Functional MRI of rat brain was performed at 2 Tesla following intravenous injection of cocaine in order to 1) determine if changes in CBV and changes in BOLD signal were regionally coupled in brain parenchyma, and 2) compare the sensitivities of these imaging methods across different brain structures. Percent changes in CBV and BOLD relaxation rate were spatially and temporally coupled during ...
Induction of liver cancer by peroxisome proliferators such as nafenopin is frequently associated with increased liver growth, increased DNA synthesis and suppression of apoptosis. The cytokine, tumour necrosis factor alpha (TNF alpha), and non-parenchymal liver cells have been implicated in mediating the hepatic response to peroxisome proliferators. Here, we have investigated the dependency of ...
The awareness that sarcoidosis can involve intrathoracic lymph nodes and lung parenchyma in sequential fashion evolved during the first half of this century. This awareness resulted in a roentgenographic staging system that has relevance to the course and prognosis, pulmonary function changes, and the symptom of dyspnea. The following definition or roentgenographic staging is proposed as the si...
BACKGROUND Pancreatic destruction affects the majority of patients with cystic fibrosis. We aimed to relate ultrasound findings to exocrine pancreatic function and cystic fibrosis genotype. METHODS Patients with cystic fibrosis and a matched group of healthy controls were included. We performed transabdominal ultrasound, and recorded echo intensities of the pancreas and parenchymal characteri...
Functional brain-imaging techniques used in humans and animals, such as functional MRI and intrinsic optical signal (IOS) imaging, are thought to largely rely on neurovascular coupling and hemodynamic responses. Here, taking advantage of the well-described micro-architecture of the mouse olfactory bulb, we dissected the nature of odor-evoked IOSs. Using in vivo pharmacology in transgenic mouse ...
Farmer, C. and Palin M.-F. 2008. Feeding flaxseed to sows during late-gestation and lactation affects mammary development but not mammary expression of selected genes in their offspring. Can. J. Anim. Sci. 88: 585 590. Mammary gland composition and mammary gene expression were measured in pubertal gilts whose dam were fed a control (CTL) diet or a diet with a 10% supplement of flaxseed (FS) dur...
Background: Recently, it has been proposed that different clinical phenotypes can be recognized in patients with chronic obstructive disease (COPD), namely predominant airway disease or parenchymal destructive changes. Objectives: The aim of this prospective multicenter study was to evaluate whether these two phenotypes may influence outcomes following a pulmonary rehabilitation program (PRP). ...
