The energetics associated with the photoequilibrium (Formula: see text) are measured at 77 K by using pulsed-laser photocalorimetry and a range of excitation wavelengths and relative starting concentrations. Enthalpies for the photochemical transformations R hv----B and I hv----B are measured to be delta HRB = 32.2 +/- 0.9 kcal mol-1 and delta HIB = 27.1 +/- 3.2 kcal mol-1, respectively. Although the value of delta HRB is slightly lower than that reported previously by Cooper of 34.7 +/- 2.2 kcal mol-1 [Cooper, A. (1979) Nature (London) 282, 531-533], the two values are in agreement within experimental error. The energy difference delta HRB - delta HIB = 5.1 +/- 3.3 kcal mol-1 is identical within experimental error with the difference in enthalpies of isorhodopsin and rhodopsin [5.2 +/- 2.3; Cooper, A. (1979) FEBS Lett. 100, 382-384]. We suggest that this result is consistent with the theory that bathorhodopsin is a single, common photochemical intermediate connecting rhodopsin and isorhodopsin. 相似文献

Objective: High visceral adipose tissue (VAT) and high liver fat (LF) are associated with the metabolic syndrome and diabetes. We studied changes in these two fat depots during weight loss and analyzed whether VAT and LF at baseline predict the response to lifestyle intervention. Research Methods and Procedures: One hundred twelve subjects (48 men and 64 women; age, 46 ± 11 years; BMI, 29.2 ± 4.4 kg/m2) were studied after a follow up‐time of 264 ± 60 (SD) days. Insulin sensitivity was estimated from the oral glucose tolerance test. Body fat depots were quantified using magnetic resonance imaging and spectroscopy. Results: Cross‐sectionally high VAT (r = ?0.22, p = 0.02) and high LF (r = ?0.36, p < 0.0001) were independently associated with low insulin sensitivity. With intervention, BMI (?3.0%), VAT (?12.0%), and LF (?33.0%) were reduced (all p < 0.001). Insulin sensitivity was improved (+17%, p < 0.01). The changes in BMI (r = ?0.41), VAT (r = ?0.28), and LF (r = ?0.39) were associated with the increase in insulin sensitivity (all p < 0.01). High VAT (r = ?0.28, p = 0.01) and high LF (r = ?0.38, p < 0.01) at baseline were associated with a lesser increase in insulin sensitivity. Discussion: Baseline values and changes in BMI, VAT, and LF are related to changes in insulin sensitivity during lifestyle intervention. Subjects with high VAT and LF have a lower chance of profiting from lifestyle intervention and may require intensified lifestyle prevention strategies or even pharmacological approaches to improve insulin sensitivity. 相似文献

We aimed at determining which circulating forms of the adipokine adiponectin that increases lipid oxidation in liver and skeletal muscle are related to ectopic fat in these depots in humans. Plasma total‐, high‐molecular weight (HMW)‐, middle‐molecular weight (MMW)‐, and low‐molecular weight (LMW) adiponectin were quantified by an enzyme‐linked immunosorbent assay. Their relationships with liver‐ and intramyocellular fat, measured using 1H magnetic resonance spectroscopy, were investigated in 54 whites without type 2 diabetes. Liver fat, adjusted for gender, age, and total body fat, was associated only with HMW adiponectin (r = ?0.35, P = 0.012), but not with total‐, MMW‐, or LMW adiponectin. In addition, subjects with fatty liver (liver fat ≥5.56%, n = 15) had significantly lower HMW‐ (P = 0.04), but not total‐, MMW‐, or LMW adiponectin levels, compared to controls (n = 39). Similarly, intramyocellular fat correlated only with HMW (r = ?0.32, P = 0.039), but not with the other circulating forms of adiponectin. These data indicate that, among circulating forms of adiponectin, HMW is strongly related to ectopic fat, thus possibly representing the form of adiponectin regulating lipid oxidation in liver and skeletal muscle. 相似文献
