The portal appearance of enteral alpha-ketoglutarate (AKG) and the effect of enteral or parenteral AKG on portal net appearance of glucose, short-chain fatty acids, alanine, aspartate, glutamate, glutamine, proline and insulin were investigated in three growing pigs. During the experimental samplings the pigs were fed hourly with a standard feed mix with 5%(More)
Thionins are cysteine-rich, 5 kDa polypeptides which are toxic to plant pathogens in vitro. Expression of the gene encoding alpha-thionin from barley endosperm, under the 35S promoter from cauliflower mosaic virus, conferred to transgenic tobacco enhanced resistance to the bacterial plant pathogens Pseudomonas syringae pv. tabaci 153 and P. syringae pv.(More)
Extracts of saffron (Crocus sativus L.) have been reported to inhibit cell growth of human tumor cells. In order to study the cytotoxic effect of the characteristic compounds of saffron spice, we have isolated crocin, crocetin, picrocrocin and safranal. Doses inducing 50% cell growth inhibition (LD50) on HeLa cells were 2.3 mg/ml for an ethanolic extract of(More)
In the diagnosis of human brucellosis, PCR could be a more sensitive technique than blood cultures and more specific than conventional serological tests. We compared three different PCR methods for the detection of Brucella spp. and we studied whether human genomic DNA affect the sensitivity of three primer pairs for the detection of Brucella DNA in a(More)
This study investigates the association between the allelic distribution of two polymorphisms of the angiotensinogen (AGT) gene (T174M and M235T in the polypeptide chain) and blood pressure (BP) in a Mediterranean population in the south-west of Europe. The sample consists of 1322 participants from urban and rural areas, from the province of Albacete(More)
The objective of the present prospective, noncomparative, multicenter study was assess the safety and efficacy of gentamicin and doxycycline therapy for human brucellosis. In the first part of the study, a cohort of 17 patients received 100 mg of doxycycline (or 50 mg/kg of body weight per day if the body weight was < 40 kg) orally every 12 h for 45 days(More)
In order to test the hypothesis that Epstein-Barr virus (EBV) may be a cofactor for oral squamous cell carcinoma (OSCC) the authors evaluated tumour cells from OSCC of 108 patients without HIV infection, for the presence of EBV DNA by polymerase chain reaction. The sequences of oligonucleotides used in the amplification and hybridization included a set for(More)
Saffron corms have been demonstrated to contain a proteoglycan that inhibits growth of human tumor cells. In this study, we show strong evidence indicating that callus cultures of saffron corm also synthesize such glycoconjugate. This compound is cytotoxic against human cervical epithelioid carcinoma cells (IC50 = 7 mg ml-1), and consists of approximately(More)
BACKGROUND The purpose of this study was to validate a new level of consciousness monitor derived from the EEG, called the index of consciousness (IoC), by comparing it with the bispectral index (BIS) and the cerebral state index (CSI) during general anaesthesia for cardiac surgery using sevoflurane, remifentanil, and atracurium. METHODS After ethical(More)
We have read with interest the recent article by Morata et al. reporting their study of two of the possible factors which can interfere with specific DNA amplification in a peripheralblood PCR assay used for the diagnosis of human brucellosis (2). The study deals with the optimization of a method described in a previous work by these authors (4), in which(More)
