The measurement of charge for induction-based fluidic MALDI dispense event and nanoliter volume verification in real time.

This study preliminarily investigates whether nanoliter volumes of concentrated polar liquids and organic monomers launched to targets using induction based fluidics (IBF) can be verified through the real time charge measurements. We show that using a nanoliter IBF dispensing device and nanocoulomb meter, charge measurements made on nanoliter drops in real time are correlated with surface area following Gauss's Law. We infer the "induction only" formation of the double layer showing the ability to determine nanoliter volumes, nearly instantaneously, in real time.

Dacryocystitis presenting as post-septal cellulitis: a case report.

Dacryocystitis is relatively common, the majority of patients present with pre-septal cellulitis and not an orbital abscess due to anatomical barriers. The authors report a case of dacryocystitis presenting as post-septal cellulitis in a postmenopausal lady with an underlying malignancy. Following antibiotic therapy and elective dacryocystorhinostomy the patient is still under follow-up, and has no further recurrence of symptoms.

Evaluation of a point-of-care blood analyzer and determination of reference ranges for blood parameters in rockfish.

Objective: To compare values of blood parameters in rockfish obtained by use of a point-of-care portable blood analyzer with values determined by a veterinary diagnostic laboratory, calculate reference ranges for various blood parameters in black rockfish, and compare values of blood parameters in clinically normal fish with those of fish with clinical abnormalities.

Design: Prospective study.

Animals: 41 captive adult black rockfish (Sebastes melanops) and 4 captive adult blue rockfish (Sebastes mystinus).

Research as a catalyst for change: the transition from student to Registered Nurse.

This paper outlines the qualitative findings of a study exploring the transition from student to Registered Nurse and the catalytic effect of the way in which newly registered nurses are prepared for this role change. The study explored the experiences of one cohort of students undertaking the pre-registration Advanced Diploma in Nursing Studies at the University of Sheffield. Data were collected pre-qualification and post-qualification in order to compare the expectations and reality of the transition period.
