title: Extraction of hydrocolloids from Pereskia Aculeata Miller: reuse of process residue as activated carbon for the pigment-removal phase

description: Abstract Hydrocolloids of Pereskia aculeata Miller (OPNH) are potential ingredients in food industry as emulsifiers and stabilizers. The extraction process of OPNH requires the removal of pigments with activated carbon. Because this step is critical to the quality of the ingredient and has an impact on costs, a new activated carbon has been developed with residues from the same process. Residues activated with NaOH and H3PO4 (300 °C, 1 h) were subjected to batch adsorption tests in model solutions of malachite green (MG), carbohydrate and protein. Residue treated with 85% H3PO4 (OPNAC) had higher productivity and MG adsorption capacity, displaying a predominantly microporous surface (MEV/BET) with chemical activation confirmed by TG/FTIR. OPNAC showed higher MG and protein adsorption capacity than the commercial activated carbon (CAC) did. Results for MG-adsorption capacity by OPNAC did not show significant differences in the presence of protein and carbohydrate, presenting the higher affinity of the adsorbent for the dye. Adsorption isotherms showed OPNAC to be more favorable to MG adsorption than CAC, and to have a good fit to Langmuir-Freundlich model. OPNAC made it possible to reduce costs and allowed the sustainability of the process, leading to increased efficiency in selective pigment removal compared with CAC.

title: Effect of fertigation with potassium and nitrogen on gas exchange and biomass accumulation in eggplant1

description: ABSTRACT Adequate crop fertilization is one of the challenges for agriculture. Measuring gas exchange and biomass accumulation may be used to adjust crop management. The effect of fertigation with potassium (0 kg ha-1, 54 kg ha-1, 108 kg ha-1 and 216 kg ha-1) and nitrogen (0 kg ha-1, 67 kg ha-1, 134 kg ha-1 and 268 kg ha-1) on gas exchange and biomass accumulation in eggplant was assessed under greenhouse conditions. The net photosynthesis, stomatal conductance, transpiration, internal CO2 concentration, instantaneous carboxylation efficiency, water-use efficiency and total dry weight were evaluated. With the exception of K for water-use efficiency and N for internal CO2 concentration, all the other gas exchange parameters were significantly affected by the K and N doses. There was an interaction between N and K doses for net photosynthesis, stomatal conductance, transpiration and instantaneous carboxylation efficiency. The highest values for net photosynthesis, stomatal conductance, transpiration rate, carboxylation instantaneous efficiency and total dry weight were found in the range of 125-185 kg ha-1 of K and 215-268 kg ha-1 of N.

title: Individualized guidance and telephone monitoring in a self-supervised home-based physiotherapeutic program in Parkinson

description: Abstract Introduction: Home therapeutic exercises have been a target of interest in the treatment of the Parkinson's disease (PD). The way that the physical therapist guides and monitors these exercises can impact the success of therapy. Objective: To evaluate the effects of individualized orientation and monitoring by telephone in a self-supervised home therapeutic exercise program on signs and symptoms of PD and quality of life (QoL). Methods: Single-blind randomized clinical trials with 28 people with PD (Hoehn and Yahr 1 to 3). Patients were randomized into two groups: experimental and control. The experimental group had a meeting with individualized guidance about physiotherapy exercises present in a manual, received the manual to guide their activities at home and obtained subsequent weekly monitoring by telephone. The control group received the usual cares by the service. Both were orientated to carry out exercises three times a week during 12 weeks. Was evaluated: (1) activities of daily living (ADL) and motor examination sections of the Unified Parkinson's Disease Rating Scale (UPDRS) and QoL by the Parkinson Disease Questionnaire 39 (PDQ-39). The analysis between groups was performed by the Mann-Whitney test and intragroup through the Wilcoxon (p &lt; 0.05). Results: Significant improvement in ADL (p= 0.001) and motor examination (p= 0.0008) of the UPDRS, PDQ-39 total (p = 0.027) and dimensions mobility (p = 0.027), emotional well-being (p= 0.021) and bodily discomfort (p = 0.027) in the experimental group compared to the control group. Conclusion: The individualized guidance and weekly monitoring by telephone in a self-supervised home therapeutic exercises program promoted positive effects on ADL, motor examination and QoL of people in early stages of PD.

title: Anionic diet on clinical, haematological and biochemical parameters of heifers with subclinical hypocalcemia prepartum

description: ABSTRACT This study's hypothesis is that cows receiving anionic diet for a longer period respond more quickly to decreased blood calcium. The aim was to evaluate the heifers’ clinical, hematological, and biochemical parameters, with subclinical hypocalcemia, subjected to different periods of anionic diet supply during antepartum. Nine heifers were induced to subclinical hypocalcemia during antepartum, sorted in 3 groups: G0 = no anionic diet before induction; G11= eleven days of anionic diet before induction; and G15 = fifteen days of anionic diet before induction. Examinations were held before and after induction and total and ionized calcium, magnesium and albumin were evaluated from days -2, 0, 1, 2 and 3, day 0 being the moment of induction; hematologic parameters were evaluated at days 0, 1, 2 and 3. G11 presented a higher total and ionized calcium concentration than G0 and higher total calcium concentration than G15 (P &lt; 0.01). Magnesium had its highest values at G15 when compared to the other two groups (P &lt; 0.01). G0 presented its highest values of monocytes and neutrophils rods (P&lt;0.01). The eleven days of anionic diet supply were enough to maintain calcium homeostasis and leukocyte response in heifers challenged to reduction in blood calcium.

title: Spinal cord compression caused by melanoma in brown coat horse

description: ABSTRACT This paper describes a case of malignant melanoma in brown coat horse, which had ataxia and proprioceptive deficits in hind limbs, progressing to permanent decubitus. The animal was euthanized and the final diagnosis was based on necropsy and histopathology. At necropsy different masses and / or nodules in skeletal muscle, bone, abdominal cavity, lungs, heart, spleen, liver, adrenal gland, lymph nodes, brain and cerebellum were found. Neurological clinical signs presented by the animal were justified by spinal cord compression caused by melanocytic mass invading the medullary canal of the flow segment of the thoracic spine (between 15th and 18th thoracic vertebrae). This is the first case report of melanoma leading to spinal cord compression in a non-gray horse. Thus, it is important to include this neoplasm in the differential diagnosis list of cutaneous and subcutaneous masses and / or nodules, and in suspected cases of spinal cord compression in horses of any coat.

title: Phytochemical characterization and bioactivity of ethanolic extracts on eggs of citrus blackfly

description: ABSTRACT: The main objectives of this study were to determine the content of secondary metabolites (carotenoids, flavonoids, phenolic compounds, and tannins) of Argemone mexicana L., Ipomoea carnea Jacq. subsp. Fistulosa (Martius ex Choisy), Amorimia rigida (A.Juss.) W. R. Anderson, Ricinus communis L. and Syzygium aromaticum (L.) Merr. & L. M. Perry using UV-VIS spectroscopy, and evaluating the bioactivity of the ethanolic extracts on citrus blackfly eggs (Aleurocanthus woglumi Ashby, 1915). Pera sweet orange leaves infested with citrus blackfly eggs were treated by immersion in 0.5, 1.0, 5.0, and 10%; each replicate consisted of 30 eggs. The experimental design was completely randomized, with seven treatments and four replications. Three immersions of leaves with eggs were performed, and the mortality was evaluated seven days after the procedure. Leaves were placed in Petri dishes and kept in incubators [25±1°C; relative humidity (RH) 60±5% and 12 hours]. S. aromaticum peduncle presented high content of tannins and phenolic compounds, while R. communis leaves showed high content of phenolic compounds. The commercial product Bioneem© caused egg infeasibility greater than 85% at all concentrations. Treatments (10%) that caused the greatest egg mortality were Bioneem© (94.74%), R. communis extract (81.58%), and the extract of S. aromaticum peduncle (80.57%).

title: Breeding biology and conservation of hawk-eagles (Spizaetus spp.) (Aves, Accipitridae) in southern Atlantic Forest, Brazil

description: ABSTRACT Neotropical hawk-eagles (Spizaetus spp.) are large forest raptors, having low population densities and high sensitivity to human disturbance. The three species of Brazil’s Atlantic forest (S. ornatus, S. melanoleucus, S. tyrannus) are threatened and little is known of many aspects of their biology, such habitat requirements, nesting behavior, and food habitats. Here I present data about the breeding biology, diet and behavior of the Ornate Hawk-Eagle (S. ornatus; OHE) and the Black-and-white Hawk-Eagle (S. melanoleucus; BWHW), and estimations of distribution - extent of occurrence (EOO) - and population sizes for the three hawk-eagles of the southern Atlantic Forest. I compiled data from nine years of field studies done in Rio Grande do Sul and Santa Catarina combined with data from the literature (n = 191 records). I calculated the total amount of forest available for each species by GIS analyses and estimated population sizes based on species density data from the literature. The EOO was 123,551 km² for BWHE, 92,512 km² for OHE, and 67,824 km² for Black Hawk-Eagle (S. tyrannus; BHE). All species experienced more than 30% shrinkage in their historical distribution (before the year 2000). Forest remnants comprise 32% of BHE’s EOO and around 20% for other hawk-eagle species. Population sizes estimated for the southern region were 869 pairs for BHE (1,684 individuals), 1,532 pairs for BWHE (2,849 individuals), and 2,020 pairs for OHE (1,192 individuals). Population size estimates based only on forest patches larger than 10 km² were 542 pairs for BHE (RS = 48 pairs; SC = 494 pairs), 818 pairs for BWHE (RS = 67 pairs; SC = 751 pairs), and 1,178 pairs for OHE (RS = 67 pairs; SC = 1,111 pairs). I recorded displays and copulation of BWHE in July; the nest was built in an inaccessible, emergent tree in the hillside of a valley. Two nests of OHE were found in emergent trees (20 m and 30 m height) measured 138 x 115 x 45 cm and 132 x 100 x 100 cm; one egg was found (64.5 x 51.1 mm). Spizaetus seems to have very variable breeding cycles and begin breeding in the austral winter. I estimated egg laying occurs from July to September with fledging happening 3-4 months later. Diet of OHE consisted mostly of birds (90%) but also some mammals. Individuals of Spizaetus require large, unbroken forest areas to live, and my data reinforce the critical situation of hawk-eagles in southern Atlantic forest. All three species have lost habitat and their distributions have shrunk over the past decades. The estimated population sizes suggest concern and a need for conservation actions. Conservation of large raptors in the Atlantic Forest is not a simple task, requiring the need to preserve and limit the disturbance of remaining forests, establish connectivity among fragments and reduce direct threats to raptors (e.g., persecution). We also need to better understand the ecological requirements of hawk-eagles and establish public policies to protect both species and their habitats.
