Pain outcomes after surgery in patients with intramedullary spinal cord cavernous malformations
Authors: Deutsch Harel 
Published: September 2010

Object
The objective of the study was to quantify the improvement in pain levels for patients who have undergone surgery for intramedullary spinal cord cavernous malformations (SCCMs).

Methods
The author reviewed medical records of patients who underwent surgery for an intramedullary SCCM between 2003 and 2010. Numerical pain scores (range 0–10) were recorded preoperatively and at follow-up. The follow-up period exceeded 1 year. Neurological status and subjective outcomes were assessed. Each patient underwent follow-up MR imaging.

Results
Five patients were identified with SCCMs who underwent surgery: 4 with thoracic and 1 with cervical lesions. Patients had been conservatively managed for an average of 5 years prior to surgery, and none had a history of acute hemorrhage or neurological deterioration during the observation period. The primary indication for surgery in each patient was pain, although 4 of 5 patients had some evidence of myelopathy on examination. Pain improved from a mean preoperative score of 8.6 to mean score of 2.0 (p < 0.01) at 1 month. Pain scores then increased to 3.7 (p < 0.01) at 1 year. All patients had some improvement in pain. No new motor weakness was noted, but all patients had increased symptoms of posterior-column dysfunction and numbness after surgery.

Conclusions
Spinal cord intramedullary cavernous malformations are increasingly being diagnosed early with patients presenting with mostly pain symptoms. Removal of the lesion is reliably associated with improvement in pain scores but often the pain improvement is transient. While long-term worsening of pain scores occurs, at 1-year follow-up, patients reported pain scores were improved over preoperative scores. In all patients some degree of postoperative posterior-column dysfunction was present. Some of the immediate pain relief may be due to analgesia related to the myelotomy of newly described posterior column pain pathways. In patients with severe pain, surgery to remove SCCMs reduced the overall pain level at 1 year.

Published: September 2010

Three new Schiff base rhodium (III) complexes, derived from three ligands, L1, L2 and L3 have been prepared and characterized by IR, 1HNMR, mass spectra and the elemental analysis. These complexes have shown efficient catalytic activity in the transfer hydrogenation of wide variety ketones to the corresponding alcohols in formic acid/triethylamine solution under mild reaction conditions. Depending on the ketone, the percentage of conversion for RhL1 have been found to be (51-92%) compared to RhL2 which had a yield of (42-92%) while for RhL3 (71-94%), within time range of 0.5-12 hrs.

Published: September 2010

A simple and fast synthesis method of gold and silver nanoparticles without any surfactant or reducing agent has been developed by using the extract of green tea (camellia sinensis) under microwave irradiation. The synthesized gold and silver colloidal nanoparticles were spherical in shape and have an average diameter of 13 and 17 nm for Au and Ag nanoparticles, respectively. The as-synthesized nanoparticles were characterized by TEM, XRD, XPS, and UV-visible spectroscopy.Keywords: Microwave; Gold; Silver; Nanoparticles; Biosynthesis. © 2010 JSR Publications.

Published: September 2010

Purpose. Determine if recruitment methods are differentially related to the reach of a physical activity program in metro/urban vs. rural settings. Design. Cross-sectional survey. Setting. Kansas counties. Subjects. Ninety-four Cooperative Extension agents responsible for 102 counties. Measures. Promotional score, task force activity, and years of program delivery were assessed using a self-report survey. Reach was assessed for each county by dividing the number of participants by intended population using census data. Analysis. Rural/urban comparisons on reach were completed using a Mann-Whitney test. Multiple linear regression models were used to determine the relationship between independent variables and participation rate by setting type. Results. Metro/urban counties had lower mean participation rates than rural counties (z = −4.5; p < .001). In metro/urban counties, the regression on participation rate was significant (R2 = .19; F = 4.09; p = .011), but only promotional score significantly contributed to the model (p = .003). In rural counties, the regression was also significant (R2 = .34; F = 6.64; p = .001), with task force activity and years of delivery making significant contributions (p = .001 and p = .017, respectively). Conclusion. Interpersonal methods may be more effective in recruiting physical activity program participants in rural settings, whereas using a greater variety of promotional methods may be more effective in metro/urban settings.

Purpose: To examine the influence of a tobacco-free hospital campus (TFHC) policy on employee smoking behavior. Design: Questionnaires immediately prior to, 6 months after, and 1 year after implementation of a TFHC policy. Setting: University-affiliated hospital system. Subjects: A cohort of smokers and recent quitters. Measures: Smoking status, quit attempts, influence of TFHC policy. Analysis: Descriptive. Results: From 2024 employees who responded to an initial online survey prior to implementation of a TFHC policy, 307 respondents reported either current smoking or quitting smoking within the past 6 months. Of these, 210 (68%) agreed to follow-up surveys at 6 and 12 months post-policy implementation. At each of the three times, between 15% and 18.5% of the cohort reported not smoking, with at least 48% of those not smoking reporting 6 to 12 months continuous abstinence. Sixty percent or more of those who reported quit attempts or not smoking indicated that the TFHC policy was influential in their efforts. Conclusions: A TFHC policy may lead to increased employee smoking quit attempts and successful cessation. Health care facilities should broaden smoking restrictions to include the entire workplace campus, not only to reduce exposure to environmental tobacco smoke, but also to increase tobacco cessation.

Sequencing batch reactor technology for biological wastewater treatment: a review
Authors: Singh Mohini , Srivastava R. K. 
Published: September 2010

AbstractWastewater treatment has been a challenge throughout the years due to varying influent characteristics and stringent effluent regulations. In response to this dilemma, a reliable, cost‐effective and high‐efficiency sequencing batch reactor (SBR) technology has been recently developed. SBRs are variations of the activated sludge process that operates on a fill‐and‐draw basis. It combines both aerobic–anaerobic phases in one unit and saves up to 25% of the aeration costs concomitant with low sludge production. Consequently, simultaneous nitrogen and phosphorus removal from the wastewater could be achieved by adjusting the actual operating cycle. This review paper discusses the technical description and operational flexibility of SBR for the treatment of wide range of effluent under different operational conditions, together with its modifications that could increase the effectiveness of SBR systems in the future.

Published: September 2010

AbstractExperimental investigations aimed at assessing the effectiveness of femtosecond (FS) laser ablation for creating microscale features on electrospun poly(ε‐caprolactone) (PCL)/gelatin nanofiber tissue scaffold capable of controlling cell distribution are described. Statistical comparisons of the fiber diameter and surface porosity on laser‐machined and as‐spun surface were made and results showed that laser ablation did not change the fiber surface morphology. The minimum feature size that could be created on electrospun nanofiber surfaces by direct‐write ablation was measured over a range of laser pulse energies. The minimum feature size that could be created was limited only by the pore size of the scaffold surface. The chemical states of PCL/gelatin nanofiber surfaces were measured before and after FS laser machining by attenuated total reflectance Fourier transform infrared (ATR‐FTIR) spectroscopy and X‐ray photoelectron spectroscopy (XPS) and showed that laser machining produced no changes in the chemistry of the surface. In vitro, mouse embryonic stem cells (mES cells) were cultured on as‐spun surfaces and in laser‐machined microwells. Cell densities were found to be statistically indistinguishable after 1 and 2 days of growth. Additionally, confocal microscope imaging confirmed that spreading of mES cells cultured within laser‐machined microwells was constrained by the cavity walls, the expected and desired function of these cavities. The geometric constraint caused statistically significant smaller density of cells in microwells after 3 days of growth. It was concluded that FS laser ablation is an effective process for microscale structuring of these electrospun nanofiber tissue scaffold surfaces. Biotechnol.

Published: September 2010

AbstractLong‐term primary cultures of hepatocytes are essential for bioartificial liver (BAL) devices and to reduce and replace animal tests in lead candidate optimization in drug discovery and toxicology tests. The aim of this work was to improve bioreactor cultures of hepatocyte spheroids by adding a more physiological perfusion feeding regime to these bioreactor systems. A continuous perfusion feeding was compared with 50% medium replacement (routinely used for in vitro tests) at the same dilution rate, 0.125 day−1, for three operative weeks. Perfusion feeding led to a 10‐fold improvement in albumin synthesis in bioreactors containing non‐encapsulated hepatocyte spheroids; no significant improvement was observed in phase I drug metabolizing activity. When ultra high viscous alginate encapsulated spheroids were cultured in perfusion, urea synthesis, phase I drug metabolizing activity and oxygen consumption had a threefold improvement over the 50% medium replacement regime; albumin production was the same for both feeding regimes. The effective diffusion of albumin in the alginate capsules was 7.75.10−9 cm2 s−1 and no diffusion limitation for this protein was observed using these alginate capsules under our operational conditions. In conclusion, perfusion feeding coupled with alginate encapsulation of hepatocyte spheroids showed a synergistic effect with a threefold improvement in three independent liver‐specific functions of long‐term hepatocyte spheroid cultures.

Structure–Activity Relationships of Oligocationic, Ammonium‐Functionalized Triarylphosphines as Ligands in the Pd‐Catalyzed Suzuki–Miyaura Reaction

Published: September 2010

AbstractA series of oligocationic triarylphosphine ligands, containing a varying number (from 2 to 6) of meta‐ammoniomethyl substituents, have been synthesized, characterized, and tested as ligands in the Pd‐catalyzed Suzuki–Miyaura cross‐coupling reaction. By systematic catalytic investigations and spectroscopic (NMR and UV/Vis) studies of these ligands in the palladium(0) complexes as well as of their neutral amine analogues and of triphenylphosphine, structure–activity relations have been established. The substitution of a triarylphosphine core with cationic meta‐ammoniomethyl substituents increases the steric demand (cone angle) of the phosphine ligand and decreases its σ‐donation strength. Furthermore, Coulombic inter‐ligand repulsion forces are introduced. The catalytic activity in the Suzuki–Miyaura reaction within this class of ligands is governed by the number of cationic charges in the ligand structure, rather than by their steric properties or their σ‐donating strength. With an increasing number of charges, the preference for the formation of coordinatively unsaturated phosphine–palladium species increases, which leads to a higher catalytic activity through faster catalyst activation.
