Resumen El objetivo de este estudio fue evaluar las propiedades fisicoquímicas, morfológicas, estructurales y térmicas del almidón recuperado de los residuos de Solanum tuberosum de la industria de frituras en México, utilizando técnicas instrumentales avanzadas. La papa residual se recogió de una empresa productora de papas fritas y el almidón se obtuvo mediante extracción acuosa. El almidón presentó un contenido de carbohidratos de 87.79 %, proteínas (1.18 %), lípidos (0.15 %), cenizas (0.26 %) y amilosa (24.35 %). La capacidad de absorción de agua fue de 1.0163 g g-1, solubilidad (30.17 - 46.65 %), hinchamiento (2.31 - 8.69 g g-1). Los análisis térmicos mostraron una gelatinización del almidón entre 61.7 - 90 °C con una pérdida máxima de peso a 288.1 °C. La microscopía electrónica de barrido-espectroscopía dispersiva de energía (SEM-EDS) mostró partículas de 14 - 69 µm con una composición de 54.3 % de carbono, 45.4 % de oxígeno y 0.15 % de potasio. La dispersión dinámica de luz (DLS) mostró partículas de tamaño nanométrico (120 nm). La resonancia magnética nuclear (NMR) y la difracción de rayos X (XRD) exhibieron la cristalinidad del almidón como tipo B (34.73 %) y la reflectancia total atenuada por espectroscopia infrarroja transformada de Fourier (FTIR - ATR) mostró los grupos funcionales distintivos de la glucosa.

Abstract The objective of this study was to evaluate the physicochemical, morphological, structural, and thermal properties of starch recovered from Solanum tuberosum residual of chips industry in Mexico using advanced instrumental techniques. The residual potato was collected from a chips production company and the starch obtained by aqueous extraction. The starch presented a content of carbohydrates of 87.79 %, proteins (1.18 %), lipids (0.15 %), ashes (0.26 %), and amylose (24.35 %). The water absorption capacity was 1.0163 g g-1, solubility (30.17 - 46.65 %), swelling (2.31 - 8.69 g g-1). Thermal analyzes showed a starch gelatinization about 61.7 - 90 ºC with a maximum weight loss at 288.1 °C. The scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) showed particles of 14 - 69 µm with a composition of 54.3 % carbon, 45.4 % oxygen, and 0.15 % potassium. The dynamic light scattering (DLS) showed particles of nanometric size (120 nm). The nuclear magnetic resonance (NMR) and X-Ray diffraction (XRD) exhibited the crystallinity of the starch as type B (34.73 %) and the Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) showed the functional groups distinctive of the glucose.

Abstract Peru has a great potential for forestry plantations, nevertheless, importations of this type of products are getting very expensive. Soils under forest are acidic and infertile to support sustainable economically valuable forest tree species such as teak. Information is lacking on proper fertility management in forest plantations such as teak. Therefore, the objective of this study was to explore the effect of lime, and organic and inorganic fertilizers on the early growth and nutrient composition of 12-month old teak grown on acidic soil of Peru. The soil under field study was acidic with a pH of 4.99, low in fertility. A factorial design of 2x3: Lime (No Lime and Liming) and fertilizer (organic, inorganic and mixture), with 9 repetitions was adopted. Tree biometric parameters (height, diameter, biomass) and N, P, K, Ca, Mg, Fe, Cu, Mn, Zn foliar concentrations were determined during early the growth of teak. Treatments with addition of dolomite lime favored higher biometric parameters, and use of organic fertilizers promoted more growth than inorganic fertilizers. In the case of nutrients, no major differences were observed between limed and unlimed treatments while organic fertilizer promoted Ca, K and S nutrition. The results show that the application of lime and organic fertilizers is essential for the successful management and establishment of teak plants in acidic soils of Peru.

Resumo Em algumas situações comunicativas, os oradores empregam afirmações que, dependendo do uso das palavras, podem ser consideradas ofensivas ou agressivas pelos seus interlocutores; além disso, podem ser classificadas como crimes contra a honra, de acordo com o Código Penal peruano (alterado em Agosto de 2021). Este artigo analisa nove declarações avaliadas no crime de difamação feito por Christopher Acosta Alfaro (CAA) a Cesar Acuña Peralta (CAP), ficheiro número 03622-2021-0-1801-JRPE-30, Lima-Peru (2022). Para este efeito, os significados associativos, de acordo com o contexto, são brevemente considerados. O objectivo do estudo é analisar as afirmações como meio de descortesia verbal em relação à proposta de Fuentes (2011) e sob o modelo SPEAKING proposto por Hymes (1962); também, descrever os actos discursivos que a representam. Os resultados indicam que o cotexto, o tipo de discurso, os factores extra-linguísticos, a evidência e a intencionalidade desempenham um papel importante na rotulagem das afirmações como difamatórias. A investigação conclui que a descortesia verbal, em correspondência com actos de fala no crime de difamação, é expressa em ataques ao desempenho profissional, valores, intelecto e relações interpessoais, cujo objectivo é prejudicar, desacreditar e desacreditar a imagem do outro.

Abstract In some communicative situations, speakers use statements that, depending on the use of words, may be considered offensive or aggressive by their interlocutors; moreover, they could be classified as crimes against honor, according to the Peruvian Penal Code (amended in August 2021). This article analyzes nine statements evaluated in the crime of defamation made by Christopher Acosta Alfaro (CAA) to Cesar Acuña Peralta (CAP), with file number 03622-2021-0-1801-JR-PE-30, Lima-Peru (2022). For this purpose, the associative meanings according to the context are briefly considered. The aim of the study is to analyze the utterances as means of verbal discourtesy in relation to Fuentes’ (2011) proposal and under the SPEAKING model proposed by Hymes (1962); likewise, to describe the speech acts that represent it. The results indicate that cotext, type of discourse, extralinguistic factors, evidentiality and intentionality play an important role in denominating utterances as defamatory. The research concludes that verbal discourtesy, in correspondence with speech acts in the crime of defamation, is expressed in attacks on job performance, values, intellect and interpersonal relationships, whose purpose is to damage, discredit and discredit the image of the other.

Abstract: En | Text: En | PDF: En

ABSTRACT Serodiagnosis of strongyloidiasis is usually performed by ELISA for the detection of IgG antibodies due to its high sensitivity and practicality, but its main limitation is a constant source of S. stercoralis antigens. The use of S. venezuelensis as a heterologous source of antigens has facilitated several published studies on the serodiagnosis and epidemiology of human strongyloidiasis. The main objective of this study was to evaluate the diagnostic accuracy of surface cuticle antigens of infective larvae of S. venezuelensis extracted with CTAB detergent (L3-CTAB) in comparison with soluble somatic extracts (L3-SSE) using a panel of sera from immunocompetent and immunocompromised individuals, at three different cut-offs. ROC curve analysis showed that L3-CTAB had an AUC of 0.9926. At the first cut-off value (OD 450 nm = 0.214), sensitivity and specificity were 100% and 90.11%, respectively, with a diagnostic accuracy of 0.93. At a second cut-off value (OD 450 nm = 0.286), sensitivity and specificity were 70% and 100%, respectively, with a diagnostic accuracy of 0.91. However, at an alternative third cut-off value (OD 450 nm = 0.589), sensitivity and specificity were 95% and 97.8%, respectively, with a diagnostic accuracy of 0.97. Using L3-CTAB as an antigenic source, the seropositivity rate in immunocompromised patients was 28.13% (9/32) whereas a seropositivity rate of 34.38% (11/32) was found when L3-SSE was used in ELISA. Therefore, the L3-CTAB is simple and practical to obtain and was found to be highly sensitive and specific.

ABSTRACT: This study evaluated forage-free diets supplemented with sodium bicarbonate (SB) based on ground flint corn on intake, apparent nutrient digestibility, ruminal parameters, and N balance. Four rumen-cannulatedDorper × Santa Inês lambs, with a body weight of 43.4 ± 0.85 kg (mean ± standard deviation) were used. The experimental design was a 4×4 Latin square. Each experimental period lasted 21 days. Experimental diets were: positive control, a diet without SB containing 400 g/kg DM of soybean hulls (CONT), and three diets based on ground flint corn, containing 10 (10SB), 20 (20SB) or 30 (30SB) g/kg DM of SB. Intake of neutral and acid detergent fiber was greater for CONT (P < 0.01) when compared to SB. Intake and apparent nutrient digestibility of dry and organic matter, ether extract, and crude protein did not differ. Intake (P = 0.01) and digestibility (P < 0.01) of non-fiber carbohydrates were greater for SB diets and neutral detergent fiber digestibility was greater (P = 0.03) for CONT. The total digestible nutrients and metabolizable energy were greater for SB (P = 0.04). Rumen concentrations of acetate (P < 0.01), isobutyrate (P < 0.01), butyrate (P < 0.01), isovalerate (P < 0.01), and total short-chain fatty acids (P < 0.01) were greater for CONT. Ruminal pH showed a quadratic (P = 0.05) response to SB levels, with greater values for 20SB. Sodium bicarbonate was efficient in increasing ruminal pH at the level of 20 g/kg DM without interfering with the intake and apparent nutrient digestibility characteristics.

RESUMO: O presente estudo avaliou a suplementação de bicarbonato de sódio (BS) em dietas sem forragem à base de milho moído sobre o consumo e a digestibilidade aparente dos nutrientes, os parâmetros ruminais e o balanço de N. Foram utilizados quatro cordeiros Dorper × Santa Inês, com um peso corporal inicial de 43,4 ± 0,85 kg (média ± desvio padrão). O delineamento experimental foi quadrado latino 4×4. Cada período experimental durou 21 dias. As dietas experimentais foram: controle positivo, sem BS, contendo 400 g/kg de MS de casca de soja (CONT) e três dietas à base de milho moído, sem casca de soja, contendo 10 (10BS), 20 (20BS) ou 30 (30BS) g/kg de MS de BS. O consumo de fibra em detergente neutro e ácido foi maior (P < 0,01)para o CONT quando comparado com BS. O consumo e a digestibilidade aparente da matéria seca, matéria orgânica, extrato etéreo e proteína bruta não diferiram entre os tratamentos. O consumo (P = 0,01) e digestibilidade (P < 0,01) dos carboidratos não fibrosos foram superiores para as dietas contendo BS e a digestibilidade da fibra em detergente neutro foi maior para o CONT. Os teores de nutrientes digestivos totais e energia metabolizável foram superiores para as dietas contendo BS (P = 0,04). A concentração ruminal de acetato (P < 0,01), isobutirato (P < 0,01), butirato (P < 0,01), isovalerato (P < 0,01) e ácidos graxos totais de cadeia curta (P < 0,01) foram mais elevadas para o CONT. O pHruminal apresentou resposta quadrática (P = 0,05) em relação aos níveis de BS, sendo observado maior pH para os animais alimentados com a dieta 20BS. O BS foi eficiente em aumentar o pHruminal no teor de 20 g/kg MS sem interferir no consumo e na digestibilidade aparente dos nutrientes. Portanto, 20 g/kg de MS é a dose indicada de BS em dietas sem forragem para terminação de cordeiros em confinamento.

Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region.

Abstract This comparative-correlational study aims to analyze and compare the relationship between appreciation for sustainable practices (APS) and national identity in two groups of social (n=135) and commercial (n=198) entrepreneurs in Lima-Peru. The results show that social entrepreneurs have higher APS and perceive Peruvians as warmer, more competent, and more moral than commercial entrepreneurs. Self-stereotype of competence and identification with the country explain APS significantly only significant in commercial entrepreneurs. The study analyzes little-explored psychosocial variables for the entrepreneurial phenomenon, proposing strategies to improve sustainability activities in entrepreneurs who do not have a explicit social orientation.

Résumé Cette étude comparative-corrélationnelle vise à analyser et à comparer la relation entre l’appréciation des pratiques durables (APD) et l’identité nationale dans deux groupes d’entrepreneurs sociaux (n=135) et commerciaux (n=198) à Lima-Pérou. Les résultats indiquent que les entrepreneurs sociaux ont des APD plus élevés et perçoivent les Péruviens comme étant plus chaleureux, plus compétents et plus moraux que les entrepreneurs commerciaux. Les compétences autostéréotypées et l’identification au pays expliquent significativement les APD que dans le sous-groupe des entrepreneurs commerciaux. L’étude analyse des variables psychosociales peu explorées pour le phénomène entrepreneurial, en proposant des stratégies pour favoriser les activités de durabilité chez les entrepreneurs qui n’ont pas une orientation sociale de base.

Resumen Este estudio comparativo-correlacional, tiene como objetivo analizar y comparar la relación entre el aprecio por prácticas sostenibles (APS) y la identidad nacional en dos grupos de emprendedores sociales (n=135) y comerciales (n=198) de Lima-Perú. Los resultados indican que los emprendedores sociales presentan mayor APS y perciben a los peruanos como más cálidos, competentes y morales que los emprendedores comerciales. El auto estereotipo de competencia y la identificación con el país explican el APS de manera significativa solo en el subgrupo de emprendedores comerciales. El estudio analiza variables psicosociales poco exploradas para el fenómeno emprendedor, planteando estrategias para favorecer las actividades de sostenibilidad, en emprendedores que no tienen una orientación social de base.

Resumo Este estudo comparativo-correlacional visa analisar e comparar a relação entre e apreço pelas práticas sustentáveis (APS) e a identidade nacional em dois grupos de empreendedores sociais (n=135) e comerciais (n=198) em Lima-Peru. Os resultados indicam que os empreendedores sociais têm APS mais elevado e percebem os peruanos como mais quentes, mais competentes e mais morais do que os empreendedores comerciais. O auto estereotipagem de competência e a identificação com o país explicam a APS significativamente apenas nos empreendedores comerciais. O estudo analisa variáveis psicossociais pouco exploradas para o fenômeno empresarial, propondo estratégias para favorecer atividades de sustentabilidade em empreendedores que não têm uma orientação social básica.

ABSTRACT Nursing homes are institutions with high prevalence of urinary tract infections caused by ESBL-producing E. coli with several virulence factors. The aim of this study was to determine the frequency of the bla CTX-M gene and eight virulence genes in 35 ESBL-producing uropathogenic E. coli from six nursing homes in Peru during 2018. Of the E. coli samples, 57.1% (20/35) were carriers of the bla CTX-M gene. Furthermore, we obtained frequencies of 46% (15/35) and 37% (13/35) for hly-alpha and cnf-1, respectively; we also found high presence of the iucC (63%, 22/35), aer (94%, 33/35) and chuA genes (94%, 33/34) as well as a frequency of 46% (16/35) and 91% (32/34) for the pap GII and nanA genes, respectively. The bla CTX-M gene is predominant and a high frequency of exotoxins gives it a competitive advantage for spreading into the bloodstream.

RESUMEN Los asilos de ancianos son instituciones con una alta prevalencia de infecciones del tracto urinario ocasionado por Escherichia coli productoras de ß-lactamasas de espectro extendido (BLEE), con diversos factores de virulencia. El objetivo del estudio fue determinar la frecuencia del gen bla CTX-M y de ocho genes de virulencia en 35 E. coli uropatógenas productoras de BLEE provenientes de seis asilos en Perú, durante el 2018. El 57,1% (20/35) de las E. coli fueron portadores del gen bla CTX-M. Además, se obtuvo una frecuencia del 46% (15/35) y 37% (13/35) de hly-alfa y cnf-1, respectivamente; elevada presencia de los genes iucC (63%, 22/35), aer (94%, 33/35) y chuA (94%, 33/34) y una frecuencia del 46% (16/35) y del 91% (32/34) de los genes pap GII y nanA, respectivamente. Existe predominancia en la distribución del gen bla CTX-M, además de una alta frecuencia de exotoxinas que le confieren una ventaja competitiva para diseminarse hacia el torrente sanguíneo.

Abstract Objective: To compare pregnancy outcomes among women with and without COVID-19 infection attended in a national level III hospital in Peru. Method: Observational, retrospective and comparative study. RT-PCR positive pregnant women participated in a 1:1 ratio with negative RT-PCR, and 1:2 with pregnant women of 2019. Maternal and perinatal information was collected. Fisher’s exact test was used with a significance level of 0.05 and prevalence ratios (PR) with their confidence interval of 95% (CI95%). Results: 51 pregnant women with positive RT-PCR, 51 with negative RT-PCR and 102 pregnant women in 2019 participated. RT-PCR test were associated to preterm delivery (p < 0.05). The PR for preterm delivery in women with positive RT-PCR compared to pregnant women in 2019 was 3.14 (CI95%: 1.29-7.64); and compared to women with negative RT-PCR was 4.0 (CI95%: 1.13-14.17). Conclusions: The study’s findings suggest the existence of an association between maternal COVID-19 and preterm birth. However, more studies are required to analyze the role of maternal factors.

Método: Estudio observacional, retrospectivo y comparativo. Participaron gestantes con RT-PCR positiva y negativa en razón 1:1, y 1:2 con gestantes del año 2019. Se recogió información materna y perinatal. Se usó la prueba exacta de Fisher con significancia de 0,05 y razones de prevalencia (RP) con intervalo de confianza del 95% (IC95%). Resultados: Participaron 51 gestantes con RT-PCR positiva, 51 gestantes con RT-PCR negativa y 102 gestantes del año 2019. Se observó asociación entre los resultados de la RT-PCR y el parto pretérmino (p < 0,05). La RP de parto pretérmino en las gestantes con RT-PCR positiva fue de 3,14 (IC95%: 1,29-7,64) veces en comparación con las gestantes de 2019 y de 4,0 (IC95%: 1,13-14,17) veces en comparación con las gestantes con RT-PCR negativa. Conclusiones: Los hallazgos sugieren que puede existir asociación entre COVID-19 y parto pretérmino. Sin embargo, se requieren estudios más amplios para analizar el papel de otros factores maternos en esta asociación.

RESUMEN Objetivo: Describir los resultados de la nefrectomía laparoscópica en pacientes con riñones excluidos benignos, malignos y de donantes. Material y métodos: Estudio de serie de casos, retrospectivo, realizado en el Hospital Cayetano Heredia entre agosto del 2013 y mayo del 2019. Se incluyeron pacientes con riñones no funcionantes de cualquier etiología y riñón contralateral funcionante. Se excluyendo pacientes con pionefrosis severa. Se registraron sus características clínicas, demográficas, índice de masa corporal, etiología del riñón no funcionante, tasa de conversión, lateralidad, tiempo operatorio, histopatología de los riñones intervenidos, complicaciones, necesidad de transfusión, estancia hospitalaria y evolución de los pacientes intervenidos. Resultados: Se evaluaron 70 pacientes; en 39 (55,8%) se realizó nefrectomía laparoscópica simple por patología benigna, en 23 (32,8%) nefrectomía radical laparoscópica por cáncer y en 8 (11,4%) nefrectomía laparoscópica donante vivo. En 7 pacientes se tuvo que convertir a cirugía abierta. La media del tiempo operatorio fue 188,94 ± 33,41 min. Los resultados histopatológicos fueron pielonefritis crónica y carcinoma renal. No hubo variaciones clínicamente significativas en los niveles de hemoglobina, hematocrito, urea, creatinina. Las complicaciones según clasificación de Clavien: Grado I: 21(30%), II: 9(12,8%) y V: 1(1,4%). La media del tiempo de hospitalización fue 4,66 ± 2,97 días, con buena evolución postoperatoria en el 85,7% de los pacientes. Conclusión: La nefrectomía laparoscópica para riñones excluidos de patología benigna como maligna y de donantes de riñón, es una técnica mínimamente invasiva, reproducible, segura, efectiva y una alternativa a la cirugía abierta.

SUMMARY Objective: To report the findings of laparoscopic nephrectomies in patients with malignant, benignant and donor conditions. Material and Methods : A retrospective case series carried-out at Cayetano Heredia Hospital between August 2013 and May 2019. Patients with non-functioning kidneys of any etiology and contra lateral kidney functioning were included. Patients with severe pionephrosis were excluded. Demographic, clinical, body mass index, etiology of the nonfunctioning kidney, conversion rate, laterality, operating time, histopathology of the resected kidneys, complications, need for blood transfusion, hospital stay and clinical evolution. Results: 70 patients were evaluated; in 39 (55.8%) a simple laparoscopy for benign entities was performed; in 23 (32.8%) a radical nephrectomy for cancer was performed and in 8 (11.4%) a laparoscopy was performed for living donors. In 7 patients the laparoscopic procedure converted into open surgery. Mean operating time was 188.94 ± 33.41 min. Main histopathological findings were chronic pyelonephritis and renal carcinoma. Complications by Clavien classification were: Grade I: 21(30%), II: 9(12.8%) and V: 1(1.4%). Mean hospital stay was 4.66 ± 2.97 days; 85.7% had good clinical evolution. Conclusion : Laparoscopic nephrectomy for benign and malignant conditions as well as for kidney donors is a minimally invasive technique which is reproducible, safe, effective and therefore represents an alternative to open surgery.
