effects of one year treatment of sibutramine on insulin resistance parameters in type 2 diabetic patients

Purpose. Comparison of the effects of one year treatment with sibutramine compared to placebo on body weight, glycemic control, lipid profile, and insulin resistance parameters in type 2 diabetic patients. Methods. Two hundred and forty-six patients with uncontrolled type 2 diabetes mellitus in therapy with different oral hypoglycemic agents or insulin were enrolled in this study and randomised to take sibutramine 10 mg or placebo for one year. We evaluated at baseline, and after 3, 6, 9, and 12 months these parameters: body weight, body mass index (BMI), glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), post-prandial plasma glucose (PPG), fasting plasma insulin (FPI), homeostasis model assessment insulin resistance index (HOMA-IR), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (Tg), retinol binding protein-4 (RBP-4), resistin, visfatin, and high sensitivity-C reactive protein (Hs-CRP). Results. We observed a faster improvement of HbA1c, FPG and PPG with sibutramine compared to the control group; furthermore we recorded a decrease of FPI, TC, LDL-C, body weight, and BMI in the sibutramine group, but not in the control group. A faster decrease of HOMA-IR, resistin, and RBP-4 was recorded with sibutramine compared to the control group. We observed a significant decrease of Hs-CRP in both groups. Conclusions. Sibutramine gave a faster improvement of glycemic control, and of insulin resistance parameters compared to placebo; furthermore sibutramine gave also an improvement of lipid profile, and body weight

Comparison between orlistat plus l-carnitine and orlistat alone on inflammation parameters in obese diabetic patients

To evaluate the effects of 1-year treatment with orlistat plus L-carnitine compared to orlistat alone on body weight, glycemic and lipid control, and inflammatory parameters in obese type 2 diabetic patients. Two hundred and fifty-eight patients with uncontrolled type 2 diabetes mellitus (T2DM) [glycated hemoglobin (HbA(1c)) > 8.0%] in therapy with different oral hypoglycemic agents or insulin were enrolled in this study and randomized to take orlistat 120 mg three times a day plus L-carnitine 2 g one time a day or orlistat 120 mg three times a day. We evaluated the following parameters at baseline and after 3, 6, 9, and 12 months: body weight, body mass index (BMI), glycated hemoglobin (HbA(1c) ), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), fasting plasma insulin (FPI), homeostasis model assessment insulin resistance index (HOMA-IR), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (Tg), adiponectin (ADN), leptin, tumor necrosis factor-α (TNF-α), vaspin, and high-sensitivity C-reactive protein (Hs-CRP). We observed a better decrease in body weight, glycemic profile, HOMA-IR, LDL-C, and ADN and a faster improvement in FPI, TC, Tg, leptin, TNF-α, Hs-CRP with orlistat plus L-carnitine compared to orlistat alone. We also recorded an improvement in vaspin with orlistat plus l-carnitine not reached with orlistat alone. Orlistat plus L-carnitine gave a better improvement in body weight, glycemic and lipid profile compared to orlistat alone; furthermore, a faster and better improvement in inflammatory parameters was observed with orlistat plus L-carnitine compared to orlistat alone

An assessment of geologic sequestration potential in the panhandle of Florida USA

One alternative to reduce global greenhouse gas emissions is to store the emissions in underground geologic sequestration repositories. The efficacy of this approach has been favorably evaluated by numerous authors over the last 15 years. This paper discusses an assessment of the overall feasibility of storing emissions in three different repositories in the Florida panhandle located in the Southeastern United States. The feasibility assessment evaluates both saline aquifers and oil reservoirs located in the panhandle region. The overall feasibility is driven by the available geologic sequestration capacity, the transportation cost to deliver emissions to a respective repository, and other engineering and regulatory issues. The geologic sequestration capacity is generally controlled by the so-called storage efficiency, a variable dependent on the site-specific geology, reservoir conditions, and the injected fluid characteristics. For this paper, storage efficiency for saline repositories was assessed in more detail using numerical modeling. Based on the work completed, the 3 repositories studied have at least 4.55 gigatonnes of capacity to sequester CO2
