Produccion y comercializacion de la cebolla amarilla en Nicaragua: Analisis de la produccion y comercializacion de la cebolla marilla en el Valle de Sebaco, Departamento de Matagalpa 2011-2015

La tesis de seminario de graduación pretende analizar la producción y comercialización de la Cebolla amarilla en el Valle de Sébaco, municipio del departamento de Matagalpa, haciendo énfasis en cada uno de los procesos pertenecientes para la obtención de este rubro ya que en ellos se refleja la realidad de las relaciones entre factores en un sistema de producción, comercialización y acceso al mercado. La temática de investigación en este estudio es conocer las debilidades y fortalezas que enfrentan los actores dentro de la producción y comercialización de la cebolla amarilla en el Valle de Sébaco. Uno de los problemas más importantes que enfrentan los productores cebolleros es la imposición del precio de parte de los compradores mayoristas de cebolla amarilla debido al acaparamiento del producto y de las importaciones de cebolla provenientes de los países centroamericanos y en la mayoría de los casos de Holanda, lo que reduce las probabilidades de que los productores nicaragüenses puedan comercializar la cebolla amarilla a nivel nacional. La producción y comercialización de la Cebolla Amarilla en el Valle de Sébaco se compone a partir de 4 eslabones principales los cuales son Insumos y servicios, producción primaria, cosecha y comercialización, a través de estos eslabones se encuentran presente diferentes actores que participan de los procesos pertenecientes a esta actividad. Por último en los mercados locales o municipales que comercializan la Cebolla amarilla al detalle se ubican pequeños comerciantes como pulperías, mini súper y vendedores ambulantes. Por medio de estos canales de comercialización se logra que el producto llegue a su destino final que es el consumidor, los cuales adquieren este producto de primera necesidad en el hogar a distintos precios y calidad. Por medio de este análisis se llegó a la conclusión que a pesar de las distintas limitantes y problemáticas en la producción y comercialización de la Cebolla amarilla, esta como fortaleza que a pesar de los altos costos de producción es una actividad rentable con potencial de mercado debido a la alta demanda que posee por el consumidor tanto nacional como internacional

Soil-Transmitted Helminth Infections and Nutritional Status in School-age Children from Rural Communities in Honduras

Background: Soil-transmitted helminth (STH) infections are endemic in Honduras and efforts are underway to decrease their transmission. However, current evidence is lacking in regards to their prevalence, intensity and their impact on children’s health. Objectives: To evaluate the prevalence and intensity of STH infections and their association with nutritional status in a sample of Honduran children. Methodology: A cross-sectional study was done among school-age children residing in rural communities in Honduras, in 2011. Demographic data was obtained, hemoglobin and protein concentrations were determined in blood samples and STH infections investigated in single-stool samples by Kato-Katz. Anthropometric measurements were taken to calculate heightfor- age (HAZ), BMI-for-age (BAZ) and weight-for-age (WAZ) to determine stunting, thinness and underweight, respectively. Results: Among 320 children studied (48% girls, aged 7–14 years, mean 9.7661.4) an overall STH prevalence of 72.5% was found. Children .10 years of age were generally more infected than 7–10 year-olds (p = 0.015). Prevalence was 30%, 67% and 16% for Ascaris, Trichuris and hookworms, respectively. Moderate-to-heavy infections as well as polyparasitism were common among the infected children (36% and 44%, respectively). Polyparasitism was four times more likely to occur in children attending schools with absent or annual deworming schedules than in pupils attending schools deworming twice a year (p,0.001). Stunting was observed in 5.6% of children and it was associated with increasing age. Also, 2.2% of studied children were thin, 1.3% underweight and 2.2% had anemia. Moderate-to-heavy infections and polyparasitism were significantly associated with decreased values in WAZ and marginally associated with decreased values in HAZ. Conclusions: STH infections remain a public health concern in Honduras and despite current efforts were highly prevalent in the studied community. The role of multiparasite STH infections in undermining children’s nutritional status warrants more research

Soil-Transmitted Helminths, Poverty, and Malnutrition in Honduran Children Living in Remote Rural Communities

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life

Reference interval for immature platelet fraction on Sysmex XN haematology analyser in adult population

Introduction: The Sysmex XN-series haematology analyser has newly adopted a fluorescent channel to measure immature platelet fraction (IPF). To promote the clinical utility of this promising parameter, establishing a reliable reference interval is mandatory. According to previous studies, IPF values may be affected by the employed analyser and the ethnic background of the individual, but no differences seem to be found between individuals’ genders. Therefore, this study aimed to define the reference interval for IPF in a Spanish population following Clinical and Laboratory Standard Institute (CLSI) guidelines. Materials and methods: A total of 153 healthy Caucasian adults from Spain met the inclusion criteria. IPF measurement was performed by means of a Sysmex XN-2000 haematology analyser. A non-parametric percentile method was used to calculate the reference intervals in accordance with CLSI guidelines. Results: The obtained reference interval for IPF on the Sysmex XN-2000 was 1.6–9.6% (90% confidence intervals (CIs) were 1.5–1.8 and 9.3–11.5, respectively). No significant gender difference in IPF reference intervals was observed (P = 0.101). Conclusions: This study provides, for the first time, a reference interval for IPF using a Sysmex XN-2000 in a Spanish population, ranging from 1.6 to 9.6%. These data are needed to evaluate platelet production in several conditions such as thrombocytopenia, inflammatory states and cardiovascular diseases, as well as for future research

Pathogenic variants of DNAJC12 and evaluation of the encoded cochaperone as a genetic modifier of hyperphenylalaninemia

This paper reports the retrospective genetic analysis of a cohort of unsolved cases of HPA. Biallelic variants of DNAJC12 were identified in 20 patients (generally neurologically asymptomatic) previously diagnosed with phenylalanine hydroxylase (PAH) deficiency (phenylketonuria [PKU]). Further, mutations of DNAJC12 were identified in four carriers of a pathogenic variant of PAH. The genetic spectrum of DNAJC12 in the present patients included four new variants, two intronic changes c.298‐2A>C and c.502+1G>C, presumably affecting the splicing process, and two exonic changes c.309G>T (p.Trp103Cys) and c.524G>A (p.Trp175Ter), classified as variants of unknown clinical significance (VUS). The variant p.Trp175Ter was detected in 83% of the mutant alleles, with 14 cases homozygous, and was present in 0.3% of a Spanish control population. Functional analysis indicated a significant reduction in PAH and its activity, reduced tyrosine hydroxylase stability, but no effect on tryptophan hydroxylase 2 stability, classifying the two VUS as pathogenic variants. Additionally, the effect of the overexpression of DNAJC12 on some destabilizing PAH mutations was examined and a mutation‐specific effect on stabilization was detected suggesting that the proteostasis network could be a genetic modifier of PAH deficiency and a potential target for developing mutation‐specific treatments for PKUThis work was funded by grant PI16/00573, B2017/BMD-3721, the Fundación Isabel Gemio and the Fundación La Caixa (LCF/PR/PR16/11110018), an institutional grant from the Fundación Ramón Areces to the Centro de Biología Molecular Severo Ochoa, and the European Regional Development Fun

Treatment Of A Patient With Thoracolumbar Scoliosis Utilizing A Regional Interdependence Approach Including Components Of The Schroth Method: A Case Report

Background and Purpose: Spinal deformity is a challenging spinal disorder in adults. A scoliotic curve of \u3e10 degrees exists in up to 12% of the population and while surgery is the definitive measure, there is limited evidence to guide non-surgical treatment. This case investigated traditional physical therapy (PT) treatment utilizing a Regional Interdependence Approach (RIA) and components of the Schroth method for a patient with chronic low back pain (CLBP). Case Description: A 66 year old male presented with CLBP, worst upon rising in the AM with (6/10 NPRS). Imaging demonstrated thoracolumbar dextroscoliosis, bilateral foraminal narrowing and associated spondylolisthesis of the fifth lumbar vertebrae. A RIA exam revealed mobility deficits of thoracolumbar spine, instability of L5-S1, and a 1.38” leg length discrepancy. A comprehensive treatment approach was used including lumbar stabilization exercises and postural therapy, including components of the Schroth method. Outcomes: Following 12 weeks, pain improved from 6/10 to 4/105, with the patient reporting no pain when arising from bed. 30-second sit to stand improved from five to eight. Following implementation of a shoe lift visible changes were noted in pelvic symmetry. However, the degree of scoliosis appeared unchanged and no subjective improvements were noted on the Roland-Morris Low Back Pain Questionnaire (RMLBPQ)

Here, we show that, unlike the cells with activated MYC oncogene, cells with SMARCA4 inactivation are refractory to the histone deacetylase inhibitor, SAHA, leading to the aberrant accumulation of H3K27me3. SMARCA4-mutant cells also show an impaired transactivation and significantly reduced levels of the histone demethylases KDM6A/UTX and KDM6B/JMJD3, and a strong dependency on these histone demethylases, so that its inhibition compromises cell viability. Administering the KDM6 inhibitor GSK-J4 to mice orthotopically implanted with SMARCA4-mutant lung cancer cells or primary small cell carcinoma of the ovary, hypercalcaemic type (SCCOHT), had strong anti-tumour effects. In this work we highlight the vulnerability of KDM6 inhibitors as a characteristic that could be exploited for treating SMARCA4-mutant cancer patients.Spanish Ministry of Economy and Competitivity-MINECO SAF-2017-82186R PI19/01320Fundacion Cientifica of the Asociacion Espanola Contra el Cancer (AECC) GCB14142170MONTDepartment of Health of the Generalitat de Catalunya 2014SGR364Juan de la Cierva postdoctoral contract IJCI-2016-28201AECC research contract INVES19045ROMESpanish MINECO PRE2018-084624 BES-2015-072204 FPU17/00067Instituto de Salud Carlos III European Commission CM17/00180European Union Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie Actions grant agreement 79985

Evaluación de la producción e inocuidad en frutilla cultivadas con manejo agroecológico

La Inocuidad alimentaria se define como “todas las medidas encaminadas a garantizar que los alimentos no causarán daño al consumidor si se preparan y/o ingieren según el uso al que están destinados” (OMS, 2007). Entre las acciones para contribuir a la inocuidad, la agroecología aporta a producir alimentos saludables de una manera más sostenible. La agroecología a través de herramientas como la implantación de cultivos de servicio y el uso de bioinsumos es útil para nutrir, recuperar y reactivar la vida del suelo, fortalecer la fertilidad de las plantas, y estimular la protección de los cultivos contra el ataque de insectos y enfermedades (Starobinsky y col. 2021).Estación Experimental Agropecuaria SaltaFil: Carmona, Pedro.

Evaluation of different total leishmania amazonensis antigens for the development of a first-generation vaccine formulated with a toll-like receptor-3 agonist to prevent cutaneous leishmaniasis

Unfortunately, no any vaccine against leishmaniasis has been developed for human use. Therefore, a vaccine based on total Leishmania antigens could be a good and economic approach; and there are different methodologies to obtain these antigens. However, it is unknown whether the method to obtain the antigens affects the integrity and immune response caused by them. OBJECTIVES: to compare the protein profile and immune response generated by total L. amazonensis antigens (TLA) produced by different methods, as well as to analyse the immune response and protection by a first-generation vaccine formulated with sonicated TLA (sTLA) and polyinosinic:polycytidylic acid [Poly (I:C)]. METHODS: TLA were obtained by four different methodologies and their integrity and immune response were evaluated. Finally, sTLA was formulated with Poly (I:C) and their protective immune response was measured. FINDINGS: sTLA presented a conserved protein profile and induced a strong immune response. In addition, Poly (I:C) improved the immune response generated by sTLA. Finally, sTLA + Poly (I:C) formulation provided partial protection against L. amazonensis infection. MAIN CONCLUSIONS: The protein profile and immune response depend on the methodology used to obtain the antigens. Also, the formulation sTLA + Poly (I:C) provides partial protection against cutaneous leishmaniasis in mice.Fil: Germano, Maria Jose. Consejo Nacional de Investigaciones Científicas y Técnicas.
