Structure‐Directing Forces in Intercluster Compounds of Cationic [Ag14(CCtBu)12Cl]+ Building Blocks and Polyoxometalates: Long‐Range versus Short‐Range Bonding Interactions
Authors: Gruber Franziska , Schulz‐Dobrick Martin , Jansen Martin
Published: January 2010

Crystallization of [Ag14(CCtBu)12Cl][BF4] and different polyoxometalates in organic solvents yields a series of new intercluster compounds: [Ag14(CCtBu)12Cl(CH3CN)]2[W6O19] (1), (nBu4N)[Ag14(CCtBu)12Cl(CH3CN)]2[PW12O40] (2), and [Ag14(CCtBu)12Cl]2[Ag14(CCtBu)12Cl(CH3CN)]2[SiMo12O40] (3). Applying the same technique to a system starting from polymeric {[Ag3(CCtBu)2][BF4]⋅0.6 H2O}n and the polyoxometalate (nBu4N)2[W6O19] results in the formation of [Ag14(CCtBu)12(CH3CN)2][W6O19] (4). Here, the Ag14 cluster is generated from polymeric {[Ag3(CCtBu)2][BF4]⋅0.6 H2O}n during crystallization. In a similar way, [Ag15(CCtBu)12(CH3CN)5][PW12O40] (5) has been obtained from {[Ag3(CCtBu)2][BF4]⋅0.6 H2O}n and (nBu4N)3[PW12O40]. The use of charged building blocks was intentional, because at these conditions the contribution of long‐range Coulomb interactions would benefit most from full periodicity of the intercluster compound, thus favoring formation of well‐crystalline materials. The latter has been achieved, indeed. However, as a most conspicuous feature, equally charged species aggregate, which demonstrates that the short‐range interactions between the “surfaces” of the clusters represent the more powerful structure direction forces than the long‐range Coulomb bonding. This observation is of significant importance for understanding the mechanisms underlying self‐organization of monodisperse and structurally well‐defined particles of nanometer size.

About color rendition of light sources: The balance between simplicity and accuracy
Authors: van der Burgt Peter , van Kemenade Johan
Published: January 2010

Most descriptions of the color‐rendering properties of light sources are based on the calculation of color differences for a number of test colors between the light source and a reference source. The CIE color‐rendering index (CRI) is a single number based on the average color difference for eight test colors. Ever since its introduction the CRI has been discussed and several suggestions have been made to improve the description of the CRI such as color preference index, color appearance data and color discrimination index. New lighting technologies such as LEDs can have spectral power distributions consisting of narrow spectral bands in the red, green and blue region of the spectrum. There are indications that the CRI does not always provide a reliable description of the color‐rendering properties of these LED based light sources.

In this article the principal elements of the CRI calculation are analyzed and their influence on the color‐rendering description will be discussed. The focus of the analysis has been on the selection of object colors. Principally the color‐rendering description of a light source should not depend on the set of colors chosen for the calculation. From our analysis requirements for such color sets are given. © 2010 Wiley Periodicals, Inc. Col Res Appl, 2010
Proximal‐type epithelioid sarcoma of the maxilla with metastasis to the scalp: Cytologic findings of an unusual malignant tumor
Authors: Uschuplich Vedran , Gadre Swarupa A. , Debski Robert F. , Sahoo Sunati
Published: January 2010

Epithelioid sarcoma of proximal type (ESPT), a subtype of epithelioid sarcoma, is an uncommon malignant neoplasm of the soft tissue with histo‐ and cytologic features similar to epithelioid sarcoma, classic type and to the more commonly encountered extra‐renal malignant rhabdoid tumor (EMRT). Unlike classic epithelioid sarcoma, ESPT usually involves pelvic, perineal, and genital regions and has an aggressive clinical course. Like EMRT, ESPT can have aberrations of the INI1 gene on chromosome 22q, which results in the loss of INI1 protein expression. We describe here the cytological findings of an ESPT metastatic to the scalp in a 14‐year‐old boy. Cytological preparations showed a discohesive population of pleomorphic ovoid to polygonal cells with large irregular nuclei and prominent nucleoli. Isolated cells with rhabdoid features were noted. These cells had abundant cytoplasm and occasional intracytoplasmic hyaline inclusions. In the light of the patient's clinical history of a known primary ESPT of the maxilla, the cytologic features were distinct enough to render a diagnosis of a metastatic lesion to the skull. Diagn.

The persistent congestion problem of FAST‐TCP: analysis and solutions
Authors: Rodríguez‐Pérez M. , Herrería‐Alonso S. , Fernández‐Veiga M. , López‐García C.
Published: January 2010

FAST‐TCP achieves better performance than traditional TCP‐Reno schemes, but unfortunately it is inherently unfair to older connections due to wrong estimations of the round‐trip propagation delay.

This paper presents a model for this anomalous behaviour of FAST flows, known as the persistent congestion problem. We first develop an elementary analysis for a scenario with just two flows, and then build up the general case with an arbitrary number of flows. The model correctly quantifies how much unfairness shows up among the different connections, confirming experimental observations made by several previous studies.

We built on this model to develop an algorithm to obtain a good estimate of the propagation delay for FAST‐TCP that enables to achieve fairness between aged and new connections while preserving the high throughput and low buffer occupancy of the original protocol. Furthermore, our proposal only requires a modification of the sender host, avoiding the need to upgrade the intermediate routers in any way. Copyright © 2010 John Wiley & Sons, Ltd.

Since bone resorption and formation by continuous and intermittent parathyroid hormone (PTH) treatments involve various types of cells in bone, this study examined the underlying mechanism by combining culture systems using mouse primary calvarial osteoblasts and bone marrow cells. The PTH/PTHrP receptor (PTH1R) expression and the cAMP accumulation in response to PTH were increased in accordance with the differentiation of osteoblasts. Osteoclast formation was strongly induced by continuous PTH treatment in the monolayer co‐culture of osteoblasts and bone marrow cells, which was associated with RANKL expression in differentiated osteoblasts. Bone formation determined by ALP activity and the type I collagen mRNA expression was stimulated by intermittent PTH treatment in the monolayer co‐culture and in the bone marrow cell layer of the separated co‐culture in a double chamber dish, but not in the culture of bone marrow cells alone. The stimulation in the separated co‐culture, accompanied by IGF‐I production by osteoblasts, was abolished when bone marrow cells were derived from knockout mice of insulin‐receptor substrate‐1 (IRS‐1−/−) or when osteoblasts were from PTH1R−/− mice. We conclude that differentiated osteoblasts are most likely the direct target of both continuous and intermittent PTH, while bone marrow cells are likely the effector cells. The osteoblasts stimulated by continuous PTH express RANKL which causes osteoclastogenesis from the precursors in bone marrow via cell‐to‐cell contact, leading to bone resorption; while the osteoblasts stimulated by intermittent PTH secrete IGF‐I which activates IRS‐1 in osteoblast precursors in bone marrow via a paracrine mechanism, leading to bone formation.

Sex differences in behavior, morphology, and physiology are common in animals. In many bird species, differences in the feather colors of the sexes are apparent when judged by human observers and using physical measures of plumage reflectance, cryptic (to human) plumage dichromatism has also been detected in several additional avian lineages. However, it remains to be confirmed in almost all species whether sexual dichromatism is perceivable by individuals of the studied species. This latter step is essential because it allows the evaluation of alternative hypotheses regarding the signaling and communication functions of plumage variation. We applied perceptual modeling of the avian visual system for the first time to an endemic New Zealand bird to provide evidence of subtle but consistent sexual dichromatism in the whitehead, Mohoua albicilla. Molecular sexing techniques were also used in this species to confirm the extent of the sexual size dimorphism in plumage and body mass. Despite the small sample sizes, we now validate previous reports based on human perception that in male whiteheads head and chest feathers are physically brighter than in females. We further suggest that the extent of sexual plumage dichromatism is pronounced and can be perceived by these birds. In contrast, although sexual dimorphism was also detectable in the mass among the DNA‐sexed individuals, it was found to be less extensive than previously thought. Sexual size dimorphism and intraspecifically perceivable plumage dichromatism represent reliable traits that differ between female and male whiteheads. These traits, in turn, may contribute to honest communication displays within the complex social recognition systems of communally breeding whitehead and other group‐breeding taxa. J.

Penetration depth method—novel real‐time strategy for evaluating femoroacetabular impingement
Authors: Arbabi Ehsan , Chegini Salman , Boulic Ronan , Tannast Moritz , Ferguson Stephen J. , Thalmann Daniel
Published: January 2010

We introduce a new method for computerized real‐time evaluation of femoroacetabular impingement (FAI). In contrast to previously presented stress analyses, this method is based on two types of predictions of penetration depths for two rotating bodies: curvilinear and radial penetration depth. This intuitive method allows the analysis of both bony and soft tissue structures (such as cartilage and acetabular labrum) in real time. Characteristic penetration depth patterns were found for different subtypes of FAI, such as cam and pincer pathologies. In addition, correlation between the penetration depths (estimated by applying this method) and the existing contact stresses (estimated by applying the finite element method) of various hip morphologies were found. A strong correlation with predicted stress values existed, with a mean correlation coefficient of 0.91 for the curvilinear and 0.80 for the radial penetration method. The results show that the penetration depth method is a promising, fast, and accurate method for quantification and diagnosis of FAI. © 2010 Orthopaedic Research Society.

Published: January 2010

This study tested the effects of variable‐stiffness shoes on knee adduction moment, pain, and function in subjects with symptoms of medial compartment knee osteoarthritis over 6 months. Patients were randomly and blindly assigned to a variable‐stiffness intervention or constant‐stiffness control shoe. The Western Ontario and McMaster Universities (WOMAC) score served as the primary outcome measure. Joint loading, the secondary outcome measure, was assessed using the external knee adduction moment. Peak external knee adduction moment, total WOMAC, and WOMAC pain scores were assessed at baseline and after 6 months. The total WOMAC and WOMAC pain scores for the intervention group were reduced from baseline to 6 months (p = 0.017 and p = 0.002, respectively), with no significant reductions for the control group. There was no difference between groups in magnitude of the reduction in total WOMAC (p = 0.50) or WOMAC pain scores (p = 0.31). The proportion of patients achieving a clinically important improvement in pain was greater in the intervention group than in the control group (p = 0.012). The variable‐stiffness shoes reduced the peak knee adduction moment (−6.6% vs. control, p < 0.001) in the 34 intervention subjects at 6 months. The adduction moment reduction significantly improved (p = 0.03) from the baseline reduction. The constant‐stiffness control shoe increased the peak knee adduction moment (+6.3% vs. personal, p = 0.004) in the 26 control subjects at 6 months. The results of this study showed that wearing the variable‐stiffness shoe lowered the adduction moment, reduced pain, and improved functionality after 6 months of wear. The lower adduction moment associated with wearing this shoe may slow the rate of progression of osteoarthritis after long‐term use. © 2010 Orthopaedic Research Society.

Scaffold‐free tissue‐engineered cartilage implants for laryngotracheal reconstruction
Authors: Gilpin David A. , Weidenbecher Mark S. , Dennis James E.
Published: January 2010

Objectives/Hypothesis:

Donor site morbidity, including pneumothorax, can be a considerable problem when harvesting cartilage grafts for laryngotracheal reconstruction (LTR). Tissue engineered cartilage may offer a solution to this problem. This study investigated the feasibility of using autologous chondrocytes to tissue‐engineer scaffold‐free cartilage grafts for LTR in rabbits to avoid degradation that often arises from an inflammatory reaction to scaffold carrier matrix.

Study Design:

Animal study.

Methods:

Auricular cartilage was harvested from seven New Zealand white rabbits, the chondrocytes expanded and loaded onto a custom‐made bioreactor for 7 to 8 weeks to fabricate autologous scaffold‐free cartilage sheets. The sheets were cut to size and used for LTR, and the rabbits were sacrificed 4, 8, and 12 weeks after the LTR and prepared for histology.

Results:

None of the seven rabbits showed signs of respiratory distress. A smooth, noninflammatory scar was visible intraluminally; the remainder of the tracheal lumen was unremarkable. Histologically, the grafts showed no signs of degradation or inflammatory reaction, were covered with mucosal epithelium, but did show signs of mechanical failure at the implantation site.

Conclusions:

These results show that autologous chondrocytes can be used to fabricate an implantable sheet of cartilage that retains a cartilage phenotype, becomes integrated, and does not produce a significant inflammatory reaction. These findings suggest that with the design of stronger implants, these implants can be successfully used as a graft for LTR. Laryngoscope, 2010
Ambulatory sinus and nasal surgery in the United States: Demographics and perioperative outcomes
Authors: Bhattacharyya Neil
Published: January 2010

Objectives/Hypothesis:

Determine the prevalence of ambulatory sinonasal surgical procedures and perioperative outcomes in the United States.

Methods:

The National Survey of Ambulatory Surgery 2006 release was examined, extracting all cases of nasal or sinus surgery. Sinonasal surgical procedures were grouped according to septoplasty and/or turbinate surgery, sinus surgery, facial plastic surgery, and other procedures. Overall and group population‐based sinonasal procedure prevalences were estimated from the sample. Frequency of general anesthesia, discharge status, and unexpected emergency room visit estimates were obtained. Perioperative complication rates for cardiac arrest, malignant hyperthermia, postoperative emesis, and blood transfusion were determined as well.

Results:

Overall, an estimated 600,000 patients underwent ambulatory sinonasal procedures in 2006 with a mean age of 40.4 years and 53.7% male predominance. On a per patient basis, there were 260,000 septoplasties, 257,000 sinus cases, 134,000 plastics cases, and 103,000 other cases. Facial plastics procedures were less likely to use general anesthesia (72.8%) than the overall cohort (90.7%, P < .001). The vast majority of patients were discharged to home with an unexpected admission rate of 2.65%. Among the sample, there were no cases of cardiac arrest, malignant hyperthermia, or blood transfusion. The postprocedure emesis rate was 1.3%, not significantly different among procedure groups (P = .692). Only 0.1% of patients visited the emergency room postprocedure.

Conclusions:

Approximately 600,000 ambulatory sinonasal cases are performed each year in the United States. Complication rates and unexpected postprocedure mission rates are quite low indicating the safety and effectiveness of the ambulatory setting for sinonasal surgery. Laryngoscope, 2010
Parotidotomy approach for a midcheek mass: A new surgical strategy
Authors: Jung Young Ho , Hah J. Hun , Sung Myung‐Whun , Kim Kwang Hyun
Published: January 2010

Objectives/Hypothesis:

To report the feasibility and the results of a new surgical strategy for midcheek masses we called the parotidotomy approach.

Study Design:

Retrospective consecutive case series.

Methods:

Characteristics, surgical outcome, and cosmetic result of cases managed using the parotidotomy approach were collected by retrospectively reviewing medical records. The standard superficial parotidectomy approach was modified to dissect facial nerve branches selectively to obtain a symmetric facial contour. The parotid gland was fully bisected along the course of the zygomatic and buccal branches of the facial nerve to provide access to the midcheek mass. The bisected parotid gland was repositioned after mass excision.

Results:

Seven patients (3 males and 4 females) were included in this study. The parotidotomy approach was accomplished in two cases with a malignant tumor (one acinic cell carcinoma, one low‐grade mucoepidermoid carcinoma), four with a benign tumor (two pleomorphic adenoma, one basal cell adenoma, one facial nerve schwannoma), and in one case with a chronic inflammatory lesion (chronic sialadenitis). In no case was facial nerve paralysis or Frey's syndrome noticed after this approach. For the two malignant tumors, there was no evidence of recurrence or metastasis at 2‐year and 2.5‐year follow‐ups. Six of the seven patients were fully satisfied with the cosmetic results of surgery. The remaining patient had a mild sunken deformity of the midcheek where the mass had been located.

Conclusions:

To manage midcheek masses we modified the standard parotidectomy approach. This new surgical strategy, which we named the parotidotomy approach, provides surgically safe and cosmetically excellent results for midcheek masses. Laryngoscope, 2010
Blends of Oppositely Charged PEG–PPG–PEG Copolymers Displaying Improved Physical Thermogelling Properties
Authors: Lee Seung Yong , Lee Yuhan , Chae Su Young , Park Tae Gwan , Ahn Cheol‐Hee
Published: January 2010

Oppositely charged F127 copolymers with a substitution ratio >95% were synthesized by end‐group modification. Single succinic anhydride end‐capped F127 (F127‐SA) or triple (F127‐Tris‐SA) carboxylic acid groups were introduced to the distal ends via esterification. F127 was also end‐capped with two types of amines, triethylenetetramine (F127‐TETA) and ethylene diamine (F127‐EDA). Oppositely charged copolymers were solution‐blended to produce co‐micellized nanostructures at the optimized blend compositions, as determined by ξ‐potential measurement and the composition dependence of the sol–gel phase‐transition temperature. F127 exhibited the approximate storage modulus of 40 000 Pa, while the 1:1 w/w F127‐SA/F127‐TETA and 1:3 w/w F127‐Tris‐SA/F127‐EDA blend displayed a modulus of 90 000 and 170 000 Pa, respectively. Hydrogels from negatively charged F127‐SA or positively charged F127‐TETA homopolymer showed the lower storage modulus. The rheological properties of the thermogelling polymers were enhanced by simple modification of the distal ends of F127 copolymers as well as by the additional ionic interactions between oppositely charged micelles.

Swelling and Viscoelastic Characterisation of pH‐Responsive Chitosan Hydrogels for Targeted Drug Delivery
Authors: Jahren Susannah L. , Butler Michael F. , Adams Sarah , Cameron Ruth E.
Published: January 2010

Chitosan hydrogels have been investigated as potential vehicles for targeted drug delivery. The gels were permanently crosslinked with conventional crosslinking agent, glutaraldehyde and the naturally occurring non‐toxic crosslinking agent genipin in both the monomer and polymerised states. The swelling behaviour of all the gels was highly pH dependent. The gels with the lowest crosslink density not only had an increased rate of diffusion but also an increased total release. It is shown that by altering the type and degree of crosslinking in a chitosan hydrogel it is possible to change the swelling and elastic characteristics of the material, which could be of potential interest as an environment responsive drug delivery matrix.
