A Micro Total Analysis System (μTAS) for the , Real-Time Tracking of Produced Water Discharges through Detection of PAHs and Other Aromatic Compounds.

Here, we present a novel micro Total Analysis System (μTAS) for the measurement of poly cyclic aromatic hydrocarbon (PAH) and other aromatic hydrocarbons (AHs) in water at ng/L levels and in real time (IMiRO). The μTAS is based on in-line membrane extraction followed by detection of extracted aromatic substances with fluorescence. An offshore field demonstration of the method was conducted close to produced water (PW) discharged in the North Sea.

Enzymatic assays for detecting lactose and sucrose in urine to reveal intravenous drug abuse with emphasis on buprenorphine.

Buprenorphine and methadone are commonly used medications for opioid maintenance treatment (OMT), using sublingual and oral administration, respectively. Although beneficial for OMT, these drugs can also be abused by intravenous administration. In intravenous abuse cases, the adjuvants lactose and sucrose are excreted in urine without hydrolysis to monosaccharides, since there are no disaccharidases in the blood.

The usefulness of point-of-care (POC) tests in screening elevated glucose and ketone body levels postmortem.

The aim was to evaluate the performance of point-of-care (POC) tests in detecting glucose and ketone bodies in postmortem (PM) samples and to assess the usefulness of POC tests in sample screening for more precise analyses. Glucose and ketone body, β-hydroxybutyrate (BHB), were measured from vitreous humor (VH) in 52 autopsy cases with a POC blood glucose monitoring device (BGMD). In addition glucose and ketone bodies, acetone (Ac) and acetoacetate (AcAc), were measured from urine samples in another set of 59 cases with semi-quantitative stick tests.

Renal markers cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) in postmortem samples.

Purpose: Renal markers may provide valuable information for cause of death (CoD) investigation when assessing the influence of impaired kidney function. A commonly used marker, creatinine (Cr), increases due to kidney injury and is known to be reasonably stable in postmortem (PM) samples. More sensitive markers are needed, as the increase of serum Cr level only occurs after relatively severe renal damage.
