How a good sleep predicts life satisfaction: The role of zero-sum beliefs about happiness

Sleep, although a vital aspect of human functioning, has received scant attention in happiness research. This research examines the effect of sleep quality on life satisfaction, and one possible mechanism that bridges the two. One cognitive factor that might tie the relationship between sleep and life satisfaction is a belief about the (in) finite nature of happiness (zero-sum belief about happiness; ZBH), a mindset that occurs more under conditions of scarcity. Given the interconnections among experiences prompted by various types of scarcity (e.g., financial and calorie), we predicted that deprived cognitive resource caused by poor sleep may activate the ZBH, thereby hurting one’s life satisfaction. As expected, we found that sleep quality predicted the participants’ life satisfaction, even controlling for baseline variables. More importantly, this relationship was partially mediated by ZBH. This study opens interesting questions on a relatively unexamined role of non-social predictors, such as sleep, in well-being.11Yssciscopu

Endoscopic imaging and image-guided sampling for pancreatic neoplasia

Background: Endoscopic ultrasound (EUS) provides high-resolution images of the pancreas. There are two fundamental echoendoscope designs, yet no data support use of one type over the other. Once lesion is detected, EUS-guided fine-needle aspiration (FNA) is performed, but standard (STN) processing techniques can be associated with limited cellularity, leading to evaluation of novel filter-clot (FC) cellblock technique. With improved quality of EUS-FNA samples, it may be possible to pre-operatively evaluate biomarker status of pancreatic lesions to better risk stratify and tailor future treatments to individual patients. Aims: 1) To compare pancreatic lesion detection rates using radial and linear EUS and to determine incremental diagnostic yield of second EUS exam in tandem study. 2) To compare diagnostic yield and accuracy of STN and FC techniques of processing EUS-FNA samples. 3) To determine whether DPC4 gene status using EUS-FNA samples correlate with clinical outcomes in pancreatic cancer (PC) patients. Methods: High-risk individuals (HRIs) in screening program underwent radial or linear EUS or tandem radial and linear EUS in randomized order. Pancreatic lesion detection rates were compared. EUS-FNA samples during a 13-month period were used to compare the sample adequacy and diagnostic accuracy of STN and FC techniques. Retrospective review was performed evaluating whether Dpc4 immunolabeling status in EUS-FNA samples of PC patients correlated with pattern of disease progression and clinical outcomes. Results: In HRIs, linear EUS detected more pancreatic lesions than radial EUS. In tandem EUS exams, second EUS detected additional lesions, whether the initial exam was performed with radial or linear EUS. However, incremental detection rate was significantly higher if the second exam was linear EUS. FC technique had higher sample adequacy and diagnostic accuracy than STN technique. DPC4 status was associated with pattern of failure, with DPC4 negative PC more likely to progress with metastasis. Conclusion: Linear EUS should be the echoendoscope of choice in pancreatic imaging. FC technique was associated with improved quality of EUS-FNA samples. DPC4 status correlated with disease progression phenotypes in PC patients. Pre-operative biomarker studies using EUS-FNA samples have the potential to advance the concept of personalized medicine in the field of pancreatic oncology

First Confirmed Report of Powdery Mildew Caused by Erysiphe aquilegiae on Casuarina cunninghamiana in Argentina

Casuarina cunninghamiana Miq. (Fam. Casuarinaceae) is native to Australia and was introduced to Argentina and used as a windbreak, shade tree and for ornamental purposes. In autumn 2009, the potted seedlings in the nursery of La Plata University were found to be infected with a powdery mildew. Symptoms first appeared as thin white colonies, which subsequently developed into an abundant growth on the leaves and young stems. The damage caused by the powdery mildew infection has been observed every year after this initial infection and was again confirmed in April, 2011. There have been a few reports on the presence of powdery mildew on Casuarina spp. (Mantz et al., 2008; Farr and Rossman, 2011). In all the reports, the pathogen was cited to be Oidium sp. Thus, the aim of this work was to identify the causal agent of the powdery mildew observed on casuarina in Argentina

Radiofrequency Ablation of Thyroid Nodules: Basic Principles and Clinical Application

Radiofrequency (RF) ablation has been gaining popularity as a minimally invasive treatment for benign thyroid nodules regardless of the extent of the solid component. RF ablation of benign nodules demonstrated volume reductions of 33–58% after one month and 51–85% after six months, while solving nodule-related clinical problems. RF ablation has recently shown positive short-term results for locoregional control as well as symptom improvement in patients with recurrent thyroid cancers. This paper reviews the basic physics, indications, patient preparation, devices, procedures, clinical results, and complications of RF ablation

Silicon improves growth and antioxidative defense system in salt-stressed Kentucky bluegrass (Poa pratensis L.), ‘Perfection’ and ‘Midnight’

After 400 mM of NaCl treatment, 0.1 and 1.0 mM of silicon (Si) were added to Kentucky bluegrass, ‘Perfection’ and ‘Midnight,’ to identify the effect of Si on the antioxidant defense mechanisms and inorganic ions as a parameter in the salt stress on grass. Compared to the control, the NaCl treatment caused a significant decrease in the shoot length and the fresh and dry weight of shoot and root of the both types of Kentucky bluegrass. Adding Si after the NaCl treatment increased the growth and dry and fresh weight of shoot and root in the grass. In both types, the Na+ concentration significantly increased after the NaCl-only treatment compared to control and decreased dramatically after 0.1 and 1.0 mM Si were added following the NaCl treatment compared to the NaCl-only treatment. K+ and Si concentrations remarkably increased in the shoot and root when Si was added after NaCl treatment. There was a significant reduction in the oxygen radical absorption capacity and the total phenolic compounds in the both types. Compared to the NaCl-only treatment, higher glutathione and lower proline concentrations were observed in the plant treated with Si after NaCl treatment. These results suggest that, even though Si is not generally classified as ‘essential element’, Si may have a significant involvement in the antioxidant defense mechanisms and inorganic ions in the salt stress on grass.Key words: diphenyl-1-picrylhydrazyl (DPPH), total phenolic concentration, proline, salt stress

Effects of Non-verbal Priming on Attachment-Style Activation

Using an affective priming procedure, two experiments examined the effects of non-verbal cues on activating attachment styles. In Study 1, the secure attachment group, which was primed non-verbally, showed higher levels of self-esteem, interpersonal competence, and positive affect than the insecure attachment group, which was also primed non-verbally. In contrast, no significant difference was found between the two attachment groups that were primed verbally. In Study 2, using a different priming method and adding a neutral group, similar interactions between priming modality (non-verbal or verbal cues) and attachment styles were found: the differences in self-esteem, interpersonal competence, and positive affect between the secure attachment group, neutral group, and insecure attachment group were greater when primed non-verbally than when primed verbally. Finally, the limitations of the research and recommendations for follow-up study are discussed

We propose a macroscopic assessment system for investigating the characteristics of synovitis. Methods Fifty-four patients with a full-thickness rotator cuff tear undergoing arthroscopic rotator cuff repair with an average age of 62.5 ± 7.0 years were included. For the macroscopic assessment, 3 parameters, villous hypertrophy, hyperemia, and density, were measured and translated into grades in 3 regions-of-interest (ROI) in the glenohumeral joint and 4 ROIs in the subacromial space. For the microscopic assessments, 4 commonly used microscopic assessment systems were used. The reliability and association between the macroscopic and microscopic assessments were investigated. Results The inter- and intra-observer reliability of all of the macroscopic and microscopic assessments were excellent. The severity of synovitis was significantly greater in the glenohumeral joint than that in the subacromial space, 1.54 ± 0.61 versus 0.94 ± 0.56 (p < 0.001). Synovitis varied with respect to location, and was generally more severe near the tear with the macroscopic assessment system. Meanwhile, none of the microscopic assessment systems demonstrated differences between different ROIs in both the glenohumeral joint and the subacromial space. Conclusions The macroscopic assessment system for synovitis in rotator cuff disease in this study showed excellent reliability. It critically described characteristics of synovitis that microscopic assessment systems could not. Therefore, this system could be a useful tool for investigating synovitis in rotator cuff disease
