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 ...
شیر ترکیب پیچیدهای از مواد معدنی و زیستی مهمی است که برای رشد و تکامل نوزاد پستانداران لازم و ضروری است و ممکن است توسط فلزات سنگین نظیر سرب و کادمیوم آلوده شود. در این بررسی میزان غلظت سرب و کادمیوم در 12 نمونه ماست و 12 نمونه پنیر فراپالایش (UF) تولید شده در کارخانههای پگاه اصفهان و گلپایگان اندازهگیری شد. برای تعیین غلظت فلزات مزبور از روش طیفسنجی جذب اتمی با کوره و مطابق روش AOAC عمل گر...
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...
BACKGROUND The System 100 UF device allows ultrafiltration (UF) via peripheral access and is approved for use in heart failure (HF), although clinical trials defining optimal target population and clinical utility are lacking. We report our initial experience with clinical use of this system in very advanced, diuretic resistant HF patients. METHODS AND RESULTS Eleven HF patients (mean age 70 ...
Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Recent studies suggest that sulfated hetero-polysaccharides (UF) protect against developing PD. However, the detailed mechanisms of how UF suppress neuronal death have not been fully elucidated. We investigated the cytoprotective mechanisms of UF using human dopaminergic neuroblastoma SH-SY5Y cells as a PD model. UF ...
