The present study examines whether the use of humor in scientific article titles is associated with the number of citations an article receives. Four judges rated the degree of amusement and pleasantness of titles of articles published over 10 years (from 1985 to 1994) in two of the most prestigious journals in psychology, Psychological Bulletin and Psychological Review. We then examined the association between the levels of amusement and pleasantness and the article's monthly citation average. The results show that, while the pleasantness rating was weakly associated with the number of citations, articles with highly amusing titles (2 standard deviations above average) received fewer citations. The negative association between amusing titles and subsequent citations cannot be attributed to differences in the title length and pleasantness, number of authors, year of publication, and article type (regular article vs comment). These findings are discussed in the context of the importance of titles for signalling an article's content.

Citrus juices lose their typical aroma shortly afer extraction. Presence of oxygen is known to affect the flavor of heat processed citrus juices. The effect of enzymatic deoxygenation, with glucose oxidase-catalase preparations immediately afer juice extraction on kinetics of oxygen removal and on quality of fresh and pasteurized orange juice was investigated.Enzyme preparations reduced dissolved oxygen in fresh orange juice to less than 1 ppm in about 30 min at room temperature. In fresh juices microbial growth was delayed and shelf-life of these juices was increased. In pasteurized juices no improvement was observed.

Background: Radical cystectomy (RC) is the standard treatment for muscle invasive bladder cancer (MIBC). Neoadjuvant chemotherapy (NAC) is associated with improved patient survival. The impact of NAC on nutritional status is understudied, while the association between malnutrition and poor surgical outcomes is well known. This study aims to examine the association between NAC, nutritional status impairment, and post-operative morbidity. Materials and Methods: We included MIBC patients who underwent RC and received NAC from multiple academic centers in Israel. Cross-sectional imaging was used to measure the psoas muscle area and normalized it by height (smooth muscle index, SMI). Pre- and post-NAC SMI difference was calculated (represents nutritional status change). The primary outcomes were post-RC ileus, infection, and a composite outcome of any complication. Logistic regression models were fit to identify independent predictors of the outcomes. Results: Ninety-one patients were included in the study. The median SMI change was −0.71 (−1.58, −0.06) cm2/m2. SMI decline was significantly higher in patients with post-RC complications (−18 vs. −203, p < 0.001). SMI change was an independent predictor of all complications, ileus, infection, and other complications. The accuracy of SMI change for predicting all complications, ileus, infection, and other complications was 0.85, 0.87, 0.75, and 0.86, respectively. Conclusions: NAC-related nutritional deterioration is associated with increased risk of complications after RC. Our results hint towards the need for nutritional intervention during NAC prior to RC.
