Bu çalışmada, kolesterol amperometrik tayini için Prusya mavisi (PB) temelli biyosensörler hazırlandı. amaçla, jelatin ve gluteraldehit içeren ortam kullanılarak çapraz bağlama tekniği ile PB oksidaz (COx) enzimi screen-printed elektrotların (SPE) yüzeyine immobilize edildi. SPE/PB/COx uygun oldukları gözlendi optimizasyon çalışmaları bu enzim elektrotları yapıldı. elektrodu optimum miktarı, or...

objective: saffron petal is a by-product that contains flavonoids and anthocyanins. in order to study the effects of saffron petal extract (spe) on blood parameters, immune system, and spleen histology, five treatments (n=6) were used in a completely randomized design. materials and methods: the treatments were 0, 75, 150, 225, and 450 mg/kg body weight of spe. the spe was injected intraperiton...

In vitro bioassays are increasingly used for water quality monitoring. Surface water samples often need to be enriched to observe an effect and solid-phase extraction (SPE) is commonly applied for this purpose. The applied methods are typically optimised for the recovery of target chemicals and not for effect recovery for bioassays. A review of the few studies that have evaluated SPE recovery f...

BACKGROUND Serum free light chain (SFLC) measurements have recently come into use as an aid for diagnosing monoclonal gammopathy. We evaluated SFLC measurements in combination with serum protein electrophoresis (SPE) and clinical information for diagnosing multiple myeloma (MM) in a hospital population. METHODS We measured SFLCs in 3818 sera received for SPE over a 1-year period when patient ...

OBJECTIVES To determine the most clinically effective diagnostic testing strategy for plasma cell disorders in the clinical laboratory. METHODS Serum and urine samples from 2,799 patients with suspected plasma cell dyscrasias were tested by alternative diagnostic testing strategies consisting of serum protein electrophoresis (SPE) with either urine protein electrophoresis (UPE) or serum free ...

This paper describes the development of screen-printed (SPE) and carbon paste (CPE) sensors for the rapid and sensitive quantification of naphazoline hydrochloride (NPZ) in pharmaceutical formulations. This work compares the electroactivity of conventional carbon paste and screen-printed carbon paste electrodes towards potentiometric titration of NPZ. The repeatability and accuracy of measureme...

A faster and more efficient way of isolating and subsequently cleaning up the sterol fraction obtained from seed oils was developed based on an existing established method that used thin-layer chromatography (TLC) to isolate the sterol fraction (3). The newly developed method used solidphase extraction (SPE) to separate the sterol fraction from other compounds found in the unsaponifiable portio...

a solid-phase extraction (spe) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (rp-hplc) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (pahs) in the caspian seawater. a good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. the effect ...

PURPOSE Many researchers are trying to solve the metabolic syndrome by utilizing a variety of nutritional control and exercise. Of those, silkworm pupae peptides are known to inhibit the synthesis of fat. Therefore, we examine the effect of fat metabolism by supplying silkworm pupae (SP) for 5-week in swim-trained rats. METHODS Animals were divided into four groups as a group (n = 32) fed a n...

This work presents a comparative study of the analytical characteristics of two methods for the analysis of carbonyl compounds in wine, both based on the derivatization with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA). In the first method derivatives are formed in the solid phase extraction (SPE) cartridge in which the analytes have been previously isolated, while in the ...
