RESUMO A qualidade da semente é um fator primordial no sucesso de cultivos. O tratamento de sementes pode contribuir para uniformizar parâmetros de qualidade de um lote de sementes, e por consequência da produção de mudas. Desta forma, o objetivo dessa pesquisa foi avaliar o efeito do tratamento de sementes de diferentes cultivares de pimentão, com doses de ácido salicílico, no potencial fisiológico de sementes e na produção de mudas. Os experimentos foram realizados em duas etapas: em laboratório para avaliação do potencial fisiológico, e em estufa agrícola, para avaliação do efeito dos tratamentos na produção de mudas. Foram utilizadas sementes de pimentão das cultivares All Big e Ikeda. O tratamento de sementes foi realizado com ácido salicílico nas doses de: 0, 0,1, 0,2, e 0,4 (mM). Após o tratamento as sementes foram submetidas a: teste de germinação, e crescimento de plântulas em condições normais e em meio salino (em laboratório). Na segunda etapa as sementes foram utilizadas na produção de mudas de pimentão em estufa agrícola, e avaliou-se: emergência de plantas, altura de plantas, número de folhas, comprimento de raízes, massa seca de plantas, durante 35 dias. Foi possível concluir-se que, nas condições em que foi realizada essa pesquisa não foram observados efeitos de incremento no potencial fisiológico de sementes de pimentão, cultivares All Big e Ikeda, em função do tratamento de sementes com doses entre 0 a 0,4mM de AS; assim como não se observou efeitos positivos de estimulo de crescimento de mudas. Ainda, observou-se redução em alguns parâmetros, tanto em laboratório, quanto em casa de vegetação, com o aumento das doses, especialmente para a cultivar Ikeda, que de maneira geral teve um efeito inibitório com o aumento das doses de AS.

ABSTRACT Seed quality is a key factor for crops success. Seed treatment can contribute to standardizing seed quality parameters, and consequently seedling production. Thus, the objective of this research was to evaluate the effect of seed treatment of different sweet pepper cultivars, with doses of salicylic acid, on the physiological potential of seeds and seedling production. The experiments were carried out in two stages: in the laboratory to evaluate the physiological potential, and in an agricultural greenhouse, to evaluate the effect of treatments on seedling production. Bell pepper seeds of cultivars All Big and Ikeda were used. Seed treatment was performed with salicylic acid at doses of 0, 0.1, 0.2, and 0.4 (mM). After the treatment, the seeds were submitted to germination test, and seedling growth under normal conditions and in a saline medium (in the laboratory). In the second stage, the seeds were used in the production of sweet pepper seedlings in an agricultural greenhouse, and the following were evaluated: plant emergence, plant height, number of leaves, root length, and dry mass of plants during 35 days. It was possible to conclude that under the conditions in which this research was carried out, no effects were observed to increase the physiological potential of sweet pepper seeds, cultivars All Big and Ikeda, as a function of seed treatment with doses between 0 and 0.4 mM of SA; as well as no positive effects of stimulating the growth of seedlings were observed. Furthermore, a reduction was observed in some parameters, both in the laboratory and in the greenhouse, with increasing doses, especially for the Ikeda cultivar, which generally had an inhibitory effect with increasing AS doses.

ABSTRACT Two triatomine genera (Panstrongylus and Triatoma) have essentially been recorded in Rio Grande do Sul State, Brazil. Panstrongylus megistus should be highlighted since this species is one of the main vectors of Trypanosoma cruzi in Brazil, due to its wide geographical distribution and the high susceptibility to this protozoan. This study aimed to present not only the occurrence and distribution of P. megistus in the Porto Alegre city’s metropolitan area (PAMA), Rio Grande do Sul State, Brazil, but also the rates of T. cruzi infection, from 2009 to 2020. The PAMA, which comprises 34 cities and 4.4 million habitants, extends across the transition area in two biomes – Pampa and Mata Atlantica – found in the state. Results showed that P. megistus was recorded in 76.5% of cities (i.e., 26 out of 34), mainly in Porto Alegre city, where the vector was found in 11 out of the 12 years that were monitored. Three hundred and nineteen specimens were captured. Two hundred and sixty-seven specimens (83.7%) were located intradomicile (p < 0.0001), while 52.3% positivity for T. cruzi was found. Thus, P. megistus is important in the PAMA, because it invades and colonizes the households. Moreover, the high rates of T. cruzi infection have drawn attention.

ABSTRACT Triatoma rubrovaria has been captured in some areas of Rio Grande do Sul State (RS), Brazil, as this species can be found in the Pampa biome. Its distribution across this biome should be described in detail to verify the potential of this vector to transmit Trypanosoma cruzi. This study aimed to investigate the occurrence of T. rubrovaria in the Pampa biome and transitional areas of RS. The collected information resulted from the analysis of secondary data provided by the Centro Estadual de Vigilancia em Saude (CEVS – State’s Center of Health Surveillance). The following aspects were taken into consideration: the year in which the insect was captured, the city, the number of specimens captured, invasion or domiciliation, the notification in the household, surroundings or both, and T. cruzi infection. The data comprised the period from 2009 to 2020, in 109 cities located in the Pampa biome and 98 located in transitional areas. The Pampa biome exhibited 85% of the occurrences of T. rubrovaria, while 1.2% of specimens were T. cruzi-like positive. Both the first and second biennia concentrated 64.6% of captures. Alegrete city, Cangucu city and Piratini city were the locations in the Pampa where the largest numbers of specimens were found. Regarding the transitional areas, Roque Gonzales city, Santiago city and Santana da Boa Vista city exhibited the largest numbers. Most insects were adults, which were found in households. Even though positivity for T. cruzi-like was low, the species still has epidemiological importance in the region. RS, RS , (RS) Brazil T CEVS States s Surveillance. Surveillance .

Abstract Sweet potatoes (SP) have gained attention in the media as foods recommended for healthy diets. When preparing the roots for consumption, however, cooking methods do alter their chemical, physical and nutritional properties. In order to assess the changes in carbohydrates of four SP accessions, after common cooking treatments (pressure cooker, convection oven and microwave oven), the contents of sugars and total starch, as well as the starch digestibility were evaluated. The pressure-cooked and convection oven-cooked samples showed high levels of both total reducing sugars (TRS) and soluble reducing sugars (SRS). Among the samples, white pulp sweet potatoes showed the highest starch contents. When cooked by microwave oven without adding water the roots had higher contents of resistant starch (RS). The results demonstrate deep transformations in the carbohydrate profile after cooking, with increase in maltose levels and consequent reduction in starch levels.

Abstract INTRODUCTION: This retrospective study conducted from 2001 to 2018 investigated the residual foci of Triatoma infestans infestation in Rio Grande do Sul, Brazil. METHODS: The data were obtained via entomological surveillance and the distribution of vector occurrence. The coverage of active research was mapped. RESULTS: The largest coverage rate for active research was observed in the northwest region of the total of 515,081 domiciles researched. Most T. infestans specimens were captured in the peridomicile. CONCLUSIONS: Infestation has decreased significantly since 2008, and T. infestans has not been captured since 2015.

ABSTRACT Chagas disease (CD) has been considered endemic in the South of Rio Grande do Sul (RS) State, Brazil. This study aimed at evaluating the occurrence of Trypanosoma cruzi vectors based on the main species captured in Southern Rio Grande do Sul State from 2008 to 2019. The study area comprised counties that belong to the 3rd Regional Health Coordination (RHC) and to the 7th RHC, whose headquarters are in Pelotas and Bage, respectively. The study was based on secondary data provided by the partnership between the Federal University of Pelotas, Rio Grande do Sul State (UFPel-RS) and the State Health Surveillance Center in RS (SCHS-RS). One thousand and four hundred triatomines were captured in the area supervised by the 3rd RHC, mainly in Cangucu (37.7%), Piratini (22.4%) and Pinheiro Machado (15.1%), while, in the area supervised by the 7th RHC, the largest number of triatomines was captured in Lavras do Sul (64.15%). In both areas, Triatoma rubrovaria (90.6%) and Panstrongylus tupynambai (7.4%) were the most common species. Most were captured inside households but T. cruzi-positive insects were not found in the period under study. The results of this study show that, in Southern Rio Grande do Sul State, there is still a high rate of triatomine household invasion and dispersal, mainly by T. rubrovaria. Thus, the entomological surveillance should be maintained with the participation of the population and further studies should be deepened in the area.

RESUMO Racional: A endometriose profunda infiltrativa colorretal pode impactar de maneira importante na qualidade de vida e na fertilidade das pacientes. A ressecção segmentar é uma opção terapêutica com resultados positivos na queda dos sintomas, porém ainda sem efeitos funcionais comprovados. Objetivo: Avaliar o impacto tardio do tratamento laparoscópico da endometriose profunda infiltrativa com ressecção segmentar colorretal. Métodos: Série de casos prospectiva com 46 pacientes submetidas ao tratamento laparoscópico para endometriose profunda infiltrativa com ressecção segmentar colorretal entre 2013 e 2016. Foram analisados sintomas ginecológicos, intestinais e a fertilidade no período pré-operatório, três e 12 meses ou mais após o procedimento. Resultados: Na entrevista pré-operatória, foram levantadas as prevalências de sintomas ginecológicos (87%), intestinais (80,4%) e de infertilidade (45,6%). No 3º mês pós-operatório, observou-se redução significativa da prevalência dos sintomas ginecológicos (p<0,001) e de sintomas intestinais, tenesmo (p=0,001) e disquesia (p=0,002). Após 12 meses ou mais observou-se diminuição significativa da prevalência de dismenorreia (p=0,001), de dispareunia profunda (p=0,041) e de dor pélvica crônica (p=0,011) além de disquesia (p=0,001) em relação ao período pré-operatório. As taxas de gravidez total e espontânea foram de 57,1% e 47,6%, respectivamente. Conclusão: O tratamento da endometriose profunda infiltrativa com ressecção segmentar colorretal proporcionou alívio precoce e tardio dos sintomas ginecológicos e intestinais. Os resultados sugerem impacto positivo sobre a fertilidade em pacientes inférteis.

ABSTRACT Background: Deep infiltrating colorectal endometriosis may severely affect the quality of life and fertility of patients. Although segmental resection is a therapeutic option that provides positive outcomes in the management of symptoms, its functional effects are still unproven. Aim: Assess the late impact of the laparoscopic approach in treating deep infiltrating endometriosis with segmental colorectal resection. Methods: Prospective case series of 46 patients submitted to laparoscopic treatment of deep infiltrating endometriosis with segmental colorectal resection between 2013 and 2016. Fertility, gynecological and bowel symptoms were assessed at the preoperative period and at three and 12 months (or more) after the procedure. Results: Preoperative interview assessed the prevalence of infertility (45.6%), gynecological (87%) and intestinal (80.4%) symptoms. At the third month after the procedure a significant reduction in the prevalence of gynecological symptoms (p<0,001), tenesmus (p=0,001) and dysquesia (p=0,002) was observed. After a period of 12 months or more following the procedure a significant reduction in the prevalence persisted for dysmenorrhea (p=0,001), deep dyspareunia (p=0,041), chronic pelvic pain (p=0,011) and dysquesia (p=0,001), as compared to the preoperative period. Total pregnancy rate was 57.1% and spontaneous pregnancy 47.6%. Conclusion: The treatment of deep infiltrating endometriosis using segmental colorectal resection has provided early and late relief of gynecological and bowel symptoms. The outcomes also indicate a positive impact on the fertility of infertile patients.

ABSTRACT The objective was to analyze the factors associated with the representativeness of the Transformation Zone in cervical screening tests. A retrospective and quantitative study was undertaken through the analyses of the cytopathology tests registered in the Cancer Information System in 2014. The final sample resulted in 1,157 reports. For the data analysis, the software Statistical Package for the Social Sciences was used. Of all tests,96.88% were undertaken for disease control and screening and 24.3% did not present the transformation zone. The factors that influenced the representativeness of the transformation zone were age between 25 and 64 years, use of oral contraception, hormone replacement therapy and metaplastic epithelium. These factors can be considered facilitators to capture a satisfactory sample with the possible reduction of false-negative results, which would entail a delay for the early treatment of cervical cancer.

RESUMEN Estudio cuya finalidad fue analizar los factores asociados a la representatividad de la Zona de Transformación en exámenes de citopatología para control del cáncer de cuello del útero. Es un estudio retrospectivo de carácter cuantitativo realizado por medio de los análisis de exámenes de citopatología registrados en el Sistema de Información del Cáncer en 2014. La muestra final resultó en 1.157 informes. Para el análisis de los datos, se utilizó el software Statistical Package for the Social Sciences . Del total de exámenes, 96,88% fueron realizados para el control y rastreo de la enfermedad y 24,3% no presentaron la zona de transformación. Los factores que influenciaron la representatividad de la zona de transformación fueron edad entre 25 y 64 años, uso de anticonceptivo oral, terapia de reposición hormonal y epitelio metaplásico. Se puede considerar esos factores como facilitadores para la captación de una muestra satisfactoria con la posible disminuición de resultados falso-negativos, lo que resultaría el retraso del tratamiento precoz del cáncer de cuello uterino.

INTRODUCTION: Despite years of efforts towards the elimination of Triatoma infestans in Brazil, residual foci still persist in some areas of the States of Bahia and Rio Grande do Sul. The persistence of these T. infestans populations in the country has two different origins of equal concern: operational failures or insecticide resistance. Thus, the objective of this study was to characterize the susceptibility profile of the residual Brazilian populations of T. infestans to deltamethrin. METHODS: The susceptibility reference lineage was derived from Cipein/Argentina. The populations studied were manually collected using a dislodging agent in peridomiciles in the States of Bahia (Novo Horizonte) and of Rio Grande do Sul (Santa Rosa and Doutor Maurício Cardoso). Serial dilutions of deltamethrin were prepared and applied at the dorsal abdomen of first instar nymphs. The control group received only pure acetone. Mortality was evaluated after 72h. Qualitative tests assessed the mortality of a diagnostic dose of 1xLD99 (2.76ng a.i./nymph) determined for the susceptibility reference lineage. RESULTS: The susceptibility profile characterization of the T. infestans populations revealed an RR50 ranging from 1.73 to 3.26. The mortality percentage in response to a diagnostic dose was 100%. The results obtained in the quantitative and qualitative assays corresponded for all populations. CONCLUSIONS: The results of this study indicate that the persistence of residual foci of T. infestans in Bahia and Rio Grande do Sul is not related to insecticide resistance but may be associated with operational failures. In Rio Grande do Sul, we must consider the possibility of continuous reinfestation by Argentinian individuals, which justifies active and efficient epidemiological surveillance.

O envelhecimento da pele é um processo que preocupa muitos indivíduos, que buscam a ajuda especializada do médico para minimizar seus sinais. Um dos recursos para melhorar a qualidade da pele são os peelings químicos, utilizando várias substâncias ativas, como ácido glicólico, retinóico, tricloroacético e o fenol, entre outros, que proporcionam a esfoliação cutânea e posterior renovação celular. Dependendo da concentração e do valor de pH em que são empregados nas formulações, desencadeiam o peeling superficial, médio e profundo. O fenol tem sido utilizado como peeling profundo tanto isoladamente como em associação com outros componentes da fórmula que atuam como promotores de penetração e permeação. A utilização desses produtos resulta no processo de renovação celular intenso, normalizando a pigmentação da pele, atenuando marcas e minimizando as rugas. Devido a sua toxicidade e contra-indicações, o fenol deve ser aplicado cuidadosamente segundo a técnica recomendada, e o paciente deve ser monitorado para se obter a máxima eficácia do peeling e também minimizar os efeitos sistêmicos.

The natural aging of facial skin is a source of preoccupation for many, who seek out the aid of a specialized physician to minimize its signs. The skin's youthfulness can be obtained using chemical peeling made from various active substances such as glycolic, retinoic, and trichloroacetic acids and phenol. These substances proportion cutaneous exfoliation with subsequent cellular renovation. Depending on the formula concentration and pH value, peelings may be superficial, medium or deep. Phenol has been used in deep peeling. It is the main component of the Baker/Gordon formula, as well as other formula substances acting as penetration and permeation promoters. The use of these active substances results in an intensive process of cellular renovation. It decreases wrinkles, softens the presence of dark spots and gives the skin a youthful appearance. Due to its toxicity and side effects, phenol should be used carefully. Technical steps must be followed. The patient should be monitored in order to obtain maximum effectiveness from the peeling, thereby minimizing effects on the systemic functions.
