Recent studies suggest that the hydroxyl radical (-OH) plays a pathogenetic role in postischemic ventricular dysfunction (myocardial "stunning"). This concept, however, is predicated exclusively on results obtained in anesthetized open-chest preparations, which are subject to the confounding influence of many unphysiological conditions and in which both myocardial stunning and free radical gene...

Introduction Diffusion weighted imaging(DWI) is a powerful tool to qualitatively and quantitatively evaluate pancreatic cancer. With the increasingly clinical application of 3.0T MR, techniques of DWI on pancreas were needed to be further clarified and understood, because of its greater energy deposition, magnetic susceptibility artifacts, more sensitivity of respiration, movement of blood vess...

OBJECTIVES The authors sought to investigate the accuracy of transthoracic echocardiography (TTE)-derived parameters in the identification of bileaflet aortic prosthesis dysfunction, compared with fluoroscopy (FL). BACKGROUND Identification of bileaflet aortic prosthesis dysfunction is challenging, because high mean pressure gradient (MPG >20 mm Hg) is not proof of prosthetic obstruction (AVP...

INTRODUCTION Adipose tissue-derived stem cells (ADSCs) herald tremendous promise for clinical application in a wide range of injuries and diseases. Several preclinical reports demonstrate their efficacy in the treatment of cavernous nerve (CN) injury-induced erectile dysfunction in rats. It was recently illustrated that these effects were established as a result of ADSC migration to the major p...

The oxygen free radical system has been reported to be activated by influenza virus infection in the lungs. However, the involvement of oxygen radicals in viral myocarditis is still unknown. Captopril, an angiotensin-converting enzyme (ACE) inhibitor and potent free radical scavenger with a sulfhydryl group, was effective for the treatment of viral myocarditis, while enalapril, an ACE inhibitor...

BACKGROUND Infections with high-risk human papillomaviruses (Hr-HPV) can cause malignant transformation of the human cervical epithelium. HPV DNA tests generally are very sensitive to detect cervical neoplastic lesions but also identify transient HPV infections. As a consequence, the specificity and positive predictive value are low. METHODS We analyzed viral load of Hr- and possibly Hr-HPV t...

Umami is considered to be the fifth basic taste quality and is elicited by glutamate. The mouse is an ideal rodent model for the study of this taste quality because of evidence that suggests that this species, like humans, may sense umami-tasting compounds as unique from other basic taste qualities. We performed single-unit recording of taste responses in the parabrachial nucleus (PbN) of anest...

Statistical image reconstruction (SIR) methods for X-ray CT improve the ability to produce high-quality and accurate images, while greatly reducing patient exposure to radiation. The challenge with further dose reduction to an ultralow level by lowering the X-ray tube current is photon starvation and electronic noise starts to dominate. This introduces negative or zero values into the raw data ...

Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions integrated dual photocatalytic system. This overcomes the need of expensive photosensitizers, organic ligands additives well limitations catalyst deactivation in existing photo/Ni catalytic cross-coupling reactions. The Ni-mpg-CNx dem...

Abstract This paper presents the experimental results of heat transfer coefficient ice slurry in distribution phase order to conserve fish and shellfish where ideal temperature oscillates between 0 °C 2 °C. The required energy power absorbed during exchange air is assimilated transport capacity (in kW cooling at full melt off). secondary fluid was prepared by mixing monopropylene glycol, MPG, w...
