Twenty-six men on a liver transplant waiting list (12 had alcoholic cirrhosis, 8 suffered from posthepatitic cirrhosis, and 6 from cirrhosis of other etiologies) were eligible for this observation. Nineteen subjects underwent exercise testing to determine oxygen uptake at anaerobic threshold. In all patients dynamometry was performed to determine isokinetic muscle strength of knee extensor musc...

In tumor-bearing rats, most of the serum amino acids are used for synthesis and oxidation processes by the neoplastic tissue. In the present study, the effect of Walker 256 carcinoma growth on the intestinal absorption of leucine, methionine and glucose was investigated in newly weaned and mature rats. Food intake and carcass weight were decreased in newly weaned (NT) and mature (MT) rats beari...

We perform a Hamiltonian reduction of spherically symmetric Einstein gravity with a thin dust shell of positive rest mass. Three spatial topologies are considered: Euclidean (R3), Kruskal (S2 × R), and the spatial topology of a diametrically identified Kruskal (RP\{a point at infinity}). For the Kruskal and RP topologies the reduced phase space is four-dimensional, with one canonical pair assoc...

AIM The aim of the present study was twofold: 1. to compare the efficacy of three antipsychotics (ziprasidone, olanzapine and perazine) in schizophrenia 2. to compare the improvement in cognitive functioning between groups treated with the three different neuroleptics. METHOD A total of 58 Caucasian patients diagnosed with paranoid schizophrenia were recruited into the study group. We used th...

We analyse the Hawking-(Unruh) effect for a massive spinor field on the single exterior black hole spacetime known as the RP geon. This spacetime is an inextendible, space and time orientable black hole locally isometric to the Kruskal manifold but with only one exterior region. We find that the Hartle-Hawking-like vacuum |0G〉 contains exterior region Boulware modes in correlated pairs. Any ope...

The paper is devoted to a new approach for solution of some discrete extremal problems, such as the edge isoperimetric problem for graphs, the bisection width problem, the shadow and boundary minimization problems and others, on the carte-sian product of graphs and posets. The main aspect of the approach is in nding of some equivalence relations between the functions in the named problems via r...

A kinetic ballooning mode theory is developed from the gyrokinetic equation in the frequency range for which the ions are fluid, the thermal electron response is adiabatic and the hot electrons are non-interacting due to their large drift velocity. Trapped particle effects are ignored. The application of the quasineutrality condition together with the parallel and binormal components of Ampere’...

This study compared the use of lyophilized glutaraldehyde-preserved bovine pericardium (LGPBP), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), and Teflon felt (TF) as implants for vocal cords (VC) medialization and aimed to assess the endoscopic, macroscopic, and microscopic VC changes after medialization in a canine model. In 18 mongrel dogs, the right VC were medialized wit...

Brain metastasis from breast cancer is an increasingly important clinical problem. Here we assessed the role of CD44(hi)/CD24(lo) cells and pathways that regulate them, in an experimental model of brain metastasis. Notch signaling (mediated by γ-secretase) has been shown to contribute to maintenance of the cancer stem cell (CSC) phenotype. Cells sorted for a reduced stem-like phenotype had a re...
