Abstract Background Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) use for circulatory support in shock is limited by increased left ventricular afterload. Impella and intra-aortic balloon pump (IABP) can be used conjunction with VA-ECMO to help unload the ventricle. Data comparing two strategies are limited. Purpose We performed a systematic review meta-analysis of published data ...

In the tunnel limit, the current-phase relation of Josephson junctions can be expanded as I(φ) = I1 sinφ + I2 sin 2φ. Standard BCS theory predicts that I1RN ∼ ∆/e and I2/I1 ∼ D, where RN is the resistance of the junction in the normal state, ∆ is the superconducting gap, and D ≪ 1 is the junction transparency. In the cuprates, the experimental value of I1RN (I2/I1) is much smaller (larger) than...

Abstract Introduction Patent foramen ovale (PFO) closure has emerged as a secondary prevention option in patients with PFO and cerebrovascular events. Despite its seemingly established efficacy, associated long-term outcomes – including safety remain unclear. Purpose To ascertain the extent to which percutaneous is able improve clinical cryptogenic vascular Methods We systematically searched ME...

Abstract Background Recently published randomized controlled trials (RCT) have questioned the utility of Fraction Flow Reserve (FFR) to guide revascularization in patients with multivessel coronary artery disease (CAD) as compared Angiography Purpose This current analysis aimed compare clinical outcomes associated FFR guided versus standard angiography-guided for CAD using a large number stable...

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and declared as a global pandemic in March 2020. There special immune tolerance pregnant woman, predisposes to viral infection, then increased risk complication. Meta analysis was performed using preferred reporting items for systematic reviews meta-analyses (PRISMA) guidlines with comp...

Elemental gold powder is easily oxidised under mild reaction conditions with 1 : 1 I(2)-adducts of the thioamides 3-methyl-benzothiazole-2-thione (mbtt) and 1-methyl-1H-benzimidazole-2(3H)-thione (mbit) with separation of the ionic complexes [Au(I)(mbtt)(2)]I(3) (1) and [(mtbiH)(2)](AuI(4))I(3) (2) [mtbiH = the imido protonated form of 2-(methylthio)benzimidazole] (gold oxidation yield >78% and...

The vibrational frequency of the I2 2 chromophore in size-selected I2 ~Ar!n and I2 ~CO2!n clusters has been measured to wave-number accuracy. The frequencies are determined by creating a coherent superposition of vibrational levels with a femtosecond laser pulse via a resonance impulsive stimulated Raman scattering process. The resulting wave-packet oscillations are detected with femtosecond ph...

Purpose To compare the effects of dexmedetomidine (Dex) and fentanyl as adjuvants to local anesthetics in spinal anesthesia. Methods Two researchers independently searched the PUBMED, EMBASE, Cochrane library, and CBM for randomized controlled trials comparing the effects of Dex and fentanyl as adjuvants to local anesthetics for intrathecal injection. Results A total of 639 patients from ni...

Objectives. To establish a new method for determination of antioxidant capacity of human urine based on the redox couple I2/KI and to evaluate the redox status of healthy and diseased individuals. Methods. The method was based on the linear relationship between oxidation reduction potential (ORP) and logarithm of concentration ratio of I2/KI. ORP of a solution with a known concentration ratio o...
