Behavioral treatment approaches to obesity in 17 mild-to-moderate retarded female adults were assigned to one of two experimental conditions, (a) behavioral self-control along with a physical activity component and (b) behavioral self-control. No significant differences were noted between groups on the indices of body weight and tricep skinfold thickness. A one-way analysis of variance with a repeated measure yielded a significant main effect of time for change in weight for both groups at the end of the 8-week treatment. Questions were raised about the possible role of nonspecific motivational factors versus cognitive factors in behavioral-weight reduction programs.

Abstract Molecular weight reduction of natural rubber (NR) with hydrogen peroxide (H2O2) oxidizing agent is limited in biphasic water-toluene systems that is attributed to mass transfer. In this work, CO2 was applied to the (aqueous H2O2)-(toluene-NR) systems with the objective of improving reaction efficiency. Experiments were performed on the reaction system with CO2 at 12 MPa and at reaction temperatures and times of 60°C–80°C and 1 h–10 h to evaluate the reaction kinetics. CO2 could enhance the NR molecular weight reduction by lowering the activation energy (from 121 kJ·mol−1 to 38 kJ·mol−1). The role of CO2 in the reaction system seems to be the formation of oxidative peroxycarbonic acid intermediate and promotion of mass transport due to the reduction in the toluene-NR viscosity and interfacial tension. The epoxidized liquid NRs (M̅n=4.9×103 g·mol−1) obtained from NR molecular weight reduction was further processed to prepare hydroxyl telechelic NR (M̅n=1.0×103 g·mol−1) and biobased polyurethane.

The intragastric balloon (IGB) has been used for decades as a temporary measure for weight reduction in the morbidly obese. Serious complications related to the device remain rare. We present the case of a 23-year-old Caucasian man who developed signs of bowel obstruction following spontaneous partial deflation of an air filled IGB with subsequent migration and impaction in the jejunum. We discuss the role of the IGB in the treatment of obesity, side effects and the serious complications that can occur.
