The use of low level laser therapy in the treatment of temporomandibular joint disorders. Review of the literature

Introduction: The temporomandibular disorders (TMDs) have been identified as the most important cause of pain in the facial region. The low level laser therapy (LLLT) has demonstrated to have an analgesic, anti-inflammatory and biostimulating effects. The LLLT is a noninvasive, quick and safe, non-pharmaceutical intervention that may be beneficial for patients with TMDs. However the clinical efficiency of LLLT in the treatment of this kind of disorders is controversial. Objectives: Literature review in reference to the use of LLLT in the treatment of TMDs, considering the scientific evidence level of the published studies. Material and Methods: A MEDLINE and COCHRANE database search was made for articles. The keywords used were “temporomandibular disorders” and “low level laser therapy” or “phototherapy” and by means of the Boolean operator “AND”. The search provided a bank of 35 articles, and 16 relevant articles were selected to this review. These articles were critically analyzed and classified according to their level of scientific evidence. This analysis produced 3 literature review articles and 13 are clinical trials. The SORT criteria (Strength of Recommendation Taxonomy) was used to classify the articles. Results: Only one article presented an evidence level 1, twelve presented an evidence level 2, and three presented an evidence level 3. According to the principle of evidence-based dentistry, currently there is a scientific evidence level B in favor of using LLLT for treatment of TMDs. Discussion and conclusions: Publications on the use of LLLT for treatment of TMDs are limited making difficult to compare the different studies due to the great variability of the studied variables and the selected laser parameters. The great majority of the studies concluded that the results should be taken with caution due to the methodological limitations. Key words:Low level laser therapy; phototherapy; temporomandibular joint disorders.
Ranging in an Underwater Medium with Multiple Isogradient Sound Speed Profile Layers

In this paper, we analyze the problem of acoustic ranging between sensor nodes in an underwater environment. The underwater medium is assumed to be composed of multiple isogradient sound speed profile (SSP) layers where in each layer the sound speed is linearly related to the depth. Furthermore, each sensor node is able to measure its depth and can exchange this information with other nodes. Under these assumptions, we first show how the problem of underwater localization can be converted to the traditional range-based terrestrial localization problem when the depth information of the nodes is known a priori. Second, we relate the pair-wise time of flight (ToF) measurements between the nodes to their positions. Next, based on this relation, we propose a novel ranging algorithm for an underwater medium. The proposed ranging algorithm considers reflections from the seabed and sea surface. We will show that even without any reflections, the transmitted signal may travel through more than one path between two given nodes. The proposed algorithm analyzes them and selects the fastest one (first arrival path) based on the measured ToF and the nodes’ depth measurements. Finally, in order to evaluate the performance of the proposed algorithm we run several simulations and compare the results with other existing algorithms.
Distributed coloring in O~(⎷(log n)) bit rounds

We consider the well-known vertex coloring problem: given a graph G, find a coloring of the vertices so that no two neighbors in G have the same color. It is trivial to see that every graph of maximum degree Δ can be colored with Δ+1 colors, and distributed algorithms that find a (Δ+1)- coloring in a logarithmic number of communication rounds, with high probability, are known since more than a decade. This is in general the best possible if only a constant number of bits can be sent along every edge in each round. In fact, we show that for the n-node cycle the bit complexity of the coloring problem is Ω(log n). More precisely, if only one bit can be sent along each edge in a round, then every distributed coloring algorithm (i.e., algorithms in which every node has the same initial state and initially only knows its own edges) needs at least Ω(log n) rounds, with high probability, to color the cycle, for any finite number of colors. But what if the edges have orientations, i.e., the endpoints of an edge agree on its orientation (while bits may still flow in both directions)? Does this allow one to provide faster coloring algorithms? Interestingly, for the cycle in which all edges have the same orientation, we show that a simple randomized algorithm can achieve a 3-coloring with only O(√log n) rounds of bit transmissions, with high probability (w.h.p.). This result is tight because we also show that the bit complexity of coloring an oriented cycle is Ω(√log n), with high probability, no matter how many colors are allowed. The 3-coloring algorithm can be easily extended to provide a (Δ + 1)-coloring for all graphs of maximum degree Δ in O(√log n) rounds of bit transmissions, w.h. p., if Δ is a constant, the edges are oriented, and the graph does not contain an oriented cycle of length less than √log n. Using more complex algorithms, we show how to obtain an O(Δ)- coloring for arbitrary oriented graphs of maximum degree Δ using essentially O(logΔ + √log n) rounds of bit transmissions, w.h. p., provided that the graph does not contain an oriented cycle of length less than √log n.
Familial Mutations and the Thermodynamic Stability of the Recombinant Human Prion Protein*

Hereditary forms of human prion disease are linked to specific mutations in the PRNP gene. It has been postulated that these mutations may facilitate the pathogenic process by reducing the stability of the prion protein (PrP). To test this hypothesis, we characterized the recombinant variants of human PrP(90–231) containing point mutations corresponding to Gerstmann-Straussler-Scheinker disease (P102L), Creutzfeld-Jakob disease (E200K), and fatal familial insomnia (M129/D178N). The first two of these mutants could be recovered form from the periplasmic space of Escherichia coli in a soluble form, whereas the D178N variant aggregated into inclusion bodies. The secondary structure of the two soluble variants was essentially identical to that of the wild-type protein. The thermodynamic stability of these mutants was assessed by unfolding in guanidine hydrochloride and thermal denaturation. The stability properties of the P102L variant were indistinguishable from those of wild-type PrP, whereas the E200K mutation resulted in a very small destabilization of the protein. These data, together with the predictive analysis of other familial mutations, indicate that some hereditary forms of prion disease cannot be rationalized using the concept of mutation-induced thermodynamic destabilization of the cellular prion protein.
Does metoclopramide impair anastomotic healing of the left colon of rats?

PURPOSE To evaluate the effects of metoclopramide on the formation of adhesion and the healing of left colonic anastomoses in rats. METHODS Forty rats underwent sectioning of the left colon and end-to-end anastomosis and were divided into two groups of 20 animals for the administration of metoclopramide (experimental group - E) or saline solution (control group - C). Each group was divided into subgroups of 10 animals each to be killed on the third (E3 and C3) or seventh postoperative day (E7 and C7). Adhesion was assessed, and a colonic segment containing the anastomosis was removed for analysis of breaking strength and hydroxyproline concentration. RESULTS There were no deaths or dehiscence on the 3(rd) postoperative day. There was one death and one blocked anastomotic dehiscence in the E7 group. No significant differences between groups were found in the analysis of clinical outcome, intra-cavity adhesion, adhesion to the anastomosis or breaking strength on the 3(rd) and 7(th) postoperative day. Hydroxyproline concentration was higher in the control group on the 3(rd) (p=0.006) but not on the 7(th) postoperative day (p=0.241). CONCLUSION Metoclopramide did not have harmful effects on the healing of intestinal anastomoses in rats.
The sedative effects of low-dose medetomidine and butorphanol alone and in combination intravenously in dogs.

OBJECTIVE To evaluate the sedative effects of intravenous (IV) medetomidine (1 μg kg-1) and butorphanol (0.1 mg kg-1) alone and in combination in dogs. STUDY DESIGN Prospective, blinded, randomized clinical trial. ANIMALS Sixty healthy (American Society of Anesthesiologists I) dogs, aged 6.2 ± 3.2 years and body mass 26 ± 12.5 kg. METHODS Dogs were assigned to four groups: Group S (sodium chloride 0.9% IV), Group B (butorphanol IV), Group M (medetomidine IV) and Group MB (medetomidine and butorphanol IV). The same clinician assessed sedation before and 12 minutes after administration using a numerical scoring system in which 19 represented maximum sedation. Heart rate (HR), respiratory rate, pulse quality, capillary refill time and rectal temperature were recorded after each sedation score assessment. Sedation scores, sedation score difference (score after minus score before administration) and patient variables were compared using one-way anova for normally distributed variables and Kruskal-Wallis test for variables with skewed distributions and/or unequal variances. Where significance was found, further evaluation used Bonferroni multiple comparisons for pair-wise testing. RESULTS Breed, sex, neuter status, age and body mass did not differ between groups. Sedation scores before substance administration were similar between groups (p = 0.2). Sedation scores after sedation were significantly higher in Group MB (mean 9.5 ± SD 5.5) than in group S (2.5 ± 1.8) (p < 0.001), group M (3.1 ± 2.5) (p < 0.001) and group B (3.7 ± 2.0) (p = 0.003). Sedation score difference was significantly higher in Group MB [7 (0-13)] than in Group S [0 (-1 to 4)] (p < 0.001) and Group M [0 (0-6)] (p < 0.001). HR decreased significantly in Groups M and MB compared with Group S (p < 0.05). CONCLUSION AND CLINICAL RELEVANCE Low-dose medetomidine 1 μg kg-1 IV combined with butorphanol 0.1 mg kg-1 IV produced more sedation than medetomidine or butorphanol alone. HR was significantly decreased in both medetomidine groups.
Solution of a 20-Variable 3-SAT Problem on a DNA Computer

A 20-variable instance of the NP-complete three-satisfiability (3-SAT) problem was solved on a simple DNA computer. The unique answer was found after an exhaustive search of more than 1 million (220) possibilities. This computational problem may be the largest yet solved by nonelectronic means. Problems of this size appear to be beyond the normal range of unaided human computation.
Migration of Skilled Latin American Women to Switzerland and Their Struggle for Integration

Contemporary migration to the North is increasingly a female phenomenon. The literature has interpreted the accompanying upsurge in binational marriages as reflecting the escape of unskilled women from poverty in the South. This paper argues that many female migrants are in fact highly skilled, and that their binational marriages are not motivated chiefly by economics but by reasons of love and gender representations. A differentiated view of female migrants and of marriage migration is expounded, as revealed by testimonies of skilled Latin American women in Switzerland. The methods of study include in-depth interviewing, participant observation and focus groups. An analysis of the situation of social integration of these women shows that the majority are either employed at a level well below their qualifications or are excluded from the job market. This process has its roots in the prevailing discourses in Swiss society, which have lead to social practices and immigration policies that effectively hinder the social integration of female immigrants. In reaction to these barriers, the immigrant women have created numerous action networks, which demonstrate their initiative and desire to participate in Swiss society. The conclusion is a paradox: whereas Latin America loses valuable human capital, Switzerland fails to take advantage of its gain in human capital.
Apolipoprotein C-I Polymorphism and Its Association with Serum Lipid Levels and Longevity in the Bama Population

This study aims to determine the association between the apolipoprotein C-I polymorphism and the longevity and genetic variants in ApoC-I that can influence the serum lipid levels in Bama. ApoC-I genotypes were determined by Taqman single nucleotide polymorphism (SNP) genotyping assays in 178 long-lived inhabitants (longevity group aged from 90 to 110 years), 147 healthy controls (Control 1 group aged from 40 to 79 years old) from Bama County, and 190 healthy controls (Control 2 group aged from 40 to 79 years old) from Nandan County without a family history of longevity. Statistical analysis was conducted using SPSS 16.0. All genotype distributions of rs584007 and rs4420638 were consistent with the Hardy–Weinberg equilibrium (p > 0.05). Significant differences were observed in the frequencies of the three genotypes (GG, AG, and AA) among the longevity and the two control groups (χ2 = 11.238, p = 0.024) for rs584007. No significant differences were observed in the frequencies of the three genotypes (GG, AG, and AA) among the longevity and the two control groups (χ2 = 4.587, p = 0.318) for rs4420638. The levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-c), and low-density lipoprotein-cholesterol (LDL-c) were not different among the three genotypes of rs584007 in the three groups. The levels of HDL-c for GG, AG, and AA were significantly different (the highest being in the longevity group), while the levels of TG for AA and AG genotypes (the lowest being in the longevity group) and the levels of LDL-c for AG were significantly different (p < 0.05) among the three groups for rs584007. The levels of TG and HDL-c were significantly different among the three rs4420638 genotypes in the longevity group. The levels of TC for GG, AG, and AA were significantly different in the Control 2 group, while the levels of TG and HDL-c for AA and AG genotypes were significantly different (p < 0.05) among the three groups for rs4420638. The level of HDL-c was highest in the longevity group for AA and AG genotypes, and the level of TG was highest in the Control 2 group for rs4420638. Serum lipid parameters were related to environmental factors, including age, gender, BMI, DBP, SBP, rs4420638, and rs584007. The ApoC-I polymorphism might be one of the genetic factors of longevity in Bama. The ApoC-I rs4420638 and rs584007 SNPs are associated with serum TG and HDL-c levels in the longevous population.
Bivalve taphonomy in tropical mixed siliciclastic-carbonate settings. I. Environmental variation in shell condition

Abstract Contrary to the geological stereotype of pure-carbonate reef platforms, approximately 50% of shallow shelf area in the Tropics is accumulating siliciclastic and mixed siliciclastic-carbonate sediments. Taphonomic characterization of these settings is thus essential for assessing variation among major facies types within the Tropics, as well as for eventual comparison with higher-latitude settings. Our grab samples and dredge samples of bivalve death assemblages from nine stations in five subtidal habitats in a large marine embayment of Caribbean Panama (Bocas del Toro) provide the first actualistic information on the taphonomic condition of shells in Recent tropical siliciclastic sediments. Focusing on unambiguous damage to bivalve shell interiors, we found that the quality of shell preservation in fine-grained siliciclastics is superb: commonly <10% of specimens are affected by encrustation, boring, edge-rounding, and fine-scale surface alteration via dissolution, microbioerosion, and maceration. Pure-carbonate and mixed siliciclastic-carbonate environments containing hard substrata (patch reefs, Halimeda gravelly sand, mud among patch reefs) contain higher numbers of more severely damaged shells (generally >25%) and also higher diversities of fossilizable encrusters and borers. Disarticulation and fragmentation are pervasive across all environments and are probably related to predation rather than to postmortem processes. As in other shallow subtidal study areas, the taxonomic compositions of death assemblages have not been homogenized by postmortem transport but show high spatial fidelity to the distribution of living species. Assemblages from the five sedimentary environments have distinct taphonomic signatures, but the strongest differences are between the two fine-grained, exclusively soft-sediment siliciclastic environments on the one hand and the three environments containing hard substrata on the other. Experimental tests for rates and agents of damage, still in progress, indicate that the most critical environmental variables are exhumation cycles and burial rate. Bivalve death assemblages from Bocas del Toro demonstrate that damage levels in tropical fine-grained siliciclastic environments are much lower than in closely associated reefs and algal sands, and suggest a less filtered record of biological information.
Etiology and incidence of zygomatic fracture: a retrospective study related to a series of 642 patients.

BACKGROUND AND OBJECTIVES The aim of this paper is to investigate epidemiological data (age, gender), sites, etiology and surgical approach of zygomatic fracture. MATERIALS AND METHODS A 9 years retrospective clinical and epidemiologic study evaluated 642 patients treated for zygomatic fracture. There were 569 men and 77 women. The age range was 2 to 86 years with 205 (31.9%) in the 21 to 30 years age group. A number of parameters, including age, gender, cause of injury, site of injury, treatment modalities were evaluated. RESULTS There were 552 (86%) zygoma fractures and 90 (14%) zygomatic arch fractures. The left zygoma was involved in 309 cases (56%); the right zygoma was involved in 243 cases (44%). Concerning the zygomatic arch, the left side was involved in 43 cases (48%) and the right side in 47 cases (52%). 7% of the patients were younger than 9 years old, about 70% between 10 and 39 years, and 18% between 40 and 59 years, while 4% were older than 60 years. Causes of zygoma fracture were traffic accidents in 151 (26%), assault in 117 (20%), accidental falls in 105 (19%), sports injuries in 56 (10%), home injuries in 45 (8%), work accidents in 34 (6%). Causes of zygomatic arch fractures 28 (29.1%) were assaults in 28 (29.1%), traffic accidents in 20 (21.5%), sports injuries in 14 (15.8%), accidental falls in 11 (14%), domestic accidents in 8 (8.8%) and work accidents in 4 (5%). The access to the fronto-zygomatic suture (74.6%) and the maxillary vestibular approaches (66.8%) were the commonest method of reduction of zygomatic fracture. About arch fractures, the Gillies temporal approach was the most used method of reduction (94.4%). CONCLUSIONS The findings, compared with similar studies reported in the literature, support the view that the highest prevalence is in young male patients and, concerning cause, traffic accidents and assault are the most frequent.
Adjustment of costly extra-group paternity according to inbreeding risk in a cooperative mammal

Lay Summary Female-banded mongooses risk their lives to mate with rivals during pack “warfare. ” Data from wild banded mongooses reveal that 18% of pups are fathered by males from rival packs. These pups are less likely to be inbred are heavier and have higher survival chances than their within-pack counterparts. However, their mothers risk a lot to mate with extra-pack males; aggressive encounters between packs account for 20% of pup deaths and 12% of adult deaths.
Correlation of Students’ Listening Comprehension Score With Students’ Learning Styles at Students of English Department at University of Muhammadiyah Gresik

Listening ability is an important component of language teaching and learning as it tends to improve faster than speaking ability and frequently influences skill development when learning anything new. Meanwhile, in order to accomplish excellent academic outcomes, students need to consider their learning styles and teachers need to consider various students’ learning style. This study aims to investigate the correlation between the listening abilities of learners and their learning styles. The participants were students of English education study program, faculty of teaching and educational sciences, Muhammadiyah University of Gresik, with 48 males and 52 female students participating. This study employed quantitative approaches using a questionnaire to assess students' learning styles, a test to assess students' listening comprehension scores, and an interview as a few sample about students’ perception. The data analyzed used SPSS Pearson's Correlation Coefficients and thematic analysis. The level of probability (p-value) significance (sig.2-tailed) resulted in . 003. Since, the p-value (.003) was less than . 05, Ha (alternative hypothesis) was accepted and Ho (null hypothesis) was rejected. As a result of the acceptance of the Ha (alternative hypothesis), researchers discovered there is a significant correlation connecting both visual and auditory learning styles and listening comprehension. The impact of this study to help students aware with their learning styles and teachers need to consider efficient learning activities with students’ various learning style.
To Decode the Interference or to Consider It as Noise

In this paper, the impact of noncoordinated interfering signals on a point to point communication is addressed. While the transmitter has no information about the other users' messages, the receiver has full knowledge of the codebooks of the interfering users and can potentially decode some part of the interference. A simple coding strategy is proposed for this channel. Assuming its own data is decoded successfully, the receiver partitions the set of interfering users into two disjoint subsets, namely the set of decodable users and the set of nondecodable users. Then the transmitter's rate is chosen such that the intended signal can be jointly decoded with the set of decodable users. It is proved that the proposed strategy achieves the capacity of the additive Gaussian channel with Gaussian interfering users. A polynomial time algorithm is proposed to compute the achievable rate of the scheme. This algorithm is based a subroutine which separates the set of interfering users into decodable and nondecodable users in polynomial time. The proposed scheme is also applied to the case of -user interference channel and some achievable points are characterized by successive maximization of users' rates.
