OBJECTIVE To study the validity of quantitative cultures of tracheal aspirate (TA) in comparison with the plugged telescoping catheter (PTC) for the diagnosis of mechanical ventilator-associated pneumonia. METHOD Prospective multicenter study enrolling patients undergoing mechanical ventilation for longer than 72 hours. TA samples were collected from patients with suspected ventilator-associa...

Two Gram-negative, non-motile, non-spore-forming and moderately halophilic cocci (strains YKJ-103T and YKJ-105) were isolated from the traditional Korean fermented seafood, jeotgal. The two strains grew optimally at 25-30 degrees C and grew at 4 and 36 degrees C, but not above 37 degrees C. They grew in the presence of 0-10% (w/v) NaCl with an optimum of 2-3% (w/v) NaCl. Strains YKJ-103T and YK...

Colorectal carcinomas (CRCs) with high-level microsatellite instability (MSI-H) often contain gene fusions, which involve receptor tyrosine kinases. This study included 105 MSI-H CRCs. NTRK1/2/3, ALK, ROS1 and RET fusions were analyzed by PCR test for 5’/3’-end unbalanced expression, is capable of detecting all translocation variants. The type rearrangements was subsequently determined variant-...

Manoussakis, Y. and D. Amar, Hamiltonian paths and cycles, number of arcs and independence number in digraphs, Discrete Mathematics 105 (1992) 157-172. We let D denote a digraph with n vertices, independence number at least (Y and half-degrees at least k. We give (i) a function f(n, a) (respectively f (n, k, a)) such that any digraph with at least f(n, a) (respectively f(n, k, a)) arcs is Hamil...

Trichothecene mycotoxins such as deoxynivalenol (DON) are known to modulate the immune function, but to this date only few studies have been conducted with farm animals, especially pigs, which are regarded as most susceptible to this mycotoxin. Mitogen-stimulated proliferation of porcine blood lympho­ cytes was measured using two different assays, the MTT cleav­ age (metabolic activity) and the...

Monoclonal (MAb 362.50) and polyclonal (anti-gpl05-2) antibodies have been used to examine the expression by transplantable (II 1C) and primary (PI 1C) hepatocellular carcinomas of a 105 kd rat hepatocyte cell adhesion molecule designated cell-CAM 105. Two-dimensional gel analy sis of components immunoprecipitated with MAb 362.50 or anti-gpl052 antibodies from detergent extracts of cells surfac...
