Human prostate specific antigen (PSA) standard solution and prostate specific antibody (Ab1 and Ab2) were purchased from Shenggong Bioengineering Ltd Company (Shanghai, China). Glutaraldehyde (25% aqueous solution), bovine serum albumin (BSA), (3-aminopropyl) triethoxysilane (APTES), Tri(2,2′-bipyridyl) dichlororuthenium (II) hexahydrate, and chitosan (CS) were obtained from Sigma-Aldrich Chem....

We evaluated the efficiency of five membrane filters for recovery of Cryptosporidium parvum oocysts and Giardia lamblia cysts. These filters included the Pall Life Sciences Envirochek (EC) standard filtration and Envirochek high-volume (EC-HV) membrane filters, the Millipore flatbed membrane filter, the Sartorius flatbed membrane filter (SMF), and the Filta-Max (FM) depth filter. Distilled and ...

At present, the filter theory of $BL$textit{-}algebras has been widelystudied, and some important results have been published (see for examplecite{4}, cite{5}, cite{xi}, cite{6}, cite{7}). In other works such ascite{BP}, cite{vii}, cite{xiii}, cite{xvi} a study of a filter theory inthe more general setting of residuated lattices is done, generalizing thatfor $BL$textit{-}algebras. Note that fil...

Escherichia coli introduced into autoclaved filtered river water survived for up to 260 d at temperatures from 4 degrees to 25 degrees C with no loss of viability. Survival times were less in water which was only filtered through either a Whatman filter paper or a 0.45 micron Millipore filter or in untreated water, suggesting that competition with the natural microbial flora of the water was th...

INTRODUCTION accounted for by the uptake of Cal+ and accompanying anions (17) . The swelling of isolated mitochondria in response to the introduction of orthophosphate (Pi) to the suspending medium has been studied in a number of works (1-15) . In particular, Packer (11) found the P ; induced swelling to be dependent on the presence of state 4 and to be reversed upon the induction of state 3 . ...

OBJECTIVE To delineate the light and electron microscopic features of tissue removed at the time of macular hole surgery. METHODS The ocular fluid specimens were concentrated using Millipore filters and stained with a modified Papanicolaou and the periodic acid-Schiff stains in 697 cases. In 92 cases, surgically isolated tissue was processed and examined by electron microscopy. RESULTS The ...

The composition of the emulsified oil and of the micellar phases obtained when a glyceride-fatty acid mixture is dispersed in bile salt solution has been defined. The micellar phase in equilibrium with the emulsified oil phase was obtained by filtration through Millipore filters. The behavior of different lipids in such systems was defined as the partition ratio, micellar/emulsified oil phase (...

the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...
