Differences in vascular reactivity between isolated ultrafiltration (i-UF) and hemodialysis (UF + HD) have been attributed to various factors, including differences in core temperature (CT) and energy transfer (ET). However, the relative importance of these thermal factors is not known. The aim of this study was to elucidate to what extent differences in ET are responsible for the divergent vas...

to investigate the igg content and its variations in uterine fluid (uf) during the estrous cycle of the cow and to compare them with those of the blood serum (s), six pairs of serum and uf samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from urmia abattoir. the uf samples were collected by gentle scraping of the endometrium using a ...

We assessed the Sysmex UF-50 for reproducibility of results and carryover rate by performing between- and within-run precision analyses on 315 urine samples, evaluated the feasibility of using the UF-50 to measure urinary cellular and noncellular components by comparing results from the UF-50 with results of manual urinalysis using the Kova system, and performed side-by-side comparison of the w...

A membrane filtration system was used to remove organic compounds, suspended solids, colour and turbidity from anaerobically treated dairy wastewater. Direct microfiltration (MF), ultrafiltration (UF), MF-UF and a combination of UF with coagulation using two conventional coagulants were investigated. The installation with ceramic membranes was operated at a pressure of 0.15 MPa (MF) and 0.3 MPa...

BACKGROUND Ultrafiltration (UF) is assumed to enhance urea removal during haemodialysis (HD) because of convective transport and because of contraction of urea distribution volume. However, UF-induced blood volume reduction has been hypothesized to enhance peripheral urea sequestration and post-dialysis urea rebound (PDUR), possibly reducing HD effectiveness. The effect of UF on PDUR was invest...

BACKGROUND AND OBJECTIVES In the Ultrafiltration versus Intravenous Diuretics for Patients Hospitalized for Acute Decompensated Heart Failure trial, ultrafiltration (UF) removed volume more effectively than usual care (UC). Hypothetically, UF may be superior to UC due to increased sodium (Na) removal and less neurohormonal activation. We compared UF and UC in a randomized pilot trial of target ...

To investigate the IgG content and its variations in uterine fluid (UF) during the estrous cycle of the cow and to compare them with those of the blood serum (S), six pairs of serum and UF samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from Urmia abattoir. The UF samples were collected by gentle scraping of the endometrium using a ...

A powdery product was obtained by the reaction of methylolated melamine with alkyl resorcinols to form melamine-bridged alkyl resorcinols (MARs). The effects of the addition of this powder on the bonding strength and formaldehyde emission of urea–formaldehyde (UF) resins were investigated. Three types of UF resins with a formaldehyde/urea molar ratio of 1.3 synthesized by condensation at pH 1.0...

A pink, high molecular weight form of uteroferrin (Uf) has been isolated from uterine secretions and allantoic fluid of pigs. This protein fraction (denoted FIII) which is relatively stable under physiological conditions of pH, ionic strength, and temperature has a molecular weight of about 80,000, a value approximately twice that of purple Uf (Mr approximately 35,000) isolated from a separate ...

BACKGROUND Hemodialysis (HD) with ultrafiltration (UF) in chronic renal replacement therapy is associated with hemodynamic instability, morbidity and mortality. Sublingual Sidestream Dark Field (SDF) imaging during HD revealed reductions in microcirculatory blood flow (MFI). This study aims to determine underlying mechanisms. METHODS The study was performed in the Medical Centre Leeuwarden an...
