In haemodialysis low-molecular-weight (LMW) heparin is increasingly used for anticoagulation. The advantages over unfractionated (UF) heparin are the lower bleeding risk and the lack of influence on lipid metabolism. However, no reliable and rapid method is available so far to control the efficacy and safety of LMW heparin during haemodialysis. The specific anti-factor Xa (aXa) chromogenic subs...

Uteroferrin (Uf) is a purple acid phosphatase with a bi-iron center. It is the major secretory product of the porcine uterus under the influence of progesterone and supplies iron to the developing fetuses during pregnancy. Tartrate-resistant acid phosphatases (TRAP) are clearly similar to Uf in many of their properties but are generally located intracellularly in lysosomes. To determine whether...

• UF coagulant dose controller was successfully developed and field tested. • Self-adaptive in-line UF coagulant dosing reduced coagulant consumption. • Real-time tracking of fouling resistance and backwash effectiveness. • Robust UF operation during conditions of deteriorating source water quality. ⁎ Corresponding authors.

In this work, H3PW12O40 (PPT) and nano-sized titania supported on urea formaldehyde (UF) resinwas prepared via an impregnation method. The prepared sample was characterized by X-raydiffraction (XRD), UV-Vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR),scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The photocatalyt...

The cause of the increase in core temperature (CT) during hemodialysis (HD) is still under debate. It has been suggested that peripheral vasoconstriction as a result of hypovolemia, leading to a reduced dissipation of heat from the skin, is the main cause of this increase in CT. If so, then it would be expected that extracorporeal heat flow (Jex) needed to maintain a stable CT (isothermic; T-co...

BACKGROUND The clinical criteria to assess hydration status are not always reliable. Hence, the development of techniques to estimate more accurately post-dialysis dry weight (DW) remains a major challenge. The present study evaluates the value of the inferior vena cava (IVC) diameter, plasma concentration of atrial natriuretic peptide (ANP), and plasma renin activity (PRA) in determining the D...

It is the purpose of this paper to construct unique factorization (uf) monoids and domains. The principal results are: (1) The free product of a well-ordered set of monoids is a uf-monoid iff every monoid in the set is a uf-monoid. (2) If M is an ordered monoid and F is a field, the ring ^[[iW"]] of all formal power series with well-ordered support is a uf-domain iff M is naturally ordered (i.e...

Excessive sodium gain is a major hindrance of sodium profiling hemodialysis (HD) that offsets the benefit in reducing intradialytic hypotension-related discomforts (IHD). Patients who showed frequent IHD (>30% of the sessions; n = 11) were enrolled in a prospective study that consisted of two phases. In the phase 1 study, eight treatment modalities were evaluated: Conventional HD (control), sod...

Uniform one-dimensional fragment UF=1 is a formalism obtained from first-order logic by limiting quantification to applications of blocks of existential (universal) quantifiers such that at most one variable remains free in the quantified formula. The fragment is closed under Boolean operations, but additional restrictions (called uniformity conditions) apply to combinations of atomic formulas ...
