Lantana caatingensis Moldenke (Verbenaceae) is an endemic plant from northeastern Brazil. However, its chemical composition is almost unknown. This study aimed to characterize the chemical compounds found in L. caatingensis and investigate the antileishmanial potential of its hydroalcoholic extract and polar fractions. Compounds present in the hydroalcoholic extract obtained from L. caatingensis leaves and its polar fractions (ethyl acetate and methanolic) were analyzed by liquid chromatography with a photodiode-array detector coupled to electrospray ionization quadrupole time-of-flight mass spectrometry. An antileishmanial assay was performed in a 96-well plate against Leishmania major promastigotes using resazurin on a plate spectrophotometer and the results were expressed as percentage of growth inhibition. Nine compounds were determined in the investigated extract and fractions, classified as flavonoids, flavonoid C-glycosides and phenylethanoid glycosides. The antileishmanial activity revealed that the hydroalcoholic extract and the ethyl acetate fraction were active against L. major promastigotes with inhibitory concentration of 71.78 and 26.86 µg mL-1, respectively, while the methanolic fraction was inactive (478.40 µg mL-1). This is the first report on the chemical composition and antileishmanial activity of L. caatingensis extracts. These results contribute to further knowledge of species belonging to the Lantana genus.

In recent years, the field of coordination chemistry has experienced a surge in interest regarding the synthesis and characterization of coordination complexes for diverse applications. This study is dedicated to investigating coordination compounds resulting from the interaction of nonsteroidal anti-inflammatory drugs (NSAIDs) with metal ions. The study research places significant emphasis on understanding the stability and thermal behavior of these coordination compounds. The utilization of thermoanalytical techniques is crucial in achieving this goal. Thermal analysis and thermokinetics provide valuable insights into the underlying mechanisms, kinetics, and energetics of these reactions, thereby facilitating the optimization of synthesis procedures. The research employs concurrent techniques, namely thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), to explore the thermal stability and decomposition pathways of these coordination compounds. Thermokinetic models and optimization methodologies are subsequently applied to identify key reaction parameters. The primary aim of this research is to unveil the thermal behavior, stability, and reaction kinetics of aceclofenac coordination compounds, thus contributing significantly to the understanding of thermokinetics and thermal analysis in the domain of coordination chemistry. Specifically, this study is focused on aceclofenac coordination complexes involving lanthanum and gadolinium, with the ultimate goal of advancing the field of coordination chemistry. years applications antiinflammatory anti inflammatory NSAIDs (NSAIDs ions mechanisms reactions procedures TG (TG DSC, DSC , (DSC) parameters Specifically gadolinium (DSC

ABSTRACT Purpose: This study aimed to determine whether early-stage intraocular pressure can be modulated using a thermal face mask. Methods: In this prospective clinical study, healthy participants were randomized on a 1:1:1 allocation ratio to three mask groups: hypothermic (G1), normothermic (G2), and hyperthermic (G3). After randomization, 108 eyes from 108 participants were submitted to clinical evaluations, including measurement of initial intraocular pressure (T1). The thermal mask was then applied for 10 minutes, followed by a second evaluation of intraocular pressure (T2) and assessment of any side effects. Results: The hypothermic group (G1) showed a significant reduction in mean intraocular pressure between T1 (16.97 ± 2.59 mmHg) and T2 (14.97 ± 2.44 mmHg) (p<0.001). G2 showed no significant pressure difference between T1 (16.50 ± 2.55 mmHg) and T2 (17.00 ± 2.29 mmHg) (p=0.054). G3 showed a significant increase in pressure from T1 (16.53 ± 2.69 mmHg) to T2 (18.58 ± 2.95 mmHg) (p<0.001). At T1, there was no difference between the three study groups (p=0.823), but at T2, the mean values of G3 were significantly higher than those of G1 and G2 (p<0.00). Conclusion: Temperature was shown to significantly modify intraocular pressure. Thermal masks allow the application of temperature in a controlled, reproducible manner. Further studies are needed to assess the duration of these effects and whether they are reproducible in patients with pathologies that affect intraocular pressure.

ABSTRACT Purpose: To evaluate the presence of congenital hypertrophy of the retinal pigment epithelium in a large family affected by familial adenomatous polyposis and identify the causative mutation in the adenomatous polyposis coli gene. Thus, we aimed to determine the significance of congenital hypertrophy of the retinal pigment epithelium as a phenotypic marker of the disease. Methods: A family consisting of 95 individuals was evaluated. Among these, 45 individuals were randomly selected by convenience sampling method to undergo ophthalmological evaluation. A funduscopic exam, including slit lamp and indirect ophthalmoscopy, were performed in the selected patients. In those with retinal lesions, a retinography was obtained. The adenomatous polyposis coli gene was sequenced in one affected family member to identify the pathogenic mutation. Once the variant was identified, six undiagnosed family members were tested for the mutation via capillary electrophoresis sequencing. Results: Congenital hypertrophy of the retinal pigment epithelium was observed in 13 (28.9%) of the 45 individuals evaluated. Of these, nine patients were confirmed to have familial adenomatous polyposis (via colonoscopy or molecular testing). However, four patients had not been investigated. Of the 32 (71.1%) family members without the lesion, 14 did not have familial adenomatous polyposis and 18 were yet to be evaluated. The lesions were bilaterally present and exhibited a peculiar fish-tail shape in all the evaluated individuals. Adenomatous polyposis coli gene sequencing revealed a pathogenic variant c.4031del. (Ser1344*), in heterozygosity (49.27%), in exon 16. Conclusions: The study findings confirmed the significance of congenital hypertrophy of the retinal pigment epithelium as a phenotypic marker for familial adenomatous polyposis. Furthermore, it is an effective first-line screening method for at risk family members of such patients. The novel mutation identified in our study participants, which is yet to be described in the literature, causes an aggressive form of the disease.

This paper presents the stages of an acceleration program focused on chemical technologies. We demonstrate how this initiative contributes to the creation of new businesses, startups, and technology licensing from research developed at Brazilian universities. The case of the program Escale-se is discussed. There were 66 technologies submitted, and 14 were selected for the pre-acceleration phase. In this phase, various contents were worked on, such as creating a business model and aspects of scaling hard-science technologies. Teams were evaluated by panels with market specialists, and 6 were selected for the second phase: pre-scaling/proof of concept. Here, proponents were encouraged to validate the business model by connecting with potential clients and partners, as well as planning the development and testing of the product in a relevant environment. Finally, one team was classified for the last stage: scaling/go-to-market - where they received R$ 100,000.00 to scale up their technology and create strategies for raising investments. Four of the fourteen technologies selected for the program opened National Register of Legal Entities (CNPJ) and raised approximately R$ 4.5 M in investments from different sources. These results demonstrate that the methodology contributed to the entrepreneurial development of participating researchers and the raising of funds for the businesses created. startups universities Escalese Escale se discussed submitted 1 preacceleration pre phase hardscience hard science specialists prescaling/proof prescalingproof scaling/proof proof concept Here partners environment Finally stage scaling/gotomarket scalinggotomarket scaling/go go R 10000000 100 000 00 100,000.0 CNPJ (CNPJ 45 4 5 4. sources created prescaling scalingproof gotomarket scalinggo 1000000 10 0 100,000. 100000 100,000 10000 100,00 1000 100,0 100,

Food contamination is a public health problem, and the search for natural additives to increase food stability and safety is challenging. This research aimed to study nanoemulsions produced with coriander essential oil and kefiran, an exopolysaccharide extracted from kefir grains. The composition of coriander essential oil was evaluated, revealing linalool as the main component. An experimental design consisting of six trials was conducted. The NE2 formulation (0.5% kefiran and 1.5% coriander essential oil) exhibited smaller particle size, monodispersity, a lower centrifugal stability coefficient, and higher absolute zeta potential values (> 30 mV), indicating high electrical stability. Morphology, thermal stability, and toxicity tests were performed. The minimum bactericidal concentration was determined and applied to commercial cheese. Thermal stability tests demonstrated an increase in the stability of NE2 compared to its individual components, and it was also proven to be non-toxic. The concentration of 25% m v-1 was identified as the minimum bactericidal concentration and was applied to commercial cheese. problem challenging grains evaluated component conducted NE 0.5% 05 0 5 (0.5 15 1 1.5 size monodispersity coefficient > ( 3 mV, mV , mV) Morphology performed cheese components nontoxic. nontoxic non toxic. toxic non-toxic 25 v1 v v- 0.5 (0. 1. 2 0.

ABSTRACT: The development of a selection strategy and to obtain a precocious white oat progenies, homogeneous for flowering and with additions to panicle grain mass, reconciled to environmental stimuli controlled by air temperature. The experiment was conducted in the municipality of Augusto Pestana, in the state of Rio Grande do Sul, Brazil. The experimental design was in augmented blocks with intermediate control, the regular treatments corresponded to 238 white oat progenies and the common treatment was represented by the commercial control (URS Taura) arranged in three replications. The selection for grains weight per panicle, percentage of flowered plants, days to physiological maturity and accumulation of degrees day are due to a high genetic contribution, which indicated promising selection for these characters already in initial breeding generations. The accumulation of degrees days for physiological maturity defines that 41.94% of the progenies are selected as precocious. The genotype ideotype distance index (MGIDI) selected 20% of the white oat progenies with greater flowering uniformity, less accumulation of degrees days and high potential for grain mass per panicle.
