Vaginal birth after cesarean delivery in twin gestations: A large, nationwide sample of deliveries

American Journal of Obstetrics and Gynecology, 2006
The purpose of this study was to assess the maternal morbidity associated with attempted vaginal birth after cesarean (VBAC) in twin gestations using a large, nationwide sample of deliveries.Data for this study were obtained from an administrative dataset, the Nationwide Inpatient Sample, a representative sample of discharges from non-Federal hospitals,

Implantable device for drug delivery and blood sampling in the rat

Journal of Applied Physiology, 1985
An implantable drug-delivery and venous sampling device is described that is constructed from a polyvinyl chloride catheter and a rubber intravenous catheter plug coated with Silastic. The implant was used for repeated venous sampling and for both administration of parenteral solutions and injections into the right colon of the rat for periods to 1 mo.

Fetal blood sampling in labour and the decision to delivery interval

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2008
To determine the time interval from decision to result for fetal blood sampling (FBS) and the time from an abnormal pH result to delivery of the neonate.A prospective study of 107 consecutive attempts at FBS on 72 out of 1450 patients in labour from 1st April 2006 to 1st August 2006 at St James University Hospital in Leeds, England.

The Epidemiology of Postpartum Hemorrhage in a Large, Nationwide Sample of Deliveries

Obstetric Anesthesia Digest, 2010
In this study, we sought to (1) define trends in the incidence of postpartum hemorrhage (PPH), and (2) elucidate the contemporary epidemiology of PPH focusing on risk factors and maternal outcomes related to this delivery complication.Hospital admissions for delivery were extracted from the Nationwide Inpatient Sample, the largest discharge dataset in ...

Sample Delivery Techniques for Serial Crystallography

2018
In serial femtosecond crystallography (SFX), protein microcrystals and nanocrystals are introduced into the focus of an X-ray free electron laser (FEL) beam ideally one-by-one in a serial fashion. The high photon density in each pulse is the double-edged sword that necessitates the serial nature of the experiments.

Microfluidic sample delivery for serial crystallography using XFELs

Analytical and Bioanalytical Chemistry, 2019
Serial femtosecond crystallography (SFX) with X-ray free electron lasers (XFELs) is an emerging field for structural biology. One of its major impacts lies in the ability to reveal the structure of complex proteins previously inaccessible with synchrotron-based crystallography techniques and allowing time-resolved studies from femtoseconds to seconds ...

Micromachined needles for microbiological sample and drug delivery system

Proceedings International Conference on MEMS, NANO and Smart Systems, 2004
In this paper, the research and development of micromachined needles for microbiological sample and drug delivery system are reviewed. The micromachined needles can be classified into in-plane and out-of-plane needles. The features of those microneedles are analyzed and discussed.

Sample delivery for structural biology at the European XFEL

Serial femtosecond crystallography (SFX) at X-ray free electron lasers (XFELs) is a valuable technique for time-resolved structural studies on enzymes. This method allows for the collection of high-resolution datasets of protein structures at various time points during a reaction initiated by light or mixing.

Sample Preparation and Delivery

As a direct-analysis technique, SIFT-MS has differing sample preparation and sample delivery requirements to GC, the most widely used technique for analysing volatile compounds. This chapter summarises the general principles of effective sample delivery to SIFT-MS instruments, with reference to the GC methods.
