title: Arbuscular mycorrhizal fungi action on the quality of strawberry fruits

description: ABSTRACT The inoculation of arbuscular mycorrhizal fungi (AMF), increasing the rhizospheric influence, might provide higher levels of bioactive compounds. Thus, the objective was to evaluate the influence of the AMF inoculation on the physicochemical components of fruit’s quality in field. Strawberry fruits from cultivars Camarosa, Aromas, Camino Real, Monterey, Portola, San Andreas and Albion in 2016, and Camarosa, Camino Real, Monterey and Albion in 2017 were either inoculated or non-inoculated with AMF. The analyzed physicochemical components of fruit’s quality were ascorbic acid, titrated acidity, pH, soluble solids, soluble solids/titrated acidity ratio, phenolic compounds, anthocyanins, and firmness. The inoculation with AMF on strawberry plants in field improved the fruit’s physicochemical attributes, increasing pH, soluble solids content, soluble solids/titratable acidity ratio and phenolic compounds content in both cultivation years (2016-2017). The inoculation of AMF has improved the characteristics of post-harvest quality in strawberry fruits.

title: Elderly caregivers of the elderly: frailty, loneliness and depressive symptoms

description: ABSTRACT Objective: to investigate the association between frailty, loneliness and depressive symptoms of elderly caregivers. Method: a cross - sectional study carried out with 341 elderly caregivers enrolled in Family Health Units of a city in the countryside of São Paulo State. The interviews were domiciliary and included questionnaire for characterization of the caregiver, Fried’s frailty phenotype, family APGAR (family functionality), Geriatric Depression Scale (depressive symptoms) and item 3 of the Herth Hope Scale (loneliness). Logistic regression was used to analyze the association between depressive symptoms and solitude (independent variables), and frailty and pre-frailty (dependent variables). Results: there was an association between frailty, loneliness and depressive symptoms. Elderly caregivers had increased odds of 158% presenting pre-frailty, and 360% of frailty. Elderly caregivers with depressive symptoms had an increased chance of 242% of presenting fragility. Conclusion: elderly and lonely caregivers with depressive symptoms are more likely to be frail and pre-frail.

title: The association of hand grip strength with functional measures in non-ambulatory children with Duchenne muscular dystrophy

description: ABSTRACT Duchenne muscular dystrophy (DMD) is a disease characterized by progressive loss of muscle fiber, gradually from proximal to distal. Although a few studies have investigated hand grip strength in non-ambulatory DMD patients, a lack of literature was found determining its relationship with functional capacity. Objective: The aim of this study was to determine the associations between hand grip strength and functional measures in non-ambulatory children with DMD. Methods: Hand grip strength was evaluated using a dynamometer in children with DMD. The children with DMD were evaluated with the Turkish version of the Egen Klassifikation Scale Version 2 (EK2) for global functional capacity, the Performance of Upper Limb (PUL) for upper limb functional performance and the ABILHAND-Kids for hand ability. Results: The mean age of 38 DMD children was 12.02 ± 1.99 years. Dominant hand grip strength of the children with DMD was higher than the non-dominant hand (p &lt; 0.05). The EK2 was 13.02 ± 5.50, PUL was 49.86 ± 14.34 and ABILHAND-Kids was 26.81 ± 7.59. Hand grip strength was found to be correlated with the EK2 (p &lt; 0.05). Conclusions: It is known that measuring functional ability and strength in very weak children with DMD has been difficult and complex for therapists/clinicians in the clinical environment. Although there is a moderate correlation, hand grip strength may be used in clinical practice as a practical assessment tool to have an immediate insight into the global functional capacity in non-ambulatory DMD children.

title: Construction of the professional identity of portuguese language teachers during their initial teacher education

description: ABSTRACT This paper presents the results of a research project developed with the objective of understanding, from a teacher identity and cognition perspective, the concepts constructed by pre-service teachers of what it means to be a teacher and teach and learn portuguese in working conditions characterized by social and cultural diversity, as well as economic adversity. The study reveals how two undergraduate students in Letras (a teaching degree which entitles its holders to teach disciplines both in middle and high school) participating in a national teacher education program resorted to representations of the school and teaching in order to build references that constituted the foundations of both their formative experiences as teachers and the mental projections they constructed of their pedagogical work and professional identity. The data analysis focused on the referral processes produced by the participants based on the contrast between their previous and current experiences and expectations, captured by the methodological tools used in the research.

title: Quality of life of institutionalized aged with and without symptoms of depression

description: ABSTRACT Objective: compare the quality of life (QOL) of aged residents in homes for aged people with or without symptoms of depression, and identify social, physical activity; leisure; health and basic activities of daily living (ADL) variables that correlate with QOL scores. Method: cross-sectional study conducted with 101 institutionalized aged. Multiple linear regression was used for data analysis. Results: symptoms of depression changed negatively the QOL in the domains: autonomy; present, past and future activities; social participation; intimacy and total score. Dependent aged presented lower QOL for the performance of ADL in the domains: autonomy; social participation and total score; dancing without limitation of movement; liking the residential and not presenting symptoms of depression were the variables that positively influenced the QOL of the aged. Conclusion: social and psychological support, good living conditions and stimulating assistance can improve the QOL of institutionalized elderlies.

title: Fish oil for human health: omega-3 fatty acid profiles of marine seafood species

description: Abstract The purpose of this study was to investigate the fat contents and fatty acid profiles of the edible meat of 13 different seafood species caught in the Northeastern Mediterranean coast. The fatty acid compositions of seafood species ranged from 27.68% to 36.59% saturated fatty acids, 8.99% to 35.84% monounsaturated fatty acids and 10.69% to 39.57% polyunsaturated fatty acids. Myristic acid (C14:0, 0.93-5.59%), palmitic acid (C16:0, 13.68-23.89%), palmitoleic acid (C16:1n7, 0.85-6.00%), heptadecanoic acid (C17:0, 0.67-2.23%), stearic acid (C18:0, 6.82-10.89%), vaccenic acid (C18:1n-7, 1.05-4.01%), oleic acid (C18:1n-9, 4.87-28.73%), linoleic acid (C18:2n-6, 0.32-2.63%), arachidonic acid (C20:4n-6, 0.22-0,82%), eicosapentaenoic acid (C20:5n-3, 1.72-10.73%) and docosahexaenoic acid (C22:6n-3, 4.07-31.44%) were the most important fatty acids in most of species. All seafood species had high levels of EPA and DHA and much higher total n-3 PUFA than n-6 PUFA content. The ratio of w6/w3 PUFAs ranged from 0.02 in European squid to 0.48 in striped piggy. Atherogenicity (IA) and Thrombogenicity Index (IT) values ranged from 0.40 to 0.87 and from 0.17 to 0.79, respectively.

title: Comparisons of the active components in four unripe raspberry extracts and their activites

description: Abstract Dried unripe raspberry of Rubus chingii, were prepared as the following four extracts: unpurified raspberry extract (URE), purified raspberry extract (PRE), URE after high temperature-high pressure (UPE-H, HTHP), and PRE after HTHP (PRE-H). The total polyphenolic contents (TPCs) and total flavonoid contents (TFCs) of the four extracts, as assessed by colorimetry, significantly increased in the following order: URE &lt; URE-H &lt; PRE &lt; PRE-H. The antioxidant capacity and antibacterial activity were as follows: PRE-H &gt; PRE ≈ URE-H &gt; URE. Moreover, 11 typical polyphenols were quantified using a HPLC-MS analysis showed that HTHP treatments were conducive to releasing more (+)-catechin, (−)-epicatechin, proanthocyanidin B1 and ellagic acid, reaching ~70% ‒1,100%, but decreased the rutin, quercetin-3-O-glucuronide, kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside levels by ~10% –20%. The purification of macroporous resin was beneficial to the enrichment of all polyphenols, by ~30%–300%. Ellagic acid was the main polyphenol found in the extracts, accounting for ~67%-74%. The study indicated that changes in the polyphenols of raspberry extracts after resin purification and/or HTHP treatment were correlated with the extract’s antioxidant capacity and antibacterial activity. Further evaluations of the correlation between bioactive ingredients and treatments should reveal that HTHP and resin purification methods are effective means of preparing extracts.

title: Does caffeine ingestion before a short-term sprint interval training promote body fat loss?

description: We investigated the effect of caffeine ingestion combined with a 2-wk sprint interval training (SIT) on training-induced reductions in body adiposity. Twenty physically-active men ingested either 5 mg/kg of cellulose as a placebo (PLA, n=10) or 5 mg/kg of caffeine (CAF, n=10) 60 min before each SIT session (13×30 s sprint/15 s of rest). Body mass and skinfold thickness were measured pre- and post-training. Energy expenditure was measured at rest, during exercise, and 45 min after exercise in the first SIT session. Body fat was similar between PLA and CAF groups at pre-training (P&gt;0.05). However, there was a significant decrease in body fat after training in the CAF group (−5.9±4.2%, P&lt;0.05) but not in PLA (1.5±8.0%, P&gt;0.05). There was no difference in energy expenditure at rest and during exercise between PLA and CAF groups (P&gt;0.05), but the post-exercise energy expenditure was 18.3±21.4% greater in the CAF than in the PLA group (P&lt;0.05). In conclusion, caffeine ingestion before SIT sessions induced a body fat loss that may be associated with higher post-exercise energy expenditure.

title: CFD simulation on centrifugal pump impeller with splitter blades

description: ABSTRACT The present paper aims to present the analysis and comparison of results of computational simulations using Computational Fluids Dynamics (CFD) in impellers of centrifugal pump. Three impellers were simulated: 1) original impeller, 2) original impeller with splitter blades at outlet; 3) original impeller with splitter blades at inlet. The splitters occupied 30% of the length of the main blades. They were simulated using the ANSYS-CFX software system in 1500 rpm rotational speed and at different flow rates. The turbulence model assumed was the Shear Stress Transport (SST). The results were used to build impeller blade head curves, besides the presentation of pressure distribution and streamline behaviour inside the impeller. It was verified that the insertion of the splitter blades reduced the impeller blade head, mainly the impeller with outlet splitter, whose reduction was more intense.

title: Tracing the material history of MAC USP’s Self-Portrait by Amedeo Modigliani

description: ABSTRACT This two-part article (history and analysis, followed by the interpretation of data obtained via analytical techniques) is a study of Amedeo Modigliani’s Self-Portrait (1919, oil/canvas, 100 x 65 cm2), which belongs to the Museu de Arte Contemporânea of the Universidade de São Paulo (MAC USP). By collating documentation on the work’s provenance, critical sources regarding Modigliani’s approach to painting, and technical-scientific (physicochemical and imaging) analyses, we were able to reassess it in light of the articulation between the work’s materiality and composition. We also managed to throw new light on the work’s critical reception in the 1950s, when it arrived in Brazil and received international exposure - at that time, already part of a Brazilian collection - by means of publications and exhibitions.

title: An exploratory study of the tensions in the selection criteria of problems in Primary School teachers

description: ABSTRACT Problem solving is central to the learning and teaching of school mathematics. Its implementation in the classrooms, however, has been elusive and difficult. One of the factors identified as responsible has been teachers conceptions of the process of solving problems, in which they are valued and related to the development of thought, at the same time that their teaching is carried out as a process. This understanding will influence the selection of problems that the teacher makes. This would play a critical role for its successful implementation; in this paper, we explore the tensions in the selection criteria used by Chilean Primary School teachers. We have built and applied a questionnaire open to those attending a voluntary workshop on the selection of mathematical problems. The analysis of their answers by means of a content analysis reveals that these in-service teachers manifest objectivist, utilitarian and humanistic conceptions about the problems. Also, it is possible to identify the tensions Say/Grow and Security/Challenge and another pair that broadens the vision on the tensions that can emerge in the school context. We conclude that the different perspectives in conceptions promote tensions in the selection of problems, related to how the class is orchestrated, the relationship of the teacher with the school system and between the teacher and the resolution of problems.

title: Reaction of weeds, found in vegetable production areas, to root-knot nematodes Meloidogyne incognita and M. enterolobii

description: ABSTRACT Root-knot nematodes cause great damage to vegetable crops in Brazil, besides having a large range of host plants, such as weeds. Weeds can maintain the inoculums or even favor the multiplication of these nematodes. In this study we evaluated the reaction of selected weed species, present in a vegetable production area, to root-knot nematodes Meloidogyne incognita and M. enterolobii. The trials were conducted in a greenhouse at Embrapa Hortaliças, Brasília-DF, in a completely randomized design with six replicates. Fifteen weed species were evaluated for M. incognita race 1, and 16 weed species were evaluated for M. enterolobii. Two tomato cultivars were evaluated as resistance and susceptibility standards. Gall index (IG), egg mass index (IMO), number of eggs per gram of roots (eggs/g roots) and reproduction factor (FR) were evaluated. M. enterolobii survives and multiplies more easily in weeds collected in vegetable production areas than M. incognita race 1 and, the great majority of weed species evaluated in this study are hosts of both nematode species. Only the species Urena lobata, Sonchus oleraceus, Euphorbia heterophylla, Melampodium perfoliatum and Tagetes sp. were immune to M. incognita race 1. All evaluated species are either hosts or favor the multiplication of M. enterolobii. The species which are the most susceptible to M. incognita race 1, and therefore require greater control of crops infected by this nematode are Ipomoea nil, I. triloba and Eleusine indica, and for M. enterolobii are I. nil, Solanum americanum, Hyptis suaveolens, Portulaca oleracea, I. triloba and Euphorbia heterophylla.

title: Revealing Hercule Florence, Friend of the Arts: X-ray Fluorescence Analysis

description: ABSTRACT The debates about Hercule Florence (Nice, France, 1804 - Campinas, SP, 1879) as the pioneer in the discovery of the photographic process were based mainly on his manuscripts, since few of his épreuves photographiques (photographic experiments) survived. Technological advances in the last four decades have allowed some of his impressions à la lumière solaire to be subjected to analysis by non-destructive techniques at the Instituto de Física of the Universidade de São Paulo in 2016. It was then possible to broaden knowledge of the materials and procedures used in 1833 to obtain the first photographs of the Americas, six years before the announcement of the discovery of the technique by Louis Daguerre in France.
