Metastatic Ureteral Involvement of Non-Small Cell Lung Cancer
Metastases from a variety of malignant tumors can involve the ureters, but ureteral involvement by lung cancer is extremely rare and usually described at autopsy. We report a rare case of a 76-year-old man who presented with a three-month history of right flank dullness and was noted to have a nonhomogeneous retroperitoneal mass with hydronephrosis of the right kidney on computed tomography of the abdomen. Computed tomography of the thorax showed a nodule in the lower lobe, measuring 3 × 2 cm, in the right lung. After excluding the presence of other primary tumors and metastases, we reached a final diagnosis of solitary retroperitoneal metastasis of adenocarcinoma of the lung. Although rare, in patients of non-small cell lung cancer, presence of hydronephrosis should alert the physician to the possibility of metastasis

Antiferromagnetic order driven by the molecular orbital order of C in --tetra----(dimethylamino)--ethylene--C
We have studied the ground state of a fullerene--based magnet, the
--phase tetra----(dimethylamino)--ethylene--C
(--TDAE--C), by electron spin resonance (ESR) and magnetic
torque measurements. Below T K, non--paramagnetic field dependent
resonances with a finite excitation gap (1.7 GHz) are observed along the
--axis. Strong enhancement in their intensity as temperature is decreased is
inconsistent with excitation from a singlet state, which had been proposed for
the --phase ground state. Below T, non--quadratic field dependence
of magnetic torque signal is also observed in contrast to quadratic field
dependence in the paramagnetic phase. The angle--dependent torque signals below
T indicate the existence of an anisotropy of the bulk magnetization. From
both experiments, we propose an antiferromagnetic ground state driven by the
cooperative orientational ordering of C in the
--TDAE--C.Comment: 4 pages, 3 figure

Successful Endoscopic Management of Fish Bone Embedded into the Bladder Wall
We report a case of a pyogenous vesical abscess resulting from an ingested fish bone embedded in the bladder wall that was treated endoscopically in an asymptomatic man. Computed tomography of the abdomen showed a linear radiopaque structure in the thickened left anterolateral wall of the bladder. Cystoscopy revealed a protruding mass, covered with normal-appearing mucosa, with outflow of pus from a shallow recess. Histopathological findings indicated that the transurethrally removed linear structure, located in the submucosa, was compatible with fish bone. A high index of suspicion should be maintained for the correct diagnosis to be made
Effects of Sulfur Amino Acids on Tyrosyl or Serine/Threonine Phosphorylation and Translocation of Cytosolic Compounds to Cell Membrane in Stimulus-treated Human Neutrophils
We investigated the effects of various sulfur amino acids on the phosphorylation of proteins and the translocation of cytosolic compounds to cell membrane in stimulus-treated human neutrophils using specific monoclonal antibodies. D,L-homocysteine and D,L-homocysteine-thiolactone enhanced fMLP-induced tyrosyl phosphorylation of proteins and the translocation of p47phox, p67phox, and rac to the cell membrane in a concentration-dependent manner. L-cystathionine, NAc-L-cysteine and carboxymethylcysteine suppressed the tyrosyl phophorylation and translocation of cytosolic compounds to the cell membrane. L-cystathionine, L-cysteine and NAc-L-cysteine suppressed PMA-induced serine/threonine phosphorylation and the translocation of cytosolic compounds to the cell membrane. L-cysteine, NAc-L-cysteine and D,L-homocysteine enhanced AA-induced serine/threonine phosphorylation and the translocation of cytosolic compounds to the cell membrane, but L-cystathionine had opposite effects. These results indicated that the effects of sulfur amino acids on tyrosyl or serine/threonine phosphorylation and the translocation of p47phox, p67phox, and rac to the cell membrane in the stimulus-treated human neutrophils were in parallel with those of the stimulus-induced superoxide generation reported in previous paper. L-cysteine, D,L-homocysteine and L-cystathionine weakly inhibited lipid peroxidation, but the other sulfur amino acids tested had no effect.</p
Study of hadron interactions in a lead-emulsion target
Topological and kinematical characteristics of hadron interactions have been
studied using a lead-emulsion target exposed to 2, 4 and 10 GeV/c hadron beams.
A total length of 60 m tracks was followed using a high speed automated
emulsion scanning system. A total of 318 hadron interaction vertices and their
secondary charged particle tracks were reconstructed. Measurement results of
interaction lengths, charged particle multiplicity, emission angles and momenta
of secondary charged particles are compared with a Monte Carlo simulation and
appear to be consistent. Nuclear fragments emitted from interaction vertices
were also detected by a newly developed emulsion scanning system with
wide-angle acceptance. Their emission angle distributions are in good agreement
with the simulated distributions. Probabilities of an event being associated
with at least one fragment track are found to be greater than 50% for beam
momentum GeV/c and are well reproduced by the simulation. These
experimental results validate estimation of the background due to hadron
interactions in the sample of decay candidates in the OPERA oscillation experiment.Comment: 14 pages, 11 figure
