. Phoretic relationships often bring large advantages to epibionts. By attaching themselves to mobile hosts, epibionts are able to: expand their ranges without spending energy, reduce their risk of being predated, and increase their probability of finding food. We assessed the phoretic relationship between the siluriform fish Ancistrusmultispinis (Regan, 1912) and the chironomid larva Ichthyocladius sp. in three streams of the Atlantic forest in southeastern Brazil. We evaluated changes in epibiont distribution throughout the body regions of the host and among three different aquatic systems. We had predicted that certain body regions are more prone to support epibiont attachment, and that epibiont prevalence increases with increased host size and quality of the aquatic system. Three streams (Santana, São Pedro and D’Ouro), tributaries of the Guandu River, were sampled during 2010 and 2011. A total of 102 specimens of A.multispinis were collected and analyzed. Epibionts were found in fourteen of fifteen body regions of the host. Observation from scanning electron microscopy revealed that Chironomidae larvae fix themselves to the spicules through the anal prolegs, not at the skin, as previously reported. The amount of epibionts (degree of infestation) was significantly correlated with fish size in the Santana Stream (r = 0.6, p < 0.01), and São Pedro Stream (r = 0.56, p < 0.01), but not in the D’Ouro Stream, the most altered of the three. The presence of epibionts on the body of the fish is directly correlated with the availability of spicules on the fish’s body, the largest numbers of infestations being found in structures associated with swimming (caudal and pectoral fins), since the swimming movement can create favorable conditions (e.g., suspension of organic particles, increasing oxygenation) for the epibiont.

<p>Aquatic oligochaetes can be found associated with different types of substrates; including bryophytes (mosses and liverworts) adhered to stones in lotic ecosystems. However, little information is available on the association between oligochaetes and bryophytes in tropical region. Therefore, the aims of this study were: to investigate whether the assemblages of oligochaetes respond to variation in the biomass of bryophytes and quantity of particulate organic matter (POM) present on these plants; verify differences in the composition of oligochaetes in streams flowing through areas with two phytophysiognomies (rocky field and seasonal semideciduous forest). The samples were collected from five first-order streams in the southeast of the state of Minas Gerais. Six samples of bryophytes adhered to stones were obtained from each stream. A total of 1586 oligochaetes were collected and 11 taxa were identified, belonging to the families Naididae and Enchytraeidae. The most abundant taxa were <em>Bothrioneurum</em> (37.95%) and Enchytraeidae (33.01%). A positive relation was observed between oligochaete abundance and POM in two streams (Ibitipoca I and Ibitipoca III) and a positive relation was found between oligochaete abundance and bryophyte biomass in one stream (Ibitipoca I). The composition of the fauna varied within and between the phytophysiognomies studied. The results show that the oligochaetes find favorable conditions to establish themselves in bryophytes, evidencing the ecological importance of these plants as habitat for invertebrates.</p>

In Vivo Mrs

In vivo MR spectroscopy (MRS) requires some kind of volume selection method to be able to measure the signal from a selected part of the body. To be able to interpret the spectra correctly, the quality of the volume selection must be investigated for each new MRS application using phantom measurements. A new phantom, especially suitable for precision measurements of the volume selection performance, is presented. It contains a small, remotely controlled signal source placed inside a larger vessel. This principle can be applied to various body regions, coil types and nuclei. The measurement conditions are close to the clinical situation. The phantom does not have to be repositioned during a signal profile measurement and the signal contribution from each point along the profile is determined regarding sign and amplitude.

Following behavior is a widespread feeding tactic among marine fishes, but remains poorly documented for freshwater fishes. The present study describes such association between two freshwater species: the minute armored catfish Parotocinclus maculicauda and the South American darter Characidium sp. During underwater observations in an Atlantic Forest stream, we recorded Characidium sp. closely following P. maculicauda (<5cm), catching the particles dislodged by this catfish's grazing activity. The following behavior displayed by the darter is considered opportunistic and possibly favors the capture of preys associated to the periphyton. This study is one of the few records of nuclear-follower feeding association between freshwater fishes and the first one in Atlantic Forest streams.

Sensory abnormalities such as numbness, paresthesias, and altered sensations of pain or temperature are common in MS. Using phenomenologic methodology, patient interviews were conducted to assess the occurrence of sensory abnormalities termed “macrosomatic illusions” in MS. These were defined as sensations of “largeness” accompanied by banding and/or tightness in specific body regions. These sensations were reported by 72 MS patients with mean disease duration of 4.7 years and mean EDSS score of 2.9. The phenomena usually affected more than one site: lower extremity (58 reports), torso (36 reports), upper extremity (26 reports), face (9 reports), and entire side of the body (4 reports). The sensations were variously described as “toes are like sausages,” “feels like I'm wearing clown shoes,” “like I have a tight corset on,” or “fingers feel swollen.” In five of seven patients for whom cervical MRI was available at the time of symptoms, lesions were identified in the spinal cord that correlated anatomically with the macrosomatic illusions. Longitudinal prospective studies are warranted to further characterize the prevalence and cause of these phenomena, their impact on disability and quality of life, and association with spinal cord disease.

The military policeman's work activity can lead to musculoskeletal overload, due to long working hours, standing for many hours and the use of heavy equipment such as the ballistic vest, which can cause discomfort, fatigue and musculoskeletal pain, predisposing these professionals to pain. That compromise your health and quality of life. This study aimed to evaluate the perception of musculoskeletal pain of military police, identifying the presence of painful points and establishing relationships between the points found and their working conditions. Fifty-five military police officers of both sexes, with more than five years of service to the institution, who belonged to the 15th Battalion of the city of Patos de Minas-MG, participated in the study. The sociodemographic and health questionnaire was applied and, subsequently, the “Body Pain Map”. All police officers had pain in some region of the body after the workday. Associations between the body regions with pain, the use of the ballistic vest, work vehicle and length of service, showed involvement mainly in the lower back region. Given the results presented, there is a prevalence of pain in the lower back followed by pain in the thoracic region. All participants were wearing the ballistic vest, a fact that influenced the presence of the painful points presented. Therefore, studies are important in order to detect health risk factors for these workers, in order to propose strategies that improve their quality of life.

Abstract There are few studies on the diet of Common Vampire Bat (Desmodus rotundus), despite its wide geographic distribution. The species is considered exclusively hematophagous, and medium and large-sized mammals are their main prey. In this study we report evidences of Common Vampire Bat feeding on Lowland Tapir (Tapirus terrestris) in a protected area located in the north of the state of Espírito Santo, southeastern Brazil, from camera trap records. The bat tried to access the Lowland Tapir by the posterior dorsolateral side of the body, and used the mean stratum of the vegetation as a point of support and observation between the consecutive offensives on the prey. In the same reserve, there were also two events of bat offensives on domesticated ox (Bos sp.). But in these cases the attacks occurred from the scapular region of the prey. The record here reported represents the first documented attack of Desmodus rotundus on Tapirus terrestris in the Brazilian Atlantic Forest and one of the first records in the South America as a whole. Previous records were in the Pantanal (Brazil) and in the Amazon rainforest (Ecuador). The feeding on wild and domestic prey by Desmodus rotundus in the same locality may favor the transmission of rabies to populations of wild mammals, as well as to domestic animals, and may represent an economic and public health issue with negative effects also for wildlife.

The Impact

Introduction. Occupational chronic obstructive pulmonary disease (COPD) is one of the leading nosological forms of occupational respiratory disease. Numerous studies have shown high effectiveness of the combination of indacaterol/glycopyrronium (Ultibro®breezhaler®) on the impact on clinical and functional indicators in the treatment of COPD in General practice.The aim of the investigation the case of occupational COPD with the analysis of the dynamics of functional indicators, tolerance to physical load and evaluation of the quality of life of workers engaged in aluminum production by using combination of indacaterol/glycopyrronium.Materials and methods. The random sampling method included 20 men, workers of aluminum production, with the established diagnosis of professional COPD at the age of 40 to 60 years. The survey was conducted (Borg scale, medical Research Council scale (mMRC) and COPD Assessment Test (CAT). Functional methods of studies were conducted: spirometry, body plethysmography, electrocardiography (ECG) and the six-minute stepper test (6-MST).Results. Against the background of 8 weeks of therapy, the volume of forced exhalation for 1 minute (FEV1) increased by 14.7% and amounted to 67.90% of the due values, the forced vital capacity of the lungs (FVC) increased by 11.3% and amounted to 76.95% of the due. According to the body plethysmography (BPG) is set to decrease in residual lung volume on average by 13.4% and static hyperinflation, confirmed by the decrease in functional residual volume (FRV) of 18.8%. During the study period increased physical activity of patients. The average difference between the distance traveled in the six-minute step test before and after treatment was 58.8 m. The analysis of personal data showed that the quality of life of patients improved, the total score in the questionnaire CAT at the beginning of the study was 16.9 points, and after 8 weeks decreased by 63% and amounted to 10.7 points.Conclusions: The Results indicate a positive effect of combination therapy with indacaterol/glycopyrronium on the course and progression of occupational COPD.

The main focus of this research is on the self-concept and pedagogical competence of the teacher and its influence on the quality of the learning process both partially and double. The research method used is a survey method in which the authors go directly to the empirical level by distributing questionnaires to 47 teachers. The processing and analysis techniques used are linear and multiple regression. The results of the study show that: (1) There is a positive and significant influence of the teacher's self-concept on the quality of the learning process (2) There is a positive and significant influence on the teacher's pedagogical competence on the quality of the learning process. (3) There is a positive and significant effect of self-concept and pedagogical competence of teachers together on the quality of the learning process. Therefore, the authors suggest: (1) So that the teacher improves health and appearance because the results of the study show that the weakness of the teacher's self-concept is in the appearance and significance of the body. So that the teacher needs to be given enlightenment related to how to maintain health and fitness through the implementation of joint gymnastics or conducting group discussions related to the dirt to maintain a prime body. (2) To face future competition and improve the quality of education it is deemed necessary to further increase the pedagogical competence of teachers, especially those related to planning and evaluation of learning.
