An Integrated Thermal Sensor Array For Multianalyte determination demonstrated With Glucose, Urea And Penicillin

An integrated thermal biosensor array was designed and fabricated for the simultaneous determination of glucose, urea and penicillin. The sensor contains ten thin-film thermistors which were fabricated on quartz chip by micromachining and semiconductor technologies. This sensor allows to determine maximum five different analytes nearly simultaneously by serially dividing the single microchannel in

The liver-first approach for synchronous colorectal liver metastases: A systematic review and meta-analysis of completion rates and effects on survival

Background: Patients presenting with synchronous colorectal liver metastases are increasinglybeing considered for a curative treatment, and the liver-first approach is gaining popularity in thiscontext. However, little is known about the completion rates of the liver-first approach and itseffects on survival.Methods:A systematic review and meta-analysis of liver-first strategy for colorectal liver

Miniaturized thermal biosensors

A summary of our efforts to develop miniaturized biosensors based on the enzyme thermistor is presented. Three constructions are described. The work focuses on the measurement of glucose in whole blood.The first biosensor was used to analyze concentrated and tenfold diluted blood samples. The glucose concentration obtained using this construction correlated well with the reference method.Using the

A Microarray platform for "omics" analysis

Microarray technology has revolutionized genetic analysis. However, limitations in genome analysis has lead to renewed interest in establishing 'omic' strategies. As we enter the post-genomic era, new microarray technologies are needed to address these new classes of 'omic' targets, such as proteins, as well as lipids and carbohydrates. We have developed a microarray platform that combines self- a

Reconsidering regional structural conditions for industrial renewal

This article develops a more comprehensive understanding of innovation-based renewal of industries from a structural perspective. Arguably, established perspectives offer rather simplistic views, portraying structures as either enabling or constraining for certain forms of regional industrial change. Inspired by work in organizational institutionalism on ‘institutional infrastructures’, this artic

Sverige och den västeuropeiska arbetslösheten 1970-1990

This dissertation studies the labor market development of fourteen Western European countries during the years 1970-90, focusing on the relatively low Swedish unemployment. The variation in unemployment over time and between countries has proved difficult to explain with the most influential theoretical models, which are usually categorized as New-keynesian and Post-keynesian respectively. The dis

Vintergatan - i. The origins of chemically, kinematically, and structurally distinct discs in a simulated milky way-mass galaxy

Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical, and kinematical structures that encode its history. In this work, we study their origins using a cosmological zoom simulation, VINTERGATAN, of a MilkyWay-mass disc galaxy. We find that in connection to the last major merger at z ∼ 1.5, cosmological accretion leads to the rapid formation of an outer, metal-poor, low-[α/

4MOST : The 4-metre Multi-Object Spectroscopic Telescope project at preliminary design review

We present an overview of the 4MOST project at the Preliminary Design Review. 4MOST is a major new wide-field, high-multiplex spectroscopic survey facility under development for the VISTA telescope of ESO. 4MOST has a broad range of science goals ranging from Galactic Archaeology and stellar physics to the high-energy physics, galaxy evolution, and cosmology. Starting in 2021, 4MOST will deploy 24

Quest for the Sun's siblings based on elemental abundances

We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Technique of chemical tagging gives us a high probability that four stars might be from the same open cluster. Only one candidate HIP 40317 which has solar metallicity and age could be a solar sibling. We performed simulations of the Sun's birth

The protein HC chromophore is linked to the cysteine residue at position 34 of the polypeptide chain by a reduction-resistant bond and causes the charge heterogeneity of protein HC

Protein HC, an extremely charge-heterogeneous lipocalin, carries a yellow-brown fluorescent chromophore of unknown structure covalently bound at an unidentified site of its polypeptide chain. Two chromophore-carrying peptides with 60% of the chromophore material (defined as material absorbing light at 330 nm) were isolated from pepsin-digested native human protein HC by reversed-phase high perform

Imiquimod shows anti-viral actions in human bronchial epithelium - implications for COVID-19 treatment

Combining anti-viral and anti-inflammatory effects in a single drug may be beneficial in treating COVID-19. We hypothesized that the TLR7 agonist imiquimod (imq) may exert these actions in human bronchial epithelial cells (HBECs), which are targets in SARS-CoV-2 mediated lung injury. Methods: Using primary HBECs from asthmatic donors (N=18), we explored actions of imq related to airway viral resis

Diagnostic value of analysis of cystatin C and protein HC in biological fluids

Cystatin C, a 13 kDa-protein, is produced by most nucleated cells and is catabolized by the renal tubular cells after passing the glomerular filter. It belongs to the family 2 of the cystatin superfamily of proteins. The function of cystatin C is to regulate the activity of cysteine proteinases and cystatin C seems to be the main cysteine proteinase inhibitor of most investigated human biological
