Reproducible long-term disc degeneration in a large animal model

STUDY DESIGN. Twelve goats were chemically degenerated and the development of the degenerative signs was followed for 26 weeks to evaluate the progression of the induced degeneration. The results were also compared with a previous study to determine the reproducibility. OBJECTIVES. The purpose of this study was determine whether this...

Long-term exposure to traffic-related air pollution and lung cancer risk

Background: Most studies on the association between lung cancer and air pollution have investigated mortality. There have been few studies of lung cancer incidence. Methods: We used data from the ongoing Netherlands Cohort Study on Diet and Cancer for 114,378 subjects with follow-up from September 1986 to December 1997. Exposure to black smoke,...

Therapeutic effects of Δ9-THC and modafinil in a marmoset Parkinson model

Current therapies for Parkinson's disease (PD) like l-dopa and dopamine (DA) agonists have declined efficacy after long term use. Therefore, research towards supplementary or alternative medication is needed. The implementation in PD can be expedited by application of compounds already used in the clinic. In this study the therapeutic effects of...

Ritonavir impairs lipoprotein lipase-mediated lipolysis and decreases uptake of fatty acids in adipose tissue

Objective - The use of the HIV protease inhibitor ritonavir (RTV) is frequently associated with hypertriglyceridemia and lipodystrophy. The aim of our study was to determine the mechanism underlying the observed hypertriglyceridemia. Methods and Results - Feeding female APOE*3-Leiden transgenic mice a Western-type diet supplemented with RTV (35...

Coeliac Disease: Background and biochemical aspects

Coeliac Disease has to be considered a main food related affliction, with life long consequences for the people having the disease. Coeliac Disease patients suffer from adverse effects that can be related to specific gluten peptide sequences that trigger a sequence of immune related reactions leading to damage of the intestine and related...

Alcohol consumption and risk of lung cancer: A pooled analysis of cohort studies

Background: Although smoking is the primary cause of lung cancer, much is unknown about lung cancer etiology, including risk determinants for nonsmokers and modifying factors for smokers. Objective: We hypothesized that alcohol consumption contributes to lung cancer risk. Design: We conducted a pooled analysis using standardized exposure and...

Beneficial effects of TCP on soman intoxication in guinea pigs: Seizures, brain damage and learning behaviour

Poisoning with the potent nerve agent soman produces a cascade of central nervous system (CNS) effects characterized by severe convulsions and eventually death. In animals that survive a soman intoxication, lesions in the amygdala, piriform cortex, hippocampus and thalamus can be observed. In order to examine the mechanisms involved in the...

Nutritional and psychological status of young women after a short-term use of a triphasic contraceptive steroid preparation

The present study was aimed to assess the psychological status of young healthy women after the administration of a triphasic contraceptive steroid preparation for six complete menstrual cycles. Subjects had never used oral contraceptives (OC) and had neither a familial history of depression nor psychological disturbances. OC-induced...

The rat incisor in toxicologic pathology

Microscopic examination of the incisors of rats and mice may reveal toxicologically significant changes. First, the incisor morphology reflects the nutritional status of the animal: fluctuations of mineral metabolism and vitamin availability are disclosed by the rodent incisors, because the incisors continue to grow during life. Similarly,...
