title: Lumber Potential of Tropical Species in a Mixed Plantation:Assessment at 50 Months

description: Abstract The use of tropical species in forest plantations is an alternative to supply the demand of good quality wood. However, information regarding the performance of planted tropical species is scarce. The aim of this study was to provide an assessment of the lumber potential of Cariniana legalis (“jequitibá-rosa”), Zeyheria tuberculosa (“ipê-felpudo”) and Cordia trichotoma (“louro-pardo”) in a forest plantation. Three trees per species were sampled at age of 50 months, planted in a mixed stand with 2 x 4 m spacing in Porto Seguro, Bahia, Brazil. We assessed characteristics of the trees, the logs, lumber yield, and partial volumetric shrinkage of wood. Total volumetric shrinkage of ipê-felpudo, jequitibá-rosa and louro-pardo would be around 12.80%, 13.40% and 11.58%, respectively. Among the three species analyzed, louro-pardo had the best performance, followed by ipê-felpudo, while jequitibá-rosa had the worst performance. All species had good performance regarding log quality and dimensional stability of wood.

title: Nursery performance of potentially promising rootstocks for citriculture in the south of Brazil

description: ABSTRACT: Diversification of rootstock varieties, with consequent reduction in phytosanitary risks, has great importance to the sustainability of citrus cultivation in the south of Brazil. This study evaluated the performance of 42 rootstocks in the nursery phase to generate ‘Valencia Late’ sweet orange seedlings. Therefore, nucellar seedlings from the rootstocks under study were analyzed in relation to plant height, stem diameter, mortality rate and percentage of bud set after grafting. The experimental design was completely randomized with four replications of 20 sample units. Not adapted genotypes had high mortality rates, and the ones of both hybrids LCR x CTSW - 009 and LVK x LCR - 038 were 100% and 90%, respectively. Other 13 genotypes had mortality rates above 30%, and ‘Sunki’ mandarin was the female genitor of ten of them. ‘Swingle’ citrumelo was the rootstock with the highest development (plant height and stem diameter), associated with low mortality rate. In relation to the other rootstocks, the best results were the fast grafting diameter, associated with low mortality rate obtained by hybrids HTR - 053, LRF x (LCR x TR) - 005, CLEO x TRBN - 245, CLEO x TRSW - 287, and citrandarins ‘Indio’, ‘Riverside’ and ‘San Diego’, as well as Trifoliate orange and ‘Rangpur’ lime. In addition to Trifoliate orange, which is widely used in Rio Grande do Sul, these rootstocks have great potential in citriculture in the south of Brazil.

title: Tarsal buckling as a complication of surgery to treat congenital ptosis

description: ABSTRACT This paper aimed to report a case of tarsal buckling associated with conjunctival prolapse and upper eyelid inversion as a complication of surgical correction of residual ptosis. A 15-year-old female patient with unilateral residual eyelid ptosis in the right eye, secondary to partial correction of congenital blepharoptosis operated in childhood. The second surgery was performed with resection of the upper eyelid levator muscle aponeurosis, which progressed to conjunctival inversion of the upper eyelid. The structural fragility of the tarsus is the main hypothesis to justify tarsal buckling after surgery. There was complete resolution of tarsal buckling, but persistence of blepharoptosis. Tarsal buckling is an infrequent surgical complication that can occur in correction of blepharoptosis, when there is posterior rotation of the upper half of the tarsus, causing it to curve vertically on its axis and favoring conjunctival prolapse. Establishing diagnosis and early reoperation favor resolution of the condition and avoid possible visual complications.

title: Effect of acupuncture on intraocular pressure and tear production in healthy horses

description: ABSTRACT: Acupuncture is an ancient Chinese form of therapy that involves needle stimulation of specific points on the body for therapeutic and homeostatic effects. In ophthalmology, acupuncture helps as a conventional or adjuvant therapy for numerous eye disorders, including myopia, strabismus, dry eye, and cataracts. This study aimed to evaluate the effect of acupuncture on tear production (TP) and intraocular pressure (IOP) in horses. Ten healthy horses, females and males with ages varying between eight months and nine years, were used. Schirmer’s I test and applanation tonometry were used to evaluate the basal TP and IOP of both eyes. The measurements were taken immediately before (T10) the insertion of the needles and 5 (T5), 15 (T15), 30 (T30) and 60 (T60) minutes and 24 (T24) hours after a 20-minute acupuncture session. Mean values of both eyes were analyzed over time. TP increased in 50% of the animals at T5, T15 and T24, in 30% at T30, and in 40% at T60, with an increase of up to 8.5 mm/min at T15 and T60. In addition, there was a significant difference between T24 and T30, with a 14.1% increase in TP at T24. Meanwhile, IOP decreased in 50% of the animals at T5 and T30, in 20% at T15, in 60% at T60, and in 70% at T24. Thus, we suggest that acupuncture is a technique that can benefit horses with diseases that alter these parameters, either alone or as an adjunct in conventional therapeutic protocols.

title: Niche differentiation between a native and an invasive species of submersed macrophyte in a subtropical reservoir

description: ABSTRACT Submersed macrophytes have important ecological roles but non-native invasive species may affect biodiversity and water uses. We investigated the native macrophyte Egeria najas and the invasive Hydrilla verticillata and measured their maximum colonization depth and its relationship with Secchi disk depth, their biomass along the depth gradient and their preferred depths of occurrence. The Itaipu Reservoir was monitored for seven years, during which maximum colonization depth and Secchi disk depth were measured. During a separate sampling, plants were collected to determine biomass along the depth gradient. Ancova showed that the maximum colonization depth of both species increased with increasing Secchi disk depth, but the maximum colonization depth of H. verticillata increased faster with increasing water transparency than did that of E. najas. Quadratic regression revealed that the biomass of each species peaks at intermediate depths. Hydrilla verticillata colonizes deeper regions than does E. najas. The patterns found in the present study can be explained by underwater light and, probably, wave disturbances. The preference of H. verticillata for deeper sites indicates that the ecological niches of the two macrophytes differ, and that H. verticillata has great potential to spread and accumulate biomass in reservoirs.

title: Sample size for postharvest quality traits of ‘Palmer’ mangoes

description: Abstract The objective of this study was to determine the most efficient sample size required to estimate the mean of postharvest quality traits of ‘Palmer’ mangoes harvested in two growing seasons. A total of 50 mangoes were harvested at maturity stage 2, in winter (June 2020) and spring (October 2020), and evaluated for weight, length, ventral and transverse diameter, skin and pulp L*, C* and hº, dry matter, firmness, soluble solids (SS), titratable acidity (TA) and the SS/TA ratio. According to the results, the coefficient of variation (CV) of fruit quality traits ranged from 2.1% to 18.1%. The highest CV in both harvests was observed for the SS/TA ratio, while the lowest was reported for pulp hº. In order to estimate the mean of physicochemical traits of ‘Palmer’ mangoes, 12 fruits are needed in the winter and 14 in the spring, considering an estimation error of 10% and a confidence interval of 95%. TA and the SS/TA ratio required the highest sample size, while L* and hº required the lowest sample size. In conclusion, the variability was different among physicochemical traits and seasons, implying that different sample sizes are required to estimate the mean of different quality traits in different growing seasons.

title: Virtual mentoring for medical students in the Covid-19 times

description: Abstract: Introduction: Throughout the SARS-COV-2 pandemic, schools had to adopt social distancing and remote learning, which, according to recent studies suggest an increase in depression, anxiety and behavioral disorders among university students. Medical training, which has a heavy load of psychological issues had to face this aggravating factor, reinforcing the need for support actions for students, such as mentoring programs. Mentoring programs offer empathetic and developmental support that encourages self-care, well-being and resilience. Experience report: A group of teacher-mentors from a medical school adapted the mentoring activities to a remote model, offering them to upper-level students who had already participated in mentoring, and, separately, to students who were newly enrolled in the medical course. In the remote format, the mentoring proposal was maintained as a “place of conversation”, but on a digital platform. The technical follow-up was carried out by remote meetings of the group of teacher-mentors, and consultation with students through a self-administered online questionnaire. The data obtained were submitted to content analysis. Discussion: From March to December, 109 virtual mentoring meetings were held. The students considered the meetings satisfactory in terms of the quality of discussions, the mentors’ attitudes and the emotional environment. The interactive development varied among groups, but it was observed to be easier in the groups of upper-level students. Among the newly-enrolled students, the recurring topic was the fear of poor performance in the tests, losing the semester, or not learning. Upper-level students highlighted the difficulties of adapting to remote learning and organizing their activities, and the decrease in practical activities. All groups reported fear of the pandemic, of death, of the worsening of parents’ financial situation, and sadness about the loss of relatives to COVID-19. It drew the attention of the mentors the fact that the students, even in a welcoming space, kept the cameras turned off. Conclusion: For mentors and students, virtual mentoring worked as an important student support system. Upper-level students and first-year ones reported feeling cared for, supported and grateful, suggesting that the meetings allowed a good interaction and produced beneficial effects. A limitation of this study was the duration of the experiment. Therefore, it is recommended that the research be maintained.

title: Maintenance of wetland plant communities: the role of the seed bank in regeneration of native plants

description: ABSTRACT Exotic grasses have been introduced into wetlands and can compete with native plants due to their high tolerance of flood and dry periods. Flooding can facilitate seed dispersal of exotic species and reduce the diversity of native species. We compared two grasslands to assess whether seed banks can maintain the diversity of native plants in wetlands with introduced exotic plants. We recorded a total of 136 species and a predominance of annual plants in the seed bank and vegetation together. The seed bank had high species diversity independently of the dominance of the exotic Urochloa humidicola in the vegetation. The seed banks of the native and cultivated grasslands differed significantly with a positive correlation for aquatic plants in the native grassland and negative correlation in the cultivated grassland. The seed bank revealed potential to maintain the diversity of native species in the cultivated grassland since the flood and dry seasons promoted the presence of distinct species in the seed bank, but lower richness in the vegetation reflects a dependence on the germination stage. The seasonality of flood and dry periods influences distinct growth forms, increasing the diversity of the seed bank and the vegetation.
