Return-to-Play Recommendations After Cervical, Thoracic, and Lumbar Spine Injuries
Authors: Huang Philip , Anissipour Alireza , McGee William , Lemak Lawrence 
Published: October 2015

Context: Currently, there is a national focus on establishing and disseminating standardized guidelines for return to play for athletes at all levels of competition. As more data become available, protocols and guidelines are being refined and implemented to assist physicians, coaches, trainers, players, and parents in making decisions about return to play. To date, no standardized criteria for returning to play exist for injuries to the spine. Evidence Acquisition: Electronic databases including PubMed and MEDLINE and professional orthopaedic, neurosurgical, and spine organizational websites were reviewed between 1980 and 2015. Study Design: Clinical review. Level of Evidence: Level 4. Results: Although clinical guidelines have been published for return to play after spine injury, they are almost exclusively derived from expert opinion and clinical experience rather than from well-designed studies. Furthermore, recommendations differ and vary depending on anatomic location, type of sport, and surgery performed. Conclusion: Despite a lack of consensus and specific recommendations, there is universal agreement that athletes should be pain free, completely neurologically intact, and have full strength and range of motion before returning to play after spinal injury.

AbstractWe prove a convergence theorem of the Mann iteration scheme for a uniformlyL-Lipschitzian asymptotically demicontractive mapping in a$\operatorname{CAT}(\kappa)$CAT(κ)space with$\kappa>0$κ>0. We also obtain a convergence theorem of the Ishikawa iteration scheme for a uniformlyL-Lipschitzian asymptotically hemicontractive mapping. Our results provide a complete solution to an open problem raised by Kim (Abstr. Appl. Anal. 2013:381715, 2013).

AbstractThe 2 gut hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) are well known to be coexpressed, costored, and released together to coact in the control of key metabolic target organs. However, recently, it became clear that several other gut hormones can be coexpressed in the intestinal-specific lineage of enteroendocrine cells. Here, we focus on the anatomical and functional consequences of the coexpression of neurotensin with GLP-1 and PYY in the distal small intestine. Fluorescence-activated cell sorting analysis, laser capture, and triple staining demonstrated that GLP-1 cells in the crypts become increasingly multihormonal, ie, coexpressing PYY and neurotensin as they move up the villus. Proglucagon promoter and pertussis toxin receptor-driven cell ablation and reappearance studies indicated that although all the cells die, the GLP-1 cells reappear more quickly than PYY- and neurotensin-positive cells. High-resolution confocal fluorescence microscopy demonstrated that neurotensin is stored in secretory granules distinct from GLP-1 and PYY storing granules. Nevertheless, the 3 peptides were cosecreted from both perfused small intestines and colonic crypt cultures in response to a series of metabolite, neuropeptide, and hormonal stimuli. Importantly, neurotensin acts synergistically, ie, more than additively together with GLP-1 and PYY to decrease palatable food intake and inhibit gastric emptying, but affects glucose homeostasis in a more complex manner. Thus, neurotensin is a major gut hormone deeply integrated with GLP-1 and PYY, which should be taken into account when exploiting the enteroendocrine regulation of metabolism pharmacologically.
Cell adhesion strength from cortical tension – an integration of concepts
Authors: Winklbauer Rudolf 
Published: October 2015

ABSTRACT
Morphogenetic mechanisms such as cell movement or tissue separation depend on cell attachment and detachment processes, which involve adhesion receptors as well as the cortical cytoskeleton. The interplay between the two components is of stunning complexity. Most strikingly, the binding energy of adhesion molecules is usually too small for substantial cell–cell attachment, pointing to a main deficit in our present understanding of adhesion. In this Opinion article, I integrate recent findings and conceptual advances in the field into a coherent framework for cell adhesion. I argue that active cortical tension is best viewed as an integral part of adhesion, and propose on this basis a non-arbitrary measure of adhesion strength – the tissue surface tension of cell aggregates. This concept of adhesion integrates heterogeneous molecular inputs into a single mechanical property and simplifies the analysis of attachment–detachment processes. It draws attention to the enormous variation of adhesion strengths among tissues, whose origin and function is little understood.

The Marginal Cost of Risk, Risk Measures, and Capital Allocation
Authors: Bauer Daniel , Zanjani George 
Published: October 2015

Financial institutions use risk measures to calculate the marginal capital cost when expanding the exposure to a certain risk within their portfolio. We reverse this approach by calculating the marginal cost based on economic fundamentals for a profit-maximizing firm and then by identifying the risk measure delivering the correct marginal cost. The resulting measure depends on context. Whereas familiar measures can be recovered in some circumstances, other circumstances yield unfamiliar forms. In all cases, the risk preferences of the institution’s claimants determine how the correct risk measure must weight various default states. Our results demonstrate that risk measures used for pricing and performance measurement should be chosen based on economic fundamentals and may not necessarily adhere to the mathematical properties typically imposed in the literature.

Using patient feedback to improve a colorectal enhanced recovery service
Authors: Burch Jennie 
Published: October 2015

Introduction The purpose of this study was to review patients' experiences of a colorectal enhanced recovery pathway to enable service evaluation and improvement. Method A short questionnaire was given to patients in the surgical follow-up clinic. Questions covered enhanced recovery topics, from preoperative information through to discharge, and patients' needs at home. Results Most patients were satisfied with their care, but there were areas that required improvement, such as the food served at the hospital and the information provided in the enhanced recovery booklet. Conclusion Patient's perceptions of care are good, but there are areas still in need of improvement. The findings of this review support what is already known about patients' experiences of enhanced recovery, including high patient satisfaction.
Ambient Ionization Mass Spectrometry for Point-of-Care Diagnostics and Other Clinical Measurements

Published: October 2015

AbstractBACKGROUNDOne driving motivation in the development of point-of-care (POC) diagnostics is to conveniently and immediately provide information upon which healthcare decisions can be based, while the patient is on site. Ambient ionization mass spectrometry (MS) allows direct chemical analysis of unmodified and complex biological samples. This suite of ionization techniques was introduced a decade ago and now includes a number of techniques, all seeking to minimize or eliminate sample preparation. Such approaches provide new opportunities for POC diagnostics and rapid measurements of exogenous and endogenous molecules (e.g., drugs, proteins, hormones) in small volumes of biological samples, especially when coupled with miniature mass spectrometers.CONTENTAmbient MS-based techniques are applied in diverse fields such as forensics, pharmaceutical development, reaction monitoring, and food analysis. Clinical applications of ambient MS are at an early stage but show promise for POC diagnostics. This review provides a brief overview of various ambient ionization techniques providing background, examples of applications, and the current state of translation to clinical practice. The primary focus is on paper spray (PS) ionization, which allows quantification of analytes in complex biofluids. Current developments in the miniaturization of mass spectrometers are discussed.SUMMARYAmbient ionization MS is an emerging technology in analytical and clinical chemistry. With appropriate MS instrumentation and user-friendly interfaces for automated analysis, ambient ionization techniques can provide quantitative POC measurements. Most significantly, the implementation of PS could improve the quality and lower the cost of POC testing in a variety of clinical settings.
The completion problem for equivariant K-theory

Published: October 2015

Abstract
In this paper, we study the Atiyah–Segal completion problem for
the equivariant algebraic K-theory.
We show that this completion problem has a positive solution for the action
of connected groups on smooth projective schemes. In contrast, we show that
this problem has a negative solution for non-projective smooth schemes, even
if the action has only finite stabilizers.
Non-abelian analogs of lattice rounding
Authors: Begelfor Evgeni , Miller Stephen D. , Venkatesan Ramarathnam 
Published: October 2015

AbstractLattice rounding in Euclidean space can be viewed as finding the nearest point in the orbit of an action by a discrete group, relative to the norm inherited from the ambient space. Using this point of view, we initiate the study of non-abelian analogs of lattice rounding involving matrix groups. In one direction, we consider an algorithm for solving a normed word problem when the inputs are random products over a basis set, and give theoretical justification for its success. In another direction, we prove a general inapproximability result which essentially rules out
Mathematical Modeling of Biodiesel Production under Intense Agitation
Authors: Roosta Aliakbar , Javanmardi Jafar , Behineh Elham Sadat 
Published: October 2015

Abstract
In this study, a new approach is proposed to investigate the kinetics of sunflower oil and rapeseed oil transesterification in the presence of potassium hydroxide. Transesterification is a heterogeneous process which affected by a number of parameters, that are not readily available in the literature, such as mass transfer coefficients, partition coefficients, and specific surface area of the dispersed phase. However, under intense agitation condition, mass transfer restrictions may be neglected, and the two phases are supposed to remain in thermodynamic equilibrium, during the process. Therefore, a model was developed independent of the mass transfer coefficient and specific surface area, which is reliable for the intense agitation condition. According to the results, the model is valid at least for mixing rates over 500 rpm. The results of the model were used to study the effects of temperature, methanol-to-oil ratio, and catalyst concentration on the biodiesel conversion. Biodiesel production rate increases with increasing temperature, although rapeseed oil transesterification is more temperature dependent. The results show that the maximum amount of catalyst concentration is less than 1% (by weight); however, the optimum value depends on the operating temperature. The optimum value of the methanol-to-oil-ratio decreases with increasing temperature. Thus, at higher temperatures, less amount of methanol and catalyst are required, which leads to easier purification of biodiesel.

Islamic Credit Cards and Consumptive Behaviour of Society. The credit card as one means of payment utilising cards, is a payment system that is growing rapidly, brought about by the security and risk of carrying cash in large amounts, efficiency, speed and ease of transaction that is offered. Islamic banks are glancing consumer funding products as one of the products services to be offered. There is a very important limitation that must be realized for Islamic banks, namely the provisions of the shari’a principles regarding the provision of credit card and influence on consumer behaviour society, particularly the Muslim community. It is not impossible for the existence of Islamic credit cards that are presented for the ease of transacting to become a card for the ease of indebtedness and cause a consumptive/wasteful attitude that is definitely forbidden in Islamic economic concept.DOI: 10.15408/ajis.v14i2.1287

<p>This study explored a contemporary counternarrative of Drama Club, a transformative culture of teaching and learning for disenfranchised Black youth who had been systematically funneled out of classrooms and into the school-to-prison pipeline. Auto/biographical and auto/ethnographical data were collected and assembled as a metaphor of the teachers’ and students’ experiences in Drama Club and their understanding of the teaching and learning process and of themselves within it. The collective story of Drama Club was analyzed through the lens of culturally responsive pedagogy theory and critical race theory in education. Implications for future research and teacher education that set out to impact disenfranchised students are included.</p>
Disciplinary identities and crossing boundaries: The academization of speleology in the first half of the twentieth century
Authors: Mattes Johannes 
Published: October 2015

This paper examines the development and legitimization of the study of caves as an academic scientific discipline from the end of the 19th century to World War II. It discusses the function of history and related methodological and epistemological practices used to define and legitimize speleology as an academic discipline. It also discusses the political and social context involved in this process of academization. In this context, special attention is paid to the formation of disciplinary identities and transdisciplinary cooperation. The role of individuality and community in science goes hand-in-hand with the construction of combined memory, which gives an identity to each researcher and attributes significance and legitimization to his or her activity.
At the turn of the 20th century, the term ‘speleology’ was introduced for this newly developed interdisciplinary study of caves. Speleology was regarded as a ‘group’ or ‘synthetic science’, linking different branches of the humanities and natural sciences, such as geology, geography, mineralogy, hydrology, meteorology, paleontology, zoology, botany, anthropology, archeology, prehistory, and art history. The claim that speleology was a new academic scientific discipline also involved an enforced differentiation between cave study as a science and exploration for leisure purposes. This led to the foundation of the first chair and university institute of speleology in Vienna in 1929.
Reducing Dental Plaque and Gingivitis With 0.6% Cortex Ilicis Rotundae Toothpaste: A Randomized, Double‐Masked Clinical Trial
Authors: Liu Hongchun , Yin Wei 
Published: October 2015

Background: Cortex Ilicis Rotundae has antioxidant and anti‐inflammatory properties. Few studies have evaluated the effects of toothpastes containing Cortex Ilicis Rotundae. This study evaluates the antiplaque and antigingivitis effects of a test toothpaste containing 0.6% Cortex Ilicis Rotundae extract in a calcium carbonate base compared with a control toothpaste without any active ingredient.Methods: One hundred adults with a mean plaque index (PI) ≥1.5 and a mean gingival index (GI) ≥1.0 were enrolled in this randomized, double‐masked, placebo‐controlled clinical trial. They were assigned randomly to use a test toothpaste or a control toothpaste. At baseline, 6 weeks, and 12 weeks, they received examinations of oral hard and soft tissues, using Löe‐Silness GI for gingivitis and the Turesky modification of the Quigley‐Hein PI for PI. Adverse events were monitored.Results: When the study was completed, the test group reported lower mean GI than the control group (1.13 ± 0.22 versus 1.30 ± 0.23; P = 0.001) and lower mean PI than the control group (2.53 ± 0.5 versus 2.93 ± 0.44; P <0.001). Compared to the baseline, the test group had reductions in GI and PI of 14.39% and 17.86%, respectively (both P <0.001); the control group had reductions in GI and PI of 3.7% and 3.93%, respectively (both P <0.001). No adverse events were reported during the course of the study.Conclusion: The toothpaste containing 0.6% Cortex Ilicis Rotundae was effective in reducing dental plaque and gingivitis after 12 weeks of use compared with a negative control toothpaste.
