This research aims to deepen knowledge on the role of fear on ART adherence of patients who live in Maputo district in Mozambique, including differences on age, gender and schooling level, on their previous knowledge about HIV and ART and on the impact of the discrimination experiences on the ART adherence. The participants are 602 ART patients living in Maputo district between 21 and 56 years old. The findings reveal that more men than women have interrupted the treatment. Those who did it at least once have more than 39 years old. There are more reports of non-interruption of the treatment on patients who have never been to school or who have been in the high school or more advanced studies. Those who reported that have never interrupted the treatment have more previous knowledge about HIV and the treatment;have never been discriminated and have less fear of being marginalized by being HIV+. Most of those who have interrupted the treatment have already been discriminated by nurses or friends. As fear is automatically processed in our brain, specific contexts of fear related to ART where studied as well as the impact of the fear of those contexts on the behaviors of adherence or of treatment interruption. The results reflect the need to develop national educational policies regarding emotional awareness, adequate emotional support and coping strategies in the context of Fear and of ART adherence. New policies need to address gender and age differences as well as health education access to ART patients, attempting to the stigma and the fear of discrimination as a present element of influence on ART adherence. The study also validates the role of health professionals as high responsible elements on the health of the ART individuals.

AIM: To correlate gastric contractility, gastrointestinal transit, and hormone levels in non-pregnant(estrous cycle) and pregnant rats using noninvasive techniques. METHODS: Female rats(n = 23) were randomly divided into(1) non-pregnant,(contractility, n =6; transit, n = 6); and(2) pregnant(contractility, n = 5; transit, n = 6). In each estrous cycle phase or at 0, 7, 14, and 20 d after the confirmation of pregnancy, gastrointestinal transit was recorded by AC biosusceptometry(ACB), and gastric contractility was recorded by ACB and electromyography. After each recording, blood samples were obtained for progesterone and estradiol determination. RESULTS: In the estrous cycle, despite fluctuations of sex hormone levels, no significant changes in gastrointestinal motility were observed. Days 7 and 14 of pregnancy were characterized by significant changes in the frequency of contractions(3.90 ± 0.42 cpm and 3.60 ± 0.36 cpm vs 4.33 ± 0.25 cpm) and gastric emptying(168 ± 17 min and 165 ± 15 min vs 113 ± 15 min) compared with day 0. On these same days, progesterone levels significantly increased compared with control(54.23 ± 15.14 ng/m L and 129.96 ± 30.52 ng/mL vs 13.25 ± 6.31 ng/mL). On day 14, we observed the highest level of progesterone and the lowest level of estradiol compared with day 0(44.3 ± 15.18 pg/mL vs 24.96 ± 5.96 pg/mL). CONCLUSION: Gastrointestinal motility was unaffected by the estrous cycle. In our data, high progesterone and low estradiol levels can be associated with decreased contraction frequency and slow gastric emptying.

Use of Ultrasound Bath in the Extraction and Quantification of Ester-Linked Phenolic Acids in Tropical Forages

引用

American Journal of Analytical Chemistry 2011年第3期2卷 344-351页

作者： Mellina Damasceno Rachid Santos Aline de Paula Vitor Jailton da Costa Carneiro Domingos Savio Campos Paciullo Renato Camargo matos Maria Auxiliadora Costa matos NUPIS(Nucleo de Pesquisa em Instrumentacao e Separacao Analiticas) Departamento de QuimicaInstituto de Ciencias ExatasUniversidade Federal de Juiz de ForaJuiz de ForaBrazil EMBRAPA—Centro Nacional de Pesquisa de Gado de Leite(CNPGL) Juiz de ForaBrazil

A method was developed for the analysis of ester-linked phenolic acids in forage samples using extraction by an ultrasound-assisted treatment and quantification by HPLC with a UV-VIS detector. A reversed-phase C18 column was used for developing the method and the optimal condition was established with isocratic elution using acetonitrile/methanol/H3PO4 pH 2.08 (13:12.5:74.5) as the mobile phase. To reduce the time of sample processing, the extraction of ester-linked phenolic acids was studied using ultrasound bath and the results were then compared with those from an extraction usual using alkaline hydrolysis (20°C for 24 h). The method was valued through external and internal calibration. Internal calibration using o-coumaric acid as internal standard and m-coumaric acid as surrogate internal standard showed better results. The detection limits were of 0.09 and 0.04 mg●L-1 for p-coumaric and ferulic acids, respectively. The proposed method showed a good linear dynamic range (3.00 - 30.00 mg●L-1) for the analytes. The usefulness of the methodology was demonstrated by addition-recovery experiments using forage samples and values were in the 83 to 99% range. The extraction of ester-linked phenolic acids by 120 minutes of ultrasound bath was faster and more reproducible than alkaline hydrolysis (20°C for 24 h).

Residual Stress and Fracture Toughness Study in A516 Gr70 Steel Joints Welded and Repaired by Arc Processes

引用

Engineering（科研） 2023年第11期15卷 749-758页

作者： Régis de matos Curvelo de Barros Mauricio David Martins das Neves Center for Materials Science and Technology-IPEN Energetyc and Nuclear Research Institute (IPEN) S&atildeo Paulo University S&atildeo Paulo Brazil

Structural components made of steel are used in several areas and require welding for assembly. In some situations, repair of the weld bead, also performed by electric arc welding, can be used to correct, and eliminate any discontinuities. However, electric arc welding causes the presence of residual stresses in the joint, which can impair its performance and not meet specific design requirements. In this paper, welded joints made of ASTM A 516 GR 70 steel plates, with a thickness of 30.5 mm, welded by the MAG—Metal Active Gas process (20% CO2) and using a “K” groove were analysed. The joints were manufactured with seven welding passes on each side of the groove. After welding, one batch underwent repair of the bead by TIG welding (Tungsten Insert Gas) and another batch underwent two repairs by TIG welding. Were presented results of the behaviour of the residual stress profile measured by X-ray diffraction and the Vickers microhardness profile in the joints as well the fracture toughness in the conditions only welded and submitted to repairs. The results indicated that the greater number of repair passes reduced the residual compressive stress values obtained in the material manufacturing process and caused a stabilization on the Vickers hardness values. It was concluded that compressive residual stresses did not play a major role in the R-curve results. The presence of discontinuities in the welded joint caused greater influence on the behaviour of the R curve.
