Mixed-mode liquid chromatography coupled to tandem mass spectrometry for the analysis of aminoglycosides in meat.

Anal. Bioanal. Chem 406(20) , 4941-53, (2014)

A novel LC-MS/MS method has been developed for the determination of 13 aminoglycoside antibiotics in meat products. Among the chromatographic columns tested, the mixed-mode Obelisc R provided the best performance. Electrospray has been used for the coupling o...

Use of experimental design to optimize a triple-potential waveform to develop a method for the determination of streptomycin and dihydrostreptomycin in pharmaceutical veterinary dosage forms by HPLC-PAD.

J. Pharm. Biomed. Anal. 104 , 81-9, (2014)

An HPLC-PAD method using a gold working electrode and a triple-potential waveform was developed for the simultaneous determination of streptomycin and dihydrostreptomycin in veterinary drugs. Glucose was used as the internal standard, and the triple-potential...

Aminoglycoside analysis in food of animal origin with a zwitterionic stationary phase and liquid chromatography-tandem mass spectrometry.

Anal. Chim. Acta 882 , 127-39, (2015)

In this study, fourteen highly polar aminoglycoside (AGs) antibiotics were selected. Various stationary phases were tested, including Obelisc R, ZIC-HILIC, BEH amide and aminopropyl. The nature of the stationary phase, mobile phase (water or buffer solutions ...

A polyvinyl alcohol-functionalized sorbent for extraction and determination of aminoglycoside antibiotics in honey.

J. Chromatogr. A. 1403 , 32-6, (2015)

A novel highly hydrophilic sorbent simply prepared by coating polyvinyl alcohol (PVA) onto silica gel was used for extraction and determination of aminoglycoside antibiotics (AAs). The fabricated PVA coating is aimed to effectively protect core silica gel ins...

Transduction without tip links in cochlear hair cells is mediated by ion channels with permeation properties distinct from those of the mechano-electrical transducer channel.

J. Neurosci. 34(16) , 5505-14, (2014)

Tip links between adjacent stereocilia are believed to gate mechano-electrical transducer (MET) channels and mediate the electrical responses of sensory hair cells. We found that mouse auditory hair cells that lack tip links due to genetic mutations or exposu...

Events occurring during the previous lactation, the dry period, and peripartum as risk factors for early lactation mastitis in cows receiving 2 different intramammary dry cow therapies

J. Dairy Sci. 95(12) , 7015-26, (2012)

The objective of this study was to investigate the association between mastitis events occurring during the previous lactation, the dry period, and the peripartum period on the incidence of early lactation mastitis in cows receiving ceftiofur hydrochloride or...

Facilitated column selection in pharmaceutical analyses using a simple column classification system.

J. Chromatogr. A. 1101(1-2) , 103-14, (2006)

In this paper, the performance of a previously developed classification system applied to pharmaceutical chromatographic analyses, is investigated. The separation of seven different drug substances from their respective impurities was studied. The chromatogra...

The resting transducer current drives spontaneous activity in prehearing mammalian cochlear inner hair cells.

J. Neurosci. 32(31) , 10479-83, (2012)

Spontaneous Ca(2+)-dependent electrical activity in the immature mammalian cochlea is thought to instruct the formation of the tonotopic map during the differentiation of sensory hair cells and the auditory pathway. This activity occurs in inner hair cells (I...

Characteristics of urethral and epididymal semen collected from domestic cats--A retrospective study of 214 cases.

Theriogenology 84 , 1565-71, (2015)

This study was designed to describe and compare basic semen characteristics and sperm motility parameters obtained via computer-assisted sperm analysis (CASA) in feline semen collected from the urethra and epididymis, on the basis of large, unselected populat...

Streptococcus dysgalactiae isolates at calving and lactation performance within the same lactation.

J. Dairy Sci. 90(2) , 766-78, (2007)

The objective of the study was to investigate the association between early lactation Streptococcus dysgalactiae isolates and milk yield, somatic cell count (SCC), clinical mastitis, and culling in the same lactation. The 178 commercial dairy herds were rando...
