Background:

A short-term protocol for evaluation of National Football League (NFL) athletes incurring concussion has yet to be fully defined and framed in the context of the short-term potential team and career longevity, financial risk, and performance.

Purpose:

To compare the short-term career outcomes for NFL players with concussions by analyzing the effect of concussions on (1) franchise release rate, (2) career length, (3) salary, and (4) performance.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

NFL player transaction records and publicly available injury reports from August 2005 to January 2016 were analyzed. All players sustaining documented concussions were evaluated for a change to inactive or DNP (“did not participate”) status. A case-control design compared franchise release rates and remaining NFL career span. Career length was analyzed via survival analysis. Salary and performance differences were analyzed with publicly available contract data and a performance-scoring algorithm based on position/player level.

Results:

Of the 5894 eligible NFL players over the 11-year period, 307 sustained publicly reported concussions resulting in the DNP injury protocol. Analysis of the probability of remaining in the league demonstrated a statistically significantly shorter career length for the concussion group at 3 and 5 years after concussion. The year-over-year change in contract value for the concussion group resulted in a mean overall salary reduction of $300,000 ± $1,300,000 per year (interquartile range, –$723,000 to $450,000 per year). The performance score reduction for all offensive scoring players sustaining concussions was statistically significant.

Conclusion:

This retrospective study demonstrated that NFL players who sustain a concussion face a higher overall franchise release rate and shorter career span. Players who sustained concussions may incur significant salary reductions and perform worse after concussion. Short-term reductions in longevity, performance, and salary after concussion exist and deserve additional consideration.

Asthma during pregnancy is associated with retardation of fetal growth in a sex-specific manner. Lactobacilli microbes influence infant growth. This study aimed to determine whether lactobacilli and other microbes are reduced in the gut of infants born to an asthmatic mother, and whether this differs by the sex of the infant.

Mother-infant pairs (N=1021) from the Canadian Healthy Infant Longitudinal Development full-term cohort were studied. The abundance of infant faecal microbiota at 3–4 months, profiled by gene sequencing, was compared between both women with and without asthma treatment during pregnancy. Infant sex, maternal ethnicity, pre-pregnancy overweight and atopy status, birth mode, breastfeeding status and intrapartum antibiotic treatment were tested as covariates.

Independent of birth mode and other covariates, male, Caucasian infants born to women with prenatal asthma harboured fewer lactobacilli in the gut at 3–4 months of age. If asthmatic mothers had pre-pregnancy overweight, the abundance ofLactobacillusin males was further reduced in the infant gut, whereas the microbiota of female infants was enriched withBacteroidaceae. Similar differences in infant gut microbial composition according to maternal prenatal asthma status were also more evident among women with food or environmental allergies.

Gut lactobacilli were less abundant in male infants, butBacteroidaceaewere more abundant in female infants at 3–4 months of age, following maternal asthma during pregnancy.

There is growing recognition of the clinical importance of pulmonary haemodynamics during exercise, but several questions remain to be elucidated. The goal of this statement is to assess the scientific evidence in this field in order to provide a basis for future recommendations.

Right heart catheterisation is the gold standard method to assess pulmonary haemodynamics at rest and during exercise. Exercise echocardiography and cardiopulmonary exercise testing represent non-invasive tools with evolving clinical applications. The term “exercise pulmonary hypertension” may be the most adequate to describe an abnormal pulmonary haemodynamic response characterised by an excessive pulmonary arterial pressure (PAP) increase in relation to flow during exercise. Exercise pulmonary hypertension may be defined as the presence of resting mean PAP <25 mmHg and mean PAP >30 mmHg during exercise with total pulmonary resistance >3 Wood units. Exercise pulmonary hypertension represents the haemodynamic appearance of early pulmonary vascular disease, left heart disease, lung disease or a combination of these conditions. Exercise pulmonary hypertension is associated with the presence of a modest elevation of resting mean PAP and requires clinical follow-up, particularly if risk factors for pulmonary hypertension are present. There is a lack of robust clinical evidence on targeted medical therapy for exercise pulmonary hypertension.
Recent advances in managing idiopathic pulmonary fibrosis
Authors: Scelfo Chiara , Caminati Antonella , Harari Sergio
Published: November 2017

Idiopathic pulmonary fibrosis (IPF) is a rare pulmonary disease with a poor prognosis and severe impact on quality of life. Early diagnosis is still challenging and important delays are registered before final diagnosis can be reached. Available tools fail to predict the variable course of the disease and to evaluate response to antifibrotic drugs. Despite the recent approval of pirfenidone and nintedanib, significant challenges remain to improve prognosis and quality of life. It is hoped that the new insights gained in pathobiology in the last few years will lead to further advances in the diagnosis and management of IPF. Currently, early diagnosis and prompt initiation of treatments reducing lung function loss offer the best hope for improved outcomes. This article aims at providing an overview of recent advances in managing patients with IPF and has a particular focus on how to reach a diagnosis, manage comorbidities and lung transplantation, care for the non-pharmacological needs of patients, and address palliative care.

A Rare-Event Simulation Algorithm for Periodic Single-Server Queues
Authors: Ma Ni , Whitt Ward
Published: November 2017

An efficient algorithm is developed to calculate the periodic steady-state distribution and moments of the remaining workload Wy at time yc within a cycle of length c, 0 ≤ y < 1, in a single-server queue with a periodic arrival-rate function. The algorithm applies exactly to the GIt/GI/1 model, where the arrival process is a time-transformation of a renewal process. A new representation of Wy makes it possible to apply a modification of the classic rare-event simulation for the stationary GI/GI/1 model exploiting importance sampling using an exponential change of measure. We establish bounds between the periodic workload and the stationary workload with the average arrival rate that enable us to prove that the relative error in estimates of P(Wy > b) is uniformly bounded in b. With the aid of a recent heavy-traffic limit theorem, the algorithm also applies to compute the periodic steady-state distribution of (i) reflected periodic Brownian motion (RPBM) by considering appropriately scaled GIt/GI/1 models and (ii) a large class of general Gt/G/1 queues by approximating by GIt/GI/1 models with the same heavy-traffic limit. Simulation examples demonstrate the accuracy and efficiency of the algorithm for both GIt/GI/1 queues and RPBM.

Integrated Supply Chain Management via Randomized Rounding
Authors: Pedrosa Lehilton L. C. , Sviridenko Maxim
Published: November 2017

We consider the supply chain problem of minimizing ordering, distribution, and inventory holding costs of a supply chain formed by a set of warehouses and retailers over a finite time horizon, which we call the production and distribution problem. This is a common generalization of the classical metric facility location problem and joint replenishment problem that coordinates the network design and inventory management decisions in an integrated manner. This coordination can represent significant economy for many applications, where network design and operational costs are normally considered separately. This problem is considered when the instances satisfy assumptions such as metric space of warehouse and retailer locations, and monotonic increasing inventory holding costs. In this work, we give a 2.77-approximation based on the randomized rounding of the natural mixed-integer programming relaxation. Also, we give a 5-approximation for the case that objective function includes retailer ordering setup costs.

Avaliação físico-química dos óleos de babaçu (Orbignya speciosa) e coco (Cocos nucifera) com elevado índice de acidez e dos ácidos graxos (C6 a C16)
Authors: Albuquerque Monica Castelo Guimarães
Published: November 2017

Os óleos vegetais apresentam diversas aplicações em processos industriais e por isto tem aumentado constantemente a demanda na utilização de óleos de baixa qualidade, principalmente na produção de biocombustível. O presente trabalho teve por objetivo a avaliação físico-química dos óleos de babaçu (Orbinya speciosa) e coco (Cocos nucifera) de baixa qualidade, como também a obtenção dos ácidos graxos livres de 6 a 16 átomos de carbonos com finalidade de serem utilizados como matéria-prima para a produção de biocombustível. O óleo de babaçu e de coco, como também os ácidos graxos obtidos destes óleos foram caracterizados quanto as suas propriedades físico-químicas e composição em ácidos graxos (utilizando a cromatografia gasosa acoplado à massa). A técnica de RMN foi utilizada para demonstrar a eficiência da destilação fracionada a pressão reduzida na obtenção dos ácidos graxos de cadeia carbônica intermediaria. Os resultados obtidos demonstraram que a baixa qualidade, em termos de avaliação físico-química dos óleos de babaçu e coco interferem diretamente na aplicação industrial, entretanto, estes ácidos graxos podem ser utilizados em cosmético, produtos farmacêuticos e principalmente na produção de combustível, como o bioquerosene. As análises cromatográficas mostraram ainda, que os óleos de babaçu e coco apresentam como ácidos graxos majoritários o ácido láurico (57,5 e 38,6%, respectivamente), enquanto que a fase de topo da destilação do óleo de coco apresentou o ácido caprílico (39,1%) como principal ácido graxo.

O morango é um fruto com rápida perecibilidade, mesmo assim, há poucos trabalhos na literatura a respeito do uso de produtos para aumentar a sua conservação pós-colheita. Assim, o estudo teve o objetivo de avaliar a qualidade e a conservação de frutos de duas cultivares de morango, submetido ao 1-Metilciclopropeno (1-MCP), armazenados sob temperatura refrigerada. Foram avaliadas as cultivares Albion e San Andreas. Os frutos foram colocados em câmaras fechadas e submetidos ao tratamento com 100 nL L-¹ de 1-MCP pelo período de duas horas. Após o período de aplicação, os frutos foram embalados e armazenados sob temperatura de 4º C ± 1ºC e umidade relativa de 90% ± 5% por 24 dias. O delineamento experimental foi inteiramente casualizado com três repetições e oito frutos por parcela, sendo adotado o esquema fatorial 13 x 2 x 2 (13 tempos de avaliação - dias 0; 2; 4; 6; 8; 10; 12; 14; 16; 18; 20; 22 e 24; duas cultivares, Albion e San Andreas;  e  dois tratamentos, tratados com 1-MCP e controle. Os frutos foram avaliados quanto à firmeza, perda de massa, pH, sólidos solúveis, acidez titulável, ácido ascórbico, antocianinas totais e carotenoides totais.  O uso do 1-MCP não foi eficiente em alterar as características de qualidade avaliadas, pois estas evoluíram normalmente, em ambas as cultivares.

The degradation of Cerrado biome has been increasing the demand for high quality tree seedlings, so that it is necessary to understand the nutritional requirements of these plants. Hymenaea courbaril L., known as jatobá, has a wide distribution that makes it an alternative of reforestation of degraded areas. The aim of the experiment was to evaluate H. courbaril initial growth and gas exchange characteristics under different potassium concentrations (K+). The experiment was arranged in a completely randomized design with five treatments (T0- 0, T1- 3, T2- 6, T3-9 e T4- 12 mM of K+) and four repetitions. Growth measurements were carried out every 15 days. SPAD index and gas exchange measurements were evaluated at 0, 30, and 60 days after treatment imposition. At the end of the experimental period, dry matter was evaluated, and root: shoot ratio (R:S) and Dickson quality index (DQI) were calculated The data were subjected to a one-way ANOVA and by Tukey’s test (P<0.05). The growth characteristics did not show significant difference with different concentrations of K+. At 0 and 30 days the photosynthetic traits were not different. However, at 60 days the absent- (T0), lower- (T1), and hyper- (T4) K+ concentration showed a reduction in SPAD index and gas exchanges parameters, confirming the role of this nutrient in the photosynthetic activity. Thus, regardless the K+ doses during 60 days, H. courbaril reached the growth requirements of field plantations. However, after this period the plant survival could be decreased in low K+ availability conditions.
Do Firms Learn more from Exporting to the Developed Markets? Empirical Evidence of Indian Firms
Authors: Sharma Chandan
Published: November 2017

The hypothesis of learning-by-exporting hinges largely based on the argument that the exporters are exposed to knowledge and technology to foreign markets and they learn and become more productive and innovative. However, firms from developing countries not only export to industrialized economies but also to less developed countries. The natural questions arises that what if a firm from developing countries directs its exports to a country at a similar or lower level of technological developed. Would there still be productivity gains to be made? We attempt to test the effects of destination of exports on firms’ productivity and innovation for a sample of the Indian manufacturing firms. Our findings indicate that a positive learning effect is flowing from developed countries to productivity and innovation of the Indian firms. However, in the case of exporting to developing countries including China, we find weak or negative effects. Furthermore, our results also suggest that in-house R&D and foreign technology enhances the absorption capacity of firms, which in turn help firms in learning and gaining through exporting to technologically advanced countries.
Ultrasound-Assisted Enzymatic Synthesis of Poly-ε-Caprolactone: Kinetic Behavior and ReactorDesign
Authors: Gumel A. M. , Annuar M. S. M. , Chisti Y.
Published: November 2017

Lipase-mediated, ultrasound-assisted synthesis of poly-ε-caprolactone was investigated. It was found that ultrasound irradiation helped to improve the rate constant of poly-ε-caprolactone chain propagation (kp) at high initial monomer (ε-caprolactone) concentration. The enhancement of kp ranged from 34% to 46% at 22.5–18.0 M initial monomer concentration, respectively. In a system proned to time-dependent mass-transfer limitation due to polymer chain extension, the acoustic effects could have also allowed the reaction to continue longer compared to non-sonicated process until it became impossible at highly elevated reaction mixture viscosity(>2,000 times increase from initial viscosity). Consequently, it also helped to improve monomer conversion. In a continuous flow polymerization system, a plug flow reactor system is recommended due to its lowest volume for maximum conversion compared to a continuously stirred tank reactor system.
The Right Not to Have Rights: Posted Worker Acquiescence and the European Union Labor Rights Framework
Authors: Lillie Nathan
Published: November 2017

The emergence of the European Union citizenship agenda has mainly taken place along the evolution of mobility rights, with the goal of creating a pan-European labor market. Mobility undermines the nationally embedded notion of industrial citizenship. Industrial citizenship protects workers’ rights and secures their participation in national political systems. The Europeanization of labor markets severs the relationship between state, territory and citizen on which industrial citizenship has been built, undermining worker collectivism and access to representation. This is legitimated in terms of building market-citizenship, i.e., enabling mobile workers as market actors. However, the way mobility is regulated in the EU has the purpose and effect of weakening collective labor institutions, which also undermines workers’ ability to act as autonomous market actors. The same factors which undermine the industrial citizenship of mobile workers also prevent them from being effective free market agents: i.e., they can neither negotiate nor enforce individual contracts effectively in the face of systematic employer fraud and wage theft. The “Arendtian dilemma” of the “right to have rights” — a dilemma that derives from the claim that rights depend on the existence of a political community, which until now is the territorially exclusive nation-state, rather than universal personhood — emerges as industrial citizenship is internationalized. By disembeddeding workers from host-country industrial relations systems, EU regulation provides the social context in which workers’ rights become alienable.
Unionizing Subcontracted Labor
Authors: Shamir Hila
Published: November 2017

Subcontracting — the practice of using intermediaries to contract workers, whether through temp agencies, manpower agencies, franchise, or other multilayered contracting — is an increasingly popular pattern of employment worldwide. Whether justified from a business perspective or not, subcontracting has dire implications for workers’ rights: it insulates the beneficiary of their labor from direct legal obligations to the workers’ wages and working conditions and drastically reduces their ability to effectively unionize. This Article explores the impact of subcontracting on unionization of subcontracted labor. It argues that labor law in most postindustrial developing economies is structured around the Fordist model of production and employment and therefore provides insufficient protections to workers whose employment arrangements deviate from that model.

The Article maps the various hurdles subcontracting poses to unionization. It identifies three main challenges to the basic assumptions that animate traditional labor law: first, that a union has leverage and significant bargaining power vis-à-vis an employer; second, that the union and the employer are repeat players in negotiations, and that accordingly the labor contract is a relational contract in which both parties consider the short and the long term in their calculations; and third, that the bargaining unit represented by the union is relatively easily discernable and relatively stable. The Article argues that subcontracting disrupts all of these assumptions. Accordingly, in order to remain relevant to subcontracted workers, labor law requires adaptations. The Article sketches a preliminary list of existing and potential legal responses to subcontracting that better guarantee subcontracted workers’ rights to unionize. Its main suggestion is to move away from a bilateral towards a multilateral structure of collective agreement bargaining in subcontracting situations. Finally, the Article questions whether law can provide a once-and-for-all solution to the problems posed by subcontracting, and explores the dynamic role of law and unionizing in this context.
In the Time of Plastic Representation
Authors: Warner Kristen J.
Published: November 2017

To many men and women of color, as well as many white women, meaningful diversity occurs when the actual presence of different-looking bodies appears on screen. For them, this diversity serves as an indicator of progress as well as an aspirational frame for younger generations who are told that the visual signifiers they can identify with carry a great amount of symbolic weight. As a consequence, the degree of diversity became synonymous with the quantity of difference rather than with the dimensionality of those performances. Moreover, a paradoxical condition emerges whereby people of color have become more media savvy yet are still, if not more, reliant on overdetermined and overly reductive notions of so-called “positive” and “negative” representation. Such measures yield a set of dueling consequences: first, that any representation that includes a person of color is automatically a sign of success and progress; second, that such paltry gains generate an easy workaround for the executive suites whereby hiring racially diverse actors becomes an easy substitute for developing new complex characters. The results of such choices can feel—in an affective sense—artificial, or more to the point, like plastic.

Black representation, as it's been understood in a popular sense, has been dominated by the circulation of mediated imagery yielding deleterious effects for the groups depicted. The fear of the effects of such “poor” representation has resulted in a set of binary, nonscientific, underdeveloped metrics—positive and negative—that constitute a nebulous catch-all system wherein the characteristics that define each pole on the spectrum shift depending on the era and the expectations of the audience. What marks a representation as “positive” or “negative”? Responses are often aligned with class (good job, education, community minded), behavior (hypersexual, well-spoken, “woke”), or with characterizations of character that either successfully assimilate into normative culture or fail to do so. However, such a scale oversimplifies the complexities of black identity that require audiences, pop culture critics, and scholars to invest in screen characters through experiencing nuances developed over time and ironically reinforces the stereotypes that operate as industry shorthand. The rationale for solely demanding plastic representation is understandable as a sanity-preserving tactic that can also build esteem and confidence, but it is not nearly enough. Meaningful, resonant diversity is a more difficult, underdeveloped approach that requires all stakeholders to think harder about what on-screen difference looks and feels like. But if representation truly matters, then it is an approach worthy of pursuit.
Death Grips
Authors: Gillespie Michael Boyce
Published: November 2017

Black death in contemporary cinema requires understanding how film blackness always means provoking new entangled measures of the aesthetic, political, social, and cultural capacities of black visual and expressive culture. As a result, the critical consequence of film blackness always entails issues of affect, narrativity, visual historiography, and genre/modalities. Black death, then, signifies both the violent injustice of African American deaths and the rendering of death in cinema. Three short films by black women filmmakers represent an ever-growing archive of recent works that merit critical attention as they advance cinematic practices that point to new political philosophies and circuits of knowledge related to black death and film form. Taken together as a “cinema in the wake,” the three—Leila Weefur's Dead Nigga BLVD (2015), Frances Bodomo's Everybody Dies! (2016), and A. Sayeeda Clarke's White (2011)—pose a range of formal propositions about black death that include animation, the racial grotesque, and speculative fiction.

With distinct and compelling conceptions of black death, these three short films are deeply located in their contemporary American moment. Thinking with these films involves thinking through performing objects, the racial grotesque, and the futurity of social deletion. Together these films exquisitely suspend, disrupt, and disturb constituting distinct visual historiographies and strategies. As cinema in the wake, these films are stirred by incitements of film form, materiality, temporality, and conceptions of black being. But, more importantly, to think through black death across the formal experimentation and critical capacities of this work is to contend with an enduring urgency, the precarity of black life.

Two Meetings and a Funeral is an 85-minute historical opus by the artist Naeem Mohaiemen about the rise and fall of the 1970s Third World resistance movements that once threatened the emergent Western neoliberal order. By juxtaposing archival footage with a contemporary walking tour through Algiers, Dhaka, and New York, Mohaiemen asks of the failed socialist movements in the global South: “What went wrong?” In the context of this writer's cinephilia, what drew me to watch and rewatch Naeem Mohaiemen's latest film was not only its timely subject matter but also its wondrous big-screen delivery. Mohaiemen savors the possibilities of an expansive three-screen presentation in high definition with 5.1-surround sound. Which prompts other fundamental questions: What exactly constitutes gallery art and what belongs in a cinema? Where does this expansive, gripping, and elegant piece of filmmaking truly belong?
The Federation of Architects, Engineers, Chemists and Technicians (FAECT):
Authors: Bacon Mardges
Published: November 2017

During the 1930s, as unemployment among architects and draftsmen in the United States reached 90 percent or more, these practitioners joined with other technical workers to form the Federation of Architects, Engineers, Chemists and Technicians (FAECT). From 1933 until after World War II, the FAECT served as a trade union and activist organization for the purpose of securing higher wages, employment benefits, and labor rights. For architectural workers the organization also focused on a commitment to affordable housing and the efficiency of manufactured housing. Through its publications, the FAECT Bulletin and Technical America, the Federation debated key issues and promoted its advocacy to members nationwide. In The Federation of Architects, Engineers, Chemists and Technicians (FAECT): The Politics and Social Practice of Labor, Mardges Bacon examines how the FAECT provides a historical model of solidarity and activism for future practitioners in the architecture profession.
Historical Journals as Digital Sources:

Published: November 2017

Historical Journals as Digital Sources: Mapping Architecture in Germany, 1914–24 demonstrates how historical journals can provide information for digital mapping and how mapping can tell us something new about the German construction industry in a moment of crisis. Digital maps can expand the art historical research process and raise fundamental art historical research questions. Paul B. Jaskot and Ivo van der Graaff developed a database from all issues of the German journal Deutsche Bauzeitung published in the period 1914–24 and visualized the evidence they collected using geographic information systems (GIS) technology. They assess how well the database works for historical analysis and GIS and discuss the indexical possibilities of the digital mapping of historical sources. The visualization of the database gives form to human actions and structural patterns that can redirect the art historical question from individual objects to what construction can tell us about society as a whole. In the process, such visualization allows us to see a much broader history of German architecture, 1914–24.
Framing Landscape While Building Density:
Authors: Bluestone Daniel
Published: November 2017

In the late nineteenth and early twentieth centuries, Chicago developers, architects, and residents defined a new residential vernacular: brick courtyard apartments, which massed units in low-rise buildings around landscaped courtyards, often open to the street. These buildings accommodated higher levels of residential density and seemingly did the opposite as well—preserved and cultivated nature. The Chicago courtyard apartment creatively negotiated the social and cultural tension between reverence for the iconic single-family house and an urban society increasingly occupying multiple-unit dwellings. The designs drew upon the interest in sunlight, air circulation, and natural landscape that influenced contemporary tenement house reform, urban hospital design, the small park and playground movement, and the rethinking of the dimensions and possibilities of residential lawns and gardens. In Framing Landscape While Building Density: Chicago Courtyard Apartments, 1891–1929, Daniel Bluestone looks closely at specific Chicago courtyard apartments, unpacking the design and cultural logic at play in their construction.
Growth and development of the organism and immunophysiological indices of blood of male F2 rats, affected by different doses of nanogermanium citrate
Authors: Fedoruk R. , Tesarivska U. , Khrabko M. , Tsap M.
Published: November 2017

Aim. To study age-related changes in the bodyweight, internal organs, and immunophysiological indices of blood for male F 2 rats, affected by different doses of nanogermanium citrate. Methods. Physiological, immunological, clinical, colorimetric, and statistical methods were applied; automatic veterinary analyzer Orphee Mythic 18 Vet (Germany) was used to determine hematological indices. Results. The decade-wise dynamics of changes in the bodyweight, the weight of heart, liver, kidneys, testicles, lungs, spleen, and weight coeffi cients of these organs at the age of 2–3 and 4–5 months demonstrated that there were intergroup dose-dependent and age-related differences in the intensity of growth and development of the organism of male rats. The highest gain of bodyweight was registered for male rates, which received 10 μg Ge/kg of bodyweight 30 days after weaning, this tendency was kept for the lower level of these indices in groups ІІІ and IV at the effect of 20 and 200 μg Ge. On days 97, 107, and 117, males
of group II and IV demonstrated non-reliably lower indices of bodyweight, whereas in group III their values did not differ much from those for the control. Reliably higher indices of weight of liver and spleen were demonstrated along with their weight coeffi cients for younger males, but they were lower at the age of 4–5 months compared to the control. The blood of 2–3 m.o. group II males had reliably lower content of hemoglobin and hematocrit index as well as the tendency to the decrease in the number of erythrocytes. At the age of 4–5 months, there was an evident decrease in the number of leukocytes and their forms – lymphocytes, monocytes, and granulocytes, which was more expressed in the blood of group II and IV males compared to the control. At the impact of nanogermanium citrate (NGeC), the blood of males of experimental groups of both age periods demonstrated higher content of immunoglobulins, circulating immune complexes, hexoses, bound to proteins, and ceruloplasmin (except for group II animals at
the age of 4 months). The effect of applied doses of NGeC inhibited the input of acute phase proteins into the blood which was evident in the reliably lower content of mean mass molecules at the age of 2–3 months with its staying at the level of the control group of animals at the age of 4– months. Conclusions. The biological effect of NGeC in the doses of 10, 20, and 200 μg Ge/kg of bodyweight was demonstrated in differently directed changes in the intensity of organism growth and development, specifi c internal organs, and hematological indices, which was more expressed for animals, receiving 10 μg Ge, as well as in the differences in immunophysiological indices of blood of males of the experimental groups of both age periods, which indicated the activation of immunobiological reactivity of their organism at the age of 2–3 and 4–5 months.

PCR-screening of samples of bovine peripheral blood, subject to diagnostic studies of leukemia, from the farms in the Eastern Ukraine (Kharkiv and Sumy regions). Methods. The genetic material of agents of retroviral infections in clinical samples was detected via conventional PCR and real-time PCR. Results of Investiga- tions. The presence of BLV-, BIV-, BFV-infected animals among livestock was established. The number of animals, infected with leukemia, was 57–100 % from the total number of examined livestock on average. The presence of genetic material of BIV virus was either not detected at all, or detected in the amount of 62 % from the number of tested animals. At the same time, the presence of genetic material of BFV was in the range of 61.5–81 % from the total number of studied samples. A possible connection between the viruses of leukemia, immunodefi ciency and foamy virus of cattle, circulating among the livestock in the farms of the Eastern region of Ukraine, was also established. Conclusions. The presence of genetic material of immunodefi ciency virus in the leukemia-positive samples was insignifi cant – only 4 samples, whereas the presence of the foamy virus in the leukemia-positive samples was detected in 51 samples, which was 3 % and 42 % from the total number of investigated samples respectively. The absence of leukemia virus in the blood samples, containing the DNAs of two other minor retroviruses, was detected in one sample (0.8 %). The simultaneous presence of all three agents of retroviral infections was established in 36 samples (30 %).
Síntesis y caracterización de las propiedades ópticas de puntos cuánticos de CdSe y CdSe/ZnS

Se prepararon puntos cuánticos de CdSe y CdSe/ZnS (núcleo/capa) con ácido oleico como agente estabilizante en medio orgánico y se examinan las propiedades ópticas de los nanocristales obtenidos. En la obtención de CdSe, se estudió la influencia del O2 en la cinética de crecimiento de los puntos cuánticos. Durante los primeros 90 s, el crecimiento de los nanocristales en presencia de O2 fue 1,6 veces mayor que en atmósfera inerte. A pesar de este rápido crecimiento, el O2 afectó las propiedades ópticas de los nanocristales, formando bandas de absorción anchas y espectros de fluorescencia de baja intensidad. En2contraste, los puntos cuánticos de CdSe sintetizados en atmósfera inerte presentaron picos de absorción bien definidos y fluorescencia aguda e intensa. Estas propiedades se intensificaron con la formación de un 10% de la monocapa de ZnS: para un núcleo de 2.50 nm, el rendimiento cuántico de fluorescencia (ΦFl) en la región del verde se incrementó de 5,5 % a 42,3%. El procedimiento de síntesis de nanocristales de CdSe/ZnS desarrollado con baja concentración de Zn2+ y con un exceso de S2- puede emplearse en la obtención de materiales con excelentes propiedades fotoluminiscentes para aplicaciones como biomarcadores, sensores, catálisis y celdas solares.

Introducción. Cualquier levantamiento por encima del plano normal de la mucosa colónica es considerada proyección polipoidea. A mayor edad es más probable encontrar pólipos; además, los >1 cm de diámetro tienen mayor potencial de desarrollar neoplasia maligna.Objetivo. Establecer la frecuencia de lesiones polipósicas del colon, su tamaño, su localización y los grupos de edades donde están presentes en pacientes a quienes se les realizó colonoscopia en el Hospital Departamental de Villavicencio en el periodo 2009-2014.Materiales y métodos. Se analizaron los resultados de 411 colonoscopias diagnósticas. La recolección de datos y descripción estadística se hizo con el software SPPSS 2011.Resultados. Del total de la muestra, 43 (10.46%) pólipos fueron ≤1cm de diámetro, 16 (4% 3.89%) estuvieron entre 1cm y 2cm, no se encontraron pólipos >2cm y en el resto de resultados no se hallaron estas anomalías. En el grupo de edad de 41 a 50 años se presentaron pólipos en todos los segmentos del colon, pero el de mayor porcentaje (11%) fue el de 71 a 80 años. En el colon izquierdo se presentó el 69% de los pólipos >1cm y el 67% de los <1cm.Conclusión. En grupos de poblaciones <40 años de edad, los hallazgos de pólipos son bajos en colon izquierdo y muy bajos en colon derecho.

El cólico del lactante es uno de los principales motivos de consulta en los servicios de pediatría, gastroenterología y nutrición pediátrica. Esta patología posee múltiples características etiológicas como disfunción de la mecánica familiar, alteraciones gastrointestinales, alergias o intolerancias alimentarias, desbalance alimentario e inadecuados hábitos alimenticios. Es de carácter agudo, con inicio súbito que tiende a desaparecer entre los 3 y 6 meses de edad. Hasta el momento no existe un consenso sobre los protocolos de manejo de esta condición o sobre sus indicadores de eficacia terapéutica. Desde hace algunos años se han desarrollado fármacos, regímenes dietarios y complementos alimentarios específicos para esta patología (anticólico). Este trabajo es una revisión de la evidencia sobre los fundamentos y avances en el tratamiento del cólico del lactante en el que se recopilan las características de esta patología, las medidas terapéuticas médicas y nutricionales, el abordaje clínico y las técnicas para ayudar al paciente y su entorno familiar. El presente estudio busca brindar herramientas técnicas al profesional de la salud cuya población objeto de atención es menor de 2 años.

Published: November 2017

Introducción. El enfoque intercultural hacia las comunidades nativas americanas requiere el conocimiento de los conceptos y las prácticas que favorecen o perjudican la salud de estas poblaciones desde su propia perspectiva.Objetivo. Comprender el significado de salud y salud mental que circula en las narrativas de la comunidad reetnizada indígena muisca de Cota y el potencial de la musicoterapia comunitaria para promoverlas.Materiales y métodos. Estudio de caso con enfoque cualitativo tipo investigación social de segundo orden. Para la recolección de datos se utilizó cartografía social, entrevistas a profundidad, grupos focales, observación participante y proceso musicoterapéutico.Resultados. La comunidad maneja un concepto de salud diferente al de la sociedad mayoritaria. No hay división entre los conceptos de salud y salud mental. La música está integrada a las actividades comunitarias y de sanación.Conclusiones. La reetnización es una decisión política con implicaciones culturales, organizativas y de salud. Las comunidades reetnizadas no pueden ser equiparadas con la sociedad dominante ni con otros grupos indígenas en cuanto a decisiones en salud. La salud pública requiere un diálogo intercultural que permita el trabajo adecuado con estas comunidades.
