Article Abstract

Background: A system of network forms of Kedem-Katchalsky (K-K) equations for ternary non-electrolyte solutions is made of eight matrix equations containing Peusner's coefficients R(ij), L(ij), H(ij), W(ij), K(ij), N(ij), S(ij) or P(ij) (i, j ∈ {1, 2, 3}). The equations are the result of symmetric or hybrid transformation of the classic form of K-K equations by the use of methods of Peusner's network thermodynamics (PNT).

Objectives: Calculating concentration dependences of the determinant of Peusner's coefficients matrixes R(ij), L(ij), H(ij), W(ij), S(ij), N(ij), K(ij) and P(ij) (i, j ∈ {1, 2, 3}).

Material And Methods: The material used in the experiment was a hemodialysis Nephrophan membrane with specified transport properties (L(p), σ, Ω) in aqueous glucose and ethanol solution. The method involved equations for determinants of the matrixes coefficients R(ij), L(ij), H(ij), W(ij), S(ij), N(ij), K(ij) or P(ij) (i, j ∈ {1, 2, 3}).

Results: The objective of calculations were dependences of determinants of Peusner's coeffcients matrixes R(ij), L(ij), H(ij), W(ij), S(ij), N(ij), K(ij) or P(ij) (i, j ∈ {1, 2, 3}) within the conditions of solution homogeneity upon an average concentration of one component of solution in the membrane (C1) with a determined value of the second component (C2).

Conclusions: The method of calculating the determinants of Peusner's coeffcients matrixes R(ij), L(ij), H(ij), W(ij), S(ij), N(ij), K(ij) or P(ij) (i, j ∈ {1, 2, 3}) is a new tool that may be applicable in studies on membrane transport. Calculations showed that the coefficients are sensitive to concentration and composition of solutions separated by a polymeric membrane.

Department of Minimally Invasive & Interventional Radiology, Sun Yat-Sen University Cancer Center and Sun Yat-Sen University State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, 651 Dongfeng East Road, Guangdong, 510060, Guangdong Province, China.

Purpose: To compare the safety and efficacy of left versus right internal jugular vein access for portal vein puncture during transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with a small liver and short vertical puncture distance.

Materials And Methods: The vertical distance from the hepatic vein orifice to the puncture point of the portal vein was measured by CT and DSA. A distance ≤ 30 mm is defined as a short vertical puncture distance.

Background: Left innominate vein occlusion is a known complication of pacemaker and central venous catheter placement. For dialysis-dependent patients with an arteriovenous fistula (AVF), this can prevent successful hemodialysis and may require surgical intervention.

Case Report: An 8-month-old male was diagnosed with hemolytic uremic syndrome and became dialysis-dependent at 11 months of age.

Background: The network forms of Kedem-Katchalsky (K-K) equations for ternary non-electrolyte solutions may contain one of the eight Peusner's coefficients: R(ij), L(ij), H(ij), W(ij), N(ij), K(ij), S(ij) or P(ij) (i, J ∈ {1, 2, 3}). These coefficients form the third degree matrixes ofPeusner's coefficients [R], [L], [H], [W], [N], [K], [S] or [P].

Objectives: Calculation of dependencies of the Peusner's coefficients W(ij) (i, j ∈ {1, 2, 3}) and det [W], on the average concentration of one component in the membrane solution (C1) for several different values of the second component set (C2).
