Identifying Priority Science Information Needs for Managing Public Lands.

Public lands worldwide provide diverse resources, uses, and values, ranging from wilderness to extractive uses. Decision-making on public lands is complex as a result and is required by law to be informed by science. However, public land managers may not always have the science they need.

Identifying Policy-relevant Indicators for Assessing Landscape Vegetation Patterns to Inform Planning and Management on Multiple-use Public Lands.

Understanding the structure and composition of landscapes can empower agencies to effectively manage public lands for multiple uses while sustaining land health. Many landscape metrics exist, but they are not often used in public land decision-making. Our objectives were to (1) develop and (2) apply a process for identifying a core set of indicators that public land managers can use to understand landscape-level resource patterns on and around public lands.

Analysis of biopharmaceutical formulations by Time Domain Nuclear Magnetic Resonance (TD-NMR) spectroscopy: A potential method for detection of counterfeit biologic pharmaceuticals.

H Time-Domain Nuclear Magnetic Resonance (TD-NMR) is used to characterize solutions of antibodies that simulate biologic pharmaceutical formulations. The results from these measurements are compared with those from solutions in which the concentration or identity of the antibody has been altered. TD-NMR is shown to be very sensitive to differences in the amount of antibody in solution, with the ability to detect variations in as low as 2 mg/mL.

Exploitation of the size-exclusion effect of reversed-phase high performance liquid chromatography for the direct analysis of diethylene triamine pentaacetic acid in therapeutic monoclonal antibody formulations.

Monoclonal antibodies (mAb) are being widely studied for the treatment of cancers and other diseases. The mAb is typically in a solution formulation and administered as an intravenous infusion. Ready-to-use solutions are favored for their clinical convenience but they can potentially suffer from a shorter shelf life due to accelerated rates of some forms of degradation such as oxidation, relative to lyophilized formulations.

Comprehensive determination of extractables from five different brands of stoppers used for injectable products.

Five commonly used stopper formulations were tested for extractables using three different vehicles (pH 3 citrate buffer with 20% w/v sulfobutylether-beta-cyclodextrin, pH 8 phosphate buffer and 50/50 v/v polyoxyethylated castor oil/dehydrated alcohol). The stoppers, made from butyl and halobutyl rubbers, coated and uncoated with proprietary films, were stored in contact with each vehicle for up to 6 months at 40 degrees C/75% relative humidity (RH) or for up to 24 months at 25 degrees C/60% RH. Samples were analyzed for the presence of extractables using inductively coupled plasma-atomic emission spectroscopy, ion chromatography, high-performance liquid chromatography, and gas chromatography.
