INTRODUCTION Computer-aided medical technologies are currently restricted by the limited understanding of the mechanical response of solid abdominal organs to finite loading conditions typical of surgical manipulation [5]. This limitation is a result of the difficulty in acquiring the necessary data on whole organs. To develop a constitutive model capable of predicting complex surgical scenario...

Equilibrium or meta-equilibrium incomplete thermostatistics with different q indices Abstract We discuss a possibility of establishing a nonextensive incomplete statistics based on Tsallis entropy for equilibrium systems with different q values.

PURPOSE To demonstrate and quantify the heat sink effect in hepatic microwave ablation (MWA) in a standardized ex vivo model, and to analyze the influence of vessel distance and blood flow on lesion volume and shape. MATERIALS AND METHODS 108 ex vivo MWA procedures were performed in freshly harvested pig livers. Antennas were inserted parallel to non-perfused and perfused (700,1400 ml/min) gl...

Reflex vasoconstriction is attenuated in aged skin due to a functional loss of adrenergic vasoconstriction. Bioavailability of tetrahydrobiopterin (BH4), an essential cofactor for catecholamine synthesis, is reduced with aging. Locally administered BH4 increases vasoconstriction through adrenergic mechanisms in aged human skin. We hypothesized that oral sapropterin (Kuvan, a pharmaceutical BH4)...

In this paper, dynamic modeling of a double layer cylindrical functionally graded (FG) microshell is considered. Modeling is based on the first-order shear deformation theory (FSDT), and the equations of motion are derived using the Hamilton's principle. It assumes that functionally graded length scale parameter changes along the thickness. Generalized differential quadrature method (GDQM) is u...

drawing on henri meschonnic’s notion of an “inscient ethics,” and putting “inscience” into dialogue with the old ideal of a “science” of translation, the article explores the collective socio-affective ecologies that organize and regulate social and professional norms and values of translation below the level of conscious awareness—as the true underlying structure not only of “subjectivity” (so...

carnitine is a vital biologic substance for transporting fatty acids into myocytes. it also facilitates fatty acids β-oxidation for energy production. in this study, effects of l-carnitine (l-car) on apoptosis in the ischemic isolated rat heart were investigated. male sprague-dawley rats were divided into four groups and anesthetized by sodium pentobarbital. the heart was removed and mounted on...

BACKGROUND It has previously been shown that the viability of swine uteri can be maintained within the physiological range in an open perfusion model for up to 8 hours. The aim of this study was to assess medium- to long-term perfusion of swine uteri using a modified Krebs-Ringer bicarbonate buffer solution (KRBB) in the established open perfusion model. METHODS In an experimental study at an...

T-2 toxin, a trichothecene mycotoxin, is considered to be one of the most toxic compounds that are produced by molds, particularly the Fusarium species. Fusarium species have been recognized as a great agricultural problem. They occur worldwide on a variety of plant hosts and cereal grains. The aim of this study was to investigate T-2 toxin-induced liver injury using in situ perfused rat liver....
