Combination of pneumatic lithotripsy and transurethral prostatectomy in bladder stones with benign prostatic hyperplasia

There are numerous reported cases of lingual thyroid with an obvious prevalence in pediatric age. Such ectopic thyroid glands are probably quantitatively deficient and thyroid function may be low or at a low normal level. Apparently, most cases of ectopic thyroid tissue develop congenital hypothyroidism, the so-called cretinism. In this report, we describe a very rare adult male case of lingual thyroid who developed hypothyroidism in adulthood; the anomaly remained undiscovered, being without local common symptoms, and permitted a normal life.     

Sertraline in the treatment of premature ejaculation: a double-blind placebo controlled study

Twelve children with obstetric paralysis were diagnosed as having a posterior dislocation of the humeral head. The diagnosis was suspected on clinical grounds and confirmed by computed tomography (CT) scans in all cases. All 12 patients were treated with open reduction via an anterior approach. The age range at the time of surgery was from 7 months to 7 years (average, 2 years and 3 months). All patients were immobilized in a shoulder spica for 6 weeks and a further 6 weeks in an orthosis. All patients were examined by CT scans in the postoperative period, which confirmed a satisfactory reduction in all cases. With a minimal follow-up of 12 months, there have been no redislocations. This article demonstrates that dislocation of the shoulder in association with obstetric paralysis is not rare, as previously described, and shows that once diagnosed, the dislocation can be satisfactorily treated by a single anterior open reduction of the shoulder.     

The influence of positive affect on the components of expectancy motivation.

The influence of positive affect on expectancy motivation was investigated in 2 studies. The results of Study 1 indicated that positive affect improved people's performance and affected their perceptions of expectancy and valence. In Study 1, in which outcomes depended on chance, positive affect did not influence people's perceptions of instrumentality. In Study 2, in which the link between performance and outcomes was specified, positive affect influenced all 3 components of expectancy motivation. Together, the results of Studies 1 and 2 indicated that positive affect interacts with task conditions in influencing motivation and that its influence on motivation occurs not through general effects, such as response bias or general activation, but rather through its influence on the cognitive processes involved in motivation.

Positive affect facilitates creative problem solving.

Four experiments indicated that positive affect, induced by means of seeing a few minutes of a comedy film or by means of receiving a small bag of candy, improved performance on two tasks that are generally regarded as requiring creative ingenuity: Duncker's (1945) candle task and M. T. Mednick, S. A. Mednick, and E. V. Mednick's (1964) Remote Associates Test. One condition in which negative affect was induced and two in which subjects engaged in physical exercise (intended to represent affectless arousal) failed to produce comparable improvements in creative performance. The influence of positive affect on creativity was discussed in terms of a broader theory of the impact of positive affect on cognitive organization.

Novel Polymer-Bentonite Sorbent for Recovery of Antioxidant Polyphenols from Cornus mas L. through Integrated Process Extraction/Adsorption: Optimization of Extraction Parameters by Response Surface Methodology

Here, ultrasound-assisted extraction with ultrasonic probe of total polyphenolic content from leaves of cornelian cherry (Cornus mas L.) was studied. Batch adsorption was carried out to concentrate polyphenol extract using bentonite/2-(dimethyl amino) ethyl methacrylate composite adsorbent. The extraction was optimized through face central composite design combined with response surface methodology. It was found that bentonite/2-(dimethyl amino) ethyl methacrylate composite exhibits significant adsorption capacity (2407.50 mg-GAE/g-bentonite/2-(dimethyl amino) ethyl methacrylate composite) for polyphenols in cornelian cherry leaves. It was observed that pH was the crucial factor and highest adsorption capacity was obtained at pH 10.     

Predicting behavior in economic games by looking through the eyes of the players.

Social scientists often rely on economic experiments such as ultimatum and dictator games to understand human cooperation. Systematic deviations from economic predictions have inspired broader conceptions of self-interest that incorporate concerns for fairness. Yet no framework can describe all of the major results. We take a different approach by asking players directly about their self-interest—defined as what they want to do (pleasure-maximizing options). We also ask players directly about their sense of fairness—defined as what they think they ought to do (fairness-maximizing options). Player-defined measures of self-interest and fairness predict (a) the majority of ultimatum-game and dictator-game offers, (b) ultimatum-game rejections, (c) exiting behavior (i.e., escaping social expectations to cooperate) in the dictator game, and (d) who cooperates more after a positive mood induction. Adopting the players' perspectives of self-interest and fairness permits better predictions about who cooperates, why they cooperate, and when they punish noncooperators.
