title: Genetic characterization of remaining populations of paratecoma peroba, an endangered and endemic species of the atlantic forest

description: ABSTRACT Background: The objective of this study was the genetic characterization of remaining populations of the species Paratecoma peroba occurring in fragments of the Atlantic Forest, by estimating parameters of diversity and genetic structure. The study was carried out in two forest fragments, the Atlantic Forest Environmental Education Pole (area 1) and the Pacotuba National Forest (area 2), where 93 adult trees were identified. Results: Ten Inter Simple Sequence Repeats (ISSR) primers were used in genotyping, obtaining 112 amplified bands with 87.5% polymorphism. The genetic diversity estimated for the populations from the Nei (H*) and Shannon (I*) indices was higher for area 1. For the joint data, moderate genetic diversity was observed, referring to the average values of 0.26 and 0.40, obtained for the H* and I* indices, respectively. Molecular variance analysis resulted in moderate differentiation between populations (Φ ST = 0.143), while gene flow analysis (N m = 6.69) revealed the occurrence of similar alleles between them. However, the predominance of a single genetic group in area 2, revealed from Bayesian approach, indicates that its genetic structure, possibly generated by the current scenario of fragmentation of the Atlantic Forest and the distancing of populations, affecting the contemporary gene flow. Conclusion: Despite the moderate genetic diversity of the species for the area 2 population, actions toward inclusion of seedlings obtained from seeds from neighboring fragments, including area 1, and the increase in the connectivity of forest fragments through ecological corridors, could assist in augmenting its genetic variation.

title: Analysis of the urban expansion of Marília, São Paulo: a look at the periurban riparian forest remnants

description: Abstract: Due to its locaton, the city of Marília, S P, is located in an important region for water supply in the west of São Paulo, and its urban area advances over the springs, making it necessary to preserve the already degraded and fragmented riparian forests. Thus, the objective was to temporally analyze the landscape in regions of water interest, in order to assess the potential for conservaton of the forest fragments responsible for this resource. A temporal analysis was carried out in the years 1989, 1999, 2009, and 2019, using images from the Landsat 5, 7 and 8 satellites, with 30 m of spatal resoluton. In the ArcMap 10.3 program, land use was grouped into six classes: forest formation, forest plantaton, natural non-forest formation, agriculture, non-vegetated areas, and water. For the entre municipality, landscape metrics CA (land cover) and PLAND (proporton of land cover) were calculated for the six land use classes. An analysis of the forest cover was carried out from a 5 km bufer around the urban area, and five more metrics of area, edge, and shape were calculated. Patich Analyst software version 5.2.0.16 was used to calculate landscape metrics. The classes that most stood out in terms of area size were agriculture (93,962.07 ha; 80.27%), forest formation (15,682.97 ha; 13.40%), and non-vegetated areas (5,220.63 ha; 4.46 %). The largest proportonal increases were in forest planting (0.11 to 1.27 ha), water (0.02 to 0.05 ha), and non-vegetated areas (2.17 to 4.45 ha), while agriculture lost area (85.73 to 80.27 ha). There has been an increase in forested areas in the last 30 years from the appearance of small and morphologically fragile fragments; in additon, with the increase in urban area, conflicts with the nearest forest remnants increase.

title: Fire performance in buildings: academic insights and perspective analysis

description: Abstract: Accelerated growth of urbanizaton and the consequent rise in the number of buildings results on an increase in rapid constructons without minimum criteria that enable the safe building performance and how it behaves during episodes of fre. In this scenario, this paper aims to analyze research trends and the status quo of building fire performance in the last five years, evaluating perspectives for research, and proposals for future directons through a Systematic Literature Review (SLR) approach associated with bibliometric analysis. The analysis was carried out based on the Web of Science database under parameters such as authors, countries and regions, journals, research areas, and keywords. For each rule, among all the results retrieved, those that stood out the most in the stipulated period were evaluated. It was found that research on fire performance in projects is increasing, with a total of 402 published works. In the analysis by Systematic Literature Review, there was a trend of research concerning materials and structural systems, evaluating the performance, behavior, resistance, and safety of buildings under fire conditons. Ultimately, the results pointed out a possible evoluton of the trend in research on methodologies and intelligent control systems applied to the management of fire emergencies.

title: Sundown syndrome and symptoms of anxiety and depression in hospitalized elderly

description: ABSTRACT Sundown syndrome is characterized by the sudden appearance of neuropsychiatric symptoms such as agitation, confusion and anxiety in a chronologic fashion, usually during late afternoon or early evening. Objective: To evaluate the prevalence of sundown syndrome in university hospital wards and its relationship with anxiety/depression symptoms, cognitive decline, and clinical and demographic variables. Methods: We evaluated 70 patients admitted to the Lauro Wanderley University Hospital (HULW), João Pessoa-PB, Brazil. Data collection instruments were the Confusion Assessment Method (CAM), the Mini-Mental State Exam (MMSE) and the Hospital Anxiety and Depression Scale (HADS). Results: Mean patient age was 68.4±6.4 years, 55.7% were male, 67.1% were illiterate or had incomplete primary education. It was observed that 14.3% of patients had delirium, 15.7% had cognitive deficits, while 21.4% and 18.6% had anxious and depressive symptoms, respectively. The age of patients with delirium (71.9±8.7) was significantly higher than those without (67.8±5.8). At 95% confidence, there was a significant difference in the groups with and without delirium for the MMSE and HADS-D scales. Conclusion: We verified the occurrence of delirium compatible with the sundown syndrome and associated with depressive symptoms and cognitive deficit, with no apparent relationship with infectious processes or fever, number of drugs used, hospital stay or anxious symptomatology.

title: Political performance of the Attorney General during democratic transition in Brazil

description: Abstract The paper aims to examine the political performance of the Attorney General (PGR, in Portuguese) during democratic transition in Brazil (1979-1988), based on news coverage. Of particular interest is PGR’s role in judicial review, filtering demands brought to the Supreme Court (STF, in Portuguese), identifying attempts to block the judicialization of politics. Our methodology is based on content analysis of news published in Folha de S. Paulo and O Estado de S. Paulo newspapers, describing aspects of the PGR's performance that reverberated in public opinion. The main finding points to a change in the role of the PGR's over the period, becoming less centered on the criminal prosecution of the regime's opponents and more open to the judicialization of politics, with an intensification of the discourse of moralizing public administration, highlighting cases of political corruption.

title: Sensitivity comparison for the Leishmania spp. detection in different canine tissues using PCR-HRM

description: ABSTRACT Background: Leishmaniasis is a vector-borne disease caused by a parasite protozoon from the genus Leishmania. Among the molecular techniques applied for detecting these parasites, real-time PCR with High Resolution Melting (PCR-HRM) proved advantageous since it simultaneously determines both the presence and species of the pathogen in one step, through amplification and later analysis of curves generated by melting temperature. Methods: Based on this molecular technique, the goal of this study was to estimate the PCR-HRM sensitivity for Leishmania spp. detection in different canine tissues by evaluating biological samples obtained from popliteal, submandibular, and pre-scapular lymph nodes, from bone marrow and ear pinnae of 28 stray dogs captured in the metropolitan area of Asunción (Paraguay). Results: The rk39 immunochromatographic test showed that 25/28 tested dogs (89%) presented antibodies against L. infantum. In 20/25 dogs that tested positive for rk39 (80%), it was possible to detect Leishmania spp. by PCR-HRM and determine that the species corresponded entirely to L. infantum. Regarding the analysis of different tissues, the parasite was detected in all popliteal lymph node samples, followed by high detection in submandibular (at 95%) and pre-scapular lymph nodes (at 90%), bone marrow (at 85%), and ear pinnae (at 85%). Conclusions: This study demonstrated that the use of real-time PCR-HRM using the molecular marker hsp70 was a highly sensitive method for simultaneously detecting and identifying Leishmania species in different tissues taken from infected dogs. In addition, the usefulness of ear pinnae as easily accessible tissue for molecular diagnosis was emphasized.

title: Antineoplastic properties and pharmacological applications of Crotalus durissus terrificus snake venom

description: ABSTRACT Snake toxins are widely studied owing to their importance in snakebite accidents, a serious public health issue in tropical countries, and their broad therapeutic potential. Isolated fractions from venom produced by snakes of the genus Crotalus sp. present a wide variety of pharmacological uses such as antifungal, antiviral, antibacterial, and antitumor properties, among other therapeutic potentialities. Given the direct effect of this venom on tumor cells, isolation of its compounds is important for the characterization of its anticarcinogenic actions. Crotalus durissus terrificus venom and its toxins have been widely evaluated as potential candidates for the development of new antineoplastic therapies that are efficient against different tumor lines and cellular targets. This review highlights the venom toxins of this species, with a focus on their antineoplastic properties.
