The Micrometer Syringe

A jig for the agla micrometer syringe for automatic quantitative applications in paper electrophoresis.

This test is quick, cheap, simple, and painless. It is adequate in most cases for the diagnosis of achlorhydria. The usefulness of test meals for diagnosing any other gastric abnormality is questionable. The term " achlorhydria " is usually taken to mean that the gastric juice has a pH of more than 3, as shown by Topfer's reagent or thymol blue. It denotes a relative " an "-acidity rather than ...

The Sterility of the Syringe

The syringe gap: an assessment of sterile syringe need and acquisition among syringe exchange program participants in New York City

BACKGROUND Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction, while separate survey data from individuals using these programs indicate that frequent injecting - at least daily - is common. Together, these data suggest a possible "syringe gap" between the number of injections performed b...

Downward movement of syringe pumps reduces syringe output.

We studied how lowering a syringe pump and changing the outflow pressure could affect syringe pump output. We experimentally reduced the height of three different syringe pump systems by 80 cm (adult setting) or 130 cm (neonatal setting), as can happen clinically, using five flow rates. We measured the time of backward flow, no flow and the total time without flow. An exponential negative corre...

Syringe-injectable electronics.

Seamless and minimally invasive three-dimensional interpenetration of electronics within artificial or natural structures could allow for continuous monitoring and manipulation of their properties. Flexible electronics provide a means for conforming electronics to non-planar surfaces, yet targeted delivery of flexible electronics to internal regions remains difficult. Here, we overcome this cha...
