Plasma lipid levels and lipoprotein lipase (LPL) are known to follow circadian rhythms in rats. However, very little information is available on the variations in respiratory quotient (RQ) during the 24-h period in rats. The aims of this study were to provide an overall view of the effects of circadian rhythm on RQ and to determine the relationship of LPL and RQ with metabolic parameters in the...

LKB1 complexed with MO25 and STRAD has been identified as an AMP-activated protein kinase kinase (AMPKK). We measured relative LKB1 protein abundance and AMPKK activity in liver (LV), heart (HT), soleus (SO), red quadriceps (RQ), and white quadriceps (WQ) from sedentary and endurance-trained rats. We examined trained RQ for altered levels of MO25 protein and LKB1, STRAD, and MO25 mRNA. LKB1 pro...

PURPOSE The respiratory quotient (RQ) is useful for evaluating glucose and lipid metabolism in vivo. We previously reported that the RQ value, even after fasting, was high in diabetics being treated with sulphonylurea (SU), which might explain the accumulation of fat, leading to weight gain in such individuals. In the present study, we measured the RQ in type II diabetic patients who were being...

Photosynthesis and respiration are major components of the plant carbon balance. During stress, like drought, carbohydrate supply from photosynthesis is reduced and the Krebs cycle respiration must be fueled with other stored carbon compounds. However, the dynamics of storage use are still unknown. The respiratory quotient (RQ, CO2 released per O2 consumed during respiration) is an excellent in...

BACKGROUND High-risk individuals for CHD could be diagnosed by some non-invasive and low-priced techniques such as Minnesota ECG coding and rose angina questionnaire (RQ). OBJECTIVES The present study aimed at determining the risk of incident CHD according to ECG and RQ besides diabetes and other metabolic risk factors in our population. METHODS Participants comprised of 5431 individuals ag...

utilization patterns (Dilly, 2001), the microbial community structure (e.g., proportions of bacteria to fungi) The barometric process separation (BaPS) and 15N dilution tech(Klein, 1977) and abiotic factors such as soil moisture– niques were used to determine gross nitrification rates on the same soil cores from an old grassland soil. The BaPS-technique separates temperature relationships (Klei...

Let f : M → N be a Cr map between Cr manifolds (r ≥ 1) and K a Cr manifold. In this paper, by using the Sard theorem, we study the topological properties of the space of Cr maps g : K → N which satisfy a certain transversality condition with respect to f in a weak sense. As an application, by considering the case where K is a point, we obtain some new results about the topological properties of...
