EFEITO DA MANIPULAÇÃO ILÍACA - SACRA E SUA RELAÇÃO COM POSSÍVEIS ALTERAÇÕES ASCENDENTES EM ATLETAS DE FUTEBOL

No Brasil o futebol e o principal esporte e vem sofrendo mudancas nos ultimos anos, obrigando os atletas a trabalharem em seus limites, aumentando as chances de lesao. Os exageros dos movimentos fisiologicos podem acarretar disfuncoes nas articulacoes. Sabe-se que os pes sao extremamente exigidos e os diferentes tipos de pe sao responsaveis por alteracoes plantares e serao sempre responsaveis pelo mau posicionamento da pelve. O estudo objetivou identificar, disfuncoes iliacas, trata-las e analisar sua influencia sobre a morfotipologia plantar. Participaram do estudo 20 atletas de futebol do sexo masculino da categoria de base do Americano Futebol Clube. O estudo caracterizou-se como observacional serie de casos. Realizaram-se testes ortopedicos a fim de diagnosticar disfuncao iliaca. Em seguida realizou-se manipulacao osteopatica pela tecnica direta do iliaco, sendo reavaliado em sequencia. Apos manipulacao realizou-se plantigrafia para reavaliacao da morfotipologia plantar. Para analise dos dados obtidos na plantigrafia utilizou o software Microsoft Excel 2007 e o Bioestat 5.0 para a tabulacao dos dados e analise estatistica. Apos analise da biomecânica iliaca constatou-se que 15 dos 20 atletas apresentaram disfuncao iliaca e que 53% desses atletas apresentaram lesao em hemipelve posterior. Atraves da plantigrafia nao observou-se mudanca significativa (p>0,05) em relacao ao istmo. Os resultados obtidos permitiram a conclusao de que as tecnicas de manipulacao utilizadas sao eficazes na recuperacao da mobilidade imediata das articulacoes. Em relacao a morfotipologia plantar e alteracoes da area de contato, os resultados nao tem relevância significativa (p>0,05).
The effects of an antiserum to the contractile proteins of the heart on the developing rat embryo.

An antiserum with specific reactivity against the contractile proteins of the rat heart has been raised in the rabbit. Fractions of the serum have been shown to enter the isolated rat embryo by electron-microscopic studies with ferritin, where they bind to the myocardium, producing degenerative changes. Both IgG and IgM fractions are toxic, producing foetal death in a large proportion of explanted embryos.
AutoPilot: experiences implementing a distributed data-driven agent architecture

Self-directed mobile software agents are a comparatively recent architectural design model. Mobile software agents, coupled with two other design metaphors, Place (or Service Provider) and Trader (or Yellow Pages Directory), can be used to construct processing architectures which are scalable, flexible, and extensible. Certain workflow problems (text processing and dissemination, claims processing) in which the potential processing paths through a routing domain are initially indeterminate seem especially well suited to an Agent-Place-Trader design architecture. This paper motivates the architecture with a description of challenges inherent in the functional requirements of a text processing and dissemination system. The paper continues with a description of our prototypes design, implementation, and object oriented tools used. An analysis of the benefits and limitations of using various agent systems in conjunction with the C++ and Java programming languages is presented. The authors draw conclusions regarding architectures for dynamic distributed processing in general and workflow problems in particular.
Coping Style as a Mediator between Attachment and Mental and Physical Health in Patients Suffering from Morbid Obesity

Objective: The presence of mental health problems and limitations in physical functioning is high in patients suffering from morbid obesity. The purpose of the current study was to examine the mediating role of coping style in the relationship between attachment representations and mental health and physical functioning in a morbidly obese population. Method: A total of 299 morbidly obese patients who were referred to the Slotervaart bariatric surgery unit in Amsterdam, the Netherlands, completed self-report questionnaires assessing adult attachment style (Experiences in Close Relationship—Revised Questionnaire), coping style (Utrecht Coping List), and patients physical functioning and mental health (Short Form-36). Results: Attachment anxiety (β = –.490, p < .001) and attachment avoidance (β = –.387, p < .001) were both found to be related to mental health. In addition, attachment anxiety was also found to be related to physical functioning (β = –.188, p < .001). Coping style partly mediated these associations. Conclusions: Findings suggest that coping mediates the association between attachment anxiety and attachment avoidance on the one hand and mental health and physical functioning in patients with morbid obesity on the other hand.
Short-term treatment with alcohols causes hepatic steatosis and enhances acetaminophen hepatotoxicity in Cyp2e1(-/-) mice.

CYP2E1 has been reported to have an essential role in alcohol-mediated increases in hepatic steatosis and acetaminophen hepatotoxicity. We found that pretreatment of Cyp2e1(-/-) mice with ethanol plus isopentanol, the predominant alcohols in alcoholic beverages, for 7 days resulted in micro- and macrovesicular steatosis in the livers of all mice, as well as a dramatic increase in acetaminophen hepatotoxicity. In Cyp2e1(-/-) mice administered up to 600 mg acetaminophen/kg alone and euthanized 7 h later, there was no increase in serum levels of ALT. In Cyp2e1(-/-) mice pretreated with ethanol and isopentanol, subsequent exposure to 400 or 600 mg acetaminophen/kg resulted in centrilobular necrosis in all mice with maximal elevation in serum levels of ALT. Acetaminophen-mediated liver damage was similar in males and females. Hepatic microsomal levels of APAP activation in untreated females were similar to those in males treated with the alcohols. However, the females, like the males, required pretreatment with the alcohols in order to increase APAP hepatotoxicity. These findings suggest that, in the Cyp2e1(-/-) mice, the alcohol-mediated increase in acetaminophen hepatotoxicity involves the contribution of other factors, in addition to induction of CYP(s) that activate acetaminophen. Alternatively, CYP-mediated activation of acetaminophen measured in vitro may not reflect the actual activity in vivo. Our findings that a 7-day treatment with ethanol and isopentanol causes extensive hepatic steatosis and increases acetaminophen hepatotoxicity in Cyp2e(-/-) mice indicate that CYP2E1 is not essential for either response.
A broadband wireless access network based on mesh-connected free-space optical links

Driven by the twin forces of industry-wide deregulation and the explosive demand for Internet access and bandwidth-intensive multimedia services, broadband local access has emerged as one of the key issues in modern telecommunications. We describe a broadband local access network consisting of small, densely spaced packet-switching nodes interconnected by focused free-space optical links in a multihop mesh arrangement. Each switch serves a client, which may be an office building (containing, for example, conventional PBXs and LANs), a picocellular base station, or both. It is the responsibility of our local access network to economically and reliably extend broadband local access service (perhaps OC-3 or OC-12 for building LANs and PBXs; perhaps several tens of megabits per second to base stations) from an infrastructure end office or fiber ring add/drop multiplexer without requiring the installation of new buried optical cabling. Computed is the capacity of the multihop mesh, defined to be the maximum number of virtual connections which can be delivered to the infrastructure access point such that, independent of the traffic distribution among clients, all quality of service guarantees are maintained.
Optimal Control over the InAs Nanowire Growth for System Integration and their Structural and Transport Properties

We present new fundamental insights into the nucleation and evolution of InAs nanowires (NWs) grown using organo-metallic vapor-phase epitaxy (OMVPE), the correlation of their room temperature transport behavior with their structural properties, and a novel scheme for their integration to Si substrates. We experimentally distinguish, for the first time, two NW growth regimes defined by the direction of In adatom exchange between the NW (InAs) and the substrate (InAs (lll)B). This understanding leads to optimal control over the NW morphology over length scales of the order of the In adatom surface diffusion length on the NW sidewalls. Transmission electron microscopy (TEM) analysis of the NW crystal structure of wurtzite (WZ) and zincblende (ZB) NWs is used to explain striking differences in their transport behavior. We find that the presence of small ZB sections in the WZ NWs can create spontaneous polarization sheet charges at each section interface along the NW channel, leading to improved subthreshold characteristics over those of pure ZB NWs, as observed in our electrical device measurements. Finally, we successfully demonstrate the vertical integration of electrically isolated InAs NWs on SiO2 on Si suitable for implementing 3D NW circuits using the bottom-up synthesis approach for practical integration of III-V functional devices to Si technology.
EMF hyperthermia in children

Combination of multimodality therapy with regional hyperthermia is a rewarding method to improve local tumor control rate and long term survival in children with high-risk tumors with dismal prognosis. Hyperthermia helps chemo refractory tumors to overcome their resistance to earlier applied chemotherapy. High quality hyperthermia is associated with treatment outcome and hence technological innovation will contribute to further enhance treatment outcome. Multiple channel heat applicators and non-invasive MR temperature monitoring for childhood cancer can produce precise target volumes with substantial sparing of normal tissue.
Static Physically Unclonable Functions for Secure Chip Identification With 1.9–5.8% Native Bit Instability at 0.6–1 V and 15 fJ/bit in 65 nm

A novel class of mono-stable static physically unclonable functions (PUFs) for secure key generation and chip identification is proposed. The fundamental concept is demonstrated through a 65 nm prototype that contains two different implementations, as well as several previously proposed PUFs to enable a fair comparison at iso-technology. From a statistical quality viewpoint, the achieved reproducibility and uniqueness are quantified by an intra-PUF Hamming distance (HD) lower than 1 and an inter-PUF HD of 128.35, for a 256-bit PUF output key. The keys generated by the proposed PUF pass all applicable NIST randomness tests. The measured energy per bit is as low as 15 fJ/bit. Native unstable bits are less than 2% at nominal conditions, less than 5% at 0.6-1 V and less than 6% in worst case scenario of 0.6 V voltage and 85 °C temperature, before applying any further post-silicon technique for stability enhancement.
Quantifying the relative importance of land cover change from climate and land use in the representative concentration pathways

Climate change is projected to cause substantial alterations in vegetation distribution, but these have been given little attention in comparison to land use in the Representative Concentration Pathway (RCP) scenarios. Here we assess the climate‐induced land cover changes (CILCC) in the RCPs and compare them to land use land cover change (LULCC). To do this, we use an ensemble of simulations with and without LULCC in Earth System Model HadGEM2‐ES (Hadley Centre Global Environmental Model 2) ‐ for RCP2.6, RCP4.5, and RCP8.5. We find that climate change causes an expansion poleward of vegetation that affects more land area than LULCC in all of the RCPs considered here. The terrestrial carbon changes from CILCC are also larger than for LULCC. When considering only forest, the LULCC is larger, but the CILCC is highly variable with the overall radiative forcing of the scenario. The CILCC forest increase compensates 90% of the global anthropogenic deforestation by 2100 in RCP8.5 but just 3% in RCP2.6. Overall, bigger land cover changes tend to originate from LULCC in the shorter term or lower radiative forcing scenarios and from CILCC in the longer term and higher radiative forcing scenarios. The extent to which CILCC could compensate for LULCC raises difficult questions regarding global forest and biodiversity offsetting, especially at different time scales. This research shows the importance of considering the relative size of CILCC to LULCC, especially with regard to the ecological effects of the different RCPs.
The impact of sociodemographics, comorbidity and symptom recency on health-related quality of life in alcoholics.

OBJECTIVE To obtain estimates of the relationship between alcoholism and health-related quality of life (HRQL) in twin pairs discordant for alcohol dependence. METHOD In 1995, 1,258 male-male twin pair members of the Vietnam Era Twin Registry (total Registry N = 7.375 pairs) were administered a modified Medical Outcomes Study 36 Item Short Form (SF-36) and the Diagnostic Interview Schedule (DIS) to obtain measures of HRQL and a DSM-III-R criteria lifetime diagnosis of alcohol dependence. Mean within pair differences on eight separate SF-36 subscales were calculated for 436 remitted (no alcohol symptoms in the past 5 years) alcohol-dependent discordant twin pairs and for 194 recent (at least one alcohol symptom in the past 5 years) alcohol-dependent discordant pairs before and after adjustment for covariates. Covariates included lifetime physical illness, lifetime psychiatric disorders, lifetime drug dependence, lifetime nicotine dependence, current marital status, current income and severity. RESULTS In the unadjusted analysis remitted alcoholic twins compared to their nonalcoholic co-twins reported significantly lower mean scores for six of eight SF-36 subscales. Recent alcoholic twins, compared to their nonalcoholic co-twins, reported significantly lower mean scores for all of the SF-36 subscales. However, after simultaneous adjustment for all covariates, no SF-36 subscale mean, except "vitality" among recent alcoholic twins, was significantly different between alcoholic twins and their nonalcoholic co-twins. CONCLUSIONS Differences in HRQL between alcoholic and nonalcoholic co-twins is due to covariation from physical and psychiatric problems, drug and nicotine dependence, marital status, income and severity.
Characteristics of HIV‐1 gp120 glycoprotein binding to glycolipids

We examined the binding of the gp120 envelope glycoprotein (gp120) of the human immunodeficiency virus (HIV‐1) to sulfatide (GalS), galactocerebroside (GalC), and GMI‐ganglioside (GMI). The gp120 glycoprotein bound to GalS but not to GalC or GMI by enzyme‐linked immunosorbent assay (ELISA) and by an immunospot assay on nitrocellulose paper. However, it bound to all three glycolipids by an immunospot assay on thin layer chromotography (TLC) plates. In studies to determine whether GalS could be a receptor for gp120 on the surface of cells, gp120 bound to GalS incorporated into the plasma membrane of lymphoid cells as determined by cytofluorometric analysis and immunofluorescence microscopy. These studies indicate that GalS may function as a receptor for gp120 and HIV‐1. © 1994 Wiley‐Liss, Inc.
Apoptosis in Feline Panleukopenia Virus-Infected Lymphocytes

ABSTRACT Feline panleukopenia virus (FPLV) was shown to induce apoptosis to feline lymphoid cells and to reduce the expression of interleukin-2 receptor α on the cells. FPLV-induced apoptosis might be a key element in the pathophysiology of atrophy of lymphoid tissues associated with feline panleukopenia caused by FPLV.
Essential thrombocythemia: A clonal disorder of hematopoietic stem cell

We studied 5 patients with essential thrombocythemia utilizing glucose‐6‐phosphate dehydrogenase (G‐6‐PD) enzyme as a cell marker for determining clonality. One of the patients was found to be heterozygous for isoenzymes B and A in the nonhaemopoietic tissues such as fibroblasts, but manifested only isoenzyme type B in the erythrocytes, neutrophils, and platelets. Our studies support the concept that essential thrombocythemia is a clonal disorder arising in a multipotent stem cell.
Determinants of unemployment in Ghana

Unemployment is often cited as a measure of the low employment content of Ghana's strong growth performance over the past three decades. The paper presents evidence to suggest that employment growth in Ghana continues to trail economic growth due to high growth of low employment generating sectors against sluggish growth of high labour absorption sectors. A cross-sectional estimation of a probit regression model also indicates a strong effect of demand factors on unemployment, indicating a weak employment generating impact of economic growth. Empirical analysis also confirms higher vulnerability of youth and urban dwellers to unemployment with education and gender explaining unemployment in some instances. Reservation wage is also observed to have an increasing effect of unemployment. The paper recommends policies that promote investment in agriculture and manufacturing which is associated with higher employment elasticity of output. High incidence of unemployment among the youth and secondary school leavers in the most recent period requires targeted intervention including support for entrepreneurial training and start-up capital to attract young school leavers to become ‘creators’ rather than ‘seekers’ of jobs. A downward review of expectations on the part of jobseekers in terms of their reservation wage could help reduce unemployment in Ghana.
Methods for capture–recapture analysis when cases lack personal identifiers

Methods for estimating the size of a closed population from a capture–recapture study require the availability of unique identifiers on each of two lists. These identifiers are used to identify the number of individuals appearing on both lists. When the number of individuals appearing on both lists cannot be determined with certainty from the data, matching between the lists is problematic. In this paper, we develop a weighted estimator to account for all possible matches between two lists. A bootstrap procedure is proposed for estimation. To illustrate the methods, we used two lists that recorded New York State (NYS) hospitalizations due to pertussis in 1996 to estimate the number of persons hospitalized for pertussis in NYS that year.

Low Complexity Channel Estimation for Minimizing Edge Effects in OFDM Systems

Channel estimation is critical to receiver performance in an OFDM system. Pilot symbols are typically interspersed with data symbols among the sub-carriers to aid channel estimation. Standard algorithms to estimate the channel based on these pilot symbols include minimum mean-square error (MMSE) and maximum-likelihood (ML) estimation. With a uniform density of pilots in frequency among the sub-carriers, the ML estimate exhibits a boundary effect whereby the quality of the estimates on sub-carriers towards the edges of the signal band degrades. While the use of MMSE mitigates this effect significantly it requires precise knowledge of channel statistics which are difficult to obtain. Also, it is often too complex to implement for common numbers of sub-carriers. This paper proposes mitigation of the boundary effect described above by transmitting extra pilot symbols in the sub-carriers towards the edges of the band in addition to the regularly spaced pilots, thereby increasing pilot density at the edges. Channel estimation is performed using a two-step algorithm. ML estimates are first formed using the uniform pilot set. The output of the ML estimator is then used to bias an MMSE estimator which is applied only to the edge pilot set. The two-step approach enhances performance as compared to ML estimation while keeping complexity much lower than that incurred when MMSE is used across the entire band.
Relationships among the results of coagulase, staphylococcal toxin, and thermonuclease tests on staphylococci from cow milk

Production of staphylococcal alpha- or alpha-beta-toxins correlated well with production of coagulase or thermonuclease (or both) in 203 Staphylococcus aureus isolates from milk and should be reliable indicators of S. aureus in the absence of Staphylococcus intermedius. Failures to produce toxin, tube coagulase, or thermonuclease occurred in only 1 to 2% of S. aureus. Evidence of beta- or alpha-beta-toxins was not found among 321 other staphylococci isolated from milk. A few coagulase- or thermonuclease-positive isolates not producing beta- or alpha-beta-toxins were found among the Staphylococcus hyicus isolates.
China's reforms: A mixed legacy for a new generation

L'A. propose un regard retrospectif sur le cours du programme de reforme economique des ving-cinq dernieres annees en Chine afin d'identifier les defis que devra affronter la nouvelle generation des leaders chinois. Alors que celle-ci se prepare a assumer le pouvoir au XVI eme Congres du Parti communiste, il est clair qu'elle herite d'un double legs de succes notables et de difficultes embarrassantes. D'une part, les reformes ont permis une croissance elevee, generant un meilleur niveau de vie et de nouvelles opportunites. L'ouverture de la Chine au monde s'est confirmee par son nouveau statut de puissance economique majeure. D'autre part, les reformes les plus radicales ont ete contenues, notamment en raison de la crainte de troubles sociaux. Le changement social et la diversite croissante de la societe chinoise engendres par la reforme constituent peut-etre le defi le plus important pour le nouveau leadership.
A Statistical Approach to Robust Video Temporal Indexing and Segmentation

For video indexing, the problem of video cut detection remains largely an open problem because of the wide nature of transitions that occur in a digital video. This paper describes a shot boundary detection technique, which is an amalgamation of few statistical methods and measures, and robustly detects camera breaks in a full-motion video clip. The proposed algorithm incorporates a weighted histogram, an error-propagation technique for increased robustness, and a curve-fitting technique to extract partitions from the similarity curve for avoiding heuristically chosen threshold value. The algorithm has been validated on many video clips and is shown to give improved results, including for videos with rapid scanning, changes in illumination, fade-ins and fade-outs, and with special effects like dissolve and filters.
