Michio Mineshima
Many kinds of technologies have been introduced and successfully developed for therapeutic apheresis. During the DFPP treatments, the patient's blood volume (BV) often decreases with time due to albumin loss induced by inadequate albumin infusion in a supplementation fluid. We examined the change of BV by a continuous hematocrit (HCT) monitor, CRIT-LINE™, during an in vivo study for nine patients. As a result, albumin loss was fairly occurred in some DFPP treatments. The decrease of patient's BV was induced by an oncotic pressure drop due to albumin loss and often resulted in a blood pressure drop...

The controlled drug release from hydrogel-based drug delivery systems is a topic of large interest for research in pharmacology. The mathematical modeling of the behavior of these systems is a tool of emerging relevance, since the simulations can be of use in the design of novel systems, in particular for complex shaped tablets. In this work a model, previously developed, was applied to complex-shaped oral drug delivery systems based on hydrogels (Dome Matrix®). Furthermore, the model was successfully adopted in the description of drug release from partially accessible Dome Matrix® systems (systems with some surfaces coated)...

BACKGROUND AND OBJECTIVE: Cerebral ischemia affects hepatic enzymes and brain permeability extensively. Piracetam was investigated up to phase III of clinical trials and there is lack of data on brain penetration in cerebral ischemic condition. Thus, knowledge of the pharmacokinetics and brain penetration of piracetam during ischemic condition would aid to improve pharmacotherapeutics in ischemic stroke. METHODS: Focal cerebral ischemia was induced by middle cerebral artery occlusion for 2 h in male Wistar rats followed by reperfusion...

Precise control of the glutathione (GSH):glutathione disulfide (GSSG) balance is vital for the developing embryo, but it is not yet well understood how GSH levels and the GSH redox state are regulated, maintained, and modulated over the course of mammalian embryonic development. In this study, we characterize and connect thiol redox dynamics, protein synthesis, volumetric growth and net cysteine fluxes over the course of early organogenesis (gestational day (GD) 10 to GD11.13) in the rat embryo. Our results show that despite a significant exponential growth of conceptal volumes and protein mass, the GSH:GSSG redox balance is remarkably stable during early organogenesis, with distinct redox potentials for the visceral yolk sac (VYS) (-218mV) and the embryo proper (EMB) (-222mV)...

REVIEW
Tetsuya Ito, Norio Hanafusa
A standard strategy against ascites, a common symptom observed in cirrhotic and cancer patients, includes restriction of sodium intake and use of a diuretic. Paracentesis is a widely applied method against refractory ascites that do not react to such treatment. However, emerging fatigue and hemodynamic instability are possibly attributable to a loss of protein included in ascites. Cell-free and Concentrated Ascites Reinfusion Therapy (CART) is also applied against refractory ascites. CART comprises three processes...

The computation of diffusion coefficients in molecular systems ranks among the most useful applications of equilibrium molecular dynamics simulations. However, when dealing with the problem of fluid diffusion through vanishingly thin interfaces, classical techniques are not applicable. This is because the volume of space in which molecules diffuse is ill-defined. In such conditions, non-equilibrium techniques allow for the computation of transport coefficients per unit interface width, but their weak point lies in their inability to isolate the contribution of the different physical mechanisms prone to impact the flux of permeating molecules...

J Baz Jackson
We have recently criticised the natural pH gradient hypothesis which purports to explain how the difference in pH between fluid issuing from ancient alkali vents and the more acidic Hadean ocean could have driven molecular machines that catalyse reactions that are useful in prebiotic and autotrophic chemistry. In this article, we temporarily suspend our earlier criticism while we consider difficulties for primitive organisms to have managed their energy supply and to have left the vents and become free-living...

We hypothesized that constant compression of the knee would mobilize residual synovial fluid and promote successful arthrocentesis. Two hundred and ten knees with grade II-III osteoarthritis were included in this paired design study: (1) conventional arthrocentesis was performed with manual compression and success and volume (milliliters) determined; and (2) the intra-articular needle was left in place, and a circumferential elastomeric brace was tightened on the knee to provide constant compression. Arthrocentesis was attempted again and additional fluid volume was determined...

Cardiovascular disease is a major concern in patients with end-stage kidney disease (ESKD). Inflammation induced by retention of uremic toxins, of which a substantial fraction has a molecular weight in the middle molecular range, has been associated with increased cardiovascular risk. In an attempt to reduce inflammation and thus cardiovascular toxicity in patients with ESKD, hemodiafiltration (HDF) has been promoted to enhance the clearance of middle molecular weight substances during dialysis. However, HDF increases the technical complexity and costs, and requires ultrapure dialysis fluid...

High retention onset (HRO) is the designation for a new class of hemodialysis membranes. A unique characteristic of this class is the highly selective and controlled porosity resulting in sieving properties that provide a clinically desirable balance between middle/large molecular weight solute removal and albumin loss. Another defining feature of this membrane class is the relatively small fiber diameter, which produces high convective volumes in the form of internal filtration. The aim of the present study was to estimate, by semi-empirical methods, convective volumes for 2 new HRO dialyzers: Theranova 400 and Theranova 500 (Baxter International Inc...

Double filtration plasmapheresis (DFPP) was historically used for blood group incompatible renal transplantation. Very few studies are available worldwide regarding its efficiency in removing specific plasma components, and safety. We conducted a prospective observational cohort study over 1 year on patients undergoing DFPP for various renal indications. There were 15 patients with 39 sessions. The pre- and post-procedure plasma samples of serum IgG, IgA, IgM, fibrinogen, calcium, phosphate, potassium, and magnesium were analyzed...
