Identificación de variedades del programa mexicano de papa por los patrones electroforeticos de proteínas solubles
Authors: López Humberto , Carrillo Guillermo 
Published: May 2020

Variedades de Solanum tuberosum L. fueron identificadas mediante el análisis electroforético de proteínas solubles del tubérculo. Se utilizaron geles delgados de dodecil sulfato de sodio-acrilamida en su modalidad horizontal. Se estudiaron siete genotipos, los cuales se agruparon en tres grupos por sus características fenotípicas y agronómicas muy similares. Con los patrones de proteínas obtenidos se pudo identificar a cada variedad con excepción de Alpha y AMR-69-1 que mostraron el mismo patrón. La técnica empleada permite analizar simultáneamente 24 muestras por gel, empleando sólo 60 minutos para la separación de las proteínas. Además los geles se hacen en moldes sin utilizar la cámara de electroforesis, lo cual permite preparar los geles y efectuar la separación electroforética de las proteínas simultáneamente. El método es, por tanto, recomendable para el análisis rutinario de proteínas e isoenzimas.

Published: May 2020

En el período 1985-87 se investigó la incidencia de siete virus de papa: PVX, PVS, APMV, APLV, PLRV, PVY y SB-22 en campos y tubérculossemillas comunes de cultivares nativos y mejorados de agricultores de la Sierra Central y Sierra Sur del Perú. Como nativos se consideró el complejo de cultivares de las especies Solanum goniocalyyx, S. chaucha y S. tuberosum ssp. andigena, que son las mas sembradas en las zonas referidas. En general, las muestras resultaron muy infectadas (promedios de 62 a 98% de infección de virus por lote/por zona). PVX fue el virus de mayor incidencia (37-82%), seguido por PVS (19-53%); la incidencia promedio de PLRV y PVY fue de 0.7-6.8%. En particular, PLRV resultó muy difundido en lotes de cultivares nativos (24%). La incidencia del virus denominado SB-22 fue particularmente alta (39%) en el cultivar Ccompis (S. tuberosum ssp. andigena) lo mismo que el APLV (25%) en el cultivar Huayro (S. chaucha). Para APMV se determinó, en las zonas investigadas, una incidencia mediana (3-13%). La incidencia de PVX y PVS fue significativamente mas alta en cultivares mejorados que en cultivares nativos, mientras que la situación con PLRV y PVY fue a la inversa. En Cusco se investigó la incidencia de los virus en campos de papa plantados con tubérculossemillas distribuidos antes de 1986 por proyectos de desarrollo rural y en campos plantados con tubérculos-semillas de agricultores procedentes de ferias, vecinos, y otros. No se encontró diferencias significativas entre ambas categorías. Se discuten los resultados en relación a su relevancia para la producción de tubérculos-semillas de alta calidad fitosanitaria.
Patogenicidad del "nematodo de la oca" (Thecavermiculatus andinus sp. n) en cuatro cultivos andinos
Authors: Franco Javier , Mosquera Papías 
Published: May 2020

Se estudió, bajo condiciones de invernadero la patogenicidad deThecavermiculatus andinus en los cultivos andinos de oca (Oxalis tuberosa Mol.), olluco (OH u cus tuberosas Loz.). quinua (Chenopodium quinoa Willd.) y tarwi (Lupinus mutabilis Sweet.), considerando cuatro densidades de inoculo (5,25,125 y 625 juveniles por gramo de suelo) y un control sin inoculo. La patogenicidad de T. andinus se determinó evaluando el crecimiento linear de las plantas, grosor del tallo, peso del follaje, peso seco del tubérculo y follaje, peso de la raíz y sus rendimientos. Al determinarse este último se extrajo la poblaciónfinal de nematodos, y se desarrolló la curva de reproducción para cada uno de los cultivos.Los resultados mostraron que las diversas densidades causaron diferencias significativas en la expresión de siete caracteres de la oca y olluco, y en seis del tarwi y la quinua. En general una densidad mayor a 25 juveniles por gramo de suelo afectó negativamente todos los cultivos y a medida que ésta se incrementaba la producción disminuía, principalmente en olluco y oca. Por otro lado, la multiplicación del nematodo disminuyó conforme se incrementó el inoculo y que, tanto los intervalos de máxima reproducción como los niveles de equilibrio fueron diferentes para cada uno de los cultivos. Así el olluco se comportó comoel hospedante más eficiente para multiplicar el nematodo T. andinus (41.0x) con respecto al tarwi, oca y quinua (6.0x, 5.0x y 4.0x respectivamente).Aceptado para publicación: diciembre 21,1992
Factores limitantes a la producción y uso de la papa: resultados de la encuesta a los programas nacionales de america latina
Authors: Herrera José E. , Scott Gregory J. 
Published: May 2020

Para ayudar a mejorar la relación entre las necesidades de los países en desarrollo y los objetivos de la investigación agrícola internacional, el Centro Internacional de la Papa (CIP) envió un cuestionario a los líderes de los Programas Nacionales de este cultivo en América Latina, y les pidió su opinión sobre la importancia de 71 factores limitantes a la producción y uso de dicho cultivo. Después de una breve descripción de la metodología empleada, este trabajo presenta los principales resultados de la encuesta. Entre los resultados más sobresalientes está la percepción común de los efectos negativos de precios y producción inestables y la poca importancia que se asigna en el conjunto de países a los nematodos. La información presentada sugiere vínculos más estrechos entre países que enfrentan problemas similares, con el fin de colaborar a diseñar estrategias que optimicen el impacto de la investigación sobre el cultivo y uso de la papa.Aceptado para publicación: febrero 6, 1995
Respuesta del germoplasma de las especies diploides tuberosas de Solanum a la inducción de callos para la manipulación de ploidia
Authors: Orrillo Matilde , Watanabe Kazuo 
Published: May 2020

Materiales genéticos de Solanum diploides, de varios orígenes, incluyendoespecies silvestres, especies cultivadas, haploides provenientes de variedades tetraploides e híbridos entre los mencionados grupos, fueron empleados para duplicar cromosomas in vitro. Para esto se uso ribósido de zeatina, como una parte del programa de mejoramiento de la papa con germoplasma silvestre de Solanum. Para la inducción de callos y la subsiguiente regeneración de brotes en medio sólido, se usaron entrenudos de tallo y segmentos de hoja de plántulas in vitro. Los entrenudos de tallo respondieron mejor que los segmentos de hoja. Losgenotipos híbridos reaccionaron bien en el medio y regeneraron brotes. Los haploides de variedades tetraploides también mostraron alguna respuesta en la formación de callos y en la regeneración de brotes, independientemente de su nivel de endocría. Por otro lado, los genotipos de especies silvestres y sus progenies no mostraron una inducción vigorosa de callos ni regeneración de brotes. La modificación del medio, cambiando las concentraciones de hormonas y de sacarosa no mejoró significativamente la inducción de callos en las especies silvestres y en sus progenies. Parece ser que una amplia variación de alelos es importante para una buena inducción de callos y regeneración de brotes, más que elnivel de endocría. Más aún, los resultados sugirieron que algunos factoreshereditarios están involucrados en la habilidad para crecer en cultivo de tejidos, debido a que esta habilidad de genotipos parentales particulares afectó a sus progenies.Aceptado para publicación: mayo 9, 1996

Published: May 2020

Durante las campañas de 1990-91 y 1991-92, se estudió en la Estación Experimental Toralapa en Cochabamba, Bolivia, la respuesta agronómica de dos variedades de papa, Rosita (spp. tuberosum) y Waych'a (ssp. andigena) a cuatro niveles de nitrógeno y fósforo combinados con dos niveles de potasio. Se observó una respuesta marcada de ambas variedades a la aplicación de nitrógeno y fósforo pero el efecto del potasio sobre el rendimiento no fue significativo Las dos variedades presentaron resultados diferentes en los dos años de prueba mostrando la importancia del efecto varietal y de las condiciones agoclimáticas sobre la respuesta a niveles de fertilización. Los datos de análisis de suelos indican que Waych'a extrae menos fósforo del suelo que Rosita. La relación entre el rendimiento y la duración de cobertura del suelo por el follaje mostró la respuesta de Rosita a niveles de fertilización más altos que Waych'a y parece indicar una mayor eficiencia de Rosita para utilizar la radiación interceptada en la producción de tubérculos.Aceptado para publicación: agosto 1997.
Periodic Triangulations of $\mathbb{Z}^n$
Authors: Dutour Sikirić Mathieu , Garber Alexey 
Published: May 2020

We consider in this work triangulations of $\mathbb{Z}^n$ that are periodic along $\mathbb{Z}^n$. They generalize the triangulations obtained from Delaunay tessellations of lattices. In certain cases we impose additional restrictions on such triangulations such as regularity or invariance under central symmetry with respect to the origin; both properties hold for Delaunay tessellations of lattices.
Full enumeration of such periodic triangulations is obtained for dimension at most $4$. In dimension $5$ several new phenomena happen: there are centrally-symmetric triangulations that are not Delaunay, there are non-regular triangulations (it could happen in dimension $4$) and a given simplex has a priori infinitely many possible adjacent simplices. We found $950$ periodic triangulations in dimension $5$ but finiteness of the whole family is unknown.

Dengue fever is a mosquito-borne disease that occurs in tropical and sub-tropical areas of the world. A severe form of dengue fever, also called dengue haemorrhagic fever, can cause severe bleeding, a sudden drop in blood pressure (shock) and death. The incidence of dengue fever has grown dramatically around the world in recent decades. The purpose of this study was to determine factors affecting prevention practices for dengue fever within the community. A cross-sectional study was conducted in the the municipality of Banda Aceh and district of Aceh Besar, Aceh Province, Indonesia. The sample size was 203, and the study instrument was a questionnaire. The study results showed that female respondents, 71 (75,5%) seem to have practiced prevention of dengue fever more as compared to the males (58,7%) or 64 respondents. Respondents in early adulthood (75 people or 54.7%) practiced more dengue prevention than older respondents. Meanwhile, respondents with higher levels of education, 85 (87.6%) practiced more dengue prevention than respondents with a middle level of education (47.2%) or 50 respondents. Respondents with good knowledge about dengue fever 128 (74%) practiced more prevention of dengue fever than respondent with a poor knowledge (23.3%) or 7 respondents. Respondents who had a positive attitude to the prevention of dengue fever, 108 (85.7%) practiced much more prevention than respondents who had a negative attitude (33.3%) or 25 respondents. Factors most affecting prevention practices for dengue fever were knowledge, attitude, education level, age and gender. Health promotion related to prevention of dengue fever should be done more in the media, especially using televison.

I'tikaaf is a worship maintained by very deep hunger in fasting month of Ramadan. Hunger causes different results on the immune system. This is a prospective study. In this study, the changes in the immune system were investigated during the period of the i’tikaf, which is deep hunger worship. In the last 10 days of Ramadan, before and at the end of i’tikaf blood was taken from 46 male volunteers who performed i’tikaf worship and various biochemical and immunological parameters were examined. Comparison of the measures taken before and after i’tikaf indicated a statistically significant decrease in weight, BMI, waist circumference and hip circumference (p<0.001). Of the hematologic parameters, the lymphocyte count increased significantly (p=0.009). Also, a significant increase was observed in the values of IgA, IgM ve Ig G within the hematological parameters (p<0.001). During the period of i’tikaf, feeding with very low calories (1000 calories) caused an increase in the levels of lymphocyte and immunoglobulins and got the immune system stronger.

In 2005, Ministry of Health introduced the Needle Syringe Exchange Program (NSEP) and Methadone Maintenance Therapy (MMT) program as a part of Harm Reduction program to combat HIV infection in Malaysia among people who inject drug (PWIDs). Expenditures were estimated approximately RM10 millions per year to establish and sustain the NSEP and MMT centres. This study examined the impact of MMT program on preventing HIV seroconversion among registered MMT clients that are people who inject drug (PWIDs), and to identify other predictors of HIV seroconversion among this group. This was a retrospective cohort study done in the state of Perak involving a total of 212 randomly selected MMT clients registered between 2008-2017 in 6 clinics. This study looks at data collected from the last ten-year cohort from baseline to follow-up. A questionnaire was used to obtain socio-demographic data, sexual and drugs abuse history. Test results for HIV were obtained from medical records. Cox regression analysis was performed to examine factors associated with seroconversion and Kaplan-Meier analysis to estimate HIV survival time. This study displayed that both Methadone take home supply (HR 10.4, 95% CI: 1.6 – 68.8) and unprotected sexual practice (HR 5.9, 95%CI: 1.1 – 31.5) shown higher risks of HIV seroconversion compared to DOTS and condom practice among MMT clients respectively. Mean survival for HIV seroconversion among MMT clients was 104.44 (95%CI: 101.85 – 107.04) months. This study provides reliable evidence that MMT program markedly reduces incidence of HIV infection among people who inject drug (PWIDs).

Published: May 2020

Low birth weight (LBW) is one of the most crucial problem related to neonatal mortality and infant mortality. The LBW is defined as babies born with a birth weight less than 2500 grams. LBW does not only contribute to neonatal morbidity, but may lead to neonatal mortality. This study aim to determine the influence of maternal and child health services (MCH) services to neonatal death among LBW babies in Aceh province, Indonesia.This study is observational study with mix method, using quantitative (Unmatched case control study) and qualitative (case study). The study was conducted between 2011-2015 in 8 district/municipality in Aceh Province, Indonesia. Total sample for quantitative study was 500 neonates (1:1), 250 neonates who died in neonatal period (case) and 250 LBW neonates who survived in the neonatal period (control group). Meanwhile, the total sample for qualitative study was 22, there were 12 (mother) and 10 (midwife).The result of A simple logistic regression analysis for MCH factors found that 4 of 7 variable were significant association with neonatal death among LBW (P value < 0.05), these variables include: Antenatal care (ANC), place of delivery, level of health facilities and neonatal visit. Multiple logistic regression found the ANC has a strongest influence on neonatal death among LBW babies in Aceh Province (OR=3.6; 95% CI: 2.3-5.7). The LBW neonates who were born to mothers who received number of ANC equal to or less than 3 times had a 3.6 times higher risk of death, than neonates who were born to mothers who received ANC ≥ 4 times. The appropriate of health services in health facilities are needed to reduce the NMR and improve the health of neonate.
