For local administration of drugs or enzyme inhibitors in the human gut, a small-bore, smooth tube was introduced through the nose, retrieved from the pharynx, equipped with a firm radio-opaque capsule, and swallowed. Peristalsis moves the capsule to the desired location in the gut where it is anchored before administration via the tube. Drug uptake is followed by plasma sampling. One capsule typ
Rotational coherent anti-Stokes Raman spectroscopy (CARS) has over the years demonstrated its strong potential to measure temperature and relative concentrations of major species in combustion. A recent work is the development and experimental validation of a CO2 model for thermometry, in addition to our previous rotational CARS models for other molecules. In the,present work, additional calibrati
This paper presents some functional differences as well as similarities observed when comparing the newly discovered cellobiose dehydrogenase (CDH) from Trametes Villosa (T.v) with the well-characterized one from Phanerochaete chrysosporium (P.c.). The enzymes were physically adsorbed on spectrographic graphite electrodes placed in an amperometric flow through cell connected to a flow system. In t
Dampness in buildings has been linked to adverse health effects, but the specific causative agents are unknown. Mycotoxins are secondary metabolites produced by molds and toxic to higher vertebrates. In this study, mass spectrometry was used to demonstrate the presence of mycotoxins predominantly produced by Aspergillus spp. and Stachybotrys spp. in buildings with either ongoing dampness or a hist
Cervical cancer remains a significant public health concern, both at a global and a European level. A number of new technologies such as diagnostic tests for human papillomavirus (HPV) have a potential to assist with the reduction of this disease. However, both the efficacy and the cost-effectiveness of these new technologies must be established in properly designed trials before they can be imple
The determination of drug-protein binding and free drug concentration in plasma applying the equilibrium sampling through membrane (ESTM) technique has been studied using supported liquid membrane extraction in a single hollow fibre without any membrane carrier. In the extraction setup, the donor phase (plasma or buffer) was placed in the vial, into which was immersed the hollow fibre with the acc
The genetic variation of Duddingtonia flagrans, which has become a promising biocontrol agent of animal parasitic nematodes, was investigated in a worldwide collection of 22 isolates. We analysed the sequence variation in four nuclear genes, tubA (beta-tubulin), CMD1 (calmodulin), EF1alpha (translation elongation factor 1alpha), and PII (extracellular serine protease). 1428 aligned base pairs (bp)
Experiments were performed in the temperature range of 294 - 1143 K in pure CO2 using high-resolution rotational coherent anti-Stokes Raman spectroscopy (CARS), in the dual-broadband approach. Experimental single-shot spectra were recorded with high spectral resolution using a single-mode Nd:YAG laser and a relay imaging lens system on the exit of a 1 m spectrometer. A theoretical rotational CARS
The object of this study was to investigate whether exposure of pipe-layers to thermal degradation products of diphenylmethane diisocyanate (MDI) could be assessed by analysing 4,4-methylenedianiline (MDA) in hydrolysed plasma and urine, and whether the genotype for N-acetylation affected these biomarker levels. Blood and urine samples were drawn from 30-pipe-layers who had been welding polyuretha
BACKGROUND: There is little consensus on a standard approach to analysing bone scan images. The Bone Scan Index (BSI) is predictive of survival in patients with progressive prostate cancer (PCa), but the popularity of this metric is hampered by the tedium of the manual calculation. OBJECTIVE: Develop a fully automated method of quantifying the BSI and determining the clinical value of automated
Depression and anxiety disorders are increasing among the general population in the Western world. Individuals may need several kinds of treatment in order to maintain health, such as cognitive behavioural therapy (CBT) and drug treatment. However, having an everyday life that "works" is also important, suggesting a need for interventions based on activities that facilitate a satisfying everyday l
BACKGROUND: Anaemia is a common complication of chemotherapy. As anaemia can lead to e.g. fatigue, depression, social isolation and chest pain it diminishes physical capacity and quality of life. It is generally accepted that symptomatic anaemia should be corrected. Treatment options include red blood cell transfusion (RBCT), erythropoietin (EPO) administration or a combination of both. OBJECTIVE:
The wage book of a Derbyshire farm, which includes payments to laborers for 1772 to 1775 and 1831 to 1845, allows me to examine the employment patterns of male and female day-laborers at this farm before and after important innovations in agriculture. I find a fall in relative female employment which appears to be due to a fall in demand. Male employment shifted to the spring, but female employmen
Fragrance production in petunia flowers is highly regulated. Two transcription factors, ODORANT1 (ODO1) and EMISSION OF BENZENOIDS II (EOBII) have recently been identified as regulators of the volatile benzenoid/phenylpropanoid pathway in petals. Unlike the non-fragrant Petunia hybrida cultivar R27, the fragrant cultivar Mitchell highly expresses ODO1. Using stable reporter lines, we identified th
Background: Oral anticoagulation therapy is recommended for the prevention of recurrent ischemic stroke in patients with atrial fibrillation (AF). Current guidelines do not provide evidence-based recommendations on optimal time-point to start anticoagulation therapy after an acute ischemic stroke. Non-vitamin K antagonist oral anticoagulants (NOACs) may offer advantages compared to warfarin becaus
This paper examines demand for and access to private-sector extension services by contracted cotton producers in northern Tanzania. Data from a non-random survey of 520 smallholders show that only 21.9% received any extension and only 4.6% received extension from the cotton ginnery. Wealthier households were three times more likely to receive extension from any provider. While the public sector re
