Patterns of Metatarsal Explosion After New Modern Minimally Invasive Bunion Surgery. A Retrospective Review and Case Series of 16 Feet.
Authors: Blitz Neal M. , Wong David T. , Baskin Eric S. 
Published: March 2024

Introduction First metatarsal explosion is a new serious postoperative complication that occurs with new minimally invasive bunion surgery and has yet to be reported or analyzed. This retrospective study investigated associated factors. We present a classification system (3 Types), mechanism and treatment paradigm. Methods A case review was performed between January 2018 to May 2022 and we identified 16 feet (15 patients) with metatarsal explosion. We evaluated age, sex, BMI, laterality, preoperative intermetatarsal angle, medical comorbidities, screw placement, number of screws and patterns of fracture. Results The median age was 61.6 years and 80% of patients were females. Forty percent were obese. Forty percent had thyroid disorders. One patient had bilateral explosion. The metatarsal explosion distributions were Type I 50%, Type II 31% and Type III 19%. Twelve feet (75%) of metatarsal explosions occurred in a region we coin the Cortical Purchase Zone (CPZ). Forty three percent of metatarsal explosions had screws starting distal/dorsal in the metatarsal base, a region we coin the Cancellous Anchor Zone (CAZ). Metatarsal explosion distribution was not significantly associated with age, gender, laterality, preoperative intermetatarsal angle, screw placement and all medical comorbidities. Worse metatarsal explosions were more likely with two metatarsal screws (p < 0.05). Treatment was non-surgical for 12 feet (75%) and open reduction internal fixation for 4 feet (25%). Conclusion Metatarsal explosion has three distinct types and we present a new classification system. Two screw fixation was more likely to have a metatarsal explosion. Etiologic observations suggest screw placement as a contributing cause. Treatment was mainly non-operative and surgery was utilized for unstable displaced explosions.
Réflexion sur la nature et l’usage de la connaissance en nutrition – Un appel à davantage d’éthique
Authors: Vaillancourt Hugues , Geoffrion Marie-Noël 
Published: March 2024

La nutrition se définit comme la science appliquée qui s’intéresse à la relation entre l’alimentation et la santé. Or, l’alimentation est un objet d’intérêt et d’étude pour plusieurs autres disciplines. L’application des connaissances en nutrition demeure cependant essentiellement réfléchie en accordant par défaut une primauté épistémique à la fonction biomédicale de l’alimentation. Les connaissances issues de ces autres disciplines se retrouvent alors généralement dépréciées, voire écartées. L’éthique semble en mesure de fournir un terrain neutre afin de confronter et concilier les différentes perspectives disciplinaires sur l’alimentation. L’approfondissement d’une réflexion éthique propre à la pratique de la nutrition est souhaité afin d’améliorer la pertinence de ses efforts d’application des connaissances. L’article propose quatre principaux thèmes éthiques autour desquels pourrait s’organiser l’analyse des enjeux épistémiques en lien avec la nutrition et l’alimentation. Ces thèmes discutés dans l’article sont : l’identité, la liberté, la justice et la dignité.
« N’aimez pas le monde ni ce qui est dans le monde » (1 Jn 2,15) : la première épître johannique au regard de la crise écologique
Authors: Luna Rodolfo Felices 
Published: March 2024

Dans la foulée des travaux menés par le groupe Earth Bible, cet essai applique les principes de lecture écoresponsable à trois traductions courantes en français de 1 Jn 2,15-17. La terminologie traditionnelle peut choquer les sensibilités des lectrices et lecteurs contemporains, notamment par rapport à la valeur du monde et au temps des vivants. La crise écologique invite à repenser les mots employés pour rendre le texte biblique. Cet essai propose une traduction alternative, qui respecte les idées-forces de l’épître, tout en dissipant les malentendus que l’emploi de vocables tels que « monde » et « éternité » pourrait susciter dans l’esprit d’un lectorat non averti.
Sex differences in strength at the shoulder: a systematic review
Authors: Kritzer Tamar D. , Lang Cameron J. , Holmes Michael W. R. , Cudlip Alan C. 
Published: March 2024

Background
Understanding differential strength capability between sexes is critical in ergonomics and task design. Variations in study designs and outcome measures generates challenges in establishing workplace guidelines for strength requirements to minimize upper extremity risk for workers. The purpose of this systematic review was to collate and summarize sex differences in strength at the shoulder across movement directions and contraction types.

Methods
A total of 3,294 articles were screened from four databases (Embase, Medline, SCOPUS, and Web of Science). Eligibility criteria included observational studies, direct measurement of muscular joint, and healthy adult participants (18–65 years old). Strength outcome measures were normalized to percentages of male outputs to allow comparisons across articles.

Results
A total of 63 studies were included within the final review. Majority of articles observed increased strength in males; the gap between male–female strength was greater in flexion and internal/external rotation, with females generating ~30% of male strength; scaption strength ratios were most consistent of the movement groups, with females generating 55–62% of male strength.

Conclusion
Sex strength differences should be considered as an important factor for workplace task design as women are more at risk for occupational-related injuries than men in equivalent strength requirements. Differences in strength were not synonymous across motions; females demonstrated increased disparity relative to male strength in horizontal flexion/extension, forward flexion and internal/external rotation. Some movements had an extremely limited pool of available studies for examination which identified critical research gaps within the literature. Collating and quantifying strength differences is critical for effective workstation design with a range of users to mitigate potential overexertion risk and musculoskeletal injury.
Biomedical Materials
Authors: Lyman Donald J. , Rowland Stephen M. 
Published: March 2007

Abstract
Polymeric materials are used in a variety of corporeal, paracorporeal, and extracorporeal applications; however, their utility would be improved with better biocompatibility. The development of new biomedical polymers requires integrating polymer science and engineering with cellular and molecular biology. Suggested criteria for biocompatible polymer materials are presented. Physiological defense mechanisms elicited in response to implanted biomedical polymers are discussed. Implant design and strategies to achieve biocompatibility are outlined.
Depolymerization
Authors: Sawada Hideo 
Published: March 2007

AbstractThis article provides an overview of depolymerization from a thermodynamic and kinetic perspective. Depolymerization is characterized by the scission of the main chain backbone. Three types of reactions such as random degradation, depolymerization and weak‐link degradation may occur separately or in conjunction with each other. The kinetic treatment of depolymerization processes has been described in the case of random degradation and chain depolymerization. Depolymerization is characterized as their thermodynamic and energetic features such as heat, entropy, free energy for polymerization, bond‐dissociation energy, and activation energy. Current applications of depolymerization are found in various fields such as biological recycling (biorecycling), chemical recycling, agricultural uses in natural environment, and medical uses.
Using Molecular Force to Overcome Steric Barriers in a Springlike Molecular Ouroboros**
Authors: Nygaard S. , Liu Y. , Stein P. C. , Flood A. H. , Jeppesen J. O. 
Published: March 2007

AbstractA mechanically interlocked and self‐complexing molecular ouroboros that incorporates the π‐electron‐rich monopyrrolotetrathiafulvalene (MPTTF) unit and the π‐electron‐poor tetracationic macrocycle cyclobis(paraquat‐p‐phenylene) (CBPQT4+) has been synthesized and characterized. The molecular ouroboros constitutes an interesting class of redox‐active interlocked molecules that is structurally similar to the image of the Serpent biting its own tail, whereas, and towards advanced functionality, its mode of action resembles a wound spring. Electrochemical methods and short timescale UV‐vis‐NIR (NIR: near IR) chemical switching experiments verified the reversible oxidation and reduction of the molecular ouroboros akin to the build‐up and release of tension in a spring. Building out from this concept, it was determined by the time evolution of the 1H NMR and UV‐vis‐NIR spectra, however, that the initially interlocked molecular ouroboros is converted into a linear non‐interlocked state by the employment of an appropriate oxidation–reduction cycle. The oxidation‐induced dethreading process occurs when the dicationic MPTTF2+ unit is kept within close proximity to the CBPQT4+ ring by the circular interlocked structure in order to maintain the electrostatic repulsive force between the MPTTF2+ unit and the CBPQT4+ ring for longer periods of time. The resulting high‐energy, and now tightly wound, interlocked conformation overcomes a steric barrier in many minutes, relaxing thermodynamically to form the lowest‐energy linear state in an irreversible process that would otherwise be kinetically improbable without the oxidation.
Atom transfer radical polymerization of butadiene using MoO2Cl2/PPh3 as the catalyst
Authors: Hua Jing , Li Xin , Li Yue‐Sheng , Xu Ling , Li Yan‐Xia 
Published: March 2007

AbstractAtom transfer radical polymerization has been used to successfully synthesize polybutadiene. This was achieved by using MoO2Cl2/triphenyl phosphine as the catalyst and the various organic halide compounds such as methyl‐2‐chloropropionate, CCl4, 1,4‐dichloromethyl benzene, 1‐phenylethyl chloride, and benzyl chloride as initiators. The monomer conversion increased up to 50% with polymerization time. The polydispersity indices of the polymers were as high as above 1.5. However, the polymerizations were controlled and the polydispersity indices of the polymers were less than 1.5 throughout the polymerizationin reverse atom transfer radical polymerization. The chemical structure of the polymer obtained was characterized by 1HNMR and FTIR. The valency states of molybdenum in this reactive system were detected by UV–vis spectra. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 3517–3522, 2007
The Algorithmically Structured Systematic Exploration of Subject's State of Mind. I. Development of a New Interview
Authors: Stoléru Serge , le Mer Marie‐Noëlle 
Published: March 2007

AbstractObjective: To develop an interview method that combined the qualities of unstructured interviews, such as openness to unexpected information, and the qualities of structured interviews, such as adequate psychometric properties. Method: The innovative principle of the Algorithmically Structured Systematic Exploration of Subject's State of Mind (Assess_Mind) is to investigate, not the contents of mental phenomenology, but five mental functions – or “registers” – that mediate the experience of patients. The functioning of these registers – affects, fears, desires, memories, and associations of ideas – is explored using a rigorously defined algorithm for interviewing. Scales have been developed to rate 390 interviews on psychopathological dimensions of interest in a study of patients undergoing in vitro fertilization (IVF) treatment. Results: As shown by vignettes from the various registers, the Assess_Mind provides detailed, comprehensive, and deep information on the five registers it investigates. Conclusion: Although the Assess_Mind uses a structured algorithm for data collection, its usefulness as a clinical research tool is based on the width and depth of its coverage of patients' current mental experience.

Selection power and selection labor for information retrieval
Authors: Warner Julian 
Published: March 2007

AbstractThis study examines the relation between selection power and selection labor for information retrieval (IR). It is the first part of the development of a labor theoretic approach to IR. Existing models for evaluation of IR systems are reviewed and the distinction of operational from experimental systems partly dissolved. The often covert, but powerful, influence from technology on practice and theory is rendered explicit. Selection power is understood as the human ability to make informed choices between objects or representations of objects and is adopted as the primary value for IR. Selection power is conceived as a property of human consciousness, which can be assisted or frustrated by system design. The concept of selection power is further elucidated, and its value supported, by an example of the discrimination enabled by index descriptions, the discovery of analogous concepts in partly independent scholarly and wider public discourses, and its embodiment in the design and use of systems. Selection power is regarded as produced by selection labor, with the nature of that labor changing with different historical conditions and concurrent information technologies. Selection labor can itself be decomposed into description and search labor. Selection labor and its decomposition into description and search labor will be treated in a subsequent article, in a further development of a labor theoretic approach to information retrieval.

Authors: Calloway Nathaniel T. , Choob Michael , Sanz Ana , Sheetz Michael P. , Miller Lawrence W. , Cornish Virginia W. 
Published: March 2007

AbstractThe combined technologies of optical microscopy and selective probes allow for real‐time analysis of protein function in living cells. Synthetic chemistry offers a means to develop specific, protein‐targeted probes that exhibit greater optical and chemical functionality than the widely used fluorescent proteins. Here we describe pharmacokinetically optimized, fluorescent trimethoprim (TMP) analogues that can be used to specifically label recombinant proteins fused to E. coli dihydrofolate reductase (eDHFR) in living, wild‐type mammalian cells. These improved fluorescent tags exhibited high specificity and fast labeling kinetics, and they could be detected at a high signal‐to‐noise ratio by using fluorescence microscopy and fluorescence‐activated cell sorting (FACS). We also show that fluorescent TMP–eDHFR complexes are complements to green fluorescent protein (GFP) for two‐color protein labeling experiments in cells.
Synthesis of Metal–(Pentadentate‐Salen) Complexes: Asymmetric Epoxidation with Aqueous Hydrogen Peroxide and Asymmetric Cyclopropanation (salenH2: N,N′‐bis(salicylidene)ethylene‐1,2‐diamine)
Authors: Shitama Hiroaki , Katsuki Tsutomu 
Published: March 2007

AbstractIt is known that the rates and stereochemical outcomes of epoxidations and cyclopropanations using a metallosalen (salenH2: N,N′‐bis(salicylidene)ethylene‐1,2‐diamine) complex as catalyst are affected by a trans effect of the apical ligand of the complex. By taking into consideration this trans effect, we have synthesized optically active pentadentate salen ligands bearing an imidazole or pyridine derivative as the fifth coordinating group, and have prepared the corresponding manganese(III) and cobalt(II) complexes, in which the fifth ligand is expected to intramolecularly coordinate to the metal center and exert a trans effect. Indeed, high enantioselectivity has been achieved in epoxidations using aqueous hydrogen peroxide as the terminal oxidant and in cyclopropanations with these complexes as catalysts. In general, metallosalen‐catalyzed reactions have been carried out in the presence of an excess of a donor ligand; however, the present reactions do not need the addition of any extra donor ligand.
