title: Evaluation of enamel thickness of mandibular incisors

description: ABSTRACT Objective: To measure enamel thickness at the proximal surfaces of the mandibular incisors, using micro-computed tomography (micro-CT) scans. Material and Methods: Forty-one single-rooted mandibular incisors were selected and analyzed according to anatomical characteristics, to form three groups: Group 1 - central incisors (n = 18); Group 2 - right lateral incisors (n = 10); and Group 3 - left lateral incisors (n = 13). First, enamel thickness at the proximal contact areas of the mandibular incisors was measured. Second, the mesial and distal surfaces of the lateral incisors were compared. Finally, the relationship between the tooth width and the mean enamel thickness was determined. Each tooth was scanned with a micro-CT scanner, and the image was processed with SCANCO micro-CT onboard analysis software. Results: There were no statistically significant differences in mean enamel thickness between the mesial and distal surfaces for each lateral incisor, or between contralateral lateral incisors. In all surfaces analyzed, the upper zones had statistically significantly thinner enamel (0.52 ± 0.10 mm) when compared to the middle and lower zones (0.60 ± 0.08 mm and 0.59 ± 0.08 mm, respectively). There was no correlation (r =0.07) between enamel thickness of the mandibular incisor and the tooth width. Conclusions: The enamel thickness of the mandibular incisors is similar on the mesial and distal surfaces, with the thinnest layer located at the upper zone.

title: Simultaneous movement of style and stamen set during anthesis in Etlingera elatior (Zingiberaceae)

description: Abstract Etlingera is a genus of the family Zingiberaceae that is native to tropical Asia. Many species are economically important as a source of food, spices, medicines, and ornamental plants. This study aims to elucidate the floral morphology of E. elatior and understand the behavior of the set of stamen and style during floral anthesis, seeking to identify the mechanisms that promote xenogamy in the species. Flower morphology, time of anthesis and movement of the stamen and style during this period, pollen viability, nectar volume, floral visitors, and the reproductive system were evaluated. The flowers of E. elatior exhibited synchronous movement of the style and stamen, however, this movement was not considered as flexistyly, since the species does not present dichogamy. The synchronous movement of the stamen and pistil, by itself, was not enough to promote self-pollination. Fruiting depends on pollinators. The stigma fluid is an important means whereby pollen adheres to the mouthpart of the pollinator. Hummingbirds and bees were considered the most effective pollinators of E. elatior in the area studied.

title: Agriculture and agroindustry: perspectives of new configuration

description: Abstract This paper presents a reflection about the contemporary agricultural crisis in the developed countries. We try to show that it results not only from the supply/demand disequilibrium, as it is supposed by the majority of the analysts, but also by what we consider as structural factors of the technological modernization pattern. It seems that, by ecological reasons, it is over the historical trend of increasing agricultural labor productivity which allowed the farmers income to rise and the agricultural prices to fall. In these countries the farmers income has been reduced compared to that of urban workers. The only solution for this problem would be transforming the agricultural producers into agro-industrial producers.

title: African migrations in transit through Costa Rica: reflections on the challenges of the institutional care

description: Abstract. In recent decades there has been an increase of the amount of people from different countries from Africa who are transiting the American continent to reach the United States and Canada. Particularly in Costa Rica, since 2014 the presence of these migrations in transit has been more visible, which has produced different institutional responses to control and accompany their transit through the country. This article aims to make visible and problematize some of the main challenges present in the institutional attention to African migrations in transit in Costa Rica. Various interviews were conducted with officials in the area of migration (both from state institutions and international organizations) who have worked with this flow of migrants in the country.. Rather than going into depth on the public policies that permeate this migratory transit, the focus of the article is analyzing the concerns, tensions and contradictions present in the daily attention of this migration and also suggests practices that could strengthen more hospitable horizons with Africans in the country.

title: Intelligent delivery of antitumor drugs mediated by polymeric nanomicelles: a review

description: Cancer therapy represents a challenge, even with the current scientific developments. Over the years, several studies have shown that the application of antitumor drug nanocarriers is an efficient strategy; however, it requires further improvement. Several nanosystems have been developed, some of which are already in use, including liposomes. Polymer-based nanocarriers are still being adjusted to the peculiarities of the human body due to the biological barriers that were encountered by the first systems that were developed. Among them, the formation of corona proteins, clearance by the endothelial reticulum system and kidneys, activation of the immune system, lack of selectivity, and difficult release have been extensively studied and improved with the development of new devices. In this review, we explore the evolution of primary nanocarriers based on polymeric micelles and highlight the gaps that remain in this field to assist in the research of new systems with superior therapeutic indices.

title: Hyperinflation and stabilization

description: ABSTRACT Brazil is undergoing hyperinflation, even though the currency is not dead yet. But for any plan on inflation and stabilization to work, one must acknowledge that the process is hyperinflationary, not just inflationary This paper presents a series of possible ways to overcome this situation, including the need for a permanent fiscal adjustment.

title: Redescription of Vellumnus penicillatus (Gordon, 1930) from Hong Kong and description of a new species from Macclesfield Bank, South China Sea (Crustacea: Brachyura: Pilumnidae)

description: Abstract The poorly known pilumnid, Vellumnus penicillatus (Gordon, 1930), is redescribed by examining the Hong Kong types. A new species, Vellumnus tki n. sp., is described from Macclesfield Bank, South China Sea, and it is distinguished from its closest congener, Vellumnus minabensis (Sakai, 1969) from Japan, by the setal pattern on the carapace and pereiopods, carapace proportions, structure of the front and anterolateral teeth, armature on the chelipeds and relatively shorter ambulatory legs.

title: From Cruzado to Collor: Stabilization Plans and Agriculture

description: ABSTRACT This paper traces the macroeconomic roots of the current agricultural crisis. It shows that the increase in inflationary instability after 1986, and the policies adopted by the Government, since then, to fight hyperinflation, caused the terms of trade of agriculture to be- come much more unstable, at the same time that the Government pulled back the support they had been providing to agriculture; these adverse conditions ultimately caused the reduction of activity levels in agriculture in 1989 and 1990. The paper concludes by pointing out the implications for the current stabilization strategy.

title: Acinic cell carcinoma of the oral and maxillofacial region: an international multicenter study

description: Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region.

title: CRISPR-transient expression in soybean for simplified gRNA screening in planta

description: Abstract The objective of this work was to develop a method to create and validate CRISPR-Cas systems and different gRNAs in soybean (Glycine max) embryos. Two model genes were used for simple mutation with one gRNA or partial gene deletion with two guides. The gRNAs were inserted into the CRISPR transformation vectors by a type IIS restriction enzyme or by subcloning and inserting the promoter + gRNA2 in the final transformation vector using the classic restriction enzyme cloning method. The vectors were successfully constructed for one and two gRNAs. Agrobacterium-mediated transient transformation in soybean was carried out to test the quality of gRNAs and of the system itself (expression cassette). Simple mutation and gene deletion were detected in the embryos transformed after DNA enrichment by enzyme digestion followed by polymerase chain reaction and sequencing, which indicates that the CRISPR-Cas system and guides were working. This protocol can be used to accelerate CRISPR-based genome editing strategies for genetic transformation in soybean.
