We report the angular diameters of two Mira variables (U Ari and Z Sco), three semi-regular and irregular variables (SW Vir, η Gem and µ Gem) and a supergiant semi-regular variable (TV Gem) by lunar occultation observations in the near-infrared broad K-band (2.2 µm). Lunar occultations of η Gem and µ Gem were also observed for the first time simultaneously in both K and L ′ bands yielding angul...
The direct conversion of diaryl ketones and enolizable aliphatic aldehydes into gem-difluoroalkenes has been a long-standing challenge in organofluorine chemistry. Herein, we report efficient strategies to tackle this problem by using difluoromethyl 2-pyridyl sulfone as a general gem-difluoroolefination reagent. The gem-difluoroolefination of diaryl ketones proceeds by acid-promoted Smiles rear...
The present work reports the use of non-living non-recombinant bacteria as a delivery system for mucosal vaccination. Antigens are bound to the cell-wall of pretreated Lactococcus lactis, designated as Gram-positive enhancer matrix (GEM), by means of a peptidoglycan binding domain. The influence of the GEM particles on the antigen-specific serum antibody response was studied. Following nasal im...
There are diverse experimental data about the influence of gemfibrozil (GEM) on the production of hydrogen peroxide (H(2)O(2)) and antioxidant enzymes. We investigated the influence of GEM treatment on the production of malondialdehyde (MDA) level in tissues of normolipidaemic Wistar and Fisher rats which is an index of lipid peroxidation. Because serum paraoxonase 1 (PON1) is an important enzy...
Gemcitabine (GEM) is the standard treatment for advanced/metastatic pancreatic cancer. However, there is a substantial subset of patients in whom the efficacy of GEM, when used as a single agent, is inadequate. Recently, the 5-fluorouracil (5-FU) prodrugs capecitabine and S-1 have been used as an alternative, either alone or in combination with GEM. The aim of the present study was to investiga...
BACKGROUND To explore the activity and tolerability of gemcitabine (GEM) and carboplatin (CBDCA) in non-small-cell lung cancer (NSCLC) we tested four administration sequences on H460 NSCLC cells, and at the same time performed a randomized phase II trial using analogous schedules. PATIENTS AND METHODS GEM was given first in two in vitro sequences, and CBDCA first in the other two; interaction...

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...
