Effects of cashew nut consumption on body composition and glycemic indices: A meta-analysis and systematic review of randomized controlled trials

Background and aimsPresent meta-analysis and systematic review was conducted to synthesis a definitive conclusion from previous randomized controlled clinical trials (RCTs).MethodsA comprehensive search was done up to July 2020, in order to extract RCTs which investigated the effect of cashew nut on weight, body mass index (BMI), waist circumference (WC), fasting blood sugar (FBS), insulin, and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Weighted mean difference (WMD) and 95% confidence interval (CI) were used to estimate effect size. Meta regression analysis was done to identify probable sources of heterogeneity.ResultsSix clinical trials with 521 participants were included. Combined effect sizes demonstrated no effect of cashew consumption on weight (WMD): 0.02, 95% CI: ?1.04, 1.09, P > 0.05), BMI (WMD: 0.1, 95% CI: ?0.72, 0.74, P > 0.05), and WC (WMD: ?0.13, 95% CI: ?1.97, 1.70, P > 0.05). Results were also not significant for FBS (WMD: 3.58, 95% CI: ?3.92, 11.08, P > 0.05), insulin (WMD: ?0.19, 95% CI: ?1.63, 1.25, P > 0.05), and HOMA-IR (WMD: 0.25, 95% CI: ?0.55, 1.06, P > 0.05).ConclusionThe sum up, incorporating cashew into the diet has no significant effect on body composition or modifying glycemic indices.     

Synergistic Effects of Pr6O11 and Co3O4 on Electrical and Microstructure Features of ZnO-BaTiO3 Varistor Ceramics

This paper investigated the effects of Pr₆O₁₁ and Co₃O₄ on the electrical properties of ZnO-BaTiO₃ varistor ceramics. The Pr₆O₁₁ doping has a notable influence on the characteristics of the nonlinear coefficient, varistor voltage, and leakage current where the values varied from 2.29 to 2.69, 12.36 to 68.36 V/mm and 599.33 to 548.16 µA/cm², respectively. The nonlinear varistor coefficient of 5.50 to 7.15 and the varistor voltage of 7.38 to 8.10 V/mm was also influenced by the use of Co₃O₄ as a dopant. When the amount of Co₃O₄ was above 0.5 wt.%, the leakage current increased from 202.41 to 302.71 μA/cm². The varistor ceramics with 1.5 wt.% Pr₆O₁₁ shows good nonlinear electrical performance at higher breakdown voltage and reduced the leakage current of the ceramic materials. Besides, the varistor sample that was doped with 0.5 wt.% Co₃O₄ was able to enhance the nonlinear electrical properties at low breakdown voltage with a smaller value of leakage current.     

Dentin Phosphophoryn-Derived Peptide Promotes Odontoblast Differentiation In Vitro and Dentin Regeneration In Vivo

The purpose of the present study was to investigate the effect of a peptide (i.e., SESDNNSSSRGDASYNSDES) derived from dentin phosphophoryn (DPP) with arginine-glycine-aspartic acid (RGD) motifs on odontoblast differentiation in vitro and to compare it with calcium hydroxide—a material used conventionally for vital pulp therapy—in terms of reparative dentin formation and pulp inflammation in vivo. Alkaline phosphatase activity assay and alizarin red S staining were performed to evaluate odontoblast-differentiation in cell culturing experiments. To observe the reparative dentin formation and pulp inflammation animal experiment was performed and examined by histological methods. The difference between the experimental group and the control group was analyzed statistically using a one-way ANOVA test. The results revealed that the DPP-derived RGD-containing peptide triggered odontoblast differentiation and mineralization in vitro. In rats undergoing direct pulp capping, the DPP-derived RGD-containing peptide was found to induce intensively formed reparative dentin with high compactness at week 4. On histological and morphometrical examinations, a smaller degree of pulpitis was observed in the specimens treated with the peptide than in those treated with calcium hydroxide. This study suggests that the DPP-derived RGD-containing peptide is a biocompatible, biodegradable and bioactive material for dentin regeneration.     

Structural Response of Steel Jacket-UHPC Retrofitted Reinforced Concrete Columns under Blast Loading

The lateral capacity of exterior concrete columns subjected to a blast load is the key factor in the building collapse probability. Due to potentially severe consequences of the collapse, efforts have been made to improve the blast resistance of existing structures. One of the successful approaches is the use of ultra-high-performance-concrete (UHPC) jacketing for retrofitting a building’s columns. The columns on the first floor of a building normally have higher slenderness due to the higher first story. Since an explosion is more likely to take place at the ground level, retrofitting the columns of the lower floors is crucial to improve a building’s blast resistance. Casting a UHPC tube around a circular RC column can increase the moment of inertia of the column and improve the flexural strength. In this study, a retrofitting system consisting of a UHPC layer enclosed by a thin steel jacket is proposed to improve the blast resistance of buildings in service. Most of the previous research is focused on design aspects of blast-resistant columns and retrofitting systems are mostly based on fiber reinforced polymers or steel jackets. A validated FE model is used to investigate the effectiveness of this method. The results showed significant improvement both at the component and building system levels against combined gravity and blast loading.     

The hepatoduodenal ligament revisited: cross-sectional imaging spectrum of non-neoplastic conditions

Introduction

The hepatoduodenal ligament is frequently involved by conditions affecting the portal triad and surrounding structures, including a vast array of non-neoplastic conditions. Due its unique location between the retroperitoneum and the peritoneal space, the hepatoduodenal ligament is also targeted by inflammatory conditions involving the retroperitoneum and the liver. Finally, the presence of lymphatics and of the biliary tracts makes the hepatoduodenal ligament a route of spread for a variety of infections. The purpose of this pictorial essay is twofold: to review the cross-sectional radiological anatomy and variants of the structures within the hepatoduodenal ligament, and to illustrate the non-neoplastic conditions that may arise within the hepatoduodenal ligament.

Conclusion

Familiarity with these specific entities and their cross-sectional imaging findings is fundamental for a more accurate diagnosis.

     

Ruptured inferior vena cava aneurysm in the setting of mural vascular malformation: A case report

Aneurysm of the inferior vena cava is a rare anomaly with a very few reported cases worldwide. We report the case of a 26-years-old man with acute severe abdominal pain and hypovolemic shock following an episode of syncope. Ultrasonography showed a fusiform aneurysmal dilation of the infra-hepatic inferior vena cava (IVC), with a large saccular portion at its posterolateral wall and mural thrombosis. Abdominal computed tomography scan revealed extension to the right renal vein and adhesion to the right kidney. The saccular aneurysm and the right kidney were resected, and anatomopathological examination revealed a cavernous hemangioma. All symptoms disappeared after surgery. This is the first reported case of symptomatic congenital saccular aneurysm of the IVC due to mural vascular malformation and with involvement of the right kidney leading to nephrectomy.     

Role of concealed conduction and allied phenomena in the genesis,maintenance, and termination of cardiac arrhythmias

Concealed conduction is a common electrocardiographic phenomenon whereby a series of events may occur as a result of incomplete propagation of an impulse. The occurrence, maintenance, and resolution (termination) of several events such as functional block and cardiac arrhythmias are linked to concealed conduction. This phenomenon should be suspected on the surface electrocardiogram whenever an arrhythmic event occurs unexpectedly. Several electrophysiological concepts such as transseptal conduction and linking phenomenon are close allies of concealed conduction. His‐bundle electrocardiography and comprehensive electrophysiology may be needed to verify this phenomenon.
