background polyvinyl alcohol (pva) is one of the well-known polymers, which has been used in numerous biomedical applications because of its good biocompatibility. objectives due to problems made by the therapeutics already used for leishmaniasis, the aim of this study was to evaluate the effect of pva containing artemether in treating cutaneous leishmaniasis in balb/c mice. materials and metho...

Introduction There are several materials currently used as tissue mimicking phantoms depending on the imaging modality in question. Poly(vinyl alcohol) cryogel (PVA-C) not only has the potential to be used as a multi-modality phantom, but it also has a variety of biomedical advantages, including its nontoxic, non-carcinogenic and biodegradable characteristics (1). This polymer is easily produce...

A Love wave humidity sensor is developed by using a multilayer structure consisting of PVA/SiO2 layers on an ST-90°X quartz substrate. The theoretical result shows that the sensor with such a two-layer structure can achieve a higher sensitivity and a smaller loss than the structures with a single polymer layer. Comparative experiments are performed for the sensor incorporating PVA/SiO2 layers a...

Background. We hypothesized that the effect of pimobendan (UD-CG 115 BS) to increase calcium sensitivity of contractile protein might result in less myocardial oxygen consumption (Vo2) in comparison with dobutamine when they enhance ventricular contractility to the same extent. To examine this hypothesis, we compared the effects of pimobendan and dobutamine on left ventricular contractility and...

1. Polyvinyl Alcohol Phantoms (Polyvinyl alcohol gels) Polyvinyl alcohol cryogel (PVA-C) is a typical tissue-mimicking material for ultrasound imaging. It is formed from PVA solution undergoing some freezethaw (F/T) cycles. As the optical and mechanical properties change with the number of F/T cycle, certain requirements, like the scattering coefficient and absorption coefficient, for the phant...

In the current study, we sought to establish a novel rat model of portal vein arterialization (PVA) and evaluate its impact on liver regeneration after extended partial hepatectomy (PH). A total of 105 Sprague-Dawley rats were randomly assigned to three groups: 68% hepatectomy (the PH group), portal arterialization after 68% hepatectomy (the PVA group), and right nephrectomy only (the control g...

Microvascular surgery is becoming a prevalent surgical practice. Replantation, hand reconstruction, orthopedic, and free tissue transfer procedures all rely on microvascular surgery for the repair of venous and arterial defects at the millimeter and submillimeter levels. Often, a vascular graft is required for the procedure as a means to bridge the gap between native arteries. While autologous ...

Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging. The encapsul...

Correspondence To the Editor: Intraatrial reentry tachycardia (IART) has been reported to occur in 2% to 10% of Mustard and Senning patients at 10 years' follow‑up. We reported a case in which the cavo‑tricuspid isthmus (CTI) in both the systemic venous atrium (SVA) and pulmonary venous atrium (PVA) was necessarily targeted in a patient following Senning operation. The patient was a 26‑year‑old...

We studied the effects of ventricular end-systolic elastance (Ees) and effective arterial elastance (Ea) on the efficiency of energy transfer from pressure-volume area (PVA) to external mechanical work (EW) in the left ventricle of anesthetized closed-chest dogs. PVA represents the total mechanical energy generated by ventricular contraction, which is an intermediate form of energy between oxyg...
