Purpose: The aim of the study was to evaluate the effect of perioperatively systemically administered betamethasone on nerve recovery (within or outside a confined space) after induced nerve crush injury. Materials and Methods: The sciatic nerve of 40 adult Wistar rats was crushed. In half of the animals, the injured nerve was entrapped in a silicone tube to simulate the environment of a closed sp
Wettability is a fundamental property of a solid surface, which plays important roles in many industrial applications. The possibility to create well-controlled nonwetting states on silicon surfaces without photolithography-based processing can bring many advantages in the biotechnology and microfluidics areas. In this paper, superhydrophobic properties of macroporous–nanoporous structured silicon
The pseudo-spectra (or spectral instability) of non-selfadjoint operators is a topic of current interest in applied mathematics. For example, in computational fluid dynamics it affects the study of the stability of laminar flows. In fact, even for the most basic flows, the computations entirely fails to predict what is observed in the experiments. The explanation is that for non-normal operators
1 During 1989-93, field studies were conducted in Finland to develop a method based on pheromone traps to monitor and forecast population levels of the European pine sawfly (Neodiprion sertifer Geoffr.) and tree defoliation. 2 Three traps per site were baited with 100 mu g of the N. sertifer sex pheromone, the acetate ester of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol), in maturing pine s
The complexation between a polyion and an oppositely charged spherical macroion in the framework of the primitive model has been studied by the use of Monte Carlo simulations. The polyion length, linear charge density, and bare persistence length are varied systematically, while the properties of the macroion are kept constant. The polyion charge to macroion charge ratio is varied between 1/4 and
Studier i svensk språkhistoria 8 är en rapport från konferensen Svenska språkets historia 8 som avhölls i Lund 21-22 maj 2004. Temat för konferensen var Språkförändring på olika nivåer i språket. Tanken var att fokusera på språkförändringsmekanismer i ett brett perspektiv och på alla språkliga nivåer. I detta syfte hade konferensen fyra plenarföreläsningar; en vardera inom fonologi, lexikon, synta
Twenty-eight children with attention-deficit hyperactivity disorder (ADHD) were examined with SPECT (single photon emission computed tomography). Seven of the children had abnormal distribution of the regional cerebral blood-flow (rCBF) on visual evaluation and 10 had abnormal EEG findings. The only clinical finding that differentiated the group with normal from abnormal rCBF was behaviour symptom
The pH dependencies of the UV-vis and fluorescent spectra of new water-soluble dendritic porphyrins and tetrabenzoporphyrins were studied. Because of extended -conjugation and nonplanar distortion, the absorption and the emission bands of tetraaryltetrabenzoporphyrins (Ar4TBP) are red-shifted and do not overlap with those of regular tetraarylporphyrins (Ar4P). When encapsulated inside dendrimers w
The 13-amino acid glycopeptide tx5a (Gla-Cys-Cys-Gla-Asp-Gly-Trp*-Cys-Cys-Thr*-Ala-Ala-Hyp-OH, where Trp* = 6-bromotryptophan and Thr* = Gal-GalNAc-threonine), isolated from Conus textile, causes hyperactivity and spasticity when injected intracerebral ventricularly into mice. It contains nine post-translationally modified residues: four cysteine residues, two gamma-carboxyglutamic acid residues,
We report tunneling spectroscopy measurements of the Zeeman spin splitting in InAs few-electron quantum dots. The dots are formed between two InP barriers in InAs nanowires with a wurtzite crystal structure grown using chemical beam epitaxy. The values of the electron g factors of the first few electrons entering the dot are found to strongly depend on dot size. They range from close to the InAs b
The purpose of this study is to assess QT interval measurements from the EASI 12-lead ECG as compared to the standard 12-lead ECG. The QT interval was automatically measured in simultaneously recorded standard and EASI 12- lead ECGs, using a validated wavelet-based delineator. The agreement between the two sets of measurements was quantified both on a lead-by-lead basis and a multilead basis. The
