Tumor associated antigens in human renal cell carcinoma: MHC restricted recognition by cytotoxic T lymphocytes.

1996

Based on previous studies in human melanoma leading to the molecular cloning of genes encoding peptide antigens recognized by MHC-restricted cytotoxic T lymphocytes (CTL) we extended our efforts to renal cancer systems established in tissue culture. In two patients we obtained stable CD8+ CTL clones with high cytolytic activity for the corresponding autologous tumor cell line in vitro. Neither autologous EBV-transformed B lymphocytes or PHA-activated PBL nor natural killer targets K562 were lysed by these CTL clones. MZ1257-RCC CTL5-30 lysed autologous tumor cells as well as normal kidney cell cultures in an HLA-A2 restricted fashion. Further specificity analysis showed cross reactivity wit…

Recovery of zinc from spent pickling solutions by liquid–liquid extraction using TBP

2019

In this paper, recovery of zinc from real spent pickling solutions by liquid–liquid extraction with tributyl phosphate (TBP) was studied. In particular, the effects of some parameters were investigated, such as the volume ratio between the organic phase and real spent pickling liquor (O/A) (1:2, 1:1, 2:1, 4:1), the stirring time (5–20–30 min) and the TBP concentration (10%–55%–100%), in order to determine the conditions leading to higher zinc extraction efficiency, as well as selectivity in relationships to other metals such as iron. After zinc extraction, TBP was successfully regenerated. Among several tested solutions, water allows zinc recovery higher than 90%, especially at 10% diluted …

Combined use of liquid chromatography triple quadrupole mass spectrometry and liquid chromatography quadrupole time-of-flight mass spectrometry in sy…

2012

As a suitable way for routine screening of pesticides and control of other organic contaminants in water, the combination of liquid chromatography triple quadrupole tandem mass spectrometry (LC-QqQ-MS/MS) and liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) has been applied to the analysis of 63 surface and waste water samples after conventional solid-phase extraction (SPE). The extracts were screened for 43 pesticides or degradation products by LC-QqQ-MS/MS achieving limits of detection (LOD) ranged from 0.04 to 2 ng L(-1). Of the 43 selected pesticides, 33 were detected in water samples. The ESI-QTOF MS instrument was run using two simultaneous acquisi…

Influence of Chronic Alcohol Intake on Intestinal Taurine and Antipyrine Transport in Pregnant Rats

1998

Taurine is a nonessential amino acid that plays a critical role in development. However, biosynthetic capacity is almost negligible in the fetus and must be supplied by the mother. Therefore, when maternal taurine status is depressed during gestation, fetal tissue taurine concentrations can also be compromised. In the present study, the effect of chronic alcohol intake on the intestinal transport of taurine during pregnancy has been investigated by an in vitro technique that allows measurement of the unidirectional influx of the amino acid across the intact rat mid jejunum. The influence of alcohol intake on the passive component of the intestinal transport was also investigated with antipy…

Experimental Studies on the Influence of Surfactants on Intestinal Absorption of Drugs Cefadroxil as model drug and sodium taurocholate as natural mo…

2011

The influence of the natural bile acid surfactant sodium taurocholate (CAS 81-24-3) on colic and duodenal (i.e. the proximal third of the small intestine) absorption of cefadroxil (CAS 50370-12-2) was studied using the in situ rat gut technique, and compared with the effect of sodium lauryl sulfate (CAS 151-21-3), the most widely used synthetic anionic surfactant. Previously, the stability, compatibility, and micelle-solubilization characteristics of taurocholate were assessed in order to correct, when necessary, the absorption results. White the passive absorption rate constants (kf, h-1) determined in colon in the presence of increasing lauryl sulfate concentrations showed an asymptotic v…

Especialidades contempladas en la legislación española respecto de la ejecución de la deuda tributaria en los delitos contra la Hacienda Pública

Este es el documento final publicado que se encuentra de forma definitiva en la siguiente URL: https://www.revista-rbd.com/wp-content/uploads/2020/02/12._Antonio_Ferrer_pp._370-391.pdf En el tratamiento del delito fiscal, el procedimiento penal podía determinar la paralización de cualquier acción de la Hacienda Pública en orden al cobro de la deuda tributaria, lo que al margen de generar la idea errónea de que esta deuda se integraba estrictamente en el ámbito de la responsabilidad civil derivada del delito, dificultaba su ejecución determinando un importante agravio comparativo respecto al mero infractor, e incluso frente a un deudor ordinario, adoptándose por ello en nuestra legislación u…

Volume III. DUNE far detector technical coordination

2020

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay-these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the st…
