Is epineurectomy necessary in the surgical management of carpal tunnel syndrome?

WOS: 000395404700015PubMed: 28091439Background: In this study, it was aimed to determine whether median nerve epineurectomy is beneficial in the surgical management of carpal tunnel syndrome (CTS). Materials and Methods: The study enrolled 72 patients including 34 patients without epineurectomy (Group A) and 38 patients with epineurectomy (Group B). Surgery was performed in patients with severe electrodiagnostic CTS findings, CTS duration >1 year and flattening along with hypervascularization in median nerve. All patients were assessed by visual analog scale, two-point discrimination test as well as subjective and objective findings at baseline and on the months 1, 3, and 6 after surgery. Results: The mean age was 58.3 years (42-75 years) in 38 patients who underwent an epineurectomy, whereas it was 61.5 years (41-82 years) in 34 patients who did not have an epineurectomy. The groups were similar with regard to age, gender, duration of symptoms, and preoperative physical findings. Mean visual analog scale (VAS) scores were 1.7 in Group A and 1.8 in Group B. Again, these differences were not significant, on physical examination, the average two-point discrimination in the distribution of the median nerve was 4.9 mm (range: 3-11 mm) in Group A and 5.3 mm (range: 3-10 mm) in Group B. In postoperative evaluations, there was a better improvement in visual analog scale scores, two-point discrimination test and subjective symptoms including dysesthesia, pain and nocturnal pain within first 3 months; however, there was no marked difference in objective and subjective findings on the 6th month. No complication or recurrence was observed. Conclusion: We believe that median nerve epineurectomy is unnecessary in the surgical management of primary CTS since it has no influence on the midterm outcomes

Frequency domain analysis of UWB dipole arrays

In this paper, behavior of dipole arrays for Ultra-Wideband (UWB) signals is investigated using an approach in the frequency domain. Energy formulas and correlation coefficient expressions are derived for an array of thin dipoles at the transmitting side and one dipole at the receiving side. Beam-scanning characteristics of UWB dipole arrays are also investigated in the same manner. Different element lengths are used in the array to improve the detection and beam-scanning capabilities. Derived frequency domain expressions can easily be evaluated numerically, allowing us to obtain reasonably accurate results. This approach which is an alternative to numerical methods in time domain serves as a different viewpoint and will be a significant step to make progress in UWB antenna design. © 2014 © 2014 Taylor & Francis

UWB dipole array with equally spaced elements of different lengths

2007 IEEE International Conference on Ultra-Wideband, ICUWB --24 September 2007 through 27 September 2007 -- --This study analyses radiation and reception characteristics of UWB antennas for an array of equally spaced dipoles of different lengths at the transmitter and a single dipole at the receiver. Radiated energy from the array of dipoles and received energy by the load at the terminals of the receiving dipole are calculated. Correlation coefficient between the load voltage and source pulse is investigated to examine the detection characteristics at the receiver. Effect of changing different array parameters such as element spacing and number of elements are presented. The analysis is performed in the frequency domain providing a new perspective for the design considerations of UWB antennas. © 2007 IEEE

Synthesis and spectroscopic studies of homo-binuclear, alkoxo bridged homo- and hetero-tetranuclear metal complexes of a bis-N 2O 4 Schiff base ligand derived from ethanolamine and macroacyclic tetranaphthaldehyde

PubMed: 21550297Three new homo-binuclear Ni(II), Cu(II), Zn(II) complexes (2-4), homo-tetranuclear Cu(II) complex (5), and hetero-tetranuclear Cu(II)-Ni(II) complex (6) of a macroacyclic potentially bis-hexadentate N 2O 4 Schiff base have been synthesized. The imino-alcohol ligand, H 4L was obtained by the condensation of ethanolamine with 2,2?-[2,3-bis(1-formyl-2-naphthyloxymethyl)-but-2-ene-1,4-diyldioxy] bis(naphthalene-1-carbaldehyde). The structures of both the Schiff base and its complexes have been proposed by elemental analyses, spectroscopic data i.e. IR, 1H and 13C NMR, UV-vis, electrospray ionisation mass spectra, molar conductivities and magnetic susceptibility measurements. The ligand has two similar compartments to bind first primary two metal ions, and acts bi- or tetra-negative, bis-tetradentate forming five membered chelate ring. However, secondary two metal ions (either Cu 2+ or Ni 2+) are ligated with dianionic oxygen atoms of the alcohol groups and are linked to the 1,10-phenanthroline-nitrogen atoms in the tetranuclear complexes (5 and 6). © 2011 Elsevier B.V.

Bistatic scattering from vegetation canopy in millimeter waves

62nd ARFTG Microwave Measurements Conference, ARFTG 2003 --4 December 2003 through 5 December 2003 -- --In this paper mm wavelength is used to understand the behavior of vegetation canopy. In remote sensing studies, which can be thought as a part of GIS, vegetation canopies and their frequency dependent behaviors are important. Although, the mm waves were used in this study, frequency takes place between optic and infrared bands were also used. On the other hand, larger penetration depth of millimeter waves relative to optics can supply extra information about soil contributions to vegetation canopies. The backscattering mechanism is related to physical parameters of canopies. These physical parameter are water contamination of single elements and soil covered by canopy. The results show that volumetric moisture content of soil contribution plays an important role in scattering phenomena of canopies

The utility of GFP in genetic engineering of horticultural plants

Reporter proteins play a significant role in developing and optimizing transformation protocols for plant species and they show a unique activity to visualize gene expression and protein localization. Chemical based selection for plant transformation is associated with a number of problems that might be avoided through visual selection. In recent years, the reporter protein GFP (Green Fluorescent Protein) has become very effective and highly valuable for use in biotechnology, cell biology, and biochemistry. It is a unique tool for monitoring gene expression, protein localization, detection of the gene flows and protein dynamics in both prokaryotic and eukaryotic living cells because it requires neither exogenous substrates nor cofactors for its activity. We discussed the use of jellyfish green fluorescent protein (GFP) as a reporter in horticultural plants. © Verlag Eugen Ulmer GmbH & Co
