ABSTRACT

Introduction
Dentinal hypersensitivity can be treated by dentinal tubule occlusion which prevents any stimuli from causing dentinal fluid movement. This in vitro study aims to compare the dentinal tubule occluding capability of four chemical compounds, a bonding agent, a compound of fluoride and hydroxyapatite, potassium oxalate gel and sodium fluoride varnish.

Materials and methods
Forty dentin samples were divided into four groups of 10 samples each. Group A (treated with Clearfil SE Bond), Group B (treated with Remin Pro), Group C (treated with Potassium Oxalate, Vi-sense,) and Group D (treated with Pro Fluoride varnish). The samples were treated with ethylene diamine tetraacetic acid (EDTA) gel prior to application of desensitizing agents to remove the smear layer and open the dentinal tubule orifice. Following the desensitizing treatment the specimens were washed and dehydrated using graded series of ethanol treatments (25, 50, 75, 90 and 100%). After each treatment tubule occlusion was analyzed by scanning electron microscope.

Results
Qualitative and quantitative analysis demonstrated potassium oxalate gel to cause maximum tubule occlusion followed by Remin Pro > Sodium fluoride varnish > Clearfil SE Bond.

Conclusion
Life expectancy is increasing and patients are retaining their natural teeth for a longer time due to effective treatment strategies. The results showed the potential use of these products as an effective means of tubule occlusion.

Necrotizing Fasciitis of Face in Odontogenic Infection: A Rare Clinical Entity
Authors: Vivek GK , Singh Ranjith , Veena GC , Arya Prappanna 
Published: October 2012

ABSTRACT
Necrotizing fasciitis is a progressive, life-threatening, bacterial infection of the skin, the subcutaneous tissue and the underlying fascia, in most cases caused by β-hemolytic group A Streptococcus. Only early diagnosis and aggressive therapy including broad spectrum antibiotics and surgical intervention can avoid systemic toxicity with a high mortality rate. This disease is commonly known to occur in the lower extremities and trunk, and only rarely in the head and neck region, the face being rarest finding. When located in the face necrotizing fasciitis is associated with severe cosmetic and functional complication due to the invasive nature, infection and often due to the necessary surgical treatment. In the following article, we present the successful diagnosis and management of an isolated facial necrotizing fasciitis as a consequence of odontogenic infection.

ABSTRACT
Anophthalmia (The loss an eye) not only impairs patient's vision but also create a noticeable deformity on facial appearance and esthetics. The condition is a psychological distress for the patient interrupting his routine work. 'sarvendriyanam nayanam pradhanum’ states vision to be the supreme among all the senses. A prosthodontist as an integral member of the craniofacial rehabilitation team can help raise the spirits and ease the mind of the affected. Among various approaches, customized ocular prosthesis achieves better comfort and function between prosthesis and orbital tissues. This is a case report of a female patient of age 22 years had lost her eye as a child due to trauma and the above mentioned prosthesis was planned and fabricated to enhance appearance and boost her confidence. Getting eyesight back is not always possible, but maxillofacial prosthetics can help to reduce the pain of psychological embarrassment. Artistic skills are needed in providing a natural look to the prosthesis; this technique may help in a naturally appearing prosthesis with lesser artistic skills.

Effectiveness of mission statements in organizations – A review
Authors: Braun Susanne , Wesche Jenny S , Frey Dieter , Weisweiler Silke , Peus Claudia 
Published: October 2012

AbstractEven though mission statements are standard tools in organizations, their effectiveness is subject to substantial skepticism. This review integrates hitherto published research based on a broad range of objective and subjective effectiveness criteria above and beyond financial performance in for-profit as well as not-for-profit organizations. We conclude that the distal outcome effectiveness of mission statements depends on the following antecedents and intermediate outcomes: (1) the rationale underlying their development; (2) the process of their development and implementation; (3) their content and form; and (4) individual attitudes toward the mission statement. We thereby clarify preconditions of mission statement effectiveness in organizations, and reveal shortcomings in current research.
Are boards on board? A model of corporate board influence on sustainability performance
Authors: Galbreath Jeremy 
Published: October 2012

AbstractExisting research on a board-of-director–sustainability performance relationship have largely examined inside directors, outside directors, and gender diversity – yet empirical results have yet to offer any definitive answers. I posit that this previous research lacks a thorough examination of the role of boards and the means and mechanisms by which they influence performance. Drawing on the board capital perspective and the role of boards, this paper develops a model that highlights the influence of board capital on the future sustainability performance of firms. The model takes into account specific types of human and social capital of outside directors which have previously been unexamined. Beyond the board capital perspective, an argument is put forth that values are largely neglected in the examination of boards of directors, but are necessary in the study of sustainability because of its normative implications. I therefore account for thevalue attunementconcept as a moderating variable in the model. The paper draws on corporate governance and business ethics' literature to generate propositions and offer original insight into the drivers of sustainability performance in organizations.
The impact of different forms of IPO firm legitimacy on the choice of alliance governance structure
Authors: Coombs Joseph E , Bierly Paul E , Gallagher Scott 
Published: October 2012

AbstractWe analyze the effects of four different types of firm legitimacy – managerial, technological, local community legitimacy and business press endorsement – on the choice of alliance governance structure in partnerships with newly public biotechnology firms. We expand current research to differentiate between non-equity, minority equity and joint venture alliance structures. We find that initial public offering of stock (IPO) firms with higher levels of managerial legitimacy and local community legitimacy are more likely to enter into joint ventures than minority equity alliances and non-equity alliances. IPO firms with higher technological legitimacy and business press endorsement are more likely to use a less hierarchical governance structure.

Authors: Filho Francisco de Souza Amorim , Neto José Caporrino , Neto Paulo Saraceni , Melo José Elson Santiago de , Moraes Bruno Teixeira de 
Published: October 2012

Introduction: Leishmaniasis is classified into three clinical presentations: visceral, coetaneous and mucocutaneous. The latter is usually secondary to hematogenous spread after months or years of skin infection and can manifest as infiltrative lesions, ulcerated or vegetating in nose, pharynx, larynx and mouth, associated or not with ganglionics infarction. Laryngeal involvement is part of the differential diagnosis of lesions in this topography as nonspecific chronic laryngitis, granulomatosis and even tumors of the upper aerodigestive tract presenting atypical evolution. Sometimes it is difficult for the correct diagnosis of Leishmaniasis, with description of cases in the literature were conducted improperly.
Objective: The objective of this study is to report a case of laryngeal Leishmaniasis addressing the difficulty of diagnosis, complications and treatment applied.
Case Report: A patient with pain throat, dysphagia, odynophagia, dysphonia and weight loss, with no improvement with symptomatic medication. At telelaringoscopy, infiltrative lesion showed nodular supraglottis. He underwent a tracheotomy for airway obstruction and biopsy with immunohistochemical study for a definitive diagnosis of laryngeal Leishmaniasis. The patient was referred to the infectious diseases that initiated treatment with N-methylglucamine antimoniate with satisfactory response to therapy.
Final Comments: Faced with a clinical suspicion of granulomatous diseases, it is essential to follow protocol laboratory evaluation associated with histological injury, to get a precise definition etiological without prolonging the time of diagnosis. Medical treatment for mucosal Leishmaniasis, recommended by the World Health Organization, was adequate in the case of laryngeal disorders, with complete resolution of symptoms.

Sliding mode control of singularly perturbed Markovian jump delayed systems with nonlinearity
Authors: Wang Yueying , Zhou Pingfang , Wang Quanbao , Duan Dengping 
Published: October 2012

SUMMARYThis paper is concerned with sliding mode control (SMC) of a class of time‐delay nonlinear singularly perturbed Markovian jump systems. Firstly, a switching surface function is designed, and a delay‐dependent condition is derived in terms of ϵ‐independent linear matrix inequality, which guarantees that the resulting sliding mode dynamics is mean‐square exponentially stable. Then an algorithm is given to estimate the stability bound. Moreover, an adaptive SMC law is synthesized to drive the system trajectories onto the designed switching surface in a finite time. Finally, a numerical example is presented to show the effectiveness of proposed method. Copyright © 2012 John Wiley & Sons, Ltd.
Reinforcement of Shear Thinning Protein Hydrogels by Responsive Block Copolymer Self‐Assembly
Authors: Glassman Matthew J. , Chan Jacqueline , Olsen Bradley D. 
Published: October 2012

AbstractShear thinning hydrogels are promising materials that exhibit rapid self‐healing following the cessation of shear, making them attractive for applications including injectable biomaterials. Here, self‐assembly is demonstrated as a strategy to introduce a reinforcing network within shear thinning artificially engineered protein gels, enabling a responsive transition from an injectable state at low temperatures with a low yield stress to a stiffened state at physiological temperatures with resistance to shear thinning, higher toughness, and reduced erosion rates and creep compliance. Protein‐polymer triblock copolymers capable of the responsive self‐assembly of two orthogonal networks are synthesized. Midblock association forms a shear‐thinning network, while endblock aggregation at elevated temperatures introduces a second, independent physical network into the protein hydrogel. These reversible crosslinks introduce extremely long relaxation times and lead to a five‐fold increase in the elastic modulus, significantly larger than is expected from transient network theory. Thermoresponsive reinforcement reduces the high temperature creep compliance by over four orders of magnitude, decreases the erosion rate by at least a factor of five, and increases the yield stress by up to a factor of seven. Combined with the demonstrated potential of shear thinning artificial protein hydrogels for various uses, this reinforcement mechanism broadens the range of applications that can be addressed with shear‐thinning physical gels.
Heritable disorders in the metabolism of the dolichols: A bridge from sterol biosynthesis to molecular glycosylation
Authors: Wolfe Lynne A. , Morava Eva , He Miao , Vockley Jerry , Gibson K. Michael 
Published: October 2012

AbstractDolichols, polyisoprene alcohols derived from the mevalonate pathway of cholesterol synthesis, serve as carriers of glycan precursors for the formation of oligosaccharides important in protein glycosylation. Seven autosomal‐recessively inherited disorders in the metabolism (synthesis, utilization, recycling) of the dolichols have recently been described, and all are associated with decreased lipid‐linked oligosaccharides leading to underglycosylated proteins or lipids which facilitate their detection in the diagnostic laboratory. Multisystem pathology encompasses developmental delays and eye, heart, skin and muscle abnormalities; outcomes range from death in infancy to mild, late‐onset disease. © 2012 Wiley Periodicals, Inc.

AbstractA simple method for the preparation of magnetic nanocomposites consisting of cobalt ferrite (CF; CoFe2O4) nanoparticles, polybenzoxazine (PB), linear low‐density polyethylene (LLDPE), and linear low‐density polyethylene‐g‐maleic anhydride (LgM) is described. The composites were prepared by the formation of benzoxazine (BA)–CF nanopowders followed by melt blending with LLDPE and the thermal curing of BA. The composites were characterized by X‐ray diffraction, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy, universal testing machine measurement, and vibrating sample magnetometry. The composites consisting of LLDPE, PB, and LgM (47.5L–47.5PB–5LgM) exhibited a higher tensile strength (23.82 MPa) than pure LLDPE and a greater elongation at break (6.11%) than pure PB. The tensile strength of the composites decreased from 19.92 to 18.55 MPa with increasing CF loading (from 14.25 to 33.25 wt %). The saturation magnetization of the composites containing 33.25 wt % CF was 18.28 emu/g, and it decreased with decreasing amount of CF in the composite. The composite films exhibited mechanical flexibility and magnetic properties. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Recombinant rabbit single‐chain antibodies bind to the catalytic and C‐terminal domains of HIV‐1 integrase protein and strongly inhibit HIV‐1 replication

Published: October 2012

AbstractThe human immunodeficiency virus type 1 (HIV‐1) integrase (IN) protein plays an important role during the early stages of the retroviral life cycle and therefore is an attractive target for therapeutic intervention. We immunized rabbits with HIV‐1 IN protein and developed a combinatorial single‐chain variable fragment (scFv) library against IN. Five different scFv antibodies with high binding activity and specificity for IN were identified. These scFvs recognize the catalytic and C‐terminal domains of IN and block the strand‐transfer process. Cells expressing anti‐IN–scFvs were highly resistant to HIV‐1 replication due to an inhibition of the integration process itself. These results provide proof‐of‐concept that rabbit anti‐IN–scFv intrabodies can be designed to block the early stages of HIV‐1 replication without causing cellular toxicity. Therefore, these anti‐IN–scFvs may be useful agents for “intracellular immunization”‐based gene therapy strategies. Furthermore, because of their epitope binding characteristics, these scFvs can be used also as new tools to study the structure and function of HIV‐1 IN protein.
Large enhancement of oscillating chemiluminescence with [Ru(bpy)3]2+‐catalyzed Belousov–Zhabotinsky reaction in the presence of tri‐n‐propylamine
Authors: Lan Xiaolan , Zheng Baozhan , Zhao Yan , Yuan Hongyan , Du Juan , Xiao Dan 
Published: October 2012

ABSTRACTOscillating chemiluminescence enhanced by the addition of tri‐n‐propylamine (TPrA) to the typical Belousov–Zhabotinsky (BZ) reaction system catalyzed by ruthenium(II)tris(2.2'‐bipyridine)(Ru(bpy)32+) was investigated using a luminometry method. The [Ru(bpy)3]2+/TPrA system was first used as the catalyst for a BZ oscillator in a closed system, which exhibited a shorter induction period, higher amplitude and much more stable chemiluminescence (CL) oscillation. The effects of various concentrations of TPrA, oxygen and nitrogen flow rate on the oscillating behavior of this system were examined. In addition, the CL intensity of the [Ru(bpy)3]2+/TPrA–BZ system was found to be inhibited by phenol, thus providing a way for use of the BZ system in the determination of phenolic compounds. Moreover, the possible mechanism of the oscillating CL reaction catalyzed by [Ru(bpy)3]2+/TPrA and the inhibition effects of oxygen and phenol on this oscillating CL system were considered.
