title: Association between undercarboxylated osteocalcin, bone mineral density, and metabolic parameters in postmenopausal women

description: ABSTRACT Objective: Osteocalcin has been associated with several effects on energy and glucose metabolism. However, the physiological role of undercarboxylated osteocalcin (U-osc; the hormonally active isoform of osteocalcin) is still controversial. To correlate the serum levels of U-osc with bone mineral density (BMD) values and metabolic parameters in postmenopausal women. Subjects and methods: Cross-sectional study including 105 postmenopausal women (age 56.5 ± 6.1 years, body mass index [BMI] 28.2 ± 4.9 kg/m2) grouped based on the presence of three or less, four, or five criteria of metabolic syndrome according to the International Diabetes Federation (IDF). The subjects underwent dualenergy x-ray absorptiometry (DXA) for the assessment of body composition and BMD and blood tests for the measurement of U-osc and bone-specific alkaline phosphatase (BSAP) levels. Results: The mean U-osc level was 3.1 ± 3.4 ng/mL (median 2.3 ng/mL, range 0.0-18.4 ng/mL) and the mean BSAP level was 12.9 ± 4.0 ng/mL (median 12.1 ng/mL, range 73-24.4 ng/mL). There were no associations between U-osc and BSAP levels with serum metabolic parameters. Lower fasting glucose levels were observed in participants with increased values of U-osc/femoral BMD ratio (3.61 ± 4 ng/mL versus 10.2 ± 1.6 ng/mL, p = 0.036). When the participants were stratified into tertiles according to the U-osc/ femoral BMD and U-osc/lumbar BMD ratios, lower fasting glucose levels correlated with increased ratios (p = 0.029 and p = 0.042, respectively). Conclusion: Based on the ratio of U-osc to BMD, our study demonstrated an association between U-osc and glucose metabolism. However, no association was observed between U-osc and metabolic parameters.The U-osc/BMD ratio is an innovative way to correct the U-osc value for bone mass.

title: Influence of extreme hydrological events in the quality of water reservoirs in the semi-arid tropical region

description: ABSTRACT Inland water environments, such as natural and artificial lakes, are increasingly vulnerable to extreme events (heavy rains, severe drought). This study aims to evaluate if this events affect the water quality of tropical semi-arid springs. The results showed that the reservoirs presented significant changes in the limnological variables between the rainy season and severe drought periods. However, different behaviors were observed among reservoirs in the period of severe drought, which indicate that the responses of these environments to extreme events should take into account other factors such as the climate of the region, the size and depth of the reservoir.

title: Geophysical investigation of earth dam using the electrical tomography resistivity technique

description: Abstract Dams are structures that dam rivers and streams for a variety of purposes. These structures often need to be sturdy to withstand the force of the impoundment and the high values of accumulated water load. The constant maintenance of these structures is essential, since a possible accident can lead to damage of catastrophic proportions. This research presents an alternative cheap and quick application for investigating water seepage in earth dams, through the application of the DC resistivity geophysical method from the electrical resistivity tomography (ERT) technique in Wenner array. Three ERT lines were placed parallel to the longitudinal axis of a dam formed by clay soil from the decomposition of diabase. The data are presented in 2D and pseudo-3D geophysical images with electrical resistivity values modeled. Based on the physical principle of electrolytic conduction, that is, decrease in electrical resistance in materials or siliceous minerals in moisture conditions as compared to the material in the dry state, the results revealed low-resistivity zones restricted to some points, associated with water infiltration in the transverse direction of the dam. The absence of evidence as water upwelling on the front of the dam together with geophysical evidence indicate saturation restricted to some points and low probability at the present time, for installation of piping processes.

title: Profile and trend analysis of toxicological events in children attended by a University Hospital

description: Abstract Background Poisoning is an important public health problem with socioeconomic and health impact. Objective This study aimed to determine the profile and trend of toxicological events in children. Method Trend study conducted with children (children under 12 as defined by the Statute of Children and Adolescents) reported by the Toxicological Information Center (CIATox) of Londrina, from 2005 to 2014. The variables were collected through the CIATox-Londrina database. Trend analysis was performed using simple linear regression models. Results We identified 4,726 toxicological events in children, with a predominance of 1 to 3 years (59.2%). The majority (93.5%) was comprised of accidental cases, acute (99.8%) and with medication (34.6%) as toxicological agents. Approximately 88.1% of the patients did not require hospitalization, and the death rate was low (0.1%). There was a significant increase in the proportion of cases involving household products (R2 = 0.440; p = 0.037; β1=0.307) and chemicals (R2 = 0.456; p = 0.032; β1=0.345); and a significant reduction in accidents with rodenticides (R2 = 0.589; p = 0.010; β1=-0.246). Conclusion We observed a prevalence of children from 1 to 3 years old of age, with accidental and acute exposure, mainly involving medications. We highlight a significant increase in the proportion of cases involving household products and chemical products, and a significant reduction in cases with rodenticides.

title: Eugenia connection with issues bioethical: an integrative review

description: The objective of the study is analyzing the scientific productions that deal about binding- the eugenics with the bioethical issues. This is an integrative literature review. The data were collected in Lilacs and SciELO, through descriptors: eugenics, ethnicity and health, ethics and bioethics. For later analysis and synthesis of the synoptic articles a figure was used. It was found that eugenics violates human rights, contradicts with the principle of solidarity and endangers human diversity. It was concluded that there were articles addressing bioethical issues related to eugenics, thus, this study may contribute to the reflection on this articulation deficit.

title: OVULATION INDUCTION WITH VAGINAL SWAB IN DOMESTIC FEMALE CATS AND ITS EFFECTS ON UTERINE MORPHOLOGY

description: Abstract A neuroendocrine reflex attributed to the mechanical stimulation of sensory receptors during copulation induces ovulation in cats. This stimulation can be simulated with a vaginal swab, triggering pseudopregnancy. The efficiency of ovulation induction with swab was evaluated in order to establish a natural contraceptive treatment for domestic cats as well as to analyze the effect on uterus of the repeated use of this technique. At the first phase of the study, 12 animals were evaluated in three consecutive estrous cycles. In the first cycle (T1), vaginal swab stimulation was applied. In the second cycle (T2), a vasectomized male was used. In the third cycle (T3), ovulation was accompanied unstimulated (control). At the second phase of the study, 13 female cats were induced to successive pseudopregnancy states to check the effects on the uterus. Confirmation of ovulation in the two phases of the study was carried out by measuring progesterone serum levels. The vaginal swab stimulation showed a similar response to that obtained by natural mating (P&gt;0.05). Some cats showed mild uterine changes without pathological relevance. Thus, ovulation induction with swab is secure and without significant side effects.

title: Salivary and microbiological parameters of chronic periodontitis subjects with and without type 2 diabetes mellitus: a case-control study

description: Background: Several studies have investigated the differences in salivary parameters and microbial composition between diabetic and non-diabetic patients, however, specific differences are still not clear mainly due to the effects of confounder.Aim: The aim of this case-control study was to evaluate the salivary and microbial parameters of chronic periodontitis subjects with and without type 2 diabetes mellitus.Material and method: This case-control study included 60 chronic periodontitis subjects, 30 diabetics (case group) and 30 non-diabetics (control group), paired according to periodontitis severity, gender and age. Stimulated whole saliva was collected from all volunteers to measure the salivary pH and the salivary flow rate. Bacterial samples were collected with paper points from periodontal sites showing the deepest periodontal pocket depth associated with the highest clinical attachment loss. The frequency of A. actinomycetemcomitans, P. intermedia, P. gingivalis, T. forsythiaand C. rectuswas evaluated by PCR. Data was statistically analyzed by Student's t, Mann-Whitney and Chi-square (p&lt;0.05).Result: Diabetic subjects showed higher salivary glucose levels and lower stimulated flow rates in comparison to non-diabetic controls. P. gingivalisand T. forsythia were the most frequent pathogens (p&lt;0.05). Bacterial frequency did not differ between case and control groups.Conclusion: Diabetes status influenced salivary glucose levels and flow rate. Within the same severity of chronic periodontitis, diabetic subjects did not show higher frequency of periodontal pathogens in comparison to their paired controls.

title: NILE TILAPIA FED ENZYME COMPLEX ADDED AT DIFFERENT LEVELS AND PROCESSING STEPS

description: ABSTRACT Enzyme activity in solid-state fermentation complex added to diets before and after extrusion process and its influence on Nile tilapia (Oreochromis niloticus) performance were evaluated. The following enzymes were analyzed: b-glucosidase, pectinase, xylanase, endoglucanase, amylase, protease, and phytase. The fish were fed five experimental diets: a control diet (without enzyme), two test diets supplemented before extrusion (400 and 800 ppm SSF), and two test diets after extrusion or “on top” (400 and 800 ppm SSF). The experiment had a completely randomized design with four replicates and seven fish per tank. Average initial weight was 10.37 ± 0.95 g, and fish were fed four times a day to satiation for 56 days. The following performance parameters were evaluated: final weight, weight gain, feed conversion, survival, specific growth rate, and body composition. The results were compared using ANOVA and Tukey’s test at p&lt;0.05. All the enzymes showed partial or total losses of activity when subjected to the extrusion process, except phytase. No differences were observed for survival, water quality parameters, and body composition. On-top inclusion provided a better performance, which is observed through increases in final weight, weight gain, and feed conversion. As a result, 800 ppm of enzyme complex SSF should be added "on top", that is after extrusion, to improve tilapia performance and, consequently, contribute to the fish farming financial efficiency.

title: Operating yields of an aquatic weed harvester and a long-arm hydraulic excavator in aquatic macrophyte control in Piraquara II reservoir, southern Brazil

description: ABSTRACT Eutrophication of water bodies has caused environmental imbalance, changing population dynamics, as the excessive growth of aquatic macrophytes. The mechanical methods are the most used to control these communities. The aim of this study was to evaluate the operational yield of a harvesting boat and a long-arm hydraulic excavator (in group and individually) in the removal of floating aquatic weeds (and their Nt and Pt contents) in Piraquara II Reservoir, in Southern Brazil. The duration of each of the 100 operational cycles (including loading, transport and unloading of trucks), besides other activities were measured through timing. The hydraulic excavator presented right yields in the removal of weeds from the water body as compared to other studies reported in the literature. However, the adding of the harvesting boat led to an increase of productivity (about 115%). The average yield was 35.57 ± 0.27 m3/h or 284.67 m3/day. Applying area, mass and volume relations for the studied site, this is equivalent to 3273.7 m2/day (considering 11.5 m2/m3) or 142.28 humid tons/day (humid density of 0.5 ± 0.08; n = 30). Therefore, for similar situations, both equipment (mainly in a joint operation) are recommended to aquatic weed infestation control.
