Abstract: The differentiation of closely related Citrus genotypes is a meticulous, laborious, and time-consuming task that involves the assessment of complex traits such as growth, tolerance to stress, photosynthetic efficiency, yield, and many others. Such a task is generally accomplished either by analyzing specific features of adult plants or by applying molecular markers to young trees. On one hand, only after plants start yielding can distinct genotypes be differentiated by comparing their fruit sizes, shapes, taste, and the number of seeds. On the other hand, molecular markers are expensive, and demand expertise and time for the analysis of a larger number of plants. For these reasons, the development of techniques that could assist in an early, quick and accurate differen-tiation of closely related Citrus varieties is of utmost importance. In this context, laser-induced fluorescence spectroscopy (LIFS) is a promising technique, since it is rapid, highly sensitive, and inexpensive. Previous studies showed that LIFS can differentiate a variety of sweet orange. However, this new study aimed to determine LIFS accuracy in the differentiation and grouping of very closely varieties of four Sunki mandarin selections: Comum, Florida, Tropical, and Maravilha. Furthermore we compared the results with ISSR and SSR molecular markers for the same varieties. LIFS technique distinguished the four selections with accuracy greater than 70%. Only with molecular markers was possible distinguishing clearly Tropical from Maravilha, but not Comum from Florida selections. In this way the results suggest that LIFS may be a sound tool for helping the identification of closely Citrus varieties.

Abstract: Background: In the year of 2015, evidence of a relation between Zika virus and the development of microcephaly in pregnant women who acquired the infection started to come up. Thus, it is extremely necessary that the analysis of the affliction affects these women in a biopsychosocial context, in order to discuss and comprehend in a more reliable manner the affection from the perception of the disease, origin, and psychic pain mechanisms. Methods: Systematic review with meta-analysis, using the PRISMA protocol. The study period was 2016 and the keywords included “microcephaly” and “abortion”, one at a time and then combined with the Boolean operator “AND.” The statistical analysis was done using the BioEstat 5.0 program. Calculation was based on an adjustment of Mantel-Haenszel random effect. Results: 41,046 registrations were found. Of this total, 40,992 articles were excluded because they only mentioned the fact or referred to spontaneous abortion, did not analyze abortion on the eyes of microcephaly, only treated with Zika virus, or were repeated. Limitations: Psychic pain and suffering need studies in the mother/son/disease relation, which were not found in the databases. The article was based on other sources. Conclusions: The pains vary in different areas of the female life, since internal conflicts, gender violence, stress, fear, insecurity, psychologic torture, grieve, loneliness, among other kinds of psychic suffering. More studies on psycho-emotional themes need to be promoted to discuss the female suffering on a wider vision, closer to the reality faced by these women.

Abstract: This study aimed to investigate the speech perception and subjective preference of unilaterally deafened cochlear implant users for two different speech coding strategies. Thirteen subjects who received a cochlear implant were provided with 2 maps that differed in the speech coding strategy, FS4 or FS4-p (MED-EL). Subjects were requested to alternate between the two maps daily for two weeks and to complete a questionnaire daily. Speech perception testing was performed using the adaptive Bamford-Kowal-Bench speech-in-noise test (BKB-SIN) after two weeks of alternating FS4/FS4-p use. The subjective benefit of FS4-p was significantly greater than the subjective benefit of FS4 on all five questions of the questionnaire. There was a significant improvement in speech perception scores over time under the S0/N0, S0/NHE, SCI/NHE test conditions. There was no significant difference between the speech perception scores obtained with FS4 and FS4-p coding strategies. For this group of cochlear implant recipients, assessment of the subjective preference for the speech coding strategy is likely to enhance motivation, compliance and consequently, outcomes.
