ABSTRACT The current football can effectively exercise the body of college students and improve their physical health. How to use modern intelligent technology to perform quantitative research on the influencing factors of football on college students' physical health is the current development trend. Based on this, this paper studies the influencing factors of college students' physical health under the intervention of football. First of all, this paper puts forward an analysis model of college students' physical health based on the sarsa algorithm. The autocorrelation function is used to simulate and process the students' physical information. Through the maximum value of the autocorrelation function curve in the detection process, the detection signal is restored, then the error of the sarsa algorithm is analyzed. Secondly, this paper expounds the influence factors of sarsa algorithm on students' physical health in football. Fuzzy evaluation method and analytic hierarchy process are used in the evaluation. Aiming at the shortcomings of AHP, the improved sarsa algorithm is used for comprehensive analysis, and an adaptive simulation evaluation system is established. Finally, the effectiveness of the sarsa algorithm in this system is verified by many football experiments.

Rapid chemome profiling of Cistanche salsa using DI-MS/MS~(ALL) / 中国中药杂志

The current study aims to rapidly and comprehensively profile the chemical composition of Cistanche salsa using direct infusion coupled with MS/MS~(ALL)(DI-MS/MS~(ALL)). The C. salsa extract was directly imported into electrospray ionization(ESI) source of quadrupole time-of-flight(Q-TOF) mass spectrometer with an infusion pump at a flow rate of 10 μL·min~(-1). Acquisition program was applied under negative ionization polarity to collect one MS~1 spectrum(m/z 50-1 200), followed by 1 150 MS~2 spectra with precursor isolation window(m/z 1) amongst mass range m/z 50-1 200. After each MS~2 spectrum was matched to its precursor ion, putative identification was conducted through matching mass spectral data with literature and database. A total of 31 components were identified from C. salsa, including 9 phenylethanoid glycosides, 2 iridoids, 4 saccharides, 9 organic acids, and 7 other compounds, similar to those from C. tubulosa and C. deserticola. In conclusion, DI-MS/MS~(ALL), a facile and reliable analytical tool, can be employed for qualitative analysis of chemical constituents in C. salsa. The research offers a promising strategy to achieve rapid chemome profiling of herbal medicine and provides an alternative source of Cistanches Herba.

Limitations in daily activities, risk awareness, social participation, and pain in patients with HTLV-1 using the SALSA and Participation scales

ABSTRACT Background: Tropical spastic paraparesis or HTLV-associated myelopathy (TSP/HAM) may prevent, limit or restrict the performance of daily living activities, and as a consequence, several aspects of life are affected. Objective: The aim of this study was to evaluate activity limitations, risk awareness, social participation, quality of life, and pain in individuals infected with HTLV-1. Methods: This was an observational, descriptive, analytical, cross-sectional study with a quantitative approach. An interview questionnaire, the Screening of Activity Limitation and Safety Awareness (SALSA) scale, the Participation scale, a quality of life questionnaire (SF-36) and the Brief Pain Inventory were used. Results: A total of 55 patients with HTLV-1 were interviewed (62% asymptomatic and 38% symptomatic). In both groups, there was a higher frequency of patients aged 41-50 years old (35.3% asymptomatic and 38.1% symptomatic), with complete secondary education (47.1% asymptomatic and 42.9% symptomatic), and married (64.7% asymptomatic and 52.4% symptomatic). Of the symptomatic patients, 33.3% were retired; among asymptomatic patients, 20.6% performed domestic activities. The majority of patients in both groups had not received blood transfusions. Sexual intercourse was still practiced by patients. After assessment, asymptomatic patients had no activity limitations (64.7%), and symptomatic patients presented limitations (90.5%). None of the groups showed good risk awareness. There was no restriction on social participation in 97.1% of asymptomatic patients and in 52.4% among symptomatics. Both groups complained of pain, being more frequent in the lumbar spine in asymptomatic patients and in the knees in symptomatic patients. Pain was more severe in symptomatic patients and affected aspects of quality of life. Conclusion: The clinical follow-up instruments must be adopted by healthcare professionals to monitor new symptoms so as to avoid the onset of limitations identified in symptomatic patients, in addition to enabling continuous surveillance of asymptomatic patients.

Reducción de sodio en salsa de tomate y mayonesa mediante la aplicación de un enfoque de umbral sensorial / Sodium reduction in tomato sauce and mayonnaise through the application of a sensory threshold approach

El consumo excesivo de sodio es causa importante de enfermedades no transmisibles incluyendo hipertensión. En esta investigación se evaluó una metodología sensorial para reducir el contenido de sodio en salsas de tomate y mayonesas, productos altamente consumidos en Costa Rica. Se caracterizaron, por triplicado, 16 salsas y 7 mayonesas comerciales para determinar los ingredientes más comunes y sus características físicoquímicas. Se comparó el contenido de sodio reportado en la etiqueta contra el valor determinado experimentalmente. Se formularon prototipos de ambos productos y se determinó el umbral de diferencia apenas perceptible (DAP) para el gusto salado utilizando el método de estímulo constante con 40 panelistas no entrenados (d'= 1, significancia de 0,05 y potencia de prueba de 0,95). Se contruyeron las curvas psicofísicas con concentraciones de sal entre 0,67% y 2,5% para salsa de tomate y 0,13% y 4,16% para mayonesa; obteniéndose DAPs de 0,51% y 0,26% respectivamente; equivalentes a 28,3% y 14,4% menos de sal en cada producto. Para la validación del umbral, se aplicó una prueba de discriminación 2-AFC con 40 panelistas comparando la formulación regular con la reducida en sodio. Los panelistas no detectaron diferencias significativas entre mayonesas (P>0,05) pero sí entre salsas (P<0,05), por lo que se aplicó una prueba de agrado con 112 consumidores y se determinó que la salsa reducida en sodio resultó de mayor o igual agrado que la contraparte. Estos resultados guiarían a la industria alimentaria regional hacia el mejoramiento del perfil nutricional de estos productos(AU)

The excessive consumption of sodium is an important cause of noncommunicable diseases including hypertension. This research aimed, using a sensorial methodology, to reduce sodium content in tomato sauces and mayonnaise, highly consumed products in Costa Rica. A total of 16 commercial sauces and 7 mayonnaises were characterized to determine their most common ingredients and physicochemical properties. The sodium content reported in the labed was compared against values obtained experimentally. Prototypes for both products were developed and the threshold for the just noticiable difference (JND) for salty flavor was determined using the constant stimulus method with 40 panelists (d'= 1, 0.05 significance and a test power of 0,95). Psychophysical curves were built with salt concentrations between 0.67% and 2.5% for tomato sauce and 0.13% and 4.16% for mayonnaise; obtaining JNDs of 0.51% and 0.26% respectively; equivalent to 28.3% and 14.4% less salt in tomato and mayonnaise. To validate the threshold, a discriminatory 2-AFC test with 40 panelists was performed to compare the regular formulations against those reduced in sodium. Panelists did not detect significant differences among mayonnaises (P>0.05) but they did found differences between sauces (P<0.05). Thus, for tomato sauce a consumer liking test with 112 consumers was performed and it was found that sodium reduced tomato sauce was equally or more liked than its counterpart. These results guide the regional food industry towards the improval of the nutritional profile of both products(AU)

Disability due to leprosy: a socio-demographic study in Leprosy Hospital, Chamba, Himachal Pradesh

Background: Leprosy is a chronic granulomatous disease caused by M. leprae bacilli and one of the important cause of preventable disability.Methods: This study was a cross sectional one, conducted at Leprosy Hospital, Sarol, Chamba, Himachal Pradesh over a period of two months, May and June 2018. The study used convenient sampling and all 20 disabled patients who were receiving treatment at Leprosy Hospital were included in the study. Socio demographic data which included age, marital status, occupation, type and duration of disability was collected and analyzed. To screen for activity limitation and safety awareness SALSA scale was used. A score of 25 or more points is indicative of activity limitation and disability.Results: In total 20 patients were evaluated, out of which 12 were male and 8 female and the mean age of patients was 51years. Around 90% of female patients were illiterate and financially dependent while on the contrary 90% male patients were literate and financially independent. All the patients presented with some or severe disability according to Salsa scale. There was significant association of age, education, marital status and employment status with disability.Conclusions: Inspite of elimination of leprosy in India, cases of disability and deformity have not declined as expected. Awareness about warning signs among patients and timely diagnosis by health professionals can curb cases of disability among leprosy patients.

Schinus molle: anatomy of leaves and stems, chemical composition and insecticidal activities of volatile oil against bed bug (Cimex lectularius)

Abstract The present work investigates the leaf and stem anatomy, chemical composition and insecticidal activities (against Cimex lectularius Linnaeus, 1758) of the volatile oils of Schinus molle L., Anacardiaceae, a Brazilian native traditional medicinal plant. Noteworthy micro-morphological features that can help in the identification and quality control of the species include the presence of isobilateral and amphistomatic leaves, anomocytic and cyclocytic stomata, capitate glandular and conical non-glandular trichomes, large secretory ducts in the midrib, presence of druses and prismatic crystals, and the petiole vascular system comprising of five vascular bundles arranged in U-shape and an additional dorsal bundle. The major components of the volatile oil include β-pinene (14.7%), α-pinene (14.1%), limonene (9.4%) and muurolol (11.8%). Insecticidal activities of the volatile oil against bed bugs were investigated for the first time; strong toxicity by fumigation with the volatile oil of S. molle was observed and reported herein.

Assessment of the sensory and physical limitations imposed by leprosy in a Brazilian Amazon Population

Abstract INTRODUCTION Leprosy often results in sensory and physical limitations. This study aimed to evaluate these limitations using a quantitative approach in leprosy patients in Belém (Pará, Brazil). METHODS This epidemiological, cross-sectional study measured the sensory impairment of smell and taste through the use of a questionnaire and evaluated activity limitations of daily life imposed by leprosy through the Screening of Activity Limitation and Safety Awareness (SALSA) Scale. Data were collected from 84 patients and associations between the degree of disability and clinical and epidemiological characteristics were assessed. RESULTS The majority of patients were men (64.3%), married (52.4%), age 31-40 years old (26.2%), had primary education (50%), and were independent laborers (36.9%). The multibacillary operational classification (81%), borderline clinical form (57.1%), and 0 degrees of physical disability (41.7%) were predominant. SALSA scores ranged from 17 to 59 points, and being without limitations was predominant (53.6%). The risk awareness score ranged from 0 to 8, with a score of 0 (no awareness of risk) being the most common (56%). Evaluation of smell and taste sensory sensitivities revealed that 70.2% did not experience these sensory changes. Patients with leprosy reactions were 7 times more likely to develop activity limitations, and those who had physical disabilities were approximately four times more likely to develop a clinical picture of activity limitations. CONCLUSIONS Most patients showed no sensory changes, but patients with leprosy reactions were significantly more likely to develop activity limitations. Finally, further studies should be performed, assessing a higher number of patients to confirm the present results.

Semiaphis dauci (Fabricius) (Insecta, Hemiptera, Aphididae) ­ formal record of occurrence on arracacha (Arracacia xanthorrhiza Bancr) (Apiaceae) in Brazil, morphological characterization, description of damages and arthropods associated to the culture / Semiaphis dauci (Fabricius) (Insecta, Hemiptera, Aphididae) ­ registro formal de ocorrência em mandioquinha­salsa (Arracacia xanthorrhiza Bancr) (Apiaceae) no Brasil, caracterização morfológica, descrição dos danos e artrópodes relacionados à cultura

This paper reports formally the occurrence and describes the damages by Semiaphis dauci (Fabricius, 1775) (Insecta, Hemiptera, Aphididae, Aphidinae, Macrosiphini) on arracacha (Arracaciaxanthorrhiza Bancr.) (Apiaceae) in Brazil. The infestation was initially noted on April/2002 at Núcleo de Produção de Mudas, Departamento de Sementes Mudas e Matrizes, Coordenadoria de Assistência Técnica Integral, Secretaria de Agricultura e Abastecimento, São Bento do Sapucaí, State of São Paulo. Posteriorly the occurrence was detected in other parts of the municipality of São Bento do Sapucaí such as Serrano, Paiol Grande and Cantagalo, being the incidence higher in localities at lower altitudes. The colonies, with large number of individuals, were settled on both sides of the leaves and also hidden under petiole, but with lower number of specimens. The adult plants were underdeveloped and the growing of aphid colonies induced the blossoming. In the seedlings the symptoms were severer with reduction in the development and death of plants. When the colonies were placed in the dorsal side of the leaves, there was a tendency to wrinkling and rolling to upper side that was used as shelter by the aphids. Morphological characterization, illustrations and notes on biology of S. dauci and a survey of the Arthropoda related with A. xanthorrhiza are also presented.

Este trabalho efetua o registro formal de ocorrência e descreve os danos de Semiaphis dauci (Fabricius, 1775) (Insecta, Hemiptera, Aphididae, Aphidinae, Macrosiphini) em cultura de mandioquinha-salsa (Arracacia xanthorrhiza Bancr.) (Apiaceae) no Brasil. A infestação foi observada, inicialmente, em abril/2002, no Núcleo de Produção de Mudas, Departamento de Sementes Mudas e Matrizes, Coordenadoria de Assistência Técnica Integral, Secretaria de Agricultura e Abastecimento, São Bento do Sapucaí, SP. Posteriormente, a ocorrência foi detectada em outras localidades do município como Serrano, Paiol Grande e Cantagalo sendo que a incidência foi maior nas áreas de menor altitude. As colônias estavam localizadas em ambas as faces das folhas, e em menor número no pecíolo escondidas na bainha da folha. As plantas adultas apresentavam subdesenvolvimento e o aumento das colônias induzia o florescimento. Nas mudas os sintomas foram mais severos com redução no desenvolvimento e posterior morte das plantas. Quando havia formação de colônias na superfície superior das folhas, havia tendência de encarquilhamento e enrolamento para cima, servindo de abrigo para os pulgões. Caracterização morfológica, ilustrações, notas sobre a biologia de S. dauci e levantamento dos Arthropoda relacionados com A. xanthorrhiza também são apresentados.

PURPOSE: the vegetal specie, Petroselinum sativum Hoff., known as parsley, is widely used in the Brazilian folk medicine as diuretic. The objective of this study is to verify if Brazilian use of parsley aqueous extract has similar effects with investigations that show a diuretic effect of P. sativum in rats. METHODS: 19 rats were anesthetized and we cannulated the trachea, left carotid artery (for arterial pressure measurement) and urinary bladder (to collect urine). After 40 minutes of adaptive surgery conditions, anesthetized rats were administrated as related with their group: control (CON), oral administration with 1.0 mL of filtered water, and treated group (AE), oral administration with aqueous extract of seeds of parsley 20 percent (AE). Urine was collected three times (30 minutes each) and then this material was used for sodium and potassium determinations, to evaluate the amount excreted of these ions. Blood pressure was measured by mercury manometer for 9 times. All data were statistically evaluated. RESULTS AND CONCLUSION: in the analyzed parameters, CON group did not show any differences; but AE group showed an increased of urinary flow and sodium and potassium amount excreted, and also decreased arterial pressure. All the parameters presented these modifications after 30 minutes of administration of AE (p<0.05). These results show that the treatment with the AE results in natriuretic and hypotensive effects in anesthetized Wistar rats, confirming the use of Brazilian population of this herb as diuretic.

Este trabalho teve como principais objetivos verificar as alterções na atividade de enzimas amilolíticas, pectinolíticas e celulásicas em raízes de mandioquinha-salsa durante o período pós-colheita, sob diferentes condições de armazenamento, visando avaliar os mecanismos de deterioração das raízes, bem como identificar o microrganismo possivelmente responsável pela alta perecibilidade das raízes. Além disso, foram estudadas características físico-químicas e reológicas do amido de mandioquinha extraído em laboratório. Para a detecção de atividade pectinesterásica (PE) e poligalacturonásica (PG) nas raízes, os parâmetros de extração destas enzimas foram otimizados através de metodologia de superfície de resposta (MSR)...

The aim of this work was to verify the changes in amylolytic, pectinolytic and cellulasic activity in Peruvian carrot roots after harvest, under different storage conditions, in order to evaluate the deteriorative mechanisms of the roots, as well as to identify the microorganism possible responsible to its low conservation time. In addition, physico-chemical and rheological characteristics of Peruvian carrot starch were studied. For pectinesterase (PE) and poligalacturonase (PG) detection on the roots, the extraction parameters of both enzymes were optimized by response surface methodology. The enzymes presented the optimum pH values at 7.5 and 4.0 for PE and PG, respectively. Extraction time and NaCI concentration were considered non-significant by the model. Pectic enzymes seams to be related to the deterioration process of Peruvian carrot, that is associated to the root softening. Considering the high volume of gas under specific packing and temperature, the presence of microorganisms soft rot promoters could be the main cause of the high perecibility of the roots. The amylolytic enzymes present an important role on Peruvian carrot deterioration related to the starch hydrolysis and the releasing of reducing sugars, substrate for opportunistic microorganisms. The cellulasic activity was not significant during storage time. Best conditions for roots conservation occurred at 4°C and under vacuum package. The bacteria isolated from the roots were identified by biochemical reactions as Erwinia carotovora subsp. odorifera. Peruvian carrot...
