RESUMEN

The Big Five Inventory (BFI) is an instrument designed to assess the personality of individuals aged 18 and above. The original version consists of 44 items divided into five sub-scales representing each of the five personality factors: agreeableness, neuroticism, conscientiousness, openness, and extraversion. The main purpose of this study was to assess the factorial structure of the 44-item BFI and the reliability of two shorter versions with 20 and 10 items. The study also aimed to present normative data for interpreting scores from the short and ultrashort versions of the BFI for the Brazilian population. A total of 3565 individuals with a mean age of 33.3 years (SD = 13.0) from all Brazilian states participated in the study, with 44.2% from the State of Rio Grande do Sul. Participants completed a sociodemographic questionnaire and the BFI. Confirmatory factor analysis showed poor adaptation of the original 44-item model, but the short and ultrashort versions with 20 and 10 items respectively had good adaptation indexes and reliability, with Omega coefficients above 0.70. Normative data for the shorter versions were presented using mean, standard deviation, and percentiles (lower, medium, and higher). The study concluded that the short and ultrashort versions of the BFI have good reliability and can be used in surveys requiring a brief personality assessment.

RESUMEN

INTRODUCTION: Anaplastic lymphoma kinase (ALK) rearrangement located on the short arm of chromosome 2, region 2 and band 3 is frequent in lung cancer patients who respond to targeted therapies with ALK inhibitors Therefore, their identification has become a standard diagnostic test in patients with advanced NSCLS, as such chromosomal alterations may lead to the activation of important signalling pathways involved in cell survival and proliferation. METHODS: To investigate the ALK gene status, we performed FISH and IHC assays in 18 lung adenocarcinoma patients, 12 women and 6 men, aged between 29 and 85 years. Paraffin-embedded samples were analyzed in the Pathology Department of the Hospital Universitario San Ignacio. RESULTS: Results between the two techniques in 5 patients showed discordant patterns, being positive for FISH and negative for IHC. The borderline to define ALK positivity was set at 15%, These results present experimental evidence that the techniques differ in specific situations. CONCLUSIONS: Our findings show that it is advisable to investigate the ALK gene status in patients with suspected lung cancer using both FISH and IHC in combination.

RESUMEN

OBJECTIVE: To analyze the microbiological and microstructural part of indwelling urinary catheters and their association with urinary tract infection prevention. METHOD: This is a cross-sectional study, from June to December 2020, in which 42 indwelling urinary catheter tips and sterile urine samples were collected for analysis of crystals in optical microscopy and biofilms in scanning electron microscopy. Culture analysis and specification of the type of bacteria were performed. RESULTS: It was found that 35.71% of the samples had mature biofilm adhered to the catheter tip. Biofilms of Proteus mirabilis, Enterococcus faecalis, Staphylococcus epidermidis, Enterococcus faecium and Enterobacter cloacae stood out. The presence of magnesium-ammonium-phosphate crystal was associated with the presence of urinary tract infection and with Proteus mirabilis. There was a significant association (p = 0.001) between the use of prophylactic antibiotics versus urine culture >105 CFU/mL. CONCLUSION: The analyzes contributed to clinical practice, as it reinforces the development of effective and monitored strategies on cultures and urinary tract infection prevention associated with indwelling urinary catheters.

RESUMEN

The flavonoids are compounds synthesized by plants, and they have properties such as antioxidant, anticancer, anti-inflammatory, and antibacterial, among others. One of the most important bioactive properties of flavonoids is their antioxidant effect. Synthetic antioxidants have side toxic effects whilst natural antioxidants, such as flavonoids from natural sources, have relatively low toxicity. Therefore, it is important to incorporate flavonoids derived from natural sources in several products such as foods, cosmetics, and drugs. For this reason, there is currently a need to extract flavonoids from plant resources. In this review are described the most important parameters involved in the extraction of flavonoids by unconventional methods such as ultrasound, pressurized liquid extraction, mechanochemical, high hydrostatic pressure, supercritical fluid, negative pressure cavitation, intensification of vaporization by decompression to the vacuum, microwave, infrared, pulsed electric field, high-voltage electrical discharges, and enzyme-assisted extraction. There are no unified operation conditions to achieve high yields and purity. Notwithstanding, progress has been achieved in the development of more advanced and environmentally friendly methods of extraction. Although in literature are found important advances, a complete understanding of the extraction process in each of the unconventional techniques is needed to determine the thermodynamic and kinetic mechanisms that govern each of the techniques.

RESUMEN

O estudo teve como objetivo comparar a eficácia do mel e do açúcar mascavo na cicatrização de feridas induzidas cirurgicamente na pele de cobaias, para avaliar o tempo de cicatrização, as variações macroscópicas e microscópicas do tecido cicatricial, a contração das feridas e o grau de contaminação. Quinze cobaias da raça Abissínia, machos inteiros, de seis meses de idade e pesando entre 500 a 850 gramas, foram divididas em três grupos com cinco animais cada, nos quais foram induzidas, cirurgicamente, três feridas em cada animal com dimensão de 1,5cm² e distância entre elas de 1,5cm, na região dorsal. A ferida F1 foi tratada diariamente com mel, a ferida F2 com solução salina 0,9% (controle) e a ferida F3 com o açúcar mascavo. A eutanásia foi realizada no Grupo 1 ao sétimo dia após a cirurgia, no Grupo 2 ao décimo quarto dia e no Grupo 3 no vigésimo primeiro dia após a cirurgia, sendo as biópsias encaminhadas para avaliação histopatológica. Foram também realizados swabs das feridas em todos os grupos no terceiro e sétimo dias após a cirurgia e as amostras enviadas para a cultura e isolamento bacteriano. Concluiu-se que as feridas tratadas com o mel cicatrizaram mais rápido em relação às tratadas com o açúcar mascavo, demonstrando a maior propriedade cicatrizante do mel em relação ao açúcar mascavo.


The study aimed to compare the effectiveness of honey and brown sugar in wounds healing induced in the skin of guinea pigs, to evaluate the healing time, microscopic and macroscopic healing variations, wound contraction and contamination degree. Fifteen guinea pigs, Abyssinia breed, males, six months of age and weighing between 500 to 850 grams, were divided in three groups with five animals each. Three wounds were promoted in each animal, surgical, with 1.5cm² and 1.5cm between them, in the dorsal region. The F1 was treated, daily, with honey, F2 with saline solution 0,9% (control) and F3 with brown sugar. Euthanasia was performed in Group 1 on the seventh day after the surgery, Group 2 on the fourteenth day and the Group 3 on the twenty-first day after the surgery and the biopsies sent to histopathological evaluation. Wounds swabs were made in all groups on the third and seventh days after the surgery and the samples sent for culture and bacterial isolation. The wounds treated with honey healed faster than treated with brown sugar.

RESUMEN

The title compound, [Dy(NO(3))(3)(C(21)H(17)NO(4))(H(2)O)(2)]·C(21)H(17)NO(4), may be considered as an organic-metalorganic 1:1 co-crystal, in which the two dialdehyde mol-ecules act as a ligand and as an organic moiety, respectively. The Dy(III) atom coordinates nine O atoms from the organic ligand, bidentate nitrate ions and water mol-ecules, approximating a square-face-tricapped trigonal-prismatic geometry. The coordinated dialdehyde is not planar: the uncoordinated oxybenzaldehyde group is twisted by 39.96 (4)° from the rest of the ligand. In contrast, the free organic moiety is almost planar, with an r.m.s. deviation of 0.15 Å. In the crystal, segregated stacks of dialdehyde are formed in the [100] direction. For the complex, the shortest π-π contact is found at 3.781 (2) Å, and for the free ligand, at 3.785 (2) Å. The crystal structure is further stabilized by O-H⋯O and O-H⋯N hydrogen bonds in which coordinated water mol-ecules are the donor groups.
