Abstract: the hyperhydricity, formerly called vitrification, is considered a physiological, biochemistry and morfologic disorder due to abnormal accumulation of water inside the cells and tissues. plants grown in vitro are undoubtedly under continuous stress condition which results in metabolic changes characteristic of oxidative stress. anatomically plants or shoots affected often become swollen, with pale green, translucent sheets, glass-like, low relative number of cells / cell area and hipolignification. physiological changes occur in major metabolic pathways including photosynthesis, respiration and transpiration resulting in reduced efficiency of these metabolic pathways. morphological, physiological and biochemical disorders are triggered by physical factors related to the environment of cultivation vessels and consistency of the culture medium or by chemical factors such as culture medium components, especially the growth regulators in high concentrations. the hyperhydricity occurs at various levels of severity, reaching result in irreversible loss of morphogenic capacity and the establishment of a state of neoplastic cells, however, in most cases hyperhydricity is considered reversible. this review focuses on the current knowledge about the phenomenon of hyperhydricity addressing morphological, physiological, biochemical, and reversibility of the process.

Background: The root canal length (RCL) estimates is an essential step for total endodontic therapy procedures. The aim of this study was to measure the RCL in a sample of extracted primary anterior teeth and compare the data obtained with the literature for educational and clinical purposes. Materials and methods: Seventy extracted primary anterior upper and lower teeth were selected according to the following inclusion criteria: absence of root resorption and/or internal root canal anatomy complications, and no previous root canal manipulation. The teeth were assigned to six groups: upper central incisors (UCI; n = 15), upper lateral incisors (ULI; n = 13), upper canines (UC; n = 20), lower central incisors (LCI; n = 6), lower lateral incisors (LLI; n = 3), and lower canines (LC; n = 13). RCL was measured by the direct method after insertion of a #15 K-file with a silicone stopper in the root canal until the root apex and measuring with a millimetre rule. Results: Mean RCL values (mm)?obtained were UCI = 14.33 ± 1.69; ULI =

Health (Health) , 2013, DOI: 10.4236/health.2013.56133

BACKGROUND: It is well established that the human aging process is associated with a significant decline in neuromuscular function and performance. Twin studies demonstrate that genetic factors partially explain the inter-individual variation of fat-free mass (FFM) and muscle strength. PURPOSE: To examine the association between the polymorphism of the gene IGF-2 with phenotypes strength and muscle mass of elderly women pre and post resistance training. METHODS: 76 elderly women participated in this analysis. These volunteers, who should be sedentary for at least 6 months before the study, were assigned four groups in relation to allele GAGG, AA, GAAA and GG. The first analysis compared 60 elderly women with GG and GA allele (GAGG) versus 16 elderly women with AA allele. The second analysis compared 54 elderly women with GA and AA (GAAA) versus 22 elderly women GG allele. The Body mass index, fat free mass, fat mass and Isokinetic Muscle Peak Torque were measured. All volunteers were participating in the Resistance Training program. The DNA was extracted from peripheral venous blood leukocytes using a salting out protocol. The primer for IGF-II gene exon 9 was 5’-GTCCCTGAACCAGCAAAGAG-3’ 0.5 μM (0.625 μl) Primer R-5’-TGATGGAAAAGGGAGTGAGG-3’ 0.5 μM (0.625 μl), Taq DNA Polimerase enzime 0.5 U (0.1 μl), água milli-Q (3.8 μl) 5 hg de DNA (3 μl). PCR amplification was performed in a programmable thermal cycler GeneAmp? PCR System 9700. RESULTS: The results of the first analysis GAGG × AA versus the group AA showed the relative increase in knee extensor peak torque relative and also in the fat-free mass and showed a decrease in the fat mass percentage in the GAGG group. The second analysis considered the group GAAA versus group GG showed decreases in the fat-free mass percentage in the GAAA group, also showed the relative increase in the fat-free mass in the GG group and decrease in the fat mass percentage in the GG group. CONCLUSIONS: The results of this study

Abstract: this report describes the reasons of the suicidal behavior in adolescents, taking in this anthropologic analysis, the impact in the familiar and social context. the study was conducted during the period of march to august, 2005 using a qualitative approach and ethnography as methods. the participants of this study were 12 teenagers, assisted in an emergency hospital in fortaleza, ceará state, brazil, for suicide attempt using any kind of mechanisms. as shown in the experiment's result, the main reason of the attempts was a broken heart, this as a reason of dating someone and others love relationship established between two persons. not only broken heart was mentioned, there were also cases of problems with family bonds, the affection and the lack of attention to the individual adolescent. in this context, the inability of the health professional was very clear. under the presented circumstances, the professional must come up with a new praxis approach. the suicide is a real fact present at the teenagers' life and it is necessary to redirect the brazilian unified health system′s philosophy and operational principles of the way health professionals cope with this demanding the society to embrace the politics that cares for the human being life and wellness.
Performance of Cooperative Eigenvalue Spectrum Sensing with a Realistic Receiver Model under Impulsive Noise

Journal of Sensor and Actuator Networks , 2013, DOI: 10.3390/jsan2010046
Abstract: In this paper we present a unified comparison of the performance of four detection techniques for centralized data-fusion cooperative spectrum sensing in cognitive radio networks under impulsive noise, namely, the eigenvalue-based generalized likelihood ratio test (GLRT), the maximum-minimum eigenvalue detection (MMED), the maximum eigenvalue detection (MED), and the energy detection (ED). We consider two system models: an implementation-oriented model that includes the most relevant signal processing tasks realized by a real cognitive radio receiver, and the theoretical model conventionally adopted in the literature. We show that under the implementation-oriented model, GLRT and MMED are quite robust under impulsive noise, whereas the performance of MED and ED is drastically degraded. We also show that performance under the conventional model can be too pessimistic if impulsive noise is present, whereas it can be too optimistic in the absence of this impairment. We also discuss the fact that impulsive noise is not such a severe problem when we take into account the more realistic implementation-oriented model.
