Past and current trends in soy supplementation: a bibliographic study.

The aim was to determine in what areas the therapeutic application of soy predominates in clinical trials and to assess the emerging fields of its use by means of an analysis of bibliographic resources. A search was performed in the MEDLINE database up to 31 december 2004, limited to the Title/Abstract field, and Clinical Trials as the type of publication. The abstracts from the publications selected (n=86) were reviewed and different variables were assessed.

Evaluation of immune markers in asymptomatic AIDS patients receiving fish oil supplementation.

The effects of oral fish oil (FO) supplementation (8 g/day, capsules) on nutritional status and selected immune markers (CD4/CD8 ratio, IL-1beta, erythrocyte MDA release, dehydroepiandrosterone sulfate [DHEA-S]) were studied in a homogeneous group of asymptomatic HIV-infected patients during 6 weeks. All subjects were classified clinically as A2 according to the CDC revised criteria (mean CD4 count 290 +/-123 cells/mm(3)) and were receiving zidovudine retroviral treatment. The calculated mean energy intake was 3437 +/- 372 Kcal/d, composed of 14% protein, 38% lipids and 48% carbohydrates, and was not modified during the study.

[Preoperative chemotherapy and total parenteral nutrition in colon cancer].

Aim: The objective of this study was to determine the effect of TPN after surgery in patients with colon carcinoma and preoperative chemotherapy.

Material And Method: The study included 27 patients, 16 men and 11 women, with a mean age of 62.1 +/- 11.

Dipeptidyl-peptidase IV in patients with short bowel syndrome.

Background & Aims: The aim of this study was to determine serum dipeptidyl peptidase IV (DPP IV) levels in a population of short bowel syndrome (SBS) patients, who had achieved intestinal adaptation.

Methods: DDP IV reference values were determined in a healthy population (n=47). The SBS study group consisted of 30 patients (17 men, 13 women; 53.

Influence of reagent formulation on mRNA quantification by RT-PCR using imported external standard curves.

Use of an imported external standard curve is common in real-time quantitative RT-PCR. Two practical strategies for long-term experiments include importing a grand mean standard curve to all accumulated runs or using daily imported standard curves, fixing the slope at the beginning of the experiment and calibrating successive runs with curves generated from this imported slope, adding a single standard that registers the variation in the y-intercept. This study determines the influence that a change in reagent lots has on these two calibration approaches when determining mRNA copy numbers of the ornithine decarboxylase and porphobilinogen deaminase genes.
