex, where the synthesis of gangliosides also occurs, the issue concerning the incorporation of ganglioside species into GEM is still poorly understood. In this work, using Chinese...
Gemcitabine (GEM) is the front-line standard chemotherapy used for the treatment of pancreatic cancer; however, chemoresistance to GEM remains the major obstacle to the successful control of this disease. Both the expression levels and activity of aldehyde dehydrogenase 1A1 (ALDH1A1) are important features of tumor-initiating and/or cancer stem cell properties in multiple types of human cancer....
Hypoxia-inducible factor 1α (HIF1α) has emerged as a promising new target for pancreatic cancer treatment over the past decade. High expression of HIF-1α increases the drug resistance of the current first line chemotherapeutic drug, gemcitabine (Gem). Here we employed biocompatible lipid-polymer hybrid nanoparticles to co-deliver HIF1α siRNA (si-HIF1α) and Gem for pancreatic cancer treatment in...
