title: Effect of biofertilizer obtained by anaerobic digestion of cassava effluent on the development of crambe plants

description: ABSTRACT This study aimed to evaluate the effect of applying increasing doses of biofertilizer obtained by the anaerobic digestion of cassava effluent on the development of crambe plants. The experiment was conducted in a protected environment at the Federal University of Paraná (UFPR), Palotina Sector, between April and August 2015. A completely randomized design was used, and five different treatments with the following doses were applied in five replicates: 0, 40, 80, 120, and 160 kg ha-1 of K2O. The following parameters related to plant development were evaluated: final height, stem diameter, number of branches, dry shoot and root biomass, mass of the grains, and oil content. The 160 kg K2O ha-1 dose was found to have the best influence on the plant development, because all the measured parameters reached their highest values at this dose, except for oil content, which attained the highest percentage in the case of the control treatment (0 kg ha-1 of K2O). This study proved that the biofertilizer obtained by anaerobic digestion of cassava effluent can be used as an alternative to regular fertilizers in cultivating crambe.

title: Medical waste in mobile prehospital care

description: ABSTRACT Objective: the objective of this study is to identify how Medical Waste (MW) is managed in Mobile Prehospital Care (MPC) services in the state of São Paulo as well as characterize and quantify this waste. Method: exploratory and descriptive field study with data collection based on the methodology proposed by the Pan American Health Organization (PAHO), which was conducted over eight consecutive days to identify the production and characteristics of generated waste. Results: it was found that the MW management of the MPC is not yet in line with the requirements of RDC 306/04, which could affect the occupational safety of workers, patients, the community, and the environment. Conclusion: it is recommended for the health managers to focus on this issue. The lack of studies with regard to MPC also indicates the need for further studies on the waste management.

title: Brazilian clinical engineering regulations: health equipment management and conditions for professional exercise

description: Abstract Introduction In Brazil, professionals, scientific community, and members of regulatory bodies have not yet achieved a consensus regarding who can legally perform the professional duties of a clinical engineer. We aim at clarifying this aspect, based on a detailed analysis of the pertinent regulations. Methods We acted on three fronts: (i) reviewing the current legislation regarding the clinical engineering exercise; (ii) visiting hospitals and working as trainee to understand how this exercise is implemented on Brazil’s Federal District; (iii) one of the authors participated in virtual discussion groups of clinical engineering professionals, monitoring collective understanding of regulations, checking consistency of proper knowledge, and acting as an active opinion leader in the subject among peers. Results We try to make a formal definition of clinical engineer and indicate their characteristic activities. We propose a synthesis of the regulation regarding healthcare products’ integrity protection and health technology management, identifying the engineering activities necessary to achieve those legal requirements. We analyze the legal constraints and conditions to exert engineering, indicating the necessary professionals’ attributions and the way to obtain them. Finally, we provide a brief analysis of the technical requirements presented by the Brazilian Consumer Protection Code and of the 15.943 Brazilian Standard (NBR). Discussion We conclude that, despite the lack of consensus about the Clinical Engineering activity, there exists in Brazil a Clinical Engineering regulation, but it is spread in complex laws and normative resolutions, defining compulsory responsibilities and attributions, as well as conditions and prerequisites for role performance.

title: Correction equations to estimate body fat with plicometer WCS dual hand

description: ABSTRACT Introduction This study aimed to propose regression equations for the correction of fat percentage values obtained with the WCS Dual Hand skinfold caliper, using the Lange skinfold caliper as a reference. Methods This study evaluated 112 undergraduate students from the Physical Education and Physical Therapy programs of the Faculdade Dom Bosco, located in Curitiba, Paraná, Brazil. Of these, 58 women were 24.9±5.8 years old and 54 men were 27.6±7.9 years old. The evaluation comprised the following measurements: height, body mass, and nine skin folds with WCS Dual Hand and Lange skinfold calipers used in biceps, triceps, subscapular, suprailiac, pectoral, average axillary, medial thigh, abdominal, and calf measurements. Results Through the simple linear regression analysis, eight equations were generated to correct the relative body fat obtained with equations commonly used in Brazil. For these correction equations, R2 was between 0.830 and 0.961 and p-value was 0.000 for all measurements. Conclusion These results indicate the use of equations for the correction of estimated values of relative body fat measured with the WCS Dual Hand skinfold caliper, whenever the Lange skinfold caliper is not available, in order to minimize the difference between them.

title: Elastic modulus of PVDF with bentonite or LiNbO3 using deformation energy

description: Abstract Polyvinylidene fluoride (PVDF) is valued for its properties of transparency to light, lightness, flexibility, mechanical strength, chemical stability, ease of processing, and low-cost production. Ceramics have low mechanical strength and poor processability, but have excellent piezo- and pyroelectric characteristics. The deficiencies of ceramics can be minimized by combining them with polymers. Accordingly, PVDF samples with different percentages of bentonite or LiNbO3 were used to obtain composites via “casting,” and the modulus of elasticity (E) of the composites was studied using a specially designed system. The method used to obtain E took into account the strain energy and the strength of the materials. Based on the results, E decreased with an increased percentage of bentonite and, in the case of LiNbO3, for the percentages of 30% and 35% increases.

title: Improving Natural Biopolymeric Membranes Based on Chitosan and Collagen for Biomedical Applications Introducing Silver

description: The aim of this study was to obtain new films based on collagen-chitosan with and without silver for biomedical applications. Membranes with a thin transparent elastic structure were obtained and after immersion in silver nitrate new membranes with silver have been elaborated and their physicochemical properties were assessed using infrared spectroscopy as well as contact angle determinations, and sorption properties. The water absorption has permitted the evaluation of the diffusion coefficient for modified collagen membranes and the values were comparable with diffusion coefficient specific for human cornea. Adsorption and desorption studies of silver ions were investigated based on the concentration of the silver solution. This concentration was determined by an inductively coupled plasma spectrometer. Antimicrobial investigations performed on Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria and hemolytic properties assays have been evaluated measuring optical density. The enhancement of antibacterial activity of membranes with silver content was emphasized.

title: Study of the protective effect of dexamethasone on cisplatin-induced ototoxicity in rats

description: Abstract Purpose: To evaluate the ability of dexamethasone to protect against cisplatin (CDDP)-induced ototoxicity. Methods: Male Wistar rats were divided into the following three groups: 1) Control (C): 6 animals received intraperitoneal (IP) saline solution, 8 ml/kg/day for four days; 2) C + CDDP: 11 animals received 8 ml/kg/day of IP saline and, 90 min after saline administration, 8 mg/kg/day of IP CDDP for four days; and 3) DEXA15 + CDDP: 11 animals received IP dexamethasone 15 mg/kg/day and, 90 min after dexamethasone administration, received 8 mg/kg/day of IP CDDP for four days. Results: It was found that dexamethasone did not protect against weight loss in CDDP-exposed animals. The mortality rate was comparable with that previously reported in the literature. The auditory threshold of animals in the DEXA15 + CDDP group was not significantly altered after exposure to CDDP. The stria vascularis of animals in the DEXA15 + CDDP group was partially preserved after CDDP exposure. Conclusions: Dexamethasone at the dose of 15 mg/kg/day partially protected against CDDP-induced ototoxicity, based on functional evaluation by brainstem evoked response audiontry (BERA) and morphological evaluation by optical microscopy. However, dexamethasone did not protect against systemic toxicity.

title: Developing Fast and Facile Method for Speciation Analysis of Vanadium (V/IV) Ions with Calmagite Immobilization on Triacetyl Cellulose Membrane in Water Samples

description: An inexpensive and fast vanadium [(IV), (V)] speciation method was performed by using optical chemical sensor that incorporates lipophilized calmagite (Cal) with cetyl pyridinium chloride (CPC) as a suitable ligand on triacetylcellulose membrane in aqueous solutions prior to UV-Vis spectrometric determination. Absorbance decrease of the optode in pH 6 at 490 nm depended on the V(V) ion concentration. The V(IV) content was found after oxidation to V(V) at the mentioned conditions. Two aliquots of sample were used for speciative determination of V(V) and V(V) + V(IV) mixture. With the optimized proposed sensor V(V) and V(IV) can be assayed with detection limits of 0.002 and 0.003 nmol L−1, respectively. The optode was tested by analysing several mixtures containing different ratios of V(V) + V(IV) and was found to be highly reproducible. The validity of the method was checked via spiked water samples with total relative standard error less than 4%.
