The anodic corrosion behavior of 50 Å thick single-crystalline IrO2(110) films supported on slightly bulk-reduced TiO2(110) single crystals is studied during acidic water splitting by a unique combination of operando techniques, namely, synchrotron-based high-energy X-ray reflectivity (XRR) and surface X-ray diffraction (SXRD) together with highly sensitive inductively coupled plasma mass spectrom

To determine the prevalence of renal amyloidosis of the AA-type in a defined population, formalin-fixed specimens from the kidneys of all the cases autopsied in 1983 at The General Hospital of Malmö, Sweden, were investigated using immunohistochemical techniques. Amyloid deposits of protein AA were found in 10 of 1,158 investigated cases and the calculated prevalence was 0.86 per cent. The mean ag

To examine whether sequence-specific antibodies directed against serum amyloid A were useful in the demonstration and classification of amyloidosis, needle biopsy specimens from the kidneys of 152 cases with renal disorders were investigated using the avidin-biotin-peroxidase complex technique of immunohistochemistry. A distinct immunoreactivity of protein AA was seen in biopsies from all 42 indiv

We investigate if Marine Stewardship Council (MSC) certified Norway lobster fishing vessels inSweden got higher prices and sold larger quantities after certification was introduced in 2015. Usingdetailed daily panel data and exploiting the fact that the same fishing water contains both certified andnon-certified vessels, we use a difference-in-difference model for analysing demand effects of MSCce

We investigated the effect of Aztreonam on hydrolysis of β-lactam antibiotics by MBL using New Delhi Metallo-β-lactamase-1(NDM-1) as a model. The results showed that Aztreonam significantly inhibited hydrolysis of Nitrocefin and Meropenem by soluble NDM-1, but also inhibited hydrolysis of Penicillin G by CPG beads immobilized NDM-1(NDM-1 beads). Moreover, in spite of extensive washing for multiple

Polisen bör lära av USA och centralisera sin kamp emot gängkriminaliteten. Ett nationellt centrum med denna huvuduppgift kan vara en början till slutet för gängen, skriver Ardavan Khoshnood som är docent i akutsjukvård vid Lunds universitet samt kriminolog och statsvetare.The police should learn from the United States and centralize their fight against gang criminality. A national center with this main task can be a beginning to the end for the gangs, writes Ardavan Khoshnood who is an associate professor of Emergency Medicine at Lund University and a criminologist and political scientist.

The penicillinase thermistor biosensor（Penicillinase sensor） was developed for the rapid monitoring of blood penem antibiotics concentration and rapid identification of extraneous penicillinase in milk on site.However, the wide application of the penicillinase thermistor biosensor was limited due to its intrinsic poor activity to hydrolyze cephem and carbapenem antibiotics.The recently identified

Objective To compare the enzyme thermistor bioanalysis equipment with blood glucose meter which is analyzed by automatic biochemical analyzer, validate the correct rate of this equipment. The long-term aim of the project was to develop a prototype for a bedside monitor system for semi-continuous monitoring of the blood glucose concentration. This was made possible by using the special advantage of

Methyl parathion hydrolase （ MPH ） as and bovine serum albumin （BSA） as hybrid proteins, the target protein, bovine hemoglobin （BHb）, myoglobin （Mb） enzyme thermal analysis was used to determine the best separation condition of methyl parathion hydrolase through the study of pH and the NaC1 concentration in mobile phase. The results showed that at pH 8.0, NaC1 concentration of 0.8 mol/L, the separ

This chapter describes principles and features of thermal biosensors and microbiosensors and includes a discussion of different thermal transducers. A number of instrumental concepts are described in detail from larger flow injection instruments to miniaturized devices and chip designs with thermal arrays. A thermal–electrochemical hybrid sensor is also presented. The chapter contains many descrip

A biotin-avidin modified biochip has been constructed, and its electrochemistry characteristics were studied with K4Fe(CN)(6).3H2O and ferrocene as the indicators by cyclic voltammograms. Electrochemical experiments showed that this biochip has high response signal, reproducibility,uniformity and low background signal; the ferrocene can be used as high efficiency electron medium. And these results

This paper describes a new protein chip method for detection of single-base mismatches and unpaired bases of DNA, using a genetic fusion molecular system Trx-His6-Linker peptide-Strep-tagII-Linker peptide-MutS (THLSLM). The THLSLM coding sequence was constructed by attaching Strep-tag II and mutS gene to pET32a (+) sequentially with insertion of a linker peptide coding sequence before and behind S

Protein HC (alias alpha 1-microglobulin) contains so far unidentified yellow-brown fluorescent chromophores. Several preparations of human protein HC were extracted with hexane. Most of the extracts contained a substance which, upon reversed-phase HPLC, co-eluted with all-trans- retinol and had an absorption spectrum identical to that of retinol. The substance was also, like retinol, destroyed by

As pointed out in the preceding review (Nachemson and Rydevik 1988), the most serious and common complications of chymopapain treatment of patients with sciatica due to disc herniation are cerebral or subarachnoid hemorrhages and allergic manifestations. Recent progress in biochemical and physiologic studies of cysteine proteinases and their inhibitors allows some speculation on how these complica
