An experimental model has been developed to quantify some of the major processes initiated by tumor transplanta tion and culminating in pulmonary métastases.The T241 fibrosarcoma, chosen because of its high hematogenous metastatic propensity and reproducible biological behavior, is transplanted into the femoral region of the C57BL mouse. Experiments are performed at specified times after trans...

Abstract We give some adequate extension, in the framework of a general Lévy process, of our previous construction of processes with one-dimensional martingale marginals, done originally in the set-up of Brownian motion. The Lévy process framework allows us to streamline our previous arguments, as well as to reach a larger class of such processes, even in the Brownian case. We give some illustr...

Recent developments in phosphorus (P) removal have focused on P reactive materials to use within constructed wetlands (CW), as a sustainable alternative to chemical dosing. In this study, different fractions of Basic Oxygen Furnace (BOF) steel slag and apatite media have been tested in full-scale CWs, being the first trial of its kind in the United Kingdom evaluating the P removal capacity of b...

Piggery effluent may contribute to the eutrophication of waterways, if it is not treated before disposal, because of high levels of phosphorus. Limes and red muds (a residue from bauxite refining) were used to remove phosphorus from piggery effluent (41 mg litre(-1) total P). Lime-based amendments were more effective than the red muds at removing phosphorus when compared at the same liquid: sol...

The physicochemical qualities of a refinery effluent and water and sediment of an effluent receiving water body were investigated. The treated refinery effluent contained very high concentrations of phenol (11.06 mg/l), oil and grease (7.52 mg/l), ammonia (8.52 mg/l), COD (91.76 mg/l), TDS (390.6 mg/l) and phosphate (6.2 mg/l), but low in sulphide, nickel, lead, copper and chromium, which were ...

1. In anaesthetized patients under controlled respiration, samples of lumbar cerebrospinal fluid were withdrawn 15 and 60 min after an intravenous injection of 30 mg tubocurarine. When tested on the frog rectus muscle preparation contracted by acetylcholine, they exerted curare-like activity which corresponded to between 0.05 and 0.33 mug/ml tubocurarine.2. In dogs anaesthetized with pentobarbi...

High mobility group box 1 (HMGB1) is a nuclear transcription factor. Once HMGB1 is released by damaged cells or activated immune cells, it acts as danger molecule and triggers the inflammatory signaling cascade. Currently, evidence is accumulating that posttranslational modifications such as oxidation may modulate the pro-inflammatory potential of danger signals. We hypothesized that oxidation ...

To produce ginsenoside-Rg3 enriched yeast from ginseng-steaming effluent (GSE), Lipomyces starkeyi, which tends to grow well in GSE, was cultured in sterilized GSE and its growth and production of ginsenoside-Rg3 were determined. Growth of L. starkeyi was 86.1 mg per g GSE and its ginsenoside-Rg3 contents was 0.013 mg per g GSE.

This paper investigated the effect of mixed cultures of Pseudomonas aureofaciens and Escherichia coli and air as gas on degradation of chemical oxygen demand (COD) in three-phase inverse fluidized beds (TPIFBs) for textile effluents with initial COD of 1200 ppm (effluent 1) and 640 ppm (effluent 2). Investigators focused on the importance of different design of gas spargers of the TPIFB for che...
