OBJECTIVE: To assess the association between primary tooth eruption and the manifestation of signs and symptoms of teething in infants. METHODS: An 8-month, longitudinal study was conducted with 47 non-institutionalized infants (ie, receiving care at home) between 5 and 15 months of age in the city of Diamantina, Brazil. The nonrandomized convenience sample was based on the registry of infants in this age range provided by the Diamantina Secretary of Health. Eligible participants were infants with up to 7 erupted incisors and no history of chronic disease or disorders that could cause an increase in the signs and symptoms assessed in the study. Tympanic and axillary temperature readings and clinical oral examinations were performed daily. A daily interview with the mothers was conducted to investigate the occurrence of 13 signs and symptoms associated with teething presented by the infants in the previous 24 hours. RESULTS: Teething was associated with a rise in tympanic temperature on the day of the eruption (P = .004) and with the occurrence of other signs and symptoms. Readings of maximal tympanic and axillary temperatures were 36.8° C and 36.6° C, respectively. The most frequent signs and symptoms associated with teething were irritability (median: 0.60; P < .001), increased salivation (median: 0.50; P < .001), runny nose (median: 0.50; P < .001), and loss of appetite (median: 0.50; P < .001). CONCLUSIONS: Irritability, increased salivation, runny nose, loss of appetite, diarrhea, rash, and sleep disturbance were associated with primary tooth eruption. Results of this study support the concept that the occurrence of severe signs and symptoms, such as fever, could not be attributed to teething. Copyright © 2011 by the American Academy of Pediatrics.

Obesity is a disease characterized by the excessive accumulation of corporal fat, which produces deleterious effects to the health. There is consent in the literature that its etiology is multifactorial, involving biological, historical, ecological, political, social-economical, psychosocial and cultural aspects. In that sense, this article's objective is to talk about the multi-factorial character of obesity, involving the wide variety of environmental and genetic factors implicated in its etiology, starting from secondary studies of literature revision in the main bases of data and specialized libraries. Nowadays, obesity has been considered the most important nutritional disorder in the developed countries and the ones in development, due to the increase of its incidence. The approach of the genetic, metabolic, psychosocial, symbolic, and cultural aspects in addition to the lifestyle allowed to base obesity as a plural illness, and showed the necessity to create public politics with multidiscipline and inter-sectorial actions, that value the partnership between government and civil society, in the prevention and combat of obesity and the promotion of health, making possible the community's participation in that process, through responsibility and self care.

Lead dioxide microfibers (MF-PbO 2) were electroformed on fibers of a carbon cloth substrate in order to obtain a porous gas-evolving anode (PGEA). A solid polymer electrolyte cell was fabricated using perforated current collectors, composed of PGEA pressed against the solid polymer electrolyte using a stainless steel fine mesh as the cathode. Ex situ characterization carried out through XRD and SEM techniques provided information about the structural and morphological properties of the MF-PbO 2, respectively. An electrochemical characterization study was carried out through analysis of the quasi-stationary polarization curves obtained for the oxygen evolution reaction (OER). Analysis of SEM images showed that the MF-PbO 2 surface is rough and uniformly distributed along fibers of the carbon cloth substrate. The formation of MF-PbO 2 occurred preferentially onto carbon fibers located near the surface of the substrate (outer fibers). The XRD study revealed a high degree of crystallinity of the beta phase (β-PbO 2), with crystals characterized by a size of 24 nm. Analysis of the Tafel plot permitted us to propose the primary water discharge as the rate-determining step for the OER. The apparent enthalpy and entropy of activation and the apparent kinetic rate constant were evaluated for the OER on MF-PbO 2. The endurance test revealed that MF-PbO 2 are resistant to wear during the intense oxygen evolution. © 2012 Elsevier Ltd. All rights reserved.

Micromagnetic simulations have been used to investigate the magnetization reversal in ultrathin Fe/Rh/FeCo trilayer. The influence of parameters like interlayer magnetic couplings, density of spin-current, and applied magnetic fields was studied. The technological interest on this system comes from the possibilities of stabilization of a nonorthogonal configuration of the magnetizations of the Fe and FeCo layers, recently achieved experimentally. The calculations presented in this work show that this particular magnetization configuration reduces the switching time as compared to the case where both layers have perpendicular magnetic anisotropy. The reversal promoted by pure electrical current (via spin-transfer torque), pure static magnetic field, and a combination of field and current were simulated. It has been found the configurations providing the shortest switching time are the ones with the Fe layer easy direction along [1 1 1] or [1 0 1] and with the FeCo layer presenting perpendicular magnetic anisotropy. © 2016 Elsevier B.V.

The genus Plesiophrictus is diagnosed and redescribed based on type material and additional specimens. The type species P. millardi (Pocock 1899) is redescribed. The genus Heterophrictus is revalidated, with H. milleti as type species. Heterophrictus differs from Plesiophrictus by the absence of serrula on maxillae and by having a rastellum on the chelicerae and stiff, spike-shaped setae on the prolateral coxae I. The significance of characters used in the taxonomy of both genera is discussed. © 2011 The American Arachnological Society.

This paper investigates the viability of using the dynamic Bayesian Network framework as a tool to classify heart beats in long term ECG records. A Decision Support System composed by two layers is considered. The first layer performs the segmentation of each heartbeat available in the ECG record, whereas the second layer classifies the heartbeat as Premature Ventricular Contraction (PVC) or Other. The use of both static and dynamic Bayesian Networks is evaluated through using the records available in the MIT-BIH database, and the results show that the Dynamic one performs better, obtaining 95% of sensitivity and 98% of positive predictivity, showing that to consider the temporal relation among events is a good strategy to increase the certainty about present events.

Type II dentinogenesis imperfecta (DGIII) is an autosomal dominant dental development anomaly that affects both the primary and permanent dentition. This case report describes the clinical, radiographic and morphological characteristics of the teeth of a seven-year-old child with DGI-II determined by optical microscopy and scanning electron microscopy. This consisted of extraction of the primary teeth with periapical lesions due to the advanced state of tooth resorption. Aesthetic restorations were performed on the mandibular anterior teeth and occlusal fissure sealants were applied to erupting teeth. A removable partial upper denture was made in order to return anterior aesthetic function and to aid mastication and speech. FOLLOW UP: The child was examined at 3 month intervals. Over the following 3 years the prosthesis was replaced due to facial growth and fluoride was applied at each follow-up visit to all teeth. The patient remains in follow up and management. Individuals with DGI-II must not neglect their dental health. Early diagnosis, professional advice and treatment with periodic follow-up can help improve the quality of life of such patients.

The purpose of this study was to assess the validity of the Human Activity Profile (HAP) by comparing scores with accelerometer data and by objectively testing its cutoff points. This study included 120 older women (age 60-90 years). Average daily time spent in sedentary, moderate, and hard activity; counts; number of steps; and energy expenditure were measured using an accelerometer. Spearman rank order correlations were used to evaluate the correlation between the HAP scores and accelerometer variables. Significant relationships were detected (rho = .47-.75, p < .001), indicating that the HAP estimates physical activity at a group level well; however, scatterplots showed individual errors. Receiver operating characteristic curves were constructed to determine HAP cutoff points on the basis of physical activity level recommendations, and the cutoff points found were similar to the original HAP cutoff points. The HAP is a useful indicator of physical activity levels in older women.

The genus Oligoxystre was originally established in 1924 for O. auratum Vellard 1924 from southern state of Gois, Central Brazil. Today, the genus includes seven species: O. auratum, O. caatinga Guadanucci 2007, O. bolivianum (Vol 2001), O. tucuruiense Guadanucci 2007, O. rufoniger Guadanucci 2007, O. dominguense Guadanucci 2007, and O. diamantinensis Bertani et al. 2009. Oligoxystre mineirum new species, from the Atlantic forest domain is described here. The cladistic analysis resulted in a single tree: (O.caatinga (O.mineirum ((O.tucuruiense+O.rufoniger) (O.diamantinensis (O.bolivianum +O.dominguense))))). According to the area cladogram obtained, it is possible to draw the following conclusions: the origin of the Cerrado fauna is monophyletic; the occurrence of two sympatric species in Caatinga is due to different events; and the diversity of Oligoxystre in Serra do Espinhao (O. rufoniger, O. diamantinensis and O. mineirum) is probably the result of the contact of the typical fauna of each bioma (Cerrado, Caatinga and Atlantic Forest). © 2011 The American Arachnological Society.

Clavate trichobothria are present on tarsi of all Theraphosidae and some Barychelidae spiders. They are also here reported on the tibiae of some theraphosids. A comparative analysis of their occurrence is presented. Representatives of all subfamilies of Barychelidae and Theraphosidae were studied. The following morphological patterns were recognized: filiform, thickened, and clavate. The surface of these trichobothria can be plumose or non-plumose. Five patterns in the disposition of clavate trichobothria on tarsi, were recognized: 1-two parallel rows; 2-two diverging rows; 3-one narrow, long median row; 4-one wide central row, intermixed with short covering setae; 5-a short row, restricted to the distal half of the tarsus. The disposition of trichobothria on tibiae did not differ among the taxa examined, except for those on lateral surfaces, where they can form a row or be grouped. Some patterns of morphology and distribution can be used as diagnoses of subfamilies and genera (e.g., Aviculariinae, Ischnocolus, Heterothele). The significance of such patterns in systematics is discussed and the usage in phylogeny is proposed. Copyright © 2012 Magnolia Press.
